Burning Is Harmful to People

A few days ago, I went to the railway station to see my friend off. On the way I saw street-cleaners burning dry leaves. What they do is wrong.

Burning things does harm to people. I remembered that our teachers once told us that burning dry leaves would give off smoke and dust which in turn pollute air. And what is more, it would be harmful to people＇s health. When people breathe the air with smoke, the smoke might lead to cancer. As a result, the cancer would cause people to die.

As we all know, leaves can make very good fertilizer. It would be better to collect them for the fields.

【詞語(yǔ)解釋】

fertilizer[＇f+:tilaiz+] n．肥料

【寫(xiě)法指要】

本文分析焚燒樹(shù)葉的害處。引言段最后一句是全文的篇題。擴(kuò)充段第一句是主題句，下面分析說(shuō)：人燃燒樹(shù)葉，樹(shù)葉產(chǎn)生煙塵，煙塵污染空氣，空氣被人吸入，人得癌癥，癌癥致人死亡。這樣就構(gòu)成了一種因果鏈。所以我們說(shuō)，本文是因果鏈分析說(shuō)明文。結(jié)尾段中，作者提出自己的建議。[/U]
