B.A traveler's journal.C.A news report.D.A trip guide.BIt’s 13:30 and 28-year-old Marten Pella 's smart phone starts pinging, a signal that it’s time for us to stop working around his living room table and instead start our workout routine together. A cartoon character wearing bright red shorts on video begins instructing us to do star-jumps and sit-ups around his apartment.Pella, a research assistant at Stockholm University, is part of the Hoffice movement, which invites workers-freelancers(自由职业者)or full-time employees who can do their jobs remotely—to work at each other’s homes to increase productivity and enjoy an active social life.Those attending Hoffice events advertised on Facebook are typically asked to work silently in 45-minute blocks, before taking short breaks together to exercise, or simply chatting over a coffee. In addition, each participant shares daily objectives with the rest of the group upon arrival, and is invited to report back on whether or not they have achieved them at the end of the day.“Often when I am alone, I can work focused for a couple of hours but then I’m easily distracted(分心).The help of others makes me so much more disciplined.” says Pella, who attends Hoffice events as both a guest and a host. Lunches mean networking and connecting with new contacts. “People are coming from really different areas and have different professions so there can be really interesting discussions,” he says.The Hoffice movement has grown quickly since it was founded in 2014 by Swedish psychologist Christofer Franzen, now 37. He had been giving lectures on the benefits of collective(集体的)intelligence, but realised he was spending most of his own time working alone at his kitchen table. “I wanted to test more structured home co-working with friends in similar situations,” he says.Franzen says that holding events in houses and apartments creates a unique atmosphere, because there’s a sense of community and desire to contribute. He’s looking for ways to expand the social value of Hoffice, bymatching up members with relevant skills to share and even encouraging jobseekers to join its gatherings.4. Where is Pella when his smart phone starts pinging?A. In his own home.B. In his office.C. In another person’s home.D. At Stockholm University.5. What do people attending Hoffice events do first when they meet?A. Watch an exercise video.B. Work silently for 45 minutes.C. Tell each other their daily plans.D. Report what they have achieved.6. What does Franzen really mean by saying “friends in similar situations”?A. They usually work alone.B. They often give lectures.C. They study collective intelligence.D. They have to work at a kitchen table.7. What is the best title for the text?A. Sharing Comfortable WorkplacesB. A New Way to Make New FriendsC. Benefits of Collective IntelligenceD. Working from Others’ HomesCIn the world of Chinese archaeology(考古学), a sign of a dig's importance is the sight of Zhou Mingsheng at work. A field technician who has worked at archaeological sites all aroundChina. Master Zhou iscredited with the gentlest touch in his profession. Born into a farming family, he is a “national-level craftsman” with a talent for using simple tools to get relics(遗物) that wouldcrumblein other hands, says his current boss, Wang Xu, director of an archaeological site at Shuanghuaishu, a Neolithic(新石器时代的) settlement near the Yellow River in the central province of Henan.It is not beauty that attracts visitors to Shuanghuaishu. At 5,300 years old, the settlement is the work of a culture too simple to have left behind many buried treasures. The single most precious find, to date, is a finger-length sculpture of a silkworm. Nor is the setting lovely: an area surrounded by deafening insects, between a highway and two power stations. Rather, the site's importance is historical. For since the birth of Chinese archaeology in the 1920s, it has been inseparable from claims thatChinahas the oldest unbroken civilisation on Earth.Leading archaeologists say that the site has the right combination of location, age and distinctive cultural elements to be the capital of an early Chinese kingdom. That would make it a bridge betweenChina's writtenhistory and the era of the Yellow Emperor, who is said to rule over these central plains almost 5,000 years ago, though many foreign scholars doubt his existence. Chinese media call the site proof ofChina's 5,000 years of history.Foreigners complain about a lack of written records, Mr. Wang notes. Perhaps they are missing symbols that will one day be understood, for instance in patterned pottery. Outsiders “can't keep using Western standards to apply to Chinese ruins,” he argues.8. What does the underlined word “crumble” in Paragraph 1 mean?A. Break.B. Start.C. Wait.D. Shine.9. Why does Shuanghuaishu attract visitors?A. It has appealing scenery.B. It has various precious treasures.C. It is of great historical significance.D. It is easily accessible.10. What is Mr. Wang's attitude towards foreigners’ view?A. Unconcern.B. Disapproving.C. Supportive.D. Not mentioned.11. What does the passage mainly talk about?A. Chinese history amazes the world.B. Chinese archaeology catches on.C. China follows its tradition.D.Chinadigs its past.DA team of researchersfrom theUniversityofColorado Boulderhave created a revolutionary type of robotic muscles. They are strong and flexible at the same time, can feel the movements they perform and, whenever they suffer damage, they can self-heal. However, what is best about them is probably the fact that they are extremely cheap to manufacture.The robotic muscles have been called actuators, and have drawn inspiration from real-life muscles. By creating robots equipped with this kind of actuators, researchers would allowthem to perform movements just like human muscles.To make the robotic muscles work, they filled some flexible material with electrodes(电极)and with liquid and oil. Then, they applied some electricity, and the liquid and oil started moving around the electrodes and powered them. This way, the robotic muscles started contracting and relaxing just like real muscles, but a lot quicker.Researchers also took inspiration from the variety of human muscles, and created more types of actuators, each of them performing a different movement. They called these robotic muscles HASEL ( Hydraulically-AmplifiedSelf-healing Electrostatic). However, they are superior to biological muscles as they are stronger, faster, and more flexible.Even the researchers were amazed they could develop such technology. Eric Acome, the author of one of the studies, explained what is unique about the robotic muscles.