because语气较强，用以回答why问句
as语气较弱，较口语化，所表示的原因较明显。
since语气较弱，常表对方已知的事实，相当于汉语的“既然”。

结果状语从句常用so that, such that等关联词引导。e.g.

It’s such a good chance that we mustn’t miss it. 机会这样好，我们决不能失掉。so that, so…that, such…that so that　“以便”、“结果”表目的和结果。
注意：在从句中有情态动词表目的。无情态动词表结果。 　so…that “如此的…以致于”表结果。该结构常见于： 　　1.so+形／副＋that　　　　2.so+形＋a(an)＋单数名词＋that　　　　3.so＋many/much＋复数名词（不可数名词）+that
such…that　“如此的…以致于”表结果。该结构常见于： 　　1.such＋a(an)＋形＋名词＋that　　2.such＋形＋复数名词／不可数名词＋thatso that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, could, may, might等。2)从意思上看，目的状语从句往往表示的目的很明确。例如：
Speak clearly so that they may understand you. (目的状语从句)
