In the following passage, there are 25 blanks representing words that are missing from the context. You are to put back in each of the blanks the missing word. Write your answers on the ANSWER SHEET. The time for this section is 25 minutes.
Some consumer researchers distinguish (1) "rational" motives and "emotional" (or "non-rational") motives. They use the term "rationality" (2) the traditional economic sense that assumes (3) consumers behave rationally when they carefully consider all alternatives (4) choose those that give them the greatest utility (i.e., satisfaction). (5) a marketing context, the term "rationality" implies that the consumer selects goods based (6) totally objective criteria, such (7) size, weight, price, and so on. "Emotional" motives imply the selection of goods (8) to personal or subjective criteria—the desire (9) individuality, pride, fear, affection or status.
The assumption underlying this distinction is (10) subjective or emotional criteria do not maximize utility or satisfaction. (11) , it is reasonable to assume that consumers always attempt to select alternatives that, (12) their view, serve to maximize satisfaction. Obviously, the assessment of satisfaction is a very personal process, based (13) the individual’s own needs as (14) as on past behavioral, social, and learning experiences. What may appear (15) irrational to an outside observer may be perfectly rational (16) the context of the consumer’s own psychological field. For example, a product purchased to enhance one’s self-image (such as a fragrance) is a perfectly rational form of consumer behavior. (17) behavior did not appear rational to the person who undertakes it (18) the time that it is undertaken, obviously he or she would not do it. (19) the distinction between rational and emotional motives does not appear to be warranted.
Some researchers go so far (20) to suggest that emphasis (21) "needs" obscures the rational, or conscious, nature of most consumer motivation. They claim that consumers act consciously (22) maximize their gains and minimize their losses; that they act not (23) subconscious drives but from rational preferences, (24) what they perceive to be (25) their own best interests.

选出以下不正确的两项()()

A.第1回,贾雨村姓贾名化,雨村是他的别号。为进京求取功名,曾寄居在姑苏城的葫芦庙里。后来中了进士,任姑苏知府,不到一年却又因恃才侮上被参而遭革职,偶然间成了林黛玉的家庭教师。因这层关系,才得以复职候缺,补得金陵应天府一职。

B.第1回,元宵佳节之夜,甄士隐命家人霍启抱了英莲去看社火花灯。霍启要去方便,便将英莲放在门槛上坐着。回来时,人已不见了,找了半夜,到天亮也没找到。没办法,霍启又不敢回去见主人,就逃往他乡。

C.第2回,林黛玉念书时,凡书中有“敏”字,都念做“密”字;写字遇着“敏”字,又减一二笔。贾雨村并未如此教她,当时只觉得黛玉言语举止另是一样。直到冷子兴告诉他林如海的夫人是贾敏,他才知其中原因。

D.第3回,林黛玉进贾府里,先后见了贾母、王夫人、邢夫人、李纨;迎春、探春、惜春;王熙凤;由两个舅妈带着,分别见了大舅舅贾赦,二舅舅贾政。吃过晚饭后,才见到宝玉。
