初一英語上冊知識點
在年少學習的日子里,相信大家一定都接觸過知識點吧!知識點在教育實踐中,是指對某一個知識的泛稱。你知道哪些知識點是真正對我們有幫助的嗎?以下是小編為大家收集的初一英語上冊知識點,歡迎大家分享。
初一英語上冊知識點 1
一、48個國際音標及26個英文字母的正確書寫
要熟練掌握元音和輔音,5個元音字母(a, e, i, o, u),字母的正確占格及單詞間距。
二、be動詞的用法
be動詞有三種變形,分別是:am, is, are。記憶口訣:
“我“用am, “你“用are, is用于“他、她、它“;單數全都用is,復數全部都用are。
三、人稱及人稱代詞的不同形式(主格和賓格)
1、三種人稱:第一人稱(I, we),第二人稱(you, you),第三人稱(he, she, it, Maria)。
2、人稱代詞的主格,即人稱代詞位于句子主語位置時的形態:I, We, You, You, He, She, It, Maria。
3、人稱代詞的賓格,即人稱代詞位于句子賓語位置時的形態:me, us, you, you, him, her, it。
4、形容詞性物主代詞:my, our, your, your, his, her, its, their。
5、名詞性物主代詞:mine, ours, yours, yours, his, hers, its, theirs。
6、反身代詞:myself, ourselves, yourself, yourselves, himself, herself, itself, themselves。
四、基數詞(表示數量多少的詞,大致相當于代數里的自然數)
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、一般疑問句及特殊疑問句
1、一般疑問句:能用Yes或No來回答的問句。一般疑問句句尾讀升調。
2、特殊疑問句:不能用Yes或No來回答的問句。特殊疑問句句尾讀降調。
六、可數名詞變復數
可數名詞變復數時,有規則變化和不規則變化兩種。
1、規則變化:
(1)一般情況直接在詞尾加“-s “,如:cake-cakes, bag-bags, day-days, face-faces, orange-oranges等;
(2)以s, x, sh, ch結尾的詞,要在詞尾加“-es “,如:bus-buses, watch-watches, box-boxes等;
(3)以輔音字母加y結尾的詞,變y為i再加“-es “,如:baby-babies, country-countries, family-families等;
(4)部分以f (e)結尾的詞,變f (e)為“ves “,如:knife-knives, half-halves等;
(5)以o結尾的詞,加“-s “或“-es “,如:zoo-zoos, photo-photos, tomato-tomatoes, potato-potatoes等。記憶口訣:除了“英雄“hero外,凡是能吃的,加“-es “,不能吃的加“-s “。
2、不規則變化:
(1)改變單數名詞中的元音字母:man-men, woman-women, foot-feet, tooth-teeth等;
(2)單、復同形:sheep-sheep, Chinese-Chinese, Japanese-Japanese等;
(3)其他形式:mouse-mice, child-children等。
七、簡單句的成分及主謂一致原則
最基本構成:主語+謂語+賓語,其中謂語由動詞來充當。
主謂一致原則,就是句子的謂語要始終與主語保持數量上的一致性。當主語是第三人稱單數(簡稱“三單“)時,謂語動詞也要相應變成單數形式;當主語非“三單“時,謂語動詞就用原形。實意動詞變“三單“的規則如下:
(1)一般動詞在詞尾加“-s “,如:like-likes, tell-tells, play-plays等;
(2)以字母s, x,ch, sh結尾的動詞加“-es “,如:guess-guesses, teach-teaches, watch-watches等;
(3)以o結尾的動詞一般加“-es “,如:do-does, go-goes等;
(4)以輔音字母加y結尾的動詞,先變y為i,再加“-而是“,如:fly-flies, carry-carries等;
(5)have的三單形式是has。
八、冠詞的用法(名詞前面必須要有冠詞)
冠詞分為定冠詞(the)和不定冠詞(a, an)兩種。
1、定冠詞the表示“特指“,可譯為“這個“、“那個“、“這些“、“那些“。
2、不定冠詞a, an用來表明(可數)名詞的數量是“一個“。an用于以元音開頭(注意不是以元音字母開頭)的單詞前,a則英語非元音開頭的單詞前。
3、不定冠詞a, an與基數詞one的區別是:不定冠詞不是刻意強調“數量“,而基數詞則強調“數量“。
九、助動詞(do, does )的用法
只有實意動詞作謂語時才涉及使用助動詞。以like為例:
(1)當句子為肯定句時不涉及使用助動詞,只涉及“主謂一致“原則。
eg : I like English a lot.
Michael likes Chinese food very much.
(2)當句子為否定句時,要根據主語的人稱來決定使用相應的助動詞:當主語為“三單“時,要使用does;當主語為“非三單“時,用助動詞原形do。例如把下列句子變否定句:
Kangkang likes math.----Kangkang doesnt like math.
They like sports.------They dont like sports.
(3)當句子變疑問句時,同樣要根據句子的主語來決定在句首使用Do或Does.例如下列句子變問句:
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、名詞所有格
1、Kangkangs books;Tom and Helens desk; Anns and Marias bikes;
2、用of表示“......的“,但要從of后往of前翻譯:a book of mine(我的一本書)
3、have與of的區別:
have一般表示“主動擁有“,往往用于有生命的人或動物;無生命的物體一般不能“主動擁有“,表示所屬關系時要用of。例如:
I have a new bike. She has two big eyes.
a door of the house
十一、初一英語上冊知識點之課本中的知識點
1、Unit 1 --Unit 2
(1)問候語:
Good morning/ afternoon/ evening.
How are you?---Just OK, thank you. How are you?---Not bad, thanks.

