Question

The teacher gave me a book to read
Change it in passive voice and explain how you change it

Answer 1

Answer:

A book was given to me by the teacher to read

Answer 2

Answer:

→ A book was being read by the teacher.

The question is in the active voice and we need to change it into passive voice.

The subject 'The teacher' was performing the action of 'reading a book'.

Starting with a book, as the question contains reading a book and not reading the book.

The question (active voice) has its voice in the past continuous tense (was reading). So we change the voice in such a way that the past continuos tense is maintained (was being read).

The question (active voice)  had the subject as 'the teacher' and not 'a teacher' or anything else, so the subject is maintained as it is when the voice is changed to passive.
