2021年北京工业大学附属中学初中部高三英语下学期期中试卷及参考答案
2021年北京工业大学附属中学初中部高三英语下学期期中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AA medical capsule robot is a small,often pill-sized device that can do planned movement inside the body after being swallowed or surgically inserted. Most models use wireless electronics or magnets or a combination of the two to control the movement of the capsule. Such devices have been equipped with cameras to allow observation and diagnosis, with sensors that “feel,” and even with mechanical needles that administer drugs.But in practice, Biomechatronics engineer Pietro Valdastri has found that developing capsule models from scratch (从头开始) is costly, time-consuming and requires advanced skills. “The problem was we had to do them from scratch every time,” said Valdastri in an interview. “And other research groups were redeveloping those same modules from scratch, which didn’t make sense.”Since most of the capsules have the same parts of components: a microprocessor, communication submodules, an energy source, sensors, and actuators (致动器), Valdastri and his team made the modular platform in which the pieceswork in concertand can be interchanged with ease. They also developed a flexible board on which the component parts are snapped in like Legos. The board can be folded to fit the body of the capsule, down to about 14 mm. Additionally, they compiled (编译) a library of components that designers could choose from, enabling hundreds of different combinations. They arranged it all in a free online system. Designers can take the available designs or adapt them to their specific needs.“Instead of redeveloping all the modules from scratch, people with limited technological experience can use our modules to build their own capsule robots in clinical use and focus on their innovation,” Valdastri said.Now, the team has designed a capsule equipped with a surgical clip to stop internal bleeding. Researchers at Scotland’s Royal Infirmary of Edinburg have also expressed interest in using the system to make a crawling capsule that takes images of the colon(结肠). One research group, led by professors at the Institute of Digestive Disease of the Chinese University of HongKong, is making a swimming capsule equipped with a camera that pushes itself through the stomach.One limitation of Valdastri’s system is that it’s only for designing models. Researchers can confirm their hypotheses (假设) and do first design using the platform, but will need to move to a custom approach to developtheir capsules further and make them practical for clinical use.1. According to the passage, Valdastri and his team created the platform to ________.A. adopt the latest technologiesB. make their robots dream come trueC. help build specialized capsule robotsD. do preciser observation and diagnosis2. What does the underlined phrase “work in concert” mean in Para.3?A. Perform live.B. Run independently.C. Act in a cooperative way.D. Carry on step by step.3. What can be learnt from the passage?A. Valdastri’s system can’t provide a complete capsule creation.B. The modular platform is more useful than a custom approach.C. The capsules can move in human’s body automatically.D. It costs more to module the capsules on the board.BDid you know that the average child has heard the word "no" over 20,000 times before they turn the age of three? Ironically, it is also around this time that children begin to develop enough personal character to refuse to obey. The "terrible twos" are categorized by a lack of understanding. Somewhere between three and four, children begin to acquire the skills to reason. It is during this time they watch how other children and adults reason. If we're not careful, the children will watch us model a world of "NOs".By the time a person turns eighteen, how many times have they been told no? I haven't found any studies that even attempted to track this statistic, but I'm sure if the number is 20,000 by three, then at eighteen that number has multiplied. You can do the math.Anyway, I think I know why we say no. We say no to protect. We say no to direct. We say no to stop potential confusion. However, do we sometimes say no just for the sake of saying no? Do we say no because we have internalized(内在化)all of the "NOs" we've heard over the years and we feel it is finally our time to say no to someone else?The internalized no can damage the growth process of dreams in infancy as quickly as it can weaken a three-year-old. And we wonder why we run intopeople with big, un-accomplished dreams who have a bit of a chip on their shoulder. They have to take on the 20,000 NOs. However, the thing that keeps them going is thepossibility of the power of ONE YES! Just as it only takes one book to make a writer a Pulitzer Prize Winner, it only takes one word to change the course of your day. That word is YES!4. What do we know about two- year- olds?A. They understand well.B. They often say no to others.C. They think logically.D. They don't do all they're told.5. What effect does saying no have on children?A. They lose all their dreams.B. They aren't easy to succeed.C. They don't make mistakes.D. They never say yes to others.6. Which word best describes the author's attitude to a world of "NOs"?A. Tolerant.B. Disapproving.C. Favorable.D. Carefree.7. What is the text?A. A how-to guide.B. A survey report.C. An opinion essay.D. A short story.CDoctors are known to be terrible pilots. They don’t listen because they already know it all, I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn’t realize then, but becoming a pilot makes me a better surgeon. I loved flying. As 1 flew bigger, faster planes, and in worse weather, I learned about crew resource management (机组资源管理), or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.I first read about CRM in 1980. Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot. He was so busy because of the bad turn, he had forgotten to put the landing gear (起落架) down. He was a better pilot—and my boss—so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness sand said, we need to put the landing gear down now! That was my first real lesson in the power of CRM, and I’ve used it in the operating room ever since.CRM requires that the pilot/surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn’t overreact, which might prevent fellow doctors from voicing opinions again. So when I’m in the operating room, I ask for ideas and help from others. Sometimes they’re not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from landing gear up.8. What does the author say about doctors in general?A. They like flying by themselves.B. They are quick learners of CRM.C. They pretend to be good pilots.D. They are unwilling to take advice.9. The author deepened his understanding of the power of CRM when .A. his boss landed the plane too lateB. he was in charge of a flying taskC. he saved the plane by speaking upD. his boss operated on a patient10. In the last paragraph landing gear up probably means .A. following flying requirementsB. making a mistake that may cost livesC. listening to what fellow doctors sayD. overreacting to different opinions11. Which of the following can be the best title for the text?A. CRM: A New Way to Make Flying SafeB. A Pilot-Turned DoctorC. The Making of a Good PilotD. Flying Makes Me a Better DoctorDYour best friend that follows you around when the sun comes out - your shadow - doesn’t serve an important function like your heart or brain, but what if you could use shadows to create electricity? When using solar panels (电池板) that are powered by light, shadows can be boring because it means electricity can’t be created. However, researchers from the National University of Singapore have engineered a way to create power from the shadows present everywhere.A team of the university created a machine that can collect energy from shadows. It is created by placing a thin coating of gold onto silicon (硅). Like in a normal solar panel, when put in light, the silicon electrons (电子) become energized and the energized electrons then jump from the silicon to the gold. The voltage (电压) of the part of the machine that is placed in the light increases to the dark part and the electrons in the machine flow from high to low voltage. They are sent through an external circuit (外电路) creating a current that can be used topower another machine. The greater the contrast between light and dark, more energy is provided by the machine.The team isworking on improving the performance of the machine, borrowing approaches from solar panels to gather light. Increasing the amount of light the machines can receive allows them to better make use of shadows, as well as developing shadow energy collecting panels that can successfully gather from indoor lighting. The team is also researching the use of other materials other than gold to drop the price of the machine, meaning they would be more cost effective and easier to apply in society.Shadows are present everywhere and perhaps one day in the future we will be able to collect energy from them by placing the shadow-effect energy machine around the world in places that have been considered unfit for solar panels to work, or indoors. “A lot of people think that shadows are useless,” Tan says, but “anything can be useful, even shadows.”12. What is Paragraph 1 mainly about?A. Your best friend always stays with you after the sunrise.B. The shadow has the same function as the heart and brain.C. Shadows can stop solar panels from creating electricity.D. Researchers have found a way to create power from shadows.13. What is the key working principle of the machine mentioned in the text?A. The silicon produces electricity when it is in the light.B. The gold produces power with the help of the silicon.C. The energized electrons flow from high to low voltage.D. An external circuit creates current using another machine.14. How does the team improve the performance of the machine?A. Using solar panels in the machine.B. Increasing the amount of light received.C. Developing light energy collecting panels.D. Bringing down the price of gold.15. Which of the following is the best place to apply the machine?A. A gym.B. A park.C. A farm.D. A playground.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。

Marcos,Age 14When his neighbor's home was burning,Marcos climbed into the burning home and saved the life of an 8-year-old girl,who was inside the house.Marcos,like a true hero,said, "I can't say I am a hero.I think anyone would have done what I did."Riley,Age 5Riley was swimming in a pool,when she noticed an 18-month-old toddler（蹒跚学步的孩子）fall in.Riley,a strong swimmer,was going to call for help,but she couldn't see any adults nearby.So,Riley saved the girl from the bottom of the pool herself.When she got out of the water,she yelled,"I've got the baby!I've got the baby!"Jaden,Age 9Jaden was staying at home on a Sunday,when two robbers（劫匪）entered his house.Jaden,beingthe smart kid that he is,hid in a closet.When he heard his parents talking to the robbers in the living room,he made a run for it,out a bedroom window and to a neighbor's house.The neighbor called 911 and when the officers arrived,the two robbers were still in the house.Piper,Age 10Piper,who is blind,was outside playing with her little brother and friend Irie when a raccoon（浣熊）was trying to hurt Irie.Piper asked Irie to describe the animal to her,then used a stick to beat at the raccoon until it let Irie free.There were six bites on Irie's body,but it would have been much worse if Piper hadn't stepped in.31.How old is Marcos______A. 10.B. 9.C. 14.D. 5.32.According to the passage,we know that Riley is ______ .A. a brave boyB. a blind girlC. a fast rummerD. a good swimmer33.Which of the following is TRUE about Jaden？______A.

