it 用法及常见结构
it是大纲要求必须掌握的代词之一。它不仅可以指代时间、地点、天气、环境、距离等；还能作形式主语和形式宾语；同时可以引起强调结构。在高考中出现率很高。请看下面几道高考题：
1．The Parkers bought a new house but _______ will need a lot
of work before they can move in．（NMET 2001）
A．they
B．it
C．one
D．which
2．I hate _______ when people talk with their mouths full．（NM
ET 1998）
A．it
B．that
C．these
D．them
3．Tom's mother kept telling him that he should work harder，but
_______ didn't help．（NMET 1993）
A．he
B．which
C．she
D．it
4．I was disappointed with the film ，I had expected _______ to
be much better．（NMET 1993）
A．that
B．this
C．one
D．it
5． _______ is a fact that English is being accepted as an
international language．（NMET 1995）
A．There
B．This
C．That
D．It
这些都是考查代词it的用法。答案1—5为BADDD。it用法的重要性由此可略见一斑。请看it主要都有哪些用法：
一、用来表示时间、天气、地点、自然环境、距离等。例如：
1．It was five o'clock when we got back home yesterday．
2．I'm afraid it is going to rain today．
3．It is very quiet in the café．
4．How far is it from Tangshan to Beijing？
二、用来指代人。说明某人的身份或者做某事的人。在不清楚某人性别时，也可使用 it。尤其在问答的形式中更为常见。例如：
1．A tall man stood up and shook hands．It was Captain Lawrie．
2．（Last night your sister had a baby，you may ask：）Is it a boy
or a girl？
三、用来指代前文中提到的东西。既可指代具体的东西，也可指代一种情况。请看下面的例子：
1．I hear you bought a new bike，can you show it to me？
2．If I can stop her coming to you，I shall do it．
3．—I want to stay here for a night．
—Your wife won't like it．
此时要注意与其他代词如that，one， those，this，another等的区别：
1．I hear you bought a new bike，I want to buy _______
，too．此处应填one，因为这里我并不是要买你的车，而是一辆新车，one ＝a new bike。
2．I have bought a new bike，but I still want to buy _______
．此处应填another。我已有了一辆，再买另一辆。another ＝another new bike。
3．We see him when we come to town， but _______ isn't
often．此处填that或it均可。指代前面我们去城里时可以看到他这一情况。
4．My seat is next to _______ of the
headmaster．此处应填that，用来代替名词seat，that＝the seat。
5．The bikes made this year are better than _______ made last
years．此处应填those或the ones。代替前文的bikes，因其是复数概念，故用those或the
ones，those ／the ones＝the bikes。
四、用来泛指一般情况或在一些词组中出现，没有特殊含义，常不翻译。例如：
1．It is my turn．
2．Let's call it a day．（今天就到这吧。）
3．If the teacher sees you doing that，you will catch it．
（如果老师看到你这么做，你就会挨批评。）
4．Go ahead，we'll make it in the end．（继续干吧，我们最后会成功的。）
5．—I will study hard in the future．
—That's it．（这就对了。）
五、用来作形式主语或形式宾语。指代不定式、动词的-ing形式、从句等。例如：
1．It is good for you going to bed early and getting up early．
2．I think it no use arguing with him over this matter．
3．It is my duty to teach English well．
4．Is it possible that computers can take the place of human
beings ？
5．I want to make it clear to the class that I didn't steal his
pen．
it代替从句作形式主语的常见句型有：
1）It ＋be的适当形式＋过去分词＋that从句
It's said that Tom has come back from abroad．
据说汤姆已经从国外回来了。
It was reported that dozens of children died in the
accident．
据报导，数十名儿童在事故中死亡。
可用于该句型的过去分词还有known， thought，told，believed，hoped，announced
，expected，decided，suggested等，该句型常可以转换成含有宾语从句的复合句或者含有不定式作主补的简单句。例如：
It's said that Tom has come back from abroad．→People say that
Tom has come back from abroad．→He is said to have come back
from abroad．
2）It ＋be的适当形式＋名词词组＋that从句
It's a pity that he can't swim at his age．
真遗憾，就他的年龄来讲，他竟不会游泳。
It's a wonder that you could finish such a hard task in
such a short time．
真奇怪，你竟能在如此短的时间内完成如此艰巨的任务。
可用于该句型的名词词组还有an honour，a good thing，a fact，a surprise，good
news等。
3）It ＋be ／seem的适当形式＋形容词＋ that从句
