初中英语语法总结
总结是事后对某一阶段的学习、工作或其完成情况加以回顾和分析的一种书面材料,它有助于我们寻找工作和事物发展的规律,从而掌握并运用这些规律,因此我们需要回头归纳,写一份总结了。那么总结应该包括什么内容呢?下面是小编为大家收集的初中英语语法总结,仅供参考,大家一起来看看吧。
初中英语语法总结1
冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面帮助指明名词的含义。冠词分为不定冠词a(an)和定冠词the两种。不定冠词仅用在单数可数名词前面,表示“一”的意义,但不强调数目观念,只表示名词为不特定者。定冠词则表示名词为特定者,表示“这”、“那”、“这些”、“那些”的意思,在可数的单复数名词或不可数名词前面都可以用。
I不定冠词
We need an apple and a knife.
我们需要一个苹果和一把刀子。
1.a和an的区别
不定冠词有a[+]和an[+Q]两种形式,a用于辅音(不是辅音字母)开头的`词前。an用于元音(不是元音字母)开头的词前。
a boy, a university, a European country
u是元音字母,但发音是[U(],是辅音。
an hour,an honor,an island
h是辅音字母,但它不发音,它的音标是是元音。
an elephant,an umbrella,an egg
2(1)不定冠词的用法
①泛指—类人或物。
eg. This is a pencil case.
②指不具体的某个人或物。
eg. I met an old man On my way home.
③用在序数词前,相当于another.
eg. There’s a third boy near the shop.
④表示“每—(个)”,相当于every.
eg. They have music lessons twice a week.
必背!
give a lesson take a bath have a rest
教(一堂)课洗(个)澡休息
have a talk have a fever have a good time
听报告发烧过得愉快
have(take)a walk have a headache have a nice trip
散步头疼旅途愉快
a lot of, a lot, a little, a few, a glass of, such a/an, have a word with, have a look, have a try, have a swim, a quarter, half an hour, three times a day, have a talk, give a talk, ten Yuan a kilo
(2)不定冠词的位置
①不定冠词—般放在所修饰的单数可数名词前。
eg, a bike, an egg
②当名词被such, what, many修饰时,不定冠词放在这些词之后。
eg.It took me half an hour to finish my homework.
He left in such a hurry that he forgot to close the door.
What a dangerous job it is!
Many a man has gone to the big cities for work.
③当名词前的形容词前有so, how, too等词时,不定冠词应放在形容词之后。
Eg. She was so nice a girl that she took the blind man to the station.
How nice a film this is!
④当名词前面有形容词和quite, rather, very时,不定冠词放在quite, rather之后,very之前。
eg.It is quite a good book.
That is rather a useful too1.
This is a very interesting story.
初中英语语法总结2
【—need】didn't need to do的意思是过去不必做某事, 事实上也没做。而needn't have done则表示过去不必做某事, 但事实上做了。
初中英语语法大全:need "不必做"和"本不该做"
didn't need to do表示: 过去不必做某事, 事实上也没做。.
needn't have done表示: 过去不必做某事, 但事实上做了。
John went to the station with the car to meet Mary, so she didn't need to walk back home. 约翰开车去车站接玛丽,所以她不必步行回家了。
John went to the station with the car to meet Mary, so she needn't have walked back home. 约翰开车去车站接玛丽,所以她本不必步行回家了。 (Mary步行回家,没有遇上John的.车。)
典型例题
There was plenty of time. She ___.
A. mustn't have hurried B. couldn't have hurried C. must not hurry D. needn't have hurried
答案D。needn't have done. 意为 "本不必",即已经做了某事,而时实际上不必要。
Mustn't have done 用法不正确,对过去发生的事情进行否定性推断应为couldn't have done, "不可能已经"。 must not do 不可以(用于一般现在时)。

