And the noisy situation and endless housework may result in a terrible emotion. A new option is waiting foryou. That is WFH: work from a hotel.Hotel FigueroA special program titled Work Perks aims to reposition some of 94-year-old Hotel Figuero’s 268 rooms as day-use offices.According to Managing Director Connie Wang, the set-up launched in June and is a great opportunity to get out of their houses with high-speed Wi-Fi, unlimited printing privileges and free parking. The 350-square-foot rooms sell for $ 129 per day, with an option to extend to an overnight stay for an additional $ 20.The WytheA boutique hotel in Brooklyn. The hotel recently announced a partnership with co-working office space company Industrious through which it is recycling 13 second-story guest rooms to serve as offices for up to four people.Each of the rooms has a small outdoor platform, and dogs are welcome. Pricing starts at $ 200 and goes up to $ 275, depending on how many people use the space.The SawyerThe Sawyer, in Sacramento, California, is offering pool cabanas (更衣室) for use as outdoor offices, complete with fast Wi-Fi, free parking and catered lunch for $ 150 per day.HotelsByDayYannis Moati founded HotelsByDay back in 2015. That company has grown to include more than 1,500 hotels, and has seen a significant increase in the number of inquiries for day-use bookings lately.Moati said the current situation will force hotels to upgrade themselves to stay alive, and he predicted that offering rooms for day-use only is one of the directions they will go.1.How much should one pay for a 24-hour stay in Hotel Figuero?A.$ 129.B.$ 149.C.$ 150.D.$ 200.2.Which hotel allows pets in?A.The Wythe.B.The Sawyer.C.HotelsByDay.D.Hotel Figuero.3.What do we know about Yannis Moati?A.He started a program titledWork Perks.B.He has upgraded at least 1,500 rooms.C.He usually predicts everything correctly.D.He is optimistic about the WFH trend.BDragon boating is a team sport that has its root in ancient China. The boats are decorated with a dragon head and tail. In recent years cancer survivor groups have got involved in the sport to help make friends and help rebuild their lives.On a recent Saturday morning, a group of 20 women were on a boat in the Anacostia River in Washington DC. They moved their paddles(船桨)in rhythm to the call of a coach. The women belong to the dragon boat team GoPink! DC, which trains weekly. It also races against other breast cancer survivor teams in dragon boat festivals. As a result, GoPink! DC won medals in this Washington dragon boat festival.Lydia Collins joined five years ago after finding out she had breast cancer. “I was diagnosed with breast cancer.I was demoralized because of my illness - I lost all interest in life and wouldn't even get out of bed to eat. But now I love the team spirit. I just love everything about it. It is like a floating support group on the water.”The paddles are breast cancer survivors and their supporters. Annette Rothemel helped establish(建立)the group in 2006. She is a researcher with the National Institutes of Health as well as a breast cancer survivor. “It is sort of an easy entry sport because on the same boat people at different levels can be doing the same sport.” But Ms Rothemel saysdragon boating can be physically demanding, especially for someone who is sick and getting treatment for cancer.“It’s hard but I think you have to challenge yourself in life. This is something I look forward to. I get to be out here with my sisters and supporters that understand what I’m going through and help motivate me. So it makes me stronger and it makes me feel better,” another cancer survivor Rhonda Hartzel said.Annette Rothemel says the cancer survivors feel a sense of sisterhood and share good times when they paddle together. She says both feelings are treasured by the team.4. What do the underline wordsdemoralizedIn para.3 probably mean?A. depressedB. anxiousC. astonishedD. awkward5. What can we know about Lydia Collims from the text?A. she helps establish Go Pink !DCB. she tries to find a cure for the cancerC. she benefits from the dragon boat raceD. she gives up hope because of her illness6. How can the dragon boat race help the cancer survivorsA. forget their tough experiencesB. recover physically and mentallyC. get rid of the pains of their cancerD. enjoy their rest life without sufferings7. What does the text tell us about Annette Rothemel?A. she is an expert in studying the cause of the cancerB. she helps the cancer survivors in financial difficultiesC. she believes there is a healthful result from the dragon boat raceD. she thinks it unwise for the patient to join in the dragon boat raceCEvery racehorse has different abilities．Like humans，some are short- distance runners，while others are marathoners．Figuring out which is which and how to pace them can be the difference between failure in the finish and taking the award home．Jockeys（赛马骑师）and trainers have traditionally relied on centuries of experience and data from previous races to plan their races．