1 . 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.

2 . Hardware in general, and smartphones in particular, have become a huge environmental and health problem in the Global South’s landfill sites(垃圾填埋场).
Electronic waste (e-waste) currently takes up 5 percent of all global waste, and it is set to increase rapidly as more of us own more than one smartphone, laptop and power bank. They end up in places like Agbogbloshie on the outskirts of Ghana’s capital, Accra. It is the biggest e-waste dump in the world, where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process. They risk their health searching for the precious metals that are found in abandoned smartphones.
But Agbogbloshie legally should not exist. The Basel Convention, a 1989 treaty, aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries. The e-waste industry, however, circumvents regulation by exporting e-waste labelled as “secondhand goods” to poor countries like Ghana, knowing full well that it is heading for a landfill site.
A recent report found Agbogbloshie contained some of the most dangerous chemicals. This is not surprising: smart phones contain chemicals like mercury(水银), lead and even arsenic(砷). Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certain chemical which can cause cancer and damage the immune system at a level that’s about 220 times greater than a limit set by the European Food Safety Authority (EFSA). Most worryingly, these poisonous chemicals are free to pollute the broader soil and water system. This should concern us all, since some of Ghana’s top exports are cocoa and nuts.
Some governments have started to take responsibility for their consumers’ waste. For example, Germany has started a project that includes a sustainable recycling system at Agbogbloshie, along with a health clinic for workers. However, governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware, especially when governments’ green policies are focused on issues like climate change.
Only the manufacturers can fix this. A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable, or at least cost-neutral.
1. What can we infer from Paragraph 2?| A．Electronic waste requires more landfill sites. |
| B．Electronic waste is too complex to get fully recycled. |
| C．Electronic products need to be improved immediately. |
| D．Electronic pollution is a burning question in Agbogbloshie. |

| A．The violation of EFSA’s standards. | B．The threat of polluted food worldwide. |
| C．The lack of diversity in Ghana’s exports. | D．The damage to chicken’s immune system. |
| A．Letting governments take on the main responsibility. |
| B．Reducing customers’ demands for electronic products. |
| C．Governments adjusting their green policies about e-waste. |
| D．Manufacturers’ developing a sustainable hardware economy. |
3 . Vincent Van Gogh (1853-1890) is one of the most popular of the Post-Impressionist painters. He is famed for the great vitality of his works which are characterized by expressive and emotive use of brilliant color and energetic application of impastoed (厚原料的) paint.
Below are some famous pictures painted by Vincent and the poetic lyrics(歌词) to Don McLean’s hit song Vincent (Starry, Starry Night) in the famous cartoon film 《Loving Vincent》 .
| Vincent Starry, starry night, Paint your palette(画板) blue and grey, Look out on a summer’s day, With eyes that know the darkness in my soul. Shadows on the hills, Sketch the trees and the daffodils, Catch the breeze and the winter chill, In colors on the snowy linen land. Now I understand What you tried to say to me How you suffered for your sanity(精神正常) How you tied to set them free. They would not listen They did not know how Perhaps they'll listen now. Starry, starry night. Flaming flowers that brightly blaze, Swirling clouds in violet haze(阴霾,疑惑), Reflect in Vincent’s eyes of china blue. Colors changing hue, morning. field of amber(黄色的) grain, Weathered faces lined in pain, Are soothed(抚慰) beneath the artist’s loving hand. For they could not love you, But still your love was true. And when no hope was left in sight On that starry, starry night, You took your life, as lovers often do. But I could have told you, Vincent, This world was never meant for one As beautiful as you. Now I think I know what you tried to say to me, How you suffered for your sanity, How you tried to set them free. They would not listen, They're not listening sill Perhaps they never will… |

4 . The view from the top of Marina Bay Sands, a giant hotel, mall and casino, takes in the skyscrapers of Singapore, the fleets of ships entering and leaving the city's ports, the scattered tropical islands of the Singapore Strait and the crowds of soggy but determined selfie- takers trying to capture a perfect image of it all from the enormous infinity pool. Among the celebrities the hotel has lured (吸引) for a damp snap are Jing Boran and Fu Xinbo, Chinese film and music stars. China Daily, a Chinese state-owned newspaper, has declared the spot the eighth most romantic in the world. The place displays itself all over Chinese social media and offers special discounts and packages to visitors from China.
