2020届山东省实验中学高三英语月考试题及答案解析第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AAre you looking for some new and exciting places to take your kids to? Try some of these places.★Visit art museums.They offer a variety of activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling exhibits, book signings by children's favorite writer, and even musical performances and other arts.★Head to a natural history museum.This is where kids can discover the past from dinosaur(恐龙) models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.★Go to a Youtheater.Look for one in your area offering plays for child and family visitors.Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts Puppet(木偶)making and stage make-up are just a couple of the special offerings you might find.★Tryhands-on science.Visit one of the many hands-on science museums aroundthe country.These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.1.If a child is interested in the universe, he probably will visit _____.A.a YoutheaterB.an art museumC.a hands-on science museumD.a natural history museum2.What does "hands-on science" mean in the last paragraph?A.Science games designed by kids.B.Learning science by doing things.C.A show of kids' science work.D.Reading science books.3.Where does this text probably come from?A.A museum guide.B.A tourist map.C.A science textbook.D.A news report.BIt was once a shoreline buried by enough garbage to make it invisible (看不见的), thus, given the unfortunatenickname "toilet bowl" . Now the Philippines' Manila Bay beach is totally different, compared with a few months ago. It happened so suddenly and extremely that it brought tears to the eyes of the local people.The cleanup started on 27 January, when 5, 000 volunteers descended on Manila Bay to remove over 45 tons (公吨) of garbage, marking the beginning of a nation-wide environmental campaign. But some two months before this great movement began, a quiet revolution was already underway.During the first week of December 2018, Brooklyn- based Bounties Network collectedthree tons of garbage from Manila Bay aver two days through a project that paid a small group of people, mostly fishermen, with a digital currency (数字货币) based on the Ethereum system.For the mostly non-bank -using Filipino fishermen, this was a first-ever experience with a digital currency. It's one that proves decisive in enabling poor communities around the world to take up arms in the fight against humanity's waste.There are signs that this recycling-for-digital payment industry may be just about to take off. Earlier in September 2018, Plastic Bank, a Vancouver -based company powered by IBM technology, also started a similar project. They set up a project in Naga, a town in southern Luzon, the country's largest island, building a collection point to let people exchange plastic and recyclable materials for digital payouts through a system.That both these pioneers have chosen the Philippines as their first location is not surprising considering the country's contribution to ocean waste. A Wall Street Journal study in 2015 revealed that the Philippines make the third-largest amount of plastic waste into global oceans.4. Why did people call Manila Bay beach“toilet bowl” ?A. It looked like a huge bowl.B. There were plenty of toilets.C. It was covered by rubbish.D. People loved the toilets here.5. What does the underlined phrase“descended on”in paragraph 2 mean?A. Completely depended on.B. Suddenly arrived at.C. Occasionally decreased to.D. Gradually disappeared from.6. What made poor communities willing to fight against waste?A. The benefits to their homeland.B. The desire to make a difference.C. The chance to escape ocean pollution.D. The experience with a digital currency.7. What is the best title for the text?A. Online system helps endocean pollution.B. Manila Bay beach is suddenly removed.C. Plastic Bank is powerful in recycling waste.D. Philippines make a great amount of waste.CFaming is a tradition among many in South Dakota, one that is not always easy to keep in the family. But one family has survived four generations and hopes to continue long into the future. The year was 1933 when Ed VanderWal's father first stepped onto the farm. Now 80 years later, Ed carries the passion(热情) his father gave him for farming every daywhile working the fields on the family farm in Volga.“Well, I was in the first grade when my dad moved here to this farm and I grew up on the farm. And that's what I was interested in doing more,” Ed said. But that love of working the land didn't stop with Ed. He's passed it down to his six sons. Some of them run farms of their own now, but two of them, Scott and David, still work side by side with their dad every day.Some people might worry that working sun up to sun down with family seven days a week would lead to a few family spats(争吵). But for the VanderWals, the constant time together works just fine.“When families work together on a farm, it's a challenge at times getting along. Everyone has to pull their weight and do their share. And that, of course, transfers from one generation to the next,” Scott said.And while they all get along like any family, with good days and bad, it's tradition that keeps each generation teaching the next.