2019-2020年高考英语二轮专题总复习 语法精选代词it用法讲义it 的用法在高考经常被考查，仔细分析一下近几年的高考试题，我们不难发现，it用法主要是围绕其作代词时的用法、其作引导词的用法和其表示强调的用法的考查，本文就此作一归类透视，并提出一些提示，希望能对同学们很好地复习备考it这一用法有所帮助。考点一、it作代词时的用法 1用作人称代词，代替前文提到的事，例如： The snake is not a warmblooded animal. Its a cold blooded one. 蛇不是温血动物，它是冷血动物。2用以代替指示代词，例如： -Whats this ? - Its a book. -这是什么？ - 这是一本书。3起指示代词的作用，指一个人或事物，例如： -Whos knocking at the door ? - Its me .-谁在敲门？ - 是我。 4指时间、季节、天气、距离、环境等，例如： Its very cold outside. Put on more clothes. 外面非常冷，多穿点衣服。5.替代词“it, one与that”区别和联系it用来指代前面提到的同一个事物或人；one用来指代前面同名异物的名词, 指的是同类中的一个，所以属于泛指，相当于“a/an+名词”。one只能代替可数名词，其复数形式是ones；that用来指代前面同名异物的名词，指的是同类中的一个，属于特指，相当于“the+名词”。that既能代替不可数名词，也能代替可数名词，其复数形式是those。Do you need my pen? No, thanks, I have got one. (= a pen)你要用我的钢笔吗？不，我自己有一支。The weather in Beijing is colder than that in Shanghai. (= the weather 不可数名词)北京的气候要比上海（的气候）冷得多。 【高考链接】1.一Have you heard the latest news? 一No，what _？Ais itBis there Care they Dare those2.In my opinion, life is the twenty-first century is much easier than _ Athat used to beBit is used to Cit was used toDit used to be3.There is still a copy of the book in the library.

It 2. it 用作形式宾语。不定式、动名词短语或名词性从句作宾语时，如果后面带有宾语补足语，常用it作形式宾语，而把真正的宾语放在宾语补足语后面。例如：He found it very difficult to stop smoking.The professor thinks it no good reading without understanding.【高考链接】1.He didnt make _clear when and where the meeting would be held. A .this B. that C it D. these2.As the busiest woman in Norton, she made _ her duty to look after all the other peoples affairs in that town. A. thisB. that C. one D. it考点三、it 用作强调时的用法用于强调结构，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) + 被强调的部分+ that(who )+ 句子其余部分”。如果强调的主语部分是人，可用who代替that。在这种结构中，it 不可用this或that替代。例如： It was I who / that meet an old friend of my fathers in the street yesterday. (强调主语) It was an old friend of my fathers that I met in the street yesterday. (强调宾语) It was yesterday that I met an old friend of my fathers in the street. (强调时间状语，注意不可用when 代替that) It was in the street that I met an old friend of my fathers yesterday. （强调地点状语，注意不可用where 代替） 注意：下面两个句子第一个句子是时间状语从句，要用when；第二个句子是强调句式，要用that。 It was Dec. 18th when she was born. 她出生那天是12月18日。 It was on Dec.18th that she was born. 她是12月18日出生的。【高考链接】1.It is not who is right but what is right _is of importance.
