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

In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what “keeping up with the Joneses” is about. It is the story of someone who tried to look as rich as his neighbors.
The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $ 125 a week at the age of 23. That was a lot of money in those days. He got married and moved with his wife to a very wealthy neighborhood. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants. Momand and his wife also hired a servant and gave big parties for their new neighbors.
It was like a race, but one could never finish this race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They had to move back to an apartment in New York City. Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it “Keeping up with the Joneses” because “Jones” is a very common name in the United States. “Keeping up with the Joneses” came to mean keeping up with rich lifestyle of the people around you. Momand’s series appeared in different newspapers across the country for over 28 years.
People never seem to get tired of keeping up with the Joneses. And there are “Joneses” in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.

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
