5Ⅰ. Complete Mike's letter to Jack using can, have to / must, or can't / mustn't.
Hi, Jack!
Thank you for your letter. Do you want to know about my life here? I am not very happy. I have a lot of rules at school and at home. For school rules, I 1. wear my uniform. I 2. arrive late for class. I 3. eat snacks in the classroom, either. And teachers often say, "You 4. fight with others. You 5. be kind to everyone." For family rules, my parents are very strict with me. I 6. play computer games every day. I 7. only play for thirty minutes at weekends. I 8. hang out with friends at night. I 9. clean my bedroom every day. When it is time to have dinner, I 10. stop watching TV. I never have fun. What can I do?
Write to me soon. Best wishes!
Mike

Ⅱ. Choose a proper sentence for each paragraph from the box and then answer the questions.
Hello! I'm Peter, a student from Guangdong. This year our school has swimming lessons and asks all the students to take them. Here are some rules we have to know when we take a swimming class.
1. The swimming pool in our school is very big, so we can't swim in it by ourselves. We must have a teacher with us every time we go to swim in the pool. I think this rule is good for us.
No food in the pool! We must know that the pool is for taking our lessons. 2. So we can't bring food there. We can eat before or after we have the swimming classes.
Don't fight in the pool! We can play in the pool, but we can't fight there. This is very important. 3. And it's also dangerous to fight in the pool.
4. It will be very dangerous if we're ill in the swimming pool. So when we don't feel well, we must ask the teachers for help in time.
Don't run! Around the swimming pool, the floor will be wet(湿的). 5. So parents must tell their children not to do that.
