2019-2020学年大连市第三十四中学高三英语二模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AAs the MOOC craze continues to explode, anyone interested in taking an online course faces a tricky question: Which course to take? Here are five aspects that you should consider before you start.(1)What is your learning style?Many MOOCs are video-based. Other courses use presentation formats. Some also require participation in group work. If you want to stay motivated during your course, think about how you enjoy learning.Are you a visual learner, preferring to use images to understand a topic? If so, a video-based course will work well for you. If you are a verbal learner who gains new information by speaking and writing, try a text-based course with lots of note-taking. Social learners, meanwhile, will thrive in forum discussions and project-based assessment.(2)Are you ready to become a full-time student?Be realistic about the time that you can commit to your online studies. Participating in an online course can take as much time and commitment as a class-based program.

Is the course aimed at beginners or advanced learners? Why do you need this qualification?(4) Do you need a support group?Some people learn best from seeing how others approach the problem. If you are such as learner, you will need to supplement your online lessons with an in-person support group.(5) What kind of certification will you get?Take time to find out what kind of certification is available upon completion of the course, and how you can prove your learning to others - for example, certificates, transcripts or digital badges.1.

The damage seems to fool the plant into flowering, sometimes up to 30 days earlier than normal.With their hairy appearance and special sounds, bumblebees are hard to miss in gardens all over the world. Their hairy bodies make them excellent pollinators for crops like tomatoes and blueberries. They are among the first bees to appear each year and work a long season.But despite their key role, bumblebees, like many other pollinators have seen their numbers decline suddenly in recent decades. One recent study pointed to climate change, reporting that an increasing number of hot days in Europe andNorth Americawas raising local bumblebees extinction rates.But researchers have now made a discovery about bumblebees that could have something to do with their long term survival. Scientists inSwitzerlandfound that when the bumblebees were out of pollen, they started to bite on the leaves of plants that hadn't yet flowered. They used their mouths to cut clearly-shaped holes in the leaves. But the creatures didn't eat the material or use it in their nests.The damaged plants responded by flowering earlier than normal--in some cases up to 30 days ahead of schedule. Researchers also found that the bee damaged plants flowered 30 days earlier than undamaged plants and 25 days earlier than ones damaged by the scientists.“I think everything that we've found is consistent with the idea that the bumblebees are damaging the plants and that that's an adaptation that brings flowers earlier and that benefits the bees,” said Dr Mark Mescher, one of the authors from ETHZurich.4. How do bumblebees fool plants into flowering earlier?A. By making use of the hot weather.B. By putting the false flowers on the leaves.C. By attacking the leaves of flowerless plants.D. By taking away the pollen from the other flowers.5. What's bumblebees’ key role?A.Making plants flower early.B. Spreading pollen to flowers and plants.C. Sending information about weather change.D. Finding out whether the plant has flowers.6. What has happened to bumblebees in the past the years?A. They are becoming homesick.B. They are not as friendly as before.C. There is a sharp decrease in number.D. They have been busy year by year.7. What's Dr Mark Mescher's attitude towards the behaviour of bumblebees?A. Uncaring.B. Skeptical.C. Tolerant.D. Objective.CTeens who have good, supportive relationships with their teachers enjoy better healthas adults, according to research published by an American research center.“This research suggests that improving students' relationships with teachers could have positive and long-lasting effects beyond just academic success," said Jinho Kim, a professor atKoreaUniversityand author of the study."Itcould also bring about healthimplicationsin the long run.”Previous research has suggested that teens' social relationships might be linked to health outcomes in adulthood. However, it is not clear whether the link between teen relationships and lifetime health is causal（因果的）-it could be that other factors, such as different family backgrounds, might contribute to both relationship problems in adolescence and to poor health in adulthood. Also, most research has focused on teens' relationships with their peers（同龄人）, rather than on their relationships with teachers.To explore those questions further, Kim analyzed data on nearly 20,000 participants from the Add Health study, a national study in theU.S.that followed participants from seventh grade into early adulthood. The participant pool included more than 3,400 pairs of siblings（兄弟姐妹）. As teens, participants answered questions, like “How often have you had trouble getting along with other students and your teachers?" As adults, participants were asked about their physical and mental health.Kim found that participants who had reported better relationships with both their peers and teachers in middle and high school also reported better physical and mental health in their mid-20s. However, when he controlled for family background by looking at pairs of siblings together, only the link between good teacherrelationships and adult health remained significant.The results suggest teacher relationships are more important than previously realized and that schools should invest in training teachers on how to build warm and supportive relationships with their students. "This is not something that most teachers receive much training in," Kim said, “but it should be.”8. What does the underlined word “implications" in Paragraph 2 refer to?A. Recipes.B. Habits.C. Benefits.D. Risks.9. What is Paragraph 3 mainly about?A. Poor health in adolescence.B. Limitations of the previous research.C. Teens' relationships with their peers.D. Factors affecting health in adulthood.10. What does Kim's research show?A. Good adult health depends on teens' good teachers.B. Good family background promises long-term adult health.C. Healthy peer relationships leads to students' academic success.D. Positive student-teacher relationship helps students' adult health.11. Where does this text probably come from?A. A health magazine.B. A medical report.C. A term paper.D. A family survey.DMost children who have suffered from ADHD still have it as teens. During teen years, especially as the hormonal changes of teenagers are going on and the demands of school and extra-curricular activities are increasing, ADHD may get worse.Because of problems with getting unfocused and poor concentration, many teens with ADHD have problems in school. Grades may fall, especially if the teen is not getting ADHD treatment. It’s not uncommon for teens with ADHD to forget their homework, lose textbooks, and become bored with their daily class work. Teens may become inattentive or extremely attentive, not waiting for their turn before blurting out answers. They may cut in on their teacher and classmates. Teens with ADHD may also befidgetyand find it hard to sit still in class.Often, teens with ADHD are so busy focusing on other things that they forget about the task at hand. This can be seen especially with homework and athletic skills and in relationships with their schoolmates. This lack ofattention to what they’re doing often leads to bad grades on tests and being passed over for sports teams, after-school activities, and learning teams. Kids with ADHD can be targets for bullying, too. But, not all children with ADHD have trouble getting along with others. If your child does, you can take measures to help improve their social skills and relationships.ADHD affects all parts of a teenager’s life. As a parent you should discover your teen’s troubles as early as possible. The earlier your child’s troubles are discovered, the more successful the following steps can be.12. What does the author plan to do in paragraph 1?A. To list the types of ADHD.B. To introduce the main topic.C. To show the author’s opinion.D. To explain the causes of ADHD.13. What does the underlined word “fidgety” probably mean in paragraph 2?A. Clever.B. Noisy.C. Restless.D. Lazy.14. What is the text mainly about?A. Ways to deal with ADHD.B. Effects of ADHD on teens.C. Teens’ school performances.D. Demands of school work.15. What may the following paragraph talk about?A. How parents can help a teen with ADHD.B. The importance of healthy peer relationships.C. How many children are suffering from ADHD. D. Different opinions about treating ADHD in teens.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。

