16.creativitycreativity解析：本文是在讲述报酬、表扬与创造性的关系，此句意为“但是小心地使用小量的金钱报酬能激起分级学校孩子们的…”显然，空处应填“创造性”。

17.whatwhat解析：显然，此空后的句子应为"obscure”的宾语从句，而“isbeingwritten”中缺主语，可做主句的宾语、从句的主语的只有what。

18.offoff解析：turnoff是“关掉”的意思，此题考查动词短语的用法，根据上下文语境，这里意思是“关掉你的手机”。所以用副词“off”。

19.beingbeing解析：avoiddoingsth．意为“避免…”，avoid后必须跟名词或动名词。beovercritical意为“过分挑剔的”。

20.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。

21.ageage解析：此段话均是在比较不同年龄段的
