一般说来，定语从句被分割开来大致有以下三种：

①在先行词与定语从句之间插入一个状语。

如：There are many thousands of stars in the sky that are like the sun.

在太空中有成千上万的象太阳般的星星。

乍一看，that引导的定语从句在名词sky的后面，似乎应该是修饰sky的。但仔细一想，”不对啊，天空怎么能象太阳呢？“，原来that引导的定语从句被in the sky这个地点状语分隔开来，修饰中心词stars。

②在先行词与定语从句之间插入一个定语。

如：Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace?

你还记得吗，十年前的一天下午，我来到你家，找你借了一条钻石项链？

when I came to your house and borrowed a diamond necklace实际上是修饰afternoon而不是修饰 years。ten years ago 实际上是定语后置修饰afternoon。

③先行词与定语从句被谓语分隔开来。此时，先行词通常是句子的主语，因定语从句较长，主句谓语较短，为使句子平衡，常将定语从句移至谓语之后如：A new master will come tomorrow who will teach you German.

明天，新（男）老师将来较你德语。

【语法难点精析之besides,but,except,exept for,excepting,apart from的区别】

（１） besides与except

前者表示＂除．．．以外，还有．．．＂；后者表示＂从整体中除去．．．＂

这个大家都知道，就不举例子了．

（２）except与except for

a．除去的和非除去的是同类事物，用except

eg：

All the essays are well written except Nelson"s.

Nelson的文章（除去的）和All the essays（非除去的）是同类事物，所以用except．

b．除去的和非除去的不是同类事物，用except for，并且从语气上通常表示遗憾．

eg：His essay is well written except for a few spelling mistakes.

a few spelling mistakes(除去的）和His essay（非除去的）是不同类的事物．

（３）apart from 具有多重意义：既可表示besides，也可以表示exept或exept for，还可以表示without的意思

eg：

Apart from the cost,it will take a lot of time.(=besides)

The orphan had no one to take care of him apart from his uncle.(=except)

He has done good work,apart from a few slight faults.(=except for)

There can be no knowledge apart from practice.实践出真知．（＝without）

（４）excepting =except,但一般用于句首或用于not，without，always等词之后

eg:

Excepting his brother,they are all right.

Everyone,not excepting myself,must share the blame.

All of us,without excepting those who know more about the subject,should study.

All my brothers com here every day,always excepting the youngest.

（５）but与except同义，但but多用在every，any，no等和由这些词构成的复合词如everything，anywhere，nobody等词以后及all，none之后

eg：

The children go to school everyday but Sunday.

They are all gone but me.

You can get the book anywhere but here.

There is no one but me.

Who but George would do such a thing?

【语法难点之too...to 结构表示肯定含义的情况】（连载中）

【too...to 结构表示肯定含义的情况】

我们知道too...to结构一般表示否定含义,意为"太...以致于不能"

eg:He is too old to work.

但too...to在下列情况下却表示肯定含义:

⑴当too前或to前有否定词构成双重否定时.

eg:English is not too difficult to learn.

英语并不太难学.

He is too wise not to see that.

他很聪明,不会不懂这一点.

⑵当too后是glad,pleased,happy,delighted,satisfied,ready,willing,kind,apt,good,true,easy,

near,careful,well,early,delicious,eager,anxious等形容词或副词时.

eg:They are too anxious to leave.

他们急于离开.

He is too ready to help others.

他总是乐于助人.

与这些词连用时,too前还常加上only,all,but,just,simply等副词,意思不变,因为这些词加上too后与very同义.

eg:I"m only too glad to see you .

见到你非常高兴.

They are but too pleased to hear the news.

他们听到这个消息,非常高兴.

⑶与cannot连用时.

eg:You cannot be too careful(=You can never be careful enough) to do your homework.

你做作业越仔细越好(=无论怎样仔细也不过分).

⑷当不定式在句中作定语或真正的主语时.

eg:There are too many problems to be solved.

有很多问题有待解决.

It is too much to say that he is a fool.

【语法难点精析之every表示”每隔“的用法】

⑴"every other+单数名词”

意思是“每隔一。。。”

如：every other day 每隔一天 every other tree 每隔一棵树

⑵“every+基数词+复数名词”或“every+序数词+单数名词”

意思是“每隔。。。”（较英语数词少一个）

如：every three days=every third day 每隔两天（或者译为每三天）

因此every two days=every other day 每隔一天（或者译为每两天）

⑶“every few+复数名词”

意思是“每隔几。。。”

如：every few days（每隔几天）

【语法难点精析之alive、live、living和lively的用法】

⑴ lively 有“活泼的、快活的、生动的”等意思，可以指人或物，可作定语或标语；但它没有“活着的”意思，而其他三个都有。

如：

Young children are usually lively.

小孩子们通常是活泼的。

He told a very lively story.

他讲了一个生动的故事。

⑵alive、live、living都有“活的、有生命的”意思，与dead意义相反。但live通常只作前置定语，且一般用于动物；alive、living不仅可作定语（alive只能置于名词后；living一般置于名词前，也可置于名词后），也可以作表语。

如：

This is a live(=living) fish.(=This is a fish alive.)

这是一条活鱼。（指动物，且作定语时，三者均可用）

Who"s the greatest man alive(=living man)?

