Emphatic Imperative

 Imperative clauses are used  when people tell someone else to do something (an advice, a suggestion, a request, a command…).

Emphatic imperatives are mostly used for polite requests.
{See Present and Past Emphatic Tenses, Level B1}

We can make emphatic imperatives using do + infinitive.

• All people please do stay still.
• Passengers do put your seatbelts slowly.
• You are going fast please do slow.

We usually use emphatic imperative in polite requests, complaints and apologies.

Sometimes we add the pronoun you to imperatives, to emphasize it or to show the receiver of the imperative.
