2019-2020学年房山中学高三英语期末考试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APersonal Time Off(PTO)is something my wife and I created after having kids. We learned that，over time，a full life can leave little time for personal rest and for reflection，hanging out with friends，or just being“off. ”So，after a number of years，we make a change. If I can persuade you to take your own PTO，then these might help.■Schedule itFirst of all，one of our favorite family sayings is“schedule it. ”Sounds easy enough，but life gets complicated managing full-time work and full-time family. Put yourPTO time on the calendar and you make it a real thing.■Be flexible and strictIf you can schedule PTO at the same time each week，then all the better. Because our calendar can get rather full，flexibility in scheduling becomes a necessity. But being strict in actually taking the time each week is more important. Skipping it once makes it easier to skip again.■Take enough timeMy typical PTO lasts a couple of hours or longer. Sometimes it might be half the day depending on what I’m doing. The goal is to spend enough time away to1et your shoulders drop.■Do what you want to doRemember，PTO time is about personal time to do what you want to do，not what you have to do. PTO time is about relaxation. Grab a friend and get a beer. Work can wait until tomorrow.1.What can be the first step to take the PTO?A.Persuade the family.B.Have a personal rest.C.Ask friends for advice.D.Make a time plan.2.What does the underlined part“let your shoulders drop”probably mean?A.Get you more focused.B.Have you feel relaxed.C.Shake your shoulders often.D.Make you feel more stressed.3.What does the text mainly talk about?A.Tips on how to take your time offB.Skills to manage work and familyC.Advice on how to free yourselfD.Ways of scheduling your workBOnce a rich and clever boy had practically everything a boy could want, so he was not interested in most toys. But he couldn't get a very old mirror, and heconvinced his parents to buy it from mysterious（神秘的）old man. When the mirror arrived home, the boy went to see his reflection in it. His face looked very sad indeed. He tried smiling and making funny faces, but his reflection continued with its sad expression. "What a terrible mirror! It's the first time I've seen a mirror that didn't work properly!" the boy jumped violently.That same afternoon he went into the street to play and bought a few toys, but on his way to the park he saw a little girl who was crying her heart out. The girl was crying so much and looked so lonely that the rich boy went over to help her and to see what had happened. The little girl told him that she had lost her parents.Together the two set off in search of the parents. As the little girl wouldn't stop crying, the boy spent his money buying her sweets to cheer her up. Finally, after much walking, they found her parents who were much worried and were looking for her everywhere.The rich boy said goodbye to them. As it was getting late, he decided to head for home, without being able to play. At home, he went to his room, and noticed a shining light in the corner, the same corner he had left the mirror in. Seeing this, he went over to the mirror, and realised that the light was coming from his own body, so radiant（闪亮的）with happiness he had become.And so he understood the mystery of that mirror, the only mirror which could faithfully reflect the true joy of its owner. He realised it was true. He felt very happy at having helped that little girl. And since then, each morning when he looked in that mirror and failed to see a special shine, he knew what he had to do to bring it back.4.

To warn us not to be selfish.D. To encourage us to help others.CIn Colombia a group, named WebConserva, is carrying out a project in the San Lucas Mountains with the help of coffee growers.The San Lucas area is one of the most unexplored places in Colombia, which is home to many thousands of species of animals and plants. Yet gold mining and coca farming have dealt a blow to its ecosystem. To limit additional development in the San Lucas area, the group helps coffee growers by linking them with processors from around the country.Colombia has more different kinds of living things than any other country except neighboring Brazil. In 2016, the Colombian government signed a peace deal with the Revolutionary Armed Forces of Colombia ending years of civil war. As a result, more land became accessible for use, with deforestation(毁林) coming along. Government information shows that in 2017, almost 220,000 hectares of forest were destroyed compared to around 124,000 hectares in 2015.To date, the project includes 10 families who farm 400 hectares of coffee plants, which costs about $77,000 dollars a year. WebConserva hopes that, in time, 200 families will be included. At that level, 20,000 hectares of untouched forest could be protected. In San Lucas, the families promise not to cut down trees to expand their crops or to hunt wild animals from the forests. In return, they receive $ 250 to $ 300 per 125 kilograms of coffee, an enviable amount there. Arcadio Barajas is among those taking part. His new coffee plantation(种植园) makes a barrier between cattle farms and forests where wild animals like the jaguar live and hunt. In this way, he doesn't have to kill wild animals to protect his cattle.Barajas said that pulling down the forest to plant coca and killing wildlife were against his will. Now he feels that growing coffee lets him be astewardof the land. "I'm taking care of the environment, the forest and the animals," he said.8. Why does WebConserva set up the project?A. To help local farmers make money.B. To expand areas of coffee growing.C. To link processors with coffee growers.D. To conserve biodiversity in the Mountains.9. What happened after Colombia’s civil war was over?A. Colombia helped many needy families.B. Colombia lost lots of areas of forests.C. Colombia started to save damaged forests.D. Colombia became more peaceful than Brazil.10. Which is probably a function of Barajas's coffee plantation?A. A method of protecting cattle and wildlife.B. A substitute for hunting of wild animals.C. A barrier between man and wild animals.D. A shelter for cattle against human hunters.11. What does the underlined word "steward" mean in the last paragraph?A. Farmer.B. Master.C. Guardian.D. Explorer.