三、语法新课讲解
情态动词should、ought to
一、should的用法:
should用做情态动词,无时态和人称变化,后面跟动词原形。其否定式为:should not(shouldn't)
1. 表示“义务或责任”,意思是“应该”。
e.g. We should keep our promise. 我们应该遵守诺言。
You shouldn't be so careless. 你不应如此粗心大意。
【友情提示】should后面跟“have+过去分词”结构,其肯定句表示过去应该做而未做的事,其否定句则表示过去不该做但做了的事情。
e.g. You should have started 5 minutes earlier.
你应该早5分钟动身。(却没早动身)
I should have thought of that. 这一点我是应当想到的。
(却没想到)
She looks very ill. She should have stayed at home.
她看样子病很严重,她本应待在家里。(却没待在家里)
You should not have gone back to work without the doctor's permission.
你不应该未经医生许可就回去工作。(却去工作了)
2. 表示可能性、推测、估计,意思是“可能”、“该”。
e.g. She should be home by now, I think.
我想,她现在可能(该)到家了。
It's two o’clock, the football game should begin soon.
已经两点钟了,足球比赛不久就该开始了。
3. 表示说话人用委婉、谦虚的语气提出意见、请求或建议,意思是“可”、“倒是”、“想”等。
e.g. I should say it would be better to try it again
我以为可再试试。(提出建议)

二、ought to的用法:
ought无时态和人称变化,后面跟(带to的)动词不定式,其疑问式为:Ought I/you to…?其否定式为:
ought not to…
1. 表示有义务必须做某事,意思是“应该”;其语气比should强,带有责备或督促的含义。
e.g. You ought to be punctual. 你应该守时。
--Ought he to do it at once 他应当立刻就做吗?
--Yes, he ought(to). 是的,他应当立刻就做。
They ought to go tomorrow. 他们应该明天去。

She said such a thing ought not to be allowed to happen.
她说这样的事不应当允许发生。
【友情提示】ought to后面跟“have+过去分词”结构,表示对过去该做而未做之事的责难、后悔或遗憾的心情。
e.g. You ought to have helped her.
你本该帮助她的。(却没有帮助她)
He ought to have returned these books to the library last week.
他上星期就应该把这些书还给图书馆。(却没有还书)
I ought not to have done it. 我本不该做这件事。(却做了)
2. 表示非常可能的事,意思是“一定会”、“该……”。
