"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 change and 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.4. 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.5. 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.6. What does the underlined word"analogues"in Paragraph 6probably mean?A. Selective things.B. Similar things.C. Variations.D. Limitations.7. What is the purpose of the last paragraph?A. To offer solutions.B. To give examples.C. To make comparisons.D. To present arguments.CA team of researchersfrom theUniversityofColorado Boulderhave created a revolutionary type of robotic muscles. They are strong and flexible at the same time, can feel the movements they perform and, whenever they suffer damage, they can self-heal. However, what is best about them is probably the fact that they are extremely cheap to manufacture.The robotic muscles have been called actuators, and have drawn inspiration from real-life muscles. Bycreating robots equipped with this kind of actuators, researchers would allowthem to perform movements just like human muscles.To make the robotic muscles work, they filled some flexible material with electrodes(电极)and with liquid and oil. Then, they applied some electricity, and the liquid and oil started moving around the electrodes and powered them. This way, the robotic muscles started contracting and relaxing just like real muscles, but a lot quicker.Researchers also took inspiration from the variety of human muscles, and created more types of actuators, each of them performing a different movement. They called these robotic muscles HASEL ( Hydraulically-Amplified Self-healing Electrostatic). However, they are superior to biological muscles as they are stronger, faster, and more flexible.Even the researchers were amazed they could develop such technology. Eric Acome, the author of one of the studies, explained what is unique about the robotic muscles.“The ability to create electrically powered soft actuators that lift a gallon of water at several times per second is something we haven't seen before.”These muscles are special because they are also self-healing. This property is given by the liquid placed inside of them, which also gives them a lot more advantages than those mechanisms (机械)using solids. In the end, the material which keeps the liquid, the oil and the electrodes is extremely cheap. It is a type of polymer (聚合物)similar to the one used for potato chips bags, and can be manufactures for only 10 cents.8. What can we learn about actuators?A. They can heal on their own.B. They are biological muscles.C. They can not move like human muscles.D. They are slower to react than real muscles.9. What do actuators use to directly power electrodes?A. Solids.B. Liquid and oil.C. A type of polymer.D. Potato chips bags.10. What is the last paragraph mainly about?A. The origin of actuators.B. The opinions on actuators.C. The advantages of actuators.D. The significance of actuators.11. In which part of a newspaper will the textmost probably appear?A. Health.B. Culture.C. Education.D. Technology.DA dog spentthe lastfour years of his life waitingat a crossroad in the Thai city ofKhon Kaenas if waiting for someone. People originally thought the dog had been abandoned, but then realized that he looked healthy, so people asked around about him. It turned out that the dog had indeed been spending most of his time around that crossroad, but a woman had been coming round regularly to bring him food and water.One day, while photographing the dog everyone called Leo, a reporter met the woman who had been taking care of him.

2020年郑州市外国语中学高三英语二模试题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AIt was a weeknight and one of my twin daughters marched into the room, waving a book she'd finished. “Dad, why are books with science in them always about boys?” she asked.I told her that simply wasn't true; there were loads of great science fictions with girls in them. She agreed, but argued that in those stories it was the boys who were doing science, and the girls were justalong for the ride. My other daughter took her sister's side and challenged me to give an example.This left me in a difficult position. I could either go through our library to point out some wonderful examples of female-led science fictions, or just admit they were right and remain in my comfortable chair.I've been asked several times how I came up with the idea forA Problematic Paradoxand my answer is always the same: it came to me in a moment of inspiration. I like that answer because it's simple and makes me seem very creative. The fact that this explanation is not true bothers me from time to time. Here's the truth: the story wasn't my idea. It was my daughters who suggested I write something for them that had a girl doing science.My daughters were at an age when many young women turn away from STEM (science, technology, engineering, and math), believing those areas of study unfriendly or out-of-the-norm for girls. I also read about how important role models can be to young people. It's one thing to tell a person they can do something, but seeing someone like them doing that thing can be more powerful.So, I kept two guidelines for the book in mind: First, the story had to be fun for anyone, because it's as important for boys to understand that science is for everyone. Second, I wanted the main character, Nikola, to be imperfect. She should be someone with shortcomings as we all have. I think this not only makes a story more interesting to read, but also helps make it clear that the most extraordinary things can be done by ordinary people.1. What does the underlined phrase “along for the ride” in paragraph 2 probably mean?A. Entering a bike race.B. Offering vital help.C. Doing unimportant things.D. Playing the leading role.2. What do we know about the bookA Problematic Paradox1?A. Its main character is perfect.B. It is a female-led science fiction.C. It is intended to appeal to girls only.D. Its idea comes from the author's inspiration.3. Which of the following best describes the author's book?A. Serious and abstract.B. Simple and practical.C. Creative and well-organized.D. Inspiring and interesting.BSome people take their holiday decoration very seriously. And some take it to the next level. The Griffith family in Kenova, West Virginia, is in this camp. They put on a display that shows they’re just filled with Halloween spirit.Each year, this family displays 3,000 pumpkins (南瓜) in front of their home for the Halloween season. Yes, you readthatright. Ric Griffith puts out one jack-o’ -lantern (南瓜灯) for every person who lives in Kenova.Of course he doesn’t do it all on his own. He has a lot of help from his family, and also from members of the community who are super-proud of what has become quite the tourist attraction over the years. More than 30,000 people stop by to see the amazing display, which includes jack‑o’‑lanterns cut to look like the faces of famous people, animals, cartoon characters, and other creative designs. It’s certainly a must-see as part of the area’s Ceredo-Kenova Autumnfest.To fit in all 3,000 pumpkins, Griffith and his helpers spread them across the home’s garden and front porch (门廊), as well as on the roof!Griffith began the tradition back in 1978 with just fivepumpkins and, many years later, it’s much bigger and better. People can’t help but come to the area, walking along the sidewalk outside the house to get that perfect Halloween experience.“Locals take great pride in it, and then there are people from around the country who plan fall trips and include it in their trips so they can see it,” said Tyson Compton, president of the Cabell‑Huntington Convention and Visitors Bureau. “It’s really something.”“It’s become a tradition for many people in our area, and it feels good to keep that going,” Griffith said.4. What does the underlined word “that” in Paragraph 2 refer to?A. The Griffiths selling 3,000 pumpkins a day.B. Ric Griffith giving 3,000 jack-o’‑lanterns to tourists.C. Ric Griffith teaching 3,000 people how to display jack-o’‑lanterns.D. The Griffiths decorating their house with 3,000 pumpkins.5. What can we learn from Paragraph 3?A. Ric Griffith’s idea has received support from his community.B. There are only two kinds of jack-o’‑lanterns.C. Ric Griffith dislikes asking for help from others.D. There are 30,000 people in Kenova.6. What do we know about the tradition?A. It began with 1,978 pumpkins.B. It has lasted more than 40 years.C. It includes five pumpkin competitions.D. It encourages people to do more exercise.7. What’s Tyson Compton’s attitude towards the tradition?A. Worried.B. Uncaring.C. Favorable.D. Uncertain.CThe outbreak of the novel corona virus pneumonia (NCP) has disrupted the lives and work of nearly every Chinese person. However, a new trend has been on the rise: many have turned themselves into livestreaming users orfollowers.According to Questmobile, a professional big data intelligence services provider in China, the audience for Douyin, Kuaishou and other livestreaming platforms surged to 574 million during the Spring Festival holiday, up 35 percent from 2019.Confined at home, away from their friends and loved ones, people turn to livestreaming to reach out to the world. For them livestreaming can help them share their lives and interest with a global audience, which will give them the sense of being “in the moment”. Even as viewers, they can also engage immediately with livestreamers by commenting and making suggestions.“When I comment on the livestreaming videos, I’m not simply an audience member, but also an active part of the program. That gives me a sense of engagement,” an Internet user named Wang Hao told People’s Daily.Livestreaming is not only for fun, but also a new tool for many businesses. Affected by the pandemic, many businesses had to stop their sales in physical stores. To meet their business goals and survive during these trying times, many chose to livestream to revive their businesses.Joyoung, a leading maker of small kitchen appliances, is a good example. The company not only added a number of broadcasts each day to advertise their products, but also shared the menus that were beneficial to health. “The responses to our livestreaming shows have been well beyond expectations,” Kang Li, who overseesthe company’s livestreaming unit, told China daily. “It’s a natural opportunity to truly bond with our followers.”Like it or not, livestreaming is likely to go mainstream in China for both entertainment and business.8. What is the purpose of writing the second paragraph?A. To introduce some popular livestreaming platforms in China.B. To report data on the development of livestreaming in 2019.C. To show that Chinese people spend too much time on livestreaming apps.D. To prove that livestreaming are becoming increasingly popular in China.9. What does Wang Hao think of commenting on livestreaming?A. It is boring to make comments.B. It is the only way to share viewers’ lives.C. It makes people feel involved in the stream.D. It helps livestreamers improve themselves.10. What do paragraphs 5&6 mainly talk about?A. Livestreaming replaced physical stores in many areas.B. Many businesses turned to livestreaming platform for marketing.C. Livestreaming platforms faced challenges during the pandemic.D. Livestreaming platforms made changes to their services.11. How does the author feel about thefuture of livestreaming？A. Positive.B. Uncertain.C. Disappointed.D. Confused.DIn the Pacific Northwest during winter, 5:15 am might as well be the dead of night. The alarm goes off and the onlylight is the red glow from my clock. My body says, “Go back to bed.” But I don’t. I know my running partner will be waiting in the street and I’m not going to stand her up. Then I walk onto the road, complaining about the cold and wishing I were back under my warm covers.If you’d have asked me a year ago if I could see myself running at 5:15 on a winter morning, I’d have laughed. Morning just wasn’t my thing and running in the morning was something I didn’t even consider. “I prefer to work out in the middle of the morning or in the afternoon,” I’d say to my friends who go to the gym before work.Then, last fall I reconnected with an old neighborhood friend. She’d been running in the morning and taken off forty pounds that year. When I looked in the mirror, I knew I could benefit from the same kind of weight loss. Iasked if I could join her. I knew I needed to change something if I was going to get back in shape.The first two months were especially hard, because we ran twice a week at 5:15 am and I slept till 7:00 the other mornings. But as I’ve adjusted to the routine of running, I’ve discovered great joys that make it even more worthwhile than a little weight loss.While I haven’t lost forty pounds yet, it’s amazing how much more energy I have and how much stronger I feel. Because of the morning run, the rest of my day is more productive. I wouldn’t say I’ve become a morning person, but I would say morning running is now my thing.12. What can we know about the author from paragraph 1?A. 5:15 is the ideal time for her to exercise.B. She prefers to run without any company.C. She takes the run with warm clothes on.D. She goes for a run in spite of the cold and early rise.13. What was the author’s attitude to morning running a year ago?A. Scared.B. Unfavorable.C. Supportive.D. Confused.14. What made the author begin to run in the morning?A. Her partner’s encouragement.B. Her friend’s suggestion.C. Realizing the benefits of running.D. Realizing the harm of being fat.15. What effect does morning runninghave on the author?A. She has become slim again.B. She has become more confident.C. She has become more energetic.D. She has become more exhausted.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。

