一)、非推测性用法1. 词义及用法：独门独户型
must必须
ought to 本该一心两用型
deed需要
dare敢区分1
基本用法：could，would，might，should是四个独立的情态动词，
只有在直接引语变成间接引语时作为will，can , shall, may的过去时代用一下Shall we begin now?He asked if we should begin now?2.同义区分区分2 ：
社交口语中，同义情况下，would, could , should, might比原型更委婉、礼貌。
你今晚来吗？
你能帮我吗？
?
你或许能帮我个忙吧?
Would you come tonight？
Could you help me?
You might do me a favor? 一般上指“自己允许别人做某事”（may较正式）
can
may
同义，语气较委婉
could
Might
区分3—请求许可--Can/May/ Could/Might I use your dictionary?
--Yes, you can.
(No, I am afraid not/Yes, please./ Thanks)May 引导问句，
肯定回答，Yes, of course./ Yes, certainly./Sure
否定回答：No, you mustn’t（不准）. No, you needn’t. No, you can’t.
Must 引导问句，（must与have to 意思大致相同）
肯定回答:must
否定回答：Needn’t/ Don’t have to. 区分4—建议请求Will 多用第二人称疑问句；
Would（will的过去式，委婉）
Shall 多用第一人称疑问；
Should (间接引语)；
Can/may 多用第一人称疑问，
“求得认可” you open the window please? I feel a bit hot here.
you like to see the film?
we see the film together?
I sing a song for you ?Will WouldShallCan/May-- Shall we talk?　　
-- Shall he come to see you ?
No, you_____ . 否定回答
May ------ can’t, mustn’t
Shall, must----- needn’t, don’t have to（没必要）needn’t注意添加否定词的含义mustn’t 不准, 禁止
needn’t 没必要 ( = don’t have to )
may not 不可以;
shouldn’t 不应该 ( = ought not to )
补充（1）would like意为“想要，愿意”，相当于want，但比want语气委婉。
① would like sth. 想要某物
I would like some tea.
② would like (sb) to do sth. 想要干某事
I would like to go with you.
(2) Would you like to do sth? “你愿意干某事吗？”
Yes, I’d like/love to;
Sorry, I am afraid not.再说明原因。
牢记搭配宁愿做
would rather do…
would prefer to do...
最好做
had better do...区别5 半情态动词
Need需要
(sb.) need to do
(sth.) need to be done
(sth.) need doing
Dare敢;
