C

Could the solution to world future energy needs lie in the ocean? It’s possible.

We are not talking about oil, but another potential untapped energy resource called “methane hydrates”.

Methane hydrates are hard, ice-like white solids that form naturally in deposits (沉積物) on ocean floors. They arecomposed of water and highly concentrated methane produced by the microorganisms living in the deposits.

The remarkable thing is that you can hold a flame to a piece of methane hydrate and it will catch on fire. It’s been called “burning ice.”

Methane hydrates are spread around the world. These deposits may in the future become a very important fuel resource. One researcher calculated that a small area off the Southeastern coast of America may contain methane hydrates equal to 30 times the annual U.S. consumption of natural gas.

Right now there are very significant technical and financial challenges facing us before we could exploit this as a resource. Scientists around the world are studying these challenges. One big issue is how to get these methane hydrates off the ocean floor, causing undersea landslides and tidal waves.

Another issue is how to handle the matter after it is brought up. It’s also unclear whether it would make more sense to “mine” solid hydrates or tap the gases found with them. And many deposits may occur in low concentrations with no commercial potential.

Japan, which has no oil supplies of its own, has thrown itself into burning ice research because it has deposits off its shores which could make Japan less dependent on foreign suppliers of oil.

The U.S. Department of Energy and Congress are also supporting research. However, the US administration’s energy policy is focused on traditional fossil (化石) fuels. And at least for now, developing burning ice into a fuel source isn’t high on the energy industry’s list. But if natural gas continues to rise in price, exploiting burning ice might become economically practical.

59. What’s the meaning of the underlined word in Paragraph Two?

       A. not existed                B. Unseen          C. available but not used              D. unreal

60. What can you learn from the text?

       A. Burning ice has been used in some countries.

       B. Applying burning ice tops the energy list in America.

       C. Burning ice exists in few countries.

       D. There are still some problems in developing the burning ice

61. Why has Japan already begun to develop the burning ice?

       A. It is a developed country.  B. They want to help other countries.

       C. It lacks oil supplies of its own. D. America asked Japan to do so.

62. Which one is the best title of the text?

       A. World Energy Shortage           B. Burning Ice Holds Hope as Fuel Source

       C. Methane Hydrates                D. Methane Hydrates Spread around the World

To most of us, sharks are _31__ most dangerous fish in the sea, for they attack humans. However, according to Doctor Clark, ___32___ has studied the behavior of sharks for twelve years, humans are not normally on a shark’s menu. What ___33___ sharks feed on? Mainly fish and other small sea animals. Doctor Clark also found that sharks don’t eat as much food ___34___ people think. For instance, a nine-foot shark only needs two pounds of food a day to keep __35____ (health). But he says sometimes sharks starve and at other times they fill __36____ with what they have killed. Around the world, there are about 100 shark attacks on humans each year, ten of which prove fatal (致命的). But consider this: in the U.S. alone (僅僅), about 3 million people are __37____ (bite) by dogs each year. Of these, 13 people die. “If a shark bites you,” says Doctor Clark, “the reason is   38   it mistakes you as its natural food.” For example, if you went underwater fishing and saw a shark, you could be in trouble. The shark might go for the ___39___ (injure) fish you had attacked and take a big bite of you at the same time. __40____ you went into a shark’s territory (領(lǐng)地) and threatened it, it might try to bite you. That’s because sharks are territorial and tend to guard their territory. Like dogs, they protect the area that they think is theirs.
