假如你是Mary的好朋友，她在生活中遇到了一些问题，并写了一封信向你求助，请你给她回一封信，回信因涉及到来信的每一个问题，词数80左右。
Dear  Kathy,
I have some problems and I need your help.
I was good at English in the past, but now I am in Grade 3 and I find English is getting more and more difficult. Now I am facing a big test. How should I study for the English test?
Another problem is that now I am not allowed to watch TV. My mother said It was a waste of time, but I don’t think so. I think It’s a good way to have a rest. How can I solve this problem?
The last one is that I used to be thin, but now I am getting fatter and fatter. I am afraid to see my old friends, and I am very sad.
I know you always come up with good ideas. Could you help me deal with these problems?
Yours.
Mary
