Modal Verbs (part 2) - PERFECT MODALS

If you remember, I previously published a post about Modal Verbs. Those were simple modal verbs, whereas these new ones are perfect modal verbs. They are used to talk about past actions. In order to know more about them, please, watch the following explicative videos and then, try to complete the exercises. I promise you they are easy peasy! ;)

You can find really helpful explanations and exercises here:
