高一英语阅读理解专项训练及答案及解析一、高中英语阅读理解1.阅读理解Last week, Vodafone started a test of the UK's first full 5G service, available for use by businesses in Salford. It is part of its plan to trial the technology in seven UK cities. But what can we expect from the next generation of mobile technology?One thing we will see in the preparation for the test is lots of tricks with the new tech. Earlier this year, operators paid almost £ 1.4 billion for the 5G wavelengths, and to compensate for that cash, they will need to catch the eye of consumers. In September, Vodafone used its bit of the range to display the UK's first hologram (全息) call. The Manchester City captain Steph Houghton appeared as a hologram in Newbury. It isn't all holograms, however: 5G will offer faster internet access, with Ofcom (英国通讯管理局) suggesting that video that takes a minute to download on 4G will be available in just a second.The wider application is to support connected equipment on the "internet of things" -not just the internet-enabled fridge that can reorder your milk for you, but the network that will enable driverless cars and delivery drones (无人机) to communicate with each other.Prof William Webb has warned that the technology could be a case of the emperor's new clothes. Much of the speed increase, he claims, could have been achieved by putting more money in the 4G network, rather than a new technology. Other different voices have suggested that a focus on rolling out wider rural broadband access and addressing current network coverage would be more beneficial to the UK as a whole.Obviously, 5G will also bring a cost to consumers. It requires a handset for both 5G and 4G, and the first 5G-enabled smart phones are expected in the coming year. With the slow pace of network rollout so far, it is likely that consumers will end up upgrading to a new 5 G phone well before 5 G becomes widely available in the next couple of years.(1)Why does Prof William Webb say "the technology could be a case of the emperor's new clothes"?A. He is in favor of the application of the new technology.B. 5G will bring a cost to consumers in their daily life.C. 5G helps people communicate better with each other.D. He prefers more money to be spent on 4G networks.(2)The underlined word "addressing" in the fourth paragraph has the closest meaning to________. A. making a speech to B. trying to solve C. managing to decrease D. responding to(3)The last paragraph indicates that .A. it'll take several years .to make 5G accessible to the public in the UKB. 5G service shows huge development potential and a broad marketC. customers are eager to use 5G smart phones instead of 4G onesD. it's probable that 5G network rollout is speeding up in Britain(4)What do we know about the text?A. Vodafone is successful in spreading the 5G service.B. Steph Houghton appeared as a hologram by 4G.C. The application of 5G will make life much easier.D. 5G phones are available in rural areas of the UK.【答案】(1)D(2)B(3)A(4)C【解析】【分析】本文是一篇说明文。

【英语】高一英语阅读理解解题技巧及练习题(含答案)及解析一、高中英语阅读理解1.阅读理解No poem should ever be discussed or "analyzed", until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it. All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling 'interpretation' of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching cannot replace the student and teacher reading it or, best of all, reciting it.I have come to think, in fact, that time spent reading a poem aloud is much more important than "analyzing" it, if there isn't time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is "a criticism of life", "a heightening of life, enjoyment with others". It is "an approach to the truth of feeling", and it "can save your life". It also deserves a place in the teaching of language and literature more central than it presently occupies.I am not saying that every English teacher must teach poetry. Those who don't like it should not be forced to put that dislike on anyone else. But those who do teach poetry must keep in mind a few things about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it.(1)The passage indicates that analyzing a poem is .A. not essential at allB. a preparation for appreciating itC. an approach to understanding itD. optional in class sometimes(2)The recitation of a poem by the teacher or a student in the classroom .A. is the best way to understand itB. easily arouses some discussion among the studentsC. helps the teacher to analyze itD. can not take the place of the poet reading it(3)Which of the following statements may the author agree with?A. The most important teaching goal is to have students read and recite every poem they learn.B. Poetry is the foundation of all languages and literature courses.C. The teaching of poetry should have been much more stressed.D. Every English teacher is supposed to convey their love of poetry to their students.【答案】(1)D(2)A(3)C【解析】【分析】本文是一篇议论文,作者阐述了诗歌教学的重要性。

