Answer 1

I had just locked the door ___when___ I realised I had left my key on the kitchen table .

例1：He said the train was leaving at six the next morning.他说火车第二天早晨出发。

例2：She told me she was coming to see me.她告诉我她要来看我。

四、特定场合的一般过去时可表示过去将来时

条件状语从句和时间状语从句中须用一般过去时代替过去将来时。

用法：

一、"would+动词原形"表示过去将来时。

"would+动词原形"构成过去将来时，常表示根据计划或安排即将发生的事。

例1：He said he would come to see me.他说他要来看我。

例2：He told me he would go to Beijing.他告诉我他将去北京。

二、"was /were+going to+动词原形"表示过去将来时

"was /were+going to+动词原形"也可表示根据计划或安排即将发生的事。

例1：She said she was going to start at once.她说她将立即出发。

例2：I was told that he was going to return home.他告诉我他准备要回家。

"was /were+going to+动词原形"还可表示根据当时情况判断有可能但不一定会发生某事。

例：It seemed as if it was going to rain.看来好像要下雨。

Answer 2

首先,when在这里的用法很特别，它是并列连词=and then
——这一点很重要！
其次记住一下规律：
1. ...was/were doing...when sth. did...
2. ...was//were about to do...when sth. did...
=...was//were on the point of doing...when sth. did...
3. ...had just done..when sth. did...
因此在以上句型中while\once都是不可以考虑的。

Answer 3

1 be about to do...when 是表示将来时的，但它的时态没有具体的规定，根据语境来选。
2 学单词，首先要记他们的基本意思。单词区分首先在意思上，once是“一旦；一次”的意思，since是“自从”，后面可以接短语也可以接句子。while和when容易混淆，但while强调的是时间段，when强调的是时间点。而且while更强调主从句的两个动作同时进行。比如，I was reading a book when he came into the room.
I was reading a book while he was listening to the music.
