1 . The 90-minute documentary, Amazing China, which is co-produced by China Central Television and China Film Corp, opened in theatres nationwide.
The film focuses on the major achievements the country has made since the 18th National Congress of the Communist Party of China in 2012 under Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era.
Speaking about the documentary, Wei Tie, the director, says," The film arouses Chinese pride from deep inside."
The documentary focuses on key Chinese infrastructure（基础设施）projects in aerospace，high-speed rail，the Hong Kong-Zhuhai-Macao Bridge and the world's largest single-dish telescope FAST. The documentary also informs viewers that seven of the world's 10 biggest sea ports are now in China and that the country now has the longest high-speed rail network in the world.
In the film, Lin Ming, the chief engineer of the Hong Kong-Zhuhai-Macao Bridge project, says," In the past, what kind of projects we took up was decided by what kind of facilities we had. But, nowadays, no matter what kind of projects we are assigned, we develop the technology to complete it." His voice is calm but his words show the country’s self-confidence. Speaking of the importance of the new documentary for the Chinese, La Peikang, the head of China Film Corp, says," It's not only about showing the achievements, but presenting the present situation of China. The film will help people to know our country better."
Amazing China also focuses on common people. In the film, you see a young Tibetan woman volunteering in rural areas to help people get rid of poverty. And, you also see a successful entrepreneur from the coastal Fujian Province who settles in the Gobi Desert, in northwest China, who has taken up a new career growing grapes.

2 . A thief who dropped a winning lottery ticket at the scene of his crime has been given a lesson in honesty. His victim, who picked up the ticket and then claimed the $25,000 prize, managed to trace him, and handed over the cash. The robbery happened when maths professor Vinicio Sabbatucci, 58, was changing a tire on an Italian motorway. Another motorist, who stopped “to help”, stole a suitcase from his car and drove off. The professor found the dropped ticket and put it in his pocket before driving home to Ascoli in eastern Italy.
Next day, he saw the lottery results on TV and, taking out the ticket, realized it was a winner. He claimed the 60 million lire(里拉) prize. Then he began a battle with his conscience. Finally, he decided he could not keep the money despite having been robbed. He advertised in newspapers and on the radio, saying, “I’m trying to find the man who robbed me. I have 60 million lire for him—a lottery win. Please meet me.Anonymity(匿名) guaranteed.”
Professor Sabbatucci received hundreds of calls from people hoping to trick him into handing them the cash. But there was one voice he recognized and he arranged to meet the man in a park. The robber, a 35-year-old unemployed father of two, gave back the suitcase and burst into tears. He could not believe what was happening. “Why didn’t you keep the money?” he asked. The professor replied, “I couldn’t because it’s not mine.” Then he walked off, spurning the thief’s offer of a reward.

3 . As the effects of climate change become more disastrous, well-known research institutions and government agencies are focusing new money and attention on an idea: artificially cooling the planet, in the hopes of buying humanity more time to cut greenhouse gas emissions.
That strategy, called solar climate intervention (干预) or solar geoengineering, involves reflecting more of the sun’s energy back into space — abruptly reducing global temperatures in a way that imitates the effects of ash clouds flowing out from the volcanic eruptions. The idea has been considered as a dangerous and fancied solution, one that would encourage people to keep burning fossil fuels while exposing the planet to unexpected and potentially threatening side effects, producing more destructive hurricanes, wildfires floods and other disasters.
But. as global warming continues, producing more destructive hurricanes, wildfires floods and other disasters, some researchers and policy experts say that concerns about geoengineering should be outweighed by the imperative to better understand it, in case the consequence of climate change become so terrible that the world can’t wait for better solutions.
One way to cool the earth is by injecting aerosols (气溶胶) into the upper layer of the atmosphere. where those particles reflect sunlight away from the earth. That process works, according to Douglas MacMartin, a researcher at Cornell University.
“We know with 100% certainty that we can cool the planet,” he said in an interview. What’s still unclear, he added, is what happens next. Temperature, MacMartin said, is an indicator for a lot of climate effects. “What does it do to the strength of hurricanes?” he asked, “What does it do to agriculture production? What does it do to the risk of forest fires?”
Another institution funded by the National Science Foundation will analyze hundreds of simulations of aerosol injection, testing the effects on weather extremes around the world. One goal of the research is to look for a sweet spot: the amount of artificial cooling that can reduce extreme weather events without causing broader changes in regional rainfall patterns or similar impacts.

