Hello. Happy new year to all.
I would be very grateful if you could tell me whether the following statements have been reported correctly. If not, please explain why. The statements are from a book taught to the secondary stage.
1) "I must leave now."
Answer 1: He said that he must leave now.
Answer 2: He said that he had to leave then.
2) "I must leave tomorrow."
Answer 1: He said that he must leave tomorrow.
Answer 2: He said that he would have to leave the following day.
If the two answers are correct, does this only apply to "must"? Or do we generally not backshift any other verb if we do not change the time words (like NOW) or place words (like HERE) when reporting? Please explain with examples.
Thanks in advance.
