My Life at Renda
I learned very quickly that being a teaching assistant (TA) at the University of Iowa would be different from being a teacher at Renmin University.
(1) Eyes staring, mouths open, students examined my big nose, while I was writing my name on the blackboard.
At Iowa, when my first classes began, half of my students still hadnt arrived. When everyone finally found a seat, ringing cellphones and loud yawns (哈欠) interrupted my opening remarks. It is not that American students were disrespectful. (2) They were, however, far more skeptical than the students I had at Renda. The truth is I couldnt fault them for their skepticism. Undergraduates at large US universities - especially freshmen and sophomores - often have several classes a semester handled by TAs. In some cases, the TA sets the course content.
(3) Most have good intentions, but very few are as effective as professors.
Every teacher has to confront obstacles to learning - no matter what the culture. Students who talk during lectures, students who cheat, students who question the grade they get for a paper or project - dealing with these is all part of the job. (4)
The difference, I think, is that in the US I had to swallow more of my pride. (5)
I had a responsibility to teach them, of course, but I had to do so indirectly -as a guide who himself had a few things to learn from the students.
A Back at Renda, I had walked into my first classes feeling like a celebrity
B In my students minds, I had little to offer them, except perhaps some sample questions for the mid-term exam.
C In others, the TA works as a grader and discussion leader
D I encountered these in China, and I faced them in the US.
E On the other hand, being taught by a graduate student is not necessarily bad
F Most were polite, or at least, indifferent.
参考答案：F E B C A
Why So Many Children? 为什么有这么多的孩子
In many of the developing countries in Africa and Asia , the population is growing fast . The reason for this is simple ： Women in these countries have a high birth rate — from 3. 0 to 7. 0 children per woman . The majority of these women are poor , without the food or resources to care for their families .Why do they have many so children ? Why don’t they limit the size of their families ? The answer may be that they often have no choice . There are several reasons for this .
非洲和亚洲的很多发展中国家，人 P 增长迅速。原因很简单：这些国家的女人生育率很 高——每个 女人平均有三个到七个孩子。这些女人大部分都很穷，没有足够的食物和资源来照顾家庭。为什么她们 要有这么多孩子呢？为什么她们不限制家庭的大小呢？答案是大多数时候她们 没办法选择。这有很多原因。
One reason is economic . In a traditional agricultural economy , large families are helpful .Having more children means having more workers in the fields and someone to take care of the parents in old age. 1 In an industrial economy, the situation is different. Many children do not help a family ; instead, they are an expense. Thus, industrialization has generally brought down the birth rate. This was the case in Italy, which was industrialized quite recently and rapidly. In the early part of the twentieth century, Italy was a poor, largely agricultural country with a high birth rate. After World War Ⅱ, Italys economy was rapidly modernized and industrialized. By the end of the century, the birth rate had dropped to 1. 3 children per woman, the worlds lowest.
其中之一是经济原因。传统的农业经济中，家庭成员数目多是十分有利的。孩子多意味着田里的劳 动力多且有人给父母养老。在工业经济国家中情况就不同了。多数孩子不帮助家里，而是 增加家庭开销。 因此，工业化极大降低了生育率。这是意大利的一个例子，意大利最近几年工业化发展十分迅速。在20 世纪前叶，意大利是个贫穷的农业国家，有着很高的生育率。第二次世界 大战之后，意大利的现代化和工业化十分迅速。世纪之末其生育率降到世界最低，平均每个女人 1. 3个孩子
However, the economy is not the only important factor that influences birth rate. Saudi Arabia, for example, does not have an agriculture-based economy, and it has one of the highest per capita incomes in the world. Nevertheless, it also has a very high birth rate (7. 0). Mexico and Indonesia, on the other hand, are poor countries, with largely agricultural economies, but they have recently reduced their population growth.
然而经济并不是唯一重要的影响出生率的因素。以沙特阿拉伯为例，那里并没有以农业为基础的经 济，而且是人均收入最高的国家之一。然而还是有很高的生育率(7. 0)。而像墨西哥和印 度尼西亚，主要 是农业经济的穷国，但他们的人口还在不断地下降。
Clearly, other factors are involved. The most important of these is the condition of women. A high birth rate almost always goes together with lack of education and low status for women. 2 This would explain the high birth rate of Saudi Arabia. There, the traditional culture gives women little education or independence and few possibilities outside the home . On the other hand, the improved condition of women in Mexico, Thailand, and Indonesia explains the decline in birth rates in these countries .Their governments have taken measures to provide more education and opportunities for women.
很明显有其他的因素。最重要的就是妇女的状况。高的生育率往往与妇女缺乏教育与社会地位低下 相关。这就能解释沙特阿拉伯的出生率为什么如此之髙。传统的文化使妇女缺乏教育或者 不能独立，并 且在外生存的技能很少。相反，墨西哥、泰国、印度尼西亚的生育率就低。他们的政府给妇女提供更多的教育和机会。
Another key factor in the birth rate is birth control. Women may want to limit their families but have no way to do so. In countries where governments have made birth control easily available and inexpensive, birth rates have gone down. This is the case in Singapore, Sri Lanka, and India, as well as in Indonesia, Thailand, Mexico, and Brazil. In these countries, women have also been provided with health care and help in planning their families.
另一个重要的因素是计划生育。女人们也许想限制家庭的'大小，但是她们没有办法。一些倡导计划 生育的政府为她们提供有效而且不贵的方式，生育率下降。比如新加坡、斯里兰卡、印度 和印度尼西亚、 泰国、墨西哥、巴西。在这些国家妇女被提供健康和计划生育的帮助。
These trends show that an effective program to reduce population growth does not have to depend on better economic conditions. 3 It can be effective if it aims to help women and meet their needs. Only then, in fact, does it have any real chance of success.
这些趋势表明有效的控制人口的方案并不依赖于良好的经济状况。如果是致力于帮助妇女适应她们 的需求那么就是有效的。事实上只有这样，才能有机会取得成功。
词汇：
industrialization n工业化
possibility n可能性，可能发生的事物
effective adj有效的，起作用的，实际的

