Read the different verb forms where they remain the same in the direct and indirect speech in the following cases. Fill in the blanks with missing indirect speech.
1. If the reporting verb is in the present tense.
2. When we report a universal truth (something that is always true)
3. With modal verbs would, might, could, should, ought to, used to.
4. With would rather, had better I would rather fly.
5. In if-clauses and time-clauses.
6. We do not usually change the modal verbs must and needn’t. But must can become had to or would have to and needn’t can become didn’t have to or wouldn’t have to if we want to express an obligation. Would/wouldn’t have to are used to talk about future obligations.
