be动词用法与例句AM IS ARE的例句
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.
i am a student主语：i 谓语：am a student（系表结构）
being是它的现在进行时态,一般不单独用,而是用于现在进行时的被动语态.（being+动词过去分词）
the bike is being repaired.单车正在被修理中.
it is being finished by him这正在被他完成中.
been是它的过去分词,也不一般单独使用,而是用于现在完成时、过去完成时以及需要它的句子.
i have been here for a long time.我已经到这里有一段时间了.
至于你的问题,这与你想表达的意思有关.
你的工作是什么?
what do you do? what is your job?
那么这里选用do和is有什么根据呢?
第一句里面,第二个do是指你做什么,也就是你的工作,就是一个实义动词.按中文说,what you do已经足够了.可是英语里面就不行,必须跟一个助动词,也就是do.
这里就有了一个结论：当句子中有动词时,我们就用助动词do或是does.如果没有动词时,我们就选用is或是are,也就是b“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.

不用这么复杂吧...人家是初一的耶...
你只要记住，初一的句式都比较简单，be动词紧跟在主语后面，I与am搭配，you/we/they等复数的主语（比如my parents lily and lucy)与are搭配〔you不管翻译成“你”还是“你们”都与are搭配〕，he/she/it等单三人称（比如 Mr.lee Jack)作主语时，谓语用is
eg:
I am...