4. B 本题的问题是：文中提到沙特阿拉伯的例子说明了什么？由第三段开头可知，However, the economy is not the only important factor that influences birth rate. 下面将要介绍其他因素，之后以沙特阿拉伯为例。故正确答案为 B，经济以外影响出生率的因素。
5. In Mexico, Thailand, and Indonesia, the government _______.
A. is not concerned about the status of women
B. has tried to industrialize the country rapidly
C. does not allow women to work outside the home
D. has tried to improve the condition of women
5. D 本题的问题是： 墨西哥、 泰国、 印度尼西亚的政府采取了怎样的措施？从文中第四段后半部分On the other hand, the improved condition of women in Mexico, Thailand, and Indonesia explains the decline in birth rates in these countries. Their governments have taken measures to provide more education and opportunities for women. 可以得出结论。另一方面从第四段开头也可以得出结论。The most important of these is the condition of women. 之后举出这几个国家的例子，从而也可以得出结论。

Ice Cream Taster Has Sweet Job
John Harrison has what must be the most wanted job in the United States. He’s the official taster for Edy’s Grand Ice Cream, one of the nation’s best-selling brands. Harrison’s taste buds are insured for $1 million. ___1___ And when he isn’t doing that, he travels, buying Edy’s in supermarkets all over the country so that he can check for perfect appearance, texture, and flavor.
After I interviewed Harrison, I realized that the life of an ice cream taster isn’t all Cookies ’n Cream — a flavor thathe invented, by the way. No, it’s extremely hard work, which requires discipline and selflessness.
For one thing, he doesn’t swallow on the job. Like a coffee taster, Harrison spits. Using a gold spoon to avoid “off” flavors, he takes a small bite and moves it around in his mouth to introduce it to all 9,000 or so taste buds. ___2___ Then he breathes in gently to bring the aroma up through the back of his nose. Each step helps Harrison evaluate whether the ice cream has a good balance of dairy, sweetness, and added ingredients 一 the three-flavor components of ice cream. Then, even if the ice cream tastes heavenly, he puts it into a trash can. A full stomach makes it, impossible to judge the quality of the flavors.
During the workweek, Harrison told me that he has to make other sacrifices, too: no onions, garlic, or spicy food, and no caffeine. Caffeine will block the taste buds, he says, so his breakfast is a cup of herbal tea. ___3___
Harrison’s family has been in the ice cream business in one way or another1 for four generations, so Harrison has spent his entire life with it2. However, he has never lost his love for its cold, creamy sweetness. ___4___ On these occasions3, he does swallow, and he eats about a quart (0.95 liters) each week. By comparison4, the average person in the United States eats 23.2 quarts (21. 96 liters) of ice cream and other frozen dairy products each year.
Edy’s ice cream is available in dozens of flavors. So what flavor does the best-trained ice-cream taster in the country prefer? Vanilla! In fact, vanilla is the best-selling variety in the United States. ___5___ “It’s a very complex flavor,” Harrison says.
练习：
A However, you should never call it plain vanilla.
B He even orders ice cream in restaurants for dessert.
C Next he smack-smack-smacks his lips to get some air into the sample.
D This is a small price to pay for what he calls the world’s best job.
E In his younger days, he would help out at the ice cream factory his uncle owned.
F He gets to sample 60 ice creams a day at Edy’s headquarters in Oakland, California.
Hurricane Katrina
A hurricane is a fiercely powerful, rotating form of tropical storm that can be 124 to 1,240 miles in diameter. The term hurricane is derived from Hurican, the name of a native American storm god. Hurricanes are typical of a calm central region of low pressure between 12 to 60 miles in diameter, known as the eye. They occur in tropical regions. Over its lifetime, one of these storms can release as much energy as 10,000 nuclear bombs.
The seed for hurricane formation5 is a cluster of thunderstorms over warm tropical waters. Hurricanes can only form and be fed when the sea-surface temperature exceeds 27℃ and the surrounding atmosphere is calm. These requirements are met between June and November in the northern hemisphere.
Under these conditions, large quantities of water evaporate and condense into clouds and rain - releasing heat in the process. It is this heat energy, combined with the rotation of the Earth, that drives a hurricane.
When the warm column of air from the sea surface first begins to rise, it causes an area of low pressure. This in turn creates wind as air is drawn into the area. This spinning wind drags up more moisture-laden air from the sea surface in a process that swells the storm. Cold air falls back to the ocean surface through the eye and on the outside of the storm.
Initially, when wind speeds reach 23 miles per hour, these mild, wet and grey weather systems are known as depressions. Hurricane Katrina formed in this way over the south-eastern Bahamas on 23 August 2005. Katrina has had a devastating impact on the Gulf Coast of the US, leaving a disaster zone of 90,000 square miles in its wake - almost the size of the UK. Thousands have been killed or injured and more than half a million people have been displaced in a humanitarian crisis of a scale not seen in the US since the great depression. The cost of the
damage may top $100 billion.

