高三英语阅读理解题训练及答案详解

高三英语阅读理解题训练及答案详解第一篇:Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might bedifficult to imagine anything twice as big.All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags,bottles and containers—plastic products of all kinds.The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert,with light winds and slow moving water currents. The water moves so slow that garbage from all over the world collects there.In recent years,there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste,resulting in death or injury. Even more die from a lack of food or water after swallowing pieces ofplastic. The trash can also make animals feel full,lessening their desire to eat or drink.The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste,and from eating fish that swallowed waste. Divers can also get trapped in the plastic.Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier,another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.In August,2009,a team from the University of California,San Diego became thelatest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effec t on ocean environment.51.How did the writer introduce the topic of the passage?A. By giving an example.B. By listing the facts.C. By telling a story.D. By giving a parison.52.What do we know about the Great Pacific Ocean Garbage Patch?A. It is made up of various kinds of plastic products.B. It is a solid mass of floating waste materials.C. It lies l60 000 kilometers east of California.D. It is described as a kind of oceanic desert.53.Why do people pay attention to the Great Pacific Ocean Garbage Patch?A. Because it may prevent the flow of ocean water.B. Because the polluted plastic articles will move up the food chain.C. Because it may be from an island in the pacific.D. Because ships may be trapped in the floating waste.54.Which column can you find the passage on a newspaper?A. Sports and entertainment.B. Media and culture.C. Environment and society.D. Science and technology.55.The purpose of writing this passage isto____________.A. warn people of the danger to travel in the pacificB. analyze what caused the waste patch in the pacificC. give advice on how to recycle waste in the oceanD. introduce the Great Pacific Ocean Garbage Patch第二篇:Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway.WHO spokesman Daniel Epstein said the microscopic(微小的) ash is potentially dangerous for people when it starts to reach the Earth because inhaled(吸入) particles can enter the lungs and cause respiratory problems. And he also said Europeans who go outside might want to consider wearing a mask.Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were "hysterical." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder. During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation even in healthy people. But once it falls from a greater distance — like from the cloud currently hovering above Europe — its health effects are often minimal, experts say."Not all particles are created equal," said Ken Donaldson, a professor of respiratory toxicology at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be negligible and that only those in the near districts of the Icelandic volcano would likely be at risk.Dr. Stephen Spiro, a professor of respiratory medicine and deputy chair of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical."60. The text is mainly about .A. the effect of volcanic ashB. the health risk of volcanic ashC. the disadvantages of volcanic ashD. the opinions on health risk of volcanic ash61. Which one is true according to Paragraph3?A. The volcanic ash’s effects on Europeans were little.B. The ash caused irritation even in healthy people.C. Other experts thought WTO’S warnings were useful.D. The volcanic ash was more dangerous than cigarette smoke or pollution.62. The underlined word “hysterical” in Paragraph4 most probably means .A. amazingB. practicalC. valuableD. overstated63. What can we learn from the passage?A. The volcanic ash wouldn’t be harmful to people.B. All experts thought the volcanic ash did great harm to our health.C. People close to the volcano would likely be at risk according to some experts.D. Europeans should stay indoors because Iceland's volcano starts settling.第一篇:51.D。

备战高考英语 阅读理解综合试题附答案解析

一、高中英语阅读理解1.阅读理解Most adults find it hard to recall events from their first few years of life and now scientists have found exactly when these childhood memories fade(消失).A new study has found that most three-year-olds can recall a lot of what happened to them over a year earlier, and these memories persist while they are five and six, but by the time they are over seven, these memories decline(衰退) rapidly.Most children by the age of eight or nine can only recall 35% of their experiences from under the age of three, according to the new findings.The scientists behind the research say this is because at around this age the way we form memories begins to change. They say that before the age of seven children do not have a sense of time and place in their memories. In older children, however, the early events they can recall tend to be more adult-like in the way they are formed. Children also have a far faster rate of forgetting than adults. The findings also help to explain why children can often have clear memories of events but then forget them just a couple of years later.The youngsters first visited the laboratory at the age of three and discussed six unique events from their past, such as family outings, trips to the zoo, and the first day of school. The children then returned for a second session between the ages of five and nine to discuss the same events. The researchers found that between the ages of five and seven, the amount of memories the children could recall remained between 63 -72 percent. However, the amount of information eight-to nine-year-old children could recall dropped to 35 and 36 percent.(1)What does the new study tell us?A.Childhood memories decline with years.B.Three-year-old kids are the cleverest.C.Childhood memories can fade easily.D.Some adults cannot recall past events.(2)What does the underlined word "persist" in Paragraph 2 mean?A.Change.B.Remain.C.Appear.D.Return.(3)What can we learn from Paragraph 4?A.Adults cannot have clear memories of past events.B.Children can think like adults when they get older.C.Children under 7 years old have different ways of forming memories.D.Children often forget things because they have no idea of time or place.(4)In the second session, nine-year-old children _________.A.refused to discuss the same eventsB.remembered all their family outingsC.could recall 72 percent of their past eventsD.only remembered a small part of their past events【答案】(1)A(2)B(3)D(4)D【解析】【分析】本文是一篇说明文,介绍了记忆消失的一些知识。

