would,could,may,might,can的区别,请用简洁语言概括
would
1.将要,是will的过去形式,与动词原形构成过去将来时,用于第二、第三人称,例如:
He said he would come.他说他要来.
He would go on studying when he had graduated.
2.过去常常会 He would go fishing at that time.他那时经常去钓鱼.
3表意愿.例如:I would like.
比较may和might
1) 表示允许或请求;表示没有把握的推测;may 放在句首,表示祝愿.
May God bless you!
He might be at home.
注意:might 表示推测时,不表示时态.只是可能性比may 小.
2) 成语:may/might as well,后面接不带to 的不定式,意为"不妨".
If that is the case,we may as well try.
比较can 和could
can 可以(表示被允许)、能够(表示能力上的).
could意思和can一样,是can的过去时.另外,用于Could you please.的句型,表示建议别人做某事.
1)提出委婉的请求,(注意在回答中不可用could).
--- Could I have the television on?
--- Yes,you can./ No,you can't.
2)在否定,疑问句中表示推测或怀疑.
He couldn't be a bad man.
他不大可能是坏人.
