Cathy is a tetraplegic. She has not been able to move her arms, legs or speak since suffering a stroke(中风)nearly fifteen years ago. Recently, she learned how to control a robotic arm using her thoughts. She now can use brain activity to serve herself a drink.
The American woman is one of two people who took part in a research project known as BrainGate2. The researchers have spent years studying how to help people who are disabled regain movement in their arms and legs.
John Donoghue is a neuroscientist with Brown University and also was part of the project. He said, “People like Cathy have their brain disconnected from their body. So they are not able to go out and do everyday things that you and I can do, like reach for a glass of water or scratch your nose. Our idea is to avoid that damaged nervous system and go directly from the brain to the outside world, so the brain signals can, not control muscles, but control machines or devices like a computer or a robotic arm.”
The two disabled people had small sensors connected to the part of the brain that controls movement. The devices measured brain activity and sent that information to a computer. The computer has special software that turns the information into digital commands for operating other devices. The researchers used a highly developed robotic arm to recreate human actions.
The BrainGate team had its first success in 2006. A tetraplegic stabbing victim was able to use the brain—computer system to control a computer mouse. John says the latest development using robotic arms is a major victory.
A video of the latest experiment shows Cathy using the robotic arm to pick up a cup of coffee. She guides the cup toward her mouth, moves it forward and drinks through a straw.
Lead researcher Leigh Hochberg said the first time she did it was a magic moment.
The research team carried out almost 200 tests with two different robotic arms, which were able to pick up their target objects 43% to 66%of the time.
The researchers are calling the information very promising. But they say it will take years to fully develop the technology for everyday use.

Years ago, the American writer Kurt Vonnegut often said there was one story that would always make a million dollars: Cinderella.
In Hollywood and in today’s economy, it is more like $70 million and that is just a start. “Cinderella” made that amount in ticket sales when it opened last weekend. But the merchandising deals linked to the movie are also hugely valuable.
So the artistic success of the film is open to debate. What is clear, however, is the movie’s business success. It is a hit in the theaters but it is also a hit in retail (零售). And Disney widened its usual market for “Cinderella” products.
There are products connected to the Disney film targeted not only at little girls, but women, too. For example, the famous shoe designer Jimmy Choo partnered with Disney to create a version of Cinderella’s “glass slippers” or shoes. You can buy them for about $5,000. At that price, you would not want to lose one at the ball, even if that is the way you get your prince. Several other shoemakers also accepted Disney deals to design versions of the famous footwear.
The makeup company MAC quickly sold all its products with official links to “Cinderella.” But lucky buyers were soon selling the products on the online marketplace eBay for many times the original price.
HSN is a popular television and online retailer (零售商) of jewelry, clothing and objects for the home. The marketer is now an exclusive seller of “Cinderella” products.
So, is there anything left for the children, those people we think of as the traditional audience for the age-old fairy tale? Yes, you can find toys and other children’s products at the American retailer JC Penney. Of course, you can also visit a Disney store.
Disney also produced an animated version of “Cinderella.” It came out in 1950 and is considered a classic. Which do you think the Disney company does better: live action (实景真人) or animated films? Post your thoughts in the comments section.
1.Products connected to the film “Cinderella” are generally aimed at ________.
A. toy retailers B. shoe designers
C. female consumers D. make-up producers
2.The film “Cinderella” is also a hit in retail because ________.
A. it has always been warmly welcomed by successful businessmen
B. huge profits were made in the sales of various “Cinderella” products
C. box-office profit is much larger than the derivatives (衍生产品) of the film
D. Disney produced both a live action and an animated version of the film
3.What could be the best title for this passage?
A. “Cinderella” Is a Big Hit in the Theaters.
B. Two Different Versions of “Cinderella”.
C. Debates on the Artistic Success of “Cinderella”.
D. “Cinderella” Is More than Just a Movie for Kids.

