WASHINGTON – It’s a great achievement that inspires notions of robots with consciousness and independent minds.
When people or animals get hurt, they can usually compensate for minor injuries and keep limping along, but for robots, even slight damage can make them stumble and fall. However, a recently made robot has demonstrated a novel ability: it can heal its own damage.
The new robot, which looks like a splay – legged, four – footed starfish can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unfamiliar places. “There is a need for planetary robotic rovers to be able to fix things on their own,” says Josh Bongard, a professor in the University of Vermont, who is one of the device’s creator. “Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program, but the new robot works differently. First, sensors in its four legs observe the robot’s movements and signals to its built – in computer. From the formation it collects, the robot creates its own programs that allow it to adapt to different situations. For example, when the researchers shortened one of the robot’s legs, the smart machine simply adjusted its way of walking – it used three legs instead of four.
The researchers are looking for other places to put the resilient robot to work. One pellicle spot is the ocean floor. That dark and dangerous undersea terrain might be a good choice for a robot the scientists call the Starfish. “We never officially named the robot, but we usually refer to it as the Starfish, even though a real starfish has five rather than four legs,” says Bongard. “Also, a real starfish is much better than our robot at recovering from injury, because it can actually grow its legs again.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.
46.The newly designed robot distinguishes itself from the former ones because it___________
A.can communicate with people on the earth about their problems
B.works according to a certain computer program
C.can find its problems and solve them automatically
D.can explore unfamiliar places
47.An example is given in the fourth paragraph in order to explain that the robot ___________
A.is used to create new programs
B.has typical robot functions
C.has sensors to observe its movements
D.can gather information and adapt to new conditions
48.The underlined word “resilient” in the last paragraph means the robot is ___________.
A.creative B.newly made C.able to recover D.informative
49.Which of the following is TURE about the robot “Starfish”?
A.It was spoken highly of by people for its special ability?
B.It will stumble and fall if damaged.
C.It can grow its legs again once they are broken.
D.It has started to work on the ocean floor.
50.What might be the best title of the passage?
A.How does the Starfish Robot work
B.Do – It – Yourself Robot Repair
C.Robots Designed to Work On Other Planets
D.New Robot Helping Us In Many Ways

LOS ANGELES-British singing sensation Susan Boyle’s first album quickly climbed to No. 1 on U.S. album charts on Wednesday with sales of 701,000 copies, beating new releases by Adam Lambert and Rihanna and becoming the best-selling debut(首次演出) of 2009. Boyle, 48, a frumpy Scottish singer, who became an international YouTube phenomenon after appearing on TV show “Britain’s Got Talent”, also topped the British album charts earlier this week.
Her “I Dreamed a Dream” release through Sony Music Entertainment, marked the best U.S. opening of a female artist"s debut album since Nielsen SoundScan began tracking sales in 1991, Billboard.com said. It was also the fastest selling album in Britain this year and has topped the charts in Australia and Ireland.
Billboard said only one album in SoundScan’s tracking history had seen a bigger opening week than Boyle. U.S. rapper Snoop Dogg’s album “Doggystyle” sold 803,000 copies in its first week in 1993—before traditional album sales began tumbling(falling rapidly) in the face of piracy(盗版) and a shift to digital sales.
Although Boyle finally failed to win “Britain’s Got Talent”, her April trial hearing for the show has been viewed more than 300 million times on the Internet.
In a good week for stars of TV talent shows, “American Idol” runner-up Adam Lambert’s debut album “For Your Entertainment”, also released through Sony, debuted at No.3 on the Billboard 200 with 198,000 copies sold. Lambert’s strong showing followed headline news coverage of his bad televised live performance at the American Music Awards 10 days ago in which he aroused oral sex with a dancer and kissed a male keyboard player.
R&B singer Rihanna’s “Rated R”, her first studio album since being attacked by her then-boyfriend Chris Brown in February, bowed in at No.4 with 181,000 copies—the best sales week in the 21-year-old singer’s career.
Italian singer Andrea Bocelli held onto the No.2 spot for a third week with his “My Christmas” album with 218,000 new copies sold during the week, SoundScan said.
60. According to the passage, what albums were released through Sony Music Entertainment?
A. Doggystyle and I Dreamed a Dream.
B. For Your Entertainment and I Dreamed a Dream.
C. Rated R and Doggystyle.
D. My Christmas and For Your Entertainment.
61. What do you learn from the passage?
A. Doggystyle marked the biggest opening week in SoundScan’s tracking history.
B. I Dreamed a Dream was the fastest selling album in English-speaking countries.
C. Upon its release, Boyle’s first album ranked first on album charts on Wednesday.
D. Boyle became world-famous after she won Britain’s Got Talent.
62. Who may perform crazily and leave audience a bad impression?
A. Susan Boyle. B. Andrea Bocelli. C. Rihanna. D. Adam Lambert.
63. From the passage we can conclude _______.
A. The albums could have sold better if it had not been for piracy and a shift to digital sales
B. Boyle became world-famous because she was a female artist.
C. Being attacked by her then-boyfriend might decrease the sales of Rihanna’s Rated R.
D. Andrea Bocelli’s album My Christmas only kept the No. 2 spot for two weeks.
The practice of using different pens to sign important legislation(法规)dates at least as far back as Franklin Roosevelt. The reason is fairly simple. The pen used to sign historic legislation itself becomes a historical artifact. The more pens a President uses, the more thank-you gifts he can offer to those who helped create that piece of history. The White House often give pens to supporters of the newly signed legislation. When Lyndon Johnson signed the Civil Rights Act in 1964, he reportedly used more than 75 pens and gave one of the first ones to Martin Luther King Jr. And in 1996, President Clinton gave the four pens he used to sign the Line-Item Veto bill to those most likely to appreciate the bill"s consequence.
Once they"re given away, some pens end up in museums; others are displayed proudly in recipients"(接受者) offices or homes. But they sometimes appear again, like in the 2008 presidential campaign(竞选活动), when John Macain promised to use the same pen given to him by President Reagan to cut pork from the federal budget.
Not every President goes for the multipen signature, however. President George W. Bush preferred signing bills with only one pen and then offering several unused "gift" pens as souvenirs.

