2021高考英语二轮专题阅读理解训练精品题（7）阅读明白得-----AThe week I turned 50, my marriage came to a sudden end. My house, furniture and everything I’d owned was sold to pay debts that I didn't’ even know I had. In a week I had lost my husband, my home and my parents who had refused to accept a divorce in the family. I’d lost everything except my four teenage children. I used every penny I had to buy five plane tickets from Missouri to Hawaii. Everyone said I was crazy to think I could just go to an island and survive. I was afraid they were right.Knowing that no one in the world was going to help us, I rented a cheap apartment.I worked 18 hours a day and lost 30 pounds because I lived on one meal a day. One night as I walked alone on the beach, I saw the red orange glow of the lave (火山岩) pouring out of Kilarea Volcano in the distance. It was time to live my imagination!The next day I quit my job and invested my last paycheck in art supplies and began doing what I loved. I hadn’t painted a picture in 15 years. I wondered if I could still paint. My hands trembled the first time I picked up a brush. But before an hour had passed, I was lost in the colors spreading across the canvas in front of me. And as soon as I started believing in myself, other people started believing in me, too. The first painting sold for $1,500 before I even had time to frame it.The past six years have been filled with adventures. My children and I have gone swimming with dolphins, watched whales and hiked around the volcano. We wake up every morning with the ocean in front of us and the volcano behind us. The dream I had more than 40 years ago is now reality. I’m living freely and happily ever after.1. It can be inferred from the passage that ______.A. the writer didn’t expect her marriage would endB. the writer’s parents were content with her divorceC. the writer’s husband took away most of her propertyD. there was something wrong with the writer’s job答案解析：答案为A。

One morning more than thirty years ago, I entered the Track Kitchen, a restaurant where everyone from the humblest(卑微的) to the most powerful came for breakfast. I noticed an empty chair next to an elderly, unshaven man, who looked somewhat disheveled. He was wearing a worn-out hat and was alone. I asked if I might join him. He agreed quietly and I sat down to have my breakfast. We cautiously began a conversation and spoke about a wide rang of things. We never introduced ourselves. I was concerned that he might have no money and not be able to afford something to eat. So as I rose to go back to the counter and buy a second cup of coffee, I asked, "My I get you something?" "A coffee would be nice." Then I bought him a cup of coffee. We talked more, and he accepted another cup of coffee, Finally, I rose to leave, wished him well, and headed for the exit. At the door I met one of my friends. He asked, "How did you get to know Mr. Gal breath?" "Who?" "The man you were sitting with. He is chairman of the Board of Churchill Downs." I could hardly believe it. I was buying, offering a free breakfast, and feeling pity for one of the world's richest and most powerful men! My few minutes with Mr. Gal breath changed my life.

2021年高考英语二轮复习阅读理解精练精析21 (I)

2021年高考英语二轮复习阅读理解精练精析21 (I) Having a great teacher can be life-changing. Mr. Goodney, my 9th grade Advanced English teacher, pushed me in ways I hadn’t been pushed in the classroom previously. He didn’t grade me pared to my classmates；he graded us on a personal grading scale.Mr. Goodney encouraged me but I just couldn’t seem to please Mr. Goodney, no matter how hard I worked. I continued to see the dreaded Bs, sometimes even a C, so frequently that I said goodbye to my hopes of being a middle student. I was a really diligent nerd(令人厌烦的人).Yet at the end of the semester when report cards came out, I had an “A” next to my English class, and I realized that the letter he had written on my report card was just a way to make me work harder than I ever had. He made me push myself to think deeper, write better, and analyze more thoroughly. He didn’t hate me as I initially thought, and I looked back embarrassed about all those times when I showed frustration and dissatisfaction with a returned grade.He would write a positive ment on one of my papers that would invigorate me to work even harder even if I made a little bit progress. These sporadic (零星的) good words would motivate me to do whatever it took to earn thosepraising ments on my next paper and push me to try and top my last assignment. After we all improved he expected perfection and those high standards made all of us better writers, creators, good students, and useful people.Mr. Goodney inspired me to bee an English teacher although I felt like I fell below his standards in a classroom. Now I have bee a high school teacher. Thinking of him from time to time makes me try to e up with fresh and creative teaching ways just as he did.From my experience I believe a good teacher is very important. Mr. Goodney inspires me to this day, and I wish I could travel back to the 9th grade for just one day in the old classroom, so I can fully thank him, which I didn’t do at that time.1. According to the passage, Mr. Goodney graded the author _______ .A. in order to encourage himB. according to his real marksC. pared to his classmatesD. as most teachers usually do2. What do we know about the author from the passage？A. He only did well in English and often got praises.B. He didn’t study his lessons hard enough.C. He got good marks on one of his report cards.D. He had confidence in being a top student.3. The underlined words “invigorate me” in Paragraph 4 can be replaced by _______ .A. take pity on meB. encourage meC. play tricks on meD. offer me help4. What does the author believe according to his own experience?A. He would have been more successful if he had worked harder.B. Nothing is difficult for a student if he meets a good teacher.C. His English teacher had set too high standards for him.D. A good teacher had a lifelong influence on him.