4 . A strong coffee after a poor night's sleep is the kick-start many people need in the morning but new research suggests that it might be best to have a bite to eat first.
A study has found that drinking coffee first can have a negative effect on blood sugar control - a risk factor for diabetes （糖尿病）and heart disease.
“We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee --- subjectively the more tired we feel, the stronger the coffee,“ said Professor James Betts, at the University of Bath in the UK.
For their study, researchers at the University of Bath got 29 healthy men and women to take part in three different overnight experiments, with at least a week between them.
In one, the participants had a normal night's sleep, roughly from 11 p.m. to 7 a.m., and were asked to consume a sugary drink on waking in the morning. They then experienced an interrupted night's sleep, where the researchers woke them every hour for five minutes by sending them text messages to which they had to respond — and upon waking were given the same sugary drink.
On another night, participants experienced the same sleep interruption, but this time were first given a strong black coffee 30 minutes before consuming the sugary drink.
They found that one night of interrupted sleep did not worsen the participants' blood sugar and insulin （胰 岛素）responses when compared to the normal night's sleep-- although previous research suggested that losing many hours of sleep or many nights of poor sleep could have a negative effect. However, strong black coffee consumed before breakfast actually increased the blood sugar response by around 50% — suggesting that relying on coffee after a bad night to stop feeling sleepy could limit your body's ability to tolerate the sugar in your breakfast.

5 . Honeybees can’t swim, and when their wings are wet, they can’t fly, either. But Chris Roh and other researchers at the California Institute of Technology found that when bees drop into bodies of water, they can use their wings to produce little waves and slide toward land—like surfers who create and then ride their own waves.
As with many scientific advances－Isaac Newton’s apple or Benjamin Franklin’s lightning bolt—Dr. Roh’s experiment began with a walk. Passing Caltech’s Millikan Pond in 2016, he observed a bee on the water’s surface producing waves. He wondered how an insect known for flight could push itself through water.
Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect local Pasadena honeybees and observed their surf-like movements. The researchers used a wire to restrict each bee’s bodily movement, allowing close examination of their wings. They found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get trapped on the surface because water is roughly three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It’s a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity.
The researchers said the surf-like movement hasn’t been documented in other insects and most semiaquatic insects use their legs for propulsion, which is known as water-walking. It may have evolved in bees, they predicted.
Dr. Roh and Dr. Gharib have imagined many practical applications for bees’ surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can’t send a boat or helicopter,” Dr. Gharib said.

6 . Killer whales, or orcas, are known for their severe attacks on sea animals but they have never posed a threat to humans. However, since late July, the normally social animals have been intentionally attacking sailboats off the coasts of Spain and Portugal.
The strange behavior first surfaced on July 29, 2020, when a 46-foot boat was repeatedly attacked for almost an hour by nine orcas, causing the boat to rotate(旋转) 180 degrees and having its engine switched off. Since then, over 30 more similar incidents have been reported. On September 23, 2020, Spain's government banned boats of less than 50 feet in length from sailing in the 60-mile stretch of the Atlantic coastline between Ferrol and the Estaca de Bares Cape, where the attacks have been occurring.
Researchers across the world are trying to explain the orcas' behavior. Some believe it could be a result of the overfishing of the bluefish tuna - the orcas' primary food source -which has left the area's killer whales starving and unable to feed their babies. "I saw them look at boats carrying fish. I think they know humans are somehow related to food shortages, "says Ken Balcomb, senior scientist at the Center for Whale Research in Washington, USA. The environmentalists believe the sudden increase in boat traffic and fishing activities, after months of absence due to restrictions on human activity last spring, could also be contributing to the agitation.
However, Alfredo López, a biology professor in Galicia, Spain, thinks the attacks are defensive measures the orcas adopted to protect themselves against boat injuries. The researcher came to this conclusion after looking at the of the videos of a few incidents and noticing that two of the young killer whales involved had serious injuries. Hopefully, the experts will be able to find a way to restore the harmony between the animals and the humans soon.

