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
答案:A
题目分析: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”。
