Question

we saw a good book yesterday.

[change into voice]​

Answer 1

Passive voice:

A good book was seen by us yesterday.

Explanation:

• The object of the active voice becomes the subject in passive voice. Since "a good book" is the object in active voice, it is the subject in passive voice now.
• The next part comes for auxiliary verbs. The given active voice is Past Indefinite Tense, so according to the passive voiced subject "a good book", we write "was" for singular number, else we write "were" for plural numbers.
• Then we find the main verb "read" whose past participle form "read" is to be written.
• The subject "We" of the active voice is now the object in passive voice and to wrote this, we take "by us" in place of "we".
• The remaining words to mention time or place will be written as it is.
