假如你是红星中学学生会主席李明，根据学校安排，你给即将到你校任教的外籍教师Jack推荐一名学生助手（assistant）

Dear Jack,

I’m Li Ming, Chairman of the students’ Union of Hongxing Middle School. It’s great to hear that you are going to teach in our school next semester/term.

I was asked to write to you to recommend Liu Jia, a Senior 3 student of 18, to be your assistant. Liu Jia is a friendly, active and optimistic girl. She is also a smart girl who can use the computer skillfully and has a gift for communicating with others. What’s more, she is one of the top ten students in our school, and her spoken English is extremely excellent. I’m sure she can be helpful in your work and life in China.

If you have any questions about it, please contact me.

I’m looking forward to your coming.

Yours，

Li Ming
