So the message is,【B20】_on with the crosswords.（分数：40.00）(1).【B1】（分数：2.00）A.tinyB.smallC.dramatic D.enormous解析：解析：考查形容词辨析。根据前文“一股抗衰老的研究热潮正达到顶峰”，可以推知大脑训练游戏是迅速兴起的。因此 Cdramatic“戏剧的，引人注目的”符合文意，为

26、最佳选项。tiny“微小”；small“小的，少的”；enormous“巨大的，庞大的”，强调事物体积的巨大，三项均不符合题意。(2).【B2】（分数：2.00）A.effective B.affectiveC.efficientD.constructive解析：解析：考查形容词辨析。空格处所在句意为：不过一天一张字谜游戏到底有多大的_呢?前文阐述了大脑训练游戏迅速兴起，后文介绍了针对游戏效果的实验。据此推知，空格处应该是对于游戏的效果表示怀疑。Aeffective“有效的，起作用的”，符合文意，为最佳选项。affective“情感的”；efficient“有效率的”；constructive

27、“建设性的”，均不符合题意。(3).【B3】（分数：2.00）A.checkB.figureC.find D.pick解析：解析：考查动词短语辨析。前文阐述了一个现象，后文介绍了针对游戏效果的实验。据此可以推知，这些人希望通过研究以查明、探究这个现象。find out 意为“找出，查明”，符合文意。check out 意为“检查，结账离开”；figure out 意为“算出，想出”；pick out 意为“挑选出，辨别出”，均不符合题意。故答案为 Cfind。(4).【B4】（分数：2.00）A.withB.by C.inD.as解析：解析：考查介词辨析。根据语境可知，后文介绍的是实验研究的方

28、式，故正确答案为 Bby。其他三项均不符合题意。(5).【B5】（分数：2.00）A.rate B.anticipateC.declareD.assert解析：解析：考查动词辨析。空格处所在句意为：参与者被要求_自己参加某活动的频繁程度。后文主要阐述了活动的覆盖范围，没有其他实验结果，因此可以推知，此处应该为“要求参与者评价自己参加某活动的频繁程度”，因此 Arate“评价，估计”符合文意，为最佳选项。anticipate“期望，预期”；declare“宣布，声明”；assert“声称，断言”，均不符合题意。(6).【B6】（分数：2.00）A.sustainingB.transforming

29、C.recedingD.stimulating 解析：解析：考查形容词辨析。空格处所在句意为：参与者要求对自己参加认知_活动的频繁程度进行评价。后文举例提到“读报、读书玩象棋等游戏”，根据语境可知，这些均为认知激发类的活动，因此 Dstimulating“有激发性的，刺激的”符合文意，为正确选项。sustaining“持续的”：transforming“转变的，转化的”；receding“减弱的”，均不符合题意。(7).【B7】（分数：2.00）A.settingB.playing C.arrangingD.making解析：解析：考查固定搭配。play chess 意为“玩象棋”，为固定搭配

30、。因此答案为 Bplaying。(8).【B8】（分数：2.00）A.watchingB.viewingC.sightseeingD.visiting 解析：解析：考查动词辨析。根据语境可知，此处意为“参观博物馆”，因此 Dvisiting“参观，拜访”符合文意，为正确答案。watching“观看，监视”，多用于观看比赛等；viewing“观察”，含有边看边思考的含义；sightseeing“观光”，多指游览风景，均不符合题意。(9).【B9】（分数：2.00）A.casualB.successiveC.frequent D.continuous解析：解析：考查形容词辨析。前面提到，“参与者被

31、要求评价自己参加认知激发活动的频繁程度”，并以此来做研究。据此推知，频繁的活动会有某种影响。因此答案为 Cfrequent“频繁的，惯常的”。casual“临时的，偶然的”；successive“接替的，继承的”；continuous“持续的”，均不符合文意。(10).【B10】（分数：2.00）A.mental B.physicalC.spiritualD.energetic解析：解析：考查形容词辨析。根据语境可知，此处意为“智力衰退”，因此 Amental“精神的，脑力的”符合题意，为最佳选项。physical“身体的”；spiritual“心灵的”；energetic“精力旺盛的”，均不

32、符合题意。(11).【B11】（分数：2.00）A.obstacleB.inclinationC.limitationD.impairment 解析：解析：考查名词辨析。第二段开头介绍：它们的研究对象是一组智力正常的人。据此推知此处指“无认知障碍者”，impairment 意为“伤残，损伤”，cognitive impairment 意为“认知障碍”，符合文意。故答案为 D。obstacle“障碍”，多指具体的妨碍物；inclination“趋势，倾向”；limitation“限度，限制”，三项均不符合题意。(12).【B12】（分数：2.00）A.consecutiveB.subsequen

