阅读《我的信念》,回答问题。

  ①生活对于任何一个男女都非易事。我们必须有坚韧不拔的精神,最要紧的,还是我们自己要有信心。我们必须相信,我们对每一件事情都具有天赋的才能。并且,无论付出多大代价;都要把这件事完成。当事情结束的时候,你要能够问心无愧地说:“我已经尽我所能了。”

  ②有一年的春天,我因病被迫在家里休息数周。我注视着我的女儿们所养的蚕,蚕结着茧子,这使我很感兴趣。望着这些蚕固执地、勤奋地工作着,我感到我和它们非常相似。像它们一样,我总是耐心地集中在一个目标上,我之所以如此,或许是因为有某种力量在鞭策着我正如蚕被鞭策着去结它的茧子一般。

  ③近五十年来,我致力于科学的研究,而研究,基本上是对真理的探索。我有许多美好快乐的记忆。少女时期,我在巴黎大学孤独地度过求学的岁月。在那整个时期,我丈夫和我在简陋的环境里艰辛地研究,我们专心致志,像在梦幻之中一般。后来我们发现了镭。

  ④我一生中,总是追求安静的工作和简单的家庭生活。为了实现这个理想,我竭力保持宁静的环境,以免受人事和盛名的侵扰。

  ⑤我觉得,在科学方面,我们是有对事而不是对人的兴趣。当皮埃尔.居里和我决定应否在我们的发现上获取经济上的利益时,我们都认为这是违反我们的纯粹研究观念的。因而我们没有申请镭的专利,也就抛弃了一笔财富。我坚信我们是对的。诚然,人类需要寻求现实的人,他们在工作中获得很大的报酬。但是,人类也需要梦想家——科学研究强烈地吸引着他们,使他们忘我地工作,没有闲暇,也无热情去谋求物质上的利益。我惟一的奢望,是在一个自由国家中,以一个自由学者的身份从事研究工作。我从不认为这种权益是理所当然的,因为在二十四岁以前,我一直居住在被占领被蹂躏的波兰。我估量过法国自由的价值。

  ⑥我并非生来就是一个性情温和的人。我很早就知道,许多像我一样敏感的人,即使受了一言半语的呵责,也会过分懊恼,他们尽量隐藏自己的敏感。从我丈夫温和沉静的性格中,我获益匪浅。当他猝然长逝以后,我便学会了忍耐。年纪渐老,我愈会欣赏生活中的种种琐事,如栽花、植树、建筑,对诵诗和眺望星辰,也有一点兴趣。

  ⑦我一直沉醉于世界的优美之中,我所热爱的科学也不断展现它崭新的远景。我认定科学本身就具有伟大的美。一位从事研究工作的科学家,不只是一个技术人员,而且,他更像一个小孩儿,迷醉在如同神话故事一样的大自然中。科学的这种魅力,就是使我终生能够在实验室里埋头工作的主要因素了。

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.
