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 （恒溫器） 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 （裝置） 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 （反饋） 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 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了谷歌新推出的智能裝置--Nest恒溫器，它不僅可以為主人節(jié)省費用，而且擁有許多智能化服務為顧客帶來了巨大的便利．
解答 32．D．推理判斷題．根據(jù)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有時外出時忘記調低恒溫器的溫度，以致取暖費用大增．不過，自從他買了谷歌的Nest恒溫器，他就不用擔心這個問題了．由此可推斷，Nest恒溫器幫助Andy Law節(jié)約了取暖費用．
33．B．推理判斷題．根據(jù)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恒溫器跨出智能裝置領域的第一步，由此可推斷，許多這類的智能裝置仍"在設計階段（on the drawing board）"．
34．D．推理判斷題．根據(jù)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，通過幾天的設置，Nest恒溫器能夠掌握主人平常對溫度的具體喜好．
35．A．推理判斷題．根據(jù)倒數(shù)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，每當使用者設定的溫度有助于節(jié)能，Nest恒溫器就會出現(xiàn)一片綠葉為使用者提供反饋．
點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
