【答案解析】
Dear Mr. J. Malloy,
I saw your job advertisement in a newspaper. I think the job is suitable for me, so I write to apply for the job.
My name is Wang Lin, and I"m a college student right now. My major is International Communication, which includes many Chinese courses. So I think I must be qualified for teaching the kids Chinese. I have a lot of experience in teaching kids, both in Chinese and in English. I"m totally free at weekends, so there will be no problem to teach at weekends. I have paid attention to the salary you could offer, and I think it is reasonable.
I"m looking forward to your reply. Thanks for your attention.
Yours sincerely,
Wang Lin
