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 (過濾) 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(便攜的), 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?”

The iPhone, the iPad: each of Apple’s products sounds cool and has become a fad(一時的風(fēng)尚). Apple has cleverly taken advantage of the power of the letter “i” –-- and many other brands are following suit. The BBC’s iPlayer --- which allows Web users to watch TV programs on the Internet ---used the title in 2008. A lovely bear --- popular in the US and UK --- that plays music and video is called “iTeddy”. A slimmed-down version(簡裝本) of London’s Independent newspaper was started last week under the name “i”.
In general, single-letter prefixes(前綴) have been popular since the 1990s, when terms such as e-mail and e-commerce(電子商務(wù)) first came into use.
Most “i” products are targeted at （針對）young people and considering the major readers of Independent’s“ i”, it’s no surprise that they’ve selected this fashionable name.
But it’s hard to see what’s so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King’s College, London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn’t have one clear definition（定義）,” he says.
“However, thanks to Apple, the term is now connected with portability (輕便) .”adds Thorne.
Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.
Along with “Google” and “blog”, readers of BBC Magazines voted “i” as one of the top 20 words that have come to define the last decade(十年).
But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.
小題1:People use iPlayer to __________.
A．listen to musicB．make a call
C．watch TV programs online D．read newspapers
小題2:We can infer that the Independent’s “i” is designed for _________.
A．young readersB．old readersC．fashionable womenD．engineers
小題3:The underlined word “ambiguous” means “__________”.
A．popularB．uncertainC．clear D．unique
小題4: Nowadays, the “i” term often reminds people of the products which are __________.
A．portableB．environmentally friendlyC．a(chǎn)dvancedD．recyclable
小題5:The writer suggests that __________.
A．“i” products are often of high quality
B．iTeddy is alive bear
C．the letter “b” replaces letter “i” to name the products
D．the popularity of “i” products may not last long

Now she's Britain's richest woman - worth $1 billion, according to Forbes magazine - and her seven Potter books have sold more than 335 million copies worldwide.
In an interview with The Associated Press last month, Rowling said she believed she was unlikely to repeat the success of the Potter series, but confirmed she had plans to work on new books.
"I'll do exactly what I did with Harry - I'll write what I really want to write," Rowling said.

MUMBAI, India —The children in their party clothes on the stage were very excited when they received the award. And the two of them said, "It’s unbelievable!"
Nine-year-old, Rubina Ali, and Azharuddin Ismail, 10, were living a very different life and obviously loving every minute of it. The two, some of the child stars of the Oscar-winning Slum dog Millionaire(《貧民窟的百萬富翁》)movie, know the Indian slums very well. That was where they grew up, and it is where they will return at the end of their Hollywood dream trip.
But before going back home, there was an interview with the host, Ryan Seacrest. During the interview they smiled and repeated their disbelief in what was happening to them. To their surprise, their movie won first place in the Oscars. When the two received the award, it was late morning in the children’s home city of Mumbai, where family, friends and many fellow residents of the slums watched the result from Hollywood.
"I don’t really know what the Oscars are," Rubina’s mother said. "I’m just glad my daughter looks happy, though she told me she missed Indian food."
"Our children lead a dog’s life," Rubina’s mother said, pointing out the rubbish everywhere, the open drains (下水道) and the lack of education opportunities.
In a few days they will be back in Mumbai and back in the slums which are their home. Fortunately, according to media reports, the movie’s director, Danny Boyle, has promised to help the children chosen from the slum and make sure they will go to a proper school.
The two don’t need to worry about their daily lives because of the Oscar success of Slum dog Millionaire. But the poverty and lack of opportunity —the central theme of the movie—is always all around.
小題1:Which of the following is NOT true about the two children?
A．They were the only two child stars in the movie, Slum dog Millionaire.

