Question

—Did you visit the museum today?
—No. We _____ it, but we spent too much time shopping.

A．could have visited	B．must have visited
C．could visit	D．must visit

Answer 1

A

解析试题分析：句意：--你们今天参观博物馆了吗？--没有，我们本能参观的，可是我们都把时间用在购物上了。根据这里动词spent可知，这件事已经发生，对过去的推测只能用情态动词+have done，故排除CD；
must have done表示过去一定做过某事；could have done表示过去本来能够做某事而未做成。根据句意故选A。
考点：考查情态动词的用法。
点评：本题难度适中。情态动词是高中阶段的重难点之一，需要考生熟记它们的用法，在各类考试中经常出现，情态动词的完成式主要用于表示对过去情况进行推测或责备也是高考常考的内容。
即学即练：--- I stayed at a hotel while in New York. --- Oh, did you?You ___ with Barbara.
A. could have stay  B. could stay  C. would stay  D. must have stay
解析：A。本句是一个含蓄虚拟条件句，意思是：If you hadn’t stay at a hotel while in New York, you could have stayed with Barbara. 表达了与过去事实相反的情况。
