2021届洛阳市第三中学高三英语上学期期中考试试卷及答案解析
2021届洛阳市第三中学高三英语上学期期中考试试卷及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AWhen the weather is bad or when the flu breaks out, we can let the kids do some fun things at home, which can be beneficial to kids.Reading out loudIf your children are young enough, don't forget to read books to them out loud! Few children dislikehaving a good book read to them, and it's great for the development of their brains. However, if your children are a bit older and have moved onto more advanced books, there is always the choice of listening to an audiobook. This can also be done while they're doing something else.Playing board gamesMaybe your children's table is full of board games, which have been forgotten for a long time. It's a good time to bring them out when playing outside is no longer a choice. Surely, playing board games is a great way to connect with children. In addition, many board games are designed to get children thinking!Having a dance partyConsidering that all you need is a speaker or maybe just a phone, you can have a dance party wherever you are! This is a great way to get kids’ bodies moving when they are inside. Play some of your children's favorite music and let them dance to it. Not only is it good exercise, but it will help your children feel time is flying!Doing jigsaw (拼图) puzzlesFor most people that have children, it's common to have at least one jigsaw puzzle at home. Jigsaw puzzles are great because everyone can do them on their own time. Besides, your whole family will have a sense of achievement when everyone is smiling over the finished product.1. What do reading out loud and playing board games have in common?A. They both develop children's team spirit.B. They both improve children's listening ability.C. They both do good to children's thinking ability.D. They both focus on interaction between children.2. Which of the following combines exercise and music?A. Reading out loud.B. Playing board games.C. Doing jigsaw puzzles.D. Having a dance party.3. What is the purpose of the text?A. To list four interesting children's parties.B. To recommend four children's favorite books.C. To introduce some activities for children inside.D. To show some funny things for children outside.BThese days, football is one of the most popular sports in the world. Given that Neil Armstrong wanted to take a football to the Moon, we could even say that it is also the most popular sport out of this world! The history of the game goes back over two thousand years to Ancient China. It was then known as cuju (kick ball), a game using a ball of animal skins with hair inside. Goals were hung in the air. Football as we know it today started inGreat Britain, where the game was given new rules.That football is such a simple game to play is perhaps the basis of its popularity. It is also a game that is very cheap to play. You don’t need expensive equipment; even the ball doesn’t have to cost much money. All over the world you can see kids playing to their hearts’ content with a ball made of plastic bags.Another factor behind football’s global popularity is the creativity and excitement on the field. It is fun enough to attract millions of people. You do not have to be a fan to recognize the skill of professional players or to feel the excitement of a game ending with a surprising twist.What’s more, football has become one of the best ways for people to communicate: it does not require words, but everyone understands it. It breaks down walls and brings people together on and off the field.“Some people believe football is a matter of life and death, ...” said Bill Shankly, the famous footballer and manager. “I can tell you with certainty it is much, much more important than that.” This might sound funny, but one only has to think about the Earth to realize that our planet is shaped like a football.4. What can we know from paragraph one?A. Some people like to play football on the Moon.B. The game called cuju was given new rules today.C. Cuju is different from football as we know it today.D. Many people like playing a ball made of plastic bags.5. According to the author, there are ________ reasons why football became so popular in the world.A. 3B. 4C. 5D. 66. What can be inferred from the last paragraph?A. Football is round.B. Football is more than just a sport.C. Our planet is shaped like a football.D. What Bill Shankly said sounds funny.7. What’s the author’s purpose in writing the passage?A. To talk about the history of football.B. To express his/her love of football.C. To explain why football is such a popular game.D. To prove that he/she is a professional football fan.CWhen I was a boy, there was but one permanent ambition among my comrades in our village on the west bank of Mississippi River. That was, to be a steamboat man. We had temporary ambitions of other sorts, but they were only temporary.My father was a justice of the peace, and I supposed he possessed the power of life and death over all men and could hang anybody that offended him. This was distinction enough for me as a general thing；butthe desire to be a steamboat man kept intruding, nevertheless. One of our boys in town, who went away and was not heard of for-a long time, turned up as apprentice engineer on a steamboat. This thing shook the bottom out of all my Sunday—school teachings. That boy was notoriously worldly, and I was just the opposite. There was nothing generous about this fellow in his greatness. He would always manage to have a rusty nail to scrub while his boat stopped at our town, and he would sit on the inside guard and scrub it, where we could all see him. And wherever his boat was laid up he would come home and show off in the town in his blackest and greasiest clothes, so that nobody could help remembering that he was a steamboat man; and he used all sorts of steamboat technical terms in his talk, as if he were so used to them that he forgot common people could not understand them.This creature's career could produce but one result, and it was speedily followed. Boy after boy managed to get on the river. Despite many choices, pilot was the grandest position of all. The pilot, even in those days of trivial wages, had a princely salary—from 150—250 dollars a month, and no board payment.But our parents would not let us and our worry was the next year would find us hunting for jobs with low pay again. So by and by I ran away. I said I never would come home again till I was a pilot and could come in glory.8. Why does the writer mention his father's job in Paragraph 2?A. To show that his father was in power.B. To show that his father is cruel.C. To emphasize the job he prefers.D. To emphasize his love for his father.9. Which of the following can best conclude the writer's attitude toward the boy?A. He thought the boy was material but pitiful.B. He thought the boy was annoying but still envied him.C. He thought the boy was shallow but knowledgeable.D. He thought the boy was disrespectful but still liked him.10. Which of the following statements is Not True?A. The boy talked in a way to make others feel jealous.B. The boy's experience made other boys follow suit.C. The pilot's salary was ly high but without meals covered.D. The writer was ambitious to make his