例1、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

答案为D。

[解析]　 这是一个定语从句。在one前是否有定冠词决定定语从句中的谓语动词的单复数形式：one of the students中的先行词是the students，定语从句中的谓语动词要用复数形式。the only one of the students中的先行词是the only one，定语从句中的谓语动词要用单数形式。又因“for three years”是完成时的标志。

例2、Professor Smith, along with his assistants, ____ on the project day and night to meet the deadline.

例6、Books of this kind ______ well.

A. sell　　　 B. sells　　　 C. are sold　　 D. is sold

第三节 巩固练习

Direction: Beneath each of the following sentences there are four choices marked A, B, C and D. Choose the best answer that completes the sentence.

1. His “Selected Poems” ______ first published in 1965.

A. were　 　　　　　　　 B. was　 　　　　　　　　　　 C. has been　　 　　　　　　 D. were

5、　 主语前有every或each修饰时，无论有几个主语，谓语动词用单数。

例如：Every teacher and every student in our school has been to the Century Park.

4、　 主语后面跟有介词with或together with 引导的短语时，谓语动词一般与前面的主语的人称和数一致。

例如：The teacher together with ten students is doing an experiment in the lab.

3、　 由数词+表示重量、里程、时间、金钱等名词所构成的复数名词主语，是当作一个整体看待的，后面用单数动词。

例如：Five minutes is too short.

　　　 Ten dollars is enough.

2、　 些名词如news, maths, physics等虽然有词尾“s”但意义上是单数，谓语动词要用单数。 例如：The news is wonderful. 　　　 Physics is an interesting subject.

1、　 集体名词看作整体时，谓语动词用单数，看作各个成员时，谓语用复数。 例如：His family isn’t large. 　　　 His family are all fond of music.

　　 出现几个主语时，谓语动词的人称单复数须和最近的主语保持一致。There be, Here be句型中动词的单复数必须与后置的第一个主语保持一致。当be后面的主语有两个或两个以上的并列成分时，be动词往往与最邻近的一个一致。

例如：There is an orange, two apples and many bananas on the table.

There are two books and a dictionary on the desk.

两个做主语的名词或代词由either…or…, neither…nor…, not only…but also等连接时，谓语动词用靠近原则。

例如：Neither you nor I am right.

Not only the students but also the teacher is going to attend the meeting.

　　　 但如果用as well as连接两个主语用靠前原则

例如：Mary as well as you is my friend.

第二节　　 实战演练

　　 主语形式是单数，但意义为复数，谓语动词根据意义要用复数；反之主语形式为复数，但意义为单数，谓语动词也用单数。如表示一笔钱，一段时间，一定重量时，这些单位虽是复数形式，但谓语动词是单数形式。

例如：It seems to me that five years is so short a time.

Two hundred dollars was spent on the books.

有些集体名词，如family, group, class等作主语时，作为整体看待，谓语动词要用单数，就其中一个个成员而言，谓语要用复数。

例如：My family is a happy one.

My family are watching TV.
