＝x2y2，所以x2+y2+2xy＝x2y2，即（x+y）2＝x2y2，而x、y均为正数，故x+y＝xy，可得．对于A，，两边平方得x2y2≥4xy，可得xy≥4，故A错误；对于B，由A的计算可知x+y＝xy≥4，当且仅当x＝y＝2时取到等号，故B正确；对于C，x2+y2＝x2y2﹣2xy＝（xy﹣1）2+1≥32﹣1＝8，当且仅当x＝y＝2时取到等号，故C正确；对于D，，当且仅当x＝2y，即时取到等号，故D正确．故选：BCD．【点评】本题主要考查了不等式的性质、基本不等式及其应用等知识，考查了计算能力、逻辑推理能力，属于中档题．三、填空题（共4小题，每小题5分，满分20分）13．（5分）已知函数，则函数f（x）的定义域为[﹣2，1]．【分析】根据函数的解析式，列出使函数解析式有意义的不等式组，求出解集即可．【解答】解：函数∴﹣x2﹣x+2⩾0，解得﹣2⩽x⩽1．∴函数的定义域为[﹣2，1]．故答案为：[﹣2，1]．【点评】本题主要考查函数定义域的求解，属于基础题．14．（5分）已知函数f

广东省部分名校2023-2024学年高一上学期期中联合考试英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解I’m a. . . digital nativeThe online world is a big part of my life. I’m a “digital native” — I’ve been using the computer since I was a kid.I do a wide range of things online. Besides doing all my schoolwork, I chat with my friends, watch films and read the daily news and other interesting articles. I also shop for various things online, such as books, computer hardware, and other necessities. It’s so convenient to be able to compare the quality and prices from different online shops before I buy. I also play computer games from time to time and I even play tennis on my television screen in my living room!My parents are worried that I may become an “Internet addict”. They think I’m playing computer games all the time, and that I chat too much with online friends. According to them, there is a danger that I may not be able to tell whether these friends are real friends. My mum keeps telling me to go out with my school friends instead. Maybe she’s right. It’s important to meet friends in person from time to time, not just on social media. Actually, I do know I need to drag myself away from the online world sometimes, especially because the real life can be just as interesting.1．What does the underlined phrase “digital native” mean?A．Someone skilled at study.B．Someone who lives in a city.C．Someone who runs an online shop.D．Someone very familiar with the online world.2．How does the writer probably benefit from doing things online?A．He sells various things online.B．He can save money when shopping.C．He can post his interesting articles.D．He can make better friends.3．What are the writer’s parents most worried about?A．His schoolwork.B．His social life.C．His health.D．His diet.The world will become a better place when we realize that everyone can have bad daysand that we care enough and take actions. Rachel Harder, a fourth-grade teacher from Kansas, recognized this, and she found an amazing way to help out both her students and their families.A few years ago, Rachel attended a trauma (精神创伤) conference. She learned that some police stations worked together with schools. They could let teachers know when their students need help, patience or extra care.A year after the conference, Rachel had a student with autism who frequently had difficult days. To support the student, Rachel told the student’s mom to simply text her “Handle with Care” to let her know when the student was experiencing difficult time. “When she would text me, I knew that her daughter needed some extra time and a quiet place to get help, not going to the playground for morning announcements (通告) , so that the rest of her daughter’s day went well,” Rachel said.The simple method was such a success that Rachel decided to send all of her students home with a note for their parents. It explained what the “Handle with Care” system was and how they could make use of it. In no time, the parents began to show their appreciation for Rachel’s unbelievable act of kindness.But Rachel’s kindness didn’t end with her class. News spread of the amazing system, and teachers across the country began giving it a shot in their own class. Printed materials could be found on the school website, and the feedback (反馈) has been extremely positive! 4．How did Rachel support the student with autism?A．By giving more time and a quiet place.B．By taking the student to the playground.C．By sending text messages to her mother.D．By making sure she has a good rest. 5．What happened after Rachel sent notes home to all the parents?A．The parents expressed their thanks.B．Rachel showed kindness only to her class.C．Teachers nationwide stopped using the system.D．Parents gave comments on printed material.6．What is the text mainly about?A．Rachel Harder’s creative teaching methods.B．The importance of teachers’ work with police.C．A way to support students’ emotional health.D．The impact of the “Handle with Care” system.One characteristic (特征) of shyness is to feel frightened and nervous in new social situations or when being the center of attention. Whether shyness is part of your child’s personality or just something they feel when they are in front of a group of strangers, it is a common experience, according to a study.To look at shyness, researchers brought 152 children aged 7-8 into a lab and told them they would give a speech which would be filmed and shown to other children. The study showed that about 40% of the children showed a level of stress when giving the speech. About 25% of the children were not thought to be shy by their parents, but in fact showed a level of social stress from giving the speech. This finding proves the fact that shyness is more common than we think.For children at this age, shyness may be a normal experience when they face a speech task. For a smaller group of shy children, however, being the center of attention may be stressful at different times and environments.Shy people aren’t always valued by society like outgoing ones but that doesn’t mean there is something wrong. Everyone can feel shy at times depending on the environment. And those who are shy often have happy social lives—they just aren’t likely to be the liveliest (最活泼的) people in a crowded room.Although shyness itself may not be a problem, parents should pay attention to signs of stress in their shy children. Importantly, however, we know that not all shy children are the same, and that many shy children grow up to be happy adults7．What can we learn about shyness from paragraph 1?A．Shyness is something we are born with.B．Shyness is not unusual.C．Shyness is the center of attention.D．Shyness means not talking to others. 8．What did researchers find during the study?A．Some kids got stressed while giving speeches.B．Few kids like to give a speech to others.C．Some kids appear more shy with their parents.D．Some kids are stressed when being separated.9．What does the author advise parents to do when facing shy children?A．Bring them to crowded spaces.B．Encourage them to be braver.C．Watch for signs of pressure.D．Try to give them more time alone.10．What can be the best title for the text?A．When are people shy?B．Ways of beating shynessC．Why is shyness a bad thing?D．A discovery about shyness二、其他11．将下列几个部分（A、B、C、D和E）按题号排序，构成一个符合逻辑的完整语篇。

