One million plastic drinking bottles are thrown away every minute. What if we could use plastic waste to build roads? This is exactly what Toby McCartney has done.In 2019, McCartney’s UK-based company, MacRebur, built a plastic road in Elgin town, Scotland. The plastic waste was made into grains（颗粒）and then mixed with bitumen(沥青). The road looks just like any other road. But it has improved strength and is more stretchy(有弹性的) thanks to the plastic.“Our technology can not only help solve the problem of plastic waste but also produce roads that deal better with changes in the weather,” McCartney said.McCartney’s idea came from a trip to India. “I saw people in India would put plastic waste into potholes(路面的坑洼) and burn it. The plastic would melt down(熔化) and fill the holes,” said McCartney.“I knew that there must be some correspondences between plastic and bitumen, which both come from oil. That’s how I started to think about mixing them,” he said.After lots of testing, McCartney found the perfect method. And now his company has built many plastic roads around the world. A one-kilometer stretch of road uses about 684, 000 plastic bottles or 1.8 million plastic bags. The road itself can be recycled and the materials can be reused to build new roads.“We’re just a small part of ending the plastic problems, but it’s nice to be part of it,” McCartney said. “I just don’t want my daughters to live in a world where there are more plastics in the ocean than fish.”21．Compared with normal roads, the plastic road _________.a. is not easy to breakb. is fit for hot weatherc. is more stretchyd. costs more moneyA．ab B．ac C．bc D．bd22．________ gave McCartney the idea of building the plastic road.A．Too many changes in the weatherB．His wish to reduce plastic pollutionC．His knowledge of plastic and bitumenD．Indian people’s way of dealing with potholes23．The underlined word “correspondences” in this passage means ________.A．competitions B．connections C．differences D．reasons24．What does McCartney mean in the last paragraph?A．He is ready to offer help in reducing plastic pollution.B．Children should also join to reduce plastic pollution.C．Plastic problems will soon be solved with his help.D．Plastic pollution is becoming more and more serious.25．What is the main idea of the passage?A．To describe how much a kid’s future matters.B．To encourage every company to build a plastic road.C．To help people understand how harmful plastic waste is.D．To tell people plastic waste can be reused to build a road.05（2022·江苏宿迁·三模）Fairfield School is called “the greenest school in Britain” because the pupils and the teachers at the school think it’s very important to look after the environment. ____26____ Growing vegetablesThe pupils in Fairfield School started their own vegetable garden.

英语阅读WeekFifteen自然环境
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.

八年级生物学与自然环境英语阅读理解25题
八年级生物学与自然环境英语阅读理解25题1<背景文章>Forests are one of the most important ecosystems on our planet. A forest ecosystem is composed of various elements. Firstly, there are different kinds of trees. These trees can be coniferous trees like pine trees, which are often tall and have needle - like leaves, or deciduous trees such as oak trees that lose their leaves seasonally. The forest floor is also a crucial part. It is covered with fallen leaves, twigs, and other organic matter. This layer is rich in nutrients as the decomposed materials return nutrients to the soil.In addition to plants, there is a great deal of animal life in the forest. There are small mammals like squirrels that scurry around collecting nuts and building nests in the trees. Birds of various species also make their homes in the forest. Some birds, like woodpeckers, use their strong beaks to peck at the tree trunks in search of insects. There are also larger animals such as deer that graze on the plants in the forest.The biodiversity in the forest is extremely high. There are countless species of plants, animals, and microorganisms living together. Each species plays a unique role in the ecosystem. For example, some plants may provide food for certain animals, while some animals help in thedispersal of seeds.The ecological functions of the forest are numerous. Forests play a significant role in maintaining the water cycle. The trees absorb water from the soil through their roots and release it into the atmosphere through transpiration. This helps in the formation of clouds and subsequent rainfall. Forests also act as carbon sinks. They absorb a large amount of carbon dioxide from the atmosphere, which helps to mitigate the effects of global warming. Moreover, the forest soil helps in preventing soil erosion. The roots of the trees hold the soil firmly in place.However, forests are facing numerous threats today. Deforestation is one of the major problems. People cut down trees for various reasons, such as to make space for agriculture, to obtain timber for construction and furniture - making. Another threat is forest fires. Some forest fires are caused by natural factors like lightning strikes, but many are due to human activities such as careless camping or illegal burning. Pollution also affects the forest ecosystem. Air pollution can harm the leaves of the trees, reducing their ability to photosynthesize, and water pollution can contaminate the soil and water sources in the forest.1. What are the two main types of trees mentioned in the forest ecosystem?A. Apple trees and banana trees.B. Pine trees and oak trees.C. Palm trees and willow trees.D. Cherry trees and maple trees.答案：B。

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.

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 YearThe 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.

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。
