Dear Personal Manager.
I was excited to see your advertisement for employing the summer internship program on your homepage. This is exactly the type of the program that I have been looking for, and I am sure that I could successfully contribute to your company's success. So I am applying to your summer internship program for the position of sales which I have an interest.
As the enclosed resume shows, the courses I took at university include
Business and Economics, and the practical education taught me important skills
in computer using and I had many experiences related to the people.
