英语中it的用法及练习
一、概述
在英语中，it的使用相当广泛，它既可用作代词，如人称代词（personal it）、指示代词（demonstrative it）及非人称代词（impersonal it）, 也可用作引导词（anticipatory it）和强调结构中的强调词（emphatic it）

二、it作代词
1、用作人称代词（personal it）
代替前文提到过的事物，it作真实主语或宾语。

2、用作指示代词（demonstrative it）
相当于this或that，it有时不特指某件东西，而代表前面已提到的或将会发生的某件事情。
-Who is knocking at the door? —谁在敲门？
-It's me. —是我。
I had a talk with the student. It was very helpful to her. 我和那个学生谈了次话，对她非常有帮助。
It happened during my stay in the United States. 事情发生在我在美国的时候。
-Whose exercise book is that? —谁的作业本？
-It's his . —是他的。
3、用作非人称代词（impersonal it）
代词it可用来指除人以外的一切生物和事物，无阴阳性之分。可指时间、距离、度量、价值、自然现象（天气、气体、阴暗等）。
-What's the time? —“几点了？”

-What's the cost of the dictionary? 那本词典多少钱？
It is sixty-three. 六十三元（指价值）
It did not snow much last winter. 去年冬天雪下得不多。（指自然现象）
三、it作引导词
1、作形式主语（formal subject）
当主语是动词不定式短语、动词的-ing形式短语和主语从句时，为了避免头重脚轻，往往把主语放在谓语动词之后，习惯上用it作形式主语来指代后面的真实主语。这个it称为引导词（anticipatory）it，作形式主语，放在谓语动词后的主语是真正的主语。
(1) 代替不定式短语
Is it necessary to complete the design before National Day? 国庆节前完成这个设计有必要么？
In fact, it is a hard job for the police to keep order in an important football match.事实上，在重要的足球比赛时，警察维持秩序很困难。
It's not easy to finish the work in two days. 两天之内完成这个工作不容易。

It is necessary to use a short-wave radio.使用短波收音机很有必要。
It is not a good habit to stay up late.开夜车不是个好习惯。
（2）代替动词-ing形式短语

It is dangerous walking on thin ice.在薄冰上行走是危险的。
It won't be any help my going with you.我跟你去也没什么帮助。
Is it any good trying again?再试一次有用吗？
（3）代替主语从句

It is a pity that you didn't go to see the movie.你没去看这个电影，真是可惜。
Has it been decided when we are to hold the sports meet?我们啥时候开运动会决定了没有？
It is known to all that Christopher Columbus discovered America in 1492.众所周知，克里斯托夫·哥伦布于1492年发现了美洲。
Does it matter if he can't finish the job on time?如果他不能按时完成那工作要紧吗？
2、作形式宾语(formal object)
当复合宾语中的宾语是动词不定式、动词-ing形式短语、宾语从句时，往往把宾语放在它的补足语的后面，而把引导词it放在全句谓语动词和宾语补足语的中间。放在宾语补足语后面的宾语叫真正宾语，放在全句谓语动词和宾语补足语中间的引导词it叫形式宾语。
（1）it代替不定式短语
I don't think it possible to master a foreign language without much memory work. 我认为不进行大量的记忆学好英语是不可能的。

