School Polluted
No. 1 Middle School
March 5, 1997
Dear Editor,
Our school lies at the foot of a mountain with a small river passing by. It used to look like a beautiful garden. There used to be green trees and all kinds of flowers in our school yard all year round.
But great changes have taken place since a chemical works was built near our school two years ago. It produces poisonous gases and pours a large amount of waste water into the river. The terrible pollution has done great harm to us students and teachers as well as to the surroundings.
It＇s time for us to take steps to protect our surroundings and prevent them from being polluted.
                                                                                                                           Yours ever,
                                                                                                                            Wang Hong
【写法指要】
投诉信（letters of complaint）通常是写给厂家、商店、消费者协会、报界或厂家、商店的上级主管部门，揭发产品质量的低劣、服务态度的糟糕，抱怨不应出现的情况或问题等，以求得解决的信件。写投诉信要实事求是地把问题讲清楚，态度要冷静，做到有礼貌，不能恶言伤人。
这封信的作者用的是对比法，先写学校的地理位置和原先学校的优美环境，后写化工厂建起后对学校造成的污染，最后提请报界呼吁保护环境的问题。写得有理有据，令人信服。