【答案】CACBD
1、A characteristic of American culture that has become almost a tradition is to respect the self-made man - the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.
This attitude toward manual (体力的) labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously (豪华地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward; furthermore, the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.
1)、From Para. 1, we know that in America _________.
A.people tend to have a high opinion of the self-made man
B.people can always rise to the top through their won efforts

答案：B
3)、The underlined expression “wait on table” in Para. 2 means “_________”。
A.work in a furniture shop

2、It looks like a mobile phone, but the service is much cheaper. It acts like a mobile phone, but only in your own city. Beyond the city walls, it is useless.
"Little Smart", also called "Xiaolingtong", has always been compared to mobile phones. But actually it is more like one of those cordless phones(无绳电话) used around the home. The only difference is that this one reaches much further. It can travel across an entire city.
Cheap costs are the main reason for the success of Little Smart. It costs 25 yuan a month for the line and about 0.1 yuan per minute to use. Whats more, unlike mobile phones, there is no fee for incoming calls.
But Little Smart is not really that smart. Users often complain about its bad service quality. "I couldnt receive a phone call if I was on a bus," said Li, a user in Beijing. "It worked fine when I stood still, but there were breaks in signal when I was moving."
Scientists are trying to make Little Smart more user-friendly. Messaging and Internet access (接入) have been added to the service. And the latest Little Smart handset even has color screen(彩屏).
1)、Little Smart is so popular in China because it looks like a mobile phone.

3、Who will stage the games?
Preparing for the Olympic Games is a huge undertaking (工程). Just like the athletes, the host city spends years getting ready for the event. Before deciding which city will host the Olympic Games, the International Olympic Committee (IOC) has to examine bids from all over the world. Bidding for the games begins about ten years in advance. Without preparing a very strong bid, a city will not win the competition to host the games. Beijing was chosen for the 2008 games from five bidders 一 Osaka, Paris, Toronto and Istanbul.
Why does it take so long to prepare?
Building the infrastructure (基础设施) costs huge amounts of money. Holding the World Cup in 2002 in Japan and South Korea, for example, meant that ten new stadiums had to be built, as well as many hotels and an improved transport system. In Beijing, after winning the bid the government began major construction projects 一 the extension of the underground, the improvement of the airport and the building of new motorways. Each host city must also build an Olympic village for the athletes. By planting trees and creating parks, the city becomes more attractive for tourists.
Why do countries want to host the Olympic Games?
Hosting the games has a major effect on the economy and brings international prestige(声望) to the country. Thousands and thousands of visitors come to the games and the host cities are permanently improved.
1)、Bidding for the Olympic Games usually starts one year before the games are really held.
A.T B.F
答案：B
2)、Beijing was one of the five bidders for the 2008 games.
A.T B.F

4、Taking away a citys rubbish is a big job. Every day trucks come into a city to collect it. Most rubbish is made up of things we cant eat or use. If we kept these things, we would soon have a mountain of rubbish.
In some cities the rubbish is collected and taken outside the city to a dump. Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage(污水，排水)system. The sewage system takes away the used water from toilets, bathtubs and other places.
To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or a school may be built there, and then youd never know that this had once been an old rubbish dump.
In other cities the rubbish is burnt in special places. The fire burns everything except the metal.Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles where they slowly change into something called humus(腐殖质), which looks like black earth. It is rich with the kinds of things that feed plants and help make them grow.
1)、You can most probably read this kind of passage in a telephone book.
A.T B.F
答案：B
2)、The main idea of the passage is to tell people to take useful things out of rubbish.
A.T B.F

三、阅读题：
Thus far, there is little evidence to suggest that technology will reduce inequality; indeed it may only intensify inequality. Technology is costly and it is generally impossible to introduce advances to everyone at the same time. So who gets this access first? As we travel further and further along the electronic frontier through advances such as telecommuting （在家办公） and the Intemet, the poor may be isolated from mainstream society in an "information ghetto （贫民窟） "。
Drawing on a survey, the Census Bureau （国家调查局） estimated that only 6.8 percent of households earning less than $ 10,000 had home computers, compared to 61.7 percent of those with incomes of $ 75,000 or more. This issue goes beyond individual interest or lack of interest in computers.
The technological advances of the present and future may not be equally beneficial to men and women. Many studies have shown that computer games, which serve as an important means of early socialization to computers, typically involve sports or skills associated with the traditional male role. As a result computers camps have become mainly male settings.
Like money, food, and other resources, technology is unevenly distributed within societies and throughout the world. The technology gap is widening rather than narrowing. Although nations are exchanging technical data more freely than before, critical technology transfer is often kept back. The technology exported to developing countries may be poorly suited to the conditions of their economies and workplaces.
11、According to the writer, "information ghetto" is caused by ______.
A.the strict control of information
B.the rapid technological advances
C.the complete isolation of the poor
D.the existence of mainstream society
12、The data the Census Bureau collected indicates that ______.
A.technology has widened the gap between the rich and the poor
B.individual interest in computers might be a significant reason
C.the survey has covered more than enough investigation samples
D.the estimation by the Census Bureau is subject to correction
13、According to the writer, one supposed function of computer games is ______.
A.to divide social roles between boys and girls
B.to build up settings for sports or other male skills
C.to make the public get familiar with the computer
D.to intensify the inequality between men and women
14、It seems that critical technology is often ______.
A.unavailable to the importing countries
B.unavailable to the exporting countries
C.not suitable to the developing countries
D.keeping back the exporting countries economy
15、The writer s attitude towards the development of technology is ______.
A.negative
B.indifferent
C.exciting and praising
D.concerned and critical

