四级英语语法知识点

初一英语语法大全知识点~

初一英语语法虽然是从简单的一些日常用语出发的，但语法中常会有一些知识点看起来很细小，容易被忽视，但这些知识点掌握不熟练，往往会造成一些语法应用上的错误。因此在学习初一英语语法时，要认真、细心，不要觉得一些地方不重要而得过且过。

下面从几个方面，总结出了初一英语语法，如果要复习英语句法的同学，可以参考一下，

一、初一英语语法——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）

2、代词

项目 人称代词 物主代词 指示代词 反身代词

he him his his himself
it it its its this that itself

3、动词
A） 第三人称单数
当动词是第三人称单数时，动词应该像名词的单数变动词那样加s，如下：

四）以o结尾加es。如：does, goes
五）特殊的有：are-is, have-has

一）一般在后加ing。如：spell-spelling, sing-singing, see-seeing, train-training, play-playing, hurry-hurrying, watch-watching, go-going, do-doing
二）以不发音e的结尾的去掉e再加ing。如：dance-dancing, wake-waking, take-taking, practice-practicing, write-writing, have-having

四）以ie结尾的变ie为y再加ing。如：tie-tying系 die-dying死 lie-lying 位于

4、形容词的级
我们在对两个或以上的人或物进行对比时，则要使用比较或最高级形式。构成如下：
