reason著重指解釋或說明某事發生的理由或原因,
cause著重指產生或造成某事發生的原因,往往指造成不好的影響.下面見兩個例子：
1.The reason for which he was late was that he got up late.
2.The cause of the accident was his carelessness.
cause用於表示具有明顯因果關係的原因。reason有時能與cause換用，但上下文必須有能夠查得出的或可以解釋得出的因果關係。
如果某“結果”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，還是對噪音的抱怨僅僅是一種症狀呢？
Every effect must have an adequate cause. 每一種結果都必須有充分的原因。
reason通常含有“理由”的意思 They are trying to find out the reason (or cause) of the terrible fire. 他們正在努力查尋那次可怕的火災的原因。
