参考答案
正确答案:B
解析:由题干中的standby power和electrical appliances可定位到第一段第四句Standby power is the name given to the electricity used to power electrical appliances and devices even when they are turned off.[精析] 定义处设题。本题考查对standby power含义的理解。文中提到standby power电器件在关闭状态下(turn off)所耗的电能。而题干却将该词含义理解为电器在插头被拔掉(Plug off)后仍然耗电的状态。由于turn off和plug off含义不同,题干的含义与原文不符。
