Dear editor，
                         

【考点】提纲作文．

【答案】Dear editor，
   I am Li Hua，a student in Grade Two.I'm writing to offer my opinions about how to keep healthy for the health column to be set up.
   First of all，having a balanced diet is necessary，making us strong and energetic.What's more，enough sleep is of equal importance，because it will allow our body to readjust and gain energy for the next day.Only when we have adequate sleep can we get fully refreshed.In addition，proper exercise is supposed to be done.Taking exercise will build up our strength and get us relaxed.
   Rome was not built in a day.I sincerely hope you will find these proposals helpful.
Yours，
Li Hua
