The modern age is an age of electricity. People are so used to electric lights, radio, televisions, and telephones that it is hard to【S1】______what life would be like without them. When there is a【S2】______failure, people grope about in candlelight, cars【S3】______in the streets because there are no traffic lights to guide them, and food【S4】______in silent refrigerators.
Yet, people began to understand how electricity works only a little more than two centuries ago. Nature has【S5】______been experimenting in this field for million of years. Scientists are【S6】______more and more that the living world may hold many interesting secrets of electricity that could benefit humanity.
All living cells send out tiny pulses of electricity. As the heart【S7】______, it sends out pulses of record; they form an electrocardiogram(心电图), which a doctor can study to determine how well the heart is working. The brain, too, sends out brain【S8】______of electricity, which can be recorded in an electroencephalogram(脑电图). The electric currents generated by most living cells are extremely small--often so small that【S9】______instruments are needed to record them. But in some animals, certain muscle cells have become so specialized as electrical generators that they do not work as muscle cells at all. When large numbers of these cells are linked together, the effects can be【S10】______.
A)spoils I)apparently
B)sensitive J)discovering
C)beats K)reasonable
D)waves L)power
E)astonishing M)hits
F)seemingly N)imagine
G)stop O)hesitate
H)determine
【S2】
选项
答案
L
解析
因为failure是名词,所以该空应填一个形容词或名词来修饰failure。由people grope about in candlelight可知,因为没有电,人们才点燃蜡烛。power failure意思为“停电”。
