3．During the winter Andy Law likes tokeep his house warm，which used to be a problem．He'd sometimes forget to turn down the thermostat （恒温器） when he traveled，which raised his heating bills．But he hasn't had to worry about that since buying one of Google's Nest thermostats．
In fact，companies are developing many smart devices （装置） that will tailor their functions to what they learn about their users'needs．But many of these devices are still on the drawing board，so the Nest thermostat first provides a good example of what is fast coming down the road．
Officials at Google Inc．say the Nest thermostat can understand what its owners want．"The first three to four days is when it's most eager to learn，"said Maxime Veron，director of product marketing for Nest．"It gathers data，temperature，the time it was set and occupancy．"After four days，Nest learns enough to keep the house as hot or cold as the person generally prefers at different times．
One feature that will click in about a week after Nest starts learnng is its"Auto-Away"function．Nest will automatically adjust the temperature to whatever the person previously has indicated they prefer when they're gone．
The Auto-Away sensors also are designed to scan a room for movement"above most pets'heads，"so it doesn't mistake a dog or cat for a person and assume someone is still in the home．But the thermostats can be fooled by large pets．
Another feature many people seem to like is"Nest Leaf，"which gives the user feedback （反馈） whenever the temperatures they set save energy．So if the person raises the temperature enough on a hot day or down on a cool one，a green leaf appears on the thermostat．
However，some people say that it is too expensive．But after trying it out，PC Magazine editor John Delaney said，"It is a must for anyone looking to save on heating and air conditioning costs and I like the idea of setting it and forgetting it．"