2024届全国高考(新高考)英语复习历年真题好题专项(阅读理解+读后续写)练习(附答案)

2024届全国高考(新高考)英语复习历年真题好题专项(阅读理解+读后续写)练习Ⅰ.阅读理解A2023ꞏ济南市高三检测说明文258词★★★☆☆The AIDA model is the foundation of modern marketing and advertising practice. It outlines the four basic steps used to persuade potentials to make a purchase. The first three steps lie in creating attention (A), decorating interest (I), and building desire (D) for the product, before the fourth step—the “call to action” (A)—tells them exactly how and where to buy. AIDA can channel the customer's feelings through each stage toward reaching a sale.Attracting the customer's attention is the first challenge and this may be achieved by using an attracting phrase or picture. Once someone's attention has been clutched,__it must be turned into real interest. This is best done by providing a brief description of the product's benefits to the consumer rather than simply listing the product's main features or problem-solving claims.Now, it is time to transform that interest into a desire for a product or service. This is where consumers need to believe their lives could be better by possessing the product. It could be a vital step towards turning a potential into a real customer.“Call-to-action” is where all of the initial hard work pays off and leads to the action from a potential customer. For example, they might pick up the phone to discuss the idea of a trial of the services or, alternatively, they may just buy that product or service that has been promoted to them all along.And AIDA is used to great effect in the movie industry. Movie studios begin their marketing campaigns months in advance. The campaigns develop by offering attractive flashes of the movie without giving too much away. Desire is inspired by the release of the full preview which is fully designed to show the exciting moments of the movie, from special effects to humorous lines of dialogue on the opening weekend. Advertisements in newspapers and on television focus on the movie's release, inviting the consumer to go and buy a ticket.1.What is the purpose of practising AIDA?A.To create jobs.B.To increase sales.C.To research markets.D.To introduce products.2.What does the underlined word “clutched” mean in Paragraph 2?A.Seized. B.Freed.C.Cheated. D.Affected.3.In which stage of the AIDA model may a customer call to try the service?A.Action. B.Interest.C.Desire. D.Attention.4.Why does the author mention the movie industry in the last paragraph?A.To design an AIDA model.B.To display how AIDA works.C.To show how to make a movie.D.To advertise the movie industry.B2023ꞏ济南市高三检测议论文349词★★★☆☆According to a study done by University of Michigan, shopping to reduce stress was 40 times more effective at giving people a sense of control and shoppers were three times less sad than those only looking at items.More than half of the 1,000 consumers surveyed by Credit Karma, head researcher of the study, said they have shopped to deal with feelings of stress or depression. About 48 percent of men and 31 percent of women who have stress shopping said they had purchased alcohol when stressed. About 82 percent of women spend on clothing compared to 52 percent of men. Women also lead shopping for jewellery, 42 percent, compared to 22 percent for men.In some sense, stress shopping can actually help you live a healthier life by making sure that your blood pressure is lowered. The survey found 82 percent had only positive feelings about their purchases and that the positive mood was long-lasting. However, stress shopping, for many, could grow into a drive that uses up money, causes conflict, and therefore adds great stress to life.Despite the in-time joy from purchases, stress shopping never proves a long-lasting cure to stress or depression. Actually it needs to be avoided anyhow. Whether you're purchasing presents or buying groceries, having the items you need written down will provide you with brightness while shopping. Reward yourself for sticking to your list and you'll be more likely to commit to it.In addition always think about what you struggle with most financially. Do you spend too much money at the mall? Eating out? Vacations? Make a list of where your money is going and take necessary steps to resist your desire. For example, if you spend too much money on dining out on weekends, stuff your cupboard with food on Friday. So you'll be more likely to stay in and cook. And you need to give up the need to keep up with others. Everyone's financial situation is different and comparison may lead to debt and dissatisfaction with what you already have.5.Why does the author mention those numbers in Paragraph 2?A.To support an idea.B.To attract readers.C.To call for actions.D.To introduce a topic.6.Which of the following may help deal with stress shopping?A.Stimulating desires.B.Recording spending.C.Turning to medicines.D.Comparing with others.7.What is the author's attitude to stress shopping?A.Unclear. B.Doubtful.C.Objective. D.Negative.8.What is a suitable title for the text?A.Does shopping benefit us?B.More stressed, women or men?C.Should we compare with others?D.Can stress shopping reduce stress?Ⅱ.读后续写[2023ꞏ武汉市高三调研]阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。

