201758. (2024•西安中学•三模) When you think of a map,is north on the top or the bottom?Usually,maps are designed with north on top,though when we think about it,there s no logical reason for this bias.After all,there is no up or down in space.So what's wrong with south,east or west being on the top of the map?The answer is:nothing at all.In fact,north-up maps only became the norm in the last few hundred years.
   Ancient Egyptian maps had south at the top because the Nile River flows downhill from mountains in the south to the Mediterranean Sea in the north.Mecca was to the south of most early Muslim civilizations,and south-up maps were designed so that viewers would look up to see Mecca.Medieval Christian maps had east at the top,as they believed the Garden of Eden was in the east.The only early maps that had north at the top were those of early China because the emperor lived in the north.
   North seems to have settled at the top of maps during the 16th century,largely thanks to a Flemish mapmaker,Mercator.Mercator was a great admirer of an early Greek mapmaker,who,for reasons now unknown,put north at the top of maps,so Mercator did,too.When Mercator's world map became the standard map to navigate the oceans,north up became standard as well.
   What is the implication of this north-view of the world?Psychologically,people tend to think of up as good and down as bad.Just think of words and phrases like "upmarket","upbeat" and "moving up in the world",and how they contrast with their opposites.Because north is so consistently put at the top of maps,people now think of north as good,too.
   Several attempts have been made in recent years by introducing south-up maps to the market.These maps not only give us a chance to see the world differently,but also give everyone the chance to see themselves on top.

(1)What can we learn from the first two paragraphs?        
A.North-up maps were rare in ancient times.
B.Deciding up or down in space is ridiculous.
C.Mecca maps were based on a legend.
D.The south-up map first appeared in ancient Egypt.
(2)Why is north associated with good?        
A.An illogical reason.
B.The spread of Mercator's maps.
C.People's preference for up.
D.An age-old tradition in Greece.
(3)What is the authors attitude to south-up maps?        
A.Cautious.
B.Supportive.
C.Uncaring.
D.Disapproving.
(4)What's the main purpose of the text?        
A.To explain a phenomenon.
B.To compare various facts.
C.To correct a cultural bias.
D.To argue for a viewpoint.

1A.细节理解题。由文章第二段  Ancient Egyptian maps had south at the top because the Nile River flows downhill from mountains in the south to the Mediterranean Sea in the north.Mecca was to the south of most early Muslim civilizationsand southup maps were designed so that viewers would look up to see Mecca.Medieval Christian maps had east at the topas they believed the Garden of Eden was in the east.The only early maps that had north at the top were those of early China because the emperor lived in the north(古埃及地图的顶部是南,因为尼罗河从南部的山脉流向北部的地中海。麦加位于大多数早期穆斯林文明的南部,因此人们设计了向南的地图,这样人们就可以抬头看到麦加。中世纪的基督教地图上有东方,因为他们认为伊甸园在东方。只有早期的中国地图,上面有北方,因为皇帝住在北方。)可知,古代大部分国家的地图的顶部是南或者东方,只有中国将北作为地图的顶部,所以以北为上的地图在古代是很少见的。故选A项。
2C.细节理解题。由文章第四段What is the implication of this northview of the worldPsychologicallypeople tend to think of up as good and down as bad.(这个世界向北的观点意味着什么?心理上,人们倾向于认为向上是好的,向下是坏的。)"可知 ,为什么北方和好有关是因为人们对向上的偏好。故选C项。
3B.推理判断题。由文章最后一段Several attempts have been made in recent years by introducing southup maps to the market.These maps not only give us a chance to see the world differentlybut also give everyone the chance to see themselves on top.近年来,通过将南向地图引入市场,已经进行了几次尝试。这些地图不仅让我们有机会从不同的角度看世界,也让每个人都有机会看到自己处于顶峰。)可知 ,南在上的地图不仅让我们有机会从不同角度看世界,也让每个人有机会看到自己处于顶峰,可以让我们从另一个角度看待世界和自己,所以作者对南在上的地图是支持的,肯定的。故选B项。
4D.推理判断题。由文章最后段Several attempts have been made in recent years by introducing southup maps to the market.These maps not only give us a chance to see the world differentlybut also give everyone the chance to see themselves on top.(近年来,已经进行了几次尝试将南向地图引入市场。这些地图不仅让我们有机会从不同的角度看世界,也让每个人都有机会看到自己处于顶峰。)可知,作者知道现在大多数地图都是北向上的,但是他认为南向上的地图也是有好处的,希望南向上的地图可以让人们从另一个角度看待世界和自己,可推知作者写这篇文章的目的是支持这个观点,南向上的地图可以让我们多一个角度看世界。故选D项。

