be动词的用法及其口诀
10:41&&作者:&&来源:互联网&&字号:|
对于初中英语知识来说,掌握动词的用法是初中考试中的重点。对于初中英语中最主要的动词就是Be。be动词有那些用法呢?他的am, is,
are变形是在什么时候,以及他的过去式was, were如何应用呢?下面小编对be动词的用法进行了总结,希望能够给为初中学生学习英语提供帮助。
一般be动词的单复数形式大家还是不叫了解的,不如单数is,复数are。除了这些单复数之分之外be还是一个多功能动词,在初级英语里常见的四种用法:
一,系动词be
be为连系动词,中心词义是"是",句型为"主+系+表"结构。be的形式常用am, is, are(现在式);was,
were(过去式);will/can/may/must be(助动词/情态动词+原形);have/has/had been(助动词+过去分词)等。如:
To help animals is helping people.(一般现在时)
The twins were very busy yesterday.(一般过去时)
It will be sunny tomorrow.(一般将来时)
She has been ill for over a week.(现在完成时)
二,助动词be
助动词be,无词义,辅助主要动词一起在句中作谓语动词。用法如下:
1. be+doing:构成进行时态,有现在和过去两种进行时态。如:
The girls is reading and copying the new words now.
Young Tom was always asking questions and trying out new ideas.
2. be+done:构成被动语态(主语是动作的承受者,done必须是及物动词)。如:
Tea is grown in my hometown.(一般现在时的被动语态)
This building was built three years ago.(一般过去时的被动语态)
Our classroom has been cleaned and tidied already.(现在完成时的被动语态)
How could this kind of cakes be made in your home?(含情态动词的被动语态)
That is a day never to be forgotten.(动词不定式的被动语态)
3. be+going to do,表示"打算或将要做某事",be有现在和过去两种形式。如:
We are going to plant trees in the park.
I didn't know if she was going to come here.
4. be+to do,表示"按计划安排将要做某事"。如:
The new shop is not to be opened till next Monday.
One night an angel came to Mary and told her that she was to have this
special boy.
三,be动词的用法there be句型
there be句式为:there be+主语部分+状语部分,表示"某处存在某物",be常用现在时,过去时和将来时等。如:
Oh, cool! And there are many things to see. There is even a deer park in
There are about 80 pyramids in Egypt.
Will there be a football match in your school next week?
四,实义动词be
可以将be视为实义动词,因为它具有实际的词义,如"成为;做;发生;举行;逗留;到达"等。如:
His daughter wants to be a doctor for animals in her twenties.
Kate's birthday party will be at half past six this evening.
Jim has been in China for more than two years, but he has not yet been to
以上be动词的用法的四个功能中,第一个功能最常见,第三个功能是考试的重点也是难点。为了方便大家对Be动词用法的记忆,小编还给大家总结了be动词的用法的常用口诀: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。

英语连系动词用法要览
17:01:01&&
英语连系动词用法要览:连系动词是表示不完全谓语关系的动词,它与其后的表语一起构成谓语。常见的连系动词有be(是),become(成为),get(变成),remain(还是),seem(似乎是),look(看上去),feel(感觉)等。
一、连系动词基本用法 连系动词是表示不完全谓语关系的动词,它与其后的表语一起构成谓语。常见的连系动词有be(是),become(成为),get(变成),remain(还是),seem(似乎是),look(看上去),feel(感觉)等。连系动词后的表语通常是名词和形容词,有时也可以是代词、数词、副词、介词短语、不定式、动名词、从句等: His English is excellent. 他的英语很棒。(跟形容词) He is a famous poet. 他是著名诗人。(跟名词) Money isn&t everything.金钱不是一切。(跟代词) She was the first to arrive.她是第一个到达的人。(跟数词) Who is upstairs? 谁在楼上?(跟副词) He is with his friends. 他和朋友在一起。(跟介词短语) He seems to be ill. 他似乎病了。(跟不定式) Seeing is believing. 眼见为实。(跟动名词) This is what you need. 这就是你需要的。(跟从句) 二、学习连系动词应注意的两点 1. 关于连系动词后接副词作表语 连系动词后通常可接形容词作表语,一般不接副词: 误:His English is very well. 他的英语很好。(应将well改为good) 误:Be carefully. 小心点。(应将carefully改为careful) 误:The soup tastes nicely. 这汤味道不错。(应将nicely改为nice) 但是,有时连系动词后也可接副词作表语,不过这主要限于in, on, off, out, away, behind, up, down, over, through, around, round, below, inside, outside 等少数副词小品词以及here, there, upstairs, downstairs等少数表示地点或方位的副词: Mother wasn&t in last night. 