As the most intelligent creatures to ever walk the earth, we tend to assume that we are the only ones who can feel emotions. We forget that the speechless beings who live here with us—animals—also have the same capability.During a cold night in Ontario, Canada, a passer-by spotted something on the side of the road that made her stop-a shaking dog curled up in the snow.When she approached the pet, she discovered that she wasn't alone—she was cuddling five orphaned black kittens to keep them warm.The dog surely could have found a safer place to stay for the night, but she chose instead to help not just herself but other stray animals as well.The Good Samaritan called Pet and Wildlife Rescue and an animal control officer picked them up. When they got to the shelter, it was apparent that a close bond had already been formed between the dog and the orphaned kittens. The staff decided to name the kind dog Serenity in honor of her selfless act.“It's truly heartwarming!” a shelter spokesperson told The Dodo. "It had been a very cold night so these kittens would have had a very hard time surviving.”Aside from requiring treatment for worm and flea infections, the orphaned kittens are now safe. Just like a proud and doting mother, Serenity insisted on checking on her babies regularly to oversee their progress.The good news is that the kittens are now living with a foster family who will care for them until they are old enough to be adopted. Serenity, on the other hand, is still looking for a family.According to the shelter, she loves zooming around in the yard and is big on playing. She is also quite jumpy, so she would do best in a home without small children.4.What did the passer-by see on the road?A.A dog curled up in the snow.B.Five kittens were in the snow alone.C.A dog found a safe place to stay for theD.A dog was warming five kittens in the snow. night.5.What does the underlined word "she" in paragraph 3 refer to?A.The passer-by.B.The spokesperson.C.The kitten.D.The dog.6.Where is the dog Serenity now?A.Being adopted by a family.B.Living in the shelter.C.Staying with the kittens.D.Playing with some children.7.What can we draw from the story?A.Animals have the same capability with humans.B.A sad end can be turned into a positive one.C.Animals and humans should live in harmony.D.Animals can feel compassion and love like humans.health than eating first, according to a study of meal timing and physical activity.Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men’s fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.Then, on two separate morning visits to the scientists’ lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.Just before and an hour after each workout, the scientists took additional samples of the men’s blood and fat tissue.Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they hadskipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.8.The underlined expression “stomach it” in Paragraph 1 most probably means “______”.A.digest the meal easily B.manage without breakfastC.decide wisely what to eat D.eat whatever is offered9.Why were the 10 people chosen for the experiment?A.Their lifestyles were typical of ordinary people.B.Their lack of exercise led to overweight.C.They could walk at an average speed.D.They had slow metabolic rates.10.What happened to those who ate breakfast before exercise?A.They successfully lost weight.B.They consumed a bit more calories.C.They burned more fat on average.D.They displayed higher insulin levels. 11.What could be learned from the research?A.A workout after breakfast improves gene performances.B.Too much workout often slows metabolic rates.C.Lifestyle is not as important as morning exercise.D.Physical exercise before breakfast is better for health.Hollywood’s theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics(控制论),put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard.The possibility of entering into and losing such a match should concentrate the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.12.Paragraph 1 mainly tells us that artificial intelligence may .A.run out of human controlB.satisfy human’s real desiresC.command armies of killer robotsD.work faster than a mathematician13.Machines with specific purposes are associated with living things partly because theyA.prevent themselves from being destroyedB.achieve their original goals independentlyC.do anything successfully with given ordersD.beat humans in international chess matchesA.help super intelligent machines work betterB.be secure against evil human beingsC.keep machines from being harmedD.avoid robots’ affecting the world15.What does the author think of the safety problem of super intelligent machines?A.It will disappear with the development of AI.B.It will get worse with human interference.C.It will be solved but with difficulty.D.It will stay for a decade.二、七选五Babies’ Look ChangingResearchers show that the early social behavior called look changing is linked to babies’ ability to learn new language sounds. 16 . It is when a baby makes eye contact and then looks at the same object that the other person is looking at.Rechel Brooks, one of the researchers, made a report, showing that babies’ look changing serves as a building block(基础)for more complicated language and social skills.17 .In this experiment, nine 5-month-old babies from English-speaking families attended foreign language tutoring sessions. Over four weeks, the tutors talked and played with toys while speaking Spanish.At the beginning and end of the four-week period, researchers counted how often the babies changed their look. 18 . There they tested how much Spanish language sounds.19 . The more look changing the babies participate in during their tutoring sessions, the greater their brain response were to the Spanish language sounds.“Our findings show young babies’ social engagement contributes to their own language learning – they’re not just passive listeners of language,” Brooks said. “They’re paying attention and showing parents they’re ready to learn when they’re looking back and forth.”20 .The researchers hope their findings help people develop strategies for teaching young children.A.That’s when the most learning happensB.These skills are what preschool children can gainC.The results were really amazingD.We can’t imagine how look changing helps them learn so muchE.However, others may regard look changing as something uselessF.Look changing is one of the earliest social skills that babies showG.After the experiment ended, the researchers brought the babies back to the lab三、完形填空Christmas was near a season that we took seriously in our house.