There are certain characteristics that distinguish these people from one another. And the characteristics also help guide directors towards what is going to be the next big cinematic presentation.The RegularsThey are basically amateur movie critics themselves due to the amount of movies they watch. They do not decide more between movies and can generally see two or even three in one sitting. So older people are the regulars due to their plenty of free time they have.The Young ParentsChildren's movies are their entertainment of choice, and they tend to choose light-hearted humor over everything. Usually friendly, this group are great at socializing. As for the movie category for children, directors trust this group as they know what is wanted and expected in the types of movies.The CoupleThey are quick to get into the cinema and usually buy what is required by the female partner. What is usually a similar theme in their movies is at least a hinting at a love story of some sort. These groups are excellent test subjects for the production of Nicholas Sparks type movies as they feel like their love story is the next big production and thus directors are drawn towards them.The Noisy TeensThese types can interrupt a movie countless times. Though they may buy tons of food, they seem somehow not to send the food into their mouths and employees find much food is left on the floor as if a food fight went on during the film. Action and adventure movies come out usually for this crowd because the plot and fast-paced nature of the film usually keep the teens at bay for that time period.(1)The text would most benefit ________.A.film loversB.movie directorsC.theater visitorsD.cinema bosses(2)What do we learn about the Couple?A.They are required to get into the cinema soon.B.Both of them enjoy movies of different themes.C.The female partner often decides what they see.D.They like to judge the quality of the love-story films.(3)Which group will probably pay little attention to the subject of the movie?A.The Regulars.B.The Young Parents.C.The Couple.D.The Rowdy Teens.(4)What kind of movies most likely attracts the teens?A.Light-hearted humor movies.B.Nicholas Sparks type movies.C.Exciting movies about the war.D.Romantic love-story movies.(5)What's the text mainly about?A.Analysis of movie theater goers.B.Movies for people with different tastes.C.Approaches to attracting audiences.D.The recipe to pick a popular movie.【答案】(1)B(2)C(3)A(4)C(5)A【解析】【分析】本文是一篇应用文,分析了四类电影观众的特征。

But making time to get outside in the sun, even when it's cold out, could have bigger mood benefits than you might realize.While the link between sunshine and mental health is nothing new, new research from Brigham Young University(BYU) has shown that the association may be even stronger than previously realized. It finds that sunlight exposure is by far the greatest weather-related factor determining mental health outcomes. In other words: more sunshine, more happiness.For the study, a psychologist, a physicist and a statistician from BYU teamed up to compare daily environmental data from the university's Physics and Astronomy Weather Station with emotional health data archived by day for 16,452 adult therapy patients who were being treated at the BYU Counseling and Psychological Services Center.Exposure to sunlight is a significant factor in seasonal affective disorder. Research has shown that the brain produces more of the feel-good neurotransmitter serotonin on sunny days than it does on darker days. What's more, lack of sunlight is linked with lower vitamin D levels, which in turn has been correlated with depression and low energy.If you're getting enough sun, your emotions should remain relatively stable, the researchers found. But as the amount of sunlight in the day is reduced, levels of emotional pain can soar. Other weather variables including temperature, pollution and rain were not found to have an impact on mental health."We were surprised that many of the weather and pollution variables we included in the study were not significantly correlated with clients' scores on the distress measure once we had accounted for suntime," Dr. Mark Beecher, a professor of psychology at the university and the study's lead author, told The Huffington Post. "People tend to associate rainy days, pollution, and other meteorological phenomena with sadness or depression, but we did not find that."