英语听力：自然百科 北极熊 冰上间谍 Spy_Bear—21（在线收听） |
Blizzardcam nearly met its match with the most playful bear it's ever encountered. The bear wanted to know how it worked. Blizzardcam deployed snowballcam as a decoy. This was the polar bears' favorite spy camera and this young male was no exception. Never before had it come under so much pressure. Valiantly, snowballcam kept filming until the very end. Fortunately, for most of the time, the spycams were ignored, capturing intimate moments like this. But icebergcam finally found itself trapped between ice floes. As ever, the mother's curiosity is piqued. The curiosity that helped the mother and cub survive is now testing icebergcam to destruction. This same curiosity is this cub's and all polar bears' best hope for the future.
