C’monJohnny is a lonely videographer immersed in a project interviewing kids about their thoughts about the future. His work is interrupted, though, when his sister Viv asks him to watch her son, Jesse. Johnny agrees and becomes a caregiver to his nephew. From caring for Jesse, he learns to understand better his own pain and what brings meaning to one’s life.EncantoThis film is about the Madrigal family — three generations living together.

So when he lost his dad to pancreatic cancer, he turned to the healing power of the ocean.At the start of this year, Fischer wrote his father’s name on his surfboard and took it out to sea in Newport, Rhode Island. His father’s name shone in the sun on what felt like a shared adventure. Inspired, Fischer made a video and posted it on social media the same day. “If you love the ocean, or you know someone who loves the ocean, or maybe you lost someone who just loved being outdoors..., you can comment on this video with their name and a bit of their story, and I’ll put their name on my board here, just like I’ve done with my father’s name,” he said in the video. “And I’ll take them out in the ocean for you.”Names poured in from thousands of strangers grieving (悲伤) the loss of loved ones. And with that, the One Last Wave Project was born, the aim of which was to exchange stories with a community of people going through the same pain. They were essentially healing together. About two months later, Fischer had received over 5,000 names and written most of them on two surfboards. The first two surfboards ran out of space — he’s working on getting more. He wrote the names in neat letters on the surfboard and put a clear acrylic (丙烯酸) coat over them so they didn’t wash off.Though a lot of people have been struggling with grief in the pandemic, Fischer was amazed by the responses that have poured in. “If I am able to help one person or one person shares their name, that is enough for me,” he said. “But I am blown away — by not just the number of people sharing, but the depth of stories and love that they are sharing.” And he plans to take his project around the world and connect with even more people — through shared grief and the power of the ocean.4.How did Fischer share his idea with others?A.By giving a live broadcast online.B.By posting a video on the Internet.C.By going to the beach with his father.D.By writing his father’s name on the surfboard.5.Why did Fischer start the One Last Wave Project?A.To memorize his father.B.To attract public attention.C.To face the pandemic bravely.D.To help people out of sadness. 6.What does Fischer intend to do next?A.Share his experience at sea.B.Extend the project worldwide.C.Connect to more social media.D.Sail around the world with strangers. 7.What can we learn from the story?A.Actions speak louder than words.B.He who laughs last laughs best.C.A good beginning makes a good ending.D.Sharing can help heal the pain.Every year thousands of people come to the city of Pamplona, in north-eastern Spain, for the opportunity to run for their lives as six fighting bulls are released to charge through the town. There are injuries and deaths every year, but the event is of interest to many people. A paper just published in Science describes the insight the event offers into the psychology of panicked crowds.That is a useful topic to explore. Arehitects, civil engineers and urban planners must try to work out how people will behave in the event of a disaster like a fire, a flood or a terrorist attack so they can design their creations to avoid potentially deadly collisions (碰撞). Unfortunately, solid information is hard to come by. Daniel Parisi, the paper’s lead author, realised that the Pamplona bull-runs offered the perfect natural experiment.Dr Parisi and his team went to two different rooftop locations in Pamplona in July 2019, and filmed the runners as the animals were released, Later in the lab, they calculated the speed of the runners, the density (密度) of the crowd, the probability of a runner tripping and falling and the relationship between runner-group density and speed.Perhaps unsurprisingly, the researchers found that runners picked up speed when the bulls drew near. Less expected was the finding that the speed of individual runners increased with the density of the crowd, which was contrary to a long-held assumption in architectural and urban-design circles that people will slow their pace as group density goes up, in order to lower the risk of a collision, which could lead to a fall and, perhaps, injury or death.Yet it seems that, in the heat of the moment, people pay little attention to the danger of colliding with each other, and do not slow down. The responsibility therefore falls upon urban designers to work out how best to plan the construction of future tunnels, bridges and otherpassages that restrict flow. The only option may well be to make them wider.8.What did Dr Parisi and his team do in Pamplona?A.They proved his theory.B.They recorded a