翻译When you watch a movie in the cinema, you may wonde
When you watch a movie in the cinema, you may wonder “how moving picture” is made and where the voice, noise and music come form. Now is the answer.
  In the modern times, the middle part of a cinema film has lots of small photographs, each one of which is different from the one before it. Each photograph is brought in front of a strong light, and there it stops for a very small part of a second. This photograph, therefore, appear on the screen, and we see it. Then the light is covered and next photograph is move to the position in front the strong light. Meanwhile(同时), the metal cover turns away from the light.

答案
当你在电影院看电影的时候,你也许会好奇:这些运动着的画面是怎么形成的,这些声音,杂音,音乐来自哪里.现在就看看答案吧
现代社会里,电影胶片是有许多的小图片组成,并且每一张图片都和前面的一张不同,每一张图片都要讲过一束强光并停留几秒,由此这张图片就会停留在荧幕上了,我们就可以看见了,然后这束光被金属封盖盖住后下一张图片就取代了前一张图片的位置,同时金属封盖再移开,由此第二章图片就投在了荧幕上,一遍又一遍,每一分钟24次,我们以为我们是在看荧幕上运动着的图片,实际上我们看的就是电影了. "运动的图片(即电影)"实际上由许多的比特(二进制的信息单位)组成,我们每个小时可看到86400张不同的图片,但是没有一个是运动着的.
声音,杂音和音乐则是在电影胶片另一边刻录的,i这些刻录就像奇怪形状的标记一样,胶片的另一边通过另外一束光,光的射线在通过胶片的时候随着这些标记变化而变化,在胶片制作的时候,这些以声音和人发出的声音,以及镜头前的事件的为元素的标记已经合成了,你可以把这些标记看作是:印刷了的声音
