答案以及解析一答案：1.B;2.C;3.D;4.D

解析：1.主旨題。根據(jù)全文可知,作者根據(jù)專家研究,告訴大家"穿襪子睡覺有助于睡眠",A廣告,B生活方式,C觀點(diǎn)/評價,D熱點(diǎn)話題,該文章最可能出現(xiàn)在生活方式板塊,因此選擇B。

2.細(xì)節(jié)題。根據(jù)題干中的whatchangedoeswarmfeetbringtothebody把答案定位在第4、5段。根據(jù)第4段warmingthefeetbeforegoingtosleepusingawarmfootbathorbywearingsockspromotesbloodvesselwidening,whichinturnlowersthebody'scoretemperature。可以排除B選項(xiàng),并確定選C選項(xiàng)。根據(jù)第5段Thewarm-sensitiveneuronsinthebrainbecomemoreactivewhenthere'satemperaturedifferencebetweenthebody'scoreandthefeet...theseneuronsbecomemoreactiveaswegetsleepyandslowdownaswewakeup,可以排除A選項(xiàng)A。D選項(xiàng)無中生有,原文沒有提到bloodpressure?？芍鸢高xC。

3.細(xì)節(jié)題。根據(jù)題干中的brain'swarm-sensitiveneurons把答案定位在第5段。根據(jù)theseneuronsbecomemoreactiveaswegetsleepyandslowdownaswewakeup,sothatwarmingupthefeetbeforebedtimemaygivethemanextradrive,makingyoufeelsleepier,可知答案為D。

4.細(xì)節(jié)題。根據(jù)最后一段,A選項(xiàng)并不是thesmallstudy的結(jié)果。根據(jù)special"sleepingsocks"notonlyspedupthecomingofsleep,butincreasedoverallsleeptimebyanaverageof30minutesandcutnighttimewakingepisodesinhalf,排除B選項(xiàng)、C選項(xiàng)。選擇D選項(xiàng)。二答案：1.A;2.C;3.C;4.B

解析：1.考查推理判斷。根據(jù)第二段中的"TheArizonadesert…unlesshehadoneofOmarYaghi'snext-generationwaterharvesters"可知,作者提及亞利桑那州的沙漠是為了引出OmarYaghi的下一代吸水設(shè)備以及下文對其的介紹。故選A。

2.考查細(xì)節(jié)理解。根據(jù)第三段中的"WhatmakesitworkisaspecialmaterialrailedaMOF"可知,使吸水設(shè)備工作的是一種叫做金屬有機(jī)框架的特殊材料,故金屬有機(jī)框架在該設(shè)備中起了關(guān)鍵作用。

3.考查詞義猜測。根據(jù)畫線短語前的Thesecrystalline(結(jié)晶的)groupsofmetals...canbemadeintomaterialswithanextremelyhighabsorptionability,attractingspecificmoleculestotheirsurfaces"可知,這些由有機(jī)分子連接在一起的金屬結(jié)晶群可被制成吸收能力極高的材料,以吸引特定分子到它們的表面,即金屬有機(jī)框架可以吸附各種液體和氣體,故holdonto"抓緊"和畫線短語clingto的意思最為接近。

4.考查推理判斷。通讀全文可知,本文主要講述了金屬有機(jī)框架可以幫助解決沙漠地區(qū)的缺水問題,再結(jié)合第一段中的"solvesometoughchallenges:producingwaterinthedesert,removinggreenhousegasesfromtheairandstoringdangerousgasesmoresafely"可推知,接下來可能會介紹金屬有機(jī)框架在清除溫室氣體、安全儲存危險氣體方面的用途故選B。三答案：1-4BABC解析：1.細(xì)節(jié)理解題。根據(jù)文章第二段TheportablewashingmachinewasinventedbyAshNewlandin2010,whileplanningtoclimbMt.Kilimanjaro.Struckbythelimitedpackingspace,hegotinspirationfromtraditionalwashboardstocreateabagthatcouldbeusedtocleanclothes.Thenhegaveuphiscareerasalawyerandfocusedonperfectingthebag'sdesign.這款便攜式洗衣機(jī)是AshNewland在2010年計劃攀登乞力馬扎羅山時發(fā)明的,由于包裝空間有限,他從傳統(tǒng)的洗衣板上獲得靈感,發(fā)明了一款可以用來洗衣服的包,然后放棄了律師生涯,專注于完善包的設(shè)計?？芍?AshNewland自己外出登山時不方便洗衣服的經(jīng)歷讓他萌生了發(fā)明便攜式洗衣袋,結(jié)合選項(xiàng),故選B。

