Perhaps the most important conclusion to be【C2】______from this evidence is【C3】______there is great variability among individuals in total sleep time. For adults,【C4】______between six and nine hours of sleep as a nightly average is not unusual, and 7.5 hours probably best expresses the norm. Such norms, of course, forms inevitably vary with the criteria of sleep employed. The most【C5】______and reliable figures on sleep time, including those cited here, come from studies in sleep laboratories, where EEG criteria are employed.
【C6】______consistently has been associated with the varying amount, quality, and pattern of electrophysiologically defined sleep. The newborn infant may spend an average of about 16 hours of each 24-hour period in sleep,【C7】______the sleep time drops sharply: by two years of age, it may【C8】______from nine to 12 hours. Decreases to approximately six hours have been observed among the elderly.
【C9】______will be discussed from below, EEG sleep studies have indicated that sleep can be considered to consist of several different stages. Developmental changes in the relative proportion of sleep time【C10】______in these sleep stages are as striking as age-related changes in total sleep time.
【C5】
选项
A、brief
B、precise
C、correct
D、concise
答案
B
