Knowing the exact direction from which a sound is coming from requires the use of the difference in timing that a sound reaches their two ears.
【词汇突破】exact 确切的
time 计算时间
【参考译文】要知道声音来自的确切方向,需要利用声音到达两只耳朵的时间差。
【结构分析】“Knowing the exact direction from which a sound is coming from”是动名词做主语,from which a sound is coming from是定语从句修饰the exact direction;“requires”是谓语动词;“time”在这里做动词,表示“计算……的时间”,后面接了一个that引导的宾语从句。
