When we want to investigate why something hashappened, it is not enough to just look at thesuperficial connections. Instead, we try to discoverthe underlying causes. For example, if the workersat a factory are on strike, we want to know what thereasons are that lie below their actions, that give riseto their discontent. We are looking for somethingbasic at the very beginning level of a problem ormystery. Everything else builds upon thatfoundation.

当我们调查一些事情发生的原因时，只看表面的联系是不够的。相反，我们要努力找出深层次的原因。例如，如果一家工厂的工人举行罢工活动，我们要知道是什么原因导致了罢工，是什么原因造成了他们的不满。我们在问题或难题出现之初就寻找其根本原因。一切都建立在这个基础之上。

Therefore, when we say that we want to "get to the bottom of" something, it means we want todig deeply (using brain power and words, not shovels) to the most fundamental root causes ofa problem or mystery. Wewant to know the truth. Only then can we feel truly satisfied that weunderstand what is really going on.

因此，当我们说，我们要“挖出真相”的时候，它意味着我们要深入挖掘(使用脑力或者言辞而不是铲子之类的具体工具)该问题或难题的根源。我们想知道事情的真相。只有这样我们才能真正感到满意——因为我们明白究竟是怎么回事了。
