16.worseworse解析：“the+比较级，the+比较级”，意为“越…越…，”根据上下文，本句句意为“身边的小玩意儿越多，事情似乎就会变得越糟糕。”所以此处应填“worse”。

17.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”。

18.knowledgeknowledge解析：前面讲商家正确的分析市场的供需信息，知道是什么因素影响顾客的购买欲望。这就是他们利用的信息知识。故答案为knowledge。

19.someonesomeone解析：由本文的第一句话“‘Down-to-earth’meanssomeoneorsomethingthatishonest，realisticandeasytodealwith.”可知“Down-to-earth”指的是诚实，现实、平易近人的那些人。这里的someone和后面是相对应的。故答案为someone。

20.betweenbetween解析：此句意为“Thomas先生尽管不能在握笔方式和拼写准确性之间建立重要的统计学联系，…”所以答案为介词between。

21.dumpingdumping解析：由本句句意“通过将污水和化学物质…入河流和湖泊，…”可知，此空处显然应为“倒”。又因为介词后只能用dumping，而不能用dump。

22.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。

23.towardtoward解析：作者要表达的意思是“我怎么才能对别人诚实。”英语中表达“对某人…”一般是用介词toward。故答案为toward。

24.dividedivide解析：根据上下文语境，这里是“分为”，divide…upinto意为“把…划分为”。所以此处应填动词“divide”。

25.thoughthough解析：参见47题解析，由本句句意“…更便宜，…它的95％的部件仍可以使用。”可知，此空处应填“尽管，即使”，即eventhough。

26.D解析：根据这篇文章，普遍认为大脑的区别由什么因素引起的?短文第三段倒数第二句话说“Wetendtothinkthat，istheinfluenceofsocietythatproducesthesedifferences．”即我们认为社会的影响造成了这些区别。A、B、c均不符合题意。所以本题应选D。

27.A解析：从文章最后一段“Potentialhomebuyerswouldcheerforlowerinterestrates.Employerswouldn'tmindalittlefewerbubblesinthe{obmarket…”可以
