广西高考英语阅读训练附答案
广西高考英语阅读训练原文History is full of cases where dreams have been a pathway to creativity and discovery. A striking example is provided by Dr. Otto Loewi, a pharmacologist (药理学家) and winner of a Nobel Prize. Loewihad spent years studying the chemical transmission of nerve impulses (脉搏). A tremendous breakthrough in his research came when he dreamed ofan experiment three nights in a row. The first two nights he woke up and wrote down the experiment quickly and untidily on paper. But the next morning, he cou ldn’t tell what the notes meant. On the third night, he got up after having the dream. This time, instead of making notes hewent straight to his laboratory and performed the important experiment. Loewi later said that if the experiment had occurred to him while awake he would have rejected it.Loewi’s experiment gives some insight into using dreams to produce creative solutions. Nervous feelings are reduced during dreaming, which may be especially useful in solving problems that require a fresh point of view.Being able to take advantage of dreams for solving is improvedif you “set” yourself before retiring. Before you go to bed, try to think intently about a problem you wish to solve. Bury yourself in the problem by stating it clearly and reviewing all relevant information. Then use the suggestions listed in the previous section to catch your dreams. Although this method is not guaranteed to produce a novelsolution or a new insight, it is certain to be an adventure. About half of a group of college students using the method for a week recalled a dream that helped them solve a personal problem.广西高考英语阅读训练题目44. The main idea of this passage is that _________.A. very little is really known about the meaning of dreamsB. it is possible to “catch”one’s dreams by planning before going to sleepC. dreams can be useful in producing creative solutions toone’s problemsD. Loewi’s experiment helped in the study of transmission of nerve impulses45. The first paragraph is mainly organized by _________.A. classifying types of experimentsB. summarizing the work of one researcherC. comparing and exploring historical casesD. telling in time order about one man’s research46. If Loewi had thought of the experiment while awake, he would have _________.A. asked someone else to do itB. thought it was a bad ideaC. tried it out on his ownD. thought it was a wise idea47. The author probably thinks that _________.A. nervous feelings may stop someone thinking of useful ideasB. dreaming is of very little value to most peopleC. Loewi should not have conducted his experimentD. college students should not try out dream experiments广西高考英语阅读训练答案44.C. 主旨大意题。

阅读下列材料，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
Love, success, happiness, family and freedom----how important are these values to you? Here is one interview which explores the fundamental questions in life. Question: Could you introduce yourself first? Answer: My name is Misbah, 27 years old. I was born in a war-torn area. Right now I'm a web designer. Q: What are your great memories? A: My parents used to take us to hunt birds, climb trees, and play in the fields. For me it was like a holiday because we were going to have fun all day long. Those are my great memories. Q: Does your childhood mean a lot to you? A: Yes. As life was very hard, I used to work to help bring money in for the family. I spent my childhood working, with responsibilities beyond my age. However, it taught me to deal with problems all alone. I learnt to be independent. Q: What changes would you like to make in your life? A: If I could change something in my life, I'd change it so that my childhood could have taken place in another area. I would have loved to live with my family in freedom. Who cares whether we have much money, or whether we have a beautiful house? It doesn't matter as long as I can live with my family and we are safe. Q: How do you get along with your parents? A: My parents supported me until I came of age. I want to give back what I've got. That's our way. But I am working in another city. My only contact with my parents now is through the phone, but I hate using it. It filters(过滤) out your emotion and leaves your voice only. My deep est feelings should be passed through sight, hearing and touch.( ) 1. In Misbah's chi ldhood, _______________.A. he was free from worryB. he liked living in the countrysideC. he was fond of getting close to natureD. he often spent holidays with his family( ) 2.

