单选题 Water Resource Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the worlds population is expected to double in the next 50 years, many experts think We are on the edge of a widespread water crisis. But that doesn't have to be the outcome. Water shortages do not have to trouble the world—if we start valuing water more than we have in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation (灌溉) water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy.

单选题They Say Ireland"s the Best Ireland is the best place in the world to live for 2005, according to a life quality ranking that appeared in Britain"s Economist magazine last week. The ambitious attempt to compare happiness levels around the world is based on the principle that wealth is not the only measure of human satisfaction and well-being. The index of 111 countries uses data on incomes, health, unemployment, climate, political stability, job security, gender equality as well as what the magazine calls "freedom, family and community life". Despite the bad weather, troubled health service, traffic congestion (拥护), gender inequality, and the high cost of living, Ireland scored an impressive 8.33 points out of 10. That put it well ahead of second-place Switzerland, which managed 8.07. Zimbabwe, troubled by political insecurity and hunger, is rated the gloomiest (最差的), picking up only 3.89 points. "Although rising incomes and increased individual choices are highly valued," the report said, "some of the factors associated with modernization such as the breakdown (崩溃) in traditional institutions and family values in part take away from a positive impact." "Ireland wins because it successfully combines the most desirable elements of the new with the preservation of certain warm elements of the old, such as stable family and community life." The magazine admitted measuring quality of life is not a straightforward thing to do, and that its findings would have their critics. No. 2 on the list is Switzerland. The other nations in the top 10 are Norway, Luxembourg, Sweden, Australia, Iceland, Italy, Denmark and Spain. The UK is positioned at No. 29, a much lower position chiefly because of the social and family breakdown recorded in official statistics. The US, which has the second highest per capita GDP (人均国内生产总值) after Luxembourg, took the 13th place in the survey. China was in the lower half of the league at 60th.

单选题Spoilt for Choice Choice, we are made to believe, is a right. In daily life, people have come to expect endless situations about which they are required to make decisions one way or another. In the main, these are just annoying moments at work which demand some extra energy or brainpower, or during lunch breaks like choosing which type of coffee to order or indeed which coffee shop to go to. But sometimes selecting one option as opposed to another can have serious or lifelong consequences. More complex decision making is then either avoided, postponed, or put into the hands of the army of professionals, lifestyle coaches, lawyers, advisors, and the like, waiting to lighten the emotional burden for a fee. But for a good many people in the world, in rich and poor countries, choice is a luxury, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, created by companies and advertisers wanting to sell their wares. The main impact of endless choice in people's lives is anxiety. Buying something as basic as a coffee pot is not exactly simple. Easy access to a wide range of consumer goods induces a sense of powerlessness, even paralysis(瘫痪),in many people, ending in the shopper giving up and walking away, or just buying an unsuitable item that is not really wanted in order to solve the problem and reduce the unease. Recent surveys in the United Kingdom have shown that a sizeable proportion of electrical goods bought per household are not really needed. The advertisers and the manufacturers are, nonetheless, satisfied. It is not just their availability that is the problem, but the speed with which new versions of products come on the market. Advances in design and production mean that new items are almost ready by the time that goods hit the shelves. Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The classic example is computers, which are almost out dated once they are bought. At first, there were only one or two available from a limited number of manufacturers, but now there are many companies all with not only their own products but different versions of the same machine. This makes selection a problem. Gone are the days when one could just walk with ease into a shop and buy one thing; no choice, no anxiety. The plethora(过剩)of choice is not limited to consumer items. With the greater mobility of people around the world, people have more choice about where they want to live and work—a fairly recent phenomenon. In the past. nations migrated across the earth in search of food, adventure, and more hospitable environments. Whole nations crossed continents and changed the face of history. So the mobility of people is nothing new. The creation of nation states and borders effectively slowed this process down.
