摘要：90．我认为在一个星期之内完成这么难的工作并非易事. B)把下面短文中的划线部分译成汉语. (91)Thomas Edison was perhaps the greatest inventor the world has ever known．Without his invention. people may not have had lights.films and other things．(92)But this clever man had very little schooling． Edison began to make a talking machine in 1877．(93)At first he used paper with holes to make a sound．He worked for months on this idea．At last he found how to record a person's voice．(94)But the first machine was very simple and the voice was only one type and not clear．Then he spent another long time on it．He changed some parts and he added some new ones to the talking machine．This time the voice could be played and the voice was also very clear．(95)After the Second World War others used his method to record music and songs．Then came the tape recorder．It is much easier to record the voice．How great Edison was．
