主谓一致之一
主谓一致的问题看上去似乎很简单，其实使用起来却不是那么容易，有时候甚至很复杂。
这是因为在不同情况下，处理这一问题所依据的原则各不相同。就其在现代语法中的基本原则而言，通常有三个不同角度的着眼点：1、语法一致 2、意义一致 3、就近原则。
主谓一致的原则是指，主语和谓语从语法形式上取得一致：主语是单数形式，谓语也采取单数形式；主语是复数形式，谓语亦采取复数形式。例如：
A grammar book helps you learn something about the rules of a language.
（主语是单数形式，谓语也采取单数形式）
语法书帮助你学习语言的某些规则。
Grammar books help you learn something about the rules of a language.
（主语是复数形式，谓语也采取复数形式）
语法书帮助你学习语言的某些规则。
主语和谓语从语法形式上取得一致的问题远不只上述的那么简单，有许多方面的情况需要去具体地对待：
#不定式、动名词、以及从句作主语时应看作单数，谓语动词用单数。例如：
Reading often means learning .读书常意味是学习。
To read English aloud every morning does you a lot of good.每天早晨朗读英语有许多好处。
What he said has been recorded .他说的话已被录音了。
##不定代词one, every, each, everybody, everyone, one of, no one, nothing, nobody, someone, somebody, either, neither, many a 等作主语或是修饰主语时应看作单数，谓语动词用单数。例如：
Neither of my sisters likes sports .我的妹妹中没人喜欢运动。
Many a student takes a walk on campus after dinner.许多学生晚饭后常在校园里散步。
Every boy and girl shows great interest in extra-curriculum activities .每个男孩和女孩对课外活动都表现出很大的兴趣。
### 表示国家、机构、事件、作品等名称的专有名词作主语时应看作单数，谓语动词用单数。例如：
One Thousand And One Nights tells people lots of mysterious bits of folklore .
《一千零一夜》给人们讲了许多神秘的民间传说。
The United States is leading the world in science and technology .
美国常在世界科技方面领先。
The United Nations play an important role in the international affairs .
联合国在国际事务中起着重要作用。
#### a portion, a series of, a kind of, the number of等与名词构成名词短语作主语时应看作单数，谓语动词用单数。例如：
A series of high technology products has been laid out in the exhibition. 一系列高科技产品已在展览上展出。
The number of printing mistakes in some recent books often surprises people even to death.
近来一些书籍里印刷错误的数量让人吃惊得要命。
A substantial portion of the reports is missing .这些报告都没有提及实质问题。
A kind of rose in the garden smells very pleasant.这座花园里有一种玫瑰香气怡人。
##### 由some, several, both, few, many, a number of 等词修饰主语、或是由它们自身作主语时应看作复数，谓语动词用复数。另外，由and连接两个主语时，谓语一般用复数。例如：
On the seashore, some people are playing volleyball and some are lying in the sun. 海边，有些人在打排球，有些人躺着晒太阳。
Both of us are fond of watching football games .我们俩都喜欢看足球赛。
A number of will-be graduates are voluntarily going to work in the West of China. 许多即将毕业的学生打算自愿去中国西部工作。
###### 有些短语，如：a lot of, most of, any of, half of , three fifths of, eighty percent of, some of, none of, the rest of , all of等后接不可数名词、或是单数形式的名词作主语时应看作单数，谓语动词用单数；但如果后接可数名词的复数形式作主语时应看作复数，谓语动词用复数。例如：
A lot of money in the shop was stolen yesterday when the electricity was suddenly cut off. 昨天突然断电时，那家商店丢失了许多钱。
A lot of books about Investment Fund have been published recently.
最近出版了许多关于投资基金的书籍。
意义一致( Notional Concord )
这一原则是指，从意义着眼来解决主谓一致问题。有时主语形式上为单数，但意义上却是复数，那么谓语依意义也用复数形式；而有时主语形式上为复数，但意义上却是单数，那么谓语依意义亦用单数形式。
1） 当主语后面接由as well as, as much as, accompanied by, including, in addition to, more than,no less than, rather than, together with等引导的词组时，其谓语动词的形式要依主语的单复数而定。在这样的句子里，这些词所引导的词组不影响主语自身的单、复数形式，它们在句子里其实是状语。也就是说，我们完全可以将这些词组搬到句首或是放到句末去。从表面上我们也可以看出，它们与主语之间有"，"隔开。例如：
Petroleum, along with fuel gas, has recently risen in price.
最近石油和燃料煤气的价格上涨了。
The teacher, with all his students, is going to have a picnic this weekend.老师打算这个周末与学生们一起去野炊。
The students, together with their teacher , are going to have a picnic this weekend.学生们打算这个周末与他们的老师一起去野炊。
The warehouse, with all its stockings, was burned last night.
昨晚，那个仓库连同其所有的货物一起被烧毁了。
我们完全可以将上面句子中的那些词组都分别搬到句首或是放到句末去，因为它们在句子里是状语：
Petroleum has recently risen in price, along with fuel gas.
Along with fuel gas, petroleum has recently risen in price.
The students are going to have a picnic this weekend together with their teacher.
As well as the suitcase, the missing things have been found and returned to the owner.
The missing things have been found and returned to the owner, as well as the suitcase.
2) 表示时间、金钱、距离、体积、重量、面积、数字等词语作主语时，其意义若是指总量应看作单数，谓语动词用单数；但如果其意义是指"有多少数量"则应该看作是复数，那么谓语动词也应该用复数。例如：
Four weeks are often approximately regarded as one month.
人们常大约地将四个星期看成一个月。
Twenty years stands for a long period in one's life.
二十年在人的一生里意味着一个很长的时期。
Eighty dollars are enough for a student to spend on food for one week.八十块钱给一个

