15、分数：35.00)Nearly a third of women are the main breadwinners in their household in Britain, according to a major survey. Researchers said that in many relationships it was no longer assumed that the man would bring in the bigger income, 1 in a time of widespread redundancies (裁员). In a 2 shift in atti

16、tudes, four out of ten women said that the career of whichever partner had the highest income would take 3 in the relationship. In one in ten families, a house husband looks after the children and does the 4 while their female partner works full time. Ten percent of women admitted this role 5 had pu

17、t strains on their relationship and some said it had even led to them 6 company. The Women and Work Survey 2014, commissioned (受委托) by Grazia magazine, found that almost half of full-time mothers 7 not earning their own money. And two thirds of the mothers among the 2,000 women in the survey said th

18、ey wanted to keep working in some way after having children. A 8 higher number of those with children under three said they would prefer to workpreferably part-timerather than stay at home. Victoria Harper of Grazia said, “Women are getting good jobs when they graduate, and working up the career 9 f

20、sliked N. fluidity O. significant（分数：35.00）十三、Section B(总题数：1，分数：70.00)Robot ManagementA. Robots have been the stuff of science fiction for so long that it is surprisingly hard to see them as the stuff of management fact. A Czech playwright, Karel Capek, gave them their name in 1920 (from the Slavon

21、ic word for “work“). An American writer, Isaac Asimov, confronted them with their most memorable dilemmas. Hollywood turned them into superheroes and supervillains. When some film critics drew up lists of Hollywood“s 50 greatest good guys and 50 greatest baddies, the only character to appear on both

22、 lists was a robot, the Terminator. B. It is time for management thinkers to catch up with science-fiction writers. Robots have been doing auxiliary jobs on production lines since the 1960s. The world already has more than 1m industrial robots. There is now an acceleration in the rates at which they

23、 are becoming both cleverer and cheaper: an explosive combination. Robots are learning to interact with the world around them. Their ability to see things is getting ever closer to that of humans, as is their capacity to ingest information and act on it. Tomorrow“s robots will increasingly take on d

24、elicate, complex tasks. And instead of being imprisoned in cages to stop them colliding with people, they will be free to wander. C. America“s armed forces have blazed a trail here. They now have no fewer than 12,000 robots serving in their ranks. Peter Singer, of the Brookings Institution, a think-

25、tank (智囊团), says mankind“s 5,000-year monopoly on the fighting of war is breaking down. Recent additions to the battlefield include tiny “insects“ that perform reconnaissance (侦查) missions and giant “dogs“ to terrify enemies. The Pentagon is also working on the EATR, a robot that fuels itself by eat

26、ing whatever biomass (生物量) it finds around it. D. But the civilian world cannot be far behind. Who better to clean sewers or suck up nuclear waste than these remarkable machines? The Japanese have made surprisingly little use of robots to clear up after the recent earthquake, given their world leade

27、rship in this area. They say that they had the wrong sort of robots in the wrong places. But they have issued a global call for robotic assistance and are likely to put more robots to work shortly. E. As robots advance into the service industries they are starting to look less like machines and more

28、 like living creatures. The Paro (made by AIST, a Japanese research agency) is shaped like a baby seal and responds to attention. Honda“s robot, ASIMO, is humanoid and can walk, talk and respond to commands. F. Until now executives have largely ignored robots, regarding them as an engineering rather

29、 than a management problem. This cannot go on: robots are becoming too powerful and ubiquitous (无处不在的). Companies may need to rethink their strategies as they gain access to these new sorts of workers. Do they really need to outsource production to China, for example, when they have clever machines

30、that work ceaselessly without pay? They certainly need to rethink their human-resources policiesstarting by questioning whether they should have departments devoted to purely human resources. G. The first issue is how to manage the robots themselves. Asimov laid down the basic rule in 1942: no robot

31、 should harm a human. This rule has been reinforced by recent technological improvements: robots are now much more sensitive to their surroundings and can be instructed to avoid hitting people. But the Pentagon“s plans make all this a bit more complicated: many of its robots will be, in essence, kil