bull-run.C.They watched a thrilling bull-fight.D.They designed a psychological experiment.9.What was the unexpected finding in the study?A.People slowed down in crowded areas.B.Tripping posed a danger to bull-runners.C.Bulls coming near made people running faster.D.People tended to speed up in high-density crowds.10.What is implied in the last paragraph?A.People lose their mind in disasters.B.Future tunnels and bridges may be wider.C.Panicked crowds are aware of the danger of collision.D.Restricting flow helps to prevent people colliding each other.11.Which is the best title for the text?A.How crowds react to panicB.Bull-runs caught on in SpainC.Dr Parisi’s finding shocks the worldD.What architects can learn from bull-runningAn individual from an unknown hominid (原始人类) species walked across a field of wet, volcanic ash in what is now East Africa around 3.66 million years ago, leaving behind a handful of footprints.Those five ancient footprints, largely ignored since they were partly unearthed at Tanzania’s Laetoli site in 1976, show features of upright walking by a hominid, a new study finds. Researchers had previously considered them hard to classify, possibly produced by a young bear that took a few steps while standing. But the latest analysis refutes that suggestion.McNutt, DeSilva, who started the new investigation as a Dartmouth College graduate student, and their colleagues fully dug out and cleaned the five Laetoli footprints in June 2019.Then they measured, photographed and 3-D scanned the ancient tracks. McNutt’s group focused on two footprints that were particularly well-preserved. Foot shapes, sizes, and walking characteristics of the Laetoli individual differed in various ways from those of other hominid individuals at the same site. The prints also didn’t match those from modern black bears and modern chimps (黑猩猩) walking upright.The Laetoli individual possessed a wider, more chimplike foot than humans, the researchers say. Its big toe stuck out slightly from the second toe (脚趾), but not to the degree observed in chimps. On one step, the Laetoli individual’s left leg crossed in front of the right leg, leaving a left footprint directly in front of the previous track. People may cross-step in this way when trying to regain balance. And bears and chimps assume a relatively wide standing due to knee and other bone arrangements that prevent them from walking like the Laetoli individual and probably from cross-stepping, the scientists say.Given that only two of the ancient footprints are complete enough to analyze thoroughly, the possibility that a chimp other than a hominid made the Laetoli footprints can’t be ruled out, says William Harcourt-Smith, a scientist at Lehman College. But evidence of cross-stepping is enough to prove that it was a hominid track maker, he says.12.What does the underlined word “refutes” in Paragraph 2 mean?A.Objects to.B.Supports.C.Puts forward.D.Criticizes. 13.Why do researchers think the footprints were unlike those of bears or chimps?A.They are less chimplike.B.They have toes sticking out.C.They show a wider standing.D.They get features of cross-stepping. 14.What does William think of the new research finding?A.Challenging.B.Convincing.C.Confusing.D.Conflicting.15.What is the purpose of the text?A.To share a new discovery.B.To describe a major event.C.To settle a huge disagreement.D.To introduce an unknown species.二、七选五Do you suffer from low energy? Is it difficult to get out of bed in the morning? Do yourworkers surveyed by Deloitte said they had experienced burnout. And 90% of those said that stress had negatively impacted their work.Burnout is dangerous. It can lead to mental and physical exhaustion, a loss of identity, and feeling a lack of accomplishment, they harm the body over time. Do you want to get out of this state? 17One way you can help relieve burnout is by practicing communication. Be clear about what you’re feeling, and if you are being overworked, discuss it with your supervisor or coworkers. 18 Taking time off is also a good idea.While self-care is trending these days, it will not cure burnout. 19 Their support and cooperation can make you feel better. Another option is taking part in regular physical activities to get your mind off work.20 A study cited by The New York Times found that surgeons who made time for recreational activities were less likely to experience burnout than those who didn’t. A few ideas for relaxing activities can be yoga, meditation, or mindfulness.A.As a matter of fact, you aren’t alone.B.Finally, make time to do things you love.C.Burnout can also develop along with anxiety.D.Read on to discover how to deal with it effectively.E.Provide them with ideas that would help lighten burnout in the office.F.What can help address the problem is to see a doctor or meet with friends.G.If you are eating more or less than usual, stress hormones can be affecting your appetite.三、完形填空Today’s birthday gift was to my friend Oscar in Portland who is unhoused.

