A strange story
When I was 7 years old, my family left the big city and moved to the countryside. I was very excited because our new house was near a beautiful forest.
One day I decided to go for a walk in the forest but I lost my way. I tried to get back but I just went deeper into the forest. I looked around me and started calling for help, but no one heard me. I was confused and scared because it was almost dark, so I sat under a tree and began to cry.
Suddenly I heard someone coming. It was a boy of my age. “Hi”, he said. “I’m Philip. What’s the matter?” I told him that I was lost. “Don’t worry”, Philip said. “I live near here. I know the forest well”. We walked and talked until we were out of the forest. Philip said goodbye and left before I could thank him.
When I got home my mum was talking to a policeman. They were both very upset. “Oh, Tom, thank goodness you’re OK!” my mum said when she saw me. “I lost my way in the forest, mum, but I’m fine now. I’m so sorry”, I said. “You were lucky, young man”, the policeman said. “Never play alone in that forest, it’s too dangerous. 8 years ago, a boy named Philip Mac Mann lost his way in that same forest and never came back”.
I didn’t say a word. I wanted to tell them about the boy who helped me but I was afraid they wouldn’t believe me. Did a ghost help me? I couldn’t sleep that night, or the next. I never saw Philip again and I never went back to the forest!

39. Where did Tom’s family move to?
40. How did Tom feel when he discovered he was lost?
41. Did Tom thank Philip when they were out of the forest?
42. What happened to Philip Mac Mann 8 years ago?
43. Why couldn’t Tom sleep that night?
