32. What does the author think of new devices?
- A. They are environment-friendly.
- B. They are no better than the old.
- C. They cost more to use at home.
- D. They go out of style quickly.
答案：A
答案句：We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That's bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
参考译文：我们可能认为自己是一个一看到闪亮新奇的东西就会扔掉旧技术的文化，但一项新研究表明，我们在旧设备过时很久后仍会继续使用它们。这对环境和我们的钱包来说都是坏消息，因为这些过时设备比做同样事情的新设备消耗更多能源。
定位线索：题干“What does the author think of new devices”→答案句取自第1段“these outdated devices consume much more energy than the newer ones”；文中“newer ones”对应选项“environment-friendly”（新设备更节能，即更环保）。
解析：题干问作者对新设备的看法。答案句明确指出旧设备比做同样事情的新设备消耗更多能源，暗示新设备更节能、更环保，因此A正确。B项“no better than the old”与原文相反；C项“cost more to use at home”偷换概念，原文说旧设备耗能多；D项“go out of style quickly”是作者否定的普遍想法，非作者观点。
33. Why did Babbitt's team conduct the research?
- A. To reduce the cost of minerals.
- B. To test the life cycle of a product.
- C. To update consumers on new technology.
- D. To find out electricity consumption of the devices.
答案：D
答案句：To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device.
参考译文：为了弄清楚这些设备使用了多少电力，纽约罗切斯特理工学院的Callie Babbitt和她的同事们追踪了每个产品在整个生命周期中的环境成本——从矿物开采到我们停止使用该设备。
定位线索：题干“Why did Babbitt's team conduct the research”→答案句取自第2段“To figure out how much power these devices are using”；文中“how much power”对应选项“electricity consumption”。
解析：题干问研究目的，答案句以“To figure out”直接给出目的，即弄清设备使用多少电力，与D项“find out electricity consumption”同义。A项“reduce the cost of minerals”无中生有；B项“test the life cycle”是研究方法而非目的；C项“update consumers”答非所问。
34. Which of the following uses the least energy?
- A. The box-set TV.
- B. The tablet.
- C. The LC
- D. TV. D. The desktop computer.
答案：B
答案句：They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
参考译文：他们发现，在平板电脑上而非电视和台式电脑上进行更多按需娱乐观看，可以将能源消耗削减44%。
定位线索：题干“Which of the following uses the least energy”→答案句取自末段“more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption”；文中“tablets”对应选项“The tablet”。
解析：题干问哪种设备耗能最少。答案句说明用平板替代电视和台式电脑可削减44%能耗，暗示平板耗能最低，因此B正确。A项box-set TV和D项desktop computer在原文中被列为高耗能设备；C项LCD TV虽未直接比较，但平板是替代方案，故排除。
35. What does the text suggest people do about old electronic devices?
- A. Stop using them.
- B. Take them apart.
- C. Upgrade them.
- D. Recycle them.
答案：A
答案句：So what's the solution(解决方案)? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
参考译文：那么解决方案是什么呢？团队的数据只到2007年，但研究人员还探索了如果消费者用具有多种功能的新电子产品（如用于文字处理和看电视的平板电脑）替换旧产品会发生什么。他们发现，在平板电脑上而非电视和台式电脑上进行更多按需娱乐观看，可以将能源消耗削减44%。
定位线索：题干“What does the text suggest people do about old electronic devices”→答案句取自末段“if consumers replaced old products with new electronics”；文中“replaced old products”对应选项“Stop using them”（停止使用旧设备）。
解析：题干问文章建议人们如何处理旧设备。末段提出解决方案是“replaced old products with new electronics”，即用新设备替换旧设备，隐含停止使用旧设备，因此A正确。B项“take them apart”、C项“upgrade them”、D项“recycle them”在原文中均未提及，属于无中生有。
