单选题Potentially offering a powerful new tool against terrorism, researchers have found a novel way to detect deception: in the liar's blushing face. The technique, described in the journal, Nature, uses a thermal camera to detect sudden, involuntary shifts of blood flow in the face. The system performed as accurately as a traditional polygraph, the scientists report. Yet the camera can provide answers instantly, and does not require a highly trained specialist to operate it or interpret its results. This makes it far better suited than the polygraph for a new, high-tech approach to security that is already raising the hackles of civil libertarians: the screening of large numbers of citizens, at airports and other sensitive areas, who have done nothing wrong. "The next decade is going to see the development of truly accurate lie detectors, "said Stephen M. Kosslyn, an expert on detecting lies and a professor of psychology at Harvard University. The prototype, built by researchers at the Mayo Clinic and Honeywell Laboratories in Minnesota, is at least 2 years from being ready for general use. But other scientists said the discovery of previously unknown physiological changes in the face was itself an important step forward. "This is potentially very important work, which may open a new window on the mind, "said Kosslyn. Pushed by technological advances, and with fresh interest since Sept. 11, the discovery is part of a boom in the scientific study of deceit and its detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new approaches that might replace the polygraph, from brain scans, to subtle changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before. The new finding, though, is remarkable for its simplicity. When a person tells a lie, the team found, there is a sudden rush of blood to the area around the eyes, according to the Mayo Clinic's Dr. James A. Levine. Although the change is not ordinarily visible the blood warms the skin, causing bands of color to appear through a camera sensitive to heat. The team devised a computer program that can identify the telltale changes based on the camera images. In testing at the US Departmeot of Defense Polygraph Institute, which trains federal polygraph examiners, the device performed better than polygraphs, with 85 percent accuracy compared with 70 percent for the polygraph.

单选题It is inferred from the passage that

单选题 More than half of all Jews married in U.S. since 1990 have wed people who aren't Jewish. Nearly 480,000 American children under the age of ten have one Jewish and one non-Jewish parent. And, if a survey compiled by researchers at the University of California at Los Angeles is any indication, it's almost certain that most of these children will not identify themselves as "Jewish" when they get older. That survey asked college freshmen, who are usually around age 18, about their own and their parents' religious identities. Ninety-three percent of those with two Jewish parents said they thought of themselves as Jewish. But when the father wasn't Jewish, the number dropped to 38 percent, and when the mother wasn't Jew, just 15 percent of the students said they were Jewish, too. "I think what was surprising was just how low the Jewish identification was in these mixed marriage families." Linda Sax is a professor of education at UCLA. She directed the survey which was conducted over the course of more than a decade and wasn't actually about religious identity specifically. But Professor Sax says the answers to questions about religion were particularly striking, and deserve a more detailed study. She says it's obvious that interfaith marriage works against the development of Jewish identity among children, but says it's not clear at this point why that's the case. "This new study is necessary to get more in-depth about their feelings about their religion. That's something that the study that I completed was not able to do. We didn't have information on how they feel about their religion, whether they have any concern about their issues of identification, how comfortable they feel about their lifelong goals. I think the new study's going to cover some of that," she says. Jay Rubin is executive director of Hilel, a national organization that works with Jewish college students. Mr. Rubin says Judaism is more than a religion, it's an experience. And with that in mind, Hillel has commissioned a study of Jewish attitudes towards Judaism. Researchers will concentrate primarily on young adults, and those with two Jewish parents, and those with just one, those who see themselves as Jewish and those who do not. Jay Rubin says Hillel will then use this study to formulate a strategy for making Judaism more relevant to the next generation of American Jews.

单选题"Environmentally friendly" (Line 2, Para. 4) is closest in meaning to ______.

单选题Foreign propagandists have a strange misconception of our national character. They believe that we Americans must be hybrid, mongrel, undynamic; and we are called so by the enemies of democracy because, they say, so many races have been fused together in our national life. They believe we are disunited and defenseless because we argue with each other, because we engage in political campaigns, because we recognize the sacred right of the minority to disagree with the majority and to express that disagreement even loudly. It is the very mingling of races, dedicated to common ideals, which creates and recreates our vitality. In every representative American meeting there will be people with names like Jackson and Lincoln and Isaacs and Sehultz and Kovack and Sartori and Jones and Smith. These Americans with varied backgrounds are all immigrants or the descendants of immigrants. All of them are inheritors of the same stalwart tradition of unusual enterprise, of adventurousness, of courage--courage to "pull up stakes and git moving". That has been the great compelling force in our history. Our continent, our hemisphere, has been populated by people who wanted a life better than the life they had previously known. They were willing to undergo all conceivable hardships to achieve the better life. They were animated, just as we are animated today, by this compelling force. It is what makes us Americans.

单选题1 It was a normal day in the life of the American Red Cross in Greater New York. First, part of a building on West 140th Street, in Harlem, fell down. Beds tumbled through the air, people slid out of their apartments and onto the ground, three people died, and the Red Cross was there, helping shocked residents find temporary shelter, and food and clothing. Then it was back downtown for that evening's big fund-raiser, the Eleventh An nual Red Cross Award Dinner Dance, at the Pierre. "That's why I have bad hair to night," Said Christopher Peake, a Red Cross spokesman who had spent much of the day at the Harlem scene, in the drizzling rain. He was now in a tuxedo, and actually his hair didn't look so bad, framed by a centerpiece of tulips and jonquils, and perhaps improved by subdued lighting from eight crystal chandeliers. Definitely not having a bad-hair night was Elizabeth Dole, the wife of Senator Robert Dole and the president of the American Red Cross. President Dole has chestnut-colored Re publican hair, which was softly coifed, and she was wearing a fitted burgundy velvet eve ning suit ( "Someone made it for me! I love velvet!" she exclaimed, in her enthusiastic, Northern Carolina hostess voice) and sparkling drop earrings. Of course, she hadn't been standing in the rain in Harlem; she had just flown up on the three-o'clock shuttle from Washington. Dole is extremely pretty, with round green eyes and a full mouth and a direct personality. She tilts her head attentively when she listens. She was the recipient of the evening's award; previous award winners have included Alice Tully, Princess Yasmin Aga Khan and, most recently, Brooke Astor. Not exactly a sequence at the end of which you would expect to find Elizabeth Dole, but award givers are famous for having political instincts as well as philanthropic ones. Surrounded by the deep-blue swags and golden draperies of the ballroom were more than thirty-five dinner tables set with groupings of candles and floral centerpieces and Roy al Doulton china, American Express was there. So were Bristol-Myers Squibb; Coopers Lybrand; the New York Life; ...and Price Waterhouse. The actress Arlene Dahi, with her rather red hair and her bearded husband, presided over one table. Otherwise, it was a typical, faceless, captain-of-industry fund raiser (No models! No stars! ), of which there seems to be at least one every night in New York City. It was not a society night, but still the evening raised four hundred and thirty thousand dollars.
