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 (流行病) 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, companies producing drugs across the globe are now able to work at the same time to develop a vaccine (疫苗). “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 flexible we’ll be when fighting 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 important 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 cooperative approach. But I do think that the world has a greater sense of readiness this time to develop knowledge, drugs, and treatment 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 in Africa.
B.Some scientific knowledge 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. The positive effect of what the research team from Fudan University did is that ________.
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 paragraph 4?
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. Which of the following would Dan Barouch probably disagree with?
A.Epidemics will be less frequent thanks to climate change.
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 bring about more epidemics.

文章大意:本文是一篇新闻报道。一个澳大利亚牧场工人的大拇指被一头公牛弄断,目前他的脚趾通过手术被移接到手指的部位。

【推荐1】April 4th was just another day on a Western Australia farm for Zac Mitchell, until it suddenly wasn’t. In an unexpected accident, the cattle worker was feeding the animals in his charge when one bull cleaned him up and kicked his hand up against the rail, resulting in the thumb on his right hand being cut off. “My thumb was still hanging on the rail... when I got up off the ground,” Zac Mitchell says.

His co-workers tried their best to preserve the thumb for reattachment, placing it on ice in a cooler, but two surgeries to put Mitchell’s thumb back in place failed. That’s when doctors came up with another suggestion: Remove one of his big toes to where his thumb used to be.

Mitchell’s lead surgeon, Sean Nicklin, understood the man’s dilemma at first, calling it a “bit of a crazy idea”. After all, Zac Mitchell did not want to be injured in another part of his body. But as the thumb is incredibly important function-wise, Mitchell eventually gave in. Nicklin explains that the big toe is surprisingly fit for a thumb switch: Nerves sync up (同步) nicely, and it looks more like a thumb, though a giant one, than any other alternative they may have come up with. He added that big toes aren’t as necessary for balance and walking as people believe. As far as the foot goes, occasional “fine balance” activities like surfing might be difficult, but most people without a big toe function fine in everyday tasks like walking and even competitive sports.

The eight-hour surgery went well, and Mitchell is expected to have a year or so of recovery in front of him before he heads back into the fields.

1. What happened to Zac Mitchell on April 4th?
A.He cleaned up a bull.B.He was badly hurt.
C.He started his farm.D.He lost his thumbs.
2. What suggestion did the doctor give to Mitchell after the unsuccessful surgery?
A.Recreating a new thumb in place.
B.Replacing the thumb with his toe.
C.Transplanting his co-worker’s thumb.
D.Putting back the cut-off thumb again.
3. What is Mitchell’s first attitude to the doctor’s another suggestion?
A.Optimistic.B.Insignificant.
C.Hesitant.D.Rejective.
4. According to Nicklin, after the surgery Mitchell is able to       .
A.surf on the seaB.do daily activities
C.only stay at homeD.work on wheelchair

文章大意:这是一篇新闻报道。文章讲述了,因为化疗和放疗与各种新药和治疗相结合、对癌症预防的关注和使用疫苗,癌症治疗存活率不断提高。

【推荐2】A cancer treatment no longer means what it used to be. Just a few decades ago, the survival rate beyond five years was less than 50%. Now, nearly 70% of those who get cancer survive that long, and that rate is set to rise. Why? Because, more than ever, chemotherapy (化疗) and radiation, once the only ways of cancer treatment, are being paired with or replaced by varieties of new drugs and treatments.

For example, the first medication for what was previously considered an “undruggable” lung cancer was recently approved in the United States, Canada, Europe and the U.K. And a brand-new precise chemotherapy drug delivered directly to breast cancer cells is giving hope to patients with the HER 2-positive form of the disease.

Another discovery has been the promise of a treatment called immunotherapy, as researchers around the world have discovered ways to use the body’s own immune (免疫) system to battle cancer cells.

Also driving hope is a focus on prevention. Decades of research and public education have led to greater awareness of how lifestyle changes can reduce our risk of developing cancer. According to an article from the journal Pharmaceutical Research and published by the National Institutes of Health, 90% to 95% of cancers can be owed to environment and lifestyle, rather than to genetic (基因的) factors.

Employing vaccines (疫苗) is another effective way of prevention. Take the mRNA cancer vaccines for example. The speedy development of COVID-19 vaccines was thanks to foundations already laid by researchers who had been working for years to create mRNA vaccines to fight cancer. These vaccines use a specially programmed molecule (分子) to activate an immune response in the body’s cells. Unlike the COVID-19 vaccines designed to help protect billions of people, each cancer mRNA vaccine is tailored to treat a single patient’s cancer.

In fact, this personalized approach can be made for everyone, and for every cancer.

1. Why is the survival rate beyond five years rising now?
A.Because new drugs and treatments have come out.
B.Because chemotherapy and radiation get advanced.
C.Because new drugs have been paired with old ones.
D.Because new treatments have replaced the old ones.
2. What can we learn from the fourth paragraph?
A.All the cancers are not related to genetic factors.
B.Most cancers have no relationship with lifestyle.
C.A focus on prevention is our only hope to deal with cancer.
D.All cancers have relationship with environment and lifestyle.
3. What can we infer about cancer mRNA vaccine according to the text?
A.The COVID-19 vaccines can be used to fight some cancers.
B.One cancer mRNA vaccine can’t be used for another cancer.
C.One cancer mRNA vaccine can be used to treat patients of the same cancer.
D.The COVID-19 vaccines were created from previous cancer mRNA vaccines.
4. What is the text?
A.A diary entry.B.A news report.
C.A book review.D.A science fiction.

文章大意:本文是新闻报道。文章主要讲述麦克林的儿子烧伤了,需要治疗,最后治疗账单得到了圆满的解决。

【推荐3】Dr. Sara McLin thought she made the right choice by going to an in-network emergency room near her Florida home after her 4-year-old burned his hand on a stove last Memorial Day weekend.

Her family is insured through her husband’s employer, HCA Healthcare, a Nashville-based health system that operates more hospitals than any other system in the nation. So McLin knew that a nearby stand-alone emergency room, HCA Florida Lutz Emergency, would be in their plan’s provider network.

But McLin said a doctor there told her she couldn’t treat her son, Keeling, because he had second- and third-degree burns that needed a higher level of care. The doctor referred them to the burn center at HCA Florida Blake Hospital, about a 90-minute drive away.

McLin, who is a dentist, said the doctor told her the stand-alone ER would not charge for the visit because they did not provide treatment.

“I don’t remember exactly how she phrased it, but something along the lines of--we won’t even call this a visit, because we can’t do anything. ” McLin said.

At Blake Hospital, a doctor diagnosed Keeling with a second-degree burn, bandaged his hand, and sent them home with instructions on how to care for the wound.

“I didn’t think anything more of it. ” McLin said.

Then the bills came.

Total Bill: For the emergency room visit, Envision Physician Services billed $829 to insurance and about $72 to the family. HCA Florida Trinity Hospital billed Keeling about $129, noting it had applied an “uninsured discount”. A list showed the original charge had been nearly $1, 509 before adjustments and discounts.

She said she called her insurer, United Healthcare, and a representative told her not to pay the bill.
