答案                                 Windbreaks
    Farmers use different kinds of soil conservation methods to protect their land against damage from farming and the forces of nature./ One important form of soil conservation is the use of windbreaks. /
    Windbreaks are barriers 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. /
    Windbreaks can help protect a farmer’s land./ However, / windbreaks seem to work best when they allow a little wind to pass through. / If the wall of trees and plants blocks the wind completely, / then violent air motions will take place close to the ground. / Theses motions cause the soil to lift up into the air where it will be blown away. /
