Dear Tom,
Glad to have received your letter, in which you askme about my plan for the coming summer vacation. Now let me tell you in details.
At first, I will go on a five-day travel to Beijing with my rents. We will visit the Great Wall, Tiananmen Square, the Forbidden City and other famous places
there. After that, I will attend a motor show with my best friend Wang Ming, who is a big fan for roadster. Besides, I' m going on to read an English novel which is by Jane Austin. How about you? What' s your plan for summer vacation?
Looking forward to your reply.
Yours,
Li Hua
