简答题 According to an International Energy Agency study, if consumers chose those models that would save them the most money over the life of the appliance, they’d cut global residential power consumption (and their utility bills) by 43 percent.

解析

【分析】本句为复合句。主句为“they’d cut… by 43 percent”。 if 引导条件状语从句,在从句中包含了一个that引导的定语从句,修饰models. 这个条件状语从句为虚拟语气,表示对现在的假设,从句谓语用过去时态,主句谓语动词用would do.