Amandine Aftalion，a mathematician in Paris，thought she could add to that．Since 2013，she has been analyzing the performances of world champion runners like Usain Bolt．She has found that short-distance runners tend to win when they start strong and gradually slow down toward the finish line．Butin medium-distance races，runners perform better when they start strong，settle down，and finish with a burst of speed．Her model shows how those winning strategies maximize the energy output of muscles reliant on two different pathways：powerful aerobic（有氧的）ones that require oxygen，which can be in limited supply during a race，and anaerobic ones，which don't need oxygen but build up waste products that lead to tiredness．Aftalion wondered which strategy would be best for horses．So she and Quentin Mercier，anothermathematician，took advantage of a new GPS tracking tool inserted in French racing saddles（马鞍）．The two studied patterns in many races at the Chantilly racetracks north of Paris and developed a model that accounted for winning strategies for three different races：a short one(1，300 meters)，a medium one (1,900 meters)，and a slightly longer one (2,100 meters)，all with different starting points on the same track．The model takes into account not just different race distances，but also the size or friction fromthe track surface．The results might surprise jockeys who hold horses back early for bursts of energy in the last finish．Instead，a strong start leads to a better finish，the team found．“That doesn't mean those jockeys are wrong，though．If the start is too strong，it can bedevastatingas well，leaving the horse tired by the end，” Aftalion says．8. What should a runner do to get an award according to the text?A. Make a good start．B. Plan for the race early．C. Run slowly on the starting line．D. Try runningquickly all the time．9. What formed the basis for Aftalion's studying horse race?A The experience and data from previous horse races．B. The benefit of knowing horses' different abilities．C. The success in studying runners' winning strategies．D. The performance of horses on different race distances．10. What does the underlined word“devastating”in the last paragraph mean?A. Boring．B. Damaging．C. Astonishing．D. Puzling．11. What can we infer from the text?A. Runners have the same energy output of muscles．B. Aftalion's findings may help horses to win the race．C. What Jockeys and trainers do makes no sense to horses．D. World champion runners made a contribution to the study．DI don’t think I can recall a time whenI wasn’t aware of the beauty of the ocean. Growing up inAustralia, I had the good fortune of having the sea at my side. The first time I went toHalfmoonBay,I suddenly had the feeling of not being able to feel the ground with my feet anymore.For my 10th birthday, my sister and I were taken out to theGreat Barrier Reef. There were fish in different color1 s, caves and layers of coral. They made such an impression on me. When I learned that only one percent ofAustralia’sCoral Seawas protected, I was shocked. Australian marine (海洋的) life is particularly important because the reefs have more marine species than any other country on earth. But sadly, only 45% of the world’sreefs are considered healthy.This statistic is depressing, so it’s important for usto do everything to protect them. The hope that theCoral Searemains a complete ecosystem has led me to take action. I’ve become involved with the Protect Our Coral Sea activity, which aims to create the largest marine park in the world. It would serve as a place where the ocean’s species will all have a safe place forever.Together, Angus and I created a little video and we hope it will inspire people to be part of the movement. Angus also shares many beautiful childhood memories of the ocean as a young boy, who grew up sailing, admiring the beauty of the ocean, and trying to find the secrets of ocean species.12. What can we learn about the author from the underlined sentence inPara. 1?A. He seldom went surfing at the sea.B. He forgot his experiences about the ocean.C. He never went back to his hometown.D. He had a wonderful impression ofHalfmoonBay.13. What is Australian marine life like according to the second paragraph?A. It is escaping from theCoral Seagradually.B. It depends on reefs for living greatly.C. It may be faced with danger.D. It is protected better than that in other oceans.14. What’s the purpose of The Protect Our Coral Sea activity?A. It is intended to contribute to a complete ecosystem.B. It is intended to prevent more marine species being endangered.C. It is intended to set up a large nature reserve for reefs.D. It is intended to raise more teenagers’ environmental awareness.15. Why do Angus and the author create a little video?A. To urge more people to take action toprotect the marine species.B. To inspire more people to explore the secret of the ocean.C. To share their childhood experiences about the ocean.D. To bring back to people their memory of ocean species.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。

Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out．Study participants view a carbon footprint label as similar to labels that have appeared on some existing products．The label shows the carbon dioxide emissions connected with their production, transportation, usageand disposal（清理）, thus showing the buyer the likely effect on climate change of buying a particular product．In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price．In a second set of studies, the team found that emissions connected with usage were most important to consumers followed by the transportation and disposal stages．The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's lifecycle because it is outside the consumer's control．That is, the participants felt they were less responsible for carbon emitted during producing process．Consumers value recycling a product, but the researchers found that, overall, the consumers would preferproducers to offset（补偿）carbon emissions rather than having toaddressthe problem directly themselves．Consumers are increasingly concerned with climate change problems, and already carbon labeling is appearing on some products．"We find that participantsnot only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain．They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice．8. Which of the following most affects consumer's choice?A. Labels．B. Price．C Packaging． D. Carbon footprint．9. About the carbon dioxide emissions in the product's lifecycle, which stage do consumers care most?A. Usage stage．B. Transportation stage．C. Disposal stage．D. Producing stage．10. Which of the following can best replace the underlined word "address"?A. Look into．B. Point out．C. Deal with．D. Run into．11. What can be inferred from the last paragraph?A. Companies should take carbonemissions more seriously．B. All products have been labeled with carbon emissions data．C. Producers will attach less importance to carbon emissions labels．D. Products labeled with carbon emissions data will have poor sales．DElizabeth Bishop is considered one of the best American poets of the 20th century. She was born in Worcester, Massachusetts in 1911. Her dad died when she was just a baby and her mom never recovered from the loss. Shewent to live with her grandparents in Nova Scotia, Canada when she was five. Eventually Bishop attended Vassar College, where she began to write poetry.At Vassar she discovered Marianne Moore's poetry and met Ms Moore and began their life-long friendship. She later met poet Robert Lowell. She wrote tons and tons of letters to both of them, which is good for us because we would otherwise know very little of her personal life.Bishop published her first book of poetry in 1946 and wrote until her death in 1979. She would spend years working on a single poem. Her poems are not the result of hasty scribbling (匆忙乱写) on paper while eating breakfast. She would look through drafts of poems again and again and improve them until they were as close to perfect as she could get them.Reading Elizabeth Bishop is like being transported to the very place, the very moment she's writing about. She leads us to a microscope so we can see every smallest part of the scene. It seems that she's always asking us to notice more, and more until the poem is so clear in our minds that it's almost painful—like a light that's too bright.12. What do we know about Bishop's early life?A. She was mainly brought up by her grandparents.B. She spent her childhood mainly in Worcester.C. She was always encouraged by her parents.D. She started to write poems at five.13. Why are Bishop's letters to Moore and Lowell important?A. They have a deep influence on other poets.B. They offer much information about her life.C. They help us study Moore and Lowell's poetry.D. They prove she had friendships with famous poets.14. What can we say about Bishop's poetic creation?A. She liked to write in the morning.B. She could write poems at high speed.C. She tried her best to achieve perfection.D. She published hundreds of books of poetry.15. Which word can be used to best describe the style of Bishop’s poems?A. Enthusiastic.B. Romantic.C. Humorous.D. Exact.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。

