第四课时 Grammar 语法 一、单元语法精讲
（一）it 作代词的用法
it 作代词时，除了作人称代词之外，还有以下用法：
1. it 用来指除人以外的一切生物和事物，可指时间、距离、天气、温度、度量等。

—What’s this/that? 这/那是什么？
—It’s an apple. 是苹果。
3. it 指婴儿或不明身份的人。
Is it a boy or a girl? 是男孩还是女孩？
（二）it 作形式主语
当不定式、动名词、从句等用作主语时，避免头重脚轻，通常在句首使用形式主语it，而把真正的主语放在句子末尾。其常用的句型有：
1. It takes (+sb.) + some time to do sth. 做某事花了（某人）多少时间。
It will take half an hour to walk there.
步行到那里需要半个小时。
2. It is + adj. (for/of sb.) + to do sth.

二、写作范文背记
根据以下提示，写一篇80词左右的英语短文，说明树木对人类的重要性。
提示：1. 树木可以美化环境（beautify the environment），有助于净化空气，有益于身心健康；
???2. 木材有许多用途，不但可用于建筑，还可用于制造许多其他的东西；
???3. 我们应广泛植树和保护树木，严禁乱砍滥伐，以保持生态平衡（the balance of nature）。 Trees can be useful to human beings.
Firstly, trees can beautify the environment and help to make the dirty air clean. They are also good for our health. Secondly, they can not only be used for building houses and making paper, but also can be used to make many other things. For example, many things in our houses are made of wood.
So we must plant more trees and protect them, and we mustn’t cut down trees at will. We must try to keep the balance of nature.
