問題詳情：

 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(裝置) 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 That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.

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. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.

So what's the solution（解決方案）? 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%.

【分析】

本文是一篇科普説明文。文章指出紐約羅徹斯特理工學院的Callie Babbitt和她的同事研究*實：舊電子設備要比新設備耗能高，所以作者主張使用新電子設備，既經濟又環保。

105．觀點態度題。根據文章第一段中的That’s bad news for the environment – and our wallets – as these outdated devices consume much more energy than the newer ones that do the same things.可知，使用舊的電子設備對環境和我們的錢包都是壞消息。這些過時的設備做相同的事情要消耗比新設備更多的能量。由此推知作者認為新電子設備環保、節能。故選A。

106．細節理解題。根據文章第二段中的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可知，Babbitt’s team研究的目的是弄清楚這些設備用了多少電。故選D。

107．細節理解題。根據文章最後一段中的They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.可知，平板電腦是耗能最少的電子設備，可以降低44%的耗能。故選B。

108．推理判斷題。根據文章的整體內容可知，因為舊的電子設備耗能高，不環保。所以作者建議停止使用舊的電子設備。故選A。

點睛：熟悉比較句型是徹底理解本文的關鍵，也是解題的關鍵。本文中的比較句型：

1. That’s bad news for the environment – and our wallets – as these outdated devices consume much more energy than the news ones that do the same things

做同樣的事，舊的過時的裝置比新裝置消耗更多能源，對環境有害，浪費錢財。

2. According to the analysis of Babbitt’s team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.

根據Babbitt團隊的分析，舊的桌面顯示器和*極*線管箱式電視機是最差的電子設備，它們的耗能和温室氣體的排放是1992到2007window的兩倍還多。

3. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.他們發現在平板電腦上看的隨需變化的*節目比在電視和電腦上看耗能減少了44%。
