The normal human daily cycle of activity is of some 7-8 hours’ sleep alternation(交替) with some 16-17 hours’ wakefulness and that the sleep normally coincides 【C1】______ the hours of darkness. Our present 【C2】______ is with how easily and to what extent this 【C3】______ can be modified.
The question is no 【C4】______ academic one.
The ease 【C5】______ which people can change from working !n the day to working at night is a 【C6】______ of growing importance in industry where automation(自动化) 【C7】______ round-the- clock working of machines. It normally 【C8】______ from five days to one week for a person to adapt to a 【C9】______ routine of sleep and wakefulness, sleeping during the day and working at night. 【C10】______ , it is often the case in industry that 【C11】______ are changed every week. This means that no sooner has he got used to one routine 【C12】______ he has to change to another, 【C13】______ much of his time is spent neither working nor sleeping very 【C14】______ .
One answer would seem to be 【C15】______ periods on each shift, a month, or even three months. 【C16】______ , recent research has shown that people on such systems will revert to go back to their 【C17】______ habits of sleep and wakefulness during the week-end and that this is quite enough to destroy any 【C18】______ to night work built up during the week.

选项
A、asks
B、invites
C、calls for
D、reacts to
答案
C
解析
考查语义。此处句意为: 自动化需要24小时工作。Call for意为“需要,要求”。Ask应用在ask sb.o do sth.构中:invite意为“邀请”,不符合句意;react to表示“对……作出反应”,不符合句意。
