2020-2021学年甘肃省榆中县第一中学高三语文上学期期末考试试卷及参考答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字,完成下题。

①碧蓝的天空，铺过来一层蚕丝般的云幕，不一会儿，太阳周围现出一道彩色光环。

它宛若彩虹，但没有彩虹鲜亮；虹的色彩排列是内紫外红，而光环刚好相反，是外紫内红。

这就是“晕”，俗称“风圈”。

②我们的祖先，很早就对“晕”进行了观察和记载。

远在殷墟甲骨文中，已有“晕”字出现。

到了西周，“晕”便正式作为天象被记录下来。

而欧洲人直到1630年，才有关于“晕”的详细记载，比我国晚了一千多年。

③人们虽然很早就注意到了这种美丽的光象，但对它的成因作出科学的解释，则是近一二百年的事。

1666年，牛顿做了一个很简单的但对后来科学发展影响很大的实验。

他让一束阳光透过三棱镜，结果出现，红、橙、黄、绿、蓝、靛、紫的七色彩条。

这使人类第一次认识到，阳光原来是由七种不同颜色的光组成的，当它们通过三棱镜时，由于波长、折射角不同，才显示了各自的本色。

这一发现，给“晕”的科学解释打下了基础。

④探空资料表明，那白如蚕丝的云幕，其高度都在距地面5000米以上，是由六方柱体状的小冰晶组成的。

如果把六方柱体不相邻的边延长，实际上就是三棱柱体。

所以，六方柱体状的冰晶就像三棱镜一样，能把阳光分成七色彩条。

当无数兆亿小冰晶被阳光照射后，各色光按一定角度折射出来，便形成了绚丽多彩的晕环。

⑤人们对“晕”的兴趣，不单因为它有斑斓的色彩，而且由于它是天气变化的一种前兆。

据我国新疆阿勒泰地区统计，在1980天中就曾出现过1052次“晕”，“晕”后两天内出现风、雨等显著天气变化的占80％。

⑥不过，也不是所有的“晕”都是风雨之兆。

气象工作者经过长期观察发现：当“晕”的持续时间在1小时以内(俗称“短晕”)时，未来的12小时—36小时内会出现风或雨；当“晕”的持续时间在5小时以上(俗称“长晕”)时，则不会有风雨天气出现。

