281867. （2025•华清中学•高三上期中）        Fishing is a way of life for people who live on the floating villages of Cambodia's Tonle Sap Lake.These Southeast Asians depend on fish in the lake.But those fish are in trouble.
       Overall，their numbers in Tonle Sap Lake have been falling sharply.Compared to the number in 2003，just 12 percent as many could be found in 2019.Chevalier was part of a team that shared those data in Science of the Total Environment. "If the tendency continues，" he says， "there will be nothing for people there to eat any more."
       Dams （大坝） are a big problem，Chevalier says.These structures break up river systems.With growing human populations，overfishing becomes more of a threat.As people keep fishing，the share of fish left there could decrease even more.Pollution threatens freshwater ecosystems，too.People have also been changing the land in ways that damages the habitat in lakes and streams.And then there's a growing number of non-native harmful species.Lastly，global warming has been causing harm by stressing both fish and their food sources.
       Still，the situation isn't hopeless.Researchers are working to identify the most effective ways to change that.One way is to remove outdated or ill-placed dams.The largest such U.S.project took down four dams from the lower Klamath River.Soon after，thousands of salmon （鲑鱼） were swimming upstream through this newly opened stretch.Elsewhere，dam operators can reduce harm by changing river flows.Limiting flow too much can cause downstream areas to dry up.Smarter dam placement would also help.
       "Restoring habitat can help if done right.But this work costs money.And it's hard to restore entire streams，" John Gray，a fish biologist，says.In 2022，scientists tried repopulating some fish species at Tonle Sap Lake.However，nearly half the fish were caught less than three months later.
       With each success or failure，scientists learn how better to deal with these big problems.Teens can get involved.Many conservation groups welcome help from people of any age.
32. Why is fishing mentioned in the first paragraph？
A.To present a way of living.
B.To state the best fishing place.
C.To lead to the main concern.
D.To stress the value of tradition.
33. Which of the following is a way to settle the problem caused by dams？
A.Increasing the use of dams.
B.Turning dams into river habitats.
C.Choosing the locations for dams wisely.
D.Limiting the river water flowing downstream.
34. What does Gray think of restoring habitat？
A.It has limited benefits.
B.It is useless.
C.It will bring worse results.
D.It is money-saving.
35. What is the best title of the text？
A.Remove Old Dams
B.Threats to Southeast Asian Population
C.Benefits of Protecting Fish
D.Help Tonle Sap Fish Survive

203977. （2024•高新一中•高二下期末） Soot （煤） pollution is speeding up climate-driven melting in Antarctica，a new study suggests，raising questions about how to protect the delicate continent from the increasing number of humans who want to visit.
"It really makes us question，is our presence really needed？" says Alia Khan，one of the authors of the new study. "We have quite a large black carbon footprint in Antarctica，which is enhancing snow and ice melt."
   Black carbon is the leftover thing from burning plants or fossil fuels.Soot in Antarctica comes primarily from waste gases of cruise ships （游轮），vehicles and airplanes，although some pollution travels on the wind from other parts of the globe.The dark particles （微粒） coat white snow and absorb heat from the sun the way a black T-shirt does on a warm day.The blanket of dark bits speeds up melting that was already happening more quickly because of global warming.
   When snow and ice are uncovered，they reflect an enormous amount of sunlight before it can turn into heat. "These are the mirrors on our planet，" says Sonia Nagorski，a scientist at the University of Alaska Southeast. "When those mirrors are covered in a film of dark bits，they don't send back that much light and heat.That means more heat is trapped on Earth，speeding up melting and contributing to global warming."
   As a scientist who personally visits Antarctica every year，Khan saye is troubled by her own research results.On the one hand，she goes to Antarctica to collect crucial data about how quickly the snow and ice there are disappearing. "But then when we come to conclusions like this it really does make us think twice about how frequently we need to visit the continent，" she says， "and what kind of regulationould be placed on tourism as well." That could mean requiring that cruise ships and vehicles be electric，for example，or limiting the number of visitors each year.