数词时刻的'表达法:
一、 整点法:如果时间是整点,就用“钟点数+o’clock”来表示。o’clock可省略。如:8:00可读作eight
o’clock或eight
二、顺读法:顺读法,也叫直接读法,此方法用于既有钟点数,又有分钟数的时间,通常先读“钟点数”,再读分钟数。如:7:20读作seven-twenty
三、倒读法:此方法是“先读分钟数”,再读“钟点数”,使用此方法要注意两点:
1、如果分钟数在30以内,就用“分钟数+past+钟点数”表示,介词past意为“过”。如:6:10读作ten past six.
2、当分钟数正好是“三十分钟”时,可用“顺读法”中的“钟点数+thirty”,也可用“half+past+钟点数”.如:7:30可读作seven
thirty 或 half past seven.
3、如果分钟数超过30,则用“(60-分钟数)+ to +(钟点数 + 1)”来表示,介词to 为“差”的意思。如:6:35读作twenty-five
to seven (差二十五分钟到七点)
在“倒读法”中,当分钟数涉及到“15分钟”时,一般不用fifteen,而用a quarter(一刻钟)来表示。如:10:15读作a quarter
past ten (一般不读 fifteen past ten)
初中英语语法总结4
每年的中考试卷中,“句型转换”题所占分值较大,是为了全面考查学生在初中阶段所学的词汇(同义或反义)、短语、句型和语法等方面的知识及其它的之间的灵活运用能力。
Ⅰ.题型介绍
所谓“句型转换”就是先给一个完整的句子A,再根据括号内的要求(有时没有明确,须自己观察),在第二个句子B的空白处填上适当的词来完成的句型转换。
Ⅱ.题型分类
从形式上看,有如下几种形式:①某一词或词组的转换;②词组与句子的转换;③同义句型的转换;④为纠正常犯语言错误而设计的题目。
从内容上看,此题型涉及的面较广,主要有:①句子功能方面的转换。包括陈述句(肯定与否定)、四种题疑问句、祈使句、感叹句的转换;②句子结构方面的转换。即简单句、复合句、并列句之间的转换;③语态的转换。即主动语态与被动语态之间的转换;④常用句型与词汇手段的转换。
Ⅲ.具体分类如下
一、陈述句与疑问句、祈使句、感叹句间的转换
1、陈述句中肯定句变为否定句,大部分是用not来改变谓语结构,但也有借用否定意义的词,如nothing, nobody, none, neither, little, few, never, hardly等,例如:
A:Tom does well in maths.
B:Tom doesn't do in maths.
A:He has much to do.
B:He has nothing to do.
A:All of my classmates like art.
B:None of my classmates likes art.
2、改为疑问句。根据上下句的结构和词的减少,来判断变为哪一种形式的疑问句。例如:
A:My brother often has breakfast at school.
B: Does your brother often have breakfast at school?
A:Tom's already weak in English.
B:Tom's already weak in English, isn't he ?
A:The red light changes every two minutes.
B:How often does the red light change?
3、改为感叹句。根据所给的句子结构和单词的词性,来确定使用哪一种感叹句的形式,例如:
A:This is an interesting book.
B:What an interesting book this is!
或 How interesting this book is!
二、同义句转换。
根据上句,写出一个意思相同(或相近)的下句,此类形式繁多,内容复杂,涉及面广,归类如下:
1、同义词或词组之间的转换。(通常上下句时态保持一致)。
常见的同义词或词组有:(1)四个“花费”(spend-take-cost-take);(2)三个“到达”(get to-reach-arrive in/at);(3)四个“收到…来信”(hear from-get a letter from-receive a letter from-have a letter from);(4)两个“擅长于…”(be good at -do well in);(5)两个“有空”(be free-have time);(6)三个“入睡”(go to sleep-get to sleep-fall asleep);(7)两个“玩得开心”(enjoy oneself-have a good time);(8)“给…打电话”(call sb-telephone sb-ring sb. a call-make a telephone to sb.)(9)“飞往…”(fly to…-go to…by air/plane)(10)“自学”(teach oneself-learn…by oneself)(11)在…方面帮助help…with…-help… (to)do…(12)在…差be weak in…-do badly in…(13)能/会…can-be able to(14)更喜欢…like…better than…-prefer…to…(15)充满了…be full of…-be filled with…(16)放弃干…give up doing…-stop doing…(17)不再… no longer-not …any longer(18)照顾/保管 take care of…-look after(19)展览 on show-on display(20)阻止…干…stop…from doing-keep/prevent…from doing…(21)由于 thanks to-because of…(22)举手hands up-put up one's hands(23)最后,终于at last-in the end(24)与…不同 be different from…-be not the same as…(25)从…借入… borrow…from…-lend…to…(26)乘公汽/火车/的士 go to…by bus/train/taxi-take a bus /train/taxi to…(27)乘自行车去… go to…by bike-ride a bike to…(28)为…感到自豪 be proud of…-be the pride of…(29)步行去… walk to…-go to…on foot (30)独自地by oneself -alone等。例如:
A:The children had a good time in the park.
B:The children enjoyed themselves in the park.
2、同义句型之间的转化。常见的同义句型有①It seems that 从句→Somebody seems(to be)+adj/n ②It's kind of sb. to do…→Somebody is kind to do… ③What does…mean?→What do you mean by…? 或What's the meaning of…?④There is something wrong with…→Something is wrong with… ⑤not…until…与when/after/before引导的时间状语从句的转换 ⑥What's wrong with…?→What's the matter with…? ⑦How is…?→What's…like…?⑧How do you like…?→What do you think of?⑧It's time that…→It's time for sb. to do…⑨It's said that…→People say that…⑩Can I help you? →What can I do for you?
例如:
A:I went to bed after I finished my homework.
B:I didn't go to bed until I finished my homework.
3、if引导的条件状语从句的转化。例如:
A:If it doesn't rain tomorrow, they'll go to the park.
B:Unless it rains tomorrow, they'll go to the park.
A:If you don't hurry, you'll be late.
B:Hurry up, or you'll be late.
A:Fish can't live if there is no water.
B:Fish can't live without water.
4、现在完成时态中的一句多译。在现在完成时态中,结束性动词不能与时间段连用,必须改成相应的延续性动词。常见的动词转换有:buy-have, borrow-keep, die-be dead, open-be open, join-be in+组织/be a +成员, begin-be on, leave-be away from, close-be closed, arrive in/ get to/ come/go to-be in/at, finsh-be over, go to sleep-be asleep,get up-be up.
例如:The old man died five months ago.
The old man has been dead since five months ago.
The old man has been dead for five months.
It's five months since the old man died.
Five months has passed since the old man died.
5、简单句与复合句之间的转换。
①含宾语从句的复合句与简单句的转换。例如:
A:I saw they were playing football on the playground.
B:I saw them playing football on the playground.
A:The teacher found that she was very clever.
B:The teacher found her very clever.
A:He found that it was hard to learn English well.
B:He found it hard to learn English well.
A:We are sure that we will win to first match.
B:We are sure to win to first match.
由疑问代词/副词引导的宾语从句可转化为“疑问句+不定式”结构。例如:
A:Could you tell me how I can get to the railway station?
B:Could you tell me how to get to the railway station?
A:We don't know what we should do next.
B:We don't know what to do next.
②由when/after/before/while/since/until引导的时间状语从句可转化为when/after/before/while/sine/until + doing…
例如:
A:They went home after they finished their work.
B:The went home after finishing their work.
A:Mr Smith has taught English since he came to China.
B:Mr Smith has taught English since coming to China.
When sb. +be+数词+years old→at the age of+岁数
A:When he was twelve years old, Edison started writing his own newspaper.
B:At the age of twelve, Edison started writing his own newspaper.
③由so…that…引导的结果状语从句可转化为too…to do或…enough to do……例如:
A:The box is so heavy that I can't carry it.
B:The box is too heavy for me to carry.
或:The box isn't light enough for me to carry.
A:The child is so old that he can go to school.
B:The child is old enough to go to school.
④由so that 引导的目的状语从句可转化为in order to do例如:
A:My father got up early this morning so that he could catch the early bus.
B:My father got up early this morning in order to catch the early bus.
⑤由because 引导的原因状语从句可转化为because of…例如:
A:We didn't go to the park because it rained.
B:We didn't go to the park because of the rain.
⑥定语从句可以转化为介词短语或分词短语。例如:
A:The man who is on the bike is Jim.
B:The man on the bike is Jim.
A:The man who is driving the red car is my boss.
B:The man driving the red car is my boss.
A:The girl who is called Mary is my sister.
B:The girl called Mary is my sister.
6、用并列连词neither…nor;either…or…;both…and…;not only…but also…连句。例如:
A:I haven't seen a TV play for long, and Lily hasn't either.
B:Neither I nor Lily has seen a TV play for long.
A:Tom is good at maths, and he is good at French, too.
B:Tom is good at both maths and French.
neither…nor…, either…or…和not only…but also…连接两个主语时,谓语动词依靠近它的主语而定,即“就近原则”,但是both…and用来连接两个主语时,谓语复数。
7、主动语与被动语态的互变。
“主动”变“被动”实行“三变二不变”原则。“三变”即是主语,谓语和宾语的变化,“二不变”即时态不变,句式不变。例如:
A:They make watches in the town.
B:Watches are made by them in the town.
A:I can finish the work before eight.
B:The work can be finished(by me)before eight.
A:Do they grow rice in South China?
B:Is rice grown in South China?
注:使役性动词make或感观性动词see/watch/look at/hear/listen to/feel在主动语态中所带省to的不定式宾补变为被动语态时,必须加上to.
A:I saw him take your umbrella.
B:He was seen to take your umbrella.
8、形容词、副词二级之间的转化,例如
A:Chinese is the most important subject of all.
B:Chinese is more important than any other subject.
A:This exercise is easier than the other two.
B:This exercise is the easiest of the three.
Ⅵ.解题指导
要做好句型转换题,必须注意如下几点:
1、注重掌握教材中的基本句和同一句子英语的不同结构表达技巧。
2、弄清题意,明确题目考查点,了解题目所给句子与答句之间的关系。
3、注意从多角度,全方位考虑问题,突破难点,注意复查,看是否按要求完成了转换。
通过上述的归纳和指导,可以理清学生的“依章办事”的解题思路,养成“有条不紊”的解题习惯,培养多角度思维解题的能力,从而达到提高学习效率的目的。