They found that warmer conditions sped up the sharks’ growing process. That meant the sharks were born earlier and very tired. The findings could be used in the study of other sharks, including those that give birth to live young.The scientists studied 27 sharks. Some were raised in average summer water temperatures, about 27 degrees Celsius. Others were raised in higher temperatures around 29 degrees Celsius and 31 degrees Celsius. They found that the sharks raised in the warmest temperatures weighed much less than those raised in average temperatures. They also showed reduced energy levels.Epaulette sharks can grow to a length of about one meter. Their name comes from large spots on their bodies that look like decorations on some military clothing.One study this year found that worldwide numbers of oceanie sharks and rays dropped more than 70 percent between 1970 and 2018. Overfishing is a main concern, while climate change and pollution also threaten shark.Carolyn Wheeler is a doctoral student at the University of Massachusetts Boston and with the ARC Centre of Excellence for Coral Reef Studies at James Cook University in Australia. She was the lead author of the epaulette shark study. She said that while all the sharks survived, those raised in warmer temperatures were not strong enough to survive for long in the wild.She added that if the sharks are born smaller than usual “they are probably going to have to start looking for food sooner—and they’re going to have less time to adjust to their surroundings.” The study should serve as a warning to ocean governing agencies that careful management is needed to prevent the loss of more sharks.4. In what aspect do the warmer conditions affect the baby sharks?A. Their food.B. Their body weight.C. Their living habits.D. Their moving route.5. How did the scientists carry out their study?A. By studying former data.B. By tracking sharks in the wild.C. By collecting information about climate change.D. By comparing sharks in waters of different temperatures6. What does paragraph 5 mainly talk about?A. The origin of sharks’ names.B. The sharks’ appearance.C. The threats to sharks’ survival.D. The sharks’ living environment.7. Which of the following can be the best title for the text?A. Scientists Raise Sharks to Deal with ProblemsB. Global Warming Has Reduced Shark PopulationsC. Baby Sharks Struggle to Survive in Warming OceansD. Scientists Are Struggling to Save Sharks from ExtinctionCResearchers say spicy tomatoes could soon be on the menu thanks to the rise of gene-editing technology.It's not the first time that experts have claimed techniques could develop fruit with unusual features: scientists have already been looking at changing the color1 of kiwi fruit and bettering the taste of strawberries.But researchers inBrazilandIrelandsay such methods could also offer practical advantages, with hot tomatoes offering a new way of harvesting the pungent chemicals found in peppers known as capsaicinoids, which make food taste “hot”.“Capsaicinoids are valuable. They are used as painkillers and there are some researches showing that they promote weight loss,” said Agustin Zsogon from a Brazilian university, a co-author of a new article arguing for the benefits of engineering hot tomatoes.Writing in the journal Trends in Plant Science, the researchers say peppers are difficult crops to grow and low productive. Worse still, it is tricky to keep the pungency of the fruits table. By contrast, tomato production is high and the plant is well-studied. “You could produce the capsaicinoids in a more cost-effective manner,” said Zsogon.Tomatoes and peppers developed from a common ancestor, but separated about 19 million years ago. “All these genes to produce capsaicinoids exist in the tomato, they are just not active,” said Zsogon. “Using gene-editing technology, it is likely to switch these genes back on in tomatoes, making the fruit more special”, he said.8. Why are the tomatoes made hot by the researchers?A. To test the gene-editing technologyB. To improve the amount of the tomatoesC. To explore ways to harvest more capsaicinoids.D. To make the tomatoes more delicious.9. For what purpose can capsaicinoids be used according to the text?A. To put on weight.B. To ease the pain.C. To improve sleep.D. To better the look.10. What is Zsogon's attitude to the gene-editing technology?A. Confident.B. Critical.C. Anxious.D. Doubtful.11. What's the main idea of the text?A. An introduction to gene-editing plants.B. Creating hot tomatoes by gene-editing.C. Problems with capsaicinoid production.D. The procedure of producing capsaicinoids.DFor decades, an organization, called Ulum Dalska, based in a small Swedish town called Alvdalen, hasbeen working hard to help save a language called EIfdalian. Elfdalian sounds nothing like the country's national language, Swedish, which press secretary Bjorm Rehnstrom said affected the language about 100 years ago. At that point, Elfdalian declined. Ulla Schitt, also a Ulum Dalska member, experienced the change while growing up in Alvdalen.“My parents spoke Efdalian with each other, and with my grandma and my aunts and uncles and everyone around,”Schit said. “But when they turned to me, they spoke Swedish.” Schitt said her parents spoke Swedish with her because that's what was spoken in schools.But people are getting creative in the fight to change that trend. Musicians are creating new songs with Elfdalian. Several children's books were also translated into EIfdalian, including Le Petit Prince by Antoine de Saint-Exupery. Additionally, Bjorm Rehnstrom helps run a popular Facebook group that offers courses in the Elfdalian language, where he offers lessons to the group's 1,800 global members from America, Australia, South America, Indonesia, Haiti and Cape Verde.The local government supports the teaching and preservation of Elfdalian. Bjom Rehnstrom said they eagerly paid for a sign that reads: “Welcome to Alvdalen” in Elfdalian. But the national government of Sweden is a different story. They currently consider Eidalian a dialect of Swedish, not its own language.Schitt said every time a language dies it is a sad moment.

