六年级英语优秀作文精选：We have only one world 我们只有一个地球
It’s our duty to protect the environment. I think we should keep ourschools and cities clean and tidy. Here are some of my views:
Don’t spit in public and throw rubbish everywhere .And we should plant
trees and flowers around the city. It’s important to recycle paper and water.
Don’t forget to turn off the lights when we leave the room. We had better walk
or ride bikes to school to keep our streets clean. We must do our best to make
our world more and more beautiful in the future. Do you think so ?
