b．文中不能出現(xiàn)真實的校名和人名等。
要點：
（1）為什么要寫這封信。
（2）禁止在自習課上進行的行為（聊天，看課外書，問同學問題……）并解釋原因。
（3）如何利用好自習課的亮點建議。

【答案】Dear classmates，
We have several self-study classes at school.I think it is very necessary.First of all students don't have to go to after- school classes.This can help parents save a lot of money.Second，students can learn better in school because their teachers are around them.Today，I want to tell you some rules of self-study class.I hope you can pay attention to them.Teachers are not allowed to chat in self-study class because our class should be quiet.Reading extra-curricular books is also not allowed because there are a lot of homework to do.And we are not allowed to ask students questions.We should finish our homework by ourselves first.
Students can learn new knowledge by themselves or review what we have learned.When they don't understand，we can always ask the teacher for help.In addition，studying in the classroom can help the students to improve good learning habits.