childhood dream come true.11. What rhetorical method does the underlined sentence have?A. Simile.B. Personification.C. Parallelism.D. Irony.DLight pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.Insect population collapses have been reported around the world, and the first global scientific review published in February,said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects areimportant prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.The researchers said most human-caused threats to insects have analogues in nature, such as climate changeand invasive species. But light pollution is particularly hard for insects to deal with.However, unlike other drivers of decline, light pollution is ly easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.12. What is discussed in the passage?A. Causes of declining insect populations.B. Consequences of insect population collapses.C. Light pollution: the key bringer of insect declines.D. Insect declines: the driver of the collapsed ecosystem.13. What is the 5th paragraph mainly about?A. How light travels in space.B. How light helps insects find food.C. How the food chain is interrelated.D. How light pollution affects insects.14. What does the underlined word"analogues"in Paragraph 6probably mean?A. Selective things.B. Similar things.C. Variations.D. Limitations.15. What is the purpose of the last paragraph?A. To offer solutions.B. To give examples.C. To make comparisons.D. To present arguments.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2021届洛阳市第三中学高三英语上学期期中考试试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AAlthough Adrian Wood had already sent her three oldest children off toWhiteOakElementary SchoolinEdenton,North Carolina, she was anxious when it was her youngest son Amos's turn to start classes.Adriansaid, “Sending Amos to school was such a different path. He was 3 when he started school. He had autism(自闭症)and he didn't speak."Amos struggled to make friends and fit in, but there was always one person there who was very happy to see him. Raymond Brown has worked at the school as a guard for the past 15 years. All of the students know and love him, and he's truly a friend to all. He started callingAdrian's son “Famous Amos” on day one. To the mom's surprise, Amos quickly began responding with a cheerful "Hey, Brown” whenever he saw him. "He wasn't even saying 'daddy' at home, so it was really something, "Adriansaid.“Amos is a hard friend to have,"Adrianexplained, "He takes a lot more than he gives and that's tough for children. But those kids saw that he was popular and loved, and they started fighting over who would get to hold Amos' hand on the way to the classroom. It meant so much to me that he was favored by the other children at school, and Mr. Brown had a big hand in that.”About a year ago, school officials nominated Mr. Brown forNorth Carolina's School Hero, a $20,000 prize. When the results came out and he didn't win,Adrianwas heartbroken. She couldn't let the disappointing results stand, so she took to Facebook and created an annual “Famous Amos” prize for Mr. Brown in their community. Her neighbors answered the call, donating $35,000 in just one week! Townspeople and school officials gathered in March to celebrate Mr. Brown and give him the money they'd raised. Principal Michelle handed him a giant check and thanked him for everything he does to help kids like Amos find their way.1. What madeAdrianworried?A. Her youngest son's bad behavior.B. Her family's heavy financial burden.C. Her youngest son's mental problem.D. Her three sons' poor performance at school.2. What change did Mr. Brown bring to Amos?A. Amos became a top student at school.B. Amos got more attention from other kids.C. Amos learned to share and care about others.D. Amos had a better relationship with his family members.3. What did Mr. Brown get in the end?A. The “Famous Amos” prize.B. A check from the local government.C.North Carolina's School Hero prize.D. A small donation from the community.BJerry Lawson had a love of science and invention from a very young age. And, with the support of his family and teachers, he took that love and helped change the world for billions of people, when he invented the modem video game cartridge.Both of Jerry's parents supported his love of science and invention. His father, a longshoreman, was a science fan and encouraged Jerry to always experiment with things. Jerry's first-grade teacher helped encourage him on his path to be someone influential similar to George Washington Carver, a great AfricanAmerican inventor. His first love in school was chemistry but he ended up liking electronics（电子学）even more.He earned an amateur ham radio license at age 13 and built his own radio station in his room, with an antenna hanging out of his window! Jerry earned money from fixing television sets, visiting people's homes for inhouse repair, and also working at local electronics stores. Jerry also made walkie-talkies and sold them to other kids. He spent many Saturdays at an electronics store that had all of the parts he needed for his inventions. He would use his small allowance and money he earned to buy parts to help fuel his inventions.When he was a young adult, Jerry joined Fairchild Semiconductor as an engineer. During this time, he created his own video arcade game（街机游戏），Demolition Derby, in his garage.A few years later, Jerry was asked to work on a secret project. Not even his boss was allowed to know what he was doing! What it turned out to be was that he was designing the Fairchild Channel F video gameconsole（游戏控制器）and leading the team that invented the video game cartridge. This was the first of its kind and enabled kids around the world to affordably play video games at home.Just like with automobiles，many advances have occurred since the inventionof video games. Video games are now one of the biggest forms of entertainment in the world. But all of this would not have been possiblewithout the vision, passion, and skill of Jerry Lawson and his learn.4. How did Jerry earn money when he was a teenager?A. By running his radio station.B. By selling television sets.C. By repairing things for others.D. By making electronic parts.5. Before Jerry's secret project, playing video games at home was_____.A. expensiveB. harmfulC. commonD. tiring6. What does the author mainly tell us in the last paragraph?A. Jerry Lawson and his team can be more skillful.B. Jerry Lawson is important to the game industry.C.Many advances have taken place in the automobile industry.D. Video games are now the most popular form of entertainment.7. What can be the best title for the text?A. Video Gaming-An Important IndustryB. Game Console-Key to Home Video GamesC. Jerry Lawson-Father of Modern GamingD. Support and Encouragement-Necessary for SuccessCSome years ago a young man applied to a large United States optical firm for a job as a lens designer. He apologized for lack of training, but on announcing that he owned two copies of the classic Conrady's Applied Optics and Optical Design, one for his office and a second for his bedside table, he was hired on the spot. Perhaps the story will be repeated some day with Buchdahl's Introduction to Hamiltonian Optics as a similar certificate of qualification.Hamiltonian