If your child 18 has more homework than this, you may want to check 19 other parents and then talk to the teacher about 20 assignments.（分数：40.00）A.veryB.exactC.rightD.usual解析：解析 very修饰名词，表示强调，that very evening指的是“正是那个晚上”。A.officialsB.parentsC.expertsD.schools解析：解析 前半句提到In the race.standar

29、ds(为了提高教育水平)，推测提高教育水平应是学校的目的，故选D。A.AlsoB.EvenC.ThenD.However解析：解析 根据前一句中“学校把大量的书扔给学生(即布置很多学习任务)”，本句表达的应该是“就连(even)小学生都抱怨”，这是对上文的递进说明。A.fatigueB.confusionC.dutyD.puzzle解析：解析 根据上文的burning the late-night oil(熬到深夜)和throwing the books at kids(把大量的书扔给学生)这样的表达，推断作业太多，从而造成“疲惫”(fatigue)。confusion“困惑”；duty“责任

30、”；puzzle“难题”。A.thereB.weC.theyD.it解析：解析 it may be hard (to do sth.)为习惯表达，意为“做某事可能有难度”，it为形式主语。A.viaB.underC.byD.for解析：解析 此处亦为固定表达，by doing sth.，you may.“通过做某事，你会”。A.questionsB.answersC.standardsD.rules解析：解析 examine answers为习惯动宾搭配，意思是“检查答案”。A.offB.withoutC.beyondD.from解析：解析 keep sb. from doing sth.为习

31、惯搭配，指“使某人不能做某事”。A.singleB.pieceC.pageD.other解析：解析 “every single+n.”中的single起强调作用，表示“每一个”；piece和page后接名词前要先加of；every other的意思是“每隔”，在此处讲不通。A.dropB.shortC.cutD.lack解析：解析 上文提到“检查每一项作业”肯定是对孩子反复尝试不认可，a lack of sth.“缺少某物”符合上下文语义。a drop of“一滴”和a cut of“一块”均句意不通；short为形容词，前面不加a。A.acquireB.earnC.gatherD.reach

32、解析：解析 四个选项中，只有earn“(通过努力)赢得；获得”能跟宾语grades“分数”搭配。acquire“习得”；gather“收集”；reach“达到”。A.exercisesB.defectsC.mistakesD.tests解析：解析 前半句建议父母检查孩子的作业(work)，后半句应该是让孩子rethink“反思”其中的“错误(mistakes)”，而不是所有的练习(exercise)；defect“缺点”和test“测试”与“作业”无关。A.perfectB.betterC.unusualD.complete解析：解析 but前后的句子表明：专家建议家长要检查作业，但不要走极端

33、：不要让孩子觉得作业必须_，此处应该选褒义程度最高的perfect。A.forgetB.refuseC.missD.ignore解析：解析 最后一段话锋一转：“这并不是说父母应该_作业”。显然前文(不要让孩子觉得作业必须完美无误)可能造成的误解是“忽略”(ignore)作业。A.haveB.prepareC.makeD.perform解析：解析 have homework为习惯表达，表示“有作业”；此处how much homework their kids have意为“老师给他们的孩子布置了多少作业”。A.classesB.groupsC.gradesD.terms解析：解析 空格后的46

34、是与前面early elementary years平行的，所以选grades“年级”，即46年级。A.aboutB.noC.muchD.few解析：解析 根据后文“高中2小时”，推断此处初中应该不超过1个半小时，所以选no，而非much；about和few不用于比较级之前。A.previouslyB.rarelyC.merelyD.consistently解析：解析 根据后文的talk to the teacher(跟老师谈谈)，既然需要跟老师谈谈，说明作业量很多，consistently“一贯地”能突出“量大”。previously“以前”；rarely“难得”；merely“仅仅”。A.

35、withB.inC.outD.up解析：解析 check with sb.意为“跟某人核实”；check in“(在旅馆、机场等)登记”；check out“结账离去”；check up (on) sth.“检查某事”。A.finishingB.loweringC.reducingD.declining解析：解析 因为作业太多，所以应该要求“减少(reduce)”。finish“完成”和lower“降下”不与homework搭配；decline表示“下降”时为不及物动词，后不能带宾语。As a physician who travels quite a lot, I spend a lot o

36、f time on planes listening for that dreaded Is there a doctor on board? announcement. Ive been 21 only oncefor a woman who had merely fainted.

41、rt attacks.（分数：40.00）A.calledB.addressedC.informedD.surveyed解析：解析 空格后提到“因为一位女士昏倒了”，作为一个physician(医生)，作者自然是被广播叫到(called)，故选A。inform“通知”；address“解决”；survey“调查”。A.accidentB.conditionC.incidentD.disaster解析：解析 本题用“the+选项”指代前一句的情形，“女士晕倒”用。incident“小事件”描述较准确，故选C。condition“条件”；disaster“灾难”；accident“事故”。A.so

42、onB.longC.manyD.often解析：解析 从第二段首句看出作者关心的是这种事件发生的频率，how often表示频率，故选D。A.confrontedB.treatedC.identifiedD.provided解析：解析 此处意为“如果_真实的空中医疗紧急情况，我会怎么做”，预测空格处填入“遇到”含义的词，confronted with意为“遇到”，符合上下文语义。identify with“认为与相等”；treat with“以招待”；provide with“提供”。A.forB.toC.byD.through解析：解析 access和to构成固定搭配，意为“可以得到”。A.

43、beforeB.sinceC.whenD.while解析：解析 根据上下文，这里应是“当时候”的意思，而下一小题的四个选项都是表示短暂性动作的动词，故只能用when，因为while表示“当时”只能接延续性动词，常用过去进行时，故选C。A.collectedB.conductedC.discoveredD.published解析：解析 本句的主语是杂志，所以与之搭配的谓语肯定是publish“出版，发表”。collect“收集”；discover“发现”；conduct“开展”。A.byB.ofC.withD.in解析：解析 这里是固定搭配，with interest“饶有兴趣”。A.amoun

44、tB.averageC.sumD.number解析：解析 这里表示的是“每天平均有30起事故”。A.significantB.heavyC.commonD.serious解析：解析 根据下一句“晕倒和眩晕是最常见的身体不适症状”，推断大多数情况并不严重(serious)。A.ForB.OnC.ButD.So解析：解析 上文说“晕倒和眩晕是最常见的身体不适症状”，说明不是太严重，而下文的serious enough to(严重到)提示上下文之间存在语义上的转折，故选C。A.requireB.inspireC.engageD.command解析：解析 这里require构成固定搭配require

45、sb. to do sth.“要求某人做某事”，本句意为“要求飞行员改变航线”。engage“使忙于”；inspire“鼓舞”；command“命令”。A.includeB.confineC.implyD.contain解析：解析 此处的句意为“最常见的严重情况_心脏病、中风及呼吸困难”，因此空格处应填入“包括”含义的词，include“包括”强调“包括者只是整体的一部分”，符合句意。contain“包含”强调的是“包含者仅仅是构成的某种成分”，如“月饼包含水分”。confine“限制”；imply“暗示”。A.enjoyableB.stimulatingC.tediousD.stressful解析：解析 本句为本段的主题句，看下文得知全