（1）What is Khan's attitude towards human actions in Antarctica according to paragraph 2？
A．Angry and abusive.
B．Cold and uninterested.
C．Doubtful and anxious.
D．Admiring and delighted.
（2）What is the main cause of soot pollution in Antarctica？
A．The quick melting of ice and snow.
B．The emission from virous transport.
C．The remaining parts of burning plants.
D．The floating gases from other continents.
（3）What do we know from Nagorski？
A．The covered ice is less reflective.
B．The melting speed of ice is slower than before.
C．The dark blanket serves as a big mirror.
D．The sunlight gets increasingly stronger recently.
（4）Which is the most suitable title for the text？
A．What made our planet so polluted？
B．Who is to blame for air pollution？
C．Can electric vehicles save tourism？
D．Are we welcome to the South Pole？

201845. （2024•西安一中•二模）     A carbon footprint is only one component of the broader ecological footprint.An ecological footprint compares the population's consumption of resources and land with the planet's ability to regenerate.The Earth's ecological footprint is currently 23 percent over capacity.It takes about one year and two months to regenerate what we consume in a year.
    Carbon footprints help people keep track of changes.Because footprints quantify an amount of carbon that increases or decreases based on energy use，they let people know that a new hybrid car or home insulation （隔离） helps.Transportation accounts for 33 percent of CO₂ emissions in the United States，so many people try to lower their mileage （里程）.Some walk or bike whenever possible；others take public transport.Home energyuse accounts for 21 percent of U.S.CO₂ emissions，so it helps to have an efficient home.Setting the thermostat （恒温器） at a moderate temperature and installing double-paned windows lowers energy costs.
    Of course，individual efforts can go only so far.Cutting CO₂ and other greenhouse gases down to safer levels requires significant government regulation.Lessening carbon footprints does let people see where they are and how they can change.Those who want to accept personal responsibility for their emissions can track their own reductions and change their habits.
    Because carbon calculators ask for only rough estimates，it's easy for investigators to approximate the footprints of celebrities and politicians.Analysts hope to uncover high-profile figures，especially those who promote environmentalism.Although performer Madonna and other celebrities have been accused of flying frequently，former vice president Al Gore has drawn the harshest accusations.The Gores' spokesperson did not deny that but emphasized that the couple subscribes to green power.

（1）How long can the Earth produce what we need in a year？        ?
A.2 months.
B.12 months.
C.14 months.
D.23 months.
（2）What is the second paragraph mainly about？        ?
A.Why people are worried about CO₂ emissions.
B.How individuals can help to lower CO₂ emissions.
C.Where most CO₂ emissions come from in the United States.
D.What measures have been taken to cut down CO₂ emissions.
（3）What is still needed to cut greenhouse gases down to safer levels？        ?
A.The participation of the public.
B.The development of new equipment.
C.The changes of our living habits.
D.The powerful efforts of the government.
（4）Why do investigators estimate the footprints of famous people easily？        ?
A.Because they have mastered methods.
B.Because it doesn't call for much accuracy.
C.Because famous people are easy to approach.
D.Because new technology has advanced greatly.