2021届烟台市中英文学校高三英语上学期期末试卷及答案解析
2021届烟台市中英文学校高三英语上学期期末试卷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AI once taught in a small private school. Each morning at nine o’clock all the students, ranging in age from three to seven years old, gathered in the Great Room for a warm-up in preparation for the day.One morning the headmistress made an announcement to all the children gathered,“Today we begin a great experiment of the mind.” She held up two ivy(常春藤) plants, each potted in an identical container. She continued, “Do they look the same?”All the children nodded. So did I, for, in this way, I was alsoa child.“We will give the plants the same amount of light, the same amount of water, but not the same amount of attention,” She said. “Together we are going to see what will happen when we put one plant in the kitchen away from our attention and the other plant right here in this room. Each day for the next month, we shall sing to our plant in the Great Room and tell it how much we love it, and how beautiful it is. We will use our good minds to think good thoughts about it.”Four weeks later my eyes were as wide and disbelieving as the children’s. The kitchen plant was leggy and sick-looking, and it hadn’t grown at all. But the Great Room plant, which had been sung to and surrounded by positive thoughts and words, had increased threefold in size with dark leaves that were filled with energy.In order to prove the experiment, the kitchen ivy was brought to the Great Room to join the other ivy. Within three weeks, the second plant had caught up with the first ivy. Within four weeks, they could not be distinguished, one from the other.I took this lesson to heart and made it my own.1. Why did the headmistress do the experiment?A. She wanted to teach me a lesson.B. She expected the students to learn to grow plants.C. She meant to prove the impact of good minds on growth.D. She intended to show students how to save a sick-looking plant.2. What happened to the ivy in the kitchen at last?A. It stopped growing and died.B. It was leggy and sick with dark leaves.C. It looked almost the same as the other one.D. It grew better than the one in the Great Room.3. What can be a suitable title for the passage?A. Life Means GrowthB. Things Grow with LoveC. Equality Makes a DifferenceD. Positive Thoughts Really CountBMany of us were delighted to learn that a high school senior Kwasi Enin was accepted to all eight Ivy League universities. To our surprise, he wasn't excited as expected, but appeared extra calm. He announced that he would revisit the universities to find the best suitable in music or medicine. He also wanted to compare their financial aid packages.Kwasi's success story is rare, but his reaction is not. After the admission letters arrive at home, students have 30 days to really think about what kind of school would help them grow as a person, which school would best prepare them for the future, and at which school they would be happiest. And they also have to think about whether they can afford the school they choose.But how to answer the questions about which school is the best suitable university? Some young people are attracted to large universities with great school spirit and a list of offerings. But besides those advantages, many of these universities focus on graduate work and research, with undergraduates taught mostly by part-time instructors. Others are attracted to smaller boarding schools with discussion-based classes. But some of these schools will have much limitation for students who want a high-energy city life experience.Many students today seem to think they should pick the university where they will get the diploma that will help them get the most highly paid job. This is a sad misunderstanding of what a college education should provide.A good college education should prepare them to overcome any difficulty andthrivein society. It helps them to form the habit of creative mind and spirit that will continue to develop far beyond their university years. So when you choose college, you should consider if it is filled with useful learning to help create new spaces for different possibilities of