同义句转换的九种类型
同义句转换题是近几年中考英语的一个常考题型,其出题形式通常是同时给出两个句子,第一句完整,第二句中设有几处空格,要求考生填入适当的词或词组,使第二句的意思与第一句意思相同。它综合考查考生的语法、词汇、短语或习惯用语和句型结构等知识,要求运用所学的词汇、语法知识和句型结构填写句子,使句子结构完整、逻辑合理、语法知识无误、意思与所给句子相同。通过对近几年的中考英语试题中同义句转换题的分析,我们发现中考英语同义句转换题主要考查以下几个方面:
一、运用同义词(组)进行转换
用同义词或同义词组对原句中的某些词或词组进行替换,注意转换后的词或词组的词形变化要与句子其他成分相适应。如:
1. That day we could see flowers here and there.
That day we could see flowers __________.
分析:答案为everywhere。everywhere与here and there都表示“到处”。
2. The teacher always takes good care of the children in the school.
The teacher always_______ ______the children well in the school.
分析:答案为looks after。take good care of与look after…well都表示“好好照顾”。
二、运用反义词(组)的否定式进行转换
即用反义词或词组的否定式表达与原句相同的意思,主要考查学生对反义词(词组)的积累和换位思维的能力。如:
1. It’s clear that this visit is different from last time.
It’s clear that this visit is not the___ ___last time.
分析:答案为same as。be different from意为“与……不同”;the same as意为“与……相同”,其否定式与be different from同义。
2. I think wealth is less important than health.
I ___ think wealth is ___ important than health.
分析:答案为don’t,more。less important的意思是“没有(不及)……重要”;more important的意思是“(比)……更重要”,该结构与not连用,则表示“不比……更重要”。
另外,有的反义词即使不与否定词连用,而只需改变句子结构也可构成同义句。如:
He lent some money to his friend.
He friend ___ some money ___ him.
分析:答案为borrowed,from。borrow…from意为“向……借……”;lend…to意为“把……借给……”。两个结构意思相反,但若变换“借出者”与“借入者”的位置,则可转换为同义句。
三、运用不同语态进行转换
即运用主动语态与被动语态的变化来转换同义词,但此时要特别注意时态、动词一致性。如:
1. Everyone should give back his library books on time.
Library books should____ ____ ____ on time.
分析:答案为be given back。被动句中含有情态动词should,因此助动词用be。
2. It is widely accepted that more people use computers in the world today.
Computers ____ widely ___ in the world today.
分析:答案为are,used。computers是复数名词,助动词用are。
四、非延续性动词与延续性动词的相互转换
即非延续性动词与延续性动词进行转换,此时往往会涉及时态的变化。如:
1. The manager left two hours ago.
The manager _____ ____ ____ for two hours.
分析:答案为has been away。leave为非延续性动词,不能与for two hours这样的一段时间连用,而改成be away这样的延续性动词后,则可连用一段时间。
2. The film began five minutes ago.
The film has been _____ _____ five minutes.
分析:答案为on for。has been提示时态是现在完成时态,“for+时间段”表示“持续(一段时间)”,常用在含有现在完成时态的句子里。
3. Mr Li joined the Party twenty years ago.
Mr Li _____ _____ _____ the Party for twenty years.
答案:has been in。短暂动词join,意为“参加、加入(组织,政党)”,不能与延续时间状语连用,与延续性时间状语连用时,将join改成be in或be a member in…。
五、运用不同引语进行转换
即将直接引语变为间接引语或将间接引语转换成直接引语。此时还要注意相关时态、人称、动词、状语等相应的变化。如:
1. “I’ve found my wallet,” he said to me.
He _________ me that he _________ _________ his wallet.
分析:答案为told,had found。此题是将直接引语转换成间接引语。
2. “Did you see her last week?” he said.
He _______ _______ I had seen her the week _______.
分析:答案为asked if/ whether, before。此题是将疑问句的直接引语转换成间接引语。
六、运用简单句与复合句之间的转换
即将简单句变成同义的复合句或将复合句变成同义的简单句。如:
1. We didn’t go out for a walk because it was raining.
We didn’t go out for a walk _______ _______ the rain.
分析:答案为because of。将原因状语从句because it was raining改为表示原因的介词短语because of the rain。
2. He was so excited that he couldn’t go to sleep.
He was ______ ______ ______ go to sleep.
分析:答案为too excited to。将so…that…换成too…to…结构,原句的that从句为结果状语从句,改写句中的不定式仍表结果。
3. Now I will show you how to do the work.
Now I will show you ______ ______ ______ do the work.
分析:答案为how you can。即将原句中的“疑问词+不定式”结构转换成宾语从句。
4. You should put them back after you use them.
You should put them back _____ _____ them.
分析:答案为after using。即将after引导的状语从句改写为after引导的介词短语。
七、运用并列句与复合句之间的转换
即将并列句变成同义的复合句或将复合句变成同义的并列句。如:
1. Come on, or we’ll miss the early bus.
____ we ____ hurry, we’ll miss the early bus.
分析:答案为If,don’t。if引导条件状语从句。
2. The man gave us a talk last week. Now he will give us another talk this week.
The man _____ gave us a talk last week _____ _____ us another talk this week.
分析:答案为who/ that,will give。who/ that gave us a talk last week为定语从句,修饰先行词the man。
八、运用关联连词连接或合并句子
即运用关联连词both…and…,neither…nor…,either…or…,not only…but also…等将两个简单句合并为一个简单句。此时要注意的是,both…and…连接两个主语时,谓语总是用复数,而neither…nor…,either…or…,not only…but also…连接两个主语时,谓语动词通常应与靠近的主语保持一致。如:
1. Tom can’t speak Japanese well and Jim can’t, either.
______ Tom ______ Jim can speak Japanese well.
分析:答案填Neither,nor。neither…nor…表示“……和……(两者)都不”,刚好与原句的两个否定结构的意思相吻合。
2. Alice has read the book and Peter has read it, too.
______ Alice ______ Peter have read the book.
分析:答案为Both,and。both…and…的意思是“……和……(两者)都”。
3. This store sells men’s shoes, and it also sells men’s clothes.
This store sells ______ ______ men’s shoes ______ ______ men’s clothes.
分析:答案为not only,but also。表示“不仅……而且……”之意。
九、利用某些典型句式或结构进行转换
这类典型结构如so…that…,too…to…,enough to,not…until…,so do I等。如:
1. Jim wants to go boating and his parents want to go boating, too.
Jim wants to go boating, and ______ ______ his parents.
分析:答案为so do。句意为“……他的父母也一样(一样想去)”。
2. John went to bed after he finished his homework.
John ______ go to bed ______ he finished his homework.
分析:答案为didn’t,until。not…until意为“直到……才”。

名词
名词的可数与不可数
可数名词指表示的人或事物可以用数来计量,它有单数与复数两种形式。不可数名词指所表示的事物不能用数来计量。物质名词与抽象名词一般无法用数目,来统计,都成为不可数名词。
不可数名词前一般不能用冠词a、an来表示数量,没有复数形式。要表示“一个……”这一概念,就须加a piece
of这一类短语。要注意许多名词在汉语里看来是可数名词,在英语里却不可数。如chalk,paper,bread,rice,grass,news等。
名词复数的规则变化
A.一般情况下加-s。
B.以s, x, ch, sh, 结尾的加-es

如This is Lucy and Licy’ s room.These are Kate's and jack’ s rooms.
C. 如果是通过在词尾加—s构成的复数形式的名词,只加’。如the students’ books,the girls’ blouses
(另外名词+of+名词名词是有生命的,我们就用’s结构来表示所有关系。如果名词所表示的事物是无生命的,我们就要用名词+of+名词的结构来表示所有关系。)

初中英语语法总结6
关系代词在定语从句中作主语、宾语、表语、定语等。关系代词的三个作用代替先行词,在定语从句中作某种成分,连接先行词与定语从句。引导定语从句的关系代词有who,whom,whose,that,which。
关系代词who,whom的用法
关系代词who和whom用来指人。先行词是表示人的名词或代词,在从句中作主语时用关系词who,作宾语时用关系词whom或who。在现代英语中常常用who代替whom。如
This is the man who helped me yesterday.这就是昨天帮助我的那个人。(作主语)
The teacher who/whom you want to see is coming.你要见的老师来了。(作see的宾语)
注意
①关系词在从句中作宾语时,常常被省略。如
The man you talked about is our headmaster.你们谈论的那个人是我们的校长。
②介词后的.宾语只能用关系词whom,不可用关系词who。如
The man to whom you spoke just now is an actor.刚才和你说话的那个人是个演员。
关系代词that的用法
关系代词that既可用来指人,也可用来指物,指人时可代替关系词who、whom,指物时可代替关系词which。that在从句中可作主语或宾语,还可作表语;作宾语或表语时可省略;作介词宾语时,介词不可提到that之前,否则需要用关系词who或which替代。如
Who is the person that/who is making the lecture?正在做演讲的那个人是谁?
Who is the man that/whom they are talking about?他们正在谈论的那个人是谁?
You can never get the time that/which is lost.你永远也找不回来失去的时间。
关系代词which的用法
关系代词which用来指物,在从句中作主语、宾语。which引导定语从句有时可以与that互换使用;作宾语时可以省略。如
Here is the coat which/that will be made to you.这是一件做给你的衣服。(作主语)
This is the factory (which/that )we visited last
year.这就是我们去年参观的那家工厂。(作visited的宾语,可以省略)

