2011届高考英语一轮复习讲解：it的用法

2011届高考英语一轮复习讲解：it的用法【知识要点】 It的用法（一）作人称代词 1、it代替前面（或后面）的单数名词或分句等所表示的事物。 e.g. You cannot eat your cake but have it.（it代替前面的cake） Although we cannot see it, there is air all around us. （it代替后面的air） They say he has left town, but I don’t believe it.（it代替前面They…town分句中的情况） 2、代替有生命但不能或不必分阴阳性的东西（包括婴儿）。 e.g. Yesterday we saw a big tree. It was fully twenty metres high. （it代替前面的tree） The baby cried because it was hungry. （it代替前面的baby） 3、在某些习惯说法中，可以代替人。 e.g. ---- Someone is knocking at the door, Peter. ---- Who is it? ---- It’s me. ---- Who are singing? ---- It is the children. ---- The light is still on in the lab. It must be the third-year students doing the experiment. 4、it与one的区别：这两个词都可以代表前面说过的名词，但it用于同名同物的场合；one则用于同名异物的场合。 e.g. ---- Do you still have the bicycle? ---- No, I have sold it. ---- Is this knife yours? ---- No. It is Xiao Zhang’s. Mine is the one on the desk. 5、it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。 e.g. The climate of South China is mild（温和的）; I like it very much.（it指the climate of South China） The climate of South China is much better than that of Japan.（that指the climate）（二）作无人称代词 it作无人称代词时，除了句中找不到它所代表的词语外，另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。 It is fine (rainy, windy, etc.). It is noon. It is a half hour’s walk to the f actory. It is eighteen square metres in area. What does it matter? （三）作强调词，构成强调结构

It's time to have supper. (2) “It's time…”后面还可以接一个从句，但是从句中的谓语动词一定要用过去式即虚拟语气，如： It's time we had lunch.是我们吃饭的时候了。 It's time we started.是我们该出发的时候了。 2.it用作引导词 (1) 作形式主语由动词不定式、动词-ing短语或名词性从句担任主语的句子，常用it来作形式主语，而把真正的主语放在句子的后面。 It's not easy for us to learn English well. [句型为: It +be+形容词+（for sb.）to do sth.] It's foolish of you to say that to her. [句型为: It +be+形容词+（of sb.）+to do sth.] It's no use/good/help…sleeping too much.