2019-2020学年大连市第四十八中学高三英语二模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AWhat to See InHarbinParks inHarbin: Snow Sculpture Expo on theSunIslandPark: massive and beautifully carved sculptures of snow. Ice Lantern Festival: where large ice buildings and statues constructed with lights inside that make them glow.SiberianTigerPark: The park has several large caged areas where the tigers roam freely and live as they-would in their natural environment. We enter these caged areas in a specially designed van with large windows to get a look at these beautiful beasts. Live pheasants (雉) are let loose (if you pay) in order to show you the tigers' natural hunting skills.Russian Architecture: Blessed with grace and character, the city is famous for its unique, Russian-influenced architecture. Remnants (残存) from the days when Harbin wasan important stop on the Russian Manchurian Railroad, the dome-shaped structures remind people of pre-revolutionary Russia. The strong Russian flavor continues to impact the city today due to new trade and tourism betweenHarbinandRussia.TheCentral Avenue: Passers-by only street, a perfect remaining part of the busy international business activities at the turn of the 20th century. The 1.4-km long street is a worthy museum of European architectural styles, including Baroque and Byzantine facades, Jewish architectural wonders, little Russian bakeries, French fashion houses, American snack food outlets, and Japanese restaurants.Guogeli Avenue:Harbin's second biggest shopping district dotted with Russian buildings. A tram track is still preserved in the centre of the road. The street is named after Nikolay (Vasilyevich) Gogol (1809-1852); great Russian novelist, dramatist, satirist, founder of the so-called critical realism in Russian literature, best-known for his novel MERTVYE DUSHI I-II (1842, Dead Souls).Saint Sophia Church (built in 1903): The Orthodox church is a wonderful example of Russian Architecture. We only tour the outside of the church. The inside has been turned into some painters' market and is a big disappointment to all who visit it. You are welcome to venture into the church. Entrance fees are RMB20 per person.1. From where does the author look at the tigers?A. Through the windows of his house.B. In the closed areas of tigers.C. In the areas for walking.D. In their natural environment.2. Where can visitors see the most diverse styles of architecture?A. At Ice Lantern Festival.B. On the Russian Manchurian Railroad.C. On TheCentral Avenue.D. OnGuogeli Avenue.3. When walking in the city ofHarbin, what can visitors still strongly feel?A. The Russian flavor.B. The influence of Guogeli's realism.C. The damage to Saint Sophia Church.D. The mixture of American and Japanese cultures.BAt the World Economic Forum last month, President Trump drew claps when he announced the United States would respond to the forum's proposal to plant one trillion(万亿) trees to fight climate change. The trillion-tree idea won wide attention last summer after a study published in the journal Science concluded thatplanting so many trees was “the most effective climate change solution to date”.If only it were true. But it isn't. Planting trees would slow down the planet's warming, but the only thing that will save us and future generations from paying a huge price in dollars, lives and damage to nature is rapid and considerable reductions in carbon release from fossil fuels, to net zero by 2050.Focusing on trees as the big solution to climate change is a dangerous diversion(偏离). Worse still, it takes attention away from those responsible for the carbon release that are pushing us toward disaster. For example, in the Netherlands, you can pay Shell an additional 1 euro cent for each liter of regular gasoline you put in your tank, to plant trees to balance the carbon release from your driving. That's clearly no more than disaster slightly delayed. The only way to stop this planet from overheating is through political, economic, technological and social solutions that end the use of fossil fuels.There is no way that planting trees, even across a global area the size of theUnited States, can absorb the huge amounts of fossil carbon released from industrial societies. Trees do take up carbon from the atmosphere as they grow. But this uptake merely replaces carbon lost when forests were cleared in the first place, usually long ago. Regrowing forests where they once grew can undo some damage done in the past, but even a trillion trees can't store enough carbon to head off dramatic climate changes this century.In a sharp counter argument to last summer's Paper in Science, Justin Gillis wrote in the same journal in October that the study's findings were inconsistent with the dynamics of the global carbon cycle. He warned that “the claimthat global tree restoration(复原) is our most effective climate solution is simply scientifically incorrect and dangerously misleading”.4. What do we know about the trillion-tree idea?A. It was published in a journal.B. It was proposed last summer.C. It was put forward by Trump.D. It drew lots of public attention.5. What is paragraph 3 mainly about?A. A drawback of the tree planting strategy.B. An example of balancing carbon release.C. An anecdote of making a purchase at Shell.D. A responsibility for politicians and economists.6. What was Justin Gillis's attitude towards global tree restoration?A. Indifferent.B. Opposed.C. Hesitant.D. Supportive.7. What is the best title for the text?A. Contradictory Ideas on Tree Planting.B. A Trillion Trees Come to the Rescue.C. Planting Trees Won't Save the World.D. The Best Solution to Climate Change.CThe annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initially consist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinking water for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years. If successful, it will provide a blueprint for other countries facing a similar situation.8. Why doesMaldivesdecide to build MFC?A. It is the lowest-lying country.B. It will be flooded soon.C. It is running out of fresh water.D. It will be unsuitable for living.9. What is Paragraph 2 mainly about?A. The prospect of MFC.B. The developers of the plan.C. The location of the residences.D. The barriers to the construction.10. What can we infer from the underlined words?A. MFC will keep waves away.B. MFC will make use of waves.C. MFC will adjust to the waves.D. MFC will work as water breakers.11. What's the writing purpose of this passage?A. To introduce a construction program.B. To appeal to people to protect nature.C. To seek international help forMaldives.D. To report the achievement of a city plan,DI was at my parent’s dinner table. Before me was a worn journal of thin and discolor1 ed pages. It was my grandfather’s journal and now belonged to my father. My grandfather had passed away in the months leading up to my birth. I never got to visit the places he had frequented and the people who had been a part of his life’sjourney.I was now about to enter his world, through the words he had left behind. Within minutes, I wascaptivatedby the power of the written words. In the magical script (笔迹) before me, I was transported to another age when food was an everyday art, planned, prepared and enjoyed in the company of others, and a time when people had the heart to pause their own lives to embrace (拥抱) each other’s struggles. All this was conveyed to me in the beauty of the words that flowed together to connect with the writer’s mind and understand the world they lived in.That kind of writing seems to be lost on us today. We have gotten used to writing in bite-sized pieces for a public looking for entertainment, and hungry for information. No wonder, there are nearly 200 million bloggers on the Internet and a new blog is created somewhere in the world every half a