(B)We once had a poster petition in our fifth grade art class.“You could win prizes, ” our teacher told us as she wrote the poster information on the blackboard. She passed out sheets of construction paper while continuing, “The first prize is ten dollars. You just have to makesure that the words on the blackboard appear somewhere on your poster. ”We studied the board critically. Some of us looked with one eye and held up certain colors against the blackboard, rocking the sheets to the right or left while we conjured up our designs. Others twisted their hair around their fingers or chewed their erasers while deep in thought. We had plans for that ten-dollar grand prize, each and every one of us. I’m going to spend mine on candies, one hopeful would announce, while another practiced looking serious, wise and rich.Everyone in the class made a poster. Some of us used parts of those fancy paper napkins(餐巾纸), while others used nothing but colored construction paper. Some of us used big designs, and some of us preferred to gather our art tidily down in one corner of our poster and let the space draw the viewer’s attention to it. Some of us would wander past the good students’ desks and then return to our own projects with a growing sense of hopelessness. It was yet another grown-up trick of the sort they seemed especially fond of, making all of us believe we had a fair chance, and then always—always —rewarding the same old winners.I believe I drew a sailboat, but I can’t say that with any certainty.I made it. I admired it. I determined it to be the very best of all of the posters I had seen, and then I turned it in.Minutes passed.No one came along to give me the grand prize, and then someone distracted me, and I probably never would have thought about that poster again.I was still sitting at my desk, thinking, What poster? when the teacher gave me an envelope with a ten-dollar bill in it and everyone in the class applauded for me.5. What was the teacher’s requirement for the poster?A. It must appear in time.B. It must be done in class.C. It must be done on a construction sheet.D. It must include the words on the blackboard.6. The underlined phrase in paragraph 3 most probably means _______ .A. formed an idea forB. made an outline forC. made some space forD. chose some colors for7. After seeing the good students’ designs, some students _______ .A. loved their own designs moreB. thought they had a fair chanceC. put their own designs in a cornerD. thought they would not win the prize8. We can infer from the passage that the author _______ .A. enjoyed grown-up tricks very muchB. loved poster petitions very muchC. felt surprised to win the petitionD. became wise and rich after the petition答案解析【文章大意】一个好的老师可以改变一个人的命运。

2021年高考英语二轮复习专题07阅读理解Ⅳ：篇章结构题讲含解析【考纲解读】【剖析全国高考真题】——预测高考命题方向[xx·全国卷Ⅰ，D]Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years canstill swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember the story of Cinderella or Goldilocks and the Three Bears.One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials(尝试) increase the length of time we will remember it.In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.The multiplication tables(乘法口诀表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.The law of overlearning explains why cramming(突击学习)for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.68.The author explains the law of over learning by_________.A. presenting research findingsB. setting down general rulesC. making a parisonD. using examples【答案】68. D【解析】【高考预测】纵观近几年全国高考试题，很少出现此类题型，但这一题型在地方高考和模拟试题中时有出现，因此不排除xx年全国高考试题可能会①设置1道篇章结构题，考查考生对整个篇章或其中的某个段落结构和脉络的把握。

专题限时集训(二十一) 阅读理解训练7 篇章结构题A(2016·广东省五校协作体联考)There are many places to go on safari in Africa，but riding a horse through the flooded waters of Botswana's Okavango Delta must rank as one of the world's most exciting wildlife journeys.Several safari camps operate as the base for this adventure，providing unique rides twice a day to explore deep into the delta.The camps have excellent horses，professional guides and lots of support workers.They have a reputation for providing a great riding experience.The morning ride，when the guides take you to beautiful，shallow lakes full of water lilies，tends to be more active.It is unlike any other riding experience with rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face.It is truly exciting.You are very likely to come across large wild animals，too.On horseback it is possible to get quite close to elephants，giraffes and many other animals.The sense of excitement and tension levels rise suddenly though，and so does your heart rate，as you move closer to them.In the evening，rides are usually at a more relaxed and unhurried pace，with golden light streaming across the grassy delta and the animals coming out to eat and drink.Sedate though they are, rides at this time of day are still very impressive.As the sun's rays pass through the dust kicked up by the horses，the romance of Africa comes to life.Back at the camp you can kick off your boots and enjoy excellent food and wine.Looking back on your day，you will find it hard to deny that a horseback safari is as close as you will ever come to answering the call of the wild.本文主要介绍了非洲的游猎。