2023届辽宁省大连市第八中学高考适应性测试英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读理解From a multi-day trek to a classic clamber,there are thousands of incredible trails that allow us to get close to nature.Appalachian Trail,United StatesExtending for2,200miles,the Appalachian Trail is listed as the longest hiking—only footpath in the world.It runs from Springer Mountain to Mount Katahdin,passing through some of the most remote country in the US.That means it’s a task,either for those with endless vacation allowance,or walkers looking to do a small piece of a classic route. Well-marked paths and campsites mean it can be tackled alone.Mount Toubkal,MoroccoNorth Africa’s highest peak at4,167meters,a hike to the top isn’t for the faint-hearted. The path rises from a village and on towards a large mountain hut.After overnighting here, hikers set off up the snowfield to the summit,where the Atlas Mountains open out and the views are relentless.The Basho Wayfarer,JapanThe six-day trek starts in Sendai and works its way through the northern region,passing through the UNESCO World Heritage Site and along the ancient Dewa Kaido path,heading into the mountains and finishing at the temple of Yamadera.The Dingle Way,IrelandStretching111miles,The Dingle Way is a circular path that offers the best way to get under the skin of wild County Kerry in Ireland’s south west.Starting in the town of Tralee, the clockwise path follows narrow roads,taking in the wide sweep of sand at Inch Strand, passing along the cliff tops and heading around the edge of Mount Brandon. 1.Appalachian Trail in the US is suitable for the hikers__________.A.who challenge it as a task.B.who needn’t go to work at all.C.who have a big traveling budget.D.who want to explore lonely places. 2.Where can hikers enjoy a good view of snow scenery?A.The Dingle Way,Ireland.B.Mount Toubkal,Morocco.C.The Basho Wayfarer,Japan.D.Appalachian Trail,United States.6.What made Warren feel happy?A.The good sales of the benches.B.The assistance from other people.C.The comments on Twitter.D.The awards from the local government. 7.What is Warren’s true purpose of organizing the workshop?A.To earn more money to live a better life.B.To set up his own bench-building workshop.C.To encourage people to use more public transit.D.To make people live a little bit better.You might have heard someone say that a song changed their life.And maybe you used to hate tomatoes,but now you like it.No one doubts that we change as we grow older.But do we change in major ways?Can we really change who we are?People used to believe we stay pretty much the same throughout our lives,but researchers are increasingly finding that we can and do change in big ways.Psychologists have identified five dimensions that help us understand someone’s personality,which are called the“Big Five.”They are:1.Openness:How open are you to trying new things?2.Conscientiousness(尽责性):How responsible are you?3.Extroversion (外向):How friendly,outgoing,and enthusiastic are you?4.Agreeableness:How caring, trusting,and generous are you?5.Emotional stability:How calm are you,especially when problems arise?Everyone has different levels of the big five dimensions.For example,Harry Potter has high levels of openness to experience,while Hermione Granger would score high in conscientiousness.Scientists used to think that each person’s“Big Five”stayed the same their whole life, but newer research suggests that the dimensions do change.People who took a personality test as teen-agers scored very differently when they took the same test50years later.Three dimensions usually changed more than the others,which are emotional stability, conscientiousness,and agreeableness.In fact,most adults were more emotionally stable, more conscientious,and more agreeable than when they were younger.Researchers considered this a sign that we mature over time,perhaps learning to get along better with others.Even though people change over time,the relationship between dimensions often remains similar.For example,someone who was very open to new experiences but who wasnot agreeable as a teenager was likely still more open to new things than agreeable as an adult. Scores changed,and sometimes changed a lot,but they didn’t change randomly.8.Why does the author mention Harry Potter and Hermione Granger in Paragraph2?A.To identify the impact of the big five dimensions.B.To stress the value of openness and responsibility.C.To analyze some main characters in popular fiction.D.To illustrate various degrees of personality dimensions.9.Which of the following is the most likely result of people’s aging?A.Becoming more hot-tempered.B.Becoming more considerate.C.Becoming less responsible.D.Becoming less generous. 