阅读下列材料，回答问题。

材料一　贾谊在《过秦论》中说：“秦并海内，兼诸侯，南面称帝，以养四海，天下之士斐然乡(向)风，若是者何也？曰：近古之无王者久矣。周室卑微，五霸既殁，令不行于天下，是以诸侯力政，强侵弱，众暴寡，兵革不休，士民罢敝。今秦南面而王天下，是上有天子也。既元元之民冀得安其性命，莫不虚心而仰上，当此之时，专威定功，安危之本在于此矣。”

材料二　秦王嬴政初并天下，对丞相、御史等大臣说：“寡人以眇眇之身，兴兵诛暴乱，赖宗庙之灵，六王咸伏其辜，天下大定。今名号不更，无以称成功，传后世。”群臣提出：“古有天皇，有地皇，有泰皇，泰皇最贵”，应上尊号为“泰皇”。嬴政并不以此为满足，决定从“三皇”中取一个“皇”字，又取上古“五帝”中的“帝”字，合成“皇帝”，作为自己的名号。

材料三　秦朝政府的组织(下图)
