句子复数用英语怎么说单词怎么读_句子复数用英语怎么说单词怎么读的

主要看句子的主语和谓语。

主语如果是复数代词we,you,they,these,those或有复数名词(通常有s词尾),句子就是复数。

主语如果含有both...and...,句子就是复数。

......

谓语部分,如果助动词是are,he,were,*do,或谓语动词是be的are形式,句子就是复数。

......

关于这个问题,最好还是看看语法书上有关主谓语的一致问题。

*****************************************************

主谓语的一致:

1、主语和谓语基本保持单复数的一致,即:主语是可数名词单数或不可数名词时,谓语动词用单数形式:

The computer was a great invention. The water in the glass is very cold.

2、集体名词(如family, class, team, group, row, police, school等)做句子主语时,

① 如果表示整体概念,则谓语用单数形式,如:Class Three is a very good class.

② 如果表示其中的所有成员时,则谓语用复数形式,如:Class Three he a map of China.

3、Chinese,Japanese,fish,sheep,people等表示单个时谓语用单数,表示许多时,谓语用复数。如:

There is a sheep in the yard. / There are some sheep in the yard.

4、maths,news等虽然有s结尾,但不是复数,因此谓语仍用单数:The news is very exciting.

5、glasses,shoes,socks,trousers,gloves等名词往往用复数形式,故谓语用复数。如:

The trousers are very cheap and I want to take them.

6、a lot of 后跟名词复数时谓语用复数形式,跟不可数名词时谓语用单数形式。如:A lot of students are playing baseball now. A lot of time was wasted on that work.

7、and 连接两个名词做主语时,谓语原则上用复数,但是两个名词若构成一个整体事物时,谓语则用单数。如:The teacher and his son are picking les now. Fish and chips is very famous food.

8、 there be 句型中be的单复数一般由靠近的名词决定。如:There is a table and four chairs in the room.

9、用both…and…连接两个事物做主语时,谓语一般用复数。如:Both you and I are required to be here tomorrow.

10、主语中含有with的短语时,谓语单复数由with之前的人物决定。如:A woman with a 7-year-old child was standing at the side of the road.

11、either…or…或者 neither…nor…连接两个人物做句子主语时,谓语用就近原则。如:Either you or he is right. / Neither you nor I am going there.

12、表示一段时间或长度概念的复数名词做主语时,谓语一般用单数。如:Two months is not a short time. Two thousand kilometers is quite a long distance(距离).

13、主语中含有half of… / (three quarters)of… / all (of) the ….等词语时,谓语的单复数由名词确定,如:Over three quarters of the information on the Internet is in English. / A third of the students were playing near the lake. / All of the water in these rivers has been polluted.

但是,population一词又有特殊情况: What’s the population of China? / Three quarters of the population in this city are Arabs(阿拉伯人).

请问下英语中的单词怎么变成复数后面应该加什么.有规则吗?

你是说“主谓一致”吧

比如说:这个苹果是我的。

This le is mine。

而 这些苹果是我的. 就该是:

These les are mine。

你讲的应该是这个地方is 和are 的区别是不是?

is 就是单数的动词了,are就是复数的。

再给你举个例子:

他骑车上学. He goes to school by bike.

他们骑车上学. They go to school by bike.

goes是动词go 的单数形式。

呵呵,写这么多,希望能帮得上。如果真的是,详细的你可以查看“主谓一致”这个语法项.

英语句子单数改复数如何改

1) 一般情况加s

例如:map-maps boy-boys girl-girls pen-pens bag-bags car-cars

(清辅音后读/s/,浊辅音和元音后读/z/,/s/、/z/、/d?/等音后发/iz/)

2) 以s, sh, ch, x结尾加es,读/iz/。

例如:bus-buses watch-watches box-boxes brush-brushes

3) 以辅音字母+y结尾,变y为i再加es,读/iz/。

例如:baby---babies city-cities country-countries

4) 以y结尾的专有名词或元音字母+y结尾的名词变复数时,直接加s,读/z/

monkey---monkeys holiday---holidays Mary---Marys(专有名词)

5)以辅音字母+o结尾的,加es,读/iz/。

例如:potato- potatoes tomato-tomatoes hero-heroes Negro-Negroes

[1]

7) 有些以辅音+o结尾的名词,直接加s,读/z/.

例如:piano-pianos photo-photos alto-altos soprano-sopranos quarto-quartos(四开本)

8)有些以f或fe结尾的,把f或fe变ve加s,例如:leaf-lees shelf-shelves

比如:they

are

boyes。改成单数就是he

is

a

boy.
