2017年11月的英语四级口语考试即将到来，那么这一次英语四级口语考试有可能考到什么话题呢?在这里文都教育的英语老师为大家提供下面这一预测话题：共享单车。大家都知道，共享单车是近年来社会上的热点话题。自从有了共享单车，人们的出行方便了很多，甚至大家认为共享单车的流行对空气质量的好转也起到了不小的作用。然而，它的出现随之也带来一些问题：车辆被人损坏、乱停乱放等现象屡见不鲜。

　　下面小编就此话题为宝宝们提供以下一组参考对话：

　　A: What do you think of bike-sharing?

　　B: Well, I think it is a great invention.

　　A: Why?

　　B: First, it gives us great convenience. When the traffic is too heavy, it is wiser to ride a bike than to drive a car. Second, with an increasing number of people riding bikes, the quality of air becomes better.

　　A: Definitely! However, there are also some problems coming with it. You know, some riders do not put them in proper places after riding. For example, some people put them into parking spaces which are for cars only.

　　B: You are right. That must make car owners unhappy.

　　A: What’s more, there are some people who viciously damage the bikes.

　　B: Yes, I can see the saddles of some bikes are stolen. I think public moral consciousness should be strengthened.

　　A: I can’t agree more.