By chatting on the Internet.B. By calling them sometimes.C. By paying weekly visits.D. By writing them letters. ( ) 4. If there were only one question le ft, what would it most probably be?A. What was your childhood dream?B. What is your biggest achievement?C. What is your parents' view of you?D. What was your hardest experience in the war?【语篇解读】本文通过一个采访,把Misbah 这个人的生活,成长呈现给我们.1. 答案C 【解析】细节理解题.由My parents used to take us to hunt birds, climb trees, and play in the fields. For me it was like a holiday because we were going to have fun all day long. Those are my great memories.可知,Misbah 宠爱大自然.所以答案选C 项.2. 答案C 【解析】推理推断题. 依据文中I would have loved to live with my family in freedom. Who cares whether we have much money, or whether we have a beautiful house? It doesn't matter as long as I can live with my family and we are safe.可知,作者憧憬和平自由的生活.故选C 项.3. 答案C 【解析】细节理解题. 依据My only contact with my parents now is through the phone, but I hate using it. It filters out your emotion and leaves your voice only. My deepest feelings should be passed through sight, hearing and touch. 可知, Misbah 厌烦在电话里与父母联系,由于它只剩下了声音,而Misbah 想要的是与父母面对面的沟通.四个选项中只有 C 项能够让Misbah 与父母面对面.由此推断选 C 项.4. 答案B 【解析】推理推断题.其它三个问题在上文中都有所涉及,只有B 项没有.所以假如还剩一个问题,很有可能就是 B 项.阅读理解。
广西桂林市师范大学附属外国语学校2021年高考英语高考英语压轴题 阅读理解专项训练分类精编附解析
广西桂林市师范大学附属外国语学校2021年高考英语高考英语压轴题阅读理解专项训练分类精编附解析一、高考英语阅读理解专项训练1．阅读理解By analyzing the fossilized teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants (婴儿) for longer periods than their contemporary relatives.The results, published in the journal Science Advances, provide a first insight into the practice of weaning (断奶)that remain otherwise unseen in the fossil record.The team sampled minute amounts from nearly 40 fossilized teeth of our South African fossil relatives, early Homo, Paranthropus robustus and Australopithecus africanus. They measured the proportions of their stable calcium isotopes (同位素）in the tooth enamel(牙釉质), which are a function of the mother milk intake by infants. They show that early Homo offspring(后代) was breastfed in significant proportions until the age of around three to four years, which likely played a role in the apparition of traits that are specific to human lineage(血统), such as the brain development.In contrast, infants of Paranthropus robustus, that became extinct around one million years ago and were a more robust species in terms of dental anatomy, as well as infants of Australopithecus africanus, stopped drinking sizeable proportions of mother milk in the course of the first months of life.These differences in nursing behaviors likely come with major changes in the social structures of groups as well as the time between the birth of one child and the birth of the next.One of the study's lead authors, Dr Theo Tacail said: "The practice of weaning -- the duration of breastfeeding, age at non-milk food introduction and the age at cessation of suckling -- differs among the modern members of the hominid family which includes humans and modern great apes: orangutan, gorillas, chimpanzees and bonobos.The development of such behavioral differences likely played major roles in the evolution of the members of human lineage, being associated for instance with size and structure of social groups, brain development.However, getting insights into these behavioral changes from fossils that are millions of years old is a challenge and, so far, little evidence allow discussing nursing practices in these fossil species.The findings stress the need for further exploration of calcium stables isotopes compositions in the fossil record in order to understand the co-evolution of weaning practices with other traits such as brain size or social behaviors."/first-human-ancestors-breastfed-for-longer-than-contemporary-relatives/https:///releases/2019/08/190829115427.htm（1）What do we know the findings of the team?A. It takes the lead in focusing on Practice weaning.B. It has disclosed the link between the weaning practice and other traits.C. It is evident that nursing practice is associated with behavioral changes.D. It's contemporary humans that spend more time breastfeeding their infants.（2）What does the underlined phrase "such behavioral differences" in Paragraph 7 most probably refer to?A. Differences in the calcium isotope in the teeth.B. Differences in the social structure of groups.C. Differences in the practice of weaning.D. Differences in the change of behaviors.（3）What does the passage mainly talk about?A. The evolution of human lineage.B. The possible influence of nursing behaviors.C. The exploration of compositions in the fossil.D. The function of mother milk at the age of infants.【答案】（1）A（2）C（3）B【解析】【分析】本文是一篇说明文，通过对祖先牙齿化石的研究，科学家们发现第一批用母乳喂养婴儿的人类比同时代的其他的近亲在时间上要长很多，而这种育幼差异可能在人类进化中扮演了重要角色，比如大脑发育和社会群体方面。

“My husband is the worst page turner,” she laughed. “He’s interested in the music, feeling every note, and I have to say: ‘Turn, turn!’ “Robert is the best page turner I’ve had in my entire life.”