205078. （2022•蓝田县•高一上期末） The Chinese paddlefish（白鲟）-one of the world's largest freshwater fish-has been announced extinct.Scientists say the paddlefish，also called the Chinese swordfish，is believed to have a lineage dating back at least 34 million years.With its long nose and mouth，the paddlefish could grow as long as seven meters.
But a research paper recently published in Science of the Total.Environment reported the paddlefish was now extinct.The researchers include scientists from the Chinese Academy of Fishery Sciences，Britain's University of Kent and the University of South Bohemia in the Czech Republic.
   The paper says the paddlefish was announced extinct for two reasons.It said that the fish was not able to survive because of widespread overfishing and damage to its native environment in the Yangtze River.
Researchers discovered 332 different species of fish in the Yangtze River in 2017 and 2018.But they did not find a single Chinese paddlefish.They guessed the fish disappeared between 2005 and 2010.The extinction of the Chinese paddlefish was "a huge loss" to nature.
   Pan Wenjing is a forest and ocean expert with Greenpeace East Asia. "The ecology of the Yangtze River is almost in ruins due to human activity in past decades" Pan said.She stressed that China had taken measures to improve the Yangtze's environment，including a 10-year ban（禁令）on fishing.
   After the extinction was reported in the news，some Chinese media and Internet users look a look back at the large creatures.Many people appeared to have not heard of the Chinese paddlefish before it was announced extinct.
   "Every time I see the news of another species going extinct，my heart starts to ache， "wrote one Weibo user. "Humanould not live alone on this planet， " the user added.

（1）What do we know from Paragraph 3？
A．Fishing in the Yangtze River.

204960. （2022•阎良区•高二上期末） You've heard that plastic is polluting the oceans-between 4.8 and 12.7 million tonnes enter ocean ecosystems every year.But does one plastic straw or cup really make a difference？Artist Benjamin Von Wong wants you to know that it does.He builds massive sculptures out of plastic garbage，forcing viewers to re-examine their relationship to single-use plastic products.
   At the beginning of the year，the artist built a piece called "Strawpocalypse，" a pair of 10-foot-tall plastic waves，frozen mid-crash.Made of 168，000 plastic straws collected from several volunteer beach cleanups，the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City，Vietnam.
   Just 9% of global plastic waste is recycled.Plastic straws are by no means the biggest source of plastic pollution，but they've recently come under fire because most people don't need them to drink with and，because of their small size and weight，they cannot be recycled.Every straw that's part of Von Wong's artwork likely came from a drink that someone used for only a few minutes.Once the drink is gone，the straw will take centuries to disappear.
   In a piece from 2018，Von Wong wanted to show a specific statistic：Every 60 seconds，a truckload's worth of plastic enters the ocean.For this work，titled "Truckload of Plastic，" Von Wong and a group of volunteers collected more than 10，000 pieces of plastic，which were then tied together to look like they'd been dumped（倾倒）from a truck all at once.
   Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

（1）What are Von Wong's artworks intended for？
A．Beautifying the city he lives in.
B．Drawing public attention to plastic waste.
C．Introducing eco-friendly products.
D．Reducing garbage on the beach.
（2）Why does the author discuss plastic straws in Paragraph 3？
A．To explain why they are useful.
B．To voice his views on modern art.
C．To show the difficulty of their recycling.
D．To find a substitute for them.
（3）What effect would "Truckload of Plastic" have on viewers？
A．Worrying.
B．Calming.
C．Refreshing.
D．Challenging.
（4）What is the main idea of the text？
A．Artists's opinions on plastic safety.
B．Media interest in contemporary art.
C．Responsibility demanded of big companies.
D．Ocean plastics transformed into statues.

204480. （2023•莲湖区•高一上期末） Polar bears generally use sea ice to hunt （捕猎），but a newly discovered group has found another way.An isolated （与世隔绝的） population of polar bears has been discovered in a fjord （峡湾） in southeast Greenland，which is free of sea ice for most of the year.Polar bear generally need sea ice to survive，so the discovery is raising hopes that some kinds of the polar bears might survive the loss of sea ice caused by global warming.
   Researchers found the population living in a fjord in the southeast Greenland，which is surrounded by mountains and an ice sheet to the west，and ocean to the east.The sea-ice coverage lasts for only around 100 days each year.With sea ice in the fjord becoming smaller because of global warming，the whole group were expected to die out by the end of this century.
   But the isolated population has found a way to hunt without sea ice.The group，about 27 adult females，has been isolated from other polar bear populations along Greenland's east coast for at least 200 years.
   Tracking data from marked bears proves that they don't move far.For example，when members of the group went out of the fjord，the ice on which they sat sometimes got caught in the rapid water flow. "Whenever this happened，they would get stuck and then，they would have to jump off，swim to the beach and walk back home empty-handed，" says lead author Kristin Laidre，an animal ecologist at the University of Washington in Seattle.
   Though the researchers failed to video their hunting without sea ice，the existence of this small population in conditions of low sea-ice coverage suggests there is a chance that the population can survive，even as sea ice flows away to farther north each year.