北京市朝阳区北京八十中学2024学年高三3月7号月考语文试题试卷含解析

北京市朝阳区北京八十中学2024学年高三3月7号月考语文试题试卷请考生注意：1．请用2B铅笔将选择题答案涂填在答题纸相应位置上，请用0．5毫米及以上黑色字迹的钢笔或签字笔将主观题的答案写在答题纸相应的答题区内。

写在试题卷、草稿纸上均无效。

2．答题前，认真阅读答题纸上的《注意事项》，按规定答题。

1、阅读下面的文字，完成下列小题。

中国在2001年前几乎没有世界级的超算产品，因为构建一整套全球顶级的超算系统，也并非堆砌处理器这么简单。

中国超算研发的全面崛起，是建立在强有力的计算个体芯片、先进的运算管理技术和可靠的操作系统支持基础之上的。

芯片无疑是超级计算机的核心部分，一台超算产品至少装有几千枚甚至数万枚CPU和GPU芯片，同时配备特殊的操作系统，负责管理这些芯片之间如何合作，进行一系列复杂的运算，才能真正使之拥有十分可靠的强大算力。

国防科技大学分别在2010和2013年建造的“天河一号”和“天河二号”超级电脑，都曾登顶世界超算TOP500榜单，两者都主要使用Intel和AMD提供的芯片。

2015年4月，美国政府宣布制裁中国四家超算中心，禁止向中国超算中心出售Intel的Xeon Phi超算芯片。

天河二号就因为美国的制裁，耽搁了升级计划，不得已调整技术路线，并且采用国产矩阵2000替换Intel的Xeon Phi。

但这无法阻止中国超算研发的强势崛起。

2017年，广州超算中心宣布使用国产矩阵2000芯片，升级了天河二号超算系统，并成功实现算力翻倍。

而神威·太湖之光超级计算机起初就安装了40960个中国自主研发的“申威26010”众核处理器，而且性能不俗。

多年以来，计算机CPU芯片一直遵循摩尔定律进行升级迭代。

但摩尔定律也是有极限的，集成电路上的元器件已经足够小，己经逼近“原子尺度”了。

很难再延续过往路径进行升级迭代。

这个时候，就要想办法挖掘计算机的系统潜力。

在挖掘计算机系统潜力方面有两个思维路径：一个是阿里方案，一个是联想方案。

This new research on space weather timing allows predictions to be made for extreme space weather. Therefore, it could be used to plan the timing of activities, which could be affected by extreme space weather, for example, major space missions.The researchers found for the first time that extreme space weather events are more likely to occur early in or late solar cycles-such as the one just starting. The findings may have influences on the NASA-led Artemis mission. It plans to make humans return to the moon in 2024, but can be put off to the late 2020s.Professor Mathew Owens, a space physicist at theUniversityofReading, said, “Until now, the most extreme space weather events were thought to berandomin their timing. Though there is no set pattern of the events, this research suggests they are more predictable.”In the new study, the scientists used a new method applying statistical modelling to storm timing for the first time. Previous research generally focused on how big extreme space weather events can be, based on observations of previous events. Predicting their timing is far more difficult because extreme events are rare, so there is ly little historic data to identify patterns. The findings suggest that any major planned space missions , which is beyond the next five years, will have to consider the higher probability of extreme space weather late in the present solar cycle between 2026 and 2030.4. What can we learn about the study from the first two paragraphs?A. It has lasted just 150 years.B. It doesn't refer to space weather data.C. It shows space weather has no effect on astronauts.D. It makes it possible to predict extreme space weather.5. Why might the NASA-led Artemis mission be put off?A. To research solar cycles.B. To avoid effects of space weather.C. To meet the needs of the astronauts.D. To make humans return to Earth in 2024.6. What does the underlined word “random“ in paragraph 4 probably mean?A. Irregular.B. Easy.C. Limited.D. Changeless.7. What can we infer from the last paragraph?A. The study is useful for future space missions.B. The planned space missions should be put off.C. Extreme space weather will happen before 2026.D. Previous observations make no difference to the study.CI don’t want to talk about being a woman scientistagain. There was a time in my life when people asked constantly for stories about what it’s like to work in a field dominated (controlled) by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space, time and the nature of black holes.At 19, when I began studying astrophysics (天体物理学), it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement — jobs, research papers, awards — was viewed through the lens (镜片) of gender (性别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus (相对于) right brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply to any and all provocations (挑衅): I don’t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn’t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don’t study sociology or political theory.Today I research and teach at Barnard, a women’s college in New York City. Recently, someone asked me howmany of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45.I know some of my students worry how they will manage their scientific research and a desire for children. And I don’t dismiss those concerns. Still, I don’t tell them “war” stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that’s a sight worth talking about.8. Why doesn’t the author want to talk about being a woman scientist again?A. She is fed up with the issue of gender discrimination (歧视).B. She feels unhappy working in male-dominated fields.C. She is not good at telling stories of the kind.D. She finds space research more important.9. From Paragraph 2, we can infer that people would attribute (把……归因于) the author’s failures to ________.A. the burden she bears in a male-dominated societyB. her involvement in gender politicsC. her over-confidence as a female astrophysicistD. the very fact that she is a woman10. What did the author constantly fight against while doing her Ph.D. and post-doctoral research?A. Lack of confidence in succeeding in space science.B. Unfair accusations from both inside and outside her circle.C. People’s fixed attitude toward female scientists.D. Widespread misconceptions about nature and nurtured.11. What does the image the author presents to her students suggest?A. Women students needn’t have the concerns of her generation.B. Women can balance a career in science and having a family.C. Women have more barriers on their way to academic success.D. Women now have fewer problems pursuing a science career.DImagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, alarming you to any traffic, pedestrians,animals, or other things nearby. Routes and names of roads appear over the live stream. It's like the map has come to life.This type of map isn't available yet. But it could be soon. In 2014, the Worldview-3 satellites was launchedinto space. Even though it orbits Earth at more than 370 miles（600 km）away, it can capture images of objects on Earth that are just 10 inches（25cm）across.Peeringall the way from outer space, it can make out a smartphone held in your hand. It can tell what types of cars are traveling down a road. But it can't identify your face or read the cars' license plate numbers . . . at least not openly.According to some reports, this satellite and other US spy satellites have the technology to take even sharper images, with a resolution（分辨率）of up to around 4 inches（10cm）. ButUS law forbids making these super-sharp pictures public, to prevent enemies from using them. But the idea that anybody might be able to spy on the entire Earth in such detail may seem horrible. Live, high-detail satellite mapping could possibly be used to monitor anybody at any time. Ray Purdy of University College London told CNN that he is concerned about what this could mean for privacy. Most satellites are commercially owned, so if you have money you can buy that imagery. “It means anyone can spy on anyone,” he said.At the same time, live, detailed maps of Earth's surface could be useful in amazing ways. Live maps of a disaster area could quickly discover people in need of rescue as well as the safest routes in or out. Satellite images are already helping catch illegal logging and fishing operations. Higher detail may make it possible to catch other criminals in the act. The images could also make it easier for farmers to watch over their crops.What do you think? Do you wish everyone could access high-detail live maps of Earth's surface?12. What does the underlined word in paragraph 2 mean?A. SeeingB. StandingC. WalkingD. Hearing13. Why does US law forbid making super-sharp pictures public?A. to protect the technology.B. for the sake of safety.C. to protect the environment.D. to threat other countries.14. Which of the following statements is true according to the text?A. This super-sharp map hasn't been put into market.B. Worldview-3 satellites orbits the Earth at 370 km away.C. Personal privacy is safely protected if you use the super-sharp map.D. The super-sharp map should be completely forbidden.15. How is this technology used in agriculture?A. It can help improve the production of crops.B. It can help kill pests.C. It can help farmer to watch over their crops from far away.D. It can help increase farm land.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2021届北京市第八十中学高三语文月考试卷及答案