It is likely that they will beat us tonight．今晚很可能他们会赢我们。
It doesn't seem possible that she will give us a
hand．她帮我们的可能性似乎不太大。
可用于此句型的形容词还有wonderful， true，good，right，wrong，（un）important
，useless，surprising，clear，unusual，lucky，certain等。
4）It ＋seem／appear ／happen的适当形式＋that从句
It seems that he enjoys pop songs very much．看来他非常喜欢流行歌曲。
It happened that I went out that day．碰巧我那天外出了。
注意，句型4）可转换成含不定式的简单句。如上述两句可分别转换为：
He seems to enjoy pop music very much．
I happened to go out that day．
5）it代替连接代词或连接副词引导的从句作形式主语
（1）It is known（not decided，not made clear，found
out，discussed，being discussed，being considered，a
question，uncertain等）＋连接代词或连接副词引导的从句。
It is still a question when we shall have our sports meet．
我们将什么时候举行运动会还是一个问题。
It is uncertain whether he can attend this conference or not．
他能否来开会还不能确定。
（2）It doesn't matter（It's no wonder；It doesn't make too much
difference等）＋连接代词或连接副词引导的从句。
It doesn't matter whether we go together or
separately．我们一起去还是分开去都可以。
It is no wonder why he came here too late．他为什么来这么晚不足为怪。
六、it引起的几个易混淆的时间句型。
1．It ＋be的适当形式＋一段时间＋ since-clause
这个句型表示从since从句谓语动作发生以后到现在或过去所经过的一段时间，意为“自从……以来已多久了”，主句多用一般现在时，从句用一般过去时；如果表示过去的情况，主句用一般过去时，从句用过去完成时，或主句用过去完成时，从句用一般过去时。例如：
It is／has been three years since his father passed
away．他父亲去逝已经有三年了。
It was 10years since they married．他们结婚十年了。
It had been fifteen years since she left Shanghai．她离开上海已经15年了。
2．It ＋be的适当形式＋一段时间＋before-clause
这个句型中的时间一般为表示一段时间的词语（如：long，years，months，weeks，days ，
hours，minutes），主句中的谓语动词用肯定式，意为“过多长时间才……”。主句的谓语动词是否定式时，意为“没过多长时间就……”。主句的时态可用过去时was或将来时
will be；用was时，before从句的动词用一般过去时；用will be时，before从句常用一般现在时。例如：
It was not long before she learned those poems by heart
．她没过多久就背会了那些诗歌。
It was long before the police arrived．过了很久警察才来。
It will be hours before he makes a decision．要过好几个小时他才会作出决定。
It will not be hours before we meet again．要不了几个小时我们还会再见面的。
3．It ＋be的适当形式＋时间＋ when-clause
这个句型中，it指时间，而且表示时间的词语前没有介词（时间一般为具体时间）。主句中的谓语动词和从句中的谓语动词在时态上一般是一致的，主句是will
be，when从句用一般现在时代替一般将来时。例如：
It was already 8o'clock when we got home．
It will be midnight when they get there．
4．It ＋be的适当形式＋time＋ that-clause（虚拟语气）
这个句型属虚拟语气结构，不管主句中 be用的是is或was，that从句都须用动词的过去式或should
＋动词原形（但不及用过去式普通），在time之前有时可加上high或about以加强语气。例如：
It is time（that）we handed in our exercises．（＝It is time that
we should hand in ourexercises．）
It is high time（that）she wrote a letter to her boyfriend．
5．It ／This／That ＋is／was ＋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，主句的谓语是is时，从句要用现在完成时；如果主句的谓语用一般过去时was，从句则须相应地用过去完成时。例如：
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
Africa．
七、用来引起强调结构。It强调句型已在本期第8页有所详述，此处不再赘述。

技术支持 南京大汉网络有限公司高考英语It的用法 命题走向与解题策略
湖南省涟源市私立行知中学 曾省初
【高考走向】
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。
【典型例题】
(NMET98，单项填空)
It was only when I reread his poems recently____I began to appreciate
their beauty．
A．until B．that C．then D．so
【思路点拨】B 此题考查强调句，所以用that。
【知识在线】
It 的用法主要包括以下内容：
1．代替上文中提到过的人或事物，既可以代替可数名词单数，也可以代替不可数名词。 指代人时，一般用于小孩或身份不十分明朗的人。
例如：
－Who is the baby －It's my teacher's son．
－Who is that gentleman －It's my friend,Tom．He(不可用It)wants to see you．
【高考考例】1。Someone is ringing the bell．Go and see____．
A． who is he B．who he is C．who is it D．who it is
【思路点拨】it可以指child，baby或性别尚未确定的人，如在打电话或有人敲门等情形时可用it。
【高考考例】2。I was disappointed with the film．I had expected ____ to be much better．（NMET93）
