How to protect the environment has become one of the biggest problems in the world .
　　It’s our duty to protect our environment . No matter where we live , we should do something to keep our neighborhood clean and tidy . We can collect waste paper or other waste things for recycling. We should plant more trees and we should prevent those factories from pouring waste water into rivers, lakes and fields. We shouldn’t leave rubbish everywhere and spit in public places . We mustn’t pick the flowers or step on the grass in public. If everyone tries his best to protect the environment , the world will become much more beautiful and our life will be better and better .

如何保護環(huán)境已成為世界上的問題之一。
這是我們的責任來保護我們的環(huán)境。不管我們生活在哪里,我們應該做些事情來保持我們的鄰居干凈和整潔。我們可以收集廢紙或其他廢物回收。我們應該種植更多的樹,我們應該阻止那些工廠將廢水流入河流,湖泊和田野。我們不應該把垃圾無處不在,在公共場所吐痰。我們不能摘花在公共場合或在草地上一步。如果每個人都盡力保護環(huán)境,世界將變得更加美麗,我們的生活將越來越好。
