16.themthem解析：本题考查代词的用法，根据上下文，此处句意为“人们使用这些小玩意儿。”上文已经提到gadgets，所以这里用代词“them”代替。

17.likelylikely解析：前面所说的thepersonwhoisdown-to-earth与thepersonwhosebothfeetontheground大体是一类人，所以这里表达的意思是“很有可能就是一类人”。belikelytodo就表达了这种意思。故答案为likely。

18.butbut解析：此句意为“30岁的人表现出非常不同的握笔方式，…超过40岁的人都统一用三个手指握笔。”显然，此空处表转折。

19.thoughthough解析：本句话的意思是“尽管知道顾客们可能不知道自己为什么买了这些商品，但是卖家却知道怎么去做。”故答案为though。

20.ofof解析：“对现实的了解”的英文表达是“theunderstandingofreality”，这里的介词用of。故答案为of。

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.productionproduction解析：从前一句话“Themanufacturersgobeyondonlytellingconsumersabouttheirproducts．”可以看出，一方面广告要介绍自己的产品，而第二个目的就是卖掉自己的产品。所以这里作者想要表达的意思是“广告要使得顾客有一种购买的欲望去购买自己的产品。”故答案为production。

23.displaydisplay解析：这里要回应本段第一句话中的“displayed”。在出口结算处展示的这些小商品无疑是一种诱惑。这里需要用名词形式。故答案为display。

24.personperson解析：本句话的意思是“与此相反的一类人是那些想入非非的人。”根据上下文的要求这里应该填入man的同义词。故答案为person。

25.SometimeSometime解析：通过对后面句子的分析，我们可以知道那些想入非非、飘飘欲仙的人有朝一日也是可以“双脚落地的”，那就是“sharpwordsfromteacher”，所以这里表示的是“有朝一日”，故答案为sometime。

26.D解析：这是一个通篇的中心归纳的考察题。文章一开始就指出“Beforeabigexam,asoundnight’ssleepwilldoyoubetterthanporingovertextbooks.”意思是在晚上好好的睡觉对记忆是有好处的。最后作者有归纳了研究的结果，“…concludedthatthenerveconnectionsinvolvedinmemoryarereinforcedthroughreactivationduringREMsl

27.C解析：通过全文的理解，我们可以发现作者在列数了经济形势不好的局面之后，也表明了人们对此依然存在着乐观态度，有的人还能从中受益，所以作者的态度应该是“对此加以注意，但不要惶恐。”故应选C。

28.C解析：本文均是在讲述青少年的自杀问题。

29.A解析：从文章最后一句话
