    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 1.(need) to practice running as well as doing sit-ups and pull-ups（引体向上）. But have you ever 2.(wonder) what PE classes are like in the US?

In my high school, we are required to take two semesters(学期) of PE 3. (graduate). We play real sports during PE classes, such as basketball and volleyball. There are also some other kinds of American sports that we often play, such as kickball.

I didn’t know the rules of kickball 4. I first came to the US. The teacher allowed me to sit on the sidelines and watch how other students played it in order to let me know the rules.

We also learn some 5.(use) life skills in PE. Last year, I learned how to do CPR（心肺复苏）which is a life-saving skill. We 6.(teach) how to provide 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.

I prefer PE classes in the US to the 7. in China. I think they are more fun and useful.
