If the students break the rules, they will get punishment, too. On the first day of a new term, 128 students of Morton High School were sent home for wearing the wrong clothes. There are altogether 1,200 students in the school. Usually only 20 students break the school dress rule every day. So the headmaster Theresa Mayerik said it was the worst new term she had ever seen. At Morton High School, students favourite clothing such as baggy(宽大的) trousers, lownecked shirts and tank tops (紧身短背心) are not allowed in classrooms. Some students think they have the right to choose what to wear. But the headmaster doesnt think so. “Id be supportive if half the school was sent home, because 99% will get the message that our school is for education. ”“Freedom” does not mean “free of restriction(约束)”. That is to say there is no total freedom in the world, no matter in the US or in China. ()1. Many Chinese students think that _. A. American students are very free at school B.