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学年房山中学高三英语期末考试试卷及答案
2019-2020学年房山中学高三英语期末考试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AAshish, the 48-year-old surgeon encourages others to do the same through Bloodline, a nonprofit association he founded in 2017. Besides this, he donates blood regularly.According to Ashish, who has been a doctor at a United Family Healthcare hospital in Shanghai since 2007, Bloodline is aimed at creating a blood bank that can help the community as well as individuals with rare blood types who face an urgent need for blood.“My father, a doctor who specialized in treating chest infections, only charged those who could afford the medical treatment. For those who couldn’t pay, he never mentioned money and instead gave them the drugs for free.” he says.During his growing up years, Ashish was also exposed to social services, helping collect food and money for a local children’s hospital.Ashish first donated blood when he was 18. After arriving in China in 2003, Ashish learned mandarin at Fudan University in Shanghai before becoming a graduate student in general surgery at Shanghai Huashan Hospital. Here, he continued participating in blood donation drives as his way of giving back to society. In 2011, he became a volunteer at the Shanghai Blood Center where he helped raise public awareness about blood donations.The idea of setting up an online community for this cause came in 2013 as he believed that there should be a group of expats who get together voluntarily to work with patients and organize regular gatherings to raise public awareness. In 2017, this community was officially registered as Bloodline.“Our organization currently has a presence in 14 cities, including Beijing, Dalian, and Guangzhou. It’s often a small group of people in each city but they can help a great deal.” says Ashish, who holds the roles of ambassador and director of the foreign volunteers group at the Shanghai Blood Center.Ashish has also emphasize the importance of raising awareness of their causes in children, noting that people from the younger generations are more receptive to the idea of donating blood. Bloodline is currently planning to launch a junior club within the organization where youth will get to tour blood donation centers, witness how the blood is dealt, who the end users are, and the difference that they can make to the lives of those in need of blood.“We come from different countries and have different skin color1 s, but the blood streaming through ourbodies is the same. When there is a need to roll up sleeves and save lives, we will step forward bravely.” he says.1. The goal of Bloodline is to ________.A. set up a blood bank that can help the communityB. raise money for the charityC. assist children in local hospitalsD. help poor people reduce their financial burden2. What can we infer about Ashish through the whole passage? He ________.A. benefited from blood donation himselfB. got his medical degree in FuDan UniversityC. got the idea of founding Bloodline from his fatherD. helped collect food and money for a local children’s hospital3. What message does the passage convey to us?A. Giving is receivingB. Hard work leads to success.C. One needs to return the favor.D. Love is without boundaries.BOnline education has grown fast over the past ten years. The explosion of technology has made teaching outside the traditional classroom possible for teachers and has provided learners with easy access to course materials. Its attractiveness, benefits, and challenges are addressed.In April, 2005, I was approached by a student who was interested in our doctoral program. However, the first question out of her mouth was, “Do you offer any online courses?” Later that day, as I was reading the conference program guide trying for interesting presentations, I noticed many workshops on web-based learning and online education. I later attended two of those workshops and met several professors from different universities who had either taught online courses for quite some time or who were discovering the best practice for teaching online. These experiences helped me realize at least to some extent the degree of growth in online education.My responsibilities for the term included gaining more understanding of online education. Consequently, I made several attempts to enrich my knowledge of distance learning and online teaching. I consulted with my colleagues who were teaching online courses. This helped me recognize the importance of getting materials prepared even before the start of a term. I also learned that online courses may consume more time than regular classroom teaching. And I attended several workshops regarding online education and established a network with those who were involved in online programs at other universities. I