5) 有些相当于及物动词的动词词组,如“动词+介词”,“动词+副词”等,也可以用于被动结构,但要把它们看作一个整体,不能分开。其中的介词或副词也不能省略。

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。

返回动词的时态目录
1110 比较一般过去时与现在完成时
1)一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。
2)一般过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。

注意:It was the third time that the boy had been late
2)This is +形容词最高级+that…结构,that 从句要用现在完成时。例如:
This is the best film that I've (ever) seen 这是我看过的最好的**。
典型例题
(1) ---Do you know our town at all
---No, this is the first time I ___ here
A was B have been C came D am coming
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

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
返回动词的时态目录
1112 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

1114 延续动词与瞬间动词
1) 用于完成时的区别

初中所有英语语法

初中语法汇总:8种时态、3种从句、2种语态。

一、八种时态:

1一般现在时

表示平时经常的、习惯性的动作,描述平时所处的状态,表达平时存在的特征、有规律的状态等。

I drink water every day 我每天都喝水。(习惯性动作)

2现在进行时

表示正在发生的动作。经常用到的结构有be doing sth 常和now, look, listen这些词连用。

She is dancing 她正在跳舞。

3一般过去时

由谓语动词的过去式表示,也就是说动词词末要加-ed(除不规则动词外)。常和一般过去时连用的过去时间状语有:last night (week ,month , year , century , etc) , yesterday ,yesterday morning (afternoon , evening) , in 1999 , two hours ago等等。

4一般将来时

表示将来要发生的动作或计划。结构有主语+will+动词原形和主语+be going to do。

I will go to the zoo in this weekend 这个周末我将要去动物园。

5现在完成时

表示过去已经完成的动作对现在造成影响或后果。

I have watched that movie 我已经看过那部**了。

6过去进行时

表示过去某个时刻或时间段正在进行的事情或动作。结构是was/were+现在分词。

What was he doing at home last night 昨天晚上他在家干什么?

7过去将来时

表示过去的某时以后将要发生的动作。

He didn't expect that we would all be there 他没料到我们会全在那儿。

8过去完成时

表示在过去某一时间或动作之前已经发生或完成了的动作,也就是“过去的过去”。主要结构是助动词 had +过去分词,had 通用于各种人称。

She had finished writing the report by 9:00 this morning 今天早晨9点之前,她已经写完了报告。

二、三种从句

1宾语从句

在复合句中,由一个句子充当宾语,这个句子叫做宾语从句。宾语从句主要有三种类型,分别是that引导的宾语从句、if或whether引导的宾从、连接代词和连接副词引导的宾语从句。 常见的宾语从句引导词:that、if、whether、what、who、where、why和how。

2定语从句

定语从句在中考和高考中出现的频率都非常高。在复合句中,修饰名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词。定语从句一般放在先行词的后面。常见的关系代词包括that,which,who(宾格whom,所有格whose),as 等,关系副词包括where,when,why等。

3状语从句

状语从句就是由一个句子在复合句中充当状语。所以状语从句又可以分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句等等。每种状语从句都有特定的引导词:

地点状语从句:where,wherever

时间状语从句:when, while, as, before, until, till, since

原因状语从句:because, since,as, now that, not that…, but that…, seeing that, considering that, in that

目的状语从句:so, so that, in order that, that, to the end that, in case,for fear that,lest

结果状语从句:sothat, such that, so that, with the result that

条件状语从句:if,unless,if only,only if,in case,suppose/supposing(that),provided/providing(that),on condition that,so/as long as

方式状语从句:as, as if, as though

让步状语从句:though, although, as, even if, even though, whether, no matter whetheror, no matter with

比较状语从句:asas, not as/soas, than, the morethe more

三、两种语态

在主动语态中,主语后面接人(be +动词原型),被动语态(be+动词过去分词)。在主动语态中,主语是谓语动词的使动方。在被动语态中,主语是谓语动词的受动方。学习被动语态时,不仅要知道被动语态的各种语法结构,还要知道在哪些情况中使用被动语态。

词法

初中英语语法有主谓一致,被动语态等。

被动语态根据时态的不同,可分为以下几种类型:

一般现在时:am、is、are+done;般过去时:was、were+done。

现在进行时:am、is、are+beingdone过去进行时:was、were+beingdone。

将来时:will、would+be done,be going to be done,be to be done

现在完成时:have、has+been done。

过去完成时:had+been done。

将来完成时:will+have been done。

主谓一致指的是句子的谓语动词与其主语在数上必须保持一致,句子的主语是第三人称单数,其谓语动词须用单数,主语是复数,则谓语动词用复数。

主谓一致的三个原则。

英语中的主谓一致主要遵循三个原则:意义一致原则、语法一致原则和就近原则。这三个原则堂堂发牛矛盾,但当发生冲突时,意义一致原则为优先考虑的原则。

怎么学习英语语法:

单词的学习和朗读课文是基础,没有单词的学习和课文的朗读是学不好语法的。也就是说语法的学习不可独立来看。

语法又分为词法和句法。词法是指具体一个词语的用法,所以词法是很多的。比如forget可以接to do,也可以接doing。语法的学习就是理解句子的成分,结构。通过句法的学习可以准确理解句子的含义。

简单句的学习要容易的多,如果遇上复合句,就要复杂的多,比如主语从句,宾语从句,同位语从句等。

语法的学习还要学习时态,比如一般过去时,一般将来时,一般现在时等都要借助时间来准确理解。

语法的学习最好借助练习题来完成,语法知识只有在运用中才能检验自己是否真的学会了。是否可以转化成自己的能力。