Irie was Piper's elder sisterB. Piper's little brother hurt herC. Irie knew a lot about animalsD. Piper made the raccoon leaveWMy mother was having a baby,and we were very glad.We did not know when the baby would come,but we knew it was soon.My mother had a suitcase she had packed（收拾）.She kept it next to the door.She had put some things she would need when she went to the hospital in it. Then one night my mother woke us up and said, "It is time!"We were very.excited.She said that my aunt would take care of us while she was at the hospital.I wanted to go,too,but she said I would come later. "Go back to sleep," she said. "I will see you soon with the new baby."The next morning,my aunt said,"Now you have a new brother." I was glad.I wanted to see him,but my aunt said, "You can't come to the hospital.You are too young." Still,I wanted to see the baby,and I missed my mother.My mother called me on the telephone.She stayed in the hospital for a few days,and I hadmissed her even more.When I talked with her on the phone I felt better.She said she was feeling good and would be home soon.She said the nurses had taken good care of her.The next day,I went to the hospital.We were taking my mother home,and my aunt drove us there.When we got there,my mother was in a wheelchair.I thought there was something wrong. "Are you sick？" I asked.The nurse said, "No,she is just being careful.When patients leave the hospital they leave in a wheelchair.That keeps them safe."My mother thanked the nurse.She said she and the baby would be back next week to see the doctor.She would bring us,too.She said this was a very special time for our family.We would all help take care of each other.We would take good care of my brother.We would return to the hospital to check with the doctor to make sure he was healthy.35.The mother might feel ______ before going to hospital.A. sadB. afraidC. excitedD. surprised36.From the passage we know that the writer had a（an）______ .A. little sisterB. little brotherC. elder sisterD. elder brother37.Which of the following statements is TRUE______A. The mother was sick in bed.B. The aunt didn't like the new baby.C. The new baby was in poor condition.D. The writer loved his family very much.XI enjoy baseball and I like cheering for the hometown team.So my son and I decided to attend an evening of postseason baseball this week when the Arizona Diamondbacks hosted the Los Angeles Dodgers.If you follow baseball,you know the Diamondbacks lost the game...and the series...and their season ended that night.In that regard,the night was a bummer（失望）.But in every other way,the evening was close to perfect.The crowd was cheerful.The weather was amazing.The food was delicious.And the conversation was excellent.We make choices every day with our financial resources（财力资源）.But this particular night of baseball was a helpful reminder to me that experiences are almost always better than things.Experiences result in greater happiness.According to research,experiences result inlonger-lasting happiness than material possessions（拥有）.The happiness provided by new material possessions is short-lived.Over time,people's satisfaction with the things they buy decreases,whereas their satisfaction with experiences over time increases..One reason I enjoy baseball so much,is undoubtedly,because of the many memories I have watching it with my father.Growing up in South Dakota,an annual trip with the family to watch the Minnesota Twins play was a highlight of summer.Decades later,I look back on those moments with great joy and fondness.I remember them far better than almost any of the physical gifts.Experiences result in less clutter （杂乱） .Most physical possessions eventually become a burden on our lives.They take up physical space in our homes and mental space in our minds.Experiences,on the other hand,are accompanied with little to no physical baggage.The only thing I brought home with me from the game were a few photos on my phone. Experiences provide greater opportunity to connect with other people.This is the nature of experiencing things with others.Because we enjoy time together around a common purpose and activity for an extended period of time,we are afforded numerous opportunities to talk and connect with one another. Experiences result in greater mindfulness.In 2010，Matthew Killingsworth and Daniel Gilbert published an important study in Science magazine.Their research concluded that "a wandering mind（不专注的心）is an unhappy mind."And the greater a person's ability to "stay present" in a given moment,the greater happiness they experience during and after.Experiences result in less comparison with others.According to research done by RyanT.Howell and Graham Hill,another significant reason experiences result in more happiness than material possessions is because experiences result in less comparison with others.38.What can we learn from the first three paragraphs？______A. Everything else was enjoyable that night.B. Diamondbacks lost the game in Los Angeles.C. The baseball season was a bummer that night.D. The result of the game cheered the writer and his son up.39.Which could be the first sentence in paragraph 5？______A. Experiences result in happy families.B. Experiences provide better memories.C.

