Environmental protection 答案 57.C 58.A 59.A 60.B Passage 7 Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions-those are the practical lesson being drawn from recent research by psychologist John A. Bargh. Psychologists have known that one person’s perception of another’s “warmth is a powerful determiner in social relationships. Judging someone to be either “warm or “cold is a primary consideration, even trumping evidence that a “cold person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother rather than one made of wire, even when the wire “mother carried a food bottle. Harlow’s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills. Feelings of “warmth and “coldness in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm or “cold is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries. To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses, handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink. “We are grounded in our physical experiences even when we think abstractly, says Bargh. 【查看更多】

    　　All to often, a choice that seems sustainable(可持续的)turns out on closer examination to be problematic．Probably the best example is the rush to produce ethanol(乙醇)for fuel from corn．Corn is a renewable resouree－you can harvest it and grow more, almost limitlessly．So replacing gas with corn ethanol seems like a great idea．

    　　One might get a bit more energy out of the ethand than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem．Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food．That result leads to turning the fallow land－including, in some cases, rain forest in places such as Brazil－into farmland, which in turn gives off lots carbon dioxide(CO2)into the air．Finally, over many years, the energy benefit from buring ethanol would make up for the forest loss．But by then, climate change would have progressed so far that it might not help．

    　　You cannot really declare any practice“sustainable”until you have done a complete life-cycle analysis of its environmental(环境的)costs．Even then, technology and public policy keep developing, and that development can lead to unforeseen and undesired results．The admirable goal of living sustainably requires plenty of thought on an ongoing basis．

    All too often , a choice that seems sustainable（可持续的）turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol（乙醇）for fuel from corn . Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea.

    One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem.