秋风桐槐说项羽梁衡①这里属于江苏省宿迁市。

我原以为故里者只是一座古朴的草房，或农家小院，不想这项羽故里竟是一座新修的旅游城，而城中真正与项羽有关的旧物也只有两棵树：一棵青桐，一棵古槐。

斯人远去，就只有来凭吊这两棵树了。

②那棵青桐，树上特地挂了牌，名“项里桐”。

据说，项羽诞生后，家人将他的胞衣(胎盘)埋于此树下，这桐树就特殊茂密，青枝绿叶，直冲云天。

在中国神话中梧桐是凤凰的栖身之地，有桐有凤的人家贵不行言，项羽在此树下诞生盖有天意。

梧桐之东不远处，有一棵巨大的中国槐，说是项羽手植。

两千年的风雨，手植槐修成了黄河槐；黄河槐又炼成了雷公槐。

这摄取了天地之精、大河之灵的古槐，日修月炼，水淹不没，沙淤不死，雷劈不倒，壮哉项羽！③项羽的家乡在苏北平原，两千年来战火多数，文物留存极少，而其故里始终未被遗忘，直到现在这个旅游城。

城内遍置各种与项羽有关的游乐设施，其中有一种可在架子上翻转的木牌，正面是项羽、虞姬等各种画像，翻过来就是一条条因项羽而生的成语。

如：破釜沉舟、取而代之、一决雌雄、所向无敌、拔山扛鼎、分我杯羹……现在我们常用到的成语总共也就一千多条，项羽一人就占百条。

要知道他才活了三十一岁，政治、军事生涯也只有五年。

后人多观赏他的武功，倒忽视了他的文化贡献。

④项羽是个失败的英雄，失败缘于他人性的弱点。

刚烈坚毅又优柔寡断，欲雄霸天下又留恋家乡；他少不读书，临终之时却作“力拔山兮气盖世”，感天动地、流传千古；他杀人如麻，却爱得缠绵，在身陷重围、生死攸关之际还与虞姬弹剑而歌。