“But we taught them to work with animals at a young age, like most farmers do. So it's nice to be able to pass that tradition onto the next generation,” Scott said.The youngest generation of the VanderWals, Ed's three grandsons and a granddaughter, all started learning farming techniques at a young age.8. Why did Ed VanderWal devote himself to the farm?A. Because he grew up on the farm.B. Because he was affected by his father.C Because he could do nothing but work on the farm.D. Because he wanted to set a good example for his sons.9. What can we know from Paragraph 2?A. Managing a farm is a real challenge.B. Ed has divided his farms into six parts.C. Ed taught his sons how to work on farms.D. Scott and David own their own farms now.10. What can be inferred from the passage?A. The VariderWals have strict family rules.B. Ed's tradition has great effect on the local.C. Ed's grandchildren will drop out of school.D. Ed's farms have no lack of successors (继承者).11. What's the best title of the passage?A. A Faming Family.B. A Successful Farmer.C. The Agricultural 'Tradition.D. The Agricultural Generation.DFor as long as I can remember, my body and I have shared a relationship of discontent. Growing up, I was skinnier than the other kids and at five I was told I wasn't attractive and that I must put on some weight. But no matter how much I ate, I stayed thin for years until adolescence. Then I started putting on weight almost immediately. I remember feeling happy as I began to fill out. However, my joy didn't last long.I was thirteen when I was first called fat. Friends and neighbours would make jokes on my big size. As I entered my late teens, I had completely lost confidence in my body and, subsequently, in myself. Having failed to live up to conventional beauty standards, I was convinced that if I wanted to be loved, I needed to offer more, doing anything to please everyone around.I entered adulthood thinking I wasn't “enough”—an idea that was seeded not only by the fact that “skinny” is celebrated, but also by the language associated with accounts of losing weight—selfimprovement, discipline—all virtues. Being fat quickly categorizes you as lazy and undisciplined. Consumed by thoughts of the way my body looked, I didn't notice the other ways my body needed attention. I failed to realize, for example, that my period was much heavier and more painful than ever before. Actually I developed a rare disease and later I had two surgeries.I was always made to feel that my weight was the root of a lot of problems in my life; I have learnt this is not true. After a lot of selfreflection and some professional help, I realized I never learnt to like myself. While two decades of selfhatred cannot be undone overnight, I have taken first steps to acceptance.I am now much lighter than before, in body and mind. There are days I find voices on social media saying I amtoo fat to be loved or to be worthy, but I am learning not to focus on that thought for long. As long as I like myself, just the way I am, opinions at the end of the day are just water off a duck's back.12. What can we learn about the author from the first two paragraphs?A. She could change her weight at will.B. She had different beauty standards from others.C. She tried to love others to build her confidence.D. She was greatly influenced by others' opinions.13. Why did the author think she wasn't “enough”?A. She was poorly disciplined.B. She failed to celebrate “skinny”.C. She was labelled as lazy for her weight.D. She put on more weight after entering adulthood.14. What caused the author to make a change?A. Her lighter body.B. A troublesome illness.C. Popular beauty standards.D. Others' critical comments.15. What is the best title for the text?A. Beauty matters.B. Opinions vary.C. Worth your weight.D. Beyond your limits.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。

AFour things that you can't miss in Macao.Macao Tower AJ Hackett Bungee JumpThe Macao Tower, 338 meters tall, is the world's 10th highest tower, with a variety of activities, such as gambling, eating and entertainment. One of the acclaimed activities is the bungee jump. The AJ Hackett Macao Tower Bungee Jump is 233 meters high, making it the highest commercial bungee jump in the world. Raise your arms and off you go! If you are not daring enough to jump that height, you can try the skywalk on the 57th floor ---it's still remarkable.Grabbing a traditional Portuguese dinnerMacao was colonized by Portugal before 1999. As a result, Portuguese culture is deeply immersed into many comers of Macao. Many Portuguese settled and opened Portuguese restaurants in the special administrative region, but the flavor is more adaptable to Chinese people. Marking at the Ruins of St. PaulThe Ruins of St. Paul is the signature landmark of Macao. The ruins consist of the St.Paul'sCollege and the Church of St. Paul, built in 1583. However, after three intense fires in 1595, 1601 and 1835, the church was seriously damaged. It is beyond belief that after the vigorous cycles of rebuilding and fires, the huge surface and the front stairway remain unburned.Visiting a museumMacao, as a tiny city with only an area of 30.5 square kilometers, has 23 eye-catching museums. Due to its unique history, both Eastern and Western historical sites can be found. Many of them are preserved for cultural heritage, tourist spots or museums, such as the Grand Prix Museum, Maritime Museum and Wine Museum.1. Which activity will be popular with adventurous visitors?A. Going Bungee Jumping.B. Grabbing a traditional Portuguese dinner.C. Marking at the Ruins of St. Paul.D. Visiting a museum.2. What is incredible about the Ruins of St. Paul?A. It has a unique culture.B. It serves as a symbol of Macao.C. It partly stays undamaged after fierce fires.D. It is a combination of a college and a church.3. What do "'Grabbing a traditional Portuguese dinner" and "Visiting a museum" have in common?A. Taking a selfie in it.B. Finding historical sites.C. Enjoying a breathtaking experience.D. Feeling both eastern and western cultures.BI was seven when I first questioned my imagination. I remember watching the first Harry Potter film and my friend was complaining that the characters weren't how she imagined them to be. I couldn't understand what she meant because, in my mind, they had never been images at all, just concepts. When l shut my eyes, I see nothing. I have no visual imagination.I thought everyone's minds worked this way until about two years ago, when I came acrossatext about aphantasia, a condition where you lack a functioning mind's eye. I was 23, and it blew my mind to learn that others could visualize things. It was clear I had aphantasia, too, and a lot of things started to make more sense. For