WEEK 15 自然环境（2）一、阅读理解（共12小题；共24分）AExplorer Robert Falcon Scott died in 1912 while crossing Antarctica, but his story lives on in artifacts(手工艺品) that continue to be discovered on the frozen continent at the bottom of the world. The most recent find: a century-old photographer's notebook at one of Scott's expedition bases in Antarctica. The notebook belonged to George Murray Levick, a surgeon and photographer who was part of Scott's 1910-13 expedition. It contains pencil notes about photos he took in 1911 at Cape Adare."It's an exciting find," said Nigel Watson, director of the Antarctic Heritage Trust. "The notebook is a missing part of the official expedition record. After spending seven years conserving Scott's last expedition building and collection, we are delighted to still be finding new artifacts."The notebook was found in January 2013 at another Scott camp, the Cape Evans base, after the summer snow melt around a building exposed it, said Paula Granger, communications manager for the trust.After so many years, the notebook's binding had dissolved(溶解), and the pages were stuck together. The trust hired Aline Leclercq, a paper conservator, to separate and clean the pages, which were digitally recorded. The remarks in the notebook refer to photos now held by the Scott Polar Research Institute. "You can match what he's written down with the pictures," Granger said.Scott was a British explorer who became famous during what historians call the heroic age of Antarctic exploration. He arrived at the South Pole in January 1912 only to discover that his rival, Norwegian explorer Roald Amundsen, had beaten him to the spot by an estimated 33 days. Scott and several teammates died in March 1912 during the return journey.The trust said Levick was a member of a group of six men called the Northern Party, which spent the summer at Cape Adare but survived the 1912 winter in a snow cave before going to Cape Evans. In December, New Zealand's Antarctic Heritage Trust reported finding 100-year-old negatives in one of Scott's huts(小屋). These photos were taken during Ernest Shackleton's 1914-17 Ross Sea Party, another failed exploration whose members were forced to live in Scott's hut after their ship blew out to sea.1. The photographer's notebook has a history of .A. 50 yearsB. 80 yearsC. 100 yearsD. 150 years2. What was George Murray Levick?A. He was a reporter.B. He was a doctor.C. He was a writer.D. He was a conservator.3. We can infer that the notebook .A. had been buried in the ice before it was discoveredB. was found by Watson at Cape Adare in 2013C. contained a lot of photos and handmade drawingsD. was in good condition when it was discovered4. Who was the earliest person to arrive at the South Pole?A. Robert Falcon Scott.B. Nigel Watson.C. Ernest Shackleton.D. Roald Amundsen.BThere have been thousands of marine species that have become extinct. Currently there are thousands of fish that are endangered and in great need of protection. The following are some.The Arcadian Redfish are found in warm waters, such as the Atlantic and Indian Ocean. These fish can live to be 50 years old. The Arcadian Redfish is endangered due to overfishing, fish pirating, and trawling(拖网捕鱼). These fish started to decrease in population in the early 1900s because of their increased popularity in the food industry.The Bluefin tuna is one animal that is high on the endangered species list. This fish has been named one of the wonders of the ocean. The reason why they are considered to be one of the marvels of the deep-sea is their potential length and weight; they can grow to be 12 feet long and weigh over 1,500 pounds! Why are these fish disappearing at alarming rates? Well, they are at risk of extinction because they are being captured for food. Over 75% of the Bluefin tuna is consumed in Japanese restaurants often by making a popular sushi.The European Eel is found in the Baltic and the Mediterranean Sea. They have a unique metamorphosis process and they change their forms over a long time period. According to , the European Eel is one of the many threatened species that are not only endangered, but critically endangered. They are not able to reproduce as quickly to keep up with their rate of elimination. The European Eel is endangered and disappearing because of parasitic disease.The whale shark is one of many endangered sharks out there. According to one source, sharks are revered as our last "living" dinosaurs. They are known as the largest fish with the potential to grow over 60 feet long and weigh over 70,000 pounds. The whale shark also has the potential to live to be over 100 years old.Although various treaties have been signed, to help save the lives of endangered ocean life, it is up to each individual to do their part to aid in saving marine animals in danger.5. Which of the following is the best title