题目内容
Tony ____ the invitation, otherwise he would have attended your birthday party.
| A．couldn’t have received | B．mustn’t have received |
| C．needn’t have received | D．shouldn’t have received |
A
解析试题分析：句意：Tony不可能接受邀请的，否则他就会参加你的生日聚会了。根据otherwise he would have attended your birthday party.可知这里是否定推测，couldn’t have done过去不可能做了…，must表示推测的时候，用肯定，所以B不对，needn’t have done过去本不必做而做了，shouldn’t have done过去本不应该做而做了，选A。
考点：考查情态动词的完成式