growth.4. What can we know about Kwasi Enin from paragraph 1?A. He was from a very poor family.B. He would choose the top university.C. He was too excited to calm himself at the good news.D. He considered his interests when choosing his university.5. What can you infer from paragraph 2?A. Few students can be admitted to university.B. Many students face the choices like Kwasi.C. Top universities are the first choice for most students.D. American students can afford their university by themselves.6. Which of the following can best explain the underlined word “thrive” in paragraph 4?A. FailB. SucceedC. ResearchD. Work7. What should the best university be like according to the text?A. Very large and have good instructors.B. Small boarding schools with discussion-based classes.C. It will offerthe diploma to get the most highly paid job.D. It will help continue to develop far beyond university years.CHi, Momis a hit inChina. Since its release in early February the movie has earned more than 5 billion yuan at the box office.

Some of her fifth-grade classmates at Hopewell Memorial Junior High School sit on high-top chairs at counters. Others choose to sit in club chairs or soft bean bags in comfortable. "I like it because it gives us an environment we like or need to settle down and read a book that we would like to concentrate on instead of having desks and being all quiet," said Vivian Garcia, 10. “You can just space out and have your own little area. I find it very amazing that you can pick your own books instead of being told what to read.”That’s the end goal, said teacher Heather Shadish. Reading has always been a passion for this English language arts and science teacher, a passion she instills(灌输)in her pupils. Back then, in her literature class in graduate school at Chatham University, a professor read aloud the first chapter ofBecause of Winn-Dixieby Kate DiCamillo, a Newbery Medalist. "That was the moment I knew I wanted to some day teach reading. There was a spark there. I just felt these are the kind of books I need to share with kids ---the books that are going to make them feel something and make them fall in love with reading instead of reading being achore.”But information in children's workbooks is limited, so they open tablets and connect to Epic - a digital library that's free to educators and librarians, but $7.99 a month for parents — giving kids unlimited access to approximately 35,000 books(both print and audio), quizzes and videos to enhance learning.“Epic gives students access to information not found in a textbook and presents it in a more interesting way," she said.12. What does Vivian think of the reading experience?A. She favors club chairs and free discussion.B. She feels comfortable to be told what to read.C. She enjoys the environment and reading choice.D. She finds it easy to pick a book in a crowded area.13. What does the underlined word “chore" in paragraph 2 mean?A. Task.B. Process.C. Habit.D. Skill.14. What can children get from Epic?A. Free audio books.B. Tasks on reading levels.C. Advice from educators.D. Useful learning resources.15. Which of the following is the best title of the passage?A. A Teacher's New Reading MethodB.

After all, she’s already got her master’s degree.The North Chicago-area teen started homeschooling at the age of 4. She began having an influence on others soon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, which is for people who were forced to leave their homes because of earthquake, flood and other natural disasters.At the age of 11, she graduated from high school and then earned her bachelor’s degree in psychology in 2013. She completed those classes online as she was traveling for church events and leadership meetings.She doesn’t stop there, though. The teen plans to focus on aviation psychology (航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took fights all the time. Her goal is to use it to help pilots deal with problems that could have deadly results once the plane takes off — a topic that has been in the news lately. For her, it’s a mix of two of her interests.In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group at church.