of the passage?A. The Last "Living" DinosaursB. The Endangered Ocean FishC. The Most Popular Sea FishD. The Extinct Marine Species6. The Bluefin tuna is considered to be one of the marvels of the deep-sea because of its .A. huge sizeB. strange colorC. sharp sightD. high intelligence7. We can infer that sushi is probably a .A. toyB. snackC. fishD. pill8. The underlined word "metamorphosis" means .A. reduction in populationB. elimination in sightC. change in formD. increase in weightCA few days ago, NASA posted shocking satellite pictures of the Aral Sea in Central Asia, once the fourth biggest lake on the planet, which over the past 50 years has been drained as a result of the Soviet(苏联) effort to create farms in the desert. That once-magnificent body of water, which stretched for 26,300 square miles, is now nearly dried up and disappeared. The lake began to recede(退去) after Soviet engineers began diverting(分流) Amu Darya and the Syr Darya—the region's two major rivers—to irrigate farms created in the desert in the 1950s and 1960s. Most of the water ended up being wasted along the way.But the Aral Sea is just one of several inland bodies of water across the world that are now receding greatly.In China, Poyang Lake, that nation's largest freshwater lake, also is gradually receding due to drought and water being diverted by the Three Gorges Dam. As the waters vanish, wetlands that provide winter grounds for 87 different bird species, including 98 percent of the population of Siberian cranes, face an uncertain future as a result.Meanwhile, in Iran, Lake Oroumieh, which once was among the biggest saltwater lakes on Earth, has shrunk by 80 percent over the past decade due to expanded irrigation for farms. Salt-covered rocks that were once at the bottom of the lake are now exposed on dry desert.The Dead Sea, bordered by Jordan, Israel and Palestine, is in bad shape too. Sink holes are developing around the lake, due to factors including diversion of the Jordan River for drinking water and chemical companies removing valuable minerals from the water, causing surface levels to recede by 30 to 40 percent.In California, Cachuma Lake, a major source of water for people in the Santa Barbara area, also is rapidly shrinking, due to the effects of drought and water demand. And in Hawaii, Lake Waiau has declined to only 2 percent of its normal water level over the past five years.9. Which of the following is the best title?A. Big Lakes Around the World Are Rapidly DisappearingB. The World's Once Fourth Largest Lake Nearly Dried upC. Siberian Cranes in Poyang Lake Face an Uncertain FutureD. Many Lakes in the World Face Many Serious Problems10. We can infer that the Soviet effort to create farms in the desert is a(n) .A. good ideaB. scientific decisionC. ill proposalD. successful practice11. What do you know about Poyang Lake?A. It is the largest freshwater lake in the world.B. It is a habitat of 87 different fish species.C. It has been expanded in the past ten years.D. It is home to many Siberian cranes in winter.12. Lake Oroumieh has shrunk by 80 percent over the past decade because of .A. the effect of serious droughtB. expanded farm irrigationC. dams built on the riversD. salt-covered rocks二、完形填空（共20小题；共30分）As a child, Leela Hazzah would spend her summer nights lying on the rooftop of her home in Egypt. Her father told her 13 of his childhood, when he would sleep on the same rooftop and hear lions roaring. "I used to lie there, 14 for those same sounds. But I didn't hear 15 ," Hazzah said. Hazzah's father finally got the 16 to tell his young daughter that she would not hear lions roaring because they had long gone 17 in Egypt. "That was the moment 18 I knew what I wanted to do," Hazzah said, "I 19 to hear lions roaring."Hazzah, now 35, has since devoted her life to lion 20 . While earning her master's in biology, Hazzah's 21 led her to Kenya. She lived in a tree house and began seeing firsthand the rapid 22 of African lions due to habitat loss and human-lion conflict.Hazzah spent a year living among the Maasai to 23 their relationship with lions. "Maasai have a 24 attitude towards lions. It's a love-and-hate relationship," Hazzah said, "They 25 lions because they eat their sheep, but they also admire them 26 because they are just beautiful and wonderful animals."Now Hazzah has found one 27 to help the lion population grow. She employs 65 Lion Guardians throughout East Africa. Their 28 goal is to reduce lion killings. Her organization turns lion killers into lion protectors.The guardians are taught a number of methods to 29 human-lion conflicts in their communities. If a guardian hears about a lion hunt, he will 30 . Guardians also help farmers strengthen corrals(畜栏) where they keep their sheep.For Hazzah, watching the 31 of young Maasai lion killers has been one of the most32 parts of her efforts.

