问题 Standby power is consumption of energy by electrical appliances even when they are plugged off.
An adaptor can be used on cordless phones or answering machines to stop the consuming of standby power.
选项 A、Y
B、N
C、NG
答案C
解析 由题干中cordless phones or answering machines可定位到文中第四段。[精析] 段落事实细节处设题。本题考查有关无绳电话或留言机的耗电知识。该段首先说到无绳电话或留言机在准备状态要消耗大量电能，随后用具体数字说明了该类电器的耗能情况。文中并未提到如何改善这类电器以减少能耗。因此题干说的使用适配器以停止这类电器的准备状态下能耗，原文并未提及。
