阅读下面的文字，完成下面4-6小题:材料一:近期新冠肺炎肆虐，蝙蝠又一次成了人们的话题中心。

大家好奇，许多烈性传染病的大流行都与蝙蝠脱不了干系，但蝙蝠自己却不发病。

今天，神秘的蝙蝠将为我们一一解疑。

问：外界将你们称作病毒库的说法准确吗?答:可以这么说。

我们有1000 种不同类型的亲戚，是地球上第二丰富的哺乳动物，目前你们从我们身上分离出的病毒有100多种，其中有些被证实可以直接感染牲畜甚至人类。

比如在你们人类中大规模流行的埃博拉病毒、马尔堡病病毒、SARS病毒等，当初和我们在一起时并没有显得多恐怖，可能是它们怕我们吧。

问：有什么秘密或器来降伏它们，让其不敢放肆?答:和你们相比，我们主要有高体温和特殊的免疫系统。

作为目前唯一可持续飞行的哺乳动物，我们的体温和鸟类相似，基本上在38-41°C，相当于人类的高烧状态。

同时，高体温也使我们的机体免疫代谢速率一直处于较高水平，能够在需要时快速有效地响应病毒入侵，这都让它们不敢在我们体内造次。

问：但是你们却基本上不发病。

答:是的。

当然也有其它因素，比如我们作为群居动物，亲成们聚在同一个空间里生活，为我们增加了交叉感染的机会，这会促进病毒变异。

当然，我们在冬眠过程中也会降低代谢速率抑制病毒繁殖。

世代演变下来，我们蝙蝠与病毒算是共生关系，各取所需。

互不伤害。

(摘自胡慧祯《蝙蝠采访记》）材料二:冠状病毒为不分节段的单股正链RNA病毒，属于巢病毒目、冠状病毒科、正冠状病毒亚科。

冠状病毒是一类主要引起呼吸道、肠道疾病的病原体，1937年首次从家禽体内分离，最早在人体内发现是在1965年。

在电子显微镜下，这类病毒颗粒的表面有许多规则排列的突起，整个病毒颗粒就像一顶中世纪欧洲帝王的皇冠，因此被命名为“冠状病毒”。

在自然界中，冠状病毒广泛存在于动物体内，必须依赖宿主细胞才能繁衍。

冠状病毒的宿主丰富多样，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。

COVID-19 could cut wildlife trade新冠肺炎肆虐让野生动物背锅Conservation experts are saying that the trade in wildlife could be greatly cut after the coronavirus pandemic has finished. They say that the virus probably started at a market selling wild animals in China. The virus came from either a bat or an animal called a pangolin. It then crossed over to infect humans. The conservation group Humane Society International said: "The consumption of wild animals which can carry diseases that can cross the species barrier poses a real threat to human health." The Wildlife Conservation Society called for a ban of animal markets that trade in wildlife. It said: "Not only will this help to prevent the spread of disease, it will address one of the major drivers of species extinction."A spokesman from the Zoological Society of London said animal markets could be "time bombs". He said the markets can provide perfect conditions for new viruses to start and grow. He added that if we treated animals like goods to buy and sell, we would be in trouble again in the future. Scientists say many new outbreaks of viruses start in animals. About 75 percent of new infectious diseases come from animals. Recent examples include SARS, MERS and Ebola. Infections from animals cause millions of illnesses and deaths worldwide every year. An expertsaid the world must act soon, because, "realistically, it's just a matter of time before the next zoonotic disease risk emerges".材料来源：https:///news/science-environmen生词表conservation （自然环境、文物）保护pandemic 大流行病pangolin 穿山甲consumption 消费species barrier 物种屏障poses a real threat 构成真正的威胁address 解决处理extinction 熄灭Zoological 动物的，动物学的infectious 传染的realistically 现实地zoonotic [医] 动物传染病的emerge 出现，浮现参考译文COVID-19可能会切断野生动物贸易保护专家说，在冠状病毒大流行结束后，野生动物贸易可能会大大减少。

