环球慢速英语 蝙蝠(2)（在线收听）

Voice 2: The bat's body is designed well! A bat is not a bird. It is the earth's only flying mammal! A bat's wing has two layers of skin. The skin stretches between the bat's long finger bones, then down the side of its body and back leg. The bat's 'thumb' sticks out at the front of the wing. It is free to hold on to trees and walls.

声音2：蝙蝠的身体设计得非常好！蝙蝠并不是鸟类。蝙蝠是世界上唯一能飞的哺乳动物！蝙蝠的翅膀由两层皮肤组成。皮肤中间是蝙蝠长长的指骨，且延伸至身体的下半部分及后腿。蝙蝠的“大拇指”从翅膀上伸出来。使它们可以在树上和墙上自由攀爬。

And its wings can be about two metres across! Mega bats live in hot rainforests — such as in Africa or Australia. They eat fruit. Or, they drink the sweet liquid nectar from flowers.