theory describes with powerful generality the overall properties of optical systems considered as ‘black boxes’, although it does not describe the detailed structure needed to construct the systems and achieve these properties. Buchdahl's book is therefore on the subject of geometrical optics, but it is not about how to design lenses. It is, however a compact comprehensive account of the fundamentals of the theory written with the lens designer's needs very much in mind. Every lens designer worth his salt has at some time in his career attempted to apply the broad concepts of Hamiltonian optics to the solutions of practical problems. Success has been sufficiently rare that the theory, as such, has made little direct contribution to techniques for optical instrument design. The failures have been frustrating because of the obvious fundamental power of the theoryand because of its conceptual elegance. The indirect effects have been large, however, both in contributing to an understanding of fundamental principles that govern the overall behavior of optical systems and in pointing the way to other, more practical, theoretical approaches.Buchdahl approaches the subject not only as a capable mathematical physicist, but as one who with a knowledge of practical optics has made a significant contribution to geometrical optical theory. Buchdahl's approach has, over the last decade, had a major impact on modern lens design with computers. Thus, he brings to this exposition of Hamiltonian optics a familiarity with practical optics not usually found in authors on this subject.The author claims his book to be non-mathematical, and indeed it might be so viewed by a professional mathematician. From the point of view of many physicists and engineers, it will appear to be quite mathematical. Moreover, this is a tightly written book. The subject matter is developed with precision, and the author expects the reader, at very point, to be master of the preceding exposition.8. Hamiltonian theory met with failures as a result of ______.A. newer finding related to the wave particle nature of lightB. very complicated concepts too difficult to understand by most lens designersC. too much mathematical detail in the theoryD. not enough practical information offered by the theory to allow for use by lens crafters9. The author of this passage implies that Introduction to Hamiltonian Optics is necessary to ______.A. the students who are major in mathematical geometryB. those who want to grasp the basic principles of optical systemsC. the lens designers who look for instructions on practical designsD. those who are interested in physics10. The article points out that the great benefits of Hamiltonian optics have been found is ______.A. indirect ways of learning mathematicsB. a fundamental power within the theoryC. the conceptual elegance of the theoryD. the practical applications of the theory in finding new approaches to old problems11. This passage is probably excerpted from ______.A. a review of a bookB. a chemistry textbookC. an optician's essayD. a general science textDChina's Mars probe Tianwen-1 successfully landed on the surface of the red planet on May 15, 2021, leaving a Chinese footprint on Mars for the first time and in its first attempt, becoming the only other nation besides theUSto get such an achievement. The Tianwen-1 probe touched down at its pre-selected landing area in the southern part of Utopia Planitia, a wide plain on Mars, at 7:18 a.m.(Beijing Time), after three months scanning the whole planet on Mars docking orbit, the China National Space Administration(CNSA) announced.Tianwen-1, including an orbiter, a lander and a rover, was launched from the 'Wenchang Spacecraft Launch Site on the coast of southernChinas islandprovinceofHainanon July 23, 2020. It was the first step inChina's planetary exploration of the solar system, with the aim of completing orbiting, landing and roving on the red planet in one mission. According to the administration, the country's first Martian probe will conduct scientific investigations about the Martian soil, environment, atmosphere as well as water.China's planetary exploration program has been named “Tianwen”, which was named after a long poem by the famous ancient poet Qu Yuan. The name represents the Chinese nation's willpower in pursuing truth, the country's cultural inheritance of its understanding of nature and universe, as well as the unending exploration in science and technology.China's first Mars rover has been named “Zhurong”, which means the god of fire in an ancient Chinese story. The name indicates Chinese people's blessing for the rover to light the flame ofChina's planetary exploration. The rover has six wheels and four solar panels, and carries 13 scientific instruments. According to the CNSA, Zhurong has started its scientific exploration after moving from the landing platform onto the Red Planet's surface on May 22.More than 40 Mars missions have been launched since the 1960s, but only about half have succeeded. It is the first time in the world that orbiting, landing and roving on Mars has been completed in one launch mission, andChinahas come to the forefront of Mars exploration in the world.12. What can we learn from the first two paragraphs?A. China is the only nation to launch a probe to Mars.B. Tianwen-1 landed in the northern part of the planet.C. Tianwen-1 scanned the southern part of the planet.D. The Mars probe will carry out scientific investigations.13. How did the planetary exploration program get its name?A. From a long poem by Qu Yuan.B. From an ancient Chinese story.C. From Chinese nation's willpower.D. From theChinaNational Space Administration.14. Why does the author sayChinahas come to the leading position of Mars exploration?A. The rover carried many scientific instruments.B. China completed three tasks in one attempt.C. The rover successfully moved from the landing platform onto Mars.D. The CNSA is continuously exploring science and technology.15. What is the text mainly about?A. Tianwen-1 completed its mission.B. Tianwen-1 represented the god of fire.C. Tianwen-1 successfully landed on Mars.D. Tianwen-1 was launched from Wenchang.