第一篇 Why Buy Shade-Grown Coffee?
When people argue about whether coffee is good for health, theyre usually thinking of the health of the coffee drinker. Is it food for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.
Traditionally, coffee bushes were planted under the canopy(树冠)of taller indigenous(土生土长的)trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t any trees. With increased production come increased profits.
Unfortunately, deforesting for coffee production immediately decreases local-wildlife habitat. Native birds nest and hide from predators(捕食者)in the tall trees and migrating birds rest there.
Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.
Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade grown" and "bird friendly." Sure, these varieties might cost a little more. But were paying for the health of the birds, the land, ourselves, and the planet. I think its worth it.
31. What is the main idea of this passage?
A. Farmers are changing the way they grow coffee.
B. Coffee is becoming more expensive to produce.
C. Shade-grow coffee is more expensive than sun-grow coffee.
D. People should buy shade-grown coffee.
32. The function of the word "Traditionally" in Paragraph 2 is to show_____.
A. the positive effects of coffee.
B. a change of coffee growth.
C. something that is the most important.
D. how coffee production used to be.
33.What does increased production of full-sun coffee bring about?
A. More insects.
B. Better quality coffee.
C. Larger farms.
D. Higher profits.
34. How do farmers find more land for growing full-sun coffee?
A. They buy more land from other farmers.
B. They cut down trees.
C. They move to another country.
D. They turn grassland into farmland.
35.The full-sun method may affect the following EXCEPT_____ full sun
A. insects.
B. air.
C. birds
D. humans
答案：31-35.D B D B B
第二篇 More Rural Research is Needed
Agricultural research funding is vital if the world is to feed itself better than it does now. Dr. Tony Fischer, crop scientist, said demand was growing at 2.5% per year but with modern technologies and the development of new ones, the world should be able to stay ahead.
“The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition(营养不良)and poverty.” he said.
Research is needed to solve food production, land degradation(贫瘠化)and environmental problems. Secure local food supplies led to economic growth which is turn, slowed population growth. Dr. Fischer painted a picture of the world’s ability to feed itself in the first 25 years, when the world’s population is expected to rise from 5 X to X billion people. He said that things will probably hold or improve but there’ll still be a lot of hungry people. The biggest concentration of poor and hungry people would be in sub-Saharan Africa and southern Asia in 2020, similar to the current pattern. If there is any change, a slight improvement will be seen in southern Asia, but not in sub-Saharan Africa. The major improvement will be in East Asia, South America and South-East Asia.
The developing world was investing about 0.5%, or $8 billion a year, of its agricultural gross domestic product(GDP)on research and developed world was spending 2.5% of its GDP. Dr. Fischer said more was needed from all countries.
He said crop research could produce technologies that spread across many countries, such as wheat production research having spin-offs(有用的。副产品)for Mexico, China or India.
“Technologies still need to be refined for the local conditions but a lot of the strategic research can have global application, so that money can be used very efficiently.” Dr. Fischer said.
Yields of rice, wheat ad maize(玉米)havegrown impressively in the past 30 years, especially in developing countries. For example, maize production rose from 2 to 8 tonnes per hectare between 1950 and 1995. But technologies driving this growth such as high-yield varieties, fertilizers, and irrigation, were becoming exhausted. “If you want to save the land for non-agricultural activities, for forests and wildlife, you’re going to have to increase yield.” Dr. Fischer said.
36. What is the passage mainly about?
A. Shortage of food supplies.
B. Development of agricultural technologies.
C. Impact of agricultural research.
D. Expectation of population growth.
37. Which of the following statements is true about the world’s agricultural research funding?
A. It is increasing among developed countries.
B. It is decreasing worldwide.
C. Less is demanded from developing countries.
D. Most of it is spent very efficiently.
38. What is the picture of Asia’s food supplies in the first 25 years?
A. Food shortage will not be a problem
B. There will be more hungry people in southern Asia.
C. Population growth will result in more hungry people.
D. There will be fewer hungry people in East Asia.
39. What does Dr. Fischer say about technologies? Dr Fischer
A. They are costly.
B. They have to be improved to meet local needs.
C. Their application is limited.
D. They have to be applied locally.
40. It can be infered from the last paragraph that_____.
A. there is a demand for saving land for non-agricultural activities.
B. crop production is growing faster in developing countries.
C. maize production reached its peak in the 1990s.
D. technologies improving maize production have been well developed.
答案：36-40. C B C B A
第三篇 Dangers await babies with altitude
Women who live in the worlds highest communities tend to give birth to under-weight babies, a new study suggests. These babies may grow into adults with a high risk of heart disease and strokes.
Research has hinted that newborns in mountain communities are lighter than average. But it wasnt clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished — many people who live at high altitudes are relatively poor compared with those living lower down.
To find out more, Dino Giussani and his team at Cambridge University studied the records of 400 births in Bolivia during 1976 and 1998. The babies were born in both rich and poor areas of two cities: La Paz and Santa Cruz. L Paz is the highest city in the world, at 3.65 kilometers above sea level, while Santa Cruz is much lower, at 0.44 kilometers.
Sure enough, Giussani found that the average birthweight of babies in La Paz was significantly lower than in Santa Cruz. This was true in both high and low-income families. Even babies born to poor families in Santa Cruz were heavier on average than babies born to wealthy families in lofty La Paz. "We were very surprised by this result," says Giussani.
The results suggest that babies born at high altitude are deprived of oxygen before birth. "This may trigger the release or suppression of hormones that regulate growth of the unborn child," says Giussani.
His team also found that high-altitude babies tended to have relatively larger heads compared with their bodies. This is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to rest of the body.
Giussani wants to find out if such babies have a higher risk of disease in later life. People born in La Paz might be prone to heart trouble in adulthood, for example. Low birth weight is a risk factor for coronary(冠状的) heart disease. And newborns with a high ratio of head size to body weight are often predisposed to high blood pressure and strokes in later life.
41. What does the new study discover?
A. Babies born to wealthy families are heaver.
B. Women living at high altitude tend to give birth to underweight babies.
C. Newborns in cities are lighter than average.
D. Low-altitude babies have a high risk of heart disease in later life.
42. Giussani and his team are sure that _____.
A. babies born in Lance Paz are on average lighter than in Santa Cruz.
B. people living at high altitudes tend to give birth to underweight babies.
C. the birth weight of babies born to wealthy families is Santa Cruz.
D. mothers in La Paz are commonly under-nourished.
43. It can be inferred from what Giussani says in Paragraph 4 that_____.
A. the finding was unexpected
B. he was very tired.
C. the study took longer than expected.
D. he was surprised to find low-income families in La Paz.
44. The results of the study indicate the reason for the underweight babies is _____.
A. lack of certain nutrition.
B. power of their mother.
C. different family backgrounds.
D. reduction of oxygen levels.
45. It can be learned about form the paragraph that_____.
A. high-altitude babies tend to have high blood pressure in later life.
B. under-weight babies have a shorter life span.
C. babies born to poor families lack hormones before birth.
D. new born wealthy families have larger heads compared with their bodies.

