主谓一致三原则
一、定义
主谓一致(Subject- Verb Agreement),指“人称”和”数方面的一致关系“一致”是指句子之间或词语之间在人称、数、性等方面保持的协调关系。在英语中最主要的一致关系是主语与谓语动词之间数的一致。谓语动词的数必须和主语的人称和数一致,这就叫主谓一致。
二、功能与用法
在判定一个句子主谓语是否一致时,要遵循下列三个原则:语法一致、意义一致和就近一致。“语法一致”也就是平常说的从语法形式上取得一致,即主语为单数形式,谓语动词也采用单数形式;主语为复数形式,谓语动词亦为复数形式。“意义一致”就是从意义着眼来处理主谓语一致问题。有时,主语形式为单数,但意义为复数,谓语动词依意义而定,也采用复数形式。“就近一致”是指谓语动词的人称和数往往和其最近的主语保持一致。
三、概述(一)语法一致原则
用作主语的名词词组中心词和谓语动词在单、复数形式上的一致,就是语法一致。也就是说,如果名词中心词是单数,动词用单数形式;如果名词中心词是复数,动词用复数形式。例如:
This table is a genuine antique.
Both parties have their own advantages.
Her job has something to do puters.
She wants to go home.
They are divorcing each other.
Mary was watching herself in the mirror.
The bird built a nest.
es home every week-end.
1. 单数主语即使后面带有with , along with, together with, like(像), but (除了),except, besides, as well as, no less than, rather than(而不是), including, in addition to 引导的短语, 谓语动词仍用单数.
如: Air as well as water is matter. 空气和水都是物质.
No one except two servants was late for the dinner. 除了两个仆人外, 没有一个人迟来用餐。
2. 用and连接的并列主语,如果主语是同一个人,同一事,同一概念, 谓语动词用单数, 否则用复数. 如:
The poet and writer .(一个人)
A hammer and a saw are useful . (两样物)
用and连接的成对名词习惯上被看成是一个整体, 如:bread and butter(黄油抹面包), knife and fork(刀叉)等做主语时, 谓语动词用单数。
3. 不定式(短语), 动名词(短语), 或从句做主语时, 谓语动词用单数. 如:
Serving the people is my great happiness.
为人民服务是我最大的幸福.
When we’ll go out for an outing has been decided.
我们什么时候出去郊游已决定了。
4. 用连接的并列主语被each, every 或no修饰时, 谓语动词用单数.
Every boy and every girl likes to go swimming. 每个男孩和每个女孩都喜欢去游泳.
No teacher and no student was absent from the meeting. 没有老师也没有学生开会缺席.
Each man and (each) woman is asked to help. 每个男人和每个女人都被请去帮忙。
5. each of + 复数代词, 谓语动词用单数. 复数代词+each, :
Each of us has something to say. 我们每个人都有话要说。
6. 若主语中有more than one 或many a/an , 尽管从意义上看是复数, 但它的谓语动词仍用单数。但more+复数名词+than one做主语时, 谓语动词仍用复数. 如:
Many a boy likes playing basketball. 许多男生都喜欢打篮球.
More than one student was late. 不只一个学生迟到
More persons than e to help us. 不止一个人来帮助我们。
7. none 做主语时,谓语动词可用单数, 也可用复数;
