Forest fires, farming and mining destroy the rainforests.____

参考解析

解析:
根据题干信息“activities”和“rainforests”可以定位到B段“Despite the importance of rainforests, deforestation practices continue. Though the term can apply to natural causes like forest fires, it’s commonly linked to human activities, like logging, agriculture and mining—all important for our economy”,故匹配段落为B段。

[A] New plants and animals then move into the area and begin to grow.[B] Just 2 percent of the sunlight goes through the many layers of leaves and branches above, so understory plant species have developed special traits to cope with low light levels.[C] On a smaller scale, large mammals, such as elephants, regularly destroy rain forest vegetation in the Congo River Basin in Africa.[D] An understory of shorter trees and a lacework of woody vines, or lianas, produce a forest of such complex internal architecture that many animals, including some sizable ones, rarely or never descend to the ground.[E] Less than one percent of the trees in the forest reside in the canopy and emergent layers.[F] Because more light penetrates the canopy, however, the vegetation of the understory and forest floor is better developed than in the tropics.[G] The rich, green canopy is teeming with life, and forest researchers have developed ingenious methods for accessing this mysterious ecosystem.

The Smokey Bear(护林熊) fire prevention program has resulted in a savings of $20 billion on all federal(联邦的), state and private forested land(私有林地). In 1941, 208,000 forest fires burned 30 million acres, while in 1981, fewer than 165,000 fires burned about three million acres. While forest usage has increased, the proportion(比例) of human-caused fires has remained stable; people still cause nine out of ten forest fires. But the biggest cause of fires is arson(纵火), accounting for(引起) 34 percent of forest fires in 1981.1. According to the passage, use of forested land has ____.A、stabilizedB、been privatizedC、decreasedD、risen2. According to the passage, in 1941 forest fires burned ____.A、less acres than in 1981B、3 million acresC、ten times as many acres as in 1981D、20 million acres more than in 19813. According to the passage, the number of human-caused fires ____.A、has remained the same proportionatelyB、has increasedC、is the same as the arson casesD、accounts for 34 per cent of forest fires4. According to the passage, which of the following statements is true?A、Nine out of ten fires are caused by arsonists.B、The Smokey Bear program has saved the nation a lot of money.C、There are more forest fires now than before.D、People do not use the forests as much as they did in the past.5. It may be inferred from the passage that ____.A、the majority of fires are caused by humansB、arson is increasing every yearC、more acres are destroyed by fire each yearD、fewer people are using the forests

Data mining is an(66)research field in database and artificial intelligence. In this paper, the data mining techniques are introduced broadly including its producing background, its application and its classification. The principal techniques used in the data mining are surveyed also, which include rule induction, decision(67), artificial(68)network, genetic algorithm, fuzzy technique, rough set and visualization technique. Association rule mining, classification rule mining, outlier mining and clustering method are discussed in detail. The research achievements in association rule, the shortcomings of association rule measure standards and its(69), the evaluation methods of classification rules are presented. Existing outlier mining approaches are introduced which include outlier mining approach based on statistics, distance-based outlier mining approach, data detection method for deviation, rule-based outlier mining approach and multi-strategy method. Finally, the applications of data mining to science research, financial investment, market, insurance, manufacturing industry and communication network management are introduced. The application(70)of data mining are described.A.intractableB.emergingC.easyD.scabrous

共用题干Ants as a Barometer of Ecological ChangeAt picnics,ants are pests.But they have their uses.In industries such as mining,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 ant—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._______(46) 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._______(47)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 recolonize the stripped land more quickly than others._______(48)Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recov-ery 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._______ (49)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. ______(50)_______(46)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.
