【正确答案:B】
【译文】发明于本世紀初的真空电子管使得我们能够利用无线电波这种过去从未发现的能源,它为后来电视机的发明铺平了道路。
【解析】本句的主干是 The vacuum tube...gave ...and later opened ...;invented near the beginning of our century表达 invented...是过去分词短语作后置定语,对前面的tube做补充说明;an energy source 表达an...是同位语,对前面的radio waves做解释说明;never before( )表达never...是后置定语,修饰限定其前面的energy source,考虑到energy source与capture的“被动关系”,可首先排除C;再考虑到本句的谓语动词是并列的gave和opened,由此断定不会再出现新的动词,进而排除A和D (除非这两者前面有定语从句引导词that),综上,本题答案选B,即never before captured这一过去分词短语作前面an energy source的后置定语。
【点睛】过去分词短语作后置定语。