It’s the kind of nervousness that makes you bite your nails before a big test. We spend more time online than we should. We feel good about ourselves or bad based on how many Likes and Followers we get on social media. Young people are developing a false view of life.On the screen, we see what people want to show us. People usually only post photos where they are looking their best. They are surrounded by friends and seem that they are having a great time. No one seems sad or lonely. In short, life isfabulous. But sooner or later, our young people compare their real life to it. They find that theirs doesn’t seem as fun or exciting and grow worried that they may be missing out.No wonder teachers are reporting more anxious students. It’s reported that a lot more college students feel ―overwhelming anxiety. The percentage jumped from 50% in 2011 to 62% in 2016. Anxiety is now the most common mental-health problem in my country. It affects nearly one-third of teens and adults.Certainly, we can’t blame it on social media alone. We expect toomuch from our children and a lot of these expectations aren’t reasonable. Their schedules are packed with sports, clubs and homework. They don’t have enough free time. We want our children to succeed, and we don’t care how much it costs.As parents, we must have more balance. On one hand, we push too hard, and on the other hand, we make life too easy for children.

There is another way to help your friends or other people to find you. You can shout or whistle three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help.Keep up shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you two shouts or two whistles. When a signal is given twice, it is an answer to a call for help.If you don’t think that you will get help before night comes, try to make a little house with branches(树枝). Make yourself a bed with leaves and grass.When you need some water, you have to leave your little branch house to look for it. Don’t just walk away.

It was the largest wildfire in the state's recorded history, breaking the record previously set in 2018. After the fire, land managers must determine where to most efficiently plant new trees.A predictive mapping model called the Postfire Spatial Conifer Restoration Planning Tool recently described in Ecological Applications could inform these decisions, saving time and expense. The tool can “show where young trees are needed most, where the forest isn't going to come back on its own, where we need to intervene（干预）if we want to maintain forests," says lead author Joseph Stewart, an ecologist at the University of California, Davis.To develop the model, Stewart and his colleagues classified data collected from more than 1,200 study plots in 19 areas that burned between 2004 and 2012. They combined these data with information on rainfall, geography, climate, forest composition and bum severity.Theyalso included how many seeds sample conifer trees （针叶树）produced in 216locations over 18 years, assessing whether the trees release different numbers of seeds after a fire.The tool's potential benefits are significant, says Kimberley Davis, a conservation scientist at theUniversityofMontana, who was not involved in the study. Those managers will still have to make hard decisions, such as which species to plant in areas that may experience warmer and drier conditions resulting from climate change, but the model provides some research-based guidance to help the forests recover.12. What challenge do land managers face after the wildfire?A. Lack of wood supplies.B. Where to plant new trees best.C. How to save the burned trees.D. Loss of trees and wild animals.13. What's the main idea of paragraph 2?A. The function of the tool.B. The disadvantages of the tool.C. The improvement of the tool.D. The development of the tool.14. What does the underlined word "They" refer to?A. The study plots.B. The data.C. Stewart and his colleagues.D. The seeds.15. What isDavis' attitude towards the tool?A. Skeptical.B. Ambiguous.C. Tolerant.D. Optimistic.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。

2020届郑州外国语学校高三英语二模试卷及答案第一部分阅读（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ABest Places to Visit in JulyNorway's FjordsMost travelers prefer to visit Norway's famous fjords (峡湾) in July because Norway has about 23 hours of daylight, giving travelers lots of time to take in the spectacular views of blue water, glaciers and mountains. July is also whenNorway's weather is at its warmest, about18℃, so travelers might include a light sweater in their luggage.Bastille Day inParisJuly 14 is a national day celebrating independence to the French. July 14, 1789, is the day the French stormed the Bastille, aParisprison, and officially began the French Revolution, overthrowing a royal government that often threw people in prison there for no reason at all. While the day is marked all overFrance, the biggest celebration takes place inParis.Masai Mara National ReserveThe thrill of seeing millions of animals wander the plains inKenyais not easily forgotten. One of the most popular months to visit the Masai Mara is in July when the famous wildlife migration reaches the Masai Mara and zebras are at their highest number. The best times to view the animals inKenya's most popular game park are dawn and dusk.Running of the Bulls inPamplonaTravelers who pride themselves on being fast runners may want to head toPamplonain July for the San Femin Festival. A key part of this annual festival is the running of the bulls.

