27、B解析 动词辨义题。空格所在的句子缺少谓语动词，根据空格前的 has 可以判断，此处需要填入一个动词的过去分词形式。备选词汇中，increased“增加”和 raised“筹措；提高”均不能接 software作其宾语，故排除。developed 意为“研发”，developed an enterprise software 意为“研发一种企业软件”，符合此处语境，故选 B。解析：I解析 名词辨义题。根据空格前的 the day-to-day 和空格后的 of service workers 可以判断，此处需要填入一个名词。day-to-day 为形容词，意为“日常的”，相当于 daily。备

28、选词汇中能够被day-to-day 修饰的只有 performance“表现，行为”，故选 I。解析：M解析 动词辨义题。根据空格前的 can use.to 和空格后的 a patient“s medical history 可以判断，此处需要填入一个动词原形，构成 use sth. to do sth.这一结构。备选词汇中 leap“跳跃”显然不符合此处语境。skim 意为“浏览”，用在此处语义通顺，skim a patient“s medical history 意为“浏览病人的病历”。故选 M。解析：J解析 副词辨义题。根据空格前的 diagnose symptoms more 可以判断

29、，此处需要填入一个副词，修饰动词 diagnose。前文中提到，专业医护人员能够使用谷歌眼镜来浏览病人的病历，而无须参考电脑上的传统图表，由此可以推断，专业医护人员的看病速度可能加快，但是看病的准确度与看病历的途径没有必然的关联，因而排除 accurately“准确地”。eventually 意为“最终”，不能用于比较级，也可排除。quickly“快速地”符合此处语境，故选 J。解析：L解析 动词辨义题。根据空格前的 without ever 和空格后的 for abuilding map 可以判断，此处需要填入一个动名词，且其后能够接介词 for。备选词汇中只有 reaching“伸手取(某

30、物)”符合语境，故选 L。解析：E解析 形容词辨义题。根据空格前的 a 和空格后的.manager 可以判断，此处需要填入一个形容词对 Google product manager 加以修饰限定。备选词汇中只有 former“以前的”符合此处语境。故选E。解析：K解析 动词辨义题。空格所在的句子缺少谓语动词，再由空格前的 has 可以判断，此处需要填入一个动词的过去分词形式。备选词汇中能够接 over $1 million 这一具体数字作宾语的只有 increased和 raised。increased 意为“增加”，用在此处语义不通，故排除。raised 有“筹措；提高”之意，raised

31、over $1 million 意为“筹集了 100 多万美元”，语义通顺，故选 K。解析：D解析 名词辨义题。根据空格前的形容词 new 可以判断，此处需要填入一个名词。由破折号后面的 say 推知，破折号后面的内容对前面的 new.起到举例说明的作用，automatic sign-off after a few hours 意为“在几小时后自动登出系统”，显然不是一种 substance“物质”，而更应该是一种“特征”，因而 features“特点，特征”符合此处语境，故选 D。解析：C解析 副词辨义题。空格所在的句子并不缺少任何句子成分，再由空格前的 will 和空格后的have 可以判

32、断，此处需要填入一个副词。备选词汇中 eventually“最终”显然最符合此处语境，与句中的 in the future 相照应。故选 C。解析：O解析 形容词辨义题。空格所在的句子结构完整，再由空格前的 some 和空格后的 amount 可以判断，此处需要填入一个形容词修饰 amount“数量”。numerous 意为“很多的”，不能被 some 所修饰，可排除。variable 意为“变化不定的”，It may take some variable amount of time 意为“可能说不准这会花多长时间”，语义通顺。故选 O。Hourly Workers Earning Less

39、ization。该从句中缺少谓语动词，而整个句子的时态是一般现在时，由此可以判断，此处需要填入一个动词的第三人称单数形式，且须能和介词 for 一起搭配使用。备选词汇中只有 advocates“拥护；支持”符合此处语境。故选 A。解析：J解析 名词辨义题。根据空格前的 the 可以判断，此处需要填入一个名词。前文一直围绕各阶层的工作者在经济大萧条前后的收入落差展开，由此不难推知此处填入 recession“衰退，不景气”最符合语境。而且从语义来看，经济复苏之前挣得比经济复苏之后挣得多也违背常理，故而排除 recovery“复原，复苏”。concession“承认；让步”和 inequality

40、“不平等”也显然不符合此处语境。故选 J。解析：N解析 动词辨义题。空格所在的分句缺少谓语，而整个段落采用的是一股过去时，由此可以判断此处需要填入一个动词的过去式形式。从语义来看，前文讲到了中低收入群体在经济大萧条前后的收入对比，差距很大，而根据此处空格前的 only 和空格后的 a 0.6%drop 不难推知，该句要表达的是那些收入更高的人的工资则只下降了 0.6%。suffered“经历，遭受”符合此处语境，erased“抹去；消除”放入原文语义不通，故选 N。解析：K解析 名词辨义题。空格所在的分句为间接引用的报告中的一句话，该句中缺少主语，由此可以判断此处需要填入一个名词，且能够被空格

41、前面的 slow economic 所修饰。备选词汇中只有recovery“复原，复苏”符合此处语境。economic recovery 意为“经济复苏”。故选 K。解析：F解析 名词辨义题。根据空格前的形容词 widening 可以判断此处需要填入一个名词，备选词汇中，concession 意为“承认；让步”，不符合语境。inequality 意为“不平等”，强调高收入者和其他人群间的收入差距进一步扩大，符合此处语境，故选 F。解析：H解析 动词辨义题。空格前的 helped 后不能直接接 the divide 作宾语，由此可以判断此处需要填入一个动词原形。备选词汇中只有 narrow“(使

42、)变窄”符合此处语境，故选 H。需要注意 divide 在该句中用作名词，意为“差异，差别”。解析：D解析 动词辨义题。空格位于整个句子的主体部分，该部分缺少谓语动词，而该句采用的是一般过去时，由此可以判断此处需要填入一个动词的过去式。备选词汇中只有 erased“抹去；消除”符合此处语境，故选 D。解析：M解析 形容词辨义题。空格所在的句子结构完整，再由空格前的 less than 和空格后的 workers可以判断，此处需要填入一个形容词修饰 workers。该句旨在对人们在 2013 年的收入和 1979 年的收入进行对比，因而该对比应该是在类似或者相同岗位的人之间进行的，不然也就失去了

43、对比的意义和价值。备选词汇中 similar“类似的”符合此处语境，故选 M。Is There Water Beneath the Lunar Surface?You can“t squeeze blood from a turnip (萝卜), and 21 you can“t squeeze water from moon rocks, either.
