  it的用法

  【考纲解读】

  根据近向几年高考试题来看,it一直是考查的重点,尤其是it, that 和one不同的指代功能。试题注重情景的设置,需要利用特点语言环境中上下文的联系,正确分析结构,理解句意是做此类题目的关键。

  命题的热点集中于以下几个方面: .

  1. it/that/one用法区别(it主要指代前面提到的同一物;one用来指代前面出现的单数名词,相当于a/an+单数名词,表泛指概念,往往是同类而同一物;that用来替代前面出现的特指的单数可数名词或特指的不可数名词,相当于the+单数/不可数名词)

  2. it用在某些动词后,如:enjoy,like,,dislike,resent,hate,don’t mind,be fond of,feel like,see to 之后, 即这些动词后面的宾语从句前要加it代替其后的从句

  3. 用于强调句或固定句型(it is/was …when/since/before…)中.

  4. 作形式宾语或形式主语(主要代替ving,to do或从句)

  5. 考查it 构成的习语,it也常表示抽象的情况,属于虚指. 如:Take it easy.

  t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 factory.

  It is eighteen square metres in area.

  What does it matter?

  (三)作强调词,构成强调结构

  用以帮助改变句子结构,使句子的某一成分受到强调。“It is (was) + 所强调的成分 + that (who) + 其它成分。”在这个句型中,it本身没有词义。注意: 在强调结构中,如被强调部分为时间状语或地点状语,其后的连接词也绝不能为when 或where,而应用that 。在复习中,一定要注意句式的不同。

  It was in Shanghai that I bought the guitar.(that引起强调句)

  It was Shanghai where I bought the guitar.(where引起定从)

  It was twelve o'clock when we arrived there.(when引起时间状语从句)

  It was at twelve o'clock that we arrived there.(that 引起强调句)

  (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.(It与to go there on foot之间夹有takes half an hour四个词) We thought it strange that Mr Smith did not come last night. (it与that从句中间夹有 strange)

  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 support 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)

  (五). it,one,that 的区别:作为代词,这三个词的对比使用是高考的热点之一。

  ---Why don't we take a little break?

  ---Didn't we just have __________?

  A.it

  B.that

  C.one

  D.this

  The Parkers bought a new house but _________will need a lot of work before they can move in.

  A.they

  B.it

  C.one

  D.which

  one 用以指代同类事物中的任一,that 特指性强,指代可数与不可数词,而it指代上文提过的同一事物。

  考点 it的用法

  在英语中,运用it的场合较多。从它在句中的作用和意义来看,it的用法可分为三类:

  1.指代作用

  (1)用作人称代词,代替前文或后文所提到的同一事物(单数可数名词或不可数名词)。如:

  Although we cannot see it,there is air all around us.虽然我们看不见空气,但它却在我们的周围。

  (2)代替前面的整个句子。如:

  It is said that he has died of a disease,but it isn’t true.据说他已经病死了,但这不是真的。

  (3)用在答语中代替指示代词this,that。如:

  一What is this?这是什么?

  一It’s a bike.是自行车。

  (4)代替不能或没有必要区分性别的或某些习惯说法中的人。如:

  ①The baby cried because it Was hungry.婴儿哭是因为饿了。(婴儿习惯上不区分性别)

  ②一Who is knocking at the door?谁在敲门?

  一It’s me.是我o

  (5)指环境、情形等。如:

  ①I can’t stand it any longer.我再也不能容忍这种情况了。

  ②Take it easy.别紧张。

  ③It doesn’t matter.没关系。

  (6)指度量衡单位、时间、距离、季节、天气及自然现象。如:

  ①It’s getting colder and colder now.现在越来越冷了。

  ②It is winter now.现在是冬天了。

  2.形式作用

  (1)形式主语

  当动词不定式、v.ing形式或从句作主语时,通常把它们放在谓语之后,而用it作句子的形式主语。如:

  (I)It’s no use crying over spilt milk.[谚]覆水难收。

  ②It takes three generations to make a gentleman.[谚]十年树木,百年树人。

  (2)形式宾语

  当复合宾语中的宾语是不定式、v-ing形式或宾语从句时,往往把真正的宾语放在补足语后面,而用it作形式宾语,放在宾语补足语之前。如:

  ①You must make it clear to them that the situation is serious.你必须向他们表明形势是严峻的。

  ②)They thought it difficult to talk to the guests about the recent events.他们觉得和客人们谈近来发生的事情很困难。

  特别提示

  形式宾语用在“主语+谓语动词+宾语”结构中,谓语动词appreciate,dislike,hate,like,love,make(按时到达,成功)等后接由if或when等引导的从句时,往往在从句前加形式宾语it。如:

  ①1 would appreciate it if you paid in cash.如果你能支付现金的话,我会不胜感激。

  ②The boy likes it when you do that.那个男孩喜欢你那样做。

  3.强调作用

  it可以用来改变句子的结构,使句子的某一成分得到强调。强调句型的基本结构为:It is/was+所强调的成分+that/who/whom+其他成分。
