2、ind, please inform us as soon as possible.AShouldBWereCWouldDHad【答案】A【解析】【分析】【详解】考查虚拟语气。句意：我们将对我们的计划做最后决定。如果你改变主意，请尽快通知我们。根据语境，此处用虚拟语气，表示与将来相反，从句用should+动词原形，省略if，should提前，陈述句是：If you should change your mind。故选A。【点睛】虚拟语气中的倒装当虚拟条件句中含有 were，had，should时，可以将if省略，然后将 were，had，should，移至句首：1）If he should f
3、ail, he would kill himself.Should he fail, he would kill himself.万一失败，他就会自杀。2）If I were you, I would do it at once.Were I you, I would do it at once.假若我是你，我就会马上做。要是我能做此事，我一定会做。3）If he had seen you yesterday, he would have asked you about it.Had he seen you yesterday, he would have asked you about it
4、.他昨天要是看到了你，他就会问你这事了。该小题属于上述的第一种情况。should作为情态动词，有一种特殊的用法：在虚拟条件状语从句中表示与将来事实相反的虚拟语气，可以把should放在句首，即主语前，从而省略从属连词if。原来的表述为：If you should change your mind。故选A。3_ you disturb me now?
