A command is an imperative statement. One person orders another to do something. It can be preceded by please. The understood subject is you. Use the simple form of the verb.
- Close the door.
- Leave the room
- Open your book
- Be quite.
There are 3 types of commands:
* Negative commands: A negative command is formed by adding the word don’t before the verb.
- Don’t close the door.
- Please don’t turn off the light
- Don’t open the window.
* Indirect commands: Usually the verbs order, ask, tell, or say are used to indicate an indirect command. They are followed by the infinitive (to+verb).
- John told Mary to close the door.
- Jack asked Jill to turn off the light.
- The teacher told Christopher to open the window.
- Please tell Jaime to leave the room.
- John ordered Bill to open his book.
- The policeman ordered the suspect to be quiet.
*Negative indirect commands: To make an indirect command negative, add the particle not before the infinitive. Look at the following formula:
Subject + Verb + Complement + not + (verb in infinitive).
- John told Mary not to close the door.
- Jack askednot to turn off the light.
- The teacher told Christopher not to open the window.
- Please tell Jaime not to leave the room.