“The ability to create electrically powered soft actuators that lift a gallon of water at several times per second is something we haven't seen before.”These muscles are special because they are also self-healing. This property is given by the liquid placed inside of them, which also gives them a lot more advantages than those mechanisms (机械)using solids. In the end, the material which keeps the liquid, the oil and the electrodes is extremely cheap. It is a type of polymer (聚合物)similar to the one used for potato chips bags, and can be manufactures for only 10 cents.12. What can we learn about actuators?A. They can heal on their own.B. They are biological muscles.C. They can not move like human muscles.D. They are slower to react than real muscles.13. What do actuators use to directly power electrodes?A. Solids.B. Liquid and oil.C. A type of polymer.D. Potato chips bags.14. What is the last paragraph mainly about?A. The origin of actuators.B. The opinions on actuators.C. The advantages of actuators.D. The significance of actuators.15. In which part of a newspaper will the textmost probably appear?A. Health.B. Culture.C. Education.D. 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学年中山市纪中三鑫双语学校高三英语上学期期末考试试题及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项ALocated in the beautiful Sichuan Basin, Chongqing is a magical 8D city. The natural history and cultural scenery of the area provide children with learning opportunities because they can enjoy the many wonders of this area.Fengjie Tiankeng Ground JointTiankeng Diqiao Scenic Area is located in the southern mountainous area of Fengjie County. The Tiankeng pit is 666 meters deep and is currently the deepest tiankeng in the world. The scenic spot is divided into ten areas including Xiaozhai Tiankeng, Tianjingxia Ground, Labyrinth River, and Longqiao River. There are many and weird karst cave shafts, and countless legends haunt them.Youyang Peach GardenYouyang Taohuayuan Scenic Area is a national forest park, a national 5A-level scenic spot, and a national outdoor sports training base. Located in the hinterland of Wuling Mountain. The Fuxi Cave in the scenic spot is about 3,000 meters long, with winding corridors, deep underground rivers, and color1 ful stalactites. The landscape is beautiful.Jinyun Mountain National Nature ReserveJinyun Mountain is located in Beibei District of Chongqing City, about 45 kilometers away from the Central District of Chongqing City. The nine peaks of Jinyun Mountain stand upright and rise from the ground. The ancient trees on the mountain are towering, the green bamboos form the forest, the environment is quiet, and the scenery is beautiful, so it is called "Little Emei". Among them, Yujian Peak is the highest, 1050 meters above sea level; Lion Peak is the most precipitous and spectacular, and the other peaks are also unique.Chongqing People's SquareChongqing's Great Hall of the People, one of the landmarks of Chongqing, gives people the deepest impression than its magnificent appearance resembling the Temple of Heaven. It also uses the traditional method of central axis symmetry, with colonnade-style double wings and a tower ending, plus a large green glazed roof, large red pillars, white railings, double-eave bucket arches, and painted carved beams.1.How deep is the Tiankeng Ground Joint?A.666mB.3,000mC.45kmD.1050m2.Which of the following rocks can you see in Youyang Peach Garden?A.LimestoneB.StalactiteC.MarbleD.Quartzite3.Which attraction is closest to downtown Chongqing?A.Fengjie Tiankeng Ground JointB.Jinyun Mountain National Nature ReserveC.Chongqing People's SquareD.Youyang Peach GardenB“My P.E. teacher taught me maths.”It has been a common joke for years but when a P.E. teacher applied for the head-teacher job, many parents worried that “the joke could come true”. Some parents asked, “Does the P.E. teacher know maths and English?If not, how is he supposed to tutor the students?” But there were still parents who believed P.E. teachers had more time to discipline the students since they didn’t have many classes.This concern is actually a “subject bias”, that is, choosing a P.E. teacher as the head-teacher is not good for the students’ grades since he doesn’t know Chinese, maths, or English. It is acceptable for Chinese teachers, maths teachers and English teachers to be head-teachers because these subjects are important to entrance exams and scores. Such a concern reflects parents’ anxiety in the current educational environment, which tends to link the head-teacher’s responsible subject with the facts whether the school cares about the class and the children’s performances in the subject.Many people care about their kids’ academic performances only. They don’t care about their kids’ P.E. performance at all. Even if kids have P.E. classes, parents care little. P.E. teachers are in humble position and their classes are often occupied by other teachers. Of course, if students, P.E. performance is related to grades and entrance exams, parents won’t mind “a P.E. teacher being the head-teacher”.At the moment, P.E. is gradually included in entrance exams.In terms of high school entrance examination,Guangzhouwill launch a new high school entrance exam which includes P.E. performance and Health examination in 2021, raising the score to 70 points.In terms of the college entrance examination, universities having the right of independent enrollments added P.E. tests to their entrance exams in 