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?

【推荐1】2019-nCoV, a cousin of the SARS virus, has infected more than 10000 people since the outbreak began in Wuhan, China, in December. Scientist Leo Poon, who first decoded the novel virus, thinks it likely started in an animal and spread to humans.

“What we know is that it causes pneumonia (肺炎) and then doesn’t respond to antibiotic (抗生素) treatment, which is not surprising, but then in terms of death rate, SARS kills 10% of the individuals,” Poon, a virologist at the School of Public Health at The University of Hong Kong, said.

2019-nCoV can make people sick, usually with a mild to moderate upper respiratory tract illness (上呼吸道疾病), similar to a common cold. Coronavirus symptoms include a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a couple of days. For those with a weakened immune system, the elderly, there’s a chance that the virus could cause a lower, and much more serious, respiratory tract illness like a pneumonia orbronchitis (支气管炎).

There are a handful of human coronaviruses that are known to be deadly.

Middle East Respiratory Syndrome (中东呼吸综合征), also known as the MERS virus, was first reported in the Middle East in 2012 and also causes respiratory problems, but those symptoms are much more severe. Three to four out of every 10 patients infected with MERS died, according to the CDC.

Severe Acute Respiratory Syndrome, also known as SARS, is the other coronavirus that can cause more severe symptoms. First identified in Guangdong Province in southern China, according to the WHO, it causes respiratory problems but can also cause diarrhea (腹泻), fatigue (疲劳), shortness of breath, respiratory distress (呼吸窘迫) and kidney failure (肾衰). Depending on the patient’s age, the death rate with SARS ranged from 0-50% of the cases, with older people being the most vulnerable (易受伤害的).

Viruses can spread from human contact with animals. Scientists think MERS started in camels, according to the WHO. With SARS, scientists suspected civet cats were to blame.

When it comes to human-to-human transmission of 2019-nCoV, often it happens when someone comes into contact with the infected person’s secretions (分泌物). Depending on how virulent (有毒的) the virus is, a cough, sneeze or handshake could cause exposure. The virus can also be transmitted by touching something an infected person has touched and then touching your mouth, nose or eyes. Caregivers (护理人员) can sometimes be exposed by handling a patient’s waste, according to the CDC.

1. Which of the following can explain the underlined word “decoded”in paragraph 1?
A.found or discovered something.
B.put something into a code.
C.changed something into ordinary language.
D.changed something into a form that can be processed.
2. Which of the following statements is true?
A.Antibiotic treatment has some effect on 2019-nCoV.
B.2019-nCoV usually causes severe illness similar to a pneumonia or bronchitis.
C.Novel Coronavirus Pneumonia, MERS and SARS are all caused by corona viruses.
D.2019-nCoV spreads just by getting close to the infected person.
3. What type of writing is the passage?
A.An instruction.B.A news report.
C.An advertisement.D.A scientific paper.

【推荐2】For some people, certain foods can be deadly. Around the world, children are far more likely than ever before to develop food allergies(过敏). In the US, for example, allergy rates among children were rising from 2010 to 2016, according to the Childhood Allergies in America report. It also showed that the number of children “at risk” for a severe allergic reaction rose by 104 percent. Almost half of these severe reactions were from food.

“In the past, children often were only allergic to one or maybe two foods. But now it’s very common to see children allergic to two or three or more foods,” said Hugh Sampson, a professor at the Icahn School of Medicine at Mount Sinai, New York City, US. “And milk, eggs, sesame, peanuts, tree nuts, fish and shellfish are the common ones to take the blame.”

First of all, as countries import exotic(外来的)products, people are more likely to adopt foreign diets. One example is an increased allergy to kiwis in the US. “Everything is so global now. We’re getting exposed to foods that we never had before,” Sampson said. “And as globalization accelerates migration, more people will tend to experience food allergies.”

Environmental factors may also play a large role: Migrants appear to show a higher possibility of food allergy and asthma(哮喘)in their adopted country in comparison to their country of origin, according to the BBC.

Changes in food making could explain the global rise in allergies as well. For example, people are more likely to be allergic to dry-roasted peanuts-common in the US, UK and Australia-than boiled or fried peanuts, which are common in China. This suggests that how and when the food is introduced is as important a factor as the food itself. Food allergy awareness has increased during recent years, but there’s more work to be done to understand and deal with its rise.

1. What does the second paragraph imply?
A.More foods today can lead to allergies.
B.Food was to blame for children’s allergies.
C.Kids are more likely to suffer allergies.
D.People all know the reasons for allergies.
2. What message does the third paragraph convey?
A.Globalization has caused unexpected effects.
B.Globalization plays a role in increased allergies.
C.Globalization is the key to solving the problems.
D.Globalization allows people to experience more.
3. What is the author’s attitude towards the rise of allergies?
A.Optimistic.B.Cold.
C.Concerned.D.Disappointed.
4. What is the best title for the text?
A.Allergies increase globally.B.How to get rid of allergies?
C.What causes your allergies?D.Allergies matter a lot in life.

【推荐3】This is an outbreak of disease that started in Wuhan, one of the central Chinese cities. It’s caused by a novel corona virus that means it’s brand-new.     1    .

What are the symptoms?

The virus is from a family called the corona viruses. The symptoms of this illness are pretty mundane ( 平 凡 的 ) on the face of it: it’s a dry cough fever and then breathing problems.     2    . However, as for the more severe cases, people have gone on to develop viral pneumonia, and all the deaths have been among those people.

    3    

This brand-new coronavirus came from animals, and it’s believed that the source was actually a seafood market in Wuhan, which also sells wild animals. So far all the cases have come out of Wuhan. But somepeople haven’t picked it up there.

Should I be panicking about this outbreak?

As we can see, older people are ending up in hospital with the virus. They’re usually over 40, and the very youngest person diagnosed is about 13 or 14 years old. So it doesn’t appear to be affecting small children.     4    . Basically their immune systems are not very strong, and they’re going to find it very hard to fight off a virus.

How is this virus transmitted?

We’ve only just discovered that the new corona virus is actually transmitted from one person to another. It was hoped at first actually that it just came from animals as all corona viruses do.     5    . So we’ve got people to people transmission, because the market has been closed for sometime, and there are cases in which people who’ve never been near it.

A.It seems quite mild in lots of people.
B.Where have cases been confirmed so far?
C.So new that actually it doesn’t have a name yet.
D.People diagnosed with viral pneumonia will die.
E.It is a brand-new virus so we don’t know how it’s going to behave.
F.Those who have died tend actually to have heart disease or cancer already.
G.Now it looks as though it is actually passed from one human being to another, however.
