（单词翻译）

 Their secret is teamwork. Impala are their favourite prey1. They start to hunt and the pack splits up. An aerial viewpoint gives a new insight into their strategy. As the dogs approach their prey, they peel off to take up separate positions around their target. They seem to form a cordon2 around the impala. Moving in total silence, they take up their positions. Those ears can detect the slightest rustle3. 

 
The hunt is on. Three dogs close in on one impala. Missed. The lead dog drives the impala towards the hidden flankers. Anticipating their line, the leader cuts the corner and joins a flanker for the final assault. It’s all or nothing—one on one. The dog has stamina4. The impala has speed. Leaping into the lake is an act of desperation—impala 
 
can barely swim.
