上一单元我们学习了英语中的大部分的情态动词,本单元我们会重点学习ought to 的用法,并小结一下表示推测的情态动词,及三个用法与情态动词的相同的短语had better,used to 和would rather 。

语法讲解ought to 的用法讲解1. 与众不同的ought toought to 是一个比较奇怪的情态动词,因为其他所有情态动词都后接动词原形,而ought to虽然也是后接动词原形,但却无意中构成了ought to do sth结构,其中的to do sth.便是一个典型的带to 不定式,并且ought to do sth 在用法上也是基本上将ought 与to do sth 分开使用——如构成疑问句,只需将ought 提前,而不是将ought to 提前;构成否定式时,是在ought后面加上not,而不是在ought to的后面加not。

如:Ought I to tell her the truth? 我应该把真实的情形告诉她吗?We ought to be careful,oughtn ' t we我们应该小心,对吧?Oughtn ' t he to see a doctor他是不是该去看医生?You oughtn ' t to stay out so la你不应当在外面待到这样晚。
