President Barack Obama rode a bicycle at the White House Science Fair on April 22. But it wasn’t an ordinary bike. As he pedaled, the President stayed in place, while the energy from his pedaling powered a water filtration (过滤) system. He was testing an invention created by a team of 14 students from Northeast High School, in Oakland Park, Florida.
Payton Karr, 16, and Kiona Elliot, 18, attended the fair as representatives of the project.“We were hoping President Obama would ride the bike, but we didn’t actually expect him to,” Payton told TFK. “ It really meant a lot.” Kiona agreed. “It was pretty awesome to see the invention, which was invented by a group of 14 high school students and one teacher, along with the help of community members, got the interest of the leader of our nation,” she said.
The project was an idea that came about after one of the Northeast students, Kalie Hoke, visited Haiti after the terrible 2010 earthquake and saw how difficult it was to find clean water. The students invented a portable(便携的), bicycle-powered emergency water filtration system, which can provide 20-30 people with drinking water in a 15-hour period. The teens hope their invention will one day be used by relief organizations like the Red Cross. “ They can take it to places after natural disasters so that water can be clean for the people there,” said Payton.
Payton and Kiona were among the 100 students from more than 40 states invited to the third annual White House Science Fair, in Washington, D.C., which is also attended by leaders in science and education. President Obama started the event in 2010 to stimulate students interested in STEM (Science, Technology, Engineering, Maths).“Well, if you’re a young person and you produce the best experiment or design, you ought to be recognized for that achievement,” Obama said when he first announced the fair.
President Obama praised the projects during a speech to attendees after the fair. “The science fair projects of today could become the products and businesses of tomorrow,” he said. “If you’re inventing things in the third grade, what are you going to do by the time you get to college?”

We might not be alone in the universe. Actually, it may be confirmed as a very crowded place by new computer models developed to help identify habitable planets.
Estimates of places where life can exist have been based on the possibility of them having surface water. But software recently developed by the Aberdeen University allows researchers to identify planets with underground water kept liquid by heat from planets.
Water is fundamental for life and planets too close to the sun lose water to the atmosphere through evaporation. On the other hand, planets located in distant reaches from their star have their surface water locked away as ice.
Sean McMahon, who is carrying out the work, explained: "Traditionally people have said that if a planet is in this Goldilocks zone—not too hot and not too cold—then it can have liquid water on its surface and be habitable."
But this concept might change when considering that planets can receive two sources of heat—heat direct from the star and heat generated deep inside the planet.
It is easy to observe it in our own planet. As you go down through the crust (壳) of the Earth, the temperature gets higher and higher. Even when the surface is frozen, water can exist below ground.
There could be immense quantities of water in fact—full of primitive life.
Professor John Parnell, also from Aberdeen University said: "There is a significant habitat for microorganisms below the surface of the Earth, extending down several kilometres".
"And some believe that the majority of life on Earth could even reside in this deep biosphere."
So the Aberdeen team are developing models to predict which distant planets might harbour underground reservoirs of liquid water with the possibility of alien life.
【小题1】What is considered as the symbol of life existence traditionally?
| A．Solid water on its surface. | B．Solid water below ground. |
| C．Liquid water below ground. | D．Liquid water on its surface. |
| A．To prove that there is majority of life on Earth. |
| B．To prove that life may also exist in other planets. |
| C．To prove that there is primitive life down through Earth. |
| D．To prove that there is a habitat for microorganisms below Earth. |
| A．Planets can lose water through evaporation. |
| B．Planets can receive heat direct from the star. |
| C．Planets can have their surface water locked away as ice. |
| D．Planets can receive heat generated deep inside the planet. |
| A．They will help identify planets where there is life. |
| B．They will help researchers find Goldilocks zones. |
| C．They have helped find some significant discoveries. |
| D．They have already located some habitats for life. |

