给校长的一封信，建议改善本校体育设施状况，内容涉及体育设施对大学生的重要性，目前体育设施的状况等，可以表扬，可以批评建议，也可兼而有之。

Dear schoolmaster:

Sports facilities play an important role in college students' daily life.It is necessary of the college to build more sports facilities.In college,students not only study hard but also need the sports facilities to relax themselves or enhance physical during their spare times.

But there are so few sports facilities in our school.That isn't a good news.Students' lives are very dull.Most of them spend their times just in reading room or playing games on net.I advise you to consider this seriously and build more sports facilities.I am looking forward to you answer.

Wish you a smooth work.
