选择题
- - How dangerous it was!
- - Yes, but for the passer - by' s quick action, the child _____．
A．was drowned
B．could have been drowned
C．had been drowned
D．should have drowned
答案
答案：B
题目分析：考查虚拟语气。句义：多危险啊！是，要不是过路人的快速行动，那个孩子可能会被淹死。把握关键词but for，是对过去的虚拟，主句当然是过去的虚拟：would/could/should + have done,在根据句意孩子和淹死之间是被动关系，所以B正确。
