五、Dear all,
I'd like to recommend Zhang Min to be president of the Students' Union.
Zhang Min is warm-hearted and outgoing. She is strict with herself. She is patient enough to listen to other students' ideas and she can get along well with different classmates.
Zhang Min is good at organizing activities and has a strong sense of duty. Last term, she volunteered to organize our school sports meeting and managed to solve many problems. Besides, she set up a study group to help classmates who fell behind in their lessons.
For all of these reasons, I believe that Zhang Min is quite suitable to be president of the Students' Union. I sincerely hope you will consider her for this position. I'm sure she will make the Students' Union more helpful and more popular among all the students.
Yours,
Wang Hua