219307. (2021•鄠邑二中•高一上二月) The Great Wall of China was once thought to have been built entirely during the Qin Dynasty between 221 and 207 BC;it is now believed to have been started earlier.
   The 15-foot-high,25-foot-wide,1500-mile-long structure was undoubtedly built to keep out invading enemies.To the common people of the empire,who had been forced to build the wall,it was not worth it,however.The wall,and other public works completed by the Qin Dynasty,had caused great losses on the wealth and human life of the country.As a result,an angry population rose up in rebellion against the Qin Dynasty,and in 207 BC the Han Dynasty began.
   Because of its rich history and magnificent appearance,the Great Wall attracts many tourists,scientists,and historians to this day and will continue to do so for generations.

(1)According to the author of this passage,the Han Dynasty was able to come into power because        .
A.enemies were not effectively prevented from invading the empire

219292. (2022•铁路中学•高二下二月) Sea life near Turkey is being threatened by a layer of brown foam on the ocean's surface.
   The actual name for the foam is mucilage (黏液).Scientists first noticed and described mucilage in 2007,when it was found near Turkey.Then,it was also found in other parts of the Aegean Sea,near Greece.
   This year's outbreak of mucilage is the worst ever recorded.It's been developing for seven months and is now covering large parts of the Sea of Marmara.The Sea of Marmara is an "inland sea",surrounded by land belonging to Turkey,and connected to the Aegean Sea and the Black Sea.
   There are many different kinds of algae (海藻),and it's natural and normal for algae to grow in the ocean or in other bodies of water.But when there is lots of food for the algae,and other conditions are just right,there can be " an algae bloom " which results in algae growing quickly and in huge numbers.And in very bad situations,mucilage is the result.
   There are two main causes for the present outbreak of mucilage.One is the heavy pollution sewage,fertilizers,and other chemicals-flowing into the Sea of Marmara.The second cause is higher water temperatures because of climate change.
   The mucilage causes problems in lots of different ways.For one thing,by covering the ocean's sur- face,it stops sunlight from reaching all the sea life below. "This mucilage is now covering the sea surface like a tent canvas, " says Muharrem Balci,who teaches biology at Istanbul University.Because there is so much algae,it takes up lots of oxygen from the seawater.That means that there's very little oxygen left for the other sea creatures that depend on it.The BBC reports that divers in the area are seeing large numbers of dying fish.After a while,the mucilage falls to the bottom of the ocean,where it covers the sea floor threatening to poison creatures that live there,like crabs and mussels.This year,the mucilage has been found as deep as 30 meters below the surface.

(1)What do we know about mucilage?        
A.It generally doesn't last long.
B.It had never existed before 2007.
C.It is mainly formed in inland seas.
D.It was first noticed near Turkey.
(2)What does the underlined part "an algae bloom"" in Paragraph 4 refer to?        
A.A good harvest of algae.
B.The increasing use of algae.
C.The explosive growth of algae.
D.A continuing popularity of algae.
(3)What can be inferred about mucilage from the last paragraph?        
A.It can greatly threaten sea life.
B.It has drawn attention worldwide.
C.It will lead to food shortages for humans.
D.It benefits some sea creatures but harms others.
(4)What can be a suitable title for the text?        
A.New Kinds of Algae Are Found in Turkey.
B.Turkey's Coastal Waters Are Covered with Mucilage.
C.Marmara Has Seen an Increase in Water Temperatures.
D.Endangered Sea Creatures in Marmara Have Been Protected.

