【考点】提纲作文．

【答案】Dear editor，
     I'm Li Hua，a student from Class One，Senior Three.Recently，our Grade English teacher conducted a sleep time survey for senior three students，and the results are as follows.
Twenty percent of the students slept seven hours；Thirty-five percent of the students slept six hours；Twenty-five percent of the students slept five hours；only five percent of the students sleep eight hours.Among them，boys sleep slightly more than girls.Fifteen percent of the students even sleep less than five hours.What a horrible statistic!
Although we students are under great pressure from study，the lack of sleep does great harm to our bodies.It's a huge burden not only physically but also psychologically.This is a problem that must be solved immediately.
Dear students，we have a long future.On our way to life，we must make sure that we get enough sleep and spend our time wisely.Only in this way can we study and live better.Thank you.
Yours，
Li Hua