Paige Lewis.3. Where is the text most likely from?A. A diary.B. A brochure.C. A website.D. A magazine.BA Bridge Linking Art and the AudienceAccording to a 2018 report, people aged between 16 and 24 make up about 15 percent of the population but only 10 percent of museum-goers. Similarly, people aged over35 go half as much as you would expect from their population size. We have reached the point of recognising the disconnection between art and the audience but haven’t yet determined how to bridge the gap. Two answers to tackling this challenge lie in telling a greater diversity of art histories and communicating these stories in more accessible ways.In 2018, a radio program called Art Matters was started with the aim of discussing art from a pop-culture viewpoint with topics that would engage younger and more diverse audience. It offers an accessible pathway to art history with conversations on different topics. Art history is about storytelling; art content shines when there is an effort to bring audience along for the discussion.More traditional institutions are paying attention. Recently theGettyMuseumissued a social-media challenge for people to recreate paintings using items they had at home. Users displayed incredible creativity, and the museum was flooded with submissions. This reaction proves that there is a potential desire for the audience to engage with art topics if the format is appealing. Since many people feelintimidatedand think that there’s a base level of understanding required to join the conversation, the Getty initiative serves as a reminder that there are many pathways to engaging with it.Another result of the Getty challenge was the exposure given to a diversity of artworks. The famous opera singer Peter Brathwaite, for example, made scores of attractive recreations highlighting centuries of black paintings. His efforts opposed the idea that there were not many historical paintings of black figures. It is extremely important that we do a better job of showing the complex and diverse stories that are represented in art.Social media have offered a platform for people who have not traditionally had a seat at the table. Anyone can recognise a gap in the field and address it. Accounts have gathered tens of thousands of followers. They are the proof that there is hunger to hear these art histories, and these themes work brilliantly for museum programming.But there is only so much that can be done without the museums and galleries changing meaningfully fromwithin. We need to see a better balance of these stories represented in permanent collections. We also need a much wider diversity of people and interests represented on board. Ensuring that art-and writing and talking about art-is able to continue on the rising generation of storytellers, inside and outside of institutions, getting the funding and support they need to paint a brighter picture for the part.4. What challenge is the author trying to tackle?A. People doubt a great diversity of artworks.B. Fewer and fewer young people go to museums.C. Art appears too distant from common audience.D. Adult audience has a different understanding of art.5. What does the underlined word “intimidated” in Paragraph 3 probably mean?A. Tired.B. Worried.C. Annoyed.D. Surprised.6. In the author’s opinion, the museums and galleries should ________.A. make the art history stories accessible in a traditional way.B. change meaningfully for activities like the Getty challenge.C. limit the number of storytellers both in and out of institutions.D. improve the permanent collections by adding famous artworks.7. We can conclude from the passage that common audience ________.A. lacks the channels to understand and talk about art history.B. prefers to view artworks and hear art stories on social media.C. feels satisfied with people and interests represented on board.D. refuses to engage with diverse art topics and art history stories.CIn many countries of the world, people can confidently tell youthe meaning of their town or city, but most people who live inManchester,OxfordorBirminghamwould not be able to explain what the name of their city means. The name of every British town and city, however, has a long history.Two thousand years ago, most people living inBritainwere Celts. Even the word “Britain" is Celtic (凯尔特语).Then the Romans arrived and built camps which became cities called “castra". This is why there are so many place names inEnglandwhich end in "-chester" or “-caster"Manchester, for example.The Romans never reachedWalesorScotland, and many placenames there are Celtic. For example,Welsh place names that begin with “Llan" come from the Celtic word for "church".After the Romans leftBritain, it was attacked by the Anglo-Saxons who were from the area of Europe that is nowGermanyandHolland. The names of their villages often ended in “-ham" or “-ton". Some got their names from the leader of the village.SoBirminghamfor example, means "Beormund's village”The Anglo-Saxons were farmers and the landscape was very important to them, so we have villages called Upton (village on a hill)——a good place to build a village and Moreton (“village by a lake”)where floods could make life hard. Place names that end in “-ford" (a place where you could cross a river) also describe the location of Anglo-Saxon villages.Finally, in 1066EnglandbecameNorman—theNormansgave us the place name "grange", which means farm.And how aboutLondon? Experts cannot agree. The Romans called the city Londinium, but they were not the first inhabitants (居民). People once believed that theUnited Kingdom’s capital city got its name from the castle of a King called Lud but this is very unlikely. Our best guess today is that the name comes from a Celtic word meaning a fast-flowing river. Like a number of British place names, its history is lost in time.8. The origin of British place names is unfamiliar to many local people because ofA. the death of local languagesB. the long lost history of the namesC. their lack of interest in itD. the frequent changes to the names9. According to the article,Stratfordis most likely a town .A. on a hillB. near a castleC. beside a riverD. with a church10. Which of the following shows the correct order of the arrival of inhabitants inBritain?A. The Celts—The Romans—TheNormans—The Anglo SaxonsB. The Celts—The Romans—The Anglo Saxons—TheNormansC. The Romans—The Celts—The Anglo Saxons—TheNormansD. The Romans―The Anglo Saxons—The Celts—TheNormans11. What doesLondonmean in Celtic?A. RiverB. LondiniumC. LudD. CastleDWhen I was trying to find a place where to spend my December holidays, I met by chance some cheap flightsto Iceland. After checking just a few winter pictures of Iceland, I realized that the country, known as the land of fire and ice, during the cold months of the year could offer me experiences I had never had before.For sure you can’t miss the chance to go to Iceland in winter if your traveling wish list includes at least one of the crazy experiences Iceland can offer. Iceland in the North Atlantic Ocean is a paradise (乐园) for all those who want to see the northern lights, experience cold weather conditions and put themselves in geothermal (地热的) baths while the snow is falling on their head.The best way to move around Iceland is with a rental car. Distances are huge and public transport in winter is not really common out of the major towns. As we wanted to be even more convenient we decided to rent a small camper (野营车). Sleeping and cooking in a camper saved us a lot of driving, money and gave us the chance tobe always in the right place at the right time.There were also no locals and in many cases no tourist facilities (设备). For us, as we slept in a camper, it was easier. But for tourists traveling by normal cars it is necessary to check the opening times ofhotels and restaurants as many of them run just from June to September.It is amazing to experience how the weather is changing in Iceland. However, Icelanders prefer to stay inside their houses. They have even no time to complain about the weather in December. All they care about is Christmas. They love to decorate their houses, sing Christmas songs and eat typical Christmas food.12. Why is Iceland famous as the land of fire and ice?A. Because tourists would like to play with fire on the ice.B. Because it is too dry to easily cause fire to happen.C. Because it is hot inside a house and cold outside.D. Because there exist hot springs and freezing ice.13. What did the author think of the rented camper?A. It was not only practical but also economical.B. It was convenient but cost them more money.C. It provided the best chance to see the new country.D. It was much faster than other public transport.14. What does the last paragraph imply?A. The Icelanders prefer to live with their family.B. The joy of Christmas drives the freezing weather away.C. December is the coldest month of the year.D. The Icelanders are always positive and stay outside.15. What does this passage most probably come from?A. A textbookB. A scientific reportC. A travel magazineD. A news report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。

