expressions of wishes/regret

how to teach expressions of wishes/regret?

[Tdol]

First of all, I'd choose a particular phrase and be clear on how it's used, as there are many ways of expressing regret.

The verb

regret

can be used in more than one way:

Regret + infinitive- where the speaker is regretful before the action:
I rgeret to say that your application has been unsuccessful.

Regret + gerund- where the speaker is regretful after the action:
I regret being so rude to her in the meeting yesterday.
