31.purpose 【解析】从文中的第一句话“The most obvious purpose...”可以看出后面还有别的目的，而不是仅仅有最明显的目的。故答案为purpose。
32.first 【解析】根据题意，作者想在这里做一个比较，而比较的对象是目的。这里作者仅仅给出了两个目的，所以这里是和第一个目的进行比较。故答案为first。
33.production【解析】从前一句话“The manufacturers go beyond only telling consumers about their products.”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。
34.for 【解析】解析见上题。desire后面用介词for。故答案为for，表示“…的欲望”。
35.bought 【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。
36.though 【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。
37.do【解析】解析见上题，为了避免与前面的know重复，这里可以换做do。故答案为do。
38.selling 【解析】关键是看and后面的buying。本句话的意思是“商家分析市场的供需情况。”故答案为selling。
39.some 【解析】关键是注意and前后一致。“some rational and...emotional”，前面说促使顾客购买的动机有很多，有的是理性的，有的却是冲动。所以这里应该是some。故答案为some。
40.knowledge【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。
41.are 【解析】分析句子结构，这里缺少系动词be来构成动词的被动形式。故答案为ale。
42.reasons 【解析】本段的第一句话提出问题，问为什么在结算处摆设了那么多的商品。很明显，后面的文章对这个问题进行回答，并列举了原因。故答案为reasons。
43.ready 【解析】顾客来到结算处，说明他们准备好了要付账。be ready to的意思是“准备好了做某事”。故答案为ready。
44.on 【解析】“…的决定”英语表达为“decision on sth.”这里介词需要用on。故答案为on。
45.customer 【解析】从这个句子的宾语“…that he or she has done a good job of choosing the items.”可以看出，这里说的是顾客的行为，他们认为自己买这些商品是很理性的。故答案为customer。
46.display 【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。
