单项选择题
In the early 20th century, at the advent of the telephone, it was considered a superfluous instrument which would never be of practical use in the average household.
A．appearance
B．popularity
C．dominance
D．consolidation
答案
参考答案：A
解析： 本题中，advent的意思是“出现，到来”。A项“appearance出现”符合题意，如：His sudden appearance surprised her.(他的突然到来使她很惊讶。)其他三项“popularity普及，流行；dominance优势，统治；consolidation巩固，合并”都不正确。
