AlphaZero--an Updated Model of AI

    Soon after Garry Kasparov, the former world chess champion, lost his rematch against IBM's Deep Blue in 1997, the short window of human-machine chess competition slammed shut forever. Unlike humans, machines keep getting faster, and today a smartphone chess app can be stronger than Deep Blue. However, as people see with the new AlphaZero system, machine dominance has not ended the historical role of chess as a laboratory of cognition.

    Much as airplanes don't flap their wings like birds, machines don't produce chess moves like humans do. Based on a generic algorithm (算法), AlphaZero incorporates deep learning and other AI techniques like Monte Carlo tree search to play against itself to develop its own chess knowledge. Unlike the traditional program Stockfish, which employs many preset evaluation functions as well as opening and endgame moves, AlphaZero starts out knowing only the rules of chess, with no preset human strategies. In a few hours, it plays more games against itself than have been recorded in human chess history. It teaches itself the best way to play, reevaluating the relative values of the pieces. It quickly becomes strong enough to win 28, draw 72, and lose none in a victory over Stockfish. Since AlphaZero can program itself, this superior understanding allows it to outclass the world's top traditional program despite calculating far fewer positions per second. It's the typical example of the cliché, "work smarter, not harder".

    AlphaZero shows that machines can be the experts, not merely expert tools. Explainability is still an issue—it's not going to put chess coaches out of business just yet. But the knowledge it produces is information humans can learn from. AlphaZero is surpassing humans in a profound and useful way, and researchers are working on transferring the knowledge acquired from AlphaZero to other fields.

    Machine learning systems aren't perfect. Even though great progresses have been achieved, AI algorithms are still struggling on open problems such as computer vision, natural language understanding... There will be cases where an AI will fail to detect exceptions to its rules. Therefore, as Kasparov writes, "We must work together to combine our strengths. I know better than most people what it's like to compete against a machine. Instead of raging against them, it's better if we're all on the same side."

(1)、Questions⑴①-⑴⑤: Judge if the following statements agree with the information given in the passage.

举一反三

                                                                          Section A (10 marks)

          Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.

                          Not all print dictionaries are the same, as you will notice when you select one. To make a wise selection, you should know how to distinguish 

among three kinds of print dictionaries: pocket, desk, and unabridged. You should also know the copyright date of your dictionary, and

 check is special features.

          A pocket dictionary is small. Generally, it contains no more than 75000 entries, making it hardly to carry to class and efficient to use. 

However, a pocket dictionary doesn't contain enough entries to be adequate for college reference homework. In addition, the information 

about each word in a pocket dictionary is generally limited. A desk dictionary is medium sized, generally containing over 100,000 entries

 as well as extra features. For college work, you should own a current desk dictionary. An unabridged dictionary is a complete dictionary. 

Abridged dictionaries, such as pocket and desk dictionaries, are shortened. Because unabridged dictionaries contain nearly all English words,

 they are large and heavy. They are often used by schools and libraries.

           If the copyright date of your current dictionary shows that it was published five or more years ago, consider investing in a more recent 

edition. English is a dynamic language that admits new words and recognizes changes in meaning, spelling, and usage of familiar words.

 This is reflected in an up-to-date dictionary.

         In selecting a dictionary, check the features it offers besides vocabulary definitions. Many editions contain signs, symbols and foreign words.

 Some also contain CD-ROMs and access to special online features.

Just as team members today have assigned doing roles, there should also be thinking roles. By knowing how other members of your learn and organization think—and by others knowing how you think—everyone can be more productive. So how should you evaluate how you and your team think? After a lot of trial-and-error, we developed a three-step method that delivers practical and meaningful results.

    Focus. Do you tend to pay the most attention to ideas, process, action, or relationships? For example, in the morning do you think about the problems you need to solve, the plans you need to make, the actions you need to take, or the people you need to see? This isn't about picking one to the exclusion(排除)of the other. It's about where your focus naturally lands.

    Orientation(方向). A good way to identify your orientation is thinking about what tends to bother you in meetings. Are you more likely to complain about getting dragged into the weeds or about things being too general and not specific enough? These dimensions are complementary(补充的)to personality, skills, and traditional roles.

