『壹』 七年級上冊英語的語法知識

初一上冊英語語法

1.there be 句型 「有」指 「某地有某物」形式 :there is, there are

例:There is some food in the fridge。冰箱里有一些食物。

There are many books on the desk. 桌上有許多書。

區分:there is 用於修飾單數名詞和不可數名詞 ,例如:a book , an egg, milk, ice-cream .......

there are 用來修飾可數名詞復數

如果要表達某處沒有某物 則要用there be 句型的否定形式,即在there be 後加not ,即 there be not

形式:there is not (there isn't) there are not (there aren't)

例: There isn't any milk in a glass。

There aren't any vegetables in the fridge.

若表示是否有,則要用 there be 句型的疑問句 即把be 提前 Be there 形式 Is there , Are there

例:Is there any milk in the glass?

Are there any vegetables in the fridge?

注意:這里涉及some any 的用法 some 用於肯定句中,any 用於否定句和疑問句中。但是在表示請求的

疑問句中,是想要得到肯定答復的,要用some。例:Would you like some milk?

對於there be 疑問句的回答:肯定:Yes,there is\are. No,there isn't\aren't.

2.have\has got 有 指某人有某物

例:I have a dog.我有一隻狗。

He has a sister and a brother.他有一個姐姐和一個弟弟。

區分 :have\ has: have用來修飾第一人稱和第二人稱和第三人稱復數(I ,we ,they) has用來修飾第三

人稱單數(she, he , it )

若表示某人沒有某物,則要用否定形式,即在have\has got 後加not 即have not (haven't)got ,has not

(hasn't)got.

例:I haven't got a sister but i have a brother.

She hasn't got bright eyes and long hairs.

某人是否有某物則要用have\has got的疑問形式,Have\Has +sb.\sth. + got

Have they got a picnic at weekends?

Has the dog got a host family?

回答:肯定:Yes, i \we \they have. Yes , she\ he \ it has.

否定:No , i \ we \ they haven't. No, she \he \it hasn't.

注意:there be 和 have got 的區別 兩者雖都指"有",但側重點不同。

例:《1》There are some food in the fridge.

<2>The fridge has got some food.

雖然都是「冰箱里有食物」但(1)句側重於食物,(2)句側重於冰箱。

3.be(am is are)

用法:我用am 你用are is連著她他它,單數用is,復數用are

例:I am a stident. She is a beutiful girl. He is a child. It is a dog.

You are my teacher. They are my friends, The boys all are England.

be 的否定形式 直接加not 即 am not, are not , is not.

例:I am not an English. I am Chinese.

She isn't kind. They aren't my friends.

疑問形式把be提前 即 be+ 主語......?

例:Is he your father?

Are they going to have a party?

回答:肯定:Yes, I am. Yes,she \ he \it is. Yes , you \ we \ they are.

否定: No, I am not. No, she \ he \ it isn't. No , you \ we \ they aren't.

be的句式, 所用情況:

1》be + 形容詞(adj.). 例:I am very happy.

2> be+ 名詞(n.) 例:He is a boy.

3> be + 介詞短語 例:She is in the school.

4> be+形容詞短語例: He is only 11 years old.

5> be+ 副詞 例:Class is over.

4. 情態動詞 can

can 可以 能夠,表示某人能做某事 用法:can+v.原 不能做某事,則用can 的否定形式:

cannot (can't)+v.原

can沒有人稱和數的變化,因此誰能(不能)做某事都能用can

若表示某人是否能做某事 則要用can 的疑問形式,即can+sb.……?

例:I can speak Chinese. I can't speak English. Can you speak English?

He can swim but he can't play football.

Can she play the piano?

疑問句回答 :肯定:Yes, I \she \ you \ he \it \they \ we can.

否定:No, I \ she \ he \it \ you \ we \ they can't.

注意:can 表示「能力」時,指現在的能力,並不指過去或將來的能力。

5 . 情態動詞would 想 主要用於 would you like to ...句型中,表示邀請。

例:Would you like to go to school with me ?

回答一般有兩種形式:1 表示願意:I' like \ love to. 2 拒絕:Sorry, 原因。

注意:would like to 本身並不表示邀請, 而是想要。例:I would like to some books.

