For imperatives, we use "ask/tell somebody to do something".
Compare these two sentences and how they are used in reported speech.
Statement: "It is good."
Reported Speech: He said that it is good.
Imperative: "Come here."
Reported Speech: She told me to come here.
So, we use "ask/tell + to + verb" to report a command or imperative.
- "Be quiet."
The teacher told the students to be quiet. - "Sit down."
My boss told me to sit down. - "Wake up early."
She told me to wake up early. - "Please stop it."
He asked her to please stop it. - "Bring it, please."
He asked her to bring it, please.
For negative imperatives, we use "not to + verb". However, you will often hear native speakers say "to + not + verb".
- "Don't do that."
She told me not to do that. - "Do not talk."
She told us not to talk. - "Please do not be late."
She asked me not to be late. - "Don't be noisy."
I told her not to be noisy.
