【正确答案】Honorable President,
As an undergraduate of this university, I'm writing this letter to put forward my suggestions about improving students' physical condition which I believe should be deemed as a very important part of campus life.
On the one hand, we should arm our students with stronger awareness of physical health. I think, more lectures and courses on health maintenance and dietary balance should be regularly provided on campus. On the other hand, it is necessary to build a well-equipped gymnasium and more sports facilities near dormitory areas so that students can take advantage of their convenience.
I will deeply appreciate it if you can take my suggestions into consideration.
Sincerely yours,
Li Ming
