farmer put his son  3    the ass.

     Further down the road, they passed some old people who scolded the farmer for allowing his young

son to ride    4  said that he should be riding himself .

     Further along the road, they passed some travelers who said that if he wanted to sell the ass the two

of  them should carry him   5   the ass would be exhausted and worthless. So the farmer and his son

bound the ass's legs to a pole and carried him. 

    When they approached the town, people there laughed at the sight of them. The noise was so loud 

   6        the ass was frightened to   7   (die). He kicked out and    8    (fall) off a bridge into the river

and drowned.
