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。

But researchers are warning that the blueish light their screens emit can stop users getting a good nights sleep. That is because this type of light mimics daylight, convincing the brain that it is still daytime. Blue light suppresses production of a brain chemical called melatonin, which helps us fall sleep. This is because our brains have evolved to be wakeful during daylight hours. By contrast, light which is more orange or red in tone does not reduce melatonin production, perhaps because our brains recognize it as a cue that the day is ending.Neurologists (神经病学家) have known for years that staring at screens late in the evening can disrupt sleep. Researchers at the Lighting Research Centre, at the Rensselaer Polytechnic Institute in New York, are warning that looking at tablet displays for more than two hours leads to a suppression of our natural melatonin levels as the devices emit optical radiation (光辐射) atshort wavelengths - in other words, they emit bluer light.They say: Although turning off devices at night is the ultimate solution, it is recommended that if these devices are used at night displays are dimmed as much as possible and that the time spent on them before bed should be limited.They drew their conclusions after measuring melatonin levels in 13 volunteers, after they had spent time viewing iPads at full brightness at a distance of 10 inches, for two hours. Melatonin levels were significantly lower after they had done this, than they were after the volunteers had viewed their iPads for the same time, but while wearing orange glass goggles, which cut out the blue light.They wrote in the journal Applied Ergonomics that tablet makers could tune the spectral power distribution of self-luminous devices (自发光设备的频谱功率分布) so that they disrupted the sleep patterns of users less.It is not just a good nights sleep that could be jeopardized (危害) by too much late night screen time. Researchers know that persistent disruption to sleep patterns can lead to an increased risk of obesity, and even breast cancer. However, these studies tend to be comparisons of those with chronic (慢性的) sleep disruption, such as long term shift workers, with those who have normal sleep patterns.高考英语阅读理解题目及答案12. What is it that stops users getting a good nights sleep?A. ScreensB. blueish lightC. MelatoninD. Orange or red light13. Based on their findings, researchers have made the following suggestions except that ________.A. Devices like iPads should be turned off at night.B. Tablet makers should make improvements in devices.C. Users should view iPads at full brightness instead of wearing orange glass goggles.D. The time spent on screen before bed should be controlled.14. We can infer from the passage that _________.A. Orange and red light does no good to a good nights sleep.B. Our brains recognize orange or red light in tone as a cue that the day is ending.C. The less melatonin our body produces, the easier we fall asleep.D. Too much late night screen time leads to more than sleep problem.15. The writers purpose for writing this article is to ________.A. inform readers of a recent research.B. complain about problems caused by using iPads before bed.C. offer some suggestions on late night screen viewing.D. advocate late night screen viewing.参考答案12-15 BCDA。

