一般疑问句：
是疑问句的一种。通常用yes，no来回答的疑问句叫做一般疑问句。口语中若无特殊含义，句末用升调。
其结构是：系动词be/助动词/情态动词＋主语＋其他成分？　
通常回答为： 　　
肯定：Yes+主语+提问的助动词 　　
否定：No+主语+提问的助动词+not 
例如：
Are you from Japan?   Yes, I am.／No, I'm not.
Do you live near your school?　Yes, I do.／No, I don't. 
Can you speak French? 　Yes, I can.／No, I can't.
一般疑问句的特性：
1．将陈述句变为一般疑问句时，如句中有be 动词（am/ is/ are）时，可直接将它们提至主语前。
如主语为第一人称，应将其改为第二人称。如：
I'm in Class 2Grade 1． →Are you in Class 2Grade 1﹖
We're watching TV． →Are you watching TV﹖
2．陈述句中有情态动词（can、may、must …）时，也可直接将它们提至主语前，即可成为一般疑问句。如：
He can swim now． →Can he swim now﹖
The children may come with us． → May the children come with us﹖
3．陈述句中只有一个实义动词作谓语且其时态为一般现在时，变为一般疑问句时要在句首加do或does主语后的实义动词用原形。如：
I like these animals． →Do you like these animals﹖
She wants to go to the movies． → Does she want to go to the movies﹖
4．一般疑问句一般读升调(↑)
5．一般疑问句有时不用yes或 no 回答。如：
Are they in town now﹖
I think so.
May I sit here﹖
Certainly．
Does he like soccer﹖
Sorry I don't know．
6. 一般疑问句的第一单词总是虚词,读的时候要读轻声。
陈述句变为一般疑问句技巧：
根据一般疑问句不同的家族，可以用不同的方法将陈述句变为相应的一般疑问句。
1、第一家族：含be动词或情态动词的句子
秘诀：一调二改三问号
一调：即把句中的be或情态动词调到主语前；
二改：改换主语称谓，即将句中的主语Imy minesweourours等。第一人称分别改为相应的第二人称youyour yours等；
三问号：句末的句号改为问号。如：
Eg. I am an English teacher.    →    Are you an English teacher?
Eg. We can speak English fluently.   →    Can you speak English fluently?

2、第二家族：含行为动词（或称为实义动词）的句子
秘诀：一加二改三问号
一加：即在句首加助动词Do或Does；
二改：1、把谓语动词改为原形；2、改换主语称谓（同第一家组）；
三问号：句末的句号改为问号。
Eg. We read English every morning. → Do you read English every morning?
Eg. Tom’s father listens to English on the radio every evening. →Does Tom’s father listen to English on the radio every evening?
特别注意：对于第二家族一定要注意动词的还原，因为时态与数的变化已经体现在助动词上了。

3、加强记忆口诀：
肯变一，并不难，can 或be提在前；
谓语若为行为动，do 或does句首用。

特殊疑问句：
以特殊疑问词开头，对句中某一成分提问的句子叫特殊疑问句。
常用的疑问词有：what、who、whose、which、when、where、how、why等。
特殊疑问句的基本结构是“疑问词+一般疑问句”。
其回答应当是具体的。特殊疑问句句末一般用降调。 
例如：How do I get there? 
            Why not? 
            What about the sports news?
常用疑问词可先分为3种:
疑问代词：
what（什么）
who（谁，作主语）
which（哪个，在一定范围内选择）
whose（谁的，指附属关系）
whom（谁，作宾语）

疑问副词：
when（何时，询问时间）
where（何地，询问地点）
why（为什么，询问原因）
how（如何，询问手段，方式，工具以及程度）

疑问形容词：
what（which，whose）+名词
例词：
what time（什么时候） what colour（什么颜色）... ...
how much（多少） how long（多长）...
特殊疑问句的特点：
一、 特殊的疑问词：
特殊疑问句要由疑问代词或疑问副词开头，询问的内容不同, 使用的疑问词也不同。
我们学过的疑问词有what（询问事物）, how much（询问价格）, what time （询问时间，尤其是点钟）, what kind of（询问种类）, why（询问原因），who（询问人）, where（询问地点） 等等。如：
—What is this? 这是什么？
—It's a key. 这是一把钥匙。
—How much is it? 这个多少钱？
—It's twenty dollars. 二十美元。
—What kind of movies do you like? 你喜欢哪一类型的电影？
—I like action movies. 我喜欢动作片。

