初一英语上册知识点汇编(一)

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 doesn't like math.

They like sports.------They don't 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 doesn't.

Jane and Helen like music.----Do Jand and Helen like music? Yes, they do./ No, they don't.

十、名词所有格

1、Kangkang's books;Tom and Helen's desk; Ann's and Maria's 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

(1)问候语:

(2)道别用语:

Nice/ Glad to meet/ see you.(meet用于初次见面,see用于熟人间)

Nice to meet/ see you, too.

Goodbye. Byebye. Bye. See you (later/ tomorrow/ next time)! So long! Good night!

(3)介绍人或者物的句型:This is...

(4)Excuse me.与I'm sorry.的区别:

Excuse me.是要引起对方的注意,而I'm sorry.则是向对方道歉。

(5)词组be from = come from

(6)当问句中问到this/ that时,回答要用it;问到these/ those时,要用they来回答。 例如: What's this in English?----It's an eraser.

What are those?----They are books.

(7)对Thanks.的回答:That's OK./ You're welcome./ My pleasur.

(8)look the same = have the same looks

in the tree/ on the tree (树上结的、长出来的用on,否则用in)

in the desk(在空间范围之内)

in English(用英语)

help sb. do sth.

(9)both与all的区别:

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

speak与say不同:speak表示"说"的动作,不表示"说"的内容;say则表示"说"的内容。

speak后面除了能接"语言"外,不能直接接东西,后面加了to则表示"对......说"。

help sb. with sth.(帮助某人做/补习......)

want to do sth.(想要做某事)

would like to do sth.

not...at all(一点都不);Not at all.(没关系/别介意)

like...a lot = like...very much

(2)some和any的区别:

口诀:some用于肯定句,否定、疑问变any。例如:

I have some money.

I don't 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)
