I'm going to define a class, and in particular, what I'm going to do, is walk through what that says.

我们碰到了一个问题，这个问题就是，我们想要建立，一个抽象数据类型。

We're going to build up this taxonomy if you like, but the reason it's relevant is, associated with each one of those types is a set of operators that expect certain types of input in order to do their job.

我们将会建立这种分类，但是这相关的原因是，对于每种类型都有,和之对应的一个操作集,这个操作机对一些输入,做出规定的操作。

What we're saying is, in order to do computation, we want to describe recipes, we want to describe this sequence of steps built on some primitives, and we want to describe the flow of control that goes through those sequence of steps as we carry on So the last thing we need before we can start talking about real programming is, we need to describe those recipes.

我们在说，为了做计算，我们想描述一个方法，想描述建立在,相同基本类型上的步骤序列，而且我们想描述经过我们设计的,步骤的序列的，控制流程,因此我们开始谈论真正的编程之前,的最后一件事是，我们需要描述一下那些方法。

For now the way to think about this is, cp2 when I call that class definition, it goes off and allocates a specific spot in memory that corresponds to that instance.

这个语句所做的，就是建立了，这个类型的实例cp1和，这个类型的特定版本,现在你们可以这么认为。
