Question

   no modern telecommunications, we would have to wait for weeks to get news from around the world.

A．Were there

B．Had there been

C．If there are

D．If there have been

Answer 1

A

解析试题分析：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”。
考点：考查虚拟条件句。
