Be do和does的用法
Be do和does的用法

系动词Be(am, is, are)的用法

一、请记住以下口诀:

我用am,你用are,is连着他,她,它;

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。

二、Be动词在一般过去时中的变化:

1.am 和is在一般过去时中变为was。(was not = wasn’t)

2.are在一般过去时中变为were。(were not = weren’t)

3.带有was或were的句子,其否定、疑问的变化和am,is, are一样,即否定句在was或were后加not,一般疑问句把was或were调到句首

am,is are 都属于be动词,be是他们的原型

be动词的一般现在时有三种形式,即:am, is, are。

1. 如果主语是第一人称I(我)时,be动词用am。

如:I am a student. 我是一名学生。

I am 还可缩写成I'm。如:

I'm David. 我是大卫。

2. 如果主语是you (你,你们), they (他们,它们,她们)或名词复数(两个以上的人或物)时,be动词必须用are。如:Are you twelve? 你是十二岁吗?

Tom and Lily are good friends. 汤姆和莉莉是好朋友。

They are at school. 他们在学校。

are与主语还可缩写。如:We are= We're,They are =They're, You are = You're。而are与not可缩写成aren't。

如:They aren't students. 他们不是学生。但是am与not不能缩写。

3. 如果主语是单数名词、不可数名词或单数第三人称代词(he, she, it)时,be动词用is。

如:My mother is a teacher. 我的妈妈是一名老师。

He is a student. 他是一名学生。

is也可与主语缩写,如: He is = He's, My mother is = My mother's等。但是This is不可缩写。而is与not可缩写成isn't。如:This isn't a book. 这不是一本书。

根据以上叙述我们可以把动词的用法以口诀的形式表述出来:

我(I)是am,

你(you)是are,

剩下is留给她(she), 他(he), 它(it),

两个以上都用are。

be动词am,is,are,如何正确使用它。我用am,你用are,is用于他、她、它。以上主语是单数.

复数主语全用are。指示代词作主语,This,that用is,These,those要用are。若是变为否定句,Not系动词后面加。若变一般疑问句,句首A m,Is,Are,句末问号莫忘加。回答一般疑问句,Yes,或N o简回

do和does的用法

do 这个词(does是第三人称单数形式),大体上从两方面来讲。

1.作为行为动词,跟其他动词一样,如study, play等。他的意思是“做”等。如:

We usually do our homework in the afternoon.

He does his homework in the evening.

2.作为助动词,也就是帮助主要动词构成否定和疑问等。

We don't like bananas.

Do you like apples?

Does he like English?

He doesn't like swimming.

上面有一句He does his homework in the evening.要是变成否定句就成了这个样子:

He doesn't do his homework in the evening.

这里加上了助动词doesn't,而原来的主动词does变成原形do了。

作为助动词的do和does是没有词义的,它们在句中的构成一般现在时的疑问句和否定句.

Do用于主语第一人称,第二人称和第三人称复数形式的句中,does用于主语第三人称单数的句中。

Eg. Do you want to be a teacher? 你想成为一个老师吗?

Do his friends go to park every day? 他的朋友们每天都去公园吗?

I don’t like him. 我不喜欢他。

Where does Tom come from? 汤姆来自哪里?

I do n’t know.我不知道。

He doesn’t live here. 他不住在这儿。

will/can/could/would/should/shall 等助动词后面加be

其他时候, 第一人称I后面用am

第二人称, 复数, 用are

单数用is...

What do I do? 该怎幺办呢? What do you do? 你当时做什幺? Do good 有益,促进健康,使满意Do into 把……译成

Do john? 约翰呢? Do over 清扫,重新装饰Do this. 做这个。 Do well 成功,做得好

They do. 他们住在那儿。 does. everybody does. 每个人都是这样。Yes, it does. 也合乎实际。

Perhaps,he does. 或许,他要打。 He does not go. 他没去。 What does that do? 有什么用途? Yes, he does. 是的,他有。

Yes, it does. 是的,它是。 Does Alice speak English? 爱丽丝讲英语吗? Does he like coffee? 他喜欢咖啡么? Does he study English? 他学英语吗?

