1、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. _____. 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. This allowed scientists to gauge the pace and progress of the ecological recovery. 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.

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:F

答案解析:第46题前面的句子有certain species，后面的句子有still others，这一定是英语中“some/certain. …. others. …still others”的固定结构。仅从这一点判断，F是答案。

2、Some Unusual CelebrationsSome holidays are well - known all around the world. Among them are New Year\'s Eve Celebrations. Also days are common in honor of love and friendship, like Valentine\'s Day. Each country has its own special holidays too, to mark important events in its history. Schools, banks, and government offices all close on days like these. Some of the days people celebrate, however, are less serious. A few of them are really very strange.Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool\'s Day, for example. No one knows when or why it began. Today it is celebrated in many countries－France, England, and Australia, etc. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you?Dyngus Day in Poland seems strange, too. On this day, it is traditional for boys to pour water over the heads of girls. Here is the strangest part: they do it to girls they like.Other unusual celebrations take place in a single city or town. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. Then begins the world\'s biggest food fight. For two hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains and catch a wild goat. ____There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea for a new holiday and tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 9. That is supposed to be Toothache Day.Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.【单选题】

3、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. ____ 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. The younger group did 10 percent better when not interrupted. 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.

正确答案:F

答案解析:本题难度不是很大。可用排除法和代入法。本题的上文谈到纽约新的法律规定在走路开车时不能打电话、发邮件、听音乐，下文谈到新法律发生效力的时间，所以可以推断此处会继续跟着上文展开阐述，应该讲如果你做了会导致什么结果，回来看选项，把F代入文中，符合逻辑，答案是F。

4、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. In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems."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. ______【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:B

答案解析:由于审讯室的巨大压力，嫌疑人很可能为了逃离那种环境而承认自己本没有做过的事。因此，Kassin说，从某种程度上看，错误的妥协在那种情况下是一种理性的选择。

5、EducationWhen a teacher finds a way to make a real difference in the students\' lives that\'s what education is all about. Let me tell you a story. Back in 1944 we had a new student named Roger, he was the first black student in our school, and everyone had some pretty ignorant views on the subject of black people . The other kids weren\'t bad children; they were just copying their parents, and well, I\'m afraid most of their parents had some pretty ignorant views on the subject of black people . But as you know, when you\'re twelve years old, you\'re just starting to have your own opinions about things, and I knew this could be a very important moment in their education. I knew I could make a real difference, not only to little Roger , but to all the other kids, too, if just handled it the right way.I decided I had to try to make Roger into someone special. Not like a teacher\'s pet, I wanted the other children to ____ , not just a dark shape in the back of the room. So I went after him with questions in every class. He was a bright little boy, so it was easy enough for me to establish him as a smart person with real value. I was pretty pleased, because I could see Roger becoming more confident, and although the other kids were still not very friendly, at least they stopped being so nasty to him.But you know what really changed everything? One day I could see Roger\'s mind was wandering: and without thinking I threw an eraser in his direction. I only meant to get his attention, but the eraser hit his hand and sent his pencil flying. The whole class roared! And afterwards, of course, all the kids went up to Roger to laugh with him about it . That\'s how he became an individual, someone special, to talk to and make friends with and that\'s how I became "Dead - Eye Bean".【单选题】

A.was giving him a hard time

B.had some pretty ignorant views on the subject of black people

C.while they were enjoying the same class

D.not only to little Roger

E.start seeing him as a human being

F.all the kids went up to Roger to laugh with him about it
