1 . What is a hero? We may think of the fictional characters with supernatural powers or great people who can influence world events. Now, as the nation continues its all-out efforts to fight against the novel coronavirus pneumonia(COVID-19), medical staff have become heroes in the eyes of the public.

As of Feb 19, a total of 32,000 medical staff outside Hubei province have been working to treat patients around the center of the outbreak.

Zhang Dingyu, the president of Wuhan Jinyintan Hospital, is one of these heroes. Since the hospital received the first seven patients in December, Zhang has been so busy that he barely gets any sleep. Even suffering from amyotrophic lateral sclerosis (肌萎缩侧索硬化), the 56-year-old doctor is doing his best to quicken his pace to save precious time for infected patients. “I have to run, racing against time to save more patients from the deadly disease, because I don’t have much time left in my life,” Zhang told Xinhua News Agency.

With the duty of saving lives, many medical professionals like Zhang have been working long hours for days, despite their fear and worries.

Lu Jingjing from Wuhan Children’s Hospital also works at a temporary mobile hospital. She does not let her parents know that she is now working with novel coronavirus-infected patients.

When her parents ask for a video chat, Lu says she is working and lets her husband and children chat with them instead.

“It’s dangerous but we should win the battle with the virus as soon as possible, so that medical staff and patients can go back home,” she told China Daily.

US writer Khalil Gibran (1883-1931) once wrote, “Tenderness and kindness are not signs of weakness and despair, but the manifestations of strength and resolution.” It’s true for the medical workers.

Everyone has fear, especially when it comes to deadly diseases. But for medical staff, saving lives comes first and is enough for them to be brave and stay on the front. They may look like ordinary people in daily life, but in these extraordinary times, they are heroes.

2 . Joseph Goldberger was a doctor for the United States Public Health Service and he was an advocate for scientific and social recognition of the links between poverty and disease. In 1914, Goldberger was asked by US Surgeon General Rupert Blue to study a skin disease that was killing thousands of people in the South. The disease was pellagra (糙皮病)．

Goldberger traveled to the state of Mississippi where many people suffered from pellagra. He studied the victims and their families. Most of the people lived a hard life. The doctor came to believe that the disease didn’t pass on from one to another, but was instead related to food. He received permission from the state governor to test this idea at a prison. Prisoners were offered pardons if they took part. One group of prisoners received their usual foods, mostly corn products. A second group ate meat, fresh vegetables and drank milk. Members of the first group developed pellagra. The second group did not.

But some medical researchers refused to accept Goldberger’s idea. For the South, pellagra was more than simply a medical problem. There were other things, including Southern pride.

So Goldberger had himself injected (注射) with blood from a person with pellagra. He also took liquid from the nose and throat of a pellagra patient and put them into his own nose and throat. He even swallowed pills that contained skin from pellagra patients. An assistant also took part in the experiments. So did Goldberger’s wife. None of them got sick.

Joseph Goldberger died of cancer in 1929. He was fifty­five years old. Several years later, researchers discovered the exact cause of pellagra: a lack of vitamin B₃ known as niacin.

B．Pellagra could be cured.

C．Pellagra didn’t spread.

D．Pellagra wasn’t a medical problem.

3. Why did some medical researchers refuse to accept Goldberger’s idea?

A．Goldberger’s idea sounds ridiculous.

B．They have done their own research.

C．The result hurt their pride.

D．Goldberger didn’t do enough research.

4. Which words can be used to describe Goldberger?

A．Selfless and friendly.	B．Devoted and determined.

3 . Even though vaccination (接种疫苗) is a powerful defense against disease, some voices are against it. In a recent letter, the American Medical Association (AMA) urged big social media including Amazon, Facebook and Google to take action to defend medical science on their platforms.

It said that vaccine -preventable diseases that do harm to the public health like measles (麻疹) are on the rise. Measles cases worldwide jumped more than 30% in 2017 compared to 2016, with the largest increases seen among nations in the Americas, Europe and the Eastern Mediterranean. Vaccine-preventable diseases are increasing largely because many people are unwilling to get vaccinated. And some of these people even encourage others to refuse vaccination. So this year, the World Health Organization (WHO) declared the anti-vaccination movement a top 10-health threat.

“Vaccination is one of the most cost-effective ways of avoiding disease—it currently prevents 2-3 million deaths a year, and a further 1.5 million could be avoided if global coverage of vaccinations improved,” WHO said.

A research article published in 1998 in a medical journal suggested a link between a vaccine and the development of autism (孤独症) in young children. Although the research has been suspected and many other studies have proved that vaccinations do not cause autism, the article is still impressing people strongly today. Another reason for the growth in the anti-vaccination movement is widespread misinformation on social media, which can turn people against vaccination.” If a concerned parent consistently sees information in their Newsfeed that casts doubt on the safety of vaccines, it could cause them to disregard the advice of their children’s physicians and public health experts and refuse to follow the recommended vaccination schedule. So access to true information about vaccine safety is badly needed.

1. What does the AMA require social media to do on their platforms?

A．Stop vaccine misinformation.

B．Unite to develop new vaccines.

C．Give up the anti- vaccination movement.

D．Introduce Vaccine-preventable diseases.

2. Why does the author mention the measles cases?

B．To show the result of anti-vaccination.

C．To prove some countries refuse vaccination.

