Passage Two

There was a big pile of bricks on the top of a tall building and a man

had to bring them down to the ground. He had a long rope which went over a pulley(滑轮) at the roof of the building. The other end was fastened to a big box.

First he pulled the box up to the top of the building, and fastened the end of the rope so that the

box could not come down. Then he climbed up the ladder and filled the box with bricks. Next

he climbed down the ladder and untied the rope. Unfortunately the box of bricks was heavier than

the man, and as a result he was pulled up by the: rope. Half-way up, the box of bricks hit him as it was coming down.

When he reached the top, his head hit the pulley. The box of bricks hit the ground and broke.

As a result the bricks fell out. The box was then lighter than the man and consequently he began

to come down and the box began to go up.

Half-way up, the box hit the man. The man still held on to the rope and the box therefore Continued to

go up. The man then reached the ground. Then he let go the rope to rub his head. The box, of

course, then fell down and hit the man on the head again. As a result, an ambulance came and took

him to hospital