2.【2021·新高考I卷，B】
By day, Robert Titterton is a lawyer. In his spare on stage beside pianist Maria Raspopova — not as a musician but as her page turner. “I’m not a trained musician, but I’ve learnt to read music so I can help Maria in her performance.”
Mr Titterton is chairman of the Omega Ensemble but has been the group’s official page turner for the past four years. His job is to sit beside the pianist and turn the pages of the score so the musician doesn’t have to break the flow of sound by doing it themselves. He said he became just as nervous as those playing instruments on stage.
2021届高考英语复习日常阅读理解练习 课文原文及及练习含答案
There is something to be said for being a generalist, even if you are a specialist. Knowing a little about a lot of things that interest you can add to the richness of a whole, well-lived life. Society pushes us to specialize, to become experts. This requires commitment to a particular occupation, branch of study or research. The drawback to being specialists is we often come to know more and more about less and less. There is a great deal of pressure to master one’s field. You may pursue training, degrees, or increasing levels of responsibility at work. Then you discover the pressure of having to keep up.Some people seem willing to work around the clock in their narrow specialty. But such commitment can also weaken a sense of freedom. These specialists could work at the office until ten each night, then look back and realize they would have loved to have gone home and enjoyed the sweetness of their family and friends, or traveled to exciting places, meeting interesting people. Mastering one thing to the exclusion (排除) of others can hold back your true spirit.Generalists, on the other hand, know a lot about a wide range of subjects and view the whole with all its connections. They are people of ability, talent, and enthusiasm who can bring their broad perspective (视角) into specific fields of expertise (专长).The doctor who is also a poet and philosopher is a superior doctor, one who can give so much more to his patients than just good medical skills.Things are connected. Let your expertise in one field fuel your passions in all related areas. Some of your interests may not appear to be connected but, once you explore their depths, you discover that they are. My editor Toni, who is also a writer, has edited several history books. She has decided to study Chinese history. Fascinated by the structural beauty of the Forbidden City as a painter, she is equally interested to learn more about Chinese philosophy. “I don’t know where it will lead, but I’m excited I’m on this pursuit.”These expansions into new worlds help us by giving us new perspectives. We begin to see the interconnectedness of one thing to another in all aspects of our life, of ourselves and the universe. Develop broad, general knowledge and experience. The universe is all yours to explore and enjoy.课后练习1. To become a specialist, one may have to _____.A. narrow his range of knowledgeB. avoid responsibilities at workC. know more about the societyD. broaden his perspective on life2. The specialists mentioned in Paragraph 3 tend to _____.A. treasure their freedomB. travel around the worldC. spend most time workingD. enjoy meeting funny people3. According to the author, a superior doctor is one who _____.A. is fully aware of his talent and abilityB. is a pure specialist in medicineC. should love poetry and philosophyD. brings knowledge of other fields to work4. What does the author intend to show with the example of Toni?A. Passion alone does not ensure a person’s success.B. In-depth exploration makes discoveries possible.C. Everyone has a chance to succeed in their pursuit.D. Seemingly unrelated interests are in a way connected.5. What could be the best title for the passage?A. Be More a Generalist Than a SpecialistB. Specialist or Generalist: Hard to DecideC. Turn a Generalist into a SpecialistD. Ways to Become a Generalist拓展练习假定英语课上你们班就“Whether we should become a specialist or a generalist”这一话题展开了讨论。
广西省北海市2021高考英语阅读明白得巩固全程训练（2）
