for和because表示原因時,用法有何區別

熱心網友

because表直接的原因,語氣最強.Becauseheisill, r表間接原因,用來補述內容.放在主句后.語氣最弱.Hemustbeill,forheisabsenttoday.在強調句型中,引導從句只能用because,不能用forItwasbecausehewasillthathedidn’tgowithus.

because是一個從屬連詞.引導原因狀語從句,直接回答why的問句.而for是一個并列連詞,它引導的句子雖然可以翻譯成"因為",但是它只是對前面的句子做進一步的補充說明,沒有直接的因果關系.請比較下面的句子:Why are you late again? Because I missed the bus.Sorry, I'm late today, for (you know) I have to send my child to the school first.

for 不能用于句子的開頭，而because 可以。

because更正式。后面可以加比較長的原因。for一般后面不會跟很長的句子。e.g.your question couldn't be answered because you didn't give the context for translation.your question couldn't be answered for an obvious reason.
