13. On a farm lived a father and son. The father always got up early and read books outside the house. One morning, the son came up to his father and said, "Dad, I read books at night but forgot most of them the next morning. What's the good of reading?"
The father didn't answer the question. He gave his son basket(筐)that was used to carry coal(运煤). He said, "Get some water from the river with the basket and then I'll tell you the answer(答案). "
The son felt surprised but he did as his father said. He tried many times but every time the water leaked(漏)from the basket.
An hour later, the son came back with nothing and told his father it was hard to get water with the basket. The father said with a smile, "Yes, you are right, my son. The basket can't carry water. But can you see the basket is different?" The son then found the dirty basket became clean. The father said, "Reading is like carrying water with the basket. Although we can't remember all we read, we have change(改变)when we read. "
