//英语单复数的句子变换//

把单数的句子成复数的句子很简单：变法是把能变成复数的词变成复数，但a或an要把去掉。特殊疑问词、形容词、及地点通常不变。

Eg:把下列句子变成复数

1, I have a car ----we have cars

2, He is an American boy. ----They are American boys

3, It is a car ----They are cars

4,This is an eraser ----These are erasers

5,That is a backpsck -----Those are backpacks

6,I'm an English teather ------We are English teathers

7,It's a new shirt---- They are new shirts

8,He's a boy ----They are boys

9,She's a singer ------They are singers

10,What'sthis in English?---- What are these in English?

//英语名词的数语法//

名词有单数和复数两种形式

1、名词的单数：表示一个人或一个事物

2、名词的复数：表示一个人以上的人或事物

名词复数的变化规律如下：

1、多数情况下在名词后面加S，s 在清辅音后读【S】

2、以s,x,sh,ch为结尾的词在词尾加es, es读作【iz】

3、以f ,fe为结尾的词去掉f或fe加ves，ves读作【vz】

4、以辅音加y 结尾的词，变y为ies

5、以元音加y结尾的词，直接加s

6、不规则变化

Man-menwoman-women policeman-policemen

Policewoman-policewomen这种情况下a变成e

1、单复数同形

Chinese-chinese Japanese-japanese sheep -sheep deer -deer

2、 This 这个these这些(复数) that那个 those那些(复数) I我 we我们(复数) he他 she她 it它 they他、它、她们(复数) am ，is是 are(复数)
