2019-2020学年云南省玉溪第一中学高三英语月考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AThe history ofpop art begins with abstract art. Pop art emerged from the foundation of abstract art in the 1950s, first gaining recognition in Great Britain, then establishing itself in the United States in the 1960s.In the 1930s and 1940s, abstract art was greatly popular, but people began to hate this art form. Most abstract art produced in this era could be found in art galleries or the homes of the elite(名流), not in the homes of everyday people. Pop art sprung onto the scene as the people's art.Some art critics say pop art is a rebellion against abstract art; others say it is an extension of abstract art. You can see elements of abstract art in many pop art prints, especially those that consist of a collage（拼贴画）of images. However, some pop art pieces have nothing to do with abstract art, looking more like a photo of a popular consumer item, which impressed people deeply.Richard Hamilton and Eduardo Paolozzi were two of the first contemporary pop art pioneers recognised in Great Britain. They were a part of the Independent Group, an organised group of British artists who wanted to challenge ruling modernist approaches to culture. They recognised the value of modern advertising and comic book images. They used these popular images in art as a social commentary, often building irony and humour into their artworks, thus creating a new form of art. These pieces were mass-produced and sold at affordable prices.When pop art took off in the United States, it expanded to include a celebration of kitsch and the common images found in movies and television. Andy Wharhol is perhaps the most famous American pop art artist, known for his prints of the actress Marilyn Monroe, the singer Elvis Presley and of Campbell's soup cans. Andy Wharhol was inspired by images from advertisements and common consumer items. He also made a series of paintings which showed images of car accidents.1. Why did people dislike abstract art?A. People found it hard to understand.B. Ordinary people couldn't afford it.C. People disliked enjoying it in galleries.D. It wasn't based on everyday life.2. What impression do pop art works leave on people?A. They are a rebellion against abstract art.B. They have many elements of abstract art.C. They are created so real.D. They are products of advertisers.3. The Independent Group was set up to ________.A. introduce a new art form to the worldB. develop modern advertising furtherC. create new comic book imagesD. make British culture better knownBAs a basic food in the Asian diet，soybeans（大豆）have been used to make tofu and soy milk for hundreds of years．But now，they are also being turned into an alternative to plastic wrap．William Chen，a professor of foodscience and technology at Singapore's Nanyang Technological University，invented the environmentally﹣friendly food wrap．It's made of cellulose（纤维素），a form of fiber，obtained from the waste generated by soy bean product producers．The beans are pressed tosqueeze out juice that's used to make tofu and soy milk．And what's left is usually thrown away，but Chen takes the waste and puts it through a fermentation（发酵）process，during which cellulose is produced．Cellulose﹣based plastic wraps have been on the market for a few years，but Chen says that most are made from wood or corn，grown for that purpose．By contrast，his wrap is made from a waste product，which doesn't compete with other crops for land and is more sustainable．Chen's technology could help to solve two problems at once：cutting plastic production and reducing the amount of food waste．"In Singapore，the amount of food waste generated every year could fill up 15，000 Olympic﹣sized swimming pools，" Chen says．F&N，a soy﹣based drinks producer，has partnered with Chen's lab and provides the product，straight from the factory．The company is conducting a study to assess whether the food wrap could complete commercially with conventional products．Chen adds，"The soy﹣based wrap costs almost nothing to makein the lab because the raw materials are free．Commercial production would involve additional expenses，such as storage and quality control，however，we have not calculated those costs yet．"Chen hopes neighboring soy﹣loving countries will be inspired bySingapore to adopt his innovation．"My dream is that our technology，which is cheap and simple，will cut plastic and food waste and create a cleaner environment，" Chen says．4. What is the second paragraph mainly about？A. The introduction to William Chen．B. The process of producing soy milk．C. The way to make soy﹣based wrap．D. The benefit of eating soy products．5. What's the biggest difference of Chen's wrap from other cellulose﹣based plastic wraps？A. It saves land for industry．B. It's more easilybroken down．C. It is made from the food waste．D. It has been put into practice for many years．6. What will commercial production of the food wrap cause？A. A lack of competitiveness．B. Poor quality of the wraps．C. A shortage of raw material．D. An increase in production costs．7. From which is the text probably taken？A. A personal diary．B. A travel guide．