英语听力：自然百科 走进西藏 tibet—7

 It's about 5,000 meters above sea level, way above the point at which altitude sickness starts to affect humans. At this height, most people are gasping¹ for breath. But lack of oxgygen hasn't cramped² this creature's style. 

 

Chiru, or Tibetan antelope³ have arrived for the winter rut. In the energy-sapping thin air , the males must try to control groups of females by constantly rounding them up and corralling them. But the chiru have an advantage. Their red blood cell count is twice as high as ours , sufficient to supply their muscles with oxygen, even at this extreme altitude. Nevertheless,it's hard work keeping his harem in check, and the male's life is about to get even harder. Another male is gearing up to steal his females. With their rapier-like horns,the males won't risk fighting unless they really have to. But if neither backs down, conflict is inevitable⁴. Some of these fights end in death.
