初一英语上册知识点梳理 篇一
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
复数 they them their theirs these those themselves
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:
一)一般在词后加s。如:comes, spells, waits, talks, sees, dances, trains
二)在x, sh, ch, s, tch后加es。如:watches, washes, wishes, finishes
三)1)以辅音字母加y结尾的变y为i再加es。如:study-studies, hurry-hurries, try-tries

四)以o结尾加es。如:does, goes
五)特殊的有:are-is, have-has
B) 现在分词
当我们说某人正在做什么事时,动词要使用分词形式,不能用原形,构成如下:
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
三)以重读闭音节结尾且一个元音字母+一个辅音字母(注意除开字母组合如show –showing, draw-drawing)要双写最后的辅音字母再加ing。如:put-putting, run-running, get-getting, let-letting, begin-beginning
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,则要使用比较或级形式。构成如下:
一) 一般在词后加er或est(如果是以e结尾则直接加r或st)。如:greater-greatest, shorter –shortest, taller –tallest, longer –longest, nicer- nicest, larger -largest
二)以重读闭音节结尾且1个元音字母+1个辅音字母(字母组合除外,如few-fewer fewest)结尾的双写结尾的辅音再加er /est。如:big-bigger biggest, red-redder reddest, hot-hotter hottest
三) 以辅音字母+y结尾的变y为i加er/est。如:happy-happier happiest, sorry-sorrier sorriest, friendly-friendlier friendliest(more friendly most friendly), busy-busier busiest, easy-easier easiest
四)特殊情况:(两好多坏,一少老远)
good/well - better best many/much - more most bad/ill – worse worst
little- less least old- older/elder oldest/eldest far- farther/further farthest/furthest

初一英语上册知识点 篇四
一、48个国际音标及26个英文字母的正确书写
要熟练掌握元音和辅音,5个元音字母(a, e, i, o, u),字母的正确占格及单词间距。
二、be动词的用法
be动词有三种变形,分别是:am, is, are。记忆口诀:
“我“用am, “你“用are, is用于“他、她、它“;单数全都用is,复数全部都用are。
三、人称及人称代词的不同形式(主格和宾格)
1、三种人称:第一人称(I, we),第二人称(you, you),第三人称(he, she, it, Maria)。
2、人称代词的主格,即人称代词位于句子主语位置时的形态:I, We, You, You, He, She, It, Maria。
3、人称代词的宾格,即人称代词位于句子宾语位置时的形态:me, us, you, you, him, her, it。
4、形容词性物主代词:my, our, your, your, his, her, its, their。
5、名词性物主代词:mine, ours, yours, yours, his, hers, its, theirs。
6、反身代词:myself, ourselves, yourself, yourselves, himself, herself, itself, themselves。
四、基数词(表示数量多少的词,大致相当于代数里的自然数)
zero, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three,twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, thirty, forty, fifty, sixty,seventy, eighty, ninety, one hundred,one hundred and one。
五、一般疑问句及特殊疑问句
1、一般疑问句:能用Yes或No来回答的问句。一般疑问句句尾读升调。
2、特殊疑问句:不能用Yes或No来回答的问句。特殊疑问句句尾读降调。
六、可数名词变复数
可数名词变复数时,有规则变化和不规则变化两种。
1、规则变化:
(1)一般情况直接在词尾加“-s “,如:cake-cakes, bag-bags, day-days, face-faces, orange-oranges等;
(2)以s, x, sh, ch结尾的词,要在词尾加“-es “,如:bus-buses, watch-watches, box-boxes等;
(3)以辅音字母加y结尾的词,变y为i再加“-es “,如:baby-babies, country-countries, family-families等;
(4)部分以f (e)结尾的词,变f (e)为“ves “,如:knife-knives, half-halves等;
(5)以o结尾的词,加“-s “或“-es “,如:zoo-zoos, photo-photos, tomato-tomatoes, potato-potatoes等。记忆口诀:除了“英雄“hero外,凡是能吃的,加“-es “,不能吃的加“-s “。
2、不规则变化:
(1)改变单数名词中的元音字母:man-men, woman-women, foot-feet, tooth-teeth等;
(2)单、复同形:sheep-sheep, Chinese-Chinese, Japanese-Japanese等;
(3)其他形式:mouse-mice, child-children等。
七、简单句的成分及主谓一致原则
最基本构成:主语+谓语+宾语,其中谓语由动词来充当。
主谓一致原则,就是句子的谓语要始终与主语保持数量上的一致性。当主语是第三人称单数(简称“三单“)时,谓语动词也要相应变成单数形式;当主语非“三单“时,谓语动词就用原形。实意动词变“三单“的规则如下:
(1)一般动词在词尾加“-s “,如:like-likes, tell-tells, play-plays等;
(2)以字母s, x,ch, sh结尾的动词加“-es “,如:guess-guesses, teach-teaches, watch-watches等;
(3)以o结尾的动词一般加“-es “,如:do-does, go-goes等;
(4)以辅音字母加y结尾的动词,先变y为i,再加“-而是“,如:fly-flies, carry-carries等;
(5)have的三单形式是has。
八、冠词的用法(名词前面必须要有冠词)
冠词分为定冠词(the)和不定冠词(a, an)两种。
1、定冠词the表示“特指“,可译为“这个“、“那个“、“这些“、“那些“。
2、不定冠词a, an用来表明(可数)名词的数量是“一个“。an用于以元音开头(注意不是以元音字母开头)的单词前,a则英语非元音开头的单词前。
3、不定冠词a, an与基数词one的区别是:不定冠词不是刻意强调“数量“,而基数词则强调“数量“。
九、助动词(do, does )的用法
只有实意动词作谓语时才涉及使用助动词。以like为例:
(1)当句子为肯定句时不涉及使用助动词,只涉及“主谓一致“原则。
eg : I like English a lot.
Michael likes Chinese food very much.
(2)当句子为否定句时,要根据主语的人称来决定使用相应的助动词:当主语为“三单“时,要使用does;当主语为“非三单“时,用助动词原形do。例如把下列句子变否定句:
Kangkang likes math.----Kangkang doesnt like math.
They like sports.------They dont like sports.
(3)当句子变疑问句时,同样要根据句子的主语来决定在句首使用Do或Does.例如下列句子变问句:
Michael likes Chinese Food.----Does Michael like Chinese food? Yes, he does./ No, he doesnt.
Jane and Helen like music.----Do Jand and Helen like music? Yes, they do./ No, they dont.
十、名词所有格
1、Kangkangs books;Tom and Helens desk; Anns and Marias bikes;
2、用of表示“。.。.。.的“,但要从of后往of前翻译:a book of mine(我的一本书)
3、have与of的区别:
have一般表示“主动拥有“,往往用于有生命的人或动物;无生命的物体一般不能“主动拥有“,表示所属关系时要用of。例如:
I have a new bike. She has two big eyes.
a door of the house

