6—10BACAB11—15DBABB

16—20CBACD解析：1.细节题。根据第1段中的Butwhatisuniqueaboutthisshoeiswhereitwasfound.ItwasdiscoveredontheCheckoutPass,thefamoustrail…可推知此题答案为B。2.细节题。根据第2段最后一句Unpreparedforsuchadangerousjourney可推知此题答案为D。3.推断题。根据第2段最后一句及第3段第1句可推知此题答案为A。4.细节题。根据文章最后一句可推知此题答案为C。5.推断题。根据Charles所说的Saying‘no’toothersmeansyouaresaying‘yes’toyourself(否定他人就意味着肯定自己)可推知此题答案为D。6.推断题。根据SusieWatson所说的Iwouldratherhavesomeonegivemealoving‘no’(我倒愿意听一声有爱意的否定)可推知此题答案为B。7.推断题。对文章倒数第5段最后一句Myadviceistosay‘yes’onlyifyoudon’tmean‘no’.反过来理解：只有当你不肯定的时候说“不”，可推知此题答案为A。8.推断题。从文章最后一段Charles所说的Don’tgotoextremes.Don’tfindyourselfsaying‘no’toeverything可知，不然的话就会遇到麻烦，故此题答案为C。9.细节题。根据AcharacteristicofAmericanculturethathasbecomealmostatraditionistorespecttheself-made

我们可以了解到，“崇尚自我奋斗”是美国文化的特点。10.推断题。根据Thisattitudetowardmanual(体力的)laborisnowstillseeninmanyaspectsofAmericanlife.(在美国生活的方方面面，尊重体力劳动态度的现象仍然随处可见)，可以推断女主人亲自下厨，是因为她以能做这样的体力活而自豪。11.词义猜测题。waitontable意为“服务顾客”，注意其后的washingdishes也有一定的暗示意义，故答案为D。12.主旨题。纵观全文，文章主要讲了美国崇尚自我奋斗，尊重体力劳动的文化习惯。故答案为B。13.细节题。根据文章星期五活动安排的第1句JAZZwiththeMikeThomasJazzBandatTheDerbyArms.可推知此题答案为A。14.细节题。根据星期六活动安排最后一句theelectricaccordionTel:789—4536可推知此题答案为B。15.细节题。根据星期六活动安排第4行FAMILYnightout?Jointhesing-alongatTheBlackHorse.可推知此题答案为B。16.细节题。根据星期天活动安排最后3段可知FOLKMUSIC在TheDerbyArms演出，而TheDerbyArms的地址是UpperRichmondRoadWest.EastSheen，与HeavyMusic在同一条街上。故选C。17.语义理解题。从第2段内容可知，“诺亚方舟”工程的目标是把濒临灭绝的动物的蛋(卵)、胚胎、精液和DNA储存在液体氮中，如果某一种动物濒临灭绝时，将来可以重现这一动物。18.细节题。从第6段第1句话Thenucleartransfer(核子移植)ofonespeciestoanotherisnoteasy,andthelackofavailable(capableofbeingused)pandaeggscouldbeamajorproblem

可以做出正确判断。19.主旨题。从文章内容来看，无论是中国还是世界克隆熊猫还没有成功，所以排除A、B项；D项内容明显与文章内容不符，故排除。所以“探索克隆熊猫的可能性”应该是这篇文章的标题。20.判断题。此题B项的干扰性较强，但由于它没有说明是Chinesescientists，所以应排除。A、C项明显与原文不符。根据文章第3段第1句可知答案非D莫属。5.Hissonwasputin_____prison.Hewentto_____prisontoseehimonceamonth.答案：C6.Itwasjustintheroom_____hewasborn_____hedied.A．where,whichB．that,thatC．where,thatD．which,that答案：C，解析：为强调句型，被强调成分是intheroom，wherehewasborn为修饰theroom的定语从句。7.IwishtothankProfessorSmith,without_______helpIwouldneverhavegotthisfar.A．whoB．whoseC．whomD．which答案：B解析：考查定语从句。withoutwhosehelp="and"withouthishelp。whose引导的是非限制性定语从句，在句中作“help”的定语，其先行词为“ProfessorSmith”。句意：我真得感谢史密斯教授。如果没有他的帮助，我就永远不会（在学术上）走得这么远的。8.I’mgoingtoEuropeonvacationtogetherwithJohnifI_______findthemoney.A．canB．mightC．wouldD．need答案：A解析：此处考查了can的本意“能”，表示“能力”。句意：我要和John一起去欧洲度假，如果我能找到钱。【考点定位】考查情态动词的用法。9.Itisbelievedthatanewkindofdrug_____bythescientistsandtheyarehopefulthattheywillsucceedinacoupleofmonths.

BCBAB解析：文章大意：这是一篇科普文，分析全球变暖的真正原因，到底是因为人类生活排放的二氧化碳还是因为太阳活动，今天的天气状况并没有印证若干年前的科学预测。66.B细节理解题。由文章第一段可知大量二氧化碳集中在一起，会使地球表面的温度升高。因为二氧化碳的作用就象单向的镜子或者温室的玻璃屋顶一样只允许阳光进来，而里面的热却无法散去。67．C主旨大意题。文章第一至第四段解释二氧化碳对全球气候的影响，而第五、六段又怀疑二氧化碳的作用，分析太阳活动对全球变暖的影响。由此看来，文章的目的是解释影响天气的原因。68．B细节理解题。文章第五段提出北半球消耗燃料多，排放的二氧化碳量大，按道理北半球气候应升高但实际反而下降，什么原因？第六段从太阳活动解释了上述疑问：可能部分是由于太阳能量释放的不同。69．A细节理解题。由最后一段第二句”TheproblemisthatthemodelsarepredictingthattheworldshouldbeenteringanewIceAgeanditisnot”可以推测科学家认为地球气候应变冷，而入新的冰河时期。70．B推理判断题。如果新的冰河时期推迟的假设正确，可能是因为地球表层的二氧化碳起的保温作用。11.Theboywantedtoridehisbicycleinthestreet,buthismothertoldhim______.答案：B12.ToreadTolstoyand____tothenineteenthcenturyRussianliteraturearetwoexcellentreasonsfortaking

A.

earned答案：D解析：：本句考查现在完成时用法中“过去发生的动作对现在造成的结果和影响”这一用途，强调nothavinggoneabroad对现在的影响。第二个说话人表达的意思是：虽然我现在没有钱像出了国那样挣那么多，但是我很欣慰为祖国做出了贡献。【标签】动词时态16.“Childrenwhoeatlesssaltanddrinkfewersugar-sweetenedsoftdrinksmaysignificantlylowertheirrisksofobesity,”researchersrecentlyreportedinthejournalHypertension.
