28、t解析：语法题。by和in都表示将来；但in表示时间段，如in five days；by表示时间点，如by Sunday。A.will find outB.has found outC.will be finding outD.will have found out解析：语法题。因句末有by then，因此必须用将来完成时，故选D。A.industrialB.industriousC.industrializedD.assiduous解析：词义辨析题。根据下文中的industries(工业)和technology(科技)的发展等等，能够推断这里用industrialized(工业化)最合适。A

29、.forcedB.expectedC.knownD.foretold解析：词义辨析题。句意：发达国家的产量预计增加5倍；B最合适。A.DevelopingB.DevelopedC.UnderdevelopedD.Undeveloped解析：逻辑关系题。前面已讲过advanced countries(发达国家)，相对应地接下来应该讲developing countries(发展中国家)。A.will tryB.will be tryingC.will have triedD.will have been tried解析：语法题。句意：发展中国家以公路、机场和发电站为支撑，将至少建立采掘工业，并将

30、尝试出口，以支付进口的食品和技术。可见，尝试出口是一种持续的过程，应该用进行时，故选B。A.backB.upC.fromD.down解析：词义辨析题。pay back偿还，报答；pay up全部付清；pay down付头款，用现金支付；没有词组pay from。根据“偿还进口的食物和技术”，选A。A.DoubtfulB.DoubtlessC.DoubtedD.Undoubted解析：词义辨析题。doubtful(形容词)可疑的，令人生疑的；doubtless(副词)无疑地，确定地；doubted(形容词)被怀疑的；undoubted(形容词)无疑的，确定的；很明显，本空应是一个副词，故选B。A

31、.suspectedB.suspectingC.unsuspectedD.unsuspecting解析：词义辨析题。suspected可疑的，有嫌疑的；suspecting可疑的，不可信的；unsuspected未意识到的，未知的；unsuspecting无疑心的，不怀疑的。句意：有未知副作用的新药和杀虫剂将会被发明。可知C适合。A.meansB.waysC.methodsD.information解析：词义辨析题。means方法，手段，工具；way方法，方式；method方法，办法；information信息。句意为新的运输工具或手段，means最贴切。A.excludeB.includeC

32、.affectD.invade解析：词义辨析题。exclude排除，排斥；include包含，包括；affect影响；invade侵扰，干扰；根据题意，invade表达得更形象。A.forB.atC.onD.in解析：语法题。in在将来时中表示时间段，如in five days；而on表示时间点，如on Sunday。因此，选A。A.sonicB.solarC.sunnyD.shining解析：词义辨析题。sonic boom是航天术语，意为“超音波爆声，音爆”。故选A。A.causeB.lay outC.produceD.spell解析：词义辨析题。cause引起，导致(一般指不好的事)；A

33、最贴切。A.muchB.littleC.moreD.less解析：语法题。与前文的more(比较级)相对应，应用。less(little的比较级)。A.possibilitiesB.attemptsC.awarenessD.suggestions解析：词义辨析题。make an attempt(试图，尝试)是固定搭配，因此结合题意以及下面的“made”可知，B是最佳选项。A.ownersB.childrenC.furnitureD.babies解析：词义辨析题。owner所有者，业主，主人；children儿童，孩子；furniture家具，设备；baby婴儿；根据题意，应选owner，即嘴的

34、主人；其他都不合适。A.fallingB.fallenC.fellingD.felled解析：词义辨析题。falling正在倒下的；fallen(fall的过去分词)已经倒下的；felling正在砍伐的；felled伐倒的。因为下文“将要听到回声”，所以选A最合适。A.existentB.existC.existenceD.extant解析：惯用法题。come into existence(开始存在)为固定搭配。The homeless make up a growing percentage of Americas population. 21 homelessness has reache

35、d such proportions that local governments cant possibly 22 . To help homeless people 23 independence, the federal government must support job training programs, 24 the minimum wage, and fund more low-cost housing. 25 everyone agrees on the number of Americans who are homeless. Estimates 26 anywhere

Part of the problem is that many homeless adults are addicted to alcohol or

38、drugs. And a significant number of the homeless have serious mental disorders. Many others 34 not addicted or mentally ill, simply lack the everyday 35 skills needed to turn their lives 36 .

