1、.ought to“应该;应当”,与should的用法类似,其没有人称、数和时态的变化。他可以表示“有责任或义务”而做某事。Ought to表达的语气比should强烈,在表示推测时,意为“按常理说应该……”,暗示有很大的可能性,有时可译为“建议或劝告”。
2、同should用法一样,在肯定句中,当ought to后跟完成时,此时意为“过去本应该做某事而未做”;在否定句中意为“过去不该做某事却做了。”
3、Ought to的一般疑问句形式是将ought提到句首。例如:
She ought to leave now.---->Ought she to leave now?
她现在应该离开了。---->她现在应该离开了吗?
4、ought to的反意疑问句:
We ought to study hard, oughtn't we/shouldn't we?
我们应该刻苦学习,是吗?
5、ought to与should一般来说,两者可以互换,只是ought to的语气略强。另外,表示出于法令规则、行为准则、道德责任等客观情况而“应该”做某事,通常用ought to;若用should则含有个人意见,强调主观看法。

3、the company ought todo something about the poor service.
