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 docto
3、rs，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，特别要记住
4、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 , pl

6、子。 eg. Two plus five is seven.4）书报杂志、单位的名字。 eg. The Times is published daily. The United States is a big country.5）前面用a kind of, a sort of或this kind of, this sort of等词组的名词。 eg.

7、hem 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.

8、e 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 of
9、, 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. The student who is talking with the principal is Tom. The s
10、tudents who have chosen physics will have a test tomorrow. 但要注意one of .与only one of.所修饰的先行词。 eg. He is one of the students in our class who have been to Beijing. He is the only one of the students who has been to London.4）一些表示集体意义的名词如family, team, class等。 当这些名词强调的是一个整体时，看作单数；当它们强调的是这个集体中的成员时，看作复数。 e
11、g. Happy families are all alike; every unhappy family is unhappy in its own way. My family are all early risers.4出现在句首，用连词或介词连接的两个名词或词组1）用both.and.连接的两个名词看作复数。 Both Kate and Jean are football players.2）用or, either.or., neither.nor., not only.but also.连接的两个名词，由靠近动词的名词决定单复数。 Either you or I am to go.
12、Not 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. His eyebrows as well as his hair are now white. No one but these two peasants has been there.实际上这些都是介词短语提前，不是并列的主语。4）用and连接的两个名词有几种情况： a)看作复数。 eg. T
13、om and Mary are primary pupils. b) 在有every . and every ., each . and each . 的时候；或用and连接的两个名词表示的是一件东西或一个人时，看作单数。 eg. Every boy and every girl in our country has the right to go to school.

18、。句子的主语是messages，是复数，另外它与动词“留（在桌上）”的关系是被动。Professor Smith, along with his assistants, _ on the project day and night to meet the deadline.

36、nt?考研真题试析：He will have learned English for eight years by the time he _ from the university next year. A. will graduateB. will have graduated C. graduatesB. is to graduate选C。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。I feel it is your husband who _ for the spoiled child. A
37、. is to blameB. is going to blameC. is to be blamedD. 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。“Will you go skiing with me this winter vacation?” “It _.” A. all dependB. all dependsC. is all dependedD. 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。I thou
38、ght Jim would say something about his school report, but he _ it. A. doesnt mentionB. hadnt mentionedC. didnt mentionD. hasnt mentioned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。The first use of atomic weapons was in 1945, and their power _ increased enormously ever since. A.
39、 isB. wasC. has beenD. 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。The number of deaths from heart disease will be reduced greatly if people _ to eat more fruit and vegetables. A. persuadeB. will persuadeC. be persuadedD. are persuaded选D。因为“人们”和“说服”是动宾关系，所以用被动语态。More than a
40、dozen students in that school _ abroad to study medicine last year. A. sentB. were sentC had sentD. 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。Send my regards to your lovely wife when you _ home. A. wroteB. will writeC. have writtenD. 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。When he turne
41、d professional at the age of 11, Mike _ to become a world champion by his coach and parents. A. expectedB. was expectingC. was expectedD. 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。 “Did you tidy your room?”“No, I was going to tidy my room but I _ visitors.” A. h
42、adB. haveC. have hadD. will have选A。根据前面的疑问句，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。With the help of high technology, more and more new substances _ in the past years. A. discoveredB. have discoveredC. had been discoveredD. 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
43、，而且“发现”与“新的物质材料”是动宾关系。情态动词一、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cancantCan.?couldmay可以maymustnt/may notMay.?mightmust必须mustneedntMust.?must/had toA) can a) 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 canno
44、t buy everything.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
45、 able 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。 eg. 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
