  • 疑问词组
动词不定式:
指由to加上动词原形(而且只能是动词原形)所构成的一种非限定性动词,但在有些情况下to可以省略。
动词不定式在语法功能上可作主语、宾语、宾语补足语、表语、定语和状语。
动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性。
动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出。
这一使动者我们称之为逻辑主语,其形式如下:
时态 主动形式  被动形式 
一般式 (not) to do (not) to be done
完成式 (not) to have done (not) to have been done
进行式 (not) to be doing  
完成进行式 (not) to have been doing  

不定式的用法:
1、不定式作主语
例如:To remember this is very important.
注意:为了避免头重脚轻,在许多情况下,通常都将作主语的不定式置于句子后部,而在句首主语位置使用形式主语it。
例如:It is very important to remember this.
2、不定式作表语
例如:He seems to be ill.
注意:不定式作表语主要有三种情况,一是用于seem, appear, prove等系动词之后的不 定式(尤其是to be),
二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形,
三是表示想法、约定、义务、命令、可能性、命运等,如: 
You are to come when I call.
3、不定式作宾语
例如:I can not afford to buy a car.
注意:
①不定式不仅用作动词的宾语,还可用作个别介词(but, except)的宾语。
例如:I had no choice but to wait.
②当作宾语的不定式后跟有宾语补足语时,通常要用形式宾语it代替不定式,并将真正的宾语不定式置于宾语补足语之后
例如:I find it difficult to learn Japanese well.
4、不定式作宾语补足语
例如:Who taught you to drive?
5、不定式作定语
例如:I have a question to ask you.
注意:有的名词(如way, chance, right等)后用作不定式可换成of doing sth.
如:It is the best way to do (of doing) it.
但是以下名词后接不定式作定语时通常不能换成of doing sth.
attempt  courage  decision  effort  fortune  failure  invitation  wish
6、不定式作状语
例如:I went to France to learn French.
一般过去时:
表示过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为;过去主语所具备的能力和性格。
基本结构:
主语+动词过去式+其他;
否定形式①was/were+not;②在行为动词前加didn't,同时还原行为动词;
一般疑问句Did+主语+do+其他。
一般过去时句法结构:
肯定形式
主语+动词过去式+其他
例句:She often came to help us in those days.
否定形式
①was/were+not;②在行为动词前加didn't,同时还原行为动词
例句:I didn't know you like coffee
一般疑问句
①Did+主语+do+其他? ②WasWere+主语+表语?
例句:Did I do that?
用表格整理如下:
肯定式 疑问式 否定式 疑问否定式
Iworked Did I work? I did not work Did I not work?
He(She,It) worked Did he(she,it) work? He(she,it) did not work Did he(she,it) notwork?
We worked Did we work? We did not work Did we not work?
You worked Did you work? You did not work Did you not work?
They worked Did they work? They did not work Did they not work?
记忆口诀:
一般过去时并不难,过去动作、状态记心间。
动词要用过去式,时间状语句末站。
否定句很简单,didn't 站在动原前,其它部分不要变。
一般疑问句也好变,did放在句子前,主语、动原、其它部分依次站。
特殊疑问句也简单,疑问词加一般疑问句记心间。
最后一条请注意,动词过去式要牢记!

一般过去时中动词过去式变化规则:

结构句型:

1.一般句子
I watched TV last night.
2.一般疑问句
Did you watch TV last night?
3.there be 句型
There was an apple on the table last night.
Was there an apple on the table last night
一般过去时注意事项:
1.注意主句与从句中时态的一致性
如果主句用了过去时,从句中一般也要用过去式,或者过去进行时、过去完成时等。例如:
He believed that he was right. 他相信自己是对的。
I didn’t know you were here. 我不知道你在这儿。
I thought they were with you. 我以为他们和你在一起。

2.在口语中, 一般过去时并不一定指真正的过去,而只是表示一种礼貌性语气。例如:
I wondered (wonder) if you could do me a favor. 不知你可否帮我一个忙。
I wanted (want) to ask if I could borrow your car. 我想问问可否借用你的车。
I hoped (hope) you could (can) give me some advice. 我希望你能帮我出点主意。
Did (Do) you want to see me? 你想见我吗?

