（单词翻译）

 For those who can get here in summer, these waters provide a feast of epic1 proportions. But the good times will be very short, a problem that faces all life in the Polar Regions.

 
Journeying the south across the Arctic Ocean, the first land you/ reach is Greenland, the largest island in the world. Despite its name, Greenland is mostly white, covered by a giant ice sheet, six times the size of the United Kingdom.
 
In the middle of the island, the ice is nearly two miles thick. It's a bleak2, quiet world. Sapphire-blue melt lakes are the first sign that a dynamic process is underway. Each lake forms in a matter of days, expanding until it's miles across and starts to overflow3
 
The spill water then carves its way/ through the ice. The water crosses through an icy delta4 like blood along the arteries5 of a cold bloody6 monster, a monster that is stirring.
 
And without warning, the water suddenly plunges7 down an open shaft8, falling a vertical9 mile into the heart of the ice sheet.
 
This melt water has a surprising effect. It lubricates the junction10 between the ice and the rock floor beneath, so the entire ice sheet is now on the move, sliding downhill into the ocean.
