Как преобразовать прямую речь в косвенную (Reported Speech)?

Основные изменения при переводе в Reported Speech:

1. Сдвиг времён (если глагол вводящий — в прошедшем времени):

2. Изменение местоимений — по смыслу.

• I → he/she, my → his/her, we → they, you → I/he/she/they.

3. Изменение указателей времени и места:

• now → then
• today → that day
• tomorrow → the next day / the following day
• yesterday → the day before / the previous day
• here → there
• this → that
• these → those

Примеры:

• He said, "I am tired." → He said (that) he was tired. — Он сказал, что устал.
• She said, "I am working now." → She said she was working then.
• They said, "We will help you tomorrow." → They said they would help me the next day.
• Tom said, "I have finished my homework." → Tom said he had finished his homework.

Если вводящий глагол в Present (says) — времена не меняются:

• He says, "I am tired." → He says (that) he is tired.

Универсальные истины не сдвигаются: The teacher said that water boils at 100°C.