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.4. What does the underlined word “offensive“ in paragraph 1 refer to?A. Rude.B. Creative.C. Suitable.D. Caring.5. 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.6. 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.7. Which can be a suitable title for the text?A. The Wayof Showing GratitudeB. A Fun Behavior to Respect PeopleC. Various Gift Giving TraditionsD. A Special Custom of Gift GivingCTen years ago, I set out to examine luck. I wanted to know why some people were always in the right place at the right time, while others consistently experienced ill fortune. I placed advertisements in national newspapersasking for people who felt consistently lucky or unlucky. Hundreds of extraordinary men and women volunteered for my research. Over the years I have interviewed them, monitored their lives and had them take part in various experiments.In one of the experiments, I gave both lucky and unlucky people a newspaper, asking them to look through it and tell me how many photographs were inside. I had secretly placed a large message halfway through the newspaper, saying, “Tell the experimenter you have seen this and you will win $50.” This message took up half of the page and was written in type that was more than two inches high. It was staring everyone in the face, but the unlucky people tended to miss it and the lucky people tended to spot it.Unlucky people are generally more nervous than lucky people, and this anxiety affects their ability to notice the unexpected. As a result, they miss opportunities because they are too focused on looking for something else. They go to gatherings concentrating on finding their perfect partners and miss opportunities to make good friends. They look through newspapers determined to find certain types of job advertisements and miss other types of jobs.Lucky people are more relaxed and open, and therefore see what is there rather than just what they are looking for. My research eventually showed that lucky people are skilled at noticing opportunities, make lucky decisions by listening to their intuition (直觉), are open to new experiences, and adopt a never-say-die attitude that transforms bad luck into good luck.8. What’s the purpose of the author’s research?A. To discover what luck means to people.B. To find lucky people and unlucky people.C. To distinguish between good luck and bad luck.D. To figure out why people are always lucky or unlucky.9. Why did the unlucky people miss the message in the experiment?A. There was too much information to be read in detail.B. They were too focused on looking for photographs.C. It took too much time to go through newspapers.D. The words were too small to be noticed.10. What leads to lucky people’s good fortune?A. Their ability to spot opportunities.B. Their ability to become relaxed.C. Their ability to communicate.D. Their ability to make friends.11. What’s the key message of the last paragraph?A. What lucky people are looking for.B. How lucky people generate good luck.C. What lucky people can do with opportunities.D How lucky people transform bad luck into good luck.DAccording to statistics published by the BPI (Buying Power Index) a couple of months ago, digital streaming (流媒体) now accounts for 80 percent of the music consumption in the UK. Despite the incredible growth of online streaming platforms like iTunes, Apple Music and Tidal over the past 15 years, a more traditional medium has also seen a return of interest and sales in the music industry. In 2020, almost one in five of all albums purchased in the UK is vinyl (黑胶唱片), and it has once again become the most popular physical musical medium.With digital streaming so easy and convenient, why are so many peopledrawn to traditional records? Some experts claim that vinyl is a physical medium for experiencing music, something tangible (有形的) to hold and own. For most people, having something tangible and interacting with it gives depth to the experience of music. Listening to an album and touching it the way the artist intended can make them feel more connected to the music and the artist. Records are physical products that can be not only displayed but also gifted, shared, traded and passed down through generations.Sound quality is another hot topic. A lot of music lovers feel that the analogue sound (模拟声音) vinyl offers is superior to modern digital audio, particularly with regards to the compressed formats streaming platforms use. There’s a common belief that old-school analogue audio has a warmer, fuller sound than digitised music. For vinyl followers, the very defect traditional recorders often have, such as the familiar crackle (劈啪作响) when the record starts, bring the music to life in a different way.There’s aritualisticaspect to vinyl that a lot of people are drawn to, too. The act of putting a record on—carefully removing the record from the sleeve, placing it on the record player and gently dropping the needle on the right groove (凹槽)—is a more assiduous (一丝不苟的), mindful way of engaging with music. When you’re listening to vinyl, you can’t tap abutton and go about your day while the streaming service provides hours of music. You need to stay close to the record player to move the needle and flip the record over.It’s clear that the vinyl interest is well underway, and vinyl records are truly making a comeback. In an increasingly digital society, there’s something to be said for analogue experiences. Perhaps one of the great things about being alive in the 21st century is our ability to have the best of both worlds—the timeless appeal of physicalrecords alongside the easy access to vast music libraries that streaming offers.12. What are the statistics published by the BPI used to show?A. An increase in music consumption.B. The recovery of music industry.C. A comeback of a physical medium.D. The acceptance of online streaming.13. According to some experts, why does vinyl interest many people?A. It attracts people by its realistic feel.B. It offers simple access to different music.C. It shares a new way to enjoy music.D. It provides people with perfect sound effect.14. The underlined word “ritualistic” in Para.4 means something ______.A. Overlooked by society.B. Updated very frequently.C. Performed as part of a ceremony.D. Kept for a long time without changing.15. How does the writer feel about the future development of music medium?A.

