I found him lying on the ground.

I found it important to learn.

I found that to learn English is important.

典型例题

答案：A. 由consider to do sth. 排除B、D。. 此句只说明发明这一个事实，不定式后用原形即可。而C为现在完成时，发明为点动词一般不用完成时，且此处也不强调对现在的影响，因此不选C。

3) 当不定式作主语的句子中又有一个不定式作表语时，不能用It is… to…的句型

(对)To see is to believe.　百闻不如一见。(错)It is to believe to see.

It's for sb.和 It's of sb.

1) for sb. 常用于表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult,　 interesting, impossible等：

2) of sb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。

It's very nice of you to help me. 你来帮助我，你真是太好了。

for 与of 的辨别方法

用介词后面的代词作主语，用介词前边的形容词作表语，造个句子。如果道理上通顺用of，不通则用for。如：You are nice.　(通顺，所以应用of)。He is hard.　(人是困难的，不通，因此应用for。)

4. 不定式作表语

不定式可放在be动词后面，形成表语。例如：

My work is to clean the room every day.

典型例题

The chair looks rather hard, but in fact it is very comfortable to ___.

A. sit　 B. sit on　 C. be seat　 D. be sat on

答案：B.　如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。

用作介词的to

to 有两种用法：一为不定式+动词原形; 一为介词+名词/动名词, to 在下面的用法中是第二种，即to+ 名词/动名词：admit to承认，confess to承认，be accustomed to 习惯于，be used to 习惯于，stick to 坚持，turn to开始，着手于，devote oneself to 献身于，be devoted to 致力于， look forward to 盼望，pay attention to

9) 通常在discover, imagine, suppose, think, understand等词后，可以省去to be：He is supposed (to be) nice.　他应该是个好人。举例：He wants to move to France and marry the girl. He wants to do nothing but go out. 比较：He wants to do nothing but go out. He wants to believe anything but to take the medicine.

典型例题

---- Why not ___ by boat for a change?

A. to try going　 B.　trying to go　 C.　to try and go　 D.　try going

4) The boy wanted to ride his bicycle in the street，but his mother told him ____.

A. not to　　B. not to do　　C. not do it D. do not to

5) The patient was warned ___ oily food after the operation.

A. to eat no　 B. eating not　 C. not to eat　D. not eating

答案：C。warn一词要求后用不定式，此处为不定式的被动，否定形式为be warned not to do。

第六章 倒装结构

一　全部倒装

全部倒装是指将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和一般过去时。常见的结构有：

1. here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。例如：

1) There goes the bell.　铃声渐渐消失了。

2) Then came the chairman.　然后主席就来了

3) Here is your letter.　这是你的信。

2. 表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。例如：

1) Out rushed a missile from under the bomber.　轰炸机下面发出了一颗导弹。

2) Ahead sat an old woman.

注意：上述全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。例如：

1) Here he comes. 他来了。

2) Away they went.　他们走了。

二　部分倒装

部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。

1.　句首为否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。例如：

1) Never have I seen such a performance. 我从来没看过这样的表演。

2) Nowhere will you find the answer to this question.　你在哪儿都不会找到这个问题的答案。

3) Not until the child fell asleep did the mother leave the room.　妈妈直到孩子睡着才离开房间。

注意：当Not until引出主从复合句，主句倒装，从句不倒装。

注意： 如否定词不在句首不倒装。例如：

1) I have never seen such a performance.我从来没看过这样的表演。

2) The mother didn't leave the room until the child fell asleep.妈妈直到孩子睡着才离开房间。

2.　带有否定意义的词放在句首，语序需要部分倒装。常见的词语有： not , never , seldom , scarcely , barely , little , at no time , not only , not once , under on condition , hardly … when , no sooner …than …等。例如：

1) Not only did he refuse the gift, he also severely criticized the sender.　他不仅拒收了礼品，还狠狠批评了送礼的人。

2) Hardly had she gone out when a student came to visit her. 她刚要出门时有个学生来找她。

3) No sooner had she gone out than a student came to visit her.　她刚要走时一个学生来看她。

注意：只有当Not only… but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语，不可用倒装结构。例如：

