Couples with children are more likely to find themselves trapped than those without, but both groups are increasingly finding it impossible to bear the cost of setting up different homes.“When we talk about Relate’s clients, we are not talking about people on low incomes. We’re talking about people in employment, on average to above-average incomes,” said Ruth Sutherland, the charity’s chief executive.Sutherland said the charity, which began life as the Marriage Guidance Council 75 years ago, had never seen this demographic of clients struggling with their finances to such an extent that moving into two homes and getting on with their lives was an impossibility.“These are people who could previously afford to move away from each other when their relationship broke down,” she added. “But now, they are stretched just to pay their mortgage (抵押贷款) on top of the rising cost of living. When their relationship breaks down, they find they can’t afford two mortgages, on top of the cost of running two homes.”Sutherland said that for parents, the cost of childcare was another devastating(毁灭性的) factor. Parents in the UK spend an average of 27% of their salary on childcare, compared with a European average of 13%. Twenty-five hours of nursery care a week for a child aged two or under costs on average £5,000 in England, rising to between £6,000 and £15,000 in London.“To pay for the increased child care demands that come with being a single parent has become a pipe dream for many people, even those in well-paid jobs,” said Sutherland.Richer couples could find themselves in the same predicament (困境) as the difficult economic climate continued, Suther land predicted. “I would not be surprised at all to see the problem creeping up the salary band,” she said. “This era of austerity (节俭) we’re in is not like other hard times we have lived through.“In the past, we’ve had a dip and then recovery, but now we’re in unknown territory about the length of time people are going to have to cope with debt, job insecurity, pressure from work and the mounting cost of childcare.“The only thing we know is that people are going to have to cope with these problems for lo nger than they would ever have done so before.”At least 40% of Relate counsellors said they were seeing more couples split up than two years ago, with money worries cited as a major cause.“It’s vital for the future of our children, and thus the future he alth of our nation, that estranged (疏远的) parents manage their separation well,” said Sutherland.“Children learn about relationships at home. If they see their parents undermining each other, arguing and being vindictive, then that’s the foundation on whic h they will build their own relationships. It’s not only the adults who, if stuck in a toxic situation, are going to be damaged.”Which is why, said Sutherland, she was so concerned by another finding in Relate’s survey: that separated couples are increasingly unable to afford to complete their counselling courses.At least 80% of counsellors said increasing numbers of clients were unable to afford to “properly start or conclude” their counselling programmes, despite being offered short, intensive courses of four to six sessions, charged from £6 to £45 an hour, depending on their income.Over 70% of Relate counsellors said money problems including debt, a lack of disposable income, unemployment and rising living costs had worsened for their clients in the last two years.Almost 90% of counsellors said money worries made their clients depressed, with 80% saying couples argued more as a result and 65% saying it affected their clients’ physical health.“Let’s all be clear about the real cost of austerity: the impact of being in a relationship that isn’t working is toxic. It is harmful to your children and it permeates every other aspect of your life,” said Sutherland. “If the government wanted to protect the mental health of the country, both now and in the futur e, they would target these cuts differently.”The rate of family breakdown in the UK was revealed in October statistics from the Department of Work and Pensions showing that 79% of children under one live with both birth parents. This drops to 55% by the time the children reach 15.Nearly a quarter of people have continued to live with a partner, or know someone who has, because they couldn’t afford to live apart, according to a 2010 report from Shelter. “We also know that relationship breakup is a major ca use of homelessness,” said Campbell Robb, chief executive of Shelter.The 2012 total cost of family breakdown to the UK was £44bn, up from £42bn in 2011, according to a recent study by the Relationships Foundation. The study looked at the cost of familybreakdown in five key areas of public policy: tax and benefits, housing, health and social care, civil and criminal justice, and education and young people not in education, employment or training (Neets). It concluded that the annual cost for each taxpayer was now £1,470.“The government’s austerity policies are making things worse, and it doesn’t make sense economically,” said Sutherland. “What we want is for them to do a relationship and family impact assessment for every policy they consider introducing.”Robb said the “shortage of affordable housing in this country is being felt further and further up the income scale”.“We’re hearing from couples moving in together too fast to help with housing costs but then unable to move out if things go wrong because they can’t afford to live on their own. This has a huge impact on people’s home lives,” he added.Robb said the housing crisis is “the result of … more and more people chasing fewer and fewer homes, which has pushed up house prices and rents far faster than wages have risen.“Our research also shows that more and more people are putting off having children because they can’t find an affordable home,” he said. “Something is badly wrong when people who are working hard still face a constant struggle to get a decent place to live.”Caroline Davey, director of policy at Gingerbread, the charity for single-parent families, said families in the low- to middle-income bracket were “increasingly struggling financially”. “When a couple separates this financial squeeze can make it impossible for them to forge new lives separately,” she said.“With wages stagnating, higher risk of redundancy, spiralling living costs, and many families without any savings to speak of, it can be simply unachievable for a separating couple to afford to run two homes rather than one. The only alternative for some families is to continue living in the same home but as separate households.”Davey warned: “This situation could become more commonplace in future as the financial downturn bites ev en harder on families across the income scale.”She added: “Action is needed across a number of areas, for example strengthening the role of local authorities in supporting access to private rented accommodation, reversing the harshest housing benefit cuts, and sustained job creation.”A spokeswoman for the Treasury said: “The government has taken action to help people with the cost of living, including freezing council tax and fuel duty and cutting income tax for 25 million people by raising the personal allowance. Action taken to reduce the deficit has helped to keep interest rates near record lows. And we have extended the offer of 15 hours free education and care a week for disadvantaged two-year-olds, to cover an extra 130,000 children.”1.