A．that B．this C．one D．it
【思路点拨】it指代前面的可数名词单数the film。
2．用于表达天气、环境、时间、距离、季节等。
例如：It's half an hour's walk from here to our school．It's nice and warm
here．But it's two o'clock now,and it's time for us to go to school．
【高考考例】3。__________from Beijing to London！（ NMET1990）
A．How long way it is B．What long way is it
C．How long way is it D．What a long way it is
【思路点拨】it用作形式主语，常出现于表时间、天气、气候、温度、地点、距离等意义的句子中。
【高考考例】4。—What was the party like？
—Wonderful！It's been years ____ I enjoyed myself so much．
A． after B．when C．before D．since
【思路点拨】it常用在以下句型中：It is ＋时间段＋since ＋主语＋did．．．，意思是“自从……以来已有一段时间”。
3．用作形式主语或形式宾语。除it外，其他代词没有这种用法。
当作主语的不定式、－ing短语或从句太长时，往往用it作形式主语，而将真正的主语移至句末，以避免句子头重脚轻。
例如：It's not easy to learn English well in such a short time．
It's no use crying over spilt milk．
It's not decided yet when and where we're going to have the meeting
【高考考例】5.It ____ possible to fly to the moon in a spaceship？(MET88，单项填空)
A．now B．that C．it D．man
【思路点拨】 C此题考查it作形式主语，不定式作真正的主语。
【思路点拨】D此题考查it作形式主语，主语从句作真正的主语。
.6。___ is a fact that English is being accepted as an international language．(NMET95，单项填空)
A．There B．This C．That D．It
【思路点拨】D此题考查it作形式主语，主语从句作真正的主语。
7.It is the ability to do the job _____ matters not where you come from or what you are.
A.one B.that C.what D.it (NMET2000)
【思路点拨B此题考查it作形式主语，不定式作真正的主语。
。
②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，以使句子重心后移。
例如：We find it difficult to learn English well in such a short time．
We think it no use crying over spilt milk．
We made it clear when and where we were going to have the meeting．
③包含介词的短语运动接宾语从句时，必须先由it担任形式宾语，再接从句。
例如：Please see to it that all the windows are closed before your leave
the room．
You may depend on it that everything will be all right．
【高考考例】 8。I hate____when people talk with their mouths full．
A．it B．that C．these D．them (NMET98)
【思路点拨】A 此题考查it作形式宾语的用法，宾语从句
9.I don't think ___ possible to master a foreign language without much momory work．
(MET90，单项填空)
A．this B．that C．its D．it
【思路点拨】D此题考查it作形式宾语的用法担任，真正的宾语。
4．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，其中is既可强调现在的情况，也可强调过去的情况，was只能强调过去的情况。
例如：It was/is yesterday that I met your father in the street
【高考考例】10。It was for this reason ____ her uncle moved out of New York and settled down in a small village．
A． which B．why C．that D．how
【思路点拨】C 此题考查it用于强调句型, 强调介词短语for this reason。
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。
例如：It was in the street that I met your father yesterday．
【高考考例】11.It was about 600 years ago ___ the first clock with face and an hour hand
was made． (NMET97，单项填空)
A．that B．until C．before D．when
【思路点拨】A 此题考查it用于强调句型。
12 .It was only when I reread this poems recently _____ I began to appreciate their beauty.
A.until B.that C.then D.so (NMET97)
【思路点拨】D 此题考查it用于强调句型
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。
例如：It was your father that/whom /who I met in the street yesterday．
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。
例如：It is they who are our friends．
It was not until ten o'clock that we got home last night．
【高考考例】13.It was not until 1920 ______ regular radio broadcasts began.
A. while B.which C.that D.since (NMET94)
【思路点拨】C 此题考查it用于强调句型
14.It was not _____ she took off her glasses _____ I realized she was a famous film star.
