because 最常用，用来回答以 why 开头的疑问句。
as 或 since 可以代替 because 引导原因从句，尤其是在书面语中，例如：
～This is a note about The National Portrait Gallery, as the word ‘Gallery’ can be misleading (这是关于 The National Portrait Gallery 的注释，因为 Gallery 一词容易令人误解）
～Since the juice is quite strong, you should always dilute it（这种果汁太浓，所以必须加以稀释）。
在故事中，for有时用于解释或论证，例如：
～He seemed to be in need of company, for he suddenly went back into the house（他看起来需要陪伴，因为他突然回到了屋里）。
注意，because是连词，用来连接一个句子中的两个观点：
～I'm unsocial, because of my deafness（我耳朵聋，所以不善交际）。本回答被提问者采纳