2021届北京市第八十中学高三语文月考试卷及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成下面小题。

牵风记（节选）徐怀中“野政文工团”派出一个小分队，来九团慰问演出。

思想内容没得说，可是出来进去总是那么几个熟悉面孔，太乏味了！台下开始发难:“不看！不看！不看！”最初只有少数人起哄，像是受到恶性传染，到处尖声刺耳地打起了口哨。

报幕人从大幕中缝处钻出来，他每次出现，观众都以为演出将会做出重新调整。

台下又狂呼乱喊起来:"出来一个坤角儿！出来一个坤角儿!"宣传队队长亲自到大幕前讲话，面目严肃到不可能更加严肃：“我可以负责地向你们声明，我们这里没有什么坤角儿，绝对没有! ”“有!”“有!”台下齐声揭露。

小分队里确实有两位女演员，可是今晚排定的节目单里没有女角，分派她们俩反串鬼子兵。

团长齐竞接到报告，风风火火地赶来了。

有人认出了团长，彼此提醒：“一号！”“一号！”前面几排观众端端正正坐好了，远处的人似乎觉察出有什么不对头，也都不敢再出声了。

齐竞这才开始队前训话:“丢人现眼！给八路军丢人现眼！给'虎团'全团将士丢人现眼!”全场空气像是凝结在一处，紧张极了，大家都听到自己的心咚咚地跳。

齐竞转身向当值的现场总指挥挥手说:“解散！各单位带回！”老乡们叹息说，可惜一台好节目，就这样吹灯拔蜡了。

"请等一下！请等一下!"传来一个女孩子的呼喊声。

“虎团”团长齐竞远远看到，那个女孩子站在场地最后，一只手抱着长长的一个什么物件。

她很有自信的样子，脸上总挂着那么一丝天然的微笑。

女孩仰起脸，向高居于舞台台口的齐竞提出交涉:“首长同志，你好！碰巧我带着古琴，就由我为大家弹奏一支曲子可以吗？”一个花季少女怀抱古琴，突然出现在队列前，齐竞简直不敢相信自己的眼睛了。

