第二章 主谓一致
句子的谓语动词和句子的主语应在数方面保持一致。主谓一致的基本原则是：主语是单数，谓语动词用单数形式；主语是复数，谓语动词用复数形式。句子的主语有以下几种类型：
1．带后置定语型。其谓语动词的形式依主语的单复数而定，与后置定语无关。
（together）with …
except / but …
S + besides … V
rather than …
as well as …
A library together with a lot of books has been given to our school as a gift.
Two pilots as well as all the passengers were killed in this plane crash.
两个飞行员连同所有旅客都死于这次空难。
2．部分-整体型。其谓语的单复数，由整体部分决定。
70 percent
two-thirds
part of the / one’s + n +V
half （整体）
all
the rest
1）About 70% of the surface of the earth is covered by water.
2）Part of the books are worth reading, but the rest（of them）are of no value.
※注：all单独作主语时，All指人谓语用复数。All指物或事情谓语用单数。
1）All are eager to reach an agreement. 所有的人都急于达成协议。
2）All is going well. 一切都进展顺利。
3．定语仅能修饰单数名词型，其谓语动词用单数。
Each / Every
Either / Neither
Another + n（单数）+ V
Many a
More than one
More than one graduate wants to go to work in Western China.
不止一个毕业生要求去中国西部工作。
Many a day has passed since the boy was lost. 那个男孩失踪已有许多天。
4．就近一致型。下列连词连接两个主语时，及there be句型有多个并列主语，谓语应与最靠近的主语保持一致。
A or B 1）Either you or I am to meet them at the station.
Either A or B 不是你就是我要去车站接他们。
Neither A nor B 2）Not only the teacher but also his students object to the plan.
Not only A but also B 3）There is an air-conditioner and two computers in his office.
There be A, B and C 在他办公室有一台空调和二台电脑。
5．需记住的其他规则
Either
1）Neither of + n 作主语，谓语用单数。
Each
None of + n（复数）作主语，谓语用单数或复数均可。
None of + n（单数）作主语，谓语用单数。
Either of the answers is right. 两个答案中有一个是对的。
None of the cars was / were damaged. 这些车都没有受损。
None of the food has gone bad. 食物没有变质。
2）a number of + n（复数）作主语，谓语用复数。
the number of + n（复数）作主语，谓语用单数。
A large number of students are from the south. 很多学生是南方人。
The number of students in our school has gone up to 3000.
我校学生数已上升到3000人。
3）关系代词作主语，定语从句谓语动词的形式取决于其先行词的单复数。
He is one of the few persons who have a good knowledge of Italian.
他是精通意大利语的少数人之一。
在以上句子中，persons是who的先行词，从句谓语动词用复数。
（比较）He is the only one of the boys who was given a prize.
他是这些孩子中唯一受到奖励的。
当one之前有the only修饰时，one是who的先行词，从句谓语动词用单数。
4）单个动名词，不定式或主语从句作主语，谓语动词用单数。
两个并列的动名词，不定式或主语从句作主语，谓语动词用复数。
When and where to hold the meeting isn’t decided yet.（一个不定式作主语）
What I say and what I think are none of your business.
我说什么，想什么与你无关。（两个并列主语从句作主语）
5）each, any, every, no构成的复合代词都当作单数看待。
Someone is asking you on the phone. 有人在打电话找你。
注：复合代词作主语，反意疑问句的主语通常用they，也可用he。
Everyone was present at the meeting, weren’t they / wasn’t he ?
Someone has known the news, haven’t they / hasn’t he ?
6）以“s”结尾的书刊名、国名、机构名和学科名作主语，谓语用单数。
The United Nations was set up in 1942. 联合国建于1942年。
The Canterbury Tales was written by Chaucer. 《坎特伯雷故事集》是乔叟写的。
Economics is my major. 经济学是我的主修课程。
7）某些形容词或分词和定冠词the连用表示某类人作主语，谓语用复数。
The sick have been cured and the lost have been found.
病人得到医治，失踪的也已找回来了。
8）由and连接两个单数名词作主语，谓语动词用复数形式。
English and Chinese are quite different languages.
若and并列的主语在意义上指同一个人，同一概念或对立统一的事物，谓语动词用单数。
The manager and secretary is as busy as a bee all day. 那位经理兼秘书整天忙忙碌碌。（两个名词共用一个冠词，指同一个人）
War and peace is a contant theme in history. 战争与和平是历史永恒的主题。（对立统一的一对事物）
9）单复数同形的名词如deer, means；集合名词如family作主语，如何决定谓语动词的单复数，请见第四章冠词。