Bui now researchers are finding that video games can actually change us for the better and improve both our body and mind.Games can help to develop physical skills. Pre-school children who played interactive games have been shown to have improved motor skills, for example they can kick, catch and throw a ball better than children who don’t play video games. A study found that those who played video games were 27 percent faster and made 37 percent fewer errors than those who didn't.Games also benefit a variety of brain functions, including decision-making. People who play action-based games make decisions 25 percent faster than others, according to one study. It was also found that the best gamers can make choices and act on them up to six times a second, four times faster than most people. In another study by researchers from the University of Rochester in New York, experienced gamers were shown to be able to pay attention to more than six things at once without getting confused, compared with the four that most people can normally keep in mind.There is also evidence that gaming can help with psychological problems. At the University of Auckland in New Zealand, researchers asked 94 young people diagnosed with depression to play a 3D fantasy game called SPARX and in many cases, the game reduced symptoms of depression more than conventional treatment.4. In what way playing video games benefits very young children?A. Muscle control.B. Social interaction.C. Decision-making.D. The ability to focus.5. Which type of video game improves the decision-making speed?A. Interactive games.B. Action-based games.C. 3D fantasy games.D. Violent games.6. What is the authors attitude to video games?A. Indifferent.B. Objective.C. Worried.D. Critical.7. What is the text mainly about?A. The effects of different types of video games.B. The negative effects of playing video games.C. The beneficial effects of playing video games.D. The effects of games on people's behavior.CSalad plants have already been grown in old sheltersand tunnels. Urban farming is a regular topic of interest at places like the World Economic Forum (WEF) in Davos, where leaders consider whether the world's food system, blamed for causing both obesity and malnutrition, can be fixed. There are already plenty of urban farming projects around the world, particularly in the US, Japan and the Netherlands, from urban fish and plant farms to vertical farming.“It's becoming an expanding industry,” said Richard Ballard, one of the founders of the farm Growing Underground. “There're several other businesses starting up in London in containers, and there are other vertical farms around the country now.”Growing Underground is not a standard farm. The rows of crops could be in almost any tunnel, but these plants are 100 feet below Clapham High Street and show that urban agriculture is, in some cases at least, nota fad. The underground farm has occupied a part of the Second World War air-raid shelters for nearly five years, and Ballard is planning to expand into the rest of the space later this year.Growing Underground supplies herb and salad mixes to grocery shops, supermarkets and restaurants. Being in London creates an advantage, Ballard says, as they can harvest and deliver in an hour.He adds other advantages. Being underground means temperatures never go below 15℃surface greenhouses need to be heated. They can do more harvests: 60 crops a year, compared with about seven in a traditional farm. Electricity to power the lights is a major cost, but the company believes renewable energy will become cheaper.Similar British companies include the Jones Food Company in Lincolnshire, while in the US AeroFarms has several projects in New Jersey, and Edenworks in Brooklyn.8. What do we know about urban farming?A. It leads to a healthier lifestyle.B. It is rarely discussed at the WEF.C. Different farming methods are used.D. Local governments pay efforts to develop it.9. Which of the following best explains "a fad" underlined in Paragraph 3?A. A dream that's easy to realize.B. A field controlled for a long time.C. An approach to a serious problem.D. A fashion that’s popular for a short time.10. What can we learn about the underground farm?A. It is more productive than a traditional farm.B. It provides food directly to the customers.C. Its major products are herbs and salads.D. It uses less energy than a greenhouse.11. What can be a suitable title for the text?A. Current food system causes health problemsB. Growing Underground attracts more peopleC. Traditional farming will be replaced soonD. Urban farming isstill thought costly and time-consumingDWhile the start of a new school year is always exciting, this year was even more so for some elementary school students inAuckland,New Zealand. They became the world’s first kids to be “taught” by a digital teacher.Before you start imagining a human-like robot walking around the classroom, Will is just an avatar that appears on the student’s desktop, or smartphone screen, when ordered to come.The autonomous animation platform has been modeled after the human brain and nervous system, allowing it to show human-like behavior. The digital teacher is assigned to teach Vector’s “Be sustainable with energy”— a free program forAucklandelementary schools.Just like the humans it replaced, Will is able to instantly react to the students’ responses to the topic. Thanks to a webcam and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues. For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps attract the students’ attention, but also allows the program’s developers to monitor their engagement, and make changes if needed.Nikhil Ravishankar believes that Will-like avatars could be a novel way to catch the attention of the next generation. He says, “I have a lot of hope in this technology as a means to deliver cost-effective, rich, educational experience in the future.”The program, in place since August 2018, has been a great success thus far. Ravishankar says, “ What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention.” However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon.12. What was special for some elementary school students inAuckland?A. A digital teacher taught them.B. They first saw something digital.C. This was the start of a new school year.D. They could get close to smartphone screen.13. What is the benefit of this two-way interaction?A. It can smile back.B. It can use microphone.C. It can talk any topic for free.D. It can change if necessary.14. What’s Ravishankar’s attitude to Will’s replacing Human educators soon?A. Optimistic.B. Doubtful.C. Unclear.D. Disapproving.15. What might be the best title for the passage?A. New High-tech Contributes to EducationB. The World’s First Digital Teacher Appears in Classroom.C. The World’s First Digital Teacher, a Help to StudentsD.New ZealandWill Replace Teachers in Classrooms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。