Such spin is increasingly important. Last year, for the first time, China was the biggest source of tourists to Singapore, accounting for 3. 2m of its 17. 4m visitors. Between January and September alone they spent more than $3bn ($ 2.3bn).
All across South-East Asia， tourism is booming. The number of visitors jumped by 49% between 2010 and 2015， to more than 109m. Tourism in Asia and the Pacific is growing faster than anywhere else in the world. The region receives a quarter of the world's holidaymakers (Europe’s share is still a half).
South-East Asia’s Edenic islands, ancient temples and delicious food are strong enticements (诱惑，怂恿). Visitors also flock to countries with cheap currencies: the weakness of the ringgit last year helped draw visitors to Malaysia, for example. Many countries in the region depend on the cash: tourism accounts for about 28% of Cambodia’s GDP and more than 20% of Thailand’s.
The most remarkable growth has been in tourists from China. The number visiting South-East Asia has increased fivefold over the past decade. Newly wealthy Chinese spent almost $ 26lbn travelling abroad in 2016, up from $73bn in 2011.
Indonesia, for one, has relaxed its visa rules to attract more of them. More seats on cheap flights have also helped pull in tourists: between 2013 and 2016 the number available each week on flights to South East Asia from China increased from 92,000 to 188,500.
But for the frenzied holidaying to continue to grow, infrastructure must improve, reckons Paul Yong of DBS, a Singaporean bank. Airports in places such as Manila and Jakarta are crumbling and surrounded by snaking traffic. Plans are afoot to increase annual capacity at Bangkok’s airports by tens of millions over the next four years. Hanoi’s Noi Bai will be expanded at a cost of $5.5bn to accommodate 35m passengers by 2020. Airports in Singapore and Kuala Lumpur are to be upgraded too.
Other threats to thriving tourism are far harder to plan around, Travel operators tremble at the thought of economic downturns, volcanic eruptions and epidemic diseases. The head of one luxury holiday company says the regional outbreak of SARS, a respiratory disease, more than 15 years ago almost brought the industry to its knees. Political spats between China and its neighbours are another problem. So too is the manner in which Chinese visitors have been vilified in the region for snaffling prawns at buffets, barging into queues and misbehaving on planes. It makes many of them feel unwanted. But given that just 135m of China's 1. 4bn people have ever travelled abroad, South East Asian countries should prepare to welcome many more Chinese — even when they clog up the infinity pool.

5 . The brain has a powerful ability to remember and connect events separated in time. And now, in that new study in mice published in Neuron, scientists at Columbia’s Zuckerman Institute have cast light on how the brain can form lasting links.
The hippocampus-a small, seahorse-shaped region buried deep in the brain-is an important headquarters for learning and memory. Previous experiments in mice showed that disruption (中断) to the hippocampus leaves the animals with trouble learning to associate two events separated by tens of seconds.
“The traditional view has been that cells in the hippocampus keep up a level of continuous activity to associate such events,” said Dr. Ahmed, co-first author of the study. “Turning these cells off would thus disrupt learning.”
To test this view, the researchers imaged parts of the hippocampus of mice as the animals were exposed to two different stimuli (刺激物): a neutral (神经的) sound followed by a small but unpleasant puff of air. A fifteen-second delay separated the two events. The scientists repeated this experiment across several trials. Over time, the mice learned to associate the sound with the soon-to-follow puff of air. Using advanced microscopy, they recorded the activity of thousands of neurons (神经元) , a type of brain cell, in the animals’ hippocampus over the course of each trial for many days.
“We expected to see continuous neural activity that lasted during the fifteen-second gap, an indication of the hippocampus at work linking the auditory sound and the air puff,” said computational neuroscientist Stefano Fusi, PhD. “But when we began to analyze the data, we saw no such activity.” Instead, the neural activity recorded during the fifteen-second time gap was sparse (稀少的). Only a small number of neurons worked, and they did so seemingly at random.