Combination. By combing these two dimensions you can know about the thinking style at work in whatever context or setting you chose. When you know your thinking style, you know what naturally energizes you, why certain type of problems are challenging or boring, and what you can do to improve in areas that are important to reaching your goals. Once you know your style, it helps to share it with others, and have others share theirs with you. In this way, your thinking style becomes a useful tool—a kind of social currency—for the team. Imaging you put together a team to work on a new initiative(行动). Wouldn't you like to know who is energized by big-picture strategy discussions and who finds them frustrating? Who likes to work on the details of the execution? And who is energized by managing the team dynamics?

    The landscape of business is changing rapidly, and we have to find new and better ways to connect and communicate. We all want to work better together, the challenge is actually making it happen. Understanding collaboration(合作)through the way of thinking rather than doing is a practical and powerful step forward.

What kind of Thinker Are You?

Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

Sustainable Cities Need More Than Parks, Cafes and a Riverwalk

    There are many standards that aim to rank how green cities are. But what does it actually mean for a city to be green or sustainable?

    We've written about what we call the "parks, cafes and a riverwalk" model of sustainability, which focuses on providing new green spaces, mainly for high-income people. This vision of shiny residential towers and waterfront parks has become a widely-shared conception of what green cities should look like. {#blank#}1{#/blank#}

    Gentrification(住宅高档化) has become a catch-all term used to describe neighborhood change, and is often misunderstood as the only path to neighborhood improvement. In fact, its defining feature is displacement. Typically, people who move into these changing neighborhoods are wealthier and more educated than residents who are displaced.

    A recent flood of new research has focused on the displacement effects of environmental cleanup and green space initiatives. {#blank#}2{#/blank#}

    Land for new development and resources to fund extensive cleanup of poisonous sites are scarce in many cities. {#blank#}3{#/blank#} And in neighborhoods where gentrification has already begun, a new park or farmers market can worsen the problem by making the area even more attractive to potential high-income people and pricing out long-term residents. In some cases, developers even create temporary community gardens or farmers markets or promise more green space than they eventually deliver, in order to market a neighborhood to buyers looking for green pleasantness.

    {#blank#}4{#/blank#} It makes deindustrialization seem both inevitable and desirable, often by quite literally replacing industry with more natural-looking landscapes. When these neighborhoods are finally cleaned up, after years of activism by longtime residents, those advocates often are unable to stay and enjoy the benefits of their efforts.

A. This phenomenon is often missing from development projects promoted as green or sustainable.

B. This phenomenon has variously been called environmental, eco-or green gentrification.

C. Greening and environmental cleanup do not automatically or necessarily lead to gentrification.

D. This creates pressure to rezone industrial land for residential towers or profitable commercial space, in exchange for developer-funded cleanup.

E. But it can drive up real estate prices and displace low- and middle-income residents.

F. Environmental gentrification naturalizes the disappearance of manufacturing and the working class.

    I have some gray hairs. Do l dare to count them? Just the fact that I have enough to count scares me, and turns getting old into a reality. I'm certainly getting older. We all are. But why does it have to happen so quickly?

    We just celebrated my birthday. I say "celebrated" because we had cake and ice cream. For my kids, any excuse for ice cream and cake is a celebration. I'm not sure if to me it was a thing to celebrate, though. I like the special attention that birthday bring, but I don't wait for them 364 days of the year like my children do. For them, another number means more privileges and more things that they get to do. For an adult, another number means fewer things. that you can do, like "I can't run as fast as I used to…etc. "

    I went with my children to the old-age home near my apartment building. We walked inside the door. The contrast between my preschoolers full of energy and the old women siting in the wheelchair by the door made me lost in thought. Not so long ago, I was a bouncing preschool like my children. Not so long ago, there women were the mothers of small children. Fifty years ago, they were me, and in fifty years, I could be them. The visit, like my birthday, served as a reality check. "Life is so short and it goes by so quickly. Enjoy the moment that you are in, because you will never get it back, "I told myself.

    This is also what I want to leave behind to my children. I decide to try to start just by not complaining. In any difficult situation, I will try to find the good things about it, no matter how small the good things might be.