3.used to
used to 是一个词组,表示“过去曾经是……而现在已经停止了”的动作。例如:
I used to work fourteen hours a day. 我过去常常一天干十四个小时。(而现在不这样了)
I used to take a walk in the morning.我过去是在早晨散步。(而现在不在早晨散步了)
一般过去式用法:
(1)一般过去时表示在过去某个特定时间发生,也可以表示过去习惯性、经常性的动作。
一般过去时不强调动作对现在的影响,只说明过去的事情。
句式:主语+动词过去式+宾语+其它
I had a word with Julia this morning.今天早晨,我跟茱莉雅说了几句话。
He smoked many cigarettes a day until he gave up. 他没有戒烟的那阵子,抽烟抽得可凶了。

(2) 一般过去时常与表示过去的时间状语或从句连用,如:
yesterday,last week ,in  the  past ,in 1993,at that time,once,during the war,before,a few days ago,when 等等.
(句子中谓语动词是用一般过去时还是用现在完成时,取决于动作是否对现在有影响)。
Have you had your lunch? 你吃过午饭了吗?(你现在不饿吗?)
Yes,I have. 是的,我已经吃过了。(已经吃饱了,不想再吃了。)
When did you have it? 你是什么时候吃的?(关心的是吃的动作发生在何时。)
I had it about ten minutes ago. 我大约是十分钟以前吃的。)
Used to do something 表示过去常做而现在已经停止了的习惯动作。
I used to work fourteen hours a day. 我过去常常一天干十四个小时。
I ate it at 6:45。我在六点四十五分吃了。

(3)带有确定的过去时间状语时,要用过去时。如:
yesterday(昨天)、two days ago…(两天前…… )、last year…(去年…)、the other day(前几天)、
once upon a time(很久以前)、 just now(刚才)、in the old days(过去的日子里)、before liberation(解放前…)、
When I was 8 years old(当我八岁时…)、at+一个时间点
Did you have a party the other day?前几天,你们开了晚会了吗?
Lei Feng was a good soldier.雷锋是个好战士。
注:在谈到已死去的人的情况时,多用过去时。

(4)表示过去连续发生的动作时,要用过去时。这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。
The boy opened his eyes for a moment,looked at the captain,and then died.
那男孩把眼睛张开了一会儿,看看船长,然后就去世了。

(5)表示过去一段时间内经常或反复的动作。常与always,never等连用。
Mrs. Peter always carried an umbrella.彼得太太过去老是带着一把伞。
(只是说明她过去的动作,不表明她现在是否常带着伞。)
比较:
Mrs. Peter always carries an umbrella.彼得太太老是带着伞。
(说明这是她的习惯,表明她现在仍然还习惯总带着一把伞)
Mrs. Peter is always carrying an umbrella.彼得太太 总是带着一把伞。
(表示说话者对这一动作或行为厌烦)
I never drank wine.我以前从不喝酒。
(不涉及到现在,不说明现在是否喝酒)

(6)如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了)
He used to drink alcohol.他过去喝酒。
(意味着他现在不喝酒了。喝酒这个动作终止了)
I used to take a walk in the morning.我过去是在早晨散步。
(意味着现在不在早晨散步了)
比较:
I took a walk in the morning.我曾经在早晨散过步。
(只是说明过去这一动作)

(7)有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时。
I didn''t know you were in Paris.我不知道你在巴黎。
(因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)
I thought you were ill.我以为你病了呢。
(这句话应是在说话之前,我以为你病了。但是现在我知道你没病)
一般过去时三变技巧:
一变:肯定句变为否定句
技巧1.当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如:
I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
技巧2.当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如:
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如:
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.

二变:陈述句变为一般疑问句
技巧1.移动词语的位置。将was,were, could,would,should等移到句首。例如:
He could pack his things himself. → Could he pack his things himself?
技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时,在主语之前加did,动词还原。例如:
Mr Li looked very old. → Did Mr Li look very old?

三变:陈述句变为特殊疑问句
技巧1.确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如:
They gave the concert last night. → When did they give the concert?
技巧2.辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如:
The accident happened near the station. → Where did the accident happen?
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

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。
疑问词组:
即使由疑问词和一些词一起构成的表示疑问的词组。由how/what与另外一个词组成的词组。
例如:
how many (后接可数名词,多少), how much (后接不可数名词,多少), 
how often (表示频率), what if (如果…将会怎么样), 
what about (…怎么样), what time (几点)

与how搭配的疑问词组:

1.How old问年龄、年代。
How old is your friend? 你朋友多大了?
How old is the bridge? 这座桥有多少年代了?
2.How many问可数名词数量。常将可数名词复数紧随其后。如:

3.How much询问不可数名词的数量、物品的价格。
How much money is there in the purse? 钱包里有多少钱?

你每天花多长时间做作业?
5.How soon 对 “in+一段时间 ”提问, 表示“多久之后”。
How soon will you be back? 你多久后回来?
6.How often对表示频率的副词或短语提问。
How often does Mrs. Green go shopping? 格林夫人多久去购一次物?
7.How about用来征求对方意见。
Your father is a worker, how about your mother? 你父亲是工人,你母亲呢?
How about playing games after school this afternoon? 下午放学后做游戏怎么样?
8.How far 问两地间的距离How tall问人(树)的高度;how heavy问重量;how wide问宽;how high可以询问建筑物、山峰高度。
How far is it from the earth to the moon? 从地球到月球有多远?
How tall is Yao Ming? 姚明身高多少?
How heavy is that big box? 那只大箱子有多重?
How wide is the new street? 这条新街有多宽?
