Interrogative Voices with who

There are the voices that are of some interrogative sentence. They are all converted into passive voice in accordance with the rules already mentioned in the previous page.

The Rules

  1. Convert Subject into Object
  2. Convert Object into Subject
  3. Use 3rd form
  4. Use by with Objects

These are the same rules used for the simple voices. Remember, you have to make interrogative in passive voice exactly as you make interrogative in tenses.

Examples

  • They are taking their classes. (active voice of positive sentence)
    Their classes are being taken by them. (passive voice of positive sentence)
  • Are they taking their classes? (active voice of interrogative sentence)
    Are their classes being taken by them? (passive voice of interrogative sentence)
  • How are they taking their classes? (active voice of interrogative sentence)
    How are their classes being taken by them?
    (passive voice of interrogative sentence)

You have seen that the passive voice is converted into interrogatives exactly as you convert the simple sentence. It is the rule of tenses to make interrogative by adding auxiliary (helping verb) at the beginning of the sentence and same is the case in passives, but for the passives start with who the rules are bit different.

Rules for the Interrogative with who
Whenever the interrogative with who is converted into passive voice there is a bit different rule to be applied, whereas all the other rules are the same.

  • By is used at the beginning with whom. Since who is the subject and it converts into whom in passive voice.

    By whom am I being called? (passive voice)
