2019-2020学年瑞昌市第一中学高三英语第一次联考试题及参考答案

2019-2020学年瑞昌市第一中学高三英语第一次联考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ANo one knows when the first printing press was invented or who invented it. but the oldest known printed text originated in China during the first millennium (千年) AD.The Diamond Sutra (《金刚经》), a Buddhist book from Dunhuang, China during the Tang Dynasty, is said to be the oldest known printed book.The Diamond Sutrawas created with a method known as block printing (雕版印刷), which used boards of hand-carved wood blocks in reverse.It was said that the moveable type was developed by Bi Sheng. He was fromYingshan,Hubei,China, living from 970 to 1051 AD. His method replaced panels of printing blocks with moveable individual Chinese characters that could be reused. The first moveable Chinese Characters were carved into clay and baked into hard blocks that were then arranged onto an iron frame that was pressed against an iron plate.The earliest mention of Bi Sheng’s printing press is in the bookDream Pool Essays, written in 1086 by Shen Kuo, who noted that his nephews came into possession of Bi Sheng’s typefaces (字体) after his death. Shen Kuo explained that Bi Sheng did not use wood because the texture is inconsistent (不一致的) and absorbs wetness too easily.By the time of the Southern Song Dynasty, which ruled from 1127 to 1279 AD, books had become popular in society and helped create a scholarly class of citizens who had the capabilities to become civil servants. Large printed book collections also became a status symbol for the wealthy class.1. When was Bi Sheng’s printing press first introduced in history?A. After Bi Sheng died and his nephews owned his typefaces.B. When books became popular in the Southern Song Dynasty.C. After the block printing was replaced by the moveable type printing.D. WhenThe Diamond Sutrawas printed into a book.2. What can we infer from the passage?A. Shen Kuo made great contributions to printing.B. The moveable type printing was invented earlier than block printing.C. Printed books were hard to get in the Song Dynasty.D. By the Southern Song Dynasty, books had helped people get to higher social positions.3. Why does the author write this passage?A. To show that Buddhism was popular in the Tang Dynasty.B. To introduce the early history of printing.C. To memorize Bi Sheng, developing the moveable type printing.D. To indicate the advantages of moveable type printing.BPlanned missions to the moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever research on solar storm timing.Scientists at theUniversityofReadingstudied 150 years of space weather data to look into patterns in the timing of the most extreme events,which can be extremely dangerous to astronauts and satellites. This new research on space weather timing allows predictions to be made for extreme space weather. Therefore, it could be used to plan the timing of activities, which could be affected by extreme space weather, for example, major space missions.The researchers found for the first time that extreme space weather events are more likely to occur early in or late solar cycles-such as the one just starting. The findings may have influences on the NASA-led Artemis mission. It plans to make humans return to the moon in 2024, but can be put off to the late 2020s.Professor Mathew Owens, a space physicist at theUniversityofReading, said, “Until now, the most extreme space weather events were thought to berandomin their timing. Though there is no set pattern of the events, this research suggests they are more predictable.”In the new study, the scientists used a new method applying statistical modelling to storm timing for the first time. Previous research generally focused on how big extreme space weather events can be, based on observations of previous events. Predicting their timing is far more difficult because extreme events are rare, so there is ly little historic data to identify patterns. The findings suggest that any major planned space missions , which is beyond the next five years, will have to consider the higher probability of extreme space weather late in the present solar cycle between 2026 and 2030.4. What can we learn about the study from the first two paragraphs?A. It has lasted just 150 years.B. It doesn't refer to space weather data.C. It shows space weather has no effect on astronauts.D. It makes it possible to predict extreme space weather.5. Why might the NASA-led Artemis mission be put off?A. To research solar cycles.B. To avoid effects of space weather.C. To meet the needs of the astronauts.D. To make humans return to Earth in 2024.6. What does the underlined word “random“ in paragraph 4 probably mean?A. Irregular.B. Easy.C. Limited.D. Changeless.7. What can we infer from the last paragraph?A. The study is useful for future space missions.B. The planned space missions should be put off.C. Extreme space weather will happen before 2026.D. Previous observations make no difference to the study.CIn ancient times, Chinese used plant leaves or bird feathers as a fan during the summer time. This was the earliest form of the fan. The first real fan was made back in the era of Yao and Shun period thousands of years ago. Since then,Chinese-made fans have become a vital part of Chinese art and culture. At the