me, imagination had always been impossible. If someone asked me to close my eyes and picture myself by the sea, I would see nothing.I am currently studying for a PhD in biology at college. A good little test for me is drawing. I can copy things almost like for like if they are in front of me, but if I were to draw from my imagination it would look terrible. It doesn't mean you cannot be creative; you just have to adapt. Regardless of how many times I read a technique, it didn't make sense. But when I came to do it in the lab, I understood it immediately. If you have a visual imagination, you can look at a diagram and it triggers your memory; but I learn by repetition or physically doing something.I'd love to experience life with a mind's eye. I think it'd be cool and beneficial to imagine things so vividly. If you offered me a day with a visual imagination, I'd be excited. I think it'd be so brilliant that I wouldn't want to give it back.4. After watching the first Harry Potter film, the author _____ .A. misunderstood what her friend saidB. became a huge fan of the Harry Potter filmC. found it impossible to picture its characters in her mindD. complained its characters different from what she imagined5. How did the author know she had aphantasia?A. Her friend told her the fact.B. She read about aphantasia.C. She had a medical examination.D. Her life experience made it clear.6. What can we learn about the author?A. She lacks creativity.B. She always draws terribly.C. She learns by hands-on practice.D. She gets benefit from techniques.7. What is the author's attitude towards her disability?A. Uncertain.B. Uncaring.C. Upset.D. Positive.CFor years, the U.S. has experienced a shortage of registered nurses. The Bureau of Labor Statistics projects that while the number of nurses will increase by 19 percent by 2022, demand will grow faster than supply, and that there will be over one million unfilled nursing jobs by then.So what's the solution? Robots.Japan is ahead of the curve when it comes to this trend. Toyohashi University of Technology has developed Terapio, a robotic medical cart that can make hospital rounds, deliver medications and other items. It follows a specific individual, such as a doctor or nurse, who can use it to record and access patient data. This type of robot will likely be one of the first to be implemented in hospitals because ithas fairly minimal patient contact.A robot's appearance affects its ability to successfully interact with humans, which is why the RIKEN-TRI Collaboration Center for Human-Interactive Robot Research decided to develop a robotic nurse called Actroid F. It is so human-like that some patients may not know the difference. This conversational robot companion has cameras in its eyes, which allow it to track patients and use appropriate facial expressions and body language in its interactions. During a month-long hospital trial, researchers asked 70 patients how they felt being around the robot and "only three or four said they didn't like having it around."It's important to note that robotic nurses don't decide courses of treatment or make diagnoses, though robot doctors and surgeons may not be far off. Instead, they perform routine and laborious tasks, freeing nurses up to attend to patients with immediate needs. This is one industry where it seems the interaction of robots will lead to collaboration, not replacement.8. What does the author say about Japan?A. It ranks top in future robotics technology.B. It takes the lead in offering robotic nursing.C. It is in desperate need of registered nurses.D. It provides the best medication for the elderly.9. Which of the following best explains “implemented'' underlined in Paragraph 3?A. Cancelled.B. Constructed.C. Improved.D. Applied.10. What do we know about the robot Actroid F?A. It has no difference from a human nurse.B. It gets favorable remarks from all the patients.C. It interacts with patients like a human companion.D. It uses body language even more effectively than words.11. What can be inferred from the last paragraph?A. Cooperation will not be replaced.B. Nurses will still play their roles.C. The robotics industry will be promising.D. Robots can meet patients' immediate needs.DWhy should most of us hate spiders when we know deeply how much good they do? Is it because they somehow seem so alien? After all, what other land creatures on earth have eight legs? What other creatures spin silk webs in which to catch and wrap their prey to preserve it for the future, much as we put food in the fridge to eat later? I do not personally suffer from arachnophobia, the name given to an abnormal fear of spiders, but I can't say that I like the little beasts. However, some peopledo, and they actually keep them as pets!There is a wide variety of spiders in the world. In fact it has been estimated that there are some 35,000 species——from little "money spiders" that live in your back garden, to the "black widow spider", and the “tarantula” ,the spider that is now sometimes kept as a pet.A tarantula can be any one of a large hairy spiders family and there are about 800 species of them. While experts can tell the difference between species at a glance, most are usually described in reference books as “rather slowly" with “a strong bite which may be poisonous”. They are covered with hairs which can cause a rash (皮疹)if they are handled.No one has calculated the number of human deaths caused by a bite from a tarantula perhaps because it has never happened, or happened so rarely, and indeed a tarantula will do no harm to anyone if handled correctly. Their disgusting image cannot belie their gentle nature but experts tell us not to handle a tarantula without expert advice.Tarantulas are popular as pets and it requires very little space to maintain them in excellent condition. They should be kept singly in a glass container, which need not be very large but should have a layer of stones in the bottom. They feed on insects, and while young tarantulas