时间：2018-12-30 作者：英语课 分类：国家地理2008年
In Antarctica, everyday is (an) Olympic one. These Emperor Penguins 2 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 Leopard 3 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 momentum 4 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 scramble 5 to get away. Out of the water, both the seal and the penguins lose their speed and agility 6. Only desperation remains 7. The Leopard Seal snares 8 a penguin 1, 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.
