七年级上册英语语法

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。

2.this,that和it用法

(1)this和that是指示代词,it是人称代词。

(2)距离说话人近的人或物用this, 距离说话人远的人或物用that。如:

This is a flower. 这是一朵花。(近处)

That is a tree. 那是一棵树。(远处)

(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:

This is Helen. Helen, this is Tom. 这是海伦,海伦,这是汤姆。

(5)This is 不能缩写, 而That is可以缩写。如:

This is a bike. That’s a car. 这是一辆自行车。那是一辆轿车。

(6)打电话时,介绍自己用this, 询问对方用that。如:

—Hello! Is that Miss Green? 喂,是格林小姐吗?

—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

11.句子的变化

A.(1)含有be动词或情态动词的肯定句变否定句,在be动词或情态动词后not.

①She is a teacher. ---- She is not (isn’t) a teacher.

②He can speak English.---- He can not(can’t) speak English.

(2) 含有be动词或情态动词的肯定句变一般疑问句,把be动词或情态动词提到句首,首字母大写。(注意I变you, my变your, am变are)

①I am a student. ---- Are you a student?

②He can speak English.---- Can he speak English?

(3) 含有be动词或情态动词的肯定句变特殊疑问句,特殊疑问词

(when,where,why,who,what...,which,how...)加上由be动词或情态动词引导的一般疑问句。

①She is from America. ----- Where is she from.

B. (1)含有实义动词的肯定句变否定句,在实义动词后加don’t, doesn’t(当主语是三单时), didn’t(当时态是过去式时)(注意:助动词后要加动词原形)

① He gets up at 6. ----- He doesn’t get up at 6.