second. Instead of adding to our collective wisdom, most of these writings reflectthe superficiality (肤浅) and impatience of our day and age.This not only robs us of the skill of writing impressive essays, it also prevents us from exploring what is indeed important. Writing humbles (使谦卑) us in a way that is vital for our character growth, by reminding us about the limits of the self and our appropriate place in the vast flow of life. Writing frees us by helping us explore the unknown so that we really open up to magic of the world around us. I saw all of this in the writing of my grandfather. And I’ve seen it again and again in the writings of the greatest thinkers of humanity. Their writing reflect deep thought on issues of human importance.12. The underlined word “captivated” in the second paragraph can be replaced by “________”.A. puzzledB. frightenedC. attractedD. defeated13. In the author’s grandfather’s age, people ________.A. lived a hard lifeB. cared about each otherC. were fond of writingD. treated food as an art14. The author begins the text with her grandfather’s journal in order to ________.A. show her respect to her grandfatherB. present the importance of good writingC. express her interest in reading as well as writingD. raise the problems with today’s writing15. In the last paragraph, the author is trying to _________.A. discuss what good writing is likeB. express her strong desire to learn writing skillsC. stress the effects of her grandfather’s journal on herD. show her admiration for her grandfather’s 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。

His life was art and his family,” said Jennifer C. Jackson, who was Mr. Ferguson's friend for nearly three decades.” He was a lovable man who was always willing to talk about any topic he was interested in. At shows, people would go crazy for his work,” Ms. Jackson said. “He was also an enthusiastic sailor who loved nothing more than being on the water.” “His sculptures were just memorable,” said Mr. Lund, a Washingtonian. “I used to say, ‘Ferguson, I don't think you know how to do anything that is less than monumental.’”Mr. Ferguson earned a bachelor's degree in 1961 at Holy Cross University, where he developed an interest in painting. He served in the Army for two years until being discharged in 1963, and after studying briefly at the Boston Museum School, registered at the Chicago Art Institute, where he studied until 1966, when he entered the University of Illinois Chicago, where he obtained a bachelor's degree in 1966 in fine arts. Mr. Ferguson developed his interest and skills as a sculptor after moving to Baltimore to do further studies at the Maryland Institute College of Art's Rinehart School of Sculpture, from which he graduated in 1971 with a master's degree in fine arts.“Over the years my work has moved gradually in the direction of elegance and simplicity,” Mr. Ferguson wrotein his artist statement. “Heavy, bulbous forms have been replaced by dancing, winglike forms. The welding process and respect for the qualities of the materials are interrelated and affect the final piece. “Most of the sculptures that are pictured in my works are made from steel, silicon bronze, and to Cor-Ten steel; shaped to create these beautiful and unique pieces of art. As you can see, my sculptures range in size anywhere from 12 inches to 30 feet or larger.”Through the years, his work found its way into such major public and private collections. “They encourage optimism, for they show strength and affirmation; there's nothing negative, depressing or anxiety-ridden about them”, wrote the late art critic John Dorsey in a 1997 exhibition review.4. What did Mr. Lund think of Ferguson?A. Likeable.B. Ordinary.C. Unwelcome.D. Interesting.5. What did Mr. Ferguson do first after serving in the army?A. He studied at the Boston Museum School.B.

Which of the following is a suitable title for the text?A. A stylish, stubborn old manB. Sculptures towering into the cloudsC. JohnD. Ferguson—a famous sculpturer D. The evolution of the sculptural styleCIf you struggle to fall asleep quickly, you’re not alone! Fortunately, thereare plenty of solutions you can try. With a few changes, you can fall asleep fast every night!Keep your room dark. Turn off all the lights above your head when you go to bed. Any bright light can make you believe it is too early in the day for sleep. If you want to read or write before bed, try using a small book light. Now that blue lights can keep you awake, red ones are a great choice.If you can, keep noise in and around your room the lowest at night. If you have an old clock that ticks loudly and keeps you awake, replace it with a silent one. If you share your home with anyone else, request that they keep noises like talking, music, or TV shows at the lowest while you are trying to sleep. It is difficult to fall asleep if you live near a busy road or hear other boring sounds after bedtime. You could get a white noise machine or play recordings of nature sounds, like waves or whales’ singing. You could also listen to soft, relaxing music.Read a book in bed if you have difficulty in falling asleep. Staying in bed doing nothing when you’re having trouble falling asleep may keep you wide awake. While reading in bed may be slightly harmful to your eyes, it can distract (分散) you from your thoughts and help you feel sleepy. But remember to read from a print book rather than something with a screen. The light from electronic screens can keep you awake.Lowering your body temperature helps you sleep, so set the room temperature between 15.5℃-21℃could do the trick.8. What color1 book light should you choose toread before bed?A. Red.B. Blue.C. White.D. Orange.9. What is the author’s attitude towards reading in bed?A. Doubtful.B. Worried.C. Favorable.D. Uncaring.10. What can we inferred from the text?A. Reading on cellphones sometimes helps you fall asleep.B. The lower your temperature while sleeping is, the better.C. Bright lights are better for your reading before going to bed.D. Playing recordings like birds’ singing can improve your sleep.11. How does the author organize the text?A. By givingexamples.B. By asking questions.C. By offering suggestions.D. By listing research results.DLosing your ability to think and remember is pretty frightening. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips you probably needn’t worry. There are pretty clear differences between signs of dementia and age-related memory loss.After age 50, it’s quite common to have trouble remembering the namesof people, places and things quickly,says Dr. Kirk Daffner of Brigham and Women’s Hospital inBoston.The brain ages just like the rest of the body. Certain parts become smaller, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says.When you forget entire experiences, he says, that’s “a red flag that something more serious may be involved”. Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrongBut even then, Daffner says, people shouldn’t panic. There are many things that can cause confusion andmemory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications (药物) like antidepressants.You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive(认知的) reserve, Daffner says.“Read books, go to movies, take on new hobbies or activities that force one to think in novel ways, ” he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a known brain booster12. Why does the author say that one needn’t be concerned about memory slips?A. Not all of them are related to one’s age.B. Not all of them are symptoms of dementia.C. They occur only among certain groups of people.D. They are quite common among fifty-year-old people.13. Which memory-related symptom should people take seriouslyA. Totally forgetting how to do one’s daily routines.B. Inability to recall details of one’s life experiencesC. Failure to remember the names of movies or actorsD. Occasionally confusing the addresses of one’s friends.14. What should people do when signs of serious memory loss show up?A. Check the brain’s cognitive reserve.B. Stop medications affecting memory.C. Turn to a professional for assistance.D. Exercise to improve their well-being15. What is Dr. Daffner’s advice forfight against memory loss?A. Having regular physical and mental checkups.B. Taking medicine that helps boost one’s brain.C. Engaging in known memory repair activities.D. Staying active both physically and mentally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。