（1）What have the newly discovered polar bears found？
A．A place filled with ice sheets.
B．A way to hunt without sea ice.
C．A way to track sea ice flowing away.
D．An ice sheet caught in the rapid water flow.
（2）Why were polar bears in the fjord expected to die out？
A．They are being hunted by human.
B．They have lost their source of food.
C．They can't stand the increasing heat.
D．The sea ice there is becoming smaller.
（3）What can be inferred from the text？
A．The bears can swim very far to hunt for food.
B．Kristin Laidre is negative about the future of the group.
C．Once the group went out of the fjord，they might get into trouble.
D．If the bears got caught in the rapid water flow，they wouldn't go home.
（4）Which is the most suitable title for the text？
A．Polar bear population can survive without sea ice
B．Sea ice is becoming smaller because of the global warming
C．Polar bear population may die out because of the global warming
D．A newly discovered polar bear population has been stuck in a fjord

204393. （2023•铁一中学•高二下期末） In southeastern Brazil，local fishers walk into dark waters in search of mullet （鲻鱼） On their own，it would be tricky to find the silvery fish.But the humans get help from an unusual partner：wild bottlenose dolphins.
   With nets in hand，the fishers patiently wait as their cetacean （鲸类的） partners drive the fish toward the shore.A signal from the dolphins—usually a deep dive—indicates when they should cast their nets.This fishing partnership has passed down through the generations，lasting for more than a century.
   While researchers knew humans profited from this pairing，they couldn't confirm whether it benefited the dolphins.Now，in a new study in Proceedings of the National Academy of Sciences，researchers suggest cetaceans that hunt with humans have more chances to live than those that don't.
   "Human-wildlife cooperation in general is a rare phenomenon at a global scale." says Mauricio Cantor，a biologist at Oregon State University and leader of the study. "Usually humans gain the benefit，and nature pays the cost.But this interaction has been happening for over 150 years."
   Fishers were more successful when they worked with the dolphins.When dolphins were present，the fishers were 17 times more likely to catch prey （猎物） and netted nearly four times more mullet when they timed their casting with the cetaceans' signals.Eighty-six percent of all 4.955 mullet caught during the study period came from "synchronous （同时的） interactions"—when the allies organized their actions perfectly with one another.
   The study also revealed dolphins hunting with humans had a 13 percent increase in survival rate over other dolphins.These cooperative dolphins are more likely to stay near the shore，reducing their chance of entanglement （缠绕） in illegal fishing equipment.Besides，the dolphins can take some fish directly from the fishers' harvest.

（1）What do the first two paragraphs talk about concerning Brazilian fishers？
A．They trick dolphins into fishing for them.
B．They harvest more fish with dolphins' help.
C．They have been training dolphins over a century.
D．They cast the fishing nets when dolphins surface.
（2）What does Mauricio Cantor's research show？
A．Nature favors human beings at a huge cost.
B．Fishers benefit from cooperating with cetaceans.
C．Human-wildlife interaction is a new global trend.
D．Dolphins working with man have higher survival rate.
（3）What does the underlined word "allies" refer to in paragraph 5？
A．Prey.
B．Mullet.
C．Partners.
D．Researchers.
（4）What's the author's main purpose in writing the text？
A．To appeal for the protection of sea creatures.
B．To show a unique human-dolphin relationship.
C．To applaud for development in fishing research.
D．To encourage fishers to better draw on dolphins.

