参考范文

     The Earth Hour was from 8:30 pm to 9:30 pm on Saturday, March 26th this year. It was the moment my friends and I waited for a long time. We talked and played games at home with all the lights off. We were glad to be in the Earth Hour. As a student, I have done lots of things to protect the envionment. For example, I always carry a cloth bag while shopping. Besides, I often ride a bike to school instead of taking a car. I think we can care for the earth by doing so. Let's take part in the Earth Hour next year.

     I believe that we can make our earth a better place to live.
