One day, I was working alone on the roof of a new six-story building. When I pleted my work, I discovered that I had about 500 pounds of bircks left over!   36 carry the bricks down by hand I decided to lower them by a pulley（滑车）, which fortunately was  _37 to the side of the building on the sixth floor.
Fastening the rope at the ground level, I went up to the roof and  _38 the bricks into a barrel (桶). Then I went back to the  _39 and untied the rope,   40 it tightly to insure a     41      fall of the 500 punds of bricks. You know, I only weighed 135 pounds. Due to my     42 _ at being pulled off the ground so suddenly, I lost my presence of mind and  _43  to let go of the rope. Needless to say, I went on at a rather  _44 _ rate up the building.

Also near the  _50 _ floor, I met the barrel ing up, which made my legs broken. The encounter（相遇）with the _ 51 _ slowed me enough to reduce my  _52 when I fell onto the pile of bricks, and  53 , only three vertebrae（椎骨）were broken. However, as I     54    there on the bricks in pain, unable to move, and  _55  the barrel six stories above, I again lost my presence of mind. I let go of the rope!
