45 THE FAR NORTH

CHAPTER 45 THE FAR NORTH The far north was a place of extremes. Entire seas froze over and then melted with the changing seasons. There were months of constant daylight followed by months of constant darkness. Many land animals lost their summer color and turned white to blend in with winter, though the winters weren't as white as they'd once been. Our robot was swimming through the northern ocean, under a sky filled with stars. Fear of the poison tide had driven away countless ocean animals. There were fewer fish, fewer squid, fewer seabirds. Some of the larger animals remained, for now. Roz's head dipped underwater, and she heard a flurry of clicks and whistles, and when she popped up again, she spotted a family of whales glistening in the starlight as they raced through the waves. They were narwhals. Each of the males had a long tusk extending from his head. Roz wondered where the narwhals were going. Were they moving south to a place where they wouldn't have to live in fear?

第四十五章遥远的北方遥远的北方是一个极端的地方。 整个海洋都结冰了，然后随着季节的变化而融化。 连续几个月的白昼之后是连续几个月的黑夜。 许多陆地动物失去了夏天的颜色，变成了白色，以融入冬天，尽管冬天不像以前那么白了。 我们的机器人在布满星星的天空下，游过北方的海洋。 对毒潮的恐惧驱走了无数海洋动物。 鱼、鱿鱼和海鸟都少了。 一些较大的动物暂时留下来了。 罗兹的头浸入水中，她听到一阵咔嗒声和口哨声，当她再次跳出水面时，她发现一群鲸鱼在星光下闪闪发光，它们在海浪中奔跑。 它们是独角鲸。每只雄象头上都长着一根长牙。 罗兹想知道这些独角鲸要去哪里。 他们是要搬到南方去一个不用生活在恐惧中的地方吗？

The farther Roz swam, the higher the guiding star climbed in the sky, until at last it was directly overhead. The robot stopped and treaded water. Roaming somewhere in the depths below was the Ancient Shark.

罗兹游得越远，那颗指路的星星就越高，最后它就在他的头顶上。 机器人停下来踩水。 古鲨在海底深处漫游。
