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.

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 coronavirus outbreak has sparked panic buying of toilet paper and cleaning products in countries across the world, but one UK businessman is determined to spread some happiness among the anxiety and confusion.
Rob Braddick, 48, who owns Braddick’s Holiday Park in Westward Ho, Devon, in the southwest of England, has filled the toy grabber machines in his amusement park with two of the country’s most sought-after cleaning products.
Customers could previously try their hand at grabbing “Frozen 2” or “Peter Rabbit” toys from the machines, but no more. “They got removed this morning,” Braddick said of the toys, replacing them with toilet roll and hand sanitizer (洗手液).

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.

On January 27th, in order to win the new pneumonia Resistance War (抗击新型肺炎战), the Ministry of Education issued a notice on putting off the start time of school in spring 2020. It was said that school should not start before February 17th. The exact start time of school will depend on situations and further notices.
However, many parents are very worried that putting off the start of school may affect children’s studies. It they have such a long winter vacation, children will not learn any knowledge, read books or study at all. They may forget what they have learnt before. Staying at home for a long time will make them keep eating, sleeping and playing, which seriously affect their physical and mental health.
In short, the close of school influences learning and develops bad habits, so how should we avoid these problems? Local education departments have also issued a notice, that is, to organize online teaching and create a network platform, where necessary courses will be shown every day, and online teaching will be given by excellent teachers of the subject, and students can learn at home through computer or mobile network.
It should be said that such a method is very good. It can not only keep students indoors and not worry about the infection of the disease, but also make them study at home, improve their learning ability, and truly achieve “no suspension of classes”. Both the platform itself and the recorded lesson resources are more useful, and are welcomed by parents and teachers.
Of course, except for learning at home, it is also necessary to teach children about health knowledge, especially how to keep away from touching virus; at the same time, it is also necessary for children to do some physical exercises or some games, which is good for physical health at home.
1.Parents worried about putting off the start time of school because ____.
A.children may be infected by virus
B.they don’t like the idea of online learning
C.children’s study may be affected
D.parents have no time to look after children
2.Except for learning at home, what is also necessary according to the writer?
A.To keep playing online games.
B.To keep touching different people.
C.To do some physical exercise outside.
D.To teach children about health knowledge.
3.The underlined word “suspension” in Paragraph 4 probably means ___.
A.plan B.stop
C.growth D.change
4.What’s the best title for this passage?
A.A Special Way to Learn at Home B.A New War with a New Change
C.A Way to Keep Mentally Healthy D.A Method to Make Parents Unworried
