这样你就可以知道，假设，噢，我真的懂这个，但是我的速度有点慢，或许我需要在练习这个类型的题目上,多花一点时间,这样我就可以提高自己的速度,可以全部做完,在考试规定的时间内。

It's one that we'll take up in greater detail, though, when we get to the book of Deuteronomy, where it is stressed to a greater degree than it is in Exodus, but for now, we can accept Levenson's claim that Sinai represents an intersection of law and love, because of the use of the suzerainty model.

So here is the simplest program which is perhaps an ironic statement that you can implement with this language called C. So it takes a few lines of code to actually get something up and running and as you'll recall last Friday, I didn't even get this up and running because part of the process of writing a program is to one, write it.

让我们回到这个最简单的程序,你们也许觉得啼笑皆非，这么简单的例子,用C语言写出来就可以了嘛，的确只需要几行代码,就可以让这个程序跑起来,就像上周五的那样，我之所以没让它跑起来,因为编程步骤之一,就是“写“
