14.C

15.A

16.populationpopulation解析：由下一句“越来越多的人正在制造更多的、垃圾。”可知，此处应指“膨胀的人口”，即explodingpopulation。

17.ofof解析：beofthesame…意为“是一样…”，此句意为“…在正确的指导下，他们能继续学习，继续通过干许多一样复杂的工作而获得多样性。”

18.thosethose解析：文章中提到“16-19岁之间的日本青年跟25-29岁之间的青年对比”，这里缺少代词，替代“Japaneseyouth”。所以此处应填“those”

19.byby解析：此空所在短句意为“报酬经常毁掉创造性，…鼓励依赖他人的认可和礼物。”显然，空处应填“通过”，在英语中介词by即可表达此意。

20.amongamong解析：此句意为“后一种观点得到了许多支持者，尤其…教育家。”显然，空处应填“在…中”，介词among即有此意。

21.lookinglooking解析：与介词for的固定搭配，意为“寻求…”，这里指的是寻求新的价值观。所以此处应填“looking”。

22.dividedivide解析：根据上下文语境，这里是“分为”，divide…upinto意为“把…划分为”。所以此处应填动词“divide”。

23.somesome解析：这里需要填写的是商品的名称，就是说摆在出口结算处的那些小商品。泛指时用some。故答案为some。

24.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”。

25.therebythereby解析：本句句意为“我们也正在污染海洋，杀死了鱼类，…剥夺了我们那无价的食物供应。”显然，此空前后为因果关系，而且depriving前不能用so或其他表因果关系的连词，而只能用介词thereby。

26.A解析：文章第三段提到“TheAmericanideaofthenationalgoodhasneverbeenbasedonnationalcooperationbutratheronthefreedomoftheindividual,…．”这说明美国的国家利益不是建立在全民合作基础之上的，相反，这种基础是个人的自由。故应选A。

27.A解析：由文章第四段中的“Anotherfamousexampleistheelectrical．Thisfishgivesanevenmorepowerfulshock．”可知。

28.C解析：由短文第一段中的“Smithnoted，‘Betweentheamoutofsodiumapersonconsumesandheartdisease，circulatorydisorders，strokeandevenearlydeath．’”可知。

29.C解析：由C中的第二段“…asubstantialagriculturesector，whichcontributestodeforestation，theerosionofthetopsoilanddesegification．hasledtoextremepressuresontheenvironmentand…”可知。

30.D解析：这是一个通篇的中心归纳的考察题。文章一开始就指出“Beforeabigexam，asoundnight’ssleepwilldoyoubetterthanpongovertextbooks．”意思是在晚上好好的睡觉对记忆是有好处的。最后作者有归纳了研究的结果，“…concludedthatthenerveconnectionsinvolvedinmemoryarereinforcedthroughreactivationduringREMsleep…．”也说明结
