最好是一两句话
1）协助主要动词构成谓语动词词组的词叫助动词（Auxiliary Verb）.被协助的动词称作主要动词（Main Verb）.构成时态,语态是助动词
助动词是语法功能词,自身没有词义,不可单独使用,它没有对应的汉译,例如：
He doesn't like English.他不喜欢英语.
（doesn't是助动词,无词义；like是主要动词,有词义)
2） 助动词协助主要动词完成以下功用,可以用来：
a.表示时态,例如：
He is singing.他在唱歌.
He has got married.他已结婚.
b.表示语态,例如：
He was sent to England.他被派往英国.
c.构成疑问句,例如：
Do you like college life?你喜欢大学生活吗?
Did you study English before you came here?你来这儿之前学过英语吗?
d.与否定副词not合用,构成否定句,例如：
I don't like him.我不喜欢他.
e.加强语气,例如：
Do come to the party tomorrow evening.明天晚上一定来参加晚会.
He did know that.他的确知道那件事.
3） 最常用的助动词有：be,have,do,shall,will,should,would
be动词的用法
be
[bi:]
vi
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.