陪同女孩子的地方干部上前说明，她是从北平来的女学生，名叫汪可逾。

路经此地，正好赶上"虎团”在开晚会。

2021年北京市第八十中学高三英语月考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AMirroring body language is a way to bond and to build understanding, It is a powerful tool that we use without even knowing it.The most obvious forms of mirroring are yawning and smiling. When you seesomeone yawn, you are likely to yawn immediately. Smiling is also prettycontagious—seeing a smiling person makes you want to smile too.Mirroring body language is a nonverbal way to say “I am like you, I feel the same”. Research shows that people who experience the same feelings are likely to trust, understand and accept each other.Women have the natural ability to pick up and understand body signals. Therefore, it is not surprising that a woman is more likely to mirror another woman than a man is to mirror another man. That's why women are regarded as better talkers, even if they might not really have more close friends.It is interesting that when a man tries to mirror a woman's body language while she is talking, he may seem to her as caring, intelligent and attractive.Mirroring body language is an excellent way to build trust and understanding quickly. If you want to set up a connection with a new person, mirror his or her gestures, sitting position, tone of voice and talking pace. This will make them feel that there is something about you that they like.While mirroring body language gains you acceptance, you still need to take into consideration your relationship with the person you arc mirroring. If you are in a lower social position and are mirroring the body language of your boss, he will view you as arrogant. However, if you want to defeat those who are trying to prove superior to you, mirroring their body language will help defeat them and change their position.1. What does the underlined word “contagious” in paragraph 2 mean?A. Powerful to show one's feelings.B. Affecting each other.C. Attractive to the others.D. Being gentle to people around.2. When copying others, body language, one usually can ______.A. send wrong messagesB. hide true feelingsC. avoid misunderstandingD. win others, acceptance3. What might happen if you try to mirror your boss's body language?A. You will appear very attractive.B. It will help to soften his position.C. You will seem unacceptably proud.D. It willbe a good way to build trust.BWhether for a special holiday, as a way of showing gratitude or just a way of letting someone know you care, gift giving is a universal custom Though the purpose may be similar from place to place, traditions vary widely from one country to the next. A behavior that shows respect in one place might be consideredoffensivesomewhere else. Take a look at unique gifting traditions from around the world.Here in theUS, a set of kitchen knives seems like the perfect gift idea for a wedding. However, in certain European countries likeGermany, people believe that a knife presented as a gift will cut off your friendship. There is a way to break it: Tie a coin to the knife or gift box. The receiver then returns the coin to you as a “payment”to remove the bad luck.There's a well-known Italian wedding tradition where the groom's (新郎) tie is cut into a number of tiny pieces. Wedding guests can then "buy” these tie pieces in exchange for cash. It's a fun way to give money to the new couple thatleaves guests with a wedding souvenir.As left hands are considered unclean in Indian culture, behaviors such as touching, passing money, or giving gifts are to be done with the right hand. Different from some other cultures , an odd number (奇数) of thingsor currency represents good luck. For example, £11 should be given rather than £10.InZimbabwe, it is common to directly ask for a gift. When you receive a gift without asking for it, even if the giver's family is poor, it's the worst way to reject the offering. Also, expressing thanks with actions is better than giving thanks orally (口头地).These may include jumping up and down, dancing, or whistling.4. What does the underlined word “offensive“ in paragraph 1 refer to?A. Rude.B. Creative.C. Suitable.D. Caring.5. How do people prevent friendship breaking down when giving gifts like knives?A. The guests cut the groom's tie into pieces.B. The receiver returns the coin to the giver.C. The giver gives gifts with the right hand.D. The receiver expresses thanks by dancing.6. What can we learn about the gift giving inZimbabwe?A. It is not proper to ask for a gift directly.B. It's better to reject a gift from a poor family.C. One can express thanks by writing letters.D. Showing gratitude with actions is better than words.7. Which can be a suitable title for the text?A. The Wayof Showing GratitudeB. A Fun Behavior to Respect PeopleC. Various Gift Giving TraditionsD. A Special Custom of Gift GivingCByteDance（字节跳动）Group’s TikTok, an overseas version of Chinese short video sharing app Douyin, faces an existential crisis in the United States, as murmurs of a “crackdown”（强制取缔）from the White House forced the Chinese company toengage in talks on selling its US business to Microsoft.TikTok is the fastest-growing registered global mobile internet app, with more than 100 million users, and its rapid growth, especially in the US, is seen as a threat to Facebook. The US government has long viewed globally competitive Chinese high-tech companies including Huawei as a threat and done whatever it could to crack down