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 e face to face with real     , they act like cowards.

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 pletely afraid), the body can produce too much adrenalin. When this     , the muscles bee 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 es from the Greek word “petros”, which means “stone”. We are     frightened that we bee stonelike.
