虚拟条件句

If I were you……的假设是一种不可能发生的情况，因为“我永远不可能是你”，所以这种句式里的语气就是虚拟语气了。“虚拟”的本质是对“不会出现、不会发生”的情况的一种假设。

1.对现在的情况进行虚拟假设。

公式：if I were you，主语+ would(should、could、might)+ do

2. 对过去的情况进行虚拟假设。

公式：if I were you, 主语+would(should、could、might)+have done.

3. 对未来的情况进行虚拟假设。

公式：if I were you, 主语 +would(could、should、might)+ do

If I were you, I'd probably go.

If I were you, I would not have missed the film yesterday.

如果我是你，我就不会错过昨天的那部电影。
