10、imeslongerthanconventionalroads”可知，這種塑料公路使用壽命比傳統(tǒng)公路長兩到三倍。也就是說，相較于傳統(tǒng)公路，塑料公路更耐用。故選A。 3.What’stheauthor’spurposeofwritingthispassage? A.Toshowdifferentwaystorecycleplastic.

19、mmercialsareonlyvisiblefromonelocation. 答案　D 解析　推理判斷題。根據(jù)第三段中的“Whenyoupassdirectlyinfrontoftheimage，youseeit.Itappearstobehugeandhunginmid-air，butotherscan’tseeit.”可知，你從圖像前徑直走過時，就能看到它。它看起來很大而且懸浮在半空中，不過別人看不到。由此可推知，Lightvert公司的商業(yè)廣告只能從某個特定的位置看到。故選D。 5.Whatdoestheunderlinedsentenceinthefourthparagraph

20、imply? A.Somepeoplecan’tlivewithsomanyads. B.Someadsdon’tachievethedesiredresults. C.Somepeoplefeelconfusedaboutendlessads. D.Somepeoplearemoreusedtotraditionalads. 答案　A 解析　句意理解題。根據(jù)第四段的內容，尤其是“InMoscow，forexample，anewformofadvertisingtargetingmotoristshassplitopinion.”可知，莫斯科民眾對一款面向汽車司機的新廣告褒貶不一，

21、也就是說，人們對這類廣告在意見上有分歧。由此可知，畫線句應是指有人無法忍受這樣一個被各種廣告充斥的世界。故選A。 6.Whatistheproblemwithdigitalbillboardsaccordingtosomeobservers? A.Theyfailtoremindpeopleofdangerontheroads. B.Theymakepeoplelessconcentratedondriving. C.Theyhaveatendencytoviolatepeople’sprivacy. D.Theyareattractivebutkindofharmfultooure

A.TheF

23、utureofAdvertising B.HighTechnologyinAdvertising C.AWorldFloodedwithAdvertising D.DifferentOpinionsonAdvertising 答案　A 解析　標題歸納題?？v觀全文，尤其是第一段中的“Imagineafuturewhere...ads”可知，本文主要講述了未來廣告形式的相關內容，故A項作本文標題最佳。 3 話題：環(huán)境保護 難度：★★ 建議用時：7分鐘 Theworldisliterallyagreenerplacethanitwas20yearsago，anddatafro

31、eincrediblyadaptable.” 語篇解讀　本文是一篇說明文。NASA的衛(wèi)星資料顯示，中國和印度的行動主導了地球變綠。 8.TheEarthisgettinggreenermainlybecauseof. A.theexpandingofleafareaintropicalcountries B.thedeterminedeffortstopreserveAmazonrainforests C.thetree-plantingprogramsandintensiveagriculture D.afavorableclimateandincreasedCO2inthe

32、atmosphere 答案　C 解析　細節(jié)理解題。根據(jù)第一段中的“Theworldisliterallyagreenerplacethanitwas20yearsago，anddatafromNASAsatelliteshasrevealedasourceformuchofthisnewgreeningphenomenon：ChinaandIndia”和第五段中的“China’soutsizedcontributiontotheglobalgreeningtrendcomesinlargepart(42%) fromprogramstoconserveandexpandforests...

33、India—comesfromintensive(集約的) growingoffoodcrops.”可知，中國和印度正引領著地球綠化的增加，而這主要源于中國的植樹計劃和兩國的集約化農業(yè)。故選C。 9.Whichofthefollowingstatementsmaytheresearchersagreewith? A.ThegreeningtrendinIndiawillcontinuetogoupwards. B.More“greening”meansbettercontrolofclimatechange. C.Landoverusethreatensthesuccessintheg

34、reeningontheEarth. D.Thesustainabilityinglobalecosystemswillbegreatlyimproved. 答案　C 解析　推理判斷題。根據(jù)第三段的內容可知，中國和印度的綠化面積占全球綠化面積的三分之一，但僅有全球9%的植被覆蓋面積，考慮到人口稠密的國家普遍存在過度開發(fā)導致土地退化的現(xiàn)象，這是一個令人驚訝的發(fā)現(xiàn)。由此可推知，人們對土地的過度使用威脅著地球綠化的成功。故選C。 10.Whatdoestheunderlinedword“offset”inthelastbutoneparagraphprobablymean? A.Preve

35、nt. B.Survive. C.Interrupt. D.Balance. 答案　D 解析　詞義猜測題。根據(jù)倒數(shù)第二段最后一句可知，巴西和印度尼西亞等熱帶地區(qū)的生態(tài)系統(tǒng)的可持續(xù)性和生物多樣性所受的負面影響仍然存在。再結合第三段的內容可知，畫線詞所在句的含義應是：研究人員指出，印度和中國主導的全球綠化的增加并不能抵消巴西和印度尼西亞等熱帶地區(qū)自然植被減少所帶來的損失。offset是“抵消，彌補”之意，與balance“相抵，抵消”的含義相近。故選D。 11.HowdoesNemanifeelaboutthefindings? A.Theyareapositiveindicatorof

36、overallhumannature. B.Theiraccuracyandreliabilityneedtobefurtherproved. C.Theyundervaluehumans’contributiontotheenvironment. D.Theirsignificanceforfutureresearchcannotbeoveremphasized. 答案　A 解析　推理判斷題。根據(jù)最后一段中的“Oncepeoplerealizethere’saproblem，theytendtofixit...”“...inthe90s，peoplerealizedit；andto

37、daythingshaveimproved.Humansareincrediblyadaptable.”可知，當人們意識到問題時，他們會想辦法來解決。人類具有出乎意料的適應能力。由此可知，研究結果表明了人性積極的一面。故選A。 題組訓練二 1 話題：文字的重要性 難度：★★ 建議用時：7分鐘 [2019·江西省名校(臨川一中、南昌二中)聯(lián)考] Astheinternationaldemandfornarrative(敘事的) film/TV content continues to increase with popular streaming services like N

44、 A.Economicbenefits. B.Internationalreach. C.Culturalinfluence. D.Educationalimportance. 答案　A 解析　細節(jié)理解題。根據(jù)第二段最后一句“Thenarrativefilmindustryisamoneymakerthatdwarfs(使相形見絀) thepublishingindustry.”可知，敘事電影行業(yè)是一個令出版行業(yè)相形見絀的賺錢行業(yè)，由此可知，敘事電影行業(yè)在經(jīng)濟利益方面使文字變得尷尬。故選A。 2.Whydoestheauthorvaluetheroleofthewrittenwor

D.Critical. 答案　C 解析　推理判斷題。根據(jù)倒數(shù)第二段第二句“Instead，Ihavealwaysfeltitnecessarytoadapttoadvancingtechnology.”可知，作者覺得有必要適應先進的技術，由此可推知，作者對技術持積極的態(tài)度。故選C項。 4.What’stheauthorconcernedabout?
