 ♣ as a matter of fact, as good as, as it is
　这三个短语都有“实际上，事实上”的意思，其区别是：as a matter of fact含有对比之意，说的是与已知的或已说过的内容不同的内容；as good as没有对比的意味，意思是“实质上差不多等于”;as it is则用于指出即将说的是一个事实。例如：
　Mike said he didn't tell a lie. As a matter of fact, he did.　迈克说他从没有说过谎。事实上，他说过。
　He as good as refused.　他实际上等于拒绝了。
　We had hoped to finish today, but as it is we probably won't finish until tomorrow.　我们原本希望今天能做完它，但实际情况是我们或许要等到明天才能做完。
 ♣ as, because, for, since
　这四个词都可以作连词引导一个表示原因的状语从句。其区别是：
1. because是从属连词，引导的原因状语从句指的是自然、直接的原因，主句表示必然的因果关系，而原因构成句子的主要部分，是句子的重点。另外，because引导的从句多放在句末，但有时也可放在句首，这种情况往往是为了强调。
2. 如果原因很明显或已为人们所知，或不如句子的其余部分重要，就用as或since, since比as更正式一些，这两个词都为从属连词，常译为“由于，既然”，语气比because轻。as和since引导的句子多放在整个句子的开头，偶尔它们引导的（特别是since引导的）句子也可以放在后面。since作为理由有“不好”或“勉强”的含意；而as只将既成事实作为理由，并不含有“不好”或“勉强”的意味。
3. for是并列连词，引导的是并列从句，表示原因的语气很弱，一般是对结果作推断性的补充说明或解释，不表示直接原因。for较正式，很少用于口语，一般用于书面语，前面一般多用逗号。
 ♣ as it is/was, as it were
　as it is/was　是个短语，意思是“实际上”“事实上”“照目前情况来看”，用于把可能的情景与实际发生的情况进行对比；而as it were的意思则是“可以说是”“似乎是”“仿佛”，表示所说的话听起来不那么肯定。
 ♣ as, though
　这两个词用作从属连词引导让步状语从句时，都可采用倒装语序。其区别在于：as采用这种倒装语序是强制性的，而though则是非强制性的。此外，as引导的这种倒装语序还可表示原因，而though则无此功能。
 ♣ as, when, while
　这三个词都可作连词引导一个表示时间的状语从句。as引导的从句作“当…时”或“和…同时”解，从句中的动作与主句中的动作同时发生或同时进行，一般持续时间不长；when引导的从句作“当…时”或“每逢…”解，从句中的动作既可以和主句中的动作同时发生，也可以在主句的动作之前或之后发生；while引导的从句作“当…时”或“在…期间”解，它强调从句中的动作与主句中的动作同时发生，但持续时间一般较长或主句的动作在从句的动作过程中发生。while与as和when的最大区别在于有时含有“趁着…情况的存在赶紧做某事，否则来不及了”的意味。
 ♣ as well, also, besides, either, moreover, too
　参见too条。
