Protect the Natural World

Protect the Natural World
The natural world is home for all living things. We get fresh air, clean water and food from nature, so protecting it is just protecting ourselves.
However, nature is facing many problems now. People cut down lots of trees, many wild animals lose their homes, and air and water pollution is getting worse.
As students, we can do small things to make a difference. We can save electricity and water, use both sides of paper, and plant more trees. Let's work together to protect our natural world.

这是一篇命题式环保主题英语短文写作，写作思路如下：
1. 审题：明确要求覆盖三个指定要点，词数控制在80左右，不得出现真实姓名、校名，语言符合八年级英语词汇难度即可。
2. 谋篇布局：
① 开篇点明保护自然的重要性：自然是所有生物的家园，为人类提供生存必需的各类资源，保护自然就是保护人类自身。
② 中间部分列举当前自然面临的典型问题：森林被过度砍伐，不少野生动物失去栖息地，各类污染日益加剧。
③ 最后给出中学生可践行的具体保护举措，发出行动呼吁，贴合黑板报的宣传属性。
