C.Annoying background noise doesn’t exist in the hearing aid.D.It’s not easy for others to notice a patient wearing the hearing aid.BIn1880,the traveller and journalist Lafcadio Hearn was living in New Orleans and writing for a couple of local papers, Daily City Item and Times-Democrat.Hearn sensed that New Orleans exists in a state of insidious disintegration(蜕变)—“crumbling into ashes”—thanks to its dangerous geography and its“frauds and maladministrations.”And yet,Hearn wrote to a friend,“It is better to live here in sackcloth and ashes than to own the whole state of Ohio.”New Orleanians have always resembled New Yorkers;they tend to share the sense that to live anywhere else would lead inevitably to a stupid and pitiable existence beyond the bounds of understanding.In part,the spirit of New Orleans is rooted in the city’s below-sea-level unsteadiness,the condition of looking out—and even up—at the water all around you,the knowledge that water saturates(浸透)the ground you stand on.Katrina,the fierce hurricane that destroyed the Gulf Coast on August29,2005,tested the self-possession of every citizen who survived it.More than eighteen hundred people did not survive it,and hundreds of thousands lost their homes.The storm and the terrible flooding that followed—a natural disaster worsened by a range of man-made disasters—revealed much that had been fragile,or rotten,in Hearn’s time and grew worse with every decade:shabby civil engineering;corrupt and inefficient government institutions;and it turned out that an Administration in Washington witnessed for days a city drowning—a largely black city drowning—and reacted with annoying indifference.And yet,in the face of abandonment—in hospitals, on rooftops,on highway overpasses—the residents of New Orleans behaved with resilience(不折不挠).Rebecca Solnit, an acute observer of Katrina and its aftermath,has written,“The belief that a Hobbesian war of all-against-all had broken loose justified treating the place as a crime zone or even an unfriendly country rather than a place in which grandmothers and children were trapped in frightful conditions,desperately in need of food,water,shelter and medical attention.”Alec Soth,a photographer who lives in Minneapolis and travels the Midwest and the South with the energy of a latter-day Walker Evans,did not join the artists who came to New Orleans a decade ago to capture what he calls the“eye candy of rot and ruin.”Instead,he waited,preferring to capture the city of water ten years later,a city in a state of both persistent suffering and persistent renewal.Soth shows us the upsetting image of a freestanding column—all that is left of a house in the hard-hit Lower Ninth Ward—but he moves toward a vision of promise,a lonely figure at his leisure,staring into the waters of today’s New Orleans.58.New Orleanians are similar to New Yorkers in that______.A.they refuse to leave their homelandB.they exist in insidious disintegrationC.they possess dangerous geographyD.they have a sense of boring existence59.What can we know from the hurricane Katrina and its damaging consequences?A.A range of man-made disasters led to the fierce hurricane.B.The hurricane happened following a terrible flooding.C.The American government failed to provide help and support.D.The residents of New Orleans have a deep hatred for governors.60.Why did Alec Soth refuse to join other artists to take photos of New Orleans a decade ago?A.He also treated New Orleans as a crime zone.B.He had high expectations of the future of New Orleans.C.He couldn’t put up with the suffering the hurricane caused.D.He was traveling the Midwest and the South with Walker Evans.CA little social support from your best buds goes a long way,whether you’re a human or a chimpanzee(黑猩猩).A new study that followed a chimpanzee community in the forests of Uganda has found that quality time with close companionssignificantly decreased stress hormone levels in the primates—whether they were resting,grooming or facing off against rival groups.The findings,described this week in the journal Nature Communications,shed light on the physiological effects of close companionship in chimpanzees—and could have implications for human health too.Researchers have long known that stress can worsen health and raise the risk of early death in humans as well as other social mammals.