答案：B

题目分析：句意：看我现在的麻烦，要是我早听了你的建议就好了。If only后跟虚拟语气，对现在的虚拟用过去式，对过去的虚拟就用过去完成时，这里因为过去没有听建议，所以时对过去的虚拟，故选B。

点评：本题难度适中。虚拟语气是近几年高考的热点，虚拟语气的情况复杂，形式多样，需要考生牢记它们的不同的用法，再根据不同的语境分析句子应该用哪种情况的虚拟。

即学即练：You are late.If you ________ a little minutes earlier, you ________ him.

A. came; would meet       B. had come; would have met

C. came; would have met   D. were to come; would meet

解析：B。句意：考查虚拟语气的用法。由句意可知“没能遇到他”,表示对过去事实的虚拟，主句用would/could/should/might+过去分词，从句用过去完成时，故选B。