广西省北海市2021高考英语阅读明白得巩固全程训练（2）及答案【湖北省2021高考英语《考试大纲》调研卷二模试题】BAmerican students' concern for freedom lies in two patterns of behavior that Chinese students often notic e: an unwillingness to make social commitments and vague and changing definitions in acquaintanceships, friendships and dating relationships.American students tend to make social commitments only at the last minute. Many Americans want to have the freedom to do what they want,when they want, in order to maximize their chance of having "fun". Chinese students sometimes feel frustrated by this. They feel personally insulted because they interpret it as a sign that the Americans are not truly interested in them. However, this behavior is often a sign of valuing personal freedom, rather than a reflection of their feelings about other people.The Americans' vague and changing definitions about acquaintances and friendships also puzzle Chinese students. American students use the term "friend" very loosely. They might have one or more friends whom they call "friends with benefits". This fluidity (不稳固性) in relationship definitions can be very puzzling to someone from a culture that values clearly defined relationships between people.American college students have "parties" to socialize. The typical American party consists of people talking in small groups or pairs while drinking alcoholic beverages and perhaps snacking on some dry food or " chips and dip" . Loud music may be playing. Department receptions and parties often feature beer or wine.Many of the people at these parties may be strangers to each other. When invited to a party, Americans are relatively unlikely to ask, "Who will be there?" They are accustomed to meeting strangers and starting conversations with them. The parties usually do not include games or large-group interactions. So individuals must take the initiative to introduce themselves to strangers and talk with them.Many Chinese students find these parties boring or stressful. Chinese tend to be more accustomed to dinners as a way to get together with friends or acquaintances. Few, if any strangers, will be at a dinner. The atmosphere may be quieter and conversations deeper than at a typical American student party.55. Why do American students make social commitments only at the last minute?A. Because they fear to be frustrated by irresponsible promises.B. Because they are cautious about maki ng friends.C. Because they are always busy attending parties.D. Because they want to make the most of every possible chance to have fun.56. A Chinese student will feel upset with an American student because he thinks _____.A. the American student should make an earlier commitmentB. the American s tudent is not really interested in himC. the American student doesn't consider his feelingsD. the American student wants to squeeze fun out of their sufferings57. Why are Americans unlikely to ask who will attend the party when invited?A. Because they are used to meeting new people at the party.B. Because they regard it as a chance to make more friends.C. Because they care more about the food and drink served at the party.D. Because they tend to get together with friends.58. How will Chinese students feel when they attend a party where there are many strangers?A. Many of them will feel stressed.B. They will see it as a chance to meet new friends.C. They will feel free to talk with strangers.D. They will make the most of their chance of having fun.【解题导语】本文介绍了美国大学生的交友特点——崇尚个人自由，他们的朋友来得快去得也快，但他们坦率、易交往。

阅读下列材料，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
One evening in February 2007. A student named Paula Ceely brought her car to a stop on a remote in Wales. She got out to open a metal gate that blocked her path . That's when she heard the whistle sounded by the driver of a train. Her Renault Clio parked across a railway line. Second later, she watched the train drag her car almost a kilometre down the railway tracks.Ceely's near miss made the news because she blamed it on her GPS device(导航仪).She had never driven the route before .It was dark and raining heavily. Ceely was relying on her GPS. But it made no mention of the crossing. "I put my complete trust in the device and it led me right into the path of a speeding train," she told the BBC.W ho is to blame here? Rick Stevenson, who tells Ceely's story in his book When Machines Fail US, finger at the limitations of technology. We put our faith in digital devices, he says, But our digital helpers are too often not up to the job. They are filled with small problems. And it’s not just GPS devices: Stevenson takes us on a tour of dig ital disasters involving everything from mobile phones to wireless key boards.The problem with his argument in the book i s that it’s not clear why he only focuses digital technology, while there may be a number of other possible causes. A