高考英语二轮复习专题阅读理解精选1So long as teachers fail to distinguish between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them・ It is certainly not endless hours spent in activities about reading. Douglas insists that "reading cannot be taught directly and schools should stop trying to do the impossible^.Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity. It can be seen and observed.Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.If teacher and learner roles are not interchangeable ,what then can be done through teaching that will aid the child in the quest （探索）for knowledge? Smith has one principal rule for all teaching instructions. "Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children."When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading.26.The problem with the reading course as mentioned in the first paragraph is that.A.it is one of the most difficult school coursesB.students spend endless hours in readingC.reading tasks are assigned with little guidanceD.too much time is spent in teaching about reading27.The teaching of reading will be successful if _______________ ・A.teachers can improve conditions at school for the studentsB.teachers can enable students to develop their own way of readingC.teachers can devise the most efficient system for readingD.teachers can make their teaching activities observable28.The underlined word “scrutiny” most probably means"_____________A.inquiryB. observationC. controlD. suspicion29.According to the passage, learning to read will no longer be a difficult task when ______________•A.children become highly motivatedB.teacher and learner roles are interchangeableC.teaching helps children in the search for knowledgeD.reading enriches children's experience30.The main idea of the passage is that ______________ .A.teachers should do as little as possible in helping students learn to readB.teachers should encourage students to read as widely as possibleC.reading ability is something acquired rather than taughtD.reading is more complicated that generally believed【答案与解析】26—30 DBBAC木文是一篇议论文，在对传统的阅读教学方式进行批判的同时，论述了作者自己阅读的教学观：阅读的教与学是两个完全不同的过程。

2021届高考英语二轮阅读理解专项练习(二十一)

2021高考英语二轮阅读理解专项练习（二十一）（A）Most people aren’t good at creative problem solving for two reasons: (1) They are not trained in how to be creative. (2) They don’t understand group strength well enough to harness （驾驭）their power to maximize group creativity.A key element of creativity is applying existing knowledge to a new problem. The more people getting involved in solving it, the more knowledge there is to work on it. Unfortunately, research shows that the traditional brainstorming methods fail to achieve that goal. When groups get together to exchange ideas, they actually come up with fewer ideas overall than if they each had worked alone.To fix this problem, you should consider the two stages of group problem-solving: divergence（分散）and convergence（集中）. Divergence happens when the group considers as many different potential solutions as possible. Convergence happens when the various proposed solutions are evaluated and reduced to a smaller set of candidate solutions to the current problem.The essential principle of group creativity is that individuals working alone diverge, whereas group members working together converge. In groups, once a member states a potential solution, that makes others think about the problem similarly. That is why groups working together diverge less than individuals working alone.Therefore, be aware of when to diverge and when to converge. For example, early in the problem-solving process, have group members work alone to write down statements describing the problem. Then get them back to discuss their descriptions. The group discussion will lead everyone to accept one or a small number of these statements to work on—this is healthy convergence.When starting to generate solutions, you again want divergence. Have people work alone to start. Then collect people’s initial ideas and send them around to others and allow the divergence to continue as everyone individually builds on the ideas of other members.Finally, let the group discuss the resulting ideas. This discussion will gradually lead the group to converge on a small number of candidate solutions.This simple method works effectively, because it respects what individuals and groups do best.1 .Research shows that the traditional brainstorming methods ______.A.actually limit group creativityB.greatly encourage group creativityC.enable people to form more ideas togetherD.prevent people’s involvement in the problems2 .According to Para. 4, when a member presents an idea, others tend to_____.A.think the other way roundB.follow his way of thinkingC.be more confident in their own ideasD.be less willing to share their own ideas3 .What should group members first do early in the problem-solving process?A.Discuss the problem.B.Simplify the problem.C.Put down group statements together.D.Write down their individual descriptions.4 .How can each group member make changes to his initial solution?A.By adding in collected evidence.B.By reorganizing his own words.C.By drawing on others’ ideas.D.By making his statement briefer.5 .What is the author’s purpose in writing the passage?A.To advocate a way to make group thinking more effective.B.To demonstrate the difficulty in organizing group thinking.C.To highlight the differences between divergence and convergence.D.To show the advantage of group thinking over individual thinking.（B）If you thought pilots dimmed(调暗) the lights before takeoff to give you some shuteye,think again.Believe it or not,the dim lighting could actually help save your life in case of a plane emergency.The dimmed lights before taking off from the runway and landing are a flight precaution used to help passengers’eyes adjust more quickly during an emergency escape.“Going from abrightly-lit environment to one that’s completely dark would require some time for our eyes to focus and see the escape slide,”Alice Theriault,service director for Air Canada wrote in a press statement.