问题 Even if Thomas Edison hadn’t invented the electric light successfully, we ______electric light by now.

选项 A、would probably have
B、would have probably
C、would probably have had
D、would have probably had

答案C

解析 本题考查虚拟语气,是与过去事实相反(前面从句中过去完成时态的提示),所以主句用would/should have+动词的过去分词。题意为,即使托马斯·爱迪生原来没有成功地发明电灯,我们现在可能也用上电灯了。
