He also imagines he was a famous football player. After the next few days, Gardner’s speech became so slurred(不清楚)that people couldn’t understand him. He also had trouble remembering things. By the eleventh day, Gardner couldn’t pass a counting test. In the middle of the test he simply stopped. He couldn’t remember what he was doing.