(1)What does the author suggest we do in Paragraph 1?A.Realized the benefits of sunshine.B.Avoid hibernating in springtime.C.Curl up in a blanket in cold weather.D.Enjoy sunshine even in cold weather.(2)The underlined word "soar" in Paragraph 5 most probably means " "?A.Rise sharply.B.Vary unstably.C.Drop slightly.D.Change greatly.(3)What does the passage say about the research done by BYU?A.It is done on normal adults of various ages.B.It is carried out by Dr Mark Beecher alone.C.It concludes the sunshine means happiness.D.It finds that temperature affects mental health.(4)What can be inferred from the passage?A.Lower vitamin D levels are helpful in keeping us energeticB.The research findings are inconsistent with the popular belief.C.The more sunshine we get, the less excited we are likely to feel.D.The link between sunshine and mental health was unknown before.【答案】(1)D(2)A(3)C(4)B【解析】【分析】本文是一篇说明文,研究表明:阳光照射是影响心理健康结果的最重要的天气因素。

I enjoyed the feeling that comes from watching snow fall gently from heaven while I'm cosy inside with a good fire burning in the stove. But there were more serious concerns, like the lack of rainfall making our woods more accessible to summer forest fires. Local ski fields and hotels, all dependent on a snowy season, felt sorry for the vacant lifts, empty restaurants and unused snowmobiles.Then I happened to see three little robins (知更鸟) fly into our yard. What were they doing here? West of us, in the Willamette Valley, wild flowers burst this time of year. But here in central Oregon, even if a groundhog (土拨鼠) had wanted to appear, it couldn't have broken through the frozen earth. And yet, these robins had arrived.Their presence brought me a flow of happiness. It felt like a celebration as I dug into my bag of birdseed and spread a handful on the ground. Above me, the deep blue sky was cloudless, perfectly quiet but for some smoke from a neighbor's chimney. The lively cold made the air fresh and clean.My robins jumped lightly toward the seed. My soul jumped with them, feeling equally carefree. Caught up in the moment of spring fever, I checked our snowless flower beds. To my delight, I spotted a green branch sticking out through the brown soil.Despite the cold, I wasn't ready to go back inside. Just a short meeting with those robins had renewed my spirit. The next day I would return to my outdoor work with a cheerful heart and a hopeful eye for these signs of spring.(1)The author missed a snowy winter because snow could .A. prevent forest firesB. boom his businessC. promise an early springD. bring him a good feeling(2)The author felt happy when finding .A. the sky was deep blue with cloudsB. three little robins flew into his yardC. wild flowers burst in the Willamette ValleyD. a groundhog appeared through the frozen earth(3)We can infer from the passage that the author .A. would enjoy wild flowers the next dayB. thought winter was already overC. longed for the coming of springD. loved robins the most【答案】(1)D(2)B(3)A【解析】【分析】本文是一篇记叙文,寒冷的冬天,作者在家里发现有三只小知更鸟飞到了他的庭院,他感觉很高兴,于是他决定第二天外出,去寻找春天的足迹。

(英语)高一英语阅读理解解题技巧及练习题及解析一、高中英语阅读理解1.阅读理解We want our children to succeed, in school and, perhaps even more importantly, in life. But the paradox(悖论) is that our children can only truly succeed if they first learn how to fail. Consider the finding that world-class figure skaters fall over more often in practice than low-level figure skaters. At first sight this seems contradictory. Why are the really good skaters falling over the most?The reason is actually quite simple. Top skaters are constantly challenging themselves in practice, attempting jumps that stretch their limitations. This is why they fall over so often, but it is precisely why they learn so fast. Lower-level skaters have a quite different approach. They are always attempting jumps they can already do very easily, remaining within their comfort zone. This is why they don't fall over. In a superficial sense, they look successful, because they are always on their feet. The truth, however, is that by never failing, they never progress.What is true of