204108. （2023•西安中学•高二上期末） Climate change disproportionately affects the world's most vulnerable people，particularly poor rural communities that depend on the land for their livelihoods and coastal populations throughout the tropics.We have already seen a chain of tough suffering that results from extreme weather events，such as hurricanes，floods，droughts，wildfires，and more.
   For remedies，advocates and politicians have tended to look toward cuts in fossil-fuel use or technologies to capture carbon before it enters the atmosphere—both of which are crucial.But this focus has overshadowed the most powerful and cost-efficient carbon capture technology in the world.Recent research confirms that forests are absolutely essential in reducing climate change，thanks to their ability to absorb and isolate carbon.In fact，natural climate solutions such as conservation and restoration of forests，along with improvements in land management，can help us achieve 37 percent of our climate target of limiting warming to a maximum of two degrees Celsius above preindustrial levels，even though they currently receive only 2.5 percent of public climate financing.
   Forests' power to store carbon dioxide is staggering：one tree can store an average of about 48 pounds in one year.Intact（完整的）forests could take in the CO₂ emissions of some entire countries.
   For this reason，policymakers and business leaders must create and enforce policies to prevent deforestation，foster，reforestation of degraded land，and promote the sustainable management of standing forests in the fight against climate change.Protecting the world's forests ensures they can keep performing essential functions such as producing oxygen，filtering water and supporting biodiversity.Not only does the world's entire population depend on forests to provide clean air，clean water，oxygen and medicines，but 1.6 billion people also rely on them directly for their livelihoods.
   Unfortunately，a huge amount of forest continues to be converted into agricultural land to produce a handful of resource-intensive commodities - despite zero-deforestation commitments from companies and governments.So now is the time to increase forest protection and restoration.This action will also address a number of other pressing global issues.For example，in less developed，rural areas - especially in the tropics - community-based forest-management programs can forge pathways out of poverty.In the Peten region of Guatemala，for instance，community-managed forests boasted a near-zero deforestation rate from 2000 through 2013，as compared with 12 percent in nearby protected areas and buffer（缓冲）zones.These communities have built low-impact，sustainable forest-based businesses that have stimulated the economy of the region enough to fund the creation of local schools and health services.Their success is especially noticeable in a location where，outside these community-managed zones，deforestation rates have increased 20-fold.

（1）Which of the following statements about natural climate solutions is true according to the passage？
A．They are the only effective strategies available to address the climate change.
B．They pale in comparison with the reduction in fossil-fuel use or technologies.
C．They can and should play a more important role in cutting carbon emissions.
D．They manage to limit warming to two degrees Celsius above pre-industrial levels.
（2）The word "staggering" （Paragraph 3）is closest in meaning to "        ".
A．documented
B．incredible
C．unsteady
D．negligible
（3）Which of the following statements is the author most likely to agree with？
A．The policies to prevent deforestation have borne fruit.
B．Developed countries are hit the hardest by climate change.
C．Economic growth contributes a lot to reducing deforestation.
D．Some governments fail to keep their promises to preserve forests.
（4）What does the passage mainly talk about？
A．Keeping forests undamaged can go a long way toward saving the planet.
B．A high-tech climate fix is required to dramatically lessen global warming.
C．Governmentould work together with businesses to stop deforestation.
D．Sustainable management of forests is crucial in powering regional development.