谁是当今最伟大的人物？（指人，不能用live）

The fish is still alive(=living)

那条鱼还活着。（指动物作表语时不能用live）。

⑶living主要指在某个时候是活着的，而alive指本来有死的可能，但仍活着的。而且，作主语补足语或宾语补足语时，只能用alive；作比喻义（如“活像。。。”、“活生生的”等）解时，要用living。

如：

The enemy officer was caught alive.(作主语补足语，不用living）

那位敌方军官被活捉了。

We found the snake alive.(作宾语补足语，不用living）

He is the living image of his father.(比喻义，不用alive）

他活象他父亲。

⑷只有living前加the方可表示“活着的人”，作主语时，视作复数。

如：

The living are more important to us than the dead.

活着的人对我们来说比死去的人更重要。

虚拟语气的重点是：

1．一些常见的虚拟语气的句型或结构。

2．虚拟语气的特殊形式，即用来表示要求、建议、命令、提议、意愿等的主语从句、宾语从句、表语从句和同位语从句中的虚拟形式。

3．主从句表示不同的时间概念、事实或假设情况，从而交错成为复合虚拟语气。

4．含蓄条件句中的虚拟语气的表示愿望的虚拟形式。

  上述四个要点往往在完形填空或者阅读理解里面存在，尤其是每年完形填空都至少有一道直接考这方面的知识的题目，而在阅读理解里，我们掌握上述四个重点对于我们理解文章的大意和作者态度很有帮助，了解哪些观点是作者假设的、虚拟的，哪些是真实的，这样对于我们回答关于作者态度观点题很有帮助。

下面我们将主要从上述四个方面来重点论述在考试中应该注意的问题。

一、虚拟语气的常见类型和句型

（1）由wish引起的表示愿望的虚拟语气

A．用wish表示对现在的愿望时，它所引起的宾语从句中谓语动词形式为：过去式（be动词用were）。

B．用wish表示对将来的愿望时，它所引起的宾语从句中谓语动词形式为：would, could, might+ 动词原形。

C．wish用于对过去的事实表示一种不可能实现的愿望时，宾语从句中的谓语动词形式为：had+动词过去分词或could, would + have +动词过去分词。

The picture exhibition bored me to death; I wish I had not gone to it.

---“I let Joe borrow our radio for the afternoon.”

---“That’s all right, but I wish he would buy one of his own.”

I wish that he weren’t so lazy.

(2)had hoped引起的宾语从句中备用语动词形式为would+动词原形，表示一种过去未实现的愿望或令人失望的事。

His father had hoped that his son would go to business with him, but his son became an artist later.

(3)would (had) rather, would as soon, would sooner和would prefer所引起的从句中要求用过去式表示当时或将来的情况，用过去完成时表示过去的情况，表示希望或婉转的责备。例如：

I’d rather you posted the letter right away. 我倒希望你把这封信立刻寄出去。

I would prefer he didn’t stay there too long.我倒希望他不要在那儿可得太久。

I would just as soon you had returned the book yesterday.我真希望你昨天把这本书还了。

（4）It’s (high, about) time that 句型中that从句中要求用虚拟语气形式，即动词要用过去式。

It’s time that something was done about the traffic problem downtown.

It is high time that we put an end to this discussion.现在是我们该结束讲座的时候了。

（5）as, 或者whether…or…谓语多用be的原形，引导让步虚拟从句，这种用法通常采用倒装结构：

Church as we use the word refers to all religious institutions, be they Christian, Islamivc, Buddhist, Jewish, and so on.

The business of each day, be it selling goods or shipping them, went quite smoothly.

（6）由连接词in case, so that ,unless, lest ,for fear that引起的状语从句中，谓语动词要用虚拟形式，即should(might, would)+动词原形，例如：

She put a blanket over the baby for fear that he should catch cold. 她在那个婴儿身上盖上了毯子以免他着凉。

The bad man was put in the soft-padded cell lest he injure himself.

(7) if it were not for…与现在事实相反， if it had not been for与过去事实相反，两个都相当于but for：

If it had not been for his help(=but for his help),we would not have succeeded.

(8) 虚拟语气用于as if（though）引起的方式状语从句和表语从句中，其动词形式与wish宾语从句的形式相同。例如：She often laughs spontaneously, and her good humor breaks out as brightly as if it were a part of the sunshine above.她常常发出发自内心的微笑，而且她那美好的情绪像天上一道明亮的阳光一样，常常流露出来。

They talked as if they had been friends for years.他们交谈着，就好像他们是我年的老朋友一样。

She looks as if she would cry.她看起来好像要哭了。

(9)其它各种句型, as though, suppose, had rather, supposing, if only等等

If I were in a movie, then it would be about time that I buried my head in my hands for a cry.

