　　初中英语语法总结1

构词法：

英语构词法主要有：合成法、派生法和转换法。

1、合成法：如：spaceship, headache, basketball, playground等等。

2、派生法：(1)派生名词：①动词+er/or ②动词+ing ③动词+(t)ion ④形容词+ness ⑤其他,如：inventor, learner, swimming, congratulation, kindness, carelessness, knowledge

(2)派生形容词：①名词+y ②名词+ful ③动词+ing/ed ④friendly ⑤dangerous ⑥Chinese; Japanese ⑦English ⑧French ⑨German ⑩国名+(i)an 如：snowy, sunny, hopeful, beautiful, interesting, following, daily(每日的),nervous, delicious

(3)派生副词：①形容词+ly ②其它,如：slowly, angrily, full→fully, good→well, possible→possibly

3、转换法：

(1)形容词→动词,如：dry(干燥的)→dry(弄干), clean(干净的)→clean(打扫,弄干净),等等。

(2)动词→名词,如：look, walk, rest, work, study, swim, go, talk等等。

(3)名词→动词,如：hand(手)→(传递),face(脸)→(面对)等等。

(4)形容词→副词,如：early→early, fast→fast等等。

(5)副词→连词,如：when(什么时候)→(当……时候),等等。

(6)介词→副词,如：in(到……里)→(在里面;在家),on(在…上)→(进行,继续)

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)

(3)有些表示时间、距离以及世界、国家、城镇等无生命的名词,也可在词尾加’s. 如：

today’s newspaper(今天的报纸), ten minutes’ break(十分钟的课间休息),

(4)无论表示有生命还是无生命的东西的名词,一般均可用介词of短语来表示所有关系。如：

2、[注解]：

① ‘s还可以表示某人的家或者某个店铺,如：my aunt’s(我阿姨家), the doctor’s(诊所)

② 两人共有某物时,可以采用 A and B’s 的形式,如：Lucy and Lily’s bedroom(露西和丽丽合住的卧室)

③ “of+名词所有格/名词性物主代词”,称为双重所有格,如：a friend of my father’s(我父亲的一位朋友), a friend of mine(我的一位朋友)

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)

5、glasses, shoes, socks, trousers, gloves等名词往往用复数形式,故谓语用复数。如：

The trousers are very cheap and I want to take them.(裤子很便宜,我想买)

6、a lot of 后跟名词复数时谓语用复数形式,跟不可数名词时谓语用单数形式。如：A lot of students are playing baseball now.(现在有许多学生在打垒球) A lot of time was wasted on that work.(大量的时间花在了那个工作上)(被动句)

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)

12、表示一段时间或长度概念的复数名词做主语时,谓语一般用单数。如：Two months is not a short time.(两个月不是个短时间)Two thousand kilometers is quite a long distance(距离).(两千千米是相当长的一段距离)

13、主语中含有half of… / (three quarters)of… / all (of) the ….等词语时,谓语的单复数由名词确定,如：Over three quarters of the information on the Internet is in English. / A third of the students were playing near the lake.(学生的三分之一(当时)正在湖边玩耍) / All of the water in these rivers has been polluted.(这些河流中的水已经被污染了)(被动句)

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)

2、festival、holiday、vacation的区别：festival“节日”,指喜庆的日子或持续一段时间的文娱活动;holiday(假日、休息日),指法定假日或风俗习惯,复数可以表示一个较长的假期;vacation“假期”,指学习或工作中一段长时间的休息。如：The Shanghai Television Festival will be held next month.(上海电视节将在下个月举行) / Sunday is a holiday and most people do not work.(星期天是个假日,多数人不工作) / What are you going to do during the summer vacation/holidays?(在暑期你打算做什么事情?)

