Different kinds of soil conservation methods are used by farmers to protect their land from damage by farming and the forces of nature. One important form of soil conservation is the use of windbreaks.

Windbreaks are barriers (屏障) formed by trees and other plants with many leaves. Farmers plant them in lines around their fields. Windbreaks stop the wind from blowing soil away. They also keep the wind from destroying or damaging crops. They are very important for growing grains, such as wheat.

There have been studies done on windbreaks in parts of West Africa, for example. They found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection.

However, windbreaks seem to work best when they allow a little wind to pass through. If the wall of trees and plants stops wind completely, then violent air motions will take place close to the ground. These motions will lift soil into the air where it will be blown away. For this reason, a windbreak is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line.

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 and other plants with leaves. Locally grown trees and plants are best for windbreaks.

1.What is a windbreak according to the passage?

A. A windbreak is a concrete wall to prevent the strong winds.

B. A windbreak is a wood with different kinds of trees.

C. A windbreak is a wall of trees to hold soil in place.

D. A windbreak is a wall of wind to fight wind from the opposite way.

2.When can windbreaks be most effective?

A. The trees are planted one by one.

B. The trees and plants grow in a line.

C. The trees grow as high as they can.

D. Windbreaks allow a little wind to blow through.

3.Which of the following statements is NOT true?

A. A windbreak is one of the best forms of soil conversation.

B. A windbreak is very good for growing grains such as wheat.

C. One line of trees is enough for soil protection.

D. Locally grown trees and plants are the top choice for a windbreak.

The ninth week of SEAL(Sea, Air, Land) training is referred to as Hell Week. It is six days of no sleep, physical and mental suffering and one special day at the Mud Flats (泥沼）where you will sink into the mud.

It is on Wednesday of Hell Week that we came down to the mud flats and spend the next 15 hours trying to survive the freezing-cold mud, the cold wind and the strong pressure from the instructors to give up.

As the sun began to set that Wednesday evening, my training class, having broken some of the rules, was ordered into the mud. We sank into the mud until only our heads could be seen. The instructors told us we could leave the mud if only five men would give up—just five men and we could get out of the cold.

Looking around the mud flat, it was clear that some of us were about to give up. It was still over eight hours till the sun came up--eight more hours of coldness. Our cries were so loud that it was hard to hear anything. And then, one voice began to fly through the night--one voice raised in song.

The song sounded terrible, but it was sung with great power. One voice became two, and two became three, and before long everyone in the class was singing.

We knew that if one man could rise above the suffering then others could as well. The instructors warned us of more time in the mud if we kept up the singing—but the singing went on and on. And somehow, the mud seemed a little warmer, the wind a little weaker and the morning not so far away.

If I have learned anything in my time traveling the world, it is the power of hope. The power can change the world by giving people hope.

So, if you want to change the world, start singing when you're up to your neck in mud.