二、特殊形式的虚拟语气

虚拟语气的特殊形式，即用来表示要求、建议、命令、提议、意愿等的主语从句、宾语从句、表语从句和同位语从句中的虚拟形式，其虚拟语气的构成往往是由should(可省略)+动词原形that从句。

A、 用于表示意愿、建议、命令、提议、请求等动词后的that宾语从句中，这类动词有：

ask要求 advise建议 arrange安排 beg请求

command命令 decide决定 demand要求 desire渴望

determine决定 insist坚持 intend打算 maintain坚持主张

move建议，动员 propose提议 object反对 order命令

prefer建议 require 需要 request要求 resolve下决心

recommend推荐 suggest建议 stipulate约定，规定 urge强调，促进

vote公认，提议 decree颁布（法令） pray请求

注意：这类动词后面除了可接that虚拟句以外，也可以接doing或者to do…来表达，一般情况下，意思没有什么差别。

She advised that we should keep the gate locked.（书面体）

She advised us to keep the gate locked.（口语）

She advised keeping the gate locked.(较随便)

B、用于It is+形容词或过去分词+主语从句中，这类形容词或分词有：

advisable合理的 decided决定的 crucial关键的 appropriate恰当的

determined决定的 commanded命令的 arranged安排的 essential紧要的，基本的

complied遵照 anxious焦急的 imperative迫切的 important重要的

desirable合意的 better较好的，更好 insistent坚持的  desired想要

asked请求keen渴望的 incredible难以置信的 adamant坚定不移的

natural自然的  insisted坚持  necessary必要的 suggested建议

urgent紧迫的  ordered命令  shocked震惊的 vital极其重要的

possible可能的 strange 奇怪的 preferable （好一点） proposed提议

requested要求的  required要求的  recommended推荐 resolved决定的

probable（可能的） pity可惜，憾事 shame遗憾

注意：这类形容词后面除了可接that虚拟句以外，也可以for…to do…

来表达，一般情况下，意思没有什么差别。

It is essential that he should be prepared for this.

It is essential for him to be prepared for this.

C．用于由表示建议、要求、命令、请示等含义的名词引导的表语从句和同位语从句中，这类名词常见的有：

advice忠告  decision决定  demand要求  desire要求、愿望

insistence坚持  motion提议  necessity必要性 order命令

preference偏爱 proposal提议  pray恳求  recommendation推荐

request要求  requirement要求  resolution决心 suggestion劝告、忠告

例如：

This is their resolution that extra-curriculum activities be made part of their school life.这是他们的决议：要使得课外活动成为他们学校生活的一部分。

The motion that the remark of the last speaker be expunged from the record.该提议要求把最后一个发言的人的讲话从记录上除掉。

三、混合虚拟语气

  有时主句和从句的谓语动词指不同的时间，这时需要用混合虚拟语气。一般来说，在这种情况下，主从句谓语动词指代的时间不同，所以我们又可以错综时间条件句，在这种虚拟情况，动词形式应根据实际情况灵活使用，在做这些题目时候尤其要注意每道题目的提示语：时间状语。绝大多数情况下，从句或者主句都有相关的时间状语，这是我解题的关键。

If you  that late movie last night, you wouldn’t be so sleepy.

A. haven’t watched B. didn’t watch

C. hadn’t watched  D. wouldn’t have watched  答案选C。

Many dead would now be alive if they have not attempted to return for something.

Had Paul received six more votes in the last election, he would be our chairman now.

  混合虚拟语气还有一种情况就是事实和虚拟假设的混合句，这样的句子不仅仅是时间的不同，而重要是事实和假设的混合。

I would have gone to visit him in the hospital had it been at all possible, but I was fully occupied the whole of last week.

该句前半部分是假设虚拟，而后半部分是事实的陈述。

Your math instructor would have been happy to give you a make-up examination had you gone and explained that your parents were ill at the time.

  该句前半句用的是假设虚拟，后半句主句也用的是假设虚拟（如果你去并且解释的话），但是后半句的从句用的是事实语气，因为“父母病了”是客观事实，故不需要用虚拟形式had been。

四、含蓄虚拟条件句

  含蓄条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常来表示含蓄虚拟条件的手段有：

（1）介词或介词短语，如but for, but that, without, in case of, under more favorable condition等。

  the leadership of the party, we could not be living a happy today.=If there hadn’t been the leadership of the party, we could not be living a happy today.

A. In spite of B. But for C. Because of D. As for  答案选B。

But that she was afraid, she would have said no.

(2)连词，如：so that, unless, in case, supposing, lest, provided(倘若……)，for fear that(唯恐)，in order that, on condition that, if only(要是……就好了)等。

She listened carefully in order that she might discover exactly what he wanted.=if she listened carefully ,she might discover exactly what he wanted.

If only I had more money, I could buy a car.

  (注：lest, for fear that 和 in case 引起的从句中谓语动词多用should+动词原形，但可以不用虚拟语气，而用动词的陈述语气形式。)例如：

  The foreign teacher spoke slowly in case we misunderstood him. 这位外籍教师说得很慢以免我们听不懂。

Care must be taken in using this method lest overflow should occur.在使用此法时要小心谨慎，以免会发生溢流现象。

（3）通过上下文及内在含义，句中往往有but, otherwise, unfortunately等类似转折词。

I thought the children when we returned home, but they were still awake.

A. were sleeping B. would be sleeping C. had been sleeping nbsp; D. would sleep选择 B。

(4)形容词及其比较级

A more careful person would not have made so many mistakes.

A less conscientious man wouldn’t have tried so hard to get this job done.

(5)分词短语

Having known in time, we might have prevented the accident.

Born ten days earlier, the boy could have seen his late father.

(6)动词不定式短语。一般intended/meant/hoped/wished/planned 或 was/were+不定式完成式或had intended/meant/planned/hoped/wished/+不定式一般式表示虚拟。

I intended I should call on you, but I was busy at that time.

To hear him speak French, you would take him for an Englishman.

She would be stupid not to accept his invitation.

