主谓一致是比较复杂的现象,要注意以下一些问题。
1、一些有两个部分构成的名词表示衣物或工具作主语时, 谓语通常用复数形式:glasses, clothes, trousers, shoes, compasses, chopsticks, scissors等。
2、并列主语如果指的是同一个人、同一事物或同一概念时, 谓语动词用单数形式, 这时and后面的名词没有冠词。
例如: The girl’s teacher and friend is a young doctor.
Going to bed early and getting up early is a good habit.
A knife and fork is on the table.
3、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 teacher as well as the students was excited.
The room with its furniture was rented.
4、A (great) number of修饰可数复数名词, 谓语动词用复数; a great deal of,a large amount of 修饰不可数名词, 其短语作主语时, 谓语动词用单数。
5、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:Those who want to go please sign your names here.
6、某些集体名词, 如people, police, cattle等, 只当复数看待, 谓语动词必须用复数。The police are searching for him.
7、一些典型例句
Five minutes is enough to do this exercise.
Each boy and each girl wants to serve the people in future.
More than one student has seen the film.
Many a ship has been damaged in the storm.
More members than one are against your plan.
