你校位於山腳下，一條小河從旁邊流過，院內樹木四季常青，鮮花爭艷，景色美似花園。但兩年前，附近建起一家化工廠，排出大量污水、廢氣，造成校園污染，嚴重影響了師生健康。請有關部門出面解決這一問題。

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
【寫法指要】
投訴信（letters of complaint）通常是寫給廠家、商店、消費者協會、報界或廠家、商店的上級主管部門，揭發產品質量的低劣、服務態度的糟糕，抱怨不應出現的情況或問題等，以求得解決的信件。寫投訴信要實事求是地把問題講清楚，態度要冷靜，做到有禮貌，不能惡言傷人。
這封信的作者用的是對比法，先寫學校的地理位置和原先學校的優美環境，後寫化工廠建起後對學校造成的污染，最後提請報界呼籲保護環境的問題。寫得有理有據，令人信服。