238987. （2024•全国•新高考Ⅱ） ?We all know fresh is best when it comes to food.However，most produce at the store went through weeks of travel and covered hundreds of miles before reaching the table.While farmer's markets are a solid choice to reduce the journey，Babylon Micro-Farm （BMF）shortens it even more.
?BMF is an indoor garden system.It can be set up for a family.Additionally，it could serve a larger audience such as a hospital，restaurant or school.The innovative design requires little effort to achieve a reliable weekly supply of fresh greens.
?Specifically，it's a farm that relies on new technology.By connecting through the Cloud，BMF is remotely monitored.Also，there is a convenient app that provides growing data in real time.Because the system is automated，it significantly reduces the amount of water needed to grow plants.Rather than watering rows of soil，the system provides just the right amount to each plant.After harvest，users simply replace the plants with a new pre-seeded pod（容器） to get the next growth cycle started.
?Moreover，having a system in the same building where it's eaten means zero emissions（排放） from transporting plants from soil to salad.In addition，there's no need for pesticides and other chemicals that pollute traditional farms and the surrounding environment.
?BMF employees live out sustainability in their everyday lives.About half of them walk or bike to work.Inside the office，they encourage recycling and waste reduction by limiting garbage cans and avoiding single-use plastic."We are passionate about reducing waste，carbon and chemicals in our environment，"said a BMF employee.

（1）What can be learned about BMF from paragraph 1？
A.It guarantees the variety of food.
B.It requires day-to-day care.

203938. （2024•鄠邑二中•高一下期末）     Bumblebee （大黄蜂） populations have declined （下降） by 90 percent in the past 20 years.The decline of the bumblebees is highly concerning as they are significant for ecosystems.They pollinate （授粉） flowers and crops.If their populations were to continue to decline，crops would not be able to produce fruits and vegetables.Despite being small，they are important to nature's balance.
    And now，a new study published in the Frontiers in Bee Science has found that the rising heat caused by global warming might be a reason for the decrease in numbers across the globe. "The decline in populations and ranges of several species of bumblebees may be explained by issues of overheating of the nests，" Peter Kevan of the University of Guelph in Canada and lead author of the study said in a statement.
    Kevan and his colleagues decided to take a closer look at the facts relating to bumblebee populations across the world.Kevan and the colleagues looked at 180 years of literature on the species and found one common reason across all bumblebee species that they can survive in temperatures up to 36 degrees Celsius，but the perfect temperature for nests is between 28 to 32 degrees Celsius.They are unlikely to be able to adjust themselves to the extent that rising temperatures due to climate change require，the study reports.While individual bees may be able to deal with increased heat better than others，the study notes that if nests are too hot，the groups will not survive.
    "The effect of high nest temperatures has not been studied very much，which is surprising，" Kevan said.Similar studies have been done on honeybees （蜜蜂），another threatened yet highly important species.This suggests further that heat stress is a major factor in bees' overall decline.
    Although the studies led by Kevan have limitations，the potential effects for bumblebee health and conversation are large and long-term.

（1）What do we know about bumblebees from paragraph 1？
A.They have been extinct within decades in America.
B.Their populations have decreased a lot in the last two decades.
C.Americans are concerned about their living environment.
D.They tend to depend on flowers and crops to survive.
（2）How did Kevan and his coworkers carry out the study？

203658. （2024•师大附中•高二上期末） Transport is undergoing a massive transformation so it can meet society's demands for a low- carbon economy.Introducing electric vehicles （EV） and declining gasoline use are helping，but zero-carbon hydrogen can speed up both the transition （转变） and long-term decarbonization of transport.
   In the US，transportation produces the largest share of all greenhouse gas emissions （排放） in the economy at 29%，according to the Environmental Protection Agency.More than 90% of transport fuel is petrol based，but if more vehicles used hydrogen，emissions of this kind would plummet.
   However，hydrogen is not considered an ideal replacement for gasoline as an engine fuel for cars because it is harder to store safely.And while fuel cell electric vehicles （FCEVs） that turn hydrogen into electricity can compete with EV performance-and even out-compete them on range and refill time，extra energy is needed to produce the hydrogen needed for fuel.Also，finding investment for storage，pipelines and fuel stations is still a challenge for many nations.
   Currently，governments worldwide are backing green hydrogen projects to reduce greenhouse gas emissions in heavy industries like freight （货运），steel，and energy storage.But hydrogen transport will need rapid production methods to create the fuel needed for the world's road fleet.
   Thankfully，research is advancing all the time.Nanoscale （纳米级的） thin films are applied to improving the chemical process to rapidly harvest hydrogen from the seawater.The same technology has been successfully used in solar power devices with higher efficiency-to-cost rates.Since hydrogen is the most abundant element in the universe and as seawater makes up about 96% of all water on Earth，there is a virtually limitless supply.
   Even wastewater and solid waste can create green hydrogen.Researchers at Princeton University are using sunlight to separate hydrogen from industrial wastewater.Chemical plants that currently face high costs for cleaning wastewater could transform it into clean hydrogen supplies.

