Orders are things you ask somebody else to do. Statements, on the other hand, are things you just say, your opinion for example or something that has happened to you.
Orders in indirect speech: "to tell" + object (the person the order was directed to) + infinitive with "to" or "not to"
That might sound complicated, but it is really easy. It would be best if you just looked at the examples very carefully:
Lena: "Remember to switch off the oven before you leave, Lucas." Lena told Lucas to remember to switch off the oven.
Mr Lies: "Don't forget your lunch, Sammy." Mr Lies told Sammy not to forget her lunch.
Now let's do some work! Try to transform the sentences below into indirect speech! You do not need any commas, and every sentence in reported speech ends with a full stop.
