Lenny had always thought of himself as a         person. He got worried before examinations. He worried about his job and health. All he wanted in life was to be safe and healthy.         , on January 15th, 2002, a plane crashed into the Potomac River in Washington. Lenny went to the river to see what was happening. He saw a woman in the         water. Lenny did not feel afraid. He kept very           and did a very dangerous thing. He jumped into the river,          to the woman, and kept her head          the water. Seventy-eight people died that day. Thanks to Lenny, it was not           .
When you are in a very        situation and feel afraid, the body automatically produces a chemical in the blood. The chemical is called adrenalin (肾上腺素).        adrenalin in the blood system, you actually feel stronger and stronger and are        to fight or run away. However, when you are absolutely terrified (or completely afraid), the body can produce too much adrenalin. When this       , the muscles become very hard and you find you       go at all. You are then paralyzed (使无能为力) with fear. This is        when we are very frightened, we sometimes say we’re “petrified”. This word comes from the Greek word “petros”, which means “stone”. We are       frightened that we become stonelike.