初中英语语法总结7
I.要点
表示说的话不是事实,或者是不可能发生的情况,而是一种愿望、建议或与事实相反的假设等。一般常用于正式的书面语中。
1、虚拟语气的构成
如:与现在事实相反
If I had more time, I should study German.(fact:I have no more time, so I shall not study German. )
If she were not so busy, she would attend the meeting this afternoon.(fact:she is very busy, so she will not attend the meeting this afternoon.)
If they didn’t take physical exercises every day, they wouldn’t be so healthy.(fact: they take physical exercises every day, so they are very healthy.)
与过去事实相反:
I would have checked my paper again if I had had more time at yesterday’s examination.(fact:I had no more time at yesterday’s exam, so I didn’t check my paper again)
You would have already recovered from his illness if he had seen the doctor in good time.(fact: He didn’t see the doctor in good time ,so he hasn’t recovered from his illness )
与将来事实相反:
If it rains tomorrow, our picnic will be put off.(The weather has been changeable these days.)
If it rained tomorrow, our picnic would be put off.( The weather has beenvery good these days.)
If it should rain tomorrow, our picnic would be put off.(That would be out of our expectation.)
If it were to rain tomorrow, our picnic would be put off. (条件从句谓语动词用were to +动词原形,表示下雨的可能性极小。Were to rain和should rain都表示“出乎意料之外”,但were to加强表示“当初没想到以后的事”)
注:
(1)如果条件从句谓语动词包含有were或had, should, could有时可将if省去,但要倒装。如:
Had you (If you had) invited us, we would have come to your party.
(2)混合时间条件句的用法:
有时条件从句的动作和主句动作发生的时间不一致。这时动词的形式,应根据它所要表达的具体时间来决定用什么形式。
1) If she hadn’t trained so hard, she wouldn’t be run so fast.(从句叙述过去,主句叙述现在。)
(fact: she has trained very hard, so she would able to run fast.)
2)You would speak English well enough if you had practised reading and speaking it every day.(主句叙述现在,从句叙述过去)
(fact: You didn’t practice (hasn’t practiced ) reading and speaking it every day, so you can’t speak English well enough.)
(3)在其他状语从句中的.用法
主要用于由as if (as though)引导的比较状语从句,从句中谓语动词一般用“动词的过去式(be变were )或had +过去分词。”如:
She looked as if she were ill.(实际上她没有病,在这里用虚拟语气补语比喻她精神不佳)
Xiao Liu speaks English so well as if he had studied in England.(这里用虚拟语气表现他的英语说得好)
2、虚拟语气在各种从句的应用
(1)在主语从句中用来表示惊奇、惋惜、理应如此等,其谓语形式是"should(可省) +动词原形",常用于以下三种句型中。
句型一:It is necessary (important, natural, strange, etc) that…
句型二:It is a pity (a shame, no wonder, etc) that…
句型三:It is suggested (requested, proposed, desired, etc) that…
如:It is strange that he (should) have done that.
It is a pity that he (should) be so careless.
It is requested that we (should) be so careless.
(2)在宾语从句中用于suggest, propose, move, insist, desire, demand, request, order, command等动词后的宾语从句中,表间接的命令和建议。其谓语形式是"(should)+动词原形"。如:
I suggest that we (should) go swimming.
(3)在表语从句中,表示间接的命令,要求、请求、建议、决定等,主句中的主语通常是suggestion, proposal, request, orders, idea等。从句谓语形式是"(should)+动词原形"。如:
His suggestion is that we (should) leave at once.
(4)在同位语从句中,谓语形式是"(should)+动词原形"。如:
We received order that the work be done at once.
(5)在It is time that…句型中,其谓语动词形式是"动词的过去式"或"should +动词原形",should不可省。如:

初中英语语法总结9
常用动词注意事荐
动词注意点
一、主动表被动的情况
感观系动词,look, seem, sound, feel, smell, taste等
eg. The fish tastes nice.
measure, weigh等表示度量的动词。
eg. The elephant weights nearly a ton.
wash, clean, open, sell, read, last, write, steer等不及物动词可以表示被动意义。eg. The ship steer easily.
二、被动句表示主动含义。
She was dressed in a red skirt.
此类动词常见于dress, seat, devote, adapt, accustom等后面可以接反身代词的动词。
二、时态,语态
用进行时表示一种情绪。
She is always helping others.(表赞扬)
The man is always smoking in the office, which offends others very much.
一般过去时表示某一动作已完成,过去进行时表示动作可能未完成。
He wrote a letter yesterday morning.(信已写完)
He was writing a letter yesterday evening. (信可能还未写完)
现在完成时可表示动作持续至今,一般过去时则表示动作已结束,并不强调对现在造成的影响或结果。
I have lived in this street.(我一直住这条街上)
I lived in this street.(我曾住在这条街上)
表示几个连续动作时,尽管有先后,仍要用相同时态。
He came into the classroom, put down the book and wrote a few words on the blackboard.
在条件和时间状语从句中常用一般时表示将来。
叙述过去发生的某件事情常用一般过去时,表示过去某个时间或动作之后发生的事情才用过去将来时,过去某个时刻/段内正发生的事情,才用过去进行时,过去某个时间或动作之前发生的事情才用过去完成时。因此找准时间的参照点,是正确运用时态的关键。
罗列并熟记各种时态的被动形式。
三.动词的类别与特征中的注意点
兼作Vt., Vi.的动词
(1)对兼作Vt., Vi.的动词,要注意根据不同的`情况选择使用。
The children are flying their kites in the square.( Vt.)
We saw a plane flying high up in the sky.( Vi.)
(2)有些动词后跟从句时为Vt.,其它情况为Vi.,但意义基本不变。典型的有wonder, think, insist, agree,等。
The headmaster insisted that the students should wear school uniforms .
The headmaster insisted on the students wearing school uniforms.
(3)有些动词在Vt. Vi.之间,意义有所不同。如run, stand, lie等
She stood alone under the tree.
I can’t stand such cold weather.
常用的双宾动词有give, teach, lend, bring, explain, send, offer, pay, sell, buy, tell, show, write, ask, wish, read等,这些动词都带有一定的趋向性。因此转换成带介词的情况时,常可用for , to来转换。
注意explain sth. to sb.=explain to sb. sth., describe sth. to sb.=describe to sb. sth.
带宾补的动词,注意宾补的逻辑主语是动词宾语
宾补常是名词、形容词、介词短语,副词和非谓语动词等。常见的此类动词有make, have, let, get, keep, find, see, feel, notice等,但要注意不同的动词有不同的接法。
He kept the children (keep不能用不定式作宾补)
Make…do, have…do/doing/done,get…to do/done, find…doing/done, leave…to do/doing/介词短语/ see…doing/do/done
后面常接-ing的动词及短语suggest, finish, avoid, can’t help, mind, need, enjoy, require, postpone, delay, practice, fancy, excuse, pardon, advise, consider, deny, admit, endure, escape, miss, appreciate, dislike, have a good time doing, put off, call off, give up
有些动词后面接to do和-ing时意义基本相同,而有的则完全不同,要注意
Love, like, hate, forget, remember, stop, begin, start, continue, prefer, regret, intend, mean, want, need, require, neglect, try, deserve, can’t bear等
注意状态动词和动态动词的选用
Mother asked the son to notice his manners at the party. (notice就改为mind)
再如listen/hear, look/see, look for/find, advise/persuade, marry/be married, join/be in等。
注意have表“有”时,及系动词一般不能用进行时态。
注意表示“有”时,have与there be的选用
注意动词词组分类(见),尤其要注意各类动词词组的使用特点及有的动词词组的主被动转换使用。
Make use of sth→sth is made use of(介词不要掉了)/use is made of sth.
10.Hope, intend, expect, plan, want, think, mean等动词用过去完成时表示没有实现的愿望,计划,打算等。

