论文部分内容阅读
1.有时主语与谓语动词之间插入一个介词短语修饰主语，该短语对谓语动词的单复数不产生影响。如：
Several theories on this subject have been proposed.
The danger of forest fires is not to be taken lightly.
2.当主语后面跟有(along/together) with, like, in addition to, as well as, more than, rather than等引导的词组时，其谓语动词的单复数不受这些词组的影响。如：
The rock singer, along with his bodyguards, was rushed away from the theater.
Helen as well as I is eager to see the performance.
Tom, more than other children, is anxious to go there again.
My license, rather than my credit cards, was lost.
3.“名词/数词+of+名词”结构与谓语动词的一致有以下情况：
1)“one+of/out of+复数名词”结构作主语时，谓语动词一般用单数形式。如：
One of the students in this class is from Tibet.
2)“a pair+of+复数名词”结构后，谓语动词多用单数形式，强调事物的整体性。如：
A pair of gloves is a nice present for her because it is cold now.
3)“(a) part+of+名词”结构中，如名词为单数形式，一般要求谓语动词用单数形式；如名词为复数形式，一般要求谓语动词用复数形式。“parts+of+名词”结构后的谓语动词用复数形式。如：
A part of the story is not true according to the witness.
A part of the apples are bad.
Parts of the new book are very instructive.
4)“a group+of+复数名词”结构后，谓语动词多用单数形式，也可用复数形式。前者强调整体概念，后者强调各个组成部分。如：
This group of chemicals behaves in the same way. (强调group这一整体)
This group of chemicals behave in the same way. (强调group中的各成分)
5)“a number+of+复数名词”结构后，谓语动词多用复数形式；“the number+of+复数名词”结构后的谓语动词用单数形式。如：
A large number of/Large numbers of people have come to see the exhibition.
The number of stamp-collectors is growing very quickly.
同样，“an average/total+of+复数名词”结构后的谓语动词用复数形式；“the average/total+of+复数名词”结构后的谓语动词用单数形式。如：
An average of 3,000 letters a month are received by the newspaper’s office.
The total of letters received last month was 3,000.
6)“a lot/mass…+of+复数名词”结构后的谓语动词一般用复数形式；如果名词是不可数的，谓语动词则用单数形式。如：
A mass of workers were working in that factory.
A lot of money was spent for travel.
7)“this kind/sort…+of+名词”结构后的谓语动词一般用单数形式；如名词为复数形式，谓语动词也可用复数形式，以强调名词的复数概念。如：
This kind of bird has been discovered by them.
The kind of apples you eat are large and sour.
8)“the rest+of+名词”结构中，如果名词是单数形式，谓语动词一般用单数形式；如果名词是复数形式，则谓语动词一般用复数形式。如：
The rest of the story needs no telling.
Mike stayed at home and the rest of the boys were out.
9)“分数或百分数+of+名词”结构中，如果名词为复数形式，谓语动词用复数形式；如果名词为单数形式，谓语动词则用单数形式；若强调分数或百分数的抽象概念，谓语动词用单数形式。如：
Over 30% of the students were absent from the meeting.
Over three quarters of the city was destroyed in the war.
Only about one third of the class is going to make it next year.
10)“most/plenty+of+名词”结构中，如果名词是单数形式，谓语动词一般用单数形式；如果名词是复数形式，则谓语动词一般用复数形式；如果为集体名词，则根据该名词是指整体还是指个体而定。如：
Most of his time was spent traveling when he was young.
Plenty of chairs are needed for the meeting.
Most of the population was young. (population指整体)
Most of the audience were college students. (audience指个体成员)
11)当none of后面接的是可数名词时，谓语动词用单复数形式都可以；如果接的是不可数名词，则只能用单数形式。当either/neither of…构成的短语作主语时，谓语动词通常用单数形式（在口语中也用复数形式）。如：
None of the books has/have been placed on the shelves.
None of the blame was your brother’s.
Neither of the members is/are going to give up the chance.
