the letter are being returned by the book active sentence
Answers
Answer:
It is a sentence that contains modal verb and a main verb. So as per the rules the sentence structure consists of a subject that comes first, then one modal verb and one active verb in the middle and at the end there is an object. Now when we turn a sentence from active voice into passive voice ,first the object takes the place of subject. Here the object is “my book”. Then the modal verb comes and after that we need to add “be” and then the past participle form of the verb “return”. Here it should be mentioned that in passive voice and after the word the verb form always changes into it's past participle form. So after that there comes the word “by” and at last the pronoun form of the subject “he”. So the answer is “MY BOOK MUST BE RETURNED BY HIM”.
