Lenny had always thought of himself as a　 27　 person. He got worried before examinations. He worried about his job and health. All he wanted in life was to be safe and healthy.　 28 , on January 15th, 2002, a plane crashed into the Potomac River in Washington. Lenny went to the river to see what was happening.

When you are in a very　 34　 situation and feel afraid, the body automatically produces a chemical in the blood. The chemical is called adrenalin.　 35　 adrenalin in the blood system, you actually feel stronger and stronger and are　 36　 to fight or run away. However, when you are absolutely terrified, the body can produce too much adrenalin. When this　 37 , the muscles become very hard and you find you　 38　 at all. You are then paralyzed (使无能为力) with fear. This is　 39 when we are very frightened, we sometimes say we’re “petrified”. This word comes from the Greek word “petros”, which means “stone”. We are　 40　 frightened that we become stonelike.
