Divorce doesnt necessarily make adults happy. But toughing it out in an unhappy marriageuntil it turns around just might do, a new study says.

The research identified happy and unhappy spouses. culled (选出 ) from a national database.Of the unhappypartners who divorced. about half were happy five years later. But unhappyspouses who stuck it out often did better. About two-thirds were happy five years later. Studyresults contradict what seems to be commonsense, says David Blankenhorn of the Institute forAmerican Values, a think-tank on the family. The institute helped sponsor the research leambased at the University of Chicago. Findings will be presented in Arlington, Va.. at the SmartMarriage conference. sponsored by the Coalition for Marriage. Families and CouplesEducation.

The study looked at data on 5,232 married adults from the National Survey of Families andHouseholds. It included .64.5 who were unhappy. The adults in the national sample wereanalyzed through 13 measures of psychological well being. Within the five years, 167 of theunhappy were divorced or separated and 478 stayedmarried.

Divorce didnt reduce symptoms of depression, raise self-esteem or increase sense ofmastery compared withthose who stayed married, the report says.

Results were controlled for factors including race, age, gender and income. Staying marrieddid not tend to trap unhappy spouses in violent relationships. What helped the unhappymarried turn things around To supplement the formal study data, the research team askedprofessional firms to recruit focus groups totaling 55 adults who were marriage survivors.All had moved from unhappy to happy marriages. These 55 once-discontented married felttheir unions got better via one of three

routes, the report says:

Marital endurance. Wich time, job situations improved, children got older or better. orchronic ongoing problems got put into new perspective. Partners did not work on theirmarriages.

Marital work. Spouses actively worked to solve problems, change behavior of improvecommunication.

Personal change. Partners found alternative ways to improve their own happiness and build agood and happy life despite a mediocre marriage. In effect the unhappy partner changed.

六级英语阅读专项练习答案

1.David Blankenhorn认为,人们通常认为_________。

A) 对于一段不美满的婚姻,离婚比勉强在一起是更好的解决方法。

B) 对于一段不美满的婚姻,离婚不一定是唯一的解决方法。

C) 要维系一段不美满的婚姻需要很大的勇气和容忍度。

D)要不要结束一段不美满的婚姻对于夫妻来说是一个很难做的决定。

[A]根据第2段第5句首先可以推断人们普遍的观点与研究结果相反。第2段开头四句表明坚持不离婚的人最终的情况会变得比离婚的人好,与此相反的观点即为:人们通常认为离婚比坚持不离婚好。因此选项A为本题答案。选项B 是本文的主题,研究的结果也支持这个说法,而人们普遍的看法应与此相反;第2段并没有讨沦如何才能维持婚姻,选项C是无关内容;本段对比了婚姻不幸福的人采取不同做法的结果,并没有讨论人们面临婚姻问题时内心的挣扎,因此选项D也是无关内容。

2. 下列关于正在讨论的研究哪一个是正确的

A) 研究是由David Blankenhorn任所长的美国价值观研究所主持的。

B) 研究是由婚姻、家庭和夫妻教育联盟资助的。

C) 研究对象选自基于芝加哥大学的全国数据库。

D) 研究报告会被纳入智慧婚姻大会的日程当中。

[D]第2段末句表明智慧婚姻会议的内容包括宣读研究报告,由此可见,选项D是对第2段末句的近义改写。第2段第6句表明选项A中提到的研究所赞助该研究,并非主持开展该研究,而且原文也没有表示David Blankenhorn是该研究所的领导,故A不正确;第2段段末sponsored by 引出的名词结构修饰的对象是智慧婚姻会议,它并没有赞助该研究,故选项B不对;database在第2段首句提到,the University of Chicago在第6句提到,它们之间并没有关系,选项C也不对。

3. 13项心理健康指标是用来__________。

A) 作为选择研究对象的标准

B) 作为帮助成年人解决不美满婚姻的方法

C) 检测所有的5232名已婚人士

D) 检测数据库中的所有成年人

[C]第3段第3句中的The adults in the national sample指的就是已被抽样出来的受试者,即指第3段首句提到过的5232 married adults,因此本题答案为选项C。第3段第3句表明这13项指标是用于分析the adults in the national sample的,言下之意,sample(subjects) 都已经选好了,因此选项A 的说法是错误的;该句也表示这13项指标是用于analyze受试者的,该段没有进一步说明如何帮助婚姻不幸福的夫妇克服困难,因此选项B不难确;本文的主题是婚姻状况,因此, 13项指标所分析的对象应该也与主题密切相关,不需要分析数据库中的所有成年人,只要关注有婚则状况的就行了,因此选项D覆盖范围过于宽泛,也不对。

4.形容作者对于离婚的态度最好的形容词是___________.