答案B. This is the first time 后面所加从句应为现在完成时,故选B。
(2) ---Have you ____ been to our town before? ---No, it's the first time I ___ here.
A. even, come B. even, have come C. ever, come D. ever, have come
答案D. ever意为曾经或无论何时,反意词为never,此两词常用于完成时。
注意:非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。
(错)I have received his letter for a month.
(对)I haven't received his letter for almost a month.
11.12 比较since和for
Since 用来说明动作起始时间,for用来说明动作延续时间长度。例如:
I have lived here for more than twenty years.我住在这儿二十多年了。
I have lived here since I was born. 我从出生起就住在这儿了。
注意:并非有for 作为时间状语的句子都用现在完成时。
I worked here for more than twenty years. (我现在已不在这里工作。)
I have worked here for many years.(现在我仍在这里工作。)
注意:用句型转换的方法,很容易排除非延续动词在有for/since结构的完成时中的误用。
1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
显然,第二句不对,它应改为 Harry got married six years ago. 或 Harry has been married for six years.
11.13 since的四种用法
1) since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past
six)。例如:
I have been here since 1989. 1989起,我一直在这儿。
2) since +一段时间+ ago。例如:
I have been here since five months ago. 我在这儿,已经有五个月了。
3) since +从句。例如:
Great changes have taken place since you left. 你走后,变化可大了。
Great changes have taken place since we were here. 我们走后,变化可大了。
4) It is +一段时间+ since从句。例如:
It is two years since I became a postgraduate student. 我考上研究生有两年了。
11.14 延续动词与瞬间动词
1) 用于完成时的区别
延续动词表示经验、经历; 瞬间动词表示行为的结果,不能与表示段的时间状语连用。例如:
He has completed the work. 他已完成了那项工作。 (表结果)
I've known him since then. 我从那时起就认识他了。(表经历)
2) 用于till / until从句的差异
延续动词用于肯定句,表示"做……直到……" 瞬间动词用于否定句,表示"到……,才……"。例如:
He didn't come back until ten o'clock. 他到10 点才回来。
He slept until ten o'clock. 他一直睡到10点。
典型例题
1. You don't need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B. 首先本题后句强调对现在的影响,我知道她的模样,你不用描述。再次,several
times告知为反复发生的动作,因此用现在完成时。
2. ---I'm sorry to keep you waiting.
---Oh, not at all. I ___here only a few minutes.
A. have been B. had been C. was D. will be
答案A. 等待的动作由过去开始,持续到现在,应用现在完成时。
11.15 过去完成时
1) 概念:表示过去的过去
----|----------|--------|----> 其构成是had +过去分词构成。 那时以前 那时 现在
2) 用法
a. 在told, said, knew, heard, thought等动词后的宾语从句。例如:
She said (that)she had never been to Paris. 她告诉我她曾去过巴黎。
b. 状语从句
在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。例如:
When the police arrived, the thieves had run away. 警察到达时,小偷们早就跑了。
c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"。例如:
We had hoped that you would come, but you didn't. 那时我们希望你能来,但是你没有来。
3) 过去完成时的时间状语before, by, until , when, after, once, as soon
as。例如:
He said that he had learned some English before. 他说过他以前学过一些英语。
By the time he was twelve, Edison had began to make a living by himself. 到了十二岁那年,爱迪生开始自己谋生。
Tom was disappointed that most of the guests had left when he arrived at the party.
汤姆失望了,因为他到达晚会时,大部分客人已经走了。
典型例题
The students ___ busily when Miss Brown went to get a book she ___ in the office.
A. had written, left B,were writing, has left C. had written, had left D. were writing, had left
答案D.
"把书忘在办公室"发生在"去取书"这一过去的动作之前,因此"忘了书"这一动作发生在过去的过去,用过去完成时。句中when表示的是时间的一点,表示在"同学们正忙于……"这一背景下,when所引导的动作发生。因此前一句应用过去进行时。
注意: had hardly… when 还没等…… 就……。例如:
I had hardly opened the door when I he hit me. 我刚打开门,他就打了我。
had no sooner…than 刚…… 就……。例如:
He had no sooner bought the car than he sold it. 他刚买了这辆车,转眼又卖了。
11.16 用一般过去时代替过去完成时
1) 两个动作如按顺序发生,又不强调先后,或用then,and,,but 等连词时,多用一般过去时。例如:
When she saw the mouse,she screamed. 她看到老鼠,就叫了起来。
My aunt gave me a hat and I lost it. 姑妈给了我一顶帽子,我把它丢了。
2 ) 两个动作相继发生,可用一般过去时;如第一个动作需要若干时间完成,用过去完成时。例如:
When I heard the news, I was very excited.
3) 叙述历史事实,可不用过去完成时,而只用一般过去时。例如:
Our teacher told us that Columbus discovered America in 1492.
11.17 将来完成时
1) 构成will have done
2) 概念
a. 状态完成:表示某事继续到将来某一时为止一直有的状态。例如:
They will have been married for 20 years by then. 到那时他们结婚将有二十年了。
b. 动作完成:表示将来某一时或另一个将来的动作之前,已经完成的动作或获得的经验。例如:
You will have reached Shanghai by this time tomorrow. 明天此时,你已经到达上海了。
11.18 现在进行时
现在进行时的基本用法:
a. 表示现在(指说话人说话时)正在发生的事情。例如: We are waiting for you. 我们正在等你。
b. 习惯进行:表示长期的或重复性的'动作,说话时动作未必正在进行。例如:
Mr. Green is writing another novel. 他在写另一部小说。(说话时并未在写,只处于写作的状态。)
c. 表示渐变,这样的动词有:get, grow, become, turn, run, go, begin等。例如:
The leaves are turning red. 叶子在变红。
It's getting warmer and warmer. 天越来越热了。
d. 与always, constantly, forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。例如:
You are always changing your mind. 你老是改变主意。
典型例题
My dictionary ___, I have looked for it everywhere but still___ it.
A. has lost, don't find B. is missing, don't find C. has lost, haven't found D. is missing, haven't found.
答案D. 前句是一个仍在持续的状态,应用进行时,由于没有找到,学英语的好网站,其影响仍然存在,应用完成时,瞬间动词用于否定式时可用于完成时。
11.19 不用进行时的动词
1)表示事实状态的动词,如have, belong, possess, cost, owe, exist, include,
contain, matter, weigh, measure, continue等。例如:I have two brothers. 我有两兄弟。
This house belongs to my sister. 这房子是我姐的。
2)表示心理状态的动词,如know, realize, think see, believe, suppose, imagine, agree, recognize, remember, want, need, forget, prefer, mean, understand, love, hate等。例如:I need your help. 我需要你的帮助。
He loves her very much. 他爱她很深。
3)瞬间动词,如accept, receive, complete, finish, give, allow, decide, refuse等。例如:
I accept your advice. 我接受你的劝告。
4)系动词,如seem, remain, lie, see, hear, smell, feel, taste, get, become, turn等。例如:
You seem a little tired. 你看上去有点累。
11.20 过去进行时
1)概念:表示过去某时正在进行的状态或动作。
2)过去进行时的主要用法是描述一件事发生的背景;一个长动作延续的时候,另一个短动作发生。
3) 常用的时间状语有this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while等。例如:
My brother fell while he was riding his bicycle and hurt himself. 我兄弟骑车时摔了下来,受了伤。
It was raining when they left the station. 他们离开车站时,正下着雨。
When I got to the top of the mountain, the sun was shining. 我到达山顶时,阳光灿烂。
典型例题
1) Mary ___ a dress when she cut her finger.
A. made B. is making C. was making D. makes
答案C.
割伤手指是已发生的事情,学英语的好网站,应用过去时。同时,when表时间的同时性,"玛丽在做衣服时"提供事情发生的背景,因此用过去进行时。
2) As she ___ the newspaper, Granny ___ asleep.
A. read;was falling B. was reading; fell C. was reading; was falling D. read;fell
答案B.句中的as = when, while,意为"当……之时"。描述一件事发生的背景时,用过去进行;一个长动作发生的时候,另一个短动作发生。句意为 "在她看报纸时,奶奶睡着了。"句中的 fell(fall的过去时),是系动词,后跟形容词,如:fall sick。
英语语法经典例题800例:非谓语动词(例题1)
【导语】英语语法让很多学生都头疼,因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全,希望对同学们的英语语法学习有所帮助。更多内容尽在。
1. Everyone in our class was working hard and doing what we could _______ a good college.
A. enter B. to enter
C. entering D. entered
【陷阱】容易误选A。有的同学一看到空格前的情态动词 could 就断定此处应填动词原形 enter。