However, household waste is a major contributor to our planet's waste problem. Like it or not, it needs to be managed if we are to have a brighter green future.When it comes to being responsible for our own rubbish, the best way to approach it is by following the three golden rules of waste management, or the "3 Rs"—Reduce, Reuse and Recycle."The order is important. 34. ," says Eugene Tay, Director of Green Future Solutions in Singapore, "Recycling still affects the environment and should be done last after reduce and reuse."But, when our efforts to reduce and reuse still result in an overflowing rubbish bin, the advantages of recycling cannot be ignored. "35. ," says Amy Ho, Managing Director of World Wide Fund For Nature in Singapore, "The damage to our environment could then be slowed down as a result."In fact, by recycling just one plastic bottle, you are saving not just the material to make a new one, but you also stop it from getting thrown into a landfill(垃圾掩埋场) for up to 700 years—and that's before it even starts to rot, 36. .Recycling is so important that we really have no excuse not to do the simplest of household tasks that will make a difference."37. ," says Ho, "Starting with recycling grey water for gardening purposes, to recycling materials such as glass, paper and iron—it all reduces the use of raw materials."A. We put it in the bin and don't think too far beyond thatB. The collective action of individuals can make a significant effectC. It's important for every household to make good use of grey waterD. Waste reduction and reuse is usually the best way to decrease wasteE. The three rules of waste management should be followed by every householdF.

八年级生物与生态环境英语阅读理解25题1<背景文章>The tropical rainforest is one of the most diverse and complex ecosystems on our planet. It is a world filled with an astonishing variety of plants and animals.Plants in the tropical rainforest are highly adapted to the warm and humid environment. For example, the large and broad - leaved trees, such as the kapok tree. It can grow extremely tall, reaching towards the sunlight above the thick canopy of the forest. Its trunk is thick and strong, providing support for its large branches. The leaves are large to capture as much sunlight as possible for photosynthesis. There are also countless vines and epiphytes. Vines climb up the tall trees, using them as support to reach sunlight. Epiphytes, like orchids, grow on the branches of other plants instead of in the soil. They get water and nutrients from the air and rain.The animal life in the tropical rainforest is equally diverse. There are colorful birds, such as the toucan. The toucan has a large, brightly colored beak which is not only used for eating fruits but also for attracting mates. Monkeys are also common inhabitants. They are highly agile, swinging from tree to tree. They mainly feed on fruits, nuts and small insects. Insects are in abundance here too. Butterflies with their beautiful wings flit amongthe flowers. Some insects, like ants, live in large colonies and have complex social structures.The relationships between these organisms are intricate. For instance, many plants rely on animals for pollination and seed dispersal. Bees and butterflies pollinate flowers as they move from one to another in search of nectar. Fruit - eating animals like monkeys help to spread the seeds of plants far and wide.The tropical rainforest ecosystem is of vital importance. It is often called the "lungs of the earth" because it absorbs a large amount of carbon dioxide and releases oxygen through photosynthesis. It also helps to regulate the earth's climate. In addition, it is a huge reservoir of biodiversity, providing a home for countless species. Losing the tropical rainforest would mean the loss of many unique plants and animals, and would havea far - reaching impact on the global environment.1. What is a characteristic of the kapok tree in the tropical rainforest?A. It has small leaves.B. It is short.C. It has a thick and strong trunk.D. It grows in cold areas.答案：C。

八年级自然环境问题英语阅读理解30题1<背景文章>Deforestation is a major environmental issue that has far-reaching consequences. The main reasons for deforestation are urbanization, agricultural expansion, and logging for timber. As cities grow and populations increase, more land is needed for housing and infrastructure. This leads to the clearing of forests to make way for new developments. Agricultural expansion also plays a significant role. Farmers often clear forests to create more land for crops or grazing. Additionally, logging companies cut down trees for timber, which is used in construction and furniture making.The impacts of deforestation are numerous. It leads to loss of biodiversity as many species lose their habitats. This can disrupt ecosystems and lead to the extinction of some species. Deforestation also contributes to climate change. Trees absorb carbon dioxide and release oxygen. When they are cut down, less carbon is absorbed, and more carbon dioxide is released into the atmosphere. This can lead to global warming. Moreover, deforestation can cause soil erosion as the roots of trees that hold the soil in place are removed.To address deforestation, several measures can be taken.Governments can implement laws and regulations to limit logging and protect forests. They can also encourage sustainable agriculture and urban planning. Reforestation efforts can be undertaken to replant trees in areas that have been deforested. Additionally, individuals can make a difference by reducing their consumption of products that contribute to deforestation, such as paper and furniture made from unsustainable sources.1. The main reasons for deforestation do not include ___.A. urbanizationB. industrializationC. agricultural expansionD. logging for timber答案：B。