Masai Mara.D.Pamplona.BThe Rise of Voice TechnologyVoice technology has come a long way. Just a few years ago, it would have been unusable. But now, those who follow the technology know that it has got considerably better.Writing with your voice raises several interesting questions. How difficult is it actually? Human speech involves a lot more starting and stopping with errors and the need for repairing broken sentences than you may think. Even gifted speakers make mistakes. To turn the spoken word into reasonable writing requires lots of planning. You’ll need some kinds of notes or other organisers to make it work.Another question turning speech into writing raises is the style. How would writing make the change that people speak their writing rather than type? Chances are that it would come up with many more short sentences and more concrete language, which is good. It would probably also rely on prepared phrases a lot more often, which is not available when you are speaking quickly.To confirm this, a column was not written, but dictated (听写). It was composed from brief notes written down for structure only, and it was edited for length, with all of the original errors kept in. Here were the results. The first was that the literal accuracy was extremely high. There weren’t many cases wherethe software had heard one word incorrectly and written down another. But the other result was that the readability of this column was rather bad. Obviously, the blame is not with the technology at all, which turns out to be rather good. Speaking into writing relies on a better human brain than the one we currently possess. Writing is hard. There’s a reason it can’t be done at the speed of speech, in real time.To clarify the matter, this time paragraph breaks were added after the whole writing. Punctuations (标点) had to be spoken aloud, and after a full stop, the first word in the new sentence was capitalized automatically. Some minor punctuation marks were added to make it clearer. To improve accuracy, people “trained” the software beforehand, reading a prewritten passage aloud. Actually it turns out to be more effective. All of these ensure the satisfactory completion of turning speech into writing.Language is the most important tool for human interaction, and voice is one beautiful part of language. With the maturity of modern technology, it has given birth to a great change in the human-computer voice interaction.4. According to the passage, which helps to turn speech into writing in terms of style?A. There is careful planning in advance.B. Errors and broken sentences are avoided.C. People type words as fast as they say them.D. The writing contains more prepared phrases.5. To achieve better results, the author mentions some changes for ______.A. processing errors in a column.B. adding minor punctuation marks.C. increasing the number of brief notes.D. integrating short paragraphs in writing.6. The author suggests that ______.A. human brains are responsible for poor dictated writing.B. writing with voice promises to improve the quality of writing.C. writing is an unnatural act that can hardly be learned and improved.D. technology has a long way to go in the human-computer voice interaction.7. What is the passage mainly about?A. Why people fully intend to turn speech into writing.B. What role voice technology plays in improving readability.C. Where the human-computer voice interaction is at an advantage.D. How voice technology enables the change from speech into writing.C“One person’s trash is another person’s treasure.” That’s a common expression, but the next time you throw something away, think about a twist on the old saying. What if your trash could become your own treasure? Many creative, thrifty, and environmentally minded people have come up with a way to makethathappen. It’s called upcycling. Our world would be a better place if everyone would begin upcycling.Upcycling is the practice of taking an unwanted item and turning it into something useful. For example, how about that pair of jeans with a hole in one knee? It could become a new pillow for your bedroom.Upcycling is not the same as recycling. Upcycling is actually much better for the environment. Recycling takes an item made of glass, paper, metal, or plastic, breaks it down to its base material, and then uses that material to make another product. This requires a great deal of energy. On the other hand, when you choose to upcycle, theonly energy you use is your own. And upcycling not only reduces the amount of trash that goes into our landfills, but it also protects natural resources, such as oil and gas. Recycling is good for the environment, but upcycling is even better.Upcycling also makes a family’s budget stretch further. Of course, the idea of reusing items to save money is not new. During the Great Depression in the 1930s, many families lived on a tight budget. People had to use what they already had in order to meet their needs.As responsible citizens, we should all be concerned with protecting our environment and budgeting our resources. Upcycling is a fun and creative way to help. The next time you go to toss something into the trash can, stop and think about what it could become. Chances are, there’s a brand-new item in your hand just waiting to be upcycled.8. Why does the author mention an old saying in the first paragraph?A. To arise reader’s awareness of upcycling.B. To stress the importance of upcycling.C. To lead in the topic of upcycling.D. To show the idea of upcycling.9. Which one below belongs to upcycling?A. An old ladder is transformed into a bookshelf.B. Old tin cans are transported to landfill.C. A broken wooden door is chopped up.D. Old cloth is made into a paper bed.10. What is the difference between recycling and upcycling?A. Upcycling is much more creative.B. Recycling is much easier to achieve.C. Recycling is much more cost-saving.D. Upcycling is much more energy-efficient.11. What can be inferred from the text?A. Upcycling is popular at present.B. Upcycling is replacing recycling.C. Upcycling is worth recommending.D. Upcycling is a tradition in daily life.DCraig Blackburn, a father and car fan, built a Batmobile for his son’s hope for using the vehicle to brighten the lives of sick children.

It was so good to see the kids’ and adults’ excitement at seeing the Batmobile.” Mr. Blackburn said. As a result, the car lovers hope to make the car work on the roads as soon as possible, so he can visit sick children and take them out with his son.12. What is Craig Blackburn’s initial purpose of making the Batmobile?A. To realize his son’s dream.B. To donate it to sick children.C. To pay his respects to the film Dark Knight.D.

2020届郑州实验外国语中学高三英语二模试题及答案第一部分阅读（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AIn his 402nd anniversary year, Shakespeare is still rightly celebrated as a great language master and writer. But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BOnce a rich and clever boy had practically everything a boy could want, so he was not interested in most toys. But he couldn't get a very old mirror, and heconvinced his parents to buy it from mysterious（神秘的）old man. When the mirror arrived home, the boy went to see his reflection in it. His face looked very sad indeed. He tried smiling and making funny faces, but his reflection continued with its sad expression. "What a terrible mirror! It's the first time I've seen a mirror that didn't work properly!" the boy jumped violently.That same afternoon he went into the street to play and bought a few toys, but on his way to the park he saw a little girl who was crying her heart out. The girl was crying so much and looked so lonely that the rich boy went over to help her and to see what had happened. The little girl told him that she had lost her parents.Together the two set off in search of the parents. As the little girl wouldn't stop crying, the boy spent his money buying her sweets to cheer her up. Finally, after much walking, they found her parents who were much worried and were looking for her everywhere.The rich boy said goodbye to them. As it was getting late, he decided to head for home, without being able to play. At home, he went to his room, and noticed a shining light in the corner, the same corner he had left the mirror in. Seeing this, he went over to the mirror, and realised that the light was coming from his own body, so radiant（闪亮的）with happiness he had become.And so he understood the mystery of that mirror, the only mirror which could faithfully reflect the true joy of its owner. He realised it was true. He felt very happy at having helped that little girl. And since then, each morning when he looked in that mirror and failed to see a special shine, he knew what he had to do to bring it back.4. How did the boy feel when he first looked into the mirror?A. Embarrassed.B. Angry.C. Worried.D. Delighted.5. Why was the little girl crying so hard?A. She couldn't find her parents.B.