beginning, the fan functioned as a tool to generate a current of air in the hot weather. Now electric fans such as ceiling fans and other technological breakthroughs have taken the place.Long ago, fans caught the attention of ancient Chinese artists by chance. Thereafter, a unique fan art gradually took shape in the history of Chinese culture. Fan art usually includes Chinese calligraphy, paintings, or poems on the sectors（扇区）. Special skills are needed to write or paint on them.Due to its history and partly because of its unique shape, Chinese would soon develop the tradition of using fans as ornaments（装饰品）. Fans are made in different sizes and different color1 s to meet the needs of each request. Other Chinese ornaments, such as the Chinese knot, the green jade, and the Spring Festival picture, are often combined in each design.The value of fans depends mainly on the materials used and the level of craftsmanship that is involved during the process. Feather, paper, jade, bamboo and silk have all been used as ideal materials to make fans. Ancient Chinese even made iron fans to serve as deadly weapons（武器）in Chinese martial arts. Fans made by famous craftsmen are often characterized by pretty designs and detailed workmanship, and thus become favorites of collectors. Fans with masterpiece fine art like calligraphy or paintings are even more valuable.8.What is the first paragraph mainly about?A. The origin of fans.B. The materials of fans.C. The popularity of fans.D. The production of fans.9. Why do Chinese use fans as ornaments?A. They are made of valuable materials.B. They reflect the beauty of Chinese culture.C. They convey literature works on the sectors.D. They are often combined with other ornaments.10. Which of the following makes a fan favored by most collectors?A. Its advanced function.B. Its complex character.C. Its artistic handicraft.D. Its various applications.11. What can we infer about the fan from the text?A. Chinese send fans to their friends as gifts.B. Chinese ornaments can meet different requests.C. Traditional fans have lost their functional value.D. The fan plays different roles with the change of time.DTo hear people talk about Internet friendships, you would think it was one giant web of cat-fishing and e-crime. While we all undoubtedly have to take measures to remain safe online, assuming every friendship or connection made on Instagram, Twitter or Facebook is cheating or insincere would be a mistake.As a woman who works in the creative industry, I have found real joy in seeking out a community I couldn’t find elsewhere, and making some great friends along the way. My first online friendship was on Twitter with my(now) best friend, during the university exam period. We exchanged study notes in dozens of direct messages, set a study date, and haven’t looked back since.Drawn to each other by similar circumstances, friendships online are similar to offline in that they tend to begin because of shared interest or common ground-maybe they’ve read the post on Instagram. Maybe they have the same taste in food or politics. Or maybe they just love memes too. If online friendships start similar to friendships offline, they grow in the same way, too. Often through mutual support: apart from calling a friend to congratulate him on that new job, you also re-tweet his jokes and praise his Instagram story.Despite my positive experiences when I tell people, most are still suspicious. Eyebrows are raised higherwhen I explain not only have I found a community online but have made friendships with people I meet face-to-face too. Actually, these are just as valid as other friendships, according to behavioural psychologist Jo Hemmings, who says online friendships can be real.So how do you know if people are there for the real you or just because you’re popular on Instagram? Hemmings has simple rules. She tells me “You have to equally feel comfortable that you’re getting something of each other instead of being used to enable something that isn’t friendship.”Therefore, if all a “friend” online is asking you to do is to promote their work or personal brand and rarely takes an interest in you, then there may be room to question the basis of the friendship. On that note it is worth remembering that just because someone has a lot of followers, it doesn’t necessarily mean they have lots of friends.12. What is most people’s attitude towards online friendship?A. Negative.B. Positive.C. Objective.D. Neutral.13. Why does the writer share her own experience in paragraph 2?A. To introduce the background information of the text.B. To convey the writer’s attitude and give the related example.C. To prove the likely risk for people to develop friendship online.D. To remind people of the various benefits of making friends online.14. How can online and offline friendships be deepened?A. They should be based on shared interest.B. They need to have common ground.C. They require support from each other.D. They can’t live without social media.15. According to the author, what’s the golden rule to make friends online?A. A friend to all is a friend to none.B. Without confidence there is no friendship.C. A friend without faults will never be found.D. Friendship cannot stand always on one side.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。

