单选题You wouldn't expect an Information Age company like Intel to get on the wrong side of environmentalists, but the company's recent 42 billion expansion at Rio Rancho, New Mexico, plunged the world's largest semiconductor maker into an age-old Western problem: water rights. Chip plants consume millions of gallons of water a day, mainly to wash microscopic dirt from the surface of chips. That's a problem in the dry West, where, as Twain remarked, whiskey is for drinking, water is for fighting about. During construction of the new 1.3 million-square-foot chip-making plant, which starts production this month, residents and activists complained that the company's expanding thirst would be too great a drain on local supplies. After weeks of public hearings, the state of New Mexico last year granted Intel 72% of the water it requested. The strife at Rio Rancho is the most intense the industry has faced. "I think it sensitized us, " says Howard High, spokesman for Intel. "We have a lot of efforts under way to try and minimize the amount of water we use. " Current conservation efforts may not work for an industry that in North America is expected to double in size to $ 75 billion in sales in the next three years. The trend is to reuse treated wastewater from chip cleaning in places such as cooling towers and air-conditioning systems. Motorola employs such methods in Phoenix and Austin. Recycling water for chip cleaning is the most logical approach. But the technology to make ultra-pure water for such a closed-loop system is still too costly. New technologies could eventually take the water out of chip cleaning. One company, Radiance Services, a six-person start-up based in Bethesda, Maryland, holds patents for a new "dry cleaning" method. Using laser light and inert gas (惰性气体) to lift impurities (杂质，不洁物) from surfaces of a chip, Radiance claims its process can clean as effectively as the current water-based methods.

单选题The world has never been more closely and intricately connected. Our behavior (51) the environment we all share, and we are tied into a global economy and global communication system. (52) choosing to buy one garment rather than another we help determine whether someone on the other side of the world retains or (53) their job; emissions from one part of the world contribute to a hole in the ozone layer somewhere else; we can (54) with others anywhere via satellites, the Internet and the mobile phone. This interdependency, (55) "connexity", is the defining characteristic of the world today. However, despite connexity, human beings have also (56) been, more separate. Belief in individual rights and freedoms is at the heart of the West's world view. People nowadays insist their freedom to (57) how to live, who to love, what to consume and what to believe. In economics, the sovereignty of the consumer and the shareholder is paramount. In politics, the sovereignty of nations remains a (58) concern. In this inspiring and important book Mulgan argues that our freedom and our connectedness are set or collision course and argues that the (59) way out of our current impasse (僵局) is to go beyond our sense of ourselves as (60) unit, and recognize the webs of mutual responsibility in which we live.

单选题People can be addicted to different things—e.g. alcohol, drugs, certain foods, or even television. People who have such addition are compulsive, i.e. they have a very powerful psychological need that they feel they must spend money. This compulsion, like most others, is irrational—impossible to explain reasonably. For compulsive spenders who buy on credit, charge accounts are even more exciting than money. In other words, compulsive spenders feel that with credit, they can do anything. Their pleasure in spending enormous amounts is actually greater than the pleasure that they get from the things they buy. There is special psychology of bargain hunting. To save money, of course, most people search for sales, low prices and discounts. Compulsive bargain hunters, however, often buy things they don"t need just only because they are cheap. They believe that they are helping their budgets, but they are really playing an exciting game: when they can buy something for less than other people, they feel that they are winners. Most people, experts claim, have two reasons for their behavior: a good reason for things that they do and the real one. Of course, it is not only scientists who understand the psychology of spending habits, but also business people. Stores, companies, and advertisers use psychology to increase business: they consider people"s needs for love, power, or influence, their basic value, their beliefs and opinions, and so on in their advertising and sales methods. Psychologists can often use a method called "behavior therapy" to help individuals solve their personality problems. In the same way, they can help people who feel that they have problems with money.