3、journey、tour、trip、travel的区别：journey指在陆地上(或海上或空中)进行的长途旅行,不知终点,含有辛苦的意思;tour指途中作短期逗留的巡回旅行,强调游览多处,常用来指观光等;trip通常指往返定时的短途旅行,如出差度假等;travel多指长期或长途的观光旅行,尤其指到国外,没有明确目的地,也作不可数名词,指旅行这一行为。如：He made up his mind to make the journey to Dunhuang.(他拿定主意要去敦煌旅行)/ He has gone on a walking tour.(他步行观光去了) / He took several trips to Shanghai last yeaar.(去年他去了上海好几次) / Did you go to Santiago(圣地亚哥) during your travels?(旅行期间你去圣地亚哥了吗?) / Travelling through thick forests is dangerous.(在密林里边穿行是很危险的)

4、sound、noise、voice的区别：sound指各种声音;noise主要指“噪音”;voice指人的“嗓音”。如：The noise of the street kept me awake in the night.(街上的喧嚣声让我彻夜难眠) / All of a sudden there was the sound of shots and a cry.(突然间传来几声枪响和一声尖叫) / The singer has lost her ringing voice as a result of a bad cold.(因为感冒的缘故,这个歌唱家失去了她银铃般的嗓音)

5、fish的问题：指许多条鱼且不管种类时,用fish,单复数相同;fishes 指许多种类的鱼;fish指“鱼肉”时是不可数名词。如：There are many kinds of fishes in the pool. (池子里有很多种类的鱼)/ I prefer fish to meat.(与肉相比我更喜欢鱼)

代词：

1、代词的分类：英语中代词分为：人称代词、物主代词、反身代词、指示代词、关系代词、疑问代词、连接代词和不定代词等等。

2、人称代词：人称代词代替人和事物的名称,分为主格和宾格两种形式。

四：时态一致

时态一致是英语四、六级考试的一个重要内容。通常应由主句谓语的时态决定从句的谓语时态。一般原则是：

1、当主句谓语使用现在时或将来时，从句的谓语根据具体情况使用任何时态

He says that he lives in Wuhan.

We hope that there will be many people at your party today.

“Did you hear that Bill finally sold the house?” “Yes, but I don’t know who bought it.”

“There’s a lot of excitement on the street.”

“There certainly is. Do you suppose the astronauts have returned?”

2、当主句谓语使用过去时的时候，从句的谓语必须使用过去范围的时态

He said he was writing a novel.

The teacher wanted to know when we would finish the experiment.

He said his father had been an engineer.

3、当从句是表示没有时间概念的真理时，从句的谓语应使用一般现在时。例如：

The teacher told them since light travels faster than sound, lightning appears to go before thunder.

注：在此种情况下，即使主句谓语用了过去式的各种时态，从句谓语也应用一般现在时。

4、从句谓语只能用虚拟语气的情况

利用时态一致原则确定从句动词时态时，还应注意，若主语动词是表示命令、请求、要求、建议、劝告等的动词，从句谓语只能用虚拟语气，不能遵循时态一致原则。例如：

We insisted that we do it ourselves.

五、动词的语态

语态也是动词的一种形式，英语有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态表示主语是动作的承受者。

1)We use electricity to run machines. (主动语态)

2)Electricity is used to run machines. (被动语态)

1.不能用于被动语态的动词和短语

(1)在英语中，不及物动词不能用于被动语态，但有些不及物动词(包括短语)容易引起误用。如：appear, belong, belong, die, escape, fall, happen, last, remain, succeed, occur, come true, take place, consist of。

(2)某些表示状态或特征的及物动词，如：become, contain, cost, fit, have, resemble, suit也没有被动语态。

2.被动语态的时态形式

常用的被动语态有表1所列的几种时态形式。

SPAN> 一般时 进行时 完成时

现在 am asked am being asked

is asked is being asked

are asked are being asked

过去

was be asked was being asked

were be asked were being asked

将来 shall be asked shall have been asked

will be asked will have been asked

过去 should be asked should have been asked

将来 would be asked would have been asked

3.短语动词的被动语态

短语动词转换为被动语态时，通常被看作是一个动词，后面的介词或副词不能拆开或省略。例如：

1)So far no correct conclusion has arrived at.

2)All the rubbish should be got rid of.

4.“get + -ed分词”的被动语态

“get + -ed分词”结构强调动作的结果，而非动作本身，常用来表示突发性的，出乎意料的偶然事件。例如：

The boy got hurt on his way home from work.