二、特殊的语序：
特殊疑问句由疑问词开头，其构成是“疑问词 + 一般疑问句”。如：
What time is it？ 现在几点钟？
Who is your teacher? 谁是你的老师？
特殊疑问句有两种语序：
1．如疑问词作主语或主语的定语，即对主语或主语的定语提问，其语序是陈述句的语序：
Who is singing in the room﹖
whose bike is broken﹖
2．如疑问词作其他成分，即对其他成分提问，其语序是：
特殊疑问词+一般疑问句(特殊疑问词+be/助动词/情态动词+主语+谓语)
What does she like?
What class are you in﹖
Where are you from﹖
What time does he get up every morning﹖
How do you know﹖
 
三、特殊的答语：
特殊疑问句不能用yes, no来回答，而应根据它所询问的内容直接做出回答才行。如：
— What time is it, please? 请问几点了？
— It's 7:30. 七点半了。
— Where are they? 他们在哪儿？
—They're in the playground. 他们在操场上。
—What's your favorite subject? 你最喜爱的科目是什么？
—English. 英语。

四、 特殊的语调：
一般情况下，特殊疑问句要用降调（↘）来读。如：
Who's ↘that?
How old is↘Jack?

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

倒装句：
为了强调、突出等语的目的而颠倒原有语序的句式叫做倒装句。在倒装句中，颠倒了的成分可以恢复原位而句意基本不变，句法成分不变。

倒装句使用情况：
A. 在疑问句中
各种疑问句一般地说都是倒装语序。例如：
Will they come to see us this weekend ? 这个周末他们将来看我们吗？
Are you talking about the film you saw last Monday ?
你们是在谈论你们上周一看的那部电影吗？
Can you speak another foreign language except English?
除开英语，你还能说另一种外语吗？
Where did you buy the dictionary, in the book store nearby or in Xinhua bookstore?
你在哪儿买的这本词典，是在附近的书店还是在新华书店？
She is not a student, isn't she ? 她不是个学生，对吗？

B. 在感叹句中
某些感叹句也用倒装语序。例如：
Isn't it a beautiful garden ! 多么美丽的花园啊！
What a beautiful garden it is ! 多么美丽的花园啊！
（在这种句式中，主语在谓语之前，属于自然语序。对于主语和谓语而言，语序没有倒装。）
Have you ever seen such a naughty kid like him ! 你见过那个孩子像他这么调皮！

C. 在陈述句中
陈述句在一般情况下用自然语序；但由于英语语法的某些原因，陈述句也要使用倒装语序。这些原因大致可以归纳如下：
1) 为了避免句子部分内容不必要的重复，常用"so + be动词（助动词、情态动词）+主语"或"neither / nor + be动词（助动词、情态动词）+主语"的倒装句式。
其中第一个句式表示"与前面所述的肯定情况相同"， 第二个句式表示"与前面所述的否定情况相同"。例如：
His brother is a college student; so is mine.
他弟弟是大学生，我弟弟也是。
His brother is not a college student; nor is min .
他弟弟不是大学生，我弟弟也不是。
He used to have his further study abroad; so did I.
他曾去国外深造过，我也去过。
He didn't use to have his further study abroad; neither did I.
他没去国外深造过，我也没有。
One of my friends can speak three foreign languages; so can his wife.
我的一个朋友会说三门外国语，他的妻子也会。
One of my friends cannot speak three foreign languages; neither can his wife .
我的一个朋友不会说三门外国语，他的妻子也不会。
They are now preparing for their final examinations; so are we .
他们正在为期末考试作准备，我们也一样。
They are not now preparing for their final examinations; nor are we .
他们没在为期末考试作准备，我们也没有。

