3 . In a few decades, artificial intelligence (AI) will surpass many of the abilities that we believe make us special.
One of the most significant pieces of news from the US in early 2017 was the efforts of Google to make autonomous driving a reality. According to a report, Google’s self-driving cars clocked 1,023, 330 km, and required human intervention 124 times. That is one intervention about every 8,047 km of autonomous driving. But even more impressive is the progress in just a single year: human interventions fell from 0. 8 times per thousand miles to 0.2, a 400% improvement. With such progress, Google’s cars will easily surpass my own driving ability later this year.
Driving once seemed to be a very human skill. But we said that about chess, too. Then a computer beat the human world champion, repeatedly. The board game Go(围棋) took over from chess as a new test for human thinking in 2016, when a computer beat one of the world's leading professional Go players.
Perhaps, if we continue to improve information-processing machines, we’ll soon have helpful rational(理性的)assistants.
A.So we must aim to complement the rationality of the machine, rather than to compete with it. |
B.With computers conquering what used to be deeply human tasks, what will it mean in the future to be human? |
C.We must face our fears if we want to get the most out of technology and we must conquer those fears if we want to get the best out of humanity. |
D.This is a grand challenge for our age and it may require an “irrational” response. |
E.But most of all we need to keep the long-term perspective in mind: that even if computers will outsmart us, we can still be the most creative. |
F.Actually, it all comes down to a fairly simple question: What’s so special about us? |
G.Professor Stephen Hawking has warned that the creation of powerful artificial intelligence will be “either the best, or the worst thing, ever to happen to humanity”. |
Topic 1. Characters in literature are revealed by what they say and do and by what others say about them. Choose one of the following characters to analyze: Bruno, Shmuel, Gretel, Bruno’s father, Lieutenant Kotler.
Topic 2. Although Bruno feels that Shmuel is like his twin, the boys are different in many ways. Compare the two characters and write down their similarities as well as differences.
Topic 3. What do you think of the ending of the story (Bruno’s death)? What is the author trying to tell us through this ending?

5 . Mathew White, an environmental psychologist, is on a mission to give Mother Nature the respect he thinks she deserves when it comes to human health. For decades, scientists and health-care professionals have recognized that exposure to green spaces, such as public parks or forests, is linked with lower risks of all sorts of illnesses common in the world. Experimental work has demonstrated various physiological responses that occur when people spend time in natural environments: blood pressure drops, heart rate decreases, immune function improves, and the nervous system directs the body to rest and digest.
As humans increasingly populate urbanized areas, they are spending less and less time in natural environments. But before doctors can start advising their patients to head to the nearest park, there is an important outstanding question, says White: How much time in nature do you need to generate these apparent benefits? Most of the research that has linked health outcomes with exposure to the natural world didn’t use frequency or duration of park visits, but rather the amount of green space within a certain distance of a person’s home, White says. But “it’s not so much where you live; it’s whether you use it or not.”
So he collected data to estimate what dose(剂量) of nature was needed to show benefits to a person’s health. White’s group found the answer he was after: Spending at least two hours in nature per week was strongly correlated with self-reports of being in good health or having high wellbeing. “I was very surprised, to be honest,” says White, who had been expecting a much longer time. “We had no idea that such a clear threshold of time per week would emerge from the data.”
He was further surprised to learn that it didn’t seem to matter how many trips to a park people took, so long as they got in their two hours per week. It could be a long visit one day, a couple of hour-long trips, three visits of 40 minutes, or four half-hour excursions. He and his colleagues speculate that, if nature’s apparent health benefits are a result of being able to de-stress, then whatever pattern of green space exposure fits one’s schedule is probably the best way to achieve that goal.
Health-care recommendations for people to spend time in nature are probably years away, but the movement has begun. Several organizations around the world are working to promote awareness of nature’s contribution to health. Some researchers have used the term “a dose of nature” to evaluate the amount of exposure needed to gain benefits. “That was kind of the deliberate medicalization of the language around nature and health,” says White.

6 . The way Jason Momoa describes Hawaii’s beloved inactive volcano, Mauna Kea, makes you understand why it’s considered sacred(神圣的).
"It’s kind of the umbilical cord(脐带) to earth," the actor tells CNN. "You know, if you think about the Hawaiian islands, that’s the biggest mountain in the world, right? All the way up. So Mauna Kea is the most sacred. We call it the belly button, too. That’s like our birthplace. That’s how our islands were formed. So how can that not be sacred?"
He would know. Jason, a native of Hawaii, has had a near-constant presence there when he’s not working, fighting with local protestors to stop the construction of the Thirty Meter Telescope, or TMT, which would drill directly into the mountain and invade its precious water supply. So far, protestors have successfully blocked the only road crews seeking to go up the mountain in order to build the billion-dollar observatory.
"It started in 2015. What’s happening over there was just not right," Jason says. "And I went over there to meet with everyone to bring the point to the world." Jason joins the protests when he can. He cared so deeply about the preservation of the land that when he had spare time to lend his support, he was there. "You also have to remember, that’s our water source. So having an 18-story building built on top of the tallest mountain from the sea level on our water level is terrible."
The Game of Thrones star says he feels the movement is working and describing his part in it as a calling to do what he feels right in his soul. "There’s massive progress that’s bringing our people together," he says, adding, "I think there are a lot of problems in Hawaii. There are a lot of things that have happened in our history, a lot of injustice, and so we’re shining a light on it. People like myself or Dwayne Johnson, Bruno Mars are trying to spread the concern all around the world. For my soul I need to be there."

