a look. Oh, dear!  3  did we see? There   4   a donkey (驴) in the middle of the road. It would not move.
The cars and buses could not get past.
    Then a policeman came."  5   donkey is this?" he asked. "It's mine," said a farmer, "but I  6   move it."
The policeman and the farmer did   7   best to move the donkey, but it would not move. We laughed,
but the   8   of the cars and the buses were worried. "We can't move the donkey," the farmer and the
policeman said. "What shall we do?"
   "Give a carrot   9   him," my father said.
   "What a good idea!" said the farmer.
Soon he found a carrot and showed it to the donkey. When the donkey saw a carrot, it jumped up
and walked after the farmer.   10   the cars and buses could get past at last. How interesting!