“It can have effects on immune function,cardio function,fertility,cognition,and even your mood,”said study coauthor Kevin Langergraber,a primatologist at Arizona State University.Maintaining close social bonds can help these animals(humans included)reduce some of that stress,potentially minimizing some health risks.But scientists have yet to pin down the exact physiological mechanisms at work.“Social bonds make you survive and produce better—but how do they do that?”Langergraber said.To find out,the international team of researchers studied members of the Sonso chimpanzee community in Uganda’s Budongo Forest,a group consisting of15males,35females and28juveniles and infants during the study period from February2008to July2010.Like humans,chimpanzees tend to have besties—bond partners with whom they appear to feel close.The researchers wanted to see whether interactions with these bond partners led to lower stress levels during particularly stressful situations, such as when fighting rival groups,or whether time spent with friends helped lower stress levels more generally,throughout the day.The scientists observed the chimps perform three types of activities:resting,grooming or quarrelling with other groups of chimps.The researchers kept track of whether the chimps were doing any of these three things with their bond partners or with other chimps in their group.A team of up to six observers watched the chimps and followed them around to collect urine(尿液)samples.The samples,collected from nine adult male and eight adult female chimps,were tested to see how much of the stress hormone cortisol they contained.The scientists found that chimpanzees’levels of urinary cortisol were23%lower,on average,during the activities when they were with their bond partner.This was especially true for stressful activities,such as the intergroup rivalries, where any chimp on the front line might face physical harm or even death.The findings in chimpanzees,some of our closest living relatives,could shed light on the role such close social relationships play in human health too,he said.Such friendships may be just as important during good times as bad—though more research needs to be done before any conclusions can be drawn.“This has interest for a lot of people in a medical context as well,”Langergraber said.61.The scientists carried out a research into chimpanzee community in Uganda______.A.to seek evidence of benefits of social bonds from physiological angleB.to uncover whether social bonds make humans surviveC.to study how chimps perform three types of activitiesD.to train chimps to maintain close social bonds with each other62.What does the underlined word“they”in Paragraph10refer to?A.Observers.B.Chimpanzees.C.Urine samples.D.Bond partners.63.The chimps’levels of urinary cortisol decrease most when______.A.they are with other chimps in their groupB.they face the intergroup rivalries with friendsC.they perform three different types of activitiesD.they spend time with friends throughout the day。

2024届江苏省南京市、盐城市高三上学期第一次模拟考试英语试题含解析
2024届江苏省南京市、盐城市高三上学期第一次模拟考试英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解Strawberry picking is a popular and enjoyable activity in Pennsylvania.The state’s favorable weather and long growing season make it a favorite pastime for both locals and tourists.Bricker’s StrawberriesIt is a family-owned farm in Carlisle,PA,offering pre-picked and pick-your-own berries throughout the year.Prices range from$2/pound for pick-your-own berries to$4.25/quart for pre-picked berries.Opening hours may vary depending on the weather,so it’s best to check their website before heading out to the farm.Oak Grove FarmsOak Grove Farms in Mechanicsburg,PA,has been a family-owned farm since the1960s.

