福建省福建师范大学附属中学2023-2024学年高二上学期期中考英语试卷学校:___________姓名:___________班级:___________考号:___________一、阅读理解While the benefits of Zoom and other videoconferencing tools made them absolutely essential in the pandemic (疫情), the research suggests that heavy reliance on the technology comes at a cost to creative thinking.Brucks at Columbia University and her team started their investigation when managers reported having trouble innovating with remote workers. Brucks doubted whether videoconferencing was a factor, suspecting that difficulties coordinating (协调) large, global teams online might be to blame instead.To find out, the researchers analysed ideas for new products generated by 1,490 engineers for a multinational company. The engineers, who were in Finland, Hungary, India, Israel and Portugal, were randomly paired up and given an hour or so to brainstorm products either in person or over videoconferencing. They then selected their best idea.Writing in Nature, the researchers report that the engineers produced more ideas, and more innovative ideas, when working face to face. “They are not only generating a larger number of creative ideas, but their best idea is better,” Brucks said. Virtual teams were just as good at selecting the best ideas from a bunch as those that met in person.“Visual focus is a huge component of cognitive (认知) focus. When you’re focused on the screen and ignoring the rest of the environment, that affects how you approach the task,” said Brucks. “It’s uniquely bad for creativity because it’s inhibiting broader exploration.”Brucks said the impact on the real world “could be huge”, leading to a division of labour between face-to-face and virtual meetings that could “permanently reshape the office and work schedules”. But she urged businesses to be cautious, because if virtual meetings are cheaper than in-person ones, they may still be more cost-effective.Asked for tips, Brucks said people could save more creative tasks for in-person meetings, or turn off their camera when coming up with ideas. “I think it unlocks more creative thinking,” she said.1.Why did Brucks conduct the research?A.To prove her assumption.B.To clarify a new concept.C.To make acomparison.D.To explain a rule.2.What is the finding of the research?A.Face-to-face gatherings promote cross-culture ties.B.Workers think less creatively in virtual meetings.C.Individual work generates more innovative ideas.D.Videoconferencing has an irreplaceable role.3.What does the underlined word “inhibiting” in paragraph 5 mean?A.Encouraging.B.Requiring.C.Beginning.D.Preventing. 4.What does Brucks say about virtual meetings?A.They should be used accordingly.B.They’ll make office workers divided.C.They’ll give way to in-person meetings.D.They help businesses run moreefficiently.Coral reefs (珊瑚礁) are filled with a diverse range of fish. Some fish are more beautiful to humans than others, and many people firmly believe that beautiful fish deserve more conservation than the uglier species. Is the “firm belief” true? You can get the answer from a new paper published in the journal PLOS Biology.Researchers showed 481 photographs of ray-finned reef fish to 13,000 members of the public. With that data, they then trained a computer model to generate predictions for an additional 4,400 photographs of 2,417 of the most common reef fish species. They next compared the aesthetic rating of each species with other characteristics, including evolutionary history, distinctiveness from other fish, conservation status and importance to fisheries.After analyzing the numbers, researchers found that the fish humans rated as the most beautiful tended to be less ecologically and evolutionarily distinct. Prettier fish were also more likely to be listed as species of “least concern” on the International Union for Conservation of Nature(IUCN) Red List.On the contrary, the fish that humans found to be the least attractive were the most ecologically and evolutionarily distinct, and they were more likely to be listed as “threatened” on the IUCN Red List. Unattractive species also tended to be more important to commercial fisheries, which put them at higher risk for overfishing.“The less attractive species have the highest ecological distinctiveness, and thus providethe highest diversity of ecological functions,” they write in the paper. “We need to pay more attention to the extinction risk of the less attractive fish species, or that might have overlooked effects on reef ecosystem functioning.”“Therefore, to minimize the impact of aesthetic biases, scientists, conservation groups and policymakers may need to change how they communicate about wildlife,” the researchers write. “Making people more aware of the roles uglier fish play in reef ecosystems could help them gain more support.”5.What did the researchers do for their research?A.They rated all the photos on their own.B.They hunted for reef fish in coral reefs.C.They stayed underwater to monitor fish.D.They used a computer to predict ratings. 6.What does the researchers’ analysis suggest?A.The research is a failure.B.Fish’s role in nature is equal.C.The “firm belief” isn’t true.D.Uglier fish are less important. 