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?
疑问副词:
用来引导特殊疑问句,表示时间,地点,方式,原因等。
常见的有:when,where,how,why等。

疑问副词的用法:
1.疑问副词是问何时、何地、如何、因何的副词,主要有when, where, how, why。

2.疑问副词用在句首。
How long have you been staying in America?
你在美国待多久了?

3.疑问副词在句中引导名词子句。
I want to know where she has gone.
我想知道她去哪里了。

4.疑问副词后接不定词构成的名词片语,在句中可以作主词、受词或主词补语。
How to solve the problem gives him a bad headache.
如何解决这个问题使他伤透脑筋。
(How to solve the problem作主词。)
I don't know how to answer the question.
我不知道如何回答这个问题。
(how to answer the question作受词。)
The patient is in urgent need the medicine, but the problem is where to get it.
这个病人急需这种药,但问题是哪里能找到。
(where to get it作主词补语。)

5.疑问副词引导的名词子句可作主词、受词或主词补语。
When we are to start the competition hasn't fixed yet.
我们什么时候开始比赛还没有定下来。
(When we are to start the competition作主词。)
She asked her husband where he had been.
她问她丈夫去哪里了。
(where he had been 作受词。)
The question is when we can finish our work.
问题是我们何时能完成我们的工作。
(when we can finish our work作主词补语。)


疑问代词与疑问副词的区别:
1. 疑问代词做对陈述句的主语,宾语或定语提问,即做句子的主语,宾语或定语,如what, who/ whom, whose.
eg. Who is talking ? What can you see?
Whose shirt is this?
2.疑问副词对时间,地点,方式等状语提问,如when, where, how 等.
eg. When is your birthday? Where are you going?
How do you know?
常见的疑问代词:what  who  which  whom(只做宾语)
疑问副词:how  where  when
还有whether是疑问连接词。
祈使句:
表示请求或命令的句子是祈使句。祈使句一般用降调,为使祈使句听起来比较婉转,可用低声调,祈使句句末用句号或感叹号。
每种类型又有肯定形式和 祈使句的组成
①动词原形+其他
②Please+动词原形+其他
③否定形式:don‘t+动词原形,用don’t否定时,只能用其缩略形式。
例如:
Welcome to Beijing Park. 
Walk about three blocks. 
Don’t mention it.

 

祈使句含义:

1. 表请求 
Pass me the sugar, please.
请把糖递给我。

2. 表命令 
Put up your hands.
举手。 
Fill in this form.
把这个表填好。

3. 表建议 
Let
s have dinner together. 我们共进晚餐吧。

4. 表邀请 
Come in and have a seat.
进来请坐。 
Help yourself to some fruits.
请吃水果。

5. 表警告 
Hurry up or you will be late.
抓紧点,不然你要迟到了。 
Do that again and you
ll be in trouble.要是再干那事,你会有麻烦的。

6. 表禁止 
Don
t touch the exhibits.不要触摸展品。 
Don
t play on the road.不要在马路上玩耍。

7. 表叮嘱             
Be sure to get there before nine.
务必在九点前赶到那里。 
Take care not to catch cold.
小心别着凉了。

8. 表号召 
Workers of all countries, unite!
全世界工人阶级联合起来!

9. 表祝愿 
Have a good trip.
祝你旅途愉快。


祈使句有三种类型:
一、含第二人称主语的祈使句
1. 当祈使的对象是第二人称you时称为含第二人称主语的祈使句。
这时,主语you通常不出现在句中,谓语动词用原形。
有时在句首或句末加please,还可加上称呼语,用逗号与句子主体隔开。如:
Please be quiet, boys! 孩子们,请安静!
Come this way, please. 请走这边。
如要加强语气,可在动词前加do。如:
Do keep away from the fire! 切记远离火种!
2. 否定式在谓语动词前加Don’t或Do not,强调否定式则在动词前加Never。如:
Don’t alway make the same mistake. 不要老犯同一个错误。
Never be late again. 千万别再迟到了。
3. 有时,为了强调指明向谁提出要求或发出命令,或表达说话人的急躁、厌烦、不满、恼怒的情绪,就用主语you表示,且放在动词前。如:
You come here! 你到这里来!
You mind your head! 小心别碰到头了!
若为否定式,则把Don’t放在主语you之前。如:
Don’t you come here! 你别来这里!