【分析】其实正确答案应是B。此句为省略句,即在 could 后省略了动词 do,若把句子补完整应为Everyone in our class was working hard and doing what we could do to enter a good college。即句中的不定式短语(to enter a good college)是用作目的状语的,而不是与情态动词(could)一起构成谓语。请再看类似例句:
(1) They did what they could to comfort her. 他们尽量安慰她。
(2) They did everything they could to save her life. 他们尽一切力量拯救她的性命。
(3) He studies as hard as he could to catch up with his classmates. 他拼命学习以便赶上他的同学。
值得指出的是,这也并不是说今后只要遇到类似结构的题就一定选带to不定式。请看以下试题:
(4) He ran as fast as he could _____ to catch the early bus.
A. to hope B. hope
C. hoping D. hoped
此题的答案是 C不是A,其中的现在分词短语 hoping to catch the early bus 用作伴随状语。
(5) He spent every minute he could _____ spoken English.
A. practise B. to practise
C. practising D. practised
此题答案选 C,这与前面动词 spent 的搭配有关,即 spend … (in) doing sth。若将此句补充完整,即为 He spent every minute he could spend in practising spoken English.
(6) Before going abroad he devoted all he could ____D____ his oral English.
A. improve B. to improve
C. improving D. to improving
此题答案选D,注意两点:一是 devote … to … 是固定搭配,意为“把……贡献给……”;二是其中的 to 是介词,不是不定式符号,后接动词时要用动名词。
2. He knows nothing about it, so he can’t help _______ any of your work.
A. doing B. to do
C. being doing D. to be done
【陷阱】容易误选B,根据 can’t help doing sth 这一结构推出。
【分析】其实答案应选A。比较以下结构:
can’t help to do sth = 不能帮助做某事
can’t help doing sth = 禁不住做某事,情不自禁地做某事
又如下面一题,答案也是 B:
She can’t help ____ the house because she’s busy making a cake.
A cleaning B. to clean
C. cleaned D. being cleaned
再请看以下试题:
While shopping, people sometimes can’t help _____ into buying something they don’t really need.
A. to persuade B. persuading
C. being persuaded D. be persuaded
此题应选C,句中的 can’t help 意为“禁不住”(注意根据句意用被动形式)。
3. All her time _______ experiments, she has no time for films.
A. devoted to do B. devoted to doing
C. devoting to doing D. is devoted to doing
【陷阱】几个干扰项均有可能误选。
【分析】此题最佳答案为B。现分析如下:
(1) devote 意为“致力于,献身于”,主要用 devote…to…或be devoted to,其中的to 是介词,不是不定式符号,故后接动词时要用动名词,不用不定式。
(2) 选A错误:若将 do 改为 doing 则可以。
(3) 选B正确:all her time devoted to doing experiments为独立主格结构,用作状语。
(4) 选C错误:因为all her time 与 devote 为被动关系,故应将devoting改为devoted。
(5) 选D错误:若单独看 All her time is devoted to doing experiments,此句并没有错,但问题是逗号前后两个简单句没有必要的连接方式,所以从整体上看仍不对,假若在后一句的句首加上and或so,则可选D,或将D将中的is 改为 being也可选它。
英语语法经典例题800例:虚拟语气(例题)
【导语】英语语法让很多学生都头疼,因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全,希望对同学们的英语语法学习有所帮助。更多内容尽在。
1. I forget where I read the article, or I _____ it to you now.
A. will show B. would show
C. am going to show D. am showing
【陷阱】几个干扰项均有可能误选。
【分析】正确答案选B。根据上文的语境可知句中的 or 隐含有一个虚拟的条件,即 or=if I didn’t forget where I read the article(要是我没忘记我在哪儿读过这篇文章的话——但事实上忘了)。
2. “It looks as if he were drunk.” “So it does. _____.”
A. He’d better give up drinking
B. He shouldn’t have drunk so much
C. Health is more important than drink
D. I wonder why he is always doing so
【陷阱】几个干扰项均有可能误选,主要是受句中 drunk 一词的影响。
【分析】最佳答案为D。关键信息是It looks as if he were drunk 中的虚拟语气,句子既然用了虚拟语气,也就是说,“他喝醉了”不是事实,只是他的言行好像是醉了,所以此题的最佳答案是D。
3. “Mary looks hot and dry” “So _____ you if you had so high a fever.”
A. do B. are
C. will D. would
【陷阱】容易误选A或C。选A者,认为前后两句的动词性质应一致;选C者,认为其后带有if 条件状语从句,从语气上看,主句应用将来时态。
【分析】此题最佳答案为D。分析如下:
(1) “so + 助动词 + 主语”是一个很有用的结构,它表示“……也一样”时。如:
He likes to watch TV, and so do I. 他喜欢看电视,我也一样。
When animals and plants disappear, so will man. 当动植物消失的时候,人类也会随之消失。
(2) 由于空格后的 if 条件状语从句的谓语用的是虚拟语气(这是很重要的信息),所以主句要用 would 而不用 will,即答案应选D。
英语语法经典例题800例:强调句(例题)
【导语】英语语法让很多学生都头疼,因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全,希望对同学们的英语语法学习有所帮助。更多内容尽在。
1. ____ that caused him to serve dinner an hour later than usual.
A. It was we being late B. It was our being late
C. It was we were too late D. It was because we were late
【陷阱】此题容易误选D,认为强调的是原因状语从句 because we were late。
【分析】但实际上,此题的答案为B,强调的是句子主语 our being late,此题若还原成非强调句,即为:
Our being late caused him to serve dinner an hour later than usual.
注意,强调句的一个显著特点是,若去掉强调结构 it is [was]… that…,句子仍然成立;换句话说,该结构中的 that 不能充当句子成分。
2. “How was ______ they discovered the entrance to the underground palace?” “Totally by chance.”
A. it that B. he that
C. it when D. he which
【陷阱】几个干扰项均可能误选。
【分析】答案选A,为强调句的特殊疑问句形式,其相应的陈述句形式为:
It was totally by chance that they discovered the entrance to the underground palace.
比较以下各题,它们也属强调句的特殊疑问句形式:
(1) Who was it _____ saved the drowning girl?
A. since B. as C. that D. he
答案选C,被强调成分为 who,该句实为类似 It was Tom that saved the drowning girl. 这类强调句的特殊疑问句形式(即对其中的Tom 提问而得)。
(2) What is it _____ his daughter needs most?
A. what B. which C. that D. if
答案选C,被强调成分为 what,该句实为类似 It is a bike that his daughter needs most. 这类强调句的特殊疑问句形式(即对其中的a bike 提问而得)。
3. _____ was very ______ that little Jim wrote the letter.
A. It, careful B. It, carefully
C. He, careful D. He, carefully
【陷阱】几个干扰项均有可能误选,但最有可能误选的可能是A,认为这是一个普通的系表结构,即认为第二空要填形容词作表语。
【分析】其实,此题是一个强调句,其非强调形式为 Little Jim wrote the letter very carefully. 若用 it is … that… 的强调句式强调其中的状语 very carefully 即为上面一题的题干,所以答案应选B。请看下面几例,也属强调结构:
(1) It was when she was about to go to bed ______ the telephone rang.
A. since B. as C. that D. then
答案选C,被强调成分为 when she was about to go to bed 这一时间状语从句。
(2) It may have been at Christmas _____ John gave Mary a handbag.
A. before B. who C. that D. when
答案选C,被强调成分为 at Christmas,其中的动词 be 采用了 may have been 这一较为复杂的形式。
4. “Where did you find the professor who made the speech yesterday?” “It was in the hall ______ the students
often have a meeting.”
A. where B. which
C. that D. when
【陷阱】很可能误选C,认为这是一个强调句,强调地点状语 in the hall。
【分析】假若选C,即有 It was in the hall that the students often have a meeting,该句的意思是“学生们通常是在
大厅开会”,单独看这一句,无论是其意思还是其语法均未错,但若将其与上文联系起来看,则不通,因为上文的意思是“你是在
哪儿找到昨天作报告的那位教授的?”假若将答句改为 It was in the hall that I found the professor,则完全可以。
其实,此题的最佳答案是A,where the students often have a meeting 为定语从句,用以修饰其前的名词 the hall,句意
为“是在学生们经常开会的那个大厅(找到教授的)”,这样语意就通顺了。
5. It was what he meant rather than what he said ______ annoyed me.
A. which B. as
C. what D. that
【陷阱】几个干扰项均有可能误选。
【分析】此题为一个强调句型,空格处应填 that (即选D),被强调成分为 what he meant rather than what he said。句意
为“让我生气的不是他说的话,而是他话中的意思”。请再看两例:
(1) It was his nervousness in the interview ______ probably lost him the job.
A. which B. since C. that D. what
答案选C,为强调句型,被强调成分为 his nervousness in the interview,句意为“很可能是面试时表现出紧张,使他失去
了这份工作”。
(2) It is the ability to do the job ______ matters not where you come from or what you are.
A. one B. that C. what D. it
答案选B,为强调句型,被强调成分为 the ability to do the job,句意为“重要的是你做工作的能力,而不是你来自何地
或你是从事什么工作的”。

