It is indeed difficult to live without a mobile phone as it helps us in day to day activities. I cannot live without a mobile phone. Today's generation uses mobile phones for chatting, surfing and playing games. They don't use the mobile phone for the real purpose. I admit that living wothout a mobile phone is extremely difficult but I can live without addicting apps like Facebook, Twitter etc. The iPhone is a gadget that is encouraging to use social apps and addicting games. These gadgets though facilitate our work but are making us their slaves. For example, if a person's iPhone is not working properly, he will be filled with anger. As new technology is creating new gadgets, so are people raising new demands. They also hamper academics. Buy a mobile phone but use it for something productive.
生活中没有手机是很困难的，因为它能帮助我们进行日常生活，没有手机我无法生存。我们这一代人使用手机来聊天、冲浪和玩游戏。他们不是为了真正的目的而使用手机。我承认用离开手机生活是非常困难的，但是我可以不用像Facebook、Twitter等上瘾的应用程序来生活。iPhone是一个鼓励使用社交应用程序和上瘾游戏的小工具。这些小工具虽然促进了我们的工作，却使我们成为奴隶。例如，如果一个人的iPhone工作不正常，他会充满愤怒。随着新技术正在创造新的玩意儿，人们也提出了新的要求。他们也阻碍了学术界的发展。买一部手机，但要用它来生产。
According to a recent survey, in the last few years, quite a number of young people have chosen to quit their demanding but highly-paid jobs. Although they may have their own respective reasons, I dont think their decisions are wise in reality.
根据最近的一份调查，在最近这些年里，许多年轻人选择了辞退他们需要花很多心血但是薪水很高的工作。虽然他们可能有各自的原因，但是我认为他们的决定其实是不明智的。
Its true the case is not unique. Some people choose to do something less competitive so that they can lead a comfortable, easy life that a highly-paid job cannot obtain. They are afraid that the stresses and strains of work will rob them of joy and happiness and do them harm both physically and mentally. In fact, however, stress isnt the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and challenge, and to give significance to an idle life. People under stress are likely to express their full range of potential and to realize goal of a human life.
这种现象真的不罕见。有些人选择去做一些竞争小一点儿的事情，这样他们就能生活得舒适、轻松，而高薪工作者是不会得到这种生活的`。他们害怕工作的压力和束缚会把他们的快乐和幸福抢去了，而且在身心上都会对他们造成危害。然而，事实上有压力不是人们常常认为的那样是件坏事。一定量的压力对于提供动力和挑战来说至关重要，而且能给闲散的生活带来意义。压力之下的人们有可能会充分发挥他们的潜力，并且实现人生的目标。
Stress is a natural part of everyday life and there is no way to avoid it. What we can do is to learn to deal with it rather than to escape from it.
压力是日常生活中很自然的一部分，无法避免。我们能做的就是学习处理压力，而不是逃避它。
With the steady growth of people’s living standard, I’m mournful to see that more and more species is on the way to extinction, together with the rise of people’s illegal hunting in the last four decades.
伴随着我国人民生活水平的稳步提高，我却很悲伤地看到越来越多的生物物种濒临灭绝和过去四十年间人们非法捕猎的上升。
From the result of a recent survey, we can learn that the frequency of illegal hunting has increased rapidly since the market of animal product is hot. As a consequence, there are nearly 40 kinds of animals dying out each year, compared with less than five kinds in 1963. This will exert negative influence on our ecosystem and diversity of creatures. In this way, a great number of animals may not be seen by our descendants, even by ourselves.
从最近的一项调查中我们可以得知，由于动物产品市场的火爆，非法狩猎的频率正在飞速的上升。因此，现在每年都有将近40种动物灭绝，而这一数据在1963年只有5种。这对我们的生态系统和物种多样性都是非常不利的。如果按照这样发展下去，我们的子孙后代也许就看不到许多的动物了，甚至我们自己也看不到了。
The statistics lead me to convince that illegal hunting is closely bound with the extinction of species. From my point of view, any government which is blind to this issue will pay a heavy cost. Therefore, strong measures should be taken to prevent people from hunting illegally and relevant laws should be passed immediately.
这些数据让我深信非法狩猎与物种的灭绝有着很大多的关系。依我看来，哪个政府对这个问题视而不见，那么他们将会付出惨重的代价。因此，防止人们非法狩猎的强有力的措施必须被执行。
It’ high time that we should attach great importance to the balance of our ecosystem. Let’s take action right now!
现在真的是我们重视我们生态系统平衡的时候了。让我们从现在开始行动吧！
