帮我看看这封英文信有什么纰漏
Dear Sir/Madam,
This is not an application letter.
As a graduate student in Tianjin university,majored in Information Management.I'm interested in your offered position for IS Management Trainee for graduates.But I still don't quite understand what "Information Service management" means.
I mean,I've read the page "day in the life" on your website.It shows that you trainee need to take on responsibility and to perform across various roles.But what professional skills should they have?
I learned some basic knowledge about database and operation system,and I can do some programming job as well.I wonder how much possibility I have to work with the best.
I would be appreciated for your reply.
yours truly

答案

There too many mistakes in this letter.
And I advise you study something about letter style.
And it's not polite