eat twice a week, adults will often eat no more than once every 10 days.You might like the idea of keeping a tarantula, but personally I am content with just watching them at a distance.12. According to the text, why do most people dislike spiders?A. They are abnormal beasts.B. They take food from fridges.C. They have unpleasant appearance.D. They make people suffer from arachnophobia.13. What do we know about the tarantula?A. It must be kept in groups.B. It feeds on poisonous insects.C. It doesn't belong to hairy spiders.D. It has mild nature if handled properly.14. What does the underlined word “it” in Paragraph 4 refer to?A. The death caused by a tarantula.B. The number of human deaths.C. The bite from a tarantula.D. The rash caused by hairs.15. What's the best title for the text?A. Never judge a book by its cover.B. Nothing seek, nothing find.C. No sweet without sweat.D. Once bitten, twice shy.第二节(共5小题;每小题2.5分,满分12.5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。

A hookah system is a system of providing air from the surface to divers down below. Cage divers breathe by using a regulator connected to an air hose.Is SharkDiving Dangerous?Yes. You could get sunburnt. You could hit your head on the top bunk getting out of bed. You could fall overboard. As for a shark attack, according to the International Shark Attack File, you are far more likely to be killed by a dog or a deer.Pricing & DetailsOne day Cage Diver Adventure $ 875Our expert shark diver team will accompany you to the best viewing areas within the Marine Sanctuary. There, we'll drop our cage and prepare to provide you with a view you'll never forget.No dive experience is necessary. Our cages sit just below the surface. You'll be able to breathe comfortably from your snorkel or air hose while you move about the cage, taking photos and having fun.Top Shark Adventure $ 375If you want to see great white sharks but prefer them a little further away, we offer great top-side shark viewing from our observation deck(甲板). Help scan the horizon for fins and watch for sharks attacking their prey(猎物).Important NoteThere's No Shark GuaranteeAlthough we go to the best places at the best time of year, we cannot guarantee you'll see sharks. We've been very successful in past shark seasons and expect another incredible year. However, if we see no sharks, there is no refund(退款).1.Which of the following is TRUE about the two adventures?___________.A.Top Shark Adventure makes use of hookah systems.B.Cage Diver Adventure offers you a view of the bottom of the sea.C.Cage Diver Adventure is less interesting than the other.D.Top Shark Adventure is suitable for those worried about danger.2.We can learn from the advertisement that there might be a risk that____________.A.you fail to achieve your purpose of the tripB.you are out of breath deep down in the seaC.you are hurt by a shark while diving thereD.you suffer from lack of skill in shark diving3.It can be inferred from the advertisement that shark diving is____________.A.difficult but excitingB.challenging and tiringC.amazing and enjoyableD.expensive but popularBHave you ever been sad because of failure? Please remember, for quite often achieving what you set out to do is not the most important thing.A boy decided to dig a deep hole behind his house. As he was working, a couple of older boys stopped by to watch. “What are you doing?” asked one of the visitors. “I want to dig a hole all the way through the earth!” the boy answered excitedly. The older boys began to laugh, telling him that digging a hole all the way through the earth was impossible. After a while, the boy picked up a jar. He showed it to the visitors. It was full of all kinds of stones and insects. Then he said calmly and confidently, “Maybe I can’t finish digging all the way through the earth, but look at what I’ve found during this period!”Theboy’s goal was far too difficult, but it did cause him to go on. And that is what a goal is for-to cause us to move in the direction we have chosen, in other words, to cause us to keep working!Not every goal will be fully achieved. Not every job will endup with a success. Not every dream will come true. But when you fall short of your aim, maybe you can say, “Yes, but look at what I’ve found along the way! There are so many wonderful things having come into my life because I tried to do something!” It is in the digging that life is lived. It is the unexpected joy on the journey that really makes sense.4. The older boys laughed at the boy because he was thought to be______.A. braveB. impoliteC. foolishD. warm-hearted5. Why did the boy show the jar to the older boys?A. To drive them away.B. To show what he had found in digging.C. To show how beautiful the jar was.D. To attract them to join him in the work.6. What can be learnt from the fourth paragraph of the text?A. No dream can come true.B. All work will end successfully.C. Goals shouldn’t be set too high.D. Goals will make us work harder.7. The best title for the text should be______.A. A Boy Dug a HoleB. Joy in the JourneyC. No Pain, No GainsD. Failure Is the Mother of SuccessCOver the years, NASA has successfully sent several rovers (飞行器) to Mars. While the science laboratories continue to provide important information on the Red Planet, they keep the space exploration rovers staying closeto the original landing place.To get a more comprehensive (详尽的) view of Mars, the US Space Agency plans to make a small test helicopter with the Mars 2020 Rover, which will be sent off in July 2020.The football-sized “marscopter” weighs about four pounds.It can fly at about ten times the speed of helicopters on Earth. The light weight and fast speed are important for the helicopter to be able to fly in the thin Mars atmosphere, which is about just one percent of that of Earth. “To make it fly in that thin Mars atmosphere, we had to make everything ready, and make it as light as possible while being as strong and powerful as it can possibly be. “Mimi Aung, Mars helicopter