It is worth 1 the extraordinary impact that his invention has had on the English language. Everyday words like google, unfriend and app simply d

17、idn“t exist in 1990. Even more words have had unexpected 2 in meaning in those two decades. If you had mentioned tweeting (小鸟的啁啾声) to an English-speaker a few years ago, he would have 3 you were talking about bird noises, not the use of the microblogging (微博) site Twitter. Long ago, if someone lived

18、 online, it didn“t mean they spent every 4 minute on the Internet, but that they travelled around with the rail network. And wireless still means, to anyone of a certain age, a radionot the system for 5 Internet pages without wires. “The Internet is an amazing 6 for languages,“ said David Crystal, h

19、onorary professor of linguistics at the University of Bangor. “Language itself changes slowly but the Internet has 7 the process of those changes so you notice them more quickly.“ English is a remarkably 8 language, and if words continue to be used for at least five years they generally end up in th

20、e Oxford English Dictionary. But less accepted are the peculiar dialects that have 9 among some users. For example, “LOLcat“ is a phonetic, grammatically-incorrect caption that 10 a picture of a cat, like “I“m in your bed sleeping.“ But according to Prof. Crystal, they are all little developments us

21、ed by a very small number of peoplethousands rather than millions. “Will they be around in 50 years“ time? I would be very surprised.“ （分数：71.00）填空项 1:_九、Part Reading Compr(总题数：0，分数：0.00)十、Section A(总题数：1，分数：35.50)Today nanotechnology (纳米技术) is still in a formative phase. Yet it is maturing rapidly.

22、 Between 1997 and 2005, investment in nanotech research and development by governments around the world 1 from $432 million to about $4.1 billion, and :corresponding industry investment exceeded that of governments by 2005. By 2015, products incorporating nanotech will contribute approximately $1 tr

23、illion to the global economy. Descriptions of nanotech typically characterize it purely in terms of the minute sizeassemblies between the size of an atom and about 100 molecular diameters (分子直径). That 2 makes it sound as though nanotech is merely looking to use infinitely smaller parts than conventi

24、onal engineering. But rearranging the atoms and molecules leads to new 3 . One sees a transition between the fixed behavior of individual atoms and molecules and the adjustable behavior of collectives. Thus, nanotechnology might better be viewed as the 4 of quantum theory (量子论) and other nano specif

25、ic phenomena to fundamentally control the properties and behavior of matter. The second stage, which began in 2005, focuses on active nanostructures that change their size, shape, conductivity or other properties during use. New drug delivery particles could release therapeutic (治疗的) molecules in th

26、e body only after they reached their 5 diseased tissues. Electronic components such as transistors and amplifiers with adaptive functions could be reduced to single, complex molecules. Starting around 2010, workers have been 6 expertise with systems of nanostructures, directing large numbers of intr

27、icate components to specified ends. One application could involve the guided self assembly of nanoelectronic components into three dimensional circuits and whole devices. Medicine could employ such systems to improve the tissue compatibility of implants, or perhaps even to build 7 organs. After 2015

28、, the field will include molecular nanosystems. Whereas biological systems are water based and markedly temperature sensitive, these molecular nanosystems will be able to operate in a far wider range of environments and should be much faster. Computers and robots could be reduced to 8 small sizes. N

29、ew interfaces linking people directly to electronics could change telecommunications. Over time, therefore, nanotechnology should benefit every industrial sector and health care field. Nanotech does, however, pose new challenges to risk governance as well. Internationally, more needs to be done to c

30、ollect the scientific information needed to resolve the 9 and to install the proper regulatory oversight. Helping the public to 10 nanotech soberly in a big picture that retains human values and quality of life will also be essential for this powerful new discipline to live up to its astonishing pot

Th

32、e Roma- philosopher Seneca may have put it best 2000 years ago: “To be everywhere is to be nowhere.“ Today, the Internet grants us easy access to unprecedented amounts of information. But a growing body of scientific evidence suggests that the Net, with its constant distractions and interruptions, i

33、s also turning us into disrupted and superficial thinkers. B. The picture emerging from the research is deeply troubling, at least to anyone who values the depth, rather than just the velocity (速度), of human thought. People who read text studded with links, the studies show, comprehend less than tho

