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.

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!
