Do you want to know PE classes in other countries? In China, students must have PE tests both in middle school and high school. To get good grades on the PE tests, Chinese students will need to run and do sit-ups and pull-ups（引体向上）. However, this is not the way that PE classes work in US high schools.

In US high school, we must take two semesters（学期）of PE. We play real sports during PE classes, such as basketball and volleyball. There are also kickball and dodgeball（躲避球） and some other special American sports. I didn’t know the rules of kickball and dodgeball when I first came to the US. The teacher let me sit on the sidelines and watch how other students played it in order to let me know the rules.

We also learn some useful life skills in PE. Last year, I learned how to do CPR（心肺复苏）. We also learned how to provide first aid（急救）to someone. These skills are a large part of the final grade for the PE class in my high school. We also learn self-defense (自卫) in PE classes, such as tae kwon do（跆拳道）, karate（空手道）skills and Chinese kung fu. It is helpful.

I prefer PE classes in the US to the ones in China. I think they are more fun and useful. What do you think?
