Dear my host family:
As you know，we will stay your house for some days，so I’d like to tell you something about myself to help you know about me.
I’m ZhangCheng, a 15-year-old boy who study in BaShu middle school. I love my school, it’s really a good place.
I take part in this kind of summer camp to practice my English and learn more about American culture. I believe it will be an unforgettable experience.
About my hobbies, I like playing basketball very much though I can’t play it so much well. Also I enjoy playing football. Am I energetic?
I hope we will get along well in the coming days.

我是初二暑假去的。。host family人都超级好，美国人又很随性，知道你是外国人所以对你的语言要求相当低的，你连比带划反正让他们明白你的意思就OK。我当时是随身带一个电子词典，遇到不知道怎么说的，就用电子词典的汉译英，输入中文然后会出几个大概意思的英文词然后直接给他们看。。。。。