他身上有巨大的悲剧之美，因此他是艺术境界中的人物，是艺术创作的好原型。

⑤项羽是民间筛选出来的体现了平民价值观和生活旨趣的人物，人们宠爱他的英勇刚烈、纯朴真实，就如宠爱关羽的忠义一样。

历史上的“两羽”一勇一忠，成了中国人的偶像，是与岳飞的精忠报国、文天祥的青史丹心并存的两个价值体系。

Get chewing: can a wellness rebrand make Americans buy gum again?When was the last time you saw someone chewing gum? 1998, maybe? 2007? Chances are, it probably wasn’t recently. Like high heels and affordable housing, chewing gum appears to be going 42Gum’s popularity has been fading globally thanks to increased competition from products like breath mints and mobile phones distracting us from impulse purchases while shopping. The pandemic, moreover,43 ·accelerated gum’s decline.Even after people 44 from lockdown, sales didn’t recover. Gum sales worldwide in 2023 were 10% below 2018 figures. In the US, the drop has been particularly pronounced: last year 1.2 billion units of gum were sold in the US, 32% fewer than in 2018.However, chewing gum, in various forms, is one of the oldest habits there is. Stone age teenagers were chewing birch bar k tar possibly for pleasure, medicinal purposes, or to use it as a glue. Gum has also been loaded with cultural meaning and the subject of various 45 panics. Some people believe it is a marker of the bad kidsor a habit of the lower class.Despite a certain amount of social stigma（污名）attached to gum, it has - until relatively recently -been a wildly successful product. That’s thanks to William Wrigley Jr, who was a marketing and advertising genius. Wrigley always 46 to find a way to make gum relevant and insert it into consumer culture. For example, Wrigley advertised the idea that chewing gum was a health aid that would help digestion and would relieve stress.This year the Wrigley brand’s owner —Mars— came out with an ad campaign it hopes will revive gum’s47 by positioning it as an almost instant stress reliever. Linking gum with wellness worked in the 1910s, but is it going to work now? Alex Hayes at the food consultancy is 48 optimistic. “The global well ness market is estimated to be worth more than $1.5 trillion, so it’s no surprise that Mars wants a piece of the pie,” Hayes says. “We’ve seen the success of categories such as tea promoting their products via functional 49 and messaging-teas for good sleep, mental clarity, stress relief, etc. So it comes as no surprise that Mars is risking the same 50 .” But he also notes, customers are increasingly worried about processed foods and are eager to move away from artificial 51 . There’s still ongoing discussion on just how effective repositioning chewable plastic as a health supplement is going to be.Ⅲ．Reading ComprehensionSection A ClozeDirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.It’s safe to say Jeremy Scott is having a lucky year. In March while working as a chauffeur, he told his boss about his plans to set up a driving business. By the end of the journey, Scott’s boss had offered to 52 his idea-a starting capital along with the gift of a £110,000 limousine（豪车）to kick start the business.Of course, there’s an element of luck to everyone’s career. Whether you’re a chief executive or an artist — your 53 won’t be based on hard work alone. For example, the place you were born 54 your education. It determines whether you learn to read, write or complete qualifications, which 55 limits your career choices.Many people believe success is down to talent and hard work, but “this is because most people underestimate the role of 56 ”, says psychologist Dr Elizabeth Nutt Williams. “We do a lot of work to prepare for our careers-education, training, taking advantage of mentoring-all of which tend to be in our control.” People don’t like to acknowledge the role of luck in their work, as it 57 this feeling of being in control, adds Williams.Everyone remembers working hard, so people are more likely to overestimate how much of their success is down to diligence than something much more 58 like luck.The reality of success （at least in terms of 59 ）is less clear cut. In the UK, studies show where you are born is likely to determine how much you earn.2017 research found that there is a “class pay gap’’, where professional employers from 60 backgrounds are paid almost £7,000 less a year — despite having the same role, education and experience as colleagues from more privileged families. 61 , black graduates earn up to 23% less per hour than white university leavers, whereas woman in the UK earn 14% less on average than men.Socio-economic status also plays a big role in the 62 you enter. A recent study by the Debrett’s Foundation found seven in every 10 young people aged 16-25 use 63 to get their first job. While research hasshown that less able, richer children are 35% more likely to become high earners than their brighter. poorer peers.The truth is: chance and coincidences 64 our careers more than we like to think. Realizing that parts of your career are out of your control sounds 65 , but being grateful for the role of luck in your career can actually make you more fortunate.This is because when you acknowledge the role of luck in your work, you become prepared to take advantage of more fortunate moments. “Chance events occur·but it is all about the individual’s 66 to see those events as possibilities and their willingness to take a risk,” says Williams.52．A．challenge B．adopt C．finance D．reject 53．A．performances B．accomplishments C．assessments D．outcomes 54．A．accounts for B．applies to C．makes up for D．depends on 55．A．in reward B．after all C．in turn D．by nature 56．A．chance B．accident C．education D．diligence 57．A．emphasizes B．overlooks C．maintains D．weakens 58．A．manageable B．