The forces that make Japan one of the world's most earthquake-prone（有地震倾向的） countries could become part of its long-term energy solution．
Water from deep below the ground at Japan's tens of thousands of hot springs could be used to produce electricity．
Although Japanese high-tech companies are leaders in geothermal（地热的） technology and export it, its use is limited in the nation．
"Japan should no doubt make use of its resources of geothermal energy," said Yoshiyasu Takefuji, a leading researcher of thermal-electric power production．
The disastrous earthquake and tsunami on March 11, 2011 caused a reaction against atomic power, which previously made up 30 percent of Japan's energy needs, and increased interest in alternative energies, which account for only 8 percent．
Artist Yoko Ono has called on Japan to explore its natural energy, following the example of Iceland which uses renewable energy for more than 80 percent of its needs．
For now, geothermal energy makes up less than 1 percent of the energy needs in Japan, which has for decades relied heavily on fossil fuels and atomic power．
The biggest problem to geothermal energy is the high initial cost of the exploration and constructing the factories．Another problem is that Japan's potentially best sites are already being developed for tourism or are located within national parks where construction is forbidden．
"We can't even dig 10cm inside national parks．" said Shigeto Yamada of Fuji Electric, adding that regulations protecting nature would need to be relaxed for geothermal energy to grow．
Researcher Hideaki Matsui said, "Producing electricity using hot springs is a decades-long project．We also have to think about what to do for now as energy supplies will decline in the short term．"
The Earth Policy Institute in Washington, US, believed Japan could produce 80,000 megawatts（兆瓦）and meet more than half its electricity needs with geothermal technology．
Japanese giants such as Toshiba are already global leaders in geothermal technology, with a 70 percent market share．In 2010, Fuji Electric built the world's largest geothermal factory in New Zealand．
【小题1】What would be the best title for the text?

According to the United States government, people are classified as homeless if they have no place to stay and no expectation of finding a place for the next thirty days. Although technically accurate, that is an impersonal assessment of an enormous and very human problem.
The homeless population represents all of us Americans. It includes men and women, the elderly, children, and infants. Its members are from all ethnic groups. What they have in common is poverty.
Currently in the U.S., thirty-nine million people live in poverty. When money is really tight, paying the rent or buying food often becomes a choice. Government assistance in the form of food stamps does help but, as one homeless man explains, you can’t pay the rent with food stamps.
With no money for rent, the streets and homeless shelters become the alternative.
Although men make up the largest group within the homeless population, homeless women with children are rapidly joining them. In fact, one quarter of the homeless people in the U.S. are teenagers and young children.
People may become homeless for numerous reasons. However, there are certain factors that many of these individuals have in common. They include a lack of adequate education and job skills. A majority of the teenagers and adults have not completed high school.
The abuse of alcohol and drugs is also a common factor. One third of the adult homeless population abuses alcohol, while one quarter of the same group uses drugs.
Some members of this population suffer mental health problems. Within the past several years many institutions for the mentally ill have been closed and their patients sent “home”. Unfortunately, a number of those people have no home to go to and they are unable to adequately look after themselves.
Job loss in today’s economy has also become a real factor in the loss of people’s homes. The breakup of families through abandonment and divorce is also contributing factors, particularly when there are children involved. The parent who is left to care for the kids with inadequate income may be forced to depend on the homeless shelters to put a roof over their heads.
【小题1】The writer thinks that the U.S. government’s definition for the homeless shows _________.

【小题1】The underlined sentence in the first paragraph implies that _____．

This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕榈) oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO₂(carbon-dioxide)emissions(排放)from airplanes. there are a lot of hurdles (障碍)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet‘A’fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae（藻类）produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel－a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!
【小题1】．Why does Virgin Airlines try to replace normal fuel with biofuel?

Free and secure accommodation, no bills and even the odd home-cooked meal. It sounds like the perfect living arrangement for cash-strapped students.
Two mothers believe they have devised a way for struggling students to save on accommodation costs when they leave home to study at university.
Kate Barnham and Amanda Flude have launched Student Swaps, an online accommodation forum (论坛) for parents and students, in advance of the introduction in September of ￡3,000 higher education top-up fees.
Their website says, “The principle behind Student Swaps is to enable students to literally swap (交换) family homes.” The website will hold a database of students who would like to swap and link them with suitable matches. So those from one town / city could swap with those from a different town / city.
The site describes itself as offering a “cost-free accommodation alternative… at a time of growing student debt”. There is no charge for the service at the moment but Ms Barnham and Ms Flude intend to introduce a ￡10 annual fee if it becomes established.
However, the National Union of Students (NUS) has warned that, while the scheme may sound appealing to struggling freshers, it lacks any formal regulation.
Veronica King, NUS vice-president of welfare, said, “The fact that this scheme has even been suggested is evidence to the high levels of debt students now face on graduation.” Recent research has shown that students are more likely to live at home in coming years, in a bid to cut down on the cost of a degree.
“This is worrying, as it may mean that students choose their university on the basis of where it is, rather than because it offers the best course for them. It also means students will miss out on what is for some a key part of the student experience-living away from home.”