A total of 34,503 men were diagnosed（诊断）with a mental disorder.The study found thata mental disorder in young adulthond was linked to a higher risk of having heart attack by middle age. Compared to men without a mental illness in young adulthood，the risk of heart attack was 20%higher among men with a diagnosis.“We already knew that menwho were physically fit in adolescence seem less likely to keep fitness in later years if they have low stress resilience” said study author Dr. Bergh, “Our research has also shown that low stress resilience is also connected with a greater tendency towards bad behavior, such as higher risks of smoking, drinking and other drug use.”“Better fitness in adolescence is likely to help protect against later heart disease, particularly if people stay fit as they age. Physical activities may also reduce some of the bad effects of stress. Those in poor health could benefit from additional support to encourage exercise and develop plans to deal with stress,” said Bergh.8. How does the author develop paragraph 3?A. By giving examples.B. By listing figures.C. By making a comparison.D. By drawing a conclusion.9. What are men with low stress resilience likely to do?A. Smoke more.B. Eat more.C. Sleep less.D. Do less exercise.10. What will Bergh agree with according to the last paragraph?A. Physical activitiesadd to stress.B. Stress may cause heart disease.C. Taking exercise is unnecessary.D. Staying fit is of great importance.11. In which section of a newspaper may this text appear?A. Entertainment.B. Health.C. Education.D. Fashion.DWhere doyou usually put your toothbrush?Do you keep it in the bathroom? How’s your toothbrush looking these days? Even if you can’t see it with a naked eye, experts say it may be saturated(使饱和)with millions of toilet germs!Dr. Charles Oerba, a germ expert, is amicrobiology professor at the University of Arizona. He says there are approximately 3 million bacteria per square inch in most toilet bowls, and every time you flush it without closing the lid, those millions of bacteria droplets spray into the air as far as twenty feet away and dirty everything in their path. And a common victim is your poor toothbrush, usually, left out on the bathroom sink, right?So, what do we do? Dr. Gerba says it’s easy. Close the toilet lid before you flush—that’ll greatly cut downthe germs, which will otherwise float in the air. And wash your toothbrush every few days in mouthwash or peroxide to get rid of any germs hiding in it. You can even put it through the dishwasher to sanitize(消毒)it. And always store your toothbrush in a closed cabinet.Here’s one more tip from Dr. Gerba, who says our kitchen sink is probably dirtier than our toilet. “If an alien came from space and studied the bacterial counts, he probably would conclude he should wash his hands in your toilet and go to the bathroom in your sink.” He says that’s because the kitchen sink is a great place where E. coli(大肠杆菌)to live and grow since it’s wet and damp. Bacteria feed on the food that people put down the drain or—that’s left on dishes in the sink. To reset your sink’s bacteria count back to zero, you’d better regularly wash it with hot water and sanitize yoursink with special chemicals. In fact, you may want to do it every day or before preparing dinner.12. What is the purpose of the text?A. To show how to brush your teeth.B. To tell people the importance of health.C. To warn people of the invisible germs.D. To introduce a microbiology professor.13. What can we learn from Paragraph 2?A. Bathroom sinks are the dirtiest places.B. Bacteria are bad for people’s health.C. Why bacteria spread through the air.D. How bacteria spread in the bathroom.14. What does the underlined word“that”in Paragraph 4 refer to?A. The food.B. The toothbrush.C. The sink.D. The chemical.15. Why does Dr. Gerba mention the example of an alien?A. To tell us a fiction story of an alien studying bacteria.B. To show our kitchen sink may be dirtier than our toilet.C. To teach us how to reset sink’s bacteria count back to zero.D. To prove coli prefers to live in the kitchen and the drain.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。

2019-2020学年大连市第十五中学高三英语二模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ABored with your life? Dreaming of something different? I always wonder what life would be like400 kmabove my head. That's where the International Space Station orbits the earth, with six astronauts living and working on board, for months at a time.How do they sleep? They spend the night floating in a sleeping bag inside a small cubicle (小隔间) on the ceiling. American astronaut Sunita Williams explains, “It's like a little phone booth, but it's pretty comfortable and it doesn't matter if I turn overand sleep upside down. I don't have any sensation (感觉) in my head that tells me I'm upside down.”Brushing your teeth in a place where you can't have a tap or a sink can be a challenge. Can you imagine the mess that running water would make in zero gravity? Canadian astronaut Chris Hadfield uses a straw to put a big blob of water from a sealed bag onto an ordinary toothbrush and adds a little toothpaste which he has to swallow when he's done.Daily exercise is essential. The lack of gravity makes bones more fragile and muscles lose strength — so astronauts are encouraged to work out for at least two hours a day.The role of astronauts in the International Space Station is to act as lab technicians for scientists back on earth. So they spend their time maintaining their environment and performing and monitoring experiments in a confined space about the size of a Boeing 747. Almost every task is carefully planned by mission control — although most astronauts spend their first days losing things until they get used to sticking everything they use to the walls with Velcro, duct tape (强力胶带) or clips (夹子)．One of their most valued perks (额外待遇) is the view from “the office”, dominated by that gigantic blue ball down there, sitting in the darkness of space. Wow! Absolutely breathtaking!1. When they sleep upside down, the astronauts willnot get dizzy because ________.A. they don't feel itB. they sleep in the daytimeC. they sleep in special sleeping bagsD. they are trained to adapt to the conditions of weightlessness2. What parts become weak if astronauts don't exercise?A. Their teeth and bones.B. Their brains and bones.C. Their bones and muscles.D. Their teeth and muscles.3. What is the passage mainly about?A. The Problems We Met in Space.B. Living and Working in Space.C. How to Become an Astronaut.D. The International Space Station.BOne billion people in the world are short of water. How can this problem be solved. Some suggestions have been to desalinate ocean water or to build enormous water pipelines from areas where water is abundant. (Suggestions such as these prove extremely expensive when they are actually used.) One possibility that scientists are considering is pulling icebergs from either the North Pole or the South Pole to parts of the world with a water shortage. Although many questions must be answered before such a project could be tried, moving icebergs seems a reasonable possibility in the future.Engineers, mathematicians, and glaciologists from a dozen countries have been considering the iceberg as a future source of water. Saudi Arabia is particularly interested in this project because it has a great water shortage. Scientists estimate that it would take 128 days to transport a large iceberg (about 1/2 square mile) to Saudi Arabia. Yet the iceberg would be completely melted by the 104th day. Therefore, insulation would be essential, but how to insulate the iceberg remains an unsolved problem.The problems in transporting an iceberg are numerous. The first problem is choosing the iceberg to pull. The icebergs that form in the North Pole are quite difficult to handle because of their shape. Only a small portion extends above the water — most of the iceberg is below the surface, which would make it difficult to pull. South Pole icebergs, on the other hand, are flat and float like table tops. Thus they would be much easier to move.How can a 200-million-ton iceberg be moved. No ship is strong enough to pull such enormous weight through the water. Perhaps several ships could be used. Attaching ropes to an iceberg this size is also an enormous problem. Engineers think that large nails or long metal rods could be driven