It's a way of breaking the code up into modules. Modules that makes sense on their own. Modules that we can reuse in multiple places. Modules that, if you like, Isolate components of the process.

能将代码分解为模块,模块能够独自运作,我们能在很多地方再利用这些模块,如果你喜欢的话，模块可以被看作是过程独立的组成部分。

I'd really like to have that modularity that says, I'm only going to get access to the values, not by calling their names, but by calling some specific method to get access to their names.

这样我们就丢掉了代码的模块化,我很希望代码有这样的模块化：,我访问变量的值，不是通过直接调用它们的名字，而是通过调用某个可以,访问这些变量名的方法来访问。

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。

What we're really getting at is the idea of saying I want to have a way of grouping together information into units that make sense. So I can go back to one of those topics we had at the beginning, which is the idea of abstraction, that I can create one of those units as a simple entity, bury away the details and write really modular code.

组合成为有意义的单元,那么这就让我们回到,一开始讲的话题之一了,这就是抽象的概念,也就是我可以以一个简单的，实体的形式创建这样的一个单元，把具体实现隐藏然后写一些,真正模块化的代码,我们在以后的课程中。
