语篇提能.阅读理解soil conservation(保护) efforts protect soil from wind and water that can blow or wash it away. good soil produces good crops for both humans and animals.one important form of soil conservation is the use of windbreaks. windbreaks stop the wind from blowing soil away. they also keep the wind from destroying or damaging crops. windbreaks are barriers(屏障) formed by trees and other plants with many leaves. farmers plant windbreaks in lines around their fields. they are very important when grains such as wheat are grown. windbreaks are effective(有效的) when a wall of trees and other plants blocks the wind. the windbreaks should also limit violent motions of the wind to those areas closest to the windbreaks.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 cause the soil to lift up into the air where it will be blown away. for this reason，a windbreak is the best if it has only 60 to 80 percent of the trees and plants needed to make a solid line. an easy rule to remember is that windbreaks can protect areas up to ten 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 formed from shorter trees and other plants with leaves. windbreaks not only protect land and crops from the wind. they can also provide(提供) wood products. these include wood for fuel and longer pieces for making fences(栅栏). locallygrown trees and plants are best for windbreaks.1why should windbreaks allow a little wind to pass through?aso as to prevent violent air motions taking place.bso that the crops can breathe enough fresh air.cso as to save a lot of money by planting fewer trees.dbecause a little wind helps the crops grow better.2a 10metrehigh windbreak can protect crops as far as _ metres away.a6080 b. 100c10 d. 503what does the word “windbreaks” underlined in the second paragraph mean?a森林 b大森林 c防风林 d护风林4the passage is mainly about _.asoil conservationbcrops and soil conservationcwindbreaksdtrees and crops答案与解析：1解析：细节理解题。根据文章第三段“if the wall of trees and plants stops wind completely，then violent air motions will take place close to the ground.these motions cause the soil to lift up into the air where it will be blown away.”可知，防风林要允许进点风的目的是不至于使土地上升到被吹走。答案：a2解析：推理判断题。根据文章第三段第五句“an easy rule to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreak.”可推算出一个10米高的防风林最多能保护远于它10倍的庄稼。答案：b3解析：词义猜测题。实际上该画线单词windbreaks后给出了解释“windbreaks stop the wind from blowing soil away.they also keep the wind from destroying or damaging crops.”，所以可猜测是防风林。答案：c4解析：主旨大意题。文章始终提及核心单词windbreaks及它的作用和人们如何种植，我们可知本文主要写的是防风林(windbreaks)。答案：c.完形填空it was mothers day and i was shopping at the local supermarket with my fiveyearold son, tenyson. as we were _1_， we realized that only minutes earlier an _2_ woman had fallen over at the entrance and hit her head on the ground. _3_ was with her, but there was blood everywhere and the woman was embarrassed and clearly in shock. _4_ a lot of people stopped to help out._5_ we were walking towards the scene, tenyson became very _6_ about what had happened to the elderly couple. he _7_ to me, “mom, its not much fun falling over in front of _8_.” seeing that there was a flower stall(摊位)at the front of the supermarket, he added, “why shouldnt we _9_ the lady a flower?