will consider these people as my consultants asI begin to design my own online course. Also, I conducted a brief survey with 15 students and two faculty members who had taken or taught an online course before to understand their experience. Eventually I completed a literature review which gave me the foundation and the background of understanding the need for online education.4. What benefits the development of online education?A. Teachers’ good teaching ability.B. Lack of traditional classrooms.C. Learners’ access to free courses.D. The rapid advance of technology.5. Why did the author take a student for example?A. To show students’ love for the doctoral program.B. To persuade learners of traditional education.C. To explain the growing trend of online education.D. To predict the future of the teaching career.6. What caused the author to know more about online education?A. The appetite for knowledge.B. The professional responsibilities.C. The requirement of research.D. The colleagues’ encouragement.7. What is the author’s attitude to online education?A. Carefree.B. Doubtful.C. Supportive.D. Unwilling.CHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising:smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or at least cost-neutral8. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie9. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around10. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards11. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.DThe prevalence of melanoma (黑素瘤) has been rapidly rising around the world for nearly a century. While some of the increase may be due to better detection, researchers also believe it’s because we’re spending more time outdoors in the sun, vacationing to warmer climates during the winter and using tanning beds. That rise is concerning, since melanoma is the most dangerous kind of skin cancer.Most of us know to cover up and apply sunscreen on hot, sunny days, but when fall arrives, we tend to drop those habits. Experts warn that’s a mistake. Though there’s less need for sun protection after summer ends, exposure to UV rays still adds up.What precautions you should take to defend against melanoma during the cooler months depends on where you are in the world. That’s because the further away you are from the equator, the more UV rays weaken in the winter. “In southern England or Canada, the daily dose of UVA on a clear summer day is 6.5 times higher than on a clear winter day,” says Professor Brian Diffey of the British Association of Dermatologists. “People in those countries typically receive only about 5% of their annual UV exposure in the winter months.”But no matter where you are, even during colder, lower risk months, it’s a mistake to put your sun-protection habits on ice. “It’s important to wear sun-screen when there is a lot of glare from the snow,” says Victoria Mar, director of the Victorian Melanoma Service at Alfred Hospital in Melbourne, Australia.Finally, you should monitor your moles(痣). “Early detection of melanoma is vital for successful treatment,” says Diffey. If it’s caught before it spreads to other parts of the body, the patient will have 99 % of chance to survive for five years. If it’s caught late, that can drop to 25%. Warning signs are a mole that’s changing size, shape or colour, or one that’s asymmetrical — sometimes referred to as “ugly duckling” moles. If you have concerns, talk to your doctor.12. What’s the main cause of the rise ofmelanoma?A. The climate change.B. Better detection.C. More exposure to the sun.D. The increase ofskin cancer.13.What’s a mistake according to experts?A. Applying sunscreen in summer.B. Wearing sun-screen when there is snow.C. Using sunscreen during lower risk months.D. Dropping sun-protection habits in winter.14. What can we learn from the last paragraph?A. Prevention is better than cure.B. Health is better than wealth.C. A disease known is half cured.D. When the sun comes in, the doctor comes out.15. What is the best title of the text?A. Detect Melanoma.B. Beware Winter Rays.C. Monitor Your Moles.D. Spend Less Time Outdoors.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。

He was 3 when he started school. He had autism(自闭症)and he didn't speak."Amos struggled to make friends and fit in, but there was always one person there who was very happy to see him. Raymond Brown has worked at the school as a guard for the past 15 years. All of the students know and love him, and he's truly a friend to all. He started callingAdrian's son “Famous Amos” on day one. To the mom's surprise, Amos quickly began responding with a cheerful "Hey, Brown” whenever he saw him. "He wasn't even saying 'daddy' at home, so it was really something, "Adriansaid.“Amos is a hard friend to have,"Adrianexplained, "He takes a lot more than he gives and that's tough for children. But those kids saw that he was popular and loved, and they started fighting over who would get to hold Amos' hand on the way to the classroom. It meant so much to me that he was favored by the other children at school, and Mr. Brown had a big hand in that.”About a year ago, school officials nominated Mr. Brown forNorth Carolina's School Hero, a $20,000 prize. When the results came out and he didn't win,Adrianwas heartbroken. She couldn't let the disappointing results stand, so she took to Facebook and created an annual “Famous Amos” prize for Mr. Brown in their community. Her neighbors answered the call, donating $35,000 in just one week! Townspeople and school officials gathered in March to celebrate Mr. Brown and give him the money they'd raised.

