  • 宾语从句

疑问代词:
疑问代词在句中起名词的作用,用来构成疑问句。常用的疑问代词有:   
what, who, whose, whom, which, whatever, whichever, whoever, whomever   
疑问代词在句中应位于谓语动词之前,没有词性和数的变化,除who之外也没有格的变化。 
what, which, whose还可作限定词。
Whose books are these on the desk?
桌上的书是谁的?
What was the directional flow of U. S. territorial expansion?
美国的领土扩张是朝哪个方向的?
What events led to most of the east of the Mississippi River becoming part of the United States?
哪些事件使密西西比河以东的大部分土地归属于美国?
疑问代词在句中起名词词组的作用,用来构成疑问句。疑问代词有下列几个:
指 人: who, whom, whose
指 物: what
既可指人又可指物: which


疑问代词说明:
一、无论是做疑问代词还是限定词,which 和 what 所指的范围不同。what所指的范围是无限的,而which则指在一定的范围内,例如:
Which girls do you like best?
你喜欢哪几个姑娘?
What girls do you like best?
你喜欢什么样的姑娘?

二、Whom是who的宾格,在书面语中,它作动词宾语或介词宾语,在口语中作宾语时,可用who代替,但在介词后只能用whom, 例如:
Who(m) did you meet on the street?
你在街上遇到了谁?(作动词宾语)
Who(m) are you taking the book to?
你要把这书带给谁?(作介词宾语,置句首)
To whom did you speak on the campus?
你在校园里和谁讲话了?(作介词宾语,置介词 后,不能用who取代。)

三、疑问代词用于对介词宾语提问时,过去的文体中介词和疑问代词通常一起放在句首,现代英语中,疑问代词在句首,介词在句未,例如:
For what do most people live and work?大部分人生活和工作的目的是什么?(旧文体)
What are you looking for?你在找什么?(现代英语)

四、疑问代词还可引导名词性从句,例如:
I can't make out what he is driving at.
我不知道他用意何在。
Can you tell me whose is the blue shirt on the bed?
你能告诉我床上的蓝衬衣是谁的吗?
Much of what you say I agree with, but I cannot go all the way with you.
你说的我大部分同意,但并不完全赞同。


疑问代词用法:
1. 疑问代词有who, whom, whose, which和what, 都是用来构成疑问句的:
Who is calling? 谁打电话来?
Whom do you want to speak to? 你想找谁接电话?
作主语时用who,作宾语时用whom,在口语中用who作宾语时也不少:
Who did you mean? 你指的是谁?
Who are you talking about? 你们在讲谁?
直接跟在介词后时只能用whom:
With whom did you come? 你和谁一道来的?
(口语中说“Who did you come with?时更多一些。)

2. 其他三个疑问代词可用作:
1)主语:
What’s your address? 你的地址怎样写?
Whose is better? 谁的好一些?
Which of these is yours? 哪一本是你的?
2)宾语:
What do you mean? 你是什么意思?
Which do you like better? 哪一个你更喜欢一些?
Whose have you chosen? 你选了谁的?
3)表语:
What’s her name? 她叫什么名字?
Whose is it? 这是谁的?
4)定语(这样用时有些字典标作形容词):
What time does the train leave? 这列火车什么时候离开?
Which room shall we stay in? 我们住哪间房?
Whose passport is this? 这是谁的护照?
副词的比较级和最高级:
当两种物体之间相互比较时,我们要用形容词或副词的比较级;
当相互比较的物体是三个或三个以上时,我们就要用形容词或副词的最高级。
副词比较级和最高级的变化规则和形容词相似。
副词比较级的变化规则:

一、规则变化

1.一般在词尾直接加erest。hard—harder—hardest ;long-longer-longest

2.以不发音的字母e结尾的单词在词尾直接加rst。nice-nicer-nicest

3.以辅音字母+y结尾的词,把y变为i,再加erest。early—earlier—earliest 
4.重读闭音节,末尾只有一个辅音字母,双写这个辅音字母,再加erest,例如,big-bigger-biggest

