B

【解析】

试题分析：考查if非真实条件句的虚拟语气。根据if条件句的虚拟语气，从句中if I were you可知是与现在事实相反的虚拟。本题从句用were那么主句就用would /could /should /might+have done结构 ；B符合if条件句的虚拟语气中主句的用法。故选B。注意：在非真实条件从句中，与现在事实相反的虚拟，不管主语是第几人称，be动词永远只能是were。

【名师点睛】

If 条件句的虚拟语气有三种情况：

1.与现在事实相反： 从句用过去时（be动词用were的形式），主句用would/could/should/might+动词原形

2.与过去事实相反：从句用过去完成时，主句用would/could/should/might+ have done

3.与将来事实相反: 从句用过去时（be动词用were的形式）/should do/were to do，主句用would/could/should/might+动词原形

虚拟条件句中常省略连词“if ”，而把系动词，助动词，情态动词提到主语前。做这类题，要根据已经给出的主句或从句的谓语动词来推出是与过去，现在还是将来事实相反，然后再得出答案。
