Sleep Lets Brain File Memories1
To sleep. Perchance to file?2 Findings published online this week by the Proceedings3 of the National Academy of Sciences further support the theory that the brain organizes and stows memories formed during the day while the rest of the body is catching zzz"s4.
Gyorgy Buzsaki of Rutgers University5 and his colleagues analyzed the brain waves of sleeping rats and mice. Specifically, they examined the electrical activity emanating from6 the somatosensory neocortex7 (an area that processes sensory information) and the hippocampus8, which is a center for learning and memory. The scientists found that oscillations in brain waves from the two regions appear to be intertwined. So-called sleep spindles (bursts of activity from the neocortex) were followed tens of milliseconds9 later by beats in the hippocampus known as ripples. The team posits that this interplay between the two brain regions is a key step in memory consolidation. A second study, also published online this week by the Proceedings of the National Academy of Sciences, links age-associated memory decline10 to high glucose levels.
Previous research had shown that individuals with diabetes suffer from increased memory problems. In the new work, Antonio Convit of New York University School of Medicine and his collaborators studied 30 people whose average age was 69 to investigate whether sugar levels, which tend to increase with age, affect memory in healthy people as well. The scientists administered11 recall tests, brain scans and glucose tolerance tests, which measure how quickly sugar is absorbed from the blood by the body"s tissues. Subjects with the poorest memory recollection, the team discovered, also displayed the poorest glucose tolerance. In addition, their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb blood sugar.
"Our study suggests that this impairment12 may contribute to the memory deficits13 that occur as people age." Convit says. "And it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition.14" Exercise and weight control can help keep glucose levels in check15, so there may be one more reason to go to the gym.

Which of the following does NOT indicate people's enhanced awareness of the importance of memory?
A:More demand for books on memory. B:More demand for seminars on memory. C:More demand for memory-enhancing supplements. D:More demand for coca cola and cigarettes.
The purpose of （66） is to enlarge the （67） , the set of addresses a program can utilize. For example, it might contain twice as many addresses as main memory. A program using all of it, therefore, would not be able to fit in main memory all at once. Nevertheless, the computer could execute such a program by Copying into main memory those portions of the program needed at any given point during execution.
To facilitate copying （67） into real memory, the operating system divides it into pages, each of which contains a fixed number of addresses. Each page is stored on a disk until ii is needed. When the page is needed, the operating system copies it from disk to main memory, translating the （68） into real addresses. The process of translating virtual addresses into real addresses is called （69） . The copying of virtual pages from disk to main memory is known as （70） or swapping.
A:fake memory B:false memory C:virtual memory D:mendacious memory
