16.especiallyespecially解析：“Around1980manyJapanese，——youngpeople…”，“1980年左右许多日本人，尤其是年轻人…”，所以此处应填“especially”。

17.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。

18.youngyoung解析：本文均是在讲年轻的脑力工作者，故此空所应填的用于修饰“collegegraduates”的词也应是“年轻的”。

19.butbut解析：这里表达的前后句意是一种转折关系。前面说“hemayhavedreams，”而后面“hedoesnotallowthemtoblockhisknowledge…”的意思却是“但是他也不会让这些梦想阻挡自己对什么是现实的理解。”故答案为but。

20.outout解析：handout意为“分发，施舍”，为固定短语。

21.paperpaper解析：由前一句“…arenowpaperthrowaways．”可知，“不久以后我们将穿由纸制作的衣服。”

22.farfar解析：可用于修饰“toolittle”的只能是far，意为“太少，特别少”。

23.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”。

24.whatwhat解析：此题考查what引导的宾语从句。要注意分析句子中的成分，此空为listento后的宾语。所以此处应填引导词“what”。

25.workwork解析：根据上文，对比的是对工作的态度，所以此处应填“work”。

26.C解析：由短文倒数第二段可知美国只有四个州没有importtaxes。美国一共50个州，所以应该有46个有importtaxes。

27.AA解析：下面一段讲的是其他方法来鉴别毒藤，所以看过选项之后，我们可以推断出该空缺的是一些鉴别毒藤的方法，urushiol存在于毒藤
