The forces that make Japan one of the world's most earthquake-prone(有…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 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.

December 21, 2012 marks the completion of the 5,125 year Great Cycle of the Ancient Maya Long Count Calendar.
Rather than being an end-point, this cycle that is closing is naturally I followed by the start of a new cycle. What this new cycle has in store for humanity is a mystery that has yet to unfold...
The recent 2012 movie serves to alert a targeted 140 million people, in case they too haven't already heard the news. Unfortunately, however, the movie does a disservice because it distorts the message of this ancient prophecy (预言) by associating it with fear and destruction, as described by the movie's global disaster scenario (场景), rather than the themes of transformation and renewal the prophecy is actually based on.
In other words, the global scenario of the 2012 movie is not based on any facts. As Emmerich clarifies,“We only used the fact that the Mayan calendar ends. That gave us the year.” Emmerich said after checking out the range of 2012 books on Amazon, he realized, “...there are so many (theories) that, in a way, you can just create your own.” He shares that “2012” was tacked on as a title to his disaster movie because it is something “people believe” and it made the movie seem more “real.”
Interestingly, Emmerich's underlying motivation for the movie seems to be genuine concern about the course we are all on as modern society. As he states, “I hope we are not ruining our planet. I really believe that, if we keep going and doing what we are doing, we will not be leaving the planet how it should be, for our kids. That has been going on for generations. It just very sad to see and read the news, every day, and see what these people are fighting over. It's like they don't understand that the clock is ticking.”

A. the world will end with many disasters

7. Which of the following is TRUE about the movie 2012?
A. It is intended to explore what is in store in the new cycle.
B. It tells us about the Ancient Maya Long Count Calendar as it is.
C. It is just based on the director's ideas.
D. It describes the ancient prophecy vividly.
8. What Emmerich says suggests that ________.
A. he is quite concerned about the present situation on the earth
B. he is regretful that people have misunderstood his movie
C. he himself believes what is described in the movie
D. he just wants to attract viewers by the disaster scenario

查看习题详情和答案>>Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品) of technological developments in the space.
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

The sea has always interested man. From it he can get food, minerals, and treasure. But he could not go far beneath its surface.
However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.
A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea.
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜水夫病). The bends can cause a diver to double up in pain.
A. His body is under great pressure.
B. Scientists are trying to find more about the sea.
C. For thousands of years, he could sail on it.
D. They can even kill him.
E. He can wear a diving suit and have air pumped to him from above.
F. The water pressure can cause a diver to breathe with difficulty.
G. Man wants to explore deep into the sea.
