问题 What is said to be the best way to conserve energy nowadays?
Global residential power consumption can be cut by 43 percent if ______.
选项 A、we increase the insulation of walls and water pipes
B、we choose simpler models of electrical appliances
C、we cut down on the use of refrigerators and other white goods
D、we choose the most efficient models of refrigerators and other white goods
答案D
解析 本题问“全球居民用电量可以通过什么方式减少百分之四十三?”根据题文中“43 percent”可将相关部分定位于小标题为“A Better Fridge(更好的冰箱)”部分。全文第十二自然段最后一句话提到“... if consumers choose those models that would save them the most money over the life of the appliance，they’d cut global residential power consumption by 43 percent.”，即“……如果消费者选用最节省能源的电器型号，则可以减少全球居民用电的百分之四十三。”因此，D项“选择高效节能的冰箱和其他电器”正确。A项“增加墙壁和墙纸的隔热设施”、B项“选择更简单的电器型号”、C项“减少冰箱和其他电器的使用”文中均未提及。
