题目内容

【题目】 It was a Saturday evening in Marchjust before sundownwhen we heard the screaming. I was out walking with my wifeMelissaand our golden retriever(猎犬)Kirabeside a lake when the peace was broken by a woman’s voicecalling out two names over and over.

We spotted heralmost immediatelythree or four hundred feet away across the lake. Spring had come but there was still snow on the groundthe water covered by a layer of ice that had just started to thaw. Two big dogs were walking across it. They appeared to be quite old and were moving slowly. As we watchedthe ice gave way beneath one dog and then the otherplunging them into the water.

We arrived at the scene a few minutes laterbut the dogs already seemed to be showing the effects of the cold as they struggled weakly to escape. We realized that calling 911 would be useless—the dog farther out was in water about 20 feet deep and I feared neither of them would stay afloat long enough for the emergency services to arrive. BesidesI was probably qualified to carry out the rescue myself. I was practicing the kind of deep breathing my grandfather had taught me as I walked in. I wasn’t alone—Kira swam alongside me. Having Kira there was a huge support. We were able to go back to shore quickly.

The second dog was further out and I had to pause before I went back in. That’s when another technique I’d learned from my grandfather came into play. He’d taught me about a pressure point on the wrist that when pressed in the right way sends out an electrical signallike a jolt of energy. That kept me warm as I set out again withKira. I maintained eye contact with the dog as we approached. With Kira’s encouragementit followed us back. The owner was emotional—“I’m the luckiest woman alive!”she said.

1What does the underlined word“thaw”in Paragraph 2 probably mean?

A.Melt.B.Shake.

C.Flow.D.Appear.

【题目】 Even in the best and most loving of times, families can feel impossibly confined (受限制的). Teens are irritable and furious. Parents are annoying and embarrassing. For Esther and her daughter Chaya, the tiny new coronavirus changed all that.

Esther was born in Wuhan-a dynamic and culturally rich place that she deeply loves but moved to the U.S. During the winter holiday, they went to Wuhan to visit Esther’s parents. Gradually at first, then more frequently, they noticed face masks on city streets. To be safe, they wore their own masks and stopped going to public gatherings. Then, suddenly the city was on lockdown. No one could leave. Their reservations home on a China Southern airlines flight were worthless. “I feared for my daughter’s life,” said Esther, “If it got worse, there could be chaos. She doesn’t speak much Chinese.”

For days, Esther repeatedly called and emailed for help. It was nonstop. She stayed online, checking all the time. Chaya felt distressed and helpless. It's awful seeing her mother go through that-without having anything she could do to help in the hotel.

Their luck changed with one email. For the 1,000 Americans stuck in Wuhan, there were 230 available seats on one outbound flight, it said. Esther bought two $1,100 seats. After a 12-hour wait at the airport, they got clearance to leave, and arrived at March Air Force Base, where they were isolated in two small connected rooms with a shared bath for two weeks. There were daily medical checkups, twice daily temperature checks and a 10 a m. briefing (简报). But there was no WiFi, TV or friends. For emotional support, Esther phoned her husband Haim, an engineering manager for Uber, and their two other children, ages 13 and 11.

Now home, they are basking in (沉浸于) the thrill of phone calls, TV interviews and a caring community. They’ve gotten little sleep. Suitcases remain unpacked. But anyhow, they have survived not just the outbreak of a virus but the unforgettable experience of mother-daughter togetherness.

1What can be inferred from the second paragraph?

A.The culture and vitality of Wuhan have attracted Esther and Chaya there.

B.The virus has affected people's life in Wuhan.

C.The flight of going back to the U.S. has been postponed.

D.The city was locked down because it was in chaos.

2What caused Chaya's depressed mood?

A.Seeing her mother suffer from reaching out for help.B.Being kept in Wuhan for poor health.

C.Missing her family and friends at home.D.Being unable to speak Chinese.

3Why were they isolated after Esther and Chaya arrived at the airport?

A.The concern of their safety as well as the public’s.

B.Their infection of the virus.

C.The lack of flight home.

D.Their emotional problems after the experience.

4What is the best title of the text?

A.Life in Wuhan: fighting the virus together.

B.Life about people infected by the virus.

C.Life about a mom and teen united by a virus.

D.Life about a mom and daughter from the U.S.

Driverless cars used to be the sort of thing you’d see in sci-fi films, but in 2020 they’re becoming a reality. Autonomous car technology is already being developed by the likes of Lexus, BMW and Mercedes, and we’ve even tested Tesla’s driverless Autopilot system on UK roads. Across the Atlantic, Google is developing its automated technology in the wild, and Apple is rumoured to be working with BMW on its own-probably automated-car.

Fully-driverless tech is still at an advanced testing stage, but partially automated technology has been around for the last few years. Executive saloons like the BMW 7 Series feature automated parking, and can even be controlled remotely.

With so much investment and interest in driverless technology, it’s easy to assume that self-operating cars are likely to happen soon, but they’re much further away than we might think. Before driverless vehicles go to market widely, manufacturers must deal with a range of technical and ethical challenges, and prevent the biggest threat to autonomous technology: humans.

The human problem

Humans present problems for autonomous cars as both drivers and pedestrians, and dealing with our unpredictable behaviour represents a significant challenge for the technology.

The Google Car is one of the most experienced autonomous vehicles. Even so, its interaction with human drivers has given rise to the exposure of one of driverless cars’ main weaknesses. The first injury involving the Google Car wasn’t due to a fault in its system, but human-error. While correctly waiting at traffic lights, Google’s self-driving car was hit by an inattentive driver and, in spite of its sophisticated array (复杂精密的数组) of sensors, there was little it could do to avoid the incident. Luckily, the accident only resulted in minor injury for a few of the passengers, but it’s a reminder that autonomous cars are at risk when surrounded by human road users.

