1 . It was a cold March day in High Point, North Carolina. The girls on the Wesleyan Academy softball team were waiting for their next turns at bat during practice, stamping their feet to stay warm. Eighth-grader Taylor Bisbee shivered (发抖) a little as she watched her teammate Paris White play. The two didn’t know each other well — Taylor had just moved to town a month or so before.

Suddenly, Paris fell to the ground. “Pairs’s eyes rolled back,” Taylor says. “She started shaking. I knew it was an emergency.”

It certainly was. Paris had suffered a sudden heart failure. Without immediate medical care, Paris would die. At first, no one moved. The girls were in shock. Then the softball coach shouted out, “Does anyone know CPR?”

CPR is a life-saving technique. To do CPR, you press on the sick person’s chest so that blood moves through the body and takes oxygen to organs. Without oxygen，the brain is damaged quickly.

Amazingly, Taylor had just taken a CPR course the day before. Still, she hesitated. She didn’t think she knew it well enough. But when no one else came forward, Taylor ran to Paris and began doing CPR. “It was scary. I knew it was the difference between life and death,” says Taylor.

Taylor’s swift action helped her teammates calm down. One girl called 911. Two more ran to get the school nurse, who brought a defibrillator, an electronic device (器械) that can shock the heart back into work. Luck stayed with them: Paris’s heartbeat returned.

“I know I was really lucky,” Paris says now. “Most people don’t survive this. My team saved my life.”

Experts say Paris is right: For a sudden heart failure, the single best chance for survival is having someone nearby step in and do CPR quickly.

Today, Paris is back on the softball team. Taylor will apply to college soon. She wants to be a nurse. “I feel more confident in my actions now,” Taylor says. “I know I can act under pressure in a scary situation.”

Tu Youyou is famous around the world. She is the first Chinese female scientist     1     (win)a Nobel Prize. She studied medicine at Peking University Health Science Centre. After her     2     (graduate)from university, she became a member of China Academy of Chinese Medical Sciences. In 1969, she     3     (choose)to establish a team to find a cure     4     malaria—a disease that killed millions of people every year. It was not     5     easy task. They had limited resources and they did not have enough staff. Tu Youyou studied ancient Chinese medical literature and     6     (visit)experts in traditional Chinese medicine. Then she and her team began using modern research methods to study these Chinese herbs one by one. After hundreds of failed experiments, they     7     (eventual)came across a promising chemical. The medicine they discovered was artemisinin,     8     has now become the world’s     9    (effective)drug for fighting malaria.

According to Tu Youyou, from their research experience in     10     (discover)artemisinin, they learnt the wisdom behind both Chinese and Western medicine. And there is great potential for future advances if we integrate these two kinds of wisdom fully.

5 . As the coronavirus (冠状病毒) outbreak continues, many Americans are fearful of using public transportation. They are also looking for ways to get exercise without going to a gym. So, it may not be surprising that the pandemic (疫情) has led to a major increase in bicycle sales.

In the US, bicycles at big stores have sold out. And small bicycle stores cannot keep up with demand for “family-style” bicycles: the low-cost, easy-to-ride models. “The bicycle industry is seeing its biggest sales increase since the oil crisis of the 1970s,” said Jay Townley, an industry expert. He compared the sale of bicycles to the rush to buy products like toilet paper at the start of the pandemic.

The rise in bicycle sales is not happening just in the US. Italy has created bicycle paths for the growing number of people who want to avoid public transportation. In London, city officials plan to ban cars from some central roads. Bike shop owners in Manila say demand is even stronger than what they see at Christmas time.

Of course, you can only buy a bicycle if you can find one. In the US, the shortages now mean it may take many months to get a bicycle. High demand is not the only reason for the shortage. Many bicycle factories were shut down to stop the spread of COVID-19. The increase in bicycle demand began in March as countries began to close down. In April, the sale of bicycles increased 200 percent in the US.

Joe Minutolo is the co-owner of Bar Harbor Bicycle Shop in Maine. He said he hoped the increased sales meant a change in the way people think about transportation. “People are having a chance to rethink things,” he said, “Maybe we’ll all learn something out of this, and something really good will happen.”

