An old man lived with his little grandson. Every day the old man got up
early to read books. His grandson wanted to be just like him and tried to copy
him in every 1 he
could.
One day the grandson asked, "Grandpa, I want to read books as you
do. But I don't understand it, and I always forget 2 I close the book. What good does 3 do?"
The grandfather quietly turned back from putting 4 in the stove and replied, "Take this coal
basket down to the river and bring me back a basket of water."
The boy did as his grandpa said, but all the water leaked (漏) out before he
got back home.
The grandfather laughed and said, "You'll have to walk faster next
time."
The next time the boy ran faster, but the basket was still empty before
he 5 home.
The boy said, "see, Grandpa, it's 6 to do the work!"
"Is it of no use?" the old man said. "7 the basket."
The boy looked at the basket and for the first time realized that the
basket was 8. Instead of a dirty old coal basket, it
was 9 inside
and out.
"My child, that's what happens when you read the book. You might
not understand or remember everything, but the 10 will change you inside and out. That is the
work of reading in our lives."
