英语听力：自然百科 大迁徙之繁衍生息 Need to Breed—13

 And the raptor executes his cool mercy.In the rolling surf, rockhoppers pop home with their garlics full. They take turns  shuttling to the sea daily  , having tibets of quilt to feed their growing chicks. Once ashore¹, the rockhoppers trade their long graceful² sea migrations³ for a daunting⁴ and dangerous vertical⁵ one. They made their nests high on the sheer cliffs far from the freezing sea spray. And each day, podgy with baby food, they must scale these unforgiving rock moles⁶.  Centuries of penguin⁷ passage have left their mark.
