泽熙美文Cloze Test
The normal human daily cycle of activity is of some 7-8 hours’ sleep 1 with some 16-17 hours’ wakefulness and that the sleep normally coincides 2 the hours of darkness. Our present 3 is with how easily and to what extent this 4 can be modified.
The question is no mere academic one. The ease with 5 people can change from working in the day to working at night is a 6 of growing importance in industry where automation 7 round—the-clock working of machines. It normally 8 from five days to one week for a person to adapt to a 9 routine of sleep and wakefulness, sleeping 10 the day and working at night. 11 it is often the case in industry that shifts are changed every week. This 12 that no sooner has he got used to one routine 13 he has to change to another, 14 much of his time is spent neither working nor sleeping very 15 .
One answer would seem to be 16 periods on each shift, a month, or even three months. 17 , recent research has shown that people on such systems will revert to go back to their 18 habits of sleep and wakefulness during the week-end and that this is quite enough to destroy any 19 to night work built up during the week. The only real solution appears to be to hand over the night shift to those permanent night workers whose 20 may persist through all weekends and holidays.
1.
A.allegation
B.alternation
C.allocation
D.alterative
正确答案：B
[解析] allegation意为“主张，断言”；allocation意为“分配，安置”，均与文章的意思不符。alternation意为“交替，轮换”，alternative是alternation的形容词形式，此处应填一个名词，所以B是正确答案。
2.
A.over
B.of
C.with
D.in
正确答案：C
[解析] 本题考查介词搭配。coincide with为固定词组，指“一致，相符合”，此处指“通常睡眠时间和白天时间相吻合”。而选项A，B，D不能与coincide搭配，故选C。
3.
A.think
B.consider
C.regard
D.concern
正确答案：D
[解析] 本题考查名词的辨析。句子的意思是我们目前所关心的是……，只有D选项Concern有“关心，关注”的意思，所以正确答案是D选项。
4.
A.round
B.circle
C.period
D.cycle
正确答案：D
[解析] 本题考查名词的辨析。cycle与前文保持一致，为“循环、周期”，此处指“我们现在关心在何等程度上，循环可以改善”。round意为“圆，圆形物”；circle意为“圆”；period意为“一段时间”，所以选项D为正确答案。
5.
A.for
B.that
C.which
D.as
正确答案：C
[解析] 本题考查“介词+关系代词”引导的定语从句的用法。关系代词在定语从句中作介词宾语时，从句常由“介词+关系代词”引导，如：The school in which he once studied is very famous. 此句的句子结构是：The ease(主语)+with…(介词+关系代词引导的定语从句)+is…，所以正确答案为C选项。
6.
A.matter
B.trouble
C.difficulty
D.problem
正确答案：A
[解析] 本题考查名词词义辨析。a matter of为固定词组，意为“(涉及的)问题”；trouble意为“麻烦”；difficulty指“困境”；problem指“难题，困难”，所以选A。
7.
A.reacts to
B.calls for
C.invites
D.asks
正确答案：B
[解析] 本题考查对动词词义的掌握。call for意为“需要，值得”，此处指“自动化需要机器昼夜不停地工作”。react to意为“反应”；invite意为“邀请”；ask意为“询问”，所以选B。
8.
A.requests
B.demands
C.spends
D.takes
正确答案：D
[解析] 本题考查对固定搭配的掌握。It takes some time to do sth.为固定句型；而选项A，B，C在句中不能以It作为形式主语，故选项D为正确答案。
9.
A.regular
B.reversed
C.returned
D.former
正确答案：B
[解析] 本题是形容词辨析题。reversed表示“反转的、颠倒的”；此处指“通常人们要花五天到一周的时间来适应一个相反的循环”。regular意为“有规律的”；returned意为“回的”；former意为“早期的”，所以正确答案是B选项。
10.
A.during
B.after
C.on
D.with
正确答案：A
[解析] 本题考查介词的用法。句子的意思是说在白天睡觉晚上工作，此处应该选择during，因为during the day表示在这一天的时间里，表示的是持续性的一天，所以选A。表示具体的星期、日、月应该用on，如：on that day, on Friday, on March，表示年用in，如：in 1999，但是如果年月日一起就用on，如：on the 1st，1999。
11.
A.In comparison
B.In a word
C.Unfortunately
D.Therefore
正确答案：C
[解析] 本题考查对上下文的理解。上文提到“颠倒作息时间大约需要五天到一个星期，而后文又说在工厂里这种轮班工作经常是每周一换的”。工人们刚调整过来的作息时间又得换回去，这显然是“不幸地”。in comparison意为“比较”；in a word意为“总之”；therefore意为“因此，所以”，意思上不符合原文，所以选C。
12.
A.mean
B.meaning
C.meant
D.means
正确答案：D
[解析] 本题考查谓语动词。此句的句子结构是This(主语)+谓语+that，主语是this，而且整篇文章用的都是一般现在时，所以这里就只能选则means，所以正确答案是D选项。