34、se who read traditional linear text. People who watch busy multimedia presentations remember less than those who take in information in a more sedate (镇定的) and focused manner. People who are continually distracted by e-mails, alerts and other messages understand less than those who are able to conce

35、ntrate. And people who juggle (同时应会) many tasks are less creative and less productive than those who do one thing at a time. C. The common thread in these disabilities is dispersing our attention. The richness of our thoughts, our memories and even our personalities hinges on our ability to focus th

36、e mind and sustain concentration. Only when we pay deep attention to a new piece of information are we able to associate it “meaningfully and systematically with knowledge already well established in memory,“ writes the Nobel Prize winning neuroscientist (神经科学家) Eric Kandel. Such associations are es

37、sential to mastering complex concepts. D. When we“re constantly distracted and interrupted, as we tend to be online, our brains are unable to generalize the strong and expansive neural connections that give depth and distinctiveness to our contemplating. We become mere signal-processing units, quick

38、ly shepherding disjointed bits of information into and then out of short-term memory. E. In an article published in Science last year, Patricia Greenfield, a leading developmental psychologist, reviewed dozens of studies on how different media technologies influence our cognitive abilities. Some of

39、the studies indicated that certain computer tasks, like playing video games, can enhance “visual literacy skills“, increasing the speed at which people can shift their focus among icons and other images on screens. Other studies, however, found that such rapid shifts in focus, even if performed adep

40、tly, result in less rigorous and “more automatic“ thinking. F. In one experiment conducted at Cornell University, for example, half a class of students was allowed to use Internet-connected laptops during a lecture, while the other had to keep their computers shut. Those who browsed the Web performe

41、d much worse on a subsequent test of how well they retained the lecture“s content. While it“s hardly surprising that Web surfing would distract students, it should be a note of caution to schools that are wiring their classrooms in hopes of improving learning. G. Ms. Greenfield concluded that “every

42、 medium develops some cognitive skills at the expense of others.“ Our growing use of screen-based media, she said, has strengthened visual-spatial intelligence, which can improve the ability to do jobs that involve keeping track of lots of simultaneous signals, like air traffic control. But that has

43、 been accompanied by “new weaknesses in higher-order cognitive processes,“ including “abstract vocabulary, mindfulness, reflection, inductive problem solving, critical thinking, and imagination“. We“re becoming, in a word, shallower. H. In another experiment, recently conducted at Stanford Universit

44、y“s Communication between Humans and Interactive Media Lab, a team of researchers gave various cognitive tests to 49 people who do a lot of media multitasking and 52 people who multitask much less frequently. The heavy multitaskers performed poorly on all the tests. They were more easily distracted,

45、 had less control over their attention, and were much less able to distinguish important information from trivial. I. The researchers were surprised by the results. They had expected that the intensive multitaskers would have gained some unique mental advantages from all their on-screen juggling. Bu

46、t that wasn“t the case. In fact, the heavy multitaskers weren“t even good at multitasking. They were considerably less adept at switching between tasks than the more infrequent multitaskers. “Everything distracts them,“ observed Clifford Nass, the professor who heads the Stanford lab. J. It would be

47、 one thing if the ill effects went away as soon as we turned off our computers and cellphones. But they don“t. The cellular structure of the human brain, scientists have discovered, adapts readily to the tools we use, including those for finding, storing and sharing information. By changing our habi

48、ts of mind, each new technology strengthens certain neural pathways and weakens others. The cellular alterations continue to shape the way we think even when we“re not using the technology. K. The pioneering neuroscientist Michael Merzenich believes our brains are being “massively remodeled“ by our

49、ever-intensifying use of the Web and related media. In the 1970s and 1980s, Mr. Merzenich, now a professor emeritus at the University of California in San Francisco, conducted a famous series of experiments on primate brains that revealed how extensively and quickly neural circuits change in response to experience. When, for example, Mr. Merzenich rearranged the nerves in a monkey“s hand, the nerve cells in the animal“s sensory cortex quickly reorganized themselves to create a new
