Объяснение:

в косвенной речи согласуются времена, а также меняются наречия и местоимения

Согласования времен: present simple ⇒ past simple

present continuous ⇒ past continuous

present perfect, past simple, past perfect ⇒ past perfect

present perfect continuous, past perfect continuous, past continuous ⇒ past perfect continuous

future ⇒ future-in-the-past (will ⇒ would)

this ⇒ that

these ⇒ those

tomorrow ⇒ the next day

yesterday ⇒ the day before

и так далее

модальные глаголы, например, can, shall, will становятся соответственно could, should, would. Но если они изначально были в прошедшем времени, то мы их никак не меняем
