使用“as”的时候要注意以下几点:
* “as”用于比较时,可以用于同类比较,也可以用于不同类比较。例如,“as I expected”表示如我所预料的那样。 * 当表达突然或意料之外的事情时,通常会使用“just as ... was happening”或类似的表达方式。例如,“Just as we were about to start the journey, the rain began.” * 当想强调某一情况发生的短暂性或偶然性时,也会使用“as + 时间词”的句型。
例如:“I met him just as I was leaving the room.”(我刚要离开房间就碰到了他。)这样的表达方式可以强调事件发生的突然性和短暂性。
