We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.
我们都经历过：在电梯里，在银行排队，或者在飞机上，周围都是像我们一样专注于手机的人，或者更糟糕的是，在令人不拿芹安的沉默中挣扎。
What’s the problem? It’s possible that we all have compromised conversational intelligence. It’s more likely that none of us start a conversation because it’s awkward and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s an invaluable social practice that results in big benefits.
问题是什么呢？有可能我们每个人都不善于开口说话。
C
Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit (联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.
Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialisation, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.
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 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 mere 6,000, which means that half the world's languages are spoken by fewer people than that.
Already well over 400 of the total of 6,800 languages are close to extinction (消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon （eight remaining speakers), Chiapaneco in Mexico (150), Lipan Apache in the United States (two or three) or Wadjigu in Australia (one, with a question-mark): none of these seems to have much chance of survival.
28. What can we infer about languages in hunter-gatherer times?
A. They developed very fast.
B. They were large in number.
C. They had similar patterns.
D. They were closely connected.
29. Which of the following best explains "dominant" underlined in paragraph 2？
A. Complex. B. Advanced. C. Powerful. D. Modern.
30. How many languages are spoken by less than 6,000 people at present？
A. About 6,800. B. About 3,400. C. About 2,400. D. About 1,200.
31. What is the main idea of the text？
A. New languages will be created.
B. People's lifestyles are reflected in languages.
C. Human development results in fewer languages.
D. Geography determines language evolution.

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 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.
我们可能认为，在我们的文化中，一看到崭新的事物就会摒弃我们的旧技术，但一项新的研究表明，当旧设备过时了之后我们仍然继续使用。这对于环境和我们的钱包来说是个坏消息，因为这些过时的设备做同样的事情要比新设备消耗更多的能源。
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.
为了弄清楚这些设备的耗电量，纽约罗切斯特理工学院的卡莉·巴比特和她的同事跟踪了每种产品在其整个生命周期内造成的环境代价——从原料开采到停止使用该设备。
