Dear Mr Smith,
I am pleased to have been given the opportunity to be your assistant, but the fact that I am president of the Students’ Union and the English Club means I don’t have enough time to do the job well. Therefore, I recommend my classmate Li Ming to be your assistant instead.
Li Ming is an excellent choice for the position. He is a very good student and has a good command of English. In his spare time, he often organizes various activities in our school. Furthermore, he is honest, kind and easygoing, and he has a great interest in this position. If accepted, he will try his best to do the job.
I am looking forward to your reply.
Yours sincerrely,
LiHua
