Knowledge and Diploma
It is generally believed that a high diploma guarantees a
promising future. Some people identify high diplomas with profound knowledge and exceptional competence. Companies also tend to emphasize the academic achievement of a job candidate. Like it or not, there does exist a social reality – the higher diplomas one gets, the more popular he becomes. On the contrary, other people claim that a high diploma doesn’t automatically translate into knowledge. A diploma, in their eyes, is only the acknowledgment of one’s educational experience rather than a guarantee of one’s ability. Therefore, we can never measure the depth of one’s knowledge by the grade of one’s diploma. Besides, many knowledgeable people don’t have a high diploma. Take Bill Gates for example. His dropping out of college cannot deny the fact that he is one of the world’s most learned men.
So I must say no one should ever equate a diploma with knowledge,
because a diploma is nothing but a proof of a short-term study while genuine knowledge needs one’s lifelong devotion.
Doctors are often confronted such a choice: to lie or not to lie to their patient. Studies show that they often believe it is reasonable to lie for the patients own sake. Most doctors believe that the seriously ill do not want to know the truth about their condition, and if they tell them the truth, they may lose their hope. Because of such a belief, many doctors may tell “white lies” to their patients. But now facts are proving that these doctors are wrong. Actually, an overwhelming majority of patients do want to know the truth. We are also learning that truthful information can help patients deal with their disease if we tell it in a proper way. Lies cannot help the patients. Besides, they invade their autonomy and make them unable to make sound decisions. Lies also do harm to those who tell them, their colleagues and the entire medical profession. Therefore, we need to debate this issue openly and put an end to professional deception.
The Advantages and Disadvantages of Living in the 21st century(生活在21世纪的。优缺点)
Living in the 21st century offers certain advantages,such as a higher standard of living, but it also has some disadvantages, such as a polluted environment.
To begin with, most people now have more money for less hard work. They earn higher salaries than before and enjoy better social security, such as social welfare for laid-off workers and disability insurance.
Secondly, because of the advance in medical technology which leads to better medical care and treatment, people’s life expectancy is longer. Moreover, most people now can afford to buy foods of high nutrition and enjoy their leisure time.
Thirdly, modern conveniences such as radio, TV, internet, various vehicles and labour-saving machines in the home, all greatly facilitate human communication, transportation and housework as well.
Nevertheless, living in the 21st century also has its disadvantages. The most serious one is the increasingly polluted environment; air is filled with smog and water is contaminated by iehemicals from factories.Another main disadvantage is the personalization of human relattonships which mostly result from people’s ever-increasing contact with machines and numbers. Still one more disadvantage is the weakening of spiritual values. An undeniable fact is that a large number of people are solely interested in materialistic culture,while neglecting spiritual civilization. Limited by space, we have to skip the examples.
In conclusion, although the 21st century has indeed given us a lot of advantages, it may not have made us wiser, because it has also made our earth dirtier, our people less humane, and our spirituali iife poorer, We shpuld continue to enjoy the benefits of technological advancement,however, we must
make a concerted effort to preserve our natural environment for future generations. Moreover, we should take the time now to make our lives more meaningful in anihcreasingly impersonal, computerized world.
When asked about their opinion of career and family, people always respond differently. Some people think it more important to pursue their career, while there are always other people who argue that family should be the number one in ones life.
It goes without any question毫无疑问that career plays a key role in our life. In the very first place, career can give us an aim to live on. Without career, much of our living time will be certainly wasted. Whats more, career can provide us with a means to live on. Most of the people
earn their income from a job. On the other hand, family is also an indispensable不可或缺的part of life, as many people will admit. Family is always regarded as a place where we can escape from troubles in life. In addition, we can obtain a sense of belonging to归属感from family. Without it,
anyone will feel lonely and desperate绝望的In my opinion, career and family are not contradictory to each other. Rather, they can enhance each other so that ones life can become better and better. Therefore, its not a choice between right and wrong, but one between ideal and practical.
ife gets noisier every day and very few people can be free from noise:of some sort or another. it doesnt matter where you live in the middle of a modern city, or a faraway village the chances are that youll be disturbed by jet airplanes, transistor radios, oil-powered engines, etc. we seem to be getting used to noise, too.
some people feel quite lonely without background music while theyre working. scientific tests have shown that total silence can be a very frightening eperience for a human being. however, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums.
the noise level in some discos is far above the usual safety level for heavy industrial areas.
one recent report about noise and concentration suggested that although lots of people say that noise disturbs their concentration, what really influences their ability to concerttrate is a change in the level of noise. it goes on to say that a background noise which doesnt change too much (music, for
eample) may even help people to concentrate.
