12、he price of a bitcoin topped $900 last week, an enormous surge in value that arrived amidst Congressional hearings where top U.S. financial regulators took a surprisingly optimistic view of digital currency.

Either the highly processed diet causes fatigue or the diet causes obesity, which causes fatigue.“（分数：40.00）(1).【C1】（分数：2.00）A.MeanwhileB.ThereforeC.However D.Moreover解析：解析：上句提到食物中含不健康成分以及营养含量低会

30、有不良影响，而且这一现象司空见惯(No surprises there)，空格后则说 what is more shocking(更令人更加震惊的是)，这与 No sur-prises 语义相反，所以应填入表转折关系的连词。选 C 项 However“然而”。(2).【C2】（分数：2.00）A.everB.shortlyC.onlyD.even 解析：解析：前半句提到垃圾食品饮食方式导致的精力减退效应会长时间持续，主语 what ismore shocking 表示这种效应超出了人们的预期，D 项 even 可用来加强语气，表示“即使，甚至连都”，用于强调 after 引导的时间状语从句。(

31、3).【C3】（分数：2.00）A.regime B.bodyC.scheduleD.lifestyle解析：解析：上文提到垃圾食品饮食方式(a junk food diet)的不良影响，switch 表示“切换”，所以与 a junk food diet 相反的应该是健康的饮食。A 项 regine 表示“养生法，饮食起居”与 diet 语义对应。(4).【C4】（分数：2.00）A.while B.becauseC.ifD.and解析：解析：本句分别说明给两组小白鼠喂食，一组吃未经加工的食物(unprocessed foods)，另一组吃垃圾食品(junk food)。A 项 while“

32、而”表对比关系，符合逻辑。(5).【C5】（分数：2.00）A.servedB.aimed C.meantD.made解析：解析：前面提到一组小白鼠吃未经加工的食物即健康食品，而这一组就要吃“垃圾食品”。据推测，实验人员试图使这组的食物仿制成人类的垃圾食品。B 项 aimed 与 to 搭配表示“努力；试图”。(6).【C6】（分数：2.00）A.caloriesB.nutrients C.proteinsD.vitamins解析：解析：high in sugar, and lower in是对 junk food 的进一步解释。文章第一句表明 junkfood营养含量低(low nutrit

33、ion content)，B 项 nutrients“营养”是同义复现。(7).【C7】（分数：2.00）A.rangedB.differedC.suffered D.judged解析：解析：空格后的 fatigue 为不良后果，空格需填入能与 from 搭配的动词且能表达贬义。C 项suffered from“受的折磨；患病”，符合语义逻辑。(8).【C8】（分数：2.00）A.dullB.diligentC.excitedD.motivated 解析：解析：空格前的 and 表明此空与前面的 active 属于同一范畴的内容，可判断 D 项 motivated 符合。less motiva

34、ted 意为“没那么积极的”。(9).【C9】（分数：2.00）A.generated B.handledC.designedD.created解析：解析：which 指代 tasks(任务)，空格后为宾语 rewards(奖励)。由 even 可知这些吃垃圾食品的小白鼠在所有的任务中都表现不佳。而用于试验的动物通常会养成条件反射，有奖励时会有更好的表现。因此选 A 项 generated“产生”，可以与“奖励”构成合理的动宾关系。(10).【C10】（分数：2.00）A.confusingB.obviousC.popularD.concerning 解析：解析：that 从句提到这些小白鼠结

35、束实验，切换回健康营养的饮食方式长达 9 天后，依然不能扭转体重增加以及慵懒的状态，这说明垃圾食物对健康的影响非常大，故 D 项 concerning“令人担忧”符合研究者对这种现象的反应。(11).【C11】（分数：2.00）A.optionalB.occasional C.significantD.exceptional解析：解析：根据表对比的 while 来判断，if 条件状语从句中的 generally eat a good diet(平时饮食健康)应与 ancase of bad food 存在对比。因此空格处所填的词语语义和 generally 相反并能说明插入语 holiday

