Question

she invited him to her house yesterday ( change this into passive voice )

Answer 1

Thank you for asking the question!
He was invited by her at her house yesterday.
The change of tense is very important while we are changing active voice into passive voice. There are some conditions which needs to be kept in mind while we are changing active voice to passive voice. First, we have to change pronouns into possessive nouns. Then the form of verb must be changed. Then the tense it must be changed into past tense. However,The sentence with actions words cannot be changed into passive voice.
Hope it helps.

Answer 2

In a sentence with an active voice, the subject performs the action which is denoted by the verb. In other words, the subject is the doer of the action. Whereas in a passive voice, the subject is not active but by the verb is acted upon.

Passive voice is the voice used to show an interest in the object or person who experienced the action rather upon the action performer. In passive voice, a subject is an important thing.

The sentence when written in passive voice, it would be written as:

He was invited by her at her house previous day.
