问题     Our environment is getting worse and worse with the increase of the world population, which affects the environment in two ways. Firstly, the limited energy resources will be used up much faster. Secondly, the increasing population creates more pollution, another severe problem that needs to be solved. Both problems are long-term ones because actions taken now show their results slowly over many years. They are also urgent because delays in action can lead to great suffering and social problems. The question seems to be difficult to handle for most people. However, a person can be a protector of environment in everyday life if he takes actions to save the environment right now. With the development of technology, cars make transportation easier and quicker than before, but we can’t ignore the disadvantages brought to us by more and more cars in use. For example, we are consuming  gasoline(汽油),which is a non-renewable(无法再生的)resource, and will soon be gone. Moreover, the exhausted gas from cars pollutes our air, and our health is therefore threatened by air pollution, which has a big potential effect on our daily life.
    So we can consider walking, taking buses, carpooling (合用汽车), instead of driving ears alone. This seems to be a very slow process that can’t be so effective if it’s taken by a single person. But when more and more people become aware of the importance and positively take it as their personal responsibilities. The condition of the air will be improved to a great extent.  
The author’s main purpose in writing this passage is most probably to _______.
选项 A、complain about people’s slow actions to protect the environment
B、advise people to take actions to protect the environment
C、show himself to be an active environment protector
D、point out the bad effects of technologies in protecting environment
答案B
解析 推断题。本题问作者写这篇文章的主要目的可能是什么。整篇文章提到环境问题和人之间的关系，尤其是最后一段讲到每个人都行动起来对于环境问题的影响将很大，很明显是建议大家都采取行动保护环境。故B选项为正确答案。
