There are lots of rules at Tim's school. He agrees with(赞同) some of them-For example, they can't arrive late; they can't run in the hallways; and they can't eat in class.All these rules are OK because they are reasonable(合理).
But there are some rules Tim doesn't agree with. For example, at his school, they have to wear the uniform and they can't wear jeans. But Tim thinks jeans are good because they are comfortable. At school, they can't listen to music in art class. But most students think listening to music in art class is relaxing.
Tim also has to follow some rules at home. If he wants to watch TV, he has to finish his homework first. And he can't go out with his friends on school nights, that is, from Monday to Friday. He also has to clean his room every week. But he doesn't have to take out the trash. (垃圾)
