Doing some exercises about the passive transformation (rewrite sentences from active to passive), I came up against some problems.
The problem sentences are:
- Martin always wears casual clothes
I wrote: Casual clothes are always worn by Martin. But it's wrong. The author's book says: Not possible to rewrite the sentence. But I can't understand why.. If the sentence were: "Casual clothes are worn always by Martin", (maybe) I would change the meaning of the sentence.. It would seem like "Martin is the unique person wearing casual.."
- Most of the guests had left the hotel by midday.
My sentence: The hotel had been left by most of the guest by midday.
Author's opinion: Not possible to rewrite the sentence. Again, I can't understand why...
- Some parents read to their children every night.
My answer: Not possible to rewrite the sentence, because no object of 'read' is given in the sentence, so it's intransitive. Author's answer: Some children are read to by their parents.
I reviewed the examples in the book and
They sent me a letter -> A letter was sent to me. But it's not my case, because here the verb has an obj.
People shouted at the Prime Minister -> The Prime Minister was shouted at. Here the verb is intransitive (like in my case).. Do I have to conclude that if the verb is intransitive and it is followed by a preposition, I can always rewrite the sentence from active to passive?
(I'm studying on "First Certificate Language Practice, Vince - Heinemann")
(Additional question: Is 'casual clothes' singular or plural?)
