书面表达 假如你是李明，你的美国笔友Bill来信询问你的暑假计划。请你根据以下内容给他回一

Dear Bill,
How are you doing? You want to know my plan for this summer, well, here it is.
First, I am going to the countryside to visit my grandparents and I'm going to help them with the farmwork and the housework. After that, I will travel to some places of interest to enlarge my knowledge. At the rest time of the vacation, I am going to learn some senior high school subjects so that I will do better in the new term.
What do you think of my plan? How about yours?
Best wishes!
Yours,
Ming Lee
