英语语法be动词与助动词do用法

英语语法be动词与助动词do用法
Don't be so absent-minded. 不要这么心不在焉。
说明: 构成否定祈使句只用do,不用did和does。
初一英语:助动词Do和Be在疑问句里怎样选择使用?
如果句子里的谓语是实义动词时,疑问句就要用助动词DO。
For example:
1、I give him a book 。
He doesn't liLeabharlann e to study. 他不想学习。
In the past, many students did not know the importance of English. 过去,好多学生不知道英语的重要性。
3) 构成否定祈使句,例如:
Don't go there. 不要去那里。
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,
因为句中give是实义动词,所以这个句子要变为疑问句的话前面就应该用助动词
Do you give him a book .
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。

Be动词和助动词用法区别

Be动词和助动词用法区别

精选文档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(auxiliaryverbs ), 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 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: ① I am a girl. 一般现在时② I am eating an apple. 现在进行时③ I 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)般现在时② He/She is eating an apple. 现在进行时eg: ① She/He is a girl/boy.③ He/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: ① You are a girl.We/You(你们)/They are girls. 一般现在时② You are eating an apple.We/You(你们)/They are eating apples. 现在进行时③ We/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,过去进行,只要那时态中是过去的就行)(it 就不举例了)eg:① She/He was a girl/boy. —般过去•时回答be 是一个连系动词,它有自己不同的形式现在时: be 进行时: being 过去时: was/were 过去分词: been 它的后面必须跟形容词或名词作表语,与之构成系表结构,充当句子的谓语。

be动词和助动词的用法口诀

be动词和助动词的用法口诀在英语学习中,be 动词和助动词的用法是非常重要的基础知识,但对于许多学习者来说,也是容易混淆的难点。

为了帮助大家更清晰地理解和掌握它们的用法,下面为大家总结了一些简单易懂的口诀。

一、be 动词的用法口诀我用 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。

“我用 am,你用 are,is 连着他她它”这句口诀很好理解。

当主语是第一人称“I”(我)的时候,be 动词用“am”;当主语是第二人称“you”(你)的时候,用“are”;当主语是第三人称“he”(他)、“she”(她)、“it”(它)时,用“is”。

例如:I am a student(我是一名学生。

)You are my friend(你是我的朋友。

)He is a doctor(他是一位医生。

)She is very beautiful(她非常漂亮。

)It is a dog(它是一只狗。

)“单数名词用 is,复数名词全用are”是指当主语是一个单数的名词时,be 动词用“is”;当主语是复数的名词时,用“are”。

比如:This pen is red(这支钢笔是红色的。

)Those books are mine(那些书是我的。

)要将陈述句变为疑问句,需要把 be 动词提到主语前面,句末加上问号。

像:She is a teacher (她是一名老师。

)变为疑问句就是:Is she a teacher? (她是一名老师吗?)将陈述句变为否定句,就在 be 动词后面加上“not”。

例如:They are happy (他们很开心。

)否定句就是:They are not happy (他们不开心。

)二、助动词的用法口诀助动词,挺神奇,帮助实义动词变形式。

do/does 用于一般现在,did 过去常出现。

否定疑问靠它们,动词原形跟后面。

Be动词和助动词用法区别

Be动词和助动词用法区别

B e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 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,过去进行,只要那时态中是过去的就行)(it 就不举例了)eg:①She/He was a girl/boy.一般过去·时回答be是一个连系动词,它有自己不同的形式现在时:be 进行时:being 过去时:was/were 过去分词:been它的后面必须跟形容词或名词作表语,与之构成系表结构,充当句子的谓语。
