because、since、as 及 for 的区别
because可用来回答why提出的问题；可以引导表语从句；可用于强调句等，而其余三者则不行。
because表示的是必然的因果关系，语气最强，通常放在主句之后，若需强调则放在主句之前。
since、as所表示的原因是人们已知的，是对已知事实提供理由，而不表示直接原因。它们引导的从句通常放在主句之前，有时也放在主句之后。
- As he wasn't ready in time, we went without him. 因他未及时准备好，我们没等他就先走了。
- Since we have no money, it's no good thinking about a holiday. 既然我们没有钱，考虑度假有什么用。
至于for, 它是并列连词(其余三者为从属连词)，它有时可表示因果关系 (通常要放在主句之后，且可与because换用)；有时不表示因果关系，而是对前面分句内容的解释或推断 (也要放在主句之后，但不能与because换用)。试比较:
- The ground is wet, [for/because] it rained last night. 地面是湿的，因为昨晚下过雨。
- It must have rained last night, for the ground is wet this morning. 昨晚一定下过雨，你看今天早上地面是湿的。

时间点可以是具体的年、月、日期、钟点、1980、last month、half past six
- I have been here since 1989.
since + 一段时间 + ago
