Most people have no concept of how an automatic transmission works, yet they know how to drive a car. You don't have to study physics to understand the laws of motion to drive a car. You don't have to understand any of this stuff to use Macintosh.
大多数人对自动变速器的工作原理一无所知，但他们知道如何开车。你不需要学习物理就能理解开车时的运动规律。在使用麦金塔电脑时，你不需要了解这些东西。
