要点：题中规定了3点。第二步，列出要点，以免遗漏。
1.开头引入、列举由人类活动造成的自然灾难 (pay attention to the natural disasters caused by human activities)
2.人类与自然的关系 (good friends; be kind to nature; live in harmony with nature)
3.人类与自然和谐共处的做法。 (study the rules and laws of nature; protect the environment; protect the animals and plants; reduce the disasters; have a nicer home.)第三步，围绕中心，添加细节。

2.众所周知，大自然是人类的好朋友。人类应该善待自然，与自然和谐相处。

I am Li Hua, a student of Senior One.
I am writing this letter to call on everyone to pay attention to the disasters caused by human activities. Floods, droughts, and dust storms have usually happened on the earth recently. All these have sounded an alarm to humans. As we know, nature is humans’ good friend, so we should be kind to it and live in harmony with it. To achieve this goal, first of all, we must study the rules and laws of nature, and apply them correctly in daily life. Secondly, we should do what we can to protect the environment. Last but not least, we should try to protect all kinds of animals and plants. Only in this way can we reduce the disasters and have a nicer home.
Yours sincerely,
Li Hua第五步，仔细检查，工整书写。I learn! I participate! I experience! I enjoy! 我学习! 我参与! 我体验! 我快乐! 庭业作家1.整理好笔记,并保存好导学案。