另外,表示邀請還能說:Let's...... Shall we...... What \ How about.......

還要注意邀請時詢問信息的表達方式:1)詢問時間:When is... 2) 詢問地點: Where is....

6 行為動詞的一般現在時

用法:

1.如果表示某人經常性或習慣性做某事,則要用行為動詞的一般現在時

He goes to school every day.

They eat dinner in the evening.

2.若表示某人現在的動態,也可用一般現在時。

I know him very well. 我和他很熟。

He likes English very much. 他非常喜歡英語。

若表示否定意義,若主語是第一人稱或第二人稱或第三人稱復數,只要在謂語動詞後加not,即do not

(don't) ,若主語是第三人稱單數,則要在謂語動詞後加does not (doesn't)

例:I don't go to school every day.

She doesn't goes to the shop every day.

You don' t sing vell well.

若表示是否經常做某事 則要用疑問意義,將do \ does 提前即可

例:Do you write a composition every day? 你每天寫一篇作文嗎?

Does it smell good? 它聞起來很香嗎?

注意:行為動詞的一般現在時中涉及了頻度副詞,用法:用於行為動詞之前,be動詞之後

常見的頻度副詞有:often ,always , usually , never ,seldom ,sometimes等

7.變法總結

『叄』 初一英語上冊,每個單元知識語法總結點

初一英語語法總結
一、 詞法 1、名詞A)、名詞的數
我們知道名詞可以分為可數名詞和不可數名詞,而不可數名詞它沒有復數形式,但可數名詞卻有單數和復數之分,復數的構成如下:
一)在後面加s。如:fathers, books, Americans, Germans, apples, bananas
二)x, sh, ch, s, tch後加es。如:boxes, glasses, dresses, watches, wishes, faxes
三)1)以輔音字母加y結尾的變y為i再加es 如:baby-babies, family-families, ty-ties, comedy-comedies, documentary-documentaries, story-stories
2)以母音字母加y結尾的直接加s。如:day-days, boy-boys, toy-toys, key-keys, ways

『肆』 人教版英語七年級上冊主要學習哪些語法

1. 名詞所有格
名詞如要表示與後面名詞的所有關系,通常用名詞所有格的形式,意為"……的"。一般有以下幾種形式:

(1). 一般情況下在詞尾加"'s"。例如:
Kate's father Kate的爸爸
my mother's friend 我媽媽的朋友

(2). 如果復數名詞以s結尾,只加"'"。例如:
Teachers' Day 教師節
The boys' game 男孩們的游戲

(3). 如果復數名詞不以s結尾,仍加"'s"。例如:
Children's Day 兒童節
Women's Day 婦女節

(4). 表示兩個或幾個共有時,所有格應加在後一個名詞上。例如:
Lucy and Lily's room Lucy 和Lily的房間
Kate and Jim's father Kate 和Jim的爸爸

動物和無生命事物的名詞的所有格一般不在詞尾加"'s",而常常用介詞of的短語來表示。
a map of China 一幅中國地圖
the name of her cat 她的貓的名字
a picture of my family 我的家庭的一張照片
the door of the bedroom 卧室的門

2. 祈使句
祈使句主要用來表示說話人的請求、命令、建議、叮囑等意圖。祈使句一般不用主語,讀時用降調。為使語氣委婉、禮貌,常在句首或句尾加please 。在句尾時,please前多用逗號。

(1). 祈使句肯定形式的謂語動詞一律用動詞原形。
Go and see. 去看看。
Come in, please. 請進。

(2). 祈使句的否定形式常用don't於句首。
Don't look at your books. 不要看書。
Don't play on the road. 不要在馬路上玩。

3. There be 的句子結構

There be是一個"存在"句型,表示"有"的意思,
肯定句的形式為:There be + 名詞(單數或復數)+地點狀語或時間狀語。
be動詞單復數的確定,看be後邊第一個名詞,當所接主語為單數或不可數名詞時,be動詞形式為is;當所接主語為復數名詞時,be動詞為are;當be動詞後接兩個以上主語時,be動詞與最臨近主語保持數上的一致。意思為"某地有某人或某物"。如:
There is an eraser and two pens on the desk. 桌子上有一塊橡皮和兩支鋼筆。
There are two pens and an eraser on the desk. 桌上有兩支鋼筆和一塊橡皮。

