Russia’s Soyuz spacecraft, which has been transporting all astronauts to and from the International Space Station(ISS)since 2011, typically carries a crew of three. However, the MS-14 capsule launched(发射)from a Russian spaceport in southern Kazakhstan on August 22, 2019, had just one passenger—a human-like robot named Skybot F-850.
The robot is the latest version of Russia’s FEDOR robots, which were initially designed to help with search and rescue efforts. Skybot is good at many human skills, including driving a car, having short conversations, and even telling jokes. But since it lacks some special sills, the spacecraft to the ISS was piloted from the ground by scientists from Russia’s space Agency. Roscosmos.
The six-foot-tall, 350-pound robot had another important task while on board. Without risking the lives of human astronauts, it helped Roscosmos researchers test the safety and flight experience of the new Soyuz-2.1, a carrier rocket, which carried the spacecraft into orbit. The feedback(反馈)will be important in determining if the rocket is safe to transport future human crews to space.
Though the launch into orbit went smoothly, Skybot’s arrival at the ISS was delayed by three days, from August 24 to August 27. The delay didn’t seem to bother the robot, which announced its arrival, “Sorry about the delay. Met with traffic. Ready to work now.”
Skybot’s two-week task is largely a test to measure its ability to work effectively in microgravity, and includes simple tasks like using tools. If all goes well, Russia hopes to send more advanced versions of the FEDOR robots to help astronauts with special tasks.
Earlier this year, the US space agency launched two little robots called Astrobees to help astronauts with daily chores, like finding lost pieces of equipment. Meanwhile, the European Space Agency’s social AI-powered CIMON spent a year assisting astronauts, before returning to Earth on August 27, 2019.
1.What is Skybot F-850 unable to do?
A.Drive a vehicle like humans. B.Conduct short conversations.
C.Say something funny to people. D.Pilot the spacecraft to the ISS.
2.How long did it take Skybot F-850 to fly to the ISS?
A.Two days. B.Three days.
C.Five days. D.Fourteen days.
3.We infer from the text that Skybot .
A.is bound to take the place of human crews
B.isn’t the first robot to help at the space station
C.worked with two other robots to assist astronauts
D.was launched to measure its security and flexibility
4.Where is the text most likely from?
A.A science experiment. B.A news report.
C.A technology guidebook. D.A research paper.

Right now in the Pacific Northwest, the local Lummi tribe is reminding us of our connection to nature, pushing us to question how we treat other species and demanding the release of a captive killer whale from Miami Seaquarium. Many local cultures have known for thousands of years that the success and sustainability of society depend upon our relationship to the natural environment have tried at great lengths to share this knowledge with us. And it's about time that we listened.
As a conservation biologist, my job is to conduct research that helps protect Earth's biodiversity. From my scientific perspective, I back the Lummi's call to release Lolita back into her native waters. Unlike other captive killer whales that were born at amusement parks, Lolita was taken directly from her native environment, which luckily has remained. This means that the likelihood of a successful reintroduction is quite high.
Why? First, because Lolita already knows how to hunt from her younger years in the Salish Sea before she was taken. Proponents of keeping killer whales captive often say that the whales are not equipped with the skills to know how to hunt and survive in the wild. This is not the case for Lolita.
Second, the fact that Lolita's family still exists and that her mother is still alive means the chances of her being accepted back into the family are quite high. In addition to their 80-year lifespans, killer whales have also been shown to long-term memories. That makes it very likely that Lolita's family will remember her and welcome her back. The fact that Lolita's mother is still alive is particularly exciting because killer whale families are matriarchal, meaning that the female members of the families largely shape the group's social structure.
From my conservationist perspective, I also back the call to free Lolita. Her family belongs to a group known as "southern resident killer whale," an endangered species whose populations are not doing well. By bringing Lolita home to the Salish Sea, we are effectively adding one more re-productively mature female into the population. If Lolita reproduces, her offspring will help maintain the wild population of wild resident killer whales.
From an ethical perspective, I support the release of Lolita because it is the right thing to do. We know that killer whales are intelligent, and that they are highly social creatures, parallel to Primates (灵长类) and yes, humans too. What does it mean for us as a society that we allow the captivity of intelligent marine mammals for our own amusement? If we cannot begin to value the diversity of life on this planet, how are we going to be able to value the diversity of life within the human race?
The release of Lolita would be a victory for the Lummi, for science-based conservation and for repairing the relationships between humans and other species. As Martin Luther King Jr. once put it, One day the ridiculousness of the almost universal human belief in the slavery of other animals will be apparent. We shall then have discovered our souls and become worthier of sharing this planet with them.
1.What does NOT contribute to the successful reintroduction of Lolita?
A.The native living environment of Lolita has remained.
B.Lolita learned the survival skills at Miami Seaquarium.
C.Killer whales have long lifespans and long-term memories.
D.Lolita's mother is still alive and plays a decisive role in the family.
2.What can be inferred if Lolita is released?
A.The ecological balance of Pacific Ocean will be disturbed.
B.The population of the endangered species may stop decreasing.
C.People will value the diversity of life within the human race.
D.The Lummi tribe may gain enormous economic benefits.
3.Which of the following shows the development of ideas in the passage?
I: Introduction P: Point Sp: Sub-point (次要点) C: Conclusion
A. B. C. D.
4.What's the main purpose of this passage?
A.To call on Seaquariums to stop using animals for entertainment.
B.To introduce the local Lummi culture to the world.
C.To support the proposal to free Lolita the killer whale.
D.To encourage people to live in harmony with animals.

