　　Dear Alice,

　　I'm happy to know that you have a three-day vacation I think you should go to the dentist on the first day. If you have a toothache, you can't do other things'happily. On the second day, you can do your homework at home. After studying for a Iong time,you may feel tired. In my opinion, you can go to the cinema on the last day. Watching movies is a good way for you to relax. I hope you'll have a nice vacation.

　　Yours,

　　Liu Jie