7.What is the researchers’ advice?A.Building natural reserves worldwide for uglier fish.B.Making an attempt to raise people’s aesthetic levels.C.Raising awareness about the appearance of uglier fish.D.Educating people on uglier fish’s ecological importance.8.What might be the best title for the text?A.Uglier Fish Are Facing Extinction B.Coral Reefs Rely on Various FishC.Uglier Fish Need More Protection D.Aesthetic Biases Put Reefs in DangerPortia Kapraun has always seen unwelcome ads on Twitter, usually from major brands pitching (竭力推销) her expensive jewelry or vehicles that she, as a librarian in Indiana, could not afford. Ms. Kapraun was not interested. But she soon saw the ads again. And again. And again. “These feel like low-end ads,” she said. In a shaky advertising market in an uncertain economy, ads that few people want to see suddenly seem to be everywhere.Advancements in digital advertising technology were meant to improve users’ experience. People interested in shoes are intended to get ads for sneakers and boots, not repeated pitches promoting gold investments. And the technology is supposed to remove misleading or dangerous pitches. But lately, on several platforms, the opposite seems to be happening for a variety of reasons, including a slowdown in the overall digital ad market. Asnumerous deep-pocketed markets have pulled back, and the softer market has led several digital platforms to lower their ad pricing, opportunities have opened up for less demanding advertisers.Advertising experts agree that poor-quality ads appear to be increasing greatly. They point to a variety of potential causes: internal troubles at technology companies, weak content moderation (审核), and high-level advertisers seeking other choices. Then, there’s the economy: A recent survey of 43 multinational companies representing more than $44 billion in advertising spending found that nearly 30 percent planned to cut back on their marketing spending last year.Other factors are also contributing to lower advertising quality. Social media advertising, once only practiced by specialists, is now easily available to anyone. Many of them are avoiding targeted ads—placements intended to reach specific audiences, usually at a higher cost -- in favor of a cheaper spray-and-pray (广撒网式的) approach online, hoping to catch the attention of gullible (容易受骗的) or bored shoppers. Major social media platforms are now like “a mall that used to be good”, Corey Richardson, vice president at a multicultural ad company, says. “But now there’s no longer a mall there —it’s just a place selling anything.”9.What message does the author want to deliver in Portia Kapraun’s story?A.Repeated ads have a strong power of persuasion.B.Social media users often encounter unwanted ads.C.Major brands usually prefer social media advertising.D.An uncertain economy leads to lower levels of consumption.10.What can be inferred about the “less demanding advertisers” mentioned in Paragraph 2?A.They are forced to exit the digital ad market.B.They have benefited from advertising experts.C.They work hard to improve their users’ experience.D.They can now advertise at a more affordable price.11.What is Corey Richardson’s attitude to major social media platforms?A.Negative.B.Unclear.C.Favorable.D.Hopeful 12.Which of the following is a suitable title for the text?A.Where is social media advertising heading?B.What is shaking up the online advertising market?C.Why are you seeing so many bad digital ads now?D.How are targeted ads impacting your-purchase decisions?二、七选五Have you ever had a staring contest? It can be difficult to keep your eyes open for long periods of time because of the natural tendency to blink (眨眼). But why do we need to blink?There are two main reasons. First, blinking clears away dust from the eyes. 13 It might be under the eyelid or something that blew in. Second, blinking lubricates (润滑) the eye-balls. The eyes need a smooth surface for light to properly focus on, so vision becomes clear. Blinking releases a tear film which mostly consists of water, oil and mucus (粘液) to keep the surface of the eyeball smooth. 14 The tear film also supplies oxygen to the eye. Blood doesn’t reach the cornea (角膜), but the tear film directly transfers oxygen to it.Blinking happens naturally. It takes the average person 400 milliseconds to blink. Most people blink somewhere between 10 and 20 times per minute, usually around 15 or 16 times.15For example, you may blink more frequently if there’s something in your eye. Certain conditions can make it feel like there’s something in your eye, which makes you blink more. Some people have habitual involuntary movements that lead them to blink frequently. 16 If you have uncorrected vision problems, you may blink more often because your eyes are naturally trying to correct the unclear vision.If there is damage to the facial nerve, which is responsible for closing the eyelid, a person may blink more slowly or less often. Tiredness and some medications can cause a similar effect. 17 For example, when reading, people tend to blink at the end of a sentence rather than in the middle.A.It prevents the eye from drying out.B.If there’s a foreign body, it helps get rid of it.C.And stress and anxiety can make you blink more, too.D.Blinking more often than needed can give brain extra stress.E.Pink eye and other types of infection can also cause damage on eyes.F.However, there are some circumstances that make people blink more or less often.G.Focusing on something like watching a movie, you may blink less to strengthen your focus.三、完形填空Dr. Karen Sciascia has delivered thousands of babies.