Week Fifteen 自然环境一、阅读理解（共20小题；共40.0分）ADespite recent storms during the autumn and first part of the winter, drought conditions are forecast to continue over a large part of the Plains.Rainfall has been enough over the Ohio and lower Mississippi basins. However, unless there is a big turn later this winter and spring, more important problems could be ahead for the Mississippi River above the Ohio River connection.While a storm is forecast to swing northeastward over the Central states, much of the rain may fall south and east of St. Louis. Mississippi River levels are expected to dip again next week at St. Louis.Engineers has been taking steps to keep the shipping channel open by digging the river bottom, removing rocks and placing barriers under the water to reduce shifting soil. The rest is up to Mother Nature. Barge companies have been limiting their loads due to the low water levels.Snow fell over part of the winter wheat belt with the storm just after Christmas 2012. However, much more moisture is needed through the winter and into the spring.According to Dale Mohler, "One of the big problems the Central states had last spring was a lack of thunderstorms". These groups of thunderstorms are the major source for spring rainfall and runoff over the Plains and Midwest, following melting snow early."There are concerns for drought continuing over the central High Plains and the northern Plains in general going into the spring," Pastelok stated that the pattern does not look to be as dry of a start this spring, when compared to last year from Iowa to the Ohio Valley and some moisture is likely to make appearances over the southern Plains.There is also some good news for the Southeast. "Signs are that the drought—abnormally dry areas over Georgia and the Carolinas will shrink moving through the winter and should be mostly gone by the spring," Pastelok said.1. Which place is still facing the serious drought?A. The central High Plains.B. Lower Mississippi basins.C. Over the Ohio River.D. Areas over Georgia.2. By saying "the rest is up to mother nature", the writer means .A. the rest is to deal with natureB. the rest is at the mercy of natureC. the rest will be in control of natureD. the rest are busy conquering nature3. What role do the thunderstorms play in the central states?A. They will flood these states in summer.B. They will cause snow to melt early in spring.C. They will bring a lot of rainfall there.D. They will get these states to become dry.4. Patelok's attitude to the drought in the Southeast was .A. doubtfulB. disappointedC. concernedD. optimistic5. What might be the most suitable title for the passage?A. Drought Continues in Spite of Recent Storms in AmericaB. America Suffered the Most serious Drought in HistoryC. Many Southern States in America Are Facing DroughtD. More Storms will Solve the Drought Problem in AmericaBThe bad reputation icebergs sometimes have isn't entirely deserved—even if the scientists who study these floating islands of ice are the first to admit just how risky they can be. Thesesame experts are learning more about how helpful icebergs can be for life too.Icebergs, scientists are discovering, play host to all kinds of life—everything from tiny organisms called phytoplankton to huge whales.Finding how and why animals choose to make their homes in and around icebergs hasn't proven an easy task for scientists. Icebergs rise to towering heights and even more terrible depths. To study them underwater, scientists may sink scientific instruments hundreds of meters to the chilly seafloor. To understand what's going on dozens of meters up on top, these experts may depend on remote-controlled aircraft. Meanwhile, waves may rock and wet scientists waving in nearby boats.The biologists Ken Smith and Ron Kaufmann have sailed through the waters that surround Antarctica to get up close with icebergs. No matter how curious the researchers may be, they do most of their admiring from afar."When an iceberg breaks off from an ice sheet, the last place you want to be is anywhere near it," says Kaufmann. "A lot of icebergs are cracked, and huge sheets can come off at any time," adds Smith. "They can drop a huge piece of ice into the water, and the problem is that it creates a huge wave, which could flood your ship."The planet is warming. As a result, the ice is melting. More melting means more icebergs calve from the edges of the ice sheets where they meet the ocean. Melting icebergs don't just let go huge quantities of freshwater into the ocean—they also deliver a lot of the fertilizer that phytoplankton need.Importantly, tiny phytoplankton provide much more than dinner. They also consume carbon dioxide—about as much as do all the plants on land.So more