Dear Sir,
I’m Li Hua from Fujian, When I was reading the advertisement, the aim of this activity impressed me greatly. I think it instructive to learn to live together by living together. It is a good opportunity for the only child like me to learn to share and work together. Therefore I recommend myself to you without hesitation.
As a boy of 17, I am outgoing, good at English and have experience of working well with children aged from 7 to 12. I think it is a kind of win-win activity. For one thing, I can help take care of the children. For another thing, I can improve my English, make more friends, and enrich my life during the summer vacation.
I am looking forward to your early reply.
Sincerely yours,
