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，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 doctors，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 , 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. Twenty years is quite a long time.
10 kilometers doesn’t seem to be a long distance to Mira.
300 dollars is too much for this old coin.
3）数学式子。
eg. Two plus five is seven.
4）书报杂志、国家、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. 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 of 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 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 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. The student who is talking with the principal is Tom.
The students 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。
eg. 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.
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. Tom 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.
Bread and butter is what he eats for breakfast every day.
考研真题试析：
As a result of destroying the forests, a large ____ of desert ____ covered the land.
A. number; has
B. quantity; has
C. number; have
D. quantity; have
选B。因为第一格后的名词desert是不可数名词，所以A、C两项排除；又desert做主语，谓语要用单数形式。
He is the only one of the students who ____ a winner of scholarship for three years.
A. is
B. are
C. have been
D. has been
选D。因为定语从句的先行词是由only one of修饰，所以应看成单数；另外后面有时间状语for three years，所以用现在完成时态。
The young dancers looked so charming in their beautiful clothes that we took ____ pictures of them.
A. many of
B. masses of
C. the number of
D. a large amount of
选B。空格后面的名词是复数，所以不可以选D，而many后不跟of用，所以A项排除；the number of的确是放在可数名词复数的前面，但意思是“......的数量”，不符合题意。
Where and when to go for the on-salary holiday ____ yet.
A. are not decided
B. have not been decided
C. is not being decided
D. has not been decided
选D。此句是不定式做主语，看成单数。而C项的时态不对，所以只有D。
No one in the department but Tom and I ____ that the director is going to resign.
A. knows
B. know
C. have known
D. am to know
选A。谓语动词应该跟no one一致，所以选A。
We have only a sofa, a table and a bed in our new apartment. We need to buy ____ more furniture.
A. any
B. many
C. little
D. some
选D。后面的名词是furniture，不可数。而且整句的意思是“要买些家具”,是肯定意义，所以选D。
Telephone messages for the manager ____ on her desk but she didn’t notice them.
A. were left
B. was left
C. was leaving
D. were leaving
选A。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.
A. work
B. working
C. is working
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：
（打星号的为理解项目）
1．一般现在时态
A)意义：现阶段经常反复发生的动作或现在的状态。
eg. He gets up at six every morning.
There is a big tree in the back yard.
B)常用的时间状语：always, often, usually, sometimes, seldom, never, every day, once a week,等。
C)表示一种真理、自然规律等，在间接引语中也仍然用一般现在时态。
eg. The scientist explained that the earth goes round the sun, but no one believed him then.
D)在时间、条件等状语从句中，代替将来时。
eg. If he is not busy, he will come to the party tomorrow.
E)注意第三人称单数时，动词后面要加“s”。
2．一般过去时态
A)意义：过去的动作或状态。注意，即使是刚刚发生的事情，时间非常短，也要用过去时态。如：Why! It’s you—Mary!
I didn’t know you were here!
B)常用的时间状语：yesterday, last week, 3 years ago, just now, 等。
C)动词过去式的规则变化（加ed）和不规则变化。
3．一般将来时态
A)意义：将来要发生的动作或状态。
B)常用的时间状语：tomorrow, next moth, in two weeks, 等。
C)除了用shall/will之外的将来表达法：
a) is/am/are going to do，意为“打算、准备、马上就要”。
eg. It’s going to rain.
b) is/am/are to do，意为“（计划好/安排好）要......”
eg. The new underground railway is to be opened to traffic next year.
c)is/am/are about to do，意为“马上就要”。
eg. Hurry up! The plane is about to take off.
d) 某些动词（主要是一些表示位置移动的动词）可用一般现在时态或现在进行时态表示将来的动作。
eg. The train leaves for Beijing at 8:30 this evening.
He is going to London next week.
4．现在进行时态
A)意义：表示在说话的同时或最近一个阶段正在发生的动作。
B)常用的时间状语：now, these days, at present, at the moment, 等。
C)有时可以和always, constantly, forever等时间状语连用，表示说话人的某中特殊的感情。
eg. He is always thinking of others.
Mrs Smith is constantly quarrelling with her neighbours.
D)有些瞬间动词可以用进行时态表示“马上就要......”
eg. The old man is dying.