C. A book review．D. A scientific magazine．CMany of us in China enjoy adding chilies (辣椒) toour food, but did you know that this spicy vegetable could also be dangerous? A 34-year-oldUSman recently ended up in hospital after eating a Carolina Reaper—the spiciest chili in the world. After taking just a single bite of one, the man suffered from serious headaches in the following few days, reported BBC News.In fact, reports of stomachache and headache caused by eating spicy food are not something unusual. But if chilies are harmful, why is it that human beings are the only animals to eat this vegetable? According to the website Huanqiu, about 600 million Chinese people—almost half of the national population—are chili eaters. So what makes people love chilies so much? The human body reacts to the burning feeling that comes from eating chilies by releasing natural chemicals that “produce a sense of happiness” , noted BBC News.And the benefits go even further than just personal enjoyment. A survey conducted by the Chinese Academy of Medical Sciences found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week. The number decreased to 14 percent for those who eat spicy food six to seven times a week. And another study done by theUniversityofVermontcame to a similar conclusion. “The data encourages people to eat more spicy food to improve health and reduce death risk at an early age,” Liu Qi, a nutritionist at the Harvard TH Chan School of Public Health, told BBC News.Chilies have anti-cancer quality and the ability to increase our metabolism (新陈代谢). So, don't worry if you love spicy food. It seems that chilies are actually good for us—except for the Carolina Reaper, perhaps.8. The example of a 34-year-old American is mentioned in Paragraph 1 to prove ________.A. chiliescan be beneficialB. chilies are popular inAmericaC. chilies can be dangerousD. serious headaches can be dangerous9. Eating chilies gives people a sense of happiness by_______.A. decreasing death rateB. releasing natural chemicalsC. curing serious headachesD. providing enough nutrition10. Which of the following statement is TRUE?A. Human are the only animals to eat chilies.B. Stomachache and headaches caused by chilies is something unusual.C. The more chilies you eat, the healthier you are.D. Chilies have anti-cancer quality but it can't increase our metabolism.11. The writer wrote the passage to ________.A. warn people of the dangers of chiliesB. ask people to eat Carolina ReaperC. encourage people to eat more chiliesD. tell people the benefits of chiliesDAs I work in theLarkwhistle Garden in Dyer's Bay, Ontario, I take my time and the garden is teaching me about working with the earth. I recognize that there will be both successes and failures and there are many variables(变量)that affect them both.The quality of the seeds planted has a bearing on how the plants will grow. The weather can be too hot, too cold, or exactly right, and usually varies between all three. Weeds seem to grow in the garden and need to be taken care of, pulled, and removed to ensure they do not eat into the fruits, vegetables, and flowers we have so lovingly planted.I take time to stand back and rest, and to observe the plants and how they are growing. Each plant is unique and develops in the way that is best for them. Some have large broad leaves to shadow their fruit from the severe rays of the sun, while other plants are more open, their fruit needing the light to grow and ripen.Getting my hands dirty, feeling the sweat on my forehead, and the strength and flexibility of my body as I dig, bend and work under the warm summer sun, reminds me I am alive in ways I would not have remembered sitting on the couch.It is attractive to move things around, to transplant, and to disturb the natural order of how plants grow. The garden teaches me that it is important to know when to disturb things and when to let them be. The garden's life cycle follows a pattern that is repeated according to laws of nature, birth, growth, and then dies and it teaches us to accept this fact.12. How many variables may affect the growth of plants in the garden?A. Two.B. Three.C. Four.D. Five.13. What can we learn about the author?A. He feels exhausted while gardening.B. He enjoys life from working practice.C. He takes pleasure in harvesting fruits.D. He dreams away his time in the garden.14. How is the garden tended by the author?A. Its rank grass is got rid of.B. Its plants are left to grow freely.C. Its temperature is controlled properly.D. Its plants with large broad leaves are cut off.15. What fact does the author learn from gardening?A. Life takes its course.B. Hard work benefits health.C. Time is short and precious.D. Gardening brings good harvest.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。

