Dear Sir/Madam，

I'd like to apply for the post of assistant which was advertised in the newspaper.I found this position quite appealing to me.

I've just graduated from high school.Luckily I'm good at English and I can speak English fluently.In addition，I have previous experience.During my stay in middle school.I used to be a volunteer and looked after the old people in a nursing home on weekends.

In short I believe my experience and fluent oral English will be a great help for me in doing the work.I'm available for interview at any time.It would be appreciated if I can get your offer.

Yours Sincerely，

Li Hua
