专题05生态环保类PPPaaarrrttt111题题题型型型总总总览览览【题型综述】―生态环保‖是普通高中英语课程标准话题之一，亦是高考英语常考话题。本话题包括动植物保护、生态保护、自然灾害、环境污染和保护等方面。这些话题与学生的生活息息相关，联系密切。通过对这些话题的学习以及高考英语对这些

话题的考查，可以让学生多注意身边的人和事、关注社会环境、树立环保意识、学会与大自然和谐相处。【技巧点拨】1.运用语篇结构，概括全文主旨大意，明晰写作意图。在阅读时，首先用略读法快速浏览每段的首尾句，分析原文的文本结构，然后根据作者谋篇布局的逻辑线索归纳主旨大意。如果文章中含

有标题、副标题、图片等，在概括全文主旨大意和写作目的时需要重点考虑。根据英语说明文思维模式特征，作者一般都会开门见山，直奔主题。结尾通常也是中心思想的概括，并与导语相呼应。因此在做主旨大意、写作意图和最佳标题等题目时，需要重点关注首尾段落里面

高频复现的词汇和内容。导语、主体和结尾是有机整体，解题时要综合起来进行判断。2.利用文中语境线索分析长难句，进行逻辑推理判断。在阅读解题时，第一步可以浏览全文，掌握中心大意。第二步可以根据题干要求，用查读法（scanning）再快速定位

到相关段落。第三步可以重点搜索段内的标志词，利用标志词所提供的逻辑关系找到细节信息，如数据、例子、原因和结果等。如果句子成分复杂，有生词，也不要烦躁退缩，分析主句和从句或非谓语动词之间的关系，抓住行文逻辑的标志词，层层剖析，露出主干部分，就能明晰句意，弄懂作者的真实意图。【读相关词】1.ha

鼠们每年都在破坏大片的湿地，因此设计师称这是一种环保的举措，科学家们也对海狸鼠损坏生态平衡表示了担忧。28．推理判断题。根据第二段UnusualfashionshowsinNewOrleansandBrooklynhaveshowcasednutriafurmadeintoclo

thesindifferentstyles.―Itsoundscrazytotalkaboutguilt-freefur-unlessyouunderstandthatthenutriaaredestroyin

reeMcCree说：―除非了解海狸鼠正每年破坏大片湿地，否则谈论无罪感皮衣是很疯狂的事情‖，可以判断出由于海狸鼠对生态造成了巨大的破坏，这场海狸鼠皮衣时装秀销售的是无罪恶感皮衣。故选A。29．推理判断题。根据第三段ScientistsinLouisianaweresoconc

ernedthattheydecidedtopayhunters$5atail.得知，科学家们如此担心以至于他们决定按照一条海狸鼠尾巴付给猎人们5美元，可以推断出科学家们担忧海狸鼠们严重破坏生态平衡，。故选A。30．词义猜测题。根据第五段Thefurtradekeptnutriainc

heckfordecades,butwhenthemarketfornutriacollapsedinthelate1980s,thecat-sizedanimalsmultipliedlikecrazy.得知，毛皮贸易使海狸鼠受到了几十年的控制，但是当海狸鼠市场在20世纪80年代末崩溃时，

这种猫大小的动物数量疯长，根据but判断，这是转折关系，以前由于皮毛交易，海狸鼠处于控制，现在这种海狸鼠之所以能够数量激增，是由于市场不再销售海狸鼠皮毛导致的，可以推断出划线词collapsed是和D.crashed倒闭的意思最相近。故选D。31．推理判断题。根据第

example,discoveredthatgreenerareasofthecityexperiencedlesscrime.Inanother,employeeswereshowntobe15%moreproductivewhen

theirworkplacesweredecoratedwithhouseplants.可知例如，在俄亥俄州扬斯敦进行的一项研究发现，城市绿化较好的地区犯罪率较低。在另一项研究中，当员工的工作场所被室内植物装饰时，他们的工作效率会提高15%。由此可知，第一段的主旨是关于绿色植物的益处。故选D。3

nsmission.Glowingplantscouldreducethisdistanceandthereforehelpsaveenergy.可知照明约占美国总耗电量的7%。由于照明通常远离电源，例如从发电厂到偏僻公路上路灯的距离，在传输过程中会损失大量能

源。发光的植物可以缩短这段距离，从而帮助节约能源。结合文章主要说明了绿色植物对人们很有好处，因此麻省理工学院的工程师开发了一种发光植物，文章介绍了他们发明这种植物的过程，以及这种植物的一些优势，指出在未来发光植物有可能取代路灯，达到节约能源的作用。由此可知，C选项―发光的植物能取代

已经损失了一半的大树，而气候变化似乎是其主要因素。1．主旨大意题。第二段中，作者用具体数据说明了大树损失在各个地区的严重程度，没有任何地区幸免或不受影响，故选A。2．推理判断题。根据第三段最后一句Agg

ressivewildfirecontrolhasleftCaliforniaforestscrowdedwithsmalltreesthatcompetewithbigtreesforresources(资源).可知，对野火的控制使得加利福尼亚的森林里挤满了小树，与大树争夺资源，也就是对野火的

控制是善意的，但对大树产生了不利的影响。故选D。3．细节理解题。根据最后一段thebiggestfactorsdrivingupwaterstressinthestatehavebeenrisingtemperatures,whi

than12.35millionacresofland.Atleast25peoplehavebeenkilledand2000homesdestroyed(这个季节，澳大利亚的森林大火已经烧毁了超过1235万英亩的土地。至少

25人死亡，2000座房屋被毁)‖可知，本段的数字表明森林大火产生的严重后果。故选B项。2．词句猜测题。由第二段―ZekeHausfather,anenergysystemsanalystandclimateresearcheratBerkeleyEarth,saidwa

rmertemperaturesandextremeweatherhavemadeAustraliamoresusceptibletofiresandincreasedthelengthofthefire

season(加州大学伯克利分校地球分校的能源系统分析师和气候研究员泽克·豪萨福尔说，气温升高和极端天气使澳大利亚更容易发生火灾，并延长了火灾季节的长度)‖可推测，气温升高和极端天气更容易发生火灾，moresusceptibleto意为―更容易受到……影响‖，与C项―Verylike

lytobeinfluencedby(很容易受……的影响)‖意思相近。故选C项。3．推理判断题。由第三段的―Hesaidthatonceanareaexperiencesdroughtconditionsfortwomonths

ormore,itincreasestheriskoffirescatchingandspreading.Thosechangingweatherpatternsduetoglobalwarmingmakedroughtevent

slonger(他说，一旦一个地区经历了两个月或更长时间的干旱，它就会增加火灾发生和蔓延的风险。那些由于全球变暖而改变的天气使得干旱持续的时间更长)‖可推断，全球气候变暖是森林火灾的根本原因。故选B项。4．推理判断题。根据最后一段内容可知，气候专家强调

，气候变化不是野火严重的唯一因素。土地的管理方式也会影响火灾可用燃料的数量。诸如控制性燃烧和其他因素等做法可能会影响对人和财产的风险，火灾管理资源分配方式改变的同时，改变这些政策有很大的潜力限制未来野火造成的损害。可推断在最后一段作者想要介绍一些关于减少火灾损失的建议。故选D项。
