25、.（分数：40.00）(1).【1】（分数：2.00）A.allegationB.alternation C.allocationD.alternative解析：解析：allegation 意为“主张，断言”；allocation 意为“分配，安置”，均与文章的意思不符。alternation意为“交替，轮换”，alternative 是 alternation的形容词形式，此处应填一个名词，所以 B是正确答案。(2).【2】（分数：2.00）A.overB.ofC.with D.in解析：解析：本题考查介词搭配。coincide with 为固定词组，指“一致，相符合”，此处指“通常睡眠时间
26、和黑夜时间相吻合”。而 A、B、D 三项不能与 coincide搭配，故选 C。(3).【3】（分数：2.00）A.thinkB.considerC.regardD.concern 解析：解析：本题考查名词的辨析。句子的意思是“我们目前所关心的是”，只有 D项 concern有“关心，关注”的意思，所以正确答案是 D项。(4).【4】（分数：2.00）A.roundB.circleC.periodD.cycle 解析：解析：本题考查名词的辨析。cycle 与前文保持一致，意为“循环，周期”，此处指“我们现在关心在何等程度上循环可以改善”。round 意为“圆，圆形物”；circle 意为“圆”
27、；period 意为“一段时间”，所以 D项为正确答案。(5).【5】（分数：2.00）A.forB.thatC.Which D.as解析：解析：本题考查介词+关系代词引导的定语从句的用法。关系代词在定语从句中作介词宾语时，从句常由介词+关系代词引导，如：The school in which he once studied isvery famous本题的句子结构是；The ease(主语)+with(介词+关系代词引导的定语从句)+is，所以正确答案为 C项。(6).【6】（分数：2.00）A.matter B.troubleC.difficultyD.problem解析：解析：本题考查名
28、词词义辨析。a matter of 为固定词组，意为“(涉及的)问题”。trouble 意为“麻烦”；difficulty 指“困境”；problem 指“难题，困难”，所以选 A。(7).【7】（分数：2.00）A.reacts toB.calls for C.invitesD.asks解析：解析：本题考查对动词词义的掌握。call for 意为“需要，值得”，此处指“自动化需要机器昼夜不停地工作”。react to 意为“反应”；invite 意为“邀请”；ask 意为“询问”，所以选 B。(8).【8】（分数：2.00）A.requestsB.demandsC.spendsD.takes
29、 解析：解析：本题考查对固定搭配的掌握。It takes some time to do sth为固定句型；而 A、B、C 三项在句中不能以 it作为形式主语，故 D项为正确答案。(9).【9】（分数：2.00）A.regularB.reversed C.returnedD.former解析：解析：本题是形容词辨析题。reversed 表示“反转的，颠倒的”，此处指“通常人们要花五天到一周的时间来适应一个相反的循环”。regular 意为“有规律的”；returned 意为“退同的”；former意为“早期的”，所以正确答案是 B项。(10).【10】（分数：2.00）A.during B.a
30、fterC.ohD.with解析：解析：本题考查介词的用法。句子的意思是说在白天睡觉晚上工作，此处应该选择 during，因为during the day表示在这一天的时间里，表示持续性的一天，所以选 A。若表示具体的星期、日、月，应该用 on，比如：on that day，on Friday，on March；表示年用 in，比如：in 1999。但是如果年月日一起就用 on，比如：on the January 1st，1999。(11).【11】（分数：2.00）A.In comparisonB.In a wordC.Unfortunately D.Therefore解析：解析：本题考查对
31、上下文的理解。上文提到“颠倒作息时间大约需要五天到一个星期”，而后文又说“在工厂里这种轮班工作经常是每周一换的”。工人们刚调整过来的作息时间又得换回去，这显然是“不幸地”。in comparison 意为“比较”；in a word 意为“总之”；therefore 意为“因此，所以”，此三项意思上不符合原文，所以选 C。(12).【12】（分数：2.00）A.meanB.meaningC.meantD.means 解析：解析：本题考查谓语动词。此句的句子结构是 This(主语)+谓语+that，主语是 this，而且整篇文章用的都是一般现在时，所以这里就只能选择 means，正确答案是 D项
32、。(13).【13】（分数：2.00）A.than B.thenC.whenD.as解析：解析：本题为语法题，考查连词固定搭配的用法。no soonerthan表示“一就”。此处指“这就意味着他刚适应一个循环，又变成了另一个循环”，而 B、C、D 三项不能与 no sooner搭配，所以正确答案是 A项。(14).【14】（分数：2.00）A.asB.whileC.so that D.though解析：解析：本题考查对上下文的理解及连词的用法。前后文为因果关系，此处指“所以他的睡眠、工作效率都不高”，所以选 so that。(15).【15】（分数：2.00）A.happilyB.easily
33、C.goodD.efficiently 解析：解析：本题考查对上下文的理解及副词的理解和运用。此处意为“作息时间经常性的颠倒当然会降低工作和睡眠的效率”；A、B、C 三项在意思上不符合原文，故 D项为正确答案。(16).【16】（分数：2.00）A.nicerB.longer C.betterD.shorter解析：解析：本题考查对上下文的理解。这里的 a month相对于前面的 a week当然是较长一点儿，所以选 B。(17).【17】（分数：2.00）A.However B.SimilarlyC.In shortD.So解析：解析：本题考查对上下文的理解。前文提到了较长的转换期，这相对于
34、一个星期来说会好一些，但它同样有不足之处。前后为转折关系。而选项 B、C、D 都不表示转折关系，所以选 A。(18).【18】（分数：2.00）A.favouriteB.temporaryC.normal D.new解析：解析：本题考查形容词的用法。normal 为“正常的”，此处指“在周末回到他们原来那种白天工作晚上睡觉的常规作息时间”。favourite 意为“喜爱的”，temporary 意为“短暂的，暂时的”均与原文意思不符，而且这句话里有 go back to，从意思上理解不能选 D，所以选 C。(19).【19】（分数：2.00）A.tendencyB.adaptation C.r
35、eturnD.change解析：解析：本题考查名词固定搭配和对句子的理解。adaptation(to)指“(对的)适应性”，在文中提及人类作息时间转换的适应性时，用的都是 adapt；而 tendency意为“倾向，趋势”，所以选 B。(20).【20】（分数：2.00）A.habit B.preferenceC.sleepD.wakefulness解析：解析：本题是名词辨析题。habit 此处指作息习惯。preference 意为“偏爱”；wakefulness 意为“醒着”，意思上不符合原文，所以 A项为正确答案。（清华大学 2007年试题） Sea rise as a consequen
