Active and Passive Voice- Interrogative Sentences and Transitive Verbs having two Objects

AUXILIARY AND MODAL VERBS

• If the question in the Active Voice begins with a Helping verb or Modal Verb, the Passive Voice must also begin with a suitable Auxiliary or Modal verb (or tense).

A.    Auxiliary verbs

***Auxiliary verbs (do/does/did)***

Shall	Should

                        subject            verb                  object 1          object 2