218057. (2023•长安区•高二上一月) The Irish have celebrated St.Patrick's Day on March 17 every year for over 1,000 years.On this day,Irish families would attend church in the morning and celebrate in the afternoon.
   Patrick,born in Roman Britain,was brought to Ireland at the age of 16.He was thought to bring Christianity to its people.During the centuries after Patrick's death that is believed to be on March 17,461,the story of his life became popular in the Irish culture.
   However,the first St.Patrick's Day parade(游行)took place not in Ireland but in America.Recordow that a St.Patrick's Day parade was held on March 17,1601 in Florida.More than a century later,homesick Irish soldiers serving in the English army marched in New York City on March 17,1772 to honor the Irish saint(圣人).Interest in the St.Patrick's Day parades in New York City,Boston and other early American cities grew from there.In 1848,several New York Irish societies decided to unite their parades to form one official New York City St.Patrick's Day Parade.
   Today,the parade is the world's oldest parade and the largest in the United States.Each year,nearly 3 million people watch the parade,which takes more than five hours.In 2020,the New York City parade was one of the first major city events that were canceled as a result of the COVID-19 pandemic(流行病)and people are still not allowed to attend it this year.
   Although North America is home to the largest one,St.Patrick's Day is also celebrated around the world,including Japan,Singapore and Russia.In 1995,the Irish government began to use interest in St.Patrick's Day to drive tourism and show Ireland and Irish culture to the rest of the world.

217773. (2025•西安中学•高二下期末)     Cities usually have a good reason for being where they are,like a nearby port or river.People settle in these places because they are easy to get to and naturally suited to communications and trade.New York City,for example,is near a large harbour at the mouth of the Hudson River.Over 300 years its population grew gradually from 800 people to 8 million.But not all cities develop slowly over a long period of time.Boom towns grow from nothing almost overnight.In 1896,Dawson,Canada,was unmapped wilderness(荒野).But gold was discovered there in 1897,and two years later,it was one of the largest cities in the West,with a population of 30,000.
   Dawson did not have any of the natural conveniences of cities like London or Paris.People went there for gold.They travelled over snow-covered mountains and sailed hundreds of miles up icy rivers.The path to Dawson was covered with thirty feet of wet snow that could fall without warming.An avalanche(雪崩)once closed the path,killing 63 people.For many who made it to Dawson,however,the rewards were worth the difficult trip.Of the first 20,000 people who dug for gold,4,000 got rich.About 100 of these stayed rich men for the rest of their lives.
   But no matter how rich they were,Dawson was never comfortable.Necessities like food and wood were very expensive.But soon,the gold that Dawson depended on had all been found.The city was crowded with disappointed people with no interest in settling down,and when they heard there were new gold discoveries in Alaska,they left Dawson City as quickly as they had come.Today,people still come and go - to see where the Canadian gold rush happened.Tourism is now the chief industry of Dawson City - its present population is 762.

(1)What attracted the early settlers to New York City?       
A.Its business culture.
B.Its small population.
C.Its geographical position.
D.Its favourable climate.
(2)What do we know about those who first dug for gold in Dawson?       
A.Two-thirds of them stayed there.
B.One out of five people got rich.
C.Almost everyone gave up.
D.Half of them died.
(3)What was the main reason for many people to leave Dawson?       
A.They found the city too crowded.
B.They wanted to try their luck elsewhere.
C.They were unable to stand the winter.
D.They were short of food.
(4)What is the text mainly about?       
A.The rise and fall of a city.
B.The gold rush in Canada.
C.Journeys into the wilderness.

