The sudden outbreak of the novel coronavirus（新冠状病毒）left an uncommon threat. We don’t know how bad it will be, nor do we know for how long it will spread. But we do know that it has already infected more than 11,998,020 people and killed many around the world. It has also caused serious economic damage. We need to adapt our responses to different countries and different parts of the same country in order to limit damage. Using data well is essential to such a successful response.
Data is key to all successful public health programs. In Arrian, we raised tobacco taxes and made all indoor public places smoke-free. Smoking rates declined at first but then the decline stopped. Because we had a tracking system in place, we realized that progress had stopped. So, we produced strong and direct no tobacco ads to the public. Our program quickly reduced adult and teenager smoking, preventing more than 100,000 deaths.
Every country facing the coronavirus disease needs to strengthen their data systems to track diseases, investigate skillfully and respond fast and successfully. Fast action will save lives and save money. But building the capacity to do this isn’t free. It will cost about $1 to $2 per person per year for at least 10 years-at least $30 billion. That’s a lot of money for public health, but it’s a tiny part of the amount lost when we don’t know what we need to know about health threats.
Getting the data right is hardly quick and never easy, but it is always very important if we want to respond successfully, limit spread, and protect our communities and economy.
1.Which of the following can best describe the measure taken in Arrian?
A.proud B.unpopular C.modest D.effective
2.Why does the author talk about smoking in Paragraph 2?
A.To warn us that smoking is harmful.
B.To suggest us how to reduce smoking.
C.To show the significant role of data.
D.To protect people’s physical health.
3.What is the author’s opinion on the building of the capacity of fast response?
A.It is too expensive and many countries cannot afford it.
B.It is worthwhile and necessary to develop such a capacity.
C.It supports communities and save lives and money.
D.It requires a tiny part of the amount lost by threats.
4.What could be the best title for the text?
A.The secret of widespread threat
B.The secret of successful response
C.The secret of uncommon disease
D.The secret of right data

Nurses play a vital role on the front lines of the novel coronavirus(冠状病毒）pandemic. But a shortage of these essential health care workers could pose challenges in countries dealing with a growing number of COVID-19 cases.
"One of the lessons I hope the world learns from COVID-19 is that we must invest in nurses ," said World Health Organization Director-General Tedros Adhanom Ghebreyesus during a speech Tuesday in celebration of World Health Day.
WHO's new "State of the World's Nursing 2020" report has identified a global shortage of 5.9 million nurses. Many of those gaps are found in Africa, Southeast Asia, the Eastern Mediterranean, and parts of Latin America.
Among regions of the world, the Americas have the highest density of nurses at 83.4 per 10,000 people, followed by Europe with 79.3 nurses per 10,000 people. In contrast, there are 8.7 nurses per 10,000 people in Africa, 15.6 nurses per 10,000 people in the Eastern Mediterranean region, 16.5 nurses per 10,000 people in Southeast Asia, and 36 nurses per 10,000 people in the Western Pacific.
But there are also differences within regions. In the Americas, for example, countries such as Brazil, Canada, Chile, and the US have a higher density of nurses at close to or over 100 per 10,000 people, distorting the regional average. Many of the neighboring countries in the region have less than 50 nurses per 10,000 people. In Haiti, there are only 3.8 nurses per 10,000 people.
When based on country income, data in the report shows an unsurprising trend: The higher the income, the higher the nursing density. In low-income countries, the average density of nurses is 9.1 per 10,000 people, while the figure for high-income countries is 107.7 per 10,000 people.
But training more nurses won't solve the problem, said Dr. Giorgio Cometto, WHO coordinator on human resources for health policies and standards.
"If the country lacks the economic capacity to employ them or to create economic opportunities for them to work as nurses ... training more nurses can just go into the direction of making labor market imbalances, resulting in unemployment among nurses. And that's a huge wastage of human capital as well as financial resources," Cometto said.
The key is balancing training with the creation of employment opportunities in rural areas where there are known health worker shortages.
That may be easier said than done, especially among countries that are suffering from chronic or complex emergencies, in active conflict, or struggling in the wake of conflict. But in these settings, the international aid community can arrange its assistance with national priorities and covering recurrent costs, such as salaries, within a specified period of time, Cometto said.
1.How many nurses are needed according to WHO's new" State of the World 's Nursing 2020" report?
A.6 million. B.8.7Million.
C.3.8 Million. D.5.9Million.
2.From the figures in the passage , where are nurses most needed?
A.Africa. B.Haiti.
C.Eastern Mediterranean region. D.Southeast Asia.
3.Based on the country income what does the data in the report show?
A.The higher the income ,the more nurses are.
B.The higher the income,the more doctors are.
C.The lower the income ,the more doctors are.
D.The lower the income, the more nurses are.
4.From what Cometto said, we know that___.
A.It is easy to solve the problem of shortage of nurses.
B.It is not easy to solve the problem of shortage of nurses.
C.Training more nurses is a way to solve the problem.
D.The international aid community can arrange its assistance all the time.

