1、英语语法总结全集名词和主谓一致一、 名词的分类英语中名词主要可以分为可数名词和不可数名词。1可数名 词可数名词一般都有单复数。单数时,名词前可加不定冠词 a/an;复数时,前面可加数词,名词本身要改成复数形式。可数名词的复数有规则和不规则两种变化。规则的名词,只要在单数名词之后加“s ”,“es”或去“y”加“ies”就行,如:an umbrella, twelve umbrellas;a factory, three factories。不规则的名词变化则要靠积累记忆,如:a mouse, ten mice;a policeman, six policemen。有少数可数名词,如 sheep

2、,works(工厂), Chinese 等,它们的单复数同形:a sheep, four sheep;a chemical works, five chemical works。此外,还有一些可数名词只有复数形式,如clothes,trousers,cattle,police,people(人,人民)等。英语名词中还有一些合成词,它们的复数形式有三种可能:1)后面的部分变成复数形式:grown-ups,boy students,grandchildren。2)前面的部分变成复数形式:passers-by,lookers-on ,sons-in-law。3)前、后都变成复数形式:men doct

3、ors,women drivers。2不可数名词不可数名词没有单复数的变化,前面也不能加 a/an,或数词。但是我们可以用量词来表示不可数名词的数量,单复数表现在量词上,如:a piece of paper;two pieces of paper。在有些情况下,不可数名词也可用 a/an,表“一种”、 “某种”的意思,如 have a wonderful time,receive a good education,be made into a fine paper。有时为了表示量大,不可数名词的后面也可加“s ”,如 sands,ashes,waters等。但是我们在学习不可数名词的时候,特别

4、要记住英语中有一些名词,它们无论在什么情况下,前面都不能用 a/an,后面也不可加 “s”,如 weather,information,等。3有的名 词既可是可数名词,也可是不可数名词英语中有相当一部分的名词,既可以是可数,也可以是不可数,它们的意义有时略有不同,有时则完全不同。如:difficulty, success, time, work,paper,glass,等。4用于表示可数与不可数名词的数量“多 ”“少” 的常用词和词组跟可数名词连用的如:few, a few, many。跟不可数名词连用的如:little, a little, much。可数与不可数都能用的是:a lot of

5、 , plenty of。二、主谓一致1通常被看作单数的主语部分1)不定式、动名词和主语从句。eg To see is to believe.Seeing is believing.What he said was different from what he did.2)表示“时间”“ 距离”“金钱数量”的名词。eg.

This kind of tree(s) often grows well in warm weather.6)代词 either, neither 作主语。eg. Either of the plans is good.Neither o

7、f them was carrying a weapon.7)many a/ more than one 加单数名词,或 one out of 加复数名词作主语。eg. Many a young man has tried and failed.More than one employee has been dismissed.One out of ten thousand computers was infected with the virus. 2通常被看作复数的主语部分1)一些只有复数的名词如 clothes, trousers, police 等。eg. These trousers

8、 are dirty.但要注意比较:A new pair of trousers is what you need。2)代词 both 作主语。eg. Both of them have received high education.3需要 进行分析才能确定的主语部分1)代词 all, some,作主语。所代的名词是可数名词,就看作复数;是不可数名词,就看作单数。eg. All is ready. (= Everything is ready.)All are present. (= All the people/students. are present.)2)a lot of, lots

9、 of, plenty of, some, any, 20% of, half of.等词组作主语。所修饰的名词是可数名词,就看作复数;是不可数名词,就看作单数。eg. 70% of the surface of the earth is covered with water.90% of the graduates from the high school go to university.3)关系代词 who, which, that 作主语。由先行词决定单、复数。eg.

12、t only the students but also the teacher has to observe the rules.3)用 as well as, (together) with, like, besides, but, except 等连接的两个名词,由第一个名词决定单复数。eg.

