譽德教育英語小課堂：
一、助動詞
助動詞本身沒有詞義，不能單獨作謂語，只能和主要動詞一起構成謂語動詞，表示否定、疑問、時態、語態等語法形式，或用來加強語氣。常用的助動詞有:be, do, have, shall, will等。它們的具體用法如下：
（1）助動詞be
a. 可用于構成進行時態
she is doing her homework now.
i asked him what he had been doing all afternoon.
b. 可用于構成被動語態
the baby was put in bed by his mother.
the invitation was received yesterday.
c. 可與動詞不定式構成謂語
these books are not to be taken out of the room.
she is to arrive at six this morning.
（2）助動詞have
a. 構成完成時態
i have not seen him for three years.
how long has your uncle taught in the village?
he had lived in scotland for fifteen years before he came to england.
b. 和動詞不定式構成謂語，表示因客觀環境促使不得不做的事情
she had to go shopping yesterday.
（3）助動詞do
a. 構成疑問句和否定句
did anyone sharpen this knife?
i don’t think you are right.
b．用來加強語氣
i do want to have a talk with you
do come and see me.
c．用來代替動詞詞組
have you finished your work?yes, i did yesterday.
he plays basketball well. so does his brother.
（4）助動詞shall
構成將來時態，單純表示未來情況
i shall not be back tonight.
we shall pay a visit to the banpo ruins next month.
（5）助動詞will
構成將來時，用于第v一、二、三人稱。如：
they will move to a new house.
she will not eat any solid food.
注意：
（1）have to 與must的區別
must是情態動詞，意思是“必須”、“應該”、“一v定要”，后接動詞原形。must的否定形式為mustn’t.構成疑問句時，肯定回答一般用must。否定回答用needn’t或don’t have to 表示“不必”。如：
must i do it now ?
yes, you mustno, you needn’t.
have to 表示“不得不，必須”，可用于多種時態。
i missed the train, so i had to take a taxi.
i’m sorry i won’t go with you, i’ll have to go to the bank.
we don’t have to install this new television set.
（2）used to 表示過去常常，而現在不再有的習慣。其否定形式為: used not to, usedn’t (usen’t) to , didn’t use to.
i used to go to work by bus. now i go by car.
i used to collect stamps when i was a boy.
used they to have a lot more free time ?