Despite their sophisticated systems, self-driving cars currently have no plan B for human road users. Human drivers are able to interact with each other and make allowances, but also make countless, small mistakes when driving-mistakes to which current self-driving cars simply can’t adapt.

Dealing with pedestrians

The way human drivers interact with pedestrians raises difficult moral and ethical questions for car manufacturers-with implications.

Autonomous cars need to understand the way pedestrians behave, while also imitating the behaviour they’d expect from a human driver. “Everyone has a knowledge of how a human being is going to react, because we are all human beings,” says computer ethics commentator Ben Byford. “So if you walk out in front of a car, and presumably the car driver knows you’re there, they’re going to react in a certain way.”

“ If I walked out in front of a Google car travelling at 60mph, I have no real knowledge of how the vehicle will behave, so I’m effectively putting myself in danger.”

How 1 away are we from autonomous cars?

Background information

Autonomous car technology has been 2 in some famous car manufacturers.

Partially automated technology has been in 3 for the last few years.

Before our roads are 4 with driverless vehicles, manufacturers have a lot of things to do.

5 about the autonomous technology

The human problem

The Google car’s accident has 6 one of driverless cars’ weaknesses.

7 the sophisticated array of sensors, Google’s self-driving car could do little to avoid the accident.

With no alternative plan, self-driving cars cannot have a good 8 with human drivers.

Dealing with pedestrians

9 human drivers who know pedestrians well, autonomous cars have difficulty in 10 their behavior, thus putting pedestrians in danger.

【题目】 Over a four-year period, Swiss researchers have developed a machine that can keep human livers ()alive outside of the body for one week.

Livers are among the most commonly transplanted (移植)human organs. Current technology can only keep human livers alive for up to 24 hours. It is reported that, in 2017, about 8.000 liver transplants were performed in the U.S., of which 360 used livers from living givers In addition, about 11,500 people were registered on a waiting list to receive a liver transplant. Keeping livers alive and functioning for longer periods could greatly improve the chances of survival for patients.

The researchers say the purpose of their “Liver4Life” machine is to perform what they call liver perfusion (灌注)operations outside of the human body. Perfusion is the process by which blood or other liquids are pumped through organs and tissue. The machine keeps the liver at the right temperature and moves it in a way that would be natural in the body. Using a pump to fill the liver with blood acting like a human heart, the machine also provides oxygen to the organ, controls red blood cell levels and removes waste.

The research team began their experiments with livers from pigs. After repeated testing and engineering development, they succeeded in getting the pig livers to survive for seven days with support only provided from the Liver4Life machine. They also discovered the system can work to repair damaged livers. The team is now planning its next step to transplant machine-treated organs into patients.

Pierre-Alain Clavien. leader of the research said in a statement. “This technology will greatly increase the number of livers available for transplant, improving the chances of survival for patients. The success of this unique machine opens the way for many new applications in transplantation and cancer medicine.”

1What does the author intend to do in paragraph 2?

A.Introduce a brand new topic for discussion.

B.Provide some latest data about present liver transplants.

C.Show the urgency of tech improvement in liver transplants.

D.Remind readers concerned of the importance of a healthy liver.

2What does the underlined word “it” in paragraph 3 refer to?

A.The machine.B.The liver.

C.The temperature.D.The tissue.

3What can we learn about the Liver4Life machine?

A.It is among the most commonly used machines for liver transplants.

B.It is aimed to carry out liver perfusion operations in the human body.

C.It can perform several functions to keep the liver working normally.

D.It can be used to keep the pig livers alive for more than one week.

4Where is this text most likely from?

A.A biology textbook.B.A first aid brochure.

C.A social web page.D.A health magazine.

【题目】 Algorithms (算法) affect nearly every part of a person's experience on the Internet. Search engines are most people' s entry to the Internet.If a person wants to find information about something, they usually start with a search bar.As soon as they start typing or choosing links,the algorithm starts gathering data about every choice users make and uses that data to try to find the websites or information that most directly relate to what the user is looking for.

The problem with algorithm is that they can limit the kinds of information people see,says MacMillan,a reading researcher with Project Information Literacy (能力). He argues this can be harmful to people's critical thinking and lead them to believe that only one point of view is correct.

Companies also pay to post advertisements for products that could relate to users' search data. For example,if you search for places to take a vacation,you will likely start to see ads for travel companies, flights or hotels.

Renee Hobbs, director of the Media Education Lab at the University of Rhode Island, however, argues that algorithms are not all bad. She says search engine algorithms can help you find what might be the most useful information faster. But she says it is in the interests of Internet companies to keep users on the Internet for as long as possible so they see more ads.

The current generation of young people grow up using the Internet and they are prone(易于遭受) to distrustful information.That is why schools must train students how to use the Internet more wisely in their Studies.It is the duty of education to keep students informed about the world around them. Yet it is not the duty of education alone. And lawmakers should consider increasing data protection rules. Individuals can also use a wide variety of websites to avoid algorithmic controls.

1How do algorithms affect users' Internet experience?

A.They lead to slower Internet connection.

B.They block ads for users automatically.

C.They always help users get reliable links.

D.They determine the content users receive.

2What is Hobbs' attitude to algorithms?

A.Doubtful.B.Supportive.

C.Objective.D.Indifferent.

3What can be concluded from the last paragraph?

A.Young people fall victim to the Internet.

B.Data protection rules are already enough.

C.Education is fully responsible for algorithmic controls.

D.Joint efforts are needed to handle algorithmic controls.

4Which column of a magazine is the text most likely from?

A.Science.B.Entertainment.

C.Advertisement.D.Fashion.
