朋友你好， 你所说的it 作形式宾语有几种形式： It 代替不定式短语时：（像楼上的一种形式） 1 He feels it his duty to help others （他觉得帮助他人是他的责任。） 2 The new medicine makes it possible to treat this terrible disease （这种新药使治疗这种可怕疾病成为可能。） It 代替动名词短语时： 1 We thought it no use doing that （我们认为那样做无济于事。） 2 Our teacher thinks it no good learning without practice （我们的老师认识光学不实践是没有好处的。） It 代替宾语从句时： 1 I think it very important that we take part in the discussion （我认为我们参加这次讨论是很重要的) 2 Didn't I make it clear to you that I was not coming ( 我不是向你明确表示过我不来了吗？）

在中学英语中，常用 it 替代句子。现对此作一分析和归纳，供同学们学习时参考。

一 it 充当形式主语时，可将真正的主语从句置于句末。

A 谓语动词是被动形式时，常用 it 替代主语从句。例如：

It hasn't been decided whether the meeting will be held

这个会议是否召开，尚未定下来。

B 主句是疑问句或感叹句时，则必须用形式主语 it 替代主语从句。例如：

Is it necessary that she'll come？

她有必要来吗？

How strange it is that the children are so quiet！

孩子们如此安静，真奇怪！

C it 作为形式主语，常出现在下列结构中：

1 It +be+ 形容词＋主语从句。例如：

It's possible that we'll be a little late

我们可能会晚一点儿到。

It was most likely that one third of them lost their lives

他们当中很可能有三分之一的人丧生。

2 It +be ＋分词＋主语从句。例如：

It's surprising that there are so many unhappy marriages

有这么多婚姻不美满，真是令人吃惊。

It is suggested that the task （ should ） be finished in a week's time

有人建议在一周内完成这项任务。

3 It +be+ 名词（短语）＋主语从句。例如：

It's a pity that he isn't here

真遗憾，他没有在这里。

It's a question where we can find this material

我们在哪儿能找到这种材料还是个问题。

4 It + 不及物动词＋主语从句。例如：

It doesn't matter when they'll be back

他们什么时候回来无关紧要。

It happened （ so happened ） that he met his teacher in the street

碰巧他在街上遇到了他的老师。

It seems / appears that someone is knocking at the door

似乎有人在敲门。

二 it 充当形式宾语时，真正的宾语要后置。

A 在 think， make， find， believe， feel， consider， hear 等动词后面跟复合宾语（宾语＋宾语补足语）时，要用 it 作其中的形式宾语。例如：

We think it necessary that you will help him

我们认为你很有必要帮助他。

I felt it a surprise that they were all unfriendly to me

我感到惊奇的是，他们对我都不友好。

注意：若此类动词后面没有形容词或名词作宾语补足语，则一般不用 it 作形式宾语。如不可说： We consider it that you will go there

B like， enjoy， love， hate 等表示“喜怒哀乐”的动词后面跟宾语从句时，可用 it 作形式宾语，而宾语从句要紧跟在 it 之后。例如：

I love it when you sing

我喜欢听你唱歌。

I hate it when she speaks of me

我讨厌她说我。

C 由动词和介词（除 except， but 外）构成的 think of， answer for， depend on， rely on， see to 等短语动词后面，常用 it 作形式宾语，然后再接 that 引导的宾语从句。例如：

I will answer for it that he is honest

我可以担保他是诚实的。

You may depend on it that he will come in time

你可以相信他会及时来到。

三 it 作形式主语时指主句所表示的内容。例如：

1 If it is possible， hold up the part of the body which is bleeding[!--empirenewspage--]

如有可能，就把流血的身体部位抬高。

句中的 it 是指主句 hold up the part of the body which is bleeding if 后面的 it is 常可省略。

2 I would like to see him as soon as it is possible

我想尽快见到他。

此句中只能用形容词 possible ，而不能用副词 possibly 因为 as soon as possible 是 as soon as it is possible 的省略形式。