A) 批判的

B)客观的

C)模棱两可的

D)讽刺的

[B]首段的结构就像新闻报道的结构,将信息的来源放在了段末,指出本文将要介绍一项新研究的结果,其他段落的首句都含有research, study或report 等词,表明本文作者只是客观地转述研究的过程和结果,没有发表自己的见解,因此B正确。虽然本文显示,在遇到不快乐的婚姻的时候,离婚并不一定使人快乐,但不能因此说作者对离婚抱着批评或讽刺的态度,因为本文主要介绍了一项研究及其结果,因此选项A和D都不正确;作者引用了研究中的很多数据,而且客观地陈述了研究的结果,对divorce的任何评价都来自于那项研究,并没有武断地妄下结论,因此选项C也不正确。

5. 根据报告所称,婚姻不美满的人如果只是________也许不能挽救婚姻。

A) 坐等生活水平提高

B) 得到子女的理解

C) 改变自己对于平庸婚姻的态度

D) 着手解决自己的问题,加强沟通

[B]选项B在原文没有提及,虽然倒数第3段第2句也提到了有关children 的信息,但从该句不能推断出与understanding有关的任何信息,因此B符合本题题意。选项A概括了政善婚姻的第1条途径;选项D是第2途径;而选项C是第3条途径。

六级英语阅读专项练习附答案解析 Office workers who would normally step into a pub or gym to cope with the stress of a workingday are being invited instead to sit in front of a painting. Manchester Art Gallery has recruited two of the country's leading experts in stressmanagement to choose pictures that are guaranteed to leave even the most frantic feeling atease wich the world.They have created the "tranquility tour" which allows city-centre workersto spend their lunch hour taking a soothing tourof what are described as "some of the mostrelaxing and inspiring paintings ever committed to canvas”. The free tour takes the visitorthrough several centuries of painting, from the Victorian aesthetic movement.through thePreRaphaelite school, to modern abstract an. Kim Gowland, a gallery executive. said: "Looking at art is a stress-relieving activity. What weare tryingto do is encourage people who work in the city to spend half an hour of theirlunchbreak in the gallery. to chill out rather than rush around the shops." The five works chosen by Andrew Loukes. the gallery's manager, are: John Roddam SpencerStanhope’s The Waters of Lethe 1880, Turner's Thomson’s Aeolia n Harp 1809, Sir JohnEverett Millais’s Autumn Leaves 1856, James Durden’s Summer in Cumberland 1925 andBridget Riley’s Zephyr 1976. Mr. Loukes said: "We chose five pictures that suggest restfulness. We also wamed to displaythe breadth of the collection. We arc particularly strong in early-19th and early-20th-centuryBritish art." Their therapeutic powers have been endorsed by Olga Gregson and Terry Looker from theDepartment of Biological Sciences at Manchester Metropolitan University. Dr. Gregson said that"research shows that stress levels have reduced and moods changed for the better” whensubjects looked at paintings. "Although art appreciation is very much a matter of personal choice, it is true that some worksof art appeal to almost everyone, and that some paintings

