cause用于表示具有明显因果关系的原因.reason有时能与cause换用,但上下文必须有能够查得出的或可以解释得出的因果关系.
如果某“结果”是不言而喻的,也可以用reason表示“原因”,如:
Was the noise a cause of the illness,or were the complaints about noise merely a symptom?噪音是病因呢,还是对噪音的抱怨仅仅是一种症状呢?
Every effect must have an adequate cause.每一种结果都必须有充分的原因.
reason通常含有“理由”的意思 They are trying to find out the reason (or cause) of the terrible fire.他们正在努力查寻那次可怕的火灾的原因.
