1 . Blind people have long desired for brightness, but scientists don’t have the technology. To bring that one step closer to reality, Zhiyong Fan, a materials scientist of the Hong Kong University of Science and Technology, developed a new artificial eye recently. The device, which is about as sensitive to light and has sharper vision and a faster reaction time than a real eyeball, may outperform human eyes.
The human eye owes its wide field of view and clear eyesight to the retina (视网膜) — an area at the back of the eyeball covered in light-detecting cells. The design for a new artificial eye is based on the structure of the human eye and uses a friendly light-sensitive material. At the back of the eyeball, an artificial retina is lined with Nan scale light sensors (纳米级光感器). Those sensors measure light that passes through the lens (晶状体) at the front of the eye. Wires attached to the back of the retina send signals from those sensors to the processor, similar to the way nerve networks connect the eyeball to the brain.
“In the future, we can use this to replace damaged human eyes,” says the lead designer. In theory, this artificial eye could see more clearly than the human eye, because the artificial retina contains about 460 million light sensors per square centimeter while a real retina has about 10 million light-detecting cells per square centimeter. Besides, the artificial eyeball records changes in lighting faster than human eyes can — within about 30 to 40 milliseconds, rather than 40 to 150 milliseconds. Although its 100-degree field of view isn’t as broad as the150 degrees a human eye can take in, the device can see as well as the human eye in poor light.
Hongrui Jiang, an electrical engineer at the University of Wisconsin, though, thinks engineers need a much more practical and efficient way to produce vast series of tiny wires on the back of the artificial eyeball to give it superhuman sight, which is super hard to achieve.

2 . With a name like The Daily Orange in America, you will think the Syracuse University student-run newspaper prints a new issue every day. The newspaper began operating at the Syracuse, New York-based school in 1903. But it only prints a new issue three times a week.
Editor in chief Haley Robertson worries about where she will find companies willing to pay for advertising space. She also worries about having to fire friends. And, she searches out former students willing to donate money so the newspaper can send reporters on the road to cover the university’s sports teams. Media executives many years older than Robertson are facing similar problems. The news industry’s financial difficulties have spread to colleges and universities across the US, which brought challenges to these young journalists. Student reporters train for the future in two main ways. They receive a traditional classroom education from professors. They also put what they learn to use in student-run newsrooms.
Chris Evans is president of the College Media Association, or the CMA. He notes that few college newspapers have shut down the way local newspapers in towns and cities across the country have, considering the central role they are playing. But some have had to cut the number of times they publish each week. Some would find a former student for donation or sell enough advertising to cover it.
The University of North Carolina reports that newspaper newsroom jobs across the country dropped from 52,000 in 2008 to 24,000 today. There are other kinds of jobs in the field, of course, but not a very high number of them. Many journalism educators have wondered whether their students can deal with that. Journalism schools should do more than just equip students for possible media jobs, said Marie Hardin, head of Penn State’s Donald Bellisario College of Communications. She said journalism educators need to teach students communication, critical thinking and writing. Such skills are highly sought in many different fields.

3 . Experienced climbers of Mount Qomolangma are wondering if new proposed rules will solve the root causes of various deadly accident on the world’s tallest mountain. The proposals, if approved by the government of Nepal, would add steps to the permitting process for mountaineers as well as limitation to tourism companies to prevent the disaster in last May happening again.
Traditionally, Nepal has given climbing permits to anyone prepared to pay a fee of $11, 000. In 2019, the government approved a record high of 381 permits. With essential Sherpas and guides added, more than 800 people were trying to reach the peak during the short weather window. The overcrowding led to deadly delays in what is known as the “death zone”, the area above 8, 000 meters, and the death of eleven climbers eventually, many of them dying in late May after they were stuck there. It also raised suspicions that guide companies were urging inexperienced or incompetent mountaineers to attempt the climb.
To reduce the potential risks, among the suggested changes is a rule for those who want to climb the Mount to have a qualified doctor prepare a report on their medical history and general health. Another is that climbers provide evidence they have climbed another tall mountain in Nepal. They will also need to be accompanied by a trained Nepalese guide.
American mountaineer Ed Viesturs said the proposed changes will likely limit the amount of climbers able to plan journeys up the Mount, yet will not do enough to stop the “group think” mentality that led to the traffic jam in late May. He said climb leaders at base camp also needed to consider how to fix the problem. “I know several climbers who waited until later and had the mountain almost to themselves,” Viesturs said of the 2019 climbing season. “We really need to answer why so many people are there on the same day? How can you control it?”
1. What is the purpose of the new proposals?| A．To attract more mountaineers. |
| B．To issue security warnings of the climb. |
| C．To guide inexperienced climbers. |
| D．To avoid death on Mount Qomolangma. |

