- 英译汉 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.

参考答案 谁曾想到信息技术行业与航空业产生的温室气体总量不相上下——约占全球二氧化碳排放总量的2%？
许多日常工作对环境造成的危害大得惊人。每一次谷歌搜索能释放0.2到0.7克的二氧化碳，释放量的多少取决于使用者为了获得“正确”答案搜索的次数。为了迅速向用户提供搜索结果，谷歌不得不在世界各地建立大型数据中心，安装大功率计算机。这些计算机不仅产生大量的二氧化碳，还释放许多热能，因此这些数据中心需要良好的空调设备，这又会耗费更多的能源。
不过，谷歌和其他大型技术供应商已经在严密地监控其数据中心的工作效率，并做出改进。监控只是减排的第一步，仍有太多问题需要解决，而且这不只是由大公司的事情。

- 10 【英译汉】 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.
