单选题 On the ground floor of the Federal Reserve building in Washington, DC, there is an electronic game which tests a visitor's skill at setting interest rates. You have to decide how to respond to events such as rising inflation or a stockmarket crash. If you get all the answers right, the machine declares you the next Fed chairman. In real life, because of huge uncertainties about data and how the economy works, there is no obviously right answer to the question of when to change interest rates. Nor is there any easy test of who will make the best Fed chairman. So who would The Economist select for the job? Alan Greenspan will retire as Fed chairman on January 31st, after a mere 181/2 years in the job. So George Bush needs to nominate a successor soon. Mr. Bush has a penchant for picking his pals to fill top jobs: last week he nominated his personal lawyer Harriet Miers to the Supreme Court. But his personal bank manager really would not {{U}}cut the mustard{{/U}} as Fed chairman. This is the most important economic-policy job in America—indeed in the whole world. The Fed chairman sets interest rates with the aim of controlling inflation, which in turn helps determine the value of the dollar, the world's main reserve currency. It is hardly surprising that financial markets worldwide can rise or fall on his every word. Financial markets are typically more volatile during the first year after the handover to a new chairman than during the rest of his tenure. In October 1987,barely two months after Mr. Greenspan took office, the stock market crashed. Current conditions for a handover are hardly ideal. America's economy has never looked so unbalanced, with a negative household savings rate, {{U}}a housing bubble{{/U}}, a hefty budget deficit, a record current-account deficit and rising inflation. Figures due on October 14th are expected to show that the 12-monthrate of inflation has risen above 4% —its highest since 1991.

单选题She was French; he was English; they had just moved to London from Paris. When he found out about her affair, she begged for a reconciliation. He was more ruthless: the same afternoon, he filed for divorce in France, one of the stingiest jurisdictions in Europe for the non-earning spouse and where adultery affects the court's ruling. Had she filed first in England her conduct would have been irrelevant, and she would have had a good chance of a large share of the marital assets, and even maintenance for life. International divorce is full of such dramas and anomalies, so the natural response of policymakers is to try to make things simpler and more predictable. But the biggest attempt in recent years to do just that, in a European agreement called Rome Ⅲ, has just been shelved. Instead, several EU countries are now pressing ahead with their own harmonisation deal. Many wonder if it will work any better. At issue is the vexed question of which country's law applies to the break-up of a mixed marriage. The spouses may live long-term in a third country and be temporarily working in a fourth. The worst way to sort that out is with expensive legal battles in multiple jurisdictions. The main principle at present is that the first court to be approached hears the case. Introduced in 2001, this practice has worked well in preventing international legal battles, but has made couples much more trigger-happy, because the spouse who hesitates in order to save a troubled marriage may lose a huge amount of money. Rome III aimed to remove the incentive to go to court quickly. Instead, courts in any EU country would automatically apply the local law that had chiefly governed the marriage. This approach is already in force in countries such as the Netherlands. A couple that moved there and sought divorce having spent most of the marriage in France, say, would find a Dutch court dividing assets and handling child custody according to French law. That works fine among continental European countries where legal systems, based on Roman law, leave little role for precedent or the judge's discretion. You can look up the rules on a website and apply them. But it is anathema in places such as England, where the system favours a thorough (and often expensive) investigation of the details of each case, and then lets judges decide according to previous cases and English law. Another snag is that what may suit middle-class expatriates in Brussels (who just happened to be the people drafting Rome Ⅲ) may not suit, for example, a mixed marriage that has mainly been based in a country, perhaps not even an EU member, with" a sharply different divorce law. Swedish politicians don't like the idea that their courts would be asked to enforce marriage laws based on, say, Islamic sharia. The threat of vetoes from Sweden and like-minded countries has blocked Rome Ⅲ. But a group of nine countries, led by Spain and France, is going ahead. They are resorting to a provision in EU rules-never before invoked-called " enhanced co-operation" This sets a precedent for a "multi-speed'" Europe in which like-minded countries are allowed to move towards greater integration, rather than seeking a "big-bang" binding treaty that scoops up the willing and unwilling alike. Some countries worry that using enhanced co-operation will create unmanageable layers of complexity, with EU law replaced by multiple adhoc agreements. The real lesson may be that Rome III was just too ambitious. A more modest but useful goal would be simply to clarify the factors that determine which court hears a divorce, and then let that court apply its own law. David Hodson, a British expert, proposes an international deal that would start by giving greatest weight to any prenuptial agreement, followed by long-term residency, and then take into account other factors such as nationality. That would then make it easier to end marriages amicably, with mediation and out-of-court agreement, rather than a race to start the beastly business of litigation.

单选题All animals must rest, but do they really sleep as we know it? The answer to this question seems obvious. If an animal regularly stops its activities and stays quiet and unmoving—if it looks as though it is sleeping—then why not simply assume that it is in fact sleeping? But how can observers be sure that an animal is sleeping? They can watch the animal and notice whether its eyes are open or closed, whether it is active or lying quietly, and whether it responds to light or sound. These factors are important clues, but they often are not enough. Horses and cows, for example, rarely close their eyes, and fish and snakes cannot close them. Yet this does not necessarily mean that they do not sleep. Have you ever seen a cat dozing with an eye partly open? Even humans have occasionally been observed to sleep with one or both eyes partially open. Animals do not necessarily lie down to sleep either. Elephants, for example, often sleep standing up, with their tusks resting in the fork of a tree. Finally, while "sleeping" animals often seem unaware of changes in the sounds and light and other stimuli around them, that does not really prove they are sleeping either. Observations of animal behavior alone cannot fully answer the question of whether or not animals sleep. The answers come from doing experiments in "sleep laboratories" using a machine called the electroencephalograph (EEC). The machine is connected to animals and measures their brain signals, breathing, heartbeat, and muscle activity. The measurements are different when the animals appear to be sleeping than when they appear to be awake. Using the EEC, scientists have confirmed that all birds and mammals studied in laboratories do sleep. There is some evidence that reptiles, such as snakes and turtles, do not truly sleep, although they do have periods of rest each day, in which they are quiet and unmoving. They also have discovered that some animals, like chimpanzees, cats, and moles (who live underground), are good sleepers while others, like sheep, goats, and donkeys, are poor sleepers. Interestingly, the good sleepers are nearly all hunters with resting places that are safe from their enemies. Nearly all the poor sleepers are animals hunted by other animals: they must always be watching for enemies, even when they are resting.

单选题{{B}}Text 1{{/B}} A weather map is an important tool for geographers. A succession of three of four maps presents a continuous picture of weather changes. Weather forecasts are able to determine the speed of air masses and fronts; to determine whether an individual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a synoptic picture of conditions in the atmosphere at a given time. All students of geography should be able to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States weather Bureau issues information about approaching storms, floods, frosts, droughts, and all climatic conditions in general. Twice a month it issues a 30-day "outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an analysis of the upper air levels with often set the stage for the development of air masses, fronts, and storms. Considerable effort is being exerted today to achieve more accurate weather predictions. With the use of electronic instruments and earth satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations. Extensive experiments are also in progress for weather modification studies. But the limitations of weather modification have prevented meteorological results except in the seeding of super-cooled, upslope mountainous winds which have produced additional orographical precipitation on the windward side of mountain ranges. Nevertheless, they have provided a clearer understanding of the fundamentals of weather elements.
