3.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

    analytical data mining(名词解释)


    参考答案:分析性的数据挖掘

  • 第2题:

    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.DESTROY—INIT—LOAD

    B.DESTROY—LOAD—INIT

    C.DNT—DESTROY—LOAD

    D.LOAD—INIT一DESTROY


    正确答案:D

    此处表示“有毒气体的释放”,表示气体的释放应用"release"。 paste糨糊;consumption 消费;release释放;elimination消除,根除。
    地下煤的燃烧是一种全球性的灾难,令人惊奇的是却很少有人了解,这里表示的是一种惊讶。happily愉快地;surprisingly惊人地,出人意料地;traditionally传统地;fashionably时髦地。
    在有阳光和氧气的情况下,产生的热量会引起自燃,可见煤产生的热量并没有消失。 disappear消失;exchange交换;regenerate再生;transfer转换,转变。
    此处表示:这样的火灾在中国每年消耗的煤多达2亿吨。most大多数,大部分;some一些,某些;such这种的,这样的;many许多,很多。
    in comparison表示“与……相比”,用在这里表示中国发生自燃的煤量与美国经济消耗的煤量的比较。case案件,情况;time时间,时代;comparison比较;turn转动,旋转。
    空格后的analysis与空格前的先行词Stracher是所有关系,因此用whose来引导这个定语从句,并在从句中作主语。which哪一个,一般用来引导先行词为物的定语从句;who谁,常用来引导先行词为人的定语从句,并在从句中作主语;what什么,常用来引导疑问句或名词性从句。
    这句话的意思是:地下的煤一旦燃烧,火焰将会持续几十年,甚至几百年。因此用连词 once。 yet然而;unless除非;once一旦;although尽管,虽然。
    volume表示the amount of sth.,意思是“量,额”,用在这里表明有毒气体、温室气体以及黑色颗粒的量很大。data数据;figure数字;volume量,分量;image影像,形象。

    根据后文的how much可知,这里指的是对产生的二氧化碳的量的评估。experiment实验;estimate评估;gather收集,聚集;illustrate说明,解释。
    Gary Colaizzi提出的是一种控制这些火焰的方法,因此用method来表示。cause原因,动机;treatment治疗,疗法;rule规则,规定;method方法,方式。
    切断氧气的供应,应该用cut off来表示。take up占据;cut off切除,切断;back up支持; run out用完,耗尽。

    C.INIT→DESTROY→LOAD

    D.LOAD→INIT→DESTROY


    正确答案:D
    解析:INIT事件在对象建立时引发。在表单对象的INIT事件引发之前,将先引发它所包含的控件对象的INIT事件;LOAD事件在表单对象建立之前引发,即运行表单时,先引发表单的LOAD事件,再引发表单的INIT事件;DESTROY事件在对象释放时引发。

    C.start→init→destroy→stop

    D.start→init→stop→destroy


    正确答案:B
    解析:该题考查对Java Applet生命周期的几个函数执行顺序的理解。Applet生命周期是指从Applet下载到浏览器,到用户退出浏览器,终止Applet运行的过程。Applet运行时,首先由浏览器调用init()方法,然后调用start()方法,使Applet成为激活状态,当Applet被覆盖时,调用stop()停止线程,最后关闭浏览器调用 deserog()。故本题答案是B。

    Ants as a Barometer of Ecological Change
    At 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.

    答案:F
    解析:
    空前一句“Only certain species , for instance , will continue to thrive at a forest site that has been cleared of trees”讲到某些特定物种在被砍光树木的森林里还能够继续存活,空后一句“still others will move in and take up residence”讲到自然会有其他生物迁入并定居下来,F项“其他种类将会因为缺乏食物而灭绝”与上下文联系紧密,符合语境。
    空后一句“scientists can determine how ‘stressed ' the land is”讲到科学家们之所以利用蚂蚁是因为它们很常见而且种类繁多,在此之前应该说明怎么样利用蚂蚁,D项 “科学家们的观察是通过对蚂蚁的分类、数目的确定以及与前期调查结果的对比分析来进行的”符合语境。
    空前一句讲到在一些矿井地带的recolonize(复原)过程中,会有一些蚂蚁的物种比其他物种更快地重新在植被破坏的土地上安家,A项“这样可以帮助科学家们测定生态恢复的速度和进程”与上文联系紧密,并且A项中的“the ecological recovery”与本段首句中的“are being restored”相照应,故选A。
    空前一句“that governments worldwide accept their results when assessing the environ-mental impact of mining and tree harvesting”讲到世界各国政府都承认了通过蚂蚁而得出的关于估测采矿和伐林对环境带来的影响的结果,而第七段第一句则问道:为什么不用呢?B项“然而在另外一些行业中,比如农业和房地产开发业,用蚂蚁调查的方法并没有被广泛地采用”与下文联系紧密,起承上启下作用,符合语境。
    空前一句“many companies can't afford the expense or the laboratory time needed to sift results for a comprehensive survey”讲到很多国家不能付出高额的费用,研究蚂蚁的专家稀少,故C项“雇佣他们花费巨大”与上文联系紧密,符合语境。

    【录音原文】
    Because soot promotes the melting of snow and ice, it may exacerbate the problem of rising seas. The good news is that reducing the amount of soot in the air by installing exhaust filters on diesel trucks and buses and better managing forest fires is probably easier than getting Americans to give up SUVs. Fires are the source of about half the world’s soot.
