六、任务型阅读。
阅读短文，回答下列问题。
On a farm live a father and a son. The father always gets up early and reads books outside the house. One morning, the son comes up to his father and says, “Dad, I read books at night but forget most of them the next morning. What's the good of reading?”
The father doesn't answer the question. He gives his son a basket that is used to carry coal (运煤). He says, “Get some water from the river with the basket and then I'll tell you the answer.”
The son feels surprised, but he does as his father says. He tries many times but every time the water leaks(漏) from the basket.
An hour later, the son comes back with nothing and tells his father it is hard to get water with the basket. The father says 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 finds the dirty basket becomes clean. The father says, “Reading is like carrying water with the basket. Although we can't remember all we read, we have changed when we read.”