I remember one night after a long, hard day at work, my mom placed a plate of eggs, sausage, and a plate of extremely burnt biscuits on the table. I waited to see if my dad would get annoyed.All my dad did was to reach for the biscuits, smile at my mom and ask me how my day at school had been. I don't remember what I told him that night but I do remember watching him add butter and jelly on that ugly burnt biscuit and ate every bite of that thing. He never made a face nor uttered a word about it!When I rose from the table that evening, I remember hearing my mom apologize to my dad for overcooking the biscuits and I will never forget what he said, “Honey, I love burnt biscuits every now and then."Later that night, I went to say good night to my daddy, and I wondered if he really liked his biscuits burnt. He wrapped me up in his arms and said gently, "Your mom put in a hard day at work today and she is really tired. Besides, a little burnt biscuit never hurt anyone!As I have grown older, I've thought about that many times. Life is full of imperfect things and imperfect people. Learning to accept each other's faults and choosing to celebrate each other's differences contribute to a healthy, growing, and lasting relationship. We could extend this philosophy to any relationship, such as a husband-wife, parent-child, or friendship. Don't put the key to your happiness in someone else's pocket. Keep it in your own. So, please pass me a biscuit, and yes, the burnt one will do just fine.8. How did the author's dad react to the burnt biscuit?A. He set it aside for breakfast.B. He ate butter and jelly instead.C. He uttered his complaints loudly.D. He ate it up as if nothing happened.9. Which of the following words can best describe the author's dad?A. Caring.B. Determined.C. ProudD. Hardworking.10. What does the author suggest people do in the last paragraph?A. Show understanding to imperfect things.B. Ask the children to respect their parents.C. Enjoy the over-cooked biscuits willingly.D. Make important decisions on your own.11. In which section of a magazine may this passage appear?A. History and culture.B. Family and relationship.C. Cuisine and health.D. Entertainment and sports.DImust have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don’t remember mom reading me a storybook by my bedside. I was extremely inspired by the wonderful way the words sounded.I always wanted to know what my mom was reading. Hearing mom say, “I can’t believe what’s printed in the newspaper this morning,” made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, “The C-A-N-D-Y is hidden on the top shelf,” I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A’s on my tests. Sometimes, I would read a novel that was assigned, but I didn’t enjoy this type of reading.I liked facts, things that are concrete. I thought anything abstract left too much room for argument.Now that I’m growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don’t have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.We’re taught to read because it’s necessary for much of human understanding. Reading is an important partof my life. Reading satisfies my desire to keep learning. And I’ve found that the possibilities that lie within books are limitless.12. Why did the author want to grab the newspaper out of mom’s hands？A. She wanted mom to read the news to her.B. She couldn’t wait to tear the newspaper apart.C. She couldn’t help but stopmom from reading.D. She was eager to know what had happened.13. According to Paragraph 3, the author’s reading of road signs shows___________.A. her own way to find herselfB. her eagerness to develop her reading abilityC. her growing desire to know the world around herD. her effort to remind mom to obey traffic rules14. The author takes novel reading as a way to___________.A. explore a mysterious landB. develop an interest in learningC. get away from a confusing worldD. learn about the adult world15. What could be the best title for the passage？A The Pleasure of Reading B. Growing Up with ReadingC. The Magic of ReadingD. Reading Makes a Full Man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。

I quickly became depressed and angry at myself for not being about to do better in school, in addition to lack of friends due to poor social and communication skills.This went on for months until my 19th birthday. My parents sent me a cake, which was a great cake. But I remember having this large cake and ly no one to share it with. I ended throwing out the cake after having one piece, with about 90 % of it leftover. That night I was depressed that I decided to go outside to the freezing temperature of the winter and run. I put my earphones in, went outside and ran about 2 miles at 11 p.m. on my birthday.When I got back inside I was content. I was proud of what I was able to do. The next night I did the same. I wasn’t quick or fit but you know that I went outside and did something. This continued for about 2 months until I finally worked up the courage to go to the gym, where I started swimming again as I used to in high school. A month went by and I started lifting weights and continually running.Looking back I can see that exercise helped cure my depression but it didn’t only do that. At the gym I met new friends and back at my dorm I grew confidence to go to the end of the hall seeing people playing SuperSmash Brothers and ask if I could join.So go forward to present now. I exercise every day and look forward to that hour and a half I get daily to do what I love with people who love it as well. I hope this helps someone who may be or have been in a similar situation.4. What made the author decide to run at night?A. His l9th birthday.B. His parents’ cake.C. His loneliness.D. His friends.5.

One day, he played with his brother along the rail line and fell asleep. When he woke up, he found himself alone. So he got on the train in front of him to search for his brother.That train took him a thousand miles across the country to a totally strange city. He lived on the streets, and then in an orphanage (孤儿院), where he was adopted by an Australian family and taken to Tasmania.Brierley is a famous writer now, and in his new book,A Long Way Home, he wrote he couldn’t help but wonder about his hometown back inIndia. He remembered landmarks, but since he didn’t know his town’s name, finding a small neighborhood in a vast country seemed impossible.Then he found a digital mapping program. He spent years searching for his hometown in the program’s satellite pictures. In 2011, he came across something familiar. He studied it and realized he was looking at a town’s central business district from a bird’s-eye view. He thought, “On the right-hand side you should see thethree-platform train station”—and there it was. “And on the left-hand side you should see a big fountain”—and there it was. Everything matched!Standing in front of the house where he grew up as a child, he saw a lady standing at the entrance. It took him a few seconds but he finally remembered what she used to look like.In an interview Brierley says, “My mother came forth and walked forward, and I walked forward, my eyes filled with tears and my brain blank. I just didn’t know what to say, because I never thought seeing my mother would ever come true. And here I am, standing in front of her.”8. Why did Brierley get on the train when he was a little boy?A. To go back to his home.B. To look for his brother.C. To travel toTasmania.D. To follow a stranger.9. What made it difficult for Brierley to find his hometown?A. The vast area ofIndia.B. The fact that he was nobody then.C. His not remembering the town’s name.D. The distance betweenAustraliaand his hometown.10. How did Brierley find his hometown?A. By studying digital maps.B. By analyzing old pictures.C. By travelling all aroundIndia.D. By spreading his story via his book.11. What’s the best title of the passage?A. Love for MotherB. Union with BrotherC. Memory of HometownD. Long Way back HomeDThe race skywards began inAmerica. In the late1800s, industrialization had driven urban populations and land prices up, making tall buildings increasingly cost-effective, according to Carol Willis, director oftheSkyscraperMuseuminNew York, “The very first tall buildings were office buildings that concentrated a work force, piled one on top of the other in order to make business very efficient, ”she says.Like all major changes in architecture, the trend wasunderpinnedby engineering. The development of steel framework, which could be used instead of load-bearing stones, made it easier and cheaper to build tall. The coming of the elevator, meanwhile, made living on higher floors far more convenient.Though similar in shape, today's skyscrapers (摩天大楼) look little like those built in the first half of the 20thcentury. This is mostly thanks to architecture's next major technological shift：the curtain wall.Postwar developments in manufacturing meant that huge panes of glass could be produced quickly and uniformly, and glass windows soon became the front of choice for high-rises. As well as allowing for greater floor space and more natural light, glass exteriors (外部) help. buildings resist greater windloads.There are now 191 completed skyscrapers that are at least 300 meters tall. But that doesn't mean our cities will grow taller indefinitely. While each additional story adds sellable floor space, construction costs also rise. All buildings reach a point where adding an extra floor will cost more money than it brings.“Every city wants to have this landmark that gives that sense of distinct culture, ”but it also needs places for people to live and work in urban settings“without the city sprawling (无序扩张), ”explains Hong Kong architect Simon Chan.The next big challenge facing architects goes beyond height：At a time when buildings and their construction account for more than a third of the world's energy consumption and contribute about 40% of greenhouse gas emissions(排放), there are new costs to consider.Whether it's employing more energy-efficient materials, encouraging natural air or using buildings themselves to generate solar or wind energy, reducing carbon emissions is the new frontier for many skyscraper architects.12. What does the underlined word“underpinned” in paragraph 2 probably mean?A. Created.B. Prepared.C. Suggested.D. Supported.13. What made living on higher floors much more convenient?A. The development of steel framework.B. Load-bearing stones.C. The use of the elevator.D. The curtain wall.14. What can we know from paragraph 5?A. Our cities will grow taller definitely.B. All skyscrapers are at least 300 meters tall.C. Construction cost rises as the stories increase.D. The profit for builders will be greater as the building becomes higher.15. What's the next big challenge facing architects?A. How to build the greenest building.B. How to build the strongest building.C. How to build the tallest building in the world.D. How to build the most comfortable building.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。

