16.airair解析：由前面的smog可知，此空处应填与smog相应的物质，又由后面的“hoversovercities”可知，此物质只能是“脏空气”。

17.farfar解析：能修饰too的副词只有far或much。

18.surveysurvey解析：根据后面的数据，空缺处指的是1993年的一项调查问卷，所以此处应填“survey”。

19.unlikeunlike解析：根据下文，以日本学生与美国和韩国的作对比，日本的学生不像韩国和美国的学生一样。所以此处应填“unlike”。

20.sellingselling解析：关键是看and后面的buying。本句话的意思是“商家分析市场的供需情况。”故答案为selling。

21.FortunatelyFortunately解析：由本句句意“…可以看到有解决办法的希望了。”可知，此空应填“幸运的是”。

22.readyready解析：顾客来到结算处，说明他们准备好了要付账。bereadyto的意思是“准备好了做某事”。故答案为ready。

23.ratherrather解析：此空所在句意为“用四个手指握笔而不是三个。”ratherthan表示“而不是”。

24.asas解析：such…as意为“这样的…如”。此空后为并列的三个分词短语，即“如”后跟的例举事项。

25.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”。

26.A解析：由A中的最后一句话“…withafictionalTVwitchbeingplayedbyanhonest—to—Godreallifewitch．”可知。

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。”因此正确答案为D。

28.C解析：由全文可以推断，要指出犯罪率下降的确切原因是很困难的。

29.A解析：“Comparisonofthesignificanceoftwoeconomicbooks”含有对两本经济书的对比信息的，我们可以看出四个书评中只有A中提到了两本书之间的关系。所以本题应选A。

30.B解析：由短文第一段最后一句“Exoticplastics，glassandceramicswillshapethefuturejustassurelyashavegeneticengineeringandcomputerscience．”可知，本文提到了三种新材料。

31.D解析：由D中的第三段“Inthesecondpart，thediscussionisextendedtoincludethepossibilitiesofprev