A. when , that B.until , then C.until , that D.when , then (92)
【思路点拨】C 此题考查it用于强调句型
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，而其他从句一般不具备这一特征。
比较：It was ten o'clock when we got home last night．我们昨晚到家时已十点了。
It was at ten o'clock that we got home last night．
我们昨晚是在十点到家的。
第一句不是强调句，when不可改为that,因为去掉it was和that后，只能组成“We got
home ten o'clock last night．”这样一个不完整的句子；第二句是强调句，that不可
改为when．
【高考考例】15。 ____ is known to everybody，the moon travels round the earth once every month．
A．It B．As C．That D．What (NMET2001)
【思路点拨】as引导非限制性定语从句，本句可转换成：It is known to everybody that the moon travels round the earth once every month．，此时的it是形式主语。

it的用法及系列动词专练50题参考答案与简析
1.D。it指代上文提到的事。另外，指代上文提到的情况，还可用that；指代下文的情况用this。2.D。it作人称代词,用来指代身份和性别等不明确的人。3.D。it作形式主语,真正主语为不定式复合结构for sb. to do sth.4.D。it指代前一分句的内容。5.D。it作形式主语，代替if从句所表达的内容。6.C。it作形式主语，代替真正主语that从句。7.C。it作形式宾语，代替后面的that从句。8.C。can’t／couldn’t help (it)意为“是没有办法的事”，“控制不了”。9.D。在it ＋be＋一段时间＋before／after／since句型中，before从句中的动作经过该段时间后才会实现；after从句中的动作完成后已经过去了一段时间；since从句中的动作完成后到现在已经有一段时间了。10.D。参见注9。11.D。one作为不定代词用来代替上文出现的单数可数名词；it为人称代词，指代前面出现过的某个事物；that常用来指代上文提到的不可数名词。12.C。it在此指时间,与being March 12th 构成独立主格结构，在句中作状语。13.B。表示对过去情况的猜测，用“情态动词＋have done”；而it代替上文所指的new comer。14.B。who引导的从句是强调句型，在句中作宾语,用陈述语序。15.C。it’s the second ／third time that 后的从句用完成时态。16.A。it’s a long way中，it 代替距离，表示“那是一段很长的路”。There is a long way to go.是存在句型，表示“还有一段很长的路要走”。17.C。Had it not been是if it had not been的倒装形式，意思是“要不是……”。18.A。it作形式宾语，代替后面的-ing形式短语或不定式短语。19.D。It’s no wonder that意为“毫无疑问”，“难怪”。而There is no doubt that意为“毫不怀疑”，“毫无疑问”。20.C。It’s high time that 句型中,that从句应使用虚拟语气。根据dress的用法，应选C。washed和dressed共用助动词were。21.A。第一空为不定式作目的状语，用来回答问句。第二空的主语是what，应用被动意义的to be done. see to it that的意思是“务必使……”，“注意使……”。22.C。该题为强调句型，强调only when引导的时间状语从句。23.A。表示“存在区别”应使用there be句型。24.A。该题包括It takes sb. some time to do sth.这一结构。25.A。符合句型It’s like sb. to do sth.，句意为“只有他才会做与众不同的事。”26.D。stand表示“保持某种状态”，后面接表示状态的形容词作表语，强调状态的延续。27.B。turn意为“变成”“变得”。28.A。此题应选择形容词作sounds的表语。29.B。当表示永久性的或难以扭转的变化时，常用系动词go。30.C。ran wild为固定短语，意思是“放荡不羁”。31.C。smell意为“闻起来”， “有……的气味”，是系动词，后面常跟形容词作表语。32.D。be like表示“看起来像”，可指外貌，也可指内在的品质或特征，但侧重于内在特征；look like侧重于表面特征的相像。33.C。promise用作系动词，表示"有.....可能"，"有希望"。又如：This year promses a good harvest.今年有丰收的希望。34.B。appear意为“显得”。35.C。become作系动词，表示“变成”，其后的单数可数名词前要加a或an. 36.C。remain表示“继续存在”、“仍然处于某种状态”时，为系动词，后跟形容词、介词短语、-ing形式或过去分词。37.B。turn作为系动词时，其后接名词，前不加不定冠词，参见注35。38.C。sound,look,seem,feel作系动词时，后可接like引导的介词短语。39.A。appear,seem,look都可以表示“看起来”，appear强调外表给人的印象，有时含有实质上并非如此的含义；seem则暗示判断有一定根据，而且这种判断往往接近于事实；look强调由视觉得出的印象。40.B。come true是固定搭配，表示“变为现实”。其中come是系动词，表示“成为”，“变得”。41.A。prove为系动词，意思是“被证明是”，其后跟“（to be） ＋形容词﹑名词等”作表语。 42.C。get为系动词，此句意为“天在逐渐变黑。”43.B。taste为系动词，意为“尝起来”，后面跟形容词作表语。44.B。feel为系动词，意为“摸起来”。45.D。fall asleep为固定短语，意为“睡着”。46.B。as if引导的从句经常使用虚拟语气。47.D。It seems that表示“看起来……”，强调根据一定的事实所得出的一种接近于实际情况的判断。48.D。What does sb.／sth. look like 是一个用来询问外部特征的固定句型。49.A。go red with中的go是系动词，意思是“变为”。常常表示“由好变坏”、“由正常变为不正常”的变化。如：go bad (变坏)，go wrong (出毛病)等。此题中的went还可用turned。50.B。stay表示“继续处于某种状态”，其后跟形容词。It用法练习
