Mammals, including bats, have ways to identify and respond to such bits of DNA, which might indicate an invasion of a disease-causing organism. But in bats, they found, evolution has weakened that system, which would normally cause inflammation as it fought the viruses.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 “balanced state of ‘effective response’ but not ‘over response’ against viruses.”Scientists in China were already studying the bats carefully, well aware that an outbreak like the current one would most likely happen.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 curtail future outbreaks. But monitoring and studying wildlife, like bats, is equally important.1、What does the word “inflammation”mean？[ UC ] a condition in which a part of the body becomes red, sore and swollen because of infection or injury 发炎；炎症2、What does DNA sensing mean?cells in bats’ body break down and release bits of DNA that are then floating around where they shouldn’t be. Mammals, including bats, have ways to identify and respond to such bits of DNA, which might indicate an invasion of a disease-causing organism.3. How to curtail future outbreaks of similar viruses?stopping the sale of wildlife in markets is essential to curtail future outbreaks. But monitoring and studying wildlife, like bats, is equally important.4.Why do bats not die of the deadly viruses in its body?this weakened response may allow them to maintain a “balanced state of ‘effective response’ but not ‘over response’ against viruses.”Part5：报刊复杂句式剖析。

1.Mammals, including bats, have ways to identify and respond to such bits of DNA, which might indicate an invasion of a disease-causing organism.翻译：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。

解析：本句是一个主从复合句。

主句为：Mammals have ways to identify and respond to such bits of DNA. 其中定语从句：which might indicate an invasion of a disease-causing organism.修饰先行词：such bits of DNA.2. But in bats, they found, evolution has weakened that system, which would normally cause inflammation as it fought the viruses.翻译：然而研究人员发现，进化过程弱化了蝙蝠体内的这一系统，通常来说，这一系统会让机体在对抗病毒时，产生炎症。
