When a person falls asleep, all activity decreases and the muscles relax. The heartbeat and breathing【C1】______slow down. The person slowly becomes less aware【C2】______what may be happening all around. A sleeping person changes the【C3】______of the entire body at least a dozen times during about eight hours of sleep. The head, arms, or legs are moved more often.
Scientists study sleep【C4】______an instrument. Whether a person is【C5】______or asleep, the brain gives【C6】______electrical waves. The instrument measures and records these waves. The brain of an awake, 【C7】______person gives off about 10 small waves a second. As a person falls deeply【C8】______sleep, the brain sends out slower but 【C9】______waves. The slowest, largest waves【C10】______during the first two or three hours of a period of sleep. During slow-wave sleep, mental activity【C11】______down but does not stop. Persons awakened【C12】______slow-wave sleep can often【C13】______unclear thoughts that they had while asleep. Periods of small, fast waves, 【C14】______to those of an awake person, occur at【C15】______during sleep. During these periods of fast brain wave activity, the sleeper’s eyes move rapidly as though they were watching the【C16】______of a dream. A sleeper who is awakened during such a period probably will recall dreaming and remember【C17】______of the dream. Sleep during these periods is called dreaming sleep or REM (Rapid Eye Movement) sleep. An eight-hour period of sleep includes from three to five periods of dreaming sleep. The dreaming sleep periods【C18】______from 5 to 30 minutes【C19】______and occur every 90 to 100 minutes. The【C20】______dream periods last longer than the earlier ones. [br] 【C6】
选项
A、in
B、off
C、to
D、away
答案
B
解析
语义衔接题。[A]、[B]和[D]均可以与空前的give搭配:give in意为“屈服”,give off意为“发出”,give away意为“送掉,分发”。根据上下文可知,此处说的是大脑发出电波,故答案为[B]off。第73题空后的off为所填词的原词复现,对选择答案有很强的提示作用。