短文改错：How does the disease present?Well, from what is known so far, there can be（改为a）the number of symptoms range(改为ranging) from mild to severe. There can be fever and respiratory symptoms such as cough and short(改为shortness) of breath. In more severe case(改为cases), there’s been pneumonia(肺炎), kidney failure(肾衰竭), and death. The mortality rate(死亡率) was(改为is) not known yet.How can we tell if(改为whether) someone is infected or not?The infection can be diagnosed(诊断) by a test calling(改为called) PCR or Polymerase Chain Reaction(聚合酶链反应). This test identifies the virus basing(改为based) on its genetic fingerprint(指纹). There is current(改为currently)no specific medication for the virus and treatment is supportive care. There’s no currently vaccine(疫苗) to protect(+against)the virus. Treatment and vaccines are in development.阅读理解：ReadingIn December 2019, there was a cluster of pneumonia(肺炎) cases in China. Investigations found that it was caused by a previously unknown virus-now named the 2019 Novel Coronavirus. In this text,we’ll take a quick look at what’s currently known about the virus. Keep in mind(记住) that this is a new virus and what’s known about the virus now might change in the future.Coronaviruses(冠状病毒) are a large group of viruses. They consist of a core of genetic material（遗传物质）surrounded by an envelope with protein spikes(蛋白棘突). This gives it the appearance of a crown. Crown in Latin is called “corona”and that’s how these viruses get their name.There are different types of coronaviruses that cause respiratory(呼吸的) and sometimes gastrointestinal(胃肠的) symptoms. Respiratory disease can range from the common cold to pneumonia(肺炎). And in most people, the symptoms tend to be mild. However, there are some types of coronaviruses that can cause severe disease. These include the Severe Acute Respiratory Syndrome (SARS即严重急性呼吸综合征，俗称“非典”) coronavirus first identified in China in 2003 and the Middle East Respiratory Syndrome (MERS中东呼吸综合征) coronavirus that was first identified in Saudi Arabia(沙特阿拉伯) in 2012.The 2019 Novel Coronavirus was first identified in China. It initially occurred in a group of people with pneumonia(肺炎) who’d been associated with a seafood and live animal market in the city of Wuhan. The disease has since spread from those who were sick toothers, including family members and health care staff(员工；全体职员). There are many cases at present and the disease has spread within China and also to a number of other countries.So, where did the virus come from?It’s known that coronaviruses(冠状病毒) circulate in a range of animals. Sometimes these viruses can make the jump from animals to humans. This is called a spillover and could be due to a range of factors such as mutations(变异) in the virus or increased contact between humans and animals. For example, MERS-CoV is known to be transmitted from camels and SARS-CoV, from civet cats(果子狸). The animal reservoir of the 2019 Novel Coronavirus is not known yet.Questions：1.Why was the novel virus named “coronavirus”?Because coronaviruses(冠状病毒) are a large group of viruses. They consist of a core of genetic material（遗传物质）surrounded by an envelope with protein spikes(蛋白棘突). This gives it the appearance of a crown. Crown in Latin is called “corona”and that’s how these viruses get their name.2.Was 2019-nCoV transmitted from bats(蝙蝠)?No.The animal reservoir of the 2019 Novel Coronavirus is not known yet.3.How many types of coronaviruses are introduced in the passage? There are three different types of coronaviruses introduced in the passage.These include the Severe Acute Respiratory Syndrome (SARS) coronavirus first identified in China in 2003, the Middle East Respiratory Syndrome (MERS中东呼吸综合征) coronavirus that was first identified in Saudi Arabia(沙特阿拉伯) in 2012, and the 2019 Novel Coronavirus.语篇填空：How do we prevent transmission of the virus?This new virus currently has a 1 (limit) geographic spread. 2 , there are a number of standard hygiene(卫生) practices 3 have been recommended to protect against infection and further spread. These include covering your mouth and nose when coughing or sneezing with a medical mask, tissue or flexed elbow; avoiding close contact with those who are unwell; the appropriate useof 4 (mask) and personal protective equipment, 5 (especial) in a healthcare setting; washing hands regularly with soap and water, or alcohol-based hand rub. Actions that can be taken to prevent infection from______6____animal source include: avoiding unnecessary unprotected contact with animals; washing hands after contact with animals or animal products; and ensuring that animal products are cooked thoroughly before they 7 (consume).8 is important to stay home if you’re feeling unwell. But if you have a fever, cough, and difficulty 9 (breath) , seek medical care early and share your previous travel history 10 your healthcare provider.答案：1.limited2.However3. that/which4.masks5. especially6.an7. are consumes8. it9. breathing 10. with写作：倡议书——从小事做起共战疫情假定你是学生会主席李华，当前新冠状病毒肆虐，请你围绕“从小事做起共战疫情”这一主题，给全校学生写一封英文倡议书。

