【正确答案】Nowadays, 3D printing can be used almost everywhere. Consumers can acquire the design proposals from the Internet and then print them at home. If your kids want new toys, your parents want to play chess, or you want a new cup, all you have to do is download some drawings and then "print" them by your printer at home. It is hard to predict every great invention’s influence when it is first invented, such as the electric light, steam engine and printing. Similarly, we can hardly predict how this new technology, acclaimed as "the Third Industrial Revolution" by The Economist, will quietly change the world we live in.

【答案解析】1. 第二句中，“设计方案”是一个名词短语，可译为the design proposals。2. 第三句较长，首先要分析一下句子的逻辑结构。“如果……新杯子”为列举的几个例子，翻译时可用条件状语从句将其列出。句中的“下载……出来”可以处理为表语。3. 翻译第四句时，为避免句子头重脚轻。可将其译为“It is hard to predict every great invention’s influence…and printing. ”以符合英文的行文习惯。4. 末句中，“被《经济学人》称为‘第三次工业革命’的”可以处理成后置定语，译为acclaimed as“the Third Industrial Revolution”by The Economist，这样更符合英语的语言特点。