Read the passage carefully. Then answer the questions or complete the statements in the fewestpossible words. Please write your answers on Answer Sheet 2.Questions 47 to 51 are based on the following passage.America's for-profit colleges are under fire, and the Obama administration is preparing tough new regulations for them. Although recent scandals suggest higher education needs to be better regulated, discriminating against the for-profit sector could do wider damage.The notion that profit is too dirty a motive to be allowed in a business as fine as education is pervasive(普遍存在的). Even Britain's Conservatives, determined though they are to introduce radical educational reforms, have drawn the line at allowing for-profit schools to get state funding. America has generally been more liberal; and, with the state and non-profit colleges cutting back, the for-profit sector has been doing startlingly well. In 2008-09 some 3,000 for-profit colleges educated 3.2m students—59% more than three years earlier, and 11.7% of all students.Yet recent government reports suggest that some of these colleges have a troublingly familiar business model: selling a low-grade product to people who are paying with subsidised government loans. The Department of Education reported that most students at many of these universities were defaulting on their loans. Similarly, an investigation by the Government Accountability Office found that even leading for-profit colleges such as Kaplan and the University of Phoenix had engaged in dishonest practices to recruit students and encourage them to borrow large sums to pay for their courses.Among the most contentious (有争议的) of the new rules due to be introduced on November 1st is a “gainful employment” requirement that would make a course eligible for gover nment loans only if enough current or past students are repaying their loans. The for-profit colleges maintain that they have high drop-out rates because their students are poorer than those in the state and non-profit sector, and that the gainful-employment rule will simply reduce access to higher education for poorer people.Constructive suggestions are rare in a debate that has mixed a lot of rhetorical cant with a big principle. The cant is more obvious. The American right cites Barack Obama's proposals as another sign that he hates capitalism. Yet not only abuses plainly occurred but for-profit colleges are hardly poster children for free enterprise: they are already heavily regulated, not least because most of the loans to students are provided by the government. The left, from its non-profit redoubts, claims that these are big businesses exploiting the little guy.The principle? Concentrate on the quality of the education, not the ownership. All sorts of colleges seem to have been guilty of shabby marketing. They should be treated the same. Good rules should apply to non-profit and for-profit colleges alike. Singling out for-profits for special attention risks depriving students, and America at large, of the full benefits in innovation and cost-effectiveness that the profit motive has generally brought to higher education. That really would be “sociallydestructive”.47. In most people’s eyes, pursing profit in education is very _____________________.48. Though Britain’s Conservatives decide to take a big step in education reform, they refuse toprovide for-profit schools with _____________________.49. According to the Department of Education report, most students of many for-profit colleges failedto pay _____________________.50. According to the “gainful employment” requirement, what conditions must a course meet to getgovernment loans?51. The author thinks the profit motive brings in _____________________ to higher education.Section BDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet2 with a single line through the centre.Passage OneQuestions 52 to 56 are based on the following passage.“HAVE Americans become complacent (自满的) in the face of terrorism?” asks the Washington Post’s Juliet Eilperin. The answer appears to be a qualified yes:A Gallup poll released Monday —which was conducted early April —found zero percent of Americans volunteering “terrorism” as the country’s most important problem. Terrorism has ranked at 1 percent or below in six separate priorities polls conducted before the Monday Gallup poll, compared to above 20 percent in the year after the attacks against the World Trade Center and Pentagon....Julian Zelizer, a professor of history and public affairs at Princeton University, said the fact that Americans have not been on a heightened state of alert r ecently shows that “life just normalized after the attacks and following the creation of a rather elaborate counterterrorism program.”