36、的性质，故 B 项 occasional“偶尔的”。(12).【C12】（分数：2.00）A.sensitiveB.strangeC.negative D.positive解析：解析：空格前后谈论的是，如果平时饮食健康并且有良好的生活方式，那么偶尔在假期的时候吃不健康的食品会有什么影响。从下一句 But 之后相反的内容可以看出，偶尔吃不健康的食品不会带来太多负面的影响，空格前已经出现 not，故填入 C 项 negative“负面的”，表明“不会带来太多负面的影响”。(13).【C13】（分数：2.00）A.over B.inC.afterD.by解析：解析：定语从句中需填入一个介词与 the

37、 long term 构成的短语作为 eat a poor diet 的时间状语。A 项 over 表示“在期间”，over the long term 表示“在长期内”，该句意为对于在长期内饮食不健康的人而言。(14).【C14】（分数：2.00）A.defined asB.associated with C.combined withD.assisted in解析：解析：长期饮食不健康的人很有可能变得懒惰、疲劳(lazy and fatigued)、体重增加(gain-ing weight)，还要承担因此而产生的后果(consequences)。此空格需填入的短语与 being over-

38、weight 构成consequences 的后置定语，说明两者的关系。B 项 associated with“与有关”，表明饮食不健康与超重有关。(15).【C15】（分数：2.00）A.onB.offC.to D.in解析：解析：此处填入与 switching(转换)搭配的介词，宾语是 a healthy diet，与上一段第一句switching these rats back onto a nutritious diet 语义对应。switch to 表示“转变成”符合语义逻辑。故选 C 项 to。(16).【C16】（分数：2.00）A.sufficient B.usefulC.co

39、mpetentD.efficient解析：解析：本段开头提到研究中观察到那些吃了 6 个月的垃圾食品的小白鼠，切换回健康营养的饮食方式 9 天后，仍然不能扭转体重增加以及慵懒的状态。本句与上文语义呼应，阐述小白鼠实验中得出的结论：短期内不能逆转食用大量垃圾食品导致的副作用(reverse any of the side ef-fects)，因为短期内给身体补充健康的食物是不够的，故选择 A 项 sufficient“足够的”。(17).【C17】（分数：2.00）A.courtesyB.discipline C.regulationD.confidence解析：解析：根据常识可知，如果摄入过多

40、的脂肪和糖分，又缺乏运动便会超重。因此要控制体重必须节制这些食物，少吃多运动，而超重者之所以超重是因为他们自控能力差。因此 B 项 disci-pline 为答案，lacking discipline 表示“缺乏自制力”。(18).【C18】（分数：2.00）A.testB.expressC.interpret D.demonstrate解析：解析：本句继续讨论超重者超重的原因和人们对超重的看法：人们变胖的原因是他们很懒，指出这种说法是错误的。此空格的宾语是 our results，所需词语要能与 as 搭配，且能说明宾语。 interpret sth as sth“把理解为”符合语义逻辑，故

41、选 C 项。(19).【C19】（分数：2.00）A.prescribedB.provedC.portrayed D.argued解析：解析：the idea 指的是其后的 that 从句“人们变胖的原因是他们很懒”，空格所需词语应能体现这种 idea 和媒体的关系。公众的认识通常会有媒体影响，而这种观点往往会被媒体大肆渲染。C 项portrayed“描绘”符合语义。(20).【C20】（分数：2.00）A.better thanB.other thanC.sooner thanD.rather than 解析：解析：空格前提到，饮食诱发的肥胖是懒惰的原因(cause)，换句话说，肥胖不是懒惰

42、的结果(effect)。D 项 rather than“而不是”代入句中逻辑正确。The price of a bitcoin topped $900 last week, an enormous surge in value that arrived amidst Congressional hearings where top U.S. financial regulators took a surprisingly optimistic view of digital currency. Just 10 months ago, a bitcoin only sold for $13. T
