本文选自雅思听力Section 4，难度稍微有点大

场景背景介绍:本节开头部分并没有直接提到电影，而是提出一个问题：马在奔跑的时候四蹄是否有同时离地的时刻。后来一个摄影师把全过程用照相机拍下，然后又把所有的照片制作成连续的影像，终于揭开了谜团。从此，人们开始考虑是否能以此作为基础做出动态影像的影片。爱迪生成了这一想法的最终实施者。这种技术传到欧洲之后又得到了改进，例如设备变轻，加入声效等，这使得当时的电影制作难度大大增加。

Thomas Edison
Scotsman
Many believe that the story first began in America in 1877, when two friends were arguing over whether a horse ever had all four feet of hooves off the ground when it galloped. To settle the bet, a photographer was asked to photograph a horse galloping and the bet was settled because you could see that all the hooves were off the ground in some of the photos. What was even more interesting was that if the photos were shown in quick succession the horse looked like it was running - in other words 'moving pictures'. The person who became interested in taking the moving pictures to its next step was the famous American inventor Thomas Edison. Actually, he didn't do the work himself but rather asked a young Scotsman in his employ to design a system, which he did. Now this young fellow was clever because the first thing he did was study other systems - primitive as they were - of moving pictures and then put all the existing technologies together to make the first entire motion picture system.
