4.D本文是一篇科普说明文。文章主要介绍了一种可以给手机充电的海滩垫子。【1题详解】推理推断题。开头第一段举在海滩度假无法给手机充电的事例,主要为了吸引读者对该话题的爱好。故选B。【2题详解】细微环节理解题。依据文章其次段Thematalsohastherefrigerationequipmentthatcanhelpkeepdrinkscool,justliketherefrigerator.可知,Beachill还具有冰箱一些功能。故选C。【3题详解】推理推断题。依据文章最终一段内容及第一句Somepeoplelikethematbecauseitislightweightandeasy-to-carry.可以推想,举RitaMathieu的事例是为了证明Beachill的运用便利。故选B。【4题详解】主旨大意题。依据全文内容可知,文章主要介绍了一种可以给手机充电的海滩垫子。故选D。B【答案解析】1.A
2.B
3.C
4.D【分析】这是一篇说明文。科学家指责温室气体是全球气候改变的主要缘由。文章介绍了一组探讨人员宣布的一项胜利的试验,这个试验将二氧化碳转化为有用的液体燃料。【1题详解】细微环节理解题。依据第一段第一句Scientistsblamegreenhousegasesforbeingamajorcauseofclimatechangearoundtheworld.“科学家指责温室气体是全球气候改变的主要缘由。”由此可知,“温室气体”是气候改变的主要缘由。故选A。【2题详解】细微环节理解题。依据其次段中Formicacidisasubstance(物质)foundinantsandsomeotherinsects,aswellasinmanyplants.“蚁酸是一种存在于蚂蚁和其他昆虫以及很多植物中的物质。”由此可知,蚁酸可以在蚂蚁身上找到。故选B。【3题详解】推理推断题。依据最终一段第一句Wangsaidthereactorcouldeasilybeusedtoproduceotherhigh-valueproducts,includingalcohol-basedfuels.“王说,该反应堆可以很简单地用于生产其他高价值产品,包括酒精燃料。”由此可知,王对自己的探讨持“乐观的”看法。故选C。【4题详解】推理推断题。依据最终一段中Theresearchersnotedthatthetechnologycouldalsobeabighelpinsolvinganothermajorenergyproblem—howtostorelargeamountsofpowerinsmallplaces.“探讨人员指出,这项技术还可以帮助解决另一个主要的能源问题——如何在小地方储存大量电力。”由此可知,这是科学探讨,这样的文章不行能在旅游杂志、体育杂志和音乐杂志上读到,所以最有可能在“科学杂志”上读到。故选D。【点睛】推理推断题要求在理解原文表面文字信息的基础上,做出肯定的推理推断,从而得到文章的隐含意义和深层意义。推理推断题所涉及的内容可能是文中的某一句话,也可能是某几句话,所以,推理题的答案只能是依据原文表面文字信息一步推出的答案:即对原文某一句话或某几句话所作的同义改写或综合。推理推断题的题干中通常含infer,suggest,imply,conclude
indicate等标记性词语。本题第3小题,依据最终一段第一句Wangsaidthereactorcouldeasilybeusedtoproduceotherhigh-valueproducts,includingalcohol-basedfuels.“王说,该反应堆可以很简单地用于生产其他高价值产品,包括酒精燃料。”由此可知,王对自己的探讨持“乐观的”看法。故选C。C【答案解析】1.C
2.A
3.B
4.D【分析】这是一篇说明文。文章主要说明白科学家对气候改变问题的探究已经有近200年的历史了,文章介绍了“温室气体”和“温室效应”的发觉,以及温室效应发觉者SvanteArrhenius对温室效应的看法。到20世纪50年头末,美国科学家始终在为气候改变的长期后果敲响警钟。气候改变探讨已经取得了长足的进步。【1题详解】词义揣测题。依据上文Fourierconcludedthattheatmospheremustberesponsibleforcontainingtheheatabsorbedfromthesunanddescribed可知,Fourier得出结论,大气必需负责汲取太阳汲取的热量,并将它(大气)描述为一个有玻璃盖的盒子:当光线穿过玻璃时,由于盖住了热量,盒子内部变得更热。可知it指的是“大气”,故选C。【2题详解】推理推断题。依据第四段中Atalecturelaterthatyear,Arrheniusnotedthatcreaturesofawarmerearth“mightliveunderamilderskyandinlessbarrensurroundings”.可知,在那年晚些时候的一次演讲中,Arrhenius指出,地球变暖的生物“可能生活在更温柔的天空下,也可能生活在不那么贫瘠的环境中”。由此可推知,Arrhenius认为看待温室效应对地球上的生物是有益的。故选A。【3题详解】推理推断题。依据最终一段Fourierfirstdescribedthegreenhouseeffect—still,maybeArrheniusshouldhavebeenmorecarefulofwhathewishedfor.可知,自从Fourier第一次描述了温室效应以来,气候改变探讨已经取得了长足的进步——尽管如此,或许Arrhenius应当更加当心他所希望的。由此可推知,作者对Arrhenius的愿望持反对看法。故选B。【4题详解】主旨大意
