①ought是情态动词,没有人称和数的变化,后跟带to的不定式,表示责任或义务,与should意思相近。 其否定式为 ought not to do/oughtn't to do 其疑问式为 ought + 主语 + to do? 其被动式为 ought to be done ②ought跟不定式的完成式表示过去的行为,往往含有责怪的意味。 肯定式表示过去本该做某事却没有做: Tom ought to have finished his composition last Sunday. 汤姆本该上星期天就写完作文。 否定式表示过去本不该做某事却做了: You ought not to have allowed the girls to go out at night. 你本不该让这些女孩深夜出去。
