A ball has no power by which it can put itself
问题详情
A ball has no power by which it can put itself in motion but as soon as you throw it,you impart energy to it and this is why it speeds through the air.
参考答案
球本身并不具有使其进入运动状态的动力，但你一掷它，就给了它能量，这就是为什么它快速飞入天空的道理。句中大量使用了直译法。第一句中的定语从句的翻译就是一个例子，power which it can put itself in motion翻译为“使其进入运动状态的动力”。句子的结构、词汇的含义没有作很大的调整，达到了最佳的翻译效果。
