can can和may的区别
A. 定义:情态动词是一类用于表示说话人的语气和情态的助动词.常表示命令、请求、拒绝、义务、可能、需要等.can和may是其中两个.
B. 情态动词的几个特征:
①情态动词不同于实义动词,不可单独作谓语,只有跟实义动词连用才有意义;
②情态动词没有人称和数的变化;
③情态动词后的动词必须用原形.
C. can的用法:
①表示有能力做某事,意为“能、会”.如:
The girl can sing in English.
②表示许可,意为“可以”,如:
You can drive my car to the post office.
③表示推测,意为“也许,可能”.如:
He can’t be your brother,you don’t look the same.
D.may的用法:
①表示请求,语气比can弱.如:
–May I use your eraser?
– Certainly.But you must give it back to me soon.
②表示推测,意为“也许,可能”.如:
She may be at home.Let’s go to see him.
E.情态动词的否定式和疑问式:
①否定式:一般在can,may后面加not.如:
You can’t use the bike.
He may not be right.
②疑问式:将can,may提前即可.如:
I’m very tired.May I have a rest?
Can you help me (to) study maths?
