单选题 The Alzheimer's Association and the National Alliance for Caregiving estimate that men make up nearly 40 percent of family care providers now, up from 19 percent in a study conducted by the Alzheimer's Association a decade ago. About 17 million men are caring for an adult. Women still provide the bulk of family care, especially intimate tasks like bathing and dressing. Many complain that their brothers are treated like heroes just for showing up. But with smaller families and more women working full-time, many men have no choice but to take on roles that would have been alien to their fathers. Often they are overshadowed by their female counterparts and faced with employers, friends, support organizations and even parents who view caregiving as an essentially female role. Male caregivers are more likely to say they feel unprepared for the role and become socially isolated, and less likely to ask for help. 'Isolation affects women as well, but men tend to have fewer lifeline. They are less likely to have friends going through similar experiences, and depend more on their jobs for daily human contact.' Dr. Donna Wagner, the director of gerontology (老年学) at Towson University and one of the few researchers who has studied sons as caregivers, said. In past generations, men might have pointed to their accomplishments as breadwinners or fathers. Now, some men say they worry about the conflict between caring for their parents and these other roles. In a study at three Fortune 500 companies, Dr. Donna Wagner found that men were less likely to use employee-assistance programs for caregivers because they feared it would be held against them. 'Even though the company has endorsed the program, your supervisors may have a different opinion.' Dr. Wagner said. Matt Kassin, 51, worked for a large company with very generous benefits, and his employer had been understanding. But he was reluctant to talk about his caregiving because he thought 'when they hire a male, they expect him to be 100 percent focused.' And he didn't want to appear to be someone who had distractions that detracted (破坏) from performance. For many men, the new role means giving up their self-image as experts, said Louis Colbert, director of the office of services for the aging in Delaware County, Pa., who has shared care of his 84-year-old mother with his siblings since her Alzheimer's made it necessary. Once a year, Mr. Colbert organizes a get-together for male caregivers. The concerns they raise, he said, are different from those of women in support groups. 'Very clearly, they said they wanted their roles as caregivers validated, because in our society, as a whole, men as caregivers have been invisible,' he said.

单选题Gordon Shaw the physicist, 66, and colleagues have discovered what's known as the "Mozart effect," the ability of a Mozart sonata, under the right circumstances, to improve the listener's mathematical and reasoning abilities. But the findings are controversial and have launched all kinds of crank notions about using music to make kids smarter. The hype, he warns, has gotten out of hand. But first, the essence: Is there something about the brain cells work to explain the effect? In 1978 the neuroscientist Vernon Mountcastle devised a model of the neural structure of the brain's gray matter. Looking like a thick band of colorful bead work, it represents the firing patterns of groups of neurons. Building on Mounteastle, Shaw and his team constructed a model of their own. On a lark, Xiaodan Leng, who was Shaw's colleague at the time, used a synthesizer to translate these patterns into music. What came out of the speakers wasn't exactly toe-tapping, but it was music. Shaw and Leng inferred that music and brain-wave activity are built on the same sort of patterns. "Gordon is a contrarian in his thinking," says his longtime friend, Nobel Prize-winning Stanford physicist Martin Peri. "That's important. In new areas of science, such as brain research, nobody knows how to do it." What do neuroscientists and psychologists think of Shaw's findings?' They haven't condemned it, but neither have they confirmed it. Maybe you have to take them with a grain of salt, but the experiments by Shaw and his colleagues are intriguing. In March a team led by Shaw announced that young children who had listened to the Mozart sonata and studied the piano over a period of months improved their scores by 27% on a test of ratios and proportions. The control group against which they were measured received compatible enrichment courses--minus the music. The Mozart-trained kids are now doing math three grade levels ahead of their peers, Shaw claims. Proof of all this, of course, is necessarily elusive because it can be difficult to do a double- blind experiment of educational techniques. In a double-blind trial of an arthritis drug, neither the study subjects nor the experts evaluating them know which ones got the test treatment and which a dummy pill. How do you keep the participants from knowing it's Mozart on the CD?

