Dear friends,

Do you want to live in a beautiful world? If so, it is our duty to protect the environment. To fulfill this task, we should bear the following in mind.

To begin with, we should stick to the habit of going to school on foot or by bike. In addition,  we should protect the environment of our school by not throwing rubbish around. Remember to turn off the taps and the lights when we don’t use them and it’s important to recycle everything that can be recycled. Last but not least, we should care for plants and trees in our schoolyard and be civilized students. Only in this way can we make our schoolyard more and more beautiful.

Let’s all take action now and contribute to the environmental protection.  

Thank you!

The Students’ Union

题目分析：本文是一个倡议书，也是提纲作文，应该按所要求的内容来写，根据所列的内容尽量以简明扼要的语言来表达。这篇作文要求较灵活，题目中只是一个提纲，还要考生去充实里面的内容：比如自己好的学习习惯应是能够提高学习效果的，不好的学习习惯会阻碍学习的。写作时要注意使用高级的词汇和复杂的句型，也要适当地使用关联词承前启后，用词要得体，符合语言环境。

【亮点说明】范文中有一些很好的短语：stick to “坚持”，care for“关心”take action “采取行动”，contribute to 有助于，还有一些复杂的句式：If so,  it is our duty to protect the environment. 这句话用了省略句和it做形式主语，To fulfill this task, we should bear the following in mind. 这句话用了不定式做目的状语， Remember to turn off the taps and the lights when we don’t use them and it’s important to recycle everything that can be recycled. 这句话里面有定语从句， Only in this way can we make our schoolyard more and more beautiful.这句话是倒装句，还有文章还使用了一些关联词To begin with, In addition,  Last but not least, 使文章更加连贯。