（1）What does the underlined word "plummet" mean in Paragraph 2？
A．Stop.
B．Decrease.
C．Continue.
D．Disappear.
（2）What is Paragraph 3 mainly about？
A．Ways of storing hydrogen safely.
B．Benefits of fuel cell electric vehicles.
C．Challenges of using hydrogen as car fuel.
D．Differences between gasoline and hydrogen.
（3）What makes it more efficient to get hydrogen from the ocean？
A．The application of solar power devices.
B．The method of identifying water elements.
C．The invention.of the water transport system.
D．The use of the nanoscale thin-film technology.
（4）Which of the following can be a suitable title for the text？
A．Clean Energy Hydrogen Ready to Take Off.
B．Traditional Fuels Bound to Reach a Dead End.
C．How We Can Generate Energy from Hydrogen.
D．What the Future of Transportation May Be Like.

203573. （2025•临潼区•高一上期末）     An adult African elephant consumes about 223 liters of water and 3，080 pounds of roots，grass and fruit daily.That's like having 634 cans of soda and 1，200 hamburgers every day.This keeps them moving thousands of miles across Africa each year.Elephants usually migrate between March and May.Females live in groups with their children，and quickly run out of the food supply.They hit the road in search of food.Male elephants live alone，so they don't use resources as quickly as the females.Instead，they migrate during their mating cycle.When the females pack their trunks，so do the males.
   During migration，elephants face short water supplies and extremely high temperatures.But people are their number-one problem.Poachers（偷猎者） kill 35，000 elephants each year for ivory.Many African farmers build fences（栅栏） to protect crops and cattle，which might block regular migration paths.Traffic roads affect elephant migration，too.During one study of 28 elephants in Central Africa，only one female crossed an unprotected road.
   Scientists，wildlife organizations and governments cooperate to find solutions for Africa's elephants."To unlock the secret of where elephants move and how they move，we place collars（项圈）with a satellite unit inside，"Dr.Michael Chase says.GPS collars help map which routes elephants use most so that countries can establish protected elephant passages.
    Locals come in as well.James Isiche，East Africa Director of the International Fund for Animal Welfare says，"We have got the community on our side by a project；they've agreed to partner with us to conserve elephants."The local community run wildlife parks to attract tourists."This project helps us take care of both the wildlife and our cows，""says Sikira，a tribal elder in Maasai，Kenya.Protecting elephant migration routes allows these gentle giants to survive.

（1）What can we learn about the elephants from paragraph 1？
A.They show an interest in hamburgers.
B.They move south to survive the cold.
C.They migrate for different reasons.
D.Females live shorter for food shortage.
（2）What is paragraph 2 of the text mainly about？
A.Results of poaching.
B.Reasons for killing elephants.
C.Difficulties in migrating.
D.Efforts to protect migration paths.
（3）Why are collars applied by scientists？
A.To discover the secret of migration.