2019-2020学年甘肃省榆中县第一中学高三英语上学期期末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.BHumans are the only creature that gets around by standing up and putting one foot in front of the other. Our ability to walk upright has allowed humankind to travel great distances and survive changing climates, environments and landscapes.Countless scientific studies have found that walking is really good for us and this simple act can provide a number of healthimplications, which help people live longer. In fact, a walking routine, if done properly, might be the only exercise people need.How much walking should one aim for? You’ve likely heard we need 10,000 steps a day. That’s about 5 miles. But contrary to popular belief, this recommendation doesn’t come from science. Instead, itis from a 1960s advertising campaign to promote a pedometer (计步器) in Japan. Perhaps because it’s a round number and easy to remember, it stuck.Since the 1960s, researchers have studied the 10,000-steps-a-day standard and have turned up mixed results. Although 10,000 steps is certainly a healthy and worthwhile goal, it’s not fit for all.For instance, a recent Harvard University study involving more than 16,000 senior women found that those who got at least 4,400 steps a day greatly reduced their risk of dying early when compared with less active women. The study also noted that these benefits continued up to 7,500 steps. This 7,500 mark isn’t surprising: It’s similar to common public health recommendations, such as the Centers for Disease Control and Prevention’s recommendation of 150 minutes of moderate (适度的) physical activity a week for adults.4. What does the underlined word “implications” in Paragraph 2 refer to?A. BenefitsB. Problems.C. Habits.D. Manners.5. Where does the 10,000-steps-a-day standard come from?A. A Harvard University study.B. Science research on health.C. A pedometer advertisement.D. Public health recommendation.6. What can we know from the last paragraph?A. 7,500-steps-a-day standard is the best choice for all.B. More than 16,000 old people were involved in the study.C. Those who walk at least 4,400 steps a day won’t die early.D. 150-minute moderate exercise a week for adults is advised.7. What does the author mainly want to tell readers?A. The more you walk a day, the healthier you will be.B. We can benefit from continuous and proper walking.C. Walking upright helps humankind to explore the world.D. Advertisements can always tell us some scientific suggestions .CChildren's average daily time spent watching television or using mobile device increased from 53 minutes at age 12 months to more than 150 minutes at 3 years, according toan analysis by researchers at the National Institutes of Health (NIH). By age 8, children were more likely to log the highest amount of screen time if they had been in home-based children or were born to first-time mothers.“Our results indicate that screen habits begin early, ”said Edwina Yeung, an investigator in National Institute of Child Health and Human Development (NICHD).“This finding suggests that interventions(干涉) to reduce screen time could have a better chance of success if introduced early.”In the research, mothers of 4, 000 children responded to questions on their kids' media habits when they were 12, 18, 24, 30, and 36 months of age.TheAmericanAcademyof Pediatrics recommends avoiding digital media exposure for children under 18 months of age, introducing children 18 to 24 months of age to screen media slowly, and limiting screen time to an hour a day for children from 2 to 5 years of age. In the current study, researchers found that 87% of the children had screen time exceeding (超过) these recommendations. However, while screen time increased throughout toddlerhood, by age 7 and 8, screen time fell to under 1.5 hours per day. The researchers believe this decrease relates to time consumed by school-related activities.The study authors classified the children into two groups based on how much their average daily screen time increased from age 1 to age 3. The first group, 73% of the total had the lowest increase, from an average of nearly 51 minutes a day to nearly an hour and 47 minutes a day. The second group, 27% of the total, had the highest increase, from nearly 37 minutes of screen time a day to about 4 hours a day. Higher levels of parental education were associated with lower odds of inclusion in the second group.8. Who use mobile device longest according to the NIH's analysis?A. 10-year-old born to first-time mothers.B. 3-year-old children in low income families.C. 8-year-old children in home-based childcare.D. 1-year-old children with parents poorly educated.9. What does the research suggest according to Edwina?A. Parents should stop their children using media.B. Parents should limit the use of digital media themselves.C. Parents should reduce their children's screen time earlier.D. Parents should avoid their children using digital media at infancy (婴儿期).10. Why does children's screen time fall when they age 7 and 8?A. They are studying at school.B. They can control themselves.C. They are tired of using them.D. They are forbidden to use them.11. Which of the following may be the best title?A. Keep Away from MediaB. Screen Habits Begin EarlyC. Urgency of Parental EducationD. Harm of Home-based ChildcareDWhen I was trying to find a place where to spend my December holidays, I met by chance some cheap flights to Iceland. After checking just a few winter pictures of Iceland, I realized that the country, known as the land of fire and ice, during the cold months of the year could offer me experiences I had never had before.For sure you can’t miss the chance to go to Iceland in winter if your traveling wish list includes at least one of the crazy experiences Iceland can offer. Iceland in the North Atlantic Ocean is a paradise (乐园) for all those who want to see the northern lights, experience cold weather conditions and put themselves in geothermal (地热的) baths while the snow is falling on their head.The best way to move around Iceland is with a rental car. Distances are huge and public transport in winter isnot really common out of the major towns. As we wanted to be even more convenient we decided to rent a small camper (野营车). Sleeping and cooking in a camper saved us a lot of driving, money and gave us the chance tobe always in the right place at the right time.There were also no locals and in many cases no tourist facilities (设备). For us, as we slept in a camper, it was easier. But for tourists traveling by normal cars it is necessary to check the opening times ofhotels and restaurants as many of them run just from June to September.It is amazing to experience how the weather is changing in Iceland. However, Icelanders prefer to stay inside their houses. They have even no time to complain about the weather in December. All they care about is Christmas. They love to decorate their houses, sing Christmas songs and eat typical Christmas food.12. Why is Iceland famous as the land of fire and ice?A. Because tourists would like to play with fire on the ice.B. Because it is too dry to easily cause fire to happen.C. Because it is hot inside a house and cold outside.D. Because there exist hot springs and freezing ice.13. What did the author think of the rented camper?A. It was not only practical but also economical.B. It was convenient but cost them more money.C. It provided the best chance to see the new country.D. It was much faster than other public transport.14. What does the last paragraph imply?A. The Icelanders prefer to live with their family.B. The joy of Christmas drives the freezing weather away.C. December is the coldest month of the year.D. The Icelanders are always positive and stay outside.15. What does this passage most probably come from?A. A textbookB. A scientific reportC. A travel magazineD. A news report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届甘肃省榆中县第一中学高三英语期末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AAs a nation, we are getting bigger and eating more. But there are effective ways to control your appetite and eat only as much as you need.Keep away from low-nutrition snacksThat means