电视画面
电视画面欺骗你的眼睛,当你看一幅图时,你的大脑停留图片十分之一秒,然后你继续看,所以当你的大脑一秒停留十多幅图片时,就是把图片放一起作为移动的画面。你可以画同一个人的许多张图片,自己观察一下,这个人在笔记本的每一页上,然后你迅速翻页,这个人好像是移动的。
电视画面通过屏幕使用一系列的线条,线条改变图片每秒很多次并出现移动的图片,我们称这种电视为"模拟电视"。
现在有数字电视,没有线条,声音和图片都是数字的,当数字在数字电视上改变,唯一不同是旧图片、新图片之间的改变,所以它改变很快且图片声音很好。

2 No, I don't. Watching TV is a good way for people to relax themselves
