     In the United States, headmasters and teachers discipline (惩罚) students in several ways. The teacher often

writes to or calls the students' parents. Sometimes students have to stay at school for one hour. If a student

behaves very badly, the headmaster can stop the student having classes. The student can't come to school for

one, two or three days. Mr. Lazarus, the headmaster of a middle school in Ohio, did not like to do so. When he

didn't let the students come to school, they were happy."A three-day holiday!" they thought.

     One day, a boy was in Mr. Lazarus' office. The boy was not behaving well in class. Mr. Lazarus telephoned

the boy's parents. "If you come to school with your son, I won't stop him having classes," he said. The boy's

father came to school and went with his son to every class. Other students looked at the boy and his father. The

boy was embarrassed. After that he behaved better. And, of course, other students behaved better, too. 

     Now headmasters all over the USA are trying Mr. Lazarus's idea. They too, think that students behave better

when parents come to school.
