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

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

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
