Senior high school entrance examination( 中考 ) is coming. Discuss what pressure( 压力 )students are facing and how they solve it. Pressure is a serious problem in today’s world. Students in our class are under too much pressure.________________________________________________________________________________________________________________________________

Pressure is a serious problem in today’s world. Students in our class are under too much pressure. Some students can’t get on well with their class-mates, while others may worry about their exams.

Actually, students don’t need to give up their hobbies. During this special time it is a good way for students to relax for some time and they will find it is much easier to do further review.

Senior high school entrance examination is coming. To get high marks, students have to finish a lot of homework every day. And they are sent to all kinds of training classes at weekends,so they don’t have enough time to do their hobbies or sleep.

Besides, to ask parents or teachers for help is another way for students to reduce pressure.They may teach the students which to do first and understand their pressure. To be relaxed can help students do well in the coming exams. So less pressure, better school life!

Homework 1. To revise infinitive.2. To review the phrases in Unit3
