三、阅读理解
TOPIC: Some people believe that human activities have harmed the Earth, while others
think they have made the Earth a better place. What is your opinion?
Shen You (Nanjing Foreign Language School): I believe this issue should be looked
at from both sides. First of all, obviously, human activities have harmed our
environment. If they had not, why would we be facing so many environmental disasters
and catastrophes (大灾难) today? Earthquakes, sandstorms, tsunamis (海啸), typhoons
(台风), these are all disasters that are occurring more and more often. Our endless
extraction (开采) of natural resources, our careless attitude toward environmental
protection, these are all factors that led to disasters.
Therefore, we human beings should definitely be aware, feel responsible (有责任的)
and even guilty about what we are doing
However, it is unwise to think that human activities have only harmed the environment
rather than benefited it. If that were true, we would all be living on Mars by now.
After all, it is a planet that is not affected by any human activity.
I believe we have done some good to the environment. We have made the environment
a suitable planet for the survival of numerous (无数的) animals, insects and
plants. And by doing that, we are giving the world hope. However, there is still a lot more we can do. For example, we can lead a low-carbon lifestyle. I think by
doing this we will have a better future, and definitely make the world a better place
to live in.
