大学英语六级必考语法汇总

大学英语六级必考语法部分汇总
主语和谓语
主语和谓语是句子的核心，它们之间有两种语序：一是主语在谓语之前称为自然语序(Natural Order);二是主语在谓语之后则称为倒装语序(Inverted Order)。

而倒装语序中又有全部倒装(Full Inversion)和部分倒装(Partial Inversion)两种情况。

首先，在全部倒装的句子中，要把整个谓语放在主语的前面去而构成倒装语序。

例如：
There are large numbers of students in the lecture hall.
(在There be…的句式中，There只是个引导词而不是主语，真正的主语是后面作表语的名词或者名词短语。

因此，There be…的句式都是全部倒装的句子。

)演讲厅里有大量的学生。

When he ran to the door, there stood a mid-aged man with a lantern in his hand .
(此句是为了"描述情节的需要"，把倒装当着修辞的手段而写成了全部倒装句。

句子的主语是a mid-aged man，谓语是stood 。

)当他向房门跑去时，那儿正立着一位手里拿着一盏灯笼的中年男人。

另外，在部分倒装的句子中，只把谓语的一部分(如情态动词、助动词、或是系动词be)放到主语的前面去，构成倒装语序。

例如：
Are you going to take part in the football match against Accounting Department on Friday afternoon? (句子的谓语是are going to take part，are是句子的谓语的一部分;句子的主语是you 。

所以，此句是部分倒装的句子。

疑问句都是部分倒装句。

)你打算去参加星期五与会计系进行的足球赛吗?
Hardly could he finish his test paper when the school bell rang .(由于语法要求的原因，本句写成了部分倒装的句子。

它的自然语序应该是：When the bell rang, he could hardly finish his test paper.)他还未做完试卷，下课铃就响了。

了解了倒装语序的构成情况后，我们再来看看倒装语序在各种不同类句子中的使用情况：
A. 在疑问句中
各种疑问句一般地说都是倒装语序。

例如：
Will they come to see us this weekend ? 这个周末他们将来看我们吗?
Are you talking about the film you saw last Monday ?
你们是在谈论你们上周一看的那部电影吗?
Can you speak another foreign language except English?
除开英语，你还能说另一种外语吗?
Where did you buy the dictionary, in the book store nearby or in Xinhua bookstore?
你在哪儿买的这本词典，是在附近的书店还是在新华书店?
She is not a student, isn‘t she ? 她不是个学生，对吗?
B. 在感叹句中
某些感叹句也用倒装语序。

例如：
Isn‘t it a beautiful garden ! 多么美丽的花园啊!
What a beautiful garden it is ! 多么美丽的花园啊!(在这种句式中，主语在谓语之前，属于自然语序。

对于主语和谓语而言，语序没有倒装。

) Have you ever seen such a naughty kid like him !
你见过那个孩子像他这么调皮!
语态：
语态是动词的一种形式，它用来表示句中主语同谓语动词之间的关系。

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谓语动词动作的执行者，被动语态表示主语是谓语动词动作的承受者。

例如：
I have repaired the radio.
我修好了收音机。

The radio has been repaired.
收音机被修好了。

The students cleaned the classroom.
学生们打扫了教室。

The classroom was cleaned by the students. 教室被学生们打扫了。

被动语态的构成：
be + 过去分词
A building was damaged by the storm.
暴风雨毁坏了一座建筑物。

Our plate was made in China.
我们的盘子是中国生产的。

My bike was stolen.
我的自行车被盗了。

常用的被动语态的时态变化如下，以ask 为例：
一般进行完成
现在I am asked, I am being asked, I have been asked 过去I was asked,I was being asked,I had been asked 将来I shall be asked, I shall have been asked
过去将来I shall be asked
被动语态的疑问句是把助动词提前到句首。

Has your TV set been repaired?
你的电视机修了吗?
Was the kite broken?
风筝破了吗?
Has the work been done?
工作结束了吗?
被动语态的否定式是在助动词后面加not.
The letter has not been sent out.
信还没有发出去。