“Since we need to have all the seconds on our side in the event of an emergency,dimming the lights is one of many steps we take to ensure the safety of our customers.”The phenomenon that your eyes see those strange speckles (小斑点) as your sight adjusts to a dark place after being in a light place is called dark adaptation.It normally takes our eyes about 20 to 30 minutes to see best in a dark room.The brighter the lights,the longer it takes for our eyes to adjust,which is why dimming the plane lights could shorten your “dark adaptation” time since you haven’t been sitting under fluorescent bulbs (荧光灯) all flight.Not only does dimming lights add valuable time to the escape process,it also reduces the tension on your eyes if you need to look outside,or see the emergency lighting along the passage.“It helps keep you in the right direction,”Patrick Smith,an airline pilot and author of Cockpit Confidential told The Telegraph.“It also makes it easier for flight attendants to assess any outside risks,such as fire or debris,that might affect an escape.”So next time a pilot dims the lights,just know it’s for your safety,even though it creates a gentle atmosphere for your takeoff into the sky.1.The lights are dimmed before takeoff to help passengers .A.take a short breakB.escape in time of emergencyC.create a warm atmosphereD.adapt their eyes to the bright environment2.What is one of the roles of shortening “dark adaptation” time?A.Slowing down the landing.B.Adjusting the plane lights.C.Keeping passengers calm.D.Helping the crew judge outside risks.3.What does the underlined word “It” in the last paragraph refer to?A.Dimming lights.B.The escape process.C.Reducing tension.D.The passage.4.What is the text mainly about?A.A tip of air travel.B.An emergency event on a plane.C.A warning message on a plane.D.An explanation of an airline safety measure.（C）If you were bringing friends home to visit, you could show them the way. You know the landmarks—a big red house or a bus-stop sign. But what if you were swimming in the middle of the Atlantic Ocean? Could you still find your way home? A loggerhead turtle（海龟）could.According to Dr. Ken Lohmann, loggerheads have a magnetic（磁力的）sense based on Earth’s magnetic field. It helps them locate the best spots for finding food and their home beaches.Scientists already know that several other animals, such as whales and honeybees, can detect （探测到）magnetic fields. The difference between them and loggerheads, however, is the way they learn to use their magnetic sense. Young whales and honeybees can learn from adults. Loggerheads are abandoned as eggs.As newborn loggerheads have no adults to learn from, what helps them figure out how to use their magnetic sense? Lohmann thinks one of the cues was light on the sea.Baby loggerheads hatch only at night. However, a small amount of light reflects off the ocean. The light makes that region brighter. Heading toward the light helps them get quickly out to sea, where they can find food. Lohmann tested whether newborn loggerheads use this light source to set their magnetic “compasses”（罗盘）. He and his team put some newborns in a water tank and recorded which way they swam. Around the tank, the scientists created a magnetic field that matched the Earth’s. They set a weak light to the east of the magnetic field. Then they let the newborns go.At first, the newborns swam toward the light. After the scientists turned off the light, the turtles that had seen the light in the east always swam toward east. When the researchers reversed （颠倒）the magnetic field, these turtles turned around and swam toward the new “east”.This and the follow-up experiments all showed that loggerheads use light from the outsideworld to set their magnetic “compasses” and then remember the “correct” direction. If a turtle hatches on a brightly-lit beach, that would damage its magnetic sense forever and make survival hard for the turtle.Lohma nn’s work has led others to protect the habitat of this endangered species. Yet many questions about these creatures remain unanswered, and researchers have a lot to study.1..Loggerheads and whales differ in the way they______.A.bring up their youngB.recognize landmarksC.detect magnetic fieldsD.learn to find directions2. What is needed for newborn loggerheads to set their magnetic sense?A.Weak light reflected off the ocean.B.Help from adult loggerheads.C.Bright sunlight from the sky.D.Food in warmer waters.3 .In the experiment, after the newborns’ magnetic sense was set, their moving direction was determined by ____.A.the lightB.the magnetic fieldC.other unknown factorsD.the light and the magnetic field4. What is the significance of Lohmann’s research work?A.It enables researchers to keep track of turtles.B.It contributes to the studies of the magnetic field.C.It offers a new solution to environmental pollution.D.It helps protect the loggerheads’ living environment.5.What could be the best title of the passage?A.Experiments on LoggerheadsB.The Survival of the Sea TurtleC.The Loggerhead’s Built-in “Compass”parison of Loggerheads and Other Animals（D）Growing up in one of the poorest communities with most crimes in Los Angeles,US,being raised by a poorly-educated single mother and attending the worst-quality public school,not many people expected much of me,so I chose to expect something of myself.On my 12th birthday,I bought a poster of Harvard University to hang in my room.Being at Harvard became my dream—I saw myself attending class in Sanders Theater,studying in Widener Library and eating in Annenberg Hall.Driven by this dream,I kept studying hard.I’d begin my day by asking myself these two questions—What do I want in my life?Are the things I am doing today going to get me closer to that life?Asking myself the questions gave me the courage to ask over 50 Harvard students for advice on my application essays,it gave me the energy to study just one more hour on my SATs when others were asleep,and it gave me the determination to apply for just one more scholarship when already refused many times.Moreover,reminding myself of my goal each day made it easy to say no to the same choices my friends made,because they would never get me closer to my goal.I found that even being poor could not take away my power to decide what I chose to do with my life.Every day I could feel myself getting closer and closer to my goal as my writing got better,my SAT score increased,and my scholarship offers started coming in.On March 31st,2011,an email arrived from Harvard.The first word was“Congratulations!”