2）具有否定意义的词或短语置于句首时（除否定词修饰主语外），句子一般要写成部分倒装句。
这类词或短语常见的有：
not, never, seldom, hardly, rarely, scarcely, by no means, under no circumstances, in no way, at no time, no sooner … (than), hardly … (when), not only … (but also), not until… ,等。例如：
Hardly had she sat down when she heard someone knocking at the door .
她还没来得及坐下来，就听见有人敲门。
Not until twelve o'clock did he go to bed last night .
他昨晚直到十二点钟才睡觉。
Never have my sisters been to Hong Kong before .
我的妹妹们以前从未去过香港。
No sooner had I returned home from New Zealand than I bought a house and went to live there.
我从新西兰一回国，就买了一栋房子并在那儿住下了。
So far as I know, seldom does Mary come back to see her mother.
就我所知，玛利几乎很难回来看她妈妈。
Scarcely a drop of rain fell here last fall . （否定词修饰主语时，句子不用倒装。）
去年秋天，这儿几乎没下一滴雨。

3）当so, often, only等表示程度、频率的副词放在句首时，句子一般要倒装。例如：Only in this way can you come up with a solution to the problem.
只有这样，你才有可能想出解决这个问题的办法。
So serious was the situation that everybody faced a test.
形势如此地严峻，每个人都面临着一场考验。
So hard did he overwork that he fell ill at last. 他太操劳过度以致最后病倒了。

4）当there, here, then, now等副词在句首，且谓语是come, go, be等动词时，句子一般要全部倒装。
其意义在于引起他人的注意。如果这类句子的主语是代词，则不用写成倒装句。例如：
Now, here goes the story.这个故事是这样的。
Look, there comes the taxi.瞧，出租车过来了。
Then came another question.然后又一个问题提出来了。
Then followed the four-year War of Liberation.接下来是四年的解放战争。

5) 当out, in, away, up, bang等表示方位或拟声词放在句首时，句子一般要全部倒装。
这类句子比自然语序的句子更为生动、形象。但如果这类句子的主语是代词，则不用写成倒装句。例如：
Bang goes my ace.我砰地一下打出了"爱司"。
Away flew the bird.那鸟飞走了。
Suddenly, in came a man with a mask on his face.突然进来一个蒙着面具的人。

6) 其他情况还有：省略了if的虚拟条件句、某些表示祝愿的句子、以及某些让步状语从句，等等也要用倒装句式。例如：
（省略了if的虚拟条件句）Had they not helped us, we could not have done it so successfully.
如果没有他们的帮助，我们不可能把那件事办的如此成功。
Should he come, say "Nobody in" to him.
万一他来了,对他说："公司没人。"
（某些表示祝愿的句子）May our friendship last forever.
愿我们的友谊常存！
May your company become prosperous.
祝贵公司生意兴隆！
（某些让步状语从句）Try as I might, I couldn't lift the stone.无论我使多大的劲，我也无法搬起那块石头。
They said they would follow the Party's lead come what might.
他们说无论发生什么情况，他们都会跟党走的。

7) 由于修辞或是平衡句子的原因也可以用倒装句；也可以不用。这不是一条必须的规定。
Next to this one is another grand hotel which is beautifully decorated .
家饭店隔壁还有一家装修华丽的大饭店。
On either side of the great avenue stood many block buildings.
这条大街的两侧都耸立着许多综合楼。（这类句子也可以不用倒装句。）
"I'm leaving for Beijing tomorrow," said Tom to his mother (OR: Tom said to his mother) .
汤姆对他妈妈说："我明天动身去北京。"
Many block buildings stood on either side of the great avenue.
许多综合楼耸立在这条大街的两侧。
Another grand hotel, which is beautifully decorated, is next to this one .
这家饭店隔壁还有一家大饭店，那家饭店装修十分华丽。