map-maker might have left the crossing off a paper map. Maybe we should blame Ceely for not paying attention. Perhaps the railway authorities are at fault for poor signaling system. Or maybe someone has studied the relative dangers and worked out that there really is something specific wrong with the CPS equipment. But Stevenson doesn’t say.It’s a problem that runs through the book. In a section on cars, Stevenson gives an account of the advanced techniques that criminals use to defeat computer-based locking systems for cars. He offers two independent sets of figures on car theft; both show a small rise in some parts of the country. Hesa ys that once once again not all new locks have proved reliable. Perhaps, but maybe it’s also due to the shortage of policemen on the streets. Or changing social circumstances. Or some combination of these factors.The game between humans and their smart devices is complex. It is shaped by economics and psychology and the cultures we live in. Somewhere in the mix of those forces there may be way a wiser use of technology.If there is such a way, it should involve more than just an awareness of the shortcomings of our machines. After all, we have lived with them for thousands of years. They have probably been fooling us for just as long.( ) 1 .What did Pa ula Ceely think was the cause of her accident?A. She was not familiar with the road.B. It was dark and raining heavily then.C. The railway works failed to give the signal.D. Her GPS device didn’t tell her about the crossing( ) 2. The phrase “near miss” (paragraph 2) can best be replaced b y _______.A. close bi tB. heavy lossC. narrow escapeD. big mistake( ) 3. Which of the following would Rick S tevenson most probably agree with?A. Modern technology is what we can’t live without.B. Digital technology often falls short of out expectation.C. Digital devices are more reliable than they used to be.D. GPS error is not the only cause for Celery’s accident.( ) 4. In the writer’s opinion, Stevenson’s argument i s________.A. one-sidedB. reasonableC. puzzlingD. well-based( ) 5.What is the real concern of the writer of this article?A. The major causes of traffic accidents and car thefts.B. The relationship between humans and technologyC. The shortcomings of digital devices we use.D. The human unawareness of technical problems.【参考答案】1---5、DCBAB阅读理解。

2021年广西高考英语总复习：阅读理解1．Transport has a lot to answer for when it comes to harming the planet．While cars and trains are moving towards greener，electric power，emissions from air travel are expected to increase massively by 2050．If we want big green sky solutions，we need blue sky thinking．Fortunately，there's plenty of that happening right now，particularly the short﹣haul flights powered by batteries．Harbour Air is the largest seaplane airline in North America，flying 30，000 commercial flights in 40 seaplanes each year．Significantly，all Harbour Air routes last less than 30 minutes，making it perfectly fit for electric engines．"As an airline，we're currently in the process of turning all our planes into electric airplanes．" says CEO Greg McDougall．To make this happen，the airline has partnered up with MagniX to create the world's first commercial flight with an electric engine．Making the skies electric isn't just good for the environment，it also makes sound financial sense：a small aircraft uses ﹩400 on conventional fuel for a 100﹣mile flight，while an electric one costs ﹩8﹣12 for the same distance，and that's before you factor in the higher maintenance costs of a traditional engine．There's also the added bonus that electric planes are just much more pleasant to fly in．No loud engine noise，no smell of fuel，just environmentally friendly peace and quiet．While there has been real progress in the e﹣plane industry，the technical challenges that remain are keeping everyone's feet firmly on the ground．A battery，even a lithium one，only provides 250 watt﹣hours per kilogram；compare this to liquid fuel，which has a specific energy of 11，890 watt﹣hours per kilogram．Carrying adequate batteries，however，would make the plane too heavy to get off the ground．In aircraft，where every bit of weight counts，this can't just be ignored．The transition（过渡）from gas to electric in the automobile industry has been made easier by hybrids﹣vehicles powered by both fuel and electricity．Many believe the same pattern could be followed in the air．Fuel consumption could be reduced as the electric component is switched on at key parts of the journey，especially on take﹣off and landing．