引导词 it 句型

一,it 作形式主语的句型

【句型38】It+be+a./n.+不定式(动词-ing分词,从句)

【佳句存盘】

1. It is our duty to help the poor. 帮助穷人是我们的责任。

2. It is difficult for us to work out the problem.

对我们来说,解出这道题是很难的。

3. It is interesting that you should like him.

你竟然喜欢他,真是有趣。

4. It』s no use telling him that. 把这件事告诉他,毫无用处。

【写作点津】

上述例句中的 it都是引导词,用作形式主语,真正的主语分别是句后的不定式、动词-ing分词或从句。

但是如果作主语用的不定式短语、动词-ing分词短语或that-从句太长,则通常采用本句型,将引导词放置句首,而将真正的主语置于句尾,以避免「头重脚轻」的现象。

Exercise 38

Put the following sentences into English.

  • 要刘磊改变主意是不容易的。 (easy)

  • 她竟然拒绝了邀请,真让人惊讶。 (astonishing)

  • 你必须立即出发。 (necessary)

  • 你来看望我们,我们真是非常高兴。 (pleasure)

  • 你同他谈那件事,真是浪费时间。 (waste of time)

参考答案

  • It』s not easy for Liu Lei to change his mind.

  • It』s astonishing that she should refuse the invitation.

  • It is necessary for you to start right now.

  • It』s a great pleasure that you come to visit us.

  • It』s a waste of time that you talk to him about that.

【句型39】It takes sb. some time to do sth.

【佳句存盘】

1. It takes years to master a language. 要精通一门语言需要几年时间。

2. It took us nine days to finish the work. 完成这项工作花了我们九天时间。

3. It』ll take him a long time to write the article.

要写这篇文章,他将要花很长的时间。

【写作点津】

本句型表示「干某事需要(某人)多少时间」的意思,其中的 it 是形式主语,代替句后的不定式(to do sth.)。如果不特指花「某人」多少时间,则 sb.可以省略(见例句1),否则sb.就不应省去。句型中的 takes 可根据情况换用别的时态。

Exercise 39

Put the following sentences into English.

  1. 我花了一年多的时间学习绘画。

  2. 步行去邮局需要二十分钟左右。

  3. 建造这幢房屋将需要半年时间。

  4. 乘火车从北京去天津大约需要两小时。

  5. 他们将花两个月时间来完成这项设计。

参考答案

  1. It took me more than a year to learn drawing.

  2. It takes about twenty minutes to walk to the post office.

  3. It』ll take half a year to build the house.

  4. It takes about two hours to go from Beijing to Tianjin by train.

  5. It』ll take them two months to finish the design.

【句型40】It is said(suggested, etc.)+that-从句

【佳句存盘】

1. It is said that Jim got married a week ago. 据说,吉姆一周前结婚了。

2. It was reported that our troops had crossed the river.

据报道,我们的部队已经渡江了。

3. It is suggested that we should put off the meeting.

(有人)建议会议延期召开。

4. It is requested that a medical team be sent immediately.

(有人)请求立即派出医疗队。

【写作点津】

上述例句中的 it 都是形式主语,代替真正主语 that-从句。句中的 「It is said(reported, suggested, requested)...」大体相当于「People say(report, suggest, request)...」的意思。

注意:例句1和例句2 的 that-从句 中的谓语动词用陈述语气,因为从句中所述的可能是事实。例句3和例句4 的 that-从句中的谓语动词用虚拟语气「(should)+动词原形」,因为所建议或请求的并不一定成为事实。能够套用此句型的动词还有:decide, suppose, demanded, ordered, required 等。

Exercise 40

Put the following sentences into English.

  1. 据说,我们的新英语老师很会唱歌。

  2. 据信,我们的足球队肯定会取胜。

  3. 有人建议我们下星期天去帮助王大妈。

  4. 大家指望那位老教授会来参加我们的晚会。

  5. 已经决定张先生是主要发言人。

参考答案

  1. It is said that our new English teacher is good at singing.

  2. It is believed that our football team will certainly win.

  3. It is suggested that we(should)go to help Grandma Wang next Sunday.

  4. It was expected that the old professor would come to join us in the evening party.

  5. It has been(was)decided that Mr Zhang be the main speaker.

【句型41】It seems+that-从句/as if-从句

【佳句存盘】

1. It seems that John will win the race.(= John seems to win the race.)

看来约翰可能在这次竞赛中获胜。

2. It seemed to me(that)we had done something wrong.(= We seemed to have done something wrong.)我似乎觉得我们做错了什么事情。

3. It seems as if it is going to rain.(= It seems to rain.)

看来天快要下雨了。

4. It seemed as if she were drunk.(= She seemed to be drunk.)

她好像是喝醉了似的。

【写作点津】

本句型实际上只是「主+系+表」结构(S+VI+P),其中的seem 是系动词,后面的 that-从句 或 as if-从句 是表语。本句型中的 it是无人称代词,而并非形式主语 it。

Exercise 41

Put the following sentences into English.

