In American
schools, instead of the teachers going to different rooms, students have their
own class schedules (课程表) and go to
different classrooms. When a student is away from school, they must have an
explanation for being away along with the signature(签名) of a parent. The signed paper is then handed in
to the school office. High school drop outs and students being expelled (除名) are not that uncommon in the States. High
absences without excuses are one of the reasons why students are expelled from
school. American students also enjoy a number of activities out of school like
cheerleading (拉拉队), student government and a host of
different sports.
