单选题There comes a time when all monopolies falter. Think of telecoms operators or utilities, for example. For Google, too, its near-monopoly on search ads will someday end. The company is nowhere near this point yet, of course. But recently there have been signs that Google is no longer quite as untouchable as it once was. Start with online ads. The market for digital advertising has weakened recently. According to IAB, US digital ad spend grew 14 per cent in the second quarter. Not bad. But that was the lowest rate of growth in two years. More concerning still for Google is that search ads" share of the digital advertising pie has been shrinking since 2011. Google is still outgrowing the market —revenues from its own sites, including YouTube, grew 20 per cent in the most recent quarter. But the move away from search is starting to hurt: Bernstein estimates that Google search revenue growth slowed to 17 per cent. Google"s fastest-growing source of revenue has become its lower-margin " other" category, which includes sales from Google Play and is growing at 50 per cent a year. As ad dollars move away from search, Google has been losing share of the overall online advertising market to Facebook. In the US, eMarketer expects Google"s share of digital ads to fall from 40 per cent(2013), to 38 per cent(2014), to 34 per cent(2016). Facebook"s market share is expected to climb from 8 per cent to 11 per cent in the same period. Part of the problem is that search ads do not seem to be quite as successful on mobile(the fastest-growing part of digital ad spend)as on desktop. People do use search on phones—search is about half of mobile ad spending. But these ads appear to have less impact than targeted social media ads, and could fall off quickly as more effective forms of mobile advertising are found. Face-book, which has a higher ad market share on mobile than on desktop, has seen its click-through rate triple over the past year, according to Nanigans. Unfortunately for Google, mobile advertising is getting increasingly crowded. Snapchat, a popular photo-sharing app, is launching ads. And Yahoo is trying to boost its mobile ad offering with its acquisition of Flurry. The search business naturally tends towards monopoly. But the advertising business, ex-search, does not.

单选题Passage One Most students arrive at college using" discrete, concrete and absolute categories to understand people, knowledge, and values. " These students live with a dualistic view, seeing "the world in polar terms of we-right-good vs. other-wrong-bad. " These students cannot acknowledge the existence of more than one point of view toward any issue. There is one "right" way. And because these absolutes are assumed by or imposed on the individual from external authority, they cannot be personally substantiated or authenticated by experience. These students are slaves to the generalizations of their authorities. An eye for an eye! Capital punishment is apt justice for murder. The Bible says so. Most students break through the dualistic stage to another equally frustrating stage—multiplicity. Within this stage, students see a variety of ways to deal with any given topic or problem. However, while these students accept multiple points of view, they are unable to evaluate or justify them. To have an opinion is everyone's right. While students in the dualistic stage are unable to produce evidence to support what they consider to be self-evident absolutes, students in the multiplistic stage are unable to connect instances into coherent generalizations. Every assertion, every point, is valid. In their democracy they are directionless. Capital punishment? What sense is there in answering one murder with another? The third stage of development finds students living in a world of relativism. Knowledge is relative: right and wrong depend on the context. No longer recognizing the validity of each individual idea or action, relativists examine everything to find its place in an overall framework. While the multiplist views the world as unconnected, almost random, the relativist seeks always to place phenomena into coherent larger patterns. Students in this stage view the world analytically. They appreciate authority for its expertise, using it to defend their own generalizations. In addition, they accept or reject ostensible authority after systematically evaluating its validity. In this stage, however, students resist decision making. Suffering the ambivalence of finding several consistent and acceptable alternatives, they are almost overwhelmed by diversity and need means for managing it. Capital punishment is appropriate justice—in some instances. In the final stage students manage diversity through individual commitment. Students do not deny relativism. Rather they assert an identity by forming commitments and assuming responsibility for them. They gather personal experience into a coherent framework, abstract principles to guide their actions, and use these principles to discipline and govern their thoughts and actions. The individual has chosen to join a particular community and agrees to live by its tenets. The accused has had the benefit of due process to guard his civil rights, a jury of peers has found him guilty, and the state has the right to end his life. This is a principle my community and I endorse.

单选题TEXT A Children as young as four will study Shakespeare in a project being launched today by the Royal Shakespeare Company. The RSC is holding its first national conference for primary school teachers to encourage them to use the Bard's plays imaginatively in the classroom from reception classes onwards. The conference will be told that they should learn how Shakespearian characters like Puck in A Midsummer Night's Dream are "jolly characters" and how to write about them. At present, the national curriculum does not require pupils to approach Shakespeare until secondary school. All it says is that pupils should study "texts drawn from a variety of cultures and traditions" and "myths, legends and traditional stories". However, educationists at the RSC believe children will gain a better appreciation of Shakespeare if they are introduced to him at a much younger age. "Even very young children can enjoy Shakespeare's plays," said Mary Johnson, head of the learning department. "It is just a question of pitching it for the age group. Even reception classes and key stage one pupils (five-to-seven-year-olds) can enjoy his stories. For instance, if you build up Puck as a character who skips, children of that age can enjoy the character. They can be inspired by Puck and they could even start writing about him at that age. " It is the RSC's belief that building the Bard up as a fun playwright in primary school could counter some of the negative images conjured up about teaching Shakespeare in secondary schools. Then, pupils have to concentrate on scenes from the plays to answer questions for compulsory English national-curriculum tests for 14-year-olds. Critics of the tests have complained that pupils no longer have the time to study or read the whole play and therefore lose interest in Shakespeare. However, Ms. Johnson is encouraging teachers to present 20-minute versions of the plays—a classroom version of the Reduced Shakespeare Company's Complete Works of Shakespeare (Abridged) which told his 37 plays in 97 minutes—to give pupils a flavour of the whole drama. The RSC's venture coincides with a call for schools to allow pupils to be more creative in writing about Shakespeare. Professor Kate McLuskie, the new director of the University of Birmingham's Shakespeare Institute—also based in Stratford—said it was time to get away from the idea that there was "a right answer" to any question about Shakespeare. Her first foray into the world of Shakespeare was to berate him as a misogynist in a 1985 essay but she now insists this should not be interpreted as a criticism of his works—although she admits: "I probably wouldn't have written it quite the same way if I had been writing it now. What we should be doing is making sure that someone is getting something out of Shakespeare," she said. "People are very scared about getting the right answer. I know it's difficult but I don't care if they come up with a right answer that I can agree with about Shakespeare. /