Not only you but also I am fond of music.　我和你都喜欢音乐。

3.　表示"也"、"也不" 的so, neither, nor放在句首时，句子作部分倒装。例如：

1) Tom can speak French. So can Jack.　Tom能说法语，我也能。

2) If you won't go, neither will I.　如果你不去，我也不去。

注意： 当so引出的句子用以对上文内容加以证实或肯定时，不可用倒装结构。意为"的确如此"。例如：

1) Tom asked me to go to play football and so I did. Tom让我去踢足球，我去了。

2) ---It's raining hard.　　　---So it is.　---雨下得很大。　---的确很大。

4.　only放在句首，强调状语(副词，介词短语或状语从句等)，全句语序要部分倒装。例如：

Only in this way, can you learn English well.你只有用这种方法才能学好英语。

Only after being asked three times did he come to the meeting.　他被请了三次才来开会。

注意：如果句子为主从复合句，则主句倒装，从句不倒装

Only when he is seriously ill, does he ever stay in bed. 他只有病得非常严重时才会卧床休息。

三　as, though 引导的倒装句

as / though引导的让步从句必须将表语或状语提前 (形容词, 副词, 分词, 实义动词提前)。此时应注意：1) 句首名词不能带任何冠词;2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语,随实义动词一起放在主语之前。例如：

Try hard as he will, he never seems able to do the work satisfactorily.　尽管他愿意努力工作，但是他好像从来都不能令他的工作満意。

注意:　让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用。

四　其他部分倒装

1. so… that 句型中的so 位于句首时，需倒装。例如：

So frightened was he that he did not dare to move an inch.　他害怕得动都不敢动。

2.　在某些表示祝愿的句型中，例如：

May you all be happy.　望大家开心愉快。

3.　在虚拟语气条件句中从句谓语动词有were, had, should等词，可将if 省略，把 were, had, should 移到主语之前，采取部分倒装。例如：

Were I you, I would try it again.　如果我是你，我就再试一次。

第七章 定语从句

定语从句(Attributive Clauses)在句中做定语，修饰一个名词或代词，有时也可以修饰部分或整个句子。

被修饰的名词，词组或代词即先行词。定语从句通常出现在先行词之后，由关系词(关系代词或关系副词)引出。

关系代词有：who, whom, whose, that, which, as。

关系副词有：when, where, why, how。

关系代词和关系副词放在先行词和定语从句之间，起连接作用，同时又可做定语从句的一个成分。当关系代词做宾语时可以省略。

定语从句中的谓语动词必须在人称上和数量上和先行词保持一致。

定语从句分为限制性定语从句和非限制性定语从句。

1 、关系代词引导的定语从句

1) who, whom, that 这些词代替的先行词是人的名词或代词，在从句中所起作用如下：

Is he the man who/that wants to see you?(who/that在从句中作主语)

He is the man whom/ that I saw yesterday.(whom/that在从句中作宾语)

2) whose 用来指人或物，(只用作定语，若指物，它还可以同of which互换)，例如：

Please pass me the book whose (of which) cover is green.

3) which, that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：

A prosperity which / that had never been seen before appears in the countryside.(which / that在句中作宾语)

The package (which / that) you are carrying is about to come unwrapped. (which / that在句中作宾语)

关系代词that和which 都可以指物，that 和Who 都可以指人，其用法区别：

不用that的情况：

a) 在引导非限定性定语从句时

(错)The tree, that is four hundred years old, is very famous here.

b) 介词后不能用

We depend on the land from which we get our food.

c) 多用who 的情况

①关系代词在从句中做主语

A friend who helps you in time of need is a real friend.

②先行词为those, people 时

Those who were either fools or unfit for their offices could not see the cloth.

③先行词为all, anyone, ones, one 指人时

One who doesn't work hard will never succeed in his work.

④在There be句型中

There is a stranger who wants to see you.

⑤在被分隔的定语从句中

A new teacher will come tomorrow who will teach you German.

⑥在有两个定语从句的句子中，其一用who，其二用that,但若先行词后接两个以上的并列定语从句时，后一个必须重复前一个关系代词。

The student who was praised at the meeting is the monitor that is very modest and studies very hard.

There is a teacher who is always ready to help others and who enjoys what he does.

2) 只能用that作为定语从句的关系代词的情况

a)在不定代词，如：anything, nothing, everything, all, much, few, any, little等作先行词时，只用that，不用which。

All that is needed is a supply of oil.

Finally, the thief handed everything that he had stolen to the police.

b)先行词有the only, the very, the just修饰时，只用that。

He is the very man that helped the girl out of the water.

c)先行词为序数词(the last)、数词、形容词最高级时，只用that。

The first English book that I read was "The Prince and the Pauper" by Mark Twin.

d)先行词既有人，又有物时。

He talked about the teachers and schools that he visited.

e)当主句是以who 或which 开始的特殊疑问句时，用that 以避免重复。

Who is the person that is standing at the gate.

f)关系代词在从句中做表语

He is not the man that he used to be.