39、address the many needs of the homeless. 38 Edward Zlotkowski, director of community service at Bentley College in Massachusetts, 39 it, There has to be 40 of programs. Whats needed is a package deal.（分数：30.00）A.IndeedB.LikewiseC.ThereforeD.Furthermore解析：关联词题。根据本段首句可知，在美国有越来越多的无家可归者，空格后说到“无家可归的人所占比例如

40、此之大，以至于地方政府”，下文是对前文的解说和强调。只有A项Indeed(的确，确实)与题意相符，所以本题应选A项。A.standB.copeC.approveD.retain解析：语义逻辑题，兼考查词义辨析。根据原文可知由于无家可归的人所占比例过大，导致地方政府不能选项B中的cope有“对付，处理，对抗，与困难作斗争并且克服它们”的含义，与题意相符，所以本题选B项。A.inB.forC.withD.toward解析：词义逻辑题。原文要表达的意思是“帮助无家可归者达到独立”。选项D中的toward有“达成，意在达到，以为目标”的意思，故本题应选D项。A.raiseB.addC.takeD.ke

41、ep解析：语义逻辑题，兼考查词义辨析。原文提到了“支持就业培训项目；最低工资；资助建设更多低价住房”等等一系列减少无家可归者数量的政府措施，联系上下文可知，此处填“增加”符合语义逻辑，由此排除C和D，而选项B中add的宾语一般是具体数字，也可排除，所以本题应选A项raise。A.GenerallyB.AlmostC.HardlyD.Not解析：语义逻辑题。联系下文中提到的“对无家可归者数量的估计从60万到300万不等”推断可知本句表达的意思是每个人的意见都不一致，所以本题应选D。A.coverB.changeC.rangeD.differ解析：固定搭配题，兼考查上下文逻辑。range from

42、.to.是固定搭配，表示“自至不等”，所以本题答案为C。A.Now thatB.AlthoughC.ProvidedD.Except that解析：关联词题。由逗号前后的两个分句的动词vary和agree可以看出空白处前后构成明显的转折让步关系，四个选项中只有Although符合题意，所以本题应选B项。A.inflatingB.expandingC.increasingD.extending解析：词义辨析题，兼考查语义逻辑。根据文章第一句可知“无家可归者在美国人口中所占的比例越来越大(growing percentage)”，本空格要与growing构成呼应，表示人口数量的增长用increas

43、ing，所以本题答案为C。A.predictsB.displaysC.provesD.discovers解析：语义逻辑题，兼考查词义辨析。下文提到“无家可归者的人数在本年代末将会达到近1900万”，这是对未来情况的预测，由此可见，选项A项predicts“预计、预测”符合原文逻辑关系，所以本题应选A项。A.assistB.trackC.sustainD.dismiss解析：语义逻辑题，兼考查词义辨析。联系下文可知，本段讲的主要是如何全面地改变这批无家可归者的生活状况，由此推断可知，前文要表达的意思是“想办法帮助这些越来越多的无家可归者的任务变得越来越艰巨”，选项中虽然没有help一词，但是A项

44、中的assist与help意思相近，所以本题答案为A。A.HenceB.ButC.EvenD.Only解析：关系连词题。根据主句中的still一词可知，空白出前后构成让步的逻辑关系，所以本题应选C项。A.lodgingB.shelterC.dwellingD.house解析：词义辨析题。选项给出的四个词中只shelter。一词有“避难所，收容所(为无家可归的人提供暂时栖息场所的机构)”的意思，由此可见，选项B最符合题意，所以本题答案为B。A.searchingB.strollingC.crowdingD.wandering解析：词义辨析题，兼考查语义逻辑。原句的意思是“还是会有很多人每天大部分

45、时间流落街头”，由此可以排除A和C；而选项B中的strolling表示“悠闲地散步”，与原文不符，也可排除，而选项D中的wander意为“漫无目的地游荡，流浪”，符合题意，所以本题应选D。A.whenB.onceC.whileD.whereas解析：关联词题。联系上下文可知，空白处前后提到的“喝酒吸毒。并且患有严重的精神错乱疾病的无家可归者”与“不酗酒不吸毒，精神也正常的无家可归者”形成并列关系，四个选项中只有while表示并列关系，所以本题应选C。A.lifeB.existenceC.survivalD.maintenance解析：词义辨析题，兼考查语义逻辑。区分life skills(生活技能)和survival skills(生存技能)是解答本题的关键。既然是正常的“无家可归者”，根据常识可知他们缺乏的是“生存能力”，所以本题应选C。A.aroundB.overC.onD.up解析：语义逻辑题，兼考查固定搭配。原句的意思是“他们缺乏生活技能来改变自己的生活”，turn a
