One day, I was working alone on the roof of a new six-story building. When I completed 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.

At approximately（大约）the same time, the barrel  _47__ the ground, and the bottom fell out of the barrel.   48  the bricks, the barrel now weighed about 50 pounds. I refer you again to my weight of 135 pounds.  _49   you might imagine, I began a rapid down.

Also near the  _50 _ floor, I met the barrel coming 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!