.Tears of joy filled my eyes.Who you are today is the result of the decisions you made yesterday,and who you will be tomorrow will be the result of the choices you make today.Who do you want to be tomorrow?1.What does the first paragraph mainly tell us?A.It describes the author’s early living conditions.B.It proves that the author once lived an unhappy life.C.It shows how many people treated the author badly.D.It shares the author’s dream with readers.2.What is the author’s attitude to the hardship?A.Disappointed.B.Positive.C.Thankful.D.Sorrowful.3.What did the author want to tell us most?A.A famous university,a successful life.B.The earlier you set yourself a goal,the better.C.What doesn’t kill you makes you stronger.D.Your choices determine who you are.（E）Over a hundred years ago in 1911,something strange was found in the glaciers of Antarctica.Crilffith Taylor—an Australian geologist,had discovered a blood red stream pouring out of the ice cascades (瀑布) of Talor Glacier!Popularly known as the Blood Falls,scientists had not been able to find the reason behind the blood red liquid flowing through the ice—until recently.The mystery of the Blood Falls had finally been solved.When these falls were first discovered,scientists had believed that the red colour came from a large amount of red algae (海藻) concentrated in the water.Red algae contain a pigment (色素) which reflects red light,making the algae appear red.This theory made sense,until it was later found that algae do not play a part in the red color of the flowing liquid at all.What really causes Talor Glacier’s waters appear blood red,is the presence of iron oxide in the liquid.The waters of the Blood Falls are rich in salt and iron content,and when this water comes in contact with the air,it turns red—just like rust!The water in these falls is often referred to as “brine” by scientists because of the high salt content in the water.This reasoning behind the red colors of the falls was found back in 2003.However,the entire mystery had not yet been solved.How is it then,that the Blood Falls are not frozen?Researchers at the University of Colorado and University of Alaska found that inside the glacier,there is a network of channels and reservoirs that move the water around.Salt water has a lower freezing temperature.In addition,when any substance undergoes a change in state,it gives off heat.Therefore,the brine actually warm itself up while it’s freezing!How this works,is that when the brine is flowing through the Talor Glacier,some of it does freeze.As a result of changing state from liquid to ice,the brine gives off heat.This heat is enough to keep the rest of the brine in liquidform,which is why it flows out of the glacier.Incredible new chemistry facts found,and mystery solved!1.According to the text,the red algae theory was once considered .A.ridiculousB.reasonableC.impracticalplex2.Why do the Blood Falls look red in colour?A.Because there is too much salt and iron in the water.B.Because the liquid is rich in red algae.C.Because the flowing liquid reflects red sunlightD.Because the air is thin and rare in Antarctica.3.What is the main reason for the Blood Falls’ not freezing?A.The water continued flowing constantly.B.There is too much salt in the water.C.The brine gives off heat while freezingD.Temperatures aren’t high enough for flowing water.4.What is the passage mainly about?A.The discovery of the blood glacier.B.The birth of the Talor Glacier.C.The flowing red water in Antarctica.D.The mystery of the Blood Falls.参考答案：A篇：ABDCAB篇：BDADC篇：DABDCD篇：ABDE篇：BACD。

语鹅市安置阳光实验学校专题阅读理解经典精讲(上) 课后练习题一：Sometimes，the simplest ideas are the best. For example，to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads?Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.The heat collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 meters lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warming the groundwater, before returning to the surface through another pipe. The aquifer is thus used as a heat store.In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.1. Which of the following is true according to the first two paragraphs?A. Arian de Bondt got his idea from his boss.B. Large, flat, black surfaces need to be built in cities.C. The Dutch eng ineer’s system has been widely used.D. Heat can also be collected from asphalt roads.2. For what purpose are the diving pipes used?A. To absorb heat from the sun.B. To store heat for future use.C. To turn solar energy into heat energy.D. To carry heat down below the surface.3. From the last paragraph we can learn that________.A. some pipes have to be rearranged in winterB. the system can do more than warming up the buildingC. the exchangers will pick up heat from the street surfaceD. less heat may be collected in winter than in summer4. What is most likely to be discussed in the paragraph that follows?A. What we shall do if the system goes wrong.B. What we shall do if there are no asphalt roads.C. How the system cools the building in summer.D. How the system collects heat in spring and autumn.