主谓一致-讲解++练习(全)

主谓一致的用法及专项练习题

一、主谓一致三原则

主谓一致是指谓语动词与主语在人称和数上保持一致，主谓一致必须遵循三原则:语法一致原则,意义一致原则，就近一致原则。

1、语法一致原则：指主语是单数形式，谓语动词用单数形式，主语是复数形式，谓语也用复数形式。

Tom is a good student。汤姆是个好学生。

They often play football on the playground. 他们经常在操场上踢足球。

2、意义一致：指主语形式上为单数，但意义为复数，因此谓语动词用复数形式；或主语形式上为复数，

但表示单数意义,这是谓语动词用单数形式。

My family are having lunch now。我们一家人现在正吃午饭。

Twenty dollars is too expensive for the book。这本书20美元太贵了。

3、就近一致：指谓语动词用单数形式还是用复数形式，取决于最靠近他的主语。例如：

Not only the teacher but also his students like playing football.

不仅老师喜欢踢足球，而且他的学生也喜欢踢足球。

There is a pen and some books on the desk。课桌上有一支钢笔和一些书。

二、主谓一致常考题型

1、单数名词(代词）/不可数名词作主语时,谓语用单数形式；复数名词(代词)作主语，谓语用复数形式。

The desk is Tom’s. 这张桌子是汤姆的。

Some water is in the bottle. 一些水在瓶子里。

The students are playing football on the playground。这些学生正在操场上踢足球。

2、“a great/ good many+复数名词”作主语时，谓语动词用复数。但“many a+名词”作主语，意义

虽为“许多"，但谓语要用单数形式.

Many a student has been to Shanghai. 许多学生到过上海。

A great many students in our school go to college in their teens.

3、more than one+单数名词作主语，谓语用单数。

More than one student has ever been to Beijing。不止一个学生曾经去过北京。

4、表示时间、距离、金额、重量、面积、体积、容积、价格，数目，长度，数学运算等的词或短语作

主语时，这些通常作一个整体概念，谓语用单数形式.例如:

Two months is a long holiday。两个月是一个长假。

Twenty pounds isn’t so heavy。 2 0英镑并不太重。

Ten miles isn’t a long distance. 1 0英里并不是一段很长的距离。

Five minus four is one。5减4等于1。

Five minutes is enough。

Four hundred francs is a lot of money。

5、each …and each …，every …and every ；no …and no ;many a …and many a …等结构由于强调

个体行为，因此谓语动词使用单数。但是each放在并列主语之后作同位语时，谓语动词不受影响.

Each boy and each girl has got a new English—Chinese dictionary。

No sound and no voice is heard for a long time 。

Every man and every woman is at work.每个男人和女人都在工作.

7、从句、不定式、动名词或短语作主语时谓语动词使用单数形式。

Doing eye exercises is good for your eyes。做眼睛保健操对你的眼睛十分有益。

To say something is one thing , to do it is another 。（to say something , to do 是不定式)

“How do you do？” is not a question b ut a greeting 。（How do you do ？是句子，作主语) (注意：what 引导主语从句时应注意其所指的具体内容来确定谓语的单复数。）

What we need is more time ,while what they need are more doctors and medicines 。

8、what 从句作主语

1）一般来说，按照语法一致的原则，谓语动词要用单数形式；

2) what从句中动词是并列谓语,表示复数意义，主句中的谓语动词用复数；

What he said and what he did are not same.

3）what 从句作主语,有时候主句的谓语动词与主句的表语一致。如果主句的表语是复数,主句谓语动词用复数,否则用单数。

What we lack today is steel and concrete.

What they have done is considered useful to the people.

9、定语从句中的主谓一致

1) 一般情况下，关系代词作从句主语时，从句谓语动词应和先行词在数上保持一致；

2）集体名词作先行词,被视作一个整体时，关系代词用which，从句谓语动词用单数；被视作若干个体的组合时，用who作关系代词,谓语动词用复数;常见的集体名词有:family, audience，class, club，government, union，staff, team，couple, committee，crow，firm，public，orchestra，company 等。

3) 先行词是“one of +复数名词”时，从句谓语动词用复数。

如果先行词是“the right/ just the/ the only/ the very/ exactly the+ one of+复数名词"时,谓语动词用单数。

4）强调句型中，形式主语it后总是接单数is/ was；强调主语时，从句谓语动词与被强调主语部分的数

保持一致。

It is not I but Mr。Green who is in charge of this company.

I，who am your sincere friend，have never doubted the reason why you were late for my party. Each one of us who is now living in this city is destined to witness the remarkable Olympic Games。

10、当主语由“all/ some/ any/ enough/ most/ percent/ half+ of+名词”构成时，谓语动词的数与名词

的数保持一致。

当all/ some/ any/ enough/ most/ percent/ half单独作为主语时，根据意义一致的原则决定谓语动词的数。
