单选题When it comes to jealousy, men and women aren't always on the same page. Previous studies have shown that, while men are more likely to see red over a partner's sexual infidelity, women are more upset by emotional cheating. Evolutionary psychologists- theorize that the difference is rooted in the sexes' historical roles--men wanted to guarantee that their partners were carrying their children, while women needed to feel secure that they and their children would be cared for by a committed partner. Yet, that evolutionary explanation doesn't account for a large group of men who say that emotional disloyalty is more upsetting than sexual infidelity, and women who are more upset by sexual betrayal. To gain a more thorough understanding of gender and jealousy, researchers from Pennsylvania State University (PSU) approached the issue with some modem psychology. In a study published in the journal Psychological Science, researchers found that, while generally speaking, the evolutionary explanation of gender and jealousy held up, when viewed through the lens of attachment theory--broadly, the psychological theory about our tendency to foster intimate relationships with other people--both men and women with secure emotional histories were more likely to experience jealousy over emotional infidelity, and those who were insecure or dismissing, were more likely to be vexed by sexual cheating. To tackle the issue, researchers recruited 416 college students from New York City, whose attachment styles were assessed through questionnaires containing a series of vignettes (short descriptions or pictures)--each reflecting either secure, fearful, preoccupied, or dismissing attachment styles. Participants were instructed to select the story that most accurately reflected their own attitude about romantic relationships, and were categorized accordingly. In a subsequent questionnaire, participants were asked whether they would be more upset by their partner "having passionate sexual intercourse with another person," or "forming a deep emotional attachment to another person." They found that, regardless of gender, 77.3% of securely attached participants viewed emotional infidelity as more upsetting, while 64.8% of insecure or dismissing participants thought sexual cheating was worse. These findings, the authors say, shed light on the intricate psychological nature of jealousy, and may help to develop techniques to determine the underlying dynamics of sexual jeaiousy--a well-documented cause of spousal abuse, beating and even murder. The authors suggest that, gaining a better understanding of not only the broad differ ences in jealousy between the sexes, but of the differences in jealousy within genders, may help to identify methods for interrupting abuse by fostering stable, secure attachments.

单选题With a series of well-timed deals, private-equity firms are giving traditional mediamanagers cause to be envious, The Warner Music transaction, in which Edgar Bronfman junior and three private-equity firms paid Time Warner $ 2.6 billion for the unit in 2003, is already judged a financial triumph for the buyers. Their success is likely to draw still more private-equity into the industry. And the investments are likely to get bigger: individual privateequity funds are growing—a $10 billion fund is likely this year—so even the biggest media firms could come within range, especially ff private-equity investors club together, Some private-equity firms have long put money in media assets, but mostly reliable, relatively obscure businesses with stable cash flows. Now, some of them are placing big strategic bets on the more volatile bits, such as music and movies. And they are currently far more confident than the media old guard that the advertising cycle is about to turn sharply upwards. One reason why private-equity is making its presence felt in media is that it has a lot of money to invest. Other industries are feeling its weight too. But private-equity's buying spree (狂购乱买) reveals a lot about the media business in particular. Media conglomerates (联合公司) lack the confidence to make big acquisitions, after the last wave of deals went wrong. Executives at Time Warner, for instance, which disastrously merged with AOL in 2000, wanted to buy MGM, a movie studio, but the board (it is said) were too nervous. Instead, private-equity firms combined with Sony, a consumer-electronics giant, to buy MGM late last year. Private-equity's interest also reflects the fact that revenue growth in media businesses such as broadcast TV and radio is now hard to come by. The average annual growth rate for 12 categories of established American media businesses in 1998-2003, excluding the internet, was just 3.4% , says Veronis Suhler Stevenson, an investment bank. Private-equity puts a higher value on low-growth, high cashflow assets than the public stockmarket, says Jonathan Nelson, founder of Providence Equity Partners, a media-focused private-equity firm. What private-equity men now bring to the media business, they like to think, is financial discipline plus an enthusiastic attitude towards new technology. Old-style media managers, claim the newcomers, are still in denial about how technology is transforming their industry. Traditional media managers grudgingly agree that, so far, private-equity investors are doing very nicely indeed from their entertainment deals. The buyers of Warner Music have already got back most of their $ 2.6 billion from the farm by cutting costs, issuing debt and making special payouts to shareholders. This year, its investors are expected to launch an initial public offering, which could bring them hundreds of millions more.