5.部分双音节词和多音节词分别在原级前加more构成比较级和most构成最高级, carefully—more carefully—most carefully

二、不规则副词的比较级和最高级

 原级 比较级  最高级 
 well  better best 
 badly worse  worst 
 much more  most 
 little  less lest 
 far  farther(指距离) farthest(指距离) 
 further(指距离和抽象概念) furthest(指距离和抽象概念) 

以ly结尾的副词,比较级有两种情况:
一种单词里本身就以结尾early;
另一种是由形容词+变为的副词 slowly,happily ,easily,他们改为比较级时 是不一样的。
例如:第一种情况,直接进行词尾变化early-earlier;
而第二种情况, 就要在副词原级前面+more,构成比较级。
因此,easily 的比较级应该是:more easily 。
副词等级的用法:
一、原级的用法

1.只能修饰原级的词,very,quite,so,too。例如:
He is too tired to walk on.他太累了以至于不能再继续走了。
My brother runs so fast that I can‘t follow him.我弟弟跑得那么快以至于我跟不上他。
2.原级常用的句型结构
(1)“甲+实意动词+(倍数)+as+副词原级+as+乙”表示“甲和乙程度相同”或“甲是乙的几倍”。例如:
Tom runs as fast as Mike.汤姆和迈克跑得一样快。
Tom runs twice as fast as Mike.汤姆跑得速度是迈克的二倍。
(2)“甲+助动词+not+动词原形+as/so+副词原级+as+乙”甲不如乙…例如:
He doesn’t walk as slowly as you.他走路不像你那样慢。

二、比较级的用法
1.可以修饰比较级的词,much,a lot,far,…的多; a little,a bit,…一点儿; even甚至;;still仍然。例如:
Lesson One is much easier than Lesson Two.第一课比第二课容易得多。
Tom looks even younger than before.汤姆甚至比以前更年轻。
This train runs much faster than that one.这辆火车比那辆跑地快。
She drives still more carefully than her husband.她开车仍然比她丈夫还认真。

2.比较级常用的句型结构
(1)“甲+实意动词+(倍数)+副词比较级+than+乙”表示“甲比乙…”或“甲比乙…几倍”。例如:
I got up earlier than my mother this morning.我今天早晨起床比我妈妈还早。
He runs three times faster than his brother.他跑的速度比他弟弟快三倍。
(2)“甲+实意动词+副词比较级+than+anyother+单数名词(+介词短语)”表示“甲比同一范围的任何一个人/物都……”,含义是“甲最……”。例如:
Mike gets to school earlier than any other student in his class.
= Mike gets to school earlier than any of the other students in his class.迈克比他们班上任何一个其他的同学到校都早。
= Mike gets to school earlier than the other students in his class.迈克比他们班上其他的同学到校都早。
= Mike gets to school earliest in his class.迈克在他们班到校最早。
注意:Mike gets to school earlier than any student in Tom’s class.迈克比汤姆班上任何一个学生到校都早。(迈克和汤姆不是同一个班)
(4)“比较级+and+比较级”表示“越来越……”。例如:
He is getting taller and taller.他变得越来越高了。
The flowers are more and more beautiful.花儿越来越漂亮。
He does his homework more and more carefully.他做作业越来越认真了。
(5)“the+比较级,the+比较级”表示“越……,越……”。例如:
The more careful you are,the fewer mistakes you’ll make.你越认真,犯的错误越少。
(6)“特殊疑问词+实意动词+副词比较级,甲or乙?”例如:
Who draws better,Jenny or Danny?谁画得比较好,詹妮还是丹尼?

三、最高级的用法
最高级常用句型结构
(1)“主语+实意动词+(the)+副词最高级+单数名词+in/of短语”表示“……是……中最……的”。例如:
I jump (the) farthest in my class.我是我们班跳得最远的。
(2) “特殊疑问词+be+the+副词最高级+甲,乙,or丙?”用于三者以上的比较。例如:
Which season do you like (the) best,spring,summer or autumn?你最喜欢哪一个季节,春天,夏天还是秋天?
(3)“特殊疑问词+be+the+最高级+甲,乙,or丙?”用于三者以上的比较。例如:
Which country is the largest,China,Brazil or Canada?哪一个国家最大,中国,巴西还是加拿大?

