1、because引导的原因状语从句一般放于主句的后面，because从句位于句首时要用逗号分开，放在句末 时，可不用逗号分开。because表示直接原因， 语气最强， 最适合回答why引导的疑问句。
2、since引导的原因状语从句一般放于主句之前表示已知的、 显然的理由（通常被翻译成“既然”）， 较为正式， 语气比because弱。
注意： seeing (that)， now (that)， considering (that)， in that这几个词汇与since引导的原因状语从句意思相近， 都表示“既然”。
3、as 引导原因状语从句时表示附带说明的“双方已知的原因”， 语气比since弱， 较为正式， 位置较为灵活(常放于主句之前)。例如：As it is raining, you’d better take a taxi.既然在下雨， 你最好乘出租汽车。
4、for引导的是并列句表示原因但并不说明主句行为发生的直接原因， 只提供一些辅助性的补充说明， for引导的并列句只能放于主句之后并且必须用逗号将其与主句隔开。
原因状语从句是状语从句中较为简单的一种，是用于解释事件发生原因的状语从句，引导原因状语从句的从属连词有because, as, since, considering （that）, given （that）等。 扩展资料
1、because的用法：because通常表示直接的原因。because引导的从句表示直接而明确的原因和理由，表示按因果关系的推断，语气很强，用来回答why的问题，一般位于主句之后。eg. We couldn't go out because these robber are still outside.
2、for的用法：for是并列连词，引出的原因较间接，似乎是事后所想到的.补充解释的理由，只陈述一般推断的理由，不一定表示产生结果的必然原因，主要放在两个并列句之间。eg. It must be raining for lots of people running on the street.
4、now that(既然)的用法：now that同since相似，语气较弱，强调人们已知的事实。eg. Now that you are busy, you can give up this trip. 既然你很忙，你可以不去这个旅行。
5、because, since, as和for的比较① because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since。② 由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。③ 用于强调句型时和被not所否定时都只能用because。