global warming could mean more icebergs. And more icebergs could mean more phytoplankton. In turn, more phytoplankton may lead to less carbon dioxide in Earth's air and water.Will iceberg communities help slow the rate at which global temperatures are rising? It's still unclear.6. The third paragraph is mainly about .A. the difficulty of studying icebergsB. the method of studying icebergsC. the benefits of studying icebergsD. the scientific equipment of studying icebergs7. From what Kaufmann said, we can infer that .A. the nearer to the icebergs, the safer it isB. it is very dangerous to get close to icebergsC. icebergs are the last place people never land onD. an ice sheet can form into many icebergs8. The underlined word "calve" may mean .A. cut offB. fall offC. break offD. put off9. What is the final result of more icebergs?A. They may increase the amount of carbon dioxide.B. They become shelter for phytoplankton.C. They provide food for various organisms.D. They may slow the speed of global warming.10. The passage mainly tells us that .A. icebergs host large and lively communities of lifeB. icebergs are a threat to the safety of sailingC. icebergs are floating across oceans slowlyD. icebergs are home to many sea animalsCVisit the beach on a hot afternoon and you may not realize it, but someone—or rather something—is watching from above. If you stand in the right place, the silent watcher's unseen spotlight will pass right over you, like the spotlight of a police airplane flying overhead.Scientists these days are worried about sea level. As Earth warms, the surface of the ocean is rising upward. This rise is happening partly because salt water increases a tiny bit as it warms. "Warmer water exactly is taller," explains Josh Willis.Sea level also is rising because warm temperatures have prompted glaciers in Antarctica, Greenland and other usually cold places to melt more quickly. Glaciers are essentially rivers of ice, and their melting adds freshwater to the ocean. Antarctica and Greenland are together losing about 350 cubic kilometers of ice per year—enough melt-water to fill up 80,000 baseball stadiums. Spread over the world's oceans, that melt-water alone raises sea level about 1 millimeter or so each year.Scientists have long known that sea level changes over time. Paul Hearty, a geologist, has found stones covered in shells some 30 meters above sea level. Those high and dry barnacles are several million years old. They serve as evidence that sea level was once much higher.Sea level has risen and fallen with the ice ages, over hundreds of thousands of years. During past ice ages, oceans were lower because more water was tied up in glaciers on land. But between ice ages, sea level sometimes rose higher than it is today, as melting glaciers sweated their water into the ocean.The big challenge for scientists has been how to measure changes to sea level throughout the past 50 to 100 years. Bruce Douglas, a retired scientist spent years working on this. During the 1980s and 1990s he measured sea level rise by studying records from tide gauges. Harbor operators have relied on these devices for more than 200 years to watch the water level in coastal areas in order to warn ships of running aground. But the gauges measured the level of the world's oceans, which cover 360 million square kilometers, in only 20 or 30 places!11. The second paragraph implies that .A. water level is lower if it is frozenB. salt water is easier to become warmC. the surface of the ocean is reducingD. the ocean is becoming smaller in size12. From the third paragraph we know that .A. Antarctica has the largest amount of ice in the worldB. the melting of glaciers causes sea-level to riseC. ice from Greenland raises sea level about 1 millimeterD. 80,000 baseball stadiums are flooded by sea water13. During the ice ages oceans were lower because .A. more water was frozen into ice in the seaB. glaciers provided more water into the oceanC. more water was left on land as iceD. water couldn't flow easily in cold weather14. Why did harbor operator record tide gauges?A. To learn more about the changes of tides.B. To prevent the coastal areas being flooded.C. To measure the level of the world's oceans.D. To warn ships not to run aground.15. What might be the most suitable title for the passage?A. Watching Our Sea Level RiseB. Measuring the Ocean LevelC. Changing the Sea LevelD. Studying the World SeasDThe United States Environmental Protection Agency says only seven percent of plastic waste in the United States is recycled each year. A new company in northern New York says it can increase that percentage. It also says it can help the United States reduce the amount of oil it imports.The company has a machine it calls the "plastic-eating monster". Every hour, thousands of kilograms of milk jugs, water bottles, and grocery bags are fed into the machine. The plastic waste comes from landfills across the United States. John Bordnyniuk runs the company, called JBI. "Basically they've been mining their own piles for us and sending them here."Eight percent of the recycled plastic is used to run the system. Independent testers say eighty-six percent of what goes in comes out as fuel.Bob Molodynia helps run the company. He watches as the plastic-eating