Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water．But it also leads to a fossil fuel．Natural gas is considered the cleanest of the fossil fuels, the fuel created by plant and animal remains over millions of years．Burning it releases fewer pollutants than oil or coal．The gas is mainly methane （甲烷）．It produces half the carbon dioxide of other fossil fuels．So it may help cut the production of carbon gases linked to climate change．
Russia is first in what are called "proved reserves" of natural gas．The United States is sixth．Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America．They drilled straight down into formations where gas collects．As these supplies were used up, big drillers looked for similar formations in other countries．
But now the industry is taking a new look．Companies are developing gas supplies trapped in shale （页岩） rock two to three thousand meters underground．They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock．This causes the rock to fracture, releasing the gas．Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the south-central states．Gas shale exploration is being done mainly by small to medium sized companies．Eric Potter, a program director, says more than half the gas in the United States is now coming from these new reserves．
But hydraulic （液压的） fracturing can also produce debate and anger over the risk of groundwater pollution．This method of drilling is not federally supervised under the Safe Drinking Water Act．Some in Congress want to end that exemption （豁免） from the law．
Natural gas provides Americans with about one fourth of their energy．And, unlike oil, most of it is produced in America．Gas producers invested heavily in reaching new supplies when prices were high．But prices are down sharply now because the depression cut demand for energy．So energy expert Eric Potter says it is too early to know how the changing market prices will affect the market for gas shale exploration．
45．We can learn from the first paragraph that ________．
A．natural gas releases methane and carbon dioxide
B．natural gas is considered as the cleanest energy
C．natural gas is more environmentally friendly than other fossil fuels
D．natural gas is a renewable source of energy
46．The word “fracture” in Paragraph 4 probably means _______．
A．create B．break C．change D．decrease
47．Gas shale exploration may cause disagreement because ______．
A．it may cause water pollution B．it brings too high profits
C．it breaks the law D．it is out of states’ control
48．According to Eric Potter, the new gas shale exploration ______．
A．will provide America with about one fourth of their energy
B．will increase demand for energy
C．will make gas producers invest a big sum of money
D．may be influenced by the changing market prices

Every people has its own way of saying things, its own special expressions. Many everyday American expressions are on colors.
Red is a hot color. Americans often use it to express heat. They may say they are red hot about something unfair. When they are red hot they are very angry about something. The small hot tasting peppers found in many Mexican foods are called red hots for their color and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland jazz.
Pink is a lighter kind of red. People sometimes say they are in the pick when they are in good health. The expression was first used in America at the beginning of the twentieth century. It probably comes from the fact that many babies are born with a nice pink color that shows that they are in good health.
Blue is a cool color. The traditional blues music in the United States is the opposite of red hot music. Blues is slow, sad and soulful. Duke Ellington and his orchestra recorded a famous song – Mood Indigo – about the deep blue color, indigo. In the words of the song: “You ain’t been blue till you’ve had that Mood Indigo.” Someone who is blue is very sad.
The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has a sick feeling stomach may say she feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green.
Sometimes a person may be upset because he does not have something as nice as a friend has, like a fast new car. That person may say he is green with envy. Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because that is the color of the back side of the paper money.
The color black is used often in expressions. People describe a day in which everything goes wrong as a black day. The date of a major tragedy is remembered as a black day. A blacklist is illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.
If you had your wallet stolen while doing some shopping, you may call it .
A．a white day B．a black day C．a red day D．a green day