It was reported last week that developers could take photos from Apple mobile and Google Android devices without the phone owners knowing that the images were being taken. In Apple’s case, developers can also obtain the location information for each photo.
Senator(参议员) Charles Schumer said in a telephone interview that his office had spoken with officials at both Apple and Google on Monday.
“We asked them if they could find a way on their own to prevent Apple from having access to private information,” Mr. Schumer said. “They were friendly and open to the idea that this ought to be changed.”
On Sunday, Mr. Schumer said that he planned to send a letter to the Federal Trade Commission asking the agency to investigate Apple and Google after the privacy concerns came to light. Claudia Bourne Farrell, an F.T.C. spokeswoman, said the agency had received the letter but she could not comment further.
“It worries people to think that one’s personal photos, address book, and who knows what else can be obtained and even posted online without permission,” Mr. Schumer wrote in his letter to the F.T.C. “If the technology exists to open the door to this kind of privacy invasion, then surely technology exists to close it, and that’s exactly what must happen.”
Mr. Schumer said if Apple and Google could not come to an agreement to fix the problem, then he would be forced to take the issue further.
He said other companies had been willing to work with his office to fix issues. “I’m optimistic that we can get this changed without any regulation,” he said. “If it’s not changed, then we’ll turn to the F.T.C., and if that doesn’t work then we’ll consider legislative approach.”
The F.T.C. has warned companies to try to be more vigilant(警醒的) in their efforts to protect consumers when it comes to privacy.
【小题1】The senators spoke with officials at both Apple and Google___________.
| A．to urge them not to invade consumers’ privacy |
| B．to discuss whether it is illegal to have access to private information |
| C．to stop them from developing the technology of taking photos |
| D．to keep them from obtaining the location information for each photo |
| A．Privacy invasion from Apple has existed for a long time. |
| B．Mr. Schumer takes the privacy concerns caused by Apple and Google seriously. |
| C．Privacy invasion from Google has existed for a long time. |
| D．Apple and Google have decided to make a change. |
| A．In a newspaper. | B．In a travel brochure. |
| C．In a science report. | D．In a textbook. |

Yasuda is 95 years old. Looking for easier ways to search the Web and send email, he bought Apple’s iPad. The company has sold 3.27 million iPads since they entered the market in April. Although it’s impossible to know with certainty how many seniors (老年人) are buying them, evidence suggests that it’s a hit with seniors.
The iPad’s intuitive interface (直观界面) makes it attractive to seniors around the world, says Takahiro Miura, a researcher at the University of Tokyou. “The iPad is a good tool for seniors because it’s very easy to use,” he says. “Unlike the PC, it doesn’t require former knowledge.”
James Cordwell, a researcher in London, says the iPad’s popularity with seniors is helping Apple reach beyond its traditional base of young customers. “The world’s population, especially in developed markets, is getting older. It’s probably a market where Apple has least entered, ” Cordwell says. Senior users are “a key source of growth for them in the future.”
Seniors make up about 22 percent of the population in Japan. They may prove that seniors are willing to accept the iPad. Besides the customer group under 30, they spend more than any other group in the country, according to a report. Motoo Kitamura, 78, a former gas salesman, bought an iPad to help him communicate with his 2-year-old grandson and prevent him from experiencing some of the mental problems that sometimes come with getting older. “Trying new things like that is good mental exercise,” he says.
【小题1】The underlined part “a hit” in Paragraph 1 probably means ______ .
| A．a sudden attack | B．a heavy burden | C．quite popular | D．very familiar |
| A．It has intuitive interface. |
| B．It is easy to operate. |
| C．Beginners can use it without similar experiences. |
| D．People can use it as a way to do mental exercise. |
| A．People above thirty are Apple’s largest customer group in Japan. |
| B．The traditional customers of Apple’s products are usually the young. |
| C．Seniors will soon grow into Apple’s largest customer group. |
| D．Seniors in Japan are fond of buying latest hi-tech products. |