10.What does the last paragraph suggest about one’s personality dimensions?A.Personality dimensions change accidentally.B.One is likely to be more open than agreeable.C.Relationship between dimensions stays unchanged.D.Changes in personality dimensions follow some pattern.11.Which of the following is a suitable title for the text?A.The Effects of Changing.B.What Are the“Big Five”?C.Do People Really Change?D.Personality Dimensions Matter.As people travelling by air become increasingly aware of their carbon footprint,flying has become not only one of the most polluting industries,but also one with the most potential to turn things around.After Solar Impulse2completed the world’s first flight by a solar-powered aircraft in 2016,airlines and aircraft producers looked to become the first to provide a commercial plane. Bertrand Piccard,one of the pilots responsible for Solar Impulse2’s journey said,“All the clean technologies we’ve already had can be used everywhere.We have to use them,not only for the environment,but also because they are profitable and able to create jobs.”The following year saw many projects in the aviation(航空)field as the airline industry acknowledged the future of low-carbon transportation methods.In2017,Zunum Aero,a small aviation company which focused on delivering a range of hybrid-electric(混合电动的) planes received financial aid from JetBlue and Boeing,whilst EasyJet teamed up with Wright Electric to develop battery-powered aircraft and NASA also announced its plans to developits own electric aircraft.Orkney Islands,lying about20miles north of the Scottish mainland,are rich in renewable resources,especially the wind energy.Loganair,a Scottish airline,is cooperating with aviation companies to make Orkney the world’s first fully electric airline routes. However,this is never easy.Due to the limited size and weight of a battery that an airplane can carry,airplane producers are faced with a bottleneck—the continued power supply for electric airplanes.They believe the abundant wind energy in Orkney could be the key to solving it.The benefits of electric air travel transcend its low-carbon emissions.Aviation experts believe these aircraft’s power source will also mean they will be less noisy,smaller,require less maintenance costs,and need a shorter runway to take off and land—this could lead to more airports in small cities and more rural areas being connected to the world at large. 12.What did Bertrand want to convey in his words?A.The future of aircraft pilots.B.The success of Solar Impulse2.C.The convenience of commercial planes.D.The significance of using renewable energy.13.How did EasyJet carry out the low-carbon transportation methods?A.By asking for financial support from banks.B.By cooperating with another company.C.By purchasing patents from other countries.D.By improving the technology on its own.14.What will airplane producers probably do to make Orkney’s electric airline routes a reality?A.Use natural resources to charge airplanes.B.Build more coal-fired power stations.C.Develop shorter airline routes.D.Increase the size of battery.15.What’s the benefit of electric planes besides its green footprint?A.Making plane tickets cheaper.B.Making the flying time shorter.C.Making the world more connected.D.Making the plane maintenance easier.二、七选五三、完形填空四、用单词的适当形式完成短文五、图表作文六、读后续写47.阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。

所以{an} 是首项为 1,公比为 2 的等比数列,
an = 1× 2n-1 = 2n-1
Qa1 = 1 ,符合上式
所以{an} 是通项为 an = 2n-1 的等比数列,A 选项正确;
对于 B,已知 Sn = 2n +1 ,所以 Sn+1 = 2n+1 +1 , a1 = S1 = 21 +1 = 3
Sn+1 - Sn = 2n+1 - 2n = 2n an+1 = 2n an = 2n-1
Q a1 = 3 ,不符合上式 所以,B 选项错误;
对于 C,已知 an+1 = 2an ,当首项为零时,不符合题意,C 选项错误;