vital C．slippery D．minor 59．A．reputation B．income C．education D．occupation 60．A．wealthier B．poorer C．unique D．diverse 61．A．Nevertheless B．Contrarily C．Consequently D．Similarly 62．A．profession B．circle C．community D．university 63．A．certificates B．online platforms C．career fairs D．family connections 64．A．contribute to B．result from C．add to D．hold back 65．A．inspiring B．encouraging C．appealing D．discouraging 66．A．reluctance B．eagerness C．readiness D．resolutionSection B Passages（A）When you think about coffee alternatives, garlic is probably one of the last things that comes to mind, but that is exactly the ingredient that one Japanese inventor used to create a drink that looks and tastes like coffee.74-year-old Yokitomo Shimotai, a coffee shop owner in Aomori Prefecture, Japan, claims that his unique “garlic coffee” is the result of a cooking blunder he made over 30 years ago, when he burned a steak and garlic while waiting tables at the same time. Intrigued by the burnt garlic’s smell, he mashed it up with a spoon and mixed it with hot water. The resulting drink looked and tasted a lot like coffee. Making a mental note of his discovery, Yokimoto carried on with his job and only started researching garlic coffee again after he retired.Committed to turning his weird drink into a commercial product, Yokitomo Shimotai spent years optimizing the formula, and about five years ago, he finally achieved a result he was satisfied with. To make his dissolvable garlic grounds, he roasts the cloves（蒜瓣）in an electric oven, and after they’ve cooled off, smashes them into fine particles and packs them in dripbags.“My drink is probably the world’s first of its kind,” the garlic coffee inventor told Kyodo News. “It contains no caffeine so it’s good for those who would like to drink coffee at night or pregnant women.”“The bitterness of burned garlic apparently helps create the coffee-like flavor,” Shimotai adds. He claims that,although his garlic coffee does give off an aroma of roasted garlic, it doesn’t cause bad breath, because the garlic is thoroughly cooked. And if you can get past the smell, the drink apparently does taste a lot like actual coffee. If decaf isn’t good enough for you, and you’re in the mood for something new, you can try Yokitomo Shimotai’s garlic coffee at his shop, in the city of Ninohc, lwate Prefecture, or buy your own dripbags for just 324 yen （$2.8）.67．Which word is the closest in meaning to the underlined word “blunder” in the second paragraph?A mistake B．show C．mixture D．brand68．Who is NOT suitable to drink garlic coffee?A．A student having trouble with sleep B．A woman bearing a baby.C．A cleaner working on a day shift.D．A young lady sick of garlic.69．Which of the following is NOT characteristic of garlic coffee?A．It is caffeine-free.B．Garlic powder dissolves in waterC．The burnt garlic create s bitterness.D．It is an improvement on a garlic dish. 70．Which of the following can be used to describe Yokitomo Shimotai?A．Venturous and greedy B．Innovative and perseverantC．Hardworking and cautious D．Observant and helpful（B）71．By “how they stacked up” in paragraph 1, the author probably means “how they ______.”A．make sense to manufacturers B．get stuck in storesC are compared with each other D．are piled up together72．Which of the following devices favourably reacts to users?A．Dreampad pillow B．Eight sleep trackerC．Smart Nora Wireless Snoring Solution D．Nightingale Smart Home Sleep System 73．Which of the following statements is true according to the passage?A．The Eight keeps the entire bed at the same temperature.B．The Nightinga, is an economical but perfect device.C．Soft music is applied to all these four devices.D．One in three people suffer from sleep problem.（C）One way to divide up the world is between people who like to explore new possibilities and those who stick to the tried and true. In fact, the tension between betting on a sure thing and taking a chance that something unexpected and wonderful might happen troubles human and nonhuman animals alike.Take songbirds, for example. The half-dozen finches（雀）resting at my desk feeder all summer know exactly what they’ll find there: black sunflower seed, and lots of it. Meanwhile, the warblers（莺）exploring the woods nearby don’t depend on this predictable food source in fine weather. As food hunters, they enjoy less exposure to predators and, as a bonus, the chance to meet the perfect mate flying from tree to tree.This “explore-exploit” trade-off（权衡）has prompted scores of lab studies, computer simulations and algorithms（算法）, trying to determine which strategy brings in the greatest reward. Now a new study of human behavior in the real world, published last month in the journal Nature Communications, shows that in good times, there isn’t much of a difference between pursuing novelty and sticking to the status quo（原状）. When the going gets tough. however, explorers are the winners.The new study, led by Shay O’Farrell and James Sanchirico, both of the University of California, Davis, along with Orr Spiegel of Tel Aviv University, examined the routes and results of nearly 2,500 commercial fishing trips in the Gulf of Mexico over a period of 2.5 years. The study focused on “bottom longline” fishing, a system where hundreds of lines are attached to a horizontal bar that is then lowered to reach the sea bed. Dr. O’Farrell explained the procedure this way: Go to a location and put the line down. Stay for a few hours. The lines are a mile long and have a buoy （浮标）at either end. When they pull that up, they assess the catch, and then decide if they will stay or move on to a different spot.Over two years of collecting data under various climate conditions, the researchers discovered that thefishermen were fairly consistent. “The exploiters would go to a smaller set of locations over and over, and go with what they know,” Dr. O’Farrell said. The explorers would constantly try a wider range; they’d sample new places.In the long run, there wasn’t a huge difference in payoffs between the two groups, perhaps due to the sharing information between fishing crews, said Dr. O’Farrell. But in challenging times, the study’s message was clear: “You can try new things in the face of uncertainty.”74．