【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。

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。

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。