214109. (2021•长安区一中•高二上期中) If Mars were the popular kid in school,Venus(金星)would be the unwelcome one sitting in the corner,largely ignored.Venus has nearly the same mass and size as Earth,but being closer to the sun,it gets nearly twice as much heat from the sun.
   However,instead of having a climate that is just a warmer version of Earth's,Venus's surface and atmosphere are unbearable:clouds of sulphuric acid(硫酸)blanket the planet,while at ground level,it is hot enough to melt lead.Despite this,there is now a sign that Venus may harbour life.
   Jane Greaves at Cardiff University,UK,and her colleagues recently detected phosphine(磷化氢)in Venus's atmosphere,with one potential explanation that it is the by-product of biology.That is because the only way this gas is made on Earth is in laboratories or by microbes(微生物).Though this doesn't mean it was produced by life on Venus,attempts to find non-biological explanations for its presence have so far failed.
    Our best way of confirming or rejecting the possibility of life on Venus is to go and have a proper look.While Mars has been the focus of interplanetary exploration efforts lately,the phosphine discovery lets people look at Venus in a new light.As NASA administrator Jim Bridenstine tweeted: "It's time to prioritize Venus."
   In the months and years to come,computer simulations will be used to further study the possible chemistries of the atmosphere on Venus.More laboratory experiments will be conducted to try to identify other ways the phosphine there could be produced.However,there is no guarantee that these efforts will reveal the true nature of this substance on Venus.A newly-proposed strategy is to directly sample the atmosphere and surface of Venus.By doing so,we would be able to take direct measurements of phosphine.
   The discovery of phosphine in Venus's atmosphere is a great accomplishment.The scientific efforts may be just what we need to finally refocus on this neglected world.Possibly,the quiet kid in the corner may get the last laugh.

(1)Which description about Venus is not true?        
A.It has a warmer Earth-like climate.
B.It has nearly the same mass as Earth.
C.It is almost as large as Earth.
D.It has the unbearable surface and atmosphere.
(2)What can the discovery of phosphine on Venus indicate?        
A.This kind of gas is very common.
B.There might exist signs of life.
C.Many products can be made with it.
D.Experiments were once conducted there.
(3)What is paragraph 5 mainly about?        
A.The necessity to analyse phosphine.
B.The importance of observations.
C.The power of computer simulations.
D.The approaches to exploring phosphine.
(4)Which can best describe the author's attitude to the exploration of Venus?        
A.Doubtful.
B.Supportive.
C.Cautious.
D.Casual.

204203. (2023•长安区一中•高一上期末) A tiny Alaska village has experienced a boom in tourism in recent years as polar bears spend more time on land than on Arctic sea ice.
   More than 2,000 people visited the northern Alaska village of Kaktovik in 2018 to see polar bears in the wild.The far north community lies in an area where increasingly higher temperature has sped up the movement of sea ice,the primary habitat(栖息地)of polar bears.As ice has gradually moved to deep water beyond the continental shelf,more bears are remaining on land to look for food.
   Polar bears have always been a common sight on sea ice near Kaktovik,but villagers started noticing a change in the mid-1990s.More bears seemed to stay on land,and researchers began taking note of more female bears making homes in the snow on land instead of on the ice to raise their babies.U.S.Fish and Wildlife Service biologists began hearing reports of the increasing number of polar bears in the area in the early 2000s.As more attention was given to the plight(困境)of polar bears about a decade ago,more tourists started heading to Kaktovik.
   The village had fewer than 50 visitors annually before 2011,said Jennifer Reed,of the Arctic National Wildlife Refuge. "Today we're talking about hundreds and hundreds of visitors,many from around the world each year," Reed said.Most tourists visit in the fall,when bears are forced toward land because sea ice is farthest away from the shore.Bruce Inglangasak,a local hunter who sometimes offers wildlife-viewing tours,said he's been offering polar bear tours since 2004.Most of his clients(客户)are from China and Europe,as well as from the lower 48 U.S.states.Many tourists stay several days in the village,which has two small hotels.The villagers have benefited a lot from that.In turn,they provide more effective protection for polar bears with financial support from tourism development.

