暑假补课 

In my opinion, it's not a good idea to attend enrichment classes during the summer vacation. Summer vacation is supposed to be a time for students to have a break between terms of hard work. Without a thorough relax, how can we refresh ourselves? Besides, surfing the internet, visiting museums or reading novels are also ways of learning, which are more interesting to us. 

学习压力 

Nowadays; students are under great pressure, which mainly comes from their school work as well as peers relationship.

Since the competing for better academic work and future is getting fiercer and fiercer, students feel more and more pressure. Meanwhile, learning to get along with schoolmates and other people, including parents, calls for a lot of efforts from them, so they need someway to let the pressure out. 

First of all, one of the effective ways is to communicate their trouble to teachers and classmates so as to get help from them. In addition, students are not supposed to think about exams all the time, which only makes them more stressed out. Instead, they should think about the progress they have made in study, which will surely increase their own confidence. Last but not the least, It is advisable to do more exercise in their spare time to relieve stress, because sports will also help them sleep better at night.