Touching our faces—the "T-zone" of our eyes, nose and mouth in particular—can mean giving ourselves the deadly virus.This is why organizations like the Centers for Disease Control and Prevention (CDC) have suggested that we avoid touching our faces. "Just stop this simple behavior," William Sawyer, founder of Henry the Hand, a nonprofit organization that promotes hand hygiene (卫生), told The Washington Post. "It's the one behavior that would be better than any vaccine (疫苗) ever created."Yet, stopping this "simple" behavior might be harder than you think because it's already hardwired (固定存在于) into our system.Some face touchingis an automatic reflex (反射) —like when there is an itch (痒) on your nose, you'll scratch (挠) it without thinking. According to CNBC, a 2014 study found that touching your face also helps to reduce stress and regulate emotions. For example, you're more likely to do it when you feel awkward or embarrassed. According to Dacher Keltner, a psychologist at the University of California Berkeley, US, this action may also come with a social function: When you are talking to someone and want to change the subject, for example, touching your face is like "the curtains on a stage, closing up one act of the social drama, ushering (引导) in the next," Keltner told the BBC.Moreover, face-touching in almost all of these occasions is subconscious, which means it's very hard to change "because you don't even know you're doing it", said Sawyer. But you're not alone. In a 2015 study, wherea group of medical students were filmed in class, it was found that they touched their faces an average of 23 timesan hour—with 44 percent of the touches being in the "T-zones". That was particularly surprising since medical students were supposed to know better.Since it's so hard to shake the habit, maybe the easiest way is to wash our hands more often. This way, we can be sure that our hands are free from the novel coronavirus.4. What do the first two paragraphs talk about?A. The best way to fight COVID-19B. How organizations are fighting COVID-19.C. Typical hand hygiene problems in the fight against COVID-19.D. The necessity to avoid touching our faces to fight COVID-19.5. Why is it hard for people to stop touching their faces?A. It makes people feel more confident.B. Many are unaware of this behavior's risks.C. They usually do it automatically and subconsciouslyD. Many think the action helps them express their emotions.6. Which of the following is a social function of touching faces, according to the text?A. Using it as a sign to change the topicB. Bringing a conversation to an end.C. Showing an interest in the ongoing subject.D. Making others feel relaxed while talking.7. What is the author's purpose in mentioning a 2015 study on a group of medical students?A. To give tips on how to stop touching faces.B. To prove that it is common for people to touch their faces.C. To show it is impossible to shake the habit of touching your face.D. To show how hygiene awareness helps people avoid touching their faces.CHave you ever done something for someone else—knowing that your actions would solely benefit THEM and not YOU? Maybe you opened a door or donated blood or volunteered in a hospital’s ER during the pandemic. This is called a prosocial behavior. Humans engage in these types of behaviors all the time.But a question remains in science: Are we the only species who do this? As one of out closest s, chimpanzees have long been studied for signs of this. So far, research has provided mixed results on the question.Some studies show that chimps cooperatively hunt, share food and comfort each other. But one study came to a very different conclusion. The study used a controlled lab experiment where chimpanzees in enclosures were given two options: push a button to give food to themselves or push the button to give food to themselves AND a partner chimp. If they chose the latter, it was seen as a prosocial behavior. But the result is that chimps showed no special preferences for feeding themselves and a friend over feeding just themselves. Another study conducted by DeTroy, however, discovered a totally different result.Compared to previous controlled lab-based experiments, the setup for DeTroy’s research was very naturalistic. “We installed a button and a fountain into the chimpanzees’ outer enclosures. When an individual pushes the button, it releases juice from the fountain. However, since the button and fountain are approximately five meters apart, the individual pushing cannot directly drink from the fountain. And if any other chimpanzees are at the fountain when the button is pushed, they, and not the pusher, will be able to drink the juice.In this experiment, chimpanzees showed a willingness to act in the interest of others, with individual chimpanzees prepared to push the button without benefiting themselves.“It is really fascinating to see that many of the chimpanzees were willing to prosocially provide valuable resources to the group members even if they couldn’t benefit themselves from their behavior.” said DeTroy.Further research may reveal what lies behind their prosocial motivation. But for now, it’s safe to assume that chimpanzees are not simply aping human behavior.8. Which of the following belongs to prosocial behaviors?A. Jack participated in voluntary work in the library just to earn credits.B. Mark turned to his classmate for help when feeling stressful in study.C. Tim guided a lost child back home on his way to an important job interview.D. Rose often interrupted the teacher to ask questions actively in the math’s class.9. What is the task of the chimpanzees in the lab-based study?A. Sharing food.B. Making a choice.C. Comforting others.D. Showing sympathy.10. How is DeTroy’s study different from the previous ones?A. It was based on controlled lab experiment.B. It gave juice to the chimpanzees as a reward.C. It offered the tested chimpanzees a natural surrounding.D. It provided a chance for chimpanzees to help their partners.11. What can we learn from DeTroy’s quotes?A. Chimpanzees can develop abilities to help others.B. Chimpanzees have acquired many human behaviors.C. Chimpanzees in the wild is cleverer than those in the lab.D. Chimpanzees displayed prosocial behaviors for certain rewards.DIt was five years ago that something unforgettable happened. My wife and I celebrated our 40thwedding anniversary that year. It was a lovely event hosted by our sons for us. My wonderful friends from the past surprised us with gifts and congratulations. Our gift to each other was a driving trip out west. We drove fromOntariointoAlberta, then southward intoGlacierNational ParkinMontana, and continued toYellowstoneNational Park.It was a cold spring day, and theBeartooth Highwayhad opened for the season just days before. Alongside the road, there was still a great amount of snow there. The scenery was so impressive that we made lots of stops to record memories with my camera. At the highest point of the highway, I stopped at a lookout to catch the amazing views, with my wife in the centre of my camera lens.There were not many cars on the road. Sometimes, cars with energetic young tourists passed by. And then we heard a motorcycle in the distance. The driver of the motorcycle, who wore dirty clothes, parked behind our cars. As he approached us, his only words were, “Give me your camera and get over there with your wife.” I must admit I felt nervous that we might be robbed where we just created some beautiful memories. Surprisingly, he just took a picture of us, handed back my camera and rode off before we could express our gratitude. The photo he took is one of the most valuable and prized of our trip.I learned my lesson somewhere I least expected it. We should never judge a man by his appearance. If the motorcycle driver reads this story and remembers the situation, we would like to say “Thank you” to him.12. According to the passage, what do we know about the trip?A. It was taken by train to the west.B. It was a suggestion from their friends.C. It was in the late autumn five years ago.D. It was a gift for their wedding anniversary.13. Why was the author nervous when the motorcycle driver offered to take a picture?A. He could have lost the camera.B. His wife might not be satisfied with the view there.C. The motorcycle driver would borrow the camera.D. The motorcycle driver might not be good at the taking pictures.14. Which of the following best describes the driver of the motorcycle?A. Kind and straightforward.B. Rich and generous.C. Creative and capable.D. Careful and admirable.15. Which of the following can be concluded from the passage?A. No pains, no gains.B.

