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 to 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.【语篇解读】保护土壤的一个办法就是使用防风林，防风林是由树木和其他作物组成的障碍物。农民在农田周围种上这些障碍物，有利于增加农业收成。1The advantages of building a windbreak are as follows except _.Akeeping the wind from destroying grain cropsBincreasing the grain harvestsCproviding humans with shade from the sunDreducing the damaging effects of wind and rain答案与解析：C细节理解题。根据文章第一段中的“They also keep the wind from damaging or destroying crops”可排除A项；根据文章第二段内容可排除B项；根据文章第四段中的“Trees reduce the damaging effects of wind and rain”可排除D项，故选C。2The author thinks windbreaks are interesting because _.Athe movement of air lifts the soilBwindbreaks work best when they allow some wind to pass throughClarge trees are lined with shorter onesDwindbreaks can stop the wind getting through答案与解析：B细节理解题。根据文章第三段中的“They seem to work best when they allow some wind to pass through the barrier of trees or plants around a field”可知，当有风可以通过时防风林效果最好，故选B。3If the trees grow to a height of 30 feet, the areas the windbreak can protect are _.A100 square feet B150 square feetC240 square feet D300 square feet答案与解析：D细节理解题。根据文章第三段中的“An easy rule to remember is that windbreaks can protect areas up to 10 times the height of the tallest trees in the windbreak”可知防风林可以保护的面积是防风林中最高的树高度的10倍，故选D。4What can be inferred from the text?AExtra trees and plants can be cut down for wood.BThe environment is going from bad to worse.CTrees and plants from abroad are the best for windbreaks.DWindbreaks can contribute to agricultural harvests.答案与解析：D推理判断题。根据文章第二段中的“For example, in parts of West Africa grain harvests were as much as twenty percent higher in fields protected by windbreaks compared to fields without them”可知种植防风林有利于农业丰收，故选D。.完形填空My aunt came to my home with her sixyearold daughter Alice this morning.
