6月5日是"世界環(huán)境保護日"，李平和他的同學經(jīng)過討論，覺得有必要向《21世紀報》寫一封信，呼吁人們齊心協(xié)力，保護環(huán)境，提出有效的保護措施．要點如下：
1．不要亂扔垃圾，應該保持環(huán)境清潔；
2．植樹造林，保護環(huán)境；
3．保護海洋，禁止過度捕魚；
4．充分利用自然資源．
注意：
1．詞數(shù)100個左右；
2．可適當發(fā)揮，但不要逐句翻譯．
3．信的開頭和結尾已給出，不計入總詞數(shù)．

Dear editor，
Nowadays，pollution is getting worse and worse．The damage to the environment is getting serious．In my opinion，we should take some measures to protect the environment．
To protect the environment，I think we should do the following things．Some useful garbage can be recycled，while the harmful things should be put in a safe place．（高分句型一）Smoke and gas should be cleaned before they go into the air．If too many trees are cut down，forests will disappear．We should do our best to take good care of the environment．For example，we should plant trees and stop using wooden chopsticks and stop throwing garbage everywhere．（高分句型二）With modern fishing methods，more and more fish are caught．If too many fish are taken from the sea，there will soon be none left．If the rivers are polluted，we will die from the poison．We should make full use of natural resources，or we will be in great danger very soon．（高分句型三）
Yours，
Li Ping