The US plans to extend its endangered species protection to lions in Africa. US Fish and Wildlife Service (FWS) will classify lions in southern and eastern Africa as threatened. The move will place tighter restrictions on the import of lion “trophies(纪念品)”, such as paws or heads.
While the US cannot regulate hunting in other countries the move is significant because around half of all lion hunting in Africa is conducted by Americans. According to FWS data, more than 5, 600 lions have been killed and imported by American hunters over the past decade.
Under the new FWS rules, bringing lion parts to the US will be banned(禁止) in most circumstances if the animal is from a country where lions are endangered. Hunters will have to show the trophies were “legally obtained” from countries that have a scientifically sound management program that benefits the subspecies in the wild.
This regulation is expected to place a far greater burden of proof upon hunters who claim that the money from lion hunting has been used to help communities in Africa and the overall conservation of lions. The persistent downward trend in lion numbers, due to habitat loss and hunting by locals and foreign tourists, suggests there has been little conservation(保护) benefit from organized hunts.
An international study, published in September, found African lion numbers have decreased by half since 1993, with a further 50% decline expected over the next 20 years for populations in west, central and east Africa.
“The lion is one of the planet’s most beloved species and an irreplaceable part of our shared global heritage,” said Dan Ashe, director of the FWS. “If we want to ensure that healthy lion populations continue to wander around the African savannas(大草原) and forests of India, it’s up to all of us—not just the people of Africa and India--to take action.”
1.Why is the move of US significant?
A. The lions have been killed and imported by American hunters.
B. That is due to habitat loss and hunting by locals and foreign tourists.
C. Around half of all lion hunting in Africa is conducted by Americans.
D. The money from lion hunting has been used to help communities in Africa .
2.Where do most of the lion hunters come from?
A. Southern Africa. B. America.
C. Eastern Africa. D. India.
3.What may be the result of the move?
A. The import of lion parts will be strictly limited.
B. Lion-hunting will be illegal all over the world.
C. communities in Africa will benefit a lot.
D. Lion parts will never be legally obtained.
4.What does Dan Ashe really want to tell us in the last paragraph?
A. Almost everybody loves lions.
B. It’s everyone’s duty to protect lions.
C. Lion populations will increase rapidly.
D. Measures must be taken to keep lions fit.

Have you ever made contact with the creative spirit, that certain something hard to describe, but full of good—and sometimes great—ideas? It is more than an occasional great thought. When we feel the moving of the creative spirit, it brings to life a style of being: a lifetime filled with the desire to invent, to explore new ways of doing things, and to turn dreams into reality.
That flash of inspiration is the final moment of a process marked by unique stages—the basic steps in creative problem-solving. The first stage is preparation, when you look for any information that might be important. It's when you let your imagination run free.
But one barrier(障碍) is the inside voice of judgment that locks up our creative spirit within the limits of what we think acceptable. It's the voice that whispers to you, "They'll think I'm foolish," or "That will never work." But we can learn to recognize this voice of judgment and have the courage to discount its unhelpful advice.
Once you have thought about all the relevant(相关的) pieces and pushed your mind to the limits, you can let the problem remain and take in all you have gathered. It's a stage when much of what goes on occurs outside your focused awareness. As the saying goes, "You sleep on it."
We are more open to creative thoughts from the unknowing mind when we are not really thinking of anything. That is why daydreams are so useful in the search for creativity. Anytime you can just daydream and relax is useful in the creative process: a shower, long drives, a quiet walk, etc.
With luck, daydreaming will lead to a light turning on above your head, when all of a sudden the answer will come to you as if from nowhere. This is the popular stage—the one that usually gets all the glory and attention, the moment that people sweat and long for, the feeling "This is it!" But the thought alone is still not a creative act. The final stage is translation, when you take your creative thought and transform it into action; it becomes useful to you and others.
1.In Paragraph 1, “the moving of the creative spirit” probably means ________.
A. preparation B. exploration
C. problem-solving D. inspiration
2.According to the article, what keeps us from creativity?
A. Having less information to form a good idea.
B. Relying on others during the creative process.
C. Caring about other people’s opinions about us.
D. Thinking about too many ideas at the same time.
3.What can we learn from the fifth paragraph?
A. The unknowing mind is very difficult for us to understand.
B. Creativity arrives when we aren’t focused on anything.
C. Daydreaming is useless and has nothing to do with creativity.
D. Showers, long drives and quiet walk are good for our bodies.
4.When does creativity become useful to us and others?
A. When thought is turned into action.
B. When people understand our ideas.
C. When the popular stage is reached.
D. When we think “This is it!”.
5.Which of the following would the author probably support?
A. The creative spirit means an occasional great thought.
B. Others’ voice of judgment allows us to ignore barriers.
C. Creative problem-solving calls for barrier-free imagination.
D. Daydreaming is sure to bring a sudden answer to a problem.
