How do you change active voice into passive voice?
The object of the active sentence becomes the subject of the passive sentence.
The verb remains in the same tense, but a form of to be or to get is inserted.
The agent can be included with the preposition by, if necessary.
Martians destroyed Earth.
Earth was destroyed.
Earth was destroyed by Martians.
Some verbs, such as offer, promise, give, send, allow, bring, tell, and throw, can take two objects, and you can make two different passive sentences with them, using each object as a subject.
Martians offered London a chance to escape.
London was offered a chance to escape.
A chance to escape was offered to London.
Martians gave London to Venus.
London was given to Venus by Martians.