The author takes the songbird as an example to indicate that ______.A．like birds, humans tend to be satisfied with the predictableB．some birds are used to looking for food instead of being fedC．there exist the conservative and the adventurous like humansD．birds choose different ways to look for food in different weather75．According to the third paragraph, people who mastered “explore-exploit” trade-off ______.A．will choose either to pursue novelty or keep the status quoB．are ready to risk in time of difficultyC．will be tough in good times and bad timesD．will grow to be experts in lab studies76．Which can be inferred from the new study led by Shay O’Farrell and James Sanchirico?A．The two groups react to the unexpected differently.B．The “explore-exploit” trade-off helps scientific research a lot.C．The exploiters are used to fishing based solely on their experience.D．The explorers tend to achieve more than the exploiters in the long run.77．Which of the following can be the best title for passage?A．How the Exploiter differs from the Explorer B．How to Become a Productive Fisherman C．What is “Explore-Exploit” Trade-off D．When to take risks mattersSection CDirections: Read the following passage. Fill in each blank with a proper sentence given in the Each sentence can be used only once. Note that there are two more sentences than you need.The Maya loved cacao so much that they used the beans as currency. They also believed it is good for you—which many people still say today about cacao’s most famous byproduct, chocolate. 78 . While some have suggested that less than an ounce of dark chocolate might improve heart health, much of the research doesn’t involve eating actual chocolate but rather its components — flavanol, especially.79 . In a clinical trial of 21,000 adults, they found that the half of the group that took500mg of. cocoa flavanol supplements daily had a significantly lower risk of death from cardiovascular disease than those who had taken a placebo（安慰剂）.Flavanols may also boost insulin sensitivity, according to some studies, which might be helpful in reducing the risk of type 2 diabetes（糖尿病）. 80 . Those at risk of diabetes might be wise to choose a cacao-inspired supplement instead of eating chocolate—and the sugar it contains. Other research suggests that the flavanols found in cacao （also present in fruits, vegetables, and tea）could slow cognitive decline during aging, or even boost brain performance by improving blood flow to the cerebral cortex.What these findings mean for chocolate is limited, however. Participants would have had to eat multiple fat and sugar filled chocolate bars a day to source 500mg of flavanols. 81 . So understanding why certain types of chocolate are healthier than the rest is the focus of further research.Ⅳ．Fill in the BlanksHow sneaker culture took over the worldSneakers have come a long way from when they were first invented in 1860s England for the upper-class playing croquet（槌球）and tennis.Long worn for function 82 82 fashion, today sneakers have become an entire culture—both a form of self-expression and a high art found in museum exhibits and designer auction houses.83 transformed sneaker culture into a true phenomenon was the 1985 release of Nike’s Air Jordan 1s. In 1984, Michael Jordan was a talented rookie who had yet to play in a professional game. 84 that, Nike saw Jordan as the future of their brand, signing him to a five-year, $2.5 million endorsement（代言）deal. 85 Jordan matured into one of the greatest basketball players of all time, the sneaker’s popularity skyrocketed.Meanwhile, another cultural shift 86 （take）place with casual Fridays introduced in white-collar businesses. It was when men were allowed to put aside their suits and wear something one day a week that showed people who they really were.As sneakers became increasingly desired, footwear companies turned to 87 （generate）even more publicity by collaborating with celebrities and luxury brands, as well as releasing small batches of limited-edition shoes with eye-pop ping designs.Celebrities also started their collaborations with sneaker brands, which helped target a whole new demographic of people to experience sneaker culture. It was a blending of high and low fashion, 88 the shoe industry has never really seen before. A pair that Jordan wore in his legendary final NBA season 89 （sell ）even for $2.2 mllion, making them the most expensive sneakers ever to appear at auction.By the mid-2010s, speakers 90 （become）solid gold status symbols. Wearing rare and cool sneakers became an expression of one’s social status. But not until recently, sneakers are finally getting their due as part of our cultural heritage—and particularly how Black culture has shaped that heritage. It took decades for the sneaker industry to recognize that 91 these Black athletes or artists that championed their products there would be no sneaker culture.Ⅴ．Translations92．结果看来这项传统的确值得传承给我们的后代。