both表示“两者都。.。.。.“;all表示“三者及以上都。.。.。.“。
2、Unit 3--Unit 4
(1)speak的用法

I dont have any money.
Do you have any money?
(3)have a seat = take a seat(请随便坐)
(4)祈使句(表示命令或请求的句子)
祈使句一般都省略了主语You,所以其否定句直接用Dont开头。例如:
Dont go there!

What does sb. do?
What is sb.?
Whats sb.s job?
(6)work与job的区别:
work是未必有报酬的“工作“,例如homework, housework;而job则一定是有报酬的“工作“。

on the desk/ wall/ farm/ playground
(8)in hospital(住院);in the hospital(在医院里)
look after(照料/照顾/照看)

(10)“吃“一日三餐要用have:have breakfast/ lunch/ supper
have.。.for breakfast/ lunch/ supper

(11)try on这个词组可合可分:名词可以放在这个词组的中间或后面,但代词只能放在词组的中间。
(12)在口语中往往用take表示“买“。
(13)how many与how much的区别:
how many +可数名词;how much +不可数名词
(14)What do you think of.。.?是询问对方对某事物的看法;
How do you like.。.?是问对方对某事物喜欢的程度。
think about(考虑)
Thank you all the same. (即使对方没能帮上忙,也要礼貌道谢)
Thanks. = Thank you.(thank作为动词,不能单独使用。)
(15)one与it的区别:
当上下文说的是同一种类事物时,任意一个可以用one来代替;如果上下文所说的是同一个事物时则用it。例如:

Mike:Look, its over there.
(16)倒装句

Here it is.
(17)be free (有空/免费)

must则表示主观愿望
(20)fly a kite = fly kites
be free = have time
(21)句型“该干某事了。“:Its time to do sth. = Its time for sth.
例如:该吃午饭了。
Its time to have lunch. = Its time for lunch.
(22)时间的表述
当分针所指的时间大于0分、小于等于30分钟时,用“分钟“past“小时“。例如:
8:23--twenty-three past eight
当分针所指的时间大于30分钟、小于60分钟时,用“剩余的时间“to“下一个整点“。例如:
8:49--eleven to nine
当然,还可以直接按照小时、分钟去读出时间,例如:
8:23--eight twenty-three; 8:49--eight forty-nine
整点则在数词后加“-oclock“,例如:8:00--eight oclock
在钟点前介词要用at.
