F. problem G. longer H. cycle I. matter J. illustrates
K. hand over L. formal M. reversed N. habit O. means
The normal human daily cycle of activity is some 7-8 hours’ sleep alternation with some 16-17 hours’ wakefulness and that the sleep normally coincides with the hours of darkness. Our present concern is how easily and to what extent this【C1】______ can be modified.
The question is not merely an academic one. The ease with which people can change from working in the day to working at night is a【C2】______ of growing importance in industry where automation【C3】______round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a【C4】______ routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts are changed every week. This【C5】______ that no sooner has he got used to one routine than he has to change to another,【C6】______ much of his time is spent neither working nor sleeping very efficiently.
One answer would seem to be【C7】______ periods on each shift, a month, or even three months. However, recent research has shown that people on such systems will go back to their 【C8】______ habits of sleep and wakefulness during the weekend and that this is quite enough to destroy any adaptation to night work built up during the week. The only real solution appears to be to【C9】______ the night shift to those permanent night workers whose【C10】______ may persist through all weekends and holidays.
【C8】
选项
答案
C
解析
空格前为物主代词their,而空格后为名词habits,故空格处应填入修饰habits的形容词。由go back(恢复到)可推断,恢复到的应是正常的睡眠和清醒习惯,因此选词库中的normal“正常的”。