ice cream, sweets, chips biscuits, cakes and any other salty orsugary snacks you eat between meals. Although we have a tendency to eat them, you can learn to live without these unhealthy-and-fattening-additions to your diet. Try to make it a habit to eat them only when offered at social events or as a special treat.Leave half an hour between main course and dessertHaving a break between courses gives your brain time to receive the fullness signal and make you more likely to refuse the sweet stuff. And, in fact, as soon as you feel the first signals of fullness, remove your plate from the table. That will tell your brain that food time is over.Make yours a small helpingPut an end to super-sized portions. You won’t be missing out—today’s small was the medium or large of a few decade ago. Select or serve yourself a modest portion and eat it slowly enjoying the flavors. Before you know it, small will feel just right. What’s more, ordering the smaller size leads to wearing the smaller size.Distract yourselfWhen you find yourself hunting down food, even though you’re even hungry, do something else for 20 minutes. Drink a large glass of water as thirst is often confused with a desire for food. Choose something that engages your brain as well as your hands, such as writing a letter or listening to a song. You could also go for a short walk or do something that you enjoy. If you think you really are hungry, set an alarm for 20 minutes’ time and if you still want to eat when it rings, fine. If not, the urge will have passed.1. Which way suits you better if you tend to order a large portion of food?A. Distract yourself.B. Make yours a small helping.C. Keep away from low-nutrition snacks.D. Leave half an hour between main course and dessert.2. Why should you have a break between main course and dessert?A. To give people time to chat.B. To have a good appetite for sweet stuff.C. To reduce appetite for dessert.D. To give the host time to remove your plate.3. When you find yourself pursuing for food, what should you do?A. Eat some biscuits.B. Eat some sugary snacks.C. Have some soft drinks.D. Listen to a lovely melody.BAs an eco-minimalist, Su Yige has maintained an environmentally friendly and sustainable lifestyle for the past three years while studying in Canada. She takes her own bag when she goes grocery shopping and uses second-hand items as often as possible. She avoids almost all paper-related products unless she has to use a public toilet while away from home.Diligence and thrift are time-honored traditional Chinese virtues. Su's family is a good example of this, according to the native of Weihai, Shandong province. Although they have little formal “green” knowledge, her parents lead a very environmentally friendly life.For example, the family has used the same hair dryer for more than a decade, and Su remembers many of her mother's clothes from as far back as kindergarten. “As long as something can still be used, my mother will not replace it with a new item,” she said.“I frequently asked my father to bring the plastic bag back home after dumping our waste in the trash bin. He was unhappy, and argued that instead of making that request, I should go downstairs to dump the waste myself” she said. In another move, her father criticized her for doing too much shopping online. Eventually, they both made steps toward becoming better environmentalists. Her father brings the bag back for reuse and she has only bought two pieces of clothing online in the past six months.Back in Canada, Su is looking forward to finding a job related to sustainable development in China after she graduates as a computer science major in the summer.4. Which of the following best describes Su Yige?A. Conservative.B. Nostalgic.C. Economical.D. Productive.5. What can be found about Su's mother according to the third paragraph?A. She has a lot of formal green knowledge.B. She regards using the same items as a lifestyle.C. She always wears old clothes due to lack of money.D. She will not replace the old items until they are out of style.6. What can be inferred about Su and her father?A. Both of them like to criticize each other.B. Su's father is particular about her clothes.C. The relationship between them is very tense.D. They urge each other to become more environmentally friendly.7. What can we learn about the author soon after she graduates in Canada?A. She will stay there to look for a job.B. She will put effort into computer science.C. She will devote herself to her motherland's future.D. She will come back to China to stay with her parents.CThe connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conductedin Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.The engineers at the Massachusetts Instituteof Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater.＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.8. What is the first paragraph mainly about?A. A new study of different plants.B. A big fall in crime rates.C. Employees from various workplaces.D. Benefits from green plants.9. What is the function of the sensors printed on plant leaves by MIT engineer?A. To detect plants’ lack of waterB. To change compositions of plantsC. To make the life of plants longer.D. To test chemicals in plants.10. What can we expect of the glowing plants in the future?A. They will speed up energy production.B. They may transmit electricity to the home.C. They might help reduce energy consumption.D. They could take the place of power plants.11. Which of the following can be the best title for the text?A. Can we grow more glowing plants?B. How do we live with glowing plants?C. Could glowing plants replace lamps?D. How are glowing plants made pollution-free?DRemember when your mom told you not to eat too many candy bars or sweets because they can cause tooth decay (蛀牙)? However, it turns out that chocolate can be moresalutaryto your teeth than you might expect. Recent studies show that chocolate can effectively fight against tooth decay, as if we need another excuse to eat chocolate.Chocolate offers protection like fluoride, a main ingredient in most household toothpastes. Not only does chocolate protect our teeth, but it can do so very effectively. Studies show that chocolate has compounds that provide strong protection for teeth. One of the compounds in chocolate, CBH, is shown to protect even more effectively than fluoride.Tooth decay happens when bacteria work to turn sugar into acids in our mouth. This is why eating foods with high sugar content can lead to more tooth decay. The compounds in chocolate, however, are anti-bacteria and can fight against bacteria in your mouth. The CBH compound in particular also works to strengthen tooth enamel (牙釉质), andprotects against tooth decay.Does this mean you can cat as much chocolate as you want without worrying about your teeth? It depends on the types of chocolate that you like. The protective effect of chocolate is most effective when you chew on cocoa beans. Of course, this option is not very appealing to; most people. A more tasty option is to choose dark chocolate with little sugar content, ideally no more than 6 to 8 grams per serving. For other types of chocolate with higher sugar content, the effect will be lessened. However, because of the protective compounds, it is still better for your teeth than other sweets and desserts containing the same amount of sugar.12. The word “salutary” in paragraph 1 means?A. Beneficial.B. Harmful.C. Familiar.D. Useless.13. What can we know about the compound CBH in chocolate?A. It can help chocolate cure tooth decay.B. It can effectively stop teeth from decaying.C. It may protect teeth better than toothpastes do.D. It may soon replace most household toothpastes.14. How does chocolate fight tooth decay?A. By breaking down acids.B. By building up compounds.C. By fixing up tooth enamel.D. By fighting against bacteria.15. What's the main idea of the text?A. Chocolate plays the role of toothpaste.B. Chocolate protects against tooth decay.C. Chocolate is the best choice for teeth protection.D. Chocolate is healthier to teeth than other sweets.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。