第2部分 阅读判断
Eastern Quakes Can Trigger Big Shakes
In the first week of November 2011,people in central Oklahoma experienced more than two dozen earthquakes. The largest, a magnitude(量)5.6 quake, shook thousands of fans in a college football stadium, caused cracks in a few buildings and scared many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV, you see reports about all sorts of natural disasters. But the most dangerous type of natural disaster, and also the most unpredictable, is the earthquake.
Researchers at the US Geological Survey(USGS)estimate that several million earthquakes occur globally each year. That may sound scary, but people don't feel many of them because they happen in remote and unpopulated regions. Many quakes happen under the ocean, and others have a very small magnitude.
Scientists know about small, remote quakes only because of very sensitive electronic devices called seismometers（地震仪）。 These devices detect and measure the size of ground vibrations（震颤）produced by earthquakes. Altogether, USGS researchers use seismometers to identify and locate about 20000 earthquakes each year.
Although earthquakes can happen anywhere in the world, really big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher and happen, on average, only once each year. Such big ones typically occur along the edges of Earth's tectonic plates（构造板块）。
Thctonic plates are huge pieces of Earth's crust（外壳）， sometimes many kilometers thick. Often, edges of these plates temporarily lock together. When plates push and scrape(擦)past each other earthquakes occur. On average, tectonic plates move very slowly--bout the same speed as your fingernails grow.
But sometimes earthquakes rumble（轰轰作响）through portions of the landscape far from a plate's edges. Although less expected, these "mid-plate" small earthquakes can be stantial damage. Some of the biggest known examples hit the eastern half of the United States two centuries ago. Today, scientists are still puzzling over why the quakes occurred and when similar ones might occur.
16、 Oklahoma is an area often experiencing natural disasters.
A. Right B.Wrong C. Not mentioned
17、 The earthquake is the most unpredictable natural disaster.
A. Right B.Wrong C. Not mentioned
18、 Few earthquakes happen without people's awareness.

20、 Big earthquakes of a magnitude 8 or higher seldom happen far from the edges of tectonic plates.
A. Right B.Wrong C. Not mentioned
21、 Whenever tectonic plates move, earthquakes happen.
A. Right B.Wrong C. Not mentioned
22、 The earthquake that hit the eastern half of the United States two centuries ago is the biggest"mid-plate" one in history.
A. Right B.Wrong C. Not mentioned
16 A 根据第一段倒数第二句：If you watch the news on TV, you see reports about all sorts of natural disasters.（如果你经常看电视的话，你会看到各种各样的关于自然灾害的`报道。）
17 A 根据第一段最后一句：But the most dangerous type of natural disaster, and also the most unpredictable, is the earthquake.
18 B 本题的意思是：几乎所有的地震人们都有感知。根据第二段最后两句，我们得出：很多地震是人们感觉不到的。

Learn about Noble Gases（惰性气体）
1 Have you ever ridden on a balloon? Many tourist spots offer balloon rides in order for people to see the beauty of a place from above. A balloon contains a noble gas called hellum(氦)。 Formerly, balloons contained hydrogen but hydrogen is very flammable and dangerous when uncontrolled. Therefore, people shifted to helium, which is safer. Helium is safe because it has the properties of the noble gases.
2 People once belleved that noble gases couldn't chemically react at all. For this reason, they were called inert gases（惰性气体）。 They were also listed under Group 0 in the old periodic table because scientists believed that the gases have zero valence(价)electrons in their outer shell. This was later proven to be untrue when some noble gas compounds were discovered.
3 The gases are elements, which share similar properties. These properties include being monoatomic, colorless, odorless, being able to conduct electricity, and having low chemical reactivity. Noble gases include Helium, Neon, Argon, Krypton, Xenon and Radon. These are all found in Group 18, in the rightmost column of the periodic table. If you look at the periodic table, you will notice that these elements are the only ones, which do not have a charge. Helium has the lowest molecular（分子的）weight while Radon is the heaviest.
4 Remember that chemical reactions occur because atoms have valence electrons, which are electrons in their outer shell. When the outer shell is "unfilled" or the required number of electrons is not yet complete, the atom is more reactive. Noble gases have a full outer shell, meaning that they have complete electrons in their outer shell. This complete number varies. For instance, the outer shell of Helium has 2 valence electrons while the outer shell of Xenon has 8 electrons. Nowadays, there remains to be a few noble gases because of the low chemical reactivity of these said gases.
5 because of their properties, noble gases have many important applications. They are widely used in medicine and industries. For instance, liquid Helium is used for superconducting magnets（磁体）。 These magnets are very important in physics and medicine. When a doctor suspects that a person's brain has been damaged, he might request for Magnetic Resonance Imaging(MRI)。 MRI allows the doctor to "see" the brain, without operating on the patient.

