李时珍(公元1518—1593年)是明代著名医药学家，湖北人，出生在一个医学世家。他从小就对医学产生了浓厚兴趣，24岁那年，开始给人看病。他诊断认真，待病人热情，深受人民爱戴。
在行医过程中，李时珍发现当时的医药书籍错误太多，有些分类不清，有些记载的药性不准，还有些加进了迷信的东西。医药书的好坏关系着人们的身体健康和生命，李时珍决心写一部比较科学完善的医药书。于是，从35岁开始，他集中全部精力编写《本草纲目》。
为了写好这部书，他读了800多种书籍，走访了长江、黄河流域的许多地方，虚心向当地人民请教，广泛收集药物标本和民间药方，还在家里试种药材。经过27年的艰苦努力，终于在1578年完成了《本草纲目》这部世界闻名的医药巨著。
《本草纲目》共190多万字，分16部，52卷，60类。收集的药物共1892种，每种药物的产地、形状、颜色、气味和主治病症都写得明白，有条理；收入的药方有11096个；为了帮助人们辨认药物，绘制了插图1110幅，形象地表明了各种药物形状。
《本草纲目》不但是一部总结中国2000年来药物知识的巨著，而且还是一部植物学巨著。1647年一位波兰人把《本草纲目》译成《中国植物志》，于1659年出版，对欧洲植物学有很大影响。此后，《本草纲目》先后被译成多种文字，流传到各国。
今天，在湖北蕲春有李时珍墓和药圃，供人们参观游览。

李时珍是：

A．古代著名诗人
B．现代著名医药学家
C．明代著名医药学家
D．当代著名医生

填空题

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.
