单选题 With stripes of blue ink snaking across his face and neck and then disappearing under the collar of his shirt before bursting into the open from under the cuffs, he is a poster boy for his profession. Skitch, the only name he wants the public to know, exhibits pride and confidence in his designer skin. Comfortably perched atop a stool in Graffixx Tattoo, a parlor just two blocks from the White House, he talks about his obsession with" body art", which, in his view, is winning the souls of the New Age generation as well as overall public acceptance. "It's definitely more popular than when I started out about 10 years ago," he said as a flash of sunshine danced on a big pin piercing the skin between his eyes. "People who wouldn't even think about having a tattoo then have them. There are no official statistics beating Skitch out. But evidence that tattoos are growing more popular is abundant on beaches, in health clubs and on the streets when summertime clothes reveal roses, mermaids and increasingly more sophisticated ornaments on shoulders, ankles and other body parts. As far as Skitch is concerned, he is tiding the wave of the future. The revenue of a tattoo parlor he co-owned in Minneapolis, Minnesota between 1997 and 1999 grew 60 percent in its second year of operation, he said. "We would have made even more, if we operated in some southern resort towns, like Orlando; Daytona Beach or in southern California," he said. It is woman, he said, who is increasing numbers driving the body art boom. "If ten years ago only 40 percent of our clients requiring tattoos were women, now they make up 50 percent," notes Skitch. "For body piercing, it's 80 percent." Not so long ago, tattoo parlors were found in back rooms of seedy port city bars and catered to visiting sailors and city toughs. Not anymore. Next month, top female tattoo artists from North America and Europe will descend on Orlando, Florida, for a four-day convention, according to an announcement posted on the Internet by Deana Lippens, the organizer. Tattoos themselves have dramatically evolved over the years, becoming more complex, multi-dimensional, even exquisite, say tattoo artists. They are no longer just model rosettes hidden on a shoulder blade. Bodies are being transformed into full-scaled tableaux featuring, for example, portraits of saints adorned by garlands of flowers or a bald eagle spreading his wings across a human torso. Some of these tableaux take years to complete.

单选题When you first drift off into slumber, your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing will become quite regular. Your brain waves slow down a bit, with the alpha rhythm predominating for the first few minutes. This is the first stage of sleep. For the next 30 minutes or so, you will drift down through Stage 2 and Stage 3. The lower your stage of sleep, the slower your brain waves will be. About 40-60 minutes after you lose consciousness, you will reach the last stage. Your brain waves will show the delta rhythm. You may think that you stay at this deep stage all the rest of the night, but that turns out not to be the case. About 80 minutes after you fall into slumber, your activity cycle will increase slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids. This period of Rapid Eye Movements lasts for 8-15 minutes and is called REM sleep. During both light and deep sleep, the muscles in your body are relaxed but capable of movement. As you slip into REM sleep, a very odd thing occurs—most of the voluntary muscles in your body become paralyzed. Although your brain shows very rapid bursts of neural activity during REM sleep, your body is incapable of moving. REM sleep is accompanied by extensive muscular inhibition.

单选题 Many researchers have found greater dependence and obedience in very young girls, greater autonomy and activity in boys. When a barrier is set up to separate children from their mothers, boys try to knock it down; girls cry helplessly. There is little doubt that mother's encouragement or discouragement—of such behavior plays a major role in determining adult personality. For example, a mother often stimulates male autonomy by throwing a toy far away from her young son, thus silently suggesting to him that he leaves her to get it. Animal studies suggest that there may be a biological factor in material behavior; mothers of some monkeys punish their male babies earlier and more often than their female offspring; they also touch their female babies more often and act more protectively toward them. As for the controversial question of female "{{U}}passivity{{/U}}", psychologist Helen Deutsh believes that the concept has been misunderstood. "There is no contradiction between being feminine and working. The self can be active in both men and women," she says. It is only in love and sex that passivity is particularly appropriate for women. As she sees it, passivity is no more than a king of openness and warmth; it does not mean "inactivity of emptiness". Another controversy ranges over the effect of hormones. Aggressive women; who discount hormonal influence, disagree violently with scientific researchers, who almost unanimously agree that hormones help determine how people feel and act. So far, there have been few studies of male hormones, but scientists think they may eventually discover hormonal cycles in men that produce cyclic changes in mood and behavior. As for females, studies have indicated that 49 percent of female medical and surgical admissions, most psychiatric hospital admission and 62 percent of violent crimes among women prisoners are related with hormonal cycles in women.
