英语听力：美洲大平原-18

The scene is set for a daily ice age drama. Only the very largest are safe now.

Patience is the key, the lionesses close in, waiting for their opportunity.

The first charge causes chaos, but this is just what the lions want. ln the melee, they've already pinpointed their prey.

The leader pounces, and a horse is down. Meanwhile, the spooked herds stampede up the valley.

But they're running straight into another trap, a hidden cave, already full of ice age victims. And now it claims another. Above ground, the members of the valley pride - mothers, sisters and cubs feast.
