在英语里面怎样把单数形式的句子改为复数形式

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).

这个主语变化谓语跟着变化就可以了。举个例子 ：

She is a teacher .复数就是： We are teachers.

Liming goes to school by bike .

复数： They go to school by bike.
