Are you a man or a mouse? When people ask this question they want to know       you think you are a         person or a coward (懦夫). But you will never really know the answer to this question         you are tested in real life. Some people        they are brave but when they come face to face with real       , they act like cowards. Others think of themselves as cowards, but when they meet danger, they act like       .
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.
