我相信自己能听到，有一头重达1 500磅的雄性北极熊正朝我走来。
I had convinced myself that I could hear a male 1, 500-pounder heading my way.
然而，保卫它们的北极熊（白熊）只意味着一件事情：布拉瓦海岸的萨尔瓦多·达利（Salvador Dalí）的家。
The polar bear that guards them, however, means only one thing: Salvador Dalí's home in Costa Brava.
熊在活跃时每分钟心率达100次；冬眠时，心率降到每分钟8次。
The heart rate of active bears is around 100 beats a minute; for hibernating bears it can drop to eight beats a minute.
