--I went to work on foot yesterday, though it was raining cats and dogs.
---You __________ a bus. You were likely to get a cold.
A．must have taken
B．would take
C．could take
D．should have taken
答案
答案：D
题目分析：考查情态动词的完成式，情态动词的完成式是对过去情况的推测或虚拟，因为第一句：--我们昨天去步行上班，虽然下着倾盆大雨。说明是指过去情况，排除BC，--must have done过去一定做了…,should have done过去本不该做而做了，所以选D，你本该乘车，你有可能感冒的。选D。
点评：使用“情态动词+have done”对过去的情况进行推测。如果是对现在情况的推测或虚拟，使用“情态动词+动词原形”；