2019. This practice is seen as an important signal that the assessment of physical fitness and athletic ability, which are important aspects of a student’s overall quality, may be included inthe college entrance examination in the future.We hope that it’s a trend for P.E. teachers, music teachers and art teachers to become head-teachers.4. By saying “My P.E. teacher taught me maths”, what does the author intend to show us?A. It is just a joke that seldom happened in reality.B. P.E. teachers hardly assist students in maths.C. P.E. teachers are good at teaching maths..D. Parents doubt the ability of P.E. teacher.5. We can infer from paragraph 2 that a P.E. teacher .A. is of little benefit for students’ academic performanceB. is humbler than Chinese, math or English teachersC. reflects whether the school cares about the classD. gets unfairly judged due to the current educational system6. Why doesGuangzhouraise proportion of P.E. performance in high school entrance examination?A. To raise students’ awareness of physical health.B. To call on parents to pay attention to P.E. teachers.C. To test the overall ability of high school students.D. To make P.E. teachers equal with other teachers.7. What opinion does the author hold towards P.E. teachers working as head-teachers?A. Neutral.B. Unexpected.C. Supportive.D. Critical.CIt was New Year time, but I wasn’tlooking forward to it. That winter, my mother and my stepfather moved our family toSouthern California. My brother and I were leaving our ruralAlabamabehind. This would be our first New Year away fromAlabama. My mother took toCalifornialike a swan to a royal lake. My athletic little brother, Paul, was keyed up at a climate that allowed him to go to the beach whenever he wanted.I, however, was a fat child with heavy southern pronunciation. My first day in the new class, I introduced myself in a low voice. The moment I opened my mouth to speak, the whole class burst into laughter, “He talks funny.” It was so frustrating that I went to place a call to Granny Smith after school, who was my biggest support, But I didn’t get through.On Sunday evening, the phone rang. It was Granny. She often took advantage of the discounted long-distancerates on Sundays. She said she’d shipped a New Year package. Sure enough, it arrived. Surprised at the box, large enough to hold a small refrigerator, we eagerly tore it open. The smell of Granny’s house filled the room: a combination of fried meat, sausages, furniture polish and decorations. Her house was tiny and always filled withtackyholiday decorations and homemade food before New Year. But in my childhood eyes, it was precious and fantastic.There were countless tins and containers. We open hem to discover piles of holiday treats. She even included our traditional candy bats. The box was as bottomless as a magical box. There, beneath all these, was familiar holiday.Every New Year that we spent inCalifornia, the postal service would call and say our package was arrived. Over the years, many treasures arrived in the box. For me, it’s always been the best part of the holiday.8. How did the author’s brother feel when they were moving toCalifornia?A. Indifferent.B. Joyful.C. Appreciative.D. Disappointed.9. Why did the author’s classmates laugh at him?A. He spoke in a low voice.B. He made a humorous talk.C. He looked overweight.D. He had a strong accent.10. What does the underlined word “tacky” probably mean?A. Suitable.B. Expensive.C. Cheap.D. Attractive.11. Which of the following can be the best title of the text?A. Granny’s Care PackageB. An UnforgettableHolidayC. Our Move toCaliforniaD. A Telephone Call from GrannyDPablo Picasso was born on October25 inMalaga. Spain in 1881. Taking after his father, Picasso shared apassion(热爱)for painting and art. Even though he wasn't the best student in school, Picasso excelled at drawing. Noticing his amazing talent, Picasso's father, an artist, taught him everything he knew. Before long, Picasso could paint and draw much better than his father. With this rich talent, Picasso paid less and less attention to his schoolwork and spent the majority of his day sketching and drawing in notepads and sketchbooks.When he was a little bit older, Picasso moved twice and was accepted into two fine art programs. However, he didn't care very much for the special techniques they taught and often wandered the streets by himself drawing the scenes around him. After moving to these two places, Picasso moved back home toBarcelonaand decided that he would develop new techniques of art and painting based on what he saw.Later, Picasso decided to move toParis,France, where he began perfecting his own techniques of painting, drawing and other forms of art. His drawings. paintings, and an included pieces about sadness, poverty, classics and self-portraits. One of his major types of work is calledcubism(立体派),which includes art with all sizes of geometric shapes together on the piece of an. This type of art is very important because no other artists had come up with the idea before. Picasso decided to try something new, and as a result, cubismis widely accepted today as a classic style of art.Picasso inspires us to always be thinking. He tells us to think outside the box and come up with fresh new ideas that can change the world. He surely plays a significant role in the art field.12. What do we know about Picasso as a student at school?A. He hated doing his homework.B. He was very proud of his talent.C. He showed great talent for drawing.D. He was often praised by his teacher.13.

He encouraged Picasso to do better at school.14. What was Picasso's attitude towards the special techniques at that time?A. He thought highly of them.B. He took no interest in them.C. He was confused about them.D. He was concerned about them.15. What does the author tell us in the last two paragraphs?A. Picasso has great faith in art.B. Picasso has changed the world a lot.C. Picasso can do anything he wants to.D. Picasso is a highly creative artist.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。
