15.A

16.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”。

17.rationalrational解析：从文章的后面可以知道，顾客们已经要结算了，认为都买了该买的商品。但是售货员在他们等着付账的过程中巧妙的利用顾客们的购物冲动向他们推销，而不是理性购物。故答案为rational。

18.byby解析：由日本政府收集的数据。考查被动语态的用法，“由…”用介词“by”。所以此处应填“by”。

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.reusereuse解析：由后一句“今天几乎每件东西都可以被扔掉。”可知，“…任何东西不再明智了。”中的空处应为“再利用”，这样前后两句逻辑上才能合理。

21.accordingaccording解析：accordingto为“依据”，为固定短语，意为“根据美国的民意调查”。所以此处填according。

22.whichwhich解析：由此句句子成分分析，此空以后的应为定语从句，修饰characteristics，所以此空应填which，引导定语从句。

23.werewere解析：考查被动语态的用法，注意分析句子成分。所以此
