Dear Sir or Madam，

After my graduation from college this fall，I am desirous of securing a position that will offer me opportunity in the field of international trading.Knowing something of the scope and enterprise of your huge department，I thought maybe you would keep me in mind for a possible opening.

I majored in Import＆Export Trading.My English scores were always on the top three of my class of sixty.I have learned to operate computer and I can type either in English or in Chinese.

Although I have had no business experience，I am willing to work hard and learn.

Should you entertain my application favorably，I would spare no trouble acquit myself to your satisfaction.

Yours sincerely，
