Dear manager, I writting to apply the job which I saw from the newspaper yesteday. I would like to work in your company as a typist. Well, I'm positive and ambitious and I have 5 years experience and I think I'm fit the job. If I can be employed , I will spare no effort to work and devote myself in working. Thanks for reading my letter and I hope I can hear from you! Yours XXXX注意,yours和人名要写右下角。spare no effort to do sth就是努力做某事的意思。
