B
【解析】
试题分析：考查虚拟语气：句意：如果我们走另外一条路，就有可能及时赶上开会。If非真实条件句是和过去相反的，用过去完成时，主句是would/might/should/could have done。选B。
考点：考查条件句的虚拟语气
点评：if的虚拟语气非常重要，简要概括如下：1、表示与现在事实相反的情况，从句：If主语+过去时(Be动词用were)；主句：主语+should/would/could/might+do： 2、表示与过去事实相反的情况，从句：If主语+had+done；主句：主语+should/would/could/might+have done 3、表示对将来情况的主观推测，从句：①if+主语+were to do②if+主语+should+do ③if+主语+did（动词过去式）/were ；主句：主语+should/would/could/might+do