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2021年洛阳市第三中学高三英语上学期期中考试试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ASongkran, ThailandThis festival marks the Thai New Year, which is celebrated in the second week of April. This is the hottest time of the year in Thailand, so it makes sense that the biggest Songkran tradition is to throw water on people. Thais of all ages join in water fights, using buckets, hoses (软管)and water guns to celebrate the event.Boryeong Mud Festival, South KoreaDon't expect to come home clean after experiencing the Boryeong Mud Festival in South Korea. Famous for its mineral-rich mudflats, visitors rush to Boryeong in July to make themselves in mud, swim in grey pools and enjoy the party. There are even mudslides and a mud skiing competition for those who are seeking the extreme mud adventure!La Tomatina, SpainThe festival dates back to a parade in which some naughty teenagers knocked one performer off his stilts (高跷)and caused a fight of throwing vegetables accidentally. It was once banned until 1957 when the locals held a protest with a funeral. They carried a coffin containing a huge tomato as bands played a funeral march. In the following decades, La Tomatina has become a popular event. If you join the event, be aware that you squash (压扁) the tomato before throwing it. Have a great time but avoid causing any injury.Dia de los Muertos, MexicoBeginning at the midnight of October 31 and lasting through November 2,it is a festival when families gather together to remember those loved ones who have died, aiming to help them on their spiritual journey. On these days, Mexican families prepare special tables in their homes. On top of them they'll put photos of the dead and their favorite food. They also visit the graves of their beloved ones to show their respect to the dead.1.If you want to experience a special new year in a country, you can choose to visit ________.A.ThailandB.South KoreaC.SpainD.Mexico2.What may happen to you as a visitor in La Tomatina?A.You can perform stilts.B.Your can play funeral music in bands.C.You may be covered with mud.D.You may be attacked with tomatoes.3.Which festival is similar to the Tomb Sweeping Festival in China?A.Songkran.B.Boryeong Mud Festival. Tomatina.D.Dia de los Muertos.BParents and math teachers regularly asked by their school-aged charges whether math matters inreal life now have an answer.In a study published by the National Bureau of Economic Research this week, Harvard Kennedy School Policy Professor Joshua Goodman took a look at what happened to students whose high schools were required in the 1980s to increase the minimum level of coursework required to graduate. What he found is that the students were more likely to increase the number of math courses they took as a result of the change in standards and that translated into higher earnings down the line.Put simply: About 15 years after they graduated, the high school graduates who went to school when these changes took effect saw their average earnings increase about 10% for every extra year of math coursework. The findings may add fuel to the steady drum of education experts, policy makers and others calling for an increased focus on science and math education.The increase in required math courses didn’t necessarily produce rocket scientists, Goodman notes, because the extra coursework wasn’t at a particularly high level. But becoming familiar with and practicing ly basic math skills allowed high school graduates to pursue and excel at jobs that required some level of computational knowledge, he said.Goodman acknowledged that the earnings boost for the students connected with the up tick （上升）in math education may be dependent on the state of the economy. When Goodman checked in the late 1990s and early 2000s on the earnings of the students who graduated in the late 1985，he found that their earnings increased significantly if they took more math.4. What does Joshua Goodman’s study find?A. High school graduates earn more.B. High school students prefer math.C. Math matters a lot in one’s income.D. Math is a compulsory course in school.5. Why is increase in required math courses useful?A. It produced rocket scientists.B. It makes high school students smarter.C. It meets the requirements of the government.D. It enables high school graduates to get better jobs.6. What might be the author’s purpose in writing the text?A. To give a warning to policy makers.B. To seek help for high school students’ problems.C. To show the great importance of learning math.D. To tell a struggling history of high school students.7. What could be the best title for the text?A. Efforts matter mostB. Math makes moneyC. Earnings of different graduatesD. Changes of high school coursesCThe Native American of northern California were highly skilled at basketry, using the reeds, graeses, barks, and roots they found around them to fashion articles of all sorts and sizes-not only trays, containers, and cooking pots, but hats, boats, fish traps, baby carriers, and ceremonial objects.Of all these experts, none excelled the Pomo-a group who lived on or near the coast during the 1800's, and whose descendants continue to live in parts of the same region to this day. They made baskets three feet in diameter and othersno bigger than a thimble (顶针). The Pomo people were masters of decoration. Some of their baskets were completely covered with shell pendants；others with feathers that made the baskets’ surfaces as soft as the breasts of birds. Moreover, the Pomo people made use of more weaving techniques than did their neighbors. Most groups made al their basketwork by twining--the twisting of a flexible horizontal material, called a weft, around stiffer vertical strands of material, the warp. Others depended primarily on coiling-a process in which a continuous coil of stiff material is held in the desired shape with tight wrapping of flexible strands. Only the Pomo people used both processes with equal ease and frequency. In addition, they made use of four distinct variations on the basic twining process, often employing more than one of them in a single article.Although a wide variety of materials was available, the Pomo people used only a few. The warp was always made of willow, and the most commonly used weft was sedge root, a woody fiber that could easily be separated into strands no thicker than a thread. For color1 , the Pomo people used the bark of red-bud for their twined workand dyed bullrush root for black in coiled work. Though other materials were sometimes used, these four were the staples in their finest basketry.If the basketry materials used by the Pomo people were limited, the designs were amazingly varied. Every Pomo basket maker knew how to produce from fifteen to twenty distinct patterns that could be combined in a number of different.8. The word “fashion” in paragraph 1 is closest in meaning to ______.A. maintainB. organizeC. tradeD. create9. What is the author's main point in paragraph 2?A. The neighbors of the Pomo people tried to improve on the Pomo basket weaving techniques.B. The Pomo people were the most skilled basket weavers in their region.C. The Pomo people learned their basket weaving techniques from other Native Americans.D. The Pomo baskets have been handed down for generations.10. According to the passage, the relationship between red-bud and twining is most similar to the relationship between ______.A. bullrush and coilingB. weft and warpC. willow and feathersD. sedge and weaving11. Which of the following statements about Pomo baskets can be best inferred from the passage?A. Baskets produced by other Native Americans were less varied in design than those of the Pomo.B. Baskets produced by Pomo weaves were primarily for ceremonial and religious purposes.C. There were a very limited number of basket-making materials available to the Pomo people.D. The basket-making production of the Pomo people has been increasing over the years.DLight pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.Insect population collapses have been reported around the world, and the first global scientific review published in February,said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".There are thought to be millions of insect species, most still unknown to science, and about half are active at night.

