英语听力：自然百科 冰冻星球 前往地球尽头—14

 Every summer over 40 million penguins¹ take to the southern ocean to feed. They're joined by thousands of whales，minks are the most numerous. They  all come here to harvest the richest ocean on earth. Carrying on south, we have our first glimpse of the frozen continent.

 

Southern humpbacks are travelling 4,000 miles from the equator and finally arriving in Antarctic.

 

Humans have long felt the lure² of this mysterious world. Yet it was only a hundred years ago that the first explorers walked inland and were confronted by the highest, driest and coldest territory on earth.

 

Every year the continent is transformed as the sea ice that surrounds it begins to disappear. This melt halves the size of Antarctic. It's the most spectacular seasonal change occurring anywhere on our planet
