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】

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)