He had just parked around the comer from his own house when he got a call from his daughter: "The house next door is on fire!" He went to look. That's when he saw an old woman crying outside."The baby's in there!" she cried. Though the fire department had been called, Surrell, then 64, ran inside without hesitation. Entering the burning house was like "running into a bucket of black paint," Surrell says. The thick smoke burned his eyes and made it impossible to breathe. The conditions would have been dangerous for anyone, but for Surrell, who had lung disease, they were life-threatening.After a few minutes in the smoke - filled house, he retreated outside to catch his breath. "Where is Tiara?" he asked desperately.“The second floor," the old woman shouted back.Taking a deep breath, Surrell went in a second time. Because the house had a similar layout to his, he found the stairs and made it to the second floor.“Baby girl, where are you?”His throat and lungs burned as if he'd breathed fire instead of the smoke in the air. He couldn't open his eyes. All he could hear was the crackling (破裂声)of burning wood. Then a soft sound came out. Still unable to see, Surrell fell to his knees on the hot wood floor and climbed toward the sound, feeling around for any sign of the girl.Finally, he touched something. A shoe, then an ankle. He pulled the baby toward him. Her body was weak and she wasn't breathing. He carried her into his arms and ran blindly into the blackness. The next thing he knew, he was at the front door, then outside.4.Why was the old woman crying outside?A.She lost the baby in the fire.B.The baby was hurt in the fire.C.The baby was in the burning house.D.She couldn't call the fire department.5.What can be learned from the first two paragraphs?A.Surrell's daughter worked in a fire department.B.Surrell would probably have been killed by the fire.C.The smoke blanketed Surrell' s house from next door.D.A bucket of black paint blocked Surrell's way to the house.6.How did Surrell find the baby on the second floor?A.By searching on his knees.B.By opening the back door.C.By shouting repeatedly'D.By turning on the light.7.Which of the following best describes Surrell?A.Determined and patient.B.Independent and devoted.C.Generous and reliable.D.Courageous and caring.Scientists say a huge percentage of bird species are in danger because their habitats are disappearing.The scientists studied the migration, or flight, paths, of almost 1,500 species and decided that 91 percent of them passed through dangerous areas. The major danger for migratory birds is development. Building and paving have covered over nature where birds stop and feed as they move from one part of the world to another.For example, a bird called the bar-tailed godwit migrates from its breeding grounds in the Arctic. It flies all the way to Australia and New Zealand. The problem, according to investigators, is that many of these small birds die along their migration because they don't have a safe place to eat and rest. There is no place to restore their energy for the next part of their journey. "They simply perish along the way," says one of the scientists.Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time conserving land. The scientists say these countries do not have enough areas that are safe for birds."Our world gets poorer every time we lose a species,’’ one of the scientists says.The researchers say countries need to work together and come up with safe stopover areas for birds that pass through their boundaries.For example, one country might have preserved safe zones for migrating birds. But aneighbor country might not. A bird might die.One scientist who is not involved in the report tells the Los Angeles Times that while some habitats are changing, more work can be done to make urban areas safe for birds. He says small changes—like planting more native plants or keeping cats out of areas birds would be likely to use—could make a big difference.8.What’s the major danger for migratory birds according to the passage?A.They can’t find enough food along the way.B.They have lost their way because of human development.C.Human development has occupied their natural habitats.D.They are sometimes struck by human diseases.9.What do we know about bar-tailed godwits?A.They fly from the Arctic south to Australia every year.B.They can pick out good resting place along the way.C.They have died out because of human hunting.D.They have their conserved land in Australia.10.Which of the following is closest in meaning to the underlined word "perish" in Paragraph 3?A.Continue.B.Die.C.Settle.D.Migrate.11.What suggestion does the scientist say to the Los Angeles Times?A.Countries working