7 . Johnny Cash was born in 1932 in the southern state of Arkansas. His parents were poor cotton farmers. As a school boy, he began writing songs and he performed on radio programs. After high school, he joined the United States Air Force and served as a radio operator in Germany.
He returned to the United States in 1954 and formed a band with two friends and performed at local events. They began recording for Sun Records in Memphis. One of the songs Cash wrote became the first country music hit record for the company. It was “Cry, Cry, Cry.”
Johnny Cash performed all across the United States and Canada. By 1958, Johnny Cash was a successful recording artist, songwriter and singer. He was invited to perform at the Grand Ole Opry in Nashville, Tennessee.
Johnny Cash won many awards, including eleven Grammy Awards and the Kennedy Center Honors. He was elected to both the Country Music Hall of Fame and the Rock and Roll Hall of Fame. He also received a Grammy Lifetime Achievement Award.
He died on September 12, 2003, in Nashville at the age of seventy-one.
Fans say that Johnny Cash's music was important because it told simple stories about life and death. They say he cared about social issues and continued to express support for those who are poor and without political power. One of the last songs he recorded was one made popular by the rock and roll group Nine Inch Nails. It is called “Hurt.”

8 . “A CAREER BOOK about Asians? Aren’t they doing fine…?” So begins Breaking the Bamboo Ceiling, a very large scholarly book by Jane Hyun published in 2005. Because Asian-Americans had higher incomes and education levels and committed fewer crimes than their average countrymen, they were seen as a model minority. Despite this, they rarely rose to the top of companies. A mix of individual, cultural and organizational barriers — the “bamboo ceiling” of the book’s title — seemed to prohibit them from rising.
Fifteen years later Asians are still under-represented. In the technology sectors, Asians make up over 30% of the workers but less than 15% of bosses. In 2017 Asians made up roughly 6% of the country’s population but only 3% of the bosses of S&P 500 (标准普尔 500 指数) firms.
Some prominent Asians run big companies. Arvind Krishna is IBM’s new boss. Satya Nadella runs Microsoft and Sundar Pichai leads Alphabet. But few other Asians have joined their ranks — and, revealingly, these stars all have Indian roots. There are fewer South Asians in America than East Asians, but they still made up 13 of all 16 Asian S&P 500 CEOs.
Why are there so few Asians among America’s business elite? And if a bamboo ceiling is to blame, why do South Asians break through more easily? These questions are the focus of a study by Jackson Lu of MIT Sloan School of Management and colleagues, who surveyed hundreds of senior executives and business-school students. They found that while discrimination exists, it is not destiny. South Asians endure greater racism than East Asians but still outperform even whites (if success is weighed against share of population). Their research also rules out lack of ambition: a greater share of Asians than whites endeavor for high-status jobs.
That leaves culture. The researchers conclude that South Asians tend to be more determined and confident than East Asians in how they communicate at work, which fits Western concepts of how a leader should behave. The same tendency for confident remarks featured in “The Argumentative Indian”, a book by Amartya Sen, a Nobel-prize winning economist. The researchers owe East Asians’ silence to Confucian values of modesty and respect for social ranking. Sometimes bravery and bombast are needed to break bamboo.