(1)What causes more polar bears to stay on land in Kaktovik?        
A.Food shortage.
B.Climate change.
C.Habitats' movement to shore.
D.Their preference for land.
(2)How did common people feel about more sight of bears on land?        
A.Excited.
B.Puzzled.
C.Concerned.
D.Shocked.
(3)What can be inferred from the last paragraph?        
A.Hotels in Kaktovik are in demand in autumn.
B.Kaktovik has about 50 visitors annually.
C.Inglangasak makes a living as a tour guide.
D.Tourism affects the balance of nature.
(4)Which saying can describe the text?        
A.The fittest can survive.
B.After a storm comes a calm.

202558. (2021•长安区•一模) Today we know Antarctica as an extreme environment containing ice and snow.But new research provides evidence that the area had a rainforest in the past.
   The researchers collected a piece of Earth sediment from under the seafloor off the coast of Antarctica.In the sediment,they discovered forest material that was estimated to be about 90 million years old.This would have been in the Cretaceous Period,when dinosaurs were the main land animals.The sediment was removed by scientists on the research icebreaker RV Polarstern in the Amundsen Sea near Pine Island Glacier.
   Johann Klages is a geologist with the Alfred Wegener Institute,Helmholtz Center for Polar and Marine Research in Germany.He was the lead writer of a study on the findings,published in the journal Nature.He said the sediment was collected from a depth of about 30 meters below the ocean floor.Klages said an examination showed that the material didn't form in the ocean.
   The researchers estimate that the area-about 900 kilometers from the South Pole-had average yearly temperatures of about 12 to 13 degrees Celsius.During the warmest summer months,average temperatures likely reached between 20 and 25 degrees Celsius.The soil included fine dirt particles and hard clay,as well as substances linked to at least 65 different kinds of plants,the study found.Klages added that the plants included trees,ferns and flowering plants.While no animal remains were found,Klages said there were likely dinosaurs,flying reptiles and many insects in the environment.
   The research represents new evidence of the major climate changes Earth has experienced in the past - and is currently undergoing today.The soil in the sediment dates back to the planet's warmest period of the past 140 million years,with sea level about 170 meters higher than today.The researchers said that the rainforest environment in Antarctica was especially surprising because each year,the area experiences a four-month polar night when there is no sunlight to fuel plant life.Klages said no ice sheets were present during the time,but seasonal snowfall was likely.

(1)How did the researchers reach their findings?        
A.By exploring ice in Antarctica.
B.By analyzing the Earth sediment.
C.By collecting data on climate.
D.By researching special plants.
(2)What did the researchers say about the sediment?        
A.Its material developed in the ocean.
B.It dates back to cold times in Antarctica.
C.Its material formed on the land.
D.It contained different animal remains.
(3)What does the author indicate in the last paragraph?        
A.Antarctica's natural environment has changed greatly.
B.Polar nights in Antarctica are getting shorter than before.
C.There were ice sheets 140 million years ago.
D.Seasonal snowfall made the forest disappear.
(4)What is the main idea of the text?        
A.Researchers study the secrets of Antarctica.
B.Antarctica had a different history of climate.
C.There's various wildlife in Antarctica.
D.Antarctica has an extreme environment containing ice and snow.

