as,since,because既分別?(10點)

as, since, 和 because 都可解作 [因為]，但用法有點不同。

as 和 since 通常用來解釋前因所導致的後果。例如：
Since he was sick, he did not go to work yesterday.
As he was sick, he did not go to work yesterday.
因為他病了, 所以昨天沒上班。
前因是 [他病了]，導致的後果是 [他沒去上班]。

because 通常用來解釋一件事或行動的前因。例如：
He did not go to work yesterday because he was sick.
他昨天沒去上班的原因是他病了。
行動是：[他沒去上班]。前因是 [他病了]。

除此之外，as 和 since 都有 [既然] 或 [反正]的意思，例如：
Since I am already late, I might as well skip school today.
As I am already late, I might as well skip school today.
反正己經遲了，今天倒不如不上學了。

because 只解作 [因為]，而沒有 [既然] 或 [反正] 的意思。



希望能用得着。
