【答案】

（1）B

（2）B

（3）D

（4）A

【解析】【分析】本文是一篇说明文，科学家通过改变植物的基因，加快光合作用的速度，使植物叶子生长迅速，从而提高植物产量。

（1）考查细节理解。

根据第一段中的“scientistshavefoundawaytohackaplant'sgenesinordertomakeitusesunlightmorequickly.Someday,theresultscouldincreasetheamountoffoodproducedaroundtheworld.”可知，科学家发现改变植物基因会使植物的光合作用速度加快，将来会增加全球植物的产量。

故选B。

（2）考查推理判断。

根据第四段中的“Hecomparedaplant'sprotectivesystemtolight-adjustingglasses.Whenapersonwearstheglassesoutsideduringtheday,thelenses（镜片）darkenandlightendependingonhowsunnyitis.Plantsdothesamething,hesaid.Butinplantstheadjustmentcantakeanywherefrom10minutestoanhour.”可知，作者提到镜片是为了说明植物的保护系统的工作原理与镜片相同。

故选B。

（3）考查细节理解。

根据最后一段中的“Buttheythinkthegeneticchangeswillproducethesameresultsincornandrice.”但是他们认为基因的改变将在玉米和水稻中产生相同的结果。

可知选D。

（4）考查主旨大意，根据文章内容可知，科学家改变植物的基因，加快光合作用的速度，使植物叶子生长迅速，从而提高植物产量。

故选A。

【点评】本题考点涉及细节理解，推理判断和主旨大意三个题型的考查，是一篇科研类阅读，要求考生在捕捉细节信息的基础上，进一步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。

【答案】

（1）B

（2）C

（3）D

（4）D

【解析】【分析】本文是一篇说明文，登山者报告说看到一只长颈鹅翱翔在珠穆朗玛峰的顶峰，为了确认其真实性，研究人员养了18只这种鹅，在大型风洞中训练它们飞行。

结果发现这种鹅可以在氧气极低的情况下飞行，但停留时间只有几分钟，因此能否飞过珠峰尚不明确。

（1）考查推理判断。

根据第一段中的"In1953,amountainclimberreportedseeingabar-headedgoosesoaroverthepeakofMountEverest.Itwasthoughtimpossible."报道说，一名登山者看到一只斑头鹅飞过珠穆朗玛峰。

人们认为这是不可能的；以及"Nowresearcherswhoraised19ofthegeese-namedfortheblackstripesonthebacksoftheirheads-haveshownthebirdsreallyflysohigh."现在研究人员饲养了这种鹅，他们发现这些鹅真的飞得很高。

再根据最后一段中的"Soit'snotclearwhethertheseadaptationsalonearewhatmakeitpossibletoflythe8hoursittakestoclimboverMountEverest.ButthosefewminutesshowedthesegeesereallycouldflyoverthetopofMountEverest."但是否能让这种鹅飞8小时爬上珠穆朗玛峰尚不清楚。

由此可推断出研究人员饲养这种鹅是为了证实这种鹅是否能飞过珠峰。

故选B。

（2）考查推理判断。

根据第四段中的"Thewindtunnelexperimentsshowedthatwhentheconcentrationofoxygen...thegeese'sheartrateandfrequencyofwingbeatsremainedthesameevenastheirmetabolicratedropped....theresearchersreporttodayinelife.Thiscoolinglikelyhelpscomp"可知风洞实验表明，当氧气浓度最低时，鹅的心率和翅膀搏动频率保持不变，即使它们的新陈代谢率下降。

研究人员今天在《伊利费》杂志上报道说，...这种降温可能有助于补偿空气的稀薄；第五段中的"Althoughwelltrained,thebirdswereonlywillingtostayintheairafewminutes-orless..."尽管训练有素，但这些鸟只愿意在空中呆上几分钟。

这两处综合推断出，鹅可以在最低浓度的氧气中生存。

故选C。

（3）考查推理判断。

根据最后一段中的"Soit'snotclearwhethertheseadaptationsalonearewhatmakeitpossibletoflythe8hoursittakestoclimboverMountEverest."可知，目前尚不清楚的是，只有这些适应性变化能否可以飞行8小时爬上珠穆朗玛峰。

故选D。

（4）考查推理判断。

第一段中提到登山者报告说看到一只长颈鹅翱翔在珠穆朗玛峰的顶峰。

为了证实是否可能，研究人员养了18只这种鹅，并在大型风洞中训练它们飞行。

结果发现这种鹅可以在氧气极低的情况下飞行，但停留时间只有几分钟，因此能否飞过珠峰尚不明确。

由此可知本文属于科普文章。

故选D。

【点评】本题考点涉及推理判断题型的考查，是一篇科研类阅读，要求考生根据上下文进行分逻辑推理，从而选出正确答案。
