because, as, for, since

这四个词都可以作连词引导一个表示原因的状语从句。其区别是：

1.because是从属连词,引导的原因状语从句指的是自然、直接的原因,主句表示必然的因果关系,而原因构成句子的主要部分,是句子的重点。另外,because引导的从句多放在句末,但有时也可放在句首,这种情况往往是为了强调。

2.如果原因很明显或已为人们所知,或不如句子的其余部分重要,就用as或since,since比as更正式一些,这两个词都为从属连词,常译为“由于,既然”,语气比because轻。as和since引导的句子多放在整个句子的开头,偶尔它们引导的(特别是since引导的)句子也可以放在后面。since作为理由有“不好”或“勉强”的含意;而as只将既成事实作为理由,并不含有“不好”或“勉强”的意味。

3.for是并列连词,引导的是并列从句,表示原因的语气很弱,一般是对结果作推断性的补充说明或解释,不表示直接原因。for较正式,很少用于口语,一般用于书面语,前面一般多用逗号。

because of, due to

这两个短语都可表示“因为”“由于”，其区别在于：because of主要引导状语，偶尔导表语；而due to则主要引导表语，偶尔引导状语。

because of, for the sake of

这两个短语的词义并不相同，because of指原因或理由，常译为“因为”；而for the sake of则指利益或目的，常

译为“为了”。

as，because，for，since

这些连词均含有“因为”之意。

as从属连词，语意较because, since弱，着重在主句，所表示的原因或理由是“附带的”。

because从属连词，语意强，着重直接的原因或理由，所引出的从句是全句的重心，用以回答why提出的问题。

for并列连词，语气较弱，所引出的句子一般放在后面，表示附带说明的理由或推断理由。

since语意比because弱，但比as强，一般用于表示“由于大家已知的事实”。