A small donation from the community.BAccording to a survey, the wasteof food on the dining table occupies 10% of the total grain output.Last week, Meituan, a giant online food ordering platform, co-published a proposal with a number of business organizations, calling on restaurants to stop food waste and help develop new eating habits for customers. Following the proposal, merchants are asked to offer guidance for consumers, including reminding them during the ordering process about the taste of the ingredients, portion sizes and other information about the dishes, to helpthem avoid excessive ordering and food waste.Catering（餐饮)associations in more than 18 provinces have also joined the campaign to remove food waste. The Wuhan Catering Association proposed an “NT" ordering code for restaurants in which a group of 10 diners would only order enough for nine people. More food is only brought to the table if required. On Friday, the China Cuisine Association announced that it had teamed up with Ele. me, the Alibaba Group Holding-owned food delivery platform, to launch a "half-dish plan," encouraging restaurants to provide customers with the option to order smaller portions.Tang Zhisong, a professor at Southwest University Education School, said "Evaluating how much you can eat, how much you should buy and how to deal with the leftover is a way for young people to improve their self-management. It's also a means to teach them sharing food, caring about others, and more importantly, developing a mindset of suitability. "4. What's the purpose of the proposal mentioned in the passage?A. To change customers' attitude toward life.B. To promote a new policy on food delivery.C. To spread the idea of healthy eating.D. To encourage restaurants to reduce food waste.5.

First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.Paper is mainly made from cellulose (纤维素)，which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-color1 edstuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systemscan be developed.The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industry to do the same. The world will be a better place for it!12. What can we infer from the text?A. The use of recycled paper will double in 40 years.B. Recycling paper helps relieve global climate change.C. Wastepaper can easily break down in landfills.D. There are not enough landfills for wastepaper.13. What makes recycled paper more acceptable?A. The great demand of trees.B. The low processing cost.C. Its dark-color1 ed feature.D. Its improved print performance.14. What does the author propose?A. Punishing the act of cutting trees.B. Recycling paper.C. Improving recycling system.D. Promoting paper industry.15. How is the text mainly developed?A. By analyzing causes and effects.B. By offering research plans and data.C. By discussing problems and solutions.D. By comparing strengths and weaknesses.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学年房山中学高三英语期末试题及答案
2019-2020学年房山中学高三英语期末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APeople in the Middle Ages did eat with their hands. Personal utensils (餐具) were mostly unheard of, especially forks. There were spoons to help serve, but only special guests would receive a knife from the host. Everyone else would be expected to bring their own. Of course, eating with one's hands can be quite a sticky situation, so towels were provided to help diners stay at least somewhat clean as they ate.Still, dining was often a messy affair. At special occasions in the wealthiest households, women tended to dine alone, separate from the men. Women were expected to uphold a quality of grace. Eating greasy meat by hand would certainly not help! Once the men and women had finished their meals, they would come together to socialize.Dietary scholars of the Middle Ages believed that the foods in a meal needed to be served and eaten in order of heaviness. The lightest and most easily digested foods, such as fruits and cheeses, were eaten first to help the digestive (消化) system get started. Once digestion was underway, greens and light meats, such as lettuce, cabbage and chicken, could be eaten. Last came the heavier vegetables and meats, such as carrots, beans, beef, pork, and mutton. This method was considered the most healthful way to eat.The main and largest meal of the day was supper, and it was eaten at midday. Dinner was a light meal, and many of those in nobility (贵族) -the highest levels of the Middle Ages society-skipped breakfast altogether. Breakfast was considered unnecessary for those who did not perform physical work. Snacks and any other eating during the day were viewed the same way. Commoners, or the working class, were allowed to eat breakfast and small meals throughout the day.1. What did people in the Middle Ages usually do at the dinner table?A. They cleaned hands before meals.B. They used personal utensils.C. They had to use knives at dinner.D. They ate mostly with hands.2. What is the third paragraph mainly about?A. The order of eating foods.B. The weight of various foods.C. The principles of digesting foods.D. The list of healthy foods.3. Why did the nobility avoid eating breakfast?A. Breakfast was wasted for the nobility.B. Breakfast was viewed as unnecessary.C. Breakfast was considered as a light meal.D. Breakfast was saved for commoners.