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。

高考英语阅读理解试题及答案精选高考英语阅读理解试题及答案1高考英语阅读理解试题及答案2 FLORENCE, ItalySvetlana Cojochru feels hurt. The Moldovan has lived here seven years as a caregiver to Italian kids and the elderly, but in order to stay shes had to prove her language skills by taking a test which requires her to write a postcard to an imaginary friend and answer a fictional job ad.Italy is the latest Western European country trying to control a growing immigrant(移民) population by demanding language skills in exchange for work permits, or in some cases, citizenship.Some immigrant advocates worry that as hard financial times make it more difficult for natives to keep jobs, such measures will become more a vehicle for intolerance than integration(融合). Others say its only natural that newcomers learn the language of their host nation, seeing it as a condition to ensure they can contribute to society.Other European countries laid down a similar requirement for immigrants, and some terms are even tougher. The governments argue that this will help foreigners better join the society and promote understanding across cultures.Italy, which has a much weaker tradition of immigration, has witnessed a sharp increase in immigration in recent years. In 1990,immigrants numbered some 1.14 million out of Italys then 56.7 million people, or about 2 percent. At the start of this year, foreigners living in Italy amounted to 4.56 million of a total population of 60.6 million, or 7.5 percent, with immigrants children accounting for an even larger percentage of births in Italy.Cojochru, the Moldovan caregiver, hoped obtaining permanent residence(居住权) would help her bring her two children to Italy; they live with her sister in Moldova, where salaries are among the lowest in Europe. She was skeptical that the language requirement would encourage integration.Italians always "see me as a foreigner,' an outsider, even though shes stayed in the country for years and can speak the local language fluently, she said.1. Why does Cojochru have to take a language test?A. To continue to stay in Italy.B. To teach her children Italian.C. To find a better job in Italy.D. To better mix with the Italians.2. Some people worry that the new language requirement may ________.A. reduce Italys population quicklyB. cause conflicts among peopleC. lead to financial difficultiesD. put pressure on schools3. What do we know about Cojochru?A. She lives with her sister now in Italy.B. She enjoys learning the Italian language.C. She speaks Italian well enough for her job.D. She wishes to go back to her home country. 答案1. A2. B3. C。
高考英语高中英语阅读理解习题及答案
一、高中英语阅读理解1．阅读理解Empathy (同理心)is one of those strange qualities—something almost everyone wants, but few know how to truly give or receive it. In a world where self-satisfaction is emphasized, it is in short supply but high demand. This is all the more reason to teach the next generation what it means to have empathy for those around them.What Is Empathy?— Many people confuse sympathy and empathy, but they are two distinct values. Empathy is not just the ability to understand someone's feelings; criminals often take advantage of people by appearing to understand their feelings and subsequently gaining their trust. Empathy is more than that. Not only is it the ability to recognize how someone feels, but it also values and respects the feelings of another person. It means treating others with kindness, dignity, and understanding.Kids Need To See Adults Show Empathy—While some children are gifted with naturally kind hearts, in most cases kids need to see empathy modeled by the adults around them. It begins with the way parents relate to their children. Parents who show an interest in the things that matter to their kids and respond to emotions in a positive and caring way are teaching the skill of empathy.Meet Emotional Needs—When children have their emotional needs met, two things happen. They learn how to meet the emotional needs of others and they are anchored in what they are receiving, meaning that they are secure enough to give to others when the need arises but first they need to receive. An empty jug cannot fill a cup.It's a good idea to talk to kids about emotions and how other people experience them. Give their emotions names (for example, jealousy, anger, and love) and teach them that these are normal. Talk to them about how to handle emotions in a positive way and point out situations where other people are experiencing emotions. Teach them about respecting the emotions of others and show them how to act in a situation where a response is required.（1）Why is it that the next generation are taught to have empathy?A. Because people tend to center themselves.B. Because everyone lacks empathy.C. Because empathy is a strange quality.D. Because it's better to give than to receive.（2）Which situation can empathy be used in?A.When a mathematician is calculating the area of a farmland.B.When a teacher is comforting a student about his failure in exams.C.When a criminal is cheating a victim.D.When a dancer is dancing to music.（3）What does the underlined sentence "An empty jug cannot fill a cup" mean?A.An empty jug is too small to hold a cup.B.It's a must to talk to kids about emotions.C.Adults should set an example to kids.D.Kids give empathy with their emotional needs met first.（4）What is the main topic of the passage?A.How to train kids to have empathy.B.How to distinguish sympathy and empathy.C.How to help kids finish empathy-related tasks.D.Whether kids can be trained to be more empathetic.【答案】（1）A（2）B（3）D（4）A【解析】【分析】本文是一篇说明文，在一个强调自我满足的世界里，我们更有理由教导下一代，对周围的人抱有同理心意味着什么。

高考英语阅读理解训练附参考答案
高考英语阅读理解训练附参考答案高考英语阅读理解训练1：Life in the ClearTransparent animals let light pass through their bodies the same way light passes through a window.These animals typically live between the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach.Most of them are extremely delicate and can be damaged by a simple touch.Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone.They never touch anything unless theyre eating it, or unless something is eating them.”And they are as clear as glass.How does an animal become seethrough? Its trickier than you might think.The objects around you are visible because they interact with light.Light typically travels in a straight line.But some materials slow and scatter(散射)light, bouncing it away from its original path.Others absorb light, stopping it dead in its tracks.Both scattering and absorption make an object look different from other objects around it, so you can see it easily.But a transparent object doesnt absorb or scatter light, at least not very much. Light can pass through it without bending or stopping.Thatmeans a transparent object doesnt look very different from the surrounding air or water.You dont see it—you see the things behind it.To become transparent, an animal needs to keep its body from absorbing or scattering light.Living materials can stop light because they contain pigments(色素) that absorb specific colors of light.But a transparent animal doesnt have pigments, so its tissues wont absorb light.According to Johnsen, avoiding absorption is actually easy.The real challenge is preventing light from scattering.Animals are built of many different materials—skin, fat, and more —and light moves through each at a different speed.Every time light moves into a material with a new speed, it bends and scatters.Transparent animals use different tricks to fight scattering.Some animals are simply very small or extremely flat.Without much tissue to scatter light, it is easier to be seethrough.Others build a large, clear mass of nonliving jellylike(果冻状的)material and spread themselves over it.Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does.They need to look uniform.But how theyre doing it is still unknown.One thing is clear：for these larger animals, staying transparent is an active process.When they die, they turn a nontransparent milky white.*大意：你见过透明生物吗?*介绍了透明的海洋生物。