35、析：解析：考查动词辨析。根据语境可知，此处强调损害由少到多的积累，因此只有Baccumulate“累积，积聚”符合题意。amass“收集，堆积；积聚(尤指财富)”；collect“收集，募捐”；gather“聚集，集合”，均不符合题意。(16).【B16】（分数：2.00）A.hold B.careC.chargeD.up解析：解析：考查动词短语辨析。take hold 意为“生根，固定下来”；take care 意为“小心，注意”；take charge 意为“掌管，负责”；take up 意为“从事，占用”。根据语境可知，此处指疾病产生，因此只有 take hold 符合文意故选 Ahol

36、d。(17).【B17】（分数：2.00）A.slightB.mildC.abundantD.rapid 解析：解析：考查形容词辨析。前文提到：当疾病最后开始发作时，带来的损害比原来的更多。据此可以推知，此处应指“更快的认知功能的减退”。因此答案为 Drapid“迅速的”。slight“轻微的”；mild“温和的”；abundant“大量的，丰富的”，均不符合题意。(18).【B18】（分数：2.00）A.untilB.though C.unlessD.if解析：解析：考查逻辑关系。空格前阐述：当疾病最后开始发作时，带来的损害比原来的更多。空格后阐述：这并不是令人绝望的消息。据此推知，前后为转

37、折关系，因此正确答案为 Bthough“尽管，虽然”。其他三项均不符合题意。(19).【B19】（分数：2.00）A.reduced B.degradedC.declinedD.increased解析：解析：考查上下文语义及动词辨析。上文提到“这并不是令人绝望的消息”，下文阐述“他们的健康时间延长了”。据此可以推知，痴呆儿的病痛时间会因此“减少”。因此 Areduced“减少，降低”为正确答案。degraded“削减，降级”；decline“下降，衰退”；increase“增加，提高”，均不符合题意。(20).【B20】（分数：2.00）A.letB.putC.workD.carry 解析：解

38、析：考查动词短语辨析。根据语境可知，此处表达的意义为“填字游戏应该继续下去”，carry on 意为“继续进行”，符合题意。故正确答案为 D。carry。let on“泄露，假装”；put on“穿上，上演，增加”：work on“对起作用，影响”，均不符合题意。The Earth s daily clock, measured in a single revolution, is twenty-four hours. The human clock,【B1】_, is actually about twenty-five hours. That s 【B2】_ scientists who

44、）(1).【B1】（分数：2.00）A.however B.otherwiseC.likewiseD.therefore解析：解析：考查逻辑关系。此处句意为“以一次单独的旋转来测量，地球每天的时钟是 24 小时。_，人类的时钟实际大约是 25 小时。”根据上下文的意思以及提示词 actually，可以判断出本句与上句是转折关系。所以，正确答案是 Ahowever。otherwise“否则，不然”，likewise“照样，而且”，therefore“总之，因此”，均不符合题意。(2).【B2】（分数：2.00）A.theB.what C.becauseD.many解析：解析：考查语法知识。句子的

45、谓语是 is，空格处缺的必然是一个连词或关系词。Bwhat 是关系代词，在从句中作表语，符合题意。what 引导的这个表语从句比较复杂：who study sleep 是定语从句，修饰 scientists；定语从句 who live for several weeksday or night 修饰先行词 humansubjects。故Bwhat 为正确答案。because 是连词，表示原因。其他两项明显不符合题意，故排除。(3).【B3】（分数：2.00）A.ideaB.feelingC.sense D.judgment解析：解析：考查名词辨析+固定搭配。此处句意为“这些受试者在观察室里住几

46、个星期，_白天和黑夜”。四个选项中可以和 with no_of 搭配的只有 idea 和 sense。idea“念头，想法，主意”，sense“由刺激产生的感觉或知觉”。根据上下文，Csense 符合题意，为正确答案。feeling 多指由感情、情绪或欲望引起的情绪状态，judgment“判断，审判”，均不符合题意，故排除。(4).【B4】（分数：2.00）A.come up againstB.come down toC.come up with D.come up to解析：解析：考查短语辨析。此处句意为“睡眠研究者们还_了其他令人惊讶的发现”。come up against 指突然或意外碰

47、到困难或反对等，come down to“归结为”，come up with“提出，拿出，发现”，come up to“比得上，达到”。根据意思，Ccome up with 符合题意，为正确答案。(5).【B5】（分数：2.00）A.withB.like C.unlikeD.as解析：解析：考查介词辨析。空格处的介词体现的是 sleeping 和 eating and breathing 的关系。从上下文得知“睡眠是最重要的生命过程”。根据我们的常识，吃饭、呼吸和睡眠一样重要。故 Blike 符合题意，为正确答案。with“和，跟；随着；关于”，unlike“不像”，as“作为，以的身份”，均不符合题意。(6).【B6】（分数：2.00）A.little B.muchC.fewD.long解析：解析：考查上下文语义。此处句意为“然而一些人几乎从来不睡觉，一天_15 分钟就可以了”。根据前文的提示 almost never sleep，我们可直接选出正确答案 Alittle。其他三项均不符合题意，故排除。(7).【B7】（分数：2.00）A.probeB.investigationC.resea