It would be easier to do it this way.

(7)名词短语和名词+and结构

A judicious man would not have committed suicide.

A diligent student would have worked harder.

(8)独立主格结构

All things considered, the price would be reasonable.

(9)定语从句

Anyone who had been in your position would have done the same.

A nation, which stopped working, would be dead in a fortnight.

(10）情态动词完成式暗示虚拟语气：

I should have called to make an airline reservation, but I didn’t.

The porter ought to have called the fire-brigade as soon as he saw the fire in the stock, which went up in smoke.

(11)动词原形表示虚拟

动词原形直接用在句子中也被看作是一种虚拟，最常见于正式文体中，动词原形一般用在条件从句中，有时倒装置于句首，同时这种用法也常见于独立句中表达愿望。

God bless you!

All magnets behave the same, be they large or small.

She’ll be sixteen years odd, com May.(come May =when May come).

If that be so, we shall take action at once.

答案与详解

1．A．条件句表示与现在事实相反的虚拟。

2．B．条件句表示与过去事实的虚拟。

3．A．条件句表示与未来事实的虚拟。

4．B．条件句表示与未来事实的相反。

5．C．条件句表示与现在事实的虚拟。

6．D．条件句表示与现在事实的虚拟。

7．B．这个句子中含有一个省略if，把助动词提前到主语they之前的虚拟条件句，该条件句表示对过去情况的假设，而主句中by the time they were finished 表明主句也应该是对过去发生的情况的假设，因而应该选（B）would have lost为正确答案。

8．（D）这道题目是一个混合虚拟语气的句子。条件句省略了if，把助词had提前到主语前面，表示对过去情况的假设，而主句中now表明了对现在情况的假设，所以应选would(should, could, might)+动词原形这种表达形式。四个选项中只有（D）是正确表达形式，故为正确答案。

9．（D）until recently，因此（D）是正确答案，而主句是隐含的对现在情况的假设，该句是一个混合虚拟条件句。

10．（B）假设的情况有时不是用一个条件句表示，而是隐含在一个由介词如but for、but that、without, 由连词but、副词otherwise 、比较级、形容词、独立主格等表示的上下文中。本句主句表示对过去情况的假设，但事实上由于英语考试而没有去成，即若不是因为英语考试，我本可以去听音乐会，所以应选But for为正确答案。

11．（C）题目中的第一句话表示的是现在真实的情况，而第二句话中所要表达的是应该做但事实上没有做的事，这种情况导致第一句话中真实情况的发生，故If only条件句假设的是过去一种情况，因此应该用had +过去分词，所以正确答案是（C）。

12．D．注意主句now表示现在的时间状语，所以主句是对现在虚拟，从句是对过去虚拟。

13．A．从句对过去的虚拟。

14．B．从句表示虚拟，而主句是事实。

15．（D）it是形式宾语，urgent是宾语补足语，that引导的从句是真正的宾语从句，该从句的内容被认为是urgent（急迫的），这样从句的谓语动词要求用虚拟语气形式，即should（可以省略）+动词原形。因此，本题正确答案是（D）。

16．（C）在表示要求、愿望、建议、请求、命令等含义的名词同位语从句中，从句谓语动词要用虚拟语气形式，即should(可以省略)+动词原形。

17．（D）本道题目的前半句话是对过去情况的一种假设，但事实上并没有发生，而事实上没有发生的真实原因是句子的后半部分由but引导的转折句所表述的真实。因而but所引导的句子中应该用表示志过去事实相符合的表陈述的时态，即一般过去时。

18．（B）此题要求在if从句中选择适当的动词形式，以主句中的动词apologize(抱歉)来看，if从句中表达的内容应该是过去做的事，因此可以排除（A），因为（A）是现在时。（C）中should+have+过去分词结构表示本来应该做却没有做的事，在此不合题意。（D）选项中的might+have+过去分词表示对过去发生的事情很不肯定的猜测，它表达的内容还不能成为事实，所以藉此道歉真是不知从何说起，因此此处也不合题意。（B）had offended表示当时已经发生了的动作。这是复杂条件句：apologize 是现在，而条件句是表示对过去假设的条件句。

19．（A）该句也是一个复杂条件句（或称作混合虚拟条件句）。条件句表示对过去情况的假设，而主句表示对现在情况的假设，但事实上却与此相反，所以正确答案应该是（A）。

20．（A）as if引导的从句要求用虚拟语气，表示同时或将来的情况，动词要用过去式（be动词用were）或would(could等)+动词原形，本句话中指的是当时的情况，所以要用过去式，故（A）是正确答案。

21．D．

22．D．

23．C．

24．A．

25．D．

26．（B）had not occurred表示对过去的虚拟，条件句中要用过去完成式，主句中要用should(would, could, might)+动词原形的过去分词。

27．（B）had hoped是常见的要求其后的宾语从句用虚拟语气的句型,虚拟语气would+动词原形。

28．（C）表示对过去情况的假设，主句动词形式为would(should, could, might)+have+过去分词，条件句为过去完成式，if可以省略，但要把had提前主语前面。（B），（D）的表达不符合英语表达习惯，所以（C）是正确答案。