202521. (2021•西安中学•二模) Plants:we eat them,juice them - and now it seems we can mine them too!
   After a successful experiment on the island of Borneo,the botany professor Alan Baker and a group of researchers want to introduce phytomining (harvesting minerals from plants) as a better,partial substitute for traditional mining.
   Phytomining,also known as agromining,means collecting metals from live plants.However,this can only be done with a group of plants known as "hyperaccumulators".There are around 700 identified types worldwide,and what makes these hyperaccumulators special is that they naturally attract and absorb minerals through their roots - metals poisonous to other plants - and then store huge,pure concentrations of these minerals in their bodies.The metals can then be extracted from the plants' sap(汁;液),oil,or sometimes even live tissue.
   Baker and his colleagues see a lot of potential in phytomining.Not only can it help meet the growing global demand for metals,but is a way of undoing some of that damage to the environment by traditional mining.
   One of the biggest problems with traditional mining is that it pollutes the surrounding area.Phytomining can extract metal waste,plus planting the hyperaccumulators would regrow the deforested areas caused by mining operations.Aside from this,if phytomining is able to replace part of traditional mining,then there would be fewer instances of bad mining practices like abandoned mines,which pollute the nearby waters.Also,since phytomining provides metals that are already naturally pure,there is no need to use huge amounts of energy to purify the ore(矿石).
   Phytomining has its drawbacks.Harvesting plants on a large scale is expensive today,compared to traditional mining.Besides,plants can be wiped out by diseases or unexpected weather conditions.
   However,there are many reasons to consider phytomining.After all,we need to make sure that our planet can keep up and sustainable practices like phytomining give us the hope that our advancement doesn't mean sacrificing Mother Earth.

202283. (2022•西工大附中•七模) In the town of Arras in northern France,the country's first-ever appointed official with Down syndromes is leading from the front,changing hearts and minds and bringing a new way of thinking about mental disability.
   In 2020,Eleonore Laloux was appointed municipal councilor(市议员)of Arras under the mayor Frederic Leturque,for which she has received continual praise for her colorful nature,her desire to make people smile,and for promoting the inclusivity(包容)of disabled persons in society.
   "Inclusion isn't something that we just think about;it's not a generous act.It's our duty," Mayor Leturque told the Christian Science Monitor, "Eleonore has helped the entire town progress in terms of how we see disability."
   Along with holding down a part-time job at a hospital,a packed volunteer schedule,and a board position on Down Up,a non-profit organization her father launched to support community members with Down syndromes and their families,Laloux has made numerous adjustments to everyday community features in Arras to support disabled people;not only those with Down syndromes,but other forms as well.
   Arras' famous town center,town hall,and belfry(钟楼)are a UNESCO Heritage Site,and for those who can't go to the top,Laloux organized the creation of a virtual tour.Down below,crosswalk lights now sound off verbal instructions for those who can't see.She has also scheduled an "incluthon" for next summer,an event to inspire disabled people and the community at large through sports and culture.
   Perhaps unsurprisingly,this positive attitude has made her a very popular figure in her town and country,and she has made numerous television and other public appearances,including alongside many national politicians.But her appointment is by no means a gimmick to gain support from townspeople;she's made some brilliant changes in civil life.

(1)What can we learn from the mayor's words in Paragraph 3?        
A.It's Eleonore's duty to help the disabled.
B.Accepting the disabled is a generous act.

220435. (2015•长安区一中•高三上一月) It's not easy growing up.Growing up can be a real"pain"for some of us.Sometimes we feel worried,sometimes we feel sad,sometimes we are fearful,and sometimes we just don't understand why we can't stay young forever.But we should take a look back on all the hardships in life with a positive attitude and learn from them.We must overcome every obstacle one small step at a time.We should realize that all of our growing pains actually turn into growing gains!
Throughout our lives we are going to face many challenges and pains,but we should never let these obstacles keep us from following our dreams.
As a young girl,my parents forced me to do so many things that I didn't like.They made me learn to play the violin and then the piano.At that time I hated music and I also hated them.But looking back now,I am so glad that my parents encouraged me to take music lessons.Music has enriched my life in so many ways.I now realize that my parents and teachers wanted me to have a better life than they did themselves.
We are all going to experience growing pains,but they are just part of our life.They might seem so huge at the time,but we must be strong.Think about how we would feel if we had no challenges and lived a life like that.Life would be really boring and meaningless.The future is ours!A little hard work and sweat never hurt anyone!If we realize that these pains are just small bumps on our road to success,we will realize that our growing pains are actually growing gains!

