四、语法：

it的用法

it作先行词，用作形式主语，代替后面作真正主语的动词不定式或that引导的主语从句。 1．形式主语，代替动词不定式(It is +形容词+ to do sth.)。例如：

It is difficult to walk through eight country parks. 步行穿过八个乡村公园很难。

It is not easy to wipe out the flies and mosquitoes. 消灭蚊蝇是不容易的。

It is everyone's duty to plant three to five trees a year. 每年种三到五棵树是每个人的义务。

It is good to be constantly thinking of helping others. 经常想到帮助别人是好事。

2．用作形式主语，代替动词不定式复合结构(It is +形容词+for sb. to do sth.)。例如：

It is important for students to learn English well. 学生学好英语非常重要。

It is necessary for Ben to explain to his mother why he arrived home late.

对于本来说，向母亲解释他回家晚的原因很有必要的。

It is impossible for him to finish it in ten hours. 他要在十个小时内完成这项工作是不可能的。 3．用作形式主语，代替that引导的主语从句。例如：

It is good that you're so considerate. 你想得这样周到是很好的。

It is necessary that you train yourself before the walk. 在步行前你锻练自己是很有必要的。

It is certain that she will be here. 可以肯定她将会来这儿。

【知识讲解】

1．I don't need money. 我不需要钱。

need在本句中是及物动词，need的用法有三种情况：

①情态动词，（无第三人称单数、过去式和现在分词，通常用于否定句和疑问句），“必须，需要”。例如：

You needn't go yet, need you? 你不一定要去，是吗？

Need you look after your children on Sunday? 星期天你需要照看孩子吗？

②及物动词，“需要，要”。The garden needs rain.花园需要雨水。

“必要；必须”。It needs to be done carefully.此事必须仔细地做。

“值得；该有”。The thief needs a good beating. 这小偷应被好好揍一顿。

③名词，“需要；困境”（不可数名词）。There's no need for you to wait.你不必等。

（用复数）“必需品；要求”。We bought some needs yesterday.昨天我们买了些必需品。

My needs are few.我的需要很少。

2．We can help them cross the road.我们可以帮助他们过马路。

cross the road是省略to的动词不定式，在句中作宾语them的补足语，谓语动词help后面通常可以跟不带to的动词不定式；也可以跟带to的动词不定式作宾语补足语（即

help somebody to do something）。例如：

Please help me (to) carry this heavy case down the stairs.

请帮我把这只沉重的箱子搬下楼。

固定词组搭配：help sb with sth“帮助某人做某事”，“在某些方面帮助某人”，with介词，后面跟名词，构成介词短语，在句中作状语。例如：