Gates and Allen contacted Dr Roberts after seeing the machine on the front cover of a magazine and offered to write software for it. The program was known as Altair-Basic, the foundation of Microsoft"s business. "Ed was willing to take a chance on us - two young guys interested in computers , and we have always been thankful to him," the Microsoft founders said in a statement.
Apple co-founder Steve Wozniak told technology website CNET that Dr Roberts had taken " a critically important step that led to everything we have today".
Dr Roberts was the founder of Micro Instrumentation and Telemetry Systems (MITS), originally set up to sell electronics parts to model rocket hobbyists. The company went on to sell electronic calculator parts, but was soon overshadowed by bigger firms.
In the mid-1970"s, with the firm struggling with debt, Dr Roberts began to develop a computer kit(配套零件) for hobbyists. The result was the Altair 8800. The $395 kit (around £1,000 today) was featured on the cover of Popular Electronics in 1975, resulting in a flood of orders.
Amongst those interested in the machine were Paul Allen and Bill Gates. The pair contacted Dr Roberts, offering to write software that would help people program the machine. The pair finally moved to Albuquerque - the home of MITS - where they founded Micro-Soft, to develop their software.
Dr Roberts sold his company in 1977. He died in hospital on 1 April after a long period of pneumonia.(肺炎)
小题1:Why did Dr Roberts probably decide to sell his company?
A.Because he was in heavy debt in the mid-1980"s . |
B.Because he wanted to take a chance on Gates and Allen. |
C.Because he wanted to develop a computer kit for hobbyists. |
D.Because he had difficulty competing with big companies. |

Nearly ten years ago, I was told that I had a brain tumor (瘤), and this experience changed my attitude about adventure forever.I thought that I was going to die and that all my adventures were over.I did not have a brain tumor, it turned out, but rather multiple sclerosis (多发性硬化症), which meant that, although they were not over, the nature of my adventures could have to change.
Each morning that I wake up is a fresh event, something that I might not have had.Each gesture that I make carries the weight of uncertainty and demands significant attention: buttoning my shirt, changing a light bulb, walking down stairs.I might not be able to do it this time.If I could not delight in them, they would likely drown me in anger and in self-pity.
I admire the grand adventures of others.I read about them with interest.With Peter Matthiessen I have hiked across the Himalayas to the Crystal Mountain.I have walked with Annie Dillard up, down, into, and across Tinker Creek in all seasons.David Bain has gone with me along 110 miles of Philippine coast, and Ed Abbey has rowed me down the Colorado River.I enjoy the adventures of these courageous figures, who can strike out on difficult trips – 2 miles, 250 miles, 3000 miles – ready to bear cold and tiredness, indeed not just to bear but to celebrate.
But as for me, I can no longer walk very far from the armchair in which I read.Some days I don’t even make it to the backyard.And yet I’m unwilling to give up the adventurous life, the difficulty of it, even the pain, the anxiety and fear, and the sudden brief lift of spirit that makes a hard journey more attractive.
I refine adventure, make it smaller and smaller.And now, whether I am moving on my hands and knees across the dining room to help my cat, lying wide-eyed in the dark battling another period of sadness, gathering flowers from the garden, meeting a friend for lunch, I am always having the adventures that are mine to have.