2019-2020学年福建师范大学第二附属中学高三英语上学期期中试题及答案解析第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AThe Fall 2020 Cookbooks Worth Your Time (and Money)Be My GuestFrom Priya Basil, this book is a self-reflection on how food and the act of serving it are used to express love and support. Basil reflects on some of her earliest memories of food and how it affected her upbringing and relationship with her parents. Now a parent herself, she centers food in her book's exploration of that change of identity.EastFrom Guardian columnist Meera Sodha comes a cookbook centered on vegetables. The book features recipes that cover a variety of Asian cuisines. Sodha showcases the diversity of vegetarian cooking with dishes like eggplant larb mushroom bao, Singapore noodles and so much more.I Cook in ColorA follow-up from her first cookbook My Two Souths, Asha Gomez focuses on the rainbow of vegetables to create desserts and cross-cultural dishes that associate cooking traditions of her mother's Keralite kitchen and Gomez's travel experiences.Time to EatIf you're a fan of The Great British Baking Show and Nadiya Hussain's Netflix series, you'll be just as excited for the American release of this book of time-saving tips for home cooks on a budget.

But other birds are wishing up, evolving some seriously impressive tricks to spot the cuckoo eggs.Cuckoos are often know asparasites, meaning that they hide their eggs in the nest of other species. To avoid detection, the cuckoos have evolved so that eggs seem reproduction of those of their preferred targets. If the host bird doesn’t notice the strange egg in its nest, the little cuckoo will actually take the entire nest for itself after it comes out, taking the other eggs on its back and dropping them out of the nest.To avoid this unpleasant fate for their young, the other birds have evolved a few smart ways to spot the fakes, which we’re only now beginning to fully understand. One of the most amazing finds is that birds have an extra colour-sensitive cell in their eyes, which makes them far more sensitive to ultraviolet wavelengths and allows them to see a far greater range of colours than humans can. This allows cautious birds to detect a fake egg which might be exactly the same to our eyes.Fascinatingly, we’re actually able to observe different bird species at very different points in their evolutionary war with the cuckoos. For instance, some cuckoos lay their eggs in the nests of the redstarts. The blue eggs these cuckoos lay are practically alike to those of the redstarts, and yet they are still sometimes rejected. Compare that with cuckoos who target dunnocks. While those birds lay perfectly blue eggs, their cuckoo invaders just lay white eggs with brown irregular shaped spots. And yet dunnocks barely ever seem to notice the obvious trick.Biologists suspect these more easily fooled species like the dunnocks are on the same evolutionary path as the redstarts, but they have a long way to go until they evolve the same levels of suspicion. What’s remarkable isthat the dunnocks fakes are so bad and the redstart ones so good, and yet cuckoos are still more successful with the former than the latter.It speaks to just how thoroughly a species’ behavior can be changed by the pressures of natural selection, or it might just be a bit of strategic cooperation on the part of the dunnocks. Biologists have suggested that these birds are willing to tolerate a parasite every so often because they don’t want to risk accidentally getting rid of one of their own eggs.4. This passage can be most likely found in a ________.A. science surveyB. nature magazineC. zoo advertisementD. travel journal5. What does the underlined word “parasite” in paragraph 2 most probably refer to?A. Animals that work together to raise young.B. Small harmful animals such as worms or mice.C. Animals that can adapt to changing environments.D. Animals which live on or inside other host animals.6. Which of the following is TRUE about the dunnock according to the passage?A. It is colour-blind and therefore cannot identify foreign eggs in the nest.B. It can easily remove cuckoo eggs from the nest because fakes are so bad.C. It is a host bird that is more likely to raise a cuckoo chick than the redstart.D. It is unable to evolve and hence accepts cuckoo eggs that appear in the nest.7. Which of the following can be inferred from the passage?A. Dunnocks may eventually learn to