假设你是明启中学高三学生李华。为接待来自英国伙伴校的交流生，校学生会正招募寄宿家庭。你非常希望加入，但发现招募海报提供的信息比较有限。因此，你决定致信校学生会，内容包括：

1. 说明希望成为寄宿家庭的原因；

2. 提出想要进一步了解的信息，并表达对该活动的期待。

参考范文：

Dear Student Union,

I’m Li Hua, a Senior 3 student from Mingqi High School. I’m writing to express my strong desire to be a host family for the exchange students from our U.K. partner school.

The main reason why I’m eager to join is that I’m extremely interested in British culture. I believe hosting them will offer me a precious chance to learn more about it directly. Moreover, I hope to make friends with these students, which will broaden my horizons.

Yet, the information on the recruitment poster is rather limited. I’d like to know whether there are any specific cultural-related activities we need to organize during their stay, and what kind of daily support is required. I sincerely hope this exchange activity will be a great success and look forward to your reply.

Yours sincerely,

Li Hua
