Languages have been coming and going for thousands of years, but in recenttimes there has been less coming and a lot more going. When the world was stillpopulated by hunter-gatherers，small，tightly knit(联系)groups developed their ownpatterns of speech independent of each other. Some language experts believe that10,000 years ago, when the world had just five to ten million people, they spokeperhaps 12, 000 languages between them.
Soon afterwards, many of those people started settling down to becomefarmers, and their languages too became more settled and fewer in number. Inrecent centuries, trade, industrialisation, the development of the nation-stateand the spread of universal compulsory education, especially globalisation andbetter communications in the past few decades, all have caused many languages todisappear, and ____ languages such as English，Spanish and Chinese areincreasingly taking over.
At present, the world has about 6, 800 languages. The distribution of theselanguages is hugely uneven. The general rule is that mild zones have relativelyfew languages, often spoken by many people, while hot wet zones have lots, oftenspoken by small numbers. Europe has only around 200 languages; the Americasabout 1, 000; Africa 2, 400; and Asia and the Pacific perhaps 3,200, of whichPapua New Guinea alone accounts for well over 800.The median number(中位数) ofspeakers is mere 6,000, which that half the world's languages are spoken byfewer people than that.
Already well over 400 of the total of 6, 800 languages are close toextinction (消亡), with only a few elderly speakers left. Pick, at random, Busuuin Cameroon (eight remaining speakers), Chiapaneco in Mexico (150), Lipan Apachein the United States (two or three) or Wadjigu in Australia (one, with aquestion-mark): none of these seems to have much chance of survival.

We may think we’re a culture that gets rid of our worn technology at thefirst sight of something shiny and new, but a new study shows that we keep usingour old devices (装置)well after they go out of style. That’s bad news for theenvironment- and our wallets - as these outdated devices consume much moreenergy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt andher colleagues at the Rochester Institute of Technology in New York tracked theenvironmental costs for each product throughout its life - from when itsminerals are mined to when we stop using the device. This method provided areadout for how home energy use has evolved since the early 1990s.Devices weregrouped by generation. Desktop computers， basic mobile phones, and box-set TVsdefined 1992. Digital cameras arrived on the scene in 1997.And WP3 players,smart phones, and LCD TVs entered homes in 2002，before tablets and e-readersshowed 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, andsuddenly one day ，you have a TV in every room of the house,” said oneresearcher. The average number of electronic devices rose from four perhousehold in 1992 to 13 in 2007. We’re not just keeping these old devices - Wecontinue to use them. According to the analysis of Babbitt's team, old desktopmonitors and box TVs with cathode ray tubes are the worst devices with theirenergy consumption and contribution to greenhouse gas emissions (排放) more thandoubling during the 1992 to 2007 window.
So what' s the solution(解决方案)? The team' s data only went up to2007， butthe researchers also explored what would happen if consumers replaced oldproducts with new electronics that serve more than one function, such as atablet for word processing and TV viewing. They found that more on-demandentertainment viewing on tablets instead of TVs and desktop computers could cutenergy consumption by 44%.
32. What does the author think of new devices?

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?

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.
B. The tablet.
C. The LCD TV.
