A team of researchers recently created a robot that can repair itself. The newly designed machine can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unexpected damage, it may be especially useful in exploring unfamiliar places. “There is a need for planetary robotic rovers(流浪者) to be able to fix things on their own,” says Josh Bongard, one of the device’s creators. “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 information 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(迅速恢复) robot to work. One possible spot is the ocean floor. That dark and dangerous undersea terrain(地带) 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 regrow its legs.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.

A. can communicate with people on the earth about their problems
B. works according to a certain computer program
C. can find problems itself and get used to the new environment
D. can explore unfamiliar places
2. An example is given in the second paragraph in order to explain that the new robot ___________.
A. is used to create new programs B. has typical robot functions
C. has sensors to observe its movements D. can adapt to new conditions
3. 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
4. Which of the following is True about the Starfish?
A. It has more than four legs. B. It hasn’t been officially named.
C. It can regrow its legs quickly. D. It has started to work on the ocean floor.

WASHINGTON Laura Straub is a very worried woman. Her job is to find families for French teenagers who expect to live with American families in the summer.
It’s not easy, even desperate.
“We have many children left to place: 40 out of 75,” said Straub, who works for a Paris based foreign exchange programme called LEC.
When exchange programmes started 50 years ago, more families were willing to help others. For one thing, more mothers stayed home.
But now, increasing numbers of women work outside the home. Exchange student programmes have struggled in recent years to sign up host families for the 30,000 teenagers who come from abroad every year to have some courses for one year in the United States. as well as the thousands more who take part in summer programmes.
School systems in many parts of the US, unhappy about accepting non taxpaying students, have also strictly limited the number of exchange students they accept. At the same time, the idea of hosting foreign students is becoming less exotic (异国情调的).
In searching for host families, who usually receive no pay, exchange programmes are increasingly broadening their requests to include everyone from young couples to the retired.
“We are open to many different types of families.” said Vickie Weiner, eastern regional director for ASSE, a 25-year-old programme that sends about 30,000 teenagers on one-year exchange programmes worldwide.
For elderly people, exchange students “keep us young——they really do,” said Jean Foster, who is hosting 16-year-old Nina Ports from Denmark.
1.Foreign teenagers come to American families with the purpose of _____.
A. finding their parents in America B. finding good jobs in America
C. learning the culture of America D. enjoying the life of America
2.In the past, Straub’s job was easy, because American families _____.
A. needed more money to live B. had fewer children to support
C. had spare rooms to rent D. were not as busy as now
3.To deal with the problem in recent years, Straub and her workmates have to _____.
A. ask different kinds of families for help B. limit the number of the exchange students
C. borrow much money to pay for the costs D. force some families to accept students
4.From the last paragraph we can conclude that _____.
A. exchange students are welcome in America
B. exchange students must pay much money to the host families
C. American students don’t want to join the exchange programmes
D. old Americans can benefit from hosting exchange students

第三部分阅读理解（共两节，满分40分）
第一节（共15小题，每小题2分，满分30分）
阅读下列短文，从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。
Just call Apolo Anton Ohno the most decorated sportsman in the history of the Winter Olympics. The speed skater glided into the history books after the 2010 Olympics, winning a record-breaking eighth Olympic medal after completing the men’s 5,000-meter relay.
Apolo Anton Ohno, born on May 22, 1982, is an American short track speed skating competitor and an eight-time medalist (two golds, two silvers, four bronzes) in the Winter Olympics. He is one of the only four Americans who have won three medals in a single Winter Olympic Games. He started skating at age 12, and in two years became the best short track skater in the United States. In December1999, he became the youngest skater to win a World Cup event title.
“It feels amazing, especially in a sport as volatile as short track speed skating,” he remarked after his historic win. “This is my third Olympic Games and there is no other athlete here who has gone to three Olympic Games and won a medal every time. I wanted to leave my heart and soul on the ice and I did. I don’t look back at past medals, but I look back at the struggles. I live my life with the philosophy that anything’s possible but I had no idea I’d have this much success.”
Ohno’s third Olympics might have been his last. He is considering retirement, although US national coach Jimmy Jang is hoping to convince his longtime friend to compete four years from now in Sochi, a Russian city where the next Winter Olympics is going to be held.
“I never say ‘never’,” Ohno said. “I need a break from this sport that’s been very good to me.”
After the relay, Ohno skated over to congratulate the Canadians and shook hands with his South Korean competitors. One of them said: “We have some good memories and we also have some bad memories of Ohno. I will be sorry to see him leave the world of short track when he does.”