3 I can discuss the matter with you now， if it is necessary

如有必要，我现在就可以和你讨论此事。

此句中的 if necessary = if it is necessary

四 用 it 指代一个分句乃至整个句子。例如：

1 Tom's mother kept telling him that he should work harder， but it didn't help

汤姆的妈妈喋喋不休地告诉他应该努力学习，但却无济于事。

2 He is over seventy， but doesn't look like it

他已经七十多岁了，可是看起来却不像那么大。

3 John is trying to finish writing his book this month， but he won't find it easy

约翰想在这个月把书写完，不过他会发现这并不容易。

4 I've broken the mirror It can't be helped

我把镜子打破了，这是无法补救的。

5 They won the match after three hours' struggle It wasn't easy， though

他们经过三个小时的拼搏赢得了这场比赛。不过，这是来之不易的。

注意：代替整个句子的 it ，不能用在 know ， remember， try， tell， forget 等动词之后。例如：

1 － The meeting has been put off

－ Yes， I know （不说： Yes， I know it ）

2 － Remember what he told you

－ I'll remember （不说： Yes， I'll remember it ）

3 － Be sure to tell him the news

－ I won't forget （不说： I won't forget it ）

：

1It is+被强调部分+that

该句型是强调句型，将被强调的放在前面，其他部分置于之后，强调的主语如果是人，可以用来替换，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他从句的方法。

It was they that (who) cleaned the classroom yesterday It was in the street that I met her father

It was with great joy ___he received the news that his lost daughter had been found (2004 福建)

A because B which C since D that (D)

2 It is not until +被强调的部分+ that

该句型译成汉语“直到……才”，可以说是的强调形式。It was not until she took off her dark glasses that I realized she was a film star =Not until she took off her dark glasses did I realize she was a film star =I didn’t realize she was a famous film star until she took off her dark glasses

It was ___back home after the experiment (2004 湖北)

A not until midnight did he go

B until midnight that he didn’t go

C not until midnight that he went

D until midnight when he didn’t go (C)

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…

该句型和上一句同属一个句型。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。建议记住该句型中的形容词。

It is important that we (should) learn English well

It is necessary that he (should) remember these words

5 It is said (reported, learned…) that…

该句型中的it 仍是形式主语，真正的主语是that 引导的主语从句。该结构常译为“据说（据报道，据悉……）

It is said that he has come to Beijing

It is reported that another earth satellite has been put into orbit

6 It is suggested (ordered…) that…

该句型和上一句属一个句型。主句中的过去分词是表示请求、建议、命令等词时，that后的从句要用虚拟语气 （should+动词原形）。可以省略，常译为“据建议；有命令……”

It is suggested that the meeting (should) be put off

It was ordered that we (should) arrive there in two hours

7 It is a pity (a shame…) that …

在该句型中，that后的从句一般用虚拟语气（should+动词原形），should可以省去，表示出乎意料，常译为“竟然”。没有这种意义时，则不用虚拟语气。

It is a pity that such a thing (should) happen in your class

这种事竟然发生在你们班上，真是遗憾。

It is a pity that he is ill

他生病了，真遗憾！

8 It is time (about time, high time) that…

该句型中that后的从句应该用虚拟语气，值得注意的是：常用过去时态表示虚拟，有时也用should+动词原形，should 不能省。常译为“是（正是）……的时候……”

It is time that children should go to bed

=It is time that children went to bed

9 It is the first (second, …)time that…

该句型应和上一个句型区别开来。该句型中不用虚拟语气，而用完成时态。至于用哪种完成时态，由主句的谓语动词的时态来决定。如果是一般现在时，从句用现在完成时态；如果是一般过去时，从句则用过去完成时态。该结构中that可以省去；it有时用this替换，常译为“是第一（二,…）次…”。

10 It is …since…

该句型主要用作处理瞬间动词的完成时，要和表示一段时间的时间状语连用。主句中是时间作表语，其时态是现在时和完成时，引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，从句则用过去完成时。

