『壹』 七年级上册英语的语法知识

初一上册英语语法

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. 桌上有许多书。

区分:there is 用于修饰单数名词和不可数名词 ,例如:a book , an egg, milk, ice-cream .......

there are 用来修饰可数名词复数

如果要表达某处没有某物 则要用there be 句型的否定形式,即在there be 后加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,则要用 there be 句型的疑问句 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:这里涉及some any 的用法 some 用于肯定句中,any 用于否定句和疑问句中。但是在表示请求的

疑问句中,是想要得到肯定答复的,要用some。例:Would you like some milk?

对于there be 疑问句的回答: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.我有一只狗。

He has a sister and a brother.他有一个姐姐和一个弟弟。

区分 :have\ has: have用来修饰第一人称和第二人称和第三人称复数(I ,we ,they) has用来修饰第三

人称单数(she, he , it )

若表示某人没有某物,则要用否定形式,即在have\has got 后加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.

某人是否有某物则要用have\has got的疑问形式,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 的区别 两者虽都指"有",但侧重点不同。

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

<2>The fridge has got some food.

虽然都是“冰箱里有食物”但(1)句侧重于食物,(2)句侧重于冰箱。

3.be(am is are)

用法:我用am 你用are is连着她他它,单数用is,复数用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.

疑问形式把be提前 即 be+ 主语......?

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, 所用情况:

1》be + 形容词(adj.). 例:I am very happy.

2> be+ 名词(n.) 例:He is a boy.

3> be + 介词短语 例:She is in the school.

4> be+形容词短语例: He is only 11 years old.

5> be+ 副词 例:Class is over.

4. 情态动词 can

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

cannot (can't)+v.原

can没有人称和数的变化,因此谁能(不能)做某事都能用can

若表示某人是否能做某事 则要用can 的疑问形式,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?

疑问句回答 :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”时,指现在的能力,并不指过去或将来的能力。

5 . 情态动词would 想 主要用于 would you like to ...句型中,表示邀请。

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

回答一般有两种形式:1 表示愿意:I' like \ love to. 2 拒绝:Sorry, 原因。

注意:would like to 本身并不表示邀请, 而是想要。例:I would like to some books.

另外,表示邀请还能说:Let's...... Shall we...... What \ How about.......

还要注意邀请时询问信息的表达方式:1)询问时间:When is... 2) 询问地点: Where is....

6 行为动词的一般现在时

用法:

1.如果表示某人经常性或习惯性做某事,则要用行为动词的一般现在时

He goes to school every day.

They eat dinner in the evening.

2.若表示某人现在的动态,也可用一般现在时。

I know him very well. 我和他很熟。

He likes English very much. 他非常喜欢英语。

若表示否定意义,若主语是第一人称或第二人称或第三人称复数,只要在谓语动词后加not,即do not

(don't) ,若主语是第三人称单数,则要在谓语动词后加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.

若表示是否经常做某事 则要用疑问意义,将do \ does 提前即可

例:Do you write a composition every day? 你每天写一篇作文吗?

Does it smell good? 它闻起来很香吗?

注意:行为动词的一般现在时中涉及了频度副词,用法:用于行为动词之前,be动词之后

常见的频度副词有:often ,always , usually , never ,seldom ,sometimes等

7.变法总结

名词变复数(1)一般在词尾加-s 例词:bags, vegetables , books

(2)以s , x , ch , sh 结尾的加-es 例词: watches , boxes , buses , brushes

(3)以o 结尾的加-es 例词:两人两菜:heroes 英雄 negroes 黑人 tomatoes 西红柿

『肆』 人教版英语七年级上册主要学习哪些语法

1. 名词所有格
名词如要表示与后面名词的所有关系,通常用名词所有格的形式,意为"……的"。一般有以下几种形式:

(1). 一般情况下在词尾加"'s"。例如:
Kate's father Kate的爸爸
my mother's friend 我妈妈的朋友

(2). 如果复数名词以s结尾,只加"'"。例如:
Teachers' Day 教师节
The boys' game 男孩们的游戏

(3). 如果复数名词不以s结尾,仍加"'s"。例如:
Children's Day 儿童节
Women's Day 妇女节

(4). 表示两个或几个共有时,所有格应加在后一个名词上。例如:
Lucy and Lily's room Lucy 和Lily的房间
Kate and Jim's father Kate 和Jim的爸爸

