1. The other day (I came across) an old photograph of my sister.
2) It's (a waste of time) going to Pete's house - he won't be in.
3) There was (no sign of) the car.
4) It's very noisy - what's (going on) in here?
5) I never (found out) who had written the book.
6) Mrs Stevens (made her way) up the path to the front door of the house.
