课件29张PPT。3A healthy life教学目标1. Study the usage of “it”.
2. Do some practice to master the usage of “it”.1.做形式主语It可以用作先行词作为句子的主语，而把句子的真正主语移到后面去，可以移到后面的主语是：
（1）不定式。
句子的谓语可以是
be+形容词；
e.g. It is important to know your limitations.知道自己的局限性是很重要的。 be+名词；
e.g. It is a good idea to have a little notebook handy.手边有个小笔记本是个好主意。
be+介词短语；
e.g. It is against the law to do that.
这样做是违法的。
其他类型的谓语
e.g. It gives me great pleasure to see the movie. 观看电影让我很高兴。（2）动名词用no good, no use, great fun, a new experience等名词作表语；
e.g. It is fun working for him.
为他工作很有意思。
也可用某些形容词作表语；
e.g. Do you think it is worthwhile quarrelling with him？你认为和他吵值得吗？
一些其他的谓语形式。
e.g. Does it matter wasting a little money?
稍微浪费一点钱行吗？（3）主语从句可以是that引导的；
e.g. It is strange that it hasn’t been noticed before.真奇怪，它以前没有引起注意。
It is a wonder that he is still alive.

It was clear enough what he meant.
他的意思很清楚。2. 作形式宾语。 当复合宾语中的宾语是不定式、动名词、宾语从句时，往往把宾语放在它的补足语后面，而用it 作形式宾语，放在宾语补足语之前。e.g. I think it no use arguing with him.
我认为和他争吵没有用。
I found it very interesting to study English.
我发现学英语非常有趣。
He made it clear that he was not interested in this subject.
他非常清楚地表示他对那门学科不感兴趣。3. 用于强调结构 要强调句子的某一部分，通常是主语、状语、宾语，可以把it当作先行词。这种句子的结构是：
“It is/was+被强调部分+that/who+句子的其他部分”。如果强调的是人，可以用who, whom代替that。e.g. It is Prof. Lin who teaches us English.（强调主语）
It is English that Prof. Lin teaches us.（强调宾语）
It was in shanghai that I saw the film.（强调状语）
It was in 2001 that I went to university. （强调状语）
4. 用作人称代词。 代替前文提到的事物。
e.g. The frog is not a warm-blood animal. It’s a cold-blooded one.5. 作为非人称代词（1）起指示代词的作用，指一个人或事物。
e.g.— Who is knocking at the door？
—It’s me.
（2）泛指天气。
e.g. It’s a warm sunny afternoon.（3）泛指时间
e.g. It was nearly midnight when she came back.
（4）泛指环境
e.g. It is noisy here.
（5）泛指距离
e.g. It is half an hour’s walk to the city center. 6. 用于某些习语make it 及时赶到；成功；办成
