单选题 Coming to An Office Near You The effect of today's technology on tomorrow's jobs will be immense—and no country is ready for it. [A] Innovation, the elixir (灵丹妙药) of progress, has always cost people their jobs. In the Industrial Revolution artisan (工匠) weavers were swept aside by the mechanical loom. Over the past 30 years the digital revolution has displaced many of the mid-skill jobs that supported 20th-century middle-class life. Typists, ticket agents, bank tellers and many production-line jobs have been dispensed with, just as the weavers were. [B] For those, including this newspaper, who believe that technological progress has made the world a better place, such churn (搅动) is a natural part of rising prosperity. Although innovation kills some jobs, it creates new and better ones, as a more productive society becomes richer and its wealthier inhabitants demand more goods and services. A hundred years ago one in three American workers was employed on a farm. Today less than 2% of them produce far more food. The millions freed from the land were not consigned to joblessness, but found better-paid work as the economy grew more sophisticated. Today the pool of secretaries has shrunk, but there are ever more computer programmers and web designers. Remember Ironbridge [C] Optimism remains the right starting-point, hut for workers the dislocating (扰乱) effects of technology may make themselves evident faster than its benefits. Even if new jobs and wonderful products emerge, in the short term income gaps will widen, causing huge social dislocation and perhaps even changing politics. Technology's impact will feel like a tornado (龙卷风), hitting the rich world first, but eventually sweeping through poorer countries too. No government is prepared for it. [D] Why be worried? It is partly just a matter of history repeating itself. In the early part of the Industrial Revolution the rewards of increasing productivity went disproportionately to capital; later on, labour reaped most of the benefits. The pattern today is similar. The prosperity unleashed by the digital revolution has gone overwhelmingly to the owners of capital and the highest-skilled workers. Over the past three decades, labour's share of output has shrunk globally from 64% to 59%. Meanwhile, the share of income going to the top 1% in America has risen from around 9% in the 1970s to 22% today. Unemployment is at alarming levels in much of the rich world, and not just for cyclical reasons. In 2000, 65% of working-age Americans were in work; since then the proportion has fallen, during good years as well as bad, to the current level of 59%. [E] Worse, it seems likely that this wave of technological disruption to the job market has only just started. From driverless cars to clever household gadgets, innovations that already exist could destroy lots of jobs that have hitherto (迄今) been untouched. The public sector is one obvious target: it has proved singularly resistant to tech-driven reinvention. But the step change in what computers can do will have a powerful effect on middle-class jobs in the private sector too. [F] Until now the jobs most vulnerable to machines were those that involved routine, repetitive tasks. But thanks to the rise in processing power and the ubiquity (无处不在) of digitised information ('big data'), computers are increasingly able to perform complicated tasks more cheaply and effectively than people. Clever industrial robots can quickly 'learn' a set of human actions. Services may be even more vulnerable. Computers can already detect intruders in a closed-circuit camera picture more reliably than a human can. By comparing reams of financial or biometric data, they can often diagnose fraud or illness more accurately than any number of accountants or doctors. One recent study by academics at Oxford University suggests that 47% of today's jobs could be automated in the next two decades. [G] At the same time, the digital revolution is transforming the process of innovation itself, as our special report explains. Thanks to off-the-shelf code from the Internet and platforms that host services (such as Amazon's cloud computing), provide distribution (Apple's app store) and offer marketing (Facebook), the number of digital start-ups has exploded. Just as computer-games designers invented a product that humanity never knew it needed but now cannot do without, so these firms will no doubt dream up new goods and services to employ millions. But for now they are singularly light on workers. When Instagram, a popular photo-sharing site, was sold to Facebook for about $1 billion in 2012, it had 30m customers and employed 13 people. Kodak, which filed for bankruptcy a few months earlier, employed 145,000 people in its heyday. [H] The problem is one of timing as much as anything. Google now employs 46,000 people. But it takes years for new industries to grow, whereas the disruption a startup causes to incumbents (现任者) is felt sooner. Airbnb may turn homeowners with spare rooms into entrepreneurs, but it poses a direct threat to the lower end of the hotel business—a massive employer. No time to be timid [I] If this analysis is halfway correct, the social effects will be huge. Many of the jobs most at risk are lower down the ladder (logistics, haulage), whereas the skills that are least vulnerable to automation (creativity, managerial expertise) tend to be higher up, so median wages are likely to remain stagnant for some time and income gaps are likely to widen. [J] Anger about rising inequality is bound to grow, but politicians will find it hard to address the problem. Shunning (避开) progress would be as useless now as the Luddites' protests against mechanised looms were in the 1810s, because any country that tried to stop would be left behind by competitors eager to embrace new technology. The freedom to raise taxes on the rich to punitive levels will be similarly constrained by the mobility of capital and highly skilled labour. [K] The main way in which governments can help their people through this dislocation is through education systems. One of the reasons for the improvement in workers' fortunes in the latter part of the Industrial Revolution was because schools were built to educate them—a dramatic change at the time. Now those schools themselves need to be changed, to foster the creativity that humans will need to set them apart from computers. There should be less rote-learning and more critical thinking. Technology itself will help, whether through MOOCs (massive open online courses) or even video games that simulate the skills needed for work. [L] The definition of 'a state education' may also change. Far more money should be spent on pre-schooling, since the cognitive abilities and social skills that children learn in their first few years define much of their future potential. And adults will need continuous education. State education may well involve a year of study to be taken later in life, perhaps in stages. [M] Yet however well people are taught, their abilities will remain unequal, and in a world which is increasingly polarized (两极化) economically, many will find their job prospects dimmed and wages squeezed. The best way of helping them is not, as many on the left seem to think, to push up minimum wages. Jacking up the floor too far would accelerate the shift from human workers to computers. Better to top up low wages with public money so that anyone who works has a reasonable income, through a bold expansion of the tax credits that countries such as America and Britain use. [N] Innovation has brought great benefits to humanity. Nobody in their right mind would want to return to the world of handloom weavers. But the benefits of technological progress are unevenly distributed, especially in the early stages of each new wave, and it is up to governments to spread them. In the 19th century it took the threat of revolution to bring about progressive reforms. Today's governments would do well to start making the changes needed before their people get angry.

单选题 It is not often realized that women held a high place in southern European societies in the 10th and 11th centuries. As a wife, the woman was protected by the setting up of a dowry (彩礼) or decimum. Admittedly, the purpose of this was to protect her against the risk of desertion, but in reality its function in the social and family life of the time was much more important. The decimum was the wife's right to receive a tenth of all her husband's property. The wife had the right to withhold consent, in all transactions the husband would make, and more than just a right: the documents show that she enjoyed a real power of decision equal to that of her husband. In no case did the documents indicate any degree of difference in the legal status of husband and wife. The wife shared in the management of her husband's personal property, but the opposite was not always true. Women seemed perfectly prepared to defend their own inheritance against husbands who tried to exceed their rights, and on occasion they showed a fine fighting spirit. A case in point is that of Maria Vivas, a Catalan woman of Barcelona. Having agreed with her husband Miro to sell a field she had inherited for the needs of the household, she insisted on compensation. None being offered, she succeeded in dragging her husband to the scribe (法学家) to have a contract duly drawn up assigning her a piece of land from Miro's personal inheritance. The unfortunate husband was obliged to agree, as the contract says, 'for the sake of peace.' Either through the dowry or through being hot-tempered, the Catalan wife knew how to win herself, with the context of the family, a powerful economic position.
