初中英语语法大全

一、名词的数

我们知道名词可以分为可数名词和不可数名词，而不可数名词它没有复数形式，但可数名词却有单数和复数之分，复数的构成如下：

一）在后面加s。如：fathers, books, Americans, Germans, apples, bananas 二）x, sh, ch, s, tch后加es。如：boxes, glasses, dresses, watches, wishes, faxes 三）1）以辅音字母加y结尾的变y为i再加es 如：baby-babies, family-families, duty-duties, comedy-comedies, documentary-documentaries, story-stories

2）以元音字母加y结尾的直接加s。如：day-days, boy-boys, toy-toys, key-keys, ways 四）以o结尾加s（外来词）。如：radios, photos, 但如是辅音加o的加es：如: tomatoes西红柿, potatoes马铃薯

五）以f或fe结尾的变f为v再加es(s)。如：knife-knives, wife-wives, half-halves, shelf-shelves, leaf-leaves, yourself-yourselves

六）单复数相同（不变的）有：fish, sheep, deer鹿子, Chinese, Japanese 七）一般只有复数，没有单数的有：people,pants, shorts, shoes, glasses, gloves, clothes, socks

八）单词形式不变，既可以是单数也可以是复数的有：police警察局，警察, class班，同学, family家，家庭成员

九）合成的复数一般只加主要名词，多数为后一个单词。如：action movie-action movies, pen pal-pen pals; 但如果是由man或woman所组成的合成词的复数则同时为复数。如：man doctor-men doctors, woman teacher-women teachers

十）有的单复数意思不同。如：fish鱼 fishes鱼的种类, paper纸 papers报纸，卷子，论文, work工作 works作品，工厂, glass玻璃 glasses玻璃杯，眼镜, orange桔子水 oranges橙子, light光线 lights灯, people人 peoples民族, time时间 times时代, 次数, chicken 鸡肉 chickens 小鸡

十一） 单个字母的复数可以有两种形式直接加s或’s。如：Is (I’s), Ks (K’s)。但如是缩略词则只加s。如：IDs, VCDs, SARs

十二） 特殊形式的有：child-children, man-men, woman-women, foot-feet, mouse-mice, policeman-policemen, Englishman-Englishmen