  1. 看起来似乎要下雪了。

  2. 看来我们没有成功的希望了。

  3. 他们的建议看来是合理的。

  4. 我似乎觉得他们是正确的。

  5. 他看起来似乎很疲乏。

参考答案

  1. It seems(looks, appears)as if it is going to snow.

  2. It seems that we have no hope of success.

  3. It seems that their suggestions are reasonable.

  4. It seemed to me that they were right.

  5. It seems(looks, appears)as if he is very tired.

二,it 作形式宾语的句型

【句型42】主语+谓语+it+宾补+不定式/动词-ing分词/从句

【佳句存盘】

1. I found it important to learn spoken English.

我发现学习英语口语非常重要。

2. You may think it strange that anyone would live there.

那儿竟然有人住,你可能觉得奇怪。

3. We thought it no use doing that. 我们认为做那件事毫无用处。

【写作点津】

本句型属于六种基本句型之一,即 「主语+及物动词+宾语+宾语补足语」结构。只是本句型中的宾语是 it(形式宾语),其所代表的真正宾语是句尾的不定式、动词-ing分词或从句。用于本句型的及物动词通常是:consider, feel, find, make, think等。

用不定式作形式宾语时,不定式的逻辑主语也就是句子的主语。如例句1中不定式短语(to learn spoken English)的逻辑主语就是句子的主语「I」。因此,例句1也可以改写成:

I found it important that I learn spoken English.

如果不定式的逻辑主语同句子的主语不一致,则应用不定式复合结构(for sb. to do sth.),其中的 sb.就是不定式(to do sth.)的逻辑主语。例如:

I think it necessary for her to learn the violin.= I think it necessary that she should learn the violin. 我认为她有必要学习小提琴。

Exercise 42

Put the following sentences into English.

  1. 我们认为每晚复习功课是很必要的。

  2. 他感到很奇怪,谁也不来参加他的生日聚会。

  3. 我觉得讨论这件事是毫无益处的。

  4. 他们的争吵使我没法睡觉。

  5. 祖父给自己立了一条规矩,每天早晨六点起床,上山锻炼。

参考答案

  1. We consider it necessary that we should review our lessons every evening.

  2. He felt it strange that no one came to his birthday party.

  3. I feel it no good discussing the matter.

  4. Their quarrel made it impossible for me to sleep.

  5. Grandpa made it a rule for himself to get up at six in the morning and go to the hill to take exercise.

【句型43】It+be+被强调部分+that-从句

【佳句存盘】

1. It was I that(who)gave Alice 50 dollars yesterday.

昨天是我给爱丽丝五十美元的。

2. It was Alice that(who)I gave 50 dollars yesterday.

昨天我把五十美元交给了爱丽丝。

3. It was 50 dollars that I gave Alice yesterday.

昨天我给爱丽丝的是五十美元钱。

4. It was yesterday that I gave Alice 50 dollars.

我是昨天把五十美元交给爱丽丝的。

【写作点津】

上述例句都是由下面这个非强调句变来的:

I gave Alice 50 dollars yesterday. 我昨天给爱丽丝五十美元钱。

注意:本句型中的被强调部分如果是人,则后面可接用that 或who 引导的从句;如果是其他内容,如时间、地点、原因等状语,则后面接用that 引导的从句,此时不能用when, where, because 等词来引导。总之,被强调部分不论是主语、宾语或状语,都可以用that 引导从句。

Exercise 43

Put the following sentences into English.

  1. 我想要见的是那位经理。

  2. 昨天吵架的正是他们。

  3. 我拾到这个钱包是在去学校的路上。

  4. 杨晓莲昨夜遗失的正是这条项链。

  5. 格林先生到达这座城市正是几天以前。

参考答案

  1. It is the manager that(who)I want to see.

  2. It was they that(who)quarrelled yesterday.

  3. It was on the way to school that I picked up the wallet.

  4. It was this necklace that Yang Xiaolian lost yesterday evening.

  5. It was several days ago that Mr Green arrived in the city.
