浙江专版2019高考英语二轮复习专题7阅读理解类型6生态环保讲练考查要点方法技巧1.生态环保的现状，造成的影响2．生态环境被破坏的因素，产生的后果3．保护生态环境的措施、步骤1.理清文章的行文结构，把握主旨大意2．抓住造成生态环境变迁的原因这一主线3．领会作者所透露出的观点态度California Condor's Shocking RecoveryCalifornia condorCalifornia condors are North America's largest birds，with winglength of up to 3 meters.In the 1980s，electrical lines and lead poisoning(铅中毒) nearly drove them to dying out.Now，electric shock training and medical treatment are helping to rescue these big birds.In the late 1980s，the last few condors were taken from the wild to be bred(繁殖)．Since 1992，there have been multiple reintroductions to the wild，and there are now more than 150 flying over California and nearby Arizona，Utah and Baja in Mexico.Electrical lines have been killing them off.“As they go in to rest for the night，they just don't see the power lines，” says Bruce Rideout of San Diego Zoo.Their wings can bridge the gap between lines，resulting in electrocution (电死) if they touch two lines at once.So scientists have come up with a shocking idea.Tall poles，placed in large training areas，teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock.Before the training was introduced，66% of set­free birds died of electrocution.This has now dropped to 18%.Lead poisoning has proved more difficult to deal with.When condors eat dead bodies of other animals containing lead，they absorb large quantities of lead.This affects their nervous systems and ability to produce baby birds，and can lead to kidney(肾) failure and death.So condors with high levels of lead are sent to Los Angeles Zoo，where they are treated with calcium EDTA，a chemical that removes lead from the blood over several days.This work is starting to pay off.The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011.Rideout's team thinks that the California condors' average survival time in the wild is now just under eight years.“Although these measures are not effective forever，they are vital for now，” he says.“They are truly good birds that are worth every effort we put into recovering them.”63．California condors attract researchers' interest because they ．A．are active at nightB．had to be bred in the wildC．are found only in CaliforniaD．almost died out in the 1980s64．Researchers have found electrical lines are ．A．blocking condors' journey homeB．big killers of California condorsC．rest places for condors at nightD．used to keep condors away65．According to Paragraph 5，lead poisoning ．A．makes condors too nervous to flyB．has little effect on condors' kidneysC．can hardly be gotten rid of from condors' bloodD．makes it difficult for condors to produce baby birds66．This passage shows that ．A．the average survival time of condors is satisfactoryB．Rideout's research interest lies in electric engineeringC．the efforts to protect condors have brought good resultsD．researchers have found the final answers to the problem语篇解读：本文是一篇说明文。

美国加利福尼亚秃鹰由于触电和铅中毒而濒临灭绝，研究人员采取了一些措施来挽救秃鹰，从而使这一种群渐渐恢复了生机长难句解读：So condors with high levels of lead are sent to Los Angeles Zoo，where they are treated with calcium EDTA，a chemical that removes lead from the blood over several days.分析：本句为复合句主语部分有with短语作定语，where引导的定语从句修饰前面的Los Angeles Zoo，a chemical为calcium EDTA的同位语，其后是that引导的定语从句翻译：于是，体内含有高剂量铅的秃鹰被送往洛杉矶动物园在那里，用一种名为EDTA的钙物质为其治疗，这是一种化学药物，能够在几天时间内清除血液中的铅63．D　[推理判断题根据第一、二段内容可知，20世纪80年代，由于触电和铅中毒，加利福尼亚州的秃鹰濒临灭绝，20世纪80年代末，仅剩的几只秃鹰从野外被带回繁殖，由此可推断正是秃鹰濒临灭绝才引起了研究人员的注意和兴趣，故选D项。

]64．B　[细节理解题根据第三段内容可知，电线一直是使秃鹰丧命的杀手，并且解释原因说，秃鹰晚上休息的时候看不见电线，而它们宽大的翅膀正好同时搭在两根电线上，于是它们立刻就被电死了，故选B项]65．D　[细节理解题根据第五段内容可知，铅中毒影响了秃鹰的神经系统和繁殖能力(affects their nervous systems and ability to produce baby birds)，并且可以导致它们肾衰竭和死亡，故选D项]66．C　[推理判断题本文主要介绍了美国加利福尼亚秃鹰濒临灭绝以及科研人员为挽救它们而展开的救援和研究工作，且实施的措施有了回报(pay off)，故选C项]A(2016·长沙四校模拟)Eco­friendly Car RacerCan you image a car racer is so eco­friendly that its tyres are made from potatoes，its body is created from hemp (大麻)and rapeseed oil and it runs on fuel made from wheat and sugar beet? The one­seater racing car called Eco One is built by experts from Warwick University，who hope that Eco One will be adopted by the automotive industry.It is sold at ￡41，000.Pollution­sensitive DressDon't be caught outside unaware of pollution levels in the air.The pollution­sensitive EPA Dress by Stephanie Sandstrom notices pollution in the air accordingly.This dress—which is actually quite pretty—looks like you pull it from the bottom of the dirty laundry pile when the air is dirty.It might protect your health by advising you to stay indoors for the day，but it won't do you any favor if you're meeting with clients.Eco­friendly UmbrellaTraditional umbrellas come with a fixed surface.Although it's changeable，you cannot replace it easily.This eco­friendly design is more flexible.It's actually only an umbrella skeleton without any surface，which can be folded，so you c。
