CHANGE OF TENSE
It is very important to know how to change the tense of the reported speech. Let us know the rules.
Rule 1.
If the reporting verb is in preset or future tense, you need not change tense of the verb of the reported speech. Example:
1. Direct: Swaira says, ‘she reads a book.’
Indirect: Swaira says that she reads a book.
Explanation: as reporting verb (says) is in the present tense, tense of the reported speech has not been changed.
2. Direct: Swaira has said.’ She read a book.’
Indirect: Swaira has said that she read a book.
3. Direct: Swaira will say, ‘she wrote the book.’
Indirect: Swaira will say that she wrote the book.
Explanation: reporting verb (will) is in future tense, hence tense of the reported speech has not been changed.
