名词单复数及句中名词与动词的一致
一、常见错误及辨析
1.A box of table tennis balls are on the table. (错误)
A box of table tennis balls is on the table. (正确)
解析:a+表示群体单位的名词(basket, body, box, chain, flock, list, stack,set等)+of+复数名词作主语,谓语动词用单数。
2.Bryant, with his two classmates, are in the car. (错误)
Bryant, with his two classmates, is in the car.(正确)
解析:主语和动词之间有插入语时,不能根据插入语的单复数,而应该根据真正主语的单复数来决定动词的形式。
3.There are a mouse, two cats and three bones in the picture. (错误)
There is a mouse, two cats and three bones in the picture. (正确)
解析:在there be 结构中,当充当主语的是一组名词时,be 动词应该与第一个名词保持数的一致,即就近原则。
符合本原则的还包括由关联连词连接的两个名词作主语
时的情况,如“either…or, neither…nor, as…as, not so…as”
4.None of the students are from China.
None of the students is from China.
解析:在none, neither 和either +of +复数名词的结构中,动词应该是单数形式。
5.Her clothes is certainly expensive. (错误)
Her clothes are certainly expensive. (正确)
解析:有些由两部分构成的工具或器械的名称,疾病的名称等本身就是复数形式,它们在充当主语时,动词应该用复数。
有些名词形式上是复数,但是通常只是当作单
数看待,如:politics, physics, economics, news
6.The woman servants are all high school graduates.(错误)
The women servants are all high school graduates.(正确)
解析:由woman, man 后面加上名词构成复合名词在变成复数的时候需要将两个复合成分都变成复数;一般复合名词构成复数时只需要将主体名词变成复数就可以,如:
son(s)-in-law passer(s)-by editor(s)-in-chief; 没有主体名词的复合名词构成复数
时直接在最后一个词后面加复数词尾,如:go-between(s) draw-back(s)
7. Fifty kilometers seem like a long walk to me. (错误)
Fifty kilometers seems like a long walk to me. (正确)
解析:数词+表示时间、重量、长度、价值等单位的复数名词作主语时,如果作整体看待,谓语动词用单数形式.
9. This pair of gloves are wearing out. (错误)
This pair of gloves is wearing out. (正确)
解析:this/a pair of +复数名词(表示成对的东西)作主语时,谓语用单数。
The pair+of +复数名词时,谓语用复数。
10.A quarter of a dollar are 25 cent. (错误)
A quarter of a dollar is 25 cent. (正确)
解析:half, the rest, proportion, quarter等+of+单数名词作主语时,谓语用单数,+of+复数名词时,谓语用复数。