二、含第一、第三人称主语的祈使句
1. 含第一或第三人称主语的祈使句通常以Let开头,
第一人称由“Let + me / us +动词原形”构成,
第三人称由“Let + 第三人称代词(用宾格)或名词+动词原形”构成。
这类祈使句往往用于提出建议。如:
Let me have a try if you don’t want to. 如果你不想,就让我试一试吧。
Let’s spend this weekend in the country. 咱们到乡下去度这个周末吧。
Let him be here by ten o’clock. 叫他10点到这里吧。
有时也可以先称呼对方的名字,,后跟一句无人称主语的祈使句。如:
Jane, sit down please. 简,请坐下。
Mum, remember to bring me an umbrella. 妈妈,记得给我带把伞。
2. 这类祈使句的否定式是在动词原形前加not,也可以在let前加Don’t。如:
Let’s not wast our time about it. 我们不要为了这件事而浪费时间。
Don’t let us wait here. 别让我们在这儿等。
Don’t let him go out. 别让他出去。

三、无动词祈使句
在请求、命令和口号中,常用无动词祈使句,它实际上是省略了动词,从而使语句更简洁或有力。如:
Just a minute, please! 请稍等!
This way, please! 请这边走!
Attention! 立正!
Up the stairs! 上楼!
To the playground, everyone of you! 到操场上去,你们每个人都得去!
在一些指示牌上,常用“No +动名词/名词”构成简略式的否定祈使句。如:
No smoking! 禁止抽烟!
No parking! 禁止停车!
No photos! 禁止拍照!
还有一些是祝词类的无动词祈使句,如:
May you succeed!祝你成功!
Long live our friendship!我们的友谊万岁!



祈使句特点口令:
祈使句无主语, 主语you常省去;
动词原形谓语当, 句首加don't否定变;
朗读应当用降调, 句末常标感叹号。

祈使句的语调特点 :
1、语音强度一般比陈述句重,书面上用叹号表示。
2、句末用降调,较长句子的后半部分几个音节速度加快。

对特定的人使用的祈使句:
祈使句如Wait here! (在这儿等着!) 可以是对一个人说,也可以是对几个人说,其主语暗含you。
但我们却可以用下列方式引起我们说话的对象的注意:
■You+祈使语气动词
You wait here for a moment. 你在这儿等一会儿。
语调和重音很重要。在上面这一句里,如果不重读you,那么句子的意思是this is where you wait (这就是你应等着的地方);
如果重读you,那么句子的意思就是this is what I want you to do (这是我要你做的事)。
此外,重读you时还可以表示愤怒、敌意或不客气。如:
You mind your own business! 不关你什么事
You try teaching 40 noisy children five days a week! 你来试试每周5天教40个吵闹的孩子!
在否定句中Don’t要重读 (不重读you)。如:
Don’t you speak to me like that! 你别这样跟我讲话!

■“you+人名”或“人名+you”
You wait here, Jim, and Mary, you wait there. 你等在这儿,吉姆;玛丽,你等在那儿。

■“祈使语气+人名”或“人名+祈使语气”:
Drink up your milk, Sally! 把你的牛奶喝光,萨利!
Sally, drink up your milk! 萨利,把你的牛奶喝光!

■祈使语气+反身代词
Enjoy yourself. 你好好享受吧。
Behave yourself. 你放规矩点。

■对一群人讲话时,祈使语气可与everybody, someone之类的词连用:
Everyone keep quiet! 大家安静!
Keep still everybody! 每个人都保持不动!
Nobody say a word! 都不许说话!
Somebody answer the phone please. 请来个人接电话。

■在表示否定的命令语气后面可用带any的复合词
Don’t say a word anybody! 谁都不要说话!
Don’t anybody say a word! 任何人都不许说话!


