专题04 溯源新冠病毒：蝙蝠如何练成“百毒不侵”（原卷版 ）.docx

1、How do bats live with so many viruses?溯源新冠病毒：蝙蝠如何练成“百毒不侵”读前导读：这个春节，蝙蝠瞬间成为了千夫所指的对象，人们憎恶海吃野味的非理性行为，也记恨这个传播病毒的可能宿主。“天然的病毒库”是它的别称。 既然蝙蝠本身携带如此多的病毒，为什么它自己却能毫发无损？这到底是怎样的一种神奇生物呢？。Part1：高级实词分类记7名词类：1.outbreak/at.brek/n. 2.indication/n.dke.n/n. 3.strain/stren/n. 4. trace/tres/ n. 5.host/host/v. n. 6.mammal/mm

They have a weakened response, but it is still there. Thus, the r

17、现：蝙蝠是如何处理一种叫做 DNA 感应的能力的。The energy demands of flight are so great that cells in the body break down and release bits of DNA that are then floating around where they shouldnt be. Mammals, including bats, have ways to identify and respond to such bits of DNA, which might indicate an invasion of a dis

18、ease-causing organism. But in bats, they found, evolution has weakened that system, which would normally cause inflammation as it fought the viruses.飞行对于能量的需求是如此巨大，以至于蝙蝠体内的细胞会破裂并释放出 DNA 片段，而这些片段会飘散到不该去的地方。包括蝙蝠在内的所有哺乳动物，都有办法识别这些 DNA 片段，并做出反应，（因为机体会认为）这些片段或许标志着，某种引发疾病的微生物在入侵。然而研究人员发现，进化过程弱化了蝙蝠体内的这一系统，

19、通常来说，这一系统会让机体在对抗病毒时，产生炎症。Bats have lost some genes involved in that response, which makes sense because the inflammation itself can be very damaging to the body. They have a weakened response, but it is still there. Thus, the researchers write, this weakened response may allow them to maintain a “ba

20、lanced state of effective response but not over response against viruses.”蝙蝠（在进化的过程中）失去了一些与上述生理反应有关的基因，这也说得通，因为炎症本身也可能会对身体造成伤害。不过，它们的反应虽然较弱，却也依然存在。因此，研究人员写道，这一弱化的反应或许可以让它们保持“一个平衡的状态有效而非过度应对病毒”。Scientists in China were already studying the bats carefully, well aware that an outbreak like the current

21、one would most likely happen.中国的科学家们之前已经在仔细研究蝙蝠了，他们当时就很清楚，像目前这样的（病毒）爆发很有可能会发生。Dr. Peter Daszak, president of Eco Health Alliance, who has been working in China for 15years studying diseases that jump from animals to people, stressed that stopping the sale of wildlife in markets is essential to curta
