初一英语语法总结
1. 名词所有格
　　初一英语语法名词所有格:名词如要表示与后面名词的所有关系,通常用名词所有格的形式,意为"……的".一般有以下几种形式：
（1）. 一般情况下在词尾加"'s".例如：
Kate's father Kate的爸爸
（2）. 如果复数名词以s结尾,只加"'".例如：
Teachers' Day 教师节
（3）. 如果复数名词不以s结尾,仍加"'s".例如：
Children's Day 儿童节
（4）. 表示两个或几个共有时,所有格应加在后一个名词上.例如：
Lucy and Lily's room Lucy 和Lily的房间
初一英语语法中,动物和无生命事物的名词的所有格一般不在词尾加"'s",而常常用介词of的短语来表示.
a map of China 一幅中国地图
the name of her cat 她的猫的名字
2. 祈使句
　　初一英语语法的句式——祈使句主要用来表示说话人的请求、命令、建议、叮嘱等意图.祈使句一般不用主语,读时用降调.为使语气委婉、礼貌,常在句首或句尾加please .在句尾时,please前多用逗号.
（1）. 祈使句肯定形式的谓语动词一律用动词原形.
Go and see. 去看看.
（2）. 祈使句的否定形式常用don't于句首.
Don't look at your books. 不要看书.
3. There be 的句子结构
　　初一英语语法另一个重点就是There be句型,There be是一个"存在"句型,表示"有"的意思,
肯定句的形式为：There be + 名词（单数或复数）+地点状语或时间状语.
be动词单复数的确定,看be后边第一个名词,当所接主语为单数或不可数名词时,be动词形式为is；当所接主语为复数名词时,be动词为are；当be动词后接两个以上主语时,be动词与最临近主语保持数上的一致.意思为"某地有某人或某物".如：
There is an eraser and two pens on the desk. 桌子上有一块橡皮和两支钢笔.
（1）there be的否定句,即在be的后面加上not.
否定形式为：There be + not + (any) + 名词+地点状语.
There is not any cat in the room. 房间里没猫.
（2）there be句型的疑问句就是将be提到句首：Be there + (any) +名词+地点状语?肯定回答：Yes, there is / are. 否定回答：No, there isn't / aren't.
---Is there a dog in the picture? 画上有一只狗吗?
---Yes, there is. 有.
（3）特殊疑问句：How many . . . are there (+地点状语)?"某地有多少人或物?"回答用There be . . . There's one. / There are two / three / some . . .
有时直接就用数字来回答.One. / Two . . .
---How many students are there in the classroom? 教室里有多少学生?
---There's only one. / There are nine. 只有一个./有九个.
（4）如果名词是不可数名词,用：How much + 不可数名词 + is there + 地点状语?
How much water is there in the cup? 杯中有多少水?
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）

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：
