Dear tom,
I'm happy to accept your letter .Now I'll tell you about my plan to my summer vacation.
My summer vacation will last for two months.I would go on a guided tour around our capital Beijing,there I can visit some places of interest .I will either tour the campus of Tsinghua University .Then I can spend four weeks take a summer course,hoping they will help me improve my future studies .After that,I'll stay at the home to relax myself.Because I think I will have a busily and colorful summer vacation.what about your plan for holiday
Yours,
Li Hua