An 85-year-old primary school has been lifted off the ground in its entirety and relocated using new technology named the “walking” machine.In the city’s latest effort to preserve historic structures, engineers used nearly 200 mobile supports under the five-story building. The supports act like robotic legs. They’re split into two groups which in turns rise up and down, imitating the human step. Attached sensors help control how the building moves forward.TheLagenaPrimary School, which weighs 7,600 tons, faced a new challenge — it’s T-shaped, while previously relocated structures were square or rectangular. Experts and technicians met to discuss possibilities and test a number of different technologies before deciding on the “walking machine”.Over the course of 18 days, the building was rotated 21degrees and moved 62 meters away to its new location. The old school building is set to become a center for heritage protection and cultural protection. The project marks the first time this “walking machine” method has been used inShanghaito relocate a historical building.In recent years,China’s rapid modernization has seen many historic buildingsrazedto clear land for skyscrapers and office buildings. But there has been growing concern about the architectural heritage loss as a result of destruction across the country.Shanghaihas beenChina’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings in the famous Bund district and 19th-century “Shikumen” houses in the repaired Xintiandi neighborhood has offered examples of how to give old buildings new life. The city also has a track record of relocating old buildings. In 2018, the city relocated a 90-year-old building in Hongkou district, which was then considered to beShanghai’s most complex relocation project to date.4. How did the primary school get moved?A. By reducing the weight of it.B. By using movable supports.C. By dividing it into several parts.D. By using robotic legs.5. What does the underlined word “razed” probably mean in Paragraph 5?A. Replaced.B. Burnt.C. Protected.D. Destroyed.6. What can we infer about the heritage preservation inChina?A. The use of advanced technology leads to growing concern.B. Shanghai is the pioneer in preserving architectural heritage.C.A number of old buildings have been given new life.D. Many historic buildings will be relocated.7. What is the passage mainly about?A. New preservation campaigns are launched inChina.B. New technology gives new life to historic buildings.C. A building inShanghai“walks” to a new location.D. “Walking machine” makes heritage protection simpler.CBob, a Burroughs junior high school football player, always had his mom cheering him on. He didn’t play exciting positions. He played as a linebacker(中后卫球员). Sadly, he often found himself at the bottom of the piles, where everyone would jump onto each other at the end of every play. Bob's mom realized it was hard for her son to hear her cheering. She hadto find a solution, but couldn't find one.Then one day the coach from the school team asked him if he wanted to join the team. Bob wasecstatic, because he was only a ninth grader. His mom was also excited, since she loved football and especially loved watching her son play. She kept considering a way for him to hear her. A cowbell! That was it. Now from the bottom of the piles Bob would hear his mom shaking her cowbell crazily, knowing she was there for him.Bob's team finally made it to the state championship game. What exciting time to play at Busch Stadiumunder the lights! This experience made Bob appreciate all the years that his mom had sacrificed everything to get him to practice every day, to wash his uniforms, and to never miss a game. He had to do something.On the night of the state championship game, the loudspeakers introduced Bob, and as he walked onto the field his mom shook the cowbell, hard. However, it didn’t sound right. She looked its inside, and found a note saying,”Thank you, Mom.” Bob had left her a note expressing his appreciation for always being with him, filling her heart with warmth.Finally Burroughs claimed the title of State Champion. While others were cheering and admiring the state championship cup, Bob' s mom clutched(紧握) her cowbell happily.Years later, Bob’s mom died. While digging through her belongings, he found the cowbell with the note. Bob took it to his mom's funeral and rang it, whispering, "Thank you, Mom.”8. What does the underlined word "ecstatic” mean in Paragraph 2?A. CuriousB. DisappointedC. AnxiousD. Delighted9. Why did Bob's mom want to get a cowbell?A. To amuse her cow.B. To teach her cowC. To attract his attention.D. To make him hear her10. What can be learned from Paragraph 3?A. Bob's mom devoted much time to himB. Bob was the best player in his teamC. Bob owed his success to his coachD. Bob's mom was a football player at college11. Why didn’t the cowbell sound as usual that night?A. The mother was very weak.B. Bob had put a note inside the bell.C. The weather became terrible suddenlyD. The bell had been broken deliberates.DPortraits as ArtAccording to a dictionary, portraiture is “a representation (描绘) of a person, especially of the face by drawing or painting alikeness.” However, this definition neglects the complexities of portraiture. Portraits areworks of art that engage with ideas of identity rather than just a likeness. These concepts of identity involve social rank, gender, age, profession, character of the subject, etc. It is