完全倒装与部分倒装:
1.完全倒装（Full Inversion）：又称"全部倒装",是指将句子中的谓语全部置于主语之前。此结构通常只用于一般现在时和一般过去时。
谓语+主语+……
①There be（的各种形式）+主语（+地点或时间状语）
例子：
There was a drop in the temperature.温度下降了
There are brids singing in the tree.鸟儿在树上唱歌。
②副词小品词+谓语动词+名词主语+……
③过去分词或现在分词+be的各种形式+主语+……
2.部分倒装（Partial Inversion）（又称半倒装句）：
指将谓语的一部分如助动词或情态动词倒装至主语之前,而谓语动词无变化。
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。
英语句子的倒装一是由于语法结构的需要而进行的倒装，二是由于修辞的需要而进行的倒装。
前一种情况,倒装是必须的，否则就会出现语法错误；
后一种情况，倒装是选择性的，倒装与否只会产生表达效果上的差异。
倒装的作用:
通常是希望强调句中的某一部分
1. 当以there, here, out , in , up , down, away 等副词开头的句子，为了起到强调的作用，可构成倒装句，只把副词放在句首，主语和谓语位置调换，不加助动词。
Our teacher came in.
In came our teacher.
这种倒装要求：主语必须是名词。主语是人称代词时，主语和谓语语序不变。
Here it is.
Away he went.
这类倒装句式一般只用一般现在时和一般过去时。
Here comes the bus.
Out rushed the boys.

2. how, then, just, often 表示时间的副词放在句首，可构成倒装句，只把副词放在句首，主语和谓语位置调换，不加助动词。
Then came 8 years of the Anti Japanese War.

3. 表地点状语的介词短语放在句首，要用倒装句式，以示强调。
这种倒装句也是主谓直接调换位置，不加助动词did, does或do.
Under a big tree sat a fat man  half asleep.

4. there放在句首时，要用倒装句式。
在“there + be”结构中的谓语动词有时不用be , 而用表示类似“存在”观念的其他不及物动词。如：
live, stand, come, lie, flow, enter, rise 和appear等。
There came shouts for help from the river.
There lies a large wheat field in front of the house.
Many years ago there lived an old man in the wooden house.
In front of the tower flews a stream.

5. so + 动词+主语
neither/ nor + 动词+主语
表示两人的同样一个情况时，只能表示一件事，即上、下句所使用的动词、时态要一致。
否则要用so it is with…
You can ride a bike. So can I .
He has been to Beijing. So have I .
The first one isn’t good, neither is the second.
His uncle is a worker and has been working in the factory for more than ten years. So it is with his aunt.

6. so+ 形容词/副词that 的结构状语从句可以用正常语序表示，也可以把so+形容词/副词放于句首构成倒装。
句型如下： so +形容词/副词+be/助动词/情态动词that +从句。
Light travels so fast that it is difficult for us to imagine its speed.
= So fast does light travel that it is difficult for us to imagine its speed.
So easy was the work that they finished it in a few days.

7. done做形容词在句中做表语时，常把表语放在句首，要用倒装句式。
Gone forever are the days when the Chinese people had to use foreign oil.

8. 否定副词not , never, seldom, nowhere, little , rarely 放于句首时要用倒装句式。
We seldom get up at four in the morning.
= Seldom do we get up at four in the morning.
Not a single word from him could the enemy drag.
Rarely have I heard of such a silly thing.

9. hardly…when; scarcely…when…; no sooner…than… 可以用正常语序 had hardly done when… did 或用倒装句式Hardly had + 主语+ done when… did 句式。
hardly所在的句子用过去完成时。
The bell hardly had rung when the class began.= Hardly had the bell rung when the class began.
No sooner had he arrived in Beijing than he began to work.

10. not only… but also 如连接两个成分时，不用倒装；连接句子时，前面的句子要用倒装。
Not only was everything that he had taken away from him, but also his German citizenship.
Not only is he busy, but also I have a lot of work to do.
Not only does he speak English very well, but also he speaks French well.

11. only 及所修饰的副词、介词短语或状语从句放在句首时，要用：
only+ 状语+ be /助动词/情态动词+主语及其他
Only when he told me the news did I know what had happened.
Only in this way can you make progress in your English.

12. 虚拟语气中的倒装句
If I were you, I would take the job. = Were I you, I would take the job.