It's certainly an exciting time for electric flying．With companies like Harbour Air takingthe lead，battery﹣powered planes，especially on short﹣haul journeys，are set to become a reality in the next few years．（1）According to Para.1，what is happening in air transport？CA．New explorations of the sky are being launched．B．Pollution caused by batteries is being controlled．C．Efforts are being made to make air travel greener．D．Demand for short﹣haul flights is increasing massively．（2）Why is Harbour Air fit for electric flights？AA．It runs short routes．B．It has a strong partner．C．Its planes can land on the sea．D．It has planes with powerful engines．（3）The expression "added bonus" refers to the fact that electric planes C．A．give passengers more pleasant viewsB．bring airlines more financial benefitsC．offer more enjoyable flying experiencesD．cost less in maintenance than traditional ones（4）What might be the biggest challenge of electric flying？DA．To improve the ground service for e﹣planes．B．To find qualified technicians for e﹣plane industry．C．To calculate the energy needed to power e﹣planes．D．To balance power and weight of batteries in e﹣planes．（5）What could be done during the transition from gas to electric in air flight？CA．To produce new electric components．B．To increase battery consumption．C．To use mixed﹣power technology．D．To expand the landing field．（6）What is the author's attitude towards the prospect of electric flying？CA．Short﹣sighted．B．Wait﹣and﹣see．C．Optimistic．D．Skeptical．【解答】（1）C．推理判断题．根据第一段中If we want big green sky solutions，we need blue sky thinking．Fortunately，there's plenty of that happening right now，particularly the short﹣haul flights powered by batteries．（如果我们想要大的绿色天空解决方案，就需要蓝天思维．幸运的是，现在有很多这样的情况发生，尤其是靠电池供电的短途飞行）由此判断出，人们正在努力使航空旅行更加环保．故选C．（2）A．细节理解题．根据第二段Harbour Air is the largest seaplane airline in North America，flying 30，000 commercial flights in 40 seaplanes each year．Significantly，all Harbour Air routes last less than 30 minutes，making it perfectly fit for electric engines．可知Harbour Air 是北美最大的水上飞机航空公司，每年有40架水上飞机搭载3万次商业航班．值得注意的是，所有港口航线的飞行时间都不到30分钟，这使得它完全适合于电动引擎．也就是说Harbour Air的飞行航线短，这使电动飞行成了可能．故选A．（3）C．猜测词义题．根据下文that electric planes are just much more pleasant to fly in．No loud engine noise，no smell of fuel，just environmentally friendly peace and quiet．电动飞机没有发动机的噪音，没有燃油的味道，只有环保的宁静等优点，为乘坐电动飞机的乘客提供更愉快的飞行体验．所以added bonus指的是乘客获得的更愉快飞行体验的额外收获，故选C．（4）D．推理判断题．根据倒数第三段A battery，even a lithium one，only provides 250 watt﹣hours per kilogram；compare this to liquid fuel，which has a specific energy of 11，890 watt﹣hours per kilogram．Carrying adequate batteries，however，would make the plane too heavy to get off the ground．In aircraft，where every bit of weight counts，this can't just be ignored．可知电池不能提供足够的燃料，而携带足够的电池会使飞机太重而无法起飞．在飞机上，每一点重量都很重要，不能忽视．由此推知平衡电动飞机电池的功率和重量是电动飞机面临的最大挑战，故选D．（5）C．细节理解题．根据倒数第二段The transition （过渡）from gas to electric in the automobile industry has been made easier by hybrids﹣vehicles powered by both fuel and electricity．可知从燃料飞行到电动飞行过渡过程中，可以使用燃料和电力混合动力技术．故选C．（6）C．情感态度题．根据最后一段It's certainly an exciting time for electric flying．With companies like Harbour Air taking the lead，battery﹣powered planes，especially on short ﹣haul journeys，are set to become a reality in the next few years．可知电动飞行无疑是激动人心的，电动飞行短途旅行将在未来几年内成为现实．由此判断出作者对电动飞行的前景是乐观的，A．Short﹣sighted短视的，目光短浅的．B．Wait﹣and﹣see观望的．C．Optimistic乐观的．D．Skeptical怀疑的．故选C．2．Wild Track is an organization that aims to protect endangered animals like rhinos．They use a computer program that runs photos of animal tracks through an algorithm （演算法）．Then the program makes the same observations as a tracker would，allowing scientists to know where individual animals go．However，the program itself needs "training"．It starts with collecting good photos of prints from endangered animals in captivity （圈养）．As people send in photos of tracks from animals in the wild，the FIT program can compare it to tracks from animals it "knows．" As the program becomes more accurate，Wild Track hopes it will become a major tool for monitoring any endangered species．Anyone can help Wild Track by taking images of tracks and sending them to a partner organization called naturalist．org．The only tool you need is a digital camera or cellphone．After finding a clear track，place one ruler along the bottom of the footprint and another along the left side．Below the footprint，place a note containing your exact name and the date．Holding
