Dear Sir/Madam,

I'm very glad to know that our school broadcasting station needed a new member this term. I'm writing to apply the position.

I am Li Hua, a boy from the Senior Two. I have ever been a broadcaster before and last term I won the first prize in the contest of putonghua of our grade. My friends always tell me my voice sounds beautifully. Of course I know clearly become a broadcaster calls for extra devotion, and that more hour after school are necessary for a better performance. Perhaps your high school life will be busier with such a task every day. Besides, I'd like to develop myself and hope to obtain more knowledge after class to make my new school life less colorful

I'm eager for your reply and I'll be more than happy unless you can consider my application. Please contact me by telephone at 5103123 or e-mail at lihua 101 @hotmail. com.

Yours faithfully,

Li Hua
