问题描述:

The electricity () in our rooms is one of his greatest inventions.
A.to shine B.shine C.shining D.shone
为什么选c不选A
Today,with great trains ______ on electricity,we can travel much faster.
A.to run B.ran C.run D.running
为什么选d不选a
With our homes and the streets of town and village () by electric lamps
A.to light B.light C.lit D.lighting
为什么选c

这三句都是以非谓语组成定语来修饰前面的名词,
其中前两句用现在分词:
1) shining in our room 修饰electricy
2) running on electricity 修饰 trains
是因为都是 “主动” 语态表达
1)电(灯)照亮,而不是我们的房间照亮;
2)火车(靠电作为动力)奔驰,而不是电在奔驰
最后一句用过去分词 lit,因为是以“被动”语态表达 ”村里的大街【被】电灯照亮”为什么不用to do呢不定式在这几句中不合适,因为 to do 使用时隐含着 ” 尚未,但将会如此进行或发生 “的动作或行为,而这些句子中用分词都是说明现状。
