题目解答
答案
句意：由于它扎根于手机行业，人们预计蓝牙手机将扩大市场，创建数百万个“无线中心”，这个“无线中心”将承载一系列连接设备。
考查词义辨析。A. grade 分级; 分等 B. flood 灌满水; 淹没 C. retreat 退却; 撤退; 离开 D. expand 扩大; 增加；扩展
根据句意可知，expand “扩大; 增加；扩展”符合。故选D项。
解析
本题考查词义辨析能力，需要根据上下文语境选择最合适的动词。解题核心在于理解句子中"Bluetooth phones"对市场的影响。句中提到"创建数百万个'无线中心'"，暗示市场范围的扩大，因此需选择与扩展、增长相关的词汇。
选项分析
A. grade
意为“分级、分等”，与市场扩展无关，排除。
B. flood
虽然有“大量涌入”的含义，但更强调“淹没”或“泛滥”，与句中“创建无线中心”的正面扩展意义不符。
C. retreat
意为“退却、撤退”，表示市场缩小，与句意相反。
D. expand
“扩大、扩展”直接对应“创建更多无线中心”的动作，符合语境。