题二：Have you ever noticed the color of the water in a river or stream after a heavy rainfall? What do you think caused this change in color? It is soil that has been washed into the river from the riverbank or from the nearby fields.Components of SoilSoil is made up of a number of layers (层) , each having its own distinctive color and texture. The upper layer is known as the litter. It acts like a blanket，limiting temperature changes and reducing water loss. The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus (腐殖质), which is black and gives the topsoil its dark color. This layer is usually rich in nutrients, oxygen, and water. Below the topsoil is the subsoil, a layer that contains more stones mixed with only small amounts of organic matter. This layer is lighter in color because of the lack of humus. Beneath the soil lies a layer of bedrock.Soil forms from the bottom up. Over time bedrock is attacked by rain, wind, frost, and snow. It is gradually broken down into smaller particles in a process called weathering. Plants begin to grow，and rotten materials enrich the topsoil. Most of the soil in Eastern Canada ，for example ，was formed from weathered rock that was exposed when the ice disappeared 12,000 years ago.Water Beneath the SoilSurface water collects and flows above the ground in lakes ，ponds, and rivers. Once in the soil or rock, it is called groundwater. Gravity pulls groundwater through the soil in a process called percolation(渗透). Eventually the water reaches a layer called the water table. Under this is bedrock through which water cannot percolate.As water percolates downward, it dissolves organic matter and minerals from the soil and carries them to deeper layers. This causes a serious problem because plants require these nutrients for growth. Soil pHSoil can be acidic, neutral, or basic. The pH of the soil is determined by the nature of the rock from which it was formed，and by the nature of the plants that grow and rot in it.The acidity of rain and snow can lower the pH of the groundwater that enters the soil. By burning fossil fuels such as coal ，oil and gasoline，humans have been contributing to higher levels of acidity in many soils. When fossil fuels are burned，gases are released into the air and then fall back to earth as acid rain. Acid soil increases the problem of carrying nutrients to lower soil levels. As nutrients are removed，soilis less fertile. Plants grow more slowly in acidic soil，and also become easily attacked by diseases.1. The layer of soil that provides necessary nutrients for plant growth is called________.A. litterB. TopsoilC. humusD. subsoil2. According to the text, which of the following is NOT true?A. Soil forms from weathered rock on the earth surface.B. The deeper layer of soil is darker in color than the surface soil.C. Air pollution is partially responsible for acid soil.D. Groundwater tends to carry away nutrients for plant growth.3. We can infer from the passage that the water table lies________.A. between the topsoil layer and the subsoil layerB. in the subsoil layer above bedrockC. between the subsoil layer and bedrockD. in the bedrock layer beneath the subsoil4. The underlined word “dissolve” is used to express the idea that organic matter and minerals from soil are________.A. rushed away into the riverB. cleaned and purified by waterC. destroyed and carried away by waterD. mixed with water and become part of it 专题阅读理解经典精讲(上)课后练习参考答案题一：语篇解读：文章介绍了怎样依靠外面的柏油马路表面在冬天给楼房供暖，在夏天给楼房降温。

语鹅市安置阳光实验学校四川省成都市2016高考英语阅读理解二轮基础训练80集连载（59）【2015高考复习】阅读理解Many of us still tend to think that emotions can affect reasonablethought，and sometimes land us in trouble.But in recent years psychologists have taken quite a different view.Keith Oatley，Professor of Psychology at Glasgow University，is involved in the research which shows the fundamental importance of emotions.He believes we_are_very_ambivalent_about_them：we think of our emotions as being unreasonable，but we also consider them as essential to being human.For example，Mr Spock，a character in the television series Star Trek，is superintelligent and he has no emotions at all.However，he is never made captain of the spaceship.Maybe，this is because Mr Spock is not the kind of person you can share your feelings with—a person who shows his emotions.As Professor Oatley points out，our emotions have very important functions，for example，fear.If we cross the road and a car approaches，we usually stop moving or step back.We stop what we are doing，check what we have done and pay very careful attention to the environment.The emotion of fear makes us take this small series of actions which，on average，help preserve our safety.On the other hand，if things are going well and small problems come up，we find we can solve them with the resources we have to hand.As a consequence，we tend to feel happy and usually continue doing the job. Anger is an emotion that tends to occur when someone is preventing us from doing something.Then this small “kit” of reactions enables us to prepare ourselves to be quite aggressive to that person，or to try harder，and so on.Professor Oatley believes emotions generally occur at these important moments in actions.With fear and anger our emotions make us decide to start doing something else，while with happiness they “suggest” we continue what we are already doing.【语篇解读】相关研究表明，情感对人而言至关重要，不可或缺。

