Dear Sir,
In answer to your advertisement in today's China Daily for the position of secretary to the general manager, I would like to apply for the job.
As you will note from the enclosed resume, I'll graduate from the English Department of Beijing Languages Institute, and have just completed a training class in Secretarial English. During the last summer vocation, I have had experience as a secretary with the Goodluck Foodstuff Co. as listed in the resume.
If these meet your requirement, please grant me an interview. I am free any time from 2:00 p.m. to 5:00 p.m. except Sunday.
Yours faithfully,