Scott Kelly said he tried to express that view everywhere he went. And he spoke from experience, having spent a career that included the time as a NASA astronaut, US Navy captain, fighter pilot, and engineer.Scott spoke at the University of North Alabama, sharing stories about his experience of spending a year on the International Space Station (ISS). He said the physical pressure of living in weightlessness for a year was hard to describe and that the fluids(积水) in his head sometimes made him feel like he was standing on his head. It also needed some time to recover when he returned home. “My legs were weak and it would be uncomfortable to sit for a while because my body hadn’t had that pressure so long,” Scott said.He discussed life aboard including spending time with Russian astronauts. They came from different cultures. He had managed to get along well with everyone aboard as they lived together, worked together, and had to rely on each other. He thought it was one of the most rewarding things in his life.Though life there was not easy, Scott never regretted being an astronaut and going to space. He also discussed experiences growing up, admitting that he wasn’t always the greatest student but was able to overcome that through hard work and determination.“Never give up or lower your dreams. If you work for it, all things are possible. There is a zero percent chance of succeeding if you don’t even try. And when you succeed after trying hard, you’ll find it really rewarding,” Scott said in the end.8. Scott mentioned his experience in the ISS mainly to show ________.A. he enjoyed making speechesB. he was a responsible astronautC. his life in space was challengingD. the daily life of an astronaut can be boring9. What may benefit Scott most when he lived with Russian astronauts?A. He won some awards through teamwork.B. He found the fun of living in the Space Station.C.

Easy things are also worth doingC. A suitable career leads one to success.D. Difficult things are demanding but rewardingDHappiness is not a warm phone, according to a new study exploring the link between young life satisfaction and screen time. The study was led by professor of psychology Jean M. Twenge at San Diego State University (SDSU).To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.On average found that teens who spent more time in front of screen devices — playing computer games,using social media, texting and video chatting — were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions."The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising — two activities reliably linked to greater happiness."Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of screen devices over time happened at the same time as a general drop-off in reported happiness inU. S.teens. Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep.12. Which method did Twenge's team use for the study?A. Calculating students' happiness.B. Asking students certain questions.C. Analyzing data from a survey.D. Doing experiments on screen time.13. How does the author develop the finding of the study in paragraph 3?A. By making a comparison.B. By giving an example.C. By making an argument.D. By introducing a concept.14. What is the purpose of the last paragraph?A To draw a conclusion from the study.B. To offer some advice to the readers.C. To prove social activities' importance.D. To support the researchers' finding.15. Which of the following can be the best title for the text?A. Quitting Phones Equals HappinessB. Screen Time Should Be BannedC. Teens' Lives Have Changed SharplyD. Screen-addicted Teens Are Unhappier第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

2021届烟台市双语实验学校高三英语上学期期末试卷及参考答案
2021届烟台市双语实验学校高三英语上学期期末试卷及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项APersonal Time Off(PTO)is something my wife and I created after having kids. We learned that,over time,a full life can leave little time for personal rest and for reflection,hanging out with friends,or just being“off. ”So,after a number of years,we make a change. If I can persuade you to take your own PTO,then these might help.■Schedule itFirst of all,one of our favorite family sayings is“schedule it. ”Sounds easy enough,but life gets complicated managing full-time work and full-time family. Put yourPTO time on the calendar and you make it a real thing.■Be flexible and strictIf you can schedule PTO at the same time each week,then all the better. Because our calendar can get rather full,flexibility in scheduling becomes a necessity. But being strict in actually taking the time each week is more important. Skipping it once makes it easier to skip again.■Take enough timeMy typical PTO lasts a couple of hours or longer. Sometimes it might be half the day depending on what I’m doing. The goal is to spend enough time away to1et your shoulders drop.