He has always wanted to travel. “I guess I am a really restless spirit.I like traveling, so when the chance came, I jumped at it,” he says.The chance came in the form of a newspaper advertisement for work on cruise ships（游船）. At the time Estrella was the housekeeping manager at a Melbourne hotel. He applied and, after two interviews, a medical check and police clearance, the job was his.Estrella is responsible(负责的)for the cleanliness of the ship, making sure that 160 crew work properly. “I enjoy it because there is no other work-you wake up each day in a different place anda different culture. It’s exciting when you go to the next country and you don’t understand the language,” he says.Estrella likes being busy and getting to know people from all over the world. The 1,000 crew come from 94 countries, and Estrella has learnt Spanish and a little Croatian.But there is adownside. “You cannot get really drunk...because you have safety responsibilities to yourself and others,” he says. “You don’t really think about home.You start to think about home only when you get closer to your vacation and wonder what you’ll be doing.”Life on the ship is anything but cruising. Estrella and his fellows work at least 10 hours a day, seven days a week. He warns the job is not for everybody. “You have to love being busy and be prepared to work every day-and to give up drinking too much alcohol.” In his spare time, if the ship sails into a port, Estrella explores it, otherwise he works out in the crew’s gym, goes on the internet or calls home.1.Which of the following is true?A.He has been a housekeeping manager for 18 months.B.He doesn’t drink wine now.C.He cannot speak a foreign language.D.He used to be a housekeeping manager.2.The underlined word“downside”in paragraph 5 probably means ________ .A.disappointmentB.disadvantageC.failureD.loss3.In the last paragraph, the writer thinks that life on the ship is ________.A.not a tiring journey at allB.just an interesting voyageC.far from a voyage for pleasureD.more than a pleasant travel by seaBA wife’s level of education positively influences both her own and her husband’s chances of having a long life, according to a new Swedish study.In the study, researchers from the Swedish Institute for Social Research inStockholmfound that a woman’s level of education had a stronger connection to the likelihood of her husband dying over education. What’s more, they discovered that a husband’s social class, based on his occupation, had a greater influence on his wife’s longevity(长寿) than her own class.“Women traditionally take more responsibility for the home than men do, and, as a result, women’s levels of education might be more important for determining lifestyles－for example, in terms of food choices－than those of men,” say Srs. Robert Erikson and Jenny Torssander of the Swedish Institute for Social Research inStockholm.The results show that a husband’s level of education does not influence his longevity, but that men with partners who had quit studying after school were 25 per cent more likely to die early than men living with women holding university degrees. In turn, those married to women with university degrees were 13 percent more likely to die early than those whose wives had post-graduate qualifications.According to the researchers, a woman with a good education may not marry a man who drinks and smokes too much or who drives carelessly, and men with such habits may not prefer highly educated woman. Drs. Erikson and Torssander also suggest that better-educated women may be more aware of what healthy eating and good health care consist of.The findings suggest that education has a huge impact on how long and how well people live. It also reflects social factors, since educated individuals usually have better jobs, which allow them to afford healthier diets and lifestyles, as well as better health care.4. In this passage the author intends to ________.A. present the results of a studyB. encourage women to get higher educationC. analyze the relationship between education and lifeD. discuss why women usually live longer than men5. A woman with higher education is likely to ________.A. teach her children wellB. earn more money than her husbandC. marry a man without many bad habitsD. choose a husband with a higher degree than hers6. A wife’s education has more effect on a family than a husband’s because ________.A. women make more sacrifices to their families than men doB. most women have higher degrees than their husbandsC. most men marry women with higher degreesD. women have a leading role in the home life of most families7. We learn from the passage that ________.A. a man with a lot of education lives longer than one with littleB. educated wives tend to choose healthy lifestyles for their familiesC. highly-educated women don’t marry uneducated menD. a man’s longevity depends on not only his wife’s level of education but also his ownCAccording to a survey published by the American Institutes for Research last year, a total of 57 colleges were operating some form of CBE programs and about 85 percent of all the higher education officials said they were either designing a CBE program at their school or were considering doing so.Students in a CBE program choose a central field of study, just as they would at a traditional college or university. Yet instead of attending a series of classes led by professors or teaching assistants at schools, the students study online and direct themselves.CBE programs require students to show their understanding of a given set of sills Students must prove their mastery of skills that relate to their field of choice by taking related exams. Once they have met all the requirements of their study