五、might的用法
might表示的可能性太小,没有足够的说服力去职责别人。
can, could 之间的区别,和 may,might 之间的区别在于,虚拟句和过去时态用后者,表示的可能性比原词小,但大部分时候2者可以互换,不会产生歧义或者对表述造成干扰。
六、should的用法
1.should 作为助动词 shall 的过去式,可以在间接引语中与第一人称主语搭配,表示过去将来时间。
2.should 作为情态动词,通常用来表示现在或将来的责任或义务,译作“应该”、“应当”,这时它可以和 ought to, be supposed to 互换使用。例如:
You should (= are supposed to ) complete your test in time.
你们应该按时做完你们的实验。

Would you like a cup of tea?
您愿意喝杯茶吗?
2.主语+would like to~
表示“想要……”的意思上,与…want to~意思一 样,但用此句型较客气。
I want to ask you a question.
3.最基本的虚拟语气句型:
主句用would/ should/ could/ might +动词原形。
八。ought to的用法
ought to 是一个可以加上to 的情态动词其意思与should是一样的,但是ought to 不能用于虚拟语气中表示推测,而should可以
ought to与should意思接近,大多数情况下二者可以互换,但是should谈的是自己的主观看法,ought to则更多反映客观情况,在谈到法律、义务和规定时使用。
如: We should/ought to help each other and learn from each other in our work.
She is your mother, so you ought to support her.
We ought to go and see Mary tomorrow, but I don’t think we will.
(无论是哪个情态动词,后面肯定加动词原形。)

(3)Can / Could he have gotten the book?

注:情态动词 should /ought to表推测时,意为“想必会,理应……”但与“have +过去分词”连用时,则又可构成虚拟语气意为“本应该做某事却没做”。例如:
(4)It’s seven o’clock. Jack should/ought to be here at any moment.
