【答案】32.A33.D34.B35.A
【解析】本文是一篇科普说明文。
文章讲述了新旧电子设备的差别,旧电子设备耗能高,不环保。
所以作者主张使用新电子设备。
33.细节理解题。
根据文章第二段中的Tofigureouthowmuchpowerthesedevicesareusing,CallieBabbittandhercolleaguesattheRochesterInstituteofTechnologyinNewYorktrackedtheenvironmentalcostsforeachproductthroughoutitslife可知,Babbitt’steam研究的目的是弄清楚这些设备用了多少电。
故选D。
34.细节理解题。
根据文章最后一段中的Theyfoundthatmoreon-demandentertainmentviewingontabletsinsteadofTVsanddesktopcomputerscouldcutenergyconsumptionby44%.可知,平板电脑是耗能最少的电子设备,可以降低44%的耗能。
故选B。
35.推理判断题。
根据文章的整体内容可知,因为旧的电子设备耗能高,不环保。
所以作者建议停止使用旧的电子设备。
故选A。
点睛:
熟悉比较句型是彻底理解本文的关键,也是解题的关键。
本文中的比较句型:
1.That’sbadnewsfortheenvironment–andourwallets–astheseoutdateddevicesconsumemuchmoreenergythanthenewsonesthatdothesamethings
做同样的事,旧的过时的装置比新装置消耗更多能源,对环境有害,浪费钱财。
2.AccordingtotheanalysisofBabbitt’steam,olddesktopmonitorsandboxTVswithcathoderaytubesaretheworstdeviceswiththeirenergyconsumptionandcontributiontogreenhousegasemissions(排放)morethandoublingduringthe1992to2007window.
根据Babbitt团队的分析,旧的桌面监视器和阴极射线管箱式电视机是最差的电子设备,它们的耗能和温室气体的排放是1992到2007window的两倍还多。
3.Theyfoundthatmoreon-demandentertainmentviewingontabletsinsteadofTVsanddesktopcomputerscouldcutenergyconsumptionby44%.他们发现在平板电脑上看的随需变化的娱乐节目比在电视和电脑上看耗能减少了44%。

【答案】24.D25.A26.D27.A
【解析】文章分析了几种购物袋的使用情况,塑料袋造成了环境问题,尽管纸袋容易回收,但生产和运输需要更多的能源,希望消费者使用耐用可重复使用的袋子。
24.细节理解题。
根据第一段oneof
sjobsisdefendinganindustrybehindtheplasticshoppingbags.和第二段plastic-bagmakersarehiringscientistslike
makethecasethattheirproductsarenotasbadfortheplanetasmostpeopleassume.可知塑料袋生产商雇用StevenStein是为了证明他们的产品并不像大多数人想象的那样对地球有害,是对塑料袋被禁用的解释和争论。
25.词义猜测题。
上文介绍在许多美国大城市塑料袋被禁用,看到这种现状,塑料袋生产商雇用StevenStein等科学家是为了证明他们的产品并不像大多数人想象的那样对地球有害。
headwinds“逆风”,此处指塑料袋被禁用的现状,即Bansonplasticbags,故选A。
26.细节理解题。
根据第四段However,longer-lastingreusablebagsoftenrequiremoreenergy
make.可知塑料袋生产商认为生产耐用且能重复使用的袋子需要更多的能量,故选D。
27.标题归纳题。
文章讲述了使用塑料袋造成的环境问题,纸袋容易回收,但生产和运输需要更多的能源,希望消费者使用耐用可重复使用的袋子。
对这三种方式进行了对比,Plastic,PaperorNeither既能概括全文,又能吸引读者,最适合作为标题。
【点睛】
概括主旨的方法是:
先看首尾或各段开头再看全文找主题句,若无明显主题句,就通过关键词句来概括(如议论文中寻找表达作者观点态度的词句,要看懂全文的主要内容,明白了主要内容就能准确概括文章标题。
小题4要求概括标题,本文讲述了使用塑料袋造成的环境问题,纸袋容易回收,但生产和运输需要更多的能源,希望消费者使用耐用可重复使用的袋子。
对这三种方式进行了对比,Plastic,PaperorNeither既能概括全文,又能吸引读者,适合作为标题。