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



选择疑问句:
是指提出两个或两个以上可能的答案供对方选择的句式。
一种是以一般疑问句的结构形式为基础,只是在语调上有所区别。
这一类选择疑问句通常都是在前一个供选择的答案用低升调,后一个用降调;
如果有两个以上供选择的答案,则在最后一个用降调,其余都用低升调。
另一种是以特殊疑问句为基础。Or连接的两个并列成分可以是状语、宾语、表语、谓语或数两个句子等。
例如:
Do you want to live in a small town or a big city?
Which ocean is deeper, the Atlantic or Pacific?

选择疑问句的结构:
1、“一般疑问句+or+另一个备选对象”。例如:
Shall we go there by bus, bike or train?
我们乘公共汽车、自行车还是火车去?(备选对象为三者)
Would you like some tea or coffee?
你要茶水还是咖啡? (备选对象为二者)
Did you stay at home or at school yesterday? 
你昨天呆在家还是在学校?(备选对象为二者)

2、“特殊疑问句+or+另一个备选对象”。例如:
Which would you like best, English, Chinese or Math?
你最喜欢哪门学科,英语、语文还是数学? (备选对象为三者)
When will you go to Canada, Sunday or Monday?
你何时去加拿大,星期天还是星期一?(备选对象为二者)
选择疑问句是在一般疑问句或特殊疑问句后面用并列连词or加上一个备选对象构成的,要注意和一般疑问句或特殊疑问句结构的区别。


选择疑问句的回答:
回答选择疑问句时,一般在所提供的备选对象范围内选择,有时也要视具体情况作灵活处理,但不能用Yes / No来回答;
一般用一个完整的陈述句或其简略形式,主语和谓语均省略。
常用的不定代词有all(三者或三者以上都), both(二者都), either(二者中任意之一), neither (二者都不), none(三者或三者以上都不)。
在运用时要由上下文的语境来决定使用哪一个不定代词。
1、从备选对象中选择其中某一项回答。
─ Are you going to borrow a dictionary or a magazine?
─ ____.
A.  Yes, a dictionary       
B. No, a magazine
C.  A magazine           
D. Yes, both
分析:选项A, B, D不能回答选择疑问句。选项C是从备选对象中选择了其中的一项来回答的,符合语境。故选择C选项。

2、选对象是二者,可任选其一就用表示肯定的either;两个对象都选就用表示肯定的both;
两个对象都不选就用表示否定的neither。
─Would you like chicken noodles or beef noodles?
─____. I’d like tomato noodles.
A. Either   
B. Neither   
C. Both   
D. None
分析:备选对象是二者,先排除D。由“我要西红柿面条”可知,要否定上面提供的备选对象。而A和C选项不符合上下文的逻辑,故选B。
─Which do you like better, Math or Physics?
─_____. I’m interested in them and quite good at them.
A. Both    
B. None    
C. Either   
D. All
分析:备选对象是二者,先排除B和D。由“我对它们感兴趣,而且学得相当好”说明“我喜欢数学和物理”,C不符合逻辑,故选择A选项。
─When shall we go to the museum, this afternoon or tomorrow morning?
─____ is OK. I’m free these days.
A. Both    
B. All     
C. Either    
D. Neither
分析:备选对象是二者,先排除B。下句中动词is不能和both搭配,A也要排除。由“_____ 都可以。这几天我都有空。”
可知,空格处填肯定词either,意为“今天下午和明天早上任意一个时间都可以。”选项D 表否定不符合上下文的逻辑,故选C。

3、如果备选对象是三者,可任选其一时,就用one of them(他〈它、她〉们中任意之一);三个对象都选就用all;三个对象都不选就用none。
─Which do you like best, coffee, water or juice?
─_____. I only like tea.
A. Both   
B. Either   
C. Neither    
D. None
分析:备选对象是三者,排除A, B, C。选择D选项,意为“咖啡、水和果汁都不喜欢。我只喜欢茶水。”
