科学家斯兰德从1995年起就一直研究北极熊。2011年7月,斯兰德带领一支考察队乘船前往加拿大东北部。船行驶了一段时间,有船员在大海中发现了一只北极熊带着两只幼崽正艰难地向前游着。它们全瘦得皮包骨,应该很久没吃东西了。这时母熊看到考察船就像看到了希望,它带着孩子向船游过来。不过它不敢靠得太近。斯兰德连忙让人取了些肉投给北极熊母子。三只熊风卷残云般将十几千克肉一扫而光。斯兰德 Scientist Slande has been studying polar bears since 1995.

They are all skinny skinny, should have eaten for a long time. At this moment, the mother bears looked at the study ship as if they had seen the hope, and took the child to the boat.
