参考例文：
Dear James，
Nice to hear from you again. As you know， this summer vacation，at the end of July，2005，we winners of NEPC will go to a four-day English Summer Camp in Dalian. Some English teachers from China， the USA， England and Australia will join us. In the camp， we will have some English speaking competition， watch some wonderful performances given by the students and visit some places of interest in Dalian. Besides，we will exchange our English learning experience and talk about our colorful school life in English. I think this summer camp will greatly improve my spoken English and I will make some new friends there. I do hope you will come and join us.
Best wishes！
Yours truly，
Li Hua
