哇,这是个好问题! Ought to是should的替代表达,通常用于给出建议的情况。 Have to可以说是可以替代must的表达式。 Have to用来告诉别人必须做某事,不做会有后果!例子: You ought to send her a card to say thank you for the gift. (对于礼物,您需要给她寄一张感谢卡。)示例: You have to send her a card to say thank you for the gift. If you don't, you will lose your job. (对于礼物,你必须给她寄一张感谢卡,否则你会被解雇。)