on（打击）them in the name of “national security”.The US government has not introduced any specific policy against TikTok only threatened it through a number of unclear statements.According to the latest media reports, Microsoft is prepared to press ahead withthe negotiations to take over TikTok’s US operations and complete the negotiations by Sept 15, following talks between Microsoft CEO Satya Nadella and US President Donald Trump.This means that TikTok will have to hand its fate over to some unpredictable power, and even have to sell its assets without the option of setting a price.The US government has failed to find a reasonable legal excuse to deal with TikTok. All private data of TikTok’s US users are stored in the US and are unlikely to be transferred. Considering the US government is trying to deal with TikTok in a political way, TikTok should consider incorporating（合并）the dispute into the US legal process to assert（坚持）its legal rights and interests.TiKTok’s core value lies in its unique algorithms,a product of artificial intelligence that represents the expertise of Chinese engineers and programmers with high-value intellectual property.The US government’s move, which has forced ByteDance to sell TikTok to a US company, is similar to a forcedtechnology transfer and an example of the US’ openseizureof Chinese intellectual property.If ByteDance sells TikTok to a US company for “security reasons", that would set a dangerous precedent, motivating other countries where TikTok operates to follow the US administration's example and cause a chain reaction.ByteDance is a young Chinese private company that cannot deal with a political game played by the US. But as a Chinese company that has gone global, ByteDance has reasons to take up legal means to defend its legal rights. The Chinese government can also consider examining whether the technology transfer in the deal violates China’s law and harms the country’s national interests.8. What is the most valuable as for TikTok?A. Its global popularity.B. Its artificial intelligence.C. Its registered global mobile internet app.D. Its private data of TikTok’s worldwide users.9. Why does the American government force the Chinese company to hand over TikTok’s US operations to a US company?A. Out of so-called political reasons.B. Out of so-called debt reasons.C. Out of so-called technical reasons.D. Out of so-called security reasons.10. What does the underlined word “seizure”probably mean in Para. 8?A. An untrue spoken statement about someone.B. The use of legal authority to take sth from sb.C. The crime of stealing sth from a person or place.D. The act of trying to hurt somebody using physical violence.11. What can be the best title for the news report?A. TikTok must defend its rights legallyB. TikTok is seen as a threat to FacebookC. ByteDance has to sell TikTok to a US companyD. ByteDance agrees to transfer technologyDSophie became friends with the gray squirrels during her first week atPennState, after spotting them running around and wondering what they would look like with tiny hats on their heads. Today, everyone at the universityknows her as the “Squirrel Girl”.Sophie tried bringing them food, and gradually they began to trust her. She managed to put a hat on a squirrel and take a picture. Thinking that her colleagues could do with something to lift their spirits, she started posting similar photos on Facebook. The response was greatly positive, and before long Sophie and her squirrels became an Internetsensation.Growing up in a neighborhood outside ofState College, Sophie was always fond of birds and animals around her home, but she didn't interact with people very much. She was later diagnosed (诊断) with Asperger's syndrome, but the squirrels changed that. “The squirrels help me break the ice, because I'll be sitting here patting a squirrel and other people will come over and well just start like feeding the squirrels together and chatting about them,” she said, “I am a lot more outgoing.”And in case you're wondering how Sophie is able to get the squirrels to do what she wants for her photos, it has a lot to do with food. For example, whenever she wants them to hold or play with something, she puts peanut butter on the prop (道具), and they'll grab it. In the beginning, she would throw peanuts up the trees on campus and invite the squirrels to come down and get them, but they hesitated to approach her. She had the patience to earn their trust, though.This year, Sophie is graduating with a degree in English and wildlife sciences. She wants to be a science writer and educate people on how to preserve the environment. As for her furry friends, Sophie plans to stay in the area and visit them as often as she can.12. What does the underlined word “sensation” in paragraph 2 mean?A. Event.B. Hit.C. Service.D. Addiction.13. What can we learn about Sophie according to paragraph 3?A. She got lots of friends due to squirrels.B. She used to be a popular girl in her childhood.C. She lived in the far countryside when young.D. She was more outgoing than before.14. How did Mary manage to take photos of squirrels wearing hats?A. By attracting them with food.B. By putting them in cages.C. By playing music to them.D. By dressing like squirrels.15. What do you think of Sophie?A. Tolerant and capable.B. Sociable and aggressive.C. Patient and caring.D. Indifferent and appreciative.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。
