16.onon解析：此题也考查介词的用法，在电话中交谈，一般用onthephone。所以此处应填介词“on”。

17.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。

18.areare解析：分析句子结构，这里缺少系动词be来构成动词的被动形式。故答案为are。

19.whichwhich解析：由37题解析可知此空应为一个引导定语从句的词，即which，其后的定语修饰“several(typesofcontamination)”。

20.accordingaccording解析：此句意为“…一项个性与社会心理学的六月杂志的研究。”显然，空处应填“根据”。

21.thatthat解析：参见32题解析，idea与bigachievementsrarelycomeeasilyandquickly是同位语，故此空应填that，引导同位语从句。
