1、（一）强调句句型1、陈述句的强调句型：It is/ was +被强调部分（通常是主语、宾语或状语）+ that/ who （强调主语且主语指人可以用who,当然也可以使用that） +其它部分。强调句式只是把句子中某些词（被强调部分）改变位置，所以把强调结构（it is/was. that/who ）去掉之后，句子一定是完整的.It was yesterday that he met Li Ping.2、一般疑问句的强调句型：同上，只是把 is/ was 提到 it 前面。这是重点 . Was it yesterday that he met Li Ping?3、特殊疑问句的强调句型：被强调部
2、分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分？ 一定要注意,这是出题点,也是考点,掌握它的最好 方法是多记几个这样的句子,最后一定会融会贯通的. When and where was it that you were born?4、强调句例句：针对 I met Li Ming at the railway station yesterday. 强调主语： It was I that （who） met Li Ming at the railway station yesterday. 强调宾语： It was Li Ming that I m
3、et at the railway station yesterday. 强调地点状语： It was at the railway station that I met Li Ming yesterday. 强调时间状语： It was yesterday that I met Li Ming at the railway station.5、注意：构成强调句的 it 本身没有词义；强调句中的连接词一般只用 that, who， 即使在强调时间状语和地点状语时也如此，that, who不可省略；强调句中的时态 只用两种，一般现在时和一般过去时。原句谓语动词是一般过去时、过去完成时 和过去进行
4、时，用 It was ，其余的时态用 It is 。（二）not until 句型的强调句 这也是出题点和考点,掌握的方法: 多记几个 这样的句子,最后一定会融会贯通的.1、句型为： It is/ was not until + 被强调部分 + that + 其它部分e.g. 普通句： He didnt go to bed until/ till his wife came back.强调句： It was not until his wife came back that he went to bed.2、注意：此句型只用unti 1,不用till。但如果不是强调句型，till, until
5、可通用； 因为句型中 It is/ was not 已经是否定句了， that 后面的从句要用肯定句，切勿 再用否定句了。（三）谓语动词的强调1、It is/was that 结构不能强调谓语，如果需要强调谓语时， 用助动词 do/ does 或 did。 . Do sit down. 务必请坐。 He did write to you last week. 上周他确实给你写了信。 Do be careful when you cross the street. 过马路时，务必（千万）要小心啊！、 2、注意：此种强调只用 do/ does 和 did ，没有别的形式；过去时用 did ，后 面
6、的谓语动词用原形。二、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。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 dont believe it.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 ful
7、ly 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。Someone is knocking at the door, Peter. Who is it? Its 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 on
8、e 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。- Do you still have the bicycle? No, I have sold it.s this knife yours? No. It is Xiao Zhangs. 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
9、 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 hours walk to the factory.It is eighteen square metres in area.Wh
10、at does it matter?（三）作强调词，构成强调结构（四）引导词 it 作形式主语（宾语）为了使句子平衡，常采用形式主语（或宾语） it ，而把真正的主语（或宾语）置于句子后面。通常引导词 it 与它所代替的句 子成分中间要夹有某些词。 e.g. It takes half an hour to go there on foot.We thought it strange that Mr Smith did not come last night.但有时 it 与所替代部分之间并不夹有其它词。e.g. You may depend on it that they will supp
11、ort you.（因为介词 on 之后一般不直接 接that引导的宾语从句。注意：it不是多余的，不能当作错句）补充: I like it here. 句中 like 是及物动词（什么是及物动词,就是可以直接加上宾语 的动词）,后面必须加一宾语,而 here 是副词,不能作宾语（大家想一想,前面我们说 过什么可以做宾语来的.名词!）这时为了使句子语法正确,使用一个虚拟的宾语: it. 上面说的是理论,掌握起来非常简单哟.把它背下来: I like it here.1. My bike is missing. I cant find anywhere.A. one B. onesC. it D.
