16.toto解析：besubjectedto为固定搭配，“使遭受，使服从”的意思，要学会跨过其他成分寻找主干。所以此处应填介词“to”。

17.boughtbought解析：本句的前一句话说“顾客认为他们需要一些他们其实不需要的商品。”这就是广告的作用。但是买完之后，“他们却不知道当时为什么买了这种商品。”这里是被动的句式。故答案为bought。

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.suchsuch解析：“poorposture，leaningtoo…tothedesk，using…”均是对characteristics的举例说明，而举例用英语说应为“suchas”。

20.thethe解析：此处缺冠词，在年轻人之间，用the表示特指。所以此处应填“the”。

21.whatwhat解析：这句话的意思是“这就是商家和卖者希望顾客们做的事情”，what引导的是一个表语从句，故答案为what。

22.customercustomer解
