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?

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?

In a country that defines itself by ideals, not by shared blood, who should be allowed to come to work and live here? In the wake of the Sept．11 attacks these questions have never seemed more pressing．

On Dec．11, 2001, as part of the effort to increase homeland security, federal and local authorities in 14 states staged “Operation Safe Travel”---raids on airports to arrest employees with false identification．In Salt Lake City there were 69 arrests．But those captures were anything but terrorists, most of them illegal immigrants from Central or South America．Authorities said the undocumented workers’ illegal status made them open to blackmail（讹诈）by terrorists．

Many immigrants in Salt Lake City were angered by the arrests and said they felt as if they were being treated like disposable goods．Mayor Anderson said those feelings were justified to a certain extent．“We’re saying we want you to work in these places, we’re going to look the other way in terms of what our laws are, and then when it’s convenient for us, or when we can try to make a point in terms of national security, especially after Sept．11, then you’re disposable．They are whole families being uprooted for all of the wrong reasons,” Anderson said．

If Sept．11 had never happened, the airport workers would not have been arrested and could have gone on quietly living in America, probably indefinitely．Ana Castro, a manager at a Ben & Jerry’s ice cream shop at the airport had been working 10 years with the same false Social Security card when she was arrested in the December airport raid．Now she and her family are living under the threat of deportation（驱逐出境）．Castro’s case is currently waiting to be settled．While she awaits the outcome, the government has granted her permission to work here and she has returned to her job at Ben & Jerry’s．

1.How did the immigrants in Salt Lake City feel about “Operation Safe Travel”?

2.Undocumented workers became the target of “Operation Safe Travel” because ____．

3.By saying “…we’re going to look the other way in terms of what our laws are”, Mayor Anderson means “______”．
