85. the→a。冠词的错误。这里表示“一个更好的地方”，用a better place而不是“那个更好的地方”；注意后面的place to live是正确的，可以将掉尾介词in省略。

书面表达范文：

   There’s a lot of talk in my class about whether the senior 3 students should spare the time to take part in the winter long run program. 60% of the students think it a good idea, which can require us to take exercise every day. Besides running, we can do many sports such as morning exercises, playing ping-pong ball and playing basketball, but it shouldn’t take up too much time. Exercise builds one’s body and reduces diseases. Sports let their brains have a rest so that their revision will be more effective.

   On the other hand, 30% believe taking exercise is a waste of time and tiring. After having sports, they are much too excited for a long time to pay attention to their lessons. It’s also possible to be hurt in sports.

   As far as I’m concerned, I think it necessary for us to take some exercise. After some exercise, we can feel more refreshed and relaxed, which can help us learn better.