To understand activity, they had to shift the way they analyzed data and use tools designed to make sense of random processes. Finally, the researchers discovered a complex pattern in the randomness: a style of mental computing that seems to be a remarkably efficient way that neurons store information.
“We were happy to see that the brain doesn’t maintain ongoing activity over all these seconds because that’s not the most efficient way to store information,” said Dr. Ahmed. “The brain seems to have a more efficient way to build this bridge.”
In addition to helping to map the circuitry involved in associative learning, these findings also provide a starting point to more deeply explore disorders, such as panic and post-traumatic stress disorder.

6 . Are you aware that every single person on this planet who has ever lived, lives now or will live, has a different perception of reality? The way each of us perceives the world is to some degree different than any other person's perception of reality. __①__ What is absolutely real and right for you may be an illusion, or nonexistent, or completely false for another!
It's important to know this. __②__ For example, the news media loves to create drama, and one of their favorite methods is to elicit(引起) fear: fear of other people, fear of the weather, fear of the economy, etc. The news media tells us how to perceive the world—and if a person takes the newscasters at their word, they perceive the world to be very dangerous and hostile. To that person，the mental images and emotions suggested by other people create a version of reality that is completely different from the reality perceived by someone who does not watch the news.
Things are not always what they seem. For most people, seeing is believing, which is why magicians, artists and marketers are so successful. Just like the TV news, they show you only what they want you to see and it is perceived as reality. But how would that reality change if you saw what went on behind the scenes or what was left out?
What's your story?
We all have a story. Over time, your story takes on a life of its own and you become your story. But who's the author and why did him put so much crap in there? All that unnecessary suffering, struggle, heartache, worry and pain... wouldn't it be better to live a story without all that? Who wants to live in a story with that much boredom and unfulfilled longings?
The story got its start when you were born, and was coauthored by you along with the influences in your life. __③__ Anytime you were influenced by someone or something, you unconsciously handed your pen over and said “Here, you write this about me.” So you are not even writing your OWN story! No one does—until they recognize that fact, and make a conscious decision to take control of the pen. You CAN write your story the way you want it to play out.
________________
It is helpful to understand how the brain takes reality and filters it to create your unique perception of reality. It's an automatic unconscious action that is based on：
● Physical experiences (which is why some optical illusions are extremely unsettling)
● Past conditioning (how you are programmed to see the world)
__④__ When you become aware of the fact that you are constructing your own reality, you can take charge and build one that is more pleasing. If you change your mind, your vibration and your intentions, you can change your circumstances! Instead of, “I am a victim of circumstance，” imprint in your mind, “I am the cocreator of my life”； Instead of, “I am sick and tired of...” imprint in your mind，“I am in control and enthusiastic about what I do”．
Raise your vibration by thinking, talking and acting more positively. As positiveness becomes a mental habit，that change will become your new inner reality, which will soon manifest in your outer reality.
The power of perception is immense. Choose to see more good than bad, more abundance than lack, more love than indifference and more success than struggle.

7 . Not too many decades ago it seemed “obvious” both to the general public and to sociologists that modern society has changed people’s natural relations, loosened their responsibilities to kin (亲戚) and neighbors, and substituted in their place superficial relationships with passing acquaintances. However, in recent years a growing body of research has revealed that the “obvious” is not true. It seems that if you are a city resident, you typically know a smaller proportion of your neighbors than you do if you are a resident of a smaller community. But, for the most part, this fact has few significant consequences. It does not necessarily follow that if you know few of your neighbors you will know no one else.
Even in very large cities, people maintain close social ties within small, private social worlds. Indeed, the number and quality of meaningful relationships do not differ between more and less urban people. Small-town residents are more involved with kin than are big-city residents. Yet city dwellers compensate by developing friendships with people who share similar interests and activities. Urbanism many produce a different style of life, but the quality of life does not differ between town and city. Nor are residents of large communities any likelier to display psychological symptoms of stress or alienation, a feeling of not belonging, than are residents of smaller communities. However, city dwellers do worry more about crime, and this leads them to a distrust of strangers.
