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 fordecades that ants-which are highly sensitive to ecological change can provide a near-perfect barometer of the state of an ecosystem. Only certain species, forinstance, will continue to thrive at a forest site that has been cleared of trees. Others will die out forlack 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. _____. Ants are used simply because they are so common and comprise so many species.Where mine sites are being restored, forexample, 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 foryears 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 professorof 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 orthe laboratory time needed to sift results fora comprehensive survey. The cost stems, also, from the scarcity of ant specialists. Employing those people are expensive. 【单选题】

2、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a majorcontributorto the planet\'s increasing temperature rise orglobal warming. Molecule formolecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. and without greenhouse gases to trap the sun\'s heat and warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal forenergy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame forthis often focuses on big industries and gas-guzzling vehicles. But agriculture plays a majorrole, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, forexample), and it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a majorfactorof causing the global warming.Nothing has been mentioned in the passage about ____ .【单选题】
A.one of tire majorcontributors
B.the ever-increasing atmospheric concentration of greenhouse gases
C.big and hefty cows
D.livestock\'s normal digestion process
E.how to cut down the cattle population
F.big industries and gas-guzzling vehicles

3、DyslexiaAs many as 20% of all children in the United States suffer from some form of the learning disorcercalled dyslexia.Experts on dyslexia say that the problem is not disease. They say that persons with dyslexia use information in a different way. One of the world\'s great thinkers and scientists, Albert Einstein was dyslexic. Einstein said that he never thought in words the way that most people do. He said that he thought in pictures instead. The American inventorThomas Edison was also dyslexic. Dyslexia first was recognized in Europe and the United States more than 80 year ago. Many years passed before doctors discovered that persons with the disorcerwere not mentally slow ordisabled. The doctors found that the brains of persons with dyslexia are different. In most people, the left side of the brain, the part that controls language is larger than the right side. In persons with dyslexia, the right’ side of the brain is bigger. Doctors are not sure what causes this difference. However, research has shown that dyslexia is more common in males that in females, and it is found more often in persons who are left-handed. No one knows the cause of dyslexia, but some scientists believe that it may result from chemical changes in a baby\'s body long before it is born. They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching help. After they have solved their problems with language, they often show themselves to be especially intelligent orcreative.Many great thinkers and scientists in the world are dyslexic.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:C
答案解析:题目中的关键词为great thinkers and scientists,我们在第2段中找到答案所在句。但是通过对比发现,原文中的限制词是one of,而题目中却是many。再仔细阅读原文发现,文中仅提到爱因斯坦和爱迪生为读写困难症的患者,并未讲述除爱因斯坦和爱迪生以外的思想家和科学家的情况,因此该题的答案为C。
4、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. The volcano is so inconspicuous(不显眼的) that few people know it exists. 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," orextremely 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 orso. "If nature were truly that regular and reliable, we would be clue foranother eruption soon," said Valley. "However, these processes are subject to variability, so we don\'t really know when the next eruption will happen. "_____. 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】

答案解析:第50题所在段的前面两段介绍了黄石公园火山以前喷发时的可怕情景。第50题所在段也叙述了火山能量带来的好处。这是两种情景截然相反的描写,中间很可能有一句过渡句,把它们连接起来。选项E就是过渡句,应该是本题的答案。
5、Why People Use Pseudonyms (假名字)?You can\'t choose the name you are given at birth, but in many countries you can change it legally when you reach adulthood. Of course, most people never change their names even if they feel unhappy about them. However some people do take this course of action-particularly artists! What makes an artist want to change their name? Sometimes it\'s forpurely ____ reasons, such as the Nobel Prize winning poet from Chile, Neftalf Reyes. He didn\'t want his father to know he was writing poetry, so he changed his name to Pablo Neruda when he was a young man. At other times the reason may appear strange, take the case of the Portuguese poet Femando Pessoa, who wrote under 75 different names. The reason? "When I use a different name, I always write in a different way," he explained. In most cases, however , people change their names forsocial, historical, political, orcultural reasons. Here are some of the most common: reason. The person\'s real name is just too long and difficult to remember. Let\'s be honest, Madonna Louise Ciccone is not as easy to remember as just plain Madonna. and short names are much easier to remember: William Bradley became Brad Pitt and Edson Arantes do Nascimento became Pele.Sometimes names are changed formarketing purposes. Forexample, if a name sounds too foreign, it may be changed to something that is more recognizable in a market. So in the film world, Ramon Estsvez adopted the name Martin Sheen. ormaybe the artist\'s real name doesn\'t sound attractive-Chad Everett does sound a lot better than Raymond Cramton.Artists sometimes choose the name of someone they admire. Robert Zimmerman changed his name to Boo Dylan because of his admiration forthe Welsh poet, Dylan Thomas.Another reason may be practical: in the past, women found it very difficult to get published. To avoid this situation, they sometimes gave themselves men\'s names, so the English authorMary Ann Evans became George Eliot, and she did get her books published!【单选题】
A.obvious
B.economic
C.own
D.personal
正确答案:D
答案解析:本题有一定的难度,干扰项干扰较大,但比较起来,只有personal“个人的,私人的”最符合上下文逻辑,是最佳答案。
