The business practices of America will have you in the office from nine in the morning to five in the evening, if not longer. Much of the world, though, prefers to take a nap. And research presented to the AAAS (American Academy of Arts and Sciences) meeting in San Diego suggests it may be right to do so. Matthew Walker and his colleagues at the University of California, Berkeley, have found that they probably have better memory, too. A post-meal snooze, Dr Walker has discovered, sets the brain up for learning.
The role of sleep in consolidating memories that have already been created has been understood for some time. Dr Walker has been trying to extend this understanding by looking at sleep’s role in preparing the brain for the formation of memories in the first place. He was particularly interested in a type of memory called episodic memory, which relates to specific events, places and times. This contrasts with procedural memory, of the skills required to perform some sort of mechanical task, such as driving. The theory he and his team wanted to test was that the ability to form new episodic memories deteriorates with increasing wakefulness, and that sleep thus restores the brain’s capacity for efficient learning.
They asked a group of 39 people to take part in two learning sessions, one at noon and one at 6pm. On each occasion the participants tried to memorize and recall 100 combinations of pictures and names. After the first session they were assigned randomly to either a control group, which remained awake, or a nap group, which had 100 minutes of monitored sleep. Those who remained awake throughout the day became worse at learning. Those who napped, by contrast, actually improved their capacity to learn, doing better in the evening than they had at noon. These findings suggest that sleep is clearing the brain’s short-term memory and making way for new information.
The benefits to memory of a nap, says Dr Walker, are so great that they can equal an entire night’s sleep. He warns, however, that napping must not be done too late in the day or it will interfere with night-time sleep. Moreover, not everyone awakens refreshed from a nap. The dazedness that results from an unrefreshing nap is termed "sleep inertia". Sara Mednick, from the University of California, San Diego, suggests that non-habitual nappers suffer from this more often than those who snooze regularly. It may be that those who have a tendency to wake up dazed are choosing not to nap in the first place. Perhaps, though, as in so many things,
it is practice that makes perfect
.
Dr. Walker would most probably agree that ________.
选项
A、a nap can replace an entire night’s sleep
B、non-habitual nappers will suffer from "sleep inertia"
C、people should not nap too late in the day
D、people who wake up dazed should not choose to nap
答案
C
解析
本题实际上问的是沃克博士的观点,根据题干可定位到第四段(因为第四段第一句说…says Dr Walker…“沃克博士称……”,可见该段就有沃克博士的观点)。该段第二句说,沃克博士警告白天小睡的时间不能太晚(must not be done too late in the day),否则就会干扰晚上的睡眠。C项与原文吻合。第四段第一句说,沃克博士称,小睡对记忆的益处如此之大,甚至equal“抵得上”整晚的睡眠,但这并不代表小睡可以replace“取代”整晚的睡眠,所以A项属于过度推断。根据第五句,非习惯性午睡者比经常午睡的人更容易睡后迟钝,但并不是一定会睡后迟钝,B项过于绝对。根据第六句,也许是因为醒来有眩晕倾向的人一开始就选择了不午睡,It may be that…“也许……”表明了这是一种猜测,而不是沃克博士认为这些人不应该选择午睡。D项错误。