第一篇
Gross National Happiness
In the last century, new technology improved the lives of many people in many countries. However, one country resisted these changes. High in the Himalayan mountains of Asia, the kingdom of Bhutan remained separate. Its people and Buddhist（佛教）culture had not been affected for almost a thousand years. Bhutan, however, was a poor country. People died at a young age. Most of its people could not read, and they did not know much about the outside world. Then, in 1972, a new ruler named King Jigme Singye Wangchuck decided to help Bhutan to become modern, but without losing its traditions.
King Wangchuck looked at other countries for ideas. He saw that most countries measured their progress by their Gross Natonal Product(GNP)。 The GNP measures products and money. When the number of products sold increases, people say the country is making progress. King Wangchuck had a different idea for Bhutan. He wanted to measure his country's progress by people's happiness. If the people's happiness increased, the king could say that Bhutan was making progress. To decide if people were happier, he created a measure called Gross National Happiness(GNH)。
GNH is based on certain principles that create happiness. People are happier if they have health care, education, and jobs. They are happier when they live in a healthy, protected environment. They are happier when they can keep their traditional culture and customs. Finally, people are happier when they have a good, stable government.
Now these is some evidence of increased GNH in Bhutan. People are healthier and are living longer. More people are educated and employed. Teenty-five percent of the land has become national parks, and the country has almost no pollution. The Bhutanese continue to wear their traditional clothing and follow their ancient Buddhist customs. Bhutan has also become a democracy. In 2008, King Wangchuck gave his power to his son. Although the country still had a king, it held its first democratic elections that year. Bhutan had political parties and political candidates for the first time. Finally, Bhutan has connected to the rest of the world through television and internet.
Bhutan is a symbol for social progress. Many countries are now interested in Bhutan's GNH. These countries are investigating their own ways to measure happiness. They want to create new policies that take care of their people, cultures, and land.
Brazil may be the nest country to use the principles of GNH. Brazilian leaders see the principles of GNH as a source of inspiration. Brazil is a large country with a diverse population. If happiness works as a measure of progress in Brazil, perhaps the rest of the world will follow.
31、 Who was Jigme Singye Wangchuck?
A. A king. B 。 A president. C. A Buddhist priest. D. A general.
32、 Apart from modernizing Bhutan, what else did Wangchuck want to do for Bhutan?
A. To make its population grow.
B. To keep its traditions and customs.
C. To keep it separate from the world.
D. To encourage its people to get rich.
33、 A country shows its progress with GNP by
A. spending more money.
B. spending less money.
C. providing more jobs.
D. selling more products.
34、 According to GNH, people are happier if they
A. have new technology.
B. can change their religion.
C. have a good, stable government.
D. have more money.
35、 Today many countries are
A. using the principles of GNH to measure their progress.
B. working together to develop a common scale to measure GNH.
C. taking both Bhutan and Brazil as symbols for social progress.
D. trying to find their own ways to measure happiness.
31 C 第一段里就提到一位名为King Jigyne Singye Wangchuck的新的统治者，很显然Wangchuck是一位国王。
32 D 第一段的结尾处讲到King Jigme Singye Wangchuck decided to heip Bhutan to become modern, but without losing its traditions，可见这位国王决定要让不丹现代化，但又不失去自己的传统。
33 C 在第二段里可以找到对GNP一个十分简单化的解释：The GNP measures products and money. When the number of products sold increases, people say the country is making progress，也就是说卖出的产品增加了，就说明这个国家在进步。
34 B 第三毁列举了衡量GNH的多个标准，其中包括人民享受医疗保险、受教育、有工作、生态环境健康并受到保护等。最后提到的一个标准便是人民有个好的、稳定的政府。
35 A 答案在第五段里下面这两个句子中可以看到：Many countries are now interested in Bhutan's GNH. "These countries are investigating their own ways to measure happiness.

Archive Gallery: The Best of Bionics（仿生学）
Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes（长颈鹿）， which are otherwise calm and good-natured, sleep only 4.6 hours a day.
We realized a long, long time ago that nature provides the best blueprint（蓝图）for invention. We've borrowed canals from beavers（河狸）and reflectors from cat's eyes. Although the words "bionics" became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives（档案）don't go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes.
To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright's pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore（梧桐） seeds in an effort to apply those same motions, reversed, to a helicopter.
Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic （简单抽象艺术） structure. On the other hand, Barney Connett's fish submarine （潜水艇） actually looks like a fish.
Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers（蚂蚱）-sounds shocking, doesn't it? But imagine how life would change if we could achieve that.
36、 "cats"，"monkeys" and "giraffes" mentioned in paragraph 1 are examples to illustrate
A. they are highly-evolved species as humans.
B. humans can learn animals'skills.
C. they are skillful in different ways.
D. animals have skills that humans do not possess.
37、 Which of the following can be found in the archive gallery?
A. History books.
B. The Wright brothers'sculpture.
C. First practical airplanes built in the late 19th century.
D. Leonardo da vinci's bird-like flying machines.
38、 What happened after the Wright brothers'success?
A. People carried out a systematic study on pigeons.
B. People studied more animals and plants to develop the airplane.
C. People cound fly their airplane for fun.
D. People kept their airplane at a French gallery.
39、 Which of the following in true about the research carried out by the US Army?
A. It has changed our life.
B. It has cost a large sum of money.
C. It has improved the abilities of tanks.
D. It has not succeeded yet.
40、 What does the writer want to tell in the passage?
A. Many inventions get ideas from nature.
B. Some animals possess unique skills.
C. People should protect nature.
D. Bionics is far from perfect.
36 A 根据第一段第一句：。.。but most animals possess skills we can only dream of having.
37 D 根据第二段最后一句。A和B没有提到。C的叙述恰好与原文相反。
38 C 根据第三段最后两句：一个例子是对海鸥的研究，另一个例子是对梧桐树种子的研究。
39 B 最后一段第一句yet to be invented和最后一句中if we could achieve that都说明了该研究还没有成功。A和D显然不对，C则没有提及。