Sally had anxiety disorder trouble that made her fail to speak in social situations. I’m a nurse and use Bella to help children in my community, to bring them comfort and confidence the way only a dog can. I thought back to the day when I’d first brought Bella to the school.
That morning in January, her teacher led us to a room. “Sally hasn’t spoken outside her home in two years,” she told me. “Her parents have taken her to doctors, but nothing has worked.” A little girl stood shyly just inside the doorway. Her eyes brightened when she noticed my dog.
“This is Bella.” I said. “She does tricks. Would you like to see?”
Sally nodded. I motioned with my hand. Bella lay down and then rolled over. Sally’s eyes lit up. I showed Sally the hand signals for various commands. She was a natural with Bella, maybe because she couldn’t rely on the spoken word herself. Bella sensed that and responded. Soon Sally was able to put Bella through her paces all on her own. I could see her standing taller, more sure of herself each time we met.
One morning in March when she was working with Bella, I heard a tiny voice, barely a whisper, “Good dog.” Sally didn't take her eyes off Bella, but I wanted to jump for joy. Sally spoke a little more each week, only to Bella at first, but then to me. Later, she started giving voice commands with her hand signals and her confidence rose.
Now, five-year-old Sally stood nervously in front of her kindergarten class, with Bella, my trained dog, sitting calmly by her side. All the eyes of her classmates were focused on Sally. They were waiting for her to speak. It was June—only one week of school left—but they had never heard her voice. Not once.

A walk through the galleries of Quebec's Montreal Museum of Fine Arts (MMFA) places individuals face-to-face with some 43,000 artworks ranging from Chinese ceramics (陶瓷制品) to Inuit sculpture.
While the visiting is an incredible cultural experience, a group of local physicians will soon be able to prescribe(开处方) museum visits as treatment for some illnesses.
Hélène Boyer, vice president of a Montreal-based medical association, explains that museum visits have been shown to increase levels of serotonin, a neurotransmitter (神经传导物质) known as the "happy chemical" which helps to lift mood.
According to Boyer, the small increase in hormones(荷尔蒙)associated with enjoying an afternoon of art is similar to that offered by exercise, making museum prescriptions ideal for the elderly experiencing pain that prevents them from regularly joining in physical activity.
The museum visits are designed to improve traditional methods. As Bondil notes, spending time in a peaceful environment can provide a welcome distraction. "What is most important is this experience can help them escape from their own pain," she says. "When you enter the museum, you escape from the speed of our daily life."
"I am convinced that in the 21st century, culture will be what physical activity was for health in the 20th century," said Bondil. " Some people would do well to recall that just in the 19th century, sports were believed to do harm to the body. Just as doctors now prescribe exercise, they will be able to prescribe a visit to the MMFA."
1.What does Hélène Boyer think of museum visits?
A.They can cheer people up. B.They can reduce physical activity.
C.They can slow down our life pace. D.They can increase levels of art appreciation.
2.How do museum visits affect people?
A.Stop them concentrating on pain.
B.Stop them focusing on traditional methods.
C.Encourage them not to be absent-minded.
D.Encourage them to slow their steps while walking.
3.What does the last paragraph suggest?
A.Physical activities were popular in the 19th century.
B.Sports are considered to be harmful to the body.
C.Ideas of treating illnesses are changing over time.
D.Doctors prescribe museum visits regularly now.
4.What is the main idea of the text?
A.Museum visits are ideal for the elderly. B.Happy chemical helps to lift mood.
C.Peaceful environment helps escape pain. D.Cultural activities will promote health

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components,” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic fly is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically, it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”
1.Which of the following statements was the difficulty engineers met while making the robotic fly?
A.They did not have sufficient fund.
B.No ready-made components were available.
C.There was no model in their mind.
D.It was hard for them to assemble the components.
2.What do we know about the robotic fly?
A.The robotic fly has been put into wide application.
B.The robotic fly consists of a flight device and a control system.
C.The robotic fly can collect information from many sources.
D.The robotic fly can fly well with the cooperation of individual components.
3.Which of the following can be learned from the passage?
A.The robotic fly can replace animals in some experiments.
B.Animals are not allowed in biological experiments.
C.The robotic fly is designed to learn about insects.
D.There used to be few ways to study how insects fly.
4.Which of the following might be the best title of the passage?
A.The Development of Robotic Fly
B.Robotic Fly Promotes Engineering Science
C.Harvard’s Efforts in Making Robotic Fly
D.Robotic Fly Imitates Real Life Insect