母亲昨晚不在家。 The meeting was over at five. 会议五点结束。 Come along. The taxi is outside. 来吧,出租车在外面。 Mother is downstairs waiting for you. 母亲在楼下等你。 2. 关于连系动词后接不定式 (1) 连系动词be后根据情况可自由地接不定式作表语: My dream is to be a scientist. 我的梦想是当一名科学家。 All I could do was to wait. 我只能等。 My plan was to go from London to Paris. 我计划从伦敦去巴黎。 I was to have seen Mr Kay. 我本要去见凯先生的。 (2) seem, appear, prove, continue, turn out, get, grow, come 等连系动词后也可接不定式(尤其是to be)作表语: She always seems to be sad. 她常常显得很忧伤。 My advice proved to be wrong. 我的意见证明是错的。 She appears to have many friends. 他好像有很多朋友。 The weather turned out to be fine. 天气结果很好。 Circumstances continue to be favorable. 情况仍然是有利的。 He has grown to like studying English. 他渐渐喜欢学英语了。 【注】若所接不定式为to be,通常可以省略。不过,若其后接的是表语形容词,则to be通常不宜省略。另外,连系动词look后能否接to be似乎尚有争论,不过,在现代英语中接to be的现象已较普遍。 (3) sound, smell, feel, taste, become等连系动词后通常不能接不定式: 误:These oranges taste to be good. (应去掉to be) 误:The roses smell to be nice. (应去掉to be) (4) 有的连系动词后接的从句可用不定式来改写: It seems that she&s right. / She seems to be right. 她似乎是对的。 It appears that you have made a mistake. / You appear to have made a mistake. 似乎你弄错了。

be 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。
疑问否定任你变,句首大写莫迟疑。
be动词的用法:be (be/is/are/am/was/were)
现在时 I am, you are, he is, we are, you are, they are (缩略式 I'm, you're, he's, we're, you're, they're), (否定缩略式 I'm not, isn't, aren't), 过去时 I was, you were, he was, we were, you were, they were (过去时否定缩略式 wasn't, weren't), 过去分词been, 现在分词being
英语的“be”是个特殊动词;有些语言,如马来文等,并没有“be”这样的动词。
“Be”除了原形的“be”之外,还有另外七种形式:am, is, are, been, being, was, were.
在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)
【当主动词时,“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。例如:
1. The man is a science teacher.
这个男子是一位科学教师
2. Mary's new dresses are colourful.
玛丽的新衣服色彩鲜艳
3. I have been there before.
我以前去过那里
4. My mother is watching TV in the room.
母亲现在在客厅看电视 
【这四个都是陈述句,可以变成疑问句,方法简单,把主语和“be”或助动词对换位置即可:
5. Is the man a science teacher?
6. Are Mary's new dresses colourful?
7. Have I been there before?
8. Is mother in the kitchen now?
【当“be”要在祈使句中出现时,它必须借重助动词“do”或“don't”之助,如:
9. Don't be silly!
10. Do be obedient!
11. Don't be a fool!
【“Be”有两种缩写法,如下:
12. He's not...../He isn't....
13. You're not...../You aren't...
【但“am + not”的缩写法只有一个:
14. I'm not.
有人用“ain't”, 但这并不是标准英语。
谈过了“be”作主动词的功能,现在看看“be”作助动词时,有些什么用法:
【1.】“Be + 现在分词”以组成进行式时态(Continuous Tenses),如:
15. Tony's maid is washing his new car.
16. The children are playing in the field.
17. Samuel was eating when I came in.
18. We have been living here since 1959.
【2.】“情态动词+Be + 过去分词”以组成被动语态(The Passive Voice),如:
19. Her money in the drawer was stolen.
20. A number of good jobs are taken up byforeigners.
21. David studied in Taiwan but has been trained as a language lecturer in America.
22. Can all the wonderful birds be found in our Bird Park?
23. The disobedient boy was told to stand out- side the classroom.
24. Steps are being taken to reduce traffic con- gestion during peak hours.
25. Dishonest students will be immediately dealt with.
