问题                     Turning Vivid Dreams Into Reality
    Researchers at Stanford University are now developing software to help people become aware that they are having a dream so that they can then live out their fantasies during Rapid Eye Movement (REM) sleep. During lucid dreams, people are "awake" within their dreams, and can sometimes direct what happens next in the dream. With enough practice you can fly, visit exotic places, experience vivid colors, or eat all the ice cream you want, all without taking your head off the pillow.
    Being awake during a dream may seem like a contradiction, but to those involved in lucid dream research, it’s all, well, crystal clear. "Lucid dreaming lets you make use of the dream state that comes to you every night to have a stimulating reality," said Dr. Stephen LaBerge, founder of the Lucidity Institute at Stanford University. LaBerge said that controlling dreams can also have therapeutic value. Potentially, he said, people can overcome nightmares that attack them repeatedly. It may even help a person improve in sports, enhance self-confidence or confront problems that avoid being solved in waking life. Exploring the World of Lucid Dreaming, a book co-authored by LaBerge and Howard Rheingold, is one of many books to help would-be lucid dreamers get started. The book asks that you learn to recognize "dreamsigns," or signals within a dream that alert you to your altered state. One common dreamsign: elements within your dream are out of context. Objects are not where they belong within a room, or certain people are in locations they normally wouldn’t be—how often do your parents drop in at the office? The Lucidity Institute’s NovaDreamer includes a mask that tracks eye movement to recognize when you’re in REM as well as to determine the amount of time you take to get to sleep. Depending on how you set Nova-Dreamer (a determination made partially on the basis of how light or heavy a sleeper you are), the NovaDreamer flashes a series of red lights into your (hopefully closed) eyes, providing yet another signal that you are dreaming and can now do whatever you please in the dream.
    LaBerge’s research indicates that when a person does something in their dreams, the experience may be closer to reality than you’d think. Early experiments show that lucid dreamers have a good comprehension of time while dreaming. Researchers that asked lucid dreamers to move their eyes in a specific pattern, and then repeat the pattern 10 seconds later, found they did so in about the correct amount of time. LaBerge said dreaming of doing something causes the same reaction in your brain waves as actually doing it. During REM sleep, says LaBerge, "the brain is working full-tilt, yet it is disconnected from the outside world. If you dream of doing a long jump, your brain reacts the same way it would if you actually did it." [br] According to the passage, the NovaDreamer is______.
选项 A、a timer to measure the time it takes to fall asleep
B、a machine to induce lucid dreams
C、an electronic book about lucid dreams
D、a software of monitoring lucid dreams
答案 B
解析 本题考查事实细节。有关“新梦人”的介绍出现在第四段。从该段对其功能的论述可知，它应是一个机器。该段提到，“新梦人”可以通过信号提醒睡梦者他正在做梦，使他可以在梦中做任何想做的事情了。因此该机器的功能是“引起清晰梦境”。[B]项正确。
