单选题Is technology changing our brains? A new study adds to a growing body of research that says it is. According to the study, a 27 shift in how we gather information and communicate with one another has touched off an era of rapid evolution that may 28 change the human brain as we know it. The impact of technology on our brain should not come as a 29 . Professional musicians have more gray matter in brain regions 30 for planning finger movements. And athletes' brains are bulkier in areas that 31 hand-eye coordination. That's because the more time you devote to a specific activity, the stronger the neural (神经系统的) pathways responsible for executing that activity become. So it makes 32 that people who process a constant stream of digital information would have more neurons dedicated to filtering (过滤) that information. To see how the Internet might be rewiring us, the brains of 24 adults were 33 as they performed a simulated Web search, and again as they read a page of text. During the Web search, those who reported using the Internet 34 in their everyday lives showed twice as much signaling in brain regions responsible for decision-making and complex reasoning, compared with those who had 35 Internet exposure. The findings suggest that Internet use enhances the brain's 36 to be stimulated, and that Internet reading activates more brain regions than printed words.

单选题 Most of us tend to think that attractive people are always at an advantage in life and enjoy far more opportunities than average-looking or unattractive people, especially when it comes to employment. But a new study suggests this perception is actually not the case for all jobs. Beautiful people are less likely to land menial jobs or positions that involve uninteresting work. The study published Tuesday in the Journal of Personality and Social Psychology finds being beautiful is a liability when it comes to seeking out less desirable positions, which is proof that attractive people don't get everything they want. The researchers found people interviewing and hiring for these jobs favor unattractive candidates because they perceived attractive candidates would be dissatisfied with the pay and the work. The findings are based on a series of experiments that involved more than 750 people. They included university students and hiring managers. The researchers showed the hiring managers profiles that included photos of potential candidates (one attractive and one not so much). The researchers asked the hiring managers a series of questions that were meant to assess their perceived attractiveness. They also asked the participants which candidate they were more likely to hire for the low-paying positions that included warehouse worker, customer service representative and housekeeper versus more appealing jobs such as manager, project director and an IT internship (实习生). The researchers found that the hiring managers' decisions were driven by their belief that the nice-looking candidates would be unhappy and unsatisfied with the menial jobs and maybe even less likely to do the work. The researchers were surprised by this, since previous research has shown that attractive people always have an edge with employment, such as a study in which researchers sent 1100 fake resumes to employers to fill advertised vacancies. They found 54 percent of attractive women were contacted while 47 percent of attractive men received calls, according to the Independent. On the other hand, only 7 percent of unattractive women and 26 percent of unattractive men were contacted by potential employers. The authors of the new study suggest their findings should be considered when it comes to creating policies about job discrimination. This conclusion is likely to be laughable to unattractive people who have landed jobs but didn't win the genetic lottery.

单选题The Supreme Court's decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering. Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of "double effect," a centuries-old moral principle holding that an action having two effects--a good one that is intended and a harmful one that is foreseen--is permissible if the actor intends only the good effect. Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients' pain, even though increasing dosages will eventually kill the patient. Nancy Dubler, director of Montefiore Medical Center, contends that the principle will shield doctors who "until now have very, very strongly insisted that they could not give patients sufficient medication to control their pain if that might hasten death." George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. "It's like surgery," he says. "We don't call those deaths homicides because the doctors didn't intend to kill their patients, although they risked their death. If you're a physician, you can risk your patient's suicide as long as you don't intend their suicide." On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying. Just three weeks before the Court's ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the undertreatment of pain and the aggressive use of "ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care. The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a Medicare billing code for hospital-based care, and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care. "Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering," to the extent that it constitutes "systematic patient abuse." He says medical licensing boards "must make it clear...that painful deaths are presumptively ones that are incompetently managed and should result in license suspension./