Be,do和does的用法

系动词Be(am, is, are)的用法 一、请记住以下口诀: 我用am你用are , is连着他,她,它;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。 be动词的一般现在时有三种形式,即:am, is, are。 1. 如果主语是第一人称I (我)时,be动词用am。 如:I am a student. 我是一名学生。 I am 还可缩写成rm。如: rm David.我是大卫。 2. 如果主语是you (你,你们),they (他们,它们,她们)或名词复数(两个以上的人或物)时,be动词必须用are。 如:Are you twelve? 你是十二岁吗? Tom and Lily are good frie nds. 汤姆和莉莉是好朋友。 They are at school. 他们在学校。 are 与主语还可缩写。如:We are= We're ,They are =They're, You are = You're 。而are 与not可缩写成aren't。 如:They aren't students. 他们不是学生。但是am与not不能缩写。 3. 如果主语是单数名词、不可数名词或单数第三人称代词(he, she, it)时,be动词用is 如:My mother is a teacher. 我的妈妈是一名老师。 He is a stude nt.他是一名学生。 is也可与主语缩写,如:He is = He's, My mother is = My mother's 等。但是This is不可缩写。而is与not可缩写成isn't。 如:This isn't a book. 这不是一本书。 根据以上叙述我们可以把动词的用法以口诀的形式表述出来: 我(I )是am, 你(you)是are, 剩下is留给她(she),他(he),它(it), 两个以上都用are. 练习: Be 动词练习题: 1.

在什么情况下用do和does

在什么情况下用do和does do 这个词(does是第三人称单数形式),大体上从两方面来讲。 1.作为行为动词,跟其他动词一样,如study, play等。他的意思是“做”等。如: We usually do our homework in the afternoon. He does his homework in the evening. 实义动词的一般现在时的否定句或疑问句应借助于助动词do或does来构成。 2.作为助动词,也就是帮助主要动词构成否定和疑问等。 We don't like bananas. Do you like apples? Does he like English? He doesn't like swimming. 上面有一句He does his homework in the evening.要是变成否定句就成了这个样子: He doesn't do his homework in the evening. 这里加上了助动词doesn't,而原来的主动词does变成原形do了。 关于动词have(has)的用法 have用于第一人称(I, we),第二人称(you), 及第三人称复数(they);has用于第三人称单数(he, she, it)或单数名词。 1. have的用法总结 (1)have作“有”讲,强调“所属关系”,含有“拥有”之意。其主语一般是人,有时也可是物。They have many new books. 他们有许多新书。 Wei Hua has a little brother. 魏华有个小弟弟。 This table has four legs. 这张桌子有四条腿。 (2)have可以作“买”讲。 I want to have a kilo of beef. 我想买一公斤牛肉。 May I have a new pen? 我可以买支新笔吗? (3)have作“用、使用”讲 Excuse me, may I have your bike, please? 打扰了,我可以用(借用)你的自行车吗? (4)have+表示动作的名词(这类名词常由同形的动词转化而来)意为“做(某事)”(=do sth. )。have a drink (of…)喝一点(……) have a look(at…)(朝……)看一眼 have a rest休息一下 have a swim游泳这些短语常用于口语,这里的have可以用take替换。 (5)have+表示一日三餐的名词,意为“用餐”。 have breakfast/lunch/supper 吃早饭/午饭/晚饭。have dinner吃饭,吃晚饭。 (6)have+表示食品、饮料等的名词,意为“吃;喝”(=eat, drink)。如: have(some) bread吃面包 have eggs(for breakfast)(早餐)吃鸡蛋 have(a cup of )tea 喝(一杯)茶 这里的have也可以用take替换。 (7)have+表示某种活动的名词,意为“进行;举行”。如: have a class(学生)上课 have a sports meeting开运动会 have a party举行聚会 (8)have+表示疾病的名词,意为“患(病)”,有时也用have got。
