单数句变复数句六绝招
单数句变复数句是七年级英语试题中的一个题类,小学英语一般很少涉猎,进入初中,有的同学在做类似题时往往丢三落四,容易出错。

只要注意下面的六要素,问题便迎刃而解:1.人称代词主格单数变成相应的人称代词主格复数,即I→we;you→you;she,he,it→they。

如:She is a girl.→They are girls.
2.am, is 变为are。

如:
I'm a student. →We are students.
3.不定冠词a, an 要去掉。

如:
He is a boy. →They are boys.
4.普通单数名词要变为复数形式。

如:
It is a cat. →They are cats.
5.指示代词this, that 变为these, those。

如:
This is a book.→These are books.
6.man, woman 作定语修饰可数名词时,要在"数"上与被修饰名词保持一致。

但其他名词修饰名词表示"性质"时,不作变化。

如:
He is a man doctor.→They are men doctors.
This is an apple tree.→They are apple trees.
※记住单数句变复数句的口诀。

单数句子变复数,变化规则要记住。

名词代词要变化,am, is 要变are。

this, that 该咋办,these, those 替代它。

he, she, it 要变啥,全部变they 就行了。

I要变we 别落下,名词后面把s/es加。

名前冠词去掉它,其余成分原样加。

但是,在英语中有些单数句不能变为复数句,如:Lily is fourteen.(莉莉十四岁。

)His name is Jim.(他的名字叫吉姆。

)等。

●上面练习做得还顺手吗?还是看看专家是如何解析吧!
【专家解析】单数句变复数句涉及名词和动词的人称和数,人称代词、物主代词、指示代词的人称和数的问题。

单数句变为复数句时,上述各类词都要做相应变化,其它词类不变。

当然,也有一些特殊的情况。

1. These are (some) chairs.
2. Are those (any) pencil-boxes?
■在把单数句子变为复数句子时,指示代词需要作相应的变化:
this→these, that→these。

第1、2小题即是如此。

3. They are (some) good boys.
4. Are they (any) rulers?
5. We are English teachers.
■在把单数句子变为复数句子时,人称代词需要作相应的变化:
主格:I→we, you→you, he/she/it→they
宾格:me→us, you→you, him/her/it→them。

第3、4、5小题即是如此。

6. These are our (my) new books.
7. Those blue erasers are ours.
■在把单数句子变为复数句子时,物主代词需要作相应的变化:
形容词性物主代词:my→our, your→your, his/her/its→their
名词性物主代词:mine→ours, yours→yours, his/her/its→theirs。

第6、7小题即是如此。

8. What are these in English?
9. We are (some) drivers.
■在把单数句子变为复数句子时,连系动词be需要作相应的变化:
(be)am/is→are。

第8、9小题即是如此。

10. They have (some) pencil sharpeners.
11. Are they (any) pears?
■a/an表示“一个”,只能用在单数可数名词之前,在把单数句子变为复数句子时,一定要
把a/an去掉,或改为some/any。

第10、11小题即是如此。

12. These are my pens.
13. They like their bikes.
■在把单数句子变为复数句子时,一般情况下,形容词性物主代词不需要改为复数形式。

第12小题即是如此;但是当句中形容词性物主代词与句中的主语一致时,该物主代词应随主语人称的改变而变化,仍要保持一致。

第13小题即是如此。

14. Are those (any) apple trees.
15. They are (some) men doctors.
■在把单数句子变为复数句子时,起修饰作用(作定语)的名词一般保持不变,只将其后的名词改为复数形式。

第14小题(如apple)即是如此;但是,若man或woman做定语修饰可数名词时,在整个句子变成复数的情况下也要变成men 或women。

第15小题即是如此。

16. What are your telephone numbers?
17. Where are your computers?
18. Are you in Class One?
■在把单数句子变为复数句子时,第二人称形容词性物主代词your与其人称代词you单复数同形,因此只需要改变其他部分的单复数形式即可。

如第16、17、18小题即是。

19. --Are those their brothers? --No, they aren’t.
20. --Are they our teachers? --Yes, they are.
■在把单数句子变为复数句子时,句式不能改变,即单数句子是疑问句,变为复数句子时仍然是疑问句。

第19、20小题即是。

21. We are at home.
22. They can have a look at these pictures.
■凡事都有特殊情况,在把单数句子变为复数句子时,一些固定短语(如at home,have a look 等)中的单数可数名词是不可以改变的,仍然保留原先的单数形式。

如第21小题中的home,第22小题中的look即是如此。
