8）一些由两个部分构成的名词表示衣物或工具主语时；谓语通常用复数形式，如scissors，chopsticks，compasses，shoes，trousers，clothes，glasses等。但如果主语由“a kind of ，a pair of，a series of等加名词”构成时，谓语动词一般用单数形式。例如：

A pair of shoes was on the desk .

9）this kind of book=a book of this kind（这种书），其谓语用单数；短语this kind of men=men of this kind=these kinds of men（口语）（这一类人），但this kind of men的谓语用单数，men of this kind和these kinds of men的谓语用复数。all kinds of后跟复数名词，谓语用复数形式。例如：

Men of this kind are dangerous.

This kind of men is dangerous.

10）复数形式的单、复数同形名词作主语时，按意义一致的原则，作单数意义时，谓语用单数；反之，谓语用复数。这类名词有means（方法），works（工厂），species（种类），Chinese，Japanese等。例如：

The （This） glass works was set up in l970. （这家玻璃厂建于1970年。）

The（These）glass works are near the railway station.（这些玻璃厂在火车站附近。）

当它们前面有a，such a，this，that修饰时，谓语用单数；有all，such，these，those修饰时，谓语用复数。但“means\"，“no means\"，“the means\"等词前没有以上修饰词时，可作单数，也可用作复数。

注：work作“工作”解时是不可数名词，作“著作”解时是可数名词，有单复数之分。

11）如果名词词组中心词是all，most，half，rest，part等词语，表示的是复数意义，谓语动词用复数形式；反之，用单数。例如：

All of the water is gone.

All of my classmates work hard.

12）在主谓倒装的句子中，谓语动词的数应与其后的主语一致。如：

Between the two windows hangs a picture．

2.由连接词连接的名词作主语

13）用and或both...and连接并列主语，谓语动词通常用复数形式。例如：

Walking and riding are good exercises.

Plastics and rubber never rot.

但是，并列主语如果指的，是同一个人、同一事物或同一概念，谓语动词用：单数形式，这时，and后面的名词没有冠词。例如：

A knife and fork is on the table．

Going to bed early and getting up early is a good habit．

The girl's teacher and friend is a young doctor．

Truth and honesty is the best policy。

14）当主语后面跟有as well as，as much as，no less than， along with，with， like，rather than，together with，but，except，besides，including，in addition to等引导的词组时，其谓语动词的单、复数按主语的单、复数而定。例如：

The room with its furniture was rented.

The teacher as well as the students was excited.

15）以or，either...，neither...nor，not only…but also等连接的名词（代词）作主语，谓语动词的单复数应根据就近一致的原则。例如：

Neither you nor I nor anybody else knows anything about it..

Either you or he is to go.

Tom or his brothers are waiting in the room.

3.代词作主语

16）名词型物主代词后的动词，既可以用单数，也可以用复数，这取决于它所代替的是单数还是复数。例如：

Ours（Our Party） is a great party．

our shoes are black，mine （=my shoes） are brown．

17）such，the same起指示代词作用时，应根据其所指的内容来决定单、复数。例如：

Such are his words.

Such is our plan.

18）关系代词who，that，which等在定语从句中作主语时，其谓语动词的数应与句中先行词的数一致。例如：

Some of the energy that is used by man comes from the sun.

Those who want to go please you’re your names here.

19）疑问代词who，what， which作主语时，谓语动词可根据说话人所要表达的意思决定单复数。例如：

What produce（s）heat？

Which is （are） your book（s）？

Who live next door？ It is Zhang and Liu．

Who lives next door？ It is Xiao Liu．

20）不定代词any，either，neither，none，all some，more等作主语时，有以下两种情况：

①单读用作主语时，视其在文中的意义，动词可用单数或复数形式。例如：

All are present，let's begin the meeting．

Now all has been changed．

either，neither单独作主语时，谓语通常用单数。

②后接of时，若of的宾语为不可数名词，动词当然用单数形式；若of的宾语为复数名词或代词，动词可以是单数，也可以是复数；在正式文体中，单数形式的动词更常用。例如：

None of them has（have）seen thefilm.

Do（es） any of you know his address？

4.分数、量词作主语 

21）某数词单纯表示数字作主语时，其谓语动词通常用单数形式，但是当基数词表示的不是数值而是数量时，谓语动词可用复数形式。例如：

The billion is a large number．

Twelve were boys.

英语中算术式作主语时，若是减法或除法算术式，谓语通常用单数形式；若是加法和乘法，谓语动词有时也可用复数形式。例如：

Three times five is/are fifteen.

Two and （plus） two is/are four.

Twelve divided by four is three.

Three taken from eight leaves five.

在提问加、减、乘、除得数时，如用how much，谓语动词多用单数形式；如用how many，谓语动词多用复数形式。例如：

How many are two times five？

How much is eight divided by two？

22）“分数或百分数+of+名词”构成短语，以及由“some，a lot of，lots of，plenty of，a（1arge）quantity of，the rest of，a heap of，heaps of+名词”构成短语时，其名词可以是可数名词或不可数名词。作主语时，采取就近一致的原则，其谓语动词要与短语中of后面的名词的数保持一致，这是因为短语中of后面的名词是中心词，而名词前面的量词是修饰语。例如：

A quantity of blouses were on sale．

A large quantity of beer was sold．

Plenty of English books are on the shelf．

Lots of damage was caused by fire．

Three-fifths of the workers here are women．

About three-fourths of the earth\'s surface is covered with water．
