英语听力：自然百科 南极生存大作战

 In Antarctica, everyday is (an) Olympic one. These Emperor Penguins² are near the end of a two-week fishing marathon, bringing food for their hungry chicks, waiting miles away. But a challenger threatens the entire competition. A Leopard³ Seal waits at the shoreline. It's hungry too.

 

Some Emperors make the leap onto shore before it can reach them. But the Leopard Seal is patient, it knows it controls the playing field. Superb athletes, they sense the Leopard Seal, and reverse direction in a split second.

 

Seeing opening, more and more penguins stream up and out onto the ice. The momentum⁴ seems to turn the way of the penguins. Dozens  make the leap to the safety of land, until the Leopard Seal changes the rules of the game.

 

The penguins scramble⁵ to get away. Out of the water, both the seal and the penguins lose their speed and agility⁶. Only desperation remains⁷. The Leopard Seal snares⁸ a penguin¹, but the "seal victory" seems certain.

 

But the game is not over yet. Penguins will go limp rather than struggle. When the Leopard Seal loses its grip, the penguin will make a break for it. This one is gone like a shot. It rejoins its teammates safely waiting at a distance. The Leopard Seal ,though ,doesn’t give up. It still has good field position. And now, the element of surprise. The Leopard Seal won’t lose its grip this time and takes its prize into the sea. For all but one, these competitors have won the fight to see another day.
