一，it 作形式主语的句式

【句式38】It be a./n. 不定式(形容词-ing词性标注，从句)

【妙句存盘】

1. It is our duty to help the poor. 协助穷光蛋是大家的义务。




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

对大家而言，解出这道题是难以的。

1. It is interesting that you should like him.

你居然喜爱他，简直趣味。

1. It』s no use telling him that. 把这件事情对他说，毫无价值。

【创作点津】

所述词组中的 it全是引导词，作为形式主语，真实的主语分别是句后的不定式、形容词-ing词性标注或从句。

可是假如当家做主语境的不定式短语、形容词-ing分词短语或that-从句过长，则一般 选用本句式，将引导词置放句首，而将真实的主语放置句尾，以防止「上重下轻」的状况。

Exercise 38

Put the following sentences into English.

• 要刘磊更改想法是不易的。 （easy）

• 她居然拒绝了邀约，真令人诧异。 (astonishing)

• 你务必马上考虑。 (necessary)

• 你去探望大家，大家简直十分高兴。 (pleasure)

• 你同他谈一件事，简直混日子。 (waste of time)

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.

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

【妙句存盘】

1. It takes years to master a language. 要熟练一门語言必须两年時间。

2. It took us nine days to finish the work. 进行此项工作中花了大家九天時间。

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

要写本文，他即将花较长的時间。

【创作点津】

本句式表明「干某件事必须(别人)是多少時间」的含意，在其中的 it 是形式主语，替代句后的不定式(to do sth.)。如果不专指花「别人」是多少時间，则 sb.能够省去(见词组1)，不然sb.也不应省掉。句式中的 takes 可依据状况换用其他语态。

Exercise 39

Put the following sentences into English.

1. 我花了一年多的時间学习画画。

2. 徒步去邮政局必须二十分钟上下。

3. 修建这幢房子将必须大半年時间。

4. 坐火车从北京市去天津市大概必须两小时。

5. 她们将花2个月時间来进行此项设计方案。

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.

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

【妙句存盘】

1. It is said that Jim got married a week ago. 听说，托尼一周前结了婚。

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

据报道，大家的军队早已渡江了。

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

(有些人)提议大会推迟举办。

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

(有些人)要求马上派遣医疗组。

【创作点津】

所述词组中的 it 全是形式主语，替代真实主语 that-从句。句中的 「It is said(reported, suggested, requested)...」大致等同于「People say(report, suggest, request)...」的含意。

留意：词组1和词组2 的 that-从句 中的谓语动词用阐述语调，由于从句中上述的可能是客观事实。词组3和词组4 的 that-从句中的谓语动词用虚拟语气「(should) 动词原形」，由于所提议或要求的并不一定成为事实。可以套入此句式的形容词也有：decide, suppose, demanded, ordered, required 等。

Exercise 40

Put the following sentences into English.

1. 听说，大家的新音乐老师很会歌唱。

2. 据信，大家的球队毫无疑问会制胜。

3. 有些人提议大家下周末去协助王大妈。

4. 大伙儿寄希望于这位老教授会来报名参加大家的晚会节目。

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.

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.

【句式41】It seems that-从句/as if-从句

【妙句存盘】

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

来看罗伯特很有可能在此次比赛中获得胜利。

2. It seemed to me(that)we had done something wrong.(= We seemed to have done something wrong.)我好像感觉大家做不对什么事情。

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

来看天快天要下雨。

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

她好像是喝醉酒一样。

【创作点津】

本句式事实上仅仅「主 系 表」构造(S VI P)，在其中的seem 是系动词，后边的 that-从句 或 as if-从句 是表语。本句式中的 it是无人称代词，而并不是形式主语 it。

Exercise 41

Put the following sentences into English.

1. 看上去好像要下雪了。

2. 来看大家沒有取得成功的期待了。

3. 她们的提议看来是有效的。

4. 我好像感觉她们是恰当的。

5. 他看上去好像很疲倦。

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 作形式宾语的句式

【句式42】主语 宾语 it 宾补 不定式/形容词-ing词性标注/从句

【妙句存盘】

1. I found it important to learn spoken English.

我观察学习口语英语十分关键。

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

那里居然有些人住，你很有可能感觉怪异。

3. We thought it no use doing that. 大家觉得做一件事毫无价值。

【创作点津】

本句式归属于六种基本句型之一，即 「主语 及物动词 宾语 宾语补足语」构造。仅仅本句式中的宾语是 it(形式宾语)，其所意味着的真实宾语是句尾的不定式、形容词-ing词性标注或从句。用以本句式的及物动词一般 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语句的主语。如词组1中不定式短语(to learn spoken English)的逻辑主语便是语句的主语「I」。因而，词组1还可以改变成：

I found it important that I learn spoken English.

假如不定式的逻辑主语同语句的主语不一致，则运用不定式复合结构(for sb. to do sth.)，在其中的 sb.便是不定式(to do sth.)的逻辑主语。比如：

I think it necessary for her to learn the violin.= I think it necessary that she should learn the violin. 我觉得她必须学习培训大提琴。

Exercise 42

Put the following sentences into English.

1. 大家觉得每天晚上复习功课是很必需的。

2. 他觉得很怪异，谁都不来报名参加他的生日聚会活动。

3. 我认为探讨这件事情是没什么好处的。

4. 她们的争执使我无法入睡。

5. 爷爷为自己立了一条规定，每日早上六点醒来，进山锻练。

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.

【句式43】It be 被注重一部分 that-从句

【妙句存盘】

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

昨日就是我给爱丽丝五十美金的。

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

昨日我将五十美金交到了阿里。

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

昨日我给爱丽丝的是五十美金钱。

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

我是昨日把五十美金交到阿里的。

【创作点津】

所述词组全是由下边这一非强调句变来的：

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

留意：本句式中的被注重一部分如果是人，则后边可接用that 或who 正确引导的从句；如果是别的內容，如時间、地址、缘故等状语，则后边接用that 正确引导的从句，这时不能用when, where, because 等词来正确引导。总而言之，被注重一部分无论是主语、宾语或状语，都能够用that 正确引导从句。

1. 我要见的是这位主管。

2. 昨日争吵的恰好是她们。
