I am teaching about participial phrases these days, and all examples I am able to find online have the phrases paired with simple tenses. For example:
Removing his glasses, Kent Clark quickly put on his cape.
Running up to the boy, the dog hopes that he will have a treat.
Eaten by mosquitos, we wished that we have stayed at home.
I seldom see participial phrases paired with a continuous tense, thus I want to know if there's a rule to this.
For example:
Watching the crime happening, I was calling the police for help.
Is this possible we use the past continuous for the clause, or we must use the simple past tense?
