【正确答案】Dear Mr. President,
[1]I am a senior in the Biology Department. [2]I'm writing to tell you some problems with the canteen service on campus and some suggestions on it.
[3]We really don't think much of the quality of the food. The rice and bread are too hard for us to chew. The vegetables are often overcooked. [4]Besides, the price of the food is too high. You know, some students' families are very poor, and they are even short of tuition fees. [5] How can they afford such expensive meals? Furthermore, the attitude of the service staff to us is not acceptable.
[6]Therefore, I suggest that we should have more than one canteen in the university. If there is competition between them, the above-mentioned problems will be solved more easily.
[7]I sincerely hope that the canteen service will be improved soon. All of us will appreciate it. Thank you for your consideration!
