阿穆尔河

第六天早晨，火车行驶到了俄罗斯远东地区。森林的景象变了，现在有了朝鲜松、东北梣和蒙古栎。森林显得更加密集。这是世界上除热带地区外最潮湿的森林之一。

On the sixth morning, the train was in the Russian Far East. The forest had changed. There were now Korean pine, Manchurian ash, and Mongolian oak. The forest felt closer. This is one of the wettest forests in the world outside the tropics.

波莉独自待在车厢里。帕维尔已经离开了，那个士兵也走了。

Polly was alone in the compartment. Pavel had left. The soldier had moved.

一列货运列车从反方向驶过。它有两公里长，载着木材。波莉数了数，有三十八节平板车。

A freight train passed in the other direction. It was two kilometres long. It carried timber. Polly counted thirty-eight flatbeds.

火车到达了哈巴罗夫斯克。这个城市位于阿穆尔河畔。阿穆尔河是世界上第八长的河流，也是俄罗斯和中国的界河。透过薄雾，波莉可以看到对岸的中国。

The train arrived at Khabarovsk. The city is on the Amur River. The Amur is the eighth-longest river in the world. It is the border between Russia and China. Polly could see China across the river through the haze.

她下了火车，活动活动腿脚。

She got off the train to stretch her legs.

一只鹤站在沼泽边缘。它是黑白相间的，眼睛周围有红色，身高接近两米。这是俄罗斯远东的丹顶鹤，是世界上最稀有的鹤之一。现在只剩下大约三千只。

A crane was standing at the edge of a marsh. It was black and white with red around the eye. It was nearly two metres tall. This is the Russian Far East crane. It is one of the rarest cranes in the world. Only about three thousand are left.

波莉歪着头看着它，那只鹤也歪着头回望着她。他们互相注视着。

Polly tilted her head. The crane tilted its head back. They watched each other.

列车员吹响了哨子，波莉跳回了火车。她转身看去，那只鹤慢慢抬起脖子，走进了沼泽。

A conductor blew a whistle. Polly hopped back to the train. She turned and looked. The crane lifted its neck slowly. It walked away into the marsh.

火车向南行驶。太平洋现在不到七百公里远了。

The train turned south. The Pacific was now less than 700 kilometres away.
