人教版七年級英語知識點
㈠ 初中英語七年級上冊(人教版)知識點歸納
其實七年級的也算是很基礎的,小學時候基本都學過了,差不多像是復習和鞏固吧,內容還是比較簡單的,現在我總結一下大致內容吧:
一、48個國際音標及26個英文字母的正確書寫
要熟練掌握母音和輔音,5個母音字母(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用於「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,即人稱代詞位於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,即人稱代詞位於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,大致相當於代數里的自然數)
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)改變單數名詞中的母音字母: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用於以母音開頭(注意不是以母音字母開頭)的單詞前,a則英語非母音開頭的單詞前.
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 doesn't like math.
They like sports.------They don't 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 doesn't.
Jane and Helen like music.----Do Jand and Helen like music? Yes, they do./ No, they don't.
十、名詞所有格
1、Kangkang's books;Tom and Helen's desk; Ann's and Maria's bikes;
2、用of表示「.的」,但要從of後往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」,往往用於有生命的人或動物;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、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.
Hi! Hello!
How do you do?
2)道別用語:
Nice/ Glad to meet/ see you.(meet用於初次見面,see用於熟人間)
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I'm sorry.的區別:
Excuse me.是要引起對方的注意,而I'm sorry.則是向對方道歉.
5)片語be from = come from
in English
5)當問句中問到this/ that時,回答要用it;問到these/ those時,要用they來回答. 例如: What's this in English?----It's an eraser.
What are those?----They are books.
6)對Thanks.的回答:That's OK./ You're welcome./ My pleasur.
7)look the same = have the same looks
give sth. to sb. = give sb. sth.
be like = look like
in the tree/ on the tree (樹上結的、長出來的用on,否則用in)
in red(穿著紅色的衣服)
in the desk(在空間范圍之內)
in English(用英語)
help sb. do sth.
8)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.
speak後面除了能接「語言」外,不能直接接東西,後面加了to則表示「對.說」.
help sb. with sth.(幫助某人做/補習.)
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用於肯定句,否定、疑問變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(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Don't開頭.例如:
Don't go there!
5)問職業:
What does sb. do?
What is sb.?
What's 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?」
What about (doing) sth.? (英式英語)
How about (doing) sth.? (美式英語)
Why don't 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
take one's order
be kind to sb.
11)try on這個片語可合可分:名詞可以放在這個片語的中間或後面,但代詞只能放在片語的中間.
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, it's over there.
16)倒裝句
Here you are.
Here it is.
17)be free (有空/免費)
forget to do sth.(忘了去做某事)
forget doing sth.(忘了做過某事)
What's up? = What's wrong with...? = What's 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 則表示主觀願望
20)fly a kite = fly kites
be free = have time
21)時間的表述
當分針所指的時間大於0分、小於等於30分鍾時,用「分鍾」past「小時」.例如:
8:23——twenty-three past eight
當分針所指的時間大於30分鍾、小於60分鍾時,用「剩餘的時間」to「下一個整點」.例如:
8:49——eleven to nine
當然,還可以直接按照小時、分鍾去讀出時間,例如:
8:23——eight twenty-three; 8:49——eight forty-nine
整點則在數詞後加「-o'clock」,例如:8:00——eight o'clock
在鍾點前介詞要用at.
22)句型「該干某事了.」:It's time to do sth. = It's time for sth.
例如:該吃午飯了.
It's time to have lunch. = It's time for lunch.
