句子的复数形式怎么变了_句子变复数变化规则

变复数为:They are eating les.

句子变复数方法:

一、人称代词由单数变复数:

1 主格 I we ,you you ,he/she/it they .

2 宾格me us ,you you ,him/her/it them .

例1 She is a girl . They are girls .

例2 I like her. We like them.

二、指示代词由单数变复数:

this these , that those

例1 This is a book . These are(some)books .

例2 Is that a pen? Are those(any)pens?

三、反身代词:

第一人称 myself ourselves

第二人称 yourself yourselves

第三人称 himself themselves

( herself, itself )

例1 I am teaching myself computer.

We are teaching ourself computer.

例2 The child himself draws this picture.

The children themselves draw these pictures.

四、物主代词由单数变复数:

1 名词性物主代词:mine ours ,yours yours ,

his/hers/its theirs

2 形容词性物主代词:my our,your your ,

his/her/its their

例1 The book is mine. The books are ours.

例2 This is her pen. These are their pens.

五、一般情况下,形容词性物主代词在单数句变复数句时不变。

例1 This is my book . These are my books .

六、当句中形容词性物主代词与句中的主语一致时,形容词性物主代词应随主语人称的变化而变化, 仍要保持一致。

例1 He likes his bike. They like their bikes.

七、连系动词由单数变复数 :is/am are

例1 I am a teacher. We are(some) teachers.

八、a/an表示一个,只能用在单数名词前,当单数句变复数句时,一定要把a/an去掉,或改为some/any。

例1 This is a book . These are(some)books .

例2 Is that a pen? Are those(any)pens?

九、当名词作定语或在介词短语中作介词宾语充当除宾语以外的其它成分时, 该名词不变。

例1 He is a boy student .They are(some)boy students.

(man和woman)除外。

例2 She is a woman worker.

They are(some)women workers.

十、单数句变为复数句时,句式不能改变,即单数句是疑问句时,变为复数句时,仍然是疑问句。

例1 What’s this? What are these?

例2 She likes his bike. They like their bikes.

怎样判断英语句子中的单复数

注意man复数形式是 men, woman 是 women。

变复数后的句子应该是

1.Those are old men,

2.Those are chairs.

3.What are those in English?

4.These are my friends.

5.Those are not their bikes.

记住that 复数变those,this 变these,his /her / its 变their ,其他一般加S,特殊情况特殊对待,多注意下复数变换形式就好了。

动词在句子中怎样变复数

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).

there is a tree in front of my house怎样变成复数句子

第三人称单数的形式

动词:

1.一般加s.

2.以辅音加y,变y为ies.

3.以f、fe结尾,变f、fe为ves.

There is A goat in the garden如何变复数句子

There is a tree in front of my house.

在我的房子前面有一颗树 。

要把句子改变为复数时,首先把主语 a tree 变

成 复数形式 trees ,然后把be 动词的 is 改为

复数形式 are , 就行了 。

There are the trees in front of my house.

复数句子:There are goats in the garden.翻译:花园里有山羊。

解析:首先主格人称代词要变成相应的复数主格人称代词,看例句没有人称代词不用改,接着am,is 要变为are。看例句There is要把is变成are,继续不定冠词a, an要去掉,例句中有a,去掉。

继续普通单数名词要变为复数形式。例句中goat是单数名词变为复数goats,最后指示代词this, that 要变为these, those。看例句没有不用改,句子改复数完成。
