主谓一致时,什么时候谓语用单数?什么时候用复数
主谓一致:在英语句中,谓语受主语动支配,必须同主语在人称和数上保持一致。
*名词+as well as/no less than/but/except/with/like +其他名词,作主语时,谓语与前面的第一个名词一致.
*few/a few/both/many/several+名词复数/of+名词复数+复数
*不定代词/疑问代词(something/anything/anywhere/somewhere/where/when)+单数
语法一致原则:句子谓语动词的数取决于该句子主语的数。
1。“the+姓氏名词的复数形式”(---的成员)+复数 2。all/some/half/enough/two thirds +名词(单/复数)+单/复数 3.复数形式的名词:clothes/trousers/shorts(短裤)/glasses/scissors/gloves/chopsticks等+复数
* 计量单位(pair)+ 复数形式的名词+谓语取决于 计量单位
意义一致原则:谓语动词的单、复数形式,取决于主语所表达的概念。
1.集体名词:people/public(公共)/police/crew(船员)+复数 2。复数形式,单数意义。(news/physics/maths/politics) 3.集合名词:class/family/team/Chinese/Japanese强调总体--单数;强调个体--复数。The class has 45 students. The class are planting trees on the hill.
4.时间、距离、价格、重量的复数名词/算式+单数 Ten days is a long time.
5.the +形容词“表一类人”+复数; The rich have much money.
6.and/both--- and + 复数 7。one of/each of/none of/either of/neither of +名词+单数 8.a number(许多) +n +复数;the number (---的数量)+n +单数
9。名词+and+名词“表同一人/物用单数”“表不同人/物用复数”
The writer and the speaker are from the USA. The writer and speaker is from the USA.
就近一致原则:谓语动词的数要与它紧邻的名词/代词的数保持一致。
1.or/not--- but/either--- or---/neither--- nor---/not only--- but also--- +就近原则
2.There be+并列主语
(一)主谓一致的种类
tabletime是什么意思1.语法形式上的一致
主语为单数形式,谓语动词用单数形式;主语为复数形式,谓语动词也用复数形式。如:
The number of the students present is 200.
Jane and Mary look alike.
2.意义上一致
1)主语形式虽为单数,但意义为复数,谓语动词用复数。如:The crowd were shouting.
单数形式代表复数内容的词有:people, police, cattle等。
2)主语形式为复数,而意义上却是单数,谓语动词用单数。如:The news was so surprising.
形复意单的单词有news和一些以ics结尾的学科名称,如physics,politics, economics等。
3.就近原则
即谓语动词的单、复数形式取决于最靠近它的词语。如用连词or,either…or, neither…not, not only…but also等连接的并列主语,如果一个是单数,一个是复数,谓语动词与靠近它的主语一致。如:
Either your students or Mr. Wang knows this.
(二)主谓一致的应用
1.名词作主语
1)某些集体名词,如family, team等作主语时,如果作为一个整体看待,谓语动词用单数形式,如果就其中一个个成员而言,谓语动词用复数形式。如:
His family is a happy one.
The whole family are watching TV.
这类名词有:audience,class,club,company,crew,enemy,crowd,government,group,party,public,team等。
名词population一词的使用情况类似。“a group(crowd) of +复数名词”等短语之后的谓语动词也同样可用单数或复数,前者强调整体,后者强调各个部分。
2)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。如:
The police are searching for the thief.
3)单、复数同形的名词主语时,谓语动词应根据意义决定单、复数。如:
A sheep is over there.
Some sheep are over there.
4)名词所有格之后的名词被省略,这种情况一般只指商店、工厂、住宅等,作主语时,动词一般用单数。如:
The doctor’s is across the street.
My uncle’s is not far from here.
常见的省略名词有:the baker’s, the barber’s, the carpenter’s, the Zhang’s等。
表示店铺的名词,一般作集体名词看待,但用作主语时,谓语动词往往用复数。如:
Richardson’s have a lot of goods to sell.
5)当名词词组中心词为表示度量、距离、金额、时间、书名等复数名词时,往往可以根据意义一致的原则,把这些复数名词看作一个整体,谓语用单数形式。如:
Three years has passed since then.
6)不定代词each, every, no所修饰的名词即使以and或逗号连接成多主语时,谓语动词仍用单数形式。如:
Each boy and each girl wants to go to the cinema.
7)如果主语有more than one…或many a…构成,尽管从意义上看是复数内容,但它的谓语动词仍用单数形式。如:
More than one student has read the book.
Many a girl has been there.
但是,“more +复数名词+than one”结构之后,谓语动词一般多用复数形式。如:
More members than one are against your plan.
8)一些有两个部分构成的名词表示衣物或工具作主语时,谓语动词通常用复数形式,例如:glasses, clothes, trousers, shoes, compasses, chopsticks, scissors等。但如果主语用“a kind of, a pair of , a series of等加名词”构成时,谓语动词一般用单数形式。如:
A pair of shoes was on the desk.
9)this kind of book =a book of this kind(这种书),其谓语动词用单数;短语this kind of men =men of this kind =these kind of men(口语)(这一类人),但this kind of men的谓语动词用单数,men of this kind和these kind of men的谓语动词用复数,all kinds of后跟复数名词,谓语动词用复数形式。如:
This kind of men is dangerous.
Men of this kind are dangerous.
10)复数形式的单、复数同形名词作主语时,按意义一致原则,作用单数意义时,谓语用单数,反之,谓语用复数。这类名词有:means(方法),works(工厂),species(种类),Chinese,Japanese等。如:
The (This) glass works was set up in 1980. (这家玻璃厂建于1980年。)
The(These)glass works are near the railway station. (这些玻璃厂在火车站附近。)
当它们前面有a, such a , this, that修饰时,谓语用单数;有all, such, these, those修饰时,
谓语用复数,但means, no means, the means等词前没有以上修饰词时,可用作单数,也可用作复数。
11)如果名词词组中心词是all,most, half, rest等词语,所指的复数意义,谓语动词用复数形式;反之,用单数。如:
All of my classmates like music.
All of the water is gone.
12)在主谓倒装的句子中,谓语动词的数应与其后的主语一致。如:
Between the two windows hangs a picture.
2.由连接词连接的名词作主语
1) 用and或both…and连接并列主语,谓语动词通常用复数形式。如:
Plastics and rubber never rot.
Walking and riding are good exercises.
但是,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。如:
Truth and honesty is the best policy.
