past continuous

I was wondering if you could explain something about the past continuous.

I understand that normally when we use while it is in the past continuous and when we use when it is in the past.

I understand the interrupted action and the simultantious action.

What I want to know is if it is possible to use while in the past and when in the continuous. Could you please give me some examples.

Thank you.

Hi Giovanni,
You can use WHILE with a past simple sentence but with a verb that means a duration in the past;
Example; While I was in New York, I worked at an Italian restaurant.
Here in this example it is obvious that the verb “was” shows a duration, but not just a point of time in the past. So “while” is not necessarily followed by a continuous verb or a verb with “-ing” but a verb with a meaning of continuity.
I hope this helps you.
