The boss has given everyone a special holiday, so we ____ go to work tomorrow. A. can’t B. mustn’t C. needn’t D. shouldn’t 【点拨】考查情态动词。根据题意, 可知这 里表示“没有必要”, 故只能选C项。

You __________________________ should / ought to have made the decision a week ago. 你应该在一周前就做决定。 I ___________________ shouldn’t have made such a foolish mistake. 我不应该犯这样愚蠢的错误。 多数情况下，ought to可与should互换使用。 ought to的反意疑问句用shouldn’t替代。