little,no,some, 等修饰。
I have read all the book (that) you gave me.
4)先行词被 the only, the very, the same, the last 修饰时。
He is the only person that I want to talk to.
5)先行词既有人又有物时。They talked of things and persons that they remembered in the school.
先行词是表示地点时,要根据从句的谓语动词是及物的还是不及物的。如果是及物的就用that(which),否则用where。
This is the house where he lived last year.
This is the house that (which) he visited last year.
用no sooner…than和hardly…when引导的从句表示“刚……就……”。主句中的动词一般用过去完成时,从句用过去时;而且主句一般倒装,把助动词had提到前面。例如：Hardly had I entered the room when I heard a loud noise.
代词作主语时,主谓语序不变。Here it is. Here he comes.
当句首状语为表示地点的介词词组时也常常引起全部倒装。
South of the city lies a big steel factory.
From the valley came a frightening sound.
表语置于句首时,倒装结构为“表语+连系动词+主语”。
Present at the meeting were Professor White,Professor Smith and many other guests.
Gone are the days when they could do what they liked to the Chinese people.
Among the goods are Christmas trees, flowers, candles and toys.
He has been to Beijing. So have I.
Li Wei can’t answer the question. Neither can I.
部分倒装
用于省略if的虚拟条件状语从句。Had you reviewed your lessons,you might have passed the examination.
3.用于“形容词(或名词、动词)+as(though)引导的让步状语从句中。例如：Pretty as she is ,she is not clever.
Try as he would, he might fail again.
如果从句的表语是名词,其名词前不加任何冠词。
Child as he was, he had to make a living.
用于no sooner…than…,hardly…when和not until的句型中。Not until the teacher came did he finish his homework.
用于never,hardly,seldom,scarcely, barely, little,often,at no time,not only,not once等词开头的句子。
Never shall I do this again.
Little did he know who the woman was.
6.用于以only开头的句子(only修饰副词,介词短语或状语从句时)。Only this afternoon did I finish the novel.
Only in this way can you master English.
Only when he told me did I realize what trouble he was in.
如果only后面的词组不是状语,则不用倒装。
Only Wang Ling knows this.
用于某些表示祝愿的句子。May you succeed!祝你成功!
stomach－stomachs，a German－three Germans,
an American－two Americans，man cook - men cooks;
papers 报纸, 文件 manners礼貌 drinks饮料
in a word 简言之?in other words 换句话说
have words with 与某人吵嘴
have a few words (a word) with sb.与某人说几句话
The crowd were running for their lives．
某些集体名词, 如people, police, cattle等, 只当复数看待, 谓语动词必须用复数。The police are searching for him.

