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．"

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了谷歌新推出的智能装置--Nest恒温器，它不仅可以为主人节省费用，而且拥有许多智能化服务为顾客带来了巨大的便利．
解答 32．D．推理判断题．根据第一段中的He'd sometimes forget to turn down the thermostat 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可知，Andy Law有时外出时忘记调低恒温器的温度，以致取暖费用大增．不过，自从他买了谷歌的Nest恒温器，他就不用担心这个问题了．由此可推断，Nest恒温器帮助Andy Law节约了取暖费用．
33．B．推理判断题．根据第二段中的so the Nest thermostat first provides a good example of what is fast coming down the road可知，谷歌的Nest恒温器跨出智能装置领域的第一步，由此可推断，许多这类的智能装置仍"在设计阶段（on the drawing board）"．
34．D．推理判断题．根据第三段中的the Nest thermostat can understand what its owners want以及After four days，Nest learns enough to keep the house as hot or cold as the person generally prefers at different times可知，通过几天的设置，Nest恒温器能够掌握主人平常对温度的具体喜好．
35．A．推理判断题．根据倒数第二段中的"Nest Leaf，"which gives the user feedback whenever the temperatures they set save energy…a green leaf appears on the thermostat可知，每当使用者设定的温度有助于节能，Nest恒温器就会出现一片绿叶为使用者提供反馈．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