"Life Form Found" on Saturn's Titan
Scientists say they have discovered hints of alien life on the Saturn's moon. The discovery of a sort of life was announced after researchers at the US space agency,NASA,analyzed data from spacecraft Cassini,which pointed to the existence of methane-based form of life on Saturn's biggest moon.
Scientists have reportedly discovered clues showing primitive alien beings are"breathing" in Titan's dense atmosphere filled with hydrogen.
They argue that hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane lakes and rivers. This,they say,points to the existence of some"bugs" consuming the hydrogen at the surface of the moon less than half the size of the Earth.
"We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan,similar to the way we consume oxygen on Earth,"says NASA scientist Chris McKay."If these signs do turn out to be a sign of life,it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth."
To date,scientists have not yet detected this form of life anywhere,though there are liquid-water-based microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan, where temperatures are around 90 Kelvin (minus 290 degrees Farenheit)，a methanebased organism would have to use a substance that is liquid as its medium for living processes, but not water itself. Water is frozen solid on Titan's surface and much too cold to support life as we know it.
Scientists had expected the Sun's interactions with chemicals in the atmosphere to produce a coating of acetylene on Titan's surface. But Cassini detected no acetylene on the surface.
The absence of detectable acetylene on the Titan's surface can very well have a non-biological explanation,said Mark Allen,a principal investigator of the NASA Titan team.
"Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed,"Allen said. "We have a lot of work to do to rule out possible non-biological explanations. It is more likely that a chemical process,without biology,can explain these results."
41 。What do scientists claim to have found about Saturn?
A. Water-based life on it.
B. Methane-based life on its biggest moon.
C. A new moon moving around it.
D. Earthlike life on its biggest moon.
42、 Which of the following statements about Titan is true?
A. It is as large as the Earth.
B. There is acetylene on its surface.
C. Water on it acts as a life supporting medium.
D. Hydrogen consumption is reported to be on it.
43、 The expression "this form of life" in paragraph 5 refer to?
A. Water-based life.
B. oxygen-based life.
C. Methane-based life.
D. Liquid-based microorganisms.
44、 It can be inferred from Mark Allen's address that
A. Scientists are trying to confirm these is life on Titan.
B. Scientists agree that a chemical process is a convincing explanation.
C. Scientists share the opinion that a biological explanation is reasonable.
D. Scientists are arguing over whether there is life on Titan.
45、 Which of the following can replace the title of this passage?
A 。 A different Life Form, a Possibility.
B. Earthlike Living Beings Found on Titan.
C. Finding of One More Moon of Saturn's.
D. Titan, a New Satellite Discovered.
41 D 根据第一段最后一句：。.。data.。.which pointed to the existence of methane（甲烷） -based form of life on Saturn's biggest moon.
42 C 第二、三、四段说明土星上的生命可能靠氢气生存。A根本没有提及，根据第六段最后一句可以看出B正好与事实相反；第五段最后两句指出水不是支撑生命的媒介，所以D是错误的。
43 C 根据上一段最后一句：。.。because it would represent a second form of life independent from water-based life on Earth.这表明A是不对的。根据全文来看，B和D也与本文不符。
44 B 本文最后一段中。.。after all non-biological explanations are addressed，。.。a lot of work to do.。.可以看出，C和D肯定与Mark Allen的话相悖，A没有提到。
45 A 全文都在讨论一种可能性。不能肯定外星人就像地球人，因此B不对。C和D也与原文不符。