They found it strange that no one would take the money.他们感到奇怪，谁也不要这笔钱。
四、it用在强调结构中
当我们要强调句子的某一部分（通常总是主语，宾语或状语）时，常用强调结构。其形式为“it is (was)+被强调的部分+who(that)+句子的其它成分”。在这种结构中，it无实际意义，它只帮助改变一个句子的结构，使某一成分受到强调。如I told her the news at the gate yesterday. 这个句子就可借助it改为下列几种形式，各强调一个不同的成分。
1、强调的成分
（1）强调主语
It was I that told her the news at the gate yesterday. 昨天在大门口告诉她这个消息的是我。
It is the ability to do the job that matters not where you come from or what you are.是你的能力很重要，而不是你从哪来或者你是谁。
（2）强调宾语
It was her that I told the news at the gate yesterday.昨天在大门口我告诉消息的是她。
It was a pen that he bought in the shop yesterday.他昨天在哪家商店里买的是一支笔。
(3)强调地点状语
It was at the gate that I told her the news yesterday. 我昨天是在大门口告诉她这个消息的。
It was in the bookstore that I met your brother the other day．（上海1990）
前几天我是在书店遇到你哥哥的。
(4)强调时间状语
It was yesterday that I told her the news at the gate. 我是昨天在大门口告诉她这个消息的。
It was not until 1920 that regular radio broadcasts began.直到1920年才开始正规的收音机广播。
It was not until she took off her dark glasses that I realized that she was a famous film star. 直到她拿下墨镜我才认出她是著名的影星。
It was about 600 years ago that the first clock with a face and an hour hand was made. 早在600年前第一座带有表面和时针的钟就造出来了。
2、使用“It is/was…that”强调句型要注意的几点
（1）被强调部分指人时，其后除了用that之外，也可用who或whom。强调的是主语时，使用who；强调的是宾语时，使用whom。
It was Mary who picked up the wallet. 是玛丽拾到了那个钱包。
It was one of my old schoolmates whom I visited yesterday. 我昨天去看的是我的一位老校友。
It was Jack that I met in the park last week.我上星期在公园遇到的是杰克。
It was her that I met in the park yesterday.昨天在公园时里我遇到的是她。
(2)强调句的时态
一般说来，原句的谓语动词如果是现在或将来各种时态，则用句型“It is .... that(who, whom) ... 。”如果原句谓语动词是过去各种时态，则用句型“It was ...that(who, whom)....”
It was only when I reread his poems recently that I began to appreciate their beauty.只是在最近我在读他的诗时才开始欣赏到它的美。
It is Smith who is leaving for Beijing tomorrow.是史密斯先生明天去北京。
(3)在强调时间、地点、原因或方式状语时，不能用when、where、why或how，只用that。
It was because her mother was ill that she didn't go with us.就是因为她母亲病了，她才没跟我们一起去。
It was in Shanghai that the Chinese Communist Party was founded on July 1, 1921.中国共产党是在上海于1921年7月1日建立的。
注意：可用“It is/was because…that…”结构强调because引导的原因状语从句，如上例所示，但不能用该结构强调由since或as引导的原因状语从句，如不能说:It is everybody is here that let's begin our discussion.也不能说: It was as it was raining hard that they had to stay at home.
（4）强调“not...until”结构
在强调“not...until”结构中由until短语（或从句）表示的时间状语时，要用固定的强调句型“It is/was not until ... that ... 。”其中that从句中的谓语动词用肯定式。
My father did not come until 12 o’clock last night.
It was not until 12 o'clock last night that my father came home.昨晚直到十二点我父亲才回家。
It was not until his father came in that the boy began to prepare his lessons．直到她爸爸进来时，那个男孩才开始复习功课。
It was not until she came to see us that we knew her mother was ill in bed．直到她来看我们时，我才知道她妈妈卧病在床。
（5）在强调一般疑问句中的某一成分时，主句要用一般疑问句的语序。
Did this happen in Guangzhou?Was it in Guangzhou that this happened? 此事是在广州发生的吗？
Was it in 1969 that the American astronaut succeeded in landing on the moon？是在1969年美国宇航员成功登上月球的吗？
（6）特殊疑问句中只有疑问词可以强调，其强调结构是：“疑问词+is/was i t +that … ？”
When did you get to know her?When was it that you got to know her?你是在什么时候认识她的？
（7）可以强调方式状语和以because引导的原因状语从句。
It was unwillingly that he did it for me. 他是不情愿地替我做的那件事。
It was because he was ill that we had to come back early.正是因为他病了，我们才不得不早归。
（8）可以强调宾语补足语，当连系动词不是be，表语部分是名词性词组时，也可使用这种结构强调表语，但是，
当连系动词是be时，不能强调表语。
It is white that they painted the house. 他们把房子漆成的是白色。（强调宾语补足语）
It is a chief engineer that he becomes now. 他现在担任的是总工程师。（强调表语）
（9）强调句的谓语动词除了可采用现在时和过去时的单数形式外，有时根据需要还可采用复杂的形式。
It must have been Mary that you saw just now. 你刚才看到的一定是玛丽。

