As it turned out to be a small house party, we __________ so formally.| A．needn’t dress up | B．shouldn’t dress up | | C．were not necessary to dress up | D．needn’t have dressed up |
|
答案
| D |
解析
试题分析：考查虚拟语气。根据As it turned out to be中的过去时，说明这是与过去的事实相反的虚拟语气，故使用“情态动词+have done”的形式。Needn’t have done本不需要做某事实际上却做了。句意：正如结果所显示的那样，这是一个小型的家庭聚会，我们本不必要穿得如此的正式的。故D正确。
点评：与过去的事实相反的虚拟语气，故使用“情态动词+have done”的形式。Needn’t have done本不需要做某事实际上却做了。 |