The little boy has not been found out.
小孩还没有找到。

The cap has not been mended yet.
帽子还没有补好。

Their money has not been sent to them.
他们的钱还没有送到他们手中。

表数量
一、none 无
1) none作主语，多与of 构成短语none of。

在答语中，none可单独使用。

Are there any pictures on the wall? None.
2) none作主语，谓语动词单复数均可。

但如做表语，则其单复数与表语一致。

It is none of your business.
二、few 一些，少数
few 作主语时，谓语动词用复数，多用于肯定句。

三、some 一些
1) 可与复数名词及不可数名词连用。

2) 当做"某一"解时，也可与单数名词连用。

(= a certain)
You will be sorry for this some day.
总有一天，你会后悔这件事的。

A certain (some) person has seen you break the rule.
某些人不同意你的看法。

注意：
(1)在肯定疑问句中用some代替any。

(2)some用于其他句式中:
a. 肯定疑问句中：说话人认为对方的答案会是肯定的，或期望得到肯定回答时。

Would you like句式中，表委婉请求或建议，如：
Would you like some coffee?
b. 在条件状语从句中表示确定的意义时，如：
If you need some help，let me know.
c. some位于主语部分,
Some students haven‘t been there before.
d. 当否定的是整体中的部分时，some可用于否定句。

如：
I haven‘t heard from some of my old friends these years.
这些年我没有收到一些老朋友的信。

四、any 一些
1) any 多用于否定句和疑问句和条件状语从句中。

当句中含有任何的意思时，any可用于肯定句。

Here are three novels. You may read any. 这有三本小说，你可任读一本。

五、one, ones 为复数形式
ones必须和形容词连用。

如果替代的名词时无形容词在前，则用some, any，而不用ones。

Have you bought any rulers? Yes，I ‘ve bought some.
不定代词
would rather do
would rather not do
would rather…than…宁愿……而不愿。

还有would sooner, had rather, had sooner都表示"宁愿"、"宁可"的意思。

If I have a choice, I had sooner not continue my studies at this school.
I would rather stay here than go home. = I would stay here rather than go home.
典型例题
----Shall we go skating or stay at home?
----Which ___ do?
A. do you rather
B. would you rather
C. will you rather
D. should you rather
答案B。

本题考查情态动词rather的用法，would rather +do sth 意为"宁愿"，本题为疑问句，would 提前，所以选B。

* 不定代词
1)不定代词有
all , both, every, each, either, neither, more, little, few, much, many, another, other, some, any , one, no 以及some, something, anything, everything, somebody, someone, anybody, anyone, nothing , nobody, no one, none, everybody, everyone.等。

2) 不定代词的功能与用法
a. 除every 和no外不定代词既可用作名词，也可用作形容词。

every和no在句中只能作定语。

I have no idea about it.
b. all 都，指三者以上。

all 的主谓一致：all的单复数由它所修饰或指代的名词的单复数决定。

All goes well. 一切进展得很好。

all 通常不与可数名词单数连用，如：不说all the book，而说the whole book。

但all可与表时间的可数名词单数连用，如all day，all night，all the year; 但习惯上不说all hour，all century。

all还可以与一些特殊的单数名词连用，如all China，all the city，all my life，all the way
3) both 都，指两者。

a. both 与复数动词连用，但both…and…可与单数名词连用。

b. both, all 都可作同位语，其位置在行为动词前，be 动词之后。

如果助动词或情态动词后面的实义动词省去，则位于助动词或情态动词之前。

Who can speak Japanese? We both (all) can.
4) neither 两者都不
a. neither作主语时，谓语动词用单数。

b. 作定语与单数名词连用，但neither…nor 用作并列连词，可与复数名词连用。

其谓语采用就近原则。

c. 可用于下列句型，避免重复。

She can‘t sing，neither (can) he.
neither 与nor
d. 如前句是否定式从句，则主句用neither，而不用nor。

If you don‘t do it，neither should I. 如果你不干，我也不干。

e. 如后连续有几个否定句式，则用nor，不用neither。

He can‘t sing，nor dance，nor skate.
九种否定

e)接动词，意为“不仅是...而且还...”。

They decide to do more than talk about the rise of the cheating. Only
在学习英语的过程中，我们常遇到only与其它词或结构搭配来表达不同的意思，现将这些用法示例。

