Question

---I’m sorry. I _________ at you the other day.
---Forget it. It was a bit out of control myself.

A．shouldn’t shout	B．shouldn’t have shouted
C．mustn’t shout	D．mustn’t have shouted

Answer 1

B

试题分析：句意是：---对不起，前几天我不应该对你大嚷大叫。--没关系，我有点失控。前句中有明显的时间状语the other day (几天前)，事情发生在过去。可以排除AC。“shouldn’t have done”过去本不应该做而做了，must have done过去一定做了…，所以选B。
