in other seasons there might be 20 of us and only a few of them.but now, in the heart of winter, there are 20 of us and 150 of them.we are homo sapiens, a gaggle of bird-watchers, scientists, and photographers; they are grus japonensis, the rare and celebrated red-crowned crane.
如果是在别的季节，我们这边的人马大概会有20个，而对方只会有几个。但是现在正值隆冬，我们这边的数目还是20，对方却增加到150。我们是人类，一群嘈杂的赏鸟人士、科学家和摄影师;它们则是grus japonensis，也就是罕见而知名的丹顶鹤。
