三、语法解读
ought to,must,have to,should情态动词的用法区别：
1.ought to
要点提示：
ought to 表示“应该”。

典型例句：
Every citizen ought to obey the law.
You ought to have told me that yesterday.
Sam ought to have known how dangerous it was.
相关链接：
ought to表示推测时，与must表示推测稍有不同。

例如:
He must be home by now.(断定他已经到家)
He ought to be home by now.(不十分肯定)
2.should/ought to
要点提示：
should与ought to意义相同。

（1）表示应该，义务。

(2)对已经发生的情况表示责备。

结构为should(或ought to)+have+过去分词。

(3)表示惊讶、意外、难以置信，常与why,who,how等连用。

对现在情况表示惊奇用“should+动词原形”;对过去情况表示惊奇用“should +have+过去分词”。

典型例句：
You should do as he says. (应该、义务)
You really shouldn’t tell such lies. (责备)
He should have known how dangerous it was. (责备)
You shouldn’t have blamed her so seriously;she is still a child. (责备) Why should I be angry with you? (意外)
I didn’t expect that you should ha ve finished the work so soon. (惊讶)
相关链接:
(1)should和have to用法也略有不同:表示自己的主观看法，语气重，含有“按道理应该……”之意，用should;如果要反映客观情况以及法律义务和规定时一般用ought to。

例如:
You should help your classmate with his chemistry.
You are his father.You ought to bring up him.。

(2)must和 have to 的区别
① must含说话者的强烈的决心(表示主观的看法)。

have to则表示外力环境或习惯所使然(即表示客观的必要，作“不得不”讲)。

例如:
You must obey the rule of your school.
I must go now.
You have to pass a special exam to get into the school.
My father is ill.I have to stay at home to take care of him.
You mus tn’t go.= Don’t go.
They have had to wash the wall carefully.
②have to可用于较多的时态，而must一般只有现在时，只是在间接引语中用来表示过去时。

例如:
I had got to go and see her off at the railway station.
那时我只得去火车站为她送行。

I will have to stay up late tonight to mark the paper.
The man said that he must do it whether his parents agreed or not.
③在公告或者文件中，用must 而不用have to。

例如:
All the people in the firm must dance the waltz at the party.
