2020中考:新型冠状病毒相关的英语知识点

　　英语

　　【知识点】

　　冠状病毒(coronavirus)是一类主要引起呼吸道、肠道疾病(respiratory and intestinal diseases)的病原体。这类病毒颗粒的表面有许多规则排列的突起(a fringe of bulbous surface projections )，整个病毒颗粒就像一顶帝王的皇冠(royal crown)，因此得名“冠状病毒”。冠状病毒除人类以外，还可感染猪、牛、猫、犬、貂、骆驼、蝙蝠、老鼠、刺猬等多种哺乳动物以及多种鸟类(mammals and birds)。

　　2019-nCoV， as it's been labelled， is understood to be a new strain of coronavirus that has not previously been identified in humans.

　　这种新型冠状病毒(2019-nCoV)此前未在人类身上发现过。

　　Coronaviruses are a broad family of viruses， but only six (the new one would make it seven) are known to infect people.

　　Signs of infection include respiratory symptoms， fever， cough， shortness of breath and breathing difficulties.

　　感染症状包括：呼吸道症状，发烧，咳嗽，呼吸短促，呼吸困难等。

　　近期，湖北省武汉市等多个地区发生新型冠状病毒感染的肺炎疫情。

　　【阅读理解】

　　A new Chinese coronavirus， a cousin of the SARS virus， has infected more than 1000 people since the outbreak (爆发) began in Wuhan， China， in December. Scientist Leo Poon， who first decoded the virus， thinks it likely started in an animal and spread to humans.

　　"What we know is it causes pneumonia (肺炎) and then doesn't respond to antibiotic(抗生素) treatment， which is not surprising， but then in terms of mortality (死亡率)， SARS kills 10% of the individuals，" Poon， a virologist(病毒学家) at the School of Public Health at The University of Hong Kong， said.

　　The World Health Organization offered guidance to countries on how they can prepare for it， including how to monitor for the sick and how to treat patients.

　　Here are seven things you should know about a coronavirus.

　　What is a coronavirus

　　Coronaviruses are a large group of viruses that are common among animals. In rare cases， they are what scientists call zoonotic[?z????n??t?k](人畜共患病)， meaning they can be transmitted from animals to humans， according to the US Centers for Disease Control and Prevention.

　　Coronavirus symptoms(症状)

　　The viruses can make people sick， usually with a mild(轻度) to moderate(中度) upper respiratory tract illness(上呼吸道疾病)， similar to a common cold. Coronavirus symptoms include a runny nose， cough， sore throat， possibly a headache and maybe a fever， which can last for a couple of days.

　　For those with a weakened immune system， the elderly and the very young， there's a chance the virus could cause a lower， and much more serious， respiratory tract illness like a pneumonia or bronchitis [br???ka?t?s](支气管炎).

　　There are a handful of human coronaviruses that are known to be deadly.

　　Middle East Respiratory Syndrome(中东呼吸综合征)， also known as the MERS virus， was first reported in the Middle East in 2012 and also causes respiratory problems， but those symptoms are much more severe. Three to four out of every 10 patients infected with MERS died， according to the CDC.

　　Severe Acute Respiratory Syndrome(严重急性呼吸综合征)， also known as SARS， is the other coronavirus that can cause more severe symptoms. First identified in the Guangdong province in southern China， according to the WHO， it causes respiratory problems but can also cause diarrhea [?da???ri?](腹泻)， fatigue (疲劳)， shortness of breath， respiratory distress (呼吸窘迫) and kidney failure (肾衰). Depending on the patient's age， the death rate with SARS ranged from 0-50% of the cases， with older people being the most vulnerable.

　　How it spreads

　　Viruses can spread from human contact with animals. Scientists think MERS started in camels， according to the WHO. With SARS， scientists suspected civet cats (狸猫) were to blame.

　　When it comes to human-to-human transmission of the viruses， often it happens when someone comes into contact with the infected person's secretions [s??kri??(?)n](分泌物).

　　Depending on how virulent [?v?r?l?nt] (有毒的)the virus is， a cough， sneeze or handshake could cause exposure. The virus can also be transmitted by touching something an infected person has touched and then touching your mouth， nose or eyes. Caregivers (护理人员) can sometimes be exposed by handling a patient's waste， according to the CDC.

　　文章翻译

　　一种新的中国冠状病毒，是SARS病毒的一个堂兄弟，自去年12月在中国武汉爆发以来，已经感染了1000多人。科学家LeoPoon首先破译了这种病毒，他认为它很可能是从动物身上开始传播到人类身上的。香港大学医学院公共卫生学院的病毒学专家Poon说：“我们知道这会导致肺炎(PoT)，然后对抗生素治疗无效，这并不奇怪，但就死亡率而言，SARS杀死了10%的个体。” 世界卫生组织向各国提供了如何做好准备的指导，包括如何监测病人和如何治疗病人。

　　关于冠状病毒你应该知道七件事。

　　什么是冠状病毒

　　冠状病毒是一大类常见于动物的病毒。据美国疾病控制和预防中心称，在极少数情况下，它们是科学家所称的人畜共患疾病，也就是说它们可以从动物传染给人类。

　　冠状病毒症状

　　这种病毒能使人生病，通常是轻微(或中度)上呼吸道疾病，类似于普通感冒。冠状病毒的症状包括流鼻涕、咳嗽、喉咙痛，可能是头痛，也可能是发烧，持续几天。对于那些免疫系统弱的人，老年人和非常年轻的人来说，病毒有可能引起一种较低、更严重的呼吸道疾病，如肺炎或支气管炎。

　　有一些人类冠状病毒已知是致命的。

　　中东呼吸综合征(Middle East Respiratory Syndrome，简称MERS病毒)于2012年在中东首次报道，也会引起呼吸系统问题，但这些症状要严重得多。疾控中心称，每10名感染MERS的患者中就有3至4人死亡。

　　严重急性呼吸综合征(Severe Acute Respiratory Syndrome，简称SARS)是另一种能引起更严重症状的冠状病毒。据世卫组织称，首次发现于中国南方的广东省，它会引起呼吸系统问题，但也会引起腹泻、疲劳、呼吸急促、呼吸窘迫和肾衰竭。根据病人的年龄，SARS的死亡率在0-50%之间，其中老年人最易感染。

　　如何传播

　　病毒可以从人类与动物的接触中传播。据世界卫生组织称，科学家认为，MERS是从骆驼开始的。对于非典，科学家们怀疑是麝香猫引起的。当涉及到人与人之间的病毒传播时，通常发生在有人接触到受感染者的分泌物时。

　　根据病毒的毒力，咳嗽、打喷嚏或握手都可能导致暴露。这种病毒也可以通过触摸被感染者触摸过的东西，然后触摸你的嘴、鼻子或眼睛来传播。根据疾病预防控制中心(CDC)的说法，医务人员有时可以通过处理病人的废物来暴露自己。
