单选题根据下面资料，回答题 What If You Could Learn Everything A.Imagine every student has a tireless personal tutor, an artificially intelligent and inexhaustible companion that knows everything, knows the student, and helps her learn what she needs to know. "'You guys sound like you're from the future,'" Jose Ferreira, the CEO of the education technology startup Knewton, says. "That's the most common reaction we get from others in the industry." B .Several million data points generated daily by each of 1 million students from elementary school through college, using Knewton's "adaptive learning" technology to study math, reading, and other fundamentals. Adaptive learning is an increasingly popular catchphrase denoting educational software that customizes its presentation of material from moment to moment based on the user's input. It's being hailed as a "revolution" by both venture capitalists and big, established education companies." C.Ferreira started Knewton in 2008 with more or less the same vision he believes in today: to enable digital technology to transform learning for everyone and to build the company that dominates that transformation."Look at what other industries the Internet has transformed," he once said. "It laid waste to media and is rebuilding it. But for whatever reason, people don't see it with education. It is blindingly obvious to me that it will happen with education. All the content behind education is going to move online in the next 10 years. It's a great shift. And that is what Knewton is going to power." D.The recommendation engine is a core technology of the Internet, and probably one you encounter every day. Google uses recommendations: other people who entered these search terms clicked on this page, so we'll show it to you first. Amazon uses them: other people who bought this book also bought that book. The more you use one of these websites, the more it knows about you—not just about your current behavior, but about all the other searches and clicks you've done. In theory, as you spend more time with a site its recommendations will become more personalized even as they also draw on everyone else's interactions within the platform. E.Knewton, at base, is a recommendation engine but for learning. Rather than the set of all Web pages or all movies, the learning data set is, more or less, the universe of all facts. For example, a single piece of data in the engine might be the math fact that a Pythagorean triangle has sides in the ratio 3:4:5, and you can multiply those numbers by any whole number to get a new set of side lengths for this type of triangle. Another might be the function of "adversatives" such as "but," "however," or "on the other hand" in changing the meaning of an English sentence. F. Ferreira calls these facts "atomic concepts," meaning that they're indivisible into smaller concepts—he clearly likes the physics reference.When a textbook publisher like Pearson loads its curriculum into Knewton's platform, each piece of content—it could be a video, a test question, or a paragraph of text--is tagged with the appropriate concept or concepts. G.Let' s say your school bought the Knewton-powered My Math Lab online system, using the specific curriculum, say, Lial's Basic College Mathematics 8e. When a student logs on to the system, she first takes a simple placement test or pretest from the book, which has been tagged with the relevant "atomic concepts." As a student reads the text or watches the video and answers the questions, Knewton's system is "reading" the student as well--timing every second on task, tabulating (把...列成表格.every keystroke, and constructing a profile of learning nick_info: hesitant or confident? Guessing blindly or taking her time? H.Based on the student's answers, and what she did before getting the answer, "we can tell you to the percentile, for each concept: how fast they learned it, how well they know it, how long they'll retain it, and how likely they are to learn other similar concepts that well," says Ferreira. By watching as a student interacts with it, the platform deduces. I. The platform forms a personalized study plan based on that information and decides what the student should work on next, feeding the student the appropriate new pieces of content and continuously checking the progress. A dashboard shows the student how many "mastery points" have been achieved and what to do next. Teachers, likewise, can see exactly which concepts the student is struggling with, and not only whether the homework problems have been done but also how many times each problem was attempted, how many hints were needed, and whether the student looked at the page or opened up the video with the relevant explanation. The more people use the system, the better it gets; and the more you use it, the better it gets for you. J.In a traditional class, a teacher moves a group of students through a predetermined sequence of material at a single pace. Reactions are delayed—you don't get homework or pop quizzes back for a day or two. Some students are bored; some are confused. You can miss a key idea, fall behind, and never catch up. Software- enabled adaptive learning flips all of this on its head. Students can move at their own speed. They can get hints and instant feedback. Teachers, meanwhile, can spend class time targeting their help to individuals or small groups based on need. K.Ferreira is able to work with competitors like Pearson and Wiley because his software can power anybody's educational content, the same way Amazon Web Services provides the servers for any website to be hosted in the cloud. But before it had any content partners, as a proof of concept, Knewton built its own remedial college math course using its software platform. Math Readiness was adopted starting in the summer of 2011 at Arizona State University; the University of Nevada, Las Vegas; and the University of Alabama. L.At ASU, students worked through the computer material in Knewton's Math Readiness program on their own or in small groups, with instructors spending face-to-face time working on problem solving, critical thinking, and troubleshooting specific concepts. After two semesters of use, course withdrawal rates dropped by 56 percent and pass rates went from 64 percent to 75 percent. At Alabama, pass rates rose from 70 percent to 87 percent, and at UNLV, where entering students were given the chance to take the course online in the summer before they started college, the percentage who then qualified for college algebra went from 30 percent to 41 percent. M."Before this, I worked on the assumption that all students were at the same place. Now, because they progress at different rates, I meet them where they are," Irene Bloom, a math lecturer at ASU, told an education blog about the pilot program. "I have so much more information about what my students do (or don't do.outside of class. I can see where they are stuck, how fast they are progressing, and how much time and effort they are putting into learning mathematics." N.The Knewton system uses its analytics to keep students motivated. If it notices that you seem to have a confidence problem, because you too often blow questions that should be easy based on previous results, it will start you off with a few questions you're likely to get right. If you're stuck, choosing the wrong answer again and again, it will throw out broader and broader hints before just showing you the right answer. It knows when to drill you on multiplication and when to give you a fun animated video to watch. O.It turns out that personalizing in this way can speed up learning. In the first year, 45 percent of ASU students in a 14-week course learned the material four weeks ahead of schedule. Better data is giving more options to the student who didn't succeed as well. Students may not yet know enough to pass the final exam, but a close read of their answers shows that they are making slow and steady progress. "In the past, those students would have dropped out of school," he says. In fact, the vast majority of students placed into remedial math at the nation's community colleges never get their degrees. "Instead, we were able to say, give them another semester and they'll get it. Their whole life has now changed." Under the help of the platform, a teacher knows thoroughly about a certain student's study and can see it in detail.

My Older BrotherMy brother is two years older than I am. Sometimes he's OK, but other times he is not. Yesterday, I couldn't unlock the front door because it was dark, and I couldn't see where the keyhole was. Did my brother help? No! He just told me how stupid I was. Last week, when I came back from the hairdresser's, he looked at me and laughed, "What have you done with your hair? Look. I can help you. Take this bag and pull it over your head."

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.
