I was about to leave when it rain.
When asked the reason, the boy kept silent.
如果表示将来的时间，when 引导的从句就用现在时代替将来
I will call you when i arrive in Beijin.
when 还可以用在过去进行时的句子中。初二下册第三单元就学这个。
i was having dinner when my father entered.
同时，when可以用在过去完成时的句子中
the train had left when i arrived at the station.
从句是一般现在时，主句用一般将来时。
是的 个人见解
精锐金桥英语老师：
when引导的时间状语从句为过去一般时,可配合主句过去时的其它时态,现就提出的两种（也是最常用的两种）情况解释如下：
一、when引导时间从句用过去时,主句用过去进行时：表示在从句动作在过去发生时,主句的动作在当时也正在进行.用于表示在过去有两个动作同时发生的情况,或者一前一后即在过去某动作发生时或正在进行中,又有一个动作发生的情况（反之亦然）,通常短暂性动词用过去时,持续性动词用过去进行时.
when
i
got
up,my
mum
was
serving
breakfast.
when
i
was
having
breakfast,my
dad
went
out
of
home.
二、when引导时间从句用过去时,主句用过去完成时：表示从句动作在过去发生时,主句的动作在从句动作发生之前已经完成.
when
i
got
up,my
mum
had
already
(taken
breakfast
and)
left.
三、关于when引导的时间状语从句用去过时,主句用过去的其它时态,可自行列句进行对比分析.
