29、20 as it will on a plane.（分数：40.00）A.detectionB.destructionC.desperationD.destination解析：解析 文章主题与travel相关，destination“目的地”能与之相对应，符合句意。A.confusedB.mixedC.complicatedD.involved解析：解析 complicated与involved都有“复杂的”含义，但complicated一般指的是事情复杂得难以解释或解决，involved强调的是关系的错综复杂。此句主语transporting pets on flights是一种做法，故用c
30、omplicated最为合适。A.hardlyB.significantlyC.highlyD.normally解析：解析 hardly“几乎不”，与上文的more expensive相矛盾。significantly“大大地”，符合语境；highly也是程度副词，具有一定的干扰性，但highly表示“高度地，非常”，不能修饰raised the fees“提高费用”。A.collectB.costC.chargeD.pay解析：解析 that引导的定语从句修饰the fees，其中they指carriers，即航空公司。四个选项都能表示与钱有关的行为，但又各有区别。collect money
31、指的是“筹款”，但collect不与fee搭配；cost“花费，付出代价”和pay“付款”，与句意相反；charge the fee是习惯用法，意为“收费”，为正确答案。A.exhibitingB.exertingC.executingD.exceeding解析：解析 由or in some cases可知，需填入的词与空格前的matching“相等”是递进关系，故exceeding“超过”符合语境。A.varyB.modifyC.convertD.shift解析：解析 四个选项都有“改变”的意思，此句指“费用的变化”。vary“变化”；modify“修改，变更”，一般指一些文字的修改；con
32、vert多指事物外表、用途、性质的“转换，转变”；shift“改变，转移”，一般指位置或方向的改变。由此可知vary最符合句意。A.relateB.evolveC.involveD.include解析：解析 根据空格前后文的关系进行判断，checked baggage会带来extra handling“额外的费用”，所以involve“涉及”为最佳答案。A.amazingB.confusingC.promisingD.pressing解析：解析 下文提到宠物丢失、受伤或死亡的事件，由此可判断宠物的安全是一个迫切需要解决的问题，故选pressing“迫切的”。A.arisenB.risenC.d
33、escendedD.raised解析：解析 由后文的Thirty-nine.last year，.22 two years ago可知动物受到伤害的事件在增多。arise“出现”，与句意不符；rise“升高，增加”，符合句意；descend“下降”，与句意相反；raise“举起”，一般是及物动词，放在此不符合语法规则。A.commercialB.privateC.tradingD.comprehensive解析：解析 由全文第1句和空格前的while flying aboard可知这里谈论的是大众和宠物的旅行方式，commercial“商业的”，与jets搭配意为“公务机”，符合语境。A.If
34、B.SinceC.WhileD.As解析：解析 从句说明“只占很小的比例”，主句表示“暴露了宠物们旅行而临的危险”，由此判断句子是让步状语从句，所以选While“尽管”。A.supposeB.anticipateC.expectD.judge解析：解析 suppose“猜想”；anticipate“预料”；expect指的是对可能发生或出现的某事或某人的期待；judge“判断”。空格后的词是risks“风险”，选择anticipate最为合适，意为“预料风险”。A.instantB.immediateC.rapidD.sudden解析：解析 instant“瞬间的，立刻的”；immediate
35、“立即的”，形容动作迅速；rapid“迅速的”修饰速度或动作；sudden“突然的”。只有sudden能与illness搭配，而且结合上下文分析，既然宠物是在飞行途中患病，应该是突发疾病，故选sudden。A.fatalitiesB.facilitiesC.facultiesD.fantasies解析：解析 由上文的dangers，risks和illness可知这一段谈论的是动物在旅行中而临的风险，所以fatalities“死亡”符合语境，也与第2段的died相呼应。A.cancelsB.obstructsC.bansD.deletes解析：解析 上文提到一些宠物容易出现问题，由此可判断正是这
36、个原因，Delta会“禁止”一些宠物品种上机，所以选ban“禁止”。A.friendlyB.kindC.intimateD.lively解析：解析 friendly除了常用的意思“友好的”之外，接在名词后还表示“对有利的，对无害的”等含义，pet friendly意为“对宠物有利的”。A.interactionB.returnC.responseD.feedback解析：解析 interaction“互动”，feedback“反馈”，这两个词一般都不与in.to搭配。return“返还”，in return to表示“作为对的回报”，in response to意为“作为对的反应”。上文提到的
37、是问题，下文是针对问题采取的措施，所以in response to符合句意。A.UsuallyB.GenerallyC.ObviouslyD.Previously解析：解析 空格前的句子意思为“首次允许宠物进入乘客舱”，这是一种新的做法，空格后的句子表明“只是将宠物作为行李进行托运”，并采用过去完成时had transported，可知是以前的做法，所以选previously“以前”。A.smashB.smoothC.sketchD.splash解析：解析 空格处动作发出的对象是the process“过程”，smooth作动词时表示“使光滑，使顺利”，符合语境，意为“使旅程顺利”。smash
38、“粉碎”；sketch“概述，作草图”；splash“溅起”。A.shockB.liberationC.substitutionD.vibration解析：解析 shock“震动”；liberation“解放”；substitution“代替”；vibration“震动”。空格前的关键词组是the floor of the car, liberation和substitution与之搭配不当，可排除。shock和vibration都有“震动”的意思，但shock指的是剧烈的震动、猛烈的撞击，与语境不符，故选vibration。Summer is an ideal time for junior

44、A.nearlyB.perfectlyC.highlyD.hardly解析：解析 文章一开头就建议学生在夏季开始写大学入学论文。这一句分析了选择在夏季写的原因，由less hurried可知夏季比较清闲，暗示之后的秋季会比较忙，压力比较大，故选highly pressured。A.remedyB.reflectC.reserveD.resign解析：解析 所需词与think是并列关系，故应填入与think“思考”相对应的词，只有reflect“深思”符合语境。A.advantageB.gainC.favorD.profit解析：解析 to the best advantage是习惯用法，表示“
45、充分利用；达到最佳程度”。A.heartB.mindC.soulD.thought解析：解析 keep in mind是固定搭配，意为“记住”。A.DiscriminationB.DistributionsC.DistinctionsD.Distractions解析：解析 discrimination“歧视；辨别力”；distribution“分布；分配”；distinction“区别”；distraction“使人分心的事；娱乐，消遣”。TV and Internet surfing是对空格所填词的举例说明，显然，看电视和上网是娱乐消遣，所以distraction符合语境。下一句的diversions也提示了此处的答案。A.motivationB.awarenessC.inspirationD.insight解析：解析 motivation“动机”；awareness“意识”；inspiration“灵感”；insight“洞察力”。由下文的thought bubbling up(不断涌现的想法)可知此处应该是表“灵感”的词，inspiration合适，选C。A.scheduleB.program