高中英语 it的用法
高中英语it的用法 it的概念： it可用作人称代词、指示代词、先行词及引导词等。 it 的用法： 1、it可指天气、温度、时间、距离等。 如：It is cold today, isn't it? 2、用作人称代词，代替前文提到过的事物。 如：The dog is not acold-blooded animals. It doesn't need to hibernate. 3、为避免重复，it可用来代替前面说过的短语或句子。 如：I tried to persuade my father to give up smoking, but found it impossible. (it=to persuade my father to give up smoking) 4、代替指示代词this，that。 如：—What's this? —It's an album. —Whose new bike is that? —It's Mary's. 注：it与one，that的区别： it=the（this, that）+名词，特指并且代替前面所提到的某特定事物。 如：He's bought a new car, so he drives it everywhere to show ito ff. one=a+名词，one指前面提到的同类事物中的不同的另一个。 如：He needs a computer, but he can't afford one. that=the+名词，that指代的名词与前面的名词属于同一类，但不属同一个。 如：The population of China is larger than that of Japan. that指代population，但其后有一个of短语作定语，以区别于the population of China。 注：it与that的异同： it指同一事物，that指同类但并不是同一事物。 如：I like the climate of Kunming more than that of Beijing. The climate of Kunming is mild, and I like it. 5、It/This/That+be+the first(second, third...) time+that-clause 这个句型表示截止到说话时为止的某人的一种经历，关键是注意time前有序数词，主句是一般现在时is时，从句要用现在完成时；如果主句用一般过去时was时，则从句须相应地用过去完成时。 如：This is the first time(that) these Europeans have visited the Great Wall. It was the fifth time(that) I had paid a friendly visit to America. 6、在一些相对固定的词组中，没有特殊含义，经常不翻译。 如：He's never really made it as an actor. 作为演员，他从未获得过真正的成功。 It is my turn. 轮到我了。 强调句中的it： 可以用来改变句子结构，使句子的某一成分得到强调： 1）强调句的基本句型it's/was+被强调成分+that/who+其他成分 原句：I told Jim the news in our office yesterday.

It的用法及练习题
It的用法 It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。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。 1．It was only when I reread his poems recently ___ I began to appreciate their beauty． A．until B．that C．then D．so 正确答案：B 此题考查强调句，所以用that。 2．I hate ____when people talk with their mouths full．A．it B．that C．these D．them 正确答案：A 此题考查it作形式宾语的用法，所以选A。 3．(短文改错)David and I did not agree and David pointed to a path which he thought it would probably lead to a village．正确答案：去掉it，因为定语从句中已有宾语which。 一、要点点拔 1．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． 2．用于表达天气、环境、时间、距离、季节等。例如： 1) It?s half an hour?s walk from here to our school．2) It…s nice and warm here． 3) But it's two o'clock now, and it's time for us to go to school． 3．用作形式主语.it 没有具体意义，而只是帮助把真正的主语移至句子后尾，使句子显得平稳一些，能借it 给移至句子后尾的主语有三种：一种由不定式表示，一种由动名词表示，一种由从句表示。 1).It 替代真正的主语——动词不定式短语. It is easier to say than to do . It is a good act to help the others. 2).it 替代真正的主语——动名词短语,以动名词短语做主语的句子，主要在以no good, no use, no harm, dangerous, foolish 等词作表语的句中. It?s no harm drinking running water in that area。It?s foolish talking like that. 3).it 替代从句作主语，用从句做主语的带it 的句子很多,常见的有下面几类： ①It is a pity (a shame ,a fact ,a wonder ,a good thing,etc. )that…It is a shame that he didn?t pass the exam. ②It is strange ( surprising,obvious ,true, good,possible,clear,etc. ) that…。It was clear that they had no desire for peace. ③It seems (happened ,turned out,etc.)that… It seemed that things were not as they expected. ④It is said ( decided ,expected ,etc)that … It is said that the tickets have been sold out . 4.用作形式宾语。 当复合宾语中的宾语是不定式,－ing短语或从句往往用it作形式宾语,而将真正的宾语移至句末,句子重心后移。 1) We find it difficult to learn English well in such a short time．2) We think it no use crying over spilt milk． 3) We made it clear when and where we were going to have the meeting． 5．用于强调句型，即“It is/was＋被强调部分＋that/who/whom+其它”句型之中。 使用该句型有以下几点请注意： ①强调句的谓语is或was永远用单数.It was yesterday that I met your father in the street． ②不管被强调部分是哪种状语，只能用that连接，不得使用where、when等连词. It was in the street that I met your father yesterday． ③被强调部分为人时，可用who(主格或宾格)和whom(宾格)代替that，用that也行。 1)It was your father that/whom /who I met in the street yesterday． 2) It was I that/who met your father in the street yesterday． ④强调句中也要注意主谓一致、人称一致和否定转移的问题。 1)It is they who are our friends．2) It was not until ten o'clock that we got home last night． ⑤注意不要混淆强调句和其他从句。It is was…that…为强调句标志，去掉后仍可组成一个完整的句子，只是没被强调,而其他从句一般不具备这一特征。
