Sleep is more important than you may think.As a middle school student,you are usually busy every day.You have to go to school,play with friends,go to sports practice or other activities,and do your homework.By the end of the day,your body needs a good rest.Sleep helps your body get ready for the following day. In China,many students don't get enough sleep.That is not good for their health.So China's Ministry of Education decided to do something.It says primary school students should go to bed before 9:20 pm,middle school students should go to bed before 10:00 pm and the time should be 11:00 pm for high school students. To have a good sleep,you may follow these tips: ●Go to bed at the same time every night. ●Don't have a TV in your room. ●Don 't exercise just before going to bed.Do exercise in the morning or in the afternoon--it helps you sleep better. ●Use your bed just for sleeping--not doing homework,playing games,or talking on the phone.
