E. Direct ↔ Indirect (Narration) — Key Rules

Remove inverted commas; change reporting verb as needed (says/say → says/say; said → said/told).

Pronoun changes based on subject/object of reporting verb.

Tense generally shifts back one step (present → past, past → past perfect) if reporting verb is in past tense.

Time/place words change: now→then, today→that day, here→there, tomorrow→the next day, yesterday→the day before, this→that, these→those.

Statements: use "that"; Questions: use if/whether or wh-word, no question mark, change to assertive word order; Commands/Requests: use "to" (+not for negative); Exclamations: express feeling with words like "with joy/sorrow" + that.

Examples:

Direct: She said, "I am going to school."

Indirect: She said (that) she was going to school.

Direct: He said to me, "Where do you live?"

Indirect: He asked me where I lived.

Direct: The teacher said, "Keep quiet."

Indirect: The teacher ordered/told us to keep quiet.

Direct: She said, "What a beautiful flower it is!"

Indirect: She exclaimed with joy that it was a very beautiful flower.

F. Active ↔ Passive Voice

Active: The chef cooks delicious food.

Passive: Delicious food is cooked by the chef.

Active: She has completed the project.

Passive: The project has been completed by her.