into the ice. What would happen if the iceberg splits into several pieces during the pulling. Even if an iceberg with very few cracks were chosen, howcould it be pulled through stormy waters. Furthermore, once the iceberg reached its destination, very few ports would be deep enough to store it.All of these problems must be solved before icebergs can become a reasonable source of water. Yet scientists estimate that it will be possible to transport them in the near future. Each year, enough icebergs form to supply the whole world with fresh water for a full year. In addition, icebergs are free and nonpolluting. As a solution to the world’s water problems, icebergs may be a workable possibility.4. What is a problem in transporting iceberg?A. The size of the iceberg.B. The colour of the iceberg.C. The salt in the iceberg.D. The movement of air and water.5. What is the author’ attitude towards transporting iceberg?A. Pessimistic.B. Objective.C. Optimistic.D. Unconcerned.6. What does the last paragraph mainly tell us?A. It is hard to use iceberg.B. Iceberg are a good choice.C. There are problems with iceberg.D. Man finds no other ways to solve water shortage.7. What can be a suitable title for the text?A. Shortage of water.B. Icebergs for water.C. Scientists and icebergs.D. Iceberg—scientists headache.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 afew 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.DScientists often compare coral reefs(珊瑚礁) to underwater rainforests, yet unlike the leafy plant base of a forest, corals are animals. The soft creatures are naturally half-transparent and get their brilliant color1 from algae(藻类) living inside them. When corals experience stress from hot temperatures or pollution, theyhaltthe interdependent relationship with algae, typically pushing them out and turning white. Corals are still alive when they are white, but they're at risk and many eventually die, turning dark brown.Scientists around the world are looking for means to protect and maybe increase corals. One common option is to create more protected areas — essentially national parks in the ocean. Beyond nature preserves, some conservationists are looking to more hands-on methods. One research center in the Florida Keys is exploring a form of natural selection to keep corals remaining. The reef system in the Keys has been hit hard by climate change and pollution, which is especially tough, because corals there help support fisheries worth $ 100 million every year.To keep the wild ecosystem alive, Erinn Muller, the center's director, and her team are harvesting samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea. So far, the center has regrown over 70,000 corals from five different species on damaged reefs.In The Bahamas, Ross Cunning, a research biologist at Chicago's Shedd Aquarium, focuses on corals with genes that could make them natural candidates for restoration projects. He published a study of two Bahamian reefs, one that survived an extreme 2015 heat wave, and one that didn't. "We think their ability to deal with these higher temperatures is built into their genes," says Cunning. There's evidence of corals evolving more quickly to resist rapidly warming climate. The big question scientists need investigate, adds Gunning, is how much more heat corals can adapt to.12. What does the underlined word "halt" in the first paragraph mean?A. End.B. Develop.C. Strengthen.D. Weaken.13. What do Muller and her team do to save corals?A. Restore the damaged reefs.B. Grow corals by hand underwater.C. Create more protected areas.D. Move corals to unpolluted areas.14. What do Gunning's words suggest?A. Many corals have been genetically improved.B. Cooling down the waters is key to rescuing corals.C. Reasons for corals surviving heat waves are shocking.D. The highest temperature corals cansurvive is unclear.15. Which can be a suitable title for the text?A. Relationship between corals and algaeB. Efforts made to save coralsC. Impact of climate warming on coralsD. Survival crisis faced by coral reefs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。
2019-2020学年大连市中山区实验学校高三英语二模试卷及答案
2019-2020学年大连市中山区实验学校高三英语二模试卷及答案第一部分阅读（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AOne day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem inability to read.In the library,I found my way into the "Children's Room." I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle. Without opening the book—Amos, the Beagle with a Plan ,1 borrowed it from the library for the summer.Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book.I never told my mother about my “miraculous” experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later ,she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.1. The author's mother told him to borrow a book in order to ________.A. let him spend a meaningful summerB. encourage him to do more walkingC. help cure him of his reading problemD. make him learn more about weapons2. The book caught the author's eye because .A. it reminded him of his own dogB. he found its title easy to understandC. it contained pretty pictures of animalsD. he liked children's stories very much3. Which one could be the best title of the passage?A. Mum's Strict Order.B. My Passion forReading.C. Reunion with My Beagle.D. The Charm of a Book.BThis past year, I've found myself returning again and again to lines of poetry by Emily Dickinson. Like many people, I've needed the curing effects of reading more than ever. As scientists and psychologists will tell you, books are good for the brain and their benefits are particularly vital now.Books expand our world, providing an escape and offering novelty, surprise and excitement. They broaden our view and help us connect with others. Books can also distract us and help reduce ourmental chatter.When we hit the “flow state" of reading where we're fully lost in a book, our brain's mode network calms down. It's a network of brain that is active and gets absorbed in thinking and worrying endlessly when we are not doing anything else.There is so much noise in the world right now and the very act of reading is kind of meditation. You disconnect from the chaos around you.You reconnect with yourself when you are reading. And there's no more noise.In 2020, the NPD Group recorded the best year of book sales since 2004. Yet even as people are buying more books,many are reporting they're having a harder time getting through them. It's difficult for your brain to focus on a book when it's constantly scanning for threats to keep you alive.Our fight-or-flight response has been consistently activated.Sometimes I picture my brain as a cartoon brain with little arms and legs, fighting with a book I am holding and screaming: “Can't you see I'm busy!” Anxiety causes our brain to produce a flood of stress,which consumes our energy and makes it harder to concentrate.Then one day in December sitting on my couch, I remembered how much I like to read"The House of Mirth" every few years around the holidays. The memory inspired me to pick up the familiar book, opened it up and started reading.I just kept going.The comfort and distraction and brain-opening experience gave me peace.So return to something familiar.4. What does the underlined part “mental chatter” in Paragraph 2 mean?A. Getting lost in a book.B. Non-stop inner anxiety.C. Chatting with the author.D. Powerful network of brain.5. What do we know about reading according to the text?A. It can treat our headache.B. It can calm down the noisy people.C. It forces us to concentrate.on thinking.D. It makes us communicate with ourselves.6. Why was it difficult for people to finish reading books in 2020?A. People bought too many books.B. The books were too difficult to understand.C. People just wanted to escape from the threat.D. The life threat disturbed people's focus on books.7. Why is the author's experience mentioned in the last paragraph?A. To rid people of concern for safety.B. To present an effective reading way.C. To wake up memories of an old book.D. To recommend the book he/she reads.CLast summer, Maria and her mother moved from their house in the countryside to a flat building in Chicago. Maria really liked some things about the city, but she missed her house and yard in the countryside.One day, Maria was in her flat building when she noticed her neighbor, Mrs. Garcia, carrying a gardening tool and a bag of soil. Maria wondered how Mrs. Garcia was able to garden in the city.