从属连词:
这种连词是用以引导名词性从句定语从句和状语从句的,由从属连词所引导的句子叫从句,而含有从句的句子叫作复合句。

从属连词可分为三大类:
1、that (无词义,不做成分)
if,whether (表达是否的意义,但不做句子成分)
2、连接代词:who,whom,whose,what,which,whatever, whoever, whichever(有词义,在句子中可作主语、表语、宾语)
3、连接副词:when,where,why,how,how many,how long,how far,however,whenever,wherever (有词义,作从句的状语)

用法:
从结构上说,英语连接词分两大类:并列连词和从属连词。

并列连词连接两个或两个以上地位平等的字、词组或分句。例如:
(1) Air and water are indispensable to me.   
(2) She likes going out with friends or playing outdoor games.   
(3) Most workers have a good income, so they look very happy.   

从属连词连接两个或两个以上的分句,形成复杂句中的从属分句。例如:   
(4) He said that he did not want to go .   
(5) Many things have happened since I last saw him.   
(6) You may come if you want to.   

从属连词用来连接各种从句。
until(till)直到,在用until表达时间状语的句子中,主句中的动词是要十分小心去选择的。
如动词是持续行动词,它要用肯定句,如:
I studied hard until 12 o'clock last night.
如果动词是瞬间截止性动词,则要用否定句,如:
He didn't go to bed until his mother came back.
由since,for,by,before, 来引导的时间状语从句。
since 引导的时间状语是动作的开始时间,如:
I have studied English since 1990.
而by引导的时间状语通常是动作的结束时间,如:
I had learned 25 English songs by the end of last term.


从属连词语法分类:
种类 语法作用 连词举例 
从属连词 引导原因状语从句 Because, since
引导条件状语从句 If, unless, as long as
引导目的状语从句 So that
引导结果状语从句 So…that
引导方式状语从句 As, just as, as if
引导让步状语从句 Though, although, even
though, no matter what,
however, no matter how,
whoever, no matter who,
wherever, no matter where
引导比较状语从句 As…as, not so…as, than,
less…than, the more…the
more
引导名词性从句 Who, whom, whose, which,
that, when, where, why

宾语从句:
在句子中起宾语作用的从句叫做宾语从句。
宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。
宾语从句连接代词主要有:
who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever 等。

宾语从句的特点:
1.宾语从句可以作及物动词、介词及形容词的宾语。
2.宾语从句的语序一律用陈述句语序。
3.连接词that引导宾语从句在句中无词义,不充当句子成份,多数情况下可以省略。
4.whether 和 if 都可引导宾语从句,但 whether后可紧跟or not;whether从句可作介词的宾语。
5.如果从句太长,可以用形式宾语it.

宾语从句的时态:
1.主句是一般现在时,从句根据实际情况使用任何时态。
例句:The headmaster hopes everything goes well.
2.主句是过去时态,从句须用过去时态的某种形式。
例句:She was sorry that she hadn’t finished her work on time.
3.当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态。
例句:The teacher told his class that light travels faster than sound.
4. 如果从句的动作发生在主句之前,则从句要用过去完成时态。 

宾语从句的语序:
A. 宾语从句必须用陈述语序。   
False: He is wondering when can he finish this difficult job.   
Right: He is wondering when he can finish this difficult job.
B. 有时候可以用it 作形式宾语,而把真正的宾语从句放在后面。    
Bad: I thought that he could finish this job in just two hours impossible.   
Good: I thought it impossible that he could finish this job in just two hours.  
C. 带有宾语从句的复合句的否定形式一般是否定主句。
Bad: I think he doesn’t like the English teacher.   
Good: I don’t think he likes the English teacher. 
D.  主句一般过去时态,从句也要用过去时态。
False: He wanted to know why he is crying in the corner.   
Right: He wanted to know why he was crying in the corner

宾语从句的否定转移:
主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等。
并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致。
I don’t think he will come to my party.而不能说成I think he won’t come to my party.
我认为他不会来我的舞会.
I don’t believe that man is killed by Jim,is he?
我认为那个人不是Jim所杀的,是不是?
如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式。
We find that he never listens to the teacher carefully,does he?
我们发现他从来不仔细听老师讲课,是不是?


