I is, You am, She are 这样的情形。

Be的用法口诀

I用am;you, we,they都用are,is连着he,she,it;单数名词用is,复数名词全用are。变疑问,往前提,句末问号莫丢弃。变否定,更容易,be后not

莫忘记。疑问否定任你变,句首大写莫迟疑

注:

I’m=Iam我是

she’s=she is 她是

He’s=he is 他是

It’s=it is 它是

you’re=you are 你是(复数形式)

they’re=they are 他(她;它)们是

isn’t=is not 不是(单数形式)

he’s not =he is not=he isn’t他不是

二.含be动词的一般疑问句,否定句,以及回答

1.以be动词开头的一般疑问句的结构为:be动词+主语+表语(名词、数词等)。

例如:

—Is this your pencil?

这是你的铅笔

吗?

—Yes,it is. / No,it isn’t.

是的,是我的。/ 不,不是我的。

2.将肯定的陈述句变为否定的陈述句的方法:1找到be动词,在be动词之后加上not就可以了,其他的不变。

例如:(肯定的陈述句)This is my bike.

(否定的陈述句)

This is not my bike.---- This

isn`t my bike.

3. 将陈述句变为一般疑问句时,应将be动词移到主语之前并大写其

首字母,句末标点用问号,其他句子成分照搬。(注意,my变your,其他人称不变)。例如:This is my bike. 这是我的自行

车。→Is this your bike?这是你的自行车吗?

4. 一般疑问句通常用yes或no来回答。

例如:—Are you Gina?你是吉娜

吗?—Yes,I am. / No,I’m not.是的,我是。/ 不,我不是。

有些一般疑问句也可以用其他形式来回答。

例如:

—Is this Gina’s book?这是吉娜的书

吗?—Sorry,I don’t know.对不起,我不知道。

be动词详解及精选练习题150道

be动词是我们必须掌握的一个重要概念,虽然be动词少,但是由于其形式多变,给很多同学的英语学 习造成了一定的困难,下面主要就be动词作一个专题复习。 1. be动词的概念: be动词是系动词的一种,是与一般动词(实义动词)相区别的概念。一般动词表示具体的动作。 而be动词不是动作,它通常与名词、形容词或其它词类一起表示主语的性质、状态、身份、特点 等等。一般动词很多,如:walk(走卜read(读)、stand(站立)等等,而be动词只有一个,那就是be, 所以它称为be动词。be动词在不同的句子中有不同的中文意义,有时甚至不用翻译其意义。be 动词有不同的形式,女口:现在式有am, are, is三种,过去式有was和were两种,过去分词只有been 一种形式。 2. be动词的现在式用法: be动词的现在式有am, are, is三种,具体用哪一种,必须由主语的人称和数决定。如下表所示: be动词用法歌:动词用法歌:我用am,你用are,is连接他,她,它。你用,连接他,单 数名词用is,复数名词全用are。,。变疑问,往前提,句末问号莫丢弃。变疑问,往前提,句末问号莫丢弃。变否定,更容易,莫忘记。变否定,更容易,be后not莫忘记。疑问否定 任你变,句首大写莫迟疑。疑问否定任你变,句首大写莫迟疑。 3. be动词的过去式用法: be动词的过去式是:was和were,这两种形式与现在式用法没有多大区别,作谓语时用哪一种,还 是由主语的人称和数决定。如

⑶疑问句:be动词+主语如:(a) 一般疑问句及其回答: Are you a student? 回答:Yes, I am. No, I am not. 注意:含be 动词的一般疑问句回答用Yes 或No. 其结构是: Yes, + 主语+ be 动词/ No, + 主语+ be 动词+ not. (b) 特殊疑问句: What is your name? How are you? Where is my pencil-box? 4. There be 句型: there be 句型是含有be 动词的一个重要句型。其结构如下: there + be 动词+ 名词+ 地点状语 There is a school there. 那里有一个学校。 在这个句型中a school是真正的主语,be动词的形式由它决定。当这个名词是单数时, is或was,当 be 动词是这个名词是复数时,be动词用are或were。如: There are many students in the classroom. 在教室里有许多学生 There was an accident in the street last night. 昨晚这街上有个车祸。 There were lots of people in the room when I got in. 当我进去的时候,屋里有很多人。 there be句型的一般疑问句是将be动词提前,否定句也是将be动词后面加上not,女口: Is there any water in the bottle? 瓶子里有一些水吗? There aren ' t any students in the roo B间里没有任何学生。

Be动词和助动词用法辨析

Be动词和助动词用法区别其实be动词也是助动词(auxiliary verbs)。 英语动词大致可分为三种:助动词(auxiliary verbs),情态动词(modal verbs),实意动词(full verbs)。 助动词(auxiliary verbs):do,be,have。没有实意,“帮助”别的动词,表示时态,否定和提问。情态动词(modal verbs):can,must,may。也是“帮助”别的动词,但是有自己的实意。实意动词(full verbs):play,run,think。其他有实意的动词。 be动词可用作助动词(auxiliary verbs):1,be+Ving:所有的进行时态,如:2,be+过去分词:被动式。 be动词也可用做实意动词(full verbs):be[bi]v.有;在;是。 你这样想,一个句子里要有动词吧。再看看它们的名字,“be 动词”和“助动词”, 先说“be动词”,(1)这名字里有动词,说明他是动词,句子里有他就不会有别的动词(除非这些动词以别的形式出现,这是后话)了,(2)“am,is,are,was,were”叫be动词,是因为他们是be的不同形式 再说“助动词”,(1)一定要注意“助”,是帮助的意思,说明他不是动词,只是起到了辅助的作用,所以,他们就一定要与动词同时出现。[记住啊,他们离不开动词,但是动词没有他们也是可以的]

(2)did,do,does只是do的不同形式,根据你所需要的时态来选择(1)用于肯定句,否定句和疑问句 am:第一人称单数(即只与I连用),用于现在时(一般现在,现在进行,只要那时态中是现在的就行)eg:①I am a girl.一般现在时②I am eating an apple.现在进行时 ③I am going to do my homework.[be going to表将来,将来中只有这一种] is:第三人称单数,用于现在时(一般现在,现在进行,只要那时态中是现在的就行)(it就不举例了)eg:①She/He is a girl/boy.一般现在时②He/She is eating an apple.现在进行时③He/She is going to do his homework.[be going to表将来,将来中只有这一种] are:第二人称单数,所有人称复数,用于现在时(一般现在,现在进行,只要那时态中是现在的就行)eg:①You are a girl. We/You(你们)/They are girls.一般现在时②You are eating an apple.We/You(你们)/They are eating apples.现在进行时③We/You(你们)/They are going to do our/your/their homework.[be going to表将来,将来中只有这一种] was:第一人称单数,第三人称单数,用于过去时(一般过去,
