Из теста нужно сделать прямую речь
Read the rules by Miss Stevenson and write the exact words. Change reported speech into direct.

Miss Stevenson told her pupils not to talk when she’s talking. She told them to give their homework to her at the end of each lesson. She asked them not to write on the desks. Then she told them to put their hands up if they had questions. She also asked them not to eat in the classroom. She told them not to leave the classroom without permission.