together to protect the sea.B.Protecting the original habitats for the migrating birds.C.Reserving some land for the birds to rest along the way.D.Planting some native plants for the migrating birds to use.Do you still remember the scene in the famous movie Titanic, directed by Cameron, where Jack was frozen to death in the icy cold water so that Rose could survive on the floating door alone? It broke many people’s heart.Two decades later, people are still asking the question, “wasn’t there enough room on the door for both of them?”Cameron once responded by saying it wasn’t a question of room, but buoyancy (浮力) — if both of them had tried to stay on the door, he argued, the whole thing would sink.But several guys from “Mythbusters”, an Australian-American science entertainment television program, decided to test the theory themselves. They discovered that if Rose had took off her life jacket to the bottom of the door, there would have been enough buoyancy to keep both of them afloat.“It was an artistic choice, the thing was just big enough to hold her, and not big enough to hold him,” Cameron said. “I think it’s all kind of silly, really, that we’re having this discussion 20 years later. But it does show that the film was effective in making Jack so attractive to the audience that it hurts them to see him die. The film is about death and separation; he had to die.”Since Jack was doomed to die, Cameron said, it could have happened in a variety of different ways. It’s not about the door not being big enough: that’s just a practical method for his death. “Whether it was that, or whether a chimney (烟囱) fell on him, he was going down,” Cameron said. “It’s called art: things happen for artistic reasons, not for physics reasons.”12.What do we know about the character Jack according to the text?A.He intended to kill himself.B.He sacrificed himself to save Rose.C.He didn’t have money to buy ticket.D.He lacked basic knowledge of physics. 13.According to Cameron, why can’t audience accept Jack’s death?A.They are artistic people.B.They like the movie.C.They love the character Jack.D.They are eager for truth.14.The best title for this passage is________.A.Jack in Titanic Had to Die.B.Big Enough for Both.C.Cameron Is Wrong.D.Jack Could Survive.15.Where can you probably find this article?A.A movie poster.B.A notice board.C.A government report.D.A popular magazine.二、七选五Should You Drink Milk Before Bed?May help some people fall asleep fasterMay consuming dairy products like milk and cheese before bed help some people have a more restful night’s sleep? 16 But the reason why remains unclear.Most experts agree that milk’s sleep-promoting potential is likely related to specific chemical compounds (合成物) or the psychological effects of having a soothing (舒缓的) bedtime routine—or perhaps a combination of the two.May promote healthy sleep cyclesCertain compounds in milk—specifically tryptophan (色氨酸) and melatonin (褪黑素)— may help you fall asleep. 17 Studies have found that taking supplements of these compounds may improve sleep and reduce symptoms of anxiety and depression that can appear at bedtime.However, there’s currently no evidence to suggest that a single glass of milk contains enough tryptophan or melatonin to significantly influence your body’s natural production of melatonin or to independently treat a disordered sleeping pattern.18Some experts suspect that milk’s potential role as a sleep aid has little to do with its nutrition and that it’s instead more closely related to the psychological effect of having a calming bedtime habit.Another theory is that drinking warm milk could remind you of having milk at bedtime during your early childhood years. 19SUMMARYMilk contains several compounds known to support healthy sleep cycles. Plus, the psychological effects of a bedtime routine that includes milk may improve your ability to fall asleep. 20A.But more researches are needed.B.Psychological effects.C.Let’s explore the relationship between milk and sleep.D.These feelings may signal to your brain that it’s time to sleep.E.Many people have to drink warm milk before going to bed.F.The role of tryptophan and melatonin in sleep disorders is well established.G.A handful of small animal and human studies demonstrate (表明) that the answer is Yes.三、完形填空Half a year before graduation from college, my son began to look for a job.
