e.g.I was discussing a math problem with Joe when Mike called me up.

e.g. I’ll call you when I arrive in Shanghai.

(1) 指时间段，其从句的谓语动词必须是延续性的。
e.g.Love your parents while they are alive. Don’t wait until it is too late.
请在你的父母健在的时候爱他们，不要等到一切都太迟了。
(2) 强调主句动作发生时，从句动作正在进行，常用while引导从句。主句常用一般过去时或一般现在时，从句常用进行时。
e.g. 当我正在河边钓鱼时，我看到附近有一条空船。
