　　1、假如你是新华中学的学生，名叫MIKE。去年6月1日我国已经禁止使用塑料袋，你对此有何看法和什么好的建议？

　　参考答案：

　　I’m Mike. I am a student in Huaxing Middle School. Do you know the plastic bags？ Do you often use the plastic bags？ I don’t like them. I think they use the wasting valuable oil their production. And they can’t decompose（分解） in a short time. The plastic bags will make our world worse. I agree with the rule， which people can’t get the free plastic bags in the shops， supermarkets. It encourages people to use their cloth bags and baskets. It’s good for our environment.

　　So I hope all the students in our class stop to use the plastic bags， and use our own cloth bags. I hope we can take care of our environment. Let’s make our world more and more beautiful.