4 . Twenty-four trains, nine countries, 13, 500 miles. They are the numbers behind the heroic round trip one man took from Southampton in the UK to eastern China.
Roger Tyers, 37, used over $2, 500, which was almost twice more than the cost of a return flight, to travel to the Chinese port city Ningbo for academic research in May, 2019. The man spent a month on board 15 trains during the first leg of his round trip. It was the climate crisis, not a love of trains, that drove the sociologist to choose this complicated route over a return flight. He stopped flying when UN climate experts warned that the world had less than 11 years to avoid terrible levels of global warming. Tyers calculated that his train journey to China produced almost 90% less emissions than a return flight.
Tyers is not the only person to avoid air travel in response to climate change. Thousands of people worldwide have publicly promised to stop flying. Activist Maja Rosen launched the “Flight Free” campaign in Sweden with the goal of encouraging 100,000 people not to fly for one year. Although only around 14,000 people signed the online “#flightfree2019” pledge (保证), Rosen, who stopped flying 12 years ago, says that the campaign had made more people worry about the climate crisis and aware of harm of travel by air and motivated them to try new ways of travelling.
According to a survey released in May 2019 by Swedish Railways (SJ), 37% of respondents chose to travel by train instead of by plane where possible, compared to 20% at the start of 2018. An SJ spokesperson said: “Rail travel has been augmented due to the worries.” Domestic passenger numbers in July fell by 12% compared to the previous year, according to Swedavia, a company which operates Sweden’s 10 busiest Airports.
“The collective pledge helps fight the sense of hopelessness many people feel when it comes to tackling climate change”, Rosen said. “One of the problems is that people feel there’s no point in what you do as an individual. The campaign is about making people aware that if we do this together, we can actually bring changes.”

5 . Canadians are blessed with an abundance of natural wonders with enough lakes, mountains and rivers to explore for a lifetime. We’ve also got some of the most amazing waterfalls on Earth.
Horseshoe Falls Niagara Falls, Ontario
Niagara Falls are the most famous waterfalls in Canada — and understandably so. Actually they are made up of three different falls, and the fittingly named Horseshoe Falls is the only one located on the Canadian side, which is the most powerful in North America. Multiple viewing options are available including tourist ships and sightseeing buses.
Nailicho (Nirginia Falls) Nahanni National Park Reserve, Northwest Territories
Coming in at twice the height of Niagara Falls, this massive waterfall is located on the South Nahanni River in the Northwest Territories. The remote location means it receives only about 1,000 visitors per year who must make their way by either boat or floatplane.
Takakkaw Falls — Yoho National Park, British Columbia
Takakkaw translated from Cree loosely means “the magnificent (壮丽的)”, and it’s a suitable word for the second-highest waterfall in Canada. After a steep drive up a winding road, Takakkaw Falls is only a short distance from the parking lot along a wheelchair accessible path.
Bridal Veil Falls — Bridal Veil Falls Provincial Park, British Columbia
Pretty and delicate, Bridal Veil Falls is located just east of Chilliwack, British Columbia, and really does look like its name, with water gently pouring over smooth rock. An easy 15-minute walk to the waterfall takes you through rich leaves. Tables are available to have a meal outdoors, and there are lots of opportunities for viewing wildlife along the way.
1. What do we know about Horseshoe Falls?| A．It is easily accessible. |
| B．It consists of three falls. |
| C．It limits tourist numbers. |

