【例】He didn’t cme t schl because he was ill.

1. because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。

【例】------Why aren’t ging there? ------Because I dn’t want t.
(2)because不能与并列连词s同时在句中使用。[任务型阅读-两者互换]
She was late fr schl because she missed the bus.

(3)because和because f 也有明显的区别。because后面要跟从句，而because f 后面要跟
名词短语。
【例】He is late fr schl ___ it rains heavily.
He is late fr schl the heavy rain.
2.As和since，因为语气较弱，一般用来表示明显的原因，常翻译成“既然”。由as和since引导的原因状语从居多放在句首。
【例】As he has n car, he can’t get there easily.
Since it is Sunday tmrrw, we can stay up late tnight.
注意：since cnj./prep意为 “自从...起”，引导的时间状语时，主句现完。
as的其他意思： cnj.当..时，随着；因为；正如 prep.作为
拓展：fr作为并列连词，也有“因为”之意，它用于引导原因状语从句时不位于句首，引导的分句并不说明前句行为发生的直接原因，只是对前面的内容加以说明、解释或推断。
【例】There must be n ne in the huse fr the dr is clsed. （推断）
