问题
Standby power is consumption of energy by electrical appliances even when they are plugged off. [br] 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。