然而这一回，她的境遇却改变得非常大。

四叔家里最重大的事件是祭祀,祥林嫂先前最忙的时候也就是祭祀，这回她却清闲了。

桌子放在堂中央，系上桌帏，她还记得照旧的去分配酒杯和筷子。

“祥林嫂，你放着罢！我来摆。

”四婶慌忙的说。

她讪讪的缩了手，又去取烛台。

“祥林嫂，你放着罢！我来拿。

”四婶又慌忙的说。

她转了几个圆圈，终于没有事情做，只得疑惑的走开。

她在这一天可做的事是不过坐在灶下烧火。

鲁镇永远是过新年，腊月二十以后就忙起来了。

四叔家里这回须雇男短工，还是忙不过来，另叫柳妈做帮手，杀鸡，宰鹅；然而柳妈是善女人，吃素，不杀生的，只肯洗器皿。

祥林嫂除烧火之外，没有别的事,却闲着了，坐着只看柳妈洗器皿。

微雪点点的下来了。

“唉唉，我真傻。

”祥林嫂看了天空，叹息着，独语似的说。

“祥林嫂，你又来了。

”柳妈不耐烦的看着她的脸，说,“我问你：你额角上的伤痕，不就是那时撞坏的么？"“唔唔。

”她含胡的回答。

“我问你:你那时怎么后来竟依了呢？"“我么？……。

”“你呀。

我想：这总是你自己愿意了，不然……。

"“阿阿，你不知道他力气多么大呀。

"“我不信。

我不信你这么大的力气，真会拗他不过。

你后来一定是自己肯了，倒推说他力气大。

"“阿阿，你……你倒自己试试看。

”她笑了。

柳妈的打皱的脸也笑起来，使她蹙缩得像一个核桃；干枯的小眼睛一看祥林嫂的额角，又钉住她的眼。

祥林嫂似乎很局促了，立刻敛了笑容，旋转眼光，自去看雪花。

“祥林嫂，你实在不合算。

”柳妈诡秘的说，“再一强，或者索性撞一个死，就好了。

现在呢，你和你的第二个男人过活不到两年，倒落了一件大罪名。

你想，你将来到阴司去，那两个死鬼的男人还要争，你给了谁好呢？阎罗大王只好把你锯开来，分给他们。

我想，这真是……”她脸上就显出恐怖的神色来，这是在山村里所未曾知道的。

Instead, they came up with interesting games to play.★Stone ballsDuring the Qing Dynasty, kicking a stone ball around was a popular sport in the northern part of China, and it was often played in the winter to protect kids from the cold. Stones were carved into small balls and kicked along with feet. In 1999, the sport was included in the 6th National Ethnic Group Traditional Sports Meeting held in Beijing.★Flying kitesKites have quite a long history. The earliest kites were made of wood, instead of paper. Nowadays, the four most famous kites are the Beijing kite, Tianjin kite , Weifang kite and Nantong kite, of which each has distinctive features. The kite which resembles a swallow is a well-known Beijing style.★Hide-and-seekHide-and-seek is a traditional game for children, popular around the nation. There are two ways to play: covering a child’s eyes while other kids run around to tease(戏弄) him or, more commonly, participants hide and one child must try to find them.★Playing diabolosA diabolo is always made of wood or bamboo and has empty space in the center. By juggling(边抛边接) the diabolo on the rope, the high-speed spinning diabolos will make a sound like a whistle. Playing diabolos is an interesting folk game, especially popular in North China. Playing diabolos was also included in the first group of national intangible cultural heritage(非物质文化遗产).1.Why did ancient children often play stone balls in the winter?A.To practice their feet.B.To warm themselves.C.To train their skills.D.To relax themselves.2.Which kites are swallow-shaped?A.Weifang kites.B.Tianjin kites.C.Beijing kites.D.Nantong kites.3.Why does playing diabolos make a sound?A.Because the diabolo’s center is empty.B.Because the high-speed spinning diabolo is light.C.Because the diabolo is equipped with a whistle.D.Because ropes’ surface moves against the diabolo’s.BChinese paleontologists (古生物学家) have determined that, about 47 million years ago, subtropical forests once existed on the high-altitude Qinghai-Tibet Plateau.The conclusion, which appears in a paper published on Tuesday, was drawn based on the large number of fossils found in theBaingoinBasinat an altitude of nearly 5,000 meters during the second comprehensive scientific expedition to the plateau.A joint team from theXishuangbannaTropicalBotanical Gardenconducted the research on the fossils. By combining the findings and models, the team recreated the climate and altitude that existed 47 million years ago, showing that the central plateau had an altitude of just 1,500 meters and an annual average temperature of 19★, says Su Tao, a researcher from the tropical botanical garden and first author of the paper.“It was covered by thick forest and was rich in water and grass. It is fair tocall it the ‘ShangriLa’ of ancient times,” Su adds.The researchers have also found over 70 plant fossils, the majority of which are most closely related to plant life in today's subtropical or tropical regions.