原文：Spacecraft and satellites are extremely expensive to launch using currently available methods,which has significantly limited the commercial use of space.译文：发射宇宙飞船和卫星非常品贵，用现有的方法大大限制了对太空的商业化利用。改译：
【正确答案】：应用现有的方法发射宇宙飞船和卫星，费用极其昂贵，这大大限制了对太空的商业利用。【解析】原译文对英汉翻译中状语和定语的处理不当，造成译文错误。using currently available methods在原句中作方式状语，修饰动词launch，汉译时应把后置的状语提前，译作“用现有的方法发射……”。而which引导的非限制性定语从句修饰的是前面整句话的内容，而非using the currently available methods。
