试题分析：对现在情况的虚拟，条件句中用一般过去时，主句用“ would/ should/ might/ could +动词原形。虚拟条件句中有had, should, were时，可以将if去掉，然后把had, should, were提到主语前面。所以选A。句意：如果没有现代的通信，我们将会等上几周的时间才能得到来自世界的新闻。
【知识拓展】
虚拟条件句的基本类型与结构。一、与现在事实相反。若与现在事实相反，虚拟语气的条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。二、与过去事实相反。若与过去事实相反，虚拟语气的条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, could, might)+have+过去分词”。三、与将来事实相反。若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。
