1、Sleeping GiantRight now, an eruption is brewing in Yellowstone National Park. Sometime during the next two hours, the park\'s most famous geyser, Old Faithful, will begin gurgling boiling water and steam. Then, an enormous fountain will shoot high into the air .Old Faithful is not only a spectacular sight; it\'s also a constant reminder that Yellowstone sits on one of the largest volcanoes in the world. If you\'ve never heard of Yellowstone\'s volcano, you\'re not alone. _____. Yet it has erupted three times during the last 2 million years. And one of those eruptions spewed enough volcanic ash and other debris to blanket half the United States.Yellowstone\'s volcano is sometimes called a "super volcano," or extremely large and explosive caldera volcano. Three calderas make up more than a third of Yellowstone National Park. This super volcano formed over a hot spot, an extremely hot area in Earth\'s mantle. John Valley, volcano professor, said that as the crust moves across a hot spot, the hot spot melts a. section of the plate moving over it, forming "one volcano after another. "The Yellowstone hot spot melts thick continental crust, which may cause catastrophic eruptions. According to experts the eruptions that created each of the three calderas in and around Yellowstone National Park were larger than any other volcanic eruption in recorded history. The most recent eruption, which happened 640,000 years ago, produced at least l,000 cubic kilometers of ash and debris, which blanketed most of the western half of the United States. The first Yellowstone eruption, 2 million years ago, released more than double that amount of ash and debris.Geological evidence shows Yellowstone has blown its stack every 700,000 years or so. "If nature were truly that regular and reliable, we would be clue for another eruption soon," said Valley. "However, these processes are subject to variability, so we don\'t really know when the next eruption will happen. "While the active geologist processes at Yellowstone do pose some risk to tire public, they also make it a unique treasure. It is the volcanic energy that powers the geysers and hot springs, creates the mountains and canyons, and generates the unique ecosystems that support Yellowstone\'s diverse wildlife.【单选题】

2、Ants as a Barometer of Ecological ChangeAt picnics, ants are pests. But they have their uses. In industries such as training, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.It has been recognized for decades that ants-which are highly sensitive to ecological change can provide a near-perfect barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. Others will die out for lack of food. And still others will move in and take up residence.By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys. Ants are used simply because they are so common and comprise so many species.Where mine sites are being restored, for example, some ant species will recognize the stripped land more quickly than others. _____. Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That\'s the great thing about ants. "Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.Why not? Because many companies can\'t afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. Employing those people are expensive. 【单选题】

A.This allowed scientists to gauge the pace and progress of the ecological recovery.

B.Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.

C.Employing those people are expensive.

D.They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.

E.The evolution of ant species may have a strong impact on our ecosystem.

F.Others will die out for lack of food.

正确答案:A

答案解析:选项A中的ecological recovery与前面一句中的recognize相呼应，提示选项A的句子是前面句子的后续句。

3、J. K. RowlingLike that of her own character, Harry Potter, J. K. Rowling\'s life has the luster of a fairy tale. Divorced, living on public assistance in a tiny Edinburgh flat with her infant daughter, Rowling wrote Harry Potter and the Sorcerer\'s Stone at a table in a cafe during her daughter\'s naps and it was Harry Potter that rescued her.Rowling remembers that she always wanted to write and that the first story she actually wrote down, when she was five or six, was a story about a rabbit called Rabbit. Many of her favorite memories center around enjoying the fantastic adventure stories.On a particularly long train ride from Manchester to London in the summer of 1990, the idea came to her of a boy who is a wizard and doesn\'t know it. He attends a school for wizardry -she could see him very plainly in her mind. By the time the train pulled into King\'s Cross Station four hours later, many of the characters and the early stages of the plot were fully formed in her head. The story took further shape as she continued working on it in pubs and cafes over her lunch hours.Rowling was working as a French teacher when she heard that her book about the boy wizard had been accepted for publication. Harry Potter and the Philosopher\'s Stone was published in June1997 and achieved almost instant success. With the publication of the American edition, retitled Harry Potter and the Sorcerer\'s Stone, in 1998, Rowling\'s books continued to make publishing history. Harry Potter climbed to the top of all the bestseller lists for children\'s and adult books. In Britain a separate edition of the first book appeared with a more "adult" dust jacket so that grown-ups reading it on trains and subways ______.J. K.

4、A Bad IdeaThink you can walk, drive, take phone calls, e - mail and listen to music at the same time? Well, New York\'s new law says you can\'t. And you\'ll be fined $ 100 if you do so on a New York city street. The law went into force last month, following research and a shocking number of accidents that involved. people using electronic gadgets (小巧机械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. A group of 18 to 21 years old and a group of 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. ____ But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $650 billion a year, The estimate is based on surveys with office workers. The surveys conclude that 28 percent of the workers\' time was spent on interruptions and recovery time before they returned to their main tasks.【单选题】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The younger group did 10 percent better when not interrupted.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任务处理) abilities are limited.

F.And you\'ll be fined $ 100 if you do so on a New York city street.

5、Why Would They Falsely Confess?Why on earth would an innocent person falsely confess to committing a crime? To most people, it just doesn\'t seem logical. But it is logical, say experts, if you understand what can happen in a police interrogation room.Under the right conditions, people\'s minds are susceptible to influence, and the pressure put on suspects during police grillings is enormous.______ "The pressure is important to understand, because otherwise it\'s impossible to understand why someone would say he did something he didn\'t do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess. "Developmental psychologist Allison Redlich recently conducted a laboratory study to determine how likely people are to confess to things they didn\'t do. In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems. The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.Redlich\'s findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed. Redlich also found that the younger the participant, the more likely a false confession. Of the 15-to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds. "There\'s no question that young people are more at risk," says Saul Kassin, a psychology professor at Williams College, who has done similar studies with similar results. "But adults are highly vulnerable too. " Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-and still, most participants falsely confessed.Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. "In some ways," says Kassin, "false confession becomes a rational decision. "【单选题】

A.In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems.

B."In some ways," says Kassin, "false confession becomes a rational decision. "

C."It\'s a little like somebody\'s working on them with a dental drill," says Franklin Zimring, a law professor at the University of California at Berkeley.

D."But adults are highly vulnerable too. "

E.How could an innocent person admit to doing something he didn\'t do?

F.Redlich also found that the younger the participant, the more likely a false confession.

正确答案:C

答案解析:解答此题时要注意，空格处后是一段引文，而空格处前没有引文，所以此处一定是引用了某人的话，因此答案只可能在B、C、D项中。但D项只是一句引用的话，并没有提及是谁说的，这不符常理，故排除。B项虽然提到了Kassin，但没有对其身份进行说明，这也不符合“第一次提到某人是要有所说明”的习惯（实际上他出现在第五段），故排除B项，因此只能选C项，只有此项符合上下文语境。
