請先閱讀一位母親的來信：
     I am really worried about my daughter, Judy. She always thinks she is too fat. She eats only a little rice
and some vegetables. And she eats no fish, beef or pork. "Cake" and "dessert" are taboo words (忌諱語).
The problem is that she is not fat at all. In fact, the doctor says she is thin and unhealthy. But she still believes
being thinner will make her pretty. I am afraid that she will be sick before she becomes only "prettier". Could
you give some advice to ray daughter?
     根據(jù)這位母親的要求，請以Wang Lei的名義給寫信提一些建議。詞數(shù)在60-80左右。
     提示詞：均衡的飲食balanced diet；依我的觀點in my opinion；必要的necessary；總而言之in a word
Dear Judy, 
                                                                                                                                                           
                                                                                                                                                           
                                                                                                                                                           
Good luck! 
                                                                                                                                             Yours