“This is enough to show that the central part of the now high-altitude, freezing Qinghai-Tibet Plateau had flourishing subtropical plants 47 million years ago,” Su says.The findings provide new evidence for the study of the evolutionary history of biodiversity and the evolution of the plateau's landscape, according to Zhou Zhekun, the paper's corresponding author and a researcher at the tropical botanical garden.Chinalaunched the second comprehensive scientific expedition to the Qinghai-Tibet Plateau in June 2017, 40 years after the first. Lasting up to 10 years, the expedition will conduct a series of studies focusing on the plateau's glaciers, its biodiversity and ecological changes, and will also monitor the changes in climate.4. How did the paper come to the conclusion?A. Through the observation of the Baingoin basin.B. Through the fossils found in scientific expedition.C. Through the drawing of a large number of fossils.D. Through the adventure on the Qinghai-Tibetan Plateau.5. What can be inferred according to Su Tao?A. The average altitude of the plateau was 1,500 meters.B. “Shangrila”means a place with abundant water and grass.C. The flourishing subtropical plants have covered the plateau.D. The fossils found by researchers are tropical or subtropical plants now.6. Where might the passage come from?A. The Times.B. The Wall Street Journal.C. Chinese National Geography.D. The Economist.7. What is the purpose of the passage?A. To instruct.B. To educate.C. To persuade.D. To inform.CSonja Redding and her family were on their way home to Omaha, Nebraska, after a weeklong visit to Washington, D. C. with her two sons, one of whom, 5-year-old Xayvior, has autism(自闭症).Although all of the other flights had gone fine, Xayvior became angry during one of the flights, and Redding couldn’t calm him.“It felt like everyone on the plane was looking at us and got angry with my son, ” she wrote in a Facebook post after she got home. “I don’t know what to do when others just don’t understand that he is not just a kid with no discipline(自制力)，but a child with special needs who doesn’t know how to control himself.”The day was saved by Delta flight attendant(空乘人员)Amanda Amburgy. She tried to help Xayvior watch a movie, but when that failed, she offered to take him on a tour of the airplane.That worked, and soon the child was not only calm, but having a good time.“When they came back, Xayvior was much calmer and happier,” wrote Redding in the post，which now has 2,700 likes and over 500 shares. “I want to thank this Delta attendant. She didn’t judge, and she just showed love. We need more people like this in the world. ”It wasn’t long before Amburgy was told about the post.“ We’re there to help, and that’s what we want to do,” she said in an interview. “So, we always want to make anything easier for the family as well as other passengers.”She also shared what she felt when she read Redding’s story. “When I read it, it touched my heart. It’s something I would do for anyone on the plane, because that’s what I’m here for. It really made a difference in her life.”8. How did Redding feel on the plane?A. Tired.B. Uncomfortable.C.

Which of the following words can best describe Amburgy?A. Proud.B. Honest.C. Hard-working.D. Warm-hearted.DAs every mobile-phone owner knows, after a year or so the battery starts to fade and the beast needs recharging more frequently.That is troublesome, but a phone’s batteries can be replaced fairly cheaply — or the whole device traded in for the latest model. An electric car, though, is a much bigger investment. And batteries are its priciest component, representing around 30% of an average mid-size vehicle.To provide buyers with some peace of mind, carmakers guarantee their batteries, typically for eight years or around 200,000km. Producers, planning to go much further than that, though, are racing to launch “million mile”(1.6m kilometers) batteries. Contemporary Amperex Technology, a giant Chinese firm which produces batteries fora number of carmakers, was said to be ready to start producing batteries which would last for 16 years or 2m kilometres. Elon Musk has suggested that Tesla,a Californian maker of electric vehicles, has a million-mile battery in the works.