19、 D. are working选 C。谓语的单复数跟 Professor Smith 一致,应该是单数。动词的时态与语态一、动词的时态英语的动词可以有十六种变化,但现在常用的是十二种,其中有九种是高中学生必须掌握的,还有三种只要理解。现以动词 do 为例,十二种时态的形式列表如下:一般 进行 完成 完成进行现在 do/does is/am/are doinghave/has done have/has been doing过去 did was/were doinghad done *had been doing将来 shall/will do*shall/will be doing*shall

32、here for 3 years. = I have been studying here for 3 years.而其他的一些动词,使用两种时态,意义就各不相同了。试比较: The little boy has read the text.(小男孩已经读过课文了。 )The little boy has been reading the text.(小男孩一直在读课文。 )试翻译:1)从上午九点开始我就一直在做功课。I have been doing my homework since 9 in the morning.2)今天的功课我已经做好了。I have done todays hom

34、en, belong to, take place 等)和系动词(如 become, seem, sound, look, taste,等)没有被动语态。1以动词 do 为例,被动语态的各种时态的表达方式如下表:一般 进行 完成现在 is/am/are doneis/am/are being donehave/has been done过去 was/were donewas/were being donehad been done将来 shall/will be doneshall/will be done过去将来would be done各种时态在助动词 be 上表示,动作由过去分词体现。2

35、注意在 动词词组变被动的时候,原来词组中的介词或副词不要漏掉。eg. The villagers took good care of the wounded soldier. The soldier was taken good care of by the villagers.3有些 动词既是及物动词,又是不及物动词,这些动词比较少用被动语态。eg. We begin our class at 8:00 every morning. ? Our class is begun . ?Our class begins at 8:00 every morning.4有少数 动词或动词词组可用主动形

36、式,表示(从中文里我们所感觉的)被动意义。eg. The book sells poorly.His translation reads better than yours.Who is to blame for the accident?高考真题试析:02 年 23 题He will have learned English for eight years by the time he _ from the university next year.A. will graduate B. will have graduatedC. graduates B. is to graduate选 C

37、。虽然句子的时间状语是 next year,但是“ 他从大学毕业”是以 by the time 引出的状语从句,在状语从句中,用现在时态代替将来时态。02 年 24 题I feel it is your husband who _ for the spoiled child.A. is to blame B. is going to blame C. is to be blamed D. should blame选 A。因为词组 be to blame for 这一词组用主动形式来表示中文中“该为某事受到责备”的被 动意义。02 年 29 题“Will you go skiing with m

38、e this winter vacation?” “It _.”A. all depend B. all depends C. is all depended D. is all depending选 B。It all depends.是习惯说法,意思为“要看情况而定了”,不用将来时态,也不用被动语态。03 年 32.题I thought Jim would say something about his school report, but he _ it.A. doesnt mention B. hadnt mentioned C. didnt mention D. hasnt menti

39、oned选 C。从前面一句 I though 可以看出是过 去时态,用 but 连接的两个并列句中的动作是发生在同一时间,所以后面的动词也应该是过去时态。04 年 29 题The first use of atomic weapons was in 1945, and their power _ increased enormously ever since.A. is B. wasC. has been D. had been选 C。因为句子的时间状语是 ever since,意即“自从那时起”(“ 那时”指前面讲到的 1945 年),所以是 现在完成时态。04 年 30 题The numb

40、er of deaths from heart disease will be reduced greatly if people _ to eat more fruit and vegetables.A. persuade B. will persuade C. be persuaded D. are persuaded选 D。因为 “人们”和“说服” 是动宾关系,所以用被动语态。05 年 30 题More than a dozen students in that school _ abroad to study medicine last year.A. sent B. were sen

41、t C had sent D. had been sent选 B。因为学生是被送到国外学医的,所以要用被动语态,而句末 时间状语表明要用过去时态。06 年 27 题Send my regards to your lovely wife when you _ home.A. wrote B. will write C. have written D. write选 D。这是祈使句中的状语从句的动词,所以用一般现在时态代替将来时态。06 年 32 题When he turned professional at the age of 11, Mike _ to become a world cham