According to an English newspaper, scientists could begin cloning human embryos in Britain in 2001. It is understood that the government has already agreed to use Frankenstein’s technology, believing the benefits are more important than ethical （倫理的）concerns .Researchers think it will be possible to grow brain tissue to cure the diseases that are likely to get worse as time passes like Alzheimer’s , and produce “spare part” organs like hearts and kidneys for transplant （移植）.
Ministers are aware that the change in the law will be as controversial as the law which legalized abortion (墮胎）more than 30 years ago. Some politicians reacted angrily , arguing that the government had already made up its mind without discussion. Church leaders and anti-abortion campaigners have long expressed their horror at the plans, arguing that even the earliest embryos are forms of human life.They believe that getting an embryo from cells is morally unacceptable . And it will also cause arguments about how far scientists should interfere with nature and lead to accusations that they  are “playing God”.
The cloning of human embryos to provide spare parts is regarded by most experts to be the most important step forward in the 21st century medicine. Scientists say treatment of diseases such as Alzheimer’s and Parkinson’s will be the first application of cloning. The ability to clone embryos was first achieved by scientists in Scotland in the late 1990s and now the ability to grow stem cells into tissues and organs is being developed by American researchers. Combining the two technologies will mean an end to long waits for organs from donors and problems caused by rejection (排異反應(yīng)） of transplanted tissues by the body.
Ian Wilmut, the man who cloned Dolly the sheep, has warned that British experts will go to America, where such work is legal, if the government does not permit it.
小題1:The government has decided to allow scientists to clone human embryos because they think that ____.
A．Frankenstein’s technology is advanced
B．Its advantages are more important than its disadvantages
C．Diseases like Alzheimer’s are a serious problem in their country
D．They can make a lot of money from it
小題2:The underlined word “they”in Paragraph 2 refers to ______.
A．MinistersB．Scientists
C．Church leadersD．Anti-abortion campaigners
小題3:Which of the following statements is NOT true according to the passage?
A．Most experts think that the cloning of human embryos is beneficial.
B．Politicians were in favour of the government’s decision.
C．It is legal for scientists to clone embryos in America now.
D．American researchers are developing the ability to grow stem cells into tissues and organs.
小題4:What’s the best title for this passage ?
A．Science of cloning.
B．Cloning and abortion
C．Cloning human embryos
D．the argument between politicians and scientists

Ethiopia has greatly reduced its death rates for children under the age of five years during the last two decades, new UN statistics show. The report says Ethiopia has cut the number of child deaths, by two thirds or so, to 68 per 1,000 births compared to that in 1990.
The government owed the improved figures to its growing economy. Despite the reduction, the UN Children's Fund said Ethiopia needed to do much more to improve health facilities(設(shè)施) for pregnant women.
Ethiopia is one of Africa's poorest states, although it has experienced rapid economic growth in recent years and is one of the continent's leading coffee producers. Its economy centers around agriculture, which in turn relies on rainfall.
The BBC's Emmanuel Igunza in the capital, Addis Ababa, says Ethiopia was once representative of poor nutrition in Africa. But the latest UNICEF(聯(lián)合國兒童基金會) figures show Ethiopia is one of the few African countries on the path to realizing the development goal of reducing child death rates, he says.
Ethiopia's Health Minister Kesetebirhan Admasu said increasing family incomes had helped improve people's health. "This has also resulted in better nutrition for children and women; this has translated into better medical conditions —— all these have a direct or indirect influence on the survival of children," he told BBC Africa. He said the government has also been "aggressively expanding its primary health care network". 
"We have now 93% coverage( 覆蓋) of one health centre for 25,000 people, which basically means one health facility within a 7km area," he said.
小題1:How many in 1000 births would die in Ethiopia in 1990?
A．a(chǎn)bout 680B．a(chǎn)bout 330C．a(chǎn)bout 68D．a(chǎn)bout 200
小題2:Which of the following statements is true?
A．Ethiopian children benefit from its fastest economy growing.
B．Ethiopia has a long way to go to improve health facilities.
C．Ethiopia is the economic center because of its rich rainfall.
D．Ethiopia has already become a rich state in Africa.
小題3:What do we know according to the latest UNICEF figures?
A．Many African countries have high child death rates now.
B．Ethiopia is the only country that has reduced child death rates.
C．Ethiopia is the most successful in reducing child death rates.
D．Ethiopia was once known for its poor nutrition in Africa.
小題4:What Kesetebirhan Admasu said shows that_______.
A．a(chǎn)gricultural incomes have helped improve all the people's health in Africa
B．now the health care network is perfect in Ethiopia
C．93% of the 25,000 people enjoy health centers in Ethiopia
D．the government has been taking active measures to improve people's health

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, family life was more accommodating. 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 annually come from abroad to spend their academic year in the United States, as well as the thousands more who participate 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.
In searching for host families, who usually receive no pay, exchange programmes are increasingly broadening their appeals to include everyone who has the ability to do it.
“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 academic 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 Porst from Denmark.
小題1:Vickie Weiner is the person who ________.
A．works for a programme called LECB．works for a programme called ASSE
C．is 25 years old D．hosts foreign students
小題2: From the passage we can learn that at the beginning of the exchange programmes_______.
A．a(chǎn)ll the families could host foreign students
B．only young couples could host foreign students
C．only those who were retired could host foreign students
D．those who were not too old could host foreign students
小題3:Which of the following is the best title of this passage?
A．US Struggles to Find Host Families
B．Idea of Hosting Students Is Different
C．Foreign-exchange Program Is Going On
D．Exchange Students Keep Old People Young
