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 (沉积物) 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

Natural resources are things 1. exist in nature and can be used by people. Some natural resources are renewable, like trees. When one tree is cut down, we can plant a new tree to replace it. Others, 2., are not renewable, like the coal dug out of the ground. Once it is used, it is 3.. (go)

(throw) away carelessly; food is wasted just because of its poor taste; clothes are rejected 5. (simple) due to their old fashion. These valuable natural resources will run out before long 6. better use is made of them.
Actually, everyone can make contributions (贡献) to 7. (protect) our natural resources. For example, 8.riding a bicycle or walking instead of driving, we can save lots of petrol. Water is a very important natural resource because we all need 9. to stay alive. We can make wise10. (choose) to save water, like reusing the water that has been used to wash vegetables to water flowers.