201825. （2024•西安中学•九模）     From the world's last seven to a global population of more than 5，000，China spent nearly 40 years bringing back crested ibises（朱鹗）from the edge of extinction.
    With its typical red crest and face，as well as a long black mouth and snow-white feathers，the crested ibis is known as "the oriental gem" in China.They were once widespread in East Asia and Siberia until the 20th century when hunting，ecological damage and increased human activities drove the birds to near extinction.
    In 1981，the entire species around the world was down to the seven crested ibises which were found only in Yangxian County，northwest China's Shaanxi Province，and deep in the Qinling Mountains，making Qinling，a natural boundary between China's north and south，the last shelter of the wild birds.
    Since 1981，the local government of Yangxian County has put forward four bans for the protection of the species，prohibiting activities including hunting in the birds' living areas，cutting down trees where they nest，using chemicals in their food-finding areas，and firing guns in their breeding（繁殖）areas.The Chinese government arranged special funds to protect the habitat of crested ibises，sealing off mountains to plant trees in the birds' living areas.China started the artificial breeding of crested ibises in 1991 and had bred more than 400 birds in Shaanxi as of last year.
    Years of constant effort have brought promising results.It is estimated that there are more than 5，000 crested ibises in the world now，and a majority of them live in Shaanxi.The bird's habitat in China has risen from less than 5 square km in 1981 to the current 15，000 square km.
    "It is lucky that the crested ibis，an ancient bird，is still flying around，" said Zan Linsen，head of the Shaanxi Academy of Forestry. "The conservation story of crested ibises not only shows us the power of ancient life，but also the necessity and urgency of ecological environment protection."

201636. （2025•铁一中学•六模） The burning of coal may be falling out of favor as a means of generating heat and electricity，but that doesn't mean it no longer has valuable uses.The team of King Abdullah University of Science and Technology （KAUST） is using coal for a new economy.
   The project is led by Associate Professor Andrea Fratalocchi.While reading about challenges of ending the use of coal in power generation，Fratalocchi was struck by a novel possible use for coal. " Why don't we use coal for seawater desalination（脱盐）？" Fratalocchi recalls，still excited.Capable of taking in sunlight，the black mineral adds to the list of substances in dark colors serving the purpose，which the team is on a long-standing hunt for.
   Fralalocchi and his team began to explore the use of a material known as carbonized compressed powder（压缩粉末），also CCP，which is created by breaking coal into powder，and then pressing that powder back into a solid that has more tiny holes—it can also be made into a desired shape.The team mixed CCP with natural cotton fibers，producing a block which was then placed within a seawater-containing container，with its bottom touching water surface.While sunlight heated the black surface of the block，the inside fibers helped water flow in and through the block from the bottom.When that liquid water reached the hot surface，it turned into steam which rose and condensed（冷凝）on the inside of a specially shaped cover.That condensation then flew down the cover and was collected as fresh，drinkable water.The seawater's salt content remained behind within the CCP.A simple wash was enough to remove most of it，so the material could be reused multiple times.
   KAUST has partnered with the Dutch start-up PERA Complexity to promote the technology.The material will see its first use in a pilot plant in Brazil. "CCP is abundant in nature and reasonable to use，besides being lightweight and highly changeable，" says team member Marcella Bonifazi." The device's desalination rate per unit of raw material is two to three times higher than that of any other solar desalination system，but it produces fresh water at around one-third the expense of current state-of-the-art technologies.

（1）What has Fratalocchi's team been seeking for？
A．Fibers functioning well with CCP.
B．Green ways to desalinate seawater.
C．New industrial applications of coal.
D．Dark-colored materials for desalination.
（2）How did the seawater get into the CCP block？
A．Through the tiny holes.
B．Through CCP.
C．Through cotton fibers.
D．Through a special cover.
（3）Which feature of CCP does Marcella Bonifazi stress？
A．Being eco-friendly.
B．Being low-cost.
C．Being efficient.
D．Being flexible.
（4）What does the text mainly talk about？
A．Drinkable water will be got from the sea.
B．CCP is expected to be in real-life use soon.
C．Coal finds new use in desalination technology.
D．Scientists have made a breakthrough in desalination.