recognise foreign eggs.B. Redstarts seem to be less suspicious compared to dunnocks.C. Cuckoo birds are good at taking responsibility for their own young.D. It is very easy for cuckoos to imitate the colouring of the dunnock’s egg.CThe relationship between humans and the Amazon Rainforest has not always been a harmonious one. However, recent research suggests that the native peoples ofthe Putumayo region helped to protect the rainforest, leaving it unchanged for 5,000 years. Perhaps humans’ coexisting with nature is possible after all.The study, published in PNAS, looked at soil samples in the Putumayo region of the Amazon in Peru to find how humans influenced the land. The researchers found that the trees still growing in the region today have beengrowing there for the last 5,000 years — evidence that the area has not been home to cities and farmland in that time. Traces of charcoal(木炭) found in the, soil, however, indicate that people did live there; they just did so in a way that had minimum influence on their environment.To come to these conclusions the team dug a 0.6-0.9 meter deep column into the ground, taking samples of soilfrom different heights along the column. Back in the lab, samples were carbon- dated to determine their age and then sorted under a microscope to look for microscopic mineral particles, known as phytoliths (植硅体). Phytoliths are essential evidence of plants— they remained in the soil thousands of years after the plant died. So researchers can use them to tell which plants have grown in an area in the past.Over 5,000 years’ worth of samples, no species loss was detected. These findings suggest that contrary to common belief, the Amazon is not untouched by humans, but rather has been protected by them for thousands of years. The management of the rainforest by native peoples appears to have been vital in preserving its biodiversity and will continue to be important in the fight to prevent it from acollapse.As Nigel Pitman, a co-author on the paper, said: “Since this particular forest is still being protected by native peoples, I hope this study reminds us all how important it is to support their work.”8. How did native peoples deal with the rainforest in the region of Putumayo?A. They always destroyed the rainforest.B. They had a side effect on the rainforest.C. They never lived in the area of the forest.D. They had been in harmony with the forest.9. What did the researchers try to find in the Amazon forest in Peru?A. The diversity of the plants in the rainforest.B. The evidence of human influence on the forest.C. The nutrition of the soil samples in the rainforest.D. The survival age of growing trees in the rainforest.10. What does the underlined word “collapse” mean in Paragraph 4?A. Sudden decrease.B. Bad management.C. Poor preservation.D. Over development.11. What can be inferred from Nigel Pitman's words?A. Native peoples should protectthe rainforest.B. We should help protect the Amazon Rainforest.C. More science research should be done on rainforest.D We should make good use of the Amazon Rainforest.DBrian Hamilton's life changed in a prison when he went there with his friend, Reverend Robert J. Harris, who often went to local prisons to do ministry work. During the visit,Hamiltonstarted talking to one of the prisoners and asked what he was going to do when he got out. “He said he was going to get a job,”Hamiltonrecalls. “I thought to myself, wow, that’s going to be difficult with a criminal background.”The conversation madeHamiltonconsider how to help those who came out from prison. Finally in 2008, 16 years after that initial conversation,Hamiltoncreated Inmates to Entrepreneurs, a nonprofit organization that helps people with criminal backgrounds start their own small businesses.At the time,Hamiltonwas building his own company, a software technology company for the banking industry. As his company grew, so didHamilton’s time devoted to giving lessons to prisoners. He averaged three to four courses a month at prisons throughoutNorth Carolina.Eventually,Hamiltondecided to shift his focus to his true passion. In May 2019, he sold his company and focused on helping those who were imprisoned. His online courses will be set next year. “By March 1, 2022, anyone will be able to access the courses, either to become a certificated instructor or to access it for themselves as a prisoner or part of the general population,”Hamiltonexplained.

