1)协助主要动词构成谓语动词的词叫助动词。被协助的动词称作主要动词。助动词自身没有词义，不可单独使用。例如：

(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。(北京安通学校提供)
He has got married. 他已结婚。

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：

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等。
3 助动词be的用法
1) be +现在分词，构成进行时态。例如：

English is becoming more and more important. 英语现在越来越重要。(北京安通学校提供)
2) be + 过去分词，构成被动语态。例如：
The window was broken by Tom.. 窗户是汤姆打碎的。
