1近年来中国遭受严重的沙尘暴袭击，而中国也被认为是沙尘暴的来源之一。但中国经过努力在治沙尘方面取得了显著的效果。“Most of the sandstorms that swept China last year came from foreign lands” ，a Chinese official in charge of desertification control said on Monday.And the invasion could partly explain the frequent sandstorms in the country in recent years despite its achievements in desertification control.Since the start of last spring，the northern and northwestern Chinese regions had been hit by 17 sandstorms: of which a dozen came from foreign lands.Situated in the central Asia sandstorm region，one of the world's four largest sandstorm sources，China alsosuffers from sandstorms from the outside country while it is also blamed as a sand source to northeast Asia.The other three major sources are in Africa，North America and Australia.The land suffering from desertification has been decreasing by 7，585 square kilometres annually in China，and the area of sandy land has also been falling by 1，284 square kilometres a year.The shrinkage forms a clear contrast to the fact that the land suffering from desertification and the sandy feature was added by 10，400 square kilometers and 3，436 square kilometers late last century.At present，the desertification land in China makes up 2.64 million square kilometers，accounting for 27.46 percent of the nation's land，and its sandy land totals 1.74 million square kilometers，accounting for 18.1 percent of the country's 2total.阅读障碍词1invasion n入侵2despite prep.尽管3blame v谴责4annually adv.一年一度地5shrinkage n收缩6contrast n对比诱思导读阅读短文，回答下列问题。1What are the world's four

this problem and in China，a mass campaign has been started to help solve it.亚洲的沙尘暴数个世纪以来，对很多亚洲国家来说沙尘暴一直是一个大灾难。科学家们尝试过很多办法解决这个问题，在中国，也发动了群众运动来对付沙尘暴。助读讲解 and 为并列连词，句中的 to solve this problem 和 to help solve it 为不定式作目的状语。Sandstorms are strong，dry winds that carry sand.They are often so thick that you cannot see the sun，and the wind is sometimes strong enough to move sand dunes (沙丘)The four main places in the world where there are sandstorms are Central Asia，North America，Central Africa and Australia.Ren Jianbo，from Inner Mongolia described a terrible sandstorm he experienced as a child in the desert.“To have been caught in a sandstorm was a terrible experience， ” he 4said.“There was nothing to be done.It was the most frightening and the most dangerous situation I've ever been in.You just had to hope you'd survive.I thought I was going to disappear under the sand.”沙尘暴是很强的携带沙子的干风。沙尘暴常常很浓密，以至于遮住了太阳，有时风力大的足以移动沙丘。世界上沙尘暴发生的四个主要地区是中亚、北美、非洲中部和澳大利亚。来自内蒙古的任建波描述了他小时候在沙漠里经历过的一次可怕的沙尘暴。他说：“遭遇沙尘暴是一次很可怕的经历。你什么也干不了。那是我遭遇过的最可怕、最危险的境况。你只希望你能幸存下来。我以为我将会被沙子淹没。 ”助读讲解 此处是 so .that .引导的结果状语从句。where there are sandstorms 为 where 引导的定语从句，修饰先行词 The four main places，where在从句中作地点状语。he experienced as a child in the desert 为省略引导词that/which 的定语从句，修饰先行词 a terrible sandstorm。Northwest China is part of the sandstorm centre in Central Asia.Sandstorms begin in desert areas.Sandstorms in China appear to have increased in recent years as a result of“desertification”(沙漠化)This is a process that happens when land becomes desert because of climate changes and because people cut down trees and dig up grass.中国的西北部是中亚地区沙尘暴中心的一部分。沙尘暴发源于沙漠地区。因“荒漠化”越发严重，中国近年来发生沙尘暴的次数明显增加了。这(沙漠化)是一个由于气候变化和人类砍伐树木、铲除草皮而使陆地变为沙漠的过程。助读讲解 process 后是 that 引导的定语从句，其中还包含一个 when 引导的时间状语从句。Sandstorms sometimes affect Beijing.Citizens wake up to an orange sky and strong winds that cover the city in a thick，brown­yellow dust.The storms sometimes continue all day and traffic moves very slowly because the thick dust makes it difficult to see.