下图是“我国西部沿东经87°30′的地形剖面图”，下列说法正确的是

①该剖面经过青藏高原与西北内陆地区 

②图中④⑤均为干旱区，属于热带荒漠带 

③沿途见到的自然带具有从赤道到两极和从沿海向内陆两种分异规律 

④沿途可见到的自然带，既有从赤道到两极的地域分异，又有山地垂直地域分异

A．②④

B．②③

C．③④

D．①④

答案

答案：D

从图中看出，该剖面南起雅鲁藏布江谷地，沿东经87°30′一直到达我国新疆最北端的阿尔泰山，穿越了青藏高原和西北内陆地区。由于该剖面是沿经线所作，所以沿剖面在水平方向上应该看到自然带的分布符合从赤道到两极的地域分异；西部地区高山众多，从山麓到山顶可看到垂直地域分异。

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.
