请先阅读一位母亲的来信：

     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 (忌讳语).

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?
