Batsandbirdslandindifferentways.【答案】（1）D（2）C（3）C（4）B【解析】【分析】本文是一篇议论文，作者用研究事实来证明蝙蝠在飞行及运动方式与鸟类完全不同。以前人们认为蝙蝠和鸟类在运动方面没有什么区别，但现在的研究证明蝙蝠的构造不同于鸟类，它们的翅膀由前肢和后肢组成，它们自我调节能力好，可迅速改变飞行方向，或完全逆行，这是鸟类不容易做到的，而且蝙蝠飞行的另一个有趣特征是蝙蝠倒立着降落的！这不同于那些降落在地上或树枝上的鸟。（1）考查主旨大意。根据第一段中的"Bothbatsandbirdshavemasteredtheskilloflanding,butthesetwotypesofflyersgoaboutitquitedifferently."提出了蝙蝠与鸟的降落方式及飞行的不同。第二段用研究证明过去认为蝙蝠和鸟类在飞行运动方面没有什么区别是错误的。尤其是"theyaremuchbetterattheabilitytoadjustthemselves:abatcanquicklychangeitsdirectionofflightorcompletelyreverseit,somethingabirdcannoteasilydo"可知蝙蝠与鸟的运动不同；第三段中的"Anotherinterestingcharacteristicofbatflightisthewayinwhichbatsland-upsidedown!Unlikebirdswhichtouchdownonthegroundorontreebranches,…"再一次说明了蝙蝠与鸟运动方式的不同。综上所述，可知，蝙蝠与鸟运动方式的不同是本文的主题。故选D。（2）考查推理判断。根据第二段中的"Inthepastitwasbelievedthat,intermsofflyingmechanics,therewaslittledifferencebetweenbatsandbirds.Thisbeliefwasbasedonlyonassumption,however,becauseforyearsnobodyhadactuallystudiedindetailhowbatsmovetheirwings…Thismakescoordinating(协调)theirlimbsmoredifficultforbatsand,asaresult,theyarenotverygoodatflyingoverlongerdistances."可推断出，过去人们认为蝙蝠与鸟在飞行运动方式与鸟没有区别，最近的研究发现，这是不正确的，故也是要纠正的，故选C。（3）考查代词指代。划线部分的上下文说"蝙蝠在自我调节的能力上要好得多：蝙蝠可以迅速改变飞行方向，或者完全与它（正飞行方向）相反的方向飞行，这是鸟不容易做到的。"由此可知，此处的"it"指的是飞行的方向。故选C。（4）考查推断判断。根据第三段中的"Anotherinterestingcharacteristicofbatflightisthewayinwhichbatsland-upsidedown!Unlikebirdswhichtouchdownonthegroundorontreebranches,batscanbeobservedflyingaroundandthensuddenlyhangingupsidedownfromanobjectoverhead.Onedownsidetothislandingroutineisthatthebatsoftenlandwithsomeforce,whichprobablycausespain."可知，蝙蝠飞行的另一个有趣特征是蝙蝠倒立着降落的方式！不同于那些降落在地上或树枝上的鸟，观察到蝙蝠可以四处飞行，然后突然倒挂在头顶的物体上。这种降落方式的一个缺点是蝙蝠经常用力降落，这可能会导致疼痛。因此蝙蝠与鸟不同，蝙蝠可以倒挂着。故选B。【点评】本题考点涉及推理判断，代词指代和主旨大意三个题型的考查，是一篇科研类阅读，要求考生根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。5．犇犇阅读理解

Energy,effortandresponse【答案】（1）C（2）D（3）D（4）B【解析】【分析】本文是一篇说明文，研究表明，老年人往往会记住生活中积极的事物，而不是消极的事物。十年前作者与生物学家罗伯特·特里弗斯合作研究身体是如何使用能量的，他们的发现解释了这一现象。（1）考查推理判断。根据第二段中的“Wehaveanenormousnumberofimmunecellscoursingthroughourbody,amomentarybreakfromproductionisfine.So,whenourbodyneedsextraenergy,oneoftheplacesitgoesisourimmunefunction.”可知我们的身体里有大量的免疫细胞，暂时停止运作是可以的。因此，当我们的身体需要额外的能量时，（我们的身体）会去找免疫系统。由此可以推断，免疫系统会暂时停止来为身体提供额外的能量。选C。（2）考查词义猜测。根据第三段中的"becomingmorefocusedonthepositivethingsinlifeinanefforttoenhancetheirimmunefunctioning."可知老人们更加关注生活中积极的事物，是为了增强他们的免疫功能。也就是说积极与免疫功能之间有关系，越积极，免疫功能越强，就能活得越久，所有选项中D项（乐观与寿命）之间最切题，故选D。（3）考查推理判断。根据最后一段中的"Asaresult,ourimmunesystemevolvedtoruninmaximumamountswhenwe'rehappy,buttoslowdowndramaticallywhenwe'renot."可知当我们快乐时，我们的免疫系统进化到最大程度，但是当我们不快乐时，免疫系统会减弱。由此推断，消极会消耗我们身体的能量，降低对疾病的抵抗力。选D。（4）考查主旨大意。作者开头提出老年人更关注积极的事情，后文提到积极的情绪会增强免疫系统，所以本文主要讲的是年龄，健康与积极的情绪之间的关系，选B。【点评】本题考点涉及推理判断，词义猜测和主旨大意三个题型的考查，是一篇科研类阅读，考生需要根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。7．阅读理解
