问题 Standby power is consumption of energy by electrical appliances even when they are plugged off.
When we stay at a room in a house with central air-conditioning system in summer, we should set the thermostat to a higher level in ______.
选项
答案the rest of the house.
解析 由题干中central air-conditioning system可定位到第三个小标题下第三段第二句Dial up the thermostat in the rest of the house to keep the central air-conditioning system from running so often.[精析] 此处要求填入名词短语，与前面介词构成地点状语。题干中set...to a higher level与文中dial up意思相同，因此根据原文中的地点状语即可得出本题答案。
