本句是讨论实验发现与现实应用之间的关系，尽管在实验中双语者表现更好，这种表现能否迁移至现实工作或生活中仍未可知。translateinto可以表示“把(思想、情感等)用另一种(尤指更具体的)形式表现出来”，符合上下文语义，故D为答案。develop“发展”和integrate“融合”显然不符合语境，排除；convert“转变”有一定干扰性，但该词表示的是“改变事物的形式或用途”，并不符合原文，排除。47．【C18】A．purposeB．undertakingC．approachD．environment正确答案：D解析：名词辨析题。句意同上。利用此处由or连接的并列结构进行分析，连词or之前为intheworkplace，是一种条件和场景，因此本题所选择的名词应该表示“环境，情况”等含义，故选environment。purpose“目的”，undertaking“事业”和approach“方法”均不能与intheworkplace构成并列关系，因此均排除。48．【C19】A．promiseB．predictC．provideD．prove正确答案：C解析：动词辨析题。句意为：唯一在现实应用中初步得到证实的可能就是，多语使用对老年痴呆症患者有益。此处文章是在讨论双语使用的现实益处，而不是讨论其未来的可能，因此首先排除promise“承诺”和predict“预测”；这里是阐述实验研究以外的现实情况，因此prove“证实”不合上下文语境，也应排除。provide“提供，带来”符合原文语义，并可与介词to搭配，故为答案。49．【C20】A．symptomsB．declineC．incidencesD．spread正确答案：A解析：名词辨析题。句意为：双语使用者最多可比单语使用者晚四年发病。承接上一句，本句继续讨论多语使用给老年痴呆症患者带来的益处。再根据后置定语ofthedisease，之前的动词show，以及句中“晚四年”等信息，可知此处应选择symptoms“症状”。decline“衰退”、incidences“发生率”、spread“传播”均不合原文语境，故均可排除。PARTIVGRAMMAR&VOCABULARY(15MIN)Directions:Therearethirtysentencesinthissection.BeneatheachsentencetherearefourwordsorphrasesmarkedA,B,CandD.Chooseonewordorphrasethatbestcompletesthesentence.50．WhoisitthathasmadeMike______heisnow?A．whoB．howC．whatD．whom正确答案：C解析：宾语从句题。what引导宾语从句，表示“……的人”，相当于thepersonthat，故答案为C。51．Barely______attheairportwhenthepolicearrestedhim.A．didhearriveB．hadhearrivedC．hearrivedD．hehadarrived正确答案：B解析：固定结构题。barely…when…为固定结构，意为“刚……就……”，barely表示否定意义，放在句首时，要用部分倒装；并且在此考题中从句用过去时态，主句动作发生在从句之前，故用过去完成时态，答案为B。52．Thepresident’sresidenceisreportedinthenationalnewspaper______lastnight.A．beingbrokenintoB．tohavebeenbrokenintoC．havingbeenbrokenintoD．brokeinto正确答案：B解析：不定式用法题。此处考查不定式作主语补足语，用于对主语进行补充说明，故答案为B。53．WhichofthefollowingsentencesisaCOMMAND?A．Becarefulwhencrossingthestreet.B．Keepoffthegrass.C．Don’tbenervous.D．Dogivemyregardstoyourparents.正确答案：B解析：句子功能题。Becarefulwhencrossingthestreet．意为“过马路的时候要小心。”，表示警告；Keepoffthegrass．意为“请勿践踏草地。”，表示命令；Don’tbenervous．“不要紧张。”，表示劝慰；Dogivemyregardstoyourparents．意为“一定代我向你父母问好。”，表示问候、致意。故答案为B。54．______inthedark,hisheadbumpedagainstthewall.A．WhenhewaswalkingB．WhenwalkingC．WalkingD．Whilewalking正确答案：A解析：状语从句题。各选项中的walk和主句主语hishead没有任何逻辑关系，因此在此处不能使用walk的非谓语形式，也不能使用while+-ing形式作状语，否则就形成了垂悬结构。因此，此处只能使用when引导的状语从句，答案为A。55．______,butIstilldon’tlikehim.A．CleverthoughheisB．CleverasheisC．CleverhemaybeD．Whetherheiscleverornot正确答案：C解析：状语从句题。此句可能误选A和B，但A和B作让步状语从句时，后面不接but，故选C。56．Jimcanbarelyboilanegg,______cookdinner.A．muchmoreB．muchlessC．stillmoreD．morethan正确答案：B解析：副词用法题。muchmore和muchless这两种表达法都有“更加”的意思。muchmore用于肯定句，表示程度加强；muchless引导的分句表示一种追加的否定，只能用于否定句中，表示程度减少。结合前半句语义，后半句是程度的减少，故选B。C和D均不符合句意，排除。57．Jane______myletter;otherwiseshewouldhaverepliedbeforenow.A．oughttohavereceivedB．hasreceivedC．couldn’thavereceivedD．hadn’treceived正确答案：C解析：情态动词题。couldn’thave+过去分词，表示对已发生情况的否定推测，意为“一定没……”。结合后半句语义，可知Jane并没有收到信，故C正确。58．Invain______togetthemachinesoldyesterday.A．hetriedB．hadhetriedC．hehadtriedD．didhetry正确答案：D解析：倒装结构题。invain意为“徒劳地；白费；无效”，表否定意义，放在句首要用部分倒装，此处就是把助动词提到主语前面，且时间副词是yesterday，故用一般过去时，所以did提到he之前，后面跟动词原形。故D为答案。59．Itisdesiredthathisorder______assoonaspossible.A．willbecarriedoutB．shouldbecarriedoutC．mustbecarriedoutD．wouldbecarriedout正确答案：B解析：虚拟语气题。在Itisdesired／suggested／ordered／essential／necessary／important等词后的从句中用“should+动词原形”，故答案为B。60．Idon’tbelieveshewillgetaraiseinpay,______?A．doIB．willsheC．won’tsheD．doesn’tshe正确答案：B解析：
