We have only one earth ,so it is important to protect the environment. First, we should live a low-carbon life, we'd better travel by bike or on foot instead of taking a car. We should take a bag with us when we go shopping instead of using plastic bags. We'd better not waste electricity,paper and so on. Secondly, we shouldn't spit in public or litter things. We should put the rubbish into the dustbin. We'd better plant more trees, grass and flowers instead of cutting down the trees. I believe if everyone makes a contribution to the environment, our world will become more and more beautiful.

　　我們只有一個(gè)地球，所以。保護環(huán)境是非常重要的。首先，我們應該過(guò)低碳生活。我們因該用騎車(chē)或步行替代開(kāi)車(chē)。購物時(shí)，應該自己準備袋子而不應該使用塑料袋。我們不應該浪費紙張和電力等等。其二，我們不應該在公共場(chǎng)所隨地吐痰或亂丟雜物。垃圾應該進(jìn)垃圾桶。我們應該多植樹(shù)，種草種花，不應亂砍亂伐。我相信，如果每個(gè)都做出貢獻，我們的世界就會(huì )變得更加美麗。