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 raceCSimply being quiet is a growing appeal. Lots of business have appeared to meet a rising demand for quiet time, from silent weekend getaways to silent dining, silent reading parties and even silent dating. Silence can mean different things to different people. We are usually silent only with those closest to us. So there is something almost radical(不同凡响的)about the recent trend towards enjoying silence with strangers.Mariel started a regular silent reading party inDundeejust under a year ago. Readers bring their books and meet in a bar, where they read together in silence for an hour or sometimes two and then put their books away to chat and have a drink. “When the reading party starts, everything goes quiet,” says Mariel, “ It’s a little bit surreal (超现实的), especially in what is usually a noisy bar. However, there is something special about sharing the silence with others. It offers a chance to escape from reality; everyone is so busy with work and with technology being ever present. An event like thisgives people the opportunity to escape these things for a while.”Honi Ryan is an artist based inBerlinwho began hosting silent dinner back in 2006. The rules of the dinner are: no talking, no using your voice, no reading or writing, trying to make as little noise as possible, not connecting with technology, and staying for at least two hours. So far she has taken her silent dinner project toMexico,theUS,AustraliaandChina. “It’s evident that the age-old connections we make over food do not depend on the words around it. Silence creates the space for the people and places involved to fill with whatever is needed;itis quite different from our usual social behaviors.”8. Why have lots of silent businesses appeared?A. To satisfy people’s demand for silence.B. To make people get close to each other.C. To appeal to young people.D. To change people’s old way of life.9. What can we learn about Mariel’s silent reading parties?A. Readers can use their voice while reading.B. Readers can be busy with their work.C. Readers can connect with technology.D. Readers can chat and drink after reading.10. The underlined word “it” in the last paragraph refers to .A. noiseB. spaceC. silenceD. food11. What can be a suitable title for the text?A. Escape from Reality.B. Enjoying Being Quiet.C. Silent Reading Parties.D. Silent Dining Projects.DAustralia’s Great Barrier Reef has lost 50% of its corals (珊瑚) within 30 years, with climate change a key driver of reef disturbance, a new study has found.Researchers from the ARC Centre of Excellence for Coral Reef Studies, inQueensland, northeasternAustralia, studied coral communities and theirsize along the length of theGreat Barrier Reefbetween 1995 and 2017, finding all coral populations disappear gradually, they said.Reefs are important to the health of ocean ecosystems — without them, ecosystems break down and ocean life dies.Coral population decreases happened in both shallow and deep water coral species, experts found, but branching and table-shaped corals — which provide habitats for fish — were worst affected by mass bleaching (漂白) events in 2016.Warm ocean temperatures are the main reason of coral bleaching. Bleaching doesn’t kill coral immediately,but if temperatures remain high, eventually the coral will die, destroying a natural habitat for many species of ocean life.“We used to think the Great Barrier Reef is protected by its huge size — but in fact our results show that even the world’s largest and ly well-protected reef system is increasingly destroyed and in decline,” Terry Hughes, an outstanding professor at the ARC Centre of Excellence for Coral Reef Studies, said.“There is no time to lose — we must sharply decrease greenhouse gas emissions as soon as possible,” the reporter warned in the paper, published in the Proceedings of the Royal Society journal.12. What has mainly influenced the coral populations of theGreat Barrier Reef?A. Destroyed habitats.B. Climate change.C. Lack of seafood.D. Bleaching events.13. What can we learn from the passage?A. Many species has been dying out slowly.B. The size of reefs contributes to their protection.C. Ocean ecosystems don’t develop without reefs.D. Bleaching continually disturbs table-shaped corals.14. What attitude does the reporter hold to the present situation of theGreat Barrier Reef?A. Worried.B. Angry.C. Hopeful.D. Surprised.15. What is probably the best title for the passage?A. Climate change damages theGreat Barrier ReefB. The Species of ocean Life Are In DangerC. Greenhouse Gas Emissions Get WorseD. Sea Ecosystems Are In Decline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学年房山中学高三英语上学期期末考试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AThailand is a country with a long and rich history. It is also one of those countries which have many traditions which modern times fortunately have not affected. Thailand is famous for its unique culture. It is well worth noting that Thai culture hasbeen handed down from one generation to the next.Thai Classical DanceThe inspiring culture includes local music and wonderful Thai dances. The dances of course have something to do with its deep-rooted Buddhist religion, fighting arts and beautiful clothing. Thai classical dance performances are generally performed by gracious (高雅的) Thai ladies wearing beautiful Thai local costumes. Most resort (旅游胜地) areas and many hotels frequently offer these Thai culture dance shows for foreign visitors.Thai GreetingThe unique Thai gesture of greeting another person, the wai, is especiallyone of the great aspects of Thai culture. The wai is when a person joins both hands to either head or chest level while