注意:1.詞數(shù)100左右;?2.短文題目已為你寫好。ThePersonI’mGratefulto____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________答案以及解析第一部分閱讀理解第一節(jié)A答案：13CBA解析：1.由第一本書簡介中的"awriterdisappearedataconferenceandwasfounddeadatanotherplace.Thirtyyearslater,ayoungmaninterviewedsurvivorsfromtheconference,tryingtouncoverthetruthaboutwhathappenedanditsconsequences"可知，這本書屬于偵探小說。2.對比四本書的內(nèi)容簡介可知，第二本書WhenBreathBeesAir的作者在其自傳中探討了生命和死亡的話題。3.題干問的是最后一本書的主人公，根據(jù)該書簡介中的"Inthisbook，BobbyisspeakingtoBessoncemore，inavoiceaslovingasiteverwasinlifeandbringsusseveralgenerationsofbravewomen"可知，主人公是作者的祖母BobbyBell。B答案：47CABB

解析：4.細(xì)節(jié)理解題。根據(jù)文章第一段第二句butluckilytherearenumerousbooksandonlinevideosthatwillhopefullygivemetheinformationIneed.但是幸運(yùn)的是，有很多書和網(wǎng)上視頻可以給我提供我需要的信息。故選C。

5.推理判斷題。根據(jù)文章第二段前兩句Bookshopsthesedaysarefulloftitleswhichclaimtoboostyourselfconfidence,yourwealth,yourlovelifeoryourcareer.Someclaimtoimproveyourlifewithinsevendays!如今，書店里到處都是聲稱能提升你的自信，財富，生活或事業(yè)的書名。有些聲稱能在七天內(nèi)改善你的生活。可知這些自助書籍可能會給你提供一些成功所需的關(guān)鍵因素。D項(xiàng)干擾項(xiàng)。這些只是聲稱能在7天內(nèi)改善你的生活，但不一定真能改善。

6.細(xì)節(jié)理解題。根據(jù)文章第五段第三句Interestingly,psychologistCarolineBeaton,sayspeoplecalled'millennials'areselfcritical–theyareawareoftheirownfaults–whichalsomeansthey'remorelikelytospendtimeandmoneyonselfhelp.有趣的是，心理學(xué)家比頓卡洛琳說被稱為千禧一代的人是自我批評型的，他們能意識到自己的缺點(diǎn)。這就意味著他們可能更可能花費(fèi)時間和金錢在需求自我提升上。故選B.他們意識到自己是不完美的有缺點(diǎn)的。

7.推理判斷題。根據(jù)文章一段第二句Thealternativetofindingahappierlifeisjusttoetotermswithyourselfasyouare…，找到更幸福生活的一種辦法就是忍受并接受現(xiàn)在的你。作者也是從書上了解到的。故選B。C答案：811BCDA

解析：8.細(xì)節(jié)理解題。根據(jù)第一段中“Butastheyhavedroppedinpricemorepeoplehavebeguntousethem.Rescueworkersandfarmersareamongthenewusers.(但隨著價格的下降，越來越多的人開始使用它們。救援人員和農(nóng)民都是新用戶)”可知，救援人員和農(nóng)民開始使用無人機(jī)，是因?yàn)闊o人機(jī)的價格下降了。故選B。

9.細(xì)節(jié)理解題。根據(jù)第三段中“Hehelpedcreateapanythatdevelopedasmalldronethatcouldbecontrolledbypeopleontheground.Theycalledit"Agridrone".Itusesaspecial"opticalsensor"toexaminecrops.(他幫助創(chuàng)建了一家公司，該公司開發(fā)了一種可以由地面人員控制的小型無人機(jī)。他們稱之為“農(nóng)業(yè)無人機(jī)”。它使用一種特殊的“光學(xué)傳感器”來檢測農(nóng)作物)”可知，RomainFarour公司研發(fā)的無人機(jī)能幫助農(nóng)民檢查他們的莊稼。故選C。

10.細(xì)節(jié)理解題。根據(jù)第三段中“Thesensoronthedronerecordsfourdifferentcolored"bands"ofsunlightthatarereflectedoffthecrops.(無人機(jī)上的傳感器記錄農(nóng)作物反射的四種不同顏色的“波段”陽光)”可知，無人機(jī)上的傳感器能記錄農(nóng)作物反射的陽光。故選D。