The arts invite everyone to think in new ways.We often experience works of art as something that's pleasing to our senses without a full understanding of the creative effort. Great art often shows us contradictions and crises, and we can learn a great deal from their resolutions(解决). Through our understanding of art, we can gain a deeper understanding of how we might overcome our own challenges. In understanding extremes of contrast, we can see the beauty in art with themes that are not simply pleasing for their magnificent features or qualities.Beethoven offers a wonderful example of moving artfully through crises and chaos. He composed his Symphony No. 9 as his hearing loss became more and more pronounced. The opening of the symphony seems to come out of nowhere, from near silence in the opening to a full expression of what many consider to be the joy of freedom and universal brotherhood with Schiller’s Ode to joy（欢乐颂). Beethoven appears to have created a work of art that not only freed him from his personal struggles, but one that also speaks to the joy of living together in peace and harmony.Have a dialogue between the two opposing parts and you will find that they always start out fighting each other until we come to an appreciation of difference—a oneness of the two opposingforces.The arts offer many lessons that can help us gain the knowledge we need to move more confidently in today’ s competitive and uncertain environment. An openness to arts-based solutions will give you more control over your future.4. What value does art have beyond pleasing people's senses?A. It brings people inner peace.B.

Joy in the eyes of BeethovenCIn the natural habitat, a binge-watcher is a strange sub-species of modern human beings. They are alone and are often found lying on their bed or sofa, still as a rock, looking searchingly into their laptop or at the TV. They rarely get up, only taking occasional breaks for those urgent calls of nature. Unlike so many others of their species, they don’t sleep at the end of every day. They stay up late and are often found to have red eyes.This, of course, is a little bit exaggerated, but for many of us, binge-watching a show is how we consume our entertainment. With streaming services bringing seemingly endless content to the tips of our finger, creatorstailortheir shows to our needs and tastes, while their marketing team sells it to us as the next most bingeable show. I can’t help but wonder if this way of consuming television does us any good.We’re advised to get 7 to 8 hours of sleep per day, but staying up all night to finish shows like ‘Breaking Bad’ and ‘The Fall’, which Netflix says are binged the fastest, won’t result in 8 hours of uninterrupted sleep. Netflix’s CEO Richard Hastings told analysts at a conference, “Think about it… when you watch a show from Netflix and you get addicted to it, you stay up late at night. We’re competing with sleep.” And it isn’t only the amount of sleep we get; the quality matters too! A study published in the Journal for Clinical Sleep Medicine reported that those who binged television more often were found to have poorer sleep quality. The mental arousal we get from watching TV doesn’t lend itself to peaceful sleep.Besides, binging TV can cause weight gain. For every extra hour of TV watched, there was a 2% increase in theprevalence of obesity, according to a study conducted by Harvard that linked TV watching to obesity in children and adolescents.While it is true that there’s growing evidence that binging isn’t good for us, the results aren’t all hopeless. Binging, occasionally, might have some benefits. For many people, binging is a good way to socialize. It gives people something to talk about at parties and with their friends. Fans of popular shows often hold viewing parties where people can binge-watch shows together and then discuss what they just experienced! This interaction can create a sense of community for many.For others, binging might just be relaxing. After a long day, a few hours of Friends—still one of the most popular shows on any streaming platform—can ease the stress of a long day. A study followed 240 people through their binging and recorded their stress hormones. They noted for some people that their stress hormone levels decreased during their binging experience.With binging, there is not a “good” or “bad” answer. Like many things, the key is moderation. Watching TV can be relaxing, but only if it doesn’t stop you from exercising, taking care of your health, and fulfilling your social responsibilities.8. What does the underlined word “tailor” in Paragraph 2 probably mean?A. Study.B. Sell.C. Adjust.D. Promote.9. What can we learn from the passage?A. The amount of sleep matters more than the quality.B. There’s no real harm in binge-watching a TV series.C. Binging may help keep stress hormone levels stable.D. Binge-watching may help increase social connections.10. What is the author’s attitude towards binge-watching?A. Supportive.B. Unconcerned.C. ObjectiveD. Doubtful.11. Which of the following would be the best title for the passage?A. Who Is to Blame for Binge-Watching?B. Is Binge-Watching Good or Bad for You?C. Is Binge-Watching Getting out of Control?D. HowDoes Binge-Watching Affect Your Life?D“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, the only 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.12. Why does the author mention an old saying in the first paragraph?A. To arise reader’s awareness of upcycling.B.