Crowds celebrate with viewing parties,flockingto the most popular locations to take photos and have picnics underneath the branches.But this year, cherry blossom season has come and gone in the blink of an eye, in one of the earliest blooms on record. Scientists warn it’s a symptom of the larger climate crisis threatening ecosystems everywhere.Yasuyuki Aono, a researcher atOsakaPrefectureUniversity, has gathered records fromKyotoback to 812 AD from historical documents and diaries. In the central city ofKyoto, cherry blossoms peaked on March 26, the earliest in more than 1,200 years, Aono said. And in the capitalTokyo, cherry blossoms reached full bloom on March 22, the second-earliest date on record.The peak bloom dates shift every year, depending on numerous factors including weather and rainfall, but have shown a general trend of moving earlier and earlier. InKyoto, the peak date stayed around mid-April for centuries, but began moving into early April during the 1800s. The date has only dipped into late March a handful of times in recorded history.“Sakura blooms are very temperature sensitive,” said Aono. “Flowering and full bloom could be earlier or later depending on the temperature alone,” he said. “The temperature was low in the 1820s, but it has risen by about 3.5 degrees Celsius to this day.”This year’s seasons in particular influenced the blossom dates, he added. The winter was very cold, but the spring came fast and unusually warm.4. What is the best title of the passage?A. Cherry blossom celebrations.B. Warning of a climate crisis.C. A strong love for cherry blossom.D. Cherry blossom season coming earlier.5. What does the underlined word “flocking” mean?A. Blocking.B. Flooding.C. Running.D. Following.6.

To make people aware of the influence of climate change on cherry blossom.CKids often admire well-known celebrities, putting posters of their favorite musicians, movie stars and athletes on their bedroom walls. But rarely does a young person get to meet or talk to their idol. Yet for one young tennis player - Coco Gauff - her chance to do just that happened in an amazing way!Coco was born on March 13, 2004. At the age of 4, she developed an interest in tennis after watching Venus Williams win the Australian Open on TV. Coco began playing at 7 and showed a real talent for the sport. When young Coco turned 10, she began training at a tennis centre run by Venus's coach, Patrick Mouratoglou. He still remembers the first time he met Coco. He says, “She impressed me with her determination and fighting spirit. ” Convinced of her talent, Mouratoglou sponsored（资助）Coco to attend his academy in France. While she was preparing to go to the academy in 2019, she received a call that would change her plans and her life!Wimbledon（温布尔顿网球比赛）organizers called and offered Gauff entry to the tournament（联赛）as a wildcard（外卡选手）.This madeher one of the youngest players to ever qualify.

The Significance of Admiring an Idol.DWhether for a special holiday, as a way of showing gratitude or just a way of letting someone know you care, gift giving is a universal custom Though the purpose may be similar from place to place, traditions vary widely from one country to the next. A behavior that shows respect in one place might be consideredoffensivesomewhere else. Take a look at unique gifting traditions from around the world.Here in theUS, a set of kitchen knives seems like the perfect gift idea for a wedding. However, in certain European countries likeGermany, people believe that a knife presented as a gift will cut off your friendship. There is a way to break it: Tie a coin to the knife or gift box. The receiver then returns the coin to you as a “payment”to remove the bad luck.There's a well-known Italian wedding tradition where the groom's (新郎) tie is cut into a number of tiny pieces. Wedding guests can then "buy” these tie pieces in exchange for cash. It's a fun way to give money to the new couple thatleaves guests with a wedding souvenir.As left hands are considered unclean in Indian culture, behaviors such as touching, passing money, or giving gifts are to be done with the right hand. Different from some other cultures , an odd number (奇数) of thingsor currency represents good luck. For example, £11 should be given rather than £10.InZimbabwe, it is common to directly ask for a gift. When you receive a gift without asking for it, even if the giver's family is poor, it's the worst way to reject the offering. Also, expressing thanks with actions is better than giving thanks orally (口头地).These may include jumping up and down, dancing, or whistling.12. What does the underlined word “offensive“ in paragraph 1 refer to?A. Rude.B. Creative.C. Suitable.D. Caring.13. How do people prevent friendship breaking down when giving gifts like knives?A. The guests cut the groom's tie into pieces.B. The receiver returns the coin to the giver.C. The giver gives gifts with the right hand.D. The receiver expresses thanks by dancing.14. What can we learn about the gift giving inZimbabwe?A. It is not proper to ask for a gift directly.B. It's better to reject a gift from a poor family.C. One can express thanks by writing letters.D. Showing gratitude with actions is better than words.15. Which can be a suitable title for the text?A. The Wayof Showing GratitudeB. A Fun Behavior to Respect PeopleC. Various Gift Giving TraditionsD.

2019-2020学年郑州实验外国语中学高三英语二模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AFor some people, there’s no better companion than mans best friend-a dog. This four-legged pet can bring comfort and joy and provide much- needed exercise for you when it needs walkies! This probably explains why dog ownership increased last year because people spent more time at home during he CovID-I9 lockdown.However, as demand for a new dog increased, so did the price tag. Popular breeds, such as Cockapoos and Cocker Spaniels, saw even sharper price increases, and puppies have been selling for $3,000 or more.Animal welfare charities fearthat high prices could encourage puppy farming, smuggling (走私) or dog theft. An investigation found some breeders have been selling puppies and kittens on social media sites--something charities have called “extremely irresponsible”.But despite some new owners purchasing a dog legally, maybe from a rescue center or registered breeder, they’ve proved to be ill-prepared for life with a new pet, and the pet itself has found it hard tocome to terms withlife in a new home.Looking to the future, there are concerns about the welfare of these much-loved pets. Lan Alkin manager of the Oxfordshire Animal Sanct uary in the UK, notes: “At the moment, the dogs are having a great time, but separation anxiety could still surface when people go back to work.” And Cliare Calder from the UKs Dogs Trust rescue charity says, “The economic situation also means that some people may find they can’t afford to look aftera dog.” The message is not to buy a dog in haste and to pick one that fits into our lifestyle.1. The greater demand for dogs can cause the following problems except ________.A. illegal trade of dogsB. less dog farmingC. high prices of dogsD. online sale of dogs2. What does the underlined phrase"come to terms with"in paragraph 4 mean?A. Fit in withB. Go in forC. Make up for.D. End up with3. What can we learn from the last paragraph?A. Despite the problems, dogs are living happily.B. The writer has a positive attitude towards dogs future.C. Experts are worried that dogs will be unaffordable to people.D. The writer advises people to think twice before keeping dogs as pets.BJIANLI, Hubei Province, June 2 (Xinhua) — A cruise ship carrying more than 450 people sank in the Yangtze River overnight, which could be China’s worst sinking disaster in decades. As of 6 p.m. Tuesday, 14 peoplehad been rescued from the capsized vessel, with five others confirmed dead. The rest are still missing, although rescuers said there could be more survivors.

But rarely does a young person get to meet or talk to their idol. Yet for one young tennis player - Coco Gauff - her chance to do just that happened in an amazing way!Coco was born on March 13, 2004. At the age of 4, she developed an interest in tennis after watching Venus Williams win the Australian Open on TV. Coco began playing at 7 and showed a real talent for the sport. When young Coco turned 10, she began training at a tennis centre run by Venus's coach, Patrick Mouratoglou. He still remembers the first time he met Coco. He says, “She impressed me with her determination and fighting spirit. ” Convinced of her talent, Mouratoglou sponsored（资助）Coco to attend his academy in France. While she was preparing to go to the academy in 2019, she received a call that would change her plans and her life!Wimbledon（温布尔顿网球比赛）organizers called and offered Gauff entry to the tournament（联赛）as a wildcard（外卡选手）.This madeher one of the youngest players to ever qualify.