Researchers say that getting older should not necessarily mean becoming more weak or sick. Their research shows that a devotion to a life of movement and exercise may help us live not only longer, but also healthier.For their study, the researchers looked at two groups. The first group was made up of 125 non-professional cyclists between the ages of 55 to 79. This group included 84 healthy men and 41 healthy women. We will call this group the “cyclists”.Researchers then found 130 people to make up a second group. Within this group, 75 people were aged from 57 to 80. The other 55 were between the ages of 20 and 36. The people in this group were also healthy, but they did not exercise regularly. We will call this group the “non-exercisers”. Smokers, heavy drinkers of alcohol and people with other health issues were not included in the study.Then, researchers gave both groups a series of tests. They tested their muscle mass (肌肉质量), muscular strength, percentage of body fat and the strength of their immune (免疫的) systems. Then the researchers compared the results of the two groups.Results showed that the cyclists did not experience body changes usually regarded as a normal aging process. For example, they did not lose muscle mass or muscular strength. Also, their body fat did not increase with age.The researchers also found something they had not expected. The study showed that the immune systems of the cyclists did not age either.The researchers advise us all to find an exercise that we like in our lives.4. How did the researchers carry out the study?A. By comparing.B. By discussing.C. By imagining.D. By reasoning.5. Which of the following is a result of the research?A. The cyclists kept a thin body shape.B. The non-exercisers gained weight easily.C. The cyclists’ muscles remained strong with age.D. The non-exercisers usually had health problems.6. Which is an unexpected result for the researchers?A. The cyclists had normal aging process.B. The cyclists’ immune systems didn’t age.C. The cyclists lost nearly all their fat.D. Everyone needed an exercise in their lives.7. Which of the following can be the best title for the text?A. Healthy People Need More ExerciseB. Take an Exercise, the Harder, the BetterC. Cycling Is the Best Way to Prevent AgingD. A Lifetime of Exercise Slows Aging ProcessCYou run into the grocery store to quickly pick up your item. You grab what you need and head to the front of the store. After quickly sizing up the check-out lines, you choose the one that looks fastest. You chose wrong. People getting in other lines long after you have already checked out and headed to the parking lot. Why does this seem to always happen to you?Well, as it turns out, it's just math that is working against you. A grocery store tries to have enough employees at the checkout lines to get all their customers through with minimum delay. But sometimes, like on a Sunday afternoon, they get super busy. Because most grocery stores don't have the physical space to add more checkout lines, their system becomes overburdened. Some small interruption — a price check, a particularly talkative customer — will have downstream effects, holding up the entire line behind them.If there are three lines at the store, these delays will happen randomly at different registers (收银台). Think about the probability. The chances of your line being that fastest one are only one in three, which means you have a two-thirds chance of not being in the fastest line. So it's not just in your mind: Another line is probably moving faster thanyours.Now, mathematicians have come up with a good solution, which they call queuing theory, to this problem: Just make all customers stand in one long snaking line, called a serpentine line, and serve each person at the front with the next available register. With three registers, this method is about three times faster on average than themore traditional approach. This is what they do at most banks, Trader Joe's, and some fast-food places. With a serpentine line, a long delay at one register won't unfairly punish the people who lined up behind it. Instead, it will slow everyone down a little bit.8. What phenomenon is described in the first paragraph?A. Queuing in a line.B. A shopping experience.C. A rush in the morning.D. Cutting in a line.9. According to the article, what may cause delays in checking out?A. The lack of employees in the grocery store.B. Some unexpected delays of certain customers.C. The increasing items bought by customers.D. A worsening shopping system of the store.10. What is the solution given by mathematicians?A. Employing more workers for checking out.B. Limiting the number of queuing people.C. Making only one line available.D. Always standing in the same line.11. What's the principle behind the queuing theory?A. To pursue the maximum benefit.B. To leave success or failure to luck.C. To avoid the minimum loss.D. To spread the risk equally among everyone.DToo much TV-watching can harm children’s ability to learn andeven reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs.A second study ,looking at nearly 1000 grown-ups in New Zealand, found lower education levels among 26-year-olds who had watched lots of TV during childhood.But the results don’t prove that TV is the cause and don't ride out that already poorly motivated youngsters (年轻人）may watch lots of TV.Their study measured the TV habits of 26-year-olds between ages5 and 15. These with college degrees hadwatch an averageof less than two hours of TV per week night during childhood, compared with an average of more than 2.5 hours for those who had no education beyond high school.In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest.While this study does not prove that bedroom TV sets caused the lower scores, it adds to increasing findings that children shouldn't have TVs in their bedrooms.12. According to the California study, the low-scoring group might _________.A. have had computers in their bedroomsB. not be interested in mathC. be unable to go to collegeD. have watched a lot of TV13. What is the researchers' understanding of the New Zealand study results?A. Poorly motivated 26-year-olds watch more TV.B. Habits of TV watching reduce learning interest.C. The connection between TV and education levels is difficult to explain.D. TV watching leads to lower education levels of the 15-year-olds.14. What can we learn from the last two paragraphs?A. TV sets shouldn't be allowed in children's bedrooms.B. Children should be forbidden from watching TV.C. More time should be spent on computers.D. Further studies on high-achieving students should be done15. What would be the best title for this text?A. Computers or TelevisionB. Effects of Television on ChildrenC.