29．（A）suggest后面的从句要用虚拟语气形式，其形式为should（可以省略）+动词原形。

30．A．表示与现在相反的虚拟。

31．A．as though引导的与过去相反的虚拟。

32．D．felt是过去式，所以该句是由as though引导的与过去相反的虚拟。

33．D．as if引导的与现在事实相反的虚拟。

34．A．as if引导的与过去相反的虚拟。

35．C．

36．（D）would rather后接从句要求用虚拟语气，形式为过去式，表示对现在或将来的假设，或为过去完成式表示对过去的情况的假设。

37．（C）who引导的定语从句中的现在完成时表示动作业已发生，所以主句中表示的虚拟是针对已经发生了的行为，所以应该用过去完成式表示对过去的虚拟。

38．（B）

39．（C）这是一人含蓄虚拟条件句，通过介词短语without,表示潜在的一种假设，而主句中的情况也早已经发生，所以是对过去情况的一种假设，因此用would not have been achieved这一形式。

40．（D）连so that引导的从句中要求用虚拟语气，表示一种假设，形式为might+动词原形。

41．（B）It is time that是一种要求从句用虚拟语气的常见句型。虚拟语气形式为动词的过去式。

42．（C）

43．（C）otherwise用来表示一种含蓄的虚拟假设，因为是对过去(yesterday)的情况的假设，所以应该用would have come形式。

44．（B）所给的四个选项中没有一个表示对未来的情况的虚拟的形式should+动词原形，或是were to do，因此可以断定if引导的条件句在这里最真实的条件句，用一般现在时表示一般将来时，故（B）是正确答案。

45．（A）这是一个混合虚拟语气的句子，if条件句表示的是对过去情况的假设，而主句是对现在（now）的情况的假设，故用would tell形式。

46．C．

47．C．

48．C．

49．B．would rather引导的虚拟语气其谓语用过去式。

50．D．would as soon引导的虚拟语气，其谓语动词也用过去式.

51．B．

52．B．

53．B．

54．B．

55．C．注意单词otherwise引导虚拟语气。

56．C．同上。

57．A．注意词组for fear that

58．A．注意without

59．C．

60．C．

61．D．

62．B．

63．D．

64．A．

65．D．

非谓语动词主要包括不定式、动名词和现在分词。为了区分这三种不同的非谓语动词的用法和含义，我们将分别从三种非谓语动词在句子中做主语、宾语、宾语补足语、定语、状语、

表语以及一些特殊结构句型等角度来区分其用法和细微含义。

  1．不定式和动名词作主语的区别

  (1)动名词作主语通常表示抽象动作；而不定式作主语表示具体动作。

  Smoking is prohibited(禁止)here．这里禁止抽烟。(抽象)

  It is not very good for you to smoke so much．你抽这么多烟对你身体很不好。(具体)

  (2)动名词作主语时，通常用以表示一件已知的事或经验。

  不定式短语通常用来表示一件未完成的事或目的。

  Climbing mountains is interesting．爬山很有趣。(经验)

  Driving a car during the rush hour is tiring．在高峰时刻开车令人厌烦。(经验)

  （3）不定式做主语，一般用it当形式主语，把作主语的不定式短语后置。

  It took me only five minutes to finish the job.

  2．不定式、动名词和分词作表语的区别

  (1)不定式作表语

  1)不定式作表语一般表示具体动作，特别是表示将来的动作。

  To do two things at a time is to do neither．--次做两件事等于未做。

  What I would suggest is to start work at once.我的建议是立刻开始干。

  2）如果主语是不定式（表示条件），表语也是不定式（表示结果）。

  To see is to believe.百闻不如一见。

  To work means to earn a living．工作就是为了生活。

  3)如果主语是以aim，duty，hope，idea，happiness，job，plan，problem，purpose，thing，wish等为中心的名词，或以what引导的名词性从句，不定式作表语是对主语起补充说明作用。

  His wish is to buy a luxurious car in the near future．他的希望是在不远的将来买一辆豪华轿车。

  The function of Louis Sullivan’s architecture was to provide large uninterrupted floor areas and to allow ample light into the interior.

The most important thing is to negotiate with them about the future of the plant．

  (2)动名词作表语：动名词作表语，表示抽象的一般性的行为。

Our work is serving the people．我们的工作是为人民服务。

His hobby is collecting stamps．他的爱好是集邮。

(注)动名词作表语时与进行时态中的现在分词形式相同，但其所属结构迥异，进行时态说明动作是由主语完成的。动名词做表语，说明主语的性质或情况。

People cannot but feel puzzled，for they simply cannot understand how he could have made such a stupid mistake.

  His victory in the final was no more convincing than I had expected．

  (3)分词作表语

  分词做表语有两种情况，一种是现在分词做表语，一种是过去分词做表语，这两者区别是考试中经常考到的地方。一般来说，表示心理状态的动词如excite，interest等都是及物动词，汉语意思不是“激动”，“高兴”，而是“使激动”、“使高兴”，因而现在分词应该是“令人激动的”、“令人高兴的”，过去分词则是“感到激动的”和“感到高兴的”。所以，凡表示“令人……的”都是-ing形式，凡是表示“感到……”都用-ed形式。换句话说，若人对……感兴趣，就是somebody is interested in...,若人/物本身有兴趣时，就是说**./sth. is interesting.这类词常见的有：

  interesting使人感到高兴--interested感到高兴的

  exciting令人激动的--excited感到激动的

  delighting令人高兴的--delighted感到高兴的

  disappointing令人失望的--disappointed感到失望的

  encouraging令人鼓舞的--encouraged感到鼓舞的

  pleasing令人愉快的--pleased感到愉快的

  puzzling令人费解的--puzzled感到费解的

  satisfying令人满意的---satisfied感到满意的

  surprising令人惊异的--surprised感到惊异的

  worrying令人担心的--worried感到担心的

  Travelling is interesting but tiring．旅行是有趣的，但是使人疲劳。

  The pupils will get confused if they are made to learn too much．如果要学生学得太多，他们会感到糊涂的。

