In this factory the machines are not regulated ______ but are jointly controlled by a central computer system.
A．independently
B．individually
C．irrespectively
D．irregularly
-
正确答案：B
解析：本题为副词词义辨析题。individually意为"逐个地、单独地"；independently意为"独立、自主地"；irregularly意为"不规则，不整齐地"；irrespectively意为"不论，不顾"。individually可与句中 jointly形成对照，以说明工厂的机器不是"单独"操作而是由计算机"统一"控制。
