高考英语二轮专题总复习 语法精选代词it用法讲义

手惰市安逸阳光实验学校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 warm—blooded animal. It’s 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:---What’s this ? ---- It’s 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:----Who’s knocking at the door ? ---- It’s me .---谁在敲门? ----- 是我。

4.指时间、季节、天气、距离、环境等,例如:It’s 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。

it的用法:
⑴it用作人称代词:指代前面已经提到过的动物、事物、小孩或性别/身份不明的人,但应注意:指宠物时常用he/she,指大动物(马、大象等)可以用he/she;指祖国或家乡时,常用she.
注意句子:He failed in the examine,and it worried him. He failed in the examine. It worried him.
He failed in the examine,which worried him.
⑵it用作非人称代词:常常用作句子的主语,可以指时间、距离、价格、长度、重量、日期、星期、月份、季节、气候等。

⑶it用作形式主语或形式宾语:根据句子结构的需要,人们常用it作形式主语或宾语,而把真正的主语或宾语(不定式短语、动词-ing短语或名词性从句)放在句末。

注意it作形式主语的常见结构有:
①It+ be + adj/n(for sb)to do sth.
②It +be + adj of sb to do sth.
③It +be + adj /n+ doing sth(一般限于名词fun,good,luck,joy,use,pleasure
或形容词foolish,wonderful,good,nice,interesting,useless,worth等作
表语时,才用it作形式主语,将真正的动名词主语后置)
④It +be + adj./n + that-clause.
⑤It +be+过去分词(如said,proved,known,believed,reported,thought,hoped,
decided,announced, suggested,ordered,demanded,proposed,requested,advised
等)+that-clause.注意如果表语是划线部分的词,从句应该用虚拟语气。

⑥It takes sb some time to do sth.
⑦It seems/looks as if….
⑷it用在强调句型中:
强调句型“It is/was + 被强调部分 + 其他”的用法
①这一句型可以强调除谓语、表语、定语和同位语以外的任何部分;如果被强调的部分是人,可以用who/that,如果被强调的部分是事物,只能用that。

如:It was I who/that came here late this morning. It is a book that is on the desk.
②注意该句型不能强调让步状语从句;强调原因状语从句时,只能用because,不能用
since,as等;强调not…until句型的时间状语时,要把not与until放在一起。

另外,not until放在句首时句子必须倒装。

如:It was although it was snowing that they went out. (×) I was because he had noticed them watching him that he turned away. It was not until yesterday that he finished his homework. Not until yesterday did he finish his homework?
③在这一句型中,不管强调的主语是单数还是复数,系动词只能用is或was(一般情况下,当句子时态表示现在或将来时用is,当句子的时态表示过去时用was)。

如:
It is Jim that will go to the park tomorrow. It was Lily that finished her work.
④注意这一句型变否定句、一般疑问句、特殊疑问句和反意疑问句的变法。

特殊疑问句
变强调句型时,只强调特殊疑问词,其结构为:特殊疑问词+is/was+it+that….如:
Is it farming that he likes to take up? Who was it that/who won first in the long jump?
Why was it that he came late? It was I that came here late this morning,wasn’t it?
⑤注意把强调句型和“it作形式主语,that引导真正主语从句的句型”区别开来。

如果
把强调句型的结构标志去掉后,句子结构和意思仍然完整的为强调句型。

如:It is natural that he doesn’t do it at all.(主语从句) It was yesterday that I met him.(强
调句型)
注意:强调动词时,不能用强调用句型,可以把助动词do,does,did用于一般现在时
和一般过去时的肯定陈述句中,与动词原形连用,以加强语气,在句中要重读。

如:I do think he is right. He did tell me that he would join us in the work.
⑸it引起的几个易混的时间句型。

①It's time…that从句,从句中谓语动词需要用虚拟语气(“should+动词原形”或动
词过去式)如:It's time that we started out/should start out.
②This/It is the first/second…(序数词) time + that 从句(从句中常用现在完成
时态)
This/It was the first/second…(序数词) time + that 从句(从句中常用过去完成
时态)It/This/That +is/was/will be +first(second…)time+that-clause.本结构中,其中的序数词也可以修饰day,month,year等名词。

如:This is the second time that she has rung you today.
③It will/won’t be + 时间段 + before从句(从句用一般现在时态)
It was + 时间段 + before 从句(从句用一般过去时态)
注意:这种句式分为两种情况:主将从现,主过从过(即主句用将来时态时,从句用一般现在时态,表示过了多长时间以后即将发生某事;如果主句为过去时态,从句也用过去时态,表示多长时间之后发生了某事。

)如:
It won’t be long before he succeeds. It was ten years before they met again.
④It is/has been + 一段时间 + since 从句(从句中常用一般过去时态或现在完成时态)
It was/had been + 一段时间 + since 从句(从句中常用一般过去时态或过去完成时态)
注意:此句型中如果since从句中谓语为延续性动词,翻译时应翻译为否定式。

如:It is five years since he (has) arrived in China.
他来中国已经五年了。

It is five years since he (has) smoked a cigar.
他戒烟已经五年了。

注意以上两句的区别。

It was five years since he (had) arrived in China.
⑤It is/was+具体时间点+when…本结构是定语从句句型,具体的时间点是先行词。

如:
It is five o'clock in the afternoon when they climb up to the top of the mountain.
(6)it的模糊用法
①it + that 可以引导宾语从句,这样的动词或词组有: see to it(确保),depend on, rely on, insist on, take(猜想、认为)。

如:
I take it that he is not fond of reading this novel.
Our teacher saw to it that our homework should be finished on time.
② like, love, appreciate, enjoy, dislike, hate it + 介词短语 + when引导的宾语从句。

如:
I hate it in the evening when you sing.
③ make it表示“成功办到、做到、赶上”。

如:
He tried to jump over the fence and finally he made it.
④ as it is用于句首,表示“事实上”,用于句末,表示“照原样”。

如:
I thought he would get better, but as it is he is getting worse. Leave the chair as it is.
⑤ as it were意为“可以说,在某种程度上”。

如:
He is, as it were, a walking dictionary.。
