Why? Because that block identifies a set of things that I'm going to do if the test is true.

为什么呢？这是因为这一块指令,指定了一系列的要进行的操作,如果测试为真的话。

It has a test in it, which is that while, while something is true, do something, but I want to keep doing it.

也有个测试在里面，也就是那个当，当一件事情为真的时候，做一些操作，但是我想一直进行判断。

If I come into this code, I'm going to check this branch first, if it's not true, ah, there's a return at the end of that branch. If it is true, I do that, and then I've got a second test. If it's true, return I return, otherwise a return.

但是如果我们看看这里,如果我看这段程序,我会先检查这一部分，如果它是假的，啊，这部分分支结尾有一个。

All right, if this is purely a test of, if this is true do this otherwise I don't care, I don't need the ELSE clause in there to identify it. All right?

好，如果这真是一个测验，用来测试如果是真的那么进行一些操作,否则的话我不在乎，那么我不需要ELSE语句,来进行声明了对不对？

So what's going to happen here? If I'm inside this FOR, OK, and I'm running around, if I ever hit a place where this test is true, I'm going to execute that return, return that return returns from the entire procedure. OK? So the return comes back from the procedure.

那么这里发生了什么呢？,如果我是在这个for循环里面，我正在运行，如果我运行到test的值为真的地方，我就会执行,这个return将会返回整个程序的值,明白了吗？所以它将会从整个程序中返回值。
