主谓一致三原则
吉林周德金
一、语法一致:即主语和谓语在语法上保持一致。
就是说如果主语为单数形式,谓语就用单数形式;若主语为复数形式,谓语也应用复数形式。
1. 单数名词、不可数名词、不定式短语、动词 -ing 形式、或名词性从句作主语,谓语动词用单数形式;复数主语则用动词的复数形式。
例如:
( 1 ) To say is one thing, to do is another.
( 2 ) Who will do the job hasn't been decided yet.
2. 主语是单数,其后有 with, together with, along with, as well as, besides, but, except, including, in addition to, like, no less than, rather than 或“ of +名词”等短语,谓语动词仍然用单数形式,例如:
( 1 ) The father with his two sons has gone to the cinema.
( 2 ) No one except the two boys was late for class.
( 3 ) Li Ming, rather than his classmates, has let out the secret.
3. “ more than one 或 many a +单数名词”作主语时,谓语动词用单数形式。
例如:
( 1 ) More than one person has known it.
( 2 ) Many a pilot was killed in the raid.
注:“ more +复数名词than one ”作主语,谓语则用复数形式。
例如:
More persons than one have known it.
4. “一两个”,英语中用“ one or two +名词复数”或“ a ( an )+名词单数or two ”两种形式表达,前者谓语用复数形式,后者谓语用单数形式。
例如:
( 1 ) One or two days are enough for them.
( 2 ) A day or two is enough for them.
5. and 连接两个名词作复合主语时,谓语动词用复数形式。
例如:
My father and mother are away on business.
但是,当两个名词表示同一个人、同一事物、同一概念或一个完整的东西时(其特征是 and 后的名词前无任何冠词),谓语动词应用单数形式。
例如:
( 1 ) The writer and poet has decided to be on holiday in Yunnan. (对比: The writer and the poet have decided to be on holiday in Yunnan. )
( 2 ) The hammer and sickle is flying from the flagpole.
注:当 and 连接的并列单数主语前分别有 no, each, every, many a, more than one 等修饰时,谓语要用单数形式。
例如:
( 1 ) In China every man and every woman who has a citizenship has the right to vote and to be voted.
( 2 ) Many a teacher and many a student has seen the film.
6. 不定代词 one, no one, the other, another, anyone, anybody, someone, somebody, everyone,everybody, nobody, anything, something, everything, nothing, each, either 以及被 each, every 修饰的名词作主语,尽管有些表示复数意义,但是它们的谓语应该用单数形式。
例如:
( 1 ) Is everybody here today?
( 2 ) Everything around us is matter.
注: none 作主语时,谓语动词用单数、复数均可。
例如:
None of them has ( have ) been to the Great Wall.
不过,当 none 作主语,其表语是单数时,谓语用单数;若其表语是复数,则谓语也应用复数。
另外,“ one of +名词复数”后面接定语从句时,谓语动词应该用复数(此时定语从句用于修饰前面的复数名词),而“ the ( only ) one of +名词复数”后面定语从句的谓语动词应该用单数形式(此时定语从句用于修饰 the one )。
例如:
( 1 ) He is one of the foreigners that have ever lived in China.
( 2 ) He is the ( only ) one of the foreigners that has ever lived in China.
7. 在定语从句中,当关系代词 who, which 或 that 做主语时,从句中的谓语动词应该与先行词保持一致。
例如:
( 1 ) The teacher who teaches us English is from Inner Mongolia.
( 2 ) Who is the girl that is in red shirt?
二、意义一致:即谓语动词的单复数形式不是根据语法形式,而是根据主语的内在涵义(即有时主语的单数形式表达的是复数涵义,反之亦然)确定的。
1. 有些集体名词,如: family, group, army, government, audience 等表示整体概念时,应看作单数,它们作主语时其谓语也用单数形式;但若表示组成整体的各个成员时,其谓语则应用复数形式。
例如:
( 1 ) Our family lives in the town. (整体)
( 2 ) My family like watching TV. (整体的组成部分)
2. 有些集体名词,如: people (人们), police, cattle, personnel (全体人员),militia (民兵),及以 -ch, -sh, -ese 结尾的表示“……国人”的词作主语时,谓语应该用复数形式。
例如:
( 1 ) The police are after a murderer.
( 2 ) The Chinese ( people ) are kind and friendly.
注: people 作“民族”解时,其单数形式为 people ,复数形式为 peoples 。
当它作主语时,谓语动词的单复数形式应视情况而定。
例如:
( 1 ) The Chinese people is a great people.
( 2 ) 56 people make up the big family of China.
