As it turned out to be the most important meeting in the year, you ____ so casually. | A．Shouldn’t dress up | B．shouldn’t have dressed up | | C．needn"t have dressed up | D．couldn’t dress up |
|
答案
| B |
解析
试题分析:考查情态动词。从语境可知此处是讲述过去的事情，所以应该用情态动词+have done，故排除A，D选项，needn’t have dressed up“本来没必要这样穿戴打扮”，而shouldn’t have dressed up “本来不应该这样穿戴打扮”，根据语境判断B选项正确。句意：这次会议结果成了一年中最重要的一次会议，你真不应该穿的那样随便。 |