machine pours a thin, brown liquid into an oil barrel."You could tap this right now and this is ready to go. That's a number six fuel, that's what a lot of like US Steel uses, a lot of major companies, that's what they pay the big bucks for, right there."JBI produces several thousand liters of fuel a day. It creates different grades of fuel for different industries. It sells the fuel for up to one hundred dollars a barrel. Each barrel costs about ten dollars to produce.John Bordyniuk believes plastics will become an important source of fuel for the United States. He says this will reduce the country's dependence on foreign oil and reduce the amount of plastic waste in its landfills.Scientists say plastic-to-oil technology is still new and developing. They say it is not yet known if the process is environmentally friendly. And some questions whether turning plastic into oil can even be considered "recycling".Carson Maxted is with the publication Resource Recycling, a magazine that reports on the plastic recycling industry. He says because there is a lot of plastic waste and a great demand for oil, JBI's recycling technology may create great changes in both industries."So they're getting value from something that would otherwise go to the landfill, things that wouldn't be accepted into a recycler."16. How did John's JBI get plastic waste?A. It was posted to the company by people.B. John sent his workers to collect it.C. The company minded landfills itself.D. It was sent by landfills themselves.17. According to the passage, plastic-to-oil technology is .A. effectiveB. wastefulC. simpleD. environmentally friendly18. From what Bob said, we can infer that the JBI's oil is .A. very expensiveB. of high qualityC. too thin to useD. black in color19. The attitude of Carson towards John's technology is .A. doubtfulB. negativeC. supportiveD. unconcerned20. What would be the best title for the passage may be .A. Can Oil Be used to Reduce the Amount of Plastic Waste?B. Can You Make A Lot of Money from Waste Plastic?C. Can Oil be Made from Waste Plastic?D. Can Waste Plastic Reduce Our Need for Oil?二、完形填空（共20小题；共30.0分）New Australian research shows coral reefs aren't seriously damaged by ocean acidification(酸化) than first thought.

But a study on the Great Barrier Reef suggests otherwise.Among the threat to 23 from the effects of climate change, pollution and overfishing, Australian researchers have found some unusual 24 news.A team has been 25 coralline algae (珊瑚藻), which are plants that26 like a paste strongly to 27 coral. A new study has found that dolomite (白云石), a mineral, helps to 28 reefs from rising ocean acidity,which is caused by the 29 of carbon dioxide from the atmosphere.Lead author Merinda Nash says it is an important 30 .

八年级环境问题英语阅读理解25题1<背景文章>Global warming is one of the most serious environmental issues facing our planet. It is caused by a variety of factors. The burning of fossil fuels such as coal, oil, and gas releases large amounts of greenhouse gases into the atmosphere. Deforestation also contributes to global warming as trees absorb carbon dioxide.The effects of global warming are far-reaching. Rising sea levels threaten coastal areas and low-lying islands. More frequent and intense heatwaves, storms, and floods can cause damage to property and endanger lives. Changes in weather patterns can also affect agriculture and food production.To address global warming, we need to take action. We can reduce our carbon footprint by using energy-efficient appliances, driving less, and using public transportation. We can also support renewable energy sources such as solar and wind power. Planting trees can help absorb carbon dioxide and reduce the amount of greenhouse gases in the atmosphere.1. What is one of the main causes of global warming?A. Planting more trees.B. Using renewable energy sources.C. Burning fossil fuels.D. Reducing carbon footprint.答案：C。

WEEK 15 自然环境（2）一、完形填空（共20小题；共35分）AToo hot? Some mountains offer climate animals lots of land. Pikas(兔鼠) like living there. When it gets warm, they like 1 uphill. They look for cooler environments they like better. And pikas aren't alone. A 2011 study found that many mountain 2 move their living place. They move uphill by about 11 meters every ten years since the 1960s.Scientists think this would be 3 news for the animals. For one, the higher up a mountain they travel, the 4 space that they can live in. After all, mountains look like pyramids, right?In many 5 , animals like pikas and birds may actually get ground when they move uphill, the study shows. Paul Elsen is a scientist. His team published its 6 on May 18 in Nature Climate Change.Most scientists thought that higher living place for migrating(迁移) animals became 7 and smaller. If it is true, that would mean that many earth-warming animals might run out of their new living place—and face 8 . But Elsen started to doubt about this while he was studying 9 in the Himalayas. "That's a huge mountain area in East Asia. Such mountain area might actually 10 more living place to some animals that like living in cooler environments," he said.1. A. playing B. living C. working D. eating2. A. animals B. plants C. people D. flowers3. A. good B. bad C. short D. long4. A. more B. much C. little D. less5.