42、pion by his coach and parents.A. expected B. was expecting C. was expected D. would be expected选 C。根据整个句子的意思,可以判断,是他的教 练和父母期盼马克成为世界冠军 ,所以用被动语态,时间在他 7 岁的时候,显然是过去时态。07 年 28.题“Did you tidy your room?”“No, I was going to tidy my room but I _ visitors.”A. had B. have C. have had D. will have选 A。根据前面的疑问句,

43、可判断谈论的是过去的事情,而且回答的前半句也 说明了时态:“我正要打 扫 屋子,但我有客人来 访了” 是过去时态。07 年 30 题With the help of high technology, more and more new substances _ in the past years.A. discovered B. have discoveredC. had been discovered D. have been discovered选 D。全句的时间状语是 in the past years,是典型的现在完成时态的时间状语,而且“发现 ”与“新的物质材料”是动宾关系。情态动词

44、一、can, may, must根据意思与习惯用法,我们可以把 can, may, must 分成以下两组用法,方便学习与掌握。1第一 组用法见下表(主要在初中的时候我们所掌握的):词义 肯定 否定 疑问 过去式can 能、会can cant Can.? couldmay 可以 may mustnt/may notMay.? mightmust 必须 must neednt Must.? must/had toA) cana) can 的肯定、否定、疑问及过去式的例句:eg. Computers can do a lot of things for us.Money cannot buy ev

45、erything.Can you speak French?I could run very fast when I was young.b) can 与 be able tocan 与 be able to 的意思相近,经常可以互换使用,但是 be able to 除了有一般现在与过去时态之外,还有将来、完成等时态,所以要表示将来能够或已经能够做什么事,就要用 be able to。eg. You will be able to communicate with foreigners fluently if you finish the course.The baby has been ab

46、le to one or two simple sentences.在用过去式的时候,could 与 was able to 的意思不同,could 表示的是“ 当时能够做某事”的意思,而 was/were able to 表示的是“当时能够,并且成功地做到了 ”的意思。试比较:Einstein was able to flee Germany when Hitler came into power.I could pass the examination, but I was too careless.c) could 在疑问句时用意表示请求,意 义 同 can,是一种比较客气的表达方式。e

47、g. Could you give me a hand?B) maya) may 的肯定、否定、疑问及过去式的例句:eg. You may choose anyone here you like.May I leave now? Yes, of course/Sure. Go ahead.No, you mustnt. (注:口语中也能用 cannot。)I was told that the boss might come to the office before 9 b)mustnt 与 may not.mustnt 一般是说话人表示“ 不可以”或“ 禁止”,而 may not 一般是指按

48、规定“不允许”的意思。试 比较:You mustnt leave the bike here.The sign on the wall reads, “Visitors may not feed the animals in the zoo.”c) may 可放在句首,表示 “祝愿”。eg. May our friendship last forever.d) might 有 时用在疑问句中,只是一种比 may 更客气一点,而非过去式。eg. Might I have a few words with you, sir?C) musta) must 的肯定、否定、疑问及过去式的例句:eg. E

49、veryone must obey the rules.Must I finish the work today? Yes, you must.No, you neednt/dont have to.He told me he must/had to see a doctor tomorrow morning.b) must 与 have to用 must 更强调主观上“必须” ,而 have to 更强调客观上的“不得不”。在间接引语中,主句动词是过去式时,用 had to 多,但 must 也可以用。have to 有现在、过去和将来三种时态 。c) must 有时可以表示“偏偏”“非.不可” 的意思。eg. Why must you make such a mess when the visitors are coming?2第二 组用法见下表:词义 肯定 否定 疑问 过去式 进行式can 可能/一定/ cannot Can.? cant have donecant be doingmay 可能 may may not/ may h
