9、据第一段最后一句可知,继续使用过时的装置对环境和我们的钱包都不是好消息,因为它们与新装置相比,做相同的事情会消耗更多的能源。由此可判断,作者认为新装置有利于环保。2.D细节理解题。本题题干意为:为什么Babbitt的团队要进行这项研究?根据第二段第一句可知,为了弄清楚这些设备消耗多少电量,Babbitt和同事们持续跟踪每个产品在其使用周期内的环境成本。D项意为“为了查清这些装置耗费的电量。”,与文章内容一致。3.B细节理解题。本题题干意为:以下哪种装置耗能最少?根据第一段可知新装置耗费的能量较少,而第二段则指出与其他几种装置相比,tablets(平板电脑)出现的时间最晚,为最新的科技产品,而且
10、最后一段指出,tablets具有多种功能,比电视和台式电脑消耗的能量少,故B项正确。4.A推理判断题。本题题干意为:文章建议人们如何处理陈旧的电子设备?最后一段讲到了解决方案,本段指出,研究人员探索了消费者用有多种功能的电子产品替换陈旧产品后的结果。由最后一句可知,用平板电脑代替电视和台式电脑来收看娱乐节目,会减少44%的能源消耗。由此可知文章建议人们不要再使用陈旧的电子设备,故A项正确。难句分析难句分析原句:Wemaythinkwereaculturethatgetsridofourworntechnologyatthefirstsightofsome-thingshinyandnew,bu

19、.Positive.C.Disapproving.D.Uncaring.答案答案语篇解读本文讲述了经过多年激烈的争论,美国政府终于从加拿大重新把14匹灰狼引入黄石国家公园,以恢复当地的生态平衡。1.D主旨大意题。全篇自始至终谈论的就是重新把灰狼引入美国黄石国家公园,故正确选项应为D。2.C词义猜测题。短文第二段描述灰狼曾经在黄石地区和美国大陆的大部分地区生活,由于人类的发展,到20世纪20年代,灰狼几乎在黄石地区消失了。由此可以判断肯定是人类的发展“逼走”了灰狼,迫使灰狼迁徙到加拿大的森林地区。故正确选项为C。3.A推理判断题。根据第三段可知灰狼的消失产生了许多出乎意料的结果。作为灰狼食物来源
20、的其他动物繁衍过快,导致当地植被被过度消耗,公园的植物多样性遭到破坏;没有了天敌灰狼,当地的郊狼迅速繁衍,而郊狼杀死了公园大部分的红狐,也让河狸丧失了栖息之地。因此考生可以判断黄石国家公园的生态系统遭到破坏,故最佳选项为A。4.B观点态度题。从短文中最后一段最后一句中的avaluableexperiment可以推断出作者的态度是积极的,因此B项正确。高级语块高级语块1.consumev.消耗;吃2.opposev.反对3.reintroducev.重新引入Passage3(2015课标全国,C)词数:269Morestudentsthaneverbeforearetakingagapyear(
