may和might的区别及用法

Question

如题所述

Answer 1

一、表示允许　　
其意为“可以”.表示请求允许(即请求别人允许自己做某事),两者都可用,只是 might 表示的语气较委婉(但并不表示过去)；表示给予允许(即自己允许别人做某事),通常要用may而不用might.如：
May (Might) I come round in the morning?我早上来可以吗?
“May I take this book out?” “Yes,you may.” “我可以把这书带走吗?”“唔,可以.”(由于答语是表示给予允许,可用 may,但不能用 might)　　
You may take my dictionary as long as you don’t keep it too long.只要使用时间不太长,你可以把我的词典拿去.(不用might)　　
二、表示推测　　
may 和 might 均可表示推测,意为“可能”.此时 might 并非表示过去,只是比may 语气更不确定,表示的可能性更小.两者均可用于肯定句和否定句,但用于疑问句时,may 通常不用于句首,而 might 有时可用于疑问句的句首.如：
He may (might) be in his office now.他现在说不定在办公室里.
You may (might) be able to persuade him.你也许能说服他.
Might it rain tonight?今晚会下雨吗?
要表示对过去的情况进行推测,不能用“might+动词原形”,必须用“may / might+have+过去分词”结构.如：
I may have hurt your feelings but that was certainly not my intention.我或许伤害了你的感情,但那绝非我的意图.
There may (might) have been someone waiting outside.可能曾有人在外面等候.
另外,“might+have+过去分词”还可表示过去可能发生而实际上却并没发生的事(此时的might不能换成may).如：
In other circumstances,I might have agreed.在其他情况下我可能就会同意的.
I might have guessed he’d fail to read the instructions.我本来早该知道他不会看说明书的.

Answer 2

情态动词may和might有哪些不同

Answer 3

may是情态动词，表示“可能”或“可以”，后接动词原形，构成谓语动词。它有两种形式，原形为may，过去式为might。
may的基本含义是表示“可能”，即不很肯定的推测，或者表示“可以”，即允许做某事的意思。指现在时，可以用may，may还可以表示祝愿，may一般不用于疑问句，用在疑问句中时，表示询问情况，含不肯定的语气，例如：
He may be right.
He may be watching TV.
May I leave the table?
May I never see such a sight again!
May you succeed!
Well, and who may you be?
How old may she be?
It may have rained yesterday. The ground was wet.
如果表示过去可能或可以做某事，就用may的过去式might，might用于疑问句的时候，也可以表示询问情况，或用在间接问句中。might常用在主句为过去式的名词性从句中，如果用在独立句中，语气比may更不确定，把握性更小。如：
He said that it might be true.
He asked whether he might leave the table.
Bill asked who she might be.
The keys might have fallen out of your pocket.

我可以进来吗?--Sure ./ Certainly ..请进.
--Please don't ..请不要进来.
--No ,you mustn't .不行.
