了很大破壞和影響。12．選A詞義猜測題。根據(jù)第一段“Itcausedwidespreaddamageandresultedinmanychanges.”及第二段畫線詞后文“hundredsofhomes,bridgesandroadwaysinnearbymunities”可知，devastated意思與ruined“毀壞”相近。13．選B細節(jié)理解題。根據(jù)第二段可知，洪水產(chǎn)生了惡劣的影響。14．選D細節(jié)理解題。根據(jù)第三段“Thecitygotitswaterfromtheriverandwasforcedtocloseitstreatmentplant(工廠)becauseitcouldn'toperateeffectivelywithwaterlevelsthathigh.”可知，比林斯市的處理廠由于洪水被強行關(guān)閉。15．選A推理判斷題。根據(jù)最后一段“Thenorthernhalfoftheparkislikelytoremainclosedoverthesummer.Thiswillgreatlyaffectlocaleconomiesthatdependonsummertourists.Butwehavefaithintheparkrepairsandeconomicrecovery.”可知，黃石的官員對于公園維修和經(jīng)濟復蘇持積極態(tài)度。語篇解讀：本文是一篇說明文，介紹了空降森林滅火員(smokejumpers)這一特殊的人群。16．選E后文“Smokejumpershelptostopthis.”中的“this”指的就是火災(zāi)造成的損失和傷害，所以E項“同時，家園被毀，成千上萬的人失去生命”與前文數(shù)百萬公頃的森林被燒毀是并列關(guān)系，都是火災(zāi)造成的損失。故選E。17．選A這一段解釋了什么是smokejumper?？崭裉幣c下一句“Smokejumpersareaspecialtypeoffirefighters.”構(gòu)成了自問自答的關(guān)系。故選A。18．選F前文談到了smokejumpers在工作期間需要攜帶的東西，因此設(shè)空處進一步闡述他們也會攜帶水，too是關(guān)鍵詞。故選F。19．選C從后文的例子可知，此處說到了這一職業(yè)對于體重的要求，所以選擇C項。20．選D由前文可知，smokejumpers必須有野外生存的能力，知道怎樣在森林中找到食物，知道怎樣用樹木制造簡單的家具。所以D項“這意味著這項工作是危險的，需要花很長的時間”承接上文。第二部分語篇解讀：本文是一篇記敘文，講述了夫妻二人援救被洪水圍困的人們，體現(xiàn)了洪水無情人有情的精神。21．選D根據(jù)上文“Thecaller'sbrotherandher”和下文“Theteenager”可知，打電話的人是女的，她打電話說她的家人被困，“女兒”符合語境。22．選C根據(jù)上文“trappedontheirroofinWaverlybecauseoftherisingfloodwater”可知，他們被困在屋頂，因此打電話的人是懇求JoelBoyers來營救他們。order“命令”；attract“吸引”；beg“懇求”；challenge“挑戰(zhàn)”。23．選B根據(jù)上文“headinghomeintheirhelicopter(直升機)”可知，他們乘坐直升機回家，因此在如此惡劣條件下飛行是很危險的。故選B。24．選A根據(jù)上文“BoyerslookedwesttowardsWaverlyatthestormclouds.”可知，當時烏云密布，情況緊急，因此他立即將求救者弟弟的地址輸入手機。immediately“立即地”；secretly“秘密地”；gradually“逐漸地”；creatively“創(chuàng)造性地”。25．選D根據(jù)下文“Boyerscouldn'tusehisphonetolocate”可知，Boyers不能使用他的手機去定位，由此可知他將求救者弟弟的地址輸入手機。故選D。26．選A根據(jù)上文“Soon,heandAmongwereintheair”可知，他們很匆忙，還沒有準備好會在韋弗利將會看到什么。unprepared“沒有準備好的”；intended“計劃的”；relieved“放心的”；recognized“公認的”。27．選B根據(jù)下文“Peoplewereholdingontoanythingthatdidn'tmove—roofs,trees.”可知，人們緊緊地抓住不能移動的任何東西，由此可知水流很急。peaceful“和平的”；rapid“迅速的”；familiar“熟悉的”；clean“干凈的”。28．選C根據(jù)下文“meaningBoyerscouldn'tusehisphonetolocatethe”可知，Boyers不能定位到他尋找的房子，因此洪水也破壞了手機服務(wù)。revise“復習，修正”；deliver“運送”；damage“破壞”；register“注冊”。29．選A根據(jù)上文“weretrappedontheirroof”可知，他們被困在屋頂，因此Boyers尋找他們所在的房子。故選A。30．選D根據(jù)上文“weretrappedontheirroof”可知，他們被困在屋頂，因此Boyers和Among在搜尋他們。debatewith“爭論”；adaptto“適應(yīng)”；menton“評論”；searchfor“搜尋”。31．選A根據(jù)下文“getthemonboard”可知，要讓求救者上來，他必須找到著陸(land)的地方。故選A。32．選D根據(jù)上文“Theteenagerheldontoabranchwithonehandandtheotherheldadogshe'