一、only引导的词组或句子放在句首作状语时，通常要用倒装结构。

如
Only in this way can you solve the problem.
只有通过这种方式你才能解决问题。

Only if you study hard can you pass the exam.
只有努力学习才能通过考试。

Only then did I realize my mistake.
只有那时我才意识到错了。

二、not only...(but also)出现在句首时，如果架连接的是两个句子，常用倒装。

如
Not only did we lose all our money,but we also came close to losing our lives.
我们不仅丢了钱，还差点把命丢了。

Not only did he speak correctly,but he also spoke easily.
他不仅说得准确，而且说得很轻松。

三、only放在不定式前面，常表示不愉快或出乎人们的意料的结果。

如
I went all the way to his home only to find hime out at a meeting.
我径直到他家里去，不料发现他出去开会了。

I hurried to the post office only to find it closed.
我匆忙赶到邮局，不料已经关门了。

She went home only to find her house burglarized.
她回到家里，发现房子被盗了。

四、“too...to...”结构中，表示否定意思，但在“only too...to...”结构中，only too = very，表示肯定意思。

如
The patient is too weak to walk.
那个病人太虚弱了，走不动。

We are only too willing to do it for you.
我们非常愿意为你做那事。

I am only too delighted to accept your king invitation.
我非常高兴地接受你的邀请。

五、在“one of + 复数名词+ 定语从句”的结构中，定语从句一般被看作修饰复数名词，谓语要用复数形式。

但在“the only one of + 复数名词+ 定语从句”的结构中，定语从句却被看作修饰“the only one”，谓语动词要用单数形式。

如
This is one of the best novels that have been published in the past two years.
这是近两年出版的最好的小说之一。

He was the only one of the boys who was given a prize.
他是这些孩子中唯一受到奖励的。

She is the only one of the girls who has been to the US.
她是那些女孩中唯一去过美国的。

六、If only 为虚拟语气的一种，表示愿望或一个未实现的条件，多用于感叹句，其主句常常省略。

如
If only she would marry me!
她要是能和我结婚该多好!
If only he had known about it!
他那时要是知道这件事该多好!
If only you could have been here earlier that day!
要是你那天再早点到这就好了。

If only there were forty-eighty hours in a day.
要是一天有48个小时就好了。

Though although
一、
1) 表示目的;它的否定式是so as not to do。

Tom kept quiet about the accident so as not to lose his job.
汤姆对事故保持沉默是为了不丢掉他的工作。

Go in quietly so as not to wake the baby.
轻点进去，别惊醒了婴儿。

2) so kind as to ---劳驾
Would you be so kind as to tell me the time?
劳驾，现在几点了。

二、
though, although
注意：当有though, although时，后面的从句不能有but，但是though 和yet可连用
Although it‘s raining, they are still working in the field.
虽然在下雨，但他们仍在地里干活。

He is very old, but he still works very hard.
虽然他很老，但仍然努力地工作。

Though the sore be healed, yet a scar may remain.
伤口虽愈合，但伤疤留下了。

(谚语)
典型例题
1) ___she is young, she knows quite a lot.
A. When
B. However
C. Although
D. Unless
答案：C。

意为虽然她很年轻，却知道许多。

2) as, though 引导的倒装句
as / though引导的让步从句必须表语或状语提前(形容词、副词、分词、实义动词提前)。

Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
注意：a. 句首名词不能带任何冠词。

b. 句首是实义动词，其他助动词放在主语后。

如果实义动词有宾语和状语，随实义动词一起放在主语之前。

Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
虽然他尽了努力，但他的工作总做的不尽人意。

3) ever if, even though. 即使
We‘ll make a trip even though the weather is bad.
4) whether…or- 不管……都
Whether you believe it or not, it is true.
5) "no matter +疑问词" 或"疑问词+后缀ever"
No matter what happened, he would not mind. Whatever happened, he would not mind.
替换：no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意：no matter 不能引导主语从句和宾语从句。

(错)No matter what you say is of no use now. (对)Whatever you say is of no use now.
你现在说什么也没用了。

(Whatever you say是主语从句)
(错)Prisoners have to eat no matter what they‘re given,
(对)Prisoners have to eat whatever they‘re given. 囚犯们只能给什么吃什么。
