The forces that make Japan one of the world's most earthquake-prone(有…傾向的) 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(地熱的) 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 decrease 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.
小題1:What would be the best title for the text?
A.Alternative energies in Japan

Still waiting for little green men to make contact? Don't hold your breath.
A leading astronomer has concluded there probably aren't any aliens out there – meaning we are absolutely alone in the universe.
Even though there may be tens of thousands of other distant planets similar in size to Earth, the conditions on them are likely to be too hard to support life-forms such as ET.
Dr Howard Smith, a senior astrophysicist at Harvard University, believes there is very little hope of discovering aliens and, even if we did, it would be almost impossible to make contact.
So far astronomers have discovered a total of 500 planets in distant solar systems – known as extrasolar systems – although they believe billions of others exist.
But Dr Smith points out that many of these planets are either too close to the sun or too far away, meaning their surface temperatures are so bad that they could not support life. Others have unusual orbits which cause vast temperature variations, making it impossible for water to exist – the most important thing for life.
Dr Smith said, "We have found that most other planets and solar systems are wildly different from our own. It means it is highly unlikely there are any planets with intelligent life close enough for us to make contact." But his suggestions contradict other leading scientists who have claimed aliens almost certainly exist.
Only last month Professor Stephen Hawking said the fact that there are billions of galaxies out there made it reasonable to think there were other life-forms in the universe.
Researchers from the University of London have recently suggested that aliens could be living on as many as 40,000 other planets. But Dr Smith said: "Any hope of contact has to be limited to a relatively tiny space around the Earth, reaching maybe 1,250 light years out from our planet, where aliens might be able to pick up our signals or send us their own. But communicating would still take decades or centuries."
小題1:By saying "don’t hold your breath", the author advised the reader not to _____.
A.keep silentB.give upC.expect soD.be afraid
小題2:Dr Smith concludes there probably aren’t any aliens because other planets _____.
A.are too far away from the earth
B.are different from the Earth in size
C.don’t have rich natural resources
D.don’t have a suitable living environment
小題3:Researchers from the University of London are mentioned to show that ______.
A.they have better explanations about aliens
B.aliens certainly exist on many planets
C.they disagree with Dr Smith’s suggestion
D.aliens can pick up signals from the earth
小題4:What’s the main idea of the text?
A.There must be other life forms in the universe.
B.We can communicate with aliens in decades.
C.The chances of finding aliens are slight.
D.Many other planets are quite different from the Earth.

C
So long as teachers fail to distinguish between teaching and learning, they will continue to undertake everything to do for children that only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible”.
Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also a public activity. It can be seen and observed.
Learning to read, however, involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest (探索) for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”
When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of learning to read by reading.
小題1:The problem with the reading course as mentioned in the first paragraph is that
________.
A.it is one of the most difficult school courses
B.students spend endless hours in reading
C.reading tasks are assigned with little guidance
D.too much time is spent in teaching about reading
小題2:The teaching of reading will be successful if ________.
A.teachers can improve conditions at school for the students
B.teachers can enable students to develop their own way of reading
C.teachers can devise the most efficient system for reading
D.teachers can make their teaching activities observable
小題3:The underlined word “scrutiny” most probably means “________”.
A.inquiryB.observationC.controlD.suspect
小題4:According to the passage, learning to read will no longer be a difficult task when
________.
A.children become highly motivated
B.teacher and learner roles are interchangeable
C.teaching helps children in the search for knowledge
D.reading enriches children’s experience
小題5: The main idea of the passage is that ________.
A.teachers should do nothing in helping students learn to read
B.teachers should encourage students to read as widely as possible
C.reading ability is something acquired rather than taught
D.reading is more complicated than generally believed

An astronomer is making a case for launching pop singer Justin Bieber into suborbital(亞軌道的)space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager — he would come back down to Earth eventually, after all — but rather to help jump-start the emerging suborbital spaceflight industry.
It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. “If there’s more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good.”
Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport.
None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z.
Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists — but Shostak is thinking about ways to make it grow.
A celebrity launch isn't Shostak’s only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling(充滿)with cameras both inside and out, to give the public dramatic views of every mission.
Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry’s success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.
小題1:Why may Justin Bieber be sent into suborbital space?
A.To show his bravery and make him a role model for teenagers.
B.To arouse the American public’s interest.
C.To help reform the spaceflight industry.
D.To film an advertisement about space.
小題2:What can we learn about suborbital spaceflight?
A.A trip will return to Earth before finishing a lap.
B.The whole trip will leave passengers weightless.
C.Each trip can take 500 passengers.
D.The trip will be too expensive even for celebrities.
小題3:What can we infer from the text?
A.SpaceShipTwo will be the first to fly.
B.Famous people will be the main passengers in the future.
C.The space trip is still in preparation.
D.Every space trip will be made into a film.
小題4:The last paragraph suggests that _________.
A.space is too mysterious to explore
B.the suborbital market is promising
C.the spaceflight industry is more successful than people think
D.developing the industry is risky
小題5:What is the main purpose of the text?
A.To predict a change in the space market.
B.To discuss a recent launch.
C.To introduce the status of the spaceflight industry.
D.To remove public doubt about the spaceflight industry.