Due to the outbreak of the novel coronavirus pneumonia （NCP）, people all over the world are wearing masks to reduce the risk of infection. It's a very simple but incredibly effective method to protect oneself from a variety of harmful things. In fact, masks have been helping mankind for centuries. Let's take a look at some mask-related history.
1st century
In that era, many people in Roman Empire worked underground in mines to support their families. But most of them suffered from and even eventually died of respiratory （呼吸的） illnesses. To address this problem, Pliny the Elder （23-79 AD）, a Roman philosopher and naturalist, recommended the use of animal bladder （膀胱）skins to stop dust from being breathed in. Although primitive, his idea was considered the very first recorded mask invention.
16th century
Early inventions did not stop with Pliny. Many centuries later, Italian artist and inventor Leonardo da Vinci （1452-1519）, proposed using a woven cloth dipped in water over the face to protect against the poisonous chemicals.
19th century
The design of the mask look a big step forward in the 19th century. In 1848, American Lewis Hassley became the first person to patent （注册专利）a protective mask for miners, which was a milestone in face mask history. Masks at this stage were similar to gas masks. Later, in 1897, Polish-Austrian doctor Johann von Mikulicz-Radccki designed a simple mask composed of one layer of gauze （纱中1）, recommending medical workers to wear it to prevent infection. That was the first recorded use of a surgical mask.
20th century
In 1910. an epidemic broke out in Northeast China. Chinese doctor Wu Liande designed a cheap face mask called "Wu's mask". Made of two layers of surgical gauze, it could be wrapped around the back of the head and tied in a knot. This mask was praised by experts around the world, as it was simple to manufacture （制作）and had a low production cost. Modem exploration
With several outbreaks of infectious diseases and the flu. and the rise of pollution caused by industrial waste, the materials in masks have continued to evolve to better protect its wearer. For example, in 2012 when China suffered from smog, mask models such as N95 and KN90. which can filter out this fine particulate （微 粒）mailer, became highly popular. In the future. masks will continue to improve, hopefully so will the habits of humans.
1.According to the text, why were masks invented?
A.To reduce the risk of infection.
B.To protect miners from dust.
C.To indicate patients with respiratory illnesses.
D.To protect workers from harmful chemicals.
2.What was considered a milestone in face mask history?
A.Using a woven cloth instead of animal skins.
B.Getting a patent on protective masks for miners.
C.The invention of surgical masks in 1897.
D.Using more than one layer of surgical gauze.
3."Wu's mask" grew popular around the world because.
A.it could be used multiple times B.it was simple for people to wear
C.it was cheap and easy to manufacture D.it could better protect people from smog
4.What is the text mainly about?
A.The evolution of masks. B.The benefits of using masks.
C.A comparison of different masks. D.The roles masks played at different times.