project manager, said in a meeting.Upon landing on the Red Planet, the Mars 2020 Rover will find a proper location to send of the helicopter. The helicopter will start with a short climb, no higher than 10 feet, and hover (盘旋) for just 30 seconds before landing back on the Mars surface. If all goes well, five more flights of longer distances, for 90 seconds each, will be conducted over the next 30 days. The short journeys will be recorded by a small camera and sent back to the scientists on Earth.If the plan goes on well, the first helicopter to fly in another world, will open up a whole new way to exploreMars. The Mars helicopter's first flight will be a great invention. For those of us whose research is about flight, that would be a wonderful, historic moment.8. To fly in thin Mars atmosphere,we should make the helicopter_______.A. strong and heavyB. heavy and fastC. light and fastD. strong and slow9. How many times will the helicopter fly?A. Three timesB. Four timesC. Five timesD. Six times10. What can we learn from the last paragraph?A. It’s interesting to fly in another world.B. I' s important to fly in another world.C. The plan to fly the helicopter goes on well.D. The helicopters first flight is successful.11. What may be the best title for the passage?A. To send a helicopter to Mars in 2020B. To send a rover to Mars in 2020C. To live in the thin Mars atmosphereD. To send back records to scientistsDThe Jewish(犹太人)family-had-just finished supper and the woman had placed the dishes in the sink.The kitchen was quite damp and even gloomier than in the main room.It was their third apartment since the start of the war,they had abandoned the other two in a hurry.The woman came back into the room and sat down again at the table.The 3-year-old boy sat with his back straight,his eyes fixed on his father,but it was obvious that he was so sleepy that he could barely sit up.The man was smoking a cigarette.His eyes were blood-shot and he kept blinking in a funny way.This blinking had begun soon after they fled the second apartment.It was late,past ten o'clock and they could have gone to sleep,but first they had to play the game that they had been playing every day for two weeks.Even though the man tried his best and he moved very quickly,the fault was his and not the child's.The boy was.marvelous.Seeing his father put out his cigarette,he opened his blue eyes even wider.The woman,who didn't actually take part in the game, stroked the boy's hair.“We'll play the key game just one more time only today.Isn't that right?"she asked her husband.He didn't answer because he was not sure.They were still two or three minutes off.He arose and walked towards the bathroom door.Then the woman called out softly,“Ding-dong."At the sound of the bell ringing somusically from his mother's lips,the boy jumped up from his chair and ran to the front door,which was separated from the main room by a narrow corridor.“Who's there?"he asked.The woman,remaining in her chair,shut her eyes tight as if feeling a sudden, sharp pain.“I'l1 open up in a minute,I'm just looking for the keys,"the child called out. Then he ran back to the main room,making a lot of noise with his feet.He ran in circles around the table,pulled out one of the sideboard drawers,and slammed it shut.“Just a minute,I can't find them,I don't know where Mama put them,"he yelled,then dragged the chair across the room,climbed onto it,and reached up to the top of the shelf.“I found them!”he shouted triumphantly.Then he got down from the chair, pushed it back to the table,and calmly walked to the door and opened it.“Shut the door,darling,"the woman said softly."You were perfect.”The child didn't hear what she said.He stood in the middle of the room,staring at the closed bathroom door.“Shut the door, the woman repeated in a tired flat voice.Every evening she repeated the same words,and every evening he stared at the closed bathroom door.At last it opened.The man was pale and his clothes were streaked with lime and dust.He stood there,eyes blinking in that funny way.“Well?How did it go?"asked the woman.“I still need more time.He has to look for them longer.I slip in sideways allright,but then...It's so tight in there that when I turn...And he's got to make more noise-he should stamp his feet louder."The child didn't take his eyes off him.“Say something to him,"the woman whispered."You did a good job,little one,"he said mechanically.“That's right,”the woman said,“you're really doing a wonderful job,darling. You act just like a grown-up.And you do know that if someone should really ring the doorbell when Mama is at work,everything will depend on you?And what will you say when they ask you about your parents?”“Mama's at work.”“And Papa?"He was silent.“And Papa?"the man screamed in terror.The child turned pale.“And Papa?”the man repeated more calmly.“He's dead,”"the child answered and threw himself at his father,who was standing right beside him,but already long dead to the people who would really ring the bell.12. What does the underlined sentence in Para.5 mean?A. The family needed to practise the game for another 2 or 3 minutes.B. There was still 2 or 3 minutes left before someone knocked at the door.C. They would become too sleepy to play the game 2 or 3 minutes later.D. The father needed 2 or 3 more minutes before the kid opened the door.13.

Because he was too little and just couldn't control his footsteps.C. Because he was too anxious to find the key to open the door with.D. Because he met many barriers on his way to where the key was.14. In Para.12,why did the mother repeat“shut the door”in a tired,flat voice, instead of the previous soft one?A. She was angry because her son didn't close the door as he had been told to.B She felt anxious because she knew her husband would be annoyed at the boy again.C. She was disappointed because the boy's movement betrayed again where her husband was.D. She was impatient because she was asked to repeat these words again and again every evening.15.

