初一英语上册语法总结

  导语:初一英语的语法比较简单,我们可以很轻松地总结出来,下面是小编收集整理的初一英语上册语法总结,欢迎参考!

一.动词be(is,am,are)的用法:说明身份,年龄,状态等。

  口诀: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。

  be动词的用法:

  be动词包括“am”, “is”, “are”三种形式。

  第一人称单数(I)配合am来用。

  句型解析析:I am+…

  I am a student. I am a boy.

  第二人称(You)配合are使用。

  句型解析:You are+…

  You are my good friend. You are a good person.

  第三人称单数(He or She or It)配合is使用。

  句型解析:She(He, It) is +…

  She is a good girl. She is so cute.

  人称复数 (we /you/they)配合are使用。

  句型解析:We (You, They) are +…

  We are in Class 5,Grade 7. You are good students.

  注意:

  1 综合解析当使用be动词的时候,前面请先加上第几人称。

  be动词前面的人称,是不可随意替换的。例如:

  I am, You are, She is,并不会出现I is, You am, She are 这样的情形。

  2 当只有第一人称和第二人称或第三人称时应该把第二人称或第三人称放在前

  例如:you and I, Tom and I

  当第二人称和第三人称放在一起时把第二人称放在前面,

  例如:you and Tom

  当三者都有时,排序为:2 3 1

  例如you, Tom and I

  练习:1. Where ______ Ann . She ______ here.

  2. How old ______ you . I ______ thirteen.

  3. ______ you Mr Read . Yes, I ______.

  4. What ______ your name. My name ____ Ann

 二 情态动词Can

  1 can作“能、会”解,否定式是cannot,缩写为can’t。

  “can+动词原形” “can’t+动词原形” :表示某人能做或不能做某事

  Can 是情态动词,没有人称和数的变化。

  Can 表示的”能力”为现在的能力,而不是过去或将来的能力。

  1). for ability表示能力。例如:

  —Can you write in English? —Yes, I can.

  I can run fast,can you?

  2). indicating acquired knowledge or skill表示获得的知识或技能。例如: —Can she speak Japanese? —No, she can’t.她会说日语吗?不,她不会。

  3). indicating permission表示许可。例如:

  Can I read your newspaper?我能看看你的报纸吗?

  Can I take you home?我送你回家行吗?

  We can’t wear jeans at work.我们上班时不准穿牛仔裤。

  4). indicating requests表示要求。例如:

  Can you help me with this box?你能帮我弄这个箱子吗?

  Can you feed the cat?你喂喂猫好吗?

  5). indicating possibly表示可能性。例如:

  That can’t be Mary—she’s in hospital.那不可能是玛丽—她住院了。

  He can’t have slept through all that noise.那么吵他不可能睡得着觉。

  There’s someone outside—who can it be?外面有人—会是谁呢?

  6). used to make suggestions用以提出建议。例如:

  We can eat in a restaurant, if you like.你愿意的话,咱们可以在饭馆吃饭。

  I can take the car if necessary.必要时我可以开车去。

 三 情态动词Would

  1 Would是will的过去式,可用于各人称,表示过去时间的"意志"、"愿望"和 "决心"等。 如:I told peter that I would go along wit him.我告诉彼得我要跟他一块去。

  2 would用来表示现在时间时时,不论是表达说话人本身的意志或向对方提出请求,均较will婉转。如:

  Would you like to have a glass of wine? 你要喝杯酒吗?

  Would you please tell me the way to the nearest bus-stop?

  [注]在日常会话中,I would like to和I should like to都可以说,I would like的简略式为I'd like。如:yes, I’d like to. Yes, I’d love to

  Yes, very much. Sorry, ai already have an appointment.

  3 Would还可以表示过去习惯发生的动作

  I found that retired persons would often go to the park to play chess.我发现退休的人经常到公园里下棋。

  When he had a problem to solve,he would work at it until he found an answer.当他有个问题要解决时,他总是想办法一直到找到答案为止。

  练习:

  1 -Can you speak Japanese? -No, I____.

  A. mustn't B. can't C. needn't D. may not

  A. can't B. can C. mustn't D. must

  6 -Would you like to go boating with us? -Yes, ___.

  A. I'd like B. I want C. I'd like to D. I do

  四 “there be”句型

  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。 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:
