Our school has school rules, and our class also has class rules. We can’t have breakfast in the classroom. Our teacher says we will make our books become dirty if we eat in classroom. Then it becomes the class rules in my class. If anyone breaks this rule, he will be punished. So no one in my class dare¹ to have breakfast in the classroom.

我们学校有校规，而且我们班也有班规。我们不可以在教室里面吃早餐。我们老师说如果我们在教室里面吃早餐的话我们会把书给弄脏的。之后这就成了我们的班规了。任何人违反班规都会受到惩罚。所以在我班上没有一个人敢在教室吃早餐。