◆典型陷阱题分析◆
1. She was so angry and spoke so fast that none of us understood _______ he said meant.
A. that B. what
C. that that D. what what
【陷阱】可能误选B。许多同学一看选项首先就排除了C和D,认为这样两个“引导词”叠用的情况不太可能。在A和B两个选项中,选项A肯定不行,因为它引导宾语从句时不能充当句子成分,所以便选择了B。
【分析】正确答案选 D。第一个what 用作动词 meant 的宾语,第二个what 用作动词 said 的宾语,即在 none of us understood what what he said meant 中,none of us understood 为主句,what what he said meant 为宾语从句,而在此宾语从句中又包括有 what he said 这样一个主语从句。
2. After _______ had happened he could not continue to work there.
A. which B. how
C. what D. having
【陷阱】可能误选A。
【分析】最佳答案选 C。有的同学误选A,是因为认为介词后应接关系代词 which,但实际上,若填关系代词,其前没有先行词,这根据不是一个定语从句。另外,由于 had happened 缺主语,所以B和D也不能选。请再做下面一题(答案选B):
He pointed to ______ looked like a tomb and said, “Ghost.”
A. that B. what
C. which D. as
3.“Is ______ you want to say?” asked the teacher.
A. this B. that
C. all that D. that all
【陷阱】根据中文字面意思误选A或B。
【分析】最佳答案选 D。假若选A或B,那么转换成陈述句即为:This is you want to say. / That is you want to say. 显然句中的两个谓语动词 is与want相冲突。选D组成的句子是 Is that all you want to say? 其中的that 为句子主语,all 为表语,you want to say 为定语从句,用以修饰all。
4. “When ______ leave for Japan?” “When ______ leave for Japan is kept secret.”
A. they will, will they B. will they, they will
C. they will, they will D. will they, will they
【陷阱】可能误选D,认为 when 后应用疑问句词序。
【分析】最佳答案选 B。第一个when引出的是一个特殊疑问句,故用疑问词序;第二个 when 引出的是主语从句,故其后用陈述句词序。请做以下试题(答案选C):
(1) None knows if _______ that boy, but if _______ him, her parents will be disappointed.
A. she will marry, she will marry B. she marries, she marries
C. she will marry, she marries D. she marries, she will marry
(2) “Where _______ go to work?” “Where _______ go to work is not known.”
A. we shall, we shall B. shall we, shall we
C. shall we, we shall D. we shall, shall we
5. Someone is ringing the doorbell. Go and see ______.
A. who is he B. who he is
C. who is it D. who it is
【陷阱】几个干扰项均有可能误选。
【分析】此题最佳答案为D。首先可以排除A和C,因为空格处实为一个宾语从句,所以不能用疑问句词序。另一方面,但按英语习惯,当用于指代身份不明的人时,要用代词it,而不用 he 或she等。比较以下两句:
Mr Smith is at the door. He wants to see you. 史密斯先生在门口,他想见你。
Someone is at the door. It may be the postman. 有个人在门口,可能是邮递员。
第一句因前面指明了是 Mr Smith,所以后面用代词 he;而第二句因前面用的是不定代词 someone,说明此人身份尚不明确,故其后用了代词 it 来指代。
6. Don’t you know, my dear friend, ______ it is your money not you that she loves?
A. who B. which
C. that D. what
【陷阱】此题容易误选 A或B:选 A 的同学认为这是指人的,故用who;选B的同学认为这是非限制性定语从句,两者都是误认为这是定语从句(注意没有先行词)。
【分析】其实答案应选C。that引导的是一个宾语从句,用作动词 know 的宾语,它只是被句中的插入语 my dear friend 隔开罢了。请做以下试题(答案均为C):
(1) Everyone knows, perhaps except you, _______ your girl-friend is a cheat.
A. who B. which
C. that D. what
(2) I think, though I could be mistaken, ______ she liked me.
A. who B. which
C. that D. what
(3) He told me the news, believe it or not, ______ he had earned $1 000 in a single day.
A. that B. which
C. as D. because
前面两题 that 引导宾语从句,后面一题 that同位语从句(修饰the news)。
英语语法大全:特殊同位语归纳
英语语法让很多学生都头疼,因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全,本章主要介绍英语语法中的句子成分,希望对同学们的英语语法学习有所帮助。更多内容尽在。
特殊同位语归纳
当两个词或词组在一个句子中具有相同的语法地位而且描述相同的人或事物时,我们称它们为同位语。基本形式的同位语大家一般不会出错,但有几种同位语,或由于本身结构特殊,或由于它修饰的成分结构比较特殊,往往会引起误解。现小结并举例说明如下,希望引起同学们的注意。
1. 代词we, us, you等后接同位语
Are you two reading? 你们二人在看书吗?
They three joined the school team. 他们3人参加了校队。
She has great concern for us students. 她对我们学生很关心。
He asked you boys to be quiet. 他要你们男孩子安静些。
We girls often go to the movies together. 我们女孩子经常一起去看电影。
2. 不定式用作同位语
Soon came the order to start the general attack. 很快下达了发起总攻的命令。(to start the general attack与the order同位)
He followed the instruction to walk along a certain street where I picked him up. 他照吩咐沿某一条街走,我在那里接他上了车。(to walk along…与the instruction同位)
3. -ing分词用作同位语
He's getting a job tonight driving a truck. 他今晚得到一个开卡车的差事。(driving a track与a job同位)
She got a place in a laundry ironing shirts. 她在一家洗衣店得到一个熨衣服的职位。(ironing shirts与a place同位)
The first plan, attacking at night, was turned down. 第一个计划是夜袭,被拒绝了。(attacking at night与the first plan同位)
4. 形容词用作同位语
The current affair, the biggest in its history, is being held in Guangzhou. 目前的交易会,是有史以来规模最大的,正在广州举行。
He read all kinds of books, ancient and modern, Chinese and foreign. 他读了很多书,古今中外都有。
People, old and young, took to the streets to watch the parade. 老老少少的人都来到街头观看游行。
【注】这类同位语与定语比较接近,可转换成定语从句。如:
The current affair, the biggest in its history, is being held in Guangzhou.
=The current affair, which is the biggest in its history, is being held in Guangzhou.
5. none of us之类的结构用作同位语
We none of us said anything. 我们谁也没说话。
We have none of us large appetites. 我们谁饭量都不大。
They neither of them wanted to go. 他们两人都不想去。
They've neither of them succeeded in winning her confidence. 他们两人谁也没能赢得她的信任。
【注】同位语并不影响其后句子谓语的“数”,如:
学生每人都有一本词典。
正:The students each have a dictionary.
误:The students each has a dictionary.
请比较下面一句(谓语用了单数,因为each为句子主语):
正:Each of the students has a dictionary.
6. 从句用作同位语(即同位语从句)
They were worried over the fact that you were sick. 他们为你生病发愁。
I received a message that she would be late. 我得到的信息说她可能晚到。
The news that we are having a holiday tomorrow is not true. 明天放假的消息不实。
The idea that you can do this work without thinking is wrong. 你可以不动脑筋做此工作的想法是错误的。