单选题 No Reservations? This Restaurant Trend Has Become Harder to Swallow. A. If you think the great equalizer in rank-conscious Washington is the Department of Motor Vehicles or a summons to appear for jury duty, you haven't been out to eat lately. Thanks to greed for fashionable food served in appetizer-size restaurants—and an abundance of millennial patience—the leveling agent for secretaries and Secretary of State alike boils down to this: More of us are waiting in line for dinner because restaurants aren't taking reservations. B. Eager to explore the Thai fireworks at Little Serow in Dupont Circle at prime time? Prepare to wait up to three hours on weekends for one of fewer than 30 seats. Meanwhile, ramen (拉面) lovers know it's easier to access Toki Underground on H Street NE on weekdays, when the wait might be a mere hour, versus the weekend, when the drill can take three times as long. C. The latest game-changer, Compass Rose off booming 14th Street NW, is a cozy source for international street food that offers snacks from Brazil, India and Spain—a little bit of everything, it seems, except for confirmed bookings. D. Restaurateurs say they don't take reservations because they want to avoid no-shows and latecomers, which eat into their bottom line, but also because they know they can pack in more diners. Indeed, the policy, which clearly favors host over guest, is creating tension and buzz; as different as the eateries (小饭馆) mentioned before are, they all play to full houses. It also illustrates an economy that has rebounded. In lean times, a business wouldn't dare make it difficult for you to use them. E. The reality that so many worthy young restaurants are forgoing (放弃) reservations is evidence of a culture that gets as excited to see a star chef as the FLOTUS, and of a city that's living to eat rather than eating to live. Food warriors now brag about scoring the dishes at Little Serow the way they used to boast about keeping a wine locker at Capital Grille. F. The shift is surprising for a city where power brokers like to be recognized and, better yet, to show off their standing. Maybe that's what sets Washington apart from other markets: a high degree of self-importance. No other major food city makes some of its most coveted seats so hard to secure. Challenging as they are to access, even white-hot Momofuku Noodle Bar in New York and Flour + Water in San Francisco offer some reservations. G. The allure of the near-unattainable has been good for other than the sexy restaurants in question; beneficiaries of the no-reservations policy include the hot spots' neighbors, where aspiring diners go to drink or snack while they wait, fingers crossed, to get a text or call informing them their table is ready. Jamie Leeds, the owner of two Hank's Oyster Bars near Little Serow and Rose's Luxury, picks up an extra dozen or so customers a night at her seafood eateries. The daily average might be small, she says, but over the course of the year, the numbers add up and the exposure is impressive. 'Customers come back on their own.' H. On the surface, not saving tables sounds egalitarian (平等主义的). Whoever shows up first has a shot at getting in, regardless of power or contacts. Anyone who has ever tried and failed to score seats at such extreme reservations as Minibar by José Andrés in Washington or the French Laundry from Thomas Keller in Napa Valley can appreciate the idea of more or less dining by lottery. I. But hospitality takes a holiday at establishments that don't book. In effect, these restaurants are saying, 'It's more important for us to fill every seat than to treat diners like guests.' Think about it. Who invites people to dinner and then makes them wait until the cook is good and ready to let you in, much less eat? By not guaranteeing tables, restaurants dismiss whole groups of would-be patrons. The masses include senior citizens who might not be able to stand for long or don't go out after dark, parents who may be reluctant to shell out $20 an hour for child care for a meal that may or may not happen, and suburban residents reluctant to drive in for the chance to be turned away. I smell ageism (对老年人的歧视). Sure enough, a scan of the dining rooms that don't book tables could be a casting call for a J.Crew catalogue. J. About that defense from restaurants, that the no-reservations policy helps them avoid no-shows? The hospitality industry would be wise to adopt the practice of doctors, dentists and fitness trainers, who charge customers who fail to show for an appointment. A fair penalty? The check average, per person, for every guest who fails to honor a commitment—Yelp blow-back be damned. Some restaurants publicly shame no-shows: Red Medicine in Los Angeles and Noma in Copenhagen have both posted the names of AWOL customers online. K. Affluent and over-educated Washingtonians are not used to being told no. It's one thing for Open Table to let you know, late at night in the comfort of your pajamas, you can't eat someplace on the day and time selected, quite another to be told 'no' in person at a host stand with dates, clients—anyone you want to impress—in tow. Such restaurant rejection is yet another reminder of disruption culture; the old rules and old access don't apply in 2014. L. Some argue that just because you like to eat doesn't give you entree anywhere. As a fashion designer with democratic impulses told me, 'You can't get XXL in Comme des Garcons.' Some experiences, in other words, will always be out of reach. M. If it hasn't happened yet, it will soon: Someone with more money than time is going to enlist the help of an assistant or receptionist to stand in line as a human place-holder for the bragging rights of a seat in a restaurant the public is dying to try. N. Fair or not—I vote not—that kind of behavior goes against the spirit of dining out, at least for me. A sense of friendship forms when you huddle with people on a joint mission, even one as transient as dinner, and for some participants, the excitement of landing a hot table ('Yes! We made it!') is right up there with successful deep-sea dives and climbs of Everest. O. Again, the restaurant wins, too. Which diner, having endured the difficulties of getting a reservation at Noma, perhaps the toughest ticket on the planet right now, is going to say the food was just okay? P. What goes around comes around. When Erik Bruner-Yang, the chef of the no-reservations Toki Underground, visited a like-minded peer, his verbal review of the production began: 'I waited two hours for Rose's.'