9 . An electric flying vehicle called Skai was on display yesterday near Los Angeles， California． Skai is made by Alaka'i Technologies． The vehicle has six rotors（旋翼） on top． Inside， there are seats for five passengers． To many people， Skai looks like a cross between a giant drone（无人机） and a car． Alaka'i Technologies hopes the vehicle will one day serve as a flying taxi， a cargo carrier， and an ambulance．
Other companies， such as Boeing and Airbus， are also designing electric aircraft． They are using batteries to power them． But batteries can weigh the vehicles down．
Skai uses hydrogen fuel cells to power its rotors． Hydrogen fuel cells are a lighter alternative to batteries． They allow the vehicle to transport 1，000 pounds． They might also be less damaging to the environment． "It's the cleanest form of energy on the planet，" Bruce Holmes told Digital Trends， a technology news website． Holmes is on the board of Alaka'i Technologies．
A test flight will take place near the company's Massachusetts headquarters． But it may be years before the autonomous aircraft is cleared to carry passengers． Skai must first meet regulations． These regulations are set by the Federal Aviation Administration （FAA）．
"The technology is interesting， but the regulatory （监管的） road will be very long，" Thaddeus Lightfoot said． Lightfoot is a lawyer． He helps companies deal with FAA rules．
Alaka'i Technologies is hopeful that Skai will get FAA approval to fly passengers soon． In the meantime， the company's CEO， Stephen Hanvey， says the craft could be used to transport food and water． It could also serve as a mobile cell tower in places struck by natural disasters．

10 . Great work is work that makes a difference in people’s lives, writes David Sturt, Executive Vice President of the O.C. Tanner Institute, in his book Great Work: How to Make a Difference People Love. Sturt insists, however, that great work is not just for surgeons or special-needs educators or the founders of organizations trying to eliminate poverty in sub-Saharan Africa. The central theme of Great Work, according to Sturt, is that anyone can make a difference in any job. It’s not the nature of the job, but what you do with the job that counts. As proof, Sturt tells the story of a remarkable hospital cleaner named Moses.
In a building filled with doctors and nurses doing great life-saving work, Moses the cleaner makes a difference. Whenever he enters a room, especially a room with a sick child, he engages both patients and parents with his optimism and calm, introducing himself to the child and, Sturt writes, speaking “little comments about light and sunshine and making things clean.” He comments on any progress he sees day by day (“you’re sitting up today, that’s good.”) Moses is no doctor and doesn’t pretend to be, but he has witnessed hundreds of sick children recovering from painful surgery, and parents take comfort from his encouraging words. For Matt and Mindi, whose son McKay was born with only half of a heart, Moses became a close friend. As Sturt explains, “Moses took his innate (与生俱来的) talents (his sensitivity) and his practical wisdom (from years of hospital experience) and combined them into a powerful form of patient and family support that changed the critical-care experience for Mindi, Matt and little McKay.”
How do people like Moses do great work when so many people just work? That was the central question raised by Sturt and his team at the O.C. Tanner Institute, a consulting company specialized in employee recognition and rewards system.
O.C. Tanner launched an exhaustive Great Work study that included surveys to 200 senior executives, a further set of surveys to 1,000 managers and employees working on projects, an in-depth qualitative study of 1.7 million accounts of award-winning work (in the form of nominations (提名) for awards from corporations around the world), and one-on-one interviews with 200 difference makers. The results of the study revealed that those who do great work refuse to be defeated by the constraints of their jobs and are especially able to reframe their jobs: they don’t view their jobs as a list of tasks and responsibilities but see their jobs as opportunities to make a difference. No matter, as Moses so ably exemplifies (例证), what that job may be.
1. According to Sturt, which of the following is TRUE?| A．It’s not the nature of the job, but what you do that makes a difference. |
| B．Anyone in the world is responsible to delete poverty and change the world. |
| C．Anyone can make a difference in people’s lives no matter what kind of job he does. |

| C．By showing his sympathy and kindness to patients when entering their rooms. |
| D．By pretending to be a doctor or nurse when entering a room with a sick child. |
| A．demands | B．advantages | C．disadvantages | D．limitations |
| A．Great work is work that makes a difference in people’s lives no matter what you do. |
| B．If a boss has trouble recognizing his employees, he can ask O. C. Tanner for advice. |
| C．Moses makes a difference through his sensitivity and his practical wisdom. |
| D．Those who do great work are never defeated by others or their jobs themselves. |