Nice to meet/ see you, too.
Goodbye. Byebye. Bye. See you (later/ tomorrow/ next time)! So long! Good night!
(3)介紹人或者物的'句型:This is...
(4)Excuse me.與Im sorry.的區別:
Excuse me.是要引起對方的注意,而Im sorry.則是向對方道歉。
(5)詞組be from = come from

(9)both與all的區別:
both表示“兩者都......“;all表示“三者及以上都......“。
2、Unit 3--Unit 4
(1)speak的用法
speak與say不同:speak表示“說“的動作,不表示“說“的內容;say則表示“說“的內容。

help sb. with sth.(幫助某人做/補x.)
want to do sth.(想要做某事)
would like to do sth.
not...at all(一點都不);Not at all.(沒關系/別介意)
like...a lot = like...very much
(2)some和any的區別:
口訣:some用于肯定句,否定、疑問變any。例如:
I have some money.
I dont have any money.
Do you have any money?
(3)have a seat = take a seat(請隨便坐)
(4)祈使句(表示命令或請求的句子)
祈使句一般都省略了主語You,所以其否定句直接用Dont開頭。例如:
Dont go there!
(5)問職業:
What does sb. do?
What is sb.?
Whats sb.s job?
(6)work與job的區別:
work是未必有報酬的“工作“,例如homework, housework;而job則一定是有報酬的“工作“。
(7)on指在物體的表面,不論這個面是否水平的,例如:
on the desk/ wall/ farm/ playground
(8)in hospital(住院);in the hospital(在醫院里)
look after(照料/照顧/照看)
help oneself(請自便/隨便吃)
(9)表示“建議“的句型:“做某事如何?“

Why dont you do sth.? = Why not do sth.?
(10)“吃“一日三餐要用have:have breakfast/ lunch/ supper
have...for breakfast/ lunch/ supper

(11)try on這個詞組可合可分:名詞可以放在這個詞組的中間或后面,但代詞只能放在詞組的中間。
(12)在口語中往往用take表示“買“。
(13)how many與how much的區別:
how many +可數名詞;how much +不可數名詞
(14)What do you think of...?是詢問對方對某事物的看法;
How do you like...?是問對方對某事物喜歡的程度。
think about(考慮)
Thank you all the same. (即使對方沒能幫上忙,也要禮貌道謝)
Thanks. = Thank you.(thank作為動詞,不能單獨使用。)
(15)one與it的區別:
當上下文說的是同一種類事物時,任意一個可以用one來代替;如果上下文所說的是同一個事物時則用it。例如:
Ann:I have a yellow bag.
Jane:I have a green one.
Tom:Hey, Mike. Where is your bike?
Mike:Look, its over there.
(16)倒裝句
Here you are.
Here it is.

forget to do sth.(忘了去做某事)
forget doing sth.(忘了做過某事)
Whats up? = Whats wrong with...? = Whats the matter with...?
(18)go + v.-ing結構的含義:為了實現某目的才去的。例如:
go fishing/ boating/ swimming/ shopping等
(19)have to do sth.(非主觀因素,強調客觀因素,“不得不去做某事“)
must則表示主觀愿望
(20)fly a kite = fly kites
be free = have time
(21)句型“該干某事了。“:Its time to do sth. = Its time for sth.
例如:該吃午飯了.
Its time to have lunch. = Its time for lunch.
(22)時間的表述
當分針所指的時間大于0分、小于等于30分鐘時,用“分鐘“past“小時“。例如:
8:23--twenty-three past eight
當分針所指的時間大于30分鐘、小于60分鐘時,用“剩余的時間“to“下一個整點“。例如:
8:49--eleven to nine
當然,還可以直接按照小時、分鐘去讀出時間,例如:
8:23--eight twenty-three; 8:49--eight forty-nine
整點則在數詞后加“-oclock“,例如:8:00--eight oclock
在鐘點前介詞要用at.