In 2016, a young British father was trampled(踩踏)to death by an elephant on the island of Koh Samui in ThaiJand. The tragedy once again raised questions over whether it is ethical to use elephants as entertainment.
For many visitors, the chance to interact with elephants is at the top of their holiday wish list. There's no shortage of opportunities to do so, from taking photos of baby elephants to riding them through the jungle, to watching them dance.
But what most visitors don't realize is elephants are involved in extremely cruel methods to make them behave. They are often kept in terrible conditions. This includes being chained up when not performing, without interaction with other elephants, a poor diet, etc. They are also subjected to training practices including beatings. Away from their natural habitat and forced to repeat the same routines day in day out, which continues throughout their dramatically-shortened lives.
Unfortunately, riding elephants is still one of the most popular tourist activities in Asia. The World Animal Protection investigated 3,000 elephants at tourist sites across Southern Asia in 2017. The study found that 77% of them were living in "severely cruel" conditions. It also found that there had been a 30% rise in the number of elephants at tourism venues in Thailand since 2010.
Many parks advertise themselves as sanctuaries (庇护所)but they aren’t. Real sanctuaries will limit contact with the elephants and visitors can only observe them from a distance most of the time.
The government needs to play a much bigger role in putting an end to elephant tourism. As travelers, please avoid any place offering riding or allowing interacting sessions with elephants. When you see abuse happening, do your bit by leaving your review on review sites and social media to warn other tourists. Many parks are now becoming ride-free as a result of pressure from tourists, the industry and the media.
1.What does the underlined word “ethical” most probably mean?
A.Safe B.Welcome C.Moral D.Available
2.What’s the third paragraph mainly about?
A.The cause of elephant tourism. B.The way of interacting with elephants.
C.The opportunities tourist can get. D.The worse condition elephants are in.
3.How does the writer support the main idea in Paragraph 4?
A.By making different comparisons B.By following the order of time and places.
C.By analyzing cause and effect. D.By giving examples and listing numbers.
4.What can we infer from the last paragraph?
A.The media and internet worked greater.
B.Riding elephants is free with tourists’ efforts.
C.Ending elephant tourism is necessary but hard.
D.Governments and tourists solved the problem together.

Exposing living tissue to subfreezing temperatures for long can cause permanent damage. Microscopic ice crystals (结晶体) cut cells and seize moisture (潮气), making donor organs unsuitable for transplantation. Thus, organs can be made cold for only a few hours ahead of a procedure. But a set of lasting new antifreeze compounds (化合物)—similar to those found in particularly hardy (耐寒的) animals—could lengthen organs’ shelf life.
Scientists at the University of Warwick in England were inspired by proteins in some species of Arctic fish, wood frogs and other organisms that prevent blood from freezing, allowing them to flourish in extreme cold. Previous research had shown these natural antifreeze molecules (分子) could preserve rat hearts at -1.3 degrees Celsius for up to 24 hours. But these proteins are expensive to extract (提取) and highly poisonous to some species. “For a long time everyone assumed you had to make synthetic (人造的) alternatives that looked exactly like antifreeze proteins to solve this problem, ”says Matthew Gibson, a chemist at Warwick who co-authored the new research. “But we found that you can design new molecules that function like antifreeze proteins but do not necessarily look like them. ”
Most natural antifreeze molecules have a mixture of regions that either attract or repel water. Scientists do not know exactly how this process prevents ice crystal formation, but Gibson thinks it might throw water molecules into push-pull chaos that prevents them from tuning into ice. To copy this mechanism, he and his colleagues synthesized spiral-shaped molecules that were mostly water-repellent—but had iron atoms at their centers that made them hydrophilic, or water-loving. The resulting compounds were surprisingly effective at stopping ice crystals from forming. Some were also harmless to the roundworm Caenorhabditis elegans, indicating they might be safe for other animals.
“These compounds are really cool because they are not proteins—they are other types of molecules that nonetheless can do at least part of what natural antifreeze proteins do, ”says Clara do Amaral, a biologist at Mount St. Joseph University, who was not involved in the research. Gibson’s antifreeze compounds will still need to be tested in humans, however, and may be only part of a solution. “We don’t have the whole picture yet, ”do Amaral adds. “It’s not just one magical compound that helps freeze-tolerant organisms survive. It’s a whole suite of adaptations.
1.What will happen if organs are kept for a long time in temperatures below zero?
A.They will have ice crystal formation inside.
B.They will not suffer permanent damage.
C.They will have longer shelf life.
D.They will be fit for transplantation.
2.What can we learn about natural antifreeze proteins?
A.They look like Gibson’s antifreeze compounds.
B.They are composed of antifreeze molecules harmless to other species.
C.They are spiral-shaped and have iron atoms at their centers.
D.They can be found in organisms living in freezing cold weather.
3.How are antifreeze molecules prevented from ice crystals?
A.By creating compounds both water-repellent and water-loving.
B.By extracting the proteins from some hardy animals.
C.By making synthetic alternatives like antifreeze proteins.
D.By copying spiral-shaped molecules mostly water-resistant.
4.What’s the main idea of the passage?
A.Push-pull chaos might prevent water molecules from turning into ice.
B.The final solution to preserving donor organs has been found recently.
C.Chemicals inspired by Arctic animals could lengthen organs’ shelf life.
D.Gibson’s antifreeze compounds can do what natural antifreeze proteins do.