A. maths B. rivers C. cars D. birds10. A. offer B. provide C. send D. takeBScientists in the UK are surprised that so many flowers are in bloom(开花期) this winter. They said that in usual years, between 20 and 30 kinds of flowers and plants are open. However, on New Year's Day, scientists found 368 different kinds in bloom.Scientists believe so many flowers are in bloom because of climate change (气候变化). Last year was the warmest year Britain has ever had. Dr. Tim Rich told the BBC about his surprising at the number of flowers he saw at the start of this year. He said, "Fifty years ago, it was difficult to find plants in winter. But it seems everything's becoming different." He said some flowers were in bloom five months earlier.Scientist Rich explained how the weather affects flowers. The flowers are usually killed by the cold in December. He said, "We are now in our fourth warm winter. Usually flowers go away by Christmas but this year it hasn't happened." He added, "But many flowers are still in bloom now, after New Year's Day."Britain's weather report talked about the climate for last year. It said, "All months except August were warmer than usual years, and this was the warmest year on record for the UK. It was also wetter than usual years for many areas."11.

Special Flowers in the UKC. Flowers on New Year's DayD. Hot Weather This YearCThe most unusual bird in the world is looking for a new home with lots of wetland and lots of food! There are only a few red-brown pochards (红头潜鸭) in Madagascar. People thought the bird died out after they last saw it in 1991, but they found it again in 2009.A new study showed that 96 percent of the small wild chicks are dying between two and three weeks old, and scientists believe most of them die because they have nothing to eat.Cutting down trees, fishing, and farming have made the bird move to another lake. Sadly, this lake is very, very deep. Young birds are too hungry because their parents can't go down deep enough into to the water to get food for them.The last home of the pochard is one of the cleanest wetlands in the country, but it's simply too small for the pochard. The scientists in the wetland watched 10 or 11 parent pochards hatch(产卵). They found some chicks would die.The birds could live in the wild again if they can find a new home. Dr. Hilton works in the wetland. He said they had found a lake that could be a great new home for the ducks."We should work with the villagers to keep the pochard safe. We must also try to keep the lake clean and help people to get a better life from the lake they live around. We should all take part in the work," he said.16. How long didn't people see red-brown pochard?A. About ten years.B. About twenty years.C. About thirty years.D. About forty years.17. Why do most baby red-brown pochard die between two and three weeks?A. Because they have nothing to eat.B. Because they have nothing to drink.C. Because their mothers don't like them.D. Because their fathers don't like them.18. The lake is so that mother pochard can't get food for their babies.A. dirtyB. littleC. deepD. hot19. What do the scientists think of the last home of the pochard?A. Big enough.B. Too dirty.C. Too deep.D. Too small.20. The last paragraph mainly tells us that .A. we must work with the villagers to keep the pochard safeB. we must also try to keep the lake clean for the pochardC. we must help people to get a better life from the lakeD. the birds can live in the wild if they can find a new home二、阅读理解（共5小题；共10分）If you are in the northern half of the earth and above the tropics(热带), have you noticed that the sun is rising earlier every day? It shows that spring is here and days are getting longer.If you are in the US and in a state that keeps Daylight Savings time (DST 夏时制), the clocks have been moved one hour ahead on March 8. DST is the ritual(仪式) we jump over one full hour of a Sunday in March, when clocks get reset to 2 a.m. at the usual 1 a.m.!The idea came from Benjamin Franklin! While serving as US ambassador(大使) to France in 1784, Franklin woke up at 6 a.m. to find the sun up really early. He thought that if everyone were up an hour earlier, people could save a lot on the cost of candles. Meanwhile in the late 1800s, George, from New Zealand, suggested changing the clock during summers instead of springs. More daylight in the evenings helped people do much work.It was in 1917 that DST was accepted in Europe and America. During World War I, the West realized that to save oil and keep factories producing, it helped to have more hours of daylight.To make it similar in different areas that accepted DST and those that did not, the US government declared(宣布) a DST standard(标准) in 1966. Nowadays clocks are reset forward on the second Sunday in March and fall back on the first Sunday in November.21. What is the first sign that spring is coming?A. The sun is rising earlier.B. The sun is rising later.C. The sun rises in the east.D. The sun goes down in the west.22. The underlined word "reset" means " " in Chinese.A. 