小学五年级英语下册语法

一、词语

1、名词

这里强调两点：不可数名词都默认为单数，所以总是用is 名词复数如何加后缀：各种不同情况变化方法例词

一般情况: 1)直接加-s

book-books bag-bags cat-cats bed-beds 以s. x. sh. ch

2)结尾加-es

bus-buses box-boxes brush-brushes

watch-watches peach—peaches glass--glasses

3)以“辅音字母+y”结尾变y为i, 再加-es

family-families study--studies

4)以“f或fe”结尾 ,变f或fe为v，再加-es

knife-knives

不规则名词复数

man-men woman-women policeman-policemen policewoman-police women mouse-mice foot-feet child-children fish-fish Chinese-C hinese
