Do you know by whom the light bulb was invented? by whom是怎么理解的 再举些例子吧! 急!
答
by whom是was invented的动作主体状语，这个whom就是发出invented动作的人，只不过不知道的时候用whom这个疑问代词，相当于数学里的X。又如：The window was broken by a boy.变为疑问句是By whom the window was broken? The piano was damaged by a visitor.变为By whom the piano was damaged?

Do you know by whom the light bulb was invented? 你知道是谁发明的电灯泡么？
