Every morning Grandpa got up early sitting at the table, reading his book. His grandson wanted to be just like him and tried to copy him in every way he could.

One day the grandson asked, “Grandpa, I try to read the book just like you, but I don’t understand it, and I forget what I understand as soon as I close the book. What good does reading the book do?” The grandpa quietly turned from putting coal 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 he was told, but all the water leaked out before he got back to the house. The grandpa laughed and said, “You’ll have to move a little faster next time,” and sent him back to the river with the basket to try again.

This time the boy ran faster, but again the basket was empty before he returned. Out of breath, he told his grandpa that it was impossible to carry water in a basket, so he went to get a bucket instead.The grandpa said, “I don’t want a bucket of water; I want a basket of water. You’re just not trying hard enough.”

The boy again dipped the basket into the river and ran hard, but when he reached his grandpa the basket was empty again. Out of breath, he said, “Grandpa, it’s useless !”“So, you think it is useless?” the grandpa said, “Look at the basket.”

The boy looked at the basket and for the first time he realized that the basket was different. It had been transformed from a dirty old coal basket and was now clean.

“Grandson, that’s what happens when you read the book. You might not understand or remember everything, but when you read it, you’ll be changed, inside and out.”

Windbreaks are barriers(屏障)formed by trees and other plants.Farmers plant these barriers around their fields,which help prevent the loss of soil,and stop the wind from blowing soil away.They also keep the wind from damaging or destroying crops.Besides,extra trees and plants can be cut down and used or sold for wood.

Windbreaks can be highly valuable for protecting grain crops.For example,in parts of West Africa grain harvests were as much as twenty percent higher in fields protected by windbreaks compared with fields without them.

But here is something interesting about windbreaks.They seem to work best when they allow some wind to pass through the barrier of trees or plants around a field.If not,then the movement of air close to the ground will lift the soil.Then the soil will be blown away.For this reason,a windbreak works best if it contains only 60 to 80 percent of the trees and plants that would be needed to make a solid line.An easy rule to remember is that windbreaks can protect areas up to 10 times the height of the tallest trees in the windbreak.

There should be at least two lines in each windbreak.One line should be large trees.The second line,right next to it,can be shorter trees or other plants with leaves.Locally grown trees and plants are considered the best choices for windbreaks.Trees reduce the damaging effects of wind and rain.Their roots help protect soil from being washed away.And trees can provide animals outdoors with shade from the sun.