Thousands of people living in the Chinese capital will celebrate the start of the Chinese New year by heading for the ski resorts (滑雪场). Never mind that Beijing’s dry weather seldom produces snow. It is cold enough in winter for snow-making machines to make a covering for the hills north to the capital. And the rapid growth of a pleasure-seeking middle class has formed the basis for this new craze(热潮）.
Since Beijing’s first ski resort was opened ten years ago, the sport has enjoyed astonishing increase. There are now more than a dozen resorts. Clothes markets in the city have added bright colored ski suits to their winter collections. Mr. Wei, a manager of a newly-opened ski resort in Beijing, sees the growth of an industry that could soon lead Chinese to head for the ski resorts of Europe. In recent years ski resorts offering natural snow have opened in China. But many are in faraway areas of the country and can’t really match the equipment and services of some ski resorts in Europe.
Beijing’s skiing craze is partly a result of the recent increase in private cars. This has led to the growth of a leisure industry in the capital’s suburbs, which until the late-1990s were unreachable to ordinary people. According to Mr. Wei, about 40% of the visitors to his resort come in their own cars. The rest are bused in by schools, businesses or government offices.
The problem is making money. Starting ski resorts requires quite a lot of money: hiring land from the local government, preparing the hills, buying snow machines, making sure there are enough water and electricity to run them, and buying ski equipment for hiring out to customers.
The ski resort where Mr. Wei works cost nearly $4m to set up. And, as so often in China when someone comes up with a good idea, many others rush in and price wars break out. Beijing now offers some of the cheapest ski training classes in the world, though with most people rather new to the sport, expecting a few more doing the same job.
【小题1】What does this text mainly talk about?
| A．Convenience for skiers brought about by private cars. |
| B．Skiing as a new way of enjoying one’s spare time. |
| C．Things to be considered when starting a ski resort. |
| D．A sudden increase of ski training classes in Beijing. |
| A．To visit more ski areas. |
| B．To ski on natural snow. |
| C．For a large collection of ski suits. |
| D．For better services and equipment. |
| A．Difficulty in hiring land |
| B．Lack of business experience |
| C．Price wars with other ski resorts |
| D．Shortage of water and electricity |

A sixth of undergraduates in Beijing this year have registered at driving school. The students, mostly from majors such as business management or international trade, will finish their driving courses within 20 days or so.
Training costs have dropped to 2, 600 yuan for students, according to the Haidian Driving School in Beijing. The price is not really low, but students will accept it, seeing it as an investment （投资）in their future. Familiarity with the operation of computers and fluent English are the basic skills graduating students need to find a job. But a driver’s permit has become another factor.
“In the job market, owning a driver’s permit sometimes strengthens a graduating student’s competitiveness for a good position, ”says Zhou Yang, an undergraduate at the China University of Political Science and Law.
Cars will become a necessary part of many people’s lives in the coming years, and it is difficult to get a permit out of campus because of the pressures on working people’s time. “Having a fulltime job after graduation offers limited time to learn to drive. We senior students have plenty of spare time, plenty of opportunity to learn. ”Zhou says.
Xu Jian, an official at the driving school, said undergraduates were very able and serious, and could grasp in an hour what ordinary people took four hours to learn. In this driving school, middle-aged people, young women and college students are the main customers.
To get a driver’s permit, a beginner is now required to have at least 86 hours’ practice before the final road test.
【小题1】The undergraduates are learning to drive because ________.
| A．they like to drive cars |
| B．they need this skill to find a good job |
| C．they will not have any time to learn to drive after they have found a full-time job |
| D．most of them will be able to buy cars in the future |
| A．It is better to learn it at college than at work. |
| B．Young people have an advantage in learning to drive. |
| C．It is a waste of money and time to learn to drive. |
| D．They will spend three times more time to learn to drive than usual. |
| A．Students Learn to Drive. |
| B．Students Pay Less to Learn to Drive Now. |
| C．It is Better to Learn to Drive at Colleges. |