The tennis legend is 24years older than Gauff.The world watched with amazement as young Gauff beat Venus in two straight sets! Afterwards, Gauff shook Venus's hand, thanked her and said, “I wouldn't be here if it wasn't for you. " After the match, Venus said of Gauff, “I think the sky is the limit；it really is.

They are macaque monkeys. They have taken over the old city ofLopburiinThailand. About 8,400 of them are in the center of the city. They roam(漫游) neighborhoods in groups. Dozens of businesses in Lopburi are closing. They include a music school, a gold shop, a barber, a cellphone store and a movie theatre. The Buddhist culture believes reducing the number of monkeys would disturb spiritual well-being.The monkeys were not always such a hazard. They attracted tourists. Buddhists thought feeding them was a good deed. Now times have changed. Recently, the coronavirus made things worse. There are fewer tourists, which means that travelers give less food to the monkeys. Over the years, the monkeys moved into empty buildings. They trashed whatever they came across. They ripped(扯掉) antennas and windshield wipers off parked cars. What happens when monkeys come into contact with humans? An observer said that years ago the monkeys were fewer, biggerand healthier. Their fur was shiny and thick. They kept to the temples，as well as the ruins of the ancient Khmer civilization.Then tourists came with easy and unhealthy food. Along with bananas and citrus(柑橘), the macaques feasted on junk food. An observer said, “The monkeys are never hungry. They are just like children who eat too much KFC. ” Compared with the monkeys of the forest, their urban counterparts have less muscle. They have more hypertension and blood disease. Their fur has thinned. Some have gone bald. With so much food available，they have more time to breed and to give birth. Their population has exploded. “These monkeys were here before us,” a man said. A juvenile macaque tugged(拽) his trousers demanding a treat. “We have to adapt to them，not the other way around. ”12. Why are macaque monkeys so popular in Lopburi inThailand?A. Because they are smart and know how to steal.B. Because they have taken over the old city ofLopburiinThailand.C. Because they are symbols of spiritual well-being in the Buddhist culture.D. Because 8,400 of them are in the centre of the city and roam everywhere.13. In what way has tourism influenced the macaque monkeys?A. The monkeys are bigger and healthier.B. The monkeys like eating KFC food.C. The monkeys have suffered from more diseases.D. The monkeys are subject to birth control.14.

NOK 120.BIn the Pacific Northwest during winter, 5:15 am might as well be the dead of night. The alarm goes off and the onlylight is the red glow from my clock. My body says, “Go back to bed.” But I don’t. I know my running partner will be waiting in the street and I’m not going to stand her up. Then I walk onto the road, complaining about the cold and wishing I were back under my warm covers.If you’d have asked me a year ago if I could see myself running at 5:15 on a winter morning, I’d have laughed. Morning just wasn’t my thing and running in the morning was something I didn’t even consider. “I prefer to work out in the middle of the morning or in the afternoon,” I’d say to my friends who go to the gym before work.Then, last fall I reconnected with an old neighborhood friend. She’d been running in the morning and taken off forty pounds that year. When I looked in the mirror, I knew I could benefit from the same kind of weight loss. I asked if I could join her. I knew I needed to change something if I was going to get back in shape.The first two months were especially hard, because we ran twice a week at 5:15 am and I slept till 7:00 the other mornings. But as I’ve adjusted to the routine of running, I’ve discovered great joys that make it even more worthwhile than a little weight loss.While I haven’t lost forty pounds yet, it’s amazing how much more energy I have and how much stronger I feel. Because of the morning run, the rest of my day is more productive. I wouldn’t say I’ve become a morning person, but I would say morning running is now my thing.4. What can we know about the author from paragraph 1?A. 5:15 is the ideal time for her to exercise.B. She prefers to run without any company.C. She takes the run with warm clothes on.D.

Comedian Caitlin Reilly used the app during quarantine (隔离) to make fun of those annoying coworkers for one of the top liked videos. And singer Curtis Roach made an song for the endless days at home with his song Bored in the House.The second most popular video was an Idaho man named Nathan Apodaca who shot to fame after coolly singing Dreams by Fleetwood Mac, while skateboarding on a highway.But the most liked TikTok video was awarded to Bella Poarch with 45 million followers, who created a simple but interesting video with a few seconds of well-timed head nods and eye rolls.While the app might be designed for youth, Chikumbu said that the growth of TikTok this year has pushed itmore into mainstream culture. “You're seeing everyone from the teenager to the college students with their parents and then their grandparents all making videos,” said Chikumbu. “And now TikTok trulytranscendsgenerations, particularly in this year when people had a lot of time to dig in and not only watch, but try.”8.

Takes charge of.DThere are 195 countries in the world today but almost none of them have purple on their national flag. So what’s wrong with purple? It’s such a popular color1 today. Why would no country use it in their flag? The answer is really quite simple. Purple was just for too expensive.The color1 purple has been associated with royalty power and wealth for centuries. Queen Elizabeth I forbade anyone except close members of the royal family to wear it. Purple’s high status comes from the rarity and cost of the dye (染料)originally used to produce it. Fabric traders got the dye from a small sea snail (海螺)that was only found in the Tyre region of the Mediterranean. More than 10,000 snails were needed to create just one gram of purple; not to mention a lot of work went into producing the dye, which made purple dye so expensive.Since only wealthy rulers could afford to buy and wear the color1 , it became associated with the royal family. Sometimes, however, the dye was too expensive even for royalty. Third century Roman Emperor Aurelio famously wouldn’t allow his wife to buy a scarf made from purple silk because it cost three times its weight in gold. A singlepound of dye cost three pounds of gold, which equals 56,000 dollars today. Therefore, even the richest countries couldn’t spend that much having purple on their flags.The dye became more accessible to lower-class about a century and a half ago. In 1856, 18-year-old English chemist William Henry Perkin accidentally created a man-made purple compound (化合物)while attemptingto produce an anti-malaria drug. He noticed that the compound could be used to dye fabrics, so he patented the dye, manufactured it and got rich. Purple dye was then mass-produced so everybody could afford it.Till now, a handful of new national flags have been designed and a few of them have chosen to use purple in their flag. So don’t be making any bets just yet.12. Why was color1 purple expensive in the past?A. Because only royal families were allowed to wear purple.B. Because it took a long time to get purple dye from gold.C. Because purple was worth as much as its weight in gold.D. Because purple dye used to be rare and hard to produce.13. Why did Roman Emperor Aurelio forbid his wife to buy a purple scarf?A. Because of poor quality.B. Because of long tradition.C. Because of bad taste.D. Because of high price.14. What is purple's situation now?A. Purple has been widely used on national flags.B. Purple dye is now affordable to ordinary people.C. Royal family stop using purple because it’s toocommon.D. Fewer snails are used to produce purple dye than before.15. Which of the following would be the best title for the passage?A. No Purple Flags?B. Purple vs GoldC. How to Produce Purple Dye?D.
