Unless there was something 2 wrong with you, you wouldn“t be too happy about it, to say the 3 . I

16、t is all the more surprising therefore that so many parents in the world choose to 4 such abnormal conditions on their children. Any discussion of this topic 5 question the aims of education. 6 children“s heads full of knowledge is far from being the most important among them. One of the chief aims

17、of education is to equip future citizens with all they require to 7 in adult society. Now adult society is made up of men and women, so how can a segregated (隔离的) school possibly offer the right sort of preparation for it? Anyone entering adult society after years of segregation can only be in for a

18、 shock. A co-educational school offers children nothing less than a small, true 8 of society. Boys and girls are given the opportunity to get to know each other, to learn to live together from their earliest years. They are put in a position where they can compare themselves with each other in terms

19、 of 9 ability, athletic achievement and many of the extra 10 which are part of school life. In a co-educational school, everything falls into its proper place. But perhaps the greatest contribution of co-education is the healthy attitude to life it encourages. （分数：71.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填

It may sound counterintuitive (违反直觉的), but people who s

21、pend more of their day having deep discussions and less time engaging in small talk seem to be happier, said Matthias Mehl, a psychologist at the University of Arizona who published a study on the 1 . “We found this so interesting, because it could have gone the other wayit could have been, “Don“t w

22、orry, be happy“as long as you surf on the 2 level of life you“re happy, and if you go into the essential depths you“ll be unhappy,“ Dr. Mehl said. But, he 3 , deep conversation seemed to hold the 4 to happiness for two main reasons: both because human beings are driven to find and create 5 in their

23、lives, and because we are social animals who want and need to 6 with other people. “By engaging in meaningful conversations, we manage to impose meaning on a(n) 7 pretty chaotic world,“ Dr. Mehl said. “And interpersonally, as you find this meaning, you bond with your interactive partner, and we know

24、 that interpersonal connection and integration is a core 43 foundation of happiness.“ Dr. Mehl“s study was small and doesn“t 8 a cause-and-effect relationship between the kind of conversations one has and one“s happiness. But that“s the 9 next step, when he will ask people to increase the number of

25、deep conversations they have each day and cut back on small talk, and vice versa.

26、You Could Learn Everything?A. Imagine every student has a tireless personal tutor, an artificially intelligent and inexhaustible companion that magically 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

27、CEO of the education technology startup Knewton, says. “That“s the most common reaction we get from others in the industry.“ B. Four years ago, this kind of talk sounded like typical Silicon Valley boast from another childish founder of a technology startup. Today, Knewton says they can deliver the

28、kinds of breakthroughs: 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. Peter Thiel, the PayPal co-founder, Facebook investor, and an early

29、 investor in Knewton, told Knewton“s staff recently that the company has two key characteristics he looks for in a deal. “Before they happen, everybody thought it was impossible. Afterwards it“s too late for anyone else, because they“ve already done it.“ C. Adaptive learning is an increasingly popul

30、ar saying indicating 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. Starting this fall, Knewton“s technology will be available

31、 to the vast majority of the nation“s colleges and universities and K-12 school districts through new partnerships with three major textbook publishers: Pearson, MacMillan, and Houghton Mifflin Harcourt. And Ferreira“s done all this even though he says neither his investors nor his competition, to s

32、ay nothing of the public or the press, really understand what Knewton can do. D. But here“s the vision. Within 5 or 10 years, the paper textbook and mimeographed (油印的) worksheet will be dead. Classroom exercises and homeworktext, audio, video, gameswill have shifted entirely to the iPad or equivalen

33、t. And adaptive learning will help each user find the exact right piece of content needed, in the exact right format, at the exact right time, based on previous patterns of use. E. In an age of swelling class sizes, teacher layoffs, and students with a vast grouping of special needs and learning sty

34、les, some reformers greet these adaptive learning software systems as a savior that could make learning more customized and effective and teaching more efficient. While battle lines are sharp in K-12 school reform over issues from charters to the Common Core national curriculum standards, digital in

35、novations have fans across the political scope for their power to engage students and bring the classroom into the 21st century. F. Knewton, at base, is a recommendation engine but for learning. The recommendation engine is a core technology of the Internet, and probably one you encounter every day.

36、 Google uses recommendations: other people who entered these search terms clicked on this page, so we“ll show it to you first. The more you use one of these websites, the more it knows about younot just about your current behavior, but about all the other searches and clicks you“ve done. In theory,

37、as you spend more time with a site its recommendations will become more personalized. G. Rather than the set of all Web pages or all movies, the learning data set is, more or less, the universe of all facts. Ferreira calls these facts “atomic concepts,“ meaning that they“re indivisible into smaller

38、concepts. When a textbook publisher like Pearson loads its curriculum into Knewton“s platform, each piece of contentit could be a video, a test question, or a paragraph of textis tagged with the appropriate concept or concepts. H. The platform forms a personalized study plan based on that informatio

39、n 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 (仪表盘) shows the student how many “mastery points“ have been achieved and what to do next. Teachers, likewise, can see exactly which concep

40、ts the student is struggling with, and not only whether the homework problems have been done but also how many times each problem was attempted or how many hints were needed. The more people use the system, the better it gets; and the more you use it, the better it gets for you. I. In a traditional

41、class, a teacher moves a group of students through a predetermined sequence of material at a single pace. Reactions are delayedyou 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-e

42、nabled 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. J. The Knewton system uses its analytics to keep student

43、s 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

44、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. K. These are early days, and the questions are mounting. Research indicates that emotional qualities like courage, persistence, and

45、 motivation may be even more important to students“ success than the knowledge or skills they acquire, and they all depend heavily on human relationships. Knowledge acquisition is the only aspect of education that today“s digital technology seems especially well adapted to. So far, most software app

46、lications, platforms, apps, and games, including Knewton“s, have been optimized for transferring quantitative, bounded bodies of facts in fields like math, science, or engineering, as well as basic literacy and grammar. An adaptive-learning platform like Knewton“s is helpless to analyze a student“s

47、insight in class discussions, the special brilliance of an essay, or creativity in a group presentation. In a rare moment of modesty, Ferreira agrees. “In the end,“ he says, “maybe Knewton is just a tool.“（分数：71.00）(1).Students get personalized study plan and teachers get detailed information about