AI grew up in a house where the TV was seldom turned on and with one wall in my bedroom completely lined with bookshelves. Most of my childhood was spent on books I could get hold of. In fact, I grew up thinking of reading as natural as breathing and books unbelievably powerful in shaping perspectives (观点) by creating worlds we could step into, take part in and live in.With this unshakable belief, I, at fourteen, decided to become a writer. Here too, reading became useful. Every writer starts off knowing that he has something to say, but being unable to find the right ways to say it. He has to find his own voice by reading widely and discovering which parts of the writers he agrees or disagrees with, or agrees with so strongly that it reshapes his own world. He cannot write without loving to read, because only through reading other people’s writing can one discover what works, what doesn’t and, in the end, togeth er with lots of practice, what voice he has.Now I am in college, and have come to realize how important it is to read fiction (小说). As a law student, my reading is in fact limited to subject matter—the volume (量) of what I have to read for classes every week means there is little time to read anything else. Such reading made it clearer to me that I live in a very small part in this great place called life. Reading fiction reminds me that there is life beyond my own. It allows me to travel across the high seas and along the Silk Road, all from the comfort of my own armchair, to experience, though secondhand, exciting experiences that I wouldn’t necessarily be able to have in my lifetime.21. What can be inferred about the author as a child?A. He never watched TV.B. He read what he had to.C. He considered reading part of his life.D. He found reading unbelievable.22. The underlined word "voice" in the second paragraph most probably means “”.A. an ideaB. a way of writingC. a sound qualityD. a world to write about23. What effect does reading have on the author?A. It helps him to realize his dream.B. It increases his interest in worldwide travel.C. It makes his college life more interesting.D. It opens up a wider world for him.24. Which of the following can be the best title of this text?A. What do I read?B. How do I read?C. Why do I read?D. When do I read?BMove over, helicopter parents. “Snowplow (扫雪机) parents” are the newest reflection of an intensive (强化的) parenting style that can include parents bookingtheir adult children haircuts, texting their college kids to wake them up so they don’t sleep through a t est, and even calling their kids’ bosses.Helicopter parenting, the practice of wandering anxiously near one’s children, monitoring their every activity, is so 20th century. Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children’s path to success, so they don’t have to suffer failure, frustration (挫折) or lose opportunities.It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.Rich parents may have more time and money to make sure their children don’t ever meet with failure, but it’s not only rich par ents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.Yes, it’s a parent’s job to support the children, and to use their adult wisdom to prepare for the fut ure when their children aren’t mature enough to do so. That’s why parents hide certain toys from babies to avoid getting angry or take away a teenager’s car keys until he finishes his college applications.But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?“Solving problems, taking risks and overcoming frustration are key life skills,” many child development experts say, “and if parents don’t let their childr en experience failure, the children don’t learn them.”25. What do we know about snowplow parenting?A. It appeared before helicopter parenting.B. It costs parents less than helicopter parenting.C. It provides more than enough services for children.D. It was very common in the 20th century.26. What does the fourth paragraph mainly say about snowplow parenting?A. Its cost.B. Its popularity.C. Its benefits.D. Its ending time.27. Why does the author mention parents’ taking away car keys?A. To show it’s correct to help children when necessary.B. To advise teenagers not to treat their cars as toys.C. To advise parents not to buy cars for their teenagers.D. To show teenagers are no better than babies.28. What’s the possible result of sn owplow parenting according to the experts?A. Children meeting no problems after growing up.B. Children mastering more key life skills than parents.C. Children gaining great success in every aspect of life.D. Children lacking problem-solving ability in reality.CIf you ask most people what water tastes like, they’ll probably tell you that water has no taste and they may give you a funny look. But if you were a fruit fly, asking another fruit fly, that question might have a different answer.To a fruit fly, water has a taste. Scientists want to know how the fruit fly knows water because this information may help in learning how other animals — or even individual cells —manage to use water in the right way. Water is important to life, but too much or too little can be deadly to a living creature. So by understanding how the fruit fly tastes water, researchers may learn more about other living things.According to the new study, a protein (蛋白质) called PPK28 makes it possible for a fly to taste water. Proteins build cells and tissues, fight disease and carry messages between cells. It’s not surprising that a protein is responsible for the fruit fly’s ability to taste water.The PPK28 protein is part of a larger family of similar proteins. One of these related proteins is used by mammals (哺乳动物) (including humans) to taste salt. Scientists have not found a protein that enables humans to “taste” water.In the experiment, Cameron and his team compared normal fruit flies with fruitflies whose taste cells had been disabled. The fruit flies were given a special chemical that would glow (发光) when the fly used the PPK28 protein. Then the scientists led the flies to water. When the normal flies tasted the water, the PPK28 protein lit up — showing that it was in use.The fruit fly in particular is so interesting that some scientists are hard at work creating a complete map of the fruit fly brain. This map will show all of a fly’s neurons and help scientists understand how the neurons (神经元) work together.29. How do most people feel when asked the taste of water?A. Disagreeable.B. Frightened.C. Disappointed.D. Strange.30. Why do scientists want to know how the fruit fly knows water?A. To know more about other creatures.B. To decrease the number of the fruit fly.C. To manage to use water correctly.D. To describe the taste of water.31. What do we know about the PPK28 protein?A. It enables the fruit fly to taste water.B. The fruit fly can’t live without it.C. It can make humans taste salt.D. The fruit fly uses it to avoid illnesses.32. What will the scientists continue to work at?A. Creating maps of human brains.B. Telling more information about cells.C. Studying the fruit fly’s neuron systems.D. Making the PPK28 protein.第二节 (共5小题; 每小题2分, 共10 分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。