2 、关系副词引导的定语从句

关系副词可代替的先行词是时间、地点、方式或理由的名词，在从句中作状语。

关系副词when, where, why, how的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如：

There are occasions when (on which) one must yield.

Beijing is the place where (in which) I was born.

Is this the reason why (for which) he refused our offer?

I'm surprised the way how (by which) he works out the problem.

注意：

①在非限制性定语从句中，"介词+ which"结构不能代替关系副词。

如：They set up a state for their own , where they would be free to keep Negroes as slaves.

②含有介词短语的动词一般不能拆开，介词仍放在动词后面。

Is this the book which (that) she was looking for?

3、名词/数词/代词 /形容词最高级 + 介词 + 关系代词引导定语从句

She has written a book , the name of which I have forgotten.

There are fifty-five students in our class , all of whom are working hard.

There are five continents in the world , the largest of which is Asia.

4、as, which 引导非限定性定语从句的差别

由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。

As we know, smoking is harmful to one's health.

The sun heats the earth, which is very important to us.

as可引导非限制性从句，常带有“正如”的意思。

As is know, smoking is harmful to one's health.

用法区别：

(1) as 引导的定语从句可置于句首，而which不可。

As we all know, he never smokes.

(2) as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词;若为行为动词，则从句中的关系代词只能用which。

(3)非限定性定语从句中出现expect, think, suppose 等表示猜测、想象、预料等时。

She succeeded in her doing the research work , as we expected.

(4)As 的用法 the same… as; such…as 中的as 是一种固定结构, 和……一样……。

I should like to use the same tool as is used here.

We should have such a dictionary as he is using.

第八章 被动语态

一、语态概述

英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。

主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。

被动语态表示主语是动作的承受者，即行为动作的对象。巧记为：被动、被动、主被动。例如：

English is spoken by many people.主语English是动词speak的承受者。

主动态和被动态指的是动词形式，是词法概念;而主动句和被动句则指的是句子结构，从而是句法概念。所谓主动句就是由主动态动词(词组)作谓语动词的句子，而被动句则是由被动态动词(词组)作谓语动词的句子。例如：

He opened the door.他开了门。(主动句)

The door was opened.门被开了。(被动句)

二、被动语态的构成

被动语态由“助动词be+及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以teach为例说明被动语态在各种时态中的构成。

一般现在时：am/is/are+taught

一般过去时：was/were+taught

一般将来时：will/shall be+taught

现在进行时：am/is/are being+taught

过去进行时：have/has been+taught

现在完成时：have/has been+taught

记忆歌诀：被动语态be字变，过去分词跟后面。

注意：区分被动语态与“be+过去分词”结构

be+过去分词”并不一定都是被动语态，有时是系表结构。当“be+过去分词”表示动作时为被动语态，be是助动词，be后面的过去分词是主要动词，动作的对象是主语;当“be +过去分词”表示主语所处的状态时为系表结构，be是连系动词。be后面的过去分词是表语，相当于形容词。其区分办法如下：

1 如果强调动作或句中有介词by引导出动作的执行者，该句一般为被动语态，否则为系表结构。例如:The glass is broken.玻璃杯碎了。(系表结构) The glass was broken by the boy.玻璃杯被那男孩打碎了。(被动语态)

2 如果句中有地点、频率或时间状语时，一般为被动语态。如：The magazine is published in Shanghai.这家杂志出版于上海。(被动语态)The door is locked.门锁着。(系表结构)The door has already/just been locked.门已经/刚刚被锁上。(被动语态)The shop is opened.这家商店开门了。(系表结构) The shop is opened at 8 a.m. everyday.这家商店每天上午八点开门。(被动语态)

3 被动语态除用于一般时态和完成时态外，还可以用于其他各种时态，而系表结构中的系动词be只有一般时态和完成时态。

三、被动语态的用法

1 不知道或没有必要说明动作的执行者是谁。例如：

1) Some new computers were stolen last night.

一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)

2) This book was published in 1981.这本书出版于1981年。

2 强调动作的承受者，而不强调动作的执行者。例如：

1) This book was written by him.这本书是他写的。

2) Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保证。

记忆歌诀：谁做的动作不知道，说出谁做的没有必要;动作承受者需强调，被动语态运用到。