名词:
1、英语名词可分专有名词和普通名词两大类:
1、专有名词是个别的人、地、物、团体、机构等的专用名称。
专有名词如果是含有普通名词的短语,则必须使用定冠词the。如:the Great Wall(长城)
姓氏名如果采用复数形式,则表示该姓氏一家人(复数含义),如:the Greens( 格林一家人)。
2、普通名词又分为可数名词和不可数名词。
2、英语可数名词的单复数:英语可数名词有单数和复数两种形式。
1hero→heroes, photo→photos, piano→pianos.
不可数名词一般没有复数形式,说明其数量时,要用有关计量名词。一盒牛奶:
3、名词所有格:
1、 名词所有格如:Childern’s Day(儿童节), my sister’s book(我姐姐的书)
(2)以s或es结尾的复数名词。只在词尾加’。如:Teachers’ Day(教师节)

4、名词或代词作主语时和谓语之间的单复数的一致问题:
1、谓语和谓语基本保持单复数的一致,即:主语是可数名词单数或不可数名词时,谓语动词用单数形式:如:The computer was a great invention.(计算机是个了不起的发明)The water in the glass is very cold.(玻璃杯里的水很冷)
2、集体名词(如family, class, team, group, row, police, school等)做句子主语时,
① 如果表示整体概念,则谓语用单数形式,如:Class Three is a very good class.(三班是好班)
② 如果表示其中的所有成员时,则谓语用复数形式,如:Class Three have a map of China.(三
班有张中国地图)
3、Chinese, Japanese, fish, sheep, people等表示单个时谓语用单数,表示许多时,谓语用复数。如:There is a sheep in the yard.(院子里有只绵羊) / There are some sheep in the yard.(院子里有一些绵羊)
4、maths, news等虽然有s结尾,但不是复数,因此谓语仍用单数:The news is very exciting. (这个消息令人兴奋)

7、and 连接两个名词做主语时,谓语原则上用复数,但是两个名词若构成一个整体事物时,谓语则用单数。如:The teacher and his son are picking apples now.(老师和他的儿子在摘苹果) / Fish and chips is very famous food. (鱼和薯条是一种出名的食品)
8、 there be 句型中be的单复数一般由靠近的名词决定。如:There is a table and four chairs in the room.(房间里有一张桌子和四张椅子)
9、用both…and…连接两个事物做主语时,谓语一般用复数。如:Both you and I are required to be here tomorrow.(你和我明天要求都来)
10、主语中含有with的短语时,谓语单复数由with之前的人物决定。如:A woman with a 7-year-old child was standing at the side of the road. (一名妇女带着一个七岁的孩子(当时)就站在路边)
11、either…or…或者 neither…nor…连接两个人物做句子主语时,谓语采用就近原则。如:Either you or he is right.(要么是你对,要么是他对。/你和他有一个人是对的) / Neither you nor I am going there.(你和我都不打算去那里)

但是,population一词又有特殊情况: What’s the population of China?(中国人口是多少?)(句子用单数) / Three quarters of the population in this city are Arabs(阿拉伯人).(这个城市四分之三的人口是阿拉伯人)(句子用复数)
5、部分名词用法辨析:
1、sport、game、match、race 的区别:sport通常指“户外运动”,以锻炼为主,概念较大;game意思是“运动、比赛”,不管户内户外还是脑力体力,指以胜负为主的运动;match意为“竞赛、比赛”,多指正式比赛;race主要表示“赛跑、赛马、赛车”。如:People all around the world enjoy sports.(全世界的人都喜爱运动) / The 2008 Olympic Games will be held in Beijing.(2008奥运会将在北京举行)(被动句) / Our school football team won the league match(联赛).(我们学校足球队取得了联赛冠军) / They were strong and won the boat race.(汤他们很棒,赢得了划艇比赛)

在句中相当于时间状语的从句叫时间状语从句。时间状语从句常由从属连词when,while,as,before,after,as soon as,since,till,until等引导。如:
What are you going to be when you grow up ?你长大以后打算干什么?
I will phone you as soon as I get there .我一到那儿就给你打电话。
1.引导时间状语从句的从属连词及用法
(1)when,while,as引导时间状语从句意为“当……时”。如:
When the clock struck twelve ,all the lights went out.当时钟敲了十二下,灯全部都熄了。
While Peter was reading ,his wife was cooking.彼得看书的时候,他妻子在做饭。
He dropped the glass as he stood up .他站起来时,把杯子摔碎了。
注意:
①when表示“当……时”,多用来表示时间点,也可表示时间段;从句中既可以用非延续性动词,也可用延续性动词;when 从句多用一般过去时,主句时态没有限制,根据具体情况而定;在将来时态中,常用when引导从句,且从句须用一般现在时代替将来时;when表示时间段时可与while通用,但从句中必须用延续性动词。如:
I was just reading a book when she came into my room.她走进我房间时,我正在看书。
When I got to the airport,the guests had left.当我赶到飞机场时,客人们已经离开了。
When the manager comes here for a visit next week,I'll talk with him about this.下周经理来这参观时,我会和他谈谈此事。
②while表示“当……的时候;在……之时;在……期间”,所引导的时间状语从句的谓语动词必须是延续性动词或表示状态的动词,且通常用进行时。如:
While my wife was reading the newspaper,I was watching TV.当妻子在看报纸的时候,我在看电视。
You can't do your homework while you're watching TV.你不能一边看电视一边做家庭作业。
③as引导时间状语从句时,从句的谓语动词既可以是延续性的,也可以是非延续性的。当从句中的谓语动词是延续性动词,表示“当……的时候”时,往往可以与when或while通用,但as更侧重主句与从句的行为同时发生,常译作“随着……;一边……,一边……”。如:
Kate read the book as she went along.凯特边走边读书。
We took notes as we listened to the lecture.我们边听课边记笔记。
(2)before引导时间状语从句意为“在……之前”。如:
Don't jump off the train before it stops.火车停之前不要往下跳。
Look at both ways before you cross the road.过马路之前左右两边都要看。
I didn't know any English before I came here。我来这儿之前,一点英语都不懂。
(3)after引导时间状语从句意为“在……之后”。如:

注意:
为了表明动作的先后,从句中动词可用过去完成时,主句用一般过去时。如:

(4)until,till引导时间状语从句意为“直到……为止”。如:
They waited till/until I returned.他们一直等到我回来。
Mr.Wang kept on explaining until the student understood.王先生反复地解释直到学生听懂了为止。
注意:
①until在肯定句中只与延续性动词连用,在否定句中通常与非延续性动词连用,表示相应动作开始的时间,意为“直到……才”。如:
He didn't leave until I came back.直到我回来他才离开。
②till用作连词,与until同义,两者经常可换用,只是 until 比 till 稍正式。在正式文体中,一般用 until,而在口语或非正式文体中则两者都可。till多与名词或较短的从句连用,而较长较复杂的成分多用 until;在句子开头时,用 until而不用till。如:
She lived in Tokyo till (until)she died.她一直住在东京直到去世。
(√)Until he comes back,nothing can be done.在他回来之前,什么也不能做。
(×)Till he comes back,nothing can be done.在他回来之前,什么也不能做。

否定回答needn’t换,需要need, dare敢。
should应该,would愿,have to被迫表客观。
情态动词虽然数量有限,但用法广泛。清楚所有情态动词的表示意义,对英语遣词造句具有非常重要的作用。
