The reasons can be listed as follows. The narrow range of interpersonal communication is one of the main reasons. The high expectation from parents is often said to be another cause. Also, there still exist some improper comparison and evaluation methods in many schools. Its high time that something were done to solve the problem. First, students should communicate more with others. Second, parents should pay more attention to their childrens thoughts. Finally, schools should change their comparison and evaluation methods. In my opinion, all these changes will certainly help students build up their self-confidence as long as they are done properly. I. 用适当的介词填空。用适当的介词填空。 1. Charles was very gentle _ his two kids. 2.