bending their head slightly towards his hands. This way of greeting is especially done when a younger person greets an older person and it indicates a sign of respect to their elders. Employees would also wai their managers even if the manager would be younger than themselves.BangkokBangkok is the culture center of Thailand and has been the Thai capital since the end of the eighteenth century. Observing Thai culture in Bangkok can be great experience as the combination of modern times and traditions have created a kind of unique atmosphere. Bangkok offers a package of Thai culture which is shown by numerous beautiful Buddhist temples and many examples of modern Thai architecture.Bangkok National MuseumAnother location in Bangkok where one can enjoy and see Thai culture is at the famed Bangkok national museum, which offers tourists an opportunity to view national treasures and unique Thai art pieces with its culture feature dating back as early as the late sixteenth century.1.Thai classical dance is related to ________.A.its living level and educationB.its history and architectural styleC.its customsD.its religious belief2.In Thailand a worker uses the gesture, the wai , to greet________.A.his close friend.B.a young stranger.C.his younger colleagues.D.his young boss.3.What make Thai culture in Bangkok so unique?A.The long history and fine weather of Bangkok.B.The mixture of the modern culture and traditions.C.A number of beautiful Thai Buddhist templesD.Many examples of modern Thai architecture.BYou’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source（来源）of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part ofVon Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.In a piece from 2018, Von Wong wanted to illustrate（说明）a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped（倾倒）from a truck all atonce.Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.4. What are Von Wong’s artworks intended for?A. Beautifying the city he lives in.B. Introducing eco-friendly products.C. Drawing public attention to plastic waste.D. Reducing garbage on the beach.5. Why does the author discuss plastic straws in paragraph 3?A. To show the difficulty of their recycling.B. To explain why they are useful.C. To voice his views on modern art.D. To find a substitute for them.6. What effect would “Truckload of Plastic” have on viewers?A. Calming.B. Disturbing.C. Refreshing.D. Challenging.7. Which of the following can be the best title for the text?A. Artists’ Opinions on Plastic SafetyB. Media Interest in Contemporary ArtC. Responsibility Demanded of Big CompaniesD. Ocean Plastics Transformed into SculpturesCImagine the feeling of swinging at a baseball going 100 miles per hour—without leaving your living room, or being in race car as it roars down the track, while you are sitting on the couch.These are just some of the ways that sports business leaders say virtual reality (VR) will revolutionize how people train for and experience sports. Virtual and augmented（增强的）realities are together known as mixed reality (MR). “American footballers are already using VR to better train their minds andread the field,” Ludden said. “This can allow players to perfect their skills without risking injury.”Canadian company D-BOX Technologies designs and produces moving seats found in cinema and theme parks. It is now moving into sports, and shows its Formula One (F1) racing simulator（模拟器）. The seats stimulate the force of gravity, speed and every shaking as Fl champion Lewis Hamilton zips around city streets.A simulation seat uses pre-programed data now. Someday, though, it could use real-time information sent by the car. “They couldbroadcast live content through a network in pop-up theaters around the world,” Ludden said. Say you want to experience the true stress of a batter being up against major-league baseball pitcher. “You can have a heartbeat added to the sensation on the seat and then you can feel it, boom, boom,” Maheu explained. “When he swings and hits the ball, you can have an impact.”One day, fans around the world could physically experience every game from their favorite player in real time. Ludden said that current and near-future technology could create “augmented stadiums” for live audiences.Panasonic launched its “Smart Venue” plans which included the overlaying of graphics, advertisements, player statistics and replays on the field of play at a pro football game. “If you are seated in the cheap seats, you can see this really useful.” “Fans may someday join in stadium wide games, using the field as a virtual gaming platform,” Ludden added.8. What does the underlined phrase “read the field” in paragraph 2 mean?A. Get off the playing field.B. Build up a football court.C. Judge the situation on the field.D. Ask players to play on the spot.9. What does Maheu think audiences can do in the future baseball game?A. Enjoy live content in any theater.B. Program the simulation seats in advance.C. Control the force and speed of the baseball.D. Experience the real time game with the player.10. What does Ludden mainly describe in the last paragraph?A. The origin of VR.B. A future stadium.C. An advertisement platform.D. The expectations of audiences.11. What is the main idea of the text?A. VR can improve players' skills for sports.B. VR increases fans' joy in the baseball game.C. VR can improve sports experience for players and fans.D. VR promises a new future for football players and games.DPaper is one of our oldest, simplest and most important inventions.