Dancing to heal the body“空中课堂”舞动“云上芭蕾”。

On a recent Thursday morning, at home and facing a tiny camera, Orlando Ballet dancer Adam Boreland practices in quarantine (隔离), while his students watch his moves.Boreland’s online ballet class is one aspect of the partnership between the Orange County school district and major Central Florida arts organizations. It is a partnership that has taken new directions ever since the coronavirus shut down local schools.Other “distance learning” arts instruction comes from Orlando Repertory Theatre, Opera Orlando, Orlando Museum of Art and the Orlando Philharmonic Orchestra.The Repertory Theatre designs workshops for theater students, such as how to design sets at home, and then reviews the results. The Philharmonic’s musicians are providing individual instrument lessons to students in low-income areas, while theopera company is leading master classes (大师讲堂) for choral students and teaching performance tips. The art museum creates educational programming for both elementary and secondary students.Across the district, roughly 5,900 students study dance in about 25 programs, according to Scott Evans, director of the school district’s fine arts curriculum. The goal is to let as many as possible attend an Orlando Ballet class.Boreland’s class includes students from Apopka, Freedom, University, Wekiva and Windermere High, as well as Timber Creek. “We’re stuck inside. You really want to emote and heal the body through dance,” Boreland tells them.He also gives online dance feedback. “Keep the foot connected to the floor,” he says. “Don’t change the hips; save it for hip-hop class.”Sophomore Alessandra Lozzi, a two-year member of the Timber Creek dance team, appreciates the chance to “soak up (吸收) information” from Boreland. “His technique, his passion for dancing ... I love it,” she said.The instruction and interaction help the ballet company with its mission of reaching out to the community, said Orlando Ballet School director Phillip Broomhead.“It’s tremendous (绝妙的) that we are able to collaborate,” he said. “It’s giving the students a glimpse of people living the dream right now.”Boreland’s class ends with students’ thank-you comments flooding the online chat window.Lozzi, who hopes to dance professionally one day, can’t wait for another session. “It’s inspiring,” she said.（选自Reader’s Digest）1.

2020年新冠病毒疫情英语作文知识点，阅读理解解析冠状病毒(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.冠状病毒是一个庞大的病毒家族，目前已知会感染人类的有六种(新发现的这种是第七种)。

科学家如何突破国界差异？一起来学习今天的文章。

COVID-19 Changed How the World Does Science, Together While political leaders have locked their borders, scientists have been shattering theirs, creating a global collaboration unlike any in history. Never before, researchers say, have so many experts in so many countries focused simultaneously on a single topic and with such urgency. Nearly all other research has ground to a halt.Normal imperatives like academic credit have been set aside. Online repositories make studies available months ahead of journals. Researchers have identified and shared hundreds of viral genome sequences. More than 200 clinical trials have been launched, bringing together hospitals and laboratories around the globe.On a recent morning, for example, scientists at the University of Pittsburgh discovered that a ferret exposed to Covid-19 particles had developed a high fever — a potential advance toward animal vaccine testing. Under ordinary circumstances, they would have started work on an academic journal article.“But you know what? There is going to be plenty of time to get papers published,” said Paul Duprex, a virologist leading the university’s vaccine research. Within two hours, he said, he had shared the findings with scientists around the world on a WHO conference call. “It is pretty cool, right? You cut the crap, for lack of a better word, and you get to be part of a global enterprise.”生词好句：1.lock UK /lɒk/ US /lɑːk/ vt. 上锁，封闭（close）n. 锁2.shatter UK /ˈʃætə/ US /ˈʃætər/ vt. 打破（to break suddenly into very small pieces, or to make sth. break in this way）；彻底毁坏，破灭（to completely destroy or ruin sth.）近义词：breakThe plate hit the floor, and shattered into tiny bits.盘子掉在了地板上，摔得粉碎。

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？2、What does DNA sensing mean?4.How to curtail future outbreaks of similar viruses?5.Why do bats not die of the deadly viruses in its body?Part5：报刊复杂句式剖析。
