问题     Current advances in home automation offer homeowners comfort, convenience, security and energy saving and a lot of impressive technology. With a fully automated home, you’d be able to pick up your phone, call your house and instruct it to disarm the security system, start the spa and turn up the lights. The interest in home automation is not born of a desire to create a space-age home, but to make a house safe, energy-efficient and more comfortable.
    Take security for example. If there is a fire, an automated house will detect it, turn off the gas, close the dampers in the ventilation system, turn on the lights, unlock the doors, set off an alarm and call the fire department. More advanced systems might even tell you where the fire is, and through which room you should escape.
    With Home Manager, one of several automation systems on the market, you can warm up the master bedroom, kitchen and bathroom in the morning before alarm goes off. Or you can program it to keep the nursery at a constant temperature. In midsummer, you can even instruct sensors in the house to open skylights, turn on ceiling fans, and close the draperies when the house reaches a certain temperature. All of these functions can be controlled while in the house or remotely from a phone or computer.
    In addition, home automation offers tremendous lifestyle improvements for elderly and disabled people. For those who cannot push a button or flip a switch, a voice command can be used to activate security cameras, turn up the stereo volume or drop the room temperature a few degrees. The click of an infrared remote control could turn on the oven, close the blinds or open the door.
According to the passage, home automation can offer the following benefits EXCEPT________.
选项 A、safety
B、cleanliness
C、convenience
D、energy-efficiency
答案B
解析 细节理解题。根据文章第一段第一句“Current advances in home automation offer homeowners comfort, convenience, security and energy saving and a lot of impressive technology. ”可知，家庭自动化可以提供舒适、方便、安全和节能等的好处。故选B。