单选题Hippies were members of a youth movement of the 1960's and 1970's that started in the United States and spread to Canada, Great Britain, and many other countries. The hippies rejected the customs, traditions, and life styles of society and tried to develop those of their own. Most hippies came from white middle-class families and ranged in age from 15 to 25 years old. They thought too many adults cared about making money and little else. The term hippie may come from the word hip, which means "turned-in" or aware. Hippies wanted a world based on love of humanity and peace. Many believed that wonderful, magical changes were about to take place. They thought these changes would happen as soon as people learned to express their feelings honestly and to behave naturally at all times. Hippies strongly opposed U.S. involvement in the Vietnam War. Many hippies lived together in small groups, working with one another and sharing possessions. Others refused to be tied down to a fixed job or home. They wandered from place to place seeking part-time work and temporary shelter. Some begged for spare change and lived in the streets or camped in parks or other public lands. Hippies were sometimes called "flower children" because they gave people flowers to communicate gentleness and love. They let their hair grow long and walked barefoot or in sandals. Hippies attracted public attention by wearing clothing that featured unusual combinations of colors and textures. A large number of hippies used marijuana, LSD, and other drugs. Drug experiences shaped many of their symbols and ideas. The Beatles, a popular English rock group, helped spread the hippie movement with their song. Hippie favorites included such other rock groups as the Grateful Dead and the Jefferson Airplane, singers Joan Baez and Bob Dylan, poet Allen Ginsberg, and novelist Ken Kesey. Many hippies admired Timothy Leary, a psychologist who preached salvation through the use of drugs. In time, most hippies realized it was not easy to reform society by "dropping'out" of it. Some joined more organized political movements to work for specific social causes. Others turned to spirituality or religion. The majority simply left the hippie stage of their lives behind while trying to hold on to at least a few of the ideals that once inspired them.

单选题{{B}}Text 3{{/B}} When it comes to the slowing economy, Ellen Spero isn't biting her nails just yet. But the 47-year-old manicurist isn't cutting, filling or polishing as many nails as she'd like to, either. Most of her clients spend $12 to $50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I'm a good economic indicator," she says. "I provide a service that people can do without when they're concerned about saving some dollars. " So Spero is downscaling, shopping at middle-brow Dillard's department store near her suburban Cleveland home, instead of Neiman Marcus. "I don't know if other clients are going to abandon me, too" she says. Even before Alan Greenspan's admission that America's red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealerships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year's pace. But don't sound any alarms just yet. Consumers seem only mildly concerned, not panicked, and many say they remain optimistic about the economy's long-term prospects, even as they do some modest belt-tightening. Consumers say they're not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, "there's a new gold rush happening in the $4 million to $10 million range, predominantly fed by Wall Street bonuses," says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three," says John Tealdi, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks see silver linings to this slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn't mind a little fewer bubbles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan's hot new Alain Ducasse restaurant used to be impossible. Not anymore. For that, Greenspan ＆ Co. may still be worth toasting.

单选题{{B}}Text 3{{/B}} The "MyDoom" virus could presage a generation of computer attacks by organised gangs aiming to extract ransoms from online businesses, experts said yesterday. The warning came as the website run by SCO, a company that sells Unix computer software, in effect disappeared from the web under a blizzard of automated attacks from PCs infected by the virus, which first appeared a week ago. The "MyDoom-A" version of the virus is reckoned to be the worst to have hit the internet, in terms of the speed of its spread, with millions of PCs worldwide believed to be infected. Such "zombie" machines begin to send out hundreds of copies of the virus every hour to almost any e-mail address in their files. On Sunday they began sending automated queries to SCO's website, an attack that will continue until 12 February. The attack is the web equivalent of ringing the company's doorbell and running away a million times a second, leaving its computers unable to deal with standard requests to view its pages. "You have to wonder about the time limit," said Graham Cluley, senior technology consultant at the antivirus company Sophos. "Someone could go to SCO after the 12th and say, 'If you don't want this to happen again, here are our demands'." Raimund Genes, European president of the security software firm Trend Micro, said: "Such a programme could take out any major website on the internet. It's not terrorism, but it is somebody who is obviously upset with SCO" SCO has earned the enmity of computer users through a lawsuit it has filed against IBM. SCO claims ownership of computer code it says IBM put into the free operating system Linux, and is demanding licence fees and damages of $1bn. Mr. Cluley said: "It might be that whoever is behind this will say to SCO, 'if you don't want the next one to target you, drop the lawsuit'." SCO has offered $250,000 (￡140,000) for information leading to the arrest of the person or people who wrote and distributed MyDoom. Nell Barrett, of the security company Information Risk Management, said, "I would give a lot of credence to the idea of gangs using viruses to extort money. It's hard for law enforcement to track them down, because they're using machines owned by innocent people." A second variant of MyDoom will start attacking part of Microsoft's website later today. The antivirus company MessageLabs said it had blocked more than 16 million copies of the virus in transit over the net so far. But millions more will have reached their targets.
