BBC环球慢速英语 第137期:Bats 蝙蝠(2)

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。

voice 1: There are almost a thousand different kinds of bat! But all bats fit into one of two main groups — 'mega bats' or 'micro bats.' Mega bats are large. A mega bat can weigh up to one kilogram. 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.
声音1：世界上有近一千种不同的蝙蝠！但是，所有的蝙蝠都可分为两大类：“巨型蝙蝠”和“微型蝙蝠”。巨型蝙蝠身形很大。巨型蝙蝠的重量可达1公斤。它们的翅膀可以达到两米长！巨型蝙蝠生活在炎热的热带雨林地区，比如非洲和澳大利亚。它们吃水果。它们也喝花朵分泌的液体花蜜。

voice 2: Micro bats are much smaller. The smallest weighs only about two grams. And its wings are about fifteen centimetres across. Micro bats live all over the world. They eat mostly insects. One of the most well known bats is a micro bat. It is the vampire bat! People take an interest in this bat mainly because of its name — vampire bat!
声音2：微型蝙蝠身形要小很多。最小的微型蝙蝠可能只有两克重。它们的翅膀只有15厘米长。微型蝙蝠遍布全世界。它们主要以昆虫为食。其中一种最为知名的蝙蝠就是微型蝙蝠。这种蝙蝠就是吸血蝙蝠！人们对这种蝙蝠感兴趣主要是因为它们的名字——吸血蝙蝠！