7 . Financial regulations in Britain have imposed a rather unusual rule on the bosses of big banks. Starting next year, any guaranteed bonus of top executives could be delayed 10 years if their banks are under investigation for wrongdoing. The main purpose of this “clawback” rule is to hold bankers responsible for harmful risk-taking and to restore public trust in financial institution. Yet officials also hope for a much larger benefit: more long-term decision-making not only by banks but also by all corporations, to build a stronger economy for future generations.
“Short-termism” or the desire for quick profits, has worsened in publicly traded companies, says the Bank of England’s top economist, Andrew Haldane. He quotes a giant of classical economies, Alfred Marshall, in describing this financial impatience as acting like “Children who pick the strawberries out of their pudding to eat them at once” rather than putting them aside to be eaten last.
The average time for holding a stock in both the United States and Britain, he notes, has dropped from seven years to seven months in recent decades. Transient(短期的) investors, who demand high quarterly profits from companies, can hold back a firm’s efforts to invest in long-term research or to build up customer loyalty. This has been called “quarterly capitalism”.
In addition, new digital technologies have allowed more rapid trading of equities( 股 票 ), quicker use of information, and thus shortens attention spans in financial markets. “There seems to be an advantage of short-term thinking at the expense of long-term investing,” said Commissioner Daniel Gallagher of the US Securities and Exchange Commission in speech this week.
In the US, the Sarbanes-Oxley Act of 2002 has pushed most public companies to delay performance bonuses for senior executives by about a year, slightly helping reduce “short-termism.” In its latest survey of CEO pay, The Wall Street Journal finds that “a substantial part” of executive pay is now tied to performance.
Much more could be done to encourage “long-termism,” such as changes in the tax code and quicker disclosure(披露) of stock acquisitions. In France, shareholders who hold onto a company investment for at least two years can sometimes earn more voting rights in a company.
Within companies, the right compensation design can provide motivation for executives to think beyond their own time at the company and on behalf of all shareholders. Britain’s new rule is a reminder to bankers that society has an interest in their performance, not just for the short term but for the long term.

It’s common knowledge that the woman in Leonardo da Vinci’s most famous painting seems to look back at observers, following them with her eyes no matter where they stand in the room. But this common knowledge turns out wrong.
A new study finds that the woman in the painting is actually looking out at an angle that’s 15. 4 degrees off to the observer’s right-well outside of the range that people normally believe when they think someone is looking right at them. In other words, said the study author, Horstmann, “She’s not looking at you. “ This is somewhat ironic, because the entire phenomenon of a person’s gaze (凝视) in a photograph or painting seeming to follow the viewer is called the “Mona Lisa effect” . That effect is absolutely real, Horstmann said. If a person is illustrated or photographed looking straight ahead, even people viewing the portrait from an angle will feel they are being looked at. As long as the angle of the person’s gaze is no more than about 5 degrees off to either side, the Mona Lisa effect occurs.
This is important for human interaction with on-screen characters. If you want someone off to the right side of a room to feel that a person on-screen is looking at him or her, you don’t cut the gaze of the character to that side-surprisingly, doing so would make an observer feel like the character isn’t looking at anyone in the room at all. Instead, you keep the gaze straight ahead.
Horstmann and his co-author were studying this effect for its application in the creation of artificial-intelligence avatars(虚拟头像) when Horstmann took a long look at the “Mona Lisa” and realized she wasn’t looking at him.
To make sure it wasn’t just him, the researchers asked 24 people to view images of the “Mona Lisa” on a computer screen. They set a ruler between the viewer and the screen and asked the participants to note which number on the ruler intersected(和……相交) Mona Lisa’s gaze. To calculate the angle of Mona Lisa’s gaze as she looked at the viewer, they moved the ruler farther from or closer to the screen during the study. Consistently, the researchers found, participants judged that the woman in the “Mona Lisa” portrait was not looking straight at them, but slightly off to their right.
So why do people repeat the belief that her eyes seem to follow the viewer? Horstmann isn’t sure. It’s possible, he said, that people have the desire to be looked at, so they think the woman is looking straight at them. Or maybe the people who first coined the term “Mona Lisa effect” just thought it was a cool name.
