Dear Tom,
Thanks for your letter! How are you these days in USA?
Right now, I am about to finish my senior middle school and go to college. You know, I'm facing an exam that will affect my future. It is called 'Gaokao' in China. I have only a few months to prepare for it. Four courses are going to be test such as Chinese, English, Maths and comprehensive course. I am working hard for them: I get up at 7 AM and start reading English and memorizing phases. After graduating from senior middle school, it is summer holiday. I'd like to go visit you in America, I hope we can have a very good time there. Thanks!
Yours,
Li Hua
