问题 Standby power is consumption of energy by electrical appliances even when they are plugged off.
If you want to save energy and keep maximum personal comfort in a winter room, you’d better choose to use ______.
选项
答案a small space heater
解析 由题干中in a winter room可定位到第三个小标题下第二段第二句A small space heater serves the same purpose in a room setting。[精析] 此处需要填入名词或名词性短语作use的宾语。根据上下文可知，该句中提到的same purpose即指节能和保持个人最大的舒适度，而该句中a small space heater即可满足题干中use的语义和语法需要。