We would watch game shows in the living room. Our favorite was The Price Is Right. We would call out our answers along with the contestants.When I got older and started going to school，we couldn’t watch our game shows regularly. That was okay with me，though，because the one thing I liked better than watching game shows with my grandmother was helping her bake cakes. Watching her in the kitchen was amazing：she never seemed to need the recipes（食谱）but everything she made tasted delicious.At first I would just sit in the kitchen and watch，even though I didn’t understand what she was doing. As I got older，she let me help with the easy parts，such as measuring the sugar. The day she let me separate the eggs，I felt like I had found complete pleasure.At last，my parents decided that I could take care of myself，and my grandmother stopped coming over every day. The love of baking，however，stayed with me. I started baking by myself，and even if the cookies ended up burnt sometimes，more often they turned out pretty well. I tried out new recipes，and whenever I got to a thorny part，I would call my grandmother for advice. Sometimes I would call her just to talk too. I felt like I could talk to her about anything.My grandmother passed away ten years ago，but I still think of her every day. Last week，I found a recipe book she made for me. It included her recipes for brownies，cookies，and my favorite，lemon pie. As I looked through the pages，I thought I could hear her voice. She was the one who taught me not just about baking，but about life.24．The passage is mainly developed by .A．analyzing causes B．making comparisonsC．following the time order D．examining differences25．While helping her grandmother bake，the author .A．found it interesting B．turned out to be a troublemakerC．hoped to make a living by baking D．regretted missing the game shows 26．What does the underlined word “thorny” in Paragraph 4 most probably mean?A．Basic.B．Common.C．Special.D．Difficult.27．What’s the author’s purpose in writing this passage?A．To describe her childhood memories.B．To show her good baking skills.C．To remember her grandmother.D．To talk about her happy family life.Like many people over the past few years, I have found myself turning to audiobooks as my main means of reading literature. I find it far more comfortable to “read with my ears” while my eyes are resting. My consumption of new books has doubled as a result--but a recent paper makes me wonder if this will come at the price of my comprehension.The study comes from Boaz Keysar and Janet Geipel, both at the University of Chicago, and it draws from the “dual process model” of mental processing. According to this-view, we have two ways of assessing information. System 1 is intuitive (直觉的),relying on natural ability and feeling. It is quick, but likely exposed to misinformation. System 2 is analytical involving the use of logic reasoning. It is mentally demanding. When it is engaged, we think our way through the material step by step. For decades, psychologists have designed various tests to determine which of these two systems a person is using. As one example, consider the/ following question: How many animals of each kind did Moses take on the Ark (方舟)? If you answered two, you were probably only considering the core of the question, which is System 1 thinking. To get to the right answer-zero, you need to think more carefully about the wording, which would allow you to remember it was Noah who built the Ark, not Moses. That is the kind of analytical process.Keysar and Geipel’s brilliant idea was to investigate whether the sensory form-seeing vs. hearing-of the information would make a difference. They found that it did: when answering thesekinds of simple questions, participants were more likely to make errors when the sentences were spoken out loud, rather than written.A greater reliance on our feelings could be a problem if we are consuming information that needs logical study. For this reason. I will return to reading non-fiction with my eyes rather than my ears. But I won’t stop listening to novels. I am quite happy to go with the flow of my emotions while my critical mind takes a break.28．What does the author think of listening to audiobooks?A．It is economical.B．It is demanding.C．It is time-consuming.D．It is relaxing.29．Which of the following best describes System 2 model?A．Fairly reliable.B．Fully automatic.C．Question-centered.D．Emotion-involved.30．Why is the Ark mentioned in Paragraph 3?A．To present a fact.B．To illustrate a view.C．To introduce a topic.D．To draw a conclusion.31．What does the author intend to tell us?A．Listening to books comes at a price.B．Reading non-fiction books benefits.C．Critical thinking is a must in reading.D．