But Shanya Gill,a middle schooler from San Jose,California,won the top award in the Thermo Fisher Scientific Junior Innovators Challenge for designing a fire detection system that is superior to existing ones,as stated in the press release.“The top winners have exhibited boundless curiosity,”Maya Ajmera president and CEO of Society for Science,said in the press release.“Their remarkable research not only reflects their talent but also paves the way for an exciting new future.”Shanya’s inspiration came after a fire destroyed a restaurant in her neighborhood during the summer of2022,reported The Washington Post.“I had never really experienced something like that before,”she told The Washington Post about the early morning fire at Holder’s Country Inn, which started in the kitchen.“They had smoke detectors.and yet it still burned down,”she added.After she studied fire statistics,Shaya spent over a year developing a fire detection system that she believes could have prevented the fire.Unlike traditional smoke detectors that sense active fires from the smoke in the air,Shanya’s thermal(热的)imaging device is designed to stop fires from occurring.With a thermal camera and a Raspberry Pi,a tiny computer the device detects when a heat source has been left unattended for ten minutes and sends a text message warning.Creating the prototype(原型)was difficult and the hardest part was the programming,“I had two designs,and my first design completely failed.It was a really big challenge I had to go through.”she said.The final device outperforms smoke detectors in speed and accuracy.Shanya wants to bring the costs down to make it even more common than hardwired smoke detectors.“Shanya saw a problem,went after it and tried to solve it,and that’s what we need toencourage with all young people,”said Ajmera.She also highlighted the significance of supporting individuals,especially girls and kids of color,in STEM fields,as research indicates that many young people drop out of these areas.4．What can we learn about Shanya from the first two paragraphs?A．She gained a lot of money in the award.B．She showed a curious nature as a schooler.C．She set a big stage for young people her age.D．She was junior to other winners in performance.5．What motivated Shanya to develop her fire detection system?A．Her desire to win the science award.B．Her experience of a destructive fire.C．Her interest in computer programming.D．Her goal to improve STEM education for girls.6．What is an advantage of Shanya’s invention?A．It consists of two parts that are easier to conduct.B．It can send out a warning against a potential fire.C．It can detect active fires from the smoke in the air.D．It functions when a fire breaks out within10minutes.7．Which of the following can best describe Shanya?A．Reliable.B．Cooperative.C．Innovative.D．Generous.Scientists have shown how plants can protect themselves against genetic(基因的)damage caused by environmental stresses.The growing tips of plant roots and shoots have an in-built mechanism(机制)that spells cell death if DNA damage is detected,avoiding passing on faulty DNA．Plants have small populations of stem cells(干细胞)at the tips of their roots and shoots, which enable them to continuously grow and produce new tissues throughout their lifetime.These stem cells serve as ancestors for plant tissues and organs.However,any genetic faults present in the stem cells will continue to exist and be passed on permanently throughout the plant’s life, which could last thousands of years.Given the critical role of stem cells and their exposure to potentially dangerous environments at the growing tips of roots and shoots,safeguards are necessary to prevent stem cell faults frombecoming fixed.Researchers Nick Fulcher and Robert Sablowski,funded by the Biotechnology and Biological Sciences Research Council,aimed to uncover these protective mechanisms. Through experiments involving X-rays and chemicals,they discovered that stem cells were more sensitive to DNA damage compared to other cells.When DNA damage occurs,the cells have the capacity to detect it and cause programmed cells to die,preventing the propagation of the damaged genetic code to the rest of the plant tissues. This process has similarities to the safeguard mechanism found in animal cells,which has been broadly studied due to its relevance in preventing cancer.The identification of a similar protective system in plants is of great interest in the field of plant development.It also helps scientists develop plants that can better handle environmental stress.So knowledge of how plants deal with these stresses is of fundamental significance to agricultural science’s response to climate change.8．What is the function of the in-built mechanism in plants?A．To produce more roots and shoots.B．To increase the overall lifetime of the plant.C．To enhance plant growth and nutrient intake.D．To stop genetic faults in stem cells passing on.9．What can we know about stem cells in plants according to the text?A．They are relatively abundant in quantity.B．They are resistant to environmental stresses.C．They make quick response to DNA damage.D．They have the ability to repair damaged DNA．10．What does the underlined word“propagation”in paragraph4mean?A．Spread.B．Change.C．Existence.D．Self-repair. 11．What does the last paragraph focus on?A．