高考英语阅读理解训练及参考答案高考英语阅读理解训练1:Food serves as a form of communication in two fundamental ways.Sharing bread or other foods is a common human tradition that can promote unity and trust.Food can also have a specific meaning,and play a significant role in a family or cultures celebrations or traditions.The foods we eat —and when and how we eat them—are often unique to a particular culture or may even differ between rural (农村的) and urban areas within one country.Sharing bread,whether during a special occasion (时刻) or at the family dinner table,is a common symbol of togetherness.Many cultures also celebrate birthdays and marriages with cakes that are cut and shared among the guests.Early forms of cake were simply a kind of bread,so this tradition has its roots in the custom of sharing bread.Food also plays an important role in many New Year celebrations.In the southern United States,pieces of corn bread represent blocks of gold for prosperity (兴旺) in the New Year.In Greece,people share a special cake called vasilopita.A coin is put into the cake,which signifies (预示) success in the New Year for the person who receives it.Many cultures have ceremonies to celebrate the birth of a child,and food can play a significant role.In China,when a baby is one month old,families name and welcome their child in a celebration that includesgiving redcolored eggs to guests.In many cultures,round foods such as grapes,bread,and moon cakes are eaten at welcome celebrations to represent family unity.Nutrition is necessary for life,so it is not surprising that food is such an important part of different cultures around the world.*大意:*讲述了食物在不同文化中的作用。

一、高中英语阅读理解1.(2019•浙江)阅读理解California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor(因素).The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.Many factors contributed to the decline, said Patrick Mclntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources(资源).But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt(融雪).Since the 1930s, Mclntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.(1)What is the second paragraph mainly about?A. The seriousness of big-tree loss in California.B. The increasing variety of California big trees.C. The distribution of big trees in California forests.D. The influence of farming on big trees in California.(2)Which of the following is well-intentioned but may be bad for big trees?A. Ecological studies of forests.B. Banning woodcutting.C. Limiting housing development.D. Fire control measures.(3)What is a major cause of the water shortage according to Mclntyre?A. Inadequate snowmelt.B. A longer dry season.C. A warmer climate.D. Dampness of the air.(4)What can be a suitable title for the text?A. California's Forests: Where Have All the Big Trees Gone?B. Cutting of Big Trees to Be Prohibited in California Soon.C. Why Are the Big Trees Important to California Forests?D. Patrick Mclntyre: Grow More Big Trees in California【答案】(1)A(2)D(3)C(4)A【解析】【分析】本文属于议论文,围绕加利福尼亚的大树从20世纪30年代以来大量减少为主题,探讨出现这一现象的原因。

But that wasn't the most extraordinary thing. The most extraordinary thing was that the Lake Shore Drive Bridge is a drawbridge.“The first time, it was scary," Dorsay told a reporter from the Chicago Sun-Times, recalling how a bell would ring and his home would tip into the air, allowing ships to pass along the Chicago River below. "After that, it was almost like riding a ferry's wheel." Brian Steele, a spokesman for the Chicago Department of Transportation, puts it more straightforwardly. "Essentially," he says, "it changed his living space from horizontal(水平的) to vertical. "Dorsay had a history of homelessness and emotional problem. but inthe bridge. he thought, he had finally found a kind of stability. "You've got to be kind of agile(敏捷的)," he admitted.