32、ling machines. H. A second question is how to manage the homo side of homo-robo relations. Workers have always worried that new technologies will take away their livelihoods, ever since the original Luddites“ fears about mechanised looms. That worry takes on a particularly intense form when the mach

33、ines come with a human face: Capek“s play that gave robots their name depicted a world in which they initially brought lots of benefits but eventually led to mass unemployment and discontent. Now, the arrival of increasingly humanoid automatons in workplaces, in an era of high unemployment, is bound

34、 to provoke a reaction. I. So, companies will need to work hard to persuade workers that robots are productivity-enhancers, not just job-eating aliens. They need to show employees that the robot sitting alongside them can be more of a helpmate than a threat. Audi has been particularly successful in

35、introducing industrial robots because the carmaker asked workers to identify areas where robots could improve performance and then gave those workers jobs overseeing the robots. Employers also need to explain that robots can help preserve manufacturing jobs in the rich world: one reason why Germany

36、has lost fewer such jobs than Britain is that it has five times as many robots for every 10,000 workers. J. These two principlesdon“t let robots hurt or frighten peopleare relatively simple. Robot scientists are tackling more complicated problems as robots become more sophisticated. They are keen to

37、 avoid hierarchies (层级) among rescue-robots (because the loss of the leader would render the rest redundant). So they are using game theory to make sure the robots can communicate with each other in egalitarian (平等) ways. They are keen to avoid duplication between robots and their human handlers. So

38、 they are producing more complicated mathematical formulae in order that robots can constantly adjust themselves to human intentions. This suggests that the world could be on the verge of a great management revolution: making robots behave like humans rather than the 20th century“s preferred option,

39、 making humans behave like robots.（分数：70.00）(1).Tomorrow“s robots will be free to move around rather than being locked up in cages so as not to hurt people.（分数：7.00）(2).It is not easy for people to regard robots as management stuff, for the later are mostly seen in science fictions.（分数：7.00）(3).Robo

40、ts appear more like living creatures as they enter into the service industry.（分数：7.00）(4).According to the Pentagon“s plans, many of its robots will essentially become killing machines.（分数：7.00）(5).The Japanese didn“t use a lot of robots to clear up after the recent earthquake, considering their wor

41、ld leadership in the robot field.（分数：7.00）(6).Companies should show their workers that robots can be more of a helper rather than a threat to them.（分数：7.00）(7).The fact that more and more human-like robots are used in workplaces will surely arouse reaction in a time of high unemployment.（分数：7.00）(8)

42、.Robots, who are considered as an engineering instead of a management problem, have been largely neglected by executives.（分数：7.00）(9).Scientists are trying to enable robots to constantly adjust themselves to people“s intentions.（分数：7.00）(10).The example that Germany has lost fewer manufacturing jobs

43、 than Britain shows that robots can help preserve manufacturing jobs in the rich world.（分数：7.00）十四、Section C(总题数：0，分数：0.00)十五、Passage One(总题数：1，分数：72.00)Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time: if corrected too much, he will

44、 stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people“s. In the same way, when children learn to do all the other things they learn to do wi

45、thout being taught to walk, run, climb, whistle, ride a bicyclecompare those performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his own mistakes for himself, let alone correct them. We do it all for him. We act

46、 as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Soon he becomes dependent on the teacher. Let him do it himself. Let him work out, with the help of other children if he wants it, what this word says, what answer is to that

47、 problem, whether this is a good way of saying or doing this or not. If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine work? Our job should be to help the child when

48、he tells us that he can“t find the way to get the right answer. Let“s end this nonsense of grades, exams, marks. Let us throw them all out, and let the children learn what all educated persons must someday learn, how to measure their own understanding, how to know what they know or do not know. Let

49、them get on with this job in the way that seems most sensible to them, with our help as school teachers if they ask for it. The idea that there is a body of knowledge to be learnt at school and used for the rest of one“s life is nonsense in a world as complicated and rapidly changing as ours. Anxious parents and teachers say, “But suppose they fail to learn something essential, something they will need to get in the world?“ Don“t worry! If it is essential, they will go out into the world and