programs, the students will get their degrees.CBE programs have made use of many new technologies, especially internet and online media. This helps reduce barriers for nontraditional and other students by bringing higher education to them. And programs that permit students to work at their own speed may save students' money by reducing the time it takes for them to earn a degree.But some educators have concerns about the value of the education that CBE programs offer. Johann NeematWesternWashingtonUniversityargues that the purpose of higher education is not simply to help students master certain skills. It should teach students how to think critically (批判性地) understand the subjects they are studying more deeply and see how they are connected to other subjects. Only that way can they put the knowledge to better use.He said, “You need to explore, think .. get shaken, have a conversation and struggle. Andthose things take time.”Instead of supporting CBE, he adds, policy makers and educators should look for ways to improve access and reduce costs for traditional higher education.8. How are CBE programs different from traditional college education?A. They require students to choose their subjects.B. They offer shorter curricula and are less expensive.C. They heavily rely on the information technologies.D. They allow students to take easier examinations.9. What can we learn from Johann Neem's words?A Free access to traditional education should be provided.B. Higher education just focuses on critical thinking skills.C. Students should spend longer time completing the degree courses.D. College students should be challenged to explore around their subjects.10. How does Johann Neem's attitude toward CBE programs?A. Supportive.B. Disapproving.C. Sympathetic.D. Uncaring.11. What is the author's purpose in writing the text?A. To press policy-makers to provide more affordable education.B. To show the disadvantages of the traditional college education.C. To introduce a new controversial trend in the higher education.D. To encourage educators to improve the quality of CBE programs.DThe first patient who died on my watch was an older man with a faulty heart. We tried to slow it down with treatment, but it suddenly stopped beating completely. Later, whenever I would have a case like that one, I found myself second-guessing my clinical management. However, it turns out that thinking twice may actually causemore harm than good.In a working paper, Emory University researchers found that when doctors delivering a baby have a bad result, they are more likely to switch to a different delivery method with the next patient, often unnecessarily and sometimes with worse results.Because doctors make so many decisions that have serious consequences, thefalloutfrom second-guessing appears especially large for us. A 2006 study found that if a patient had a bleed after being prescribed (开药) warfarin, the physician was about 20% less likely to prescribe later patients the blood thinner that prevents strokes (中风). However, if a patient was not on warfarin and had a stroke physicians were still no more likely to prescribe warfarin to their other patients.These findings highlight interesting behavioral patterns in doctors. In the blood-thinner study, doctors were more affected by the act of doing harm (prescribing a blood thinner that ended up hurting doctors were more affected by the act of doing harm(prescribing a blood thinner that ended up hurting a patient) and less affected by letting harm happen (not prescribing a blood thinner and the patient having a stroke). Yet a stroke is often more permanent and damaging than a bleed.But this phenomenon is not unique to medicine. ''Overreaction to Fearsome Risks'' holds true for broader society.For instance, sensational headlines about shark attacks on humans in Florida in 2001 caused a panic and led the state to prohibit shark-feeding expeditions. Yet shark attacks had actually fallen that year and, according to the study, such a change was probably unnecessary given the extremely small risk of such an attack happening.Humans are likely to be influenced by emotional and often irrational (不理性的) thinking when processing information, bad events and mistakes. As much as we don't want to cause an unfortunate event to happen again, we need to be aware that a worst situation that can be imagined doesn't necessarily mean we did anything wrong. When we overthink, we fail to rely on thinking based on what we know or have experienced. Instead, we may involuntarily overanalyze and come to the wrong conclusion.I have treated dozens of patients who presented with the same illnesses as my first patient, who died more than a year ago. Instead of second-guessing myself, I trusted my clinical instinct (本能) and stayed the course. Every one of those patients survived. You should trust your instinct in your life, too.12. The first two paragraphs suggest that________.A. bad medical outcomes affect doctorsB delivering babies can be difficult workC. some doctors are not very experiencedD. doctors sometimes make silly mistakes13. In the blood-thinner study, doctors________.A. tend to prescribe less effective medicineB. are more concerned about the patients' safetyC. become less confident in writing a prescriptionD. believe a stroke is more treatable than a bleeding14. What does the underlined word ''fallout'' in Paragraph 3 probably mean?A. ResultB. BenefitC. DifferenceD. Absence15. The author will probably agree that________.A. we should not doubt our own decisionsB. our experience will pave way for our futureC. humans are emotional and irrational on the wholeD. instincts don't necessarily lead to wrong directions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。
