【正确答案】Sample Writing Dear Manager Li, I am the president of Student Union in our school. On behalf of all students, I am writing to express our views concerning some problems that exist in our canteen. First of all, it is not hard to find that the prices of a large number of dishes have risen. What's more, the varieties of dishes are so limited that many students have to eat instant noodles. To solve these problems, it is necessary that effective measures should be taken. Firstly, the price of some food should be reduced. Secondly, some new kinds of dishes should be added. It is hoped that you take the problems and our suggestions seriously and make efforts to improve the services of our canteen. Yours sincerely, Li Ming
