本文是一篇說明文，說明了睡眠缺失對人們大腦的影響，以及駕駛員如果缺乏睡眠可能導致的嚴重后果。【難句分析】showthattheisnegativelyaffectedbydeprivationbecausepatternsofelectricalandchemicalthatoccursleepandthebraincannotfunction分析：本句是一個復合句。第一個引導賓語從句，在從句中不作句子成分；第二個hat引定語從句，在從句中作主語，指代先行詞patternsofandchemicalactivity；引原因狀語從句。譯文：研究表明大腦會因為睡眠不足而受到負面的影響，因為在睡眠期間發(fā)生的某些電子和化活動被打斷，大腦不能正常地運轉(zhuǎn)。．underlined“deprivation”infirstparagraphisclosestto________.ABlossC．discomfortD．答案與解析B考詞義猜測。根據(jù)第一段第二“However,manyadultsdogeteighthoursofsleepeachnight”可知，許多年人睡眠不足，由此可推知是缺失的含義，這與本段最后一“Asignificantnumberofpeopleworkworklonghours,orortlag呼，故選B。．Thementionsalloffollowingofdeprivation________.AjetlagB．workhoursC．boringDworking答案與解析考細節(jié)理解。根據(jù)第一段最后一“significantofpeopleworknight,nghours,orsufferfromsleeplessnesslag可知，睡眠缺失的原因很多，但不包括工作枯燥故選。3

．ThepurposeofthestudyinParagraphwastodetermine________.AhourscansurvivewithoutsleepBhowreactsleepC．inbrainactivitysleepD．effectsofsleepdeprivationonbrainactivity答案與解析D考查推理判斷。根據(jù)第二段第一“showthatthebrainisnegativelyaffectedbysleepcertainofelectricalandactivitysleepbraincannotfunctionnormally并結(jié)合本段的內(nèi)容可推知，本段主要論述的是睡缺失對大腦的影響，故選D。．WhydoesthebloodalcoholinParagraph3?AToshowsleepdeprivationbloodB．ToshowthatsleephasthedangerouseffectsasbeingC．suggestthatsleep-deprivedaretodrink.D．a(chǎn)rgueagainstraisinglegallimitdrunkdriving.答案與解析B考推理判斷。根據(jù)文章第三段第二“Instudyofdrivers,thatdeprivationhadeffectsasbeingdrunk可推知提血液中酒精濃度的例子是為了證明之前的結(jié)論，即：睡眠缺失和飲酒在駕駛中的危害同樣嚴重，故選B。II.選（湖北省七市聯(lián)考knowIfyou'retheofteens,youbelaughingallknowIntruth,mightknowenoughsleep,whentosleepwhy.Justfocusondietsandforneedtosleepnecessarytophysicalapsychologicalhealth.“Goodsleepissleepislongenoughtoallowyourbrainremovethesideeffectsofdaytimebrainactivity.Consistentbedkeytosleepareathemostattractivesocial“gathering”placeisontheirdigitaldevices.Ideally,shouldavoidlightforanhourbeforemediathatrequiresarepoweringuptheirbodiesshouldbedownforthenight.contributingtotooandfailingpeoplelearnedhowsleep.Overpoorsleepleadstoinmood.Significantly,IadultstrugglingwithsleepallofthemsaysleepinIrecommendsleepOtherwise,solvesafety4

本句位于段落末尾句，要么是段落主題句或是承上啟下的過渡句。段落首句提出問題，第二句介紹父母的反應第四句紹孩子們的情況可推知空所在句是提出本段的觀點也就對首句問題的回答，所以選G。答案與解析A項中的代詞they指前句中的Consistentbedtimesandwakeuptimes前后意思連貫，所以選A項。．答案與解析：CC項的是空前digitaldevices的舉，同時句中的light空處后句再次出現(xiàn)，這是同義復現(xiàn)。C接觸來自我們屏幕的藍光推遲了睡與空后理想情況下，我應該在睡前至少半小時避免藍光構(gòu)了因果關(guān)系所以選項。．案與解析：B

空后列舉了造成睡眠不好的幾個方面，由此可見此段主要介紹導致睡眠不好的主要表現(xiàn)形式，所以B項的Goingtobedtoo睡覺太)也之一，所以選B項答與解析：E項的contributesto與句中“l(fā)eadsto是相同的表達同一更好體現(xiàn)二之間的連貫，所以選項Ⅲ語填（江西五校第一次聯(lián)考TheWorldhasanappealscientists,drugmanufacturersandwantswork__1__(develop)drugsfight12bacteria.bacteriatoantibiotic(抗素sounusuallythatthe12bacteriahavebeengivenaspecialname“superbug．TheUnitedNationsagency12superbugsthreattohuman__4__(healthy).Itsaidthey__5__abilityturntreatablekillers.TheWHOsayssuperbugsalsoalonggenetic__6__helpsbacteriabecomeresistanttodrugtreatment.riePauleKienyistheAssistantDirectorGeneralatWHO.Shesaid,“Antibioticresistanceisgrowingandwearerunningout__7__treatmentoptions.”urgedgovernmentstogivedrugcompaniesreasonstodevelopnewtreatments.leav