一、高中英语阅读理解1.阅读理解Shark attacks not only disturb beach activities, but can affect associated tourist industries. Shark nets are a common solution to preventing shark attacks on beaches, but they cause dangers to sea ecosystems.Seeking a cost-effective way to monitor beach safety over large areas, we have developed a system called Shark Spotter. It combines artificial intelligence (AI), computing power, and drone (无人机) technology to identify and warn lifesavers to sharks near swimmers. The project is a cooperation between the University of Technology Sydney and The Ripper Group, which is pioneering the use of drones—called "Westpac Little Ripper Lifesavers"—in the search and rescue movement in Australia.SharkSpotter can detect sharks and other potential threats using real-time aerial imagery. The system analyses video from a camera attached to a drone to monitor beaches for sharks, send warnings, and conduct rescues. Developed with techniques known as "deep learning", the Shark Spotter system receives imagery from the drone camera and attempts to identify all objects in the scene. Once certain objects are detected, they are put into one of 16 categories: shark, whale, dolphin, rays, different types of boats, surfers, and swimmers.If a shark is detected, Shark Spotter provides both a visual sign on the computer screen and an audible warning to the operator. The operator confirms the warning and sends text messages from the Shark Spotter system to the Surf Life Savers for further action. In an emergency, the drone is equipped with a lifesaving flotation pod (漂浮仓) together with an electronic shark repellent (驱逐装置) that can be dropped into the water in cases where swimmers are in severe trouble, trapped in a rip, or if there are sharks close by.In January 2018, the Westpac Little Ripper Lifesavers was used to rescue two young swimmers caught in a rip at Lennox Head, NSW. The drone flew down the beach some 800 meters from the lifeguard station, and a lifesaving flotation pod was dropped from the drone.

(英语)高考英语阅读理解专项训练及答案及解析一、高中英语阅读理解1.阅读下列短文,从短文后每题所给的A、B、C和D四个选项中,选出最佳选项。

A new technology is going to ripe, one that could transform our daily lives, help to form new industries, even remove world economic powers from their present positions. Unlike the wave of industrialization that began in the West and spread later to the rest of the world, the new developments are taking place in research labs all over the globe—and Asians are in the forefront. Physicists are creating a new class of materials that display an amazing property unforeseen even two years ago—superconductivity (超导体技术).Used today only in specialized equipment, super conductors have the potential to radically change most of the electrical and electronic appliances found in the home, making them smaller, more powerful and efficient. They could free our cities of pollution by replacing petrol and diesel (柴油) vehicles with electric cars, and cut the cost of electricity. The new materials do something that even the best of conductors such as copper and silver cannot—they do away with all electrical resistance. The significances for energy storage are great.The technology is in its early stage, still accessible to countries that decide to invest brains and money. For 75 years it had remained little more than a scientific curiosity with limited practical use because the phenomenon occurred only at extremely low temperatures. It was first observed in 1911 by a Dutch scientist named Heike Kamerlingh Onnes, who cooled mercury (水银) to temperatures below -269℃ with liquid helium (氦). Then in January last year, two IBM scientists, K. Alex Muller and J. George Bednorz, found a metal oxide ceramic (氧化陶瓷) that superconducted at -243℃. Their report went largely unnoticed until last December, when it was confirmed at a scientific meeting in Boston. Today Japan, India, China and other Asian countries all have their share of experts who spend their days and nights in labs, acting as midwives (助产士) to a new technology.(1)As is indicated in the passage, the technology of superconductivity ____________. A. has already been developed B. is still under developmentC. will be used only in specialized equipmentD. will be used in daily lives in a few years(2)The new technology differs from the others in that ____________.A. it began in the East and spread later to the rest of the worldB. it began in the West and spread later to the rest of the worldC. it is being cultivated in research labs around the worldD. it is accessible to physicists who are intelligent and rich(3)From the passage, we may conclude that ____________.A. Asian scientists gain the lead in the growth of the new technologyB. Dutch scientists kept reporting new findings for the last 75 yearsC. IBM scientists' report receive immediate attention all over the worldD. the West was astonished at the new technology developed by the Asians(4)Which of the following would be the best title for the passage?A. The Prospect of a New TechnologyB. Superconductivity: A New TechnologyC. A New Technology: The Key to Change the Way of Our LivesD. A New Technology: A Joint Effort of Many Countries【答案】(1)B(2)C(3)A(4)B【解析】【分析】本文是一篇说明文,介绍了超导体技术的发展潜能和发展状况。