2021-2022学年河南省洛阳市高三(上)期中英语试卷(附答案详解)
2021-2022学年河南省洛阳市高三（上）期中英语试卷一、阅读理解（本大题共14小题，共30.0分）AChildren under the age of 18 will be allowed up to three hours per week to play video games,according to a notice issued by China's National Press and Publication Administration.Online game companies are required to provide services to minors — from 8 to 9 p.m.on Fridays,Saturdays,Sundays and legal holidays — as a way to safeguard their physical and mental health.Children are playing more and more online games these days.Is it time to limit their online gaming time？What role do parents have？Readers share their opinions. RizlaredOnline games are addictive,but if children are taught how to manage in a sensible and responsible manner then it is no longer a threat（威胁）.To achieve this,parents need to set examples for not being glued to their phones.Teaching is and always will be the best solution to such problems.AndrewGood policy.By limiting time spent on online games,kids can spend time doing more useful things to develop their potential.They can go outside and run,jump and swim instead of sitting on a couch at home and playing with a smart phone.AdamIt is often seen that parents argue with children over cellphones.Most parents can hardly set and enforce the time limit for its daily usage.Some forcibly take away their cellphones,but it will ruin trust and relationship.Even worse,it will make their kids hate them.PinkExcessive（过度的）gaming is purely a waste of time and energy for minors and has a negative effect on both physical and mental health.The gaming industry should not put profit- flaking interests as its priority（优先事项） .They should act in a socially responsible way to provide an environment for children to ensure their well-being and development.LaurenThere would be a loophole（漏洞）.Children could use their parents' or other adults' IDs to avoidreal-name registration,thus making it impossible to put this policy in effect.Parents absolutely need to strengthen guidance and supervision to keep their children from gaming addiction.1.What should kids do according to Andrew？______A. Play online games.B. Play with a smart phone.C. Study all the time.D. Go in for outside activities.2.What does Pink advise the gaming industry to do？______A. Pay attention to its profit.B. Focus on kids' health.C. Be responsible for kids' surroundings.D. Persuade kids lo play more games.3.What role do parents have according to the passage？______A. They keep hold of their phones.B. They set examples for their kids.C. They limit their kids' time.D. They blame kids for addiction.BChris Rishworth is a travelling cyclist who would take photos along the journey.He regards it as killing three birds with one stone.Besides exercising,he can also improve his photography skills and raise money for the children in need through holding a photography show.In the past five years,Chris has raised more than one million dollars and helped more than 30 orphans（孤儿）complete primary and secondary school education.Chris' photographs have a very wide range of aspects,including impressive natural sceneries,attractive local conditions and customs,and mysterious historic sites,etc,but he believes the most heart-shaking one is the photo of a baby wallaby（沙袋鼠）.It was on August 5th when Chris was on his way to ride through Magnetic Island.Chris saw a helpless baby rock wallaby trying to get into its dead mother's pouch（育儿袋）.The deep brake marks and pieces of glass indicated that the mother wallaby was killed by a car.The sight shook his heart so much that Chris was almost astonished for a while.After taking a photo of this heartbreaking moment,Chris placed the baby wallaby into the basket of his bike and took it to the local wildlife rescue shelter.The workers told Chris,"It's quite common to find baby wallabies attracted to their dead mothers — often due to the road kill on Magnetic Island. " Hearing this,Chris decided to send the photo to related departments to promote further measures toavoid such things happening again.Rock wallabies have had a tough history in their native country,Australia,as they struggle to fight against extreme weather and keep up with other competitors.The Australian government took a series of protective measures and fought against hunting activities effectively,which made the number of rock wallabies increase.But now,with the development of Magnetic Island,a lot of trucks and private cars flood in,which breaks the previous peace.Experts of the Wildlife Conservation Society（WCS）warn that self-driving travelers and truck drivers should pay attention to the wild animals on the road or by the roadside while driving.4.How does Chris find his trip？______A. It brings him fortune.B. Its influence is worldwide.C. Its result is satisfactory.D. It makes his dream come true.5.What made Chris realize the cause of the mother wallaby's death？______A. The heartbreaking photo.B. The workers' words.C. His travel experience.D. The signs of the scene.6.What may be the best title for the passage？______A. A Beautiful Australian Island Discovered by a Travelling CyclistB. A Heartbreaking Moment Photographed by a Travelling CyclistC. A Wonderful Photography Show Held by a Travelling CyclistD. A Badly Injured Baby Wallaby Saved by a Travelling CyclistCAsk a classroom of children to draw a scientist,and you'll see plenty of colored lab coats and glasses.The image（画像）hasn't changed much since the 1960s,but the person wearing the lab coat is changing.A new analysis finds that more female scientists have appeared in kids？drawings in recent decades — going from nearly nonexistent in the 1960s to about a third in 2016.The first of many "draw-a-scientist" studies asked nearly 5，000 children to draw a scientist between 1966 and 1977.Of those 5，000 drawings,only 28 drew female scientists.That was just 0.56 percent.Today,female scientists are being presented more in the media.For example,in a content analysis,13 percent of people pictured in science feature stories of the 1960s were women or girls,compared with 44 percent in the 2000s. "That might really affect children's idea on what a scientist should be like," says Miller,a Ph.D.candidate in psychology.To look for changes in children's perception over time,the researchers conducted ameta-analysis,combining data from 78 studies that included a total of more than 20，000 children from kindergarten to the 12th grade.On average,28 percent of children drew female scientists in studies conducted from 1965 to 2016.What hasn't changed much：kids pick up stereotypes（模式化观念）by gender（性别）as they grow up.At age 6，about 70 percent of the girls in the more recent studies drew female scientists.By age 16，75 percent drew male scientists.This is an important period in which kids are learning stereotypes.It's important that teachers and parents present diverse examples of both male and female scientists.7.What's the picture of scientists drawn by a 1960s' kid like？