[音乐播放]旁白
[MUSIC PLAYING] NARRATOR:
蝙蝠翅膀的用途不仅仅是飞行
Flying foxes wings areuseful for far more than just flying.
翼膜在骨架上伸展开来
The membranes are spreadout over a skeleton
很像人类细长的手 但它们只有一根手指
resembling an elongated humanhand, equipped with a thumb
但和人的手指一样十分有用
And just like human thumbs,they’re immensely useful.
它们是便利的钩子 更是攀爬工具
They work as handyhooks and climbing gear.
它们帮助蝙蝠在树木间量出向上的路
They help the flying foxesscale their way up trees
并且能精确计算 避开难以飞进去的地方
and maneuver themselves into positions it would be hard to fly into.
