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.

举一反三
Later that evening, I 17 told Frank what I had learned that day. After talking it over, we agreed that we knew our son much better than an IQ test. We decided that Michael’s score must have been a 18 and we should treat him 19 as usual.
We moved to Indiana in 1962, and Michael studied at Concordia High School in the same year, he got 20 grades in the school, especially in biology and chemistry, which was a great comfort.
Michael 21 Indiana University in 1965 as a pre-medical student. Soon afterwards, his teacher permitted him to take more courses than 22 . In 1968, he was accepted by the School of Medicine, Yale University.
On graduation day in 1972, Frank and I 23 the ceremony (典礼) at Yale. After the ceremony, we told Michael about the 24 IQ score he got when he was six. Since that day, Michael sometimes would look at us and say 25 , “My dear mom and dad never told me that I couldn’t be a doctor, not until after I graduated from medical school!” It is his special way of thanking us for the 26 we had in him.
Interestingly, Michael then asked for another IQ test. We went to the same clinic where he had 27 the test eighteen years before. This time Michael scored 126, an increase of 36 points. A result like that was supposed to be 28 .
Children often do as well as what adults, particularly parents and teachers, 29 of them. That is, tell a child he is “ 30 ” , and he may play the role of a foolish child.

All ray students 44 ______ diaries. However, as I read their diaries, the rosy glow was gradually 45 ______ by a strong sense of sadness.

Why do they want to do this? The sun’s rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts (霜冻) which might come at night and hurt fruit crops. They could melt (融化) dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed.

The council want people to know that everyone who feeds the pigeons makes the streets crowded (拥挤)with these birds. They hope to encourage the birds to move away from the city centre and into parks and open spaces.
Ten robotic birds have been brought into the city centre to scare the pigeons away and visitors are asked not to give the pigeons any food. The mechanical birds—known as ‘robops’—will sit on the roofs of buildings. They can be moved around to different places. They look like a peregrine falcon, which is a bird that kills pigeons. They even make noises and flap their wings to scare the pigeons. They hope that the pigeons will go away before the city becomes the European Capital of Culture in two years.

D.The pigeons like the food that people give them. |
You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays (喷) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (树脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair --- the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was hardly affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC.
Taken out of the factory and introduced to more diverse and common uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3-D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3-D printing becomes more common, it may bring about certain problems --- such as piracy(盗版). "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?
小题1:According to the article, in the future, the 3-D printing technology will ___.
A.enable people to make better purchases online |
B.be applied as widely in our daily lives as computers |
C.change the way we make many products |
D.shorten the time it takes for people to get what they buy online |
A.The 3-D printing technology was taken out ofthe factory. |
B.The 3-D printer became more affordable forconsumers. |
C.The 3-D printer was used for medical treatmentfor the first time. |
D.3-D printing technology began to be used invarious fields. |
A.By analyzing a cause and an effect. | B.By making comparisons. |
C.By giving examples. | D.By presenting research findings. |
A.Printing out everything | B.Technology in the future |
C.Online shopping disappearing | D.Great demand for 3-D printers |