2020年山东省实验中学高三英语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ASwimming Holes in AmericaIn America, these secret swimming holes are hidden and hard to reach but well worth the adventure.Cummins FallsLooking for the best place to escape the summer heat in the heartland of America? For more than 100 years, Cummins Falls, a scenic,75-foot waterfall located in Jackson County, TN, has been a treasure for Tennessee natives. But now, the secret is out! Although it’s a bit tough to get to, once in the park, the mountains and river provide unmatched beauty on your way to taking a swim in Tennessee's eighth-largest waterfall.Sliding RockA popular place to cool off during those hot North Carolina summers, Sliding Rock waterfall is located in the Pisgah National Forest in Transylvania County. A flattened rock about 60 feet lies in a nearly 7-foot-deep pool at the bottom, making this natural waterslide a great place to visit with people of all ages.Mooney FallsIt is the tallest water feature in the Grand Canyon, rising 190 feet above the surface. Named after an explorer in the 1800s, Mooney Falls is accessible only by crawling(爬)through 2 underground passages and then climbing down a sheer cliff(峭壁)face with just a couple of chains to hold on to. Although it is tough to get to, the view and the cool alone make it worth the trip.Lihue EstateA private swimming hole at the old Lihue Sugar Farm on Kauai, HI, was changed into an inner-tube water ride by Kauai Backcountry Adventures in 2003 and opened to adults. The waters for this 2.5-mile journey, which come from near the top of Mount Waialeale—one of the wettest spots in the world—are channeled through ditches(沟渠)that were hand-dug by farm workers over a century ago.1. Which hole may be the favourable destination for families?A. Lihue Estate.B. Sliding Rock.C. Mooney Falls.D. Cummins Falls.2. What can we learn about Mooney Falls from the text?A. It wasfound by an explorer.B. It was hand-dug in the 1800s.C. It is dangerous to arrive there.D. It is the tallest fall in the world.3. What is special about Lihue Estate?A. It is man-made.B. It is a private area.C. Its water is from underground.D. It lies on the top of Mount WaialealeBNostalgia (怀旧) has become increasingly common in our current climate of accelerated, unexpected change. More and more Americans are turning back with longing towhat feels like simpler, sweeter times. They collect cassette tapes, manual typewriters even decades-old video games.Is it a mistake to get too obsessed with the past? Some psychologists warn that too much devotion to the so-called good old days is an escape from reality; it can indicate loneliness or that a person is having a difficult time coping in the present. Psychologist Stephanie Coontz argues that nostalgia distracts us from addressing the problems of modern life and contribute to anxiety, depression , insomnia etc.But new studies suggest that a modest dose of nostalgia is not only harmless, but actually beneficial. They suggest it helps strengthen our sense of identity and makes us feel more optimistic and inspired. It is also a tool for self — discovery and memories are a psychological immune response that is triggered when you want to take a break from negativity. Interestingly, those happy memories can be particularly beneficial both to kids in their teens and to society's elders. Recalling our childhood reminds us of “the times when we were accepted and loved unconditionally," says Krystine Batcho, a psychologist. "That is such a powerfully comforting phenomenon, knowing that there was a time in life when we didn't have to earn our love." Nostalgia can transform even the most ordinary past into legends which warms the heart and the body. Let's not forget that nostalgia has been a source of inspiration to innumerable American writers. Mark Twain recalled his boyhood, writing, "after all these years, I can picture that old time to myself now, just as it was then:The white town drowsing in the sunshine of a summer's morning."So go ahead, daydream a little about your best childhood friend, your first car, a long - gone family pct. As Dr. Sedikidessays,"Nostalgia is ly central to human experience. "But at the same time, keep these words of wisdom from the great inventor Charles Kettering in mind as well:"You can't have a better tomorrow if you are thinking about yesterday all the time. "34. What did some psychologists