单选题 Technology can make us smarter or stupider, and we need to develop a set of principles to guide our everyday behavior and make sure that tech is improving and not hindering our mental processes. One of the big questions being debated today is: What kind of information do we need to have stored in our heads, and what kind can we leave 'in the cloud, ' to be accessed as necessary? An increasingly powerful group within education are championing 'digital literacy'. In their view, skills beat knowledge, developing 'digital literacy' is more important than learning mere content, and all facts are now Google-able and therefore unworthy of committing to memory. But even the most sophisticated digital literacy skills won't help students and workers navigate the world if they don't have a broad base of knowledge about how the world actually operates. If you focus on the delivery mechanism and not the content, you're doing kids a disservice. Indeed, evidence from cognitive science challenges the notion that skills can exist independent of factual knowledge. Data from the last thirty years leads to a conclusion that is not scientifically challengeable: thinking well requires knowing facts, and that's true not only because you need something to think about. The very processes that teachers care about most—critical thinking processes—are intimately intertwined (交织) with factual knowledge that is stored in long-term memory. In other words, just because you can Google the date of Black Tuesday doesn't mean you understand why the Great Depression happened or how it compares to our recent economic slump. There is no doubt that the students of today, and the workers of tomorrow, will need to innovate, collaborate and evaluate. But such skills can't be separated from the knowledge that gives rise to them. To innovate, you have to know what came before. To collaborate, you have to contribute knowledge to the joint venture. And to evaluate, you have to compare new information against knowledge you've already mastered. So here's a principle for thinking in a digital world, in two parts. First, acquire a base of factual knowledge in any domain in which you want to perform well. This base supplies the essential foundation for building skills, and it can't be outsourced (外包) to a search engine. Second, take advantage of computers' invariable memory, but also the brain's elaborative memory. Computers are great when you want to store information that shouldn't change. But brains are the superior choice when you want information to change, in interesting and useful ways: to connect up with other facts and ideas, to acquire successive layers of meaning, to steep for a while in your accumulated knowledge and experience and so produce a richer mental brew.

单选题The population of the world is growing at a dangerous________.

单选题Much of continental Europe is in poor shape. True, the aggregate wealth of people is little changed and the social capital in museums, parks and other amenities is still intact. Yet, in the western part, the economy is failing society. Inclusion of ethnic minorities and youth in the economy is more lacking than ever. Among those who do participate, fewer are prospering. It is a measure of the decline that, in almost every country, the growth of wage rates has steadily slowed since 1995. What has gone wrong? European economists speak of a loss of competitiveness in southern Europe. They suggest that output and employment are down, relative to the past trend, because wages leapt ahead of productivity, making labour too expensive and forcing employers to cut back. Taking this perspective, some German economists argue that wages need to fall in the affected economies. Others argue instead for monetary stimulus—for instance, asset purchases by central banks—to raise prices and make current wage rates affordable. Economists of a classical bent lay a large part of the decline of employment, and thus lagging output, to a contraction of labour supply. And they lay that contraction largely to outbreaks of fiscal profligacy—as happened in Europe from the mid-1990s to the mid-2000s. Disciples of Keynes, who focus on aggregate demand, view any increase in household wealth as raising employment because they say it adds to consumer demand. They say Europe needs a lot more fiscal "profligacy" if it is to bring unemployment down. Some evidence favours the classics. Yet both sides of this debate miss the critical force at work. The main cause of Europe"s deep fall—the losses of inclusion, job satisfaction and wage growth—is the devastating slowdown of productivity that began in the late 1990s and struck large swathes of the continent. It holds down the growth of wages rates and it depresses employment. That slowdown resulted from narrowing innovation. Even in the postwar years, innovation in Europe was feeble by past standards. In the aftermath of the financial crisis, much of Europe is still suffering a slump on top of its post-1990s fall. The slump will pass but the fall will not be easily overcome. The continent is losing its best talent. It needs to fight for an economic life worth living.
