问题 Standby power is consumption of energy by electrical appliances even when they are plugged off.
To save energy, we’d better turn the humidistat to a level that ______.
选项
答案we call live with
解析 由题干中save energy和level可定位到第二个小标题下第四段最后一句Finding a humidity level you can live with--and then setting the humidistat to that level--will result in the unit running intermittently， which saves energy compared to one that runs continuously.[精析] 此处需填入从句。根据原文可知，将湿度设定器设定到你能够容忍的湿度可以使除湿器间断性地工作，以达节能的效果。文中humidistat之后的that level与破折号前humidity level所指对象相同，因此修饰humidity level的定语从句即为答案。