31^st October —— A team of British explorers has announced they are going to the North Pole to measure the ice cap’s thickness. The exploration will take ground-based readings (仪表的读数) of an ice formation which most scientists agree is shrinking at an alarming rate.
Explorer Pen Hadow’s three-member team will pull a sled-fixed radar device, which measures ice density every eight centimeters, 2,000 kilometers across the Arctic and will produce millions of readings.
They will leave in February, 2008 and will face temperatures of -50℃ on a journey that will take up to 120 days. They have been testing their equipment in Britain and Canada.
Hadow is excited about the prospects (前景), “For the first time we will be able to transmit video images — webcam film of the expedition — as it unfolds so people can track us, and the whole idea is to engage as many people as we can in what we’re doing.”
New fallen snow on top of the ice makes ground-based measurements more accurate than satellite data.
“It has been in the planning stage for a while,” said Hadow. “We spent the last two years developing impulse radar (冲击雷达), which normally is about 100 kilograms and hangs under an aircraft and so on. We’ve managed to get it down to about 4 kilograms. It’s the size of a briefcase and we are dragging it behind the sled as we go.”
　　　　The ice cap shrank enough in 2007 so that a pathway through the cap known as the Northwest Passage opened up during the melting of the Arctic summer.
Cambridge University’s Joao Rodrigues explains, “Thickness of the ice cap will determine how much solar radiation will be reflected and the heat exchange between the ocean and the atmosphere and it is thus a vital component (成分) of climate models.”
If warming trends continue, some experts predict that the Arctic Ocean could be ice-free during the summer within a few decades.

Sometime in the next century, the familiar early-newspaper on the front porch (门廊) will disappear. And instead of reading your newspaper, it will read to you. You’ll get up and turn on the computer newspaper just like switching on the TV. An electronic voice will distribute stories about the latest events, guided by a program that selects the type of news you want. You’ll even get to choose the kind of voice you want to hear. Want more information on this brief story? A simple touch makes the entire text appear. Save it in your own personal computer if you like. These are among the predictions from communication experts working on the newspapers of the future. Pictured as part of broader home-based media and entertainment systems, computer newspapers will unite print and broadcast reporting, and offer news and analysis with video images of news events.
Most of the technology is available now, but convincing more people that they don’t need to read a newspaper is the next step. But resistance to computer newspapers may be stronger from within journalism. Since it is such a cultural change, it may be that the present generation of journalists and publishers will have to die off before the next generation realizes that the newspaper industry is no longer a newspaper industry. Technology is making the end of traditional newspapers unavoidable.
Despite technological advances, it could take decades to replace newsprint with computer screens. It might take 30 to 40 years to complete the changeover because people need to buy computers and because newspapers have established financial interests in the paper industry.
1. Which of the following is NOT an advantage of computer newspapers?
A. They are cheaper than traditional newspapers.
B. They are more convenient to read.
C. You can choose the kind of voice you want to hear.
D. You can easily save information for future use.
2. Which of the following is a reason why it will take a long time to complete the changeover?
A. The technology is impossible now.
B. Computer newspapers are too expensive.
C. The popularization of computers needs a long time.
D. Traditional newspapers are easier to read.
3. It can be inferred that journalists are against computer newspapers because _______.
A. they don’t know how to use computers
B. they think computer newspapers take too much time to read
C. they think the new technology is bad
D. they have been trained to write for traditional newspapers
4. We can infer from the passage that _______.
A. all technological changes are good
B. new technologies don’t always replace old ones
C. new technologies will eventually replace old ones
D. traditional newspapers are here to stay for another century
5. What is the best title of the passage?
A. Computer newspapers are well liked.
B. Newspapers of the future will be on the computer.
C. Newspapers are out of fashion.
D. New communications technology.
