单选题The golden rule for good writing is not a rule of grammar. It is true that there are rules of grammar, as in music there are rules of harmony, and that they are important, but one can no more write good English merely by keeping these rules than one can compose good music. The golden rule for good writing concerns not merely the arrangement of words but the choice of them. Only the right words can convey the right meaning: the secret is to pick those words and to use them and them only. For the "right" words have a happy knack (a clever way) of arranging themselves for you. But, first, you must have something to say. Matthew Arnold once said: "Have something to say and say it as clearly as you can. That is the only secret of style." There is much truth in those words, especially in relation to the sort of writing where emotional appeal plays no part. We can turn to the member of the General Post Office who, by composing the notice "Postal officials are neither bound to give change nor authorized to demand it." used thirteen words hardly less efficiently to warn customers of what must have been as intractable (difficult to deal with) dilemma. Every word is exactly right; no other word would do as well; each is pulling its weight: none would be dispensed with. As was said of Milton' s prose. "Fewer words would not have served the turn, more would have been superfluous./

单选题There are many benefits to using online distance learning environments. Online education is available any place, any time for global communities of learners based on shared interests. Online education with its group-based instruction and computer mediated communication provides an opportunity for new development and understanding in teaching and learning. Computer mediated communication encourages collaborative learning by not providing cues regarding appearance, race, gender, education, or social status, bestowing a sort of anonymity to participants. Distance also permits the expression of emotion (both positive and negative) and promotes discussion that normally would be inhibited. Yet, this same text-based positive aspect of online learning makes online education more cumbersome and therefore takes more time than face-to-face learning. In addition, the sheer bulk of messages can be overwhelming. The learner 0nly has the written text and no other non-verbal cues. This may confuse the learner and cause misunderstanding. Some students are not willing to take the time to go in and look up homework assignments and other online learning activities. ESL students shy away from online classes. They have expressed fear of having their work, viewed by others. In the road to dotcom in education, educators "have to slow down from their busy lives to be free to focus first on connecting with learners and connecting them to learning before they end up feeling like they are no longer using technology, but are being used by it". There is pressure to keep up with the times as well as "a cost-of-entry issue regarding technology in education. Without a certain level of technology services and learning options, many students will not consider attending a certain institution". Mark Milliron claims that "any technology has to prove that it will ultimately improve or expand learning". This will come about if educators "slow down, look around, and get on the road to dotcom—a place to thoughtfully engage and explore all aspects of technology, good, bad, or indifferent... A place with mindful focus on the people and passions that make life worth living". Should online learning be an issue of control or should students be convinced of its value as an authentic learning tool? Fear and a threatening environment don't enhance learning according to brain-based learning research. "How students feel about a learning situation determines the amount of attention they devote to it." "Positive emotions ensure that learning will be retained." It's very. important to discuss with students how they feel about technology and online learning so that they feel good about what they are doing. The process of implementing online distance learning is a slow and delicate one. Change will eventually come about but it will take time.

单选题"Gangnam Style", the ______ popular song from South Korean recording artist PSY has just become the most watched video on YouTube ever.

单选题The initial impact of computers was in the area of entertainment. If you walked by a video arcade in the early 1980s, you could not have failed to notice that the use of video games was growing at what some considered an alarming rate. In 1981 the movie industry grossed $3 billion, video games took in an estimated $6 billion. That gives you some idea of just how big the computer industry bad become. Video games employ the same technology as personal computers, and indeed many who bought personal computers did so primarily for playing games at home, thus saving their quarters. Though video games are not as popular as they were a few years ago, they did provide consumers with their first real reason to buy PCs. A more recent computer innovation, desktop publishing, supplies one good reason for those who write for a living to buy a PC. Desktop publishing is a deceptively simple description for an extremely complex group of hardware and software tools. You can now write text, edit text, draw illustrations, incorporate photographs, design page layouts, and print a finished document with a relatively inexpensive computer and laser printer. Although the new technology offers new freedom, there is a price to be paid for this freedom. With total control comes total responsibility. In fact, the issue of social responsibility in our new computer age has long been a topic of debate among computer enthusiasts. Some people are concerned with the long-term social effects of the so-called computer revolution. Ironically, many PC pioneers who built and marketed the first machines were 60s-style advocates of social change. They claim that while personal computer technology has the potential to make society more equal, it's having the opposite effect since upper-middle-class people can afford them and lower-class people cannot. In addition, the ways that computers are used to monitor the activities of their users have evoked anxiety about the machine. Over 7 million Americans now have their work paced, controlled, and monitored by computers. A computer is more restrictive and powerful in the way it controls people than the old-fashioned assembly line. This can lead to what some have called "tech-stress". Irritated eyes, back problems, and other physical symptoms have also been associated with the extensive use of computers. Although the personal computer may not have had the impact some predicted a decade ago, the combination of computer technology with satellites and cable does promise innovations in the mass media that would have seemed astonishing just a few short years ago.

单选题 For the past several years, the Sunday newspaper supplement Parade has featured a column called "Ask Marilyn". People are invited to query Marilyn vos Savant, who at age 10 had tested at a mental level of someone about 23 years old; that gave her an IQ of 228-the highest score ever recorded. IQ tests ask you to complete verbal and visual analogies, to envision paper after it has been folded and cut, and to deduce numerical sequences, among other similar tasks. So it is a bit confusing when vos Savant fields such queries from the average Joe (whose IQ is 100) as, What's the difference between love and fondness? or what is the nature of luck and coincidence? It's not obvious how the capacity to visualize objects and to figure out numerical patterns suits one to answer questions that have eluded some of the best poets and philosophers. Clearly, intelligence encompasses more than a score on a test. Just what does it means to be smart? How much of intelligence can be specified, and how much can we learn about it from neurology, genetics, computer science and other fields? The defining term of intelligence in humans still seems to be the IQ score, even though IQ tests are not given as often as they used to be. The test comes primarily in two forms: the Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scales (both come in adult and children's version). Generally costing several hundred dollars, they are usually given only by psychologists, although variations of them populate bookstores and the World Wide Web. Superhigh scores like vos Savant's are no longer possible, because scoring is now based on a statistical population distribution among age pecks, rather tan simply dividing the mental are by the chronological age and multiplying by 100. Other standardized tests, such as the Scholastic Assessment Test (SAT) and the Graduate Record Exam (GRE), capture the main aspects of IQ tests. Such standardized tests may not assess all the important elements necessary to succeed in school and in life, argues Robert J. Sternberg. In his article "How Intelligent Is Intelligence Testing?". Steinberg notes that traditional tests best assess analytical and verbal skills but fail to measure creativity and practical knowledge, components also critical to problem solving and life success. Moreover, IQ tests do not necessarily predict so well once populations or situations change. Research has found that IQ predicted leadership skills when the tests were given under low-stress conditions, but under high-stress conditions, IQ was negatively correlated with leadership--that is it predicted the opposite. Anyone who has toiled through SAT will testify that test-taking skill also matters, whether it's knowing when to guess or what questions of skip.