■Do what you want to doRemember,PTO time is about personal time to do what you want to do,not what you have to do. PTO time is about relaxation. Grab a friend and get a beer. Work can wait until tomorrow.1.What can be the first step to take the PTO?A.Persuade the family.B.Have a personal rest.C.Ask friends for advice.D.Make a time plan.2.What does the underlined part“let your shoulders drop”probably mean?A.Get you more focused.B.Have you feel relaxed.C.Shake your shoulders often.D.Make you feel more stressed.3.What does the text mainly talk about?A.Tips on how to take your time offB.Skills to manage work and familyC.Advice on how to free yourselfD.Ways of scheduling your workBWhile space travel still gets lot of attention, not enough attention has been paid to the exploration of oceans, about which we know much less than the dark side of the moon.Ninety percent of the ocean floor has not even been recorded and while we have been to the moon, the technology to explore the ocean's floors is still being developed. For example, a permanent partially-underwater sea exploration station, called the Sea Orbiter, is currently in development.The oceans play a major role in controlling our climate. But we have not learned yet how to use them to cool us off rather than contribute to our overheating. Ocean organisms are said to hold the promise of cures for a wide of the unique eyes of skate (ray fish) led to advances in conquering blindness, the horseshoe crab was important in developing a test for bacterial pollution, and sea urchins helped in the development of test-tube fertilization(人工授精). The toadfish's' ability to regenerate its central nervous system is of much interest to neuroscientists. A recent Japanese study concluded that the drug Eribulin, which was taken from sea sponges, is effective in fighting with breast, colon, and Urinary cancer.Given the approaching crisis of water insufficiency, we badly need to improve current methods, of desalinating(淡化) ocean water and make them more efficient and less costly. By 2025, 1.8 billion people are expected to suffer from severe water shortage, with that number jumping to 3. 9 billion by 2050-well over a third of the entire global population.If the oceansdo not make your heart go beating faster, how about engineering a bacterium that eats carbon dioxide — and thus helps protect the world from overheating — and produces fuel which will allow us to drive our cars and machines, without oil? I cannot find any evidence that people young or old, Americans or citizens of other nations would be less impressed or less inspired with such a breakthrough than with one more set of photos of a faraway galaxy or a whole Milky Way full of stars.4. What does the author think about the ocean exploration?A. It is equal to the space exploration.B. It is well developed.C. It deserves more attention and devotion.D. It is beyond our knowledge.5. What technology has been developed to make use of the oceans?A. Curing human diseases with ocean organisms.B. Preventing the world getting warmer.C. Mapping the global ocean floor.D. Removing salt from sea water.6. What does the author imply in the last paragraph?A. The temperature rise will be overcome by a bacterium.B. Solving the existing problems is more significant.C. The space exploration is worth the efforts.D. The ocean exploration is not inspiring.7. What is the best title of the passage?A. Oceans, the Last Hope.B. Oceans, the Hidden Treasure.C. Space, the Final Frontier.D. Space, the Faraway Dream.CKids ages 6 to13 inCape Town,South Africa, really do dig learning at school! With the help of the Earthchild Project, which is offered in schools in two townships, students make worm(蠕虫) farms. The worms break down food waste and make the soil richer.

In some communities inCape Town, children live in poverty. They must walk long distances to get clean drinkingwater. Life is hard.

The differences between traditional lessons and Earthchild Project.DSusan Scott, 71, is glad that she didn't think about her age when she took up bodybuilding at the age of 59.“I reinvent myself every ten years. I started my 60s as a bodybuilderand now I'm beginning my 70s as a writer,” she said. “People usually limit themselves by age, and it's discouraging.

But she also develops her mind and spirit. On any given day, she gets up at 3 am to read books. At 4:30 am she's out to walk three miles and run another three. This is followed by yoga and a swim at the beach while the sun rises. After writing her journal and working on her book between 8 and 10 am, she hits the gym for at least two hours. “I don't lose track of time,” she said.Dr Susan's war on ageism has rubbed off on her two daughters, both in their early thirties. “They both take care of their bodies and minds. If you give them a good foundation as a parent, you know that they will always come back to their roots. I tried to remind myself of that during their difficult teen years.”12.