另外，“get + -ed分词”还可用于谈论为自己做的事，是主动的行为而不是被动的行为。例如：

get dressed(穿衣服) get divorced(离婚)

get engaged(订婚) get confused(迷惑不解)

get lost(迷路) get washed(洗脸)

get married(结婚)

5.能带两个宾语和复合宾语的动词改为被动语态

(1)能带两个宾语的动词改为被动语态时，一次只能由一个宾语作主语，另一个宾语被保留下来。例如：

1)We showed the visitors our new products.(主动语态)

2)The visitors were shown our new products.(被动语态)

3)Our new products were shown to the visitors.(被动语态)

(2)能带复合宾语的动词改为被动语态时，原来的宾语补足语变为主语补足语。例如：

1)The teacher appointed him League secretary.(主动语态)

2)He was appointed League secretary.(被动语态)

6.被动语态与系表结构的区别

(1)The novel was well written.(系表结构)

(2)The novel was written by Diskens.(被动语态)

7.少数动词的主动语态有时有被动的意思

例1：The book is selling remarkably well.

例2：The song sounds very beautiful.

能这样用的动词还有read(读起来)，clean(擦起来)，wash(洗起来)，write(写起来)。

例3：My watch needs cleaning. (= My watch needs to be cleaned).

能像need这样用的动词还有：want, require, deserve, do, owe, bind等。

例4：The meat is cooking.

例5：The book written by the professor is printing.

实义动词与非实义动词

根据其含义和句子功用，动词可分为实义动词和非实义动词(包括时态助动词和情态助动词等)。如：

He bought a story book. 他买了一本故事书。(buy 为实义动词)

He has read the story book. 他已读过这本故事书。(has 为时态助动词，read为实意动词)

He should read the story book. 他应该读读这本故事书。(should 为情态助动词,red为实义动词)

上面对实义动词与非实义动词知识的内容讲解学习，相信同学们已经能很好的掌握了吧，希望同学们考试成功。

【一般过去时用法的】一般过去时表示在过去确定的时间里所发生的动作或存在的状态或者是在过去一段时间内经常性或习惯性的动作。

1）在确定的过去时间里所发生的动作或存在的状态。

时间状语有：yesterday, last week, an hour ago, the other day, in 1982等。

Where did you go just now?

2）表示在过去一段时间内，经常性或习惯性的动作。

When I was a child, I often played football in the street.

Whenever the Browns went during their visit, they were given a warm welcome.

3）句型：

It is time for sb. to do sth "到……时间了" "该……了"

It is time sb. did sth. "时间已迟了" "早该……了"

It is time for you to go to bed. 你该睡觉了。

It is time you went to bed. 你早该睡觉了。

would (had) rather sb. did sth. 表示宁愿某人做某事

Id rather you came tomorrow.

4) wish, wonder, think, hope 等用过去时，作试探性的询问、请求、建议等。

I thought you might have some. 我以为你想要一些。

比较：

一般过去时表示的动作或状态都已成为过去，现已不复存在。

Christine was an invalid all her life.

(含义：她已不在人间。)

Christine has been an invalid all her life.

(含义：她现在还活着)

Mrs. Darby lived in Kentucky for seven years.

(含义：达比太太已不再住在肯塔基州。)

Mrs. Darby has lived in Kentucky for seven years.

( 含义：现在还住在肯塔基州，有可能指刚离去)

注意： 用过去时表示现在，表示委婉语气。

1）动词want, hope, wonder, think, intend 等。

Did you want anything else?

I wondered if you could help me.

2）情态动词 could, would.

Could you lend me your bike?

一般过去式与一般现在时所表示的很相像，但一个表示过去，一个表示的是现在所发生的。

　　初中英语语法总结6

【need】didnt need to do的意思是过去不必做某事, 事实上也没做。而neednt 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"

didnt need to do表示： 过去不必做某事, 事实上也没做。.

neednt 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 didnt 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 neednt 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. mustnt have hurried B. couldnt have hurried C. must not hurry D. neednt have hurried

答案D。neednt have done. 意为 "本不必"，即已经做了某事，而时实际上不必要。

Mustnt have done 用法不正确，对过去发生的事情进行否定性推断应为couldnt have done, "不可能已经"。 must not do 不可以（用于一般现在时）。