3. 由两个部分组成一个整体的物品名词(如: shoes, glasses, boots, socks 等)作主语时,谓语要用复数形式。
例如:
( 1 ) The shoes are not expensive.
( 2 ) His football socks are broken.
注:表示物品的名词用量词表示具体数量时,其谓语形式应与量词的数保持一致。
例如:
That pair of trousers was sold out, but these kinds of trousers are still on the counter.
4. 复数名词或短语表示时间、距离、长度、价格、数字、度、量、衡,以及国名、山脉、群岛、瀑布、书名、剧名、单位或报刊名称等的复数名词作主语,其谓语动词要用单数形式。
例如:
( 1 ) Ten years is a moment in history.
( 2 ) The Arabian Nights is a very interesting story-book.
( 3 ) The United States is the only superpower in the world now.
5. “分数(百分数)+ of +名词”以及“ all ( most, some, any, half, a lot, the rest ) +of +名词”作主语时, of 后的名词是单数,谓语用单数形式;若 of 后的名词是复数,谓语就用复数形式。
例如:
( 1 ) Three-fourths of the surface of the earth is water.
( 2 ) Ten percent of the apples are bad.
( 3 ) All of the work has been done.
6. the 与某些形容词搭配表示一类人时,如 the dead, the blind, the old, the rich, the wounded 等,谓语用复数形式。
例如:
( 1 ) The old are taken good care of.
( 2 ) The rich are getting richer and the poor are getting poorer in some countries.
但是 the 与某些抽象名词或形容词搭配表示抽象概念时,如: the gold, the difficulty, the unknown, the love, the beautiful, the impossible, the unusual ,谓语动词要用单数形式。
例如:
( 1 ) The love lives forever.
( 2 ) The unusual is what he likes.
7. 以 -s, -es, -ics 结尾表示学科、疾病、游戏等名词以及 means, works (工厂), news 等作主语时,谓语动词要用单数。
例如:
( 1 ) Mathematics is difficult to study.
( 2 ) Diabetes (糖尿病) is a very serious disease.
8. 关系代词 who, that, which 引导的定语从句,谓语动词的单复数形式应与先行词的数保持一致。
例如:
( 1 ) I, who am your new teacher, will teach you chemistry.
( 2 ) Is this the book that was bought yesterday? (比较: Are these the books that were bought yesterday? )
9. 疑问代词 what, which, who 作主语,谓语动词的单复数形式应依据说话人的意图而定。
例如:
( 1 ) Which has been chosen? (比较: Which have been chosen? )
( 2 ) Who lives in the room? (比较: Who live in the room? )
10. “ a ( the, this, that ) kind / sort / type of +名词”作主语,谓语用单数形式。
但若是“ these ( those, all, many, some ) kinds (有时用 kind ) of +名词”作主语,谓语应用复数形式。
例如:
( 1 ) This kind of book is sold in that shop.
( 2 ) Many kinds of shoes are sold in that shop.
注:“名词+ of + a ( the, this, that, these, those, all, some, many 等)+ kind ( s )”结构作主语,谓语动词的单复数形式则与名词的数一致。
例如:
( 1 ) Book of this kind is sold in that shop.
( 2 ) Apples of these kinds are sour.
11. “ a + 单数名词+and a half ”和“ one and a half+ 复数名词”作主语,谓语用单数形式。
例如:
One and a half pears has been left on the table.
三、就近一致:这一原则是指如果句子中有两个或两个以上的主语时,谓语动词的单复数形式要根据靠近它的主语的单复数来确定。
主要有以下两种情况:
1. or, either … or … , neither … nor … , not only … but also … , not … but …等连接并列主语时。
例如:
( 1 ) Not his parents but he doesn't want to go.
( 2 ) Neither you nor I am a stranger here.
但是在疑问句中,谓语动词的单复数形式则应根据两个并列名词中的前一个名词的单数来确定。
例如:
( 1 ) Do his parents or he want to go?
( 2 ) Does neither he nor his classmates know the secret?
2. There be +多个名词作主语,谓语动词常与最靠近 be 的名词的单复数一致。
例如:
( 1 ) There is an apple, two pears and some oranges on the plate.
( 2 ) There are three students, two strangers and our headmaster talking together.
常见的结构有: share ( in ) sth. (分享、分担), share ( in ) sth. with sb. (和某人分享、分担)。
share 后可跟表示具体概念的名词,也可跟表示抽象概念的名词,如 hope, interest, belief, faith 等。
例如:
Let Harry play with your toys as well, Clare. You must learn to share.。
