【解析】考查情态动词用法。没有mustn’t have done 的结构,故排除A。shouldn’t have done 本不应该做某事,实际上却做了;can’t/couldn’t have done不可能做了某事,表示对过去肯定的推测;句意:房间乱七八糟。不可能打扫了。故B正确。
考点:考查情态动词用法。
点评:情态动词+have done ,表示对过去的虚拟或推测。记住这些结构的意思:shouldn’t have done 本不应该做某事,实际上却做了;needn’t have done本不需要做某事,实际上却做了。can’t/couldn’ t have done不可能做了某事,

When the waitress came over, I asked her if she knew them. She said she did. She said it was the elderly man’s birthday today. On hearing this, I wanted to do something for them, so I told the 7 that I wanted to buy them the lunch and gave her the money.
Some time later, the elderly couple came over to 8 us. They were so excited that someone had bought them lunch. It was really a big 9 for them. They said that they had been a little 10 because their own son and daughter seemed to have 11 the old man’s birthday. But they were really cheered up by my 12 .
