How It Helps Your Business English

What this resource offers:

The video runs just under ten minutes. It takes can, could and must in turn: skills and informal permission, polite requests and past ability, requirements and logical deductions. Three grammar rules for modal verbs follow, the examples come from emails to clients, project planning, human resources and compliance, and ten practice questions with explanations end the lesson.

How to use this resource:

You watch once through for the three modal verbs, then go back to the examples and read them aloud. Stop at the ten practice questions and answer each one before the explanation is given, so that you find out which use you are still unsure of. The workplace sentences can be reused in your own emails with the names changed.