It is (has been) 5 years since his father died

It is almost five years ___we saw each other last time (2005 北京)

A before B since C after D when(B)

该句型主句中的it指时间，主句中的时态常是一般将来时或过去时两种时态，主句中的表语多是long ,not long ,3 days, 2 weeks等表示时间段的词和短语。常译为“…之后才”，“没过……就……”

It was 3 days before he went to Beijing

It will not be long before he finishes his job

13 It happens (seems, looks, appears) that…

该句型中的it 是形式主语，that 引导的是主语从句，主句中的happen, seem等词是不及物动词。

It happened (so happened) that he met his teacher in the street (碰巧……)

It seems that he will be back in a few days (看来……)

The Foreign Minister said, “___our hope that the two sides will work towards peace” (2004北京)

A This is B There is C That is D It is (D)

14 It takes sb…to do sth

该句型中的不定式是真正的主语，是形式主语，句型中的直接宾语是时间。常译为“做……要花费某人……”

It took thousands of people many years to build the Great Wall

15．It is no good (use) doing sth

该句型中的真正主语是动名词短语，主句中的表语可以是 no good (not any good), no use (not any use )

It is no good learning English without speaking English

16 It doesn’t matter whether…

17．It is kind (of sb) to do sth

该句型中的不定式短语是真正主语，如果不定式的逻辑主语是由of引出，主句中的形容词必须是能表示逻辑主语的形容词。常见的有：bad, brave, careless, clever, cruel, foolish good (好心的),honest, horrible, kind, lazy, modest, naughty, nice (有教养的),polite, rude, silly, stupid ,wise ,wrong等。这个句型可以改写为sbis kind to do sth

It is kind of you to stay so =You are kind to say so

18 It is necessary (for sb) to do sth

该句型与上一句统属一个句型。如果不定式的逻辑主语是由for 引出的，主句的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的形容词。常见的形容词有：

Important,necessary,natural,easy,safe,common,,normal,hard,difficult,dangerous,unusual,grape, impossible, pleasant等。

It is important for her to come to the party =It is important that she (should) come to the party

该句型中it 无意义。As if 引导一个状语从句，常译为：“看起来好像……”如果与事实不相符合，则用虚拟语气。

It looks as if he is ill （真的病了）

It looks as if he was ill （事实上没有生病）

It seemed as if he was dying

20 We think it important to learn a foreign language

意为“这是某人第…次做…”，注意time前有序数词，主句是 is 时 ，从句要用现在完成时；如果主句用was ，则从句须用过去完成时。 Eg : It is the third time that I have seen the film

That was the second time that I have been there

IV．It 引导的强调句

强调句形式：It + is/was +被强调的部分+ that/who从句

Eg: It was last week that I met an old friend in the street // It was because he was ill that he didn't come to school yesterday

(强调原因状语从句时，只能强调由because所引导的从句)

判断方法：将It is/was和that去掉，若该句是一个完整无缺的句子即为强调句

常考考点：

①强调句型中的主谓一致Eg: It is you，rather than he，that are to blame for the accident．

②插入从句的强调句型 Eg: It was in the restaurant where we had dinner last Sunday that you left your wallet．

③强调句型的一般疑问句、特殊疑问句形式

一般疑问句：Is / Was it + 被强调部分+ that + 句子其余部分 Eg: Was it in 1933 that the Second World War broke out

特殊疑问句：疑问词+ be + it + that + 句子其余部分Eg: When was it that he changed his mind to take part in the activity？

④强调句型用于名词性从句, 尤其注意要使用陈述语序。

Eg: I don’t know when it was that he changed his mind to take part in the activity？

⑤not until用于强调句型 It is / was not until ＋被强调部分＋ that ＋其他部分

Eg : It was not until midnight that she went back home

此句型只用until，不用till。但如果不是强调句型，till和until可通用。因为句型中It is / was not已经是否定句了，that后面的从句要用肯定句。
