课堂上的“成功”需要学生掌握这个抽象的代码。

"Success" in the classroom requires a student to master this abstract code.

实现是抽象的代码级别。

Implementation is the code level of abstraction.

在这种情况下，您仅需修改抽象类，代码将完成编译。

In this case, you can modify just the abstract class and the code will compile.

I want to just use it, I shouldn't have to worry about what variables I use inside of it, I have shouldn't have to worry about where that is in the code, I should be able to just abstract it away. And that's what we want to add today, are those two things.

我只是想使用它,我不用考虑我在这段代码中,使用的是什么变量,我完全不用考虑代码的内容,只要抽象就好,我们今天想补充的内容就是这两点。

or at least one mechanism, I shouldn't say -- the only one-- one mechanism for doing that is going to be to add functions is that it's going to provide both of these things, so the first thing it's going to do is, it's going to let us break up into modules.

我们处理这些的机制--至少一种机制,我不会说只有一种,一种机制是在我们的语言中增加函数,函数的关键是它要提供分解和抽象,所以第一件要做的事，就是将代码分解为模块。