impossible to copy all the aspects of identity. Therefore, portraits reflect only certain qualities of subjects. Portrait art has also undergone significant shifts in artistic practice. The majority of portraits are the outcome of current artistic fashions and favored styles. Therefore, portrait art is an art category providing various engagement with social, psychological, and artistic practices and expectations.Since portraits are different from other art categories, they are worthy of separate study. During their production, portraits require the presence of a specific person, or an image of the individual. In many instances, the production of portraiture has required sittings, which result in interaction between the subject(s) and the artist throughout the creation of the work. In certain instances, portrait artists depended on a combination of different involvement with their subjects. If the sitter can’t sit in the studio regularly, portraitists could use his or her photographs. InEurope, during the seventeenth and eighteenth century, the sitting time was sometimes decreased by focusing only on the head. Theoretically, portraitists could work from impressions or memories when creating a painting, but this rarely occurred according to documented records. Nonetheless, whether the work is based on model sittings, copying a photograph, or using memory, the process of painting a portrait is linked with the model’s attendance.Furthermore, portrait painting can be distinguished from other artistic categories by its connection with appearance, or likeness. As such, the art of portrait painting got a reputation for imitation instead of for artistic innovation. Based on Renaissance art theory, portraiture was related to the level of a mechanical exercise as opposed to a fine art. Michelangelo’s well-known protest against portraits is only one example. During the nineteenth and twentieth centuries, the attitude to portraiture was critical. Even so, artists from around the globe persisted in painting portraits despite their theoretical objections. Picasso, for example, became widely-known forcubist still-life painting(立体派静物画) early in his career, but some of his early experiments in this new style were his portraits of art dealers.12. What does paragraph 1 mainly tell us?A. The changing definition of portraiture reflects shifting attitudes to it.B. Most portraits reflect artistic fashions and favored styles when created.C. Portraiture is a more complex art form than is defined in a dictionary.D. Portrait art shouldn’t be seen as a distinct art category for its complexity.13. Which of the following is a characteristic of portraiture mentioned in paragraph 2?A. Portraiture typically takes much less time than other art forms.B. Portraiture often requires frequent cooperation between artists.C. Portraits show models in a more accurate way than other art forms.D. Portraits generally involve interaction between subjects and artists.14. According to paragraph 2, during portraits’ production, artists __________.A. based their work on the subjects’ attendanceB. preferred models’ photographs to their presenceC. were more willing to use impressions or memoriesD. reduced sitting time to concentrate on a sitter’s head15. Picasso is chosen as an example by the author because he __________.A. altered the way other artists felt about portrait artB. created portraits in spite of his objection to portrait artC. depended on portrait art to establish a higher reputationD. had fewer theoretical objections to portraitures than others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。

Kids love the interactive World Brooklyn, a small cityscape（城市风光）lined by stores where children can pretend to be working grown-ups.Children's Museum of ManhattanLooking for interactive art that welcomes curious minds? Then head to Inside Art, the current show up at CMOM, which lets your little ones climb in and over and all around the exhibits. It's ideas like this that make the 40,000-square-foot so special. Learning about culture, history and science is a pride for kids aged six and under. CMOM also hosts classes—like Gross Biology for kids who are interested in insects-all designed with the latest child-development research in mind.DiMenna Children's History MuseumThe hands-on displays at this kid-focused arm of the New York Historical Society transport children back through 350 years of US history, with a special focus on NYC. Children are encouraged to climb around and interact with exhibits that highlight the lives of kids who grew up to become famous doctors, athletes and political figures! Little New Yorkers can get in on sing-alongs and crafts. Other family programs include cookings classes, games and story hours.Staten Island Children's MuseumStaten Island Children's Museum nurtures（培养）creativity. It offers hands-on experiences like the Block Harbor（plenty of blocks to play with!）, larger-than-life games like Connect Four and Dominoes, and even the opportunity to climb through a human-sized anthill or play firefighter at Ladder 11, so you'll find immersive（沉浸式的）fun around every corner.

