未分类题Britains private schools are one of its most successful exports. The children of the wealthy【C1】______to them, whether from China, Nigeria or Russia: the number of foreign pupils rose by 1.4% in the last year alone. 【C2】______foreign students, whether educated in British private schools or elsewhere, are decreasingly likely to go to English universities. According to the Higher Education Funding Council for England, 307,200【C3】______students began their studies in the country in 2012-13, down from 312,000 two years earlier and the first【C4】______in 29 years. Student numbers from the rest of the EU fell—【C5】______a result of the increase in annual tuition【C6】______in England from ￡6,000 a year to ￡9,000. But【C7】______from India and Pakistan declined most sharply. 【C8】______the visa regime for private schools, which is extremely【C9】______(the Home Office counts private schools as favored sponsors), student visas have been tightened. Foreign students used to be allowed to work for up to two years after graduating. They now have only four months to find a job paying upwards of ￡20,600 if they want to stay in Britain. This change was【C10】______to deal with sham colleges that were【C11】______offering two-year work visas. But it seems to have put【C12】______serious students too. Nick Hillman of the Higher Education Policy Institute says the government has sent unclear messages about the sort of immigration it wants to【C13】______. An emphasis on holding down net immigration discourages young Indians and Pakistanis in particular. Australia and America, which have more【C14】______entry criteria for students, are becoming more favored【C15】______. Colin Riordan, Cardiff Universitys vice-chancellor, adds that Britains student-visa regime has become more burdensome and complicated【C16】______. As a result, Britain is losing out to other countries in the【C17】______for talent—an odd thing,【C18】______how often the prime minister bangs on about the 'global race'. Its unwelcoming stand will【C19】______its long-term prospects. And the【C20】______of foreign students from leading British private schools to American colleges may have another, somewhat happier, consequence: America might become rather better at cricket.【C1】A．flockB．turnC．devoteD．keep

未分类题A study of how older teenagers use social media has found that Facebook is 'not just on the slide, it is basically dead and buried' and is being replaced by simpler social networks such as Twitter and Snapchat. Young people now see the site as 'uncool' and keep their【C1】______live purely to stay in touch with older【C2】______among whom it remains popular. Daniel Miller, who worked on the research, wrote: 'Mostly they feel embarrassed even to be【C3】______with it.' This year marked the start of what looks likely to be a【C4】______decline of what had been the most popular social networking sites. Young people are turning away in crowds and【C5】______other social networks instead,【C6】______the worst people of all, their parents, continue to use the service. 'Where【C7】______parents worried about their children joining Facebook, the children now say it is their family that insists they stay there to【C8】______about their lives. Parents have worked【C9】______how to use the site and see it【C10】______a way for the family to remain connected【C11】______, the young are moving on to cooler things. What appears to be the most important factor in a young persons【C12】______to leave Facebook was【C13】______that your mum sends you a friend request.' A study observed 16- to 18-year-olds in eight countries for 15 months and found that Facebook use was in decline. Instead, young people are turning to simpler services like Twitter, Instagram, Snapchat and WhatsApp which Professor Miller【C14】______were 'no match' for Facebook【C15】______functionality. 'Most of the school children in our survey【C16】______that in many ways, Facebook is technically better than Twitter or Instagram. It is more【C17】______, better for photo albums, organising parties and more【C18】______for observing peoples relationships,' said Professor Miller, adding that 'efficient isnt always best' in【C19】______young users. WhatsApp has overtaken Facebook as the number one way to send messages, say the researchers, while Snapchat has gained in popularity in recent months by allowing users to send images which 'self-destruct' after a short period on the recipients phone in order to maintain【C20】______.【C1】A．profilesB．cataloguesC．historiesD．desires

未分类题Despite helping to record events, photos could damage our memories. Researchers found people who take pictures have【C1】______remembering what actually happened. This phenomenon has been named 'photo-taking impairment effect'. From childrens birthdays to that long-awaited family holiday, we all want to remember those【C2】______moments with a photograph.【C3】______if youre one of those people who cant stop【C4】______beware then—you could【C5】______forgetting it all in a flash. A study has found that taking too many photos may prevent us from forming detailed memories. Researchers from Harvard University, the University of Wisconsin-Madison and Columbia University in the U.S. recently found that many people now use the Internet【C6】______a memory. They claimed that when someone wants to know something they now use the Internet【C7】______an 'external memory' just as computers use an external hard【C8】______. The study continued that we are now so【C9】______on smartphones and laptops, we go into 'withdrawal when we cant find out something【C10】______'. Far from helping us to【C11】______the moment, it could mean we miss whats going on right in front of our noses. Researchers led a group of students around a museum and asked them to either photograph or try to remember certain works of art and historical【C12】______. The next day, their memory was tested. It showed they were【C13】______at recognizing objects they had photographed than those they had only looked at. They were also poorer at【C14】______details of the objects they had taken pictures of. Dr Linda Henkel, who conducted the study at Fair field University in Connecticut, said: 'People so often【C15】______out their cameras almost mindlessly. When people rely on technology to remember for them, it can have a【C16】______impact on how well they remember their【C17】______.' Previous studies have suggested that【C18】______old photos can help us remember, but only if we spend long enough doing it. 'In order to remember, we have to【C19】______and interact with the photos, rather than just【C20】______them,' said Dr Henkel.【C1】A．puzzleB．troubleC．difficultyD．fuss

未分类题Peek through the inspection windows of the nearly 100 three-dimensional (3D) printers quietly making things at RedEye, a company based in Minnesota, and you can catch a glimpse of how factories will work in the future. It is not simply that the machines run day and night【C1】______by just a handful of technicians.【C2】______it is what they are making that shows how this revolutionary production process is【C3】______the manufacturing mainstream. 3D printers make things by building them up, a layer at a time,【C4】______a particular material, rather than【C5】______it by cutting, drilling or machining—which is why the process is also called additive manufacturing. There are many ways in which this can be done, and with only a【C6】______adjustment of software each item can be different,【C7】______the need for costly retooling of machines. This has made 3D printing a【C8】______way to make one-off items, especially prototype parts, mock-ups, small mechanical【C9】______and craft items. And that is about all that 3D printers are good for,【C10】______the doubters. Chief among them is Terry Gou, the boss of Foxconn. He thinks 3D printing is just 'a trick' without any【C11】______value in the manufacture of real finished goods, and he has vowed to start spelling his name backwards if【C12】______wrong. Mr. Gou is right about one thing: additive manufacturing is not about to replace mass manufacturing.【C13】______the technology is improving, the finish and durability of some printed items can still【C14】______what producers require. And nor can 3D printers produce millions of【C15】______parts at low cost, as mass-production lines can.【C16】______3D printers have their【C17】______which is why they are starting to be used by some of the worlds biggest manufacturers, such as Airbus, Boeing, GE, Ford and Siemens. The market for 3D printers and【C18】______is small, but growing fast. Last year it was worth $2.2 billion worldwide, up 29% from 2011. As producers become more【C19】______with the technology, they are moving from prototypes to final【C20】______.【C1】A．designedB．attendedC．introducedD．bought