动物和无生命事物的名词的所有格一般不在词尾加"'s",而常常用介词of的短语来表示。
a map of China 一幅中国地图
the name of her cat 她的猫的名字
a picture of my family 我的家庭的一张照片
the door of the bedroom 卧室的门

2. 祈使句
祈使句主要用来表示说话人的请求、命令、建议、叮嘱等意图。祈使句一般不用主语,读时用降调。为使语气委婉、礼貌,常在句首或句尾加please 。在句尾时,please前多用逗号。

(1). 祈使句肯定形式的谓语动词一律用动词原形。
Go and see. 去看看。
Come in, please. 请进。

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

3. There be 的句子结构

There be是一个"存在"句型,表示"有"的意思,
肯定句的形式为:There be + 名词(单数或复数)+地点状语或时间状语。
be动词单复数的确定,看be后边第一个名词,当所接主语为单数或不可数名词时,be动词形式为is;当所接主语为复数名词时,be动词为are;当be动词后接两个以上主语时,be动词与最临近主语保持数上的一致。意思为"某地有某人或某物"。如:
There is an eraser and two pens on the desk. 桌子上有一块橡皮和两支钢笔。
There are two pens and an eraser on the desk. 桌上有两支钢笔和一块橡皮。

(1)there be的否定句,即在be的后面加上not。
否定形式为:There be + not + (any) + 名词+地点状语。
There is not any cat in the room. 房间里没猫。
There aren't any books on the desk. 桌子上没书。

(2)there be句型的疑问句就是将be提到句首:Be there + (any) +名词+地点状语?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? 画上有一只狗吗?
---Yes, there is. 有。
---Are there any boats in the river? 河里有船吗?

(3)特殊疑问句:How many . . . are there (+地点状语)?"某地有多少人或物?"回答用There be . . .
There's one. / There are two / three / some . . .
有时直接就用数字来回答。One. / Two . . .
---How many students are there in the classroom? 教室里有多少学生?
---There's only one. / There are nine. 只有一个。/有九个。

(4)如果名词是不可数名词,用:How much + 不可数名词 + is there + 地点状语?
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?

(就10点,耐心看)

1.动词be(is,am,are)的用法
我(I)用am, 你(you)用are,is跟着他(he),她(she),它(it)。单数名词用is,复数名词全用are。变否定,更容易,be后not加上去。变疑问,往前提,句末问号莫丢弃。还有一条须注意,句首大写莫忘记。

(3)放在一起的两样东西,先说this, 后说that。如:
This is a pen. That is a pencil. 这是一支钢笔。那是一支铅笔。
(4)向别人介绍某人时说This is…, 不说That is…。如:

—Yes, this is. Who’s that? 是的,我是,你是谁?
注意:虽然汉语中使用“我”和“你”,但英语中打电话时绝不可以说:I am…, Are you…?/Who are you?

(7)在回答this或that作主语的疑问句时, 要用it代替this或that。如:
①—Is this a notebook? 这是笔记本吗?
—Yes, it is. 是的,它是。
②—What’s that? 那是什么?
—It’s a kite. 是只风筝。

3.these和those用法
this, that, these和those是指示代词,these是this的复数形式,指时间,距离较近的或下面要提到的人或事;those是that的复数形式,指时间、距离较远或前面已经提到过的人或事物。
①This is my bed. That is Lily’s bed. 这是我的床。那是莉莉的床。
②These pictures are good. 那些画很好。
③ Are those apple trees? 那些是苹果树吗?
在回答主语是these或those的疑问句时,通常用they代替these或those以避免重复。如:
④Are these/those your apples? 这些(那些)是你的苹果吗?
Yes, they are. 是的,他们是。

