D.

Theplatesolutiontoeatingandenvironmentalproblem.【答案】（1）A（2）C（3）D（4）D【解析】【分析】本文是一篇说明文，介绍了饮食和环境的问题，并且提出了相应的解决方法。（1）考查推理判断。根据第二段中的“Theirproductsareenvironmentally-friendly,100%biodegradableandcanbeusedforalltypesofcateringandhomeuse.Andthey'remadefromanaturalplant.Afteruse,theycanbefedtoanimalsorlefttodegradenaturally.”可知，“昂贵”不是edibleplates的优势。故选A。（2）考查细节理解。根据第三段中的“Theyalsohavearangeofcutlery（餐具）madefromcornandpotatostarch（淀粉）．”可知，玉米和马铃薯淀粉可用于制作餐具。故选C。（3）考查代词指代。根据第三段中的“Wastefromplasticcausesalotofdamagetotheenvironment,aswellascostinggovernmentsmillionsmwastemanagement.Plasticbagsoftenendupinlandfillsitesoronthestreet.Andtheburningofplasticwastecausestoxicgasesthatpollutetheair.Inresponsetothis,governmentsaroundtheworldareintroducingtoughrecyclingregulations.”塑料垃圾对环境造成了很大的破坏，同时也给政府带来了数百万的垃圾管理。塑料袋经常会出现在垃圾填埋场或街道上。而燃烧的塑料垃圾会导致有毒气体污染空气。作为对此的回应，世界各国政府正在出台严格的回收法规。由此可知this指的是“塑料垃圾对环境造成的破坏。”故选D。（4）考查主旨大意。根据第一段中的“Whenwasthelasttimeyouusedplasticplates?Nexttime,whynottrysomeedibleones?You'llhelptheenvironmentandyourguestswon'tgohungry."可知，本文讲述的是饮食和环境问题的解决方案。故选D。【点评】本题考点涉及细节理解，推理判断，代词指代和主旨大意四个题型的考查，是一篇科普类阅读，考生需要准确掌握细节信息，同时根据上下文进行逻辑推理，概括归纳，从而选出正确答案。2．阅读理解

D.

WhentheoldestdogwasfoundintheAmericas.【答案】（1）C（2）A（3）B（4）A【解析】【分析】本文是一篇说明文，介绍了大概一万年以前就在北美成为人类伙伴的狗的种类。（1）考查细节理解。根据第二段中的“AthirddogfromanotherIllinoissitecalledStilwellIIwasolderstill,at10,190yearsold.ThatmakesittheoldestknowndomesticateddogintheAmericas.”可知，美洲最古老的家犬有10,190年。故选C。（2）考查词义猜测。根据第二段中的“Theteamconcludedthatallthreedogsweredomesticatedastheyskeletonswerecompleteandunskinned,andsohadn'tbeenbutcheredforfood.Theyhadalsobeencarefullyburied,evidencetheywerevaluedbytheirowners.”研究小组得出的结论是，这三种狗都是被驯化的，因为它们的骨骼是完整的，没有皮肤的，所以没有被宰杀作为食物。他们也被仔细地埋葬了，证据表明他们是被主人重视的。关键词buried，可知划线词的意思是“杀死”，故选A。（3）考查推理判断。根据第二段中的“ItisunclearwhyittooksolongfortamedogstoarriveintheAmericas,giventhattheyweredomesticatedatleast14,000yearsagoinEurasia.”可知，对到达美洲的驯服的狗态度是不确定。故选B。（4）考查主旨大意。根据第一段中的“DogswerelivingascompanionstotheearlysettlersofNorthAmericaover10,000yearsago.TheoldestdomesticdogsintheAmericaswerethoughttobearound9500yearsold.”可知，美洲有最早的家犬。故选A。【点评】本题考点涉及细节理解，词义猜测，推理判断和主旨大意四个题型的考查，是一篇科普类阅读，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。3．阅读理解

D.

Flesh-eatingcreatures.【答案】（1）A（2）B（3）C【解析】【分析】本文是一篇说明文，许多科学家认为，我们正经历着地球史上第六次大规模物种灭绝，主要原因是人类的过度捕猎、过度捕捞和人类栖息地的丧失。但是，各个科学家对过去物种灭绝原因有着不同的看法，即便是最近的一次小规模物种灭绝——大型动物灭绝，有关的灭绝原因，科学家仍在争论。(1)考查细节理解。第三段提到大规模物种灭绝是在arelativelyshortperiodoftime，所以B错误；最后一段提到大型动物的灭绝发生在theendofthePleistocene，而第六次大规模物种灭绝是当下正在发生的，所以C错误；根据第三段中的＂Theycallthiscurrentepisodethesixthmassextinction——alarge,globaldeclineinawidevarietyofspeciesoverarelativelyshortperiodoftime.Andtheytendtoagreethathumansarethemaincause.＂可知，科学家认为人类是第六次大规模物种灭绝的主要原因，没有不同意见，因此D错误，因此选A。(2)考查推理判断。根据第一段中的“Theremightbeasmanyas10millionspeciesofcomplexlifeonthisplanettoday”，以及第四段中的＂By2100,itisexpectedthathumanswillhavecausedtheextinctionofuptohalfoftheworld'scurrentspecies.＂可知，到22世纪，地球还会有目前物种的1/2会灭绝，也就是10million的半，即fivemillion，因此选B。(3)考查词义猜测。根据最后一段中的＂becausemanyofthespeciesitclaimedwereparticularlylargeanimals,weighingmorethan97lb(44kg).＂可推知＂megafaunal＂应为大型动物，因此选C。【点评】本题考点涉及细节理解，词义猜测和推理判断三个题型的考查，是一篇科普类阅读，考生需要准确捕捉细节信息，并根据上下文进行逻辑推理，选出正确答案。7．阅读理解