ARLANDA, Sweden （Reuters Life!）—Many people hate the idea of having to sleep on a plane. But Swedish entrepreneur Oscar Dios thinks they can be persuaded otherwise and he has created a new kind of hostel to prove it.
Dios says it is the world’s first jumbo （unusually large） jet hostel, an actual jet-plane at Sweden’s main airport outside Stockholm which has been changed into a 25- room guesthouse that sleeps as many as 72 people.
“I learned about this plane that was standing deserted at Arlanda airport and I’ve been trying the concept of hostels in many different houses and buildings,” he told Reuters. “I thought, ‘Why not a plane?’”
Jumbo Hostels opened for business on Thursday, giving customers the chance to check in and sleep in a room that can best be described as comfortable.”
“The most challenging part with this project is trying to build something inside a metal hull（壳） – it’s just really, really tight.”
The jet, which was originally produced for Singapore Airlines, was taken out of service in 2002. It is held on a concrete foundation with the landing gear secured in steel cradles.
One feature of the hostel is its price – a room starts at 350 Swedish crowns （about $ 41）, which is a lot less than hotel rooms outside of major airports.
Another feature is that customers can get married on the wing of the plane and stay in the plane’s more luxurious honeymoon suite （套房）.
Instead of walking down the aisle in the church, lovebirds can take what Jumbo Hostels calls the “wing walk,” where they can be joined in great happiness at the wing tip. The hostel has someone ready to perform the ceremony.
But in some respects this hostel remains a plane – most customers have to share the jet’s nine bathrooms and the staff only wear air host and hostess outfits. The only room that has its own bathroom is the honeymoon suite.
Which of the following is not true?
A. The jet plane was out of use for over eight years
B. The hostel provides ten bathrooms for customers
C. The rooms in the hotel are comfortable
D. The hostel lies at Arlanda airport in Stockholm
One of the features of the plane hostel is that .
A. air hostesses can offer good service
B. a wedding ceremony can be held on the wing
C. customers can sleep in comfortable rooms
D. the staff can have a “wing walk”
Why does Oscar Dios make jet plane hotel?
A. Because he is fond of plane very much.
B. Because he is very curious
C. Because he wants to earn more money.
D. Because he likes trying the concept of hotel in many different things.
The writer mainly wants to .
A. call on people to make use of the deserted things
B. describe a wonderful place for weddings
C. introduce a new kind of hostel
D. prove people can sleep on a plane

Thirty- two people watched Kitty Genovese being killed right below their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in gunman cruelty? Was it lack of feeling about one’s fellowman?
“Not so,”say scientists John Barley and Bib Fatane. These men went beyond the headlines to research into the reasons why people didn’t act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency（紧急情况）. Suppose you see a middle-aged man fall to the side - walk. Is he having a heart attack? Is he in a coma（昏迷） from a headache? Or is he about to sleep off a drunk? Is the smoke coming into the room from a leak（漏洞）in the air conditioning? Is it “steam pipes”? Or is it really smoke from a fire? It’s not always easy to tell if you are faced with a real emergency. Second, and more important, the person faced with an emergency must feel personally responsible（负责任的）. He must feel that he must help, or the person won’t get the help he needs.
The researchers found that a lot depends on how many people are around. They had college students in to be “tested.”Some came alone. Some came with one or two others. And some came in large groups. The researchers started them off on the “tests.”Then they went into the next room. A curtain divided the “testing room”and the room into which they went. Soon the students heard a scream, the noise of bookshelves falling and a cry for help. All of this had been prerecorded on a tape recorder.
Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped.
In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn’t. They do not feel any direct responsibility.
Are people bothered by situations where people are in trouble? Yes. Scientists found that the people were shocked, they sweated, and they had trembling hands. They felt the other person’s trouble. But they did not act. They were in a group. Their actions were shaped by the actions of those they were with.
60. The purpose of this passage is ________.
A. to explain why people fail to act in emergencies
B. to explain when people will act in emergencies
C. to explain what people will do in emergencies
D. to explain how people feel in emergencies
61. Which of the following is NOT true?
A. When a person tries to help others, he must be clear that there is a real emergency.
B. When a person tries to help others, he should know whether they are worth his help.
C. A person must take the full responsibility for the safety of those in emergencies if he wants to help.
D. A person with a heart attack needs the most.
62. The main reason why people fail to act when they stay together is that ________.
A. they are afraid of emergencies
B. they are not willing to get themselves involved
C. others will act if they themselves hesitate
D. they do not have any direct responsibility for those who need help
63. The author suggests that ________.
A. we shouldn’t blame a person if he fails to act in emergencies
B. a person must feel guilty if he fails to help
C. people should be responsible for themselves in emergencies
D. when you are in trouble, people will help you anyway