During the outbreak of novel coronavirus, cities are locked down and borders are closed. Science, on the contrary, is becoming more open. And this “open science” is already making a difference.
Soon after the epidemic started in China, a research team from Fudan University in Shanghai successfully sequenced (测定序列)the DNA of the virus. But they didn’t keep the information to themselves. Instead, they placed the sequences on GenBank, an open-access data platform, so researchers around the world could download them for free and start studying the virus.
Due to this openness, pharmaceutical (制药的) companies across the globe are now able to work simultaneously (同时地)to develop a vaccine. “There may be room for multiple different vaccines for different purposes and different age groups,” Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security in the US, told Al Jazeera. “The bigger menu we have of vaccines, the more resilient (有适应力的) we’ll be against coronavirus outbreaks in the future.”
Major drug companies around the world are also sharing their study results. Remdesivir, a drug originally developed by US company Gilead Sciences to treat Ebola, is found to be promising in fighting against the novel coronavirus. Currently, two trials of the drug are already underway in China, and the results might be available as soon as April, according to The Verge.
This openness in science is going to be even more critical in the future. “With climate change, increasing globalization, and population shifts, epidemics will not go away, and might even become more frequent,” Dan Barouch, a Harvard Medical School professor, told Harvard Magazine.
He said, “No one group can do everything. It has to be a coordinated (合作的) approach. But I do think that the world has a greater sense of readiness this time to develop knowledge, drugs, and therapeutics (疗法) very rapidly.”
Every epidemic is indeed a crisis, but it can also be a learning opportunity. One redeeming (补偿的) factor of the COVID-19 outbreak is that it is helping science adapt for the better.
1.What does the article mainly talk about?
A.Coordinated efforts to fight the epidemic.
B.Something positive we’ve learned from the epidemic.
C.The significance of openness and sharing of scientific knowledge.
D.What needs to be done to prevent future epidemics.
2.What is the positive effect of the research team from Fudan University placing the genetic sequence of the virus onto GenBank?
A.They alerted the world to the danger of the virus.
B.They helped remove people’s fear of the virus.
C.They showed the world how to produce a vaccine.
D.They invited collective efforts worldwide to develop a vaccine.
3.What is the author’s purpose of mentioning remdesivir in the text?
A.To introduce a possible cure for the epidemic.
B.To compare the treatment of Ebola and the novel coronavirus.
C.To prove that many drug companies readily share their discoveries.
D.To show that the novel coronavirus will soon be contained.
4.What does the underlined word “critical” in paragraph 5 probably mean?
A.expressing disapproval.
B.extremely important.
C.serious, uncertain and possibly dangerous.
D.making fair, careful judgments.
5.Which of the following would Dan Barouch probably disagree with?
A.Epidemics will be less frequent thanks to scientific development.
B.The world is becoming better prepared to deal with epidemics.
C.No single group can fight against the epidemics independently.
D.The increase in globalization may worsen future epidemics.

The novel coronavirus(冠状病毒), which1.(originate)in the Chinese city of Wuhan and has now spread to many countries, has much in common 2. seasonal flu. They are both viral infections, share similar symptoms and crucially(关键地) can spread from human to human. In the midst of flu season in much of the northern hemisphere, 3.(tell) the difference between the two will be vital in stopping its spread.
Human corona viruses, of 4. there are four, can cause respiratory (呼吸道)infections similar to flu: while many symptoms are mild, both can lead to pneumonia(肺炎) and become lethal(致命的). However, the novel corona virus is 5.(serious) than a “typical influenza infection,(流感)”says Ian Jones, a professor of virology at the University of Reading.
“This virus appears to go6.(far) down into the lungs than would generally be the case. Therefore, it will give you7. (symptom) of pneumonia(肺炎): the lungs becoming flooded, they don't function very well and the patient gets into breathing difficulty.”
While the mortality rates and symptoms of flu and novel corona virus may end up being similar, humans' ability 8.(fight) off the viruses differs greatly.
Flu can spread from person to person from up to six feet away, 9.(large)caused by liquid emitted when the inflicted cough or sneeze. Those infected are usually contagious for around three days following the beginning of 10. illness, although this time-frame could stretch to over a week.
All this and more remains a mystery as for the new coronavirus.