1. What causes the increase in bicycle sales?

A．Shortage of public transportation.

B．Outbreak of the coronavirus.

C．People’s desire to defeat disease.

D．People’s fear of natural disasters.

2. What change has the pandemic caused in Italy?

A．More bikes are sold than at Christmas time.

B．“Family-style” bicycles are in great need.

C．Cars are banned from some central roads.

D．New bicycle paths have been built.

3. What can we know from Paragraph 4?

A．It’s impossible to buy a bike.

B．Bike factories were closed in April.

C．High demand for bikes began in March.

D．It takes many months to produce a bike.

4. What is Joe Minutolo’s attitude towards the increased sales of bicycles?

D．Critical.

6 . 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.

1. What is the author’s main purpose in writing this article?

A．To explain what makes a modern-day hero.

B．To praise medical staff for their efforts to fight the NCP.

C．To describe what measures China has taken to deal with the virus.

D．To show the difficulties faced by medical staff treating NCP patients.

2. What do we learn from Zhang Dingyu’s words?

A．His illness has turned him into an impatient man.

B．His illness makes him work without fear.

C．He feels sorry for himself because of his illness.

D．He wants to help as many patients as possible.

3. Why doesn’t Lu Jingjing answer her parents’ video calls?

A．She is too busy and has no time for video chats.

B．She doesn’t want her parents to worry about her.

C．It’s not allowed to make a video call from the hospital.

D．There is no WiFi signal at the temporary mobile hospital.

4. The underlined word “manifestations” in the second-to-last paragraph probably means “_______”.

A．results	B．differences
C．indications	D．advantages

7 . The COVID-19 and flu are both respiratory infectious diseases, with similar symptoms including fever and cough, but they are not the same.

Both the COVID-19 and flu are diseases caused by a virus. In the case of flu, the pathogens(病原体) are flu viruses, and for COVID-19, it is a novel coronavirus(新型冠状病毒).

Common symptoms for flu and novel coronavirus are nearly identical fever, cough and tiredness, sometimes sore throat and diarrhea. In severe cases, they result in pneumonia(肺炎), and even deaths in the worst cases. Flu has seasonal ups and downs. Although it can exist all year round, the virus infects more people in winter and spring. As for the novel coronavirus, there is not yet enough evidence showing how it would                    respond to changing weather.

The mortality rate(死亡率) for the novel coronavirus is higher than that for flu. Generally, people with poor immunity(免疫力), especially children and seniors, are more likely to catch seasonal flu and develop into severe cases. As for the novel coronavirus, the median age for the infected is 51. But the novel coronavirus is a brand-new virus, and no one has total                    immunity no matter their age.

Both the flu and the novel coronavirus are transmitted in similar ways, by direct contact with infected patients or small droplets from the nose or mouth when a person with viruses coughs or breathes.

Flu can be spread by an infected person for several days before their symptoms appear. As for the novel coronavirus, spread might be possible before people show symptoms, but this is not thought to be the main way the virus spreads.

For the novel coronavirus, there is also a risk for aerosol transmission(气溶胶传播). In health facilities, people may catch the virus if they breathed in aerosol, the suspension of fine solid or liquid particles in the air, which have been contaminated by the virus. The novel coronavirus has also been found in patients' fecal(排泄物) samples, but fecal-oral transmission does not appear to be a major transmission route.

1. What can we learn about the novel coronavirus?

A．It has seasonal changes.

B．It causes less deaths than flu.

C．It may spread among people of all ages.

D．It only spreads after people show symptoms.

2. Which of the following is NOT the way the novel coronavirus transmits?

A．Aerosol transmission.

B．Contact transmission.

C．Fecal-oral transmission.

D．Age transmission.

3. The author's main purpose of writing the article is probably to .

A．prove flu has less harm to humans than COVID-19

B．raise people's awareness of protecting their health

C．prove COVID-19 probably won't cause human deaths

D．provide some suggestions to avoid COVID-19 infection

4. What does the passage mainly talk about?

A．A new treatment on the novel coronavirus.

B．The latest research on COVID-19 and flu.

