经典范文
How to protect our environment
As students, we should try our best to protect our environment.
Now the pollution is more and more serious. Too many cars can be seen on the road. So we should go to school by bike or on foot. And we should also ask our parents to ride bikes to work. We should reuse water. For example, after I finish washing the clothes, I use the water to sweep the floor. I think saving paper is necessary, so I often make full use of paper. At the same time, I never use plastic bags. And I advise my parents to plant some trees behind our house.
It’s important for us to live a low-carbon life to protect the environment. Lower carbon, happier life.

模拟演练
One possible version:
　　In the world, the number of wild animals is becoming smaller and smaller. A few people are killing animals for food and clothes. Some are cutting down trees to build houses. Besides, some farmers use too much pesticide. As a result, wild animals lose their home so they are in danger. Also, some animals don’t have many babies. Some of them may disappear. What a pity!
Unluckily, this has destroyed ecosystem balance and made a few infectious diseases spread. What’s worse, this can make human beings lonely.
In my opinion, it’s time to take action to protect wild animals. The government should keep people from destroying forests as well as set up nature parks. Let’s refuse to kill wild animals for food and clothes from now on.
Animals are human beings’ friends. We should live on the same earth in peace.