B.A traveler's journal.C.A news report.D.A trip guide.BWhen Rich Jean wanted to help his daughter, Abigail, learn to read, he took her to the library near their home in Brooklyn, N. Y. That's where they met Hasina Islam, who Jean says arose her interest in reading and the library.“You see what you started? You see that spark that you put in this child?” Jean told Hasina Islam at aStoryCorpsconversation in 2016. At the time, Abigail was 7 and Islam was 27. Their friendship began when Abigail was 3. Through the years, Islam has offered book suggestions that Abigail has read with great enthusiasm. “What's cool is that Hasina has recommended a lot of books that I, at the time, thought might be a little too advanced for you," Jean told Abigail. “Like Charlie and the Chocolate Factory." Abigail said.Islam's own love of the library was sparked when she was in the third grade. She lived near the main branch of the Queens Public Library in New York City, and she went there to research Henry Hudson, an English explorer, for a school project."The librarian made me feel so special.

In the first two scenes, participants were given a sugary drink uponwaking—first from a normal night’s sleep, and then again after a poor night’s sleep during which they were woken up for five minutes every hour. In the third, their sleep was similarly disrupted, but they were given a strong black coffee 30 minutes before consuming the sugary drink.Blood samples from participants were taken following the sugary drink, which mirrored the calories of a typical breakfast, in each experiment. Results showed that one night of disrupted sleep did not worsen the participants’ blood sugar responses at breakfast when compared to a normal night of sleep. However, strong black coffee consumed before breakfast increased the blood sugar response by around 50 percent.By drinking such kind of drink after breakfast, UK researchers found that our bodies’ ability to break down our food healthily is completely improved. Examining the effects of broken sleep and morning coffee across a range of different metabolic markers, scientists at the University of Bath found that, while one night of poor sleep had a limited effect on metabolism, drinking coffee before breakfast could have a negative effect on blood sugar control.“We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee—the more tired we feel, the stronger the coffee is. This simple study is important and has far-reaching health influences, and it indeed moves some coffee drinkers’ heartstrings. As up to now we have had limited knowledge about what this is doing to our bodies, in particular for our metabolic and blood sugar control, so we have a long way to go.” said Professor James Betts, co-director of the Centre for Nutrition, Exercise and Metabolism at the University of Bath.8. How did UK researchers get the result of the experiment?A. By making comparisons.B. By consulting journals.C. By questionnaire.D. By assumption.9. What can we learn from the experiment?A. One night of poor sleep surely affects blood sugar.B. Drinking coffee after breakfast does harm to health.C. Having strong drinks has a good effect on metabolism.D. Drinking coffee at different time has different effects on health.10. What does James Betts think of the study?A. It makes no sense.B. It remains to be continued.C. It is limited and blind.D. It is particular and explicit.11. What can be the best title for the text?A. How Much Coffee to Drink MattersB. Does Coffee Really Wake Up an Appetite?C. How Does Drinking Coffee Affect One’s Sleep?D. Drinking Coffee before Breakfast Harms MetabolismDNextdoor，an online social network for neighbors，says it has attracted $60 million from early backers of technology giants，Google