Question

Exercise D Change the following sentences into passive voice: 1. Have you kept the secret? 2. Why have you told a lie? 3. Have you written the letter? 4. Who has torn my book? 5. 6. Who has done this? 7. Has the postal department released a new stamp? 8. How do you prepare tea? Has the policeman caught the thief?​

Answer 1

Sure, here are those sentences transformed into the passive voice:

1. Has the secret been kept by you?
2. Why has a lie been told by you?
3. Has the letter been written by you?
4. By whom has my book been torn?
5. This has been done by whom?
6. This remains unchanged as it's already in the passive voice.
7. Has a new stamp been released by the postal department?
8. How is tea prepared by you? (This one doesn't have a passive form because it's an instructional question.)

And the last sentence:
9. Has the thief been caught by the policeman?
