呼吁信-保護(hù)環(huán)境
A Letter of Appeal 呼吁信
目前環(huán)境遭到嚴(yán)重破壞，請(qǐng)寫一封信呼吁大家保護(hù)環(huán)境。
Over the past years, we have witnessed destructions of various kinds caused by human actions. As a university student, write a letter to our society to
　　1)enumerate present severe condition,
　　2)state the necessity of social concern, and
　　3)suggest the counter-measures.
To everyone on our planet,
Over the past years, floods, droughts, landslides, and dust-storms have frequented our planet, the only habitat of human beings. Several days ago, tsunami(海嘯) has swept the Southeast Asia, which has caused enormous damage. All these have sounded an alarm to human beings.
The destruction which is caused by human beings has aroused people’s concern all over the world. If we pay no heed to the present destructive human activities, our planet will become of tomb instead of cozy home. What’s more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.
Counter-measures must be taken to curb the destruction caused by human beings. Most importantly, laws must be established to punish those who are involved in destructive conducts.
　　　　　　　　　　　　　　　　　　　　　　　　Sincerely Yours