______A. A man with long curly hair.B. A woman with lab glasses.C. A woman in a formal lab suit.D. A man in a colored lab coat.8.What may contribute to the changes in kids' drawings？______A. The improvement of women's social status.B. The kids are affected by teachers and parents.C. More female scientists appear in the media.D. The increasing number of female scientists.9.What does the underlined word "perception" in Paragraph 4 most probably mean？______A. Belief.B. Idea.C. Habit.D. Growth.10.It can be inferred from the last paragraph that ______ .A. it's a stereotype that scientists are generally malesB. girls are more influenced by stereotypes than boysC. some children are born with certain stereotypesD. most children tend to prefer female scientistsDRecycling plastic has always been a stop-start effort,and the wide variety of plastics we produce,the pollution from waste,and other limitations make recycling an economic（经济）problem.It's estimated（估计）only 9% of plastic ever created has been recycled.But with the help of a chemical process,Canadian Miranda Wang and her company BioCellection want to change that.Stability is one of plastic greatest qualities and downside.There's limited evidence that some plastics can biodegrade（生物降解）but largely photo-plastics degrade in the sun.It's a longprocess,and the truth is that we can only estimate how long it takes.Wang is looking to break the inaction and BioCellection's task is to make most plastic waste recyclable.She outlines two current methods.One is to take plastics like water bottles,wash them,cut them,melt and reconstitute them. "That's a very limited process" she says,due to the requirement that plastics be "clean".The other,which can handle dirtier plastics and a level of pollution,is called hydrolysis（热解）.Intense heat is applied to break down plastics so they can be reused as oils for energy,but "it's not economical," she says.BioCellection's solution builds on research from over ten years ago,Wang explains,when a US study discovered pure polyethylene powder（聚乙烯粉）could be broken down by a catalyst （催化剂）.Wang and her co-founder Jean hit upon a bacterium being able to eat plastic.In the years since,they engineered a comparable catalyst capable of doing the same job,only faster,which even works on plastics no one else can recycle at present. "We have now found a catalyst that is much cheaper than the one that was used before," Wang says.Currently focusing on plastic films like shopping hags,the three-hour process breaks clown plastic into chemicals that can act as the building blocks for more complex plastic products. "Right now we're able to achieve about 70% transformation from plastic waste material to these chemicals," she adds,saying they're working to increase that figure.11.Why has so little plastic been recycled？______A. Plastic is chemically stable.B. Recycling plastic led to pollution.C. We produced various plastics.D. Most photo-plastics degrade in the sun.12.What does Wang think of the two current methods？______A. Highly effective and dynamic.B. Expensive and pollution-causing.C. Limited and energy-consuming.D. Widely used and recognized.13.What did BioCellection find effective to recycle plastics？______A. Polyethylene powder.B. Chemical products.C. Plastic films.D. A catalyst.14.What is the text mainly about？______A. Miranda Wang and her company.B. A new plastic recycling method.C. The greatest downside of plastic.D. Transformation of plastic waste.二、阅读七选五（本大题共5小题，共10.0分）No matter where you fall on the range of preference for online classes,you can always find ways to do better and improve the way you go about your studies to help you learn the material better.Read on for some tips for acting online classes.Read the syllabus（摘要）The syllabus is supposed to be your guide.

AThe Schoo l’s Community （社区）Service Program encourages all Lawrentians to connect with the greater community, giving them the opportunity to join a variety of people outside the students' present world. Because we want students to have a common service experience that improves their Lawrenceville education and builds community within and beyond the gates, the Community Service graduation requirement is not based on a certainnumber of hours that a student must complete. Instead, students participate in three different types of community engagement (参与).1. Lawrenceville Community Action Project ( LCAP) to be completed in 9th, 10th or 11th grade. LCAPexamples include: a one-term weekly project； being an advisor at Lawrenceville School Camp or Performing Arts Camp ； or participating in a Harkness Travel Program Service Trip.2. Annual participation in the Schoo l’s Martin Luther King All-School Day of Service3. One-time events ( All-School, House, club or team sponsored)——1-3 times before graduationdepending on students, entering year.Students may choose, from over 30 different weekly projects in the Trenton-Princeton- Lawrenceville area.Typically, students do these projects during the evening or on Sunday afternoons if they are playing a school sport, or on a Wednesday or Friday afternoon if they are involved in House or lifetime athletics.Students also sometimes develop their own weekly projects based on their interests and talents. Past projects which were started by students include on-campus (校园)dance, chess and art programs for children.Under the leadership of the Community Service Representative ( CSR) , the Community Service Committee (formed by students who take a leadership role in community service) is responsible for organizing projects and for keeping the Houses informed about community service matters.21. What may an 11th grader do to meet graduation requirement?A. Play football on the city team.B. Work as an advisor at Performing Arts Camp.C. Join in Martin Luther King All-school Day weekly.D.

