问题 As was estimated in 1997, .total telephone sets now in use in the United Stated numbered 170 millions. With so many sets______ into a system, efficiency is a major concern.
选项 A、compiled
B、knitted
C、integrated
D、elapsed
答案C
解析 题意是：如1997年所估计的那样，目前美国使用的电话机总数为1.7亿部。如此多的机子______一个系统，效率是主要担心的问题。[C] integrated“使并人”，integrate... into... “将…并入…”，符合题意。[A] compiled“编辑，收集”， [B] knitted“编，织”，[D] elapsed“消逝”都与题意不符。