4.名词+’s所有格
单数名词后直接加 “ ’s ”:
Jim’s coat 吉姆的外套 Jeff’s mother杰夫的妈妈
以s结尾的复数名词,只加“’”
Teachers’ Day教师节 the twins’ books双胞胎的书
不以s结尾的不规则的名词复数,加“ ’s ”
Children’s Day 儿童节 men’s shoes男式鞋
表示两者共同拥有时,只在最后一个名词后加’s
Lucy and Lily’s mother 露茜和莉莉的妈妈(共同的妈妈,一个妈妈)
表示两者各自拥有时,要在每个名词后加’s
Lucy’s and Kate’s rooms 露茜和凯特的房间(各自的房间,两间房子)

5.There be句型
(1)There be句型主要用以表达“某处(某时)有某人(某物)。”其基本结构为“There be+某物(某人)+某地(某时)”其中there是引导词,没有词义;主语是be后面的名词, be是谓语动词,在一般现在时中be只用is和are两种形式。下面这首歌诀可帮你巧记there be句型结构:
There be放句首,主语跟在后。地、时放句末,强调置前头。如:
There is a book on the desk.
有时为了强调地点,也可把介词短语放在句首。如:
On the desk there is a book.
(2)There be句型中的be动词如何确定呢?请先看看下面这首歌诀:
Be动词,有三个,am,is还有are。“There be”真特别,不留am只留俩,那就是is还有are。要用is还是are,须看其后的名词是单数还是复数。若是单数或不可数名词用is,否则就用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”后的主语是由and连接的两个或两个以上的名词,那么be的形式要遵循“远亲不如近邻”的原则。也就是说,“be”的形式是由与它最近的那个名词来确定的。若那个名词是单数或不可数名词要用is,是复数就用are。如:
①There is a book and some pens on the floor.
②There are some pens and a book on the floor.

6.like一词的用法
like用作及物动词,译为“喜欢”。
(1)后接名词或代词,表示喜欢某人或某物。如:
I like the baby very much. 我非常喜欢这个小孩。
(2)后接动名词(v. -ing),表示“喜欢做某事”,着重于习惯、爱好。如:
Tom likes playing football. 汤姆喜欢踢足球。
(3)后接动词不定式(to do ),表示“偶尔地喜欢做某事”,着重于某次具体的行为。如:
I like reading, but I like to watch TV this evening. 我喜欢读书,但我今晚想看电视。

7.句子单数变复数,注意以下五要素
(1)主格人称代词要变成相应的复数主格人称代词,即I→we, you→you,she,he,it→ they。
如:She is a girl. →They are girls.
(2)am,is要变为are。如:
I’m a student. →We are students.
(3)不定冠词a,an要去掉。如:
He is a boy. →They are boys.
(4)普通单数名词要变为复数形式。如:
It is an apple. →They are apples.
(5)指示代词this,that要变为these,those。如:
This is a box. →These are boxes.

8.英语日期的表示法
英语中月份和星期名称都是专有名词,它们的首字母必须大写,并且前面无需用冠词。
用英语表示日期,其顺序为月+日+年,日和年之间需用逗号隔开。如:August 2nd,2003(2003年8月2日)。也可以用日+月+年来表示。如:10th May,2003(2003年5月10日)英语日期前介词的使用:若指在哪一年或哪一月,则用介词in,若具体到某一天,则需用介词on。

9.时间的表达法
(1) 直读式,即直接读出时间数字
7: 05 seven five 8:16 eight sixteen
(2) 过、差式,即几点差几分,几点过几分。(以30分为分界线)
1:25 twenty-five past one 2:30 half past two
3:43 seventeen to four 4:38 twenty-two to five
(3)12小时制
6:00 a.m. 上午6点 8:20 p.m. 下午8点20分
(4)24小时制
13:00 13点钟 22:15 22点15分
(5)15分可用quarter
4:15 a quarter past four 5:45 a quarter to six
(6)时间前通常用at.
at 5 o’clock at 7:30 p.m.

10. want用法
(1)想干什么用want to do sth
They want to join the sports club. 他们想加入运动俱乐部。
(2)第三人称单数作主语,want要作变化
①He wants to play basketball.
②Li Xia wants to play the piano.
(3)变疑问句,否定句要借助助动词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
