高考重点:It的用法以及含有it的句型英语中it 一词结构看似简单,但其词义广泛,使用范围很广,常令一些初学者感到头痛。
It用法及其句型和固定搭配,是英语语法的重点、难点,又是近几年考试的热点,在高考中也是重现率较高的语言点,其考查方式多通过“单项填空”进行,偶尔也出现在“短文改错”和“完形填空”中。
因此在复习中应给予足够的重视。
下面笔者就it的用法简单归纳如下。
一、代替上文中提到过的人或事物。
指代人时,一般用于小孩或身份不十分明朗的人。
1) -Who is the baby? -It‘s my teacher’s son.2) -Who is that gentleman? -It's my friend Tom.He(不可用It) wants to see you.不定代词one 指代前文提到的同类事物之一,而it 特指上文中提到的同一事物。
试对比:This pair of shoes is small. May I have another one?(泛指的另一双)这又鞋子太小了,再拿一双给我看看好吗My pen is missing.Ican’td find it.我的钢笔丢了找不到了(it指my pen)二. it 作为无人称动词的主语,表示天气,时间,距离,环境情况等等。
这时的it 不指某个具体的东西。

高考英语It的用法It是高考英语中一个极其重要的词,其用法多样,在不同的语境中具有不同的意义。
下面我们将从it的用法、句型和固定搭配三个方面进行讲解。
一、it用作实词1、表示时间、天气、距离、温度等自然现象。
例如:It is Monday today.今天是星期一。
It is raining outside.外面正在下雨。
It is 5 kilometers away from here.距离这儿有5公里远。
2、表示观点、看法、态度等主观想法。
例如:I think it is a good idea.我认为这是一个好主意。
We think it is important to learn English well.我们认为学好英语很重要。
二、it用作形式主语当不定式、动名词或从句作主语时,为了保持句子结构平衡,避免头重脚轻,常用it作形式主语,代替不定式、动名词或从句,而把真正的主语放在句尾。
例如:It is important to learn English well.学好英语很重要。
It took me an hour to finish the homework.我花了一个小时完成作业。
三、it用作形式宾语当不定式、动名词或从句作宾语时,为了保持句子结构平衡,避免头重脚轻,常用it作形式宾语,代替不定式、动名词或从句,而把真正的宾语放在句尾。

归纳It的用法代词It的用法颇多。
在高考题中屡屡出现,而且历年来一直为高考命题热点,同时也是平时学习的重点与难点。
纵观近几年来的高考试题,不难发现高考对it的考查主要包括以下几种情形:①it用于强调句型;②it用于涉及表示时间的句型;③it作形式主语代替真正主语—不定式短语,动名词短语或that从句;④it充当形式宾语以及指代人或事物等。
下面就结合历届高考试题对it用法考查试加以分析及其归纳。
一、it 用作代词的用法用来指时间、地点、天气、距离、环境等。
it用于指代人或事物,以及时间、距离、天气、自然现象等。
近年来已成为高考热点如: ---What time is it? ---It is ten o'clock now. It is windy today.It is about ten minutes’ walk from here to the station.注:it表示时间时有几个重要句型,同学们要注意掌握他们的用法及其区别。
1)It is time ( about time ,high time ) that ... “是该做某事的时候了”。
该句型中that 后的从句应该用虚拟语气,常用过去时态表示虚拟。
有时也用“should + 动词原形”,should 不能省。
例如:It is time that we had breakfast.I It’s (about/high) time that we should take action.2) It be the first ( second ... ) time that ... “第几次做某事了”。
. 该句型中的that 从句用完成时态。
如果主句动词be是一般现在时,后面从句用现在完成时态;如果主句动词be是一般过去时,后面从句则用过去完成时态。
该结构中that 可以省去。
例如:It’s the third time that he has failed the driving test. It was the first time that I had been praised.3)It be+段时间+ since ... “自从……以来”该句型时间的计算一律从since从句的动作完成或状态结束时算起。
It的固定用法及其易混句型‘it’在英语中频繁使用,也是高考常考词汇。

it作形式主语和形式宾语用法It作形式主语和形式宾语用法,是中学阶段英语学习的主要语法项目之一。
纵观历届高考题,无论是单项选择,还是完行填空,it用法始终是反复考查的重、热点之一。
现将it作形式主语和形式宾语用法,进行如下归纳分析,以供学习参考。
一、It 用作形式主语当不定式(短语)、动名词(短语)或从句在某个句子中作主语时,为保持句子结构前后平衡,避免头重脚轻,因此常用it作形式主语置于句首,而将真正的主语放在句尾。
此时it只起先行引导作用,本身无词义。
e.g. It is wrong to tell a lie.(说谎是错误的。
) 〔It为to tell a lie的形式主语〕It is no use arguing about it.(争吵是没用的。
) 〔It为arguing about it的形式主语〕It is uncertain who will come.(谁要来还不确定。
) 〔It为who will come的形式主语〕It 作形式主语的常见句型(必背):①It + be + 形容词+(for sb)+ to do sth. / doing / that …. e.g. It is very important to learn a foreign language.(学一门外语非常重要。
)It is useless crying over the spilt milk.(覆水难收。
)It was really surprising that she married a man like that.(她嫁给那样的男士真让人惊讶。
)比较:①It + be + 形容词+of sb+ to do sth. / doing / that ….It is brave of him to save the girl in danger without hesitation.(他毫不犹豫地去救那个处于危险中的女孩真是太勇敢了.)②It + be +名词词组+ doing / that ….e.g. It is no good telling lies.(撒谎没好处。
高考英语语法知识之It 的用法总结1.It is + 被强调部分 + that ...该句型是强调句型。
将被强调的部分放在前面,其它部分置于that之后。
被强调部分可以是主语,宾语,状语。
强调的主语如果是人,that可以由who换用。
如果把这种句型结构划掉后,应该是一个完整无缺的句子。
这也是判断强调句型与其它从句的方法。
It was they that (who) cleaned the classroom yesterday. It was in the street that I met her father.2.It was not until + 被强调部分 + that ...该句型也是强调句型。
主要用于强凋时间状语,译成汉语"直到...才...",可以说是 not ... until ... 的强调形式。
It was not until she took off her dark glasses that I realized she was a famous film star.= Not until she took off her dark glasses did I realize she was a famous film star.= I didn’t realize she was a famous film star until she took off her dark glasses.3.It is clear ( obvious, true, possible,certain....) that .....该句型中it 是形式主语,真正的主语是that 引导的主语从句,常译为"清楚(显然,真的,肯定...)"是主语从句最常见的一种结构。
It is very clear that he’s round and tall like a tree.= That he’s round and tall like a tree is very clear.4. It is important ( necessary, right, strange, natural...) that ...由于主句中的形容词不同,that 后的从句中要用虚拟语气(should + 动词原形),should 可以省去。

A, since B, when C, as D, that2, It was __ back home after the experiment.A, not until midnightB, until midnight that he didn’t goC, not until midnight that he wentD, until midnight when he didn’t go三、It be + 时间+ since …在此句型中若从句中谓语动词为短暂性动词,则句型意为:自从(短暂性动词表示的动作开始)以来,已经……时间了;若从句中谓语动词为延续性动词,则句意为:自从(延续性动词表示的动作结束)以来,已经……时间了。