(1)there be的否定句,即在be的後面加上not。
否定形式為:There be + not + (any) + 名詞+地點狀語。
There is not any cat in the room. 房間里沒貓。
There aren't any books on the desk. 桌子上沒書。

(2)there be句型的疑問句就是將be提到句首:Be there + (any) +名詞+地點狀語?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? 畫上有一隻狗嗎?
---Yes, there is. 有。
---Are there any boats in the river? 河裡有船嗎?
---No, there aren't. 沒有。

(3)特殊疑問句:How many . . . are there (+地點狀語)?"某地有多少人或物?"回答用There be . . .
There's one. / There are two / three / some . . .
有時直接就用數字來回答。One. / Two . . .
---How many students are there in the classroom? 教室里有多少學生?
---There's only one. / There are nine. 只有一個。/有九個。

(4)如果名詞是不可數名詞,用:How much + 不可數名詞 + is there + 地點狀語?
How much water is there in the cup? 杯中有多少水?
How much food is there in the bowl? 碗里有多少食物?

『柒』 初中七年級英語上冊語法

七年級上冊英語語法

(就10點,耐心看)

1.動詞be(is,am,are)的用法
我(I)用am, 你(you)用are,is跟著他(he),她(she),它(it)。單數名詞用is,復數名詞全用are。變否定,更容易,be後not加上去。變疑問,往前提,句末問號莫丟棄。還有一條須注意,句首大寫莫忘記。

2.this,that和it用法
(1)this和that是指示代詞,it是人稱代詞。
(2)距離說話人近的人或物用this, 距離說話人遠的人或物用that。如:
This is a flower. 這是一朵花。(近處)
That is a tree. 那是一棵樹。(遠處)
(3)放在一起的兩樣東西,先說this, 後說that。如:
This is a pen. That is a pencil. 這是一支鋼筆。那是一支鉛筆。
(4)向別人介紹某人時說This is…, 不說That is…。如:
This is Helen. Helen, this is Tom. 這是海倫,海倫,這是湯姆。
(5)This is 不能縮寫, 而That is可以縮寫。如:
This is a bike. That』s a car. 這是一輛自行車。那是一輛轎車。
(6)打電話時,介紹自己用this, 詢問對方用that。如:
—Hello! Is that Miss Green? 喂,是格林小姐嗎?
—Yes, this is. Who』s that? 是的,我是,你是誰?
注意:雖然漢語中使用「我」和「你」,但英語中打電話時絕不可以說:I am…, Are you…?/Who are you?

(7)在回答this或that作主語的疑問句時, 要用it代替this或that。如:
①—Is this a notebook? 這是筆記本嗎?
—Yes, it is. 是的,它是。
②—What』s that? 那是什麼?
—It』s a kite. 是只風箏。

3.these和those用法
this, that, these和those是指示代詞,these是this的復數形式,指時間,距離較近的或下面要提到的人或事;those是that的復數形式,指時間、距離較遠或前面已經提到過的人或事物。
①This is my bed. That is Lily』s bed. 這是我的床。那是莉莉的床。
②These pictures are good. 那些畫很好。
③ Are those apple trees? 那些是蘋果樹嗎?
在回答主語是these或those的疑問句時,通常用they代替these或those以避免重復。如:
④Are these/those your apples? 這些(那些)是你的蘋果嗎?
Yes, they are. 是的,他們是。

4.名詞+』s所有格
單數名詞後直接加 「 』s 」:
Jim』s coat 吉姆的外套 Jeff』s mother傑夫的媽媽
以s結尾的復數名詞,只加「』」
Teachers』 Day教師節 the twins』 books雙胞胎的書
不以s結尾的不規則的名詞復數,加「 』s 」
Children』s Day 兒童節 men』s shoes男式鞋
表示兩者共同擁有時,只在最後一個名詞後加』s
Lucy and Lily』s mother 露茜和莉莉的媽媽(共同的媽媽,一個媽媽)
表示兩者各自擁有時,要在每個名詞後加』s
Lucy』s and Kate』s rooms 露茜和凱特的房間(各自的房間,兩間房子)