1.Why Integrity Matters What Is Integrity? The key to integrity is consistency- not only setting high personal standards for oneself (honesty, responsibility, respect for others, fairness) but also living up to those standards each and every day. One who has integrity is bound by and follows moral and ethical (道德上的) standards even when making life's hard choices, choices which may be clouded by stress, pressure to succeed, or temptation. What happens if we lie, cheat, steal, or violate other ethical standards? We feel disappointed in ourselves and ashamed. But a lapse (缺失) of integrity also affects our relationships with others. Trust is essential in any important relationship, whether personal or professional. Who can trust someone who is dishonest or unfair? Thus integrity must be one of our most important goals. Risky Business We are each responsible for our own decisions, even if the decision, making process has been undermined by stress or peer pressure. The real test of character is whether we can learn from our mistake, by understanding why we acted as we did and then exploring ways to avoid similar problems in the future. Making ethical decisions is a critical part of avoiding future problems. We must learn to recognize risks, because if we can't see the risks we're taking, we can't make responsible choices. To identify risks, we need to know the rules and be aware of the facts. For example, one who doesn't know the rules a about plagiarism (剽窃) may accidentally use words or ideas without giving proper credit or one who fails to keep careful research notes may unintentionally fail to quote and cite sources as required. But the fact that such a violation is "unintentional" does not excuse the misconduct, Ignorance is not a defense. "But Everybody Does It" Most people who get in trouble do know the rules and facts but manage to fool themselves about the risks they're taking by using excuses: "Everyone else does it." "I'm not hurting anyone", or "I really need this grade." Excuses can get very elaborate: "I know I'm look at another's exam, even though I'm supposed to keep my eyes on my own paper, but that's not cheating because I’m just checking my answers, not copying." We must be honest about our actions and avoid excuses, if we fool ourselves into believing we're not doing anything wrong, we can't see the real choice we're making - and that leads to bad decisions. To avoid fooling yourself, watch out for excuses and try this test: Ask how you would feel if your actions were public and anyone could be watching over yore shoulder. If you'd rather hide your actions, that's an indication that you're taking a risk and rationalizing it to yourself. Evaluating Risks To decide whether a risk is worth taking, you must examine the consequences, in the future as well as right now, negative as well as positive, and to others as well as to yourself. Those who take risks they later regret usually focus on immolate benefits and simply haven't considered what might go wrong. The consequences of getting caught are serious and may include a "O" on a test or assignment, an "F" in the class, suspension (暂令停学) or dismissal from school and a ruined reputation. In fact, when you break a role or law, you lose control over your life and give others the power to impose punishment that you have no control over. This is an extremely vulnerable (脆弱的) position. There may be some matters of life and death or highest principle, which might justify such a risk, but there aren't many things that fall in this category. Getting Away with it - Or Not Those who don't get caught pay an even higher price. A cheater doesn't learn from the test, which deprives (剥夺) him her of an education. Cheating undermines confidence and independence: the cheater is a fraud, and knows that without dishonesty, he/she would have failed. Cheating destroys self-respect and integrity, leaving the cheater ashamed, guilty and afraid of getting caught. Worst of all, a cheater who doesn't get caught the first time usually cheats again, not only because he/she is farther behind, but also because it seems "easier." This slippery slope of eroding ethics and bigger risks leads only to disaster. Eventually, the cheater gets caught, and the later he/she gets caught, the worse the consequences. Cheating Hurts Other, Too Cheaters often feel invisible, as if their actions "don't count" and don't really hurt anyone. But individual choices have an intense cumulative (累积的) effect. Cheating can spread like a disease. Recent statistics suggest 30%or more of college students cheat. If a class is graded on a curve, cheating hurts others' grades. Even if there is no curve, cheating "poisons" the classroom, and others may feel pressured to join in. ("If I don't cheat I can't compete with those who do") Cheating also has a destructive impact on teachers. The real reward of goof teaching is seeing students learn. But a cheater says. "I'm not interested in what you're trying to teach, all I care about is stealing a grade, regardless of the effect on others." The end result is a destructive attack on the quality of your education. Finally, cheating can hurt the reputation of the university and harm those who worked hard for their degree.

