单选题 If he ______ my advice, he could not have been so miserable.
  • A) listen to
  • B) had listened to
  • C) would have listened to
  • D) should listen to


【正确答案】 B
【答案解析】[解析] 从主句谓语的形式可以判断出该句是与过去事实相反的虚拟条件句，因此从句的谓语应用had done的形式，而主句的谓语则应使用could/would/might/should have done的形式。例如：If you had worked hard，you could have passed the exam．(如果你努力学习，就会通过考试了。)
