Throughout history man has observed such natural cycles as the rising and setting of the sun, the ebb and flow of the ocean tides, and the changes of the seasons. The【C1】______ nature of these events provided people with a measure of【C2】______ about things to come and give them reason to reflect on their past and plan for their future. The regularity of such social activities as work hours, meal times, and holiday schedules【C3】______ the extent to which human activity itself is organized in cycles.
Recently,【C4】______ effort has been spent investigating the effect of various biological rhythms in the human body.【C5】______ , interest in these rhythms at least in part results from man’s basic desire to predict future behavior.

Scientists studying rhythms in humans have measured sleep patterns and attention【C7】______ over periods of several days, and have【C8】______ the fact that the cycles exist and exert effects on physiological and sociological behavior. A common example is jet lag. A person’s traveling in the east-west direction across time zones【C9】______ his sleep cycles—it may take several days to return to the【C10】______ cycle or to readjust to a new one.
A) indicates E) considerable I) Certainly M) security
B) demonstrated F) upsets J) Thankfully N) exhibits
C) verifying 6) disappoints K) spans O) limits
D) normal H) periodic L) gorgeous
【C4】
选项
答案
E
解析
此处填入修饰effort的词,可能是名词、形容词或分词。这里讲的是人们研究人体生理节律所做的努力。considerable“大量的”带入句中意思最通顺,故为答案。normal指“正常的”,语义上不如considerable准确。
