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.

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.

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.

Charles Dickens’ novel A Tale of Two Cities is set in the years before and during the French Revolution (1789 - 1799). During its course, French revolutionaries brought down the empire and established a republic of free and equal citizens.
In reading the work, one sees that Dickens distorted some details of the French Revolution. At the beginning, Dickens notes that, in 1775, France was busy spending money. This mention of France’s spending touches briefly on what is perhaps the major cause of the French Revolution. Before the revolution, the government often borrowed money because it spent more than it raised in taxes. The increased spending and borrowing made many people’s blood boil, yet Dickens focused instead on the nobility’s oppression and exploitation of the working class, including peasants, as the causes of the revolution.
The Marquis, one of the book’s characters, ill-treats and kills many people. Thus, he represents the nobles who mistreat the lower classes. One reviewer criticized this picture as an unfair representation of French society in the mid-1700s. The reviewer pointed out that the government would have punished nobles who mistreated or murdered. Nobles may have been guilty of other evils, however, such as not feeding the starving masses after bad weather ruined crops in 1789.
Dickens’ account of the storming of the Bastille fails to mention that the gang that stormed the prison was looking for bullets and bombs to use in defense against a possible attack by the king’s troops. Dickens does include some accurate details, however, such as the crowd’s finding only seven prisoners and freeing them and the pack’s executing (处决) the prison administrator and sticking his head on a post. The scene that the women knit (编织) as they watch the executions may seem to be an odd detail, but actually many women did knit stockings for the war effort as they watched the killing machine at work.
Dickens’ descriptions of the steady stream of sentenced people into prison and the carts taking them to their deaths give readers some idea of the frequency with which officials jailed and executed people during the Rule of Terror, which lasted about a year. During the Terror, the government jailed about 250 thousand people, tried (审判) and killed about 17 thousand, and executed about 12 thousand without a trial. Those executed included people who opposed the revolution, people who offended the revolutionaries, and even some revolutionaries. About 15 percent were members of the ministry or nobility.

A.Discussed. B.Revealed.
C.Provided. D.Twisted.
2.Which of the following statements is true according to the passage?
A.A wild crowd rushed into the Bastille to fight with the royal soldiers.

D.Women were forced to work for the war supplies while watching people killed.

B.There was an extreme disorder and horror during the revolution.
C.Nobles of those days in France were loaded with heavy social responsibilities.
D.Classic literary works may serve as history textbooks to a great degree.

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). Visitors can now pay 50p for three goes on the toilet roll grabber, or a go for Carex, which Braddick described as the “Rolls- Royce of hand sanitizers.”

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.

Many famous painters worked in Antwerp during the city’s period of greatest power but Peter Paul Rubens is undoubtedly the most famous one of them. Known as Rubens House, the palace-like residence(大宅) and studio where Rubens worked and lived from 1616 until his death in 1640 is now one of Antwerp’s most visited museums.
Almost all of the works Rubens and his students created in the Rubens House have been dispersed (分散) over major museums across the whole world, but there is still an impressive collection well worth the visit.

The Rubens House even had a special viewing area which allowed visitors to see the artists at work.
Ruben bought the house at the beginning of the 17th century after his eight-year-long stay in Italy. Influenced by Italian architecture, he rebuilt the building into an Italian-styled palace with a beautiful garden and moved in the house in 1616.
After his death the building was sold. New owners modified the building greatly and by 1937, when the building was purchased by the city of Antwerp, it hardly resembled the original structure.
The impressive entrance hall, which connected the studio and the residence, is one of the few parts that survived. Other parts have been carefully restored and reconstructed after original plans and paintings of the house.
