题目内容
1.Villagers of the high desert of Ladakh in India's Jammu and Kashmir state used to harvest plentiful crops of wheat,fruits,and vegetables in summer.But for years the streams have run dry in spring,just when farmers needed water to sow seeds.They had water when it wasn't needed during the rest of the year,such as in winter,when people let water run from taps to prevent pipes from freezing and bursting.Villagers blame climate change for causing glaciers (冰川) to shrink by melting them faster than before.To solve the water-shortage problem,Sonam Wangchuk,a mechanical engineer,and his team of volunteers are building a huge vertical block of ice in Phyang,nine miles from Leh,the capital of Ladakh.When spring comes and the artificial glacier melts,farmers will have flowing water.This method stores water without the need for concrete water storage tanks or dam.While it won't stop glaciers from shrinking,it could help people adapt to a warming world.
Last winter,Wangchuk built a six-meter-high prototype on am open riverbank totest his novel idea.It stored 150,000liters of water at 3,170meters,the lowest altitude in Leh valley.This,he said,proved ice pyramids (金字塔)can be built anywhere in the region.When the prototype lasted until mid-May,he was encouraged to attempt a 30-metre-high pyramid of ice this winter.But the cost of piping water from the Phyang stream,1.5miles away,was a huge S 100,000.Not discouraged,he somehow raised the money and work began on 21January.
The site was waterproofed with clay (粘土),so when the ice pyramid melted,water would not get into the desert sand.Sprinklers (喷淋装置)sprayed water from above,and the cold wind froze the tiny drops of water as they hit the ground.A cone of ice built up slowly but steadily.With only two more weeks of winter left,time is running short.The pyramid will likely be no more than 15meters high when completed,half the size of the planned 30meters.
"This year was the first time,so there were complications and delays,Wangchuk said."We wanted to achieve two things--to show how to make an ice pyramid and how to green a patch of desert."It's difficult to say how many people will eventually benefit;Fhyang village has only 2,000people.But there'll he enough water for many more.This is an economic as well as ecological activity."
In the coming years,Wangehuk hopes to build 80to 90ice pyramids,each more than 30meters tall,in Phyang village.They'll store 1bn liters of water,enough to irrigate 600hectares ( 1,500acres) of desert,he says.To make so many ice pyramids,the only additional investment is the pipeline.Wangehuk said:"We need more pipes so we can extend it farther and farther.It will take another $ 100,000to make the other ice pyramids."Once the pipes are laid,frozen ice pyramids can be built year after year without pumping in more money.The underground pipes will last a hundred years.But for now,the desert around the 3,500-metre-high Phyang will turn green in summer,as water flows for the first time in many years.

A.the ice pyramid can't store enough water
B.it is quite expensive to lay the pipes
C.the ice pyramid can't be built high enough

分析 这是新闻报道类文章阅读.该文章主要介绍了Wangchuk's带领村民们采取建冰金字塔的方式储存冰水,用于农田灌溉的经过以及该设备的优势和不足.
解答 41-45 CABDA
41.C.细节理解题.通读前两段可知这主要是为了提供背景资料.故选C.
42.A.词意猜测题.通读第三段,并根据关键词pyramid,piping water,attempt等可知这种设置是复制了古埃及的金字塔,故选A.
43.B.细节理解题.根据文章第三段的But the cost of piping water from the Phyang stream,1.5miles away,was a huge$100,000可知这种金字塔放管子很贵的.故选B.
44.D.细节理解题.根据文章第二段的This method stores water without the need for concrete water storage tanks or dams可知这种设备就不用再建混凝土的大坝.故选D.
45.A.文章出处题.通读全文,该文章主要介绍了Wangchuk's带领村民们采取建冰金字塔的方式储存冰水,用于农田灌溉的经过和该设备的优势和不足.由此可推断应是源于一家报纸.故选A.
点评 本文为政治经济类阅读文章,该类文章时代气息浓郁,语言鲜活,但熟字新义词、超纲词及专业词语多,长句、难句多.政治类文章大多数是同学们感性趣的内容,读起来倒有似曾相识的感觉,阅读这类文章,要抓住文章的核心,即文章整体和各段主要在说什么,也要注意段落之间的逻辑关系.