8 . UNESCO World Heritage Sites were created to celebrate and safeguard the most unique places around the world. Below are my 4 favorite UNESCO World Heritage Sites.
Cinque Terre, Italy
With cars banned here, you’ll really get to feel the unique history and character of the Cinque Terre’s five centuries-old coastal villages. The breathtaking views of harbors far below the wild coastline along with the rich colors will definitely make it a memorable holiday.
Angkor Wat, Cambodia
Angkor Wat is the world’s largest religious (宗教的) monument and it contains impressive remains from the Khmer Empire (9th to 15th century). The site has dozens of iconic temples like Ta Prohm (a magnificent temple ruin hidden in the jungle). Hosting more than two million visitors annually, this artistic masterpiece is a must-see site.
Petra, Jordan
Petra’s rock-cut architecture has contributed to its nickname, the Rose City, based on the color of the stone it was carved from. The delicate constructions of temples and tombs along with the remains of churches and temples are only a couple of reasons why this world-famous site is a must-visit destination.
Yellowstone National Park, USA
Yellowstone’s vast wilderness includes mountain ranges, lakes and waterfalls. One of the main reasons for tourists to visit Yellowstone is to observe the amazing wildlife like grizzly bear, bison, bighorn sheep wander the plains and valleys.

9 . In habitats across the planet, animals periodically drop everything to walk, fly or swim to a new place. Some animals such as whales and geese learn migration paths by following their parents. Others, including small songbirds, gain the distance and direction of their migration within their genetic code. And some animals use a combination of genetics and culture to guide their migration.
Another group of migrators does not quite fit either model, and researchers have only recently started to figure out how they find their way. The Cory’s shearwater is an oceangoing seabird that migrates over the Atlantic every year. The young do not migrate with their parents, so culture cannot explain their journeys. And the exact paths vary wildly from individual to individual, making genetics equally unlikely.
Cory’s shearwaters are long-lived, rarely producing young successfully before age nine. This leaves an opening for learning and practice to develop their migration patterns. Researchers call this the “exploration-refinement”, and until now it has been hypothetical (假设的) because of difficulties in tracking migratory animals’ movements.
But a team of researchers has done that by attaching small geolocators to more than 150 of the birds aged four to nine. They found that younger birds traveled longer distances, for longer periods, and had more diverse paths than older birds. “We finally have evidence of the ‘exploration-refinement’ for migratory birds,” says Letizia Campioni, who led the study. Younger Cory’s shearwaters are able to fly just as fast as the adults——but they do not, suggesting that the young do more exploring, which gradually fades as they mature and settle into a preferred course.
“Although it may seem less efficient than other strategies, exploration refinement could be beneficial to birds and other organisms in a rapidly changing world due to unpredictable man-made changes,” says Barbara Frei. “It might be safer to repeat a behavior that was recently successful than to rely on patterns that were perfected long ago but might no longer be safe.”

10 . Endangered polar bears are breeding (繁殖) with grizzly bears (灰熊), creating “pizzly” bears, which is being driven by climate change, scientists say.
As the world warms and Arctic sea ice thins, starving polar bears are being forced ever further south, where they meet grizzlies, whose ranges are expanding northwards. And with that growing contact between the two come increasing hybrids (杂交种).
With characteristics that could give the hybrids an advantage in warming northern habitats, some scientists guess that they could be here to stay. “Usually, hybrids aren’t better suited to their environments than their parents, but these hybrids are able to search for a broader range of food sources,” Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, told Live Science.
The rise of “pizzly” bears appears with polar bears’ decline: their numbers are estimated to decrease by more than 30% in the next 30 years. This sudden fall is linked partly to “pizzly” bears taking up polar bears’ ranges, where they outcompete them, but also to polar bears’ highly specialized diets.
“Polar bears mainly consumed soft foods even during the Medieval Warm Period, a previous period of rapid warming,” DeSantis said, referring to fat meals such as seals. “Although all of these starving polar bears are trying to find alternative food sources, like seabird eggs, it could be a tipping point for their survival.” Actually, the calories they gain from these sources do not balance out those they burn from searching for them. This could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.
“We’re having massive impacts with climate change on species,” DeSantis said. “The polar bear is telling us how bad things are. In some sense, “pizzly” bears could be a sad but necessary compromise given current warming trends.”
