题型：不详难度：来源：
No wonder you caught a cold. You________have gone out last night without a coat.| A．shouldn’t | B．mustn’t | | C．couldn’t | D．mightn’t |
|
答案
| A |
解析
| 考查虚拟语气。句意：怪不得你会感冒。你昨晚不该没穿外套就出去。“shouldn’t+have+done”表示本来不应该做某事，而实际做了；“mustn’t +have+done”表示对过去事情的否定推测，译成“一定没有做过某事”； “couldn’t +have+done”表示对过去事情的假设，意思是本来不能够做某事而做了；“mightn’t +have+done”表示对过去已经发生的事情的推测，might与may意思相同，但可能性更小。结合语境可知选A。 |