宾语从句中引导词的用法比较
在复合句中作主句的宾语,引导词有:
连词:that (that 常可省略),whether, if
代词:who, whose, what ,which
副词:when ,where, how, why 等。

(一)that引导的宾语从句(在非正式场合that可以省略)
1.可跟that从句做宾语的动词有:
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句:The boy believes that he will travel through space to other planets.
注意事项:当主句谓语动词是 think, believe, suppose, expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示。
例句:I don’t think it is right for him to treat you like that.

2.在以下情况中that不能省略
a.当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省。
例句:He said (that) you were too young to understand the matter and that he was asked not to tell you.
b.当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省。
例句:Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
c.当that从句是双宾语中的直接宾语时,that不可省。
例句:I can’t tell him that his mother died.
d.注:许多带复合宾语的句子,that引导的宾语从句经常移到句子后部,而用it作形式宾语。
例句:I find it necessary that we should do the homework on time.

(二)由whether,if 引导的宾语从句
1.由whether(if)引导的宾语从句,实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。
一般说来,在宾语从句中whether与if可以互换使用,但在特殊情况下if与whether是不能互换的。
例句:I wonder whether(if) they will come to our party.

2.只能用whether,不能用if引导的宾语从句
a.在带to的不定式前
例句:We decided whether to walk there.
b.在介词的后面
例句:I’m thinking of whether we should go to see the film.
c.在动词后面的宾语从句时
例句:We discussed whether we had a sports meeting next week
d.直接与or not连用时
例句:I can’t say whether or not thet can come on time.

3.只能用if不能用whether引导的宾语从句
a.if引导条件状语从句,意为“如果”
例句:The students will go on a picnic if it is sunny.
b.if引导否定概念的宾语从句时
例句:He asked if I didn’t come to school yesterday.
c.引导状语从句even if(即使)和as if(好象)时
例句:He talks as if he has known all about it.

if,whether在宾语从句中的区别
a.if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if
b.少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether. 
c. whether后可以加or not,但是if不可以.
d.在不定式前只能用whether.
(如:I can’t decide whether to stay. 我不能决定是否留下。)
e.避免歧异时,我们常用whether而不用if.

(三)连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句要用陈述句语序。
用于这种结构的动词常常是:see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
1.英语中的连接代词有:who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。
例句:Can you tell me whom you are waiting for?
2.英语中的连接副词有:when,where,why,how,在句中担任状语的成分。
例句:None of us knows where these new parts can be bought.


简化宾语从句常用六法:
方法一:
当主句谓语动词是hope, decide, wish, choose, agree, promise等,
且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。
例如:
Li Ming hopes he will be back very soon.
→Li Ming hopes to be back very soon.
We decided that we would help him.
→We decided to help him.

方法二:当主句谓语动词是know, learn, remember, forget, tell等动词,
且主句主语与从句主语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
She has forgotten how she can open the window.
→She has forgotten how to open the window.
注:当主句谓语动词是tell, ask, show, teach等动词,
且后带双宾语,从句主语和间接宾语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
Could you tell me how I can get to the station?
→Could you tell me how to get to the station?

方法三:当主句的谓语动词是order(命令),require(需要)等时,
如果主句和从句的主语不一致,宾语从句可简化为“名词(代词)+不定式”结构。例如:
The headmaster ordered that we should start at once.
→ The headmaster ordered us to start at once.

方法四:某些动词后的宾语从句,可以用介词加动名词(短语)等其他形式简化。例如:
He insisted that he should go with us.
→He insisted on going with us.
The poor boy doesn’t know when and where he was born.
→The poor boy doesn’t know the time and the place of his birth.

方法五:某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。例如:
Liu Ping found that there was a wallet lying on the ground.
→ Liu Ping found a wallet lying on the ground.

方法六:动词seem后的宾语从句,也可以用不定式(短语)来简化,但句型需要进行适当的变化。例如:
It seemed that the boys were going to win.
→The boys seemed to win.
除上述方法外,还有一些特殊句式的转化。例如:
I found that it was difficult to learn English well.
→I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow.
→Soon we found the ground covered with thick snow.
They found that the box was very heavy.
→They found the box very heavy