d that she (should) stay in bed for a few days.
He demanded that we (should) start right away.
作advice,idea,order,demand,plan,proposal,suggestion,request等名词的表语从句和同位语从句,其谓语动词要用虚拟语气的结构“(should)＋动词原形”。例如：We all agreed to his suggestion that we(should) go to Beijing for sightseeing.
My idea is that we (should) do exercises first.
在feel, hear, notice, observe, see, watch, have, let, make等词后的补足语中,不定式不带to。但是这些句子如果变成被动结构时,就必须带to。例如：I often hear him sing the song.
He is often heard to sing the song.
注意：不定式动词在介词but, except, besides后面时,如果这些介词之前有行为动词do的各种形式,那么,这些介词后的不定式不带to,否则要带to.如：
She could do nothing but cry.
What do you like to do besides swim?
I have no choice but to go.
作定语的不定式如果是不及物动词,或者不定式所修饰的名词或代词是不定式动作的地点、工具等,不定式后面须有相应的介词。例如：He is looking for a room to live in.
There is nothing to worry about.
Please give me a knife to cut with.
There / It is no use/ good/ not any use/ good/ useless doing sth.
动词后可以用动名词作宾语,但不能用不定式:
admit,appreciate, avoid, consider, delay, enjoy, escape, excuse, feel like, finish, forgive, give up, imagine, include, keep, mention,mind,miss,practise, put off, resist, risk, suggest, can’t help, can’t stand(无法忍受)等。
I tried not to go there.(我设法不去那里。)
I tried doing it again.(我试着又干了一次。)]
mean to do 有意... mean doing意味着...
I mean to come early today.(我打算今天早些来。)
Missing the train means waiting for another hour.
(误了这趟火车意味着再等一个小时。)
allow, advise, forbid, permit
We don’t allow smoking here. We don’t allow students to smoke.
动词need,require,want作“需要”解,其后跟动词作它的宾语时,若表示的含义是被动的,必须用动名词,或不定式的被动式。例如：
The window needs(requires, wants)cleaning(to be cleaned).
在短语devote to, look forward to, pay attention to, stick to, be used to, object to,thank you for, excuse me for 等后的动词也必须用动名词形式：I look forward to hearing from you soon.
Badly polluted, the water cannot be drunk.(原因)
Being written in haste, the composition is full of mistakes.
(原因,强调写的过程,故应用现在分词一般被动式)
Having been deserted by his guide, he couldn’t find his way through the jungle.(为了强调已完成的动作)
Asked to stay, I couldn’t very well refuse.
这里 asked 可能意味着 having been asked, 也可能意味着when/since I was asked, 但用了 having been asked 就不会有歧义。
下面句中过去分词表示的时间与谓语动词所表示的时间相同，所以不能代之以强调先于谓语动词的现在分词完成被动式。例如：
Covered with confusion, I left the room.我很窘地离开了房间。
United, we stand; divided, we fall. 团结则存，分裂则亡。
He used to live in London, use(d)n’t he /didn’t he?
There used to be a cinema here before the war, use(d)n’t there /didn’t there?
Such things ought not to be allowed, ought they?
He ought to be punished, oughtn’t he?
但在正式文体中,用ought we not形式。例如:
We ought to go, ought we not?或We ought to go ,should we not?
含有情态动词must的句子表示推则,作“想必”解时,疑问部分不可用mustn’t。若前句强调对现在情况的推测,疑问部分用aren’t(isn’t)十主语,例如：You must be tired,aren’t you?若陈述部分的must表示“有必要”时,附加疑问句部分则用needn’t。例如：You must go home right now, needn’t you?
当mustn’t 表示禁止时,附加疑问部分一般用must。如：
You mustn’t walk on grass, must you?
前句谓语动词是must have＋过去分词时,若前句强调对过去情况的推测(一般有过去时间状语),疑问部分的谓语动词用didn’t＋主语;若前句强调动作的完成,疑问部分的谓语动词用haven’t(hasn’t)＋主语, 例如：
He must have met her yesterday, didn’t he?
You must have seen the film, haven’t you?
陈述句谓语部分出现否定词缀时(前缀或后缀),疑问部分仍用否定结构。例如:He is unfit for his office, isn’t he?
如果陈述部分包含有no, never, hardly, seldom, few, little,nowhere, nothing等否定或半否定词时,疑问部分用肯定形式。例如：He is hardly 14 years old,is he?
如果陈述部分的主语为everyone,someone,no one等不定代词,其疑问部分的主语可用he,也可用they。
Everyone knows his job, doesn’t he?
Everyone knows their job,don’t they?
No one was hurt,were they?
I’m late, aren’t I?
One can’t be too careful,can one(you)?
Have a cup of tea, will you?
Let’s go there,shall we? Let us go there,will you?
同位语从句跟在名词后面,进一步说明该名词的具体内容。引导同位语从句的名词主要有fact, news, promise, idea, truth等。连接词用that (不用which)及连接副词how, when, where, why等。例如：
His delay is due to the fact that the car went wrong halfway.
The news that our team has won the match is true.
She asked the reason why there was a delay.
关联词只能用whether不能用if表示“是否”的情况如下:
A)在表语从句和同位语从句中。例如：
The question is whether the film is worth seeing.
The news whether our team has won the match is unknown.
B)在主语从句中,只有用it作形式主语时,whether和if都能引导主语从句,否则,也只能用whether。例如：
Whether we shall attend the meeting hasn’t been decided yet.
It hasn’t been decided whether(if)we shall attend the meeting.
C)在介词之后。(介词往往可以省略)例如：
It all depends (on) whether they will support us.
D)后面直接跟动词不定式时。
He doesn’t know whether to stay or not.
E)后面紧接or not 时。
We didn’t know whether or not she was ready.
F)引导让步状语从句,只能用whether。
Whether you like it or not, you must do it well.
G)用if会引起歧义时。例如：Please let me know if you like it.
该句有两个意思：“请告诉我你是否喜欢”。
或“如果你喜欢,请告诉我。”用了whether就可以避免。
在下面几种情况下必须用“that”引导定语从句：
1)先行词是不定代词：all,few,little, much,something,nothing,anything等。All that we have to do is to practise every day.
2)先行词被序数词或形容词最高级所修饰。
The first lesson that I learned will never be forgotten.
3)先行词被all,any,every, each, few,

