环球慢速英语 蝙蝠(3)（在线收听）

Voice 1: Vampires are imaginary creatures. They exist in films and books. They have human-like bodies. And they usually have some kind of supernatural power. They survive by drinking blood - at night! Vampires bite their victim's neck with their sharp pointed teeth. Vampires are not real. They do not exist. But the vampire bat still takes its English name from them. This is because the vampire bat survives by drinking blood!

声音1：吸血鬼是人们幻想出来的生物。它们只存在在电影和书籍中。它们的身体和人类的身体很像。一般来说，吸血鬼都拥有某种超能力。它们通过在晚上吸血来生存下去！吸血鬼会用它们的尖牙去咬受害者的脖子。吸血鬼并不是真实存在的。它们并不存在。但是吸血蝙蝠的英文名字却因此而来。因为吸血蝙蝠通过吸血而生存。

Voice 2: The vampire bat is the only kind of bat that drinks blood. It makes a small bite in the skin of a sleeping animal. The bat has a way of helping the blood to flow. Without this, the blood would grow thick quickly, and the bat could not drink.

声音2：吸血蝙蝠是唯一一种吸血的蝙蝠。它们会在睡着的动物身上咬一小口。这种蝙蝠有种方法可以让血流动起来。如果不这样，那血液很快会变稠，这样蝙蝠就不能喝到血了。

Voice 1: The secret is in the liquid inside a bat's mouth, the saliva. The saliva contains a chemical that stops the victim's blood from becoming thick. This chemical is very interesting to scientists. In fact, they are now researching the use of this chemical. They are performing tests using the chemical to treat strokes.

声音1：秘密就在蝙蝠嘴里的液体中，也就是它们的唾液。吸血蝙蝠的唾液里含有一种化学物质，可以阻止其吸血目标的血液变稠。科学家对这种化学物质很感兴趣。实际上，他们现在正在研究如何使用这种化学物质。他们正在对利用这种化学物质治疗中风进行测试。
