First, I would like you to look at these two sentences:
'I used scissors to cut it.'
'I wore glasses to read a book.'
And I am going to form passive sentences from the two.
'Scissors were used to cut it(this makes sense, right?)
'Glasses were worn to read a book'(this.. doesn't make sense to me at all.. I don't know why)
Does the second sentence make sense to you? Why doesn't the second sentence make sense to me?
