我很小的时候，老家的天空很美很美，天空很蓝，空气很清新。有一些鸟在唱歌，田野里有许多树。我经常和我的朋友们在露天玩。我喜欢。
Now the people are rich ,but the sky in my homerown isn't blue .the trees were cut down , and there aren't many birds. And the air isn't fresher than before. The rubbish is put here and there, it was bad for our health.So wo must do something to protect the environment. If we make a contribution to protecting the environment,the sky will become much more beautiful.
的人现在很富有，但我家的天空不是蓝色的。树被砍倒了，鸟也不多。空气也没有以前清新了。垃圾到处乱放，不利于我们的健康，所以我们必须采取措施保护环境。如果我们为保护环境作出贡献，天空将会变得更加美丽。