C．The difference between the novel coronavirus and flu.

D．How to identify COVID-19 and flu on symptoms.

8 . 阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

The Montreal Museum of Fine Arts in Canada has organized a group of doctors to help sick people in the past few months. The doctors will send patients to art galleries, instead of     1    (give) them medicine. The museum is involved in ten experiments on patients to find out how art has an effect     2     health. The patients include people with breast cancer (乳腺癌), eating disorders and mental health     3     (problem). Thomas Bastien, director of education and wellness at the museum, believes that art can heal. He said, “We saw that the museum was good for people, so we     4     (decide) to start this program with the doctors a few months ago. If you have breast cancer, you can come to the museum and you might feel much     5     (well)”.

Dr Helene Boyer,     6     has a lot of experience in helping to heal people with art treatment, spoke about its advantages. She said, “There’s more and more scientific evidence that art treatment is good for your physical health.” She said that looking at art increases     7     same kinds of hormones (激素) in our bodies that     8     (produce) when we exercise. The museum’s director-general said, “I am     9     (complete) sure that in the 21st century, art will be what physical activity was for health in the 20th century. I am very     10     (confidence) in it.”

9 . Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. You won’t feel any immediate effects, but sitting for long periods of time will hurt you forever.

Crossing your legs can also lead to neck and back pain. Ideally, it’s best for our bodies to sit with our feet planted flat, hip width apart, on the floor, but it’s not easy to maintain perfect posture all day at the office. When you sit with your legs crossed your hips are in a twisted position, which can cause one of your pelvic bones(骨盆) to rotate. Since your pelvic bone supports your neck and spine（脊椎）, this can cause pressure on your lower and middle back and neck.

You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful or have the feeling of being asleep. This is because when one leg sits on top of the other it causes pressure on the veins（静脉） and nerves in your legs and feet. It can cause numbness and/or temporary paralysis in the legs, ankles, or feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

1. Which of the following is not the consequence of crossing legs?

A．Neck and back get hurt.

B．Feet and legs become numb.

C．Blood pressure goes up.

D．Pelvic bones keep perfect postures.

2. What does the underlined word “rotate” in Para3 mean?

A．break seriously

B．hurt greatly

C．move casually

D．straighten suddenly

3. What does the text mainly talk about?

A．How to choose a proper sitting posture

B．It is advisable not to sit with legs crossed

C．How to develop beneficial habits

D．Blood pressure harms our bodies.

10 . For a lot of people, getting a full night's sleep is nothing more than just a dream. Some of us climb into bed in the early evening, and the next thing we know, it's 2 in the morning and we're still staring at the ceiling. It's common knowledge that sleep problems can be caused by things such as stress, anxiety, or even using a smart phone before bedtime. But recently, a team of researchers discovered that genes could also be a cause of sleepless nights.

The scientists, from The Rockefeller University in New York, US, found that DSPD, delayed sleep phase disorder（睡眠时相延迟综合征）, a condition that affects one's sleeping patterns, is passed down by a mutated gene（发生变异的基因）. DSPD sufferers wake up later and go to bed later than the average person. To come to their conclusion, the team studied a 46-year-old woman who is only usually able to fall asleep at 2 or 3 in the morning. It was discovered that the woman's body produces the hormone（激素） that helps her sleep at night up to seven hours later than regular sleepers. The scientists found this is caused by a mutation in one of the woman's genes, one that helps regulate the “body clock”.

Some of the woman's family members were also found to share the same mutation — and the same sleeping problems — leading the scientists to believe that sleep troubles are passed down through the generations.

However, having this mutation doesn't mean you automatically have sleep problems. The team also found two people who had the mutation but reported no problems with their sleep.

But while this is an interesting discovery, it offers no help to those who can't fall asleep at night — although there are a few things you could try to help yourself sleep earlier.

BBC journalist Michael Mosley produced a TV documentary in May in which he talked about his battle with insomnia（失眠）and the techniques he used. “I avoid social media for at least an hour before bed, I do mindfulness exercises, and if I wake up in the middle of the night, I read a book for an hour or so,” he wrote in an article for the Radio Times.