On a human-sized anthill.BThe Great Barrier Reef's outlook remains “very poor” despite coral (珊瑚) recovery over the past year, Australian government scientistssaid Monday, just days before a UNESCO ruling on the site's world heritage (遗产) status.The United Nations cultural agency recommended last month that the world's largest reef (珊瑚礁) system be placed on its endangered list because of damage to the corals largely caused by climate change.The Australian Institute of Marine Science (AIMS) said the corals were now in a “recovery window” after a decade of harmful heat stress and cyclones (旋风). But such opportunities were becoming rarer due to the influence ofclimate change, the government agency, which has monitored the reef for 35 years, said in its annual report released today. “The increasing emergence of climate-related extreme weather events and starfish outbreaks is causing more severe and frequent pressures, giving the reef fewer opportunities like this to recover,”CEO Paul Hardisty said. The scientists surveyed 127 reef sites in 2021 and found hard coral cover had increased at 69 of the 81 locations surveyed in the past two years.Separate scientific research released last October found the 2, 300-kilometre (1, 400 miles) system had lost half its corals since 1995, with a series of ocean heatwaves causing mass coral death.Britta Schaffelke, research program director at AIMS, said the latest findings provided a slight hope that the reef still has the power of recovering. But she added that its future is still very poor because of the dangers of climate change and other factors that are affecting the reef.UNESCO has urged Australia to take urgent climate action but the government has long resisted calls to commit to net zero emissions (排放) by 2050. The government has said it hopes to meet the target “as soon as possible” without harming its economy, insisting dealing with climate change requires a global effort. The reef was worth about US $4. 8 billion a year in tourism for the Australian economy and there are fears that an “in danger” listing could weaken its tourist appeal.4. What is the major cause of the damage to the corals?A. The climate change.B. Lack of money.C. Over development.D. Too many tourists.5. What is mainly talked about in Paragraph 3?A. The result of the survey.B. The efforts AIMS has made.C. The slight chance of the recovery.D. The terrible situation of the climate.6. What is Britta Schaffelke's attitude towards the future of the reef?A. Unclear.B. Positive.C Intolerant. D. Anxious.7. What can we infer from the last paragraph?A. Australia wants to put the reef on the endangered list.B. The Australian government has ignored UNESCO's demand.C. Australia hopes to keep a balance between emission target and its economy.D. The Australian government refuses to take its share of responsibility of climate change.CSome years ago a young man applied to a large United States optical firm for a job as a lens designer. He apologized for lack of training, but on announcing that he owned two copies of the classic Conrady's Applied Optics and Optical Design, one for his office and a second for his bedside table, he was hired on the spot. Perhaps the story will be repeated some day with Buchdahl's Introduction to Hamiltonian Optics as a similar certificate of qualification.Hamiltonian theory describes with powerful generality the overall properties of optical systems considered as ‘black boxes’, although it does not describe the detailed structure needed to construct the systems and achieve these properties. Buchdahl's book is therefore on the subject of geometrical optics, but it is not about how to design lenses. It is, however a compact comprehensive account of the fundamentals of the theory written with the lens designer's needs very much in mind. Every lens designer worth his salt has at some time in his career attempted to apply the broad concepts of Hamiltonian optics to the solutions of practical problems. Success has been sufficiently rare that the theory, as such, has made little direct contribution to techniques for optical instrument design. The failures have been frustrating because of the obvious fundamental power of the theoryand because of its conceptual elegance. The indirect effects have been large, however, both in contributing to an understanding of fundamental principles that govern the overall behavior of optical systems and in pointing the way to other, more practical, theoretical approaches.Buchdahl approaches the subject not only as a capable mathematical physicist, but as one who with a knowledge of practical optics has made a significant contribution to geometrical optical theory. Buchdahl's approach has, over the last decade, had a major impact on modern lens design with computers. Thus, he brings to this exposition of Hamiltonian optics a familiarity with practical optics not usually found in authors on this subject.The author claims his book to be non-mathematical, and indeed it might be so viewed by a professional mathematician. From the point of view of many physicists and engineers, it will appear to be quite mathematical. Moreover, this is a tightly written book. The subject matter is developed with precision, and the author expects the reader, at very point, to be master of the preceding exposition.8. Hamiltonian theory met with failures as a result of ______.A. newer finding related to the wave particle nature of lightB. very complicated concepts too difficult to understand by most lens designersC. too much mathematical detail in the theoryD. not enough practical information offered by the theory to allow for use by lens crafters9. The author of this passage implies that Introduction to Hamiltonian Optics is necessary to ______.A. the students who are major in mathematical geometryB. those who want to grasp the basic principles of optical systemsC. the lens designers who look for instructions on practical designsD. those who are interested in physics10. The article points out that the great benefits of Hamiltonian optics have been found is ______.A. indirect ways of learning mathematicsB. a fundamental power within the theoryC. the conceptual elegance of the theoryD. the practical applications of the theory in finding new approaches to old problems11. This passage is probably excerpted from ______.A. a review of a bookB. a chemistry textbookC. an optician's essayD. a general science textDRemember 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.