in paragraph 2 probably agree?A. Nostalgia will cause some mental problems.B. Nostalgia makes us devoted to the good old days.C. Nostalgia shows you are trying to get rid of loneliness.D. Nostalgia helps us cope with the difficult time we are going through.5. There are many benefits of nostalgia except ________A. It can enable us to know ourselves better.B. It can bring us some comfort when we recall.C. We are likely to gain attention if we recall the happy childhood.D. We can sometimes break away from negativity with happy memories.6. What will be talked about in the following paragraph?A. The bad influence of too much devotion to nostalgia.B. The reasons why we should avoid nostalgia.C. The bad memories that always stick around you.D. The great changes nostalgia will bring to you.7. What's the best title of the passage?A. We all have a soft spot for nostalgia.B. Nostalgia is actually good for you.C. Don't be carried away by nostalgia.D. There are many times when we like to recall.CTwenty years ago, I became involved in pet therapy(疗法) work with our Angel. As she matured and went through professional training, we realized that she would be good at this new job.Angel is ten now and works every week. She visits two hospitals providing day care for the elderly, and our library’s PAWS forReadingprogram. At the library, six to ten dogs lie on the floor, and the kids pick a book to read to a dog. After they finish, they get a card with the dog’s picture and history. Angel also helps out at a special-needs camp. She is so popular that everywhere we go people recognize her, especially the kids she has worked with.We have seen some very special things through our pet therapy work. I brought Angel to our local hospital to visit a woman who was completely unable to move the right side of her body from a stroke(中风). One day, my husband, Jack, got Angel up into a chair next to the woman’s bed, asking her if she wanted to give Angel a treat. She nodded. Angel gently took the treat. Then the woman raised her right hand and started petting Angel. Her friend couldn’t believe her eyes.After that, every time we saw the woman, she lifted her left hand. We’d tell her she had to use her right hand, and she would. Next, you’ll fall in love with this woman’s story of rearing her own Angel later in her family and why she calls it the best decision she ever made.8. Who is Angel?A. A pet trainer.B. A hospitalC. A therapy dog.D. The author’s kid.9. What does Angel usually do?A. Save seriously ill people.B. Pay visits to kids in hospital.C. Protect the elderly in their homes.D. Help children at a special camp.10. Why was the woman’s friend astonished?A The woman moved her right hand.B. The woman treated Angel.C. Angel helped the woman recover.D. Angel got along with the woman.11. What does the underlined word “rearing” in the last paragraph mean?A. Accompanying.B. Raising.C. Assisting.D. Training.DThe Rise of Voice TechnologyVoice technology has come a long way. Just a few years ago, it would have been unusable. But now, those who follow the technology know that it has got considerably better.Writing with your voice raises several interesting questions. How difficult is it actually? Human speech involves a lot more starting and stopping with errors and the need for repairing broken sentences than you may think. Even gifted speakers make mistakes. To turn the spoken word into reasonable writing requires lots of planning. You’ll need some kinds of notes or other organisers to make it work.Another question turning speech into writing raises is the style. How would writing make the change that people speak their writing rather than type? Chances are that it would come up with many more short sentences and more concrete language, which is good. It would probably also rely on prepared phrases a lot more often,which is not available when you are speaking quickly.To confirm this, a column was not written, but dictated (听写). It was composed from brief notes written down for structure only, and it was edited for length, with all of the original errors kept in. Here were the results. The first was that the literal accuracy was extremely high. There weren’t many cases wherethe software had heard one word incorrectly and written down another. But the other result was that the readability of this column was rather bad. Obviously, the blame is not with the technology at all, which