沙尘暴有时影响北京。居民醒来时，看到昏黄的天空，狂风夹着黄沙在城里肆虐。暴风有时持续一整天，车辆开得很慢，因为浓浓的尘埃降低了能见度。5助读讲解 that cover .是 that 引导的定语从句，修饰先行词 strong winds。because 引导原因状语从句，其中 it 为形式宾语，to see 为真正宾语。The Chinese Central Weather Station can forecast a sandstorm some weeks before it arrives in Beijing，but the strength of the storm sometimes surprises people.When a sandstorm arrives in the city，weather experts advise people not to go out.Huang Xiaomei，who lives in Beijing says， “To be cycling in a sandstorm is frightening.The winds are very strong.It's difficult to breathe and the dust makes me ill. So if you want to go out，you'd better wear a mask.”中国中央气象台能在沙尘暴到达北京几周前进行预报，但风力大得有时让人们吃惊。当沙尘暴到达这座城市时，气象专家建议人们不要外出。生活在北京的黄小梅说：“在沙尘暴中骑车真可怕。风力很大，呼吸困难，并且沙尘使人难受。所以如果你想出门，最好戴上口罩。 ” 助读讲解 and 连接两个并列分句，第一个分句中 it 为形式主语，to breathe 为真正的主语；第二个分句为“主语谓语宾语宾补”形式。The desert is only 250 kilometres away to the west of Beijing.To prevent it coming nearer，the government is planting trees.Already the government has planted more than 30 billion trees and plans to continue planting for the next five years.沙漠位于距北京西部仅 250 公里处。为阻止沙漠的逼近，政府正在植树。政府已经种了 300 多亿棵树，并计划在未来的 5 年里要继续种植。助读讲解 To prevent it coming nearer 为不定式短语作目的状语。第一步 速读了解文章主题和段落大意速读 P32教材课文，匹配段落大意1Para.1 ASandstorms sometimes affect Beijing.2Para.2 BSandstorms do a lot of damage to people.3Para.3 CThe government plants trees to prevent sandstorms.64Para.4 DSandstorms have been a majordisaster for many Asian countries for centuries.5Para.5 ESandstorms in Asia.6Para.6 FSandstorms in China appear to haveincreased as a result of “desertification” 【答案】 16 DEFABC第二步 细读把控文章关键信息细读 P32教材课文，选择最佳答案1What is the best description about a sandstorm according to the passage?AIt is a major disaster for many Asian countries for centuries.BIt's strong wind carrying sand.CIt is a way to cause land to become desert.DIt's a kind of natural disaster that can't be treated.2What is the main reason for the increase of sandstorm in China recently?ATo be close to many deserts.BThe worsening of the weather in China.CThe result of desertification.DPeople cutting down trees and digging up grass.3What is the good suggestion when people meet sandstorm?ANot going out.BIf you go out，just wear thick clothes.CWhen going out，wear a mask.DNever go out，just stay at home.4What is the best way to avoid the effects from the sandstorm?ALiving far away from deserts.BStaying at home when a sandstorm happens.CWearing a mask if you want to go out.DPlanting more trees.7【答案】 14 BCCD第三步 研读能力升华 接轨高考根据 P32教材课文，在空白处填入 1 个适当的单词或括号内单词的正确形式Sandstorms 1.have been (be) a major disaster for many Asian countries for centuries.Scientists have tried many 2.ways(way) to solve this problem.When 3.happening(happen)，sandstorms are so strong 4.that you can see nothing.There is nothing to be done.Sandstorms appear 5.to have increased(increase) as a result of “desertification”，6.which is a process that happens when land becomes desert because of climate changes and because people cut down trees.Sandstorms affecting Beijing，traffic moves 7.slowly(slow) because the thick dust makes 8.it difficult to see.When a sandstorm arrives，experts advise people not to go out.To be cycling in a sandstorm is 9.frightening(frighten)The winds are strong.If you want to go out，you'd better wear a mask.The desert is only 250 kilometres away to the west of Beijing.To prevent it 10.coming(come) nearer，we are planting many trees.