D．To explain the reason for avoiding vaccination.

3. Which of the following play an important role in the anti- vaccination movement?

A．The costs of vaccination.	B．The social media platforms.
C．The concerns of vaccine safety.	D．The articles about autism.

4. Where is this text most likely from?

A．A novel.	B．A brochure.
C．A diary.	D．A magazine.

4 . Close your eyes for a minute and imagine what life would be like if you had a hundred dollars less. Also imagine what it would be like spending the rest of your life with your eyes closed. Imagine having to read this page, not with your eyes but with your finger-tips.

With existing medical knowledge and skills, two-thirds of the world's 42 million, blind should not have to suffer. Unfortunately, rich countries possess most of this knowledge, while developing countries do not.

ORBIS is an international non-profit organization which operates the world's only flying teaching eye hospital. ORBIS intends to help fight blindness worldwide. Inside a DC-8 aircraft, there is a fully-equipped teaching hospital with television studio and classroom. Doctors are taught the latest techniques of bringing sight back to people there. Project ORBIS also aims at promoting peaceful cooperation among countries.

ORBIS tries to help developing countries by providing training during three-week medical programs. ORBIS has taught sight-saving techniques to over 3,000 doctors and nurses, who continue to cure tens of thousands of blind people every year. ORBIS has conducted 17 plan programs in China so far. For the seven to ten million blind in China ORBIS is planning to do more for them. At the moment an ORBIS is working on a long-term plan to develop a training center and to provide eye care service to Shanxi Province. ORBIS needs your help to continue their work and free people from blindness.

For just US$38, you can help one person see; for $380 you can bring sight to 10 people; $1,300 helps teach a doctor new skills; and for $13,000 you can provide a training program for a group of doctors who can make thousands of blind people see again. Your money can open their eyes to the world. Please help ORBIS improve the quality of life for so many people less fortunate than ourselves.

6 . In a major medical breakthrough, Tel Aviv University researchers have “printed” the world's first 3D vascularized (有血管的）engineered heart using a patient’s own cells and biological materials. Their findings were published on April IS in a study in Advanced Science.

“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” says Prof. Tal Dvir of Department of Materials Science and Engineering, who led the research for the study. “This heart is made from human cells and patient-specific biological materials. In our process, these materials serve as the bioinks, something made of sugars and proteins that can be used for 3D printing of complex tissue models，” Prof, Dvir says. “People managed to 3D print the structure of a heart in the past, but not with cells or with blood vessels (血管).Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future.”

According to Prof. Dvir，the use of “ native ” patient-specific materials is important to successfully engineering tissues and organs.

The researchers are now planning on culturing the printed hearts in the lab and “ teaching them to behave” like hearts, Prof. Dvir says. They then plan to transplant the 3D-printed heart in animal models.

“We need to develop the printed heart further，” he concludes. “The cells need to form a pumping ability ； they can currently contract (收缩），but we need them to work together. Our hope is that we will succeed and prove our method’s efficacy (功效)and usefulness. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world，and these procedures will be conducted routinely. ”

1. What does Prof. Dvir think of an early 3D-printed heart?

A．It was highly practical.	B．It was too expensive.
C．It was personalized.	D．It was too simple.

2. What do we know about the latest 3D-printed heart?

B．It can match a patient perfectly.

C．It has been transplanted in animals.

D．It has been widely used in hospitals,

3. What is Prof, Dvir's attitude to the development of the printed heart?

C．Disapproving.	D．Cautious.

4. What is the author's purpose in writing the text?

A．To explain the basic principle of 3D technology.

B．To introduce a breakthrough of medical research.

C．To doubt the medical value of a new invention.

D．To prove the effectiveness of the new technology.

Acupuncture refers to the practice of inserting needles into the body of a patient at a certain angle and using     7     (technique)such as twisting and lifting the needles to excite acupoints     8    (treat)diseases. Moxa-moxibustion normally refers to placing moxa(艾)directly on acupoints or holding moxa sticks at       9    distance to warm the body.

In 1995,the World Health Organization published     10     can be treated by acupuncture and moxibustion. TCM has become more and more accepted by other countries in the world.

I had always considered acupuncture (针灸) old-fashioned. But the drama of my recent strange illness and recovery changed my mind     1     (complete).

Last month, after sleeping through a flight, I discovered I couldn’t move my right arm and fingers. The doctors diagnosed me with neural (神经的) injury. I was scared. Luckily, Richard, an acupuncturist, offered     2     (help) me.

I started my acupuncture treatment. Dozens of tiny needles     3     (insert) across my arm and fingers. I dared not move, because even a small change of position could cause a sharp pain. After a few days, I could move my fingers. Two weeks     4     (go) by before I could eat a meal with chopsticks. Within a month, my arm and fingers were almost back to     5     (they) normal functions.

In that clinic, I made friends with many other patients and heard their     6     (story). One lady, who became deaf two months ago, has recovered her hearing abilities. I was very surprised at     7     magic these tiny needles are.

Acupuncture originated in China 2,000 years ago. Essentially, it functions     8     improving the smooth flow of life force energy,     9     (know) in Chinese as “qi”. Although acupuncture may not cure all illnesses, at least it creates a good starting point for a healthy body. I hope the     10     (wise) of acupuncture will continue to bring health to more friends.
