Dear Headmaster, I am the minister of students' life in the Student Union. On behalf of all the students, I am writing to you to give our opinions about the canteen. Our canteen has something satisfactory and something unsatisfactory as well. To our satisfaction, many kinds of the food are supplied to us. Besides this, the food is cheap and tastes good. We all enjoy the food. And the surroundings in the canteen have also been improved. But the quantity of a helping they give is not enough. The seats are not enough as well.Some students have no seats when eating. Finally we advise them to improve the quality of the food and their service. We will feel very happy if these problems can be solved. Yours, XXX尊敬的校长： 我是学生会生活部部长。我代表所有学生给您写信反映一下我们对食堂的意见。 食堂有令人满意的一面也有令人不满意的一面；令我们满意的是，食堂给我们提供了很多种类的食物。另外，饭菜价格便宜，味道可口，我们很喜欢。而且食堂环境也已经改善了。但是他们给的食物的分量不足。食堂的座位也不够，一些学生吃饭时没有座位。我们希望学校会考虑增添些座位。 最后我们建议他们改进饭菜的质量，改善服务。如果这些问题能被解决我们会感到非常高兴。 尊敬您的 XXX