“That is the objective of effective policies,” Zelizer wrote in an e-mail.Nicely put. The relevant question here seems to be: should Americans become complacent in the face of terrorism? Or, to phrase it less provocatively: is "complacent" really the word we’re looking for here? How about "calm", "level-headed", or "judicious"? The bombing in Boston on Tuesday was gruesome, awful and pointless, and it naturally riveted the nation due to its attention-grabbing setting. But that kind of attention-grabbing setting is precisely what terrorists seek out, with the aim of distorting the public’s perceptions of the actual threat. Pl anting two bombs at the Boston Marathon is a sick, twisted act of mass murder, but it doesn’t necessarily augur(预示) any more widespread campaign of terrorism, and it doesn’t imply the need for major behavioural or policy changes.Unsurprisingly, there are those who would find it politically useful to plunge Americans back into a state of paranoia(妄想狂). Steve King, a conservative congressman from Iowa, is trying to figure out some way to use the bombing to stem the tide of immigration reform. Ms Eilperin i nterviews Orrin Hatch, a Republican senator from Utah, and finds him in old 2002 mode: “You’re dealing with evil people who are very hard to control, and frankly there are sleeper agents that we’ve found in the past that have been here for years, and they show up and you had no idea." Sleeper agents?I mean, there were those Russian ones, but frankly if the Kremlin wants to spend millions of rubles launching Anna Chapman’s modeling career, that doesn’t seem like anything the American people should be overly concerned about.So far, the response to the bombings has been admirable precisely because it has been rather low-key. Politicians and most news agencies have refrained from speculating on the identity of the bombers. People have been loth to draw far-reaching conclusions in the absence of data. If the American people can maintain that dispassionate attitude, it could go a long way towards reducing the incentive for people to commit acts of terrorism in the first place.52. Juliet Eilperin cited Monday’s Gallup poll results as evidence that ______.A) most Americans are deeply worried about the national securityB) people are still in great pain over the loss of their families in 9/11C) American people have become complacent in face of terrorismD) few people are satisfied with the current anti-terrorism campaign53. Terrorists exploded bombs in Boston with intent to ______.A) produce widespread fearB) attract national attentionC) influence government decisionsD) discourage foreign investment54. How does the author see the two bombings at the Boston Marathon?A) It shows that the whole country is in great danger now.B) It proves the failure of the past anti-terrorism campaign.C) It suggests that people should be alert to dangers around.D) It is not a sign that more terrorists attacks will happen.55. Steve King is trying to take advantage of the Boston bombing to ______.A) stop the immigration reformB) embarrass Democratic PartyC) raise public awareness about terrorismD) panic foreigners into leaving America56. What can help discourage people from commit acts of terrorism according to the author?A) Good media coverage of the events.B) Strict security checks on immigrants.C) Public staying calm facing terrorism.D) Government stopping foreign aid.Passage TwoQuestions 57 to 61 are based on the following passage.Given that a good year in the haute couture (高级定制女装) business is one where you lose even more money than usual, the prevailing mood in Paris last week was sensational. The big-name designers were falling over themselves to boast of how many outfits they had sold at below cost price, and how this proved that the fashion business was healthier than ever.Jean-Paul Gaultier reported record sales, "but we don't make any money out of it," the designer assured journalists backstage."No matter how successful you are, you can't make a profit from couture," explained Jean-Jacques Picart, a veteran fashion PR man, and co-founder of the now-bankrupt Lacroix house.Almost 20 years have passed since the Alice in Wonderland economics of the couture business were first exposed. Outraged that he was losing money on evening dresses costing tens of thousands of pounds, the couturier Jean-Louis Scherrer published a detailed summary of his costs. One outfit he described contained over half a mile of gold thread, 18,000 sequins(亮片), and had required hundreds of hours of hand-stitching in an atelier (制作室). A fair price would have been £50,000,。

它可以把尘土和一些轻小物体卷扬到空中，形成一个小尘柱，其直径在几米左右，持续时间只有几分钟。

③有一种风叫“焚（fén）风”，常出现在德国、奥地利、瑞士的山谷和我国新疆吐鲁番盆地等地区。
