1、2013年高考第二轮复习英语陕西版专题升级训练十六史地、自然、科普、新闻类阅读理解、信息匹配(一)第一节阅读理解AThe Alps are the youngest and highest mountain system in Europe.They stretch across the western and southern part of the continent in a broad arc.The mountain range starts near the Mediterranean Sea on the border between France and Italy.Then
2、it curves north and eastward through northern Italy,Switzerland,Liechtenstein,southern Germany,Austria and Slovenia.The Alps are about 1,000 km long,and the broadest section is over 260 km wide.The highest peak,Mont Blanc,situated on the border between France,Italy and Switzerland,rises 4,807 meters
3、 above sea level.Other famous peaks are the Monte Rosa,the Matterhorn,the GroBglockner and the Zugspitze.Millions of years ago the area of todays Alps was covered by a large sea that separated Europe and Africa.The southern land mass started moving northwards.This movement folded rock layers at the
4、bottom of the sea.Heat and pressure transformed the rock and pushed the_material upwards.Today these regions are the highest parts of the Alps.Most of the newly formed rock is granite and gneiss,but many ranges consist of limestone which also formed on the seabed.During the Ice Age,which started abo
5、ut a million years ago,the Alps were covered with a thick blanket of snow.Glaciers moved down valleys and made them wider and deeper.As they moved they took rock and other material with them,creating moraines(冰碛)When glaciers started to melt water filled up behind these natural dams and created the
6、alpine lakes we know today.The largest of these glaciers is the Aletsch in Switzerland which reaches a length of about 25 km.The longest glacier of the eastern Alps is the 8 km long Pasterze,at the foot of the GroBglockner.The ice and snow of the alpine regions helped create the large rivers of toda
7、y:the Rhine,Rhone,Danube and the Po.1From the first two paragraphs we know the Alps _.Aare about 260 km wideBstretch across the western part of AfricaCare the youngest mountain system in the worldDhave the highest peak 4,807 meters above sea level2What does the underlined phrase “this material” in P
8、ara.3 refer to?ASea water and rock.BRock that was transformed.CRock layers that were folded.DLimestone which was on the seabed.3It can be inferred from the passage that the Alps were formed _.Abefore the Ice AgeBduring the Ice AgeCbecause of seas movement Dbecause of glaciers movement4From the passa
9、ge we know Danube is _.Aa kind of rock Bone of the Alps famous peaksCthe name of a river Done of the largest glaciersBNanoparticles(纳米粒子)are everywhere,from cosmetics and clothes,to soda and snacks.But as common as they are,they also have a downside,say researchers at Binghamton University and Corne
10、ll University in a recent paper published in the journal Nature Nanotechnology.These tiny particles,even in low doses,could have a big impact on our longterm health.According to the lead author of the article,Gretchen Mahler,assistant professor of bioengineering at Binghamton University,much of the
11、existing research on the safety of nanoparticles has been directly related to health effects.But what Mahler and a team of researchers really wanted to know was what happens when someone gets constant exposure in small dosesthe kind youd get if you took a drug or supplement that included nanoparticl
12、es in some form.“We thought that the best way to measure the more subtle(精细的)effects of this kind of intake was to monitor the reaction of intestinal(肠道的)cells,”said Mahler.“And we did this in two ways:through human intestinallining cells that we had cultured in the lab,and through the intestinal li
13、nings of live chickens.Both sets of results pointed to the same thingthat exposure to nanoparticles influences the absorption of nutrients into the bloodstream.”The uptake of iron was of particular interest due to the way it is absorbed and processed through the intestines.“What we found was that fo
14、r brief exposures,iron absorption dropped by about 50 percent,”said Mahler.“But when we extended that period of time,absorption actually increased by about 200 percent.It was very clearnanoparticles definitely affect iron uptake and transport.”While brief oral exposure disrupted intestinal iron tran
15、sport,longtime exposure caused intestinal cells to be larger and broader,thus allowing iron to enter the bloodstream much faster.“The intestinal cells are a gateway that ingested nanoparticles must go through to get to the body,”said Mahler.“We monitored iron absorption and found that the polystyren
16、e nanoparticles affected the absorption process and caused a physiological response.”5What is the best title for the passage?ANanoparticles are common in our life.BNanoparticles have an effect on our health.CWe should know more about nanoparticles.DThe intake of nanoparticles should be banned.6Gretc
17、hen Mahlers research is to _.Ameasure the direct health effects of iron uptakeBfind out the effect of longtime exposure to nanoparticlesCexplore how to reduce the effects of nanoparticlesDstudy how nanoparticles affect chickens7The underlined word “disrupted” in the last paragraph probably means “_”
18、AdisorderedBbenefitedCdiscovered Dfollowed8In which part of a magazine can this passage most likely be found?AScience. BHistory.CEntertainment. DEconomy.CClimate change is threatening to redraw the worlds wineproducing map,and the effects are already being seen in earlier harvests and coarser(更为粗糙、劣
19、质的)wines.“The consequences of global warming are already being felt.Harvests are already coming 10 days earlier than before in almost all grapegrowing regions,”said Bernard Seguin,the head of climate studies at Frances INRA agricultural research institute.He was speaking at the opening of the Second
20、 International Congress on Wine and Climate Change.“Wine and wineproducing will change in a way that will depend on how we face global warming,”said Seguin.“If the temperature rises two or three degrees centigrade,we could manage to see Bordeaux remain as Bordeaux,Rioja as Rioja,Burgundy as Burgundy
21、.But if it goes up five or six degrees,we must face up to huge problems,and the changes will be hard,”he said.Grapes are damaged if they ripen too quickly,due to higher temperatures and a lack of rain.“When a grape matures more quickly,you get higher concentrations of sugar,lower acidity(酸性)and a hi
22、gher PH level,”said Fernando Zamora of the oenology faculty(葡萄酒酿造学系)at the University of Tarragona in Spain.The result is coarser wines,with a higher alcohol level and lower acidity which can destroy the delicate flavor of good quality wines,he said.It would also lead to higher prices in countries w
23、hich tax wine according to its alcohol level.“The types of wines will change in almost all regions,”said Vicente Sotes,a professor at the Polytechnic University.And some regions which still produce good wine would no longer benefit from the ideal climatic conditions that are responsible for their fa