According to an essay published by the US National Oceanic and Atmospheric Administration, changes to the climate in the regions that produce cacao - the plant from which chocolate is produced - may mean that it will soon become extinct.Most of the world's cacao grows in countries close to the equator，with over half of it growing in the African nations of Ghana and Ivory Coast.It's predicted that by 2050, climate change will have accelerated the rate at which temperatures in these countries rise, making it extremely difficult for cacao to grow there.The problem doesn't lie in increased heat, however，but in lower humidity (湿度)，as it's believed that rainfall will stay at the same level if the temperature rises.“In other words, as higher temperatures squeeze more water out of soil and plants, it's unlikely that rainfall will increase enough to offset the moisture (含水量) loss,” Michon Scott, the ess ay's author, wrote.To help fight this problem, researchers from Berkeley University in the US are working on changing the DNA of cacao plants to allow them to survive in dryer conditions by using gene editing technology, according to US News.In the meantime, US company Mars, one of the world's biggest manufacturers of chocolate products, announced in January that it would spend $1 billion to help reduce the effects of climate change.“This is a world issue, and it requires everyone to work together,” Mars spokesperson Barry Parkin told Business Insider.The message here is that if we all do our part, we may be able to prevent some of the worst impacts of climate change. Or if we're unlucky, chocolate will become a thing of the past.（1）What could make it hard for cacao to survive around the equator in the future?A. The increased heat there.B. The higher humidity there.C. The decrease in rainfall there.D. The moisture loss in the soil there.（2）What does the underlined word “offset” in the seventh paragraph mean?A. hold backB. make up forC. protectD. accept（3）What will US company Mars do to help cacao survive?A. It will work hard to plant cacao in greenhouses.B. It will apply gene editing technology in planting cacao.C. It will give financial support to help fight climate change.D. It will develop cacao that can survive in dryer conditions.（4）What may be the best title of this text?A. Chocolate could become historyB. Work together to fight climate changeC. How do we grow cacao in the future?D. How do cacao plants affect climate change?【答案】（1）D（2）B（3）C（4）A【解析】【分析】本文是一篇说明文，未来由于气候的变化，用于制造巧克力的可可树可能会灭绝，所以巧克力有可能会成为历史。

人教版新高考英语二轮复习习题训练--阅读理解主旨大意题——标题归纳类(含答案)

考点分类练(八)主旨大意题——标题归纳类A(2021·山东济宁一模)During a decline in tourism, one national park in Thailand has seen a dramatic rise in “visitors”recently. So many are the hermit crabs(寄居蟹) flooding into the otherwise empty beaches of Koh Lanta that shells for them to live in have become in short supply.The Thai government moved quickly to ease the housing shortage, launching a public appeal for empty shells that netted over 200 kg. On December 5 these were distributed around the park in a ceremony.Hermit crabs rely on shells to protect their soft bodies, moving to larger shells as they grow. On Koh Lanta and the surrounding smaller islands, their rapid increase seems to be a natural phenomenon, rather than directly related to the absence of tourists. But the shortage of shells may be man-made: pretty ones have long been gathered to be sold as goods. Crabs begun to make do with potential deathtraps such as plastic caps and bottles.The shell drive is part of a government initiative to regain the balance of nature.“I have instructed all national parks to do whatever it takes,” says the minister for natural resources. His inspiration comes from the pause in tourism brought on by the epidemic. A ban on international visitors and the closure of national parks have helped nature recover, bringing endangered leatherback turtles back onto Thai beaches. In the coastal provinces of Phang Nga and Phuket, turtles have laid the largest number of eggs for 20 years.The government has decided to try to copy the policy during the epidemic in future. From now on, all national parks will be required to close for a short period during the off-season and to limit the number of tourists through a reservation system when they are open. Although such restrictions mean reduced earnings from tourism in the short term, in the longer run more parks may help to keep the tourists coming.1.What happened to the beaches of Koh Lanta recently?A.They got flooded by seawater.B.They became completely empty.C.They were packed with hermit crabs.D.They saw a constant stream of tourists.2.What contributed to the housing shortage for hermit crabs?A.Natural disasters.B.Human activities.C.Their preference for bottles.D.The government’s involvement.3.Why are turtles mentioned in paragraph 4?A.To warn turtles are dying out.B.To prove beaches are their ideal habitats.C.To stress the ecological diversity of Thailand.D.To illustrate the birth of the minister’s inspiration.4.Which of the following can be the best title for the text?A.Developing Economy or Protecting Animals?B.Closing National Parks or Drawing More Visitors?ernments Are Responsible for the Balance of NatureD.Authorities Help to Find Shelters for Homeless Hermit CrabsB(2021·山东烟台一模)Many teachers believe frequent quizzes(小测验) help students better grasp classroom material. Crede, an associate professor of psychology, was skeptical that something as simple as a quiz could positively affect students’ academic performance. He decided to dig deeper and conduct an analytic study of existing research to see if there was any proof of the idea. What he discovered truly surprised him.Crede analysed data from previously published studies that examined 52 classes with almost 8,000 students, to determine if frequent quizzes improved the students’ academic performance. Laboratory settings were kept out of the study because Crede wanted to observe whether similar studies from labs would apply to general classrooms.Crede discovered that when students were quizzed over classroom material at least once a week, they tended to perform better on midterm and final exams compared to students who did not take quizzes. He also found that students who took frequent quizzes were less likely to fail the class, especially if they were struggling with the course content. Students who struggled the most in a class seemed to benefit the