Dear Sirs，

　　Having seen your advertisement in XX Evening News of August 6th for a salesman in the Electronic Device Department of your company, I’m very interested in the job and I feel I’m qualified to meet the requirements. Therefore, I’m enclosing a resume together with a reference from my supervisor.

　　As you can see, I once worked in the Electronic Department. So I am familiar with different kinds of electronic devices. I have worked more than once as a salesman in some stores during my previous vacations. Besides, I’m very patient and friendly in nature. I’m confident that I shall be suitable for the kind of work.

　　If you need any further information, I shall be very pleased to supply it. (I’ll be very grateful if you can grant me with an interview.) Looking forward to hearing from you soon.

　　Yours faithfully,

　　YJBYS
