九年级英语第十三单元范文

It’s our duty to protect the earth. I always turn off the lights when I leave a room. While I’m washing my hair，I usually turn off the shower. Besides，I stop using paper napkins and if I want to shop ，I always take my own bags instead of using plastic bags.

I have decided to do more things to protect our earth ，such as stopping riding in cars and riding a bike，and recycling books and paper. I think my action can make a difference!
