2017托福口语练习：环境类话题

　　思路

　　爱护环境，人人有责。虽然，我们平时会聊到环境类的话题。但是，考试时，我们应该怎样顺利地展开这类话题呢?

　　在这种情况下，我们就应该结合自身的经历来展开话题。这样话题不但容易展开，而且也可以加入更多的细节，比如，可以说自己家乡的环境;比如，可以说学习和工作的城市的环境;比如，可以说自己对环保做出的努力。同时，在内容方面也可以更加自由地发挥了。

　　有了这样的思路，我们来看看一篇示范的回答是如何做到这一点的。

　　【话题】What can we do to reduce air pollution? Give examples and details in you answer.

　　托福口语范文

　　I think the following should be done to reduce air pollution. First, we should drive less and use public transportation like buses and subways when we can. It’s such a waste of energy and space to drive when there are only one or two people in the car. Buses and subways on the other hand can move dozens even hundreds of people. Second, I think we should plant more trees. Trees and other plants produce oxygen we breathe. We don’t have enough of them since cities are filled with concrete buildings these days. Trees also make our cities more beautiful, so I think the more trees we plant, the better environment we have.
