汉译英
随手关灯的道理人人都懂,却都仅仅认为它是为了节约电费.其实,每节约1度电就会少消耗400克煤,少排放约1千克的二氧化碳和30克的二氧化硫.随手关灯的价值远不只是那点电费.
答
Although everybody knows about the need to switch off the lights, it is done all for the sake of reducing the power ill. Actually, with every degree of electricity saved,400 gram less coal will be consumed while 2000 gram less carbon dioxide and 30 gram less sulphuric dioxide will be released. So, the advantage of switching off the lights is not limited to just saving a little bit of the fuel charges.