“My mom used to grow the most delicious vegetables, and I know she misses her garden now that we don’t have a yard,” said Maria.Mrs. Garcia laughed. “I’ll show you,” she said.Maria thought that Mrs. Garcia would take her to the park, but she took her to the roof. When the door opened, Maria was surprised to see rows of flowers and vegetables on the roof.“What a wonderful garden!” said Maria.Mrs. Garcia told Maria that for a long time the roof was just an empty space. Then some of the people in the building asked the owners to turn it into a community garden. The building owners liked the idea because the plants not only helped to keep the air clean, but they also helped to keep the building cooler during warmer weather.“I plant flowers in my own place,” Mrs. Garcia said, “but you would be surprised by how different the plants are up here. Some people grow vegetables just like your mom. You can do some of the same things in the city as in the countryside. You just have to be creative!”8. Where did Mrs. Garcia take Maria to one day?A. The park.B. The roof.C. The garden in front of her house.D. The countryside.9. Which of the following is NOT the good side of the community garden?A. It made the building stronger.B. It helped keep the air clean.C. It helped keep the building cooler.D. It used the empty space well.10. After Maria visited the garden, she would most probably ask her mom to ________.A. go back to the countrysideB. pick flowers from the gardenC show her around the park D. grow vegetables on the roof11. What is the best title for this passage?A. A Creative LadyB. An Empty RoofC. A Rooftop GardenD. A Special BuildingDAfter finishing his dinner, Lin Xu opened a WeChat mini-program called "Clear Plate" on his phone and took picture of the empty plates. He was then awarded 157 credit points after the image was uploaded and recognized by artificial intelligence.“Users of the app can use their credit to buy gifts, such as books and cellphones to purchase charity meals donated to children in poor rural areas,” Lin said.A nationwide "Clear Your Plate" campaign is gaining steam online. Efforts to stop food waste and promote thrift are also being made by restaurants that have been urged to create an environment in which consumers are reminded not to waste food. They are also encouraged to offer different portion sizes so that customers can have more choices.The “Clear Plate” mini-program has become popular among young Chinese and currently has nearly 1 million users.Liu Jichen, founder of the startup that developed the app, said that the idea popped up at a dinner in 2017, when Liu found that a restaurant would give diners who polished off their food a card and offer small gifts after a certain number of cards had been collected.“Such an idea can be realized online,” Liu said. He formed a team to work on the project.Yet it was quite challenge for the AI system to identify whether the uploaded photos showed empty plates.To make the AI system smarter, Liu and his team, assisted by more than 1,000 others, spent half a year collecting over 100, 000 samples in canteens and restaurants across the country and used the data to train neural network. Dozens of enterprises, institutions and restaurants have contacted the startup to cooperate on the project.Through the visualized mini-program, people can clearly see the good results of saving food, which will effectively reduce waste, he noted. "We hope our efforts can start a new trend among the younger generation, encouraging them to carry out the virtue of cherishing food and developing the habit of thrift, " Liu said12. What is the main function of the APP "Clear Plate?A. Awarding credit points.B. Giving charity meals.C. Showing the empty plates.D. Encouraging saving food.13. How is the "Clear Your Plate" campaign carried out?A. Customers wasting food are punished.B. People join in it on mini-program.C. Restaurants limit customers' choices.D. People are encouraged to buy gifts.14. What was the most difficult when the app was created?A. Getting other people to cooperate with the team.B. Collecting samples in canteens and restaurants.C. Ensuring the app to recognize empty plates.D. Finding people to fund the app.15. What is the purpose of the writing?A. To introduce an app.B. To promote saving food.C. To praise a startup founder.D. To raise fund for poor children.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。

2019-2020学年大连市第四十四中学高三英语二模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AIt looks like 2017 is shaping up to be a record-breaking year in movie History. Here is a list of some of the year’s biggest blockbusters so far.Kong: Skull IslandA reboot (重启) of King Kong would normally get laughed at in this day and age, but it looks like this modem version of the story will be worth watching. With US actress Brie Larson and UK actor Tom Hiddleston in the mix, this film is set to be this year’s biggest monster tale.Release Date:3/10/17Beauty and the BeastDirector Bill Condon is bringing back a part of our childhood in live action, complete with the songs we all remember and love. With British stars Emma Watson and Dan Stevens leading thecast, the classic Walt Disney story already sounds like it’ll be a delight for both children and adults.Release Date:3/17/17The Fate of the FuriousThere was doubt that we’d even get a Fast 8, especially after the fitting ending US actor Paul Walker’s character was given at the end of Furious 7. Fans thought they’d never see Dom and the rest of the crew back in action, but thankfully, US star Vin Diesel himself confirmed that The Fate of the Furious is fueling up for another go.Release Date:4/14/17Spider-Man: HomecomingSpider Man is heading home to Marvel Studios for the first time. The movie will show us Peter Parker’s high school days, and will continue the threads we saw formed during his initial appearance in Captain America: Civil War. We know that Michael Keaton is playing The Vulture in this story, and that both Happy Hogan and Tony Stark, played by US actors Jon Favreau and Robert Downey Jr., are along for the ride.Release Date:7/7/171.Which of the following movies can’t you see on May Day?A.Kong: Skull Island.B.Beauty and the Beast.C.The Fate of the Furious.D.Spider-Man: Homecoming.2.What can we know about Beauty and the Beast?A.It is fueling up for another go.B.It is produced by Marvel StudiosC.It’ll show us Peter Parker’s school days.D.It’ll be enjoyable for both children and adults.3.What does the underlined word “cast” probably mean?A.Characters.B.Actors.C.Directors.D.Teachers.BIn the summer of 2016, I gave a talk at a small conference in northernVirginia. I began by admitting that I’d never had a social-media account; I then outlined arguments for why other peopleshould consider removing social media from their lives. The event organizers uploaded the video of my talk to YouTube. Then it was shared repeatedly on Facebook and Instagram and, eventually, viewed more than five million times. I was both pleased and annoyed by the fact that my anti-social-media talk had found such a large audience on social media.I think of this event as typical of the love-hate relationships many of us have with Facebook, Instagram, and other social-media platforms. On the one hand, we’ve grown cautious about the so-called attention economy, which, in the name of corporate(公司的) profits, destroys social life gradually and offends privacy. But we also benefit from social media and hesitate to break away from it completely. Not long ago, Imet a partner at a large law firm in Washington, D.C., who told me that she keeps Instagram on her phone because she misses her kids when she travels; looking through pictures of them makes her feel better.In recent months, some of the biggest social-media companies, Facebook and Twitter, in particular, have promised various reforms. In March, Mark Zuckerberg announced a plan to move his platform toward private communication protected by end-to-end encryption(端对端加密); later that month, he put forward the establishment of a third-party group to set standards for acceptable content.All of these approaches assume that the reformation of social media will be a complex, lengthy, and gradual process. But not everyone sees it that way. Alongside these official responses, a loose collective of developers that calls itself the IndieWeb has been creating another alternative.