These findings do not imply that urbanism makes little or no difference. If neighbors are strangers to one another, they are less likely to sweep the sidewalk of an elderly couple living next door or keep an eye out for young trouble makers. Moreover, as Wirth suggested, there may be a link between a community’s population size and its social heterogeneity (多样性). For instance, sociologists have found much evidence that the size of a community is associated with bad behavior including gambling, drugs, etc. Large-city urbanities are also more likely than their small-town counterparts to have a cosmopolitan(见多识广)outlook, to display less responsibility to traditional kinship roles, to vote for leftist political candidates, and to be tolerant of nontraditional religious groups, unpopular political groups, and so—called undesirables. Everything considered, heterogeneity and unusual behavior seem to be outcomes of large population size.

8 . Deo had grown up barefoot in Burundi, but for a peasant boy he had done well. He was twenty-four. Until recently he had been a medical student, for three years at or near the top of his class. But he had spent the past six months on the run.
He had one friend who had seen more of the world than East Central Africa, a fellow medical student named Jean. And it was Jean who had decided that New York was where he should go. Deo was traveling on a commercial visa. Jean’s French father had written a letter identifying Deo as an employee on a mission to America. He was supposed to be going to New York to sell coffee. Deo had read up on coffee beans in case he was questioned. Jean’s father had also paid for the plane tickets. A fat book let of tickets.
He had heard of French soldiers behaving badly in Rwanda, and had even caught glimpses of them training militiamen(民兵) in the camps, but waking up and seeing a white person in the next seat wasn’t alarming. No one called him a cockroach (蟑螂). No one held a machete (大砍刀).
A voice was speaking to him. He turned and saw a policeman who seemed friendly. Deo spoke to him in French, but the man shook his head and smiled. He asked a question in what Deo guessed was English. Then a woman who had been sitting nearby got up and walked over French, at long last French, coming out of her mouth. Perhaps she could help, the woman said in French. Deo thought: “God. I’m still in your hands.” She arranged to sit next to him on the flight to New York and asked him lots of questions. Deo wanted to pay her back for helping him. So he tried to answer her questions. They talked most of the way to New York. After such long solitude (独处), it felt wonderful to talk.
When he reached Immigration the agent stared at Deo’s documents, then started asking questions in what had to be English. There was nothing to do except smile. The agent went off and came back with another man. He introduced himself to Deo in French. His name was Muhammad. He said he came from Senegal. Muhammad asked Deo the agents’ questions and also some questions of his own. For the agents, he asked Deo, “Where are you coming from?” When Deo said he had come from Burundi, Muhammad made a pained face and said to him in French, “How did you get out?”
There was no time even to attempt an answer. The agents were asking another question: Deo’s visa said he was here on business. What business?
Selling coffee beans, Deo told them through Muhammad. Just keep smiling, Deo told himself.
How much money did he have?
Two hundred dollars, Deo said with pride. The cash had been a gift from Jean. Exchanged for Burundian francs, it could have bought a lot of cows. But neither Muhammad nor the agents looked impressed.
Where was he staying?
Jean had told him he’d be asked this. A hotel, he said.
The agents laughed. A week in a hotel on two hundred dollars?
In 1994, airport security wasn’t what it soon would be. Muhammad said something in English to the agents. His words must have been the right ones, because after a few more questions, the agents shrugged at each other and let him through, into America.
He had no idea what he’d do next. After six months on the run, he was in the habit of not looking ahead. And what was there to fear? What could the man in the booth up ahead do to him? Whatever it might be, he’d already seen worse. God had taken care of him so far. And still was taking care of him, it seemed. As this serious-looking stranger, Muhammad, walked him out of Customs, he said that Deo could stay with him in New York City. But Deo would have to wait here for three hours. Muhammad worked at the airport as a baggage handler. He had to finish his shift. Could Deo wait three hours?
Only three hours? said Deo. Of course!

9 . In the atmosphere， carbon dioxide acts rather like a one-way mirror the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping.
According to a weather expert's prediction， the atmosphere wilbe3C warmer in the year 2050thanitis today， if man continues to burn fuels at the present rate.If this warming up took place， the icecaps in the poles would begin to melt thus raising sea level several meters and severely flooding coastal cities.Also， the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球) ， possibly resulting in an alteration of the earth's chief food-growing zones.
In the past， concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic， which maybe affected by only a few degrees of warming：in other words， by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.