skating is also true of life. James Dyson worked through 5,126 failed prototypes(原型) for his dual cyclone vacuum before coining up with the design that made his fortune. These failures were essential to the pathway of learning. As Dyson pu t it: “You can't develop new technology unless you test new ideas and learn when things go wrong. Failure is essential to invention.”In healthcare, however, things are very different. Clinicians don't like to admit to failure, partly because they have healthy egos(自我)(particularly the senior doctors) and partly because they fear litigation(诉讼). The consequence is that instead of learning from failure, healthcare often covers up failure. The direct consequence is that the same mistakes are repeated. According to the Journal of Patient Safety, 400,000 people die every year in American hospitals alone due to preventable error. Until healthcare learns to respond positively to failure, things will not improve. But let us return to children. One of the major mistakes in education in the 1970s was the attempt to equip children with confidence by giving them lots of successes (setting the bar very low). The consequence was that the ego of kids became bound up with success, and they became unable to take risks and collapsed as soon as they hit a proper challenge.We need to flip(翻转) this approach. In a complex world, failure is inevitable. It is those individuals and institutions that have the flexibility to face up to failure, learn the lessons and adapt which eventually excel(突出).(1)The question raised in the first paragraph is to ________.A. open up a discussion on the topicB. analyze the reason for successC. express the author's oppositionD. doubt the abilities of the top skaters(2)Which of the following is the structure of the passage?A. B. C. D.(3)What would be the best title for the passage?A. How we can avoid failure in lifeB. What we should learn from failureC. Why failure is the key to flying highD. Where we further improve ourselves【答案】(1)A(2)A(3)C【解析】【分析】本文是一篇议论文,论证了“失败是孩子成功的必须条件”这一观点。
(1)考查推理判断。
根据第一段中的“But the paradox(悖论)is that our children can only truly succeed if they first learn how to fail.”可知,文章的中心论点是如果孩子想要真正成功,首先就要学会失败。
后面以世界级滑冰运动员摔倒的次数更多来证明这一点,最后一句提出问题:为什么好的滑冰运动员反而摔倒的次数多呢?下文对这个问题做了回答,进一步阐明了文章的中心论点。
很明显,这个问题就是为了引出下文对中心论点的论述服务的。
故选A。
(2)考查文章结构。
第一段提出中心论点并以滑冰运动员为例引出第二段。
第三段James Dyson为正面例子证明:成功是建立失败的基础上的。
而第四和第五两段分别以医疗和20世纪七十年代的儿童教育为反例证明:不经历失败就不会获得成功和提高。
最后一段再次强调中心论点。
故选A。
(3)考查主旨大意。
文章第一段即提出中心论点:the paradox(悖论)is that our children can only truly succeed if they first learn how to fail,中间几段以正反两方面的例子证明了该论点。
最后一段又重新强调了该论点。
很明显,文章的中心意思就是:失败是孩子真正成功的必要条件。
故选C。
【点评】本题考点涉及推理判断,文章结构和主旨大意三个题型的考查,是一篇教育类阅读,要求考生根据上下文进行逻辑推理,概括归纳,从而选出正确答案。
2.阅读理解Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay comfortable in a cooler room. Or, picture a car windshield that stores the sun's energy and then releases it as heat to make the ice on the windshield disappear.According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.Solar energy is only available about half the time we need it — during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun's energy through a chemical reaction and releasing it later as heat.The key to enabling long-term, stable storage of solar heat, the team said, is to store it in the form of a chemical change rather than storing the heat itself. But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (触发)by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process.Such chemically-based storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solid-state films. The new approach is the first based on a solid-state material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.(1)What is the main purpose of Paragraph 1?A.To show the main idea of the passage.B.To practice readers' imagination.C.To interest readers in the passage.D.To introduce a new kind of material.(2)According to the passage, what can the polymer film do?A.It can be made into window glass.B.It can make necessary electricity.C.It can store energy and release sunshine.D.It can absorb sunshine and give off heat.(3)According to the passage, what is STF based on?A.The chemical reaction.B.The movement of heat.C.The form of electricity.D.The physical reaction.(4)What is the advantage of the molecular configuration?A.It is less expensive.B.It is very powerful.C.It is easily available.D.It is less changeable.【答案】(1)C(2)D(3)A(4)D【解析】【分析】本文是一篇说明文,介绍了一种新型材料,它可以通过自身吸热并储存热量,之后能够根据需要释放热。
