When I was very young ,the sky in my hometown was nice and beautiful, the sky was very blue,and the air was fresh. There were some birds singing ,and there were many trees in the fields. I often played with my friends in the open air.I liked it.

Now the people are rich ,but the sky in my hometown isnt blue .the trees were cut down , and there arent many birds. And the air isnt 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.

我很小的时候，家乡的天空很美丽，天空很蓝，空气很新鲜。有一些鸟儿在唱歌，田野里有许多树。我经常和我的朋友们在户外玩耍。我喜欢它。

现在人们有钱了，但在我的家乡天空不是蓝色的了。树木被砍伐，鸟儿也不那么多了。空气比以前差了。垃圾被随处乱扔，这对我们的健康有害。所以我们必须做些事情来保护环境。如果我们为保护环境做出贡献，天空将变得更加美丽。