2021年烟台市中英文学校高三英语上学期期中考试试题及参考答案
2021年烟台市中英文学校高三英语上学期期中考试试题及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项ASan Francisco Bay Area is a great place if you're a sports fan as you'll find several events all year round and plenty of team pride. If you are anywhere close to the area during a game,these fantastic sports events are here for you.San Francisco Giants BaseballThe San Francisco Giants baseball team plays in SF at Oracle Park. This is a fun ballpark because it's always packed with great energy and offers views of the bay. It's one of the most popular San Francisco sports events. The Giants are part of the National League West Division. Since their arrival here in 1958,they have been World Series Champions three times.Golden State Warriors BasketballThe fan base of the Golden State Warriors distributes the whole San Francisco Bay Area as this region's only NBA team.Their regular season runs from late October through mid-April, and all home games are played at the Chase Center in San Francisco.In total, the Warriors has won six NBA championships.San Francisco 49ers FootballThe 49ers are San Francisco's NFL team, though they have recently moved to Levi's Stadium in Santa Clara, about an hour south of SF. The football team was named for the prospectors (探矿者) who arrived in the area in 1849 for the Gold Rush. They’ve won 5 Super Bowl championships, all between 1981 and 1994.San Jose Sharks HockeyThe San Jose Sharks represent the Bay Area in hockey (冰球).They were founded in 1991 as the only Bay Area team to compete in the NHL. Sharks fans love going to these San Francisco sports events at the SAP Center,which they call the Shark Tank,located about an hour southeast of SF.1.Where can a sports fan have a good view of the area?A.The Oracle Park.B.The Chase Center.C.Levi's Stadium.D.The SAP Center2.Which team has claimed the most titles according to the text?A.The Giants.B.The Golden State Warriors.C.The 49ers.D.The San Jose Sharks.3.Where is the passage probably taken from?A.A book review.B.A news report.C.A science fiction.D.A tourist magazine.BHave you ever been on social media and seen your favorite celebrity talking about a product? These promotions might not be totally random, and are actually seen as a vital part of the marketing process. The question is: How do social media influencers ‘influence’ what you buy?Human desire for status and making friends, combined with our need to belong to a group, makes us receptive to being ‘socially influenced’. Companies often use that desire to have a similar lifestyle to a celebrity we admire to sell or launch a product. So, what do these promotions actually do?Firstly, they can be used to build brand awareness. A social media influencer should have a strong understanding of the platform they operate on, and therefore can create appealing content that not only sticks to the brand image, but sparks their followers’ interests in a product they might never have seen before.Secondly, influencers can improve a company or product’s relationship with their customer base. According to InMoment’s 2018 US Retail CX Trends Report on customer loyalty, 77% of buyers have been brand loyal for more than ten years. This is also true of 60% of millennials. A popular celebrity can target key customers and talk or blog about a product, which can create an instant and lasting bond with them.Lastly, influencers can improve customer buying habits with seemingly ‘unbiased opinions’. We are more likely to respond to ‘peer recommendation’ than traditional ads, meaning the fact we see an influencer as a ‘friend’ can make us less likely to be doubtful about what we are seeing.So, the next time you see a celebrity talking about a product, you might want to consider that this could be a carefully worked-out marketing strategy designed to target your core needs. If you find yourself examining a product you’ve seen on social media, you may well have been influenced.4. Why do companies invite celebrities to launch products?A. Because celebrities can improve the companies’ public images.B. Because consumers like to share similarity with celebrities.C. Because celebrities want to make more money.D. Because consumers can make friends with celebrities.5. According to the passage, which strategy is often used by influencers?A. Setting up operation platforms.B. Sending gifts to customers.C. Improving relationship with the company.D. Taking advantage of their popularity.6. To customers, the recommendations of influencers seem to be ________.A. offensiveB. subjectiveC. objectiveD. misleading7. The passage is mainly about ________.A. how social media make adsB. how social media influence our lifestyleC. how social influencers affect our buyingD. how celebrities earn fameCSome of my earliest memories involve sitting with my dad in his study every evening when he came home from the office. I’d watch as he put his personal items away: his watch, wallet, comb