11.推理判斷題。根據(jù)最后一段“RomainFarouxsaysfarmersuseinformationcollectedbytheAgridronetoplacefertilizeronlyinareaswhereitwasneeded.Thissavesmoneyandreducespollution.Beforetheyusedthedrones,farmerswouldputthesameamountoffertilizereverywhere.Dronesalsosavetimebecausefarmerscanexamineuptothreehectareinaboutaminute.(RomainFaroux說，農(nóng)民利用農(nóng)業(yè)無人機(jī)收集的信息，只在需要化肥的地方施肥。這節(jié)省了資金，減少了污染。在使用無人機(jī)之前，農(nóng)民會在各地撒同樣數(shù)量的肥料。無人機(jī)還可以節(jié)省時間，因?yàn)檗r(nóng)民可以在大約一分鐘內(nèi)檢查三公頃的土地)”可推知，無人機(jī)的使用是環(huán)保的。故選A。D答案：1215ABDB解析：12.根據(jù)畫線詞上文的"Thesoftcreaturesarenaturallyhalftransparentandgettheirbrilliantcolorfromalgae(藻類）livinginsidethem"和下文的"theinterdependentrelationshipwithalgae,typicallypushingthemoutandturningwhite"可知，珊瑚蟲因生活在它體內(nèi)的藻類獲得了絢麗的色彩，它們相互依賴，當(dāng)珊瑚蟲受到高溫或污染的壓力時，它們通常會將藻類驅(qū)逐出去，變成白色，故此處應(yīng)表示"它們結(jié)束與藻類的相互依存的關(guān)系"。end"(使）結(jié)束，(使)停止"可解釋畫線詞意思。13.根據(jù)第三段的"harvestingsamplesofthecoralsthatsurvivedtheenvironmentalstressnaturally,keepingthemtomakethemreproduce,andthenreattachingthemtothereef.Theyhave46,000coralsonplasticframesunderthesea…ondamagedreefs"可知，Muller和她的團(tuán)隊正在采集那些在自然環(huán)境壓力下存活下來的珊瑚蟲樣本，在海底人工養(yǎng)殖它們，然后使它們重新回到珊瑚礁上生存。由此可知，Muller和她的團(tuán)隊在人工培育珊瑚蟲。14.根據(jù)題干中的Cunning'swords可將解題依據(jù)定位至最后一段，根據(jù)最后一段的"Thebigquestionscientistsneedinvestigate,addsCunning,ishowmuchmoreheatcoralscanadaptto"可知，科學(xué)家還需要研究存活下來的珊瑚蟲還能適應(yīng)再高多少的溫度，即珊瑚蟲能適應(yīng)的最高溫度還是未知的。15.綜合全文可知，文章首段介紹珊瑚礁面臨的困境，以引出文章的核心內(nèi)容:科學(xué)家們?yōu)榱苏壬汉鹘高M(jìn)行各種科學(xué)研究和做出種種努力，如建立海洋保護(hù)區(qū)、人工培育珊瑚蟲、研究具有耐高溫基因的珊瑚蟲等。故B項(xiàng)最適合作本文標(biāo)題。第二節(jié)答案：FCDAE解析：16.根據(jù)上文

Youprobablyalreadyknowthatexercisingisnecessarytopreservemusclestrength,keepyourheartstrong,andhelpyoukeepahealthybodyweight.可知，你可能已經(jīng)知道鍛煉對于保持肌肉力量，保持心臟強(qiáng)壯，以及幫助你保持健康體重是必要的。故此空應(yīng)該與鍛煉的其他的未知的作用有關(guān)。F項(xiàng)意為“但是運(yùn)動也可以幫助提高你的記憶力和思考能力”，承接上文，符合語境。故正確答案為F。17.根據(jù)上文

Itactsdirectlyonthebrainbyencouragingthegrowthofnewbloodvessels(血管)inthebrain.可知，它直接作用于大腦，鼓勵大腦中新血管的生長。故此空應(yīng)該與鍛煉對大腦的作用有關(guān)。C項(xiàng)意為“它甚至能促進(jìn)新腦細(xì)胞的整體健康”，承接上文，符合語境。故正確答案為C。18.根據(jù)上文

Exercisecanalsoimprovememoryandthinkingskillsindirectly.可知，運(yùn)動也可以間接地提高記憶力和思維能力。故此空應(yīng)該說明運(yùn)動如何間接地提高記憶力和思維能力。D項(xiàng)意為“它能改善人們的睡眠，減少他們的壓力和焦慮”，承接上文，符合語境。故正確答案為D。19.根據(jù)上文

Isoneexercisebetterthananotherintermsofbrainhealth?可知，就大腦健康而言，一種運(yùn)動比另一種更好嗎?故此空應(yīng)該回答這個問題。A項(xiàng)意為“我們不知道這個問題的答案”，承接上文，符合語境。故正確答案為A。20.根據(jù)上文

Severalstudieshaveshownthatittakesaboutsixmonthstostartgettingthebenefitsofexercise.可知，一些研究表明，大約需要6個月的時間才能開始獲得鍛煉的好處。故此空應(yīng)該說明基于6個月才能開始獲得鍛煉的好處這一研究結(jié)果應(yīng)該怎么做。E項(xiàng)意為“因此，他提醒你在尋找最初的結(jié)果時要有耐心”，承接上文，符合語境。故正確答案為E。第二部分語言知識運(yùn)用第一節(jié)答案：2125BADCC2630DABBD3135BCCAD3640ABCAD

解析：21.考查名詞。此空通過下文意思可知答案，意為“非賣品，拒絕出售(sale)”。

22.考查動詞。這幅畫如此美麗以至于參加(attended)展覽的人都在詢問價格。

23.考查動詞短語。無論他要價(chargefor)多少，他們都想他出售這幅畫。

24.考查名詞。我只將它賣給懂得它的價值(value)的人。

25.考查動詞短語。此時，有一位老人走上前去(cameover)，說:"我想買這幅畫，這盒子里的東西就是它的價錢(price)"。
