Ifyou________yesterday，you________withyourmothernow.A.setoff;wouldtalkB.

If you ________ yesterday，you ________ with your mother now.A.set off; would talkB.had set off; would be talkingC.set off; would have talkedD.had set off; would talk

D解析试题分析：句意：如果昨天你动身走了，那么你现在就能和你的妈妈说话了。这是错综虚拟语气，从句是对过去的虚拟，所以用过去完成时，主句是对现在的虚拟，所以用would+动词原形。考点：考查虚拟语气的用法。点评：本题较难。错综虚拟对于学生来说是难点，虚拟语气是高中阶段的重要语法项目，需要考生牢记各种情况的虚拟语气的谓语动词的形式，并要有分析理解语境的能力。即学即练：If you _______to the teacher carefully yesterday, you _______ how to do the exercise now. A．listened; would know B．had listened; would be knowingC．listened; would have known D．had listened; would know解析：D。句意：如果你昨天认真听了老师的讲话，你现在就知道如何做这道题了。
