【问】 我查找了许多语法著作，得知as long as只能引导时间状语从句和条件状语从句。但无法解释下列句子：

As long as you're here，we might as well talk about your last game.

【答】 as long as除了引导时间状语从句和条件状语从句之外，还可以引导原因状语从句。上面问句中as long as从句便是一个原因状语从句，可以译为：“(由于，既然)你在这里，我们不妨谈一谈你的最后一次比赛”。类例：

1. As long as you act so mean，you can't expect anybody to do anything for you.

(由于)你行为卑劣，你不可能指望有人会来帮助你。

2. As long as you' re going，I'll go too. (LDCE)

既然你要去，那我也去。
