be动词有哪些,我才上5年级请说清楚些!
be(原型)
一般现在时

is(主语是单数)
are(主语是复数或者you)
一般过去时
was(主语是单数)
were(主语是复数)
一般将来时

be going to + 动词原形

am is are(过去式前俩个was 后were)

一般现在时
am
is
are

一般过去时
was/am is
were/are

一般将来时
will be
be going to + 动词原形


我四年级就知道而且会用了!

be动词有am is are三个 都翻译成“是”
am 第一人称(我)用 比如 i am student我是学生
is 第三人称(他 她 它 以及人名)用 比如 he is student他是学生
are 第二人称(你)及复数用 you are student 你是学生 they are students他们是学生 (他们---复数)

呵呵,不错嘛,这么小就将要掌握这个知识点了。我的小学升初中的学生都没掌握全呢!
你们最常见的是am is are
还有是表达过去的意义时用的was were.
没有了。就这么简单。
我只有80%把握我是完全正确的,你要权衡一下哈。

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...

全部展开

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”是个特别动词;有些语言,如中文和马来文,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.
2. Mary's new dresses are colourful.
3. I have been there before.
4. Mother is in the kitchen now.
【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.】“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.
