    Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.

Why is poker(扑克)so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an “information incomplete” game. Players have to guess opponents' hands from their actions—-tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

    Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

    Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

    Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

    After two hours of quite defensive play, from the computer at least, we called it a draw.

(1)、Why can't the computer beat humans at the poker game?

A、Because humans are cleverer than the computer B、Because humans practice playing the poker game every day C、Because the computer can't know the other players' cards completely D、Because the computer can't learn the regular rules of the poker game
(2)、What does the underlined word “vanquishes” in Paragraph 3 mean?

A、Leaves B、Defeats C、Cheats D、Serves
(3)、What do we know about the reinforcement learning of AI?

A、It solves problems correctly every time B、It is the same as the learning of humans C、It learns from the mistakes appearing in a task D、It is more developed than the studying ways of humans
(4)、What can be inferred from the text?

A、The new procedure of AI has some features of humans B、Computers are stronger than humans in every aspect C、Humans will beat computers at playing poker forever D、Scientists feel unhappy about the result of the poker game

    Speaking in public meetings is necessary for many students and employees. As well, it is a difficult task for them, especially for non-native speakers. A great many researchers have made efforts to help foreign language learners to improve the approaches.

    Charles LeBeau is a public speaking professor and consultant. Currently, he teaches at two universities and at the Toshiba International Training Center. He has also written books on the subject. English language learners around the world use his book Speaking of Speech.

    In Speaking of Speech Mr. LeBeau says a simple approach helps the learners. So, the professor divides public speaking into three parts: the physical message, the visual message, and the story message. He says, “The central thing to remember about public speaking or presentation is that it's a very complex communicative activity. For non-native speakers it's a really scary activity. So to make that more simplistic and easy for them, the approach that I've taken is to simplify and break it down. First if we look at presentation, what's going on? There are basically three messages that the presenter is giving the audience at the same time. There's what I call the physical message, namely body language. It's the way that my body, as a speaker, is talking to the audience. Then there's also the visual message. The visual messages are the slides that we now make and show the audience. The third message is the story message, which is the content of our presentation. The story message is the verbal message, what we say to the audience. The story message also includes how we organize our ideas to present to the audience.”

    He says the simple approach to breaking down the parts of public speaking has proved itself. He says learners improve quickly and do a good presentation after a few days of study.

    Teenagers like watching TV, but their weight problem is becoming more and more serious. Sports shoes that work out whether their owner has done enough exercise to assure time in front of the television have been designed in the UK.

    The shoes named Square Eves contain an electronic pressure sensor and a tiny computer chip to record how many steps the weather has taken in a day. A wireless transmitter (发射器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day's efforts.

    The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. We looked at current issues and childhood overweight really stood out,” she says. "And I wanted to deal with that with my design.”

    Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.

    Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.

    Existing pedometer (计步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”

    You may have heard of the American Dream, an ideal that has powered the hopes of Americans for generations.

    It began as a belief that the US was a land of opportunity, and that anyone could achieve success through hard work. The dream has referred to home ownership, a good job, retirement security or each generation doing better than the last for a long time.

    Yet today, this concept seems to have greatly changed. As Tune magazine pointed out, quite different from the older generation, many Millennials (the generation born after 1980) redefine the American Dream as “day-to-day control of your life”. They “prize job mobility, flexible schedules, any work that is more interesting than typing, and the ability to travel”, said the magazine.

    Home ownership, once the cornerstone of the American Dream, is becoming a smaller priority for this generation. Meanwhile, nearly 40% of them choose travel as part of their dream. And running their own business is a rising favorite, as nearly 26% of Millennials consider self-employment as part of their dream.

    So what has led to this huge change?

    Many point fingers at the poor economy. “Modern young Americans seem bound to face a world stamped by ever narrowing opportunity,” noted The Daily Beast.

    “The rate of 16-to-24-year-olds out of school and out of work is unusually high at 15%. Many college graduates have taken jobs that don't require a degree,” Time reported.

    The magazine worries that these difficulties may lead to a lost generation who are “unable to ever truly find their feet on the corporation's ladder”.

    Dan Kadlec, a reporter of Time, sees Millennials as resetting their expectations. “This situation is different for young adults today,” he wrote. “A true American dream has to feel attainable, and many Millennials are feeling they can only attain a day-to-day lifestyle that suits them.”

    Theater is one of the oldest and most important art forms in world culture, it is also one of the richest art forms. Many people work together to bring a play to life. There are playwrights, directors, set designers, costumers, lighting technicians, and, of course, actors. If the performance is a musical, the skills of a songwriter, a choreographer, and musicians are also required. The excitement of opening night can be felt by the people waiting to watch a performance and by the performers and workers backstage waiting for the curtain to go up. Live theater is thrilling because no one really knows how well the play will go until it is performed.

    The word theater comes from the Greek theatron, which means "a place for seeing." One concept from Greek theater that is still seen in some plays today is the "Greek Chorus". This consists of several actors or characters watching the action of the play(almost like the audience) and then commenting on what whey just saw with either reactions or dialogue.

Although most people think of the theater in terms of a play performed on the stage, theater has taken on a much broader meaning in the modern world. You may find yourself walking into a theater with no seats in the rows. Instead, you are seated among the set pieces, which makes you part of the setting. Sometimes theater may come to life on a street corner, or in a classroom. The excitement of theater is in its very nature—-it is an art form that changes as it is interpreted(诠释) in different ways by different people. That is probably why the works of the greatest playwright of all time, William Shakespeare, are still performed and enjoyed today, both in classic and new interpretations.
