- 英譯漢 Who would have thought that, globally, the IT industry produces about the same volumes of greenhouse gases as the world’s airlines do — roughly 2 percent of all CO2 emissions? Many everyday tasks take a surprising toll on the environment. A Google search can leak between 0.2 and 7.0 grams of CO2 depending on how many attempts are needed to get the “right” answer. To deliver results to its users quickly, then, Google has to maintain vast data centres round the world, packed with powerful computers. While producing large quantities of CO2, these computers emit a great deal of heat, so the centres need to be well air- conditioned, which uses even more energy. However, Google and other big tech providers monitor their efficiency closely and make improvements. Monitoring is the first step on the road to reduction, but there is much to be done, and not just by big companies.

參考答案 誰(shuí)曾想到信息技術(shù)行業(yè)與航空業(yè)產(chǎn)生的溫室氣體總量不相上下——約占全球二氧化碳排放總量的2%？
許多日常工作對(duì)環(huán)境造成的危害大得驚人。每一次谷歌搜索能釋放0.2到0.7克的二氧化碳，釋放量的多少取決于使用者為了獲得“正確”答案搜索的次數(shù)。為了迅速向用戶提供搜索結(jié)果，谷歌不得不在世界各地建立大型數(shù)據(jù)中心，安裝大功率計(jì)算機(jī)。這些計(jì)算機(jī)不僅產(chǎn)生大量的二氧化碳，還釋放許多熱能，因此這些數(shù)據(jù)中心需要良好的空調(diào)設(shè)備，這又會(huì)耗費(fèi)更多的能源。
不過(guò)，谷歌和其他大型技術(shù)供應(yīng)商已經(jīng)在嚴(yán)密地監(jiān)控其數(shù)據(jù)中心的工作效率，并做出改進(jìn)。監(jiān)控只是減排的第一步，仍有太多問(wèn)題需要解決，而且這不只是由大公司的事情。

- 10 【英譯漢】 Most people would define optimism as being endlessly happy, with a glass that’s perpetually half fall. But that’s exactly the kind of false cheerfulness that positive psychologists wouldn’t recommend. “Healthy optimism means being in touch with reality.” says Tal Ben-Shahar, a Harvard professor. According to Ben-Shalar, realistic optimists are these who make the best of things that happen, but not those who believe everything happens for the best. Ben-Shalar uses three optimistic exercises. When he feels down—say, after giving a bad lecture—he grants himself permission to be human. He reminds himself that not every lecture can be a Nobel winner; some will be less effective than others. Next is reconstruction. He analyzes the weak lecture, learning lessons, for the future about what works and what doesn’t. Finally, there is perspective, which involves acknowledging that in the grand scheme of life, one lecture really doesn’tmatter.