英语六级考试阅读题专项练习及答案(最新6篇) 英语六级考试阅读题专项练习及答案篇一 It is doing something better than other people that makes us unique. Yet a surprising number of people still see individuality as a surface thing. They wear bright clothes, dye their hair strange colors and decorate their skin with tattoos (文身) to make some kind of social statement. The whole purpose of individuality is excellence. The people who comprehend the simple principle of being unique through performance make our entire political and economic system work. Those who invent, who improve, who know more about a subject than other people do, and who take something that doesn#39;t work and make it work—these people are the very soul of capitalism. Charles Kettering didn#39;t like the idea of cranking a car to make it start, so he invented the electric starter. Henry Ford figured out the assembly-line technique and made it possible to mass-produce automobiles. Lewis Waterman saw no need to go on dipping a pen into an inkwell, so he put the ink into the pen. George Westinghouse told the world how to stop a train, and Elisha Otis, inventor of the elevator, indirectly created the city skyline. These people understood that individualism means working at the top of one#39;s capacity. Fortunately, enough Americans have been inspired to do something with their uniqueness that we have developed in less than three centuries from a frontier outpost into not only a country of freedom but a country strong enough to protect that freedom. These people prized the notions of individuality and excellence above all things and thus kept the great machine functioning. The ones with the purple hair and the horrorable jewelry are just along for the ride, trying to be different and not knowing how to go about it. 1 The student who earns A#39;s on his report card has grasped the idea and has found the real meaning of individuality. So has the youngster who has designed his own spaceship, who paints pictures of the world around him, or who can name all the states and their capitals. According to the author unique individuals are persons who______. A. do something better than other people B. know more about a subject than other people C. excel others in work D. all of the above 2、People who regard individuality as a surface thing always do the following EXCEPT A. wearing bright clothes B. coloring their hair C. doing better than others D. decorating their skin with tattoos 3、Which is NOT TRUE according to the passage? A. Henry Ford invented assembly-line technique. B. Elisha Otis was the inventor of the lift C. George Westinghouse created cranks. D. Lewis Waterman put the ink into the pen. 4、It can be inferred from the passage that______. A. the real secret to being unique lies in our excellent work B. if we want to be different we#39;d gain more profit C the student who earns A#39;s on the report card has not grasped the real meaning of individuality

Increasingly, they are looking to the generic-drugs (普通药物) industry as a savior. InNovember Japans finance ministry issued a report complaining that the countrys use ofgenerics was less than a third of that in America or Britain. In the same month Canadascompetition watchdog criticized the countrys pharmacies for failing to pass on the savingsmade possible by the use of generic drugs. That greed, it reckoned, costs taxpayers nearlyC$1 billion a year. Then on November 28th the European Commission issued the preliminary results of itsyear-long probe into drug giants in the European Union. The report reached a damning~,though provisional, conclusion: the drugs firms use a variety of unfair strategies to protecttheir expensive drugs by delaying the entry of cheaper generic opponents. Though this initialreport does not carry the force of law (a final report is due early next year), it has caused muchcontroversy. Neelie Kroes, the EUs competition commissioner, says she is ready to takelegal action if the evidence allows.

Air-conditioning began to spread in industries as a production aid during World War Ⅱ. Today most Americans need to take air-conditioning for granted to homes, offices, factories, theatres, shops, studios, schools, hotels, and restaurants. But not everybody is aware that high cost and easy comfort are merely two of the effects of the vast cooling of American. In fact, air conditioning has substantially altered the countrys character and customs. Many of the byproducts are so conspicuous that they are scarcely noticed. To begin with, air-conditioning transformed the face of America by making possible those glassy, boxy, sealed-in skyscrapers. It has been indispensable, no less, to the functioning of sensitive advanced computers, whose high operating temperatures require that they be constantly cooled. . . It has, at will, forced families into retreating into families with closed doors and shut windows, reducing the interactions of neighborhood life. It is really surprising that the publics often noted withdrawal into self-pursuit and privacy has coincided with the historic spread of

英语六级阅读理解附答案解析

英语六级阅读理解附答案解析 Personality is to a large extent inherent-A-type parents usually bring about A-type offspring.But the environment must also have a profound effect,since if competition is important toIhe parents, it is likely to become a major factor in the lives of their children. One place where children soak up A-characteristics is school, which is, by its very nature, ahighly competitive institution. Too many schools adopt the "win at all costs" moral standardand measure their successby sporting achievements. The current passion for making childrencompete against their classmates or against the clock produces a two-layer system, in whichcompetitive A-types seem in some way better than theirB-type fellows. Being too keen to wincan have dangerous that Pheidippides,the firstmarathonrunner,dropped dead seconds after saying:"Rejoice,we conquer!" By far the worst form of competition in schools is the disproportionate emphasis onexaminations. It is a rare school that allows pupils to concentrate on those things they dowell. The merits of competition by examination are somewhat questionable, but competitionin the certain knowledge of failure is positively harmful. Obviously, it is neither practical nor desirabl that all A youngsters change into B's. The worldneeds A types, and schools have an important duty to try to fit a child's personality to hispossible future employment. It is top management. If the preoccupation of schools with academic work was lessened, more time might be spentteaching children surer values. Perhaps selection for the caring professions.especially medicine,could be made less by good grades in chemistry and more by such considerations assensitivity and sympathy. It is surely a mistaketo choose our doctors exclusively from A-typestock. B's are important and should be encouraged.
