Strictly speaking, our next stop on the walk through time should have been a 3.4-million-year-old site called Maka, which had yielded a jaw and some other remains of Australopithecus afarensis.

严格说来，我们穿越时光之旅的下一站将停留在已有340万年的马卡（Maka）遗址，此地曾出土了南方古猿阿法种（Australopithecus afarensis）的一块颌骨以及其他一些遗骸。

That is basically saying, given some collection of data, I want to have again a looping mechanism, where now my process is, walk through this, the collection one element at a time. And for that, we have a particular construct, called a FOR loop.

现在我的过程就是,通过一个个访问这个集合中,的元素的方式，来遍历这个集合,为了达到这个目的，我们有一个特定的结构，成为FOR循环。