2.細(xì)節(jié)理解題。根據(jù)文章第三段However,Newlandwasnotsatisfied.Hestillsawadisadvantagewithhisinvention—dirtyclotheshadtobecarriedaroundinaseparatebag!TherecentlyintroducedScrubbaWashPacksolvesthatproblem.然而,Newland并不滿足,他仍然看到了自己發(fā)明的一個缺點(diǎn)—臟衣服必須單獨(dú)裝在袋子里!最近推出的洗滌包解決了這個問題?？芍?他對自己之前的洗衣袋不滿意的地方在于臟衣服和干凈衣服要分開放,這樣就顯得極其的不方便,結(jié)合選項(xiàng),故選A。

3.詞義猜測題。根據(jù)文章第四段Inordertomakethepackactive,dirtyclothesareplacedinsidethebagalongwithtwotothreelitersofwater.Thebagisthenshuttightlytoensureallairissqueezedoutandtheclothesaremassaged(揉搓)forafewminutes.為了使包裝更方便,臟衣服和兩到三公升的水被一起放在袋子里,然后緊緊地關(guān)上袋子,確保所有的空氣都被擠出,衣服被揉搓幾分鐘?？芍?劃線單詞意為:擠壓,結(jié)合選項(xiàng),故選B。

4.推理判斷題。根據(jù)文章最后一段Thebestpartisthatthe99-dollarpackthatwillbeavailableforsalelaterthisyear,onlyweighs300gramsandiscompletelyfoldable,makingiteasytostorewhenit'snotinuse.WiththeScrubbaWashPack,wanderingthroughforeigncitiessearchingforawashingshop,orpayingforwashingmachinesmaysoonbeathingofthepast!最棒的是,今年晚些時候?qū)l(fā)售的99元一包,只重300克,完全可折疊,不使用的時候很容易存放的洗衣包,有了洗滌包,在國外城市四處尋找洗衣店,或者花錢買洗衣機(jī),可能很快就會成為過去!由此可知,被改良的WashPack價格便宜,攜帶方便,使用方便,將在未來受到更多熱愛旅行的人的喜歡,結(jié)合選項(xiàng),故選C。四答案：1-4ADDB

解析：1.推理判斷題。根據(jù)第一段的"Allthosepixels(像素)takeupalotofroomiftheyarestoredonpersonalcomputersorphones,whichisonereasonwhymanypeoplestoretheirimagesinthecloud."(所有這些像素如果存儲在個人電腦或手機(jī)上,會占用很多空間,這也是為什么很多人會將圖像進(jìn)行云存儲的原因之一)可知,人們將照片云存儲的主要目的是節(jié)省存儲空間,故選A。

2.推理判斷題。根據(jù)第二段的"Securityexpertsalsoworryaboutemployeesatcloudstoragecompaniesonpurposeaccessingusers'images."(安全專家還擔(dān)心云存儲公司的員工會故意訪問用戶的圖像)可知,云存儲公司的員工不被專家信任,因?yàn)樗麄兛赡軙悼从脩舻膱D片,故選D。

3.細(xì)節(jié)理解題。根據(jù)第三段的"Wewantedtoseeifwecouldmakeitpossibletoencryptdatawhileusingexistingservices"(我們想看看是否可以在使用現(xiàn)有服務(wù)的同時加密數(shù)據(jù))和"EveryonewantstostaywithGooglePhotosandnothavetoregisteronanewencrypted-imagecloudstorageservice."(每個人都想繼續(xù)使用谷歌Photos,而不必注冊新的加密圖像云存儲服務(wù))可知,ESP的優(yōu)點(diǎn)是可以在原有平臺上對數(shù)據(jù)進(jìn)行加密,故選D。

4.主旨大意題。通讀第四段,尤其是"Toovercomethisproblem,theycreatedatoolthatpreservesblocksofpixelsbutmovesthemaroundtoeffectivelyhidethephotograph"(為了克服這個問題,他們發(fā)明了一種工具,可以保存像素塊,但可以移動它們來有效地隱藏照片)可知,本段主要講的是一種圖像處理技術(shù),故選B。五答案：1-4ADDC解析：1.推理判斷題。根據(jù)第一段中"TheU.N.'sWorldMeteorological(氣象的)Organization,WMO,saidthepredictionsuggestscontinuedwarmingcouldpresentachallengetoclimatechangegoalssetinthe2015ParisAgreement"(聯(lián)合國世界氣象組織(WMO)說,這一預(yù)測表明,持續(xù)變暖可能對2015年《巴黎協(xié)定》中設(shè)定的氣候變化目標(biāo)構(gòu)成挑戰(zhàn)。)可知,據(jù)世界氣象組織稱,持續(xù)變暖的趨勢令人擔(dān)憂。故選A。