Lessons learned in past outbreaks
The novel coronavirus dominates(主导）the headlines as one of the world's most pressing issues.It has killed more people than the 2003 SARS outbreak,according to the World Health Organization（WHO).1.?
One of the biggest lessons from SARS was to share the latest information about the virus with the public and other countries in the world as quickly as possible.,2.,allowing scientists around the world to start developing a vaccine(疫亩）on Jan 12,according to Xinhua.
With experiences of fighting against SARS and MERS,many countries were also better prepared to stop the spread of coronavirus.3..During the 2012 MERS outbreak,research showed that infected camels caused the outbreak.According to the WHO,strict measures were enacted(实施）， restricting the sale of camels and camel products in the Arabian Peninsula.There were also mass health tests for all those in close contact with diseased animals.4.
In the fight against the novel coronavirus,China has also taken many effective measures to control the virus.Under the leadership and command of the central government,all provinces and municipalities(自治区）across the country have launched a Level One emergency response to the novel coronavirus.5..It is because of these effective measures that the epidemic has been constrained （限制）successfully within China,with the confirmed cases less than many other countries.
A.They also quickly isolated(隔离）those who were confirmed infected for medical care
B.Chinese health officials published the details of the new virus online
C.The number of infections overall in China are now far more than that of SARA
D.Following the measures,the number of the infected has dramatically decreased
E.The outbreak has killed many people since the first death was reported in Wuhan
F.But there is no better prevention than stopping the source
G.What can we learn from the past outbreaks,including SARS and MERS

The secret of successful response
The novel coronavirus(新冠状病毒)is an uncommon threat. We don't know how bad it will be, nor do we know for how long it will spread. But we do know that it has already infected (感染) more than 18,000 people and killed many around the world. It also caused serious global economic damage. We need to adapt our responses to different countries and different parts of the same country in order to limit damage. Using data well is essential to such a successful response.
Data is key to all successful public health programs. In New York City, we raised tobacco taxes and made all indoor public places smoke free. Smoking rates declined at first but then the decline stopped. Because we had a tracking system in place, we realised that progress had stopped. So, we produced strong and direct no tobacco ads to the public. Our programs quickly reduced adult and teenager smoking, preventing more than 10,0000 deaths.
Every country facing the coronavirus disease needs to strengthen their data systems to track diseases, investigate skillfully and respond fast and successfully. Fast action will save lives and save money. But building the capacity to do this isn't free. It will cost about $1 to $2 per person per year for at least 10 years --- at least 30 billion. That's a lot of money for public health, but it's a tiny part of the amount lost when we don't know what we need to know about health threats.
Getting he data right is hardly quick and never easy, but it is always very important if we want to respond successfully, limit spread, and protect our communities and economy.

14 days. That’s the time Chinese scientists took to identify the full genetic sequence of the novel coronavirus (新冠病毒) since its outbreak. It was shared with the WHO immediately, and has now become an important foundation for global researchers in the fight against the COVID-19. But first, let us turn the clock back 17 years, when it took months to identify the SARS virus. From months to 14 days, what changed? It turns out AI played an important part.
The scientists first obtained bronchoalveolar lavage (BAL) fluid (支气管扩张灌洗液) samples from patients, isolated (分离) the DNA and RNA, then sequenced the genetic material by comparing them. AI’s advantage is its ability to recognize patterns among a flood of data.
Let me put it in a simple way. Sequencing the coronavirus genome (基因组) is similar to looking for a needle in a haystack (干草堆)---looking for genotypes (基因型) with specific characteristics from a huge gene pool. That’s where search algorithm (算法), a branch of modern AI, comes in. Think of it as an efficient search engine, which can find the needle in the haystack. This search algorithm can shorten months-long genetic sequencing to weeks or even just a few days. Combined with macro-genomic sequencing and a virus library, this AI technology can also be used in tracking virus mutation (突变).
AI doesn’t just support scientists. It can also help patients by improving the efficiency of diagnosis (诊断). China launched a Genomics Service, which can run multiple virus gene comparisons and produce a detailed report within 60 seconds. This algorithm has been put into use in China and shared to the world for free.
1.AI’s advantage is that it can ________.
A.slow down the spread of coronavirus B.separate DNA from RNA
C.identify specific genotypes rapidly D.obtain samples from patients quickly
2.The search algorithm helps shorten the time of genetic sequencing by __________.
A.finding a needle in a haystack B.serving as a search engine
C.combining with a virus library D.tracing virus mutation
3.What do we know about the Genomics Service in the last paragraph?
A.It has been widely used in the world. B.It is mainly based on blood test.
C.It is for fast diagnosis of COVID-19. D.It is used to track COVID-19 patients.
4.What’s the best title of the passage?
A.14 Days---China Made it! B.AI Assists in COVID-19 Fight
C.Search Algorithm, Best Choice D.China’s Genomics Service
