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.每个公民都应该遵守法律。
You ought to have told me that yesterday.
你昨天就应该把这件事情告诉我了。
Sam ought to have known how dangerous it was.
萨姆本该知道那事多危险。

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.你应该按他说的去做。(应该、义务)
You really shouldn’t tell such lies.你实在不该说这种谎话。(责备)
He should have known how dangerous it was.他本该知道那是多么危险。(责备)
You shouldn’t have blamed her so seriously;she is still a child.你不应该这么严厉地指责她，她还是个孩子。(责备)
Why should I be angry with you?我怎么会生你的气呢？(意外)
I didn’t expect that you should have finished the work so soon.我没想到你竟会这么快就完成了工作。(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.你应当帮助你同学学习化学。
You are his father.You ought to bring up him.你是他的爸爸，你应当抚育他。
(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.
你必须服从学校的规则。
I must go now.我现在得走了。
You have to pass a special exam to get into the school.
你要上那所学校得通过一次特别的考试。
My father is ill.I have to stay at home to take care of him.
我父亲病了，我必须(不得不)留在家里照顾他。
You mustn’t go.= Don’t go.别走。
They have had to wash the wall carefully.
他们已不得不把墙壁仔细清洗。
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.
今晚我只好熬夜批试卷。
The man said that he must do it whether his parents agreed or not.
那个人说不管父母同意不同意他必须做这事。
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.
所有公司的人们必须在晚会上跳华尔兹舞。