Satellite pictures show that large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
However， most of the fuel is burnt in the northern hemisphere， where temperatures seem to be falling Scientists conclude，therefore，that up to now natural influences on the weather have exceeded those caused by man.The question is：Which natural cause has most effect on the weather?
One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and“cold”spots(that is， the relatively less hot spots) on the sun.As the sun rotates(旋转) ， every 27.5 days it presents hotter or“colder”faces to the earth， and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure， and consequently on wind circulation.The sun is also variable over along term：its heat output goes up and down in cycles， the latest trend being downward.
Scientists are now finding mutual relations between models of solar-weather interactions and the actual climate over many thousands of years， including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(惯性) of the earth's climate.If this is right，the warming effect of carbon dioxide might thus be serving as a useful counter-balance to the sun's diminishing(减少) heat.
1. Why is the fuel consumption greater in then or them hemisphere， but temperatures there seem to be falling?| A．Mainly because the levels of carbon dioxide are rising. |
| B．Possibly because the output of solar energy varies. |
| C．Because the inertia of the earth's climate take effect. |
| D．Possibly because the icecaps in the poles are melting |
| A．the climate of the world should be becoming cooler |
| B．the new Ice Age will be delayed by the greenhouse effect |
| C．the man-made warming effect helps to increase the solar effects |
| D．it will take thousands of years for the inertia of the earth's climate to take effect |
| A．the best way to overcome the cooling effect would be to burn more fuels |
| B．ice would soon cover the northern hemisphere |
| C．the increased levels of carbon dioxide would warm up the earth quickly |
| D．the greenhouse effect could work to the advantage of the earth |
| A．the greenhouse effect |
| B．the solar effects on the earth |
| C．the models of solar-weather interactions |
| D．the causes affecting weather |
10 . Like most robots, social robots use artificial intelligence to decide how to act on information received through cameras and other sensors. The ability to respond in ways that seem lifelike has been informed by research into such issues as how perceptions (知觉) form, what constitutes social and emotional intelligence, and how people can infer others’ thoughts and feelings. Advances in Al have enabled designers to translate such psychological and neuroscientific insights into algorithms that allow robots to recognize voices, feces and emotions; interpret speech and gestures; respond appropriately to complex verbal and nonverbal cues; make eye contact; speak conversationally; and adapt to people’s needs by learning from feedback, rewards and criticisms.
A 47-inch humanoid (类人物) called Pepper (from SoftBank Robotics) recognizes faces and basic human emotions and engages in conversations via a touch screen in its “chest,” About 15,000 Peppers worldwide perform such services as hotel check-ins, airport customer service, shopping assistance and fast-food checkout. Temi (from Temi USA) and Loomo (Segway Robotics) are the next generation of personal assistants—like Amazon Echo and Google Home but mobile, providing a new level of functionality. Loomo, for instance, is not only a companion but can also transform on command into a scooter (小型摩托车) for transport.
Social robots have particular appeal for assisting the world’s growing elderly population. The PARO Therapeutic Robot (developed by Japan’s National Institute of Advanced Industrial Science and Technology), which looks like a seal, soft and cute, is meant to stimulate and reduce stress for those with Alzheimer’s disease and other patients in care facilities: it responds to its name by moving its head, and it cries for petting. Mabu (Catalia Health) engages patients, particularly the elderly, as a wellness aide, reminding them to take walks and medication and to call family members. Social robots are also gaining popularity with consumers as toys. Early attempts to include social behavior in toys, such as Hasbro’s Baby Alive and Sony’s AIBO robotic dog, had limited success. But both are resurging (复活), and the most recent version of AIBO has advanced voice and gesture recognition, can be taught tricks and develops new behaviors based on previous interactions.
Worldwide sales of consumer robots reached an estimated $5.6 billion in 2018, and the market is expected to grow to $19 billion by the end of 2025, with more than 65 million robots sold a year. This trend may seem surprising given that multiple well-funded consumer robot companies, such as Jibo and Anki, have failed. But a wave of robots is lining up to take the place of old robots, including BUDDY (Blue Frog Robotics), a big-eyed mobile device that plays games in addition to acting as a personal assistant and providing home automation and security.