Shared memories bring people closer in a continuing time.41.The writer suggests that we should ______ through experiences.A. stay focusedB. live a full lifeC. enjoy the imperfectionsD. be satisfied with ourselvesYScientists at MIT （Massachusetts Institute of Technology）have managed to change spinach plants into natural sensors which can detect （探测）chemicals used in ing a cheap and small computer system,the spinach can even help send a warning email.The secret to giving spinach these special powers is nanotechnology（纳米科技）.Nanotechnology,or nanotech,is a scientific area that deals with making or changing things that are super tiny.Nanotech is measured in nanometers - one billionth of a meter.The MIT researchers are interested in using nanotech to give plants new abilities.They say plants are already great at sensing their environment,since they take in water from the ground,and react to chemicals in it.Plants also supply their own energy,which the scientists can use to power their tiny experiments.For this experiment,the scientists placed two different kinds of nanotech materials,tiny sensors and carbon nanotubes,into spinach plants.Nanotubes were used to make the plants give off a special light.To get the tiny materials into the plants,the scientists put a-liquid containing,the.nano-materials （包含纳米材料的液体）on the bottom of the plant's leaves.That's where the plants take in carbon dioxide gas.Then the plants took in the tiny materials.Once the tiny sensors and nanotubes were in the spinach leaves,the plant did the rest of the work.The carbon nanotubes in the leaves,using some of the plant's energy,give off a special kind of light.The scientists are able to detect this light by shining a laser（激光）at the plant's leaves and measuring the light.As part of its natural process,the spinach plant pulls water through its roots and into its leaves.If the water contains certain chemicals that are used in bombs,the sensors in the leaves make the nanotubes give off a different kind of light.By watching the plant closely using a camera connected to a cheap computer,the scientists set up a system that can send a warning email if chemicals from bombs are detected in the water. The researchers say it takes about 10 minutes for the plants to react to the chemicals.It is almost like having the plant talk to us about the environment they are in.The scientists say that in the future,their system could even use a cell phone with its camera changed slightly.Detecting chemicals used in bombs is just one of the many uses the researchers are exploring.They've used plants to detect and report on several other dangerous chemicals as well. The scientists believe that in the future,such systems could give farmers detailed information about the health of the land water on their farms.42.Scientists gave spinach plants new skills through ______ .A. powerB. chemicalsC. nanotechD. computer43.Which of the following statements is TRUE about the process of experiment？______A. Nano-materials are put in the roots of the plants.B. Sensors contain special liquid for plants to take in.C. Nanotubes give off tight with the help of carbon dioxide gas.D. Dangerous chemicals are detected by the sensors in the leaves.44.From the passage,we can learn that ______ .A. the energy of the plants helps make it happenB. plants are good at reacting to the environmentC. it takes the plants seconds to notice chemicals from bombsD. scientists are able to see the change in the leaves of the plant45.What can we infer from the passage？______A. Spinach takes in chemicals to make bombs.B. P lants will serve farming better in the future.C. Scientists can improve cell phones with spinach.D. Scientists will put nanotech to other practical use.46.Which could be the best title of the passage？______A. Plants' New Abilities Help Improve Farming.B. Spinach Plants Has Magic Powers to Make Bombs.C. Nanotechnology Taught Spinach to Send Emails.D. Scientists Create Spinach that Can Test for Bombs.47.Experts in the United States have the following suggestions for living a healthier lifestyle：Get active.Ride a bike or walk to places\instead of driving.Cars and other machinesgreatly reduce the need for physical activity.These machines help us move from place to place easily and quickly and work well,but we don't use much physical energy.Eat a well-balanced meal made of protein（蛋白质），grains,vegetables,and fruit.Some people just eat snacks all day.They eat a lot of junk food,such as potato chips and soda.Nutritionists（营养学家）suggest that families eat together.Unfortunately,many people often eat alone and quickly.If families eat their big meal together slowly,they can discuss the events of their day and enjoy their food and each other's company.Take the soft drink and snack machines out of the schools and educate children early about nutrition and exercise.The typical teenager gets about 10 to 15 percent of his or hercalories from soft drinks,which have no nutrition at all.Replace the food in the machines with water,juice,and healthy snacks.Be careful of food messages you hear from advertisers that say,"Eat this.Buy that."Technology allows advertisers to send us messages all the time.Many of these foods are high in fat and calories.Choose natural foods,such as fruits and nuts,instead ofmanufactured（加工的）foods.In addition to what individuals （个人）can do,communities need to build new housing more carefully.In many communities in the United States,it's hard to walk from place to place easily because there are no sidewalks.If we want people to get exercise in theircommunities,they need sidewalks.They also need bike paths so they can ride safely.Change your diet.Eat meat infrequently.Twice a week is chough.Parents need to set a good example so that their kids grow up in a healthy way.How can we get active______What is a well-balanced meal made of______How often should we eat meat to keep healthy______What is the passage mainly about______48.我父母去过上海两次了。