turns out to be rather good. Speaking into writing relies on a better human brain than the one we currently possess. Writing is hard. There’s a reason it can’t be done at the speed of speech, in real time.To clarify the matter, this time paragraph breaks were added after the whole writing. Punctuations (标点) had to be spoken aloud, and after a full stop, the first word in the new sentence was capitalized automatically. Some minor punctuation marks were added to make it clearer. To improve accuracy, people “trained” the software beforehand, reading a prewritten passage aloud. Actually it turns out to be more effective. All of these ensure the satisfactory completion of turning speech into writing.Language is the most important tool for human interaction, and voice is one beautiful part of language. With the maturity of modern technology, it has given birth to a great change in the human-computer voice interaction.12. According to the passage, which helps to turn speech into writing in terms of style?A. There is careful planning in advance.B. Errors and broken sentences are avoided.C. People type words as fast as they say them.D. The writing contains more prepared phrases.13. To achieve better results, the author mentions some changes for ______.A. processing errors in a column.B. adding minor punctuation marks.C. increasing the number of brief notes.D. integrating short paragraphs in writing.14. The author suggests that ______.A. human brains are responsible for poor dictated writing.B. writing with voice promises to improve the quality of writing.C. writing is an unnatural act that can hardly be learned and improved.D. technology has a long way to go in the human-computer voice interaction.15. What is the passage mainly about?A. Why people fully intend to turn speech into writing.B. What role voice technology plays in improving readability.C. Where the human-computer voice interaction is at an advantage.D. How voice technology enables the change from speech into writing.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。

材料二:
网络文学,作为改革开放带来的文化成果,于20世纪90年代随着互联网进入中国而诞生。作为一种大众文字样式,网络文学在诞生之初,从技术上实现了普通文学青年的写作零准入,中时打破了传统文学通过印刷出版的高门槛,情感爆发力、创作想象力空前高涨,大批玄幻、仙侠、科幻、都市等类型作品纷纷登场,并得以迅速发展壮大。同时,在内容表现和手法运用上,网络作者自觉、自发、自愿地接续了中华优秀传统文化和西方文学经典的脉络,大量优秀作品随之产生。经过二十几年的发展,网络文学一路走来,逐渐进入主流视野,不断迈向经典化、精品化。
时至今日,越来越多的作者、读者加入网络文学中来,这与网络文学的本体特征和属性有着内在的关联。网络小说作为互联网时代的产物,作为大众文化的果实,作为以青年为主体的广大作者抒发情感和想象的载体,也作为以青年为主体的广大读者寄予情感和梦想的阵地,随科技更新迭代,从PC到移动,从文字到IP,以文字为源头的主体性从没改变。创作与阅读的主体关系不仅互为表里,也伴随着网络文学的发展进程,成为以青年为主体的娱乐化的必然诉求。网络文学成为当代中国重要的文化现象,同时也成为创作与阅读双方的日常,陪伴着他们成长。
网络文学突出的社会性,要求重建现实主义传统。数字媒介前所未有地加强了文学的社会性。网络文学成为一种社会形式,它的生产、运营与阅读模式具有突出的社会性特征。写作与阅读不再是传统文学的个人行为,而是社会性、群体性事件。与此同时,网络文学与日常生活具有密切的相关性,并通过影视、游戏、动漫等衍生品进行了广泛地传播,改造着参与者的日常生活,发挥着重要的社会与文化功能。由于网络文学的过度商业化,部分网络文学作品呈现出利己主义、拜金主义等不良思想倾向。面对这种情况,显然需要重新强调现实主义传统的思想性、倾向性,强调文学的教育作用与社会责任意识,要求网络文学传递社会正能量,提升整个社会的人文精神。这样既有利于中国年轻一代价值观的塑造,也有利于网络文学的海外传播。

一、现代文阅读
网络文学的热血幻想不仅是一个“白日梦”,而且是基于人类社会的终极愿望,携带着人类文化基因密码,合乎人类情感的发生发展。如果说网络文学是专指在网络上发表并传播的一种带有大众文化属性的外在表达,那么,热血幻想就是网络文学内在的本体特征,也是网络文学创作的主体标识。
(摘编自《凸显本体特征 深植现实观照——二零应该重新得到重视与强调,被赋予新的生命力。
在中国作协发布的“2018中国网络小说排行榜”上,现实类题材作品占据了一半的席位,而有的文学网站“现实频道”上线不到一年,就有4万多部现实题材作品。与此同时,传统的幻想类题材也开始生活化,被称为“生活流”。这种现实题材的创作倾向既是网络文学发展20年之后自我转型、突破瓶颈、扩大创作空间的需要,也与网络社会由早期的虚拟空间日渐转向虚拟与现实的互渗相关,这在客观上为现实主义传统的回归与重建奠定了基础。
(摘编自《开启新媒介现实主义 切近网络文学发展实际》)
1.下列对材料相关内容的理解和分析,正确的一项是( )
A.网络小说尽管依赖新兴的互联网而产生、发展,但从整体上说,在题材、创作方式等方面还是和传统通俗文学一致的。
B.近20多年来中国网络文学数量更加庞大,原创性大大提高,质量大幅提高,优秀作家作品大都聚集于通俗文学领城。
在中国整个文化市场中,网络文学行业发展是超前的,广度大,种类丰富,内容质量过硬。但一个国家的文化实力不是单一文艺领域就能造就的,它是各行各业协作的结果。目前为止,除了孙悟空这样的传统经典形象之外,我们还没有一个全新创作的、在全球市场都广受欢迎的当代文化符号。如果我们能在网络文学作品中发掘出这样的资源,再通过下游改编把它放大,打造出一个代表新时代中国的文化符号,才算是中国流行文化真正的成功。
阅读下面的文字,完成下面小题。
材料一:
整体而言,网络小说的典型形态和传统通俗文学是一脉相承的。互联网的作用体现在使小说创作者与读者之间建立新的联系,读者通过互联网推动创作者开发出更多新题材、新创作方式和新内容。创作者们在同一平台上相互竞争,也会推动内容进化,使得内容走向“多元化”。可以说,中国网络小说在全球都是走在前列的,对中国当代文化发展产生了很强的推动力。
互联网传播和反馈速度更快,交流更直接。用户通过互联网贴出小说,瞬间就能到达读者手中。作家可以快速调整内容,写作水平也会快速提高。很多小说开头很一般,甚至漏洞百出,但写了几个月之后,作品渐入佳境,让人无法割舍。互联网对创作的提升帮助非常大。
网络文学的面貌几年就会发生一次巨大变化,不断推陈出新。近20多年来,网络文学有三个最直观的变化:一是数量更加庞大。最早的时候,论坛上前一晚所有小说的更新内容,早上起来花一两个小时就可以看完。现在网络小说每天的更新量之大,无论你怎么翻页都翻不完。二是从模仿到原创。当时大部分内容,10部有9部是玄幻类作品,题材比较单一,而现在仅大类就有200多个,下面小流派更多,原创性大大提高。三是质量大幅提高。当时作品大多模仿痕迹很重,语言和构思也比较稚嫩。现在很多作家文笔老练。今天,网络小说可以说聚集了通俗文学领域的很多优秀作家作品。
在日本、韩国和东南亚各国,我们的网络小说已经大量进入,翻译后不存在接受障碍,国内的热门作品,在国外受欢迎程度也很高。在欧美,近两年也开始出现翻译中国网络小说的趋势,截至2019年初已翻译100多部,起点国际上线后,有了专业译者组的帮助,迄今翻译500多部。这是我们以前很难想象的,尤其是我们网络小说都很长,几百万字、上千万字的都有。有国外爱好者花如此大的精力和成本主动翻译,说明我们的网络文学有内容品质优势,成功走出去本身很能说明问题。
