所以，必须要编写一个相当于内存缓冲器的处理程序来记录已读的内容，也同时需要编写一些代码进行提前读。

You'd have to write a handler to build what amounts to an in-memory buffer to keep up with what's already been read; then you'd need some code to read ahead as well.

那可能看起来不是很多，但如果车子能“读心”，他们能在高速中提前3.66米停止，那可以意味着是受惊还是受死的区别了。

That might not seem like much, but if cars could read minds, they could stop 12 feet sooner at highway speeds. Which could mean the difference between a scare and a smash.

A good, hygienic way of doing this is, not only do I not go in and change things except through a pre-defined method, I shouldn't read it other Cartesian than through a pre-defined method.

做这个的方式是，我不仅仅要通过提前定义好的方法,来改变数值,我还应该通过提前定义好的方法，来读这个值,我应该用。