  The argument is very convincing．他的论点很令人信服。

  They were very excited at the news．听到这个消息，他们非常激动。

  3．不定式和动名词作宾语的区别

英语中大多数动词既可跟不定式，也可跟动名词作直接宾语，但有些动词要求：

(1)不定式做宾语和宾语补足语

  1)下面的动词要求不定式做宾语

  attempt企图 enable能够 neglect忽视

  afford负担得起 demand要求 long渴望

  arrange安排 destine注定 mean意欲，打算

  begin开始 expect期望 omit忽略，漏

  announce宣布 force强迫 press迫使

  bride 收买 inspire鼓舞 request请求

  cause引起 instruct指示 require要求

  deserve应受 leave使，让 tell告诉

  entitle有资格 order命令 warn告诫

  enable使能够 need需要 urge激励，力说

  encourage鼓励 oblige不得不 want想要

  condemn指责，谴责 lead引起，使得 teach教

  entreat恳求 permit允许 wish希望

  (2)有少数动词只能用动名词作宾语

  acknowledge承认，自认 cease 停止 mention说到，讲到

admit 承认 tolerate忍受 dislike不喜欢，讨厌

advocate：提倡，主张 complete完成 dread可怕

appreciate 感激，欣赏 confess坦白 endure忍受

avoid避免 contemplate细想 enjoy享有，喜爱

bear忍受 defer拖延 envy嫉妒

can’t help不禁 delay延迟 escape逃跑，逃避

can’t stand受不了 deny否认 excuse借口

hate讨厌 prevent阻止 save营救，储蓄

keep保持 quit放弃停止 stand坚持，忍受

loathe非常讨厌，厌恶 recall回想

例如：I appreciate having been given the opportunity to study abroad two years ago.我很感激两年前给我出国学习的机会。

(3)有些动词后使用动名词和动词不定式作宾语的差别

1）forget to do 忘记要去做某事（此事未做）

  forget doing忘记做过某事（此事已做过或已发生）

2）stop to do 停止、中断（某件事），目的是去做另一件事

  stop doing 停止正在或经常做的事

3）remember to do 记住去做某事（未做）

  remember doing记得做过某事(已做)

4) regret to do对要做的事遗憾

  regret doing对做过的事遗憾、后悔

5）try to do努力、企图做某事

  try doing试验、试一试某种办法

6) mean to do打算，有意要…

  mean doing意味着

7）go on to do 继而（去做另外一件事情）

  go on doing 继续（原先没有做完的事情）

8）propose to do 打算（要做某事）

  proposing doing建议（做某事）

9) like /love/hate/ prefer +to do 表示具体行为；+doing sth 表示抽象、倾向概念

（注)如果这些动词前有should一词，其后宾语只跟不定式，不能跟动名词。例如：

  I should like to see him tomorrow．

10) need, want, deserve +动名词表被动意义；+不定式被动态表示“要(修、清理等)”意思。

  Don’t you remember seeing the man before?你不记得以前见过那个人吗?

  You must remember to leave tomorrow．你可要记着是明天动身。

  I don’t regret telling her what I thought．我不后悔给她讲过我的想法。(已讲过)

  I didn’t mean to hurt your feeling．我没想要伤害你的感情。

This illness will mean(your)going to hospital．得了这种病(你)就要进医院。

4．不定式、现在分词和过去分词作定语的区别

(1）不定式作定语

  1)不定式与其所修饰的名词可能是主谓关系

  He was the last one to leave school yesterday．昨天他是最后一个离开教室的。

  The train to arrive was from London．将要到站的火车是从伦敦开来的。

  2)不定式与其所修饰的名词可能是动宾关系

  Get him something to eat．给他拿点儿东西吃。

  She has a lot of work to do in the morning．早上他有很多工作要做。

  3)不及物动词构成的不定式做定语，要加上适当的介词和被修饰的名词形成逻辑上的动宾关系，这里的介词不能省去。

  I need a pen to write with．我需要一支笔写字。

  There is nothing to worry about．没有什么值得发愁的。

  4)不定式修饰一些表示方向、原因、时间、机会、权利等抽象名词如：

  ability能力，本领 drive赶，驾驶 movement运动，活动

  ambition抱负，野心 effort努力，尝试 need需要，需求

  campaign战役，运动 failure失败，不及格 opportunity机会

  chance机会 force力，压力，要点 promise许诺，希望

  courage勇气 intention意向，意图 reason理由，原因

  decision决定 method方法，方式 light光，光线，亮光

  determination决心，决定 motive动机，目的 struggle奋斗，努力，

  tendency倾向，趋势 wish希望，愿望，祝愿

  5）被修饰的名词前有序数词、形容词最高级或next， second, last, only和not a，the等限定词时候，只能用不定式。

6）不定代词something, nothing, little, much, a lot 等习惯上用不定式做定语。

  John will do anything but work on a farm．除了农活，约翰什么都愿意干。

7）如果其动词要求用不定式做宾语，或者其形容词要器接不定式做补语，则相应的名词一般用不定式做定语。如： tend to do---tendency to do；decide to do = decision to do；be curious to do = curiosity to do