201693. (2024•西工大附中•模拟) California has lost half its big trees since the 1930s,according to a study to be published Tuesday and climate change seems to be a major factor.
    The number of trees larger than two feet across has declined by 50 percent on more than 46,000 square miles of California forests,the new study finds.No area was spared or unaffected,from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles.In the Sierra high country,the number of big trees has fallen by more than 55 percent;in parts of southern California the decline was nearly 75 percent.
   Many factors contributed to the decline,said Patrick Mclntyre,an ecologist who was the lead author of the study.Woodcutters targeted big trees.Housing development pushed into the woods.Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources(资源).
   But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010,Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.
    The loss of big trees was greatest in areas where trees had suffered the greatest water shortage.The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed,taking into account such things as rainfall,air temperature,dampness of soil,and the timing of snowmelt(融雪).
   Since the 1930s,Mclntyre said,the biggest factors driving up water stress in the state have been rising temperatures,which cause trees to lose more water to the air,and earlier snowmelt,which reduces the water supply available to trees during the dry season.

(1)What is the second paragraph mainly about?        
A.The seriousness of big-tree loss in California.
B.The increasing variety of California big trees.
C.The distribution of big trees in California forests.
D.The influence of farming on big trees in California.
(2)Which of the following is well-intentioned but may be bad for big trees?        
A.Ecological studies of forests.
B.Banning woodcutting.
C.Limiting housing development.
D.Fire control measures.
(3)What is a major cause of the water shortage according to Mclntyre?        
A.Inadequate snowmelt.
B.A longer dry season.
C.A warmer climate.
D.Dampness of the air.
(4)What can be a suitable title for the text?        
A.California's Forests:Where Have All the Big Trees Gone?
B.Cutting of Big Trees to Be Prohibited in California Soon.
C.Why Are the Big Trees Important to California Forests?
D.Patrick Mclntyre:Grow More Big Trees in California

201826. (2024•西安中学•九模) In February of 1942,Mexican farmer Dionisio Pulido thought he heard thunder coming from his cornfield.However,the sound wasn't coming from the sky.The source was a large smoking break sending out gas and pushing out rocks.This opening would come to be known as the volcano Paricutin,and over the next 9 years,its lava and ash would cover over 200 square km.But where did this new volcano come from,and what caused its unpredictable eruption?
   One of the most common causes of an eruption is an increase in magmastatic(静磁)pressure.Magma(岩浆)contains various elements and compounds.At high enough concentrations,compounds like water or sulfur(硫)form high-pressure gas bubbles.When these balls of gas reach the surface,they can burst with the force of a gunshot.And when millions of bubbles explode,the energy can send ash into the air.But before they pop or burst,they act like bubbles of CO2 in a shaken soda.
   Not all eruptions are due to rising magmastatic pressure- sometimes the weight of the rock above can become dangerously low.Landslides can remove massive quantities of rock from atop a magma chamber or room,dropping the pressure and instantly touching off an eruption.This process is known as "unloading" and it's been responsible for numerous eruptions,including the sudden explosion of Mount St.Helens in 1980.But unloading can also happen over longer periods of time due heating ice or melting glaciers.In fact,many geologists are worried that glacial melt caused by climate change could increase volcanic activity.
   Unfortunately,knowing what causes eruptions doesn't make them easy to predict.While scientists can roughly determine the strength and weight of the Earth's crust(地壳),the depth and heat of magma chambers makes measuring changes in magmastatic pressure very difficult.But volcanologists are constantly exploring new technology to overcome this rocky field.Advances in thermal imaging(热成像)have allowed scientists to detect underground hotspots.Spectrometers can analyze gases escaping magma.Hopefully,these tools will help us better understand these gas breaks and their explosive eruptions.