In American football, a tackle (抢断球) refers to an attempt to stop an opponent by forcing them to the ground.The number of participants in football grew in 2015 while most other sport, except baseball, posted a decline, USA Football said on Monday, citing(引用) the findings of a survey of 30,000 children and teenagers.Participation in flag football (a no-tackle type of football) increased by 8.7 percent among children aged 6 to 14, while tackle football rose by 1.9 percent. For that age group, the only other sport that grew was baseball, with a 3. 3 percent increase.In the 15-to-18 age group, flag football rose by 10. 5 percent, while tackle grew by 2.5 percent.Basketball was the third, with a 1. 1 percent increase. Participation in all other sports declined.Tom Farrey, executive director of the Aspen Institute's Sports & Society Program, said he was surprised that flag football participation rose so much.“The trend suggests that parents aremarching to the beat of a different drummer, in pursuing flagas an alternative for their kids," he said.The findings come at a time of increasing concern about the risk associated with youth sports, particularly hockey (曲棍球) and football, where medical researchers have warned about the risk of concussions (damagesto the brain caused by violent blows to the head) and death linked to brain injury.USA Football, anIndianapolis,Indianabased nonprofit funded in part by the National Football League, believed that the increases resulted from better safety and health education."Football participation increases, even modest increases, may signal that programs such as our Heads Up Football program and practice guidelines are making a positive difference," said Scot Hallenbeck, USA Football chief executive, in a statement.Robert Cantu, aBostonUniversityneurosurgery professor and investigator at the school's chronic Traumatic Encephalopathy (CTE) Center said the increase in fag football participation signaled that more parents were directing children to a safe alternative8. What can we learn about the two age groups?A. Flag football grew the fastest in the 6-to-18 group.B. Tackle football grew he fastest in the 6-to-14 group.C. Participation in baseball declined the most in both groupsD. Participation in tackle football increased the most in both groups.9. The underlined part probably means ________.A working at a different paceB. behaving in a different wayC. ignoring the major differencesD. trying to accept different opinions10. The popularity of flag football is inked with the fact thatA. its rules have been adapted for young playersB. it receives more funds than other varietiesC. tackle football is an old-fashioned gameD. experts worry about children's safety11. What is the cause of football growth according to USA Football?A. Their safety programs are successful.B. More children show interest in the game.C. Football is less likely to cause concussions.D. There are different types of football to choose from.DA company called Neuralink has shared a video where a monkey is playing a video game. That' s fairly unusual, but what makes the video even stranger is that the monkey is playing the video game with just his mind.The monkey in the video is called Pager who has two of Neuralink's special "Link" devices(装置)inside his brain. The devices planted in Pager's brain are connected to 2,048 wires which lead to the parts of Pager's brain that control movements of the arms and hands.Scientists taught Pager to play a video game. At first, Pager controlled the video game using a joystick it, which is a normal gaming controller. But as Pager played, his Link devices wirelessly sent out information about the signals his brain was using to control his arms and hands. Neuralink's scientists recorded all of these signals.Then they used computers to match the signals from Pager's brain to the movements that his hands were actually doing. This was the most difficult work and the scientists counted on artificial intelligence ( AI) to help them decode(解码)Pager's brain signals.The final step was to have a computer make moves inthe video game as if Pager had actually moved the joystick. If Pager thought about moving the joystick up, the computer would send an “up” signal to the video game.At first, the researchers let Pager keep moving the joystick with his hand, even though it was no longer connected to the computer. But soon Pager was able to play the video game using just his brain.Even though Neuralink's work right now focuses on animals and video games, there's a very serious purpose behind it. Neuralink wants to make it possible for humans who have lost the ability to make physical movements to interact with the world around them.12. What are “Link” devices used to do?A. To pick up the arms' and hands' signals.B. To link the computer to the monkey's brain.C. To send out information about the brain's signals.D. To control movements of the arms and hands.13. What challenged scientists most in the study?A. Recording and sending out body signals.B. Training Pager to use the joystick correctly.C. Planting "Link" devices into Pager's brain.D. Matching brain signals to body movements.14. What is Neuralink's real purpose of the study?A. To test artificial intelligence.B. To help those without arms or legs.C. To study how animals play video games.D. To develop more complex video games.15. What can be the best title for the text?A. Video Games for Animals Are Developed.B. Science Proves the Intelligence of Monkeys.C. Monkey Plays Video Games Using His Mind.D. Neuralink Is Leading the World in Technology.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。
2019-2020学年大连市第四十四中学高三英语二模试题及答案
2019-2020学年大连市第四十四中学高三英语二模试题及答案第一部分阅读（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AObesity (肥胖症) is becoming a problem in our busy society, and almost one in three American adults is now considered to be obese. Children obesity is alsoat an all-time high.Obesity means being very overweight. If you are obese, you have too much bodyfat. If you eat more food than your body can use, this will make you put on weight. Food that your body does not need will be stored as fat by your body.The following are the major factors that increase the risk of obesity.What you eat plays a major role in weight gain. Eating a lot of fast food such as hamburgers, sweet drinks, ice creams and other sweet food can increase the risk of becoming obese.If you do not do enough exercise, you will put on weight as the food you eat is not being used to make energy for physical activities.The chances of you being obese are greater if your parents are obese.There are many psychological factors that cause people to eat too much. People who are worried, unhappy or bored will often eat to make themselves feel better. This is known as comfort eating.Age is another factor, as you tend (趋于) to be less active when you get older. When you get older, you need to eat less, and if you do not eat less, you will put on weight. Obesity can cause many health problems such as heart problems, high blood pressure and many other serious medical conditions.1. The underlined sentence in paragraph 1 means that ____.A. obesity does not do harm to health.B. there are more obese children than before.C. all the American children are obese.D. there are less obese children in the USA.2. According to the passage, there are ____ major factors that increase the risk of obesity.A. threeB. fourC. fiveD. six3. What will the writer most probably talk about after the last paragraph?A.