5.There be句型
(1)There be句型主要用以表達「某處(某時)有某人(某物)。」其基本結構為「There be+某物(某人)+某地(某時)」其中there是引導詞,沒有詞義;主語是be後面的名詞, be是謂語動詞,在一般現在時中be只用is和are兩種形式。下面這首歌訣可幫你巧記there be句型結構:
There be放句首,主語跟在後。地、時放句末,強調置前頭。如:
There is a book on the desk.
有時為了強調地點,也可把介詞短語放在句首。如:
On the desk there is a book.
(2)There be句型中的be動詞如何確定呢?請先看看下面這首歌訣:
Be動詞,有三個,am,is還有are。「There be」真特別,不留am只留倆,那就是is還有are。要用is還是are,須看其後的名詞是單數還是復數。若是單數或不可數名詞用is,否則就用are。如:
①There is a tree behind the house.
②There is some water(水)in the bottle(瓶子).
③There are some pears in the box.
(3)注意:如果「be」後的主語是由and連接的兩個或兩個以上的名詞,那麼be的形式要遵循「遠親不如近鄰」的原則。也就是說,「be」的形式是由與它最近的那個名詞來確定的。若那個名詞是單數或不可數名詞要用is,是復數就用are。如:
①There is a book and some pens on the floor.
②There are some pens and a book on the floor.

6.like一詞的用法
like用作及物動詞,譯為「喜歡」。
(1)後接名詞或代詞,表示喜歡某人或某物。如:
I like the baby very much. 我非常喜歡這個小孩。
(2)後接動名詞(v. -ing),表示「喜歡做某事」,著重於習慣、愛好。如:
Tom likes playing football. 湯姆喜歡踢足球。
(3)後接動詞不定式(to do ),表示「偶爾地喜歡做某事」,著重於某次具體的行為。如:
I like reading, but I like to watch TV this evening. 我喜歡讀書,但我今晚想看電視。

7.句子單數變復數,注意以下五要素
(1)主格人稱代詞要變成相應的復數主格人稱代詞,即I→we, you→you,she,he,it→ they。
如:She is a girl. →They are girls.
(2)am,is要變為are。如:
I』m a student. →We are students.
(3)不定冠詞a,an要去掉。如:
He is a boy. →They are boys.
(4)普通單數名詞要變為復數形式。如:
It is an apple. →They are apples.
(5)指示代詞this,that要變為these,those。如:
This is a box. →These are boxes.

8.英語日期的表示法
英語中月份和星期名稱都是專有名詞,它們的首字母必須大寫,並且前面無需用冠詞。
用英語表示日期,其順序為月+日+年,日和年之間需用逗號隔開。如:August 2nd,2003(2003年8月2日)。也可以用日+月+年來表示。如:10th May,2003(2003年5月10日)英語日期前介詞的使用:若指在哪一年或哪一月,則用介詞in,若具體到某一天,則需用介詞on。

9.時間的表達法
(1) 直讀式,即直接讀出時間數字
7: 05 seven five 8:16 eight sixteen
(2) 過、差式,即幾點差幾分,幾點過幾分。(以30分為分界線)
1:25 twenty-five past one 2:30 half past two
3:43 seventeen to four 4:38 twenty-two to five
(3)12小時制
6:00 a.m. 上午6點 8:20 p.m. 下午8點20分
(4)24小時制
13:00 13點鍾 22:15 22點15分
(5)15分可用quarter
4:15 a quarter past four 5:45 a quarter to six
(6)時間前通常用at.
at 5 o』clock at 7:30 p.m.

10. want用法
(1)想干什麼用want to do sth
They want to join the sports club. 他們想加入運動俱樂部。
(2)第三人稱單數作主語,want要作變化
①He wants to play basketball.
②Li Xia wants to play the piano.
(3)變疑問句,否定句要藉助助動詞do或does.
①-Do you want to play soccer ball ? -Yes , I do . / No , I don』t.
②-Does he want to go home by bus ? -Yes , he does . / No , he doesn』t
