Thats bad news for the environment and our

2、wallets as these outdated devices consume much more energy than the newer ones that do the same things.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 throug

3、hout 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

4、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 didnt throw out our old ones. The living- room television is replaced and gets planted in the kids room, and suddenly on

5、e 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. Were not just keeping these old devices we continue to use them. According to the analysis of Babbitts team, old desktop monitors and box

6、 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 whats the solution（解决方案）? The teams data only went up to 2007, but the researchers also explored what would happen if

7、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%. 33. Why did Babbitts

8、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?(转换理解题) A. The box-set TV. B. The tablet. C. The LCD

9、 TV. D. The desktop computer.

Truck driver Colm,35, suffered a mystery allergic reaction on Saturday and was taken to hospital, but was sent home only for it to happen again the next day. The second attack was so serious that his airway swelled, p

15、reventing him from breathing, his blood pressure dropped suddenly, and his heart stopped for a moment. He has now made a full recovery from his suffering. Whats the right order of the events? Izzy kicked Colm. Debbie called 999. Izzy learned CPR. Colms heart stopped. A. B. C. D. C 【解析】 结合第六段第一句 My m

16、um taught me CPR，倒数第二段 最后一句 his heart stopped for a moment，第二段 Izzy, nine, restarted father Colms heart by stamping(踩) on his chest after he fell down at home and stopped breathing 和第二段 Debbie, immediately called 999，可知顺序为3、4、2、1。 故正确答 案为C。 【点拨】 此类题目要求考生根据动作发生的时间顺序及句子之间的 逻辑关系，找出事件发生、发展的正确顺序。可采用首尾定 位

17、，即，先找出第一件事情和最后一件事情，迅速缩小范围， 快速选出正确答案。 【典例二】图文转换题 在有图表图画的阅读理解中， 有的图表图画出现在阅读理解文章中，有的出现在选 项中，这些图片的出现增加了试题的直观性，同时也 暗含着和文章内容相关的信息。在解答此类试题的时 候，一定要把握图表图画中所暗含的信息，特别是有 些事实是通过图片来叙述的，我们可以采用按图寻找 正确答案的方法。 71.

18、 35 points B. the percentage of the White families with a computer remained unchanged C. the number of the Black families with a computer was on the decrease D. the number of the Asian families with a computer showed the sharpest increase 【解析】D。请看原文中的柱形图： 由柱形图可以清楚地看出，拥有电脑的亚洲家庭的数 量急剧增加，其他三项表述都与图表不符，故

19、D项正确。 D 【典例三】数字转换题 (2018 全国卷阅读C)At present, the world has about 6,800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages, often spoken by many people, while hot, wet zones have lots, often spoken by small numbers. Europe

20、 has only around 200 languages; the Americas about 1,000; Africa 2,400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number (中位数) of speakers is a mere 6,000, which means that half the worlds languages are spoken by fewer people than

21、that. How many languages are spoken by less than 6,000 people at present? AAbout 6,800. BAbout 3,400. CAbout 2,400. DAbout 1,200. B 根据信息句“The median number (中位数) of speakers is a mere 6,000，which means that half the worlds languages are spoken by fewer people than that.”可知，目前全球不同语言使 用人数的中位数仅是6,000，这

22、就意味着世界上有一半的语言的 使用人数不到6,000；结合“At present，the world has about 6,800 languages.”可知正确选项为 B。 【典例四】同义（反义）转换题 (2020 全国卷阅读D )Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they

44、ng uses the least energy? A. The box-set TV. B. The tablet. C. The LCD TV. D. The desktop computer. D B 【解析】 3.根据第二段第一句中的“To figure out how much power these devices are using.”以及后面的介绍可知， Babbitt 的团队进行这项研究的目的是弄清楚这些设备 的耗电情况。故答案为D 4. 由于设备越新越省电，在根据选项中这些设备出 现的时间： box-set TVs 和The desktop computer 为1992 年

45、； The LCD TV 为2002年；The tablet 为2007年。可 知The tablet 为最新的设备，也意味着最省电。 (3) A few years ago, Paul Gerner began to gather a group of architects in Las vegas to ask them what it would take to design a public school that used 50 percent less energy, cost much less to build and obviously improved student le

46、arning. I think half of them fell off their chairs, Gerner says. Gerner manages school facilities(设施) for Clark county, Nevada, a district roughly the size of Massachusetts. By 2018, 143,000 additional students will enter the already crowded public-education system. Gerner needs 73 new schools to ho

47、use them. Four architecture teams have nearly finished designing primary school prototypes(样品); they plan to construct their schools starting in 2009. The district will then assess how well the schools perform, and three winners will copy those designs in 50 to 70 new buildings. Green schools are ap

48、pearing all over, but in Clark County, which stands out for its vastness, such aggressive targets are difficult because design requirements like more natural light for students go against the realities of a desert climate. One of the biggest challenges is getting the right site orientation(朝向), Mark

49、 McGinty, a director at SH Architecture, says. His firm recently completed a high school in Las Vegas. You have the same building, same set of windows, but if its orientation is incorrect and it faces the sun, it will be really expensive to cool. Surprisingly, the man responsible for one of the most

50、 progressive green-design competitions has doubts about ideas of eco-friendly buildings. I dont believe in the new green religion, Gerner says. Some of the building technologies that you get are impractical. Im interested in those that work. But he wouldnt mind if some green features inspire student
