15.A

16.importantimportant解析：从本句后面的一句话可以看出，Adown-to-earthperson就算是重要的人物，他们也不会把这种显赫写在脸上。所以前面应填important。故答案为important。

17.proportionproportion解析：此处意为很大比例的学生仍然喜欢简单的工作，所以此处应填“proportion”。

18.whatwhat解析：解析同上。这里是一个名词性从句，what在句中做主语。故答案为what。

19.awareaware解析：beawareof，固定搭配，意为“意识到”。所以此处应填“aware”。

20.awareaware解析：beawareof，固定搭配，意为“意识到”。所以此处应填“aware”。

21.atat解析：此题考固定搭配，atone’sdisposal，意为“任某人自由支配、使唤”。所以此处应填介词“at”。

22.whosewhose解析：这是一个后置定语从句，用whose来引导，表示mind与dreamer的所属关系。故答案为whose。

23.WarmWarm解析：由此句中的“contrastiveviews”可知，观点是相对的，此空所在短句意为“从…赞扬到冷酷的批评”，显然，应是“热烈的”。

24.dumpingdumping解析：由本句句意“通过将污水和化学物质…入河流和湖泊，…”可知，此空处显然应为“倒”。又因为介词后只能用dumping，而不能用dump。

25.killingkilling解析：本句意为“通过无控制地使用杀虫剂，人类已经污染了土地，…野生动物。”显然，此空处应填“杀害”，但不能填kill，因为英语中无连词时不可能有两个谓语，故应填killing，killingthewildlife是现在分词做伴随状语。

26.CC解析：上一段中提到的“myth”是有关家庭关系的问题，担心家庭关系会因为老龄化问题而使亲人之间疏远。C中研究中心的伦理学家对这一问题进行了佐证。年长者对家庭需要贡献的角色越来越重要，所以这些担心都是没必要的，可以找到解决措施的。

27.D解析：第一段最后一句话指出了疫苗短缺所暴露出来的问题。“Thisreemphasizesthefragilityofourvaccinesupply．”saysDr．MartinMyersoftheNationalNetworkforImmunizationInformation，“andthelackofredundancyinoursystem．”“这再次凸显出我们疫苗供应的脆弱性，”全国免疫信息网的马丁·迈尔斯医生说，“此外，我们也没有必要的补救机制。”因此正

28.AA解析：上一段最后一句“…suchasdrainingblood…”与A中的“Themassivewartimeblooddrives…”对应。

29.C解析：由C中的第二段“ThispartrepresentsthetensionsbetweenAmericaandFrance．”可知。

30.FF解析：后面的一段说明了相反的情况。“Thepersonwearingtheglasses…”与选项中的“…twopeoplewearsdarkglasses”相对应，故应选F。

31.A解析：第六段中男主人看到清理垃圾的车，误以为是Mi