重新设置B. 取消设置C. 错误设置D. 定位设置23. Benjamin Franklin came up with the idea of DST in order to .A. save timeB. save foodC. save moneyD. save light24. When was DST accepted in Europe and America?A. In 1784.B. In the 1800s.C. In 1966.D. In 1917.25. How long does Daylight Savings time keep in a year in the USA?A. About six months.B. About seven months.C. About eight months.D. About nine months.三、阅读与表达(问答式)（共5小题；共10分）This is a good-news story about sea life. Scientists have reported that there are more blue whales(鲸鱼) in the eastern Pacific Ocean. Scientists report that there are now over 2,200 blue whales between Mexico and Alaska.Humans killed nearly all the blue whales in that area(地区) and the blue whales were close to extinction(灭绝). Killing whales was against rules in 1971 and the numbers of the world's largest animal started going up. It has taken over 40 years for the blue whale to recover. Dr. Cole Monnahan was very happy at this news. He said, "For us, this is a great story."Dr. Monnahan said the number of 2,200 blue whales in the area might not rise any more. He said, "Before this study, some people thought that number should be going up, but if there are about 2,200 whales now, it's the biggest number our environment can help."Monnahan warned that we should still protect the animal, saying, "California blue whales are recovering(恢复) because we have tried our best to stop killing them. If we hadn't, the number would have been gone down." He added that, "The recovery of California blue whales from whaling shows that we can save blue whales if we try our best. It's time for us humans to do something helpful."根据短文内容，完成下列小题。

八年级环境与生态英语阅读理解25题1<背景文章>Forests are of great importance to our planet. They provide a home for countless species of plants and animals. The trees in forests help to purify the air by absorbing carbon dioxide and releasing oxygen. They also play a crucial role in regulating the climate.However, forests are facing many threats. Deforestation is a major problem. People cut down trees for various reasons, such as to make room for agriculture, build houses, and produce paper and other products. This leads to the loss of habitats for many species and can cause soil erosion and changes in the climate.To protect forests, we need to take action. We can reduce our consumption of paper and wood products. We can also support organizations that work to protect forests and promote sustainable forestry practices.Forests are not only important for the environment but also for our economy. Many people depend on forests for their livelihoods, such as loggers, hunters, and tour guides. By protecting forests, we can ensure that these people continue to have a source of income.In conclusion, forests are a vital part of our world. We must doeverything we can to protect them for future generations.1. Forests are important because they ___.A. provide food for peopleB. purify the airC. are beautifulD. are easy to cut down答案：B。

八年级英语环境保护主题阅读练习题30题1<背景文章>Forests are of great importance for environmental protection. They play crucial roles in maintaining soil and water conservation. The roots of trees hold the soil firmly in place, preventing erosion. When it rains, forests help to slow down the flow of water and filter it, reducing the risk of floods.Moreover, forests are a major source of oxygen. They absorb carbon dioxide and release oxygen through the process of photosynthesis. This is essential for the survival of all living beings on Earth.In addition, forests maintain ecological balance. They provide habitats for a wide variety of plants and animals. Different species depend on each other for survival. For example, some birds build their nests in trees, while small animals find food and shelter in the forest.Forests also have economic value. They provide timber for construction and paper production. However, we must ensure sustainable use of forest resources to avoid overexploitation.Protecting forests is everyone's responsibility. We can start by reducing waste, recycling materials, and using less paper. We can also support organizations that work towards forest conservation.1. Forests play an important role in ___.A. air pollutionB. soil and water conservationC. noise pollutionD. light pollution答案：B。