greatest from frequent quizzes. The other surprising thing was how much quizzes helped reduce failure rates in classes. The chances of passing a class went through the roof where instructors used this. In addition to quiz frequency, another factor that seemed to positively affect students’ performance was immediate feedback from instructors. Also, quizzes that required students to answer with written responses proved more beneficial to their understanding of classroom material compared to multiple-choice questions.Asking teachers to grade written quizzes daily or weekly may discourage some from carrying them out in their classes. Instead, it is recommended that instructors give online quizzes that can be automatically graded by a course management system. Quiz attributes(属性) proved insignificant in the study, including whether the tests were pop quizzes or planned, or if they were online or on paper.5.What did Crede do to ensure his study’s accuracy?A.He focused on what happened in classrooms.B.He researched as many students as he could.C.He made laboratory settings as real as possible.D.He gave easy quizzes to make every student do well.6.What did Crede discover in his study?A.Frequent quizzes could remove students’ failure in classes.B.Instructors’ feedback was more important than frequent quizzes.C.Frequent quizzes were especially useful to the struggling students.D.Multiple-choice questions shouldn’t be included in frequent quizzes.7.What may be a disadvantage of frequent quizzes for teachers?A.Accessing the Internet less frequently.B.Having too many exam papers to mark.C.Being unable to get appropriate test material.D.Finding it hard to choose the right type.8.Which of the following can be the best title for the text?A.Quizzes Stimulate a Passion for CreationB.Quizzes Improve Academic PerformanceC.Quizzes Create a Heavy BurdenD.Quizzes Increase BoredomC(2021·安徽安庆高三二模)Becoming a parent brings out the best in many animals. Although parenting is usually left to the females, the males from many species will also care for the offspring. Take anemone fish(海葵鱼) for example.Despite their smaller size, the males help the females defend the nest, but only the males take care of it. They use their fins as fans to provide a constant flow of oxygen and keep the surroundings clean. They also put a lot of effort into the nest.The eggs take about five days to hatch. During this important period, the males fan them to provide oxygen and remove the rubbish. They also pick up the eggs in their mouths and move them around to remove any bacteria. One of the biggest threats comes from female sticklebacks(刺鱼), who form organised groups and attack the nests to eat all the eggs.The males defend the newborn fish and bring back the ones who move too far from the nest. Once the fish grow up, they become a little bit more independent and start to swim away. The dad swims after them, picks them up in his mouth, and spits them back into his nest. Eventually, he gets to the point where he can’t keep track of them and that’s when they separate.Doting(宠爱的) fathers are not restricted to the world of fish. In some poison frog species, the dads also warn the mums when the young ones are hungry and need to be fed.9.What does the underlined word “offspring” in paragraph 1 probably mean?A.Children.B.Relatives.C.Friends.D.Colleagues.10.What can we infer about the male anemone fish?A.They take full responsibility for building the nest.B.They are much larger than the female anemone fish.C.They are actually extremely excellent fathers.D.They frequently make attacks on other animals.11.What does it mean when the dad can’t track its young fish?A.The dad can’t tend to the young fish.B.The young fish are already independent.C.The living environment is worse.D.The dad is in a state of aging.12.What can be the best title for the text?A.The Model Father in the Animal KingdomB.The New Role of the Male Anemone FishC.The Really Caring Caregivers in LifeD.A Strange Phenomenon in Nature考点分类练(八)主旨大意题——标题归纳类【语篇导读】本文是一篇新闻报道。

AImagine living in a city made of glass. No, this isn’t a fairy tale. If you could grab your diving gear and swim down 650 feet into the Pacific Ocean off the coast of Washington State, you would witness the secret world of glass reefs.The reef you’d be looking at is made up of glass sponges(海绵). But how can animals be made of glass? Well, glass is formed from a substance called silica. The sponges use the silica found in ocean waters to build glass structures that will give them shape and support. Be careful! Some of the fragile creatures are up to 200 years old.When sponges die, new ones grow on top of the pile of old ones. Over centuries, a massive and complex reef takes shape. Some sponges look like wrinkled trumpets, while others look like overgrown cauliflower or mushrooms.Dr. Paul Johnson, who discovered the Washington reef in 2007, also found other surprises such as bubbles of methane(甲烷) gas flowing out of the seafloor nearby. The methane feeds bacteria, and the bacteria feed the glass sponges.“It’s a new ecosystem we know nothing about,” said Dr. Johnson.The reef of yellow and orange glass sponges is crowded with crabs, shrimp, starfish, worms, snails, and rockfish. The glass reef is also a nursery for the babies of many of these creatures and was called a “kindergarten” by scientists.Many animals that live in the reef hang around for a long time, just like the sponges. Rockfish, for example, live for more than 100 years. Scientists are just beginning to study all the species that call the reef home.The Washington coast isn’t the only place where a living glass reef has been found. The first was discovered in Hecate Strait off the coast of British Columbia in 1991. Scientists all over the world were stunned to see it.【文章大意】本文主要讲述了科学家们在海底世界发现的奇观。
