问题 I was really anxious about you. You ______ home without a word.

选项 A、mustn’t leave
B、shouldn’t have left
C、couldn’t leave
D、needn’t leave

答案B

解析 该题考查“情态动词+have done”表“责备”的用法。shouldn’t have done和ought not to have done表示“本不该做却做了”,couldn’t have done表示“过去不可能作过某事”,mustn’t do表示“现在肯定没做某事”,needn’t do,表示“不需要做某事”。故选B。
