初一英语语法总结(人教版)
一、词法
1、名词
A)、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
B)名词的格
当我们要表示某人的什么东西或人时,我们就要使用所有格形式。构成如下:
一)单数在后面加’s。如:brother’s, Mike’s, teacher’s
二)复数以s结尾的直接在s后加’,如果不是以s结尾的与单数一样处理。如:Teachers’ Day教师节, classmates’; Children’s Day六一节, Women’s Day三八节
三)由and并列的名词所有时,如果是共同所有同一人或物时,只加最后一个’s,但分别拥有时却分别按单数形式处理。如:Mike and Ben’s room迈克和本的房间(共住一间),Mike’s and Ben’s rooms迈克和本的房间(各自的房间)
