Reported speech is another name for "indirect" speech. Indirect speech is when someone is reporting on the details of a situation without using the direct quotation of that person. You wouldn't want to use quotation marks around "he was really hungry" and powerranger wouldn't use quotation marks, either. Reported speech or indirect speech both use the third person tense of verb in order to communicate. It is as if someone outside of the situation is reporting the details of another person's situation. The following are the answers to the sentences:
1. John said he is really hungry.
2. She said that the fish smells awful.
3. He said he doesn't like ice cream.
