[ 一语击破 ] because 作连词，用于引导原因状语从句或回答 why 的问句，常用于表示直接的原因。而 because of 是复合介词，后接名词或代词。请比较：
He didn't come because he was ill .
He didn't come because of his illness .
since 的语气比 because 稍弱，表示关系上的自然结果，常译成“既然、鉴于”，如：
Since light travels faster than sound ， we see lightening before we hear the thunder.
as 语气最弱，只说明一般的因果关系，译为“由于”； for 表明附加或推断的理由，引导的分句前常有逗号， for 分句不放在句首。如：
He must be ill ， for he is absent today .