and car keys would always occupy the same spot on the table every time.Dad’s comb was bought when he married Mum. Every evening, he would smile, hand me the comb and say: “Be a good girl and help Daddy clean it, OK?” I was more than happy to do it. This seems amundanetask, but it brought me such joy at that time. I would excitedly turn the tap on, then brush the comb with a used toothbrush as hard as I could. Satisfied that I’d done a good job, I would proudly return the comb to Dad. He would smile at me, and place the comb on top of his wallet.About two years later, Dad started his own business. I started primary school. That was when things started to change. Dad’s business wasn’t doing so well, and he didn’t come home as much as he used to. Over the years, I stopped waiting for him to come home.Today, I’ve graduated from college and Dad’s business are better now. Yet the uncomfortable silence between Dad and me continued. Two days before my birthday last year, Dad came home early and said to me, “Hey, would you like to help me clean my comb?” I looked at him a while, then took the comb and headed to the sink. It’s a new comb. I hadn’t noticed that he’d changed it. I brushed the comb, and it hit me then: why, as a child, helping my dad clean his comb was such a joy.I passed the clean comb back to Dad. This time, I noticed my day has aged. But his smile is still as heartwarming as before. Dad carefully places his comb on top of his wallet. After so many years, I guess some things never change. And for that, I’m glad.8. As a child, the author helped her dad clean his comb happily because ________.A. she was good at cleaning the combB. she thought that she should do that as a good girlC. her dad was home early to spend the evening with herD. the comb was important for her father and her mother9. Which of the following words can best replace the underlined wordmundanein paragraph two?A. importantB. excitingC. unnecessaryD. uninteresting10. When the author said, “It’s a new comb. I hadn’t noticed that he’d changed it.”, she felt ________.A. disappointedB. impatientC. tiredD. sorry11. What’s the best title of the passage?A. Evenings With Dad.B. How to Clean the Comb.C. My Memory with My Dad.D. I Love My Family Members.DI have a memory of being about five years old, picking up a beautiful grilled(烧烤的)cheese sandwich made for me by my hard —working mother and turning it over to see that theother side was burned. Suddenly what I thought was the perfect sandwich was not so perfect. Mom had tried to hide that fact from me. There was no question; I ate it anyway without complaining. However, that moment has stuck in my mind for many years. Now, at the age of 43 as a mother of two children and as a biology professor where I am routinely the "academic mother" of hundreds of students every year,I find that I believe inThe Grilled Cheese Principle.Here is what I mean Making a grilled cheese sandwich is easy right? But when I think of how many burned grilled cheese sandwiches I have eaten, or I have made myself, I realize that most of the grilled cheese sandwiches I have known have had at least one burned side. The thing is that although it is a ly easy thing to make, I can also easily lose focus, and before long the sandwich is burned. For my mother, the first side was usually perfect and the second side got burned due to her being distracted. For me,I have tended to burn the first side,but then I more carefully monitor the second side.Either way,the grilled cheese sandwich suffers because it has not been given the attention it deservesSo, I have learned that even the simplest task deserves my full attention. When I am multi-tasking, I am doing none of the tasks well. And when I allow myself to be distracted, I am not in the present moment — not paying attention to the small details of living or enjoying the processSo now, I believe the best way to make a perfect grilled cheese sandwich is to make only one at a time and give it my full attention.12. How did the writer react to the sandwich with burned side?A. She ate it with some complaintsB. She showed no interest.C. She thought it was still perfectD. She was deeply impressed with it13. What doesThe Grilled Cheese Principlemean?A. Even simple things deserve full attentionB. Losing focus makes the sandwich burnedC. Self-made sandwiches are always burnedD. we should make only one sandwich at a time14. Which of the following can we infer from the passage?A. Everything cannot be done well without full attentionB. Moms always like to lie to kids when they have done something wrongC. We can lose focus more easily when we do easy things.D. Multi-tasking can be an obstacle to the achievement of tasks.15. What does the writer mainly want to tell us?A. Nothing is perfectB. Learn to appreciate the burned sandwichesC. Devote yourself to one thing at a time.D. Never do multi-tasks第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