Ways of processing information differ.About 12% of the total global energy demand comes from heating and cooling homes and businesses. A new study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this section by 40% in the US. The approach is called A TES, short for aquifer thermal energy storage (含水层热能储存).“We need storage to absorb energy from the sun and wind. It’s crucial to creating affordable, reliable, and deeply environmental-friendly electricity systems. Most people are interested in batteries and other kinds of electrical storage. But we were wondering whether there was any opportunity to use geothermal (地热的) energy storage,” said first author A．T.D Perera. “With ATES, energy can be stored for a long period of time, without adding an additional burden to thegrid (输电网).”ATES is a pleasantly simple concept that takes advantage of the heat-absorbing property of water and the natural geological features of the planet. You simply pull existing underground water up and heat it at the surface in the summer with environmental heat or energy. Then you send it back down. It stays fairly hot because the Earth is a good insulator (绝热体).“Unlike above-ground tank-based water or ice storage systems, ATES will not need space. It’s also more efficient and can support larger communities in cooling or heating than traditional geothermal heat pump systems that rely on heat moving with the underground soil,” added co-author Hong Tianzhen.A major beneft of ATES is that it will become more efficient as weather becomes more extreme in the coming years due to climate change. The hotter summers and severer winters could increase the amount of free thermal energy that can be stored with ATES. “It’s very much a realistic thing to do and this work is really about showing its value,” said Perera. “This technology is ready to go, so to speak. We just need to do it.”32．What do we know about ATES?A．It is technologically demanding.B．It is aimed at replacing natural energy.C．It mainly relies on batteries to function.D．It helps achieve an environmentally friendly society33．How does Hong Tianzhen explain ATES’s advantages?A．By giving examples.B．By discussing results.C．By making comparisons.D．By analyzing principles.34．Which will affect ATES’s efficiency most?A．Temperature variations.B．Insulated materials.C．The duration of storage.D．The category of energy.35．What can be the best title for the text?A．A Turning Point in Energy UsageB．A Solution to Green Cooling and HeatingC．A Transformation in the US Electricity SystemD．A Discovery About Geothermal Energy StorageIt’s no surprise that there’s a link between exercise and mental health. But scientists have now made it official: research has found a direct connection between movement and mood. Why does exercise hold so many benefits for our mental health? 36 .When our muscles tighten, chains of amino acids (氨基酸) called myokines (肌细胞因子) are released into the bloodstream. 37 . This communication increases adaptation to stress, reduces symptoms of anxiety and has a direct effect on depression.A recent study published in the British Journal of Sports Medicine showed that treatment for depression can be much more effective when physical activity is added to the usual care.38 . “While exercise is not a substitute for professional mental health treatment, physical activity can complement and enhance the effects of the treatment,” says lead researcher Ben Singh, a research fellow at the University of South Australia. He says regular exercise in a group setting can boost self-esteem and decrease feelings of isolation and loneliness.Exercise helps build key connections between the networks within the brain, too.39 . Studies have shown that physical activity stimulates creativity, sharpens judgement skills and improves mental energy. It can also help to slow age-related cognitive decline, possibly even slowing the pace of developing Alzheimer’s disease.40 . In this way you’ll keep going back to them. Experts suggest that you aim for a minimum of 10 to 30 minutes, three to five days each week. Getting sweaty is good for your body and mind.A．It can improve overall cognitive performanceB．They help your muscles and organs communicateC．The answer, studies say, lies in our brain chemistryD．Here are the suggestions that you are supposed to pay attention toE．It is amazing to consider how moving our bodies can affect our mindsF．To get the biggest health boost, the key is to be engaged in sports you enjoy G．Participants found benefits after 12 weeks of exercising for 30 to 60 minutes a day三、完形填空Isabella Springmuhl Tejada is one of the first professional fashion designers with Down Syndrome (唐氏综合征).Her path to success wasn’t 41 .Although she showed her 42 .for design in childhood, when she would spend hours designing paper dresses for her dolls, she was 43 from several fashion schools due to her disease.