Almost everyone suffers from a headache sometimes.But some people suffer from repeated, frequent headaches.
What is headache? What causes it? What can be done about a headache? What research is being done on headaches?
The dictionary defines(下定義) headache simply as “a pain in the head.” What most people mean by headache is a pain which lasts several minutes or hours.It covers the whole head, or one side of it, or perhaps the front or the back of the head.To add to the confusion(困惑) about a definition, some people call tight feeling in the head a headache.
A headache is important because it can be the first warning of a serious condition which probably could be controlled if discovered early.If a person removes the warning, day after day, with a pain-killer, he may pass the point of easy control.
The professional name for covering up a symptom(癥狀) is “masking” (遮蔽).A headache specialist once said, “Masking symptoms is not the best way of treatment.” He compared taking a pain-killer for a headache before a cause is known with taking iron pills for anemia(貧血癥) while bleeding continues undiscovered.He added, “Sometimes it is wiser to stand still than to advance in darkness.
A headache is important also because it affects normal, happy living.The employee with a headache does less work.In a flash of temper he may upset his fellow workers or customers, causing a direct or indirect loss to his organization.The mother with a headache suffers and disturbs the family.She upsets her husband and children.
小題1:Which is true according to the passage?
A.Headache has no effect on others.
B.Headache may cover the whole body.
C.Headache may last several minutes or hours.
D.Headache is just the tight feeling in the head.

A.you should not advance in darkness whatever happens
B.you’d better do nothing before you know how to deal with it
C.you’d better still stand there without moving when it is dark at night
D.you should take some pain-killers for your headache if you want to cover it up
小題3:What may the writer talk about in the following paragraph?
A.Treatments of headachesB.The definition of headaches
C.Symptom of headachesD.Bad effects of a headache
小題4:The passage mainly tells us______.
A.the reason of headache

These days, young children can enjoy directly what it is like to be a marine biologist (海洋生物學家) at a marine association. What they discover can lead them to appreciate and protect the ocean and also the animals living in it.
At the present time, learning isn’t only limited to the classroom. It’s quite common for kids to learn from outdoor experiences. Teachers commonly take their pupils on field trips to museums as well as other interesting areas. If you wish to help pupils to take care of the ocean, one of the best areas to take them to is a marine association, the place where the ocean biome (生物圈) is shown.
Taking your pupils to a marine association is a prefect way to help them learn. Education professionals agree that there are topics that children can learn more successfully whenever they experience them directly.
Several organizations that focused on protecting the ocean now operate on the coast of different areas in America and all around the world. It’s quite common for marine associations nowadays to open their doors several times a week to kids, parents, and ocean lovers to learn more about the ocean biome.
A marine association has different programs for children of different ages. You’ll find programs that are developed specially for pupils. Pupils are involved in interactive (互動的) learning. This learning experience allows young children to recognize the value of the role each species performs in their environment. They not only get to research creatures from the ocean, but they also get to see, touch, and smell most of these animals and plants. This type of exposure offers students an idea about the life of a marine scientist. It could help them choose a career afterwards.
These programs are generally held on Saturdays and Sundays in order that kids and parents can have more hours in which to have fun. Teachers who want to arrange these activities for their students can call a local marine association near them.
小題1:According to the text, pupils can have a better understanding of the ocean biome by _______.
A.learning about it from books
B.going to a marine association
C.attending marine biologists’ meetings
D.taking part-time jobs at marine associations
小題2:In Paragraph 5, the author mainly wants to tell us _______.
A.the advantage of learning at a marine association
B.different activities offered by a marine association
C.a marine association’s working conditions
D.the way to develop children’s interest in ocean
小題3:The underlined word “exposure” in Paragraph 5 probably means _______.
A.the way of explaining something
B.the way of choosing a career
C.a marine association’s working condition
D.the way to develop children’s interest in the ocean