  His wish to buy a car came true．他要买辆车的愿望实现了。

  Their decision to give up the experiment surprised us．

  他们放弃这个实验的决定使我们大吃一惊。

  He is always the first to come and the last to leave．

  他总是第一个到来，最后一个离去。

(2)分词作定语

  分词作定语时有下面几个特点：

  1)现在分词表示主动意义，过去分词一般表示被动含意。

  2)现在分词表示正在进行，过去分词表示状态或做完(完成)的事。

  He rushed into the burning house．他冲进了正在燃烧着的房子。

  The child standing over there is my brother．站在那儿的男孩子是我弟弟。

  The room facing south is our classroom．朝南的房间是我们的教室。

  Have you got your watch repaired? 你拿到那个修好的表了吗?

  He is an advanced teacher．他是个先进教师。

3）下列不及物动词也以过去分词形式做定语或表语，但不具有被动意义，这点要注意：

departed, elapsed, faded, fallen, gone, frown-up, retired, returned, risen, set, vanished, much-traveled, newly-arrived, recently-come

(3)不定式和分词作定语时的时间关系

一般来说，不定式所表示的动作发生在谓语动词所表示的动作之后；现在分词所表示的动作与谓语动词所表示的动作同时发生；过去分词表示的动作发生在谓语动词所表示的动作之前。例如：

Do you want to see the doctor to be sent for from Beijing?

你要见那位将从北京请来的医生吗？

Do you want to see the doctor working on the case report in the office?

你要见那位正在办公室里写病历的医生吗？

5．不定式和分词作状语的区别

（1）现在分词与过去分词作状语的区别。

  现在分词做状语与过去分词做状语的最主要区别在于两者与所修饰的主语的主动与被动关系的区别。

1）现在分词作状语时，现在分词的动作就是句子主语的动作，它们之间的关系是主动关系。

He went out shutting the door behind him.

他出去后将门随手关上。

Not knowing what to do, he went to his parents for help.

由于不知如何办是好，他去找父母帮忙。

2）过去分词作状语时，过去分词表示的动作是句子主语承受的动作，它们之间的关系是被动关系。

Given more attention, the trees could have grown better.

如果对这些树多关心一些，它们本来会长得更好。

Faced with difficulties, we must try to overcome them.

在遇到困难的时候，我们必须设法克服。

(2)动词不定式和分词作状语的区别

1)分词作状语一般表示伴随，而不定式常常表示目的。

  They stood by the roadside talking about the plan．他们站在路边谈论着这个计划。(伴随)

  They stood by the roadside to talk about the plan．他们站在路边为的是谈论这个计划。(目的)

2)分词作状语放在句子开头，除表示原因之外有时表示时间或条件。动词不定式作状语时，除了表示目的以外，还表示结果或原因。

  Reading attentively，he forgot the time for lunch．由于在专心读书，他忘了吃午饭的时间。(原因)

  Reading carefully，he found something he had not known before．他仔细读书时，发现了一些从前不知道的东西。(时间)

  Reading carefully，you"ll learn something new．只要你仔细阅读，你会学到一些新的东西。(条件)

  His family was too poor to support him．他的家庭太穷，不能维持他的生活。(结果)

  The boy is not tall enough to reach the book shelf．这男孩个子不够高，手伸不到书架。(结果)

We are glad to hear the news．我们很高兴听到这消息。(原因)

（3）下面一些句型是不定式做状语时候应该注意的：

  a：not/never too…to, too…not to , but/only too… to, too ready/eager/apt/inclined to 表示肯定意义

  b：做结果状语的不定式只能出现在句子的末尾，常见的不定式动词有：find, hear, see, be told, form, give, make, produce 等。

  c：不定式做状语时，其逻辑主语一般为句子的主语，否则用for引导主语。

6．非谓语动词常考的其它结构

（1)疑问词+不定式结构

  疑问词who，what，which，when，where和how后加不定式可构成一种特殊的不定式短语。它在句中可以用作主语、宾语、表语和双重宾语。如：

  When to start has not been decided．何时动身尚未决定。(主语)

  I don’t know what to do．我不知道该怎么办。(宾语)

  The difficulty was how to cross the river．困难在于如何过河。(表语)

I can tell you where to get this book.我可以告诉你哪里可以买到此书。（双重宾语）

（注）A.有时疑问词前可用介词，如：

  I have no idea of how to do it.我不知道如何做此事。

  B.动词know 后面不能直接跟不定式作宾语，只能跟疑问词（如：how, what）+不定式：

While still a young boy, Tom knew to play the piano well and as he grew older, he wrote operas, the most famous of which is Carmen.

(2)介词except和but作“只有…，只能…”讲时跟不定式结构（but与不带to的不定式连用）。

  When the streets are full of melting snow, you cannot help but getting your shoes wet.

(3)不带to的不定式

1）在表示生理感觉的动词后的不定式不带to。这类词有：

feel 觉得 observe 注意到，看到 overhear听到

watch注视 listen to听 perceive察觉，感知

notice注意 see看见 look at看 hear听

  On seeing the young child fell into the lake，Eric sprang to his feet，and went on the rescue.

