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 That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.

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. \replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house,\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? The team's data only went up to 2007, but the researchers also explored what （解决方案）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%. 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.

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. 34. Which of the following uses the least energy? A. The box-set TV. C. The LCD TV.

B. The tablet.

D. The desktop computer.

35. What does the text suggest people do about old electronic devices? A. Stop using them. C. Upgrade them.

B. Take them apart. D. Recycle them.

【答案】32. A 33. D 34. B 35. A

33. 细节理解题。根据文章第二段中的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这些设备用了多少电。故选D。 34. 细节理解题。根据文章最后一段中的They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.可知，平板电脑是耗能最少的电子设备，可以降低44%的耗能。故选B。

35. 推理判断题。根据文章的整体内容可知，因为旧的电子设备耗能高，不环保。所以作者建议停止使用旧的电子设备。故选A。

点睛：熟悉比较句型是彻底理解本文的关键，也是解题的关键。本文中的比较句型：

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 做同样的事，旧的过时的装置比新装置消耗更多能源，对环境有害，浪费钱财。

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. 根据Babbitt团队的分析，旧的桌面监视器和阴极射线管箱式电视机是最差的电子设备，它们的耗能和温室气体的排放是1992到2007window的两倍还多。

3. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.他们发现在平板电脑上看的随需变化的娱乐节目比在电视和电脑上看耗能减少了44%。

Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia’s fields are little powerhouses of nutritional protection.

Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.

When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.zx.x.k

If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert, to be eaten right away. This makes a fun activity for a children’s party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below. 24. What does the author seem to like about cherries?

A. They contain protein. B. They are high in vitamin A. C. They have a pleasant taste. D. They are rich in antioxidants.