The Community Service Representative.BA heart-stopping video shows that a group of hikers were able to keep their cool as a curious black bear approached them—and one even stayed composed enough to snap a selfie （自拍）.The black bear pulls one of the women by the leg with its paws（爪子）,moving towards her across the path as she tries to remain completely still. When the frightening animal stands up on its legs to smell her, the fearless walker can be seen taking a photo with the wild animal as it breathes down her neck.The incident is reported to have happened on a path in Chipinque Ecological Park, Mexico, and the clip （剪辑片段）has had millions of views since being shared on social media. With the bear particularly interested in one member of the group, another walker remains frozen with her back to the animal as she stares still into the trees.A third can be seen nervously fearing as the bear begins to approach her and shakes her hand in fear, but it circles back around to check out the first hiker for a second time. It pushes her off balance with its head before twice pawing at her legs as onlookers shout to try and warn the bear off.The woman remains fearless as the animal isn't into her and continues walking up the path, giving the group an opportunity to make a swift exit.It was shared on Twitter by former basketball player Rex Chapman, getting 2.7 million views, with the caption: "Oh, my goodness. She's a rock."24. What does the underlined word "composed” mean in the first paragraph?A. Afraid.B. Confused.C. Disappointed.D. Calm.25. When did the woman take a photo with the bear exactly?A. On seeing the black bear.B. On the bear's pullingher leg.C. On the bear's smelling h erD. On the bear's seeing her.26. Why did the bear leave?A. It was frightened.B. It was hungry.C. It got injured.D. It lost interest.27. From which is the text most probably taken?A. A newspaper.B. A health magazine.C. A research report.D. A brochure.CThey give us paper and fuel, as well as vital ecological set-vices—like cleaning the air, storing carbon and providing home. We're talking about trees, of course.But human changes to the environment appear to be causing great changes to trees around the world. In a new study, scientists reviewed global research on trends in tree seedlings （幼苗），growth, and death. They combined those data with an analysis deforestation （森林采伐）. And they found worldwide, older trees are dying at a higher rate than in the past, due to reasons like rising air temperature, wildfires, drought （干旱）and pathogens （病菌）." And most of the drivers of that decrease in large, old trees are increasing themselves, such as temperature going up, droughts are more severe, wildfires, windstorms, and deforestation are all—although variable across the globe—they're generally increasing. And so both the loss has already occurred, but we expect more continued loss of big, old trees," said Nate McDowell, an earth scientist at Pacific Northwest National Lab, who was one of the study's authors."So if we have an increasing rate of death, particularly of the larger, older trees, what's left are the younger trees. So that's why on average, through the loss of bigger, older trees, our forests are becoming younger and shorter. This trend is a problem, because old trees are vitally important"The increase in death does limit the carbon storage of an ecosystem, and can force the system to become acarbon source to the atmosphere. The second reason is from a biodiversity viewpoint—old trees tend to house a higher biodiversity. And the third reason is linked with beauty: as a society we care about these trees. We have national parks named after these big trees." Nate McDowell added.28. What's the purpose of the author in writing the passage?A. To warn us to care about old trees.B. To call on us to plant more trees.C. To tell us why old trees are dying out.D. To prove forests are becoming smaller.29. Which of the following does Nate McDowell think is a problem?A. There'll be a larger number of older trees.B. Older trees will disappear in the world.C. Young trees will be cut down by people.D. Trees will become younger and shorter.30. Why are old trees important?A. They are beautiful.B. They can shelter a variety of wildlife.C. National parks have access to them.D. They limit the carbon storage of an ecosystem.31. What may be the best title for the text?A. Temperature Destroys Forests.B. Forests Gets Younger and ShorterC. The Reasons of the Loss of Old TreesD. The Dover of the Decrease of Old TreesDAre you the type to run before breakfast in a morning? Working out on an empty stomach won't hurt you ——and it may actually help, depending on your goal.Exercising before eating comes with the risk of feeling light-headed due to low blood sugar. You might feel tired or uneasy, and won't be able to work out as enthusiastically as you would have. A light amount of food is important for older adults over 55 to eat something before exercising — especially in the morning. But if your primary exercise goal is weight loss, exercising on an empty stomach may come with some promising benefits. There's some research to support the idea that working out in a fasted （禁食的）state can burn more fat than exercising in a fed state.Working out on an empty stomach, however, may also not prove true for everyone. u Some people advocate for lasted exercise, but these people tend to be young and in amazing physical - shape," says Douglas Paddon-Jones, a muscle physiology researcher and a professor of aging and health at the University of Texas Medical Branch. "They have no health problems, and what they're eating is super-high quality and carefully regulated. " On the other hand, working out in a fasted state without proper planning or professional oversight may run the risk of unhealthy body composition changes.For people who aren't athletes, fueling up with food before a workout may be the best way to get the most fat-burning benefit. "You don't want to fill up； you just want to give your body a burst of energy to power your training period. After you exercise, drink some water ——but wait 60 to 90 minutes before eating," says Shivani Sahni, director of the nutrition program at Harvard University's Instituted for Aging Research. " You're trying to take advantage of your promoted metabolic （新陈代谢）rate post-exercise, so if you can go an hour or an hour anda half without eating, you'll maximize the fat-burning response," says she.32. Why does the author suggest exercising in a fed state?A. To avoid being light-headed.B. To lower blood sugar.C. To burn more fat.D. To work out energetically.33. Who may tend to practise fasted exercise?A. Older adults.B. Seniors beyond 55.C. Professional athletes.D. Good-shaped athletes.34. What's Shivani Sahni's suggestion for people after exercising?A. Developing a new lifestyle.B. Finding a fitness instructor.C. Going without food for a time.D. Drinking salty water after exercising.,35. Which word best describes the author's attitude to working out in a fasted state?A. Skeptical.B. Cautious.C. Supportive.D. Subjective .第二节（共5小题;每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