2)另一类是某些使役动词，如make, let，have等。如：

  Let him do it.让他做吧。

  I would have you know that I am ill．我想要你知道我病了。

  (注)：

  ①上述感觉动词与使役动词转换为被动结构时．其后的不定式一般需带to，如：

  He was seen to come．

  The boy was made to go to bed early.

  ②在动词find与help之后，不定式可带to亦可不带to，如:

  He was surprised to find the sheep (to) break fence at this season．他发现羊在此季节越出栅栏，感到惊讶。

  3)在do nothing／anything／everything but(except)结构中。例如：

  Last night I did nothing but watch TV．昨天晚上，我除了看电视别的什么也没有干。

  但是，如果谓语动词不是“do nothing，anything，everything”，那么but(except)所跟的不定式则仍须带。

  The doctor told him nothing but to stop smoking．医生除了让他戒烟，其它什么都没有说。

There was nothing for them to do but to remain silent．除了保持沉默以外，他们没有别有别的办法。

（4）不定式与动名词的逻辑主语和分词独立结构

1)不定式的逻辑主语为：for +名词(或代词宾格)+ 不定式。例如：

  I found it impossible for him to do the job alone．我发现他—个人干这活是不可能的。

  (注)在表示人物性格、特性等的形容词后面，常用of引出不定式的逻辑主语。例如：

  It was wise of him to do that．他那样做是明智的。

2)动名词的逻辑主语为；①人称代词的所有格+动名词；②名词’s+动名词。例如：

  Tom insisted on my going with them．他坚持要我和他们一起去。

7．非谓语动词中的有关句型

（1）动名词作主语的句型

  1）Doing...+ v. Reading is an art.阅读是门艺术。Seeing is believing.眼见为实。

  2) It is + no use, no good (fun, a great pleasure, a waste of time, a bore...)等名词+doing sth.

  6)have difficulty /trouble/problem + (in)+doing

  have作有解时，后接情感名词(in可省略)，再接动名词。这类词还有trouble, fun, a hard time, a good time.

  例如：We had difficulty (in) carrying out the plan．我们执行计划有困难。

  10）cannot help doing sth.忍不住（做什么）

  (2)有关分词句型

  1)在表示感觉和心里状态的动词see，hear，feel，smell，listen(to)，notice，observe，smell，watch这类表示感觉的动词之后常跟“宾语+现在分词”的复合结构，这种动词与分词之间的宾语可以是普通名词或专有名词(人各等)，也可以是代词宾格(him，us等)。例如：

  She smelt something burning and saw smoke rising．她闻到有东西在燃烧并看到有烟升起来了。

  I watched them rehearsing the play．我看他们排演戏。

  I could feel the wind blowing on my face．我能感觉到风在我脸上吹过。

  2)表示“致使”等意义的动词，如：catch，find，leave，give，have，get，set后也可跟上述(1)的结构，有时也可跟过去分词结构。例如：

  I caught them stealing my apples．我抓住他们偷我的苹果。

  If she catches me reading her diary，she"ll be furious.如果她抓住我偷看她的日记，她会愤怒的。

  We found him waiting to receive us．我们发现他正等着接待我们。

I’ll go camping tomorrow．我明天去露营。

  5)What do you say to + ing分词?(……怎么样?)

can not help but do, can not but do, cannot choose but do, can do nothing but do, have no choice/alternative to do

When I consider how talented he is as a painter, I cannot help but believe that the public will appreciate his gift.

(4)there be的非谓语形式

  there be非谓语形式可在句中作主语、宾语、状语和定语。(其中作宾语和状语在1991年和1994年测试过，定语见1996年题10。)

  The students expected there to be more reviewing classes before the final exams．(作宾语如1991年题30)

  1)作动词宾语时，通常用there to be结构，而不用there being。能这样用的及物动词为：expect，like，mean，intend，want，prefer，hate等，如：

  We don"t want there to be any comrades lagging behind，我们不希望有任何同志掉队。

  They hate there to be long queues everywhere.他们不愿意处处都要排长队。

  We have no objection to there being a meeting here．我们并不反对在这里开会。

  It isn"t enough for there to be a frost tonight，so I can leave Jim"s car out quite safely．(作状语)

  2)作状语多用there being结构，但若置于介词之后，for用there to be整个介词短语作程度状语，其它多半用there being。

  There being nobody else at hand, I had to do by myself．由于附近没有人，我只得独自干了。(原因状语)

  It’s too early for there to be anybody up．太早了，还不会有人起床。(作程度状语)

  There having been no rain for a long time，the ground was very dry．因为好长时间没下雨了，地面非常干燥。(原因状语)

  3)作主语时两种结构都可以，但如是用for引导则要用there to be。

It is not uncommon for there to be problems of communication between old and young．老人与年青人之间存在着沟通问题是很常见的。

There being a kindergarten on campus is a great convenience to female teachers．幼儿园在校园内对女教师十分方便。

  4)作定语。 There be结构作定语时，定语从句中谓语为there be，there之前的关系代词常常省略。如：

  This is the fastest train (that) there is to Nanking．这是到南京的最快一班车。

  I must make full use of the time there is left to me and do as much as I can for the people．我要充分利用我剩下的岁月尽量为人民多做些事。