E)英语中有些表示状态、感觉、心理活动的动词没有进行时态，如know, understand, believe, like, love, see, hear, seem, 等等。
5．过去进行时态
A)意义：表示过去某个时刻正在做的动作。
B)常用的时间状语：this time yesterday, at 9:00 last night, 等。
C)有些动词（主要是一些表示位置移动等的动词和瞬间动词）的过去进行时态可以表示过去将来的意义。
eg. I was told that she was leaving for Australia the next morning.
*6．将来进行时态
A)意义：表示将来某个时刻正在发生的动作。
B)常用的时间状语：this time tomorrow, at 9:00 next Sunday morning, 等。
eg. What will you be doing at 9:00 on June 7next year?
7．现在完成时态
A)意义：a. 表示过去某个时刻开始，一直持续到现在的动作或状态。（只有部分延续性动词，如live, work, study, 等可以表示这一意义）
eg. I have lived in Shanghai since I was born.
He has been married for half a year.
b. 表示过去做过的某一个动作对现在的影响。
eg. I have seen this film. It’s fantastic!
Jack is playing video games, because he has done his homework.
B)常用的时间状语：a. since 1990, for 9 years,等。
b. already, yet, just, now, this week, never, ever, so far, up till now, lately, in the past/last few years,等。
C)b组所表示的现在完成时态与过去时态的区别：虽然现在完成时态b组表示的动作也是发生在过去，但它强调的是与现在的关系，而过去时态只表示过去发生的动作，叙述一个事实。试比较：
eg. 1) He went to Beijing two days ago.
He has gone to Beijing.
2) Henry lost his mobile phone yesterday, but found it later.
Henry has lost his mobile phone again.
D)瞬间动词要表示“一直到现在”，不能直接用“完成时态加for”的方式，必须用其他句型。
eg. 他离开已经三天了。
He has left Shanghai. He left three days ago.
He has been away from Shanghai for three days.
It is three days since he left Shanghai.
8．过去完成时态
A)意义：表示过去某个时刻之前所做的动作，即“过去的过去”。所以一般要用过去完成时态的话，句子中或上下文一定有一个过去时态的动作或时间状语做比较，才能用。
eg. He had learned English before he went to Canada.
B)常用的时间状语：by the end of last year等。
C)在用间接引语时，主句的动词是过去时态，用来替换直接引语中的过去时态或现在完成时态。
eg. He asked the girl, “Where have you been?”
→ He asked the girl where she had been.
He said, “I cleaned the classroom yesterday.”
→ He said that he had cleaned the room the day before.
D)有些动词（如hope, wish, expect, think, intend, mean, suppose等）的过去完成时态可表示过去事实上没有实现的希望、计划等。
eg. I had hoped to attend the party, but I was too busy.
*9．将来完成时态
A)意义：表示在将来某个时刻之前将会完成的动作。
B)常用的时间状语：by the end of next year等。
eg. You will have studied English for 10 years by the time you finish high school.
10．现在完成进行时态
A)意义：表示一个动作从过去开始，一直持续到现在。（同现在完成时态的第一种意义）
B)常用时间状语：since ..., for ..., so far, up till now 等。
C)现在完成进行时态与现在完成时态的比较：
只有现在完成时态的第一种意义的那些动词，它们的现在完成与现在完成进行两种时态表示的意义相同，可以互换使用。
eg. I have studied 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 today’s homework.
*11．过去完成进行时态
意义：表示从过去某一时间开始的动作一直持续了一段时间再结束。（结束的时间点也在过去）
eg. He had been searching for the watch for a half hour when we came back.
12．过去将来时态
意义：表示从过去某一时间看将要发生的动作或状态，一般多用在间接引语中。
eg. He told me that he would read the book a second time.
二、动词的语态
英语中的动词可分为及物动词和不及物动词，以及系动词。及物动词有主动语态和被动语态；不及物动词或动词词组（如happen, belong to, take place等）和系动词（如become, seem, sound, look, taste,等）没有被动语态。
各种时态在助动词be上表示，动作由过去分词体现。
2．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?
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 graduate
B. will have graduated
C. graduates B. 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. 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。
“Will you go skiing w it h me 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。
I thought Jim would say something about his school report, but he ____ it.
A. doesn’t me ntion
B. hadn’t mentioned
C. didn’t mention
D. hasn’t 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. is
B. was
C. has been
D. had been