(1)Why does the author mention the story of a farmer in the first paragraph?        
A.To show the power of volcano eruption.
B.To introduce the topic.
C.To introduce the volcano Paricutin.
D.To explain the reason.
(2)What does the underlined word "they" in paragraph 2 refer to?        
A.The bubbles of CO2 .
B.The ash of the volcano.
C.Gas bubbles of compounds.
D.The elements of a soda.
(3)Which of the following is true about the eruption of Mount St.Helens?        
A.Landslideould be responsible for its eruption.
B.It began to explode over a long period of time.
C.The process of "unloading" occurred after its explosion.
D.The weight of the rock above it increased as to cause its eruption.
(4)What can we infer from the last paragraph?        
A.Scientists can determine the eruption of volcano in advance.
B.It is quite difficult to measure the weight of the Earth's crust.
C.Spectrometers can help scientists to detect underground hotspots.
D.Scientists are positive about further study of volcano eruption.

201968. (2023•长安区•一模) Electronic sensors built into paper could be used in a range of ways from information storage to touch screens and more.
   Electronic sensors built into cartons(纸盒)may make it easier to tell when it's time to throw out rotten milk or orange juice.And that's just the start.At least that's the goal for researchers working on putting electronics into paper.They're trying to figure out how to combine the flexibility,low-cost and recyclability of paper with the information-carrying ability of electronics.
   Daniel Torbjork,a physics graduate student in Finland,has been working on the problem.He's published a review of the field in the journal Advanced Materials.
   Much research has been focused in this area.While most electronic applications require patterned conducting structures,conductive paper could be used in applications such as energy storage devices,sensors,electric heaters and others,according to Torbjork.
   "You could even have some interactive functions in magazines," Torbjork said,"You could put a simple game in a package.If you want a touch screen,press a button and then something happen.Sensors in paper could tell us when something has gone bad."
   Additional applications,such as information storage and security paper,have been suggested for magnetic papers containing magnetite.In Massachusetts,researchers have figured out how to post a video of such a device put into a paper airplane.
   German researchers have also put electronic chips in paper bank notes to defend counter-feiters(造伪币者).Paper is a good material but printing electronics also requires low-cost manufacturing.As many US and European paper makers lose market share to cheaper paper from China,these big paper companies are looking for added value products.That's where electronic paper devices could make a difference.
   "The major obstacles are paper's large surface roughness and chemical impurities." Torbjork says.But others in the field think that electronic sensors in paper are still far from the consumer marketplace.
   "I don't think it's going to happen." said Roy Horgan. "You need a conductive surface.It could be 10 years out.What we are looking for are solutions that you can commercialize today."
   Solar Print is partnering with Italian automaker Fiat to develop a unique auto-glass with tiny photostatic cells(光电)that can capture electricity from the sun.In the meantime,using paper to conduct electricity is still a "blue-sky" project.
   "I would love to see someone prove me wrong,because that means that it's actually happening." Horgan said. "If someone comes up with conductive paper,then that's a very interesting technology."

(1)Putting electronics into paper will        .
A.cut the cost and impurity of paper
B.depend on flexible conductive structure
C.help consume rotten milk or orange juice
D.combine the advantages of paper and electronics
(2)Paragraphs 4 to 7 mainly talk about the         of the conductive paper.
A.theories
B.structures
C.practical use
D.design process
(3)Some paper makers welcome the new technology probably because it will         .
A.add more value to paper
B.make the paper smoother
C.put an end to fake money
D.improve the printing technology
(4)From the passage,we know that Roy Horgan        .
A.has a burning desire to make a great profit
B.started a "blue-sky" project to study paper
C.is not confident about the conductive paper
D.showed much interest in Solar Print industry