Truth and honesty is the best policy．
The girl’s teacher and friend is a young doctor．

A (great) number of修饰可数复数名词, 谓语动词用复数; a great deal of,a large amount of 修饰不可数名词, 其短语作主语时, 谓语动词用单数。

He is by far the taller of the two brothers.
某些以-or结尾的形容词进行比较时，用to代替than。superior，junior，senior等。
He is superior to Mr Wang in mathematics．
在比较从句中为了避免重复通常用that(those)，one(ones)代替前面出现的名词。that指物，one既可指人，也可指物。that可代替可数名词单数和不可数名词，而one只能代替可数名词。例如：
The book on the table is more interesting than that on the desk．
A box made of iron is stronger than one made of wood．

表示“最高程度”的形容词，如excellent，extreme，perfect等，没有最高级，也不能用比较级。
如果复数名词前有many、few，不可数名词前有much、little等表示量的形容词时，该用so而不用such。如：
I’ve had so many falls that I’m black and blue all over.
Mr White got so little money a month that he could hardly keep body and soul together.
但little不表示数量而表示“小”的意思时,仍用such。如:
They are such little children that the they cannot clean the house by themselves.
6)almost与nearly
在very, pretty, not后用nearly, 不用almost。例如：
I’m not nearly ready.
在any, no, none, never前用almost, 不用nearly。例如：

You needn’t come so early.
Need I finish the work today? －－Yes, you must.
注意：needn’t have done“表示本来不必做某事而实际上做了某事”。例如：You needn’t have waited for me.
