21、Today’s artificial intelligence may not be that clever, but it just got much quicker in understanding. A learning program designed by three researchers can now recognize and draw handwritten characters after seeing them only a few times, just as a human can. And the program can do it so well that people can’t tell the difference.
The findings, published in the journal Science, represent a major step forward in developing more powerful computer programs that learn in the ways that humans do.
Although computers are excellent at storing and processing data, they’re less-than-stellar students. Your average 3-year-olds could pick up basic concepts faster than the most advanced program.
In short, “You can generalize,” said coauthor Joshua Tenenbaum. But there’s something else humans can do with just a little exposure—they can break an object down into its key parts and dream up something new. “To scientists like me who study the mind, the gap between machine-learning and human-learning capacities remains vast,” Tenenbaum said. “We want to close that gap, and that’s our long-term goal.”
Now, Tenenbaum and his colleagues have managed to build a different kind of machine learning algorithm ( 算 法 )—one that, like humans, can learn a simple concept from very few examples and can even apply it in new ways. The researchers tested the model on human handwriting, which can vary sharply from person to person, even when each produces the exact same character.
The scientists built an algorithm with an approach called Bayesian program learning, or BPL, a probability-based program. This algorithm is actually able to build concepts as it goes.
In a set of experiments, the scientists tested the program using many examples of 1,623 handwritten characters from 50 different writing systems from around the world. In a one-shot classification challenge, people were quite good at it, with an average error rate of 4.5 percent. But BPL, slightly edged them out, with a comparable error rate of 3.3 percent. The scientists also challenged the program and some human participants to draw new versions of various characters they presented. They then had human judges determine which ones were made by man and which were made by machine. As it turned out, the humans were barely as good as chance at figuring out which set of characters was machine-produced and which was created by humans.
The findings could be used to improve a variety of technologies in the near term, including for other symbol-based systems such as gestures, dance moves and spoken and signed language. But the research could also shed fresh light on how learning happens in young humans, the scientists pointed out.

22、 The first Europeans came to America in 1492 with Christopher Columbus. Since that time people have come to America from all over the world, from Europe, Africa, and Asia, and they have brought their music with them. This mixing of people and music has created American music.
Music is a very important part of our lives. Music is for dancing, drinking, eating, loving and thinking. Some songs remind us of our childhood or youth. Others remind of the people we love. Many important occasions, like weddings and funerals have special music. Every nation has a national song like the American 'The Star-Spangled Banner. ' In the U.S, high schools and colleges have school songs too.
Music is a part of the history of America. It expresses the problems and feelings of its people.
As the years pass, the music grows and changes.
Modern science has also changed music. Inventions like records, radios, movies, electric instruments, tape recorders, and videos have changed the way we play and listen to music. They have helped to make music an important form of international communication.
American music, from the earliest folk songs to modern 'pop', is known around the world. Music is one of America’s most important exports. It brings the people of the world together. Even when people cannot understand the same language, they can share the same music. Many people learn and practice English by singing songs, and understanding American music can help you understand American people. 'Put a dime (10 cents) in the juke box (自动点唱机), baby. ' Let's listen to the music!
【1】The article mainly tells us about____.
A.how American music developed
B.when American music developed

23、When Liam Pope-Lau fell into the ocean during a sailing lesson, he had no idea what he was in for. “I just remember how cold it was,” Liam recalls. “It really scared me and shook me up.” Thankfully, he was wearing a life jacket, but the water was freezing.
Liam’s scary experience inspired him to team up with his friend, Fraser Tuck, in his Grade 6 science class at the time. Together they came up with the idea of “LifeHeat” — a self-heating life jacket that could one day help someone in a similar situation. During the first phase, they concentrated on finding a chemical that creates heat upon contact with water. After a series of investigations, Liam and Fraser came across calcium chloride (氯化钙). It soon became LifeHeat’s primary chemical component, which allowed the life jacket to remain warm underwater.
Over the next two years, Fraser and Liam built 13 prototypes (模型) of LifeHeat. But instead of building multiple life jackets from scratch (从零开始), the two focused on creating an attachable pouch (荷包). When the pouch came in contact with water, it could heat the body’s core. For each prototype, Liam and Fraser experimented with different materials that could contain calcium chloride while still allowing its heat to escape. In the process, they experienced countless failures which, however, led them to be more creative.
The two have entered their many prototypes into several science competitions over the last two years. In November last year, Liam and Fraser won two awards at a big science fair. They are now taking the feedback they received from experts and applying it to their next prototype. Liam and Fraser anticipate turning their invention into a business.
As for future inventors, Fraser and Liam have advice for kids who want to create their own new technology. “Don’t be afraid to try it out because you never know where it could end up,” said Liam. “Go for it before someone else can steal your idea,” added Fraser with a laugh.
【1】What gives Liam the desire to invent the “LifeHeat”?
A.A science class.
B.An amusing experience.
C.A special life jacket.
D.A cold struggle in water.
【2】What do the Fraser and Liam focus on initially?
A.Finding a suitable chemical.
B.Building multiple life jackets.
C.Creating an attachable pouch.
D.Testing the prototypes of LifeHeat.
【3】What can we learn about the “LifeHeat”?
A.It has been put on the market.
B.It is invented through trial and error.
C.Two of its prototypes won awards at a science fair.
D.The attachable pouch is the most important part of it.
【4】Which of the following can best describe Fraser and Liam?
A.Humorous and ambitious.
B.Courageous and competitive.
C.Creative and determined.
D.Humble and intelligent.
24、26-year-old Anna Cherdantseva, from the city of Ufa in Russia, is a full-time employee of a furniture company, spending up to 10 hours every day trying out new sofas for comfort and safety.
Last month, Russian furniture giant M25 Group announced that it was taking application for a new position. Although all new products are tested in a specialized laboratory, management decided that in order to better meet the needs of consumers it needed some feedback(反馈) on real-life use of its sofas. In just a few days, M25 received over 5,000 job applications.
"We selected candidates in several stages," M25 Group spokesperson Anastasia Russkih said. "Initially we checked their CVs, and then we let them tell us why they wanted the job." Eventually, the furniture company shortlisted just 7 candidates, out of which Anna Cherdantseva, a 26-year-old marketing expert, proved to be the most suitable for the job. "It was a real fight for my dream job," Anna said after getting selected.

Anna Cherdantseva is at present on a three-month probation(试用期) at M25, but the company claims that as long as she proves to be up to the task, they plan on offering her a permanent position. The young woman will receive a monthly salary of 56,000 rubles($l,000) for the first three months. It's not so bad for sitting on the job.
