譽(yù)德教育英語小課堂:
一、助動(dòng)詞
助動(dòng)詞本身沒有詞義,不能單獨(dú)作謂語,只能和主要?jiǎng)釉~一起構(gòu)成謂語動(dòng)詞,表示否定、疑問、時(shí)態(tài)、語態(tài)等語法形式,或用來加強(qiáng)語氣。常用的助動(dòng)詞有:be, do, have, shall, will等。它們的具體用法如下:
(1)助動(dòng)詞be
a. 可用于構(gòu)成進(jìn)行時(shí)態(tài)
she is doing her homework now.
i asked him what he had been doing all afternoon.
b. 可用于構(gòu)成被動(dòng)語態(tài)
the baby was put in bed by his mother.
the invitation was received yesterday.
c. 可與動(dòng)詞不定式構(gòu)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(dòng)詞have
a. 構(gòu)成完成時(shí)態(tài)
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(dòng)詞不定式構(gòu)成謂語,表示因客觀環(huán)境促使不得不做的事情
she had to go shopping yesterday.
(3)助動(dòng)詞do
a. 構(gòu)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(qiáng)語氣
i do want to have a talk with you
do come and see me.
c.用來代替動(dòng)詞詞組
have you finished your work?yes, i did yesterday.
he plays basketball well. so does his brother.
(4)助動(dòng)詞shall
構(gòu)成將來時(shí)態(tài),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(dòng)詞will
構(gòu)成將來時(shí),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(qū)別
must是情態(tài)動(dòng)詞,意思是“必須”、“應(yīng)該”、“一v定要”,后接動(dòng)詞原形。must的否定形式為mustn’t.構(gòu)成疑問句時(shí),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(shí)態(tài)。
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(xiàn)在不再有的習(xí)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 ?