Voice Your Opinion: Change Is Needed in Youth Sports
Everywhere you look, you see kids bouncing a basketball or waving a tennis racquet （网球拍）。 And these kids are getting younger and younger. In some countries, children can compete on basketball, baseball, and volleyball teams starting at age nine. (46) And swimming and gymnastics classes begin at age four, to prepare children for competition.
It's true that a few of these kids will develop into highly skilled athletes and may even become members of the national Olympic teams. (47) This emphasis on competition in sports is having serious negative effects.
Children who get involved in competitive sports at a young age often grow tired of their sport. Many parents pressure their kids to choose one sport and devote all their time to it. (48) But 66 percent of the young athletes wanted to play more than one sport-for fun.
Another problem is the pressure imposed by over-competitive parents and coaches. Children are not naturally competitive. In fact, a recent study by Paulo David found that most children don't even understand the idea of competition until they are seven years old. (49)
The third, and biggest, problem for young athletes is the lack of time to do their homework, have fun, be with friends-in short, time to be kids. When they are forced to spend every afternoon at sports practice, they often start to hate their chosen sport. A searchers found that 70 percent of kids who take part in competitive sports before the of twelve quit before they turn eighteen. (50) Excessive competitive away all the enjoyment.
Need to remember the purpose of youth sports - to give kids a chance to have developing strong, healthy bodies.
A.But what about the others, the average kids?
B.The youth soccer organization has teams for children as young as five.
C.A survey found that 79 percent of parents of young athletes wanted their children concentrate on one sport.
D.Very young kids don't know why their parents are pushing them so hard.
E.Sports for children have two important purposes.
F.Many of them completely lose interest in sports.
46 D 注意这个空格前后的句子都是和小孩参加体育竞赛的低龄化有关的，所以这个空格里的句子很有可能还是讲孩子过小就参与到体育竞赛里去。果然，在六个选项中的D就是讲青年足球组织居然有由5岁大的孩子组成的球队。
47 F 前面一句话讲的是这些孩子中可能有部分人会发展成为优秀的运动员，甚至成为国家奥运队的成员，后面一句话在语义上很有可能出现转折，即大部分人却未必如此。选项F句子开头的but恰恰表明了这一期待中的转折。
48 A 空格后面的以but开头的句子提供了很好的启示。那句话说的是66%的小运动员希望参与多种运动项目，所以前面的那句话极有可能说的是和这一句相反的内容，果然，这些孩子父母的想法和他们不同，他们希望自己的孩子专攻一项运动。
49 C 前面讲的是小孩天生并没有竞争性，7罗以前他们都不懂什么是竞争，所以太小的孩子不会理解自己的爸爸妈妈为什么要对他们施加那么大的压力。
50 B 这一段的中心是过早参与到竞技运动中去会使孩子失去兴趣，空格前面的一句说的是在1 2岁前就参与竞技的孩子中有70%在18岁前放弃，接着说“他们中许多人对运动完全失去了兴趣（ Many of them completely lose interest in sports）”就十分自然、合理。
第6部分 完形填空
Climate Change Poses Major Risks for Unprepared Cities
A new examination of urban policies has been carried out recently by Patricia Romero Lankao.She is a sociologist specializing in climate change and 51 development.She warns that many of the world's fast-growing urban areas，especially in developing countries.will likely suffer from the 52 of changing climate.Her work also concludes that most cities are failing to 53 emissions of carbon dioxide and other greenhouse gases.These gases are known to affect the atmosphere.
"Climate change is a deeply local issue and poses profound 54 to the growing cities of the world," says Romero Lankao. "But too few cities are developing effective strategies to protect their residents."
Cities are 55 sources of greenhouse gases.And urban populations are likely to be among those most severely affected by future climate change. Lankao's findings highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term 56 。
The locations and dense construction patterns of cities often place their populations at greater 57 for natural disasters. Potential threats associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat 58 paved cities more than surrounding areas.The impacts of such natural events can be more 59 in an urban environment.For example，a prolonged heat wave can increase existing levels of air pollution，causing widespread health problems.Poorer neighborhoods that may 60 basic facilities such as drinking water or a dependable network of roads，are especially vulnerable to natural disasters.Many residents in poorer countries live in substandard housing 61 access to reliable drinking water，roads and basic services.
Local governments, therefore ，should take measures to 62 their residents."Unfortunately，they tend to move towards rhetoric 63 meaningful responses, Romero Lankao writes, " They don't impose construction standards that could reduce heating and air conditioning 64 。 They don't emphasize mass transit and reduce automobile use. In fact, many local governments are taking a hands-off approach." 65 ， she urges them to change their idle policies and to take strong steps to prevent the harmful effects of climate change on cities.

解析
51、A 本句中的climate change和industrial development有关。
52、D 本句中应是changing climate带来的影响(impact)。
53、A 根据上下文，应是“减少二氧化碳的排放”。
54、B pose a threat to…是固定搭配，意为：给……带来威胁。
55、D 根据句意，所有选项中只有major和sources搭配合适。
56、A 根据上下文，政策干预会带来短期的和长期的效益（ benefit）。
57、C place(put)。.。at risk是固定搭配，意为：把……置于风险之中
58、D heavily paved cities意思是被钢筋、水泥覆盖的城市。
59、B 根据上下文，impact应和serious措配。
60、A 根据本句开头poorer neighborhoods可以断定lack是唯一的选择。
61、B without access to reliable drinking water的意思是不能获得可靠的饮用水。
62、C 根据上下文，政府要保护居民。
63、D 用unfortunately表示转折，rhetoric和meaningful response并列，所以可以判断other than（而不是）为正确答案。
64、A 根据上下文，air conditioning只能和needs搭配。
65、C 上下句是因果关系，Thus（因此）是正确的。
If U.S. software companies don’t pay more attention to quality, they could kiss their business good-bye. Both India and Brazil are developing a world-class software industry. Their weapon is quality and one of their jobs is to attract the top U.S. quality specialists whose voices are not listened to in their country.
Already, of the world’s 12 software houses that have earned the highest rating in the world, seven are in India. That’s largely because they have used new methodologies rejected by American software specialists. For example, for decades, quality specialists, W. Edwards Deming and J. M. Juran had urged U.S. software companies to change their attitudes to quality. But their quality call mainly fell on deaf ears in the U.S. -but not in Japan. By the 1970s and 1980s, Japan was grabbing market share with better, cheaper products. They used Deming’s and Juran’s ideas to bring down the cost of good quality to as little as 5% of total production costs. In U.S. factories, the cost of quality then was 10 times as high: 50%. In software, it still is.
Watts S. Humphrey spent 27 years at IBM heading up software production and then quality assurance. But his advice was seldom paid attention to. He retired from IBM in 1986. In 1987, he worked out a system for assessing and improving software quality. It has proved its value time and again. For example, in 1990 the cost of quality at Raytheon Electronics Systems was almost 60% of total software production costs. It fell to 15% in 1996 and has since further dropped to below 10%.
Like Deming and Juran, Humphrey seems to be wining more praises overseas than at home. The India government and several companies have just founded the Watts Humphrey Software Quality Institute at the Software Technology Park in Chennai, India.
Let’s hope that U.S. lead in software will not be eaten up by its quality problems.