The way of dealing with climate change on the earth.B．The significance of identifying the protective system in plants.C．The method of ensuring plant survival under environmental stress.D．The urgency of developing plants that can handle environmental stress.Recently,I accidentally found a set of Hanfu l only wore once from the bottom of the cupboard.I remember buying them simply to match the ancient-style hair accessories(配饰)afriend gave me.It occurred to me that1had been trapped in the“birdcage effect”.“Birdcage effect”means that when you get an item one day,you will prepare more things to match it.Weeks ago,I was in the company of friends engaged in shopping.One said that she wanted to buy a good writing pen to match the delicate notebook that her sister gave her,so that she would fall in love with taking notes on reading,and thus love reading,not just reading.I joked that she must have fallen for the“birdcage effect”.But the friend said with a smile:“Why not use the‘birdcage effect’instead?”For the first time,I heard that the“birdcage effect”can be used in reverse(逆向).However, this can’t help but remind me of middle school,and I seem to have used the“birdcage effect”. Passing by a bookstore one day,I purchased a magazine and saw the call for contributions published in the magazine,so I started writing with eager hands,and then I fell in love with writing.After shopping with my friends that time,I began to proceed to use the“birdcage effect”.I bought a small fresh tablecloth to decorate my desk,and a beautiful notebook to record my inspiration.When everything was ready,I started writing again.But how can we get rid of the“birdcage effect”in many things,and even use the“birdcage effect”in the opposite way?Various“birdcages”unavoidably appear in life,but we can distinguish them.If it is not in line with the actual situation,it is a“negative birdcage”,then we must learn to stop losses in time and maintain a heart of abandonment and separation.If it is a “positive birdcage”that motivates us to develop upward,we can clarify our goals,shop or decorate appropriately,and motivate ourselves to move towards our goals.At this time,you will find that the“birdcage effect”is actually not so terrible!12．What is paragraph2mainly about?A．The application of the“birdcage effect”in life.B．The necessity of using the“birdcage effect”in life.C．The turning point of the author’s idea on the“birdcage effect”.D．The author’s conflict with her friend over the“birdcage effect”.13．What is the author’s purpose in mentioning her middle school experience?A．To recall her delightful days at school.B．To explain the reason for her love with writing.C．To confirm the positive of the“birdcage effect”.D．To prove her knowledge of the“birdcage effect”.14．How can we make use of the“birdcage effect”positively?A．By realizing this effect has two sides.B．By promoting our personal consumption.C．By recognizing this effect is not so terrible.D．By guiding our acts to go with reasonable goals.15．What can be a suitable title for the text?A．Getting Rid of the Birdcage Effect ConfidentlyB．Motivating Ourselves to Move Towards Our GoalsC．The Birdcage Effect:Influence on Consumer BehaviorD．The Birdcage Effect:How to Use It to Your AdvantagePursue Your Dreams Today,Not TomorrowHave you caught yourself daydreaming about your dreams?We often postpone our dreams, trapped in a cycle of delay.But why wait?16You don’t have to take a huge, life-changing step.You can take minute steps toward a brighter future.And start right now.17If you never try,you’re going to be weighed down by your regrets.You’re always going to wonder how your life would’ve turned out if you actually took a chance on yourself.Don’t let your future self be disappointed by your present self.It doesn’t matter how old you are or how many people have warned you that you’re never going to succeed.Even the most successful people have had their hesitations about whether they had what it took to make it in their field.18Embrace a mindset of determination, knowing that success is within your reach.At the end of the day,you need to carve out a path for yourself that will lead to the most satisfaction.If you allow your fear to get the best of you,you’re never going to forgive yourself.19.It’s what you would encourage your friends to do,so why aren’t you giving yourself that same push?Sometimes,following your passion means spending a lot of your time each day.It may require making slight adjustments to your schedule,but you don’t have to sacrifice everything tofollow your hearts.Try to strike a balance between your current life and your dreams.20 Pursue your dreams now,even though that means you might need to break out of your comfort zone,and even though it means entering the unknown.A．Ask yourself what would be worse.B．Starting small is completely acceptable.C．You owe it to yourself to go after your dreams.D．New opportunities may lead to personal growth.E．If things go well,you can gradually make further shifts.F．You need to move past your insecurities and explore your full potential.G．Hard as it is,it’s crucial to wave off the doubts in the back of your mind.二、完形填空In2008,Calvin Lowe's four-year-old son Tyler needed to have a serious surgery.On the appointed day of the21,he and his wife brought Tyler to Children’s Hospital Colorado in
