    Do you know what PE class are like in other countries? In China, PE tests are required to graduate from both middle school and high school. To get good grades on the PE tests, Chinese students will need to practice running as well as doing sit-ups and pull-ups(引体向上). However, this is not the way that PE classes work in US high schools.

In my high school, we are required to take semesters of PE to graduate. We play real sports during PE class, such as basketball and volleyball. There are also some other typical American sports that we often play, such as kickball and dodgeball(躲避球).

I didn’t know the rules of kickballs and dodgeball when I first came to the US. The teacher asked me to sit on the sidelines and watch how other students played it in order to let me figure out the rules.

We also learn some useful life skills in PE. Last year, I learned how to do CPR(心肺复苏), which is a life-saving skill. We were also taught how to give first aid to someone who is choking(窒息). These skills are a large part of the final grade for the PE class in my high school. Self-defense(自卫)is taught in PE class as sell. This includes some tae known do(跆拳道)and karate(空手道)skills, as well as Chinese kung fu. It is practical.

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