How do you form passive to active voice?

For changing from passive to active voice sometimes the object is understood. In that case the object has to be mentally supplied and then formed into the subject. Thus :- 'It is said he will come' while converting from passive to active will read like this 'Men say he will come'.



In passive sentences the doer of the verb is not usually given. Or if it is given then it is - by + noun

, this is called the agent eg

The mouse was chased by the cat

.

The agent becomes the subject of an active sentence eg:

The cat

chased the mouse.

If the agent is not given in the passive sentence you to find out who or what does the action to make passive into active. eg

The Mona Lisa was painted in the 16th century. -- passive

_________ painted the Mona Lisa in the 16th century. -- active.
