14、rease : denounceAll mammals require sleep; it is an essential part of life. For giraffes, two hours aLine day is enough. For bats, that number is closer to twenty. The average adult humanneeds between seven and nine hours of sleep every day. Despite these differences,mammals all have one thing in co

15、mmon: If they do not get enough sleep, they can(5) suffer serious mental and physical consequences.The most extensive sleep research has been conducted on people. Throughthese studies, scientists have identified two broad categories of sleep, which canbe further divided into five stages with distinc

16、t physiological functions. Takentogether, they form a complete sleep cycle. The first four stages are marked by a(30) lack of rapid eye movement (REM). Therefore, they are referred to as non-REMsleep. While people are engaged in non-REM sleep, several things are occurring.Researchers have discovered

17、 that during this early sleep, the human bodyreleases a series of hormones responsible for the proper functioning of certainbody systems. Disrupted sleep can cause these hormones to fall out of balance.(15) The results can contribute to disorders such as diabetes, depression, infertility,or even can

18、cer. Lack of sleep, especially in stages 3 and 4, can literally stunt thegrowth of children and may increase rates of obesity in adults.Stage 5 sleep is defined by the occurrence of rapid eye movement, otherwiseknown as dreaming. Note that, while REM sleep is the final stage in a sleep cycle,(20) a

19、complete cycle generally lasts only about 95 minutes. A person will experiencefour to six cycles in one sleep session, with REM sleep taking up a larger portionof the cycle as the night continues. Scientists have advanced several theoriesabout why humans need REM sleep. One view is that dreaming aid

20、s in memoryconsolidation. Under this theory, during REM sleep the brain not only strengthens(25) memory of important actions or events, but it weakens memory of unimportantthings. Another view is that dreaming is necessary for proper central nervoussystem development. Yet another theory suggests tha

The theories are not necessarily exclusive; in fact,they all reach the conclusion that REM sleep deprivation can result in death.（分数：6.00）(1).The author of the passage is primarily concerned with（分数：1.00）A.(A) promoting mammalian sleep researchB