How doctors treat heart problems.BBill Gates on how to fight future pandemicsWHEN HISTORIANS write the book on the covid-19 pandemic, what we've lived through so far will probably take up only the first third or so.The bulk of the story will be what happens next.I believe that humanity will beat this pandemic, but only when most of the population is vaccinated(接种疫苗）.Until then, life will not return to normal.As the pandemic slows in developed nations,itwill accelerate in developing ones.Their experience,however,will be worse.In poorer countries,where fewer jobs can be done remotely,distancing measures won't work as well.The virus will spread quickly,and health systems won't be able to care for the infected.Wealthy nations can help.But people in rich and poor places alike will be safe only once we have an effective medical solution for this virus,which means a vaccine.My hope is that,by the second half of 2021,facilities around the world will be manufacturing a vaccine.If that's the case,it will be a history-making achievement: the fastest humankind has ever gone from recognizing a new disease to immunizing（免疫）against it.Apart from this progress in vaccines,two other big medical breakthroughs will emerge from the pandemic.One will be in the field of diagnostics.The next time a novel virus crops up,people will probably be able to test for it at home.Researchers could have such a test ready within a few months of identifying a new disease.The third breakthrough will be in antiviral drugs.We haven't been as effective at developing drugs to fight viruses as we have those to fight bacteria.But that will Researchers will develop large diverse libraries of antivirals,which they'll be able to scan trough and quickly find effective treatments for novel viruses.All three technologies will prepare us for the next pandemic by allowing us to intervene(干预）early when the number of cases is still very low.Our progress won't be in science alone.It will also be in our ability to make sure everyone benefits from that science.In the years after 2021,I think we'll learn from the years after 1945. With the end of the Second World War, leaders built international institutions like the UN to prevent more conflicts.After covid-19, leaders will prepare institutions to prevent the next pandemic.These will be a mix of national,regional and global organizations.I expect they will participate in regular"germ games”in the same way as armed forces take part in War games.These will keep us ready for the next time a novel virus jumps from bats or birds to humans.I hope wealthy nations include poorer ones in these preparations,especially by devoting more foreign aid to building up their primary health-care systems.This pandemic has shown us that viruses don't obey border laws and that we are all connected biologically by a network of microscopic germs,whether we like it or not.The best analogy(类比）for today might be November 10th 1942.Britainhad just won its first land victory of the war,and Winston Churchill declared in a speech: “This is not the end.It is not even the beginning of the end.But it is,perhaps,the end of the beginning.”4. What are the three technologies that will prepare us for the next pandemic?①manufacturing a vaccine fast②diagnosing a virus at home③developing antiviral drugs④allowing us to intervene earlyA. ①②③B. ①②④C. ①③④D. ②③④5. As far as poorer countries areconcerned,which of the following is TRUE according to this passage?A. pandemic disease is more likely to begin in poorer countriesB. Working from home can work well in poorer countries.C. Health systems are sufficient to care for the infected in poorer countries.D. Virus will cross borders if poorer countries fail to contain it.6. Why is the Second World War mentioned in Para.8?A. The fight against the COVID-19 is similar to the Second World War.B. People are suffering just as they were in the Second World War.C. We should cooperate globally just as we did after the Second World War.D. Countries are fighting each other like in the Second World War.7. What is the tone of this passage?A. pessimisticB. optimisticC. neutralD. indifferentCOn September 7, 1930, Yuan Longping was born inBeijing. Fluent in English, his mother often read Friedrich Nietzsche's works to him. Influenced by his mother, Yuan Longping liked English,geography and chemistry at school. After graduating from university, he became a teacher in the countryside ofHunanin 1953.With lots of crop failures, nationwide hunger hitChinain the 1960s, making many people live a bad life. Yuan was sad and felt he must do something. Since the climate inHunanwas not friendly to growing wheat. He decided to devote himself to studying how to increase the production of rice, a basic food for over 60 percent of Chinese people. From then on, he began a lifelong connection with rice.Yuan Longping succeeded in growing the world's first high production hybrid rice (杂交水稻) variety in 1973, which could reach a yield of over 500 kg per more than 200 kg than before. For the next four decades, he continued to work on the research of hybrid rice. In 2020, hybrid rice developed by his team achieved 1,500 kg permuin two growing seasons, a new world record.Nowadays, the hybrid rice is grown in almost half ofChina's rice fields and its production accounts for 60 percent of the total rice production inChina. The hybrid rice production is 20 percent more than the common kinds , the yearly increase of which feeds up to 100 million people.In 2019, Yuan Longping, known as the “Father of hybrid rice”, was awarded with Medal of the Republic,China's highest honor.Yuan Longping's biggest dream in life was to develop more hybrid rice varieties, which could be grown all over the world to help solve the global food problem. So far, the hybrid varieties he developed have been grown in over 40 countries, including theUSA,BrazilandIndia.8. What do we know about Yuan Longping according to the text?A. He began to study hybrid rice in 1973.B. He received the highest honor inChinaat 90.C. He ever taught math in the city after graduation.D. He ever hoped Chinese would be free from hunger.9.

The education of Yuan Longping.DBabies who frequently communicate with their caregivers using eye contact and vocalisations(发声)at the age of one are more likely to develop greater languages skills by the time they reachtwo,according to new research.In the study, researchers looked at 11-and 12-month-od babies' vocalisations. gestures and gaze behaviours ,and at how their caregivers responded to them.To measure he interactions ,the researchers videoed infants(婴儿)and caregiver at home,and asked them to play as usual.They took those recordings back to the universityThe scientists then used statistical models to find that the best predictor of vocabulary at 24 months was when infants were seen to use vocalsatioms while looking at their caregiver's face when they were about a year old.The benefits were even greater when these interactions were followed by responses from the caregiver.The statistics showed that at 19 months,children had an average of about 100 words.Those who exhibited the beneficial interactive behaviour earlier in life were seen to have an average of about 30 extra words."The message of this paper is thatitis the result of a joint effort; noticing what your child is attending to and talking to them about it will support their language development." said McGillion, a co-author of the work."The joy of this message is that that can happen in any context... across any part of your day.It's not something that requires special equipment or even lots of time.I can happen when you're doing the laundry,for example—when you're taking out the socks, you can talk about socks...in the park, in the car, at mealtimes,at bathtimes.This finding can be used in any context,"added McGillion."This is a developmental snapshot in the first year of life, but children are constantly growing and changing and so are their behaviours. It would be interesting to look at these sorts of behaviours again as children progress through the second year of life to see what's happening there,"said Donnellan,the lead author on the study.12. How did the researchers get the findings?A. By interacting with babies.B. By asking babies to vocalize.C. By analyzing relevant recordings.D. By referring to the previous statistics.13. What does he underlined word "it"in Paragraph 5 mean?A. Infants' eye contact.B. Infants' larger vocabulary.C. The response from caregivers.D. The best predictor of vocabulary.14. What did McGilion say about infants' interactive behaviour?A. I's easy to perform.B. It's complex to understand.C. It's difficult to copy.D. It's interesting to video.15. What might further studies be on?A. Children's academic progress.B. Children's growing environment.C. Children's potential physical development.D. Children's behaviours across more age ranges.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。

DJs are already unhappy because they have to make sure that 40 per cent of the songs they play are in French. Radio bosses say the new rule will make French people switch to music streaming services instead of listening to the radio to listen to American or British songs. France says the new law is to protect its culture from American and British influences. It wants to stop the English language from getting deeper into French culture. The French music industry says the new law is necessary for the French language and French music. French musicians say the law is important to protecting French musicians. One musician said: “It remains important for French artists to have the chance of making a career out of music.”。
