求新视野第四册读写教程unit 1 section a续写

I am a freshman this year.I am writing to make a complainment.The food in our school is not pleasant to eat.The type of the dish is dull and lacks variety.I always have hardly any appetite for eating in the canteen once saw the same dish.
What is more, the staffs in the canteen wree not so friendly.They are temperamental.So I can not have a good mood when eating in the canteen.Last but not least,the sanitation in the canteen is very bad. The dining tables are full of Left-overs just a few minutes after the dining time.It affacts our appetite and heath.
However,there are some good points.The facilities in the canteen is good for our hearth.
I hope the department concerned would take meatures as soon as possible to improve the dining enviroment in the canteen.
Sincerely Yours,
