I have to think about school first _11_ (of, in, at) all because my parents wouldnt let me work if my grades suffered, so I only work _12_ (on, in, at) holidays. Last year I had a five-year-old to look _13_ (for, after, at) three times _14_ (in, _, on) a week. I had to feed her and then put her _15_ (in, to, on) bed. She was all right; a bit difficult _16_ (at, in, for) times, but I liked to play with her and tell _17_ (-, to, with) her stories. This term I work _18_ (on, in, for) Saturday afternoons as well. It doesnt pay too well, but I am too young to do any other job. I do a round of about twenty houses in the neighbourhood _19_ (on, in, with) my bike. I deliver food from the supermarket and leave it _20_ (at, on, to) the front door.
