Practice 1  Directions: Read the texts from a newspaper article in which five people talk about where they played when they were children. For questions 1 to 5, match the name of each people (1 to 5) to one of the statements (A to G) given below. Mark your answers on ANSWER SHEET 1.  Peter:  My favorite childhood play area was the back garden. Back in the days when I was growing up on a large housing estate, the ‘goals’ would be a pair of garage doors or two jackets laid out in the garden. I would spend hours kicking a ball about with my dad, learning how to control, dribble or kick it.  Simon:  The playground was quite small The floor was covered with flat bricks and there were many that were cracked or broken or missing, and a few weeds struggled through. It was totally enclosed on one side by the school and on the other by high brick walls. It was more like a prison yard--on top of the walls was a layer of concrete into which pieces of broken glass had been stuck. After school was finished my friends and I would climb a lamppost outside the school and sit on top of the wall, slowly breaking off the bits of glass.  Alan:  I come from an area of terraced houses, pavements and streets. There were no gardens. My first school was Prince’s Street Primary and the room in which I received my first lessons had large, folding glass doors that opened onto a small playground that had grass, bushes and flowers. My amazement at seeing these items, which are normal to most of the world, has stayed with me all my life.  Nick:  I was strictly forbidden from the obvious playground--a long, overgrown ditch running through waste ground, mainly built to take away the rain. It was irresistible to us local schoolchildren. Its charm, compared with the surrounding tennis courts, football pitches and farmland, was purely because it was out of bounds. That area was truly where I grew up, more than in the rest of the little town’s correct and neat suburbia, where my house was.  Julle:  Unitl I was twelve I was brought up on airforce camps and each camp had a small playground in the middle of the houses. It was always a great meeting place and I remember sitting with my friends on the swings many evenings until dark. You would often go out and swing for hours until someone else came out. I always liked swinging.  Now match each of the people (1 to 5) to the appropriate statement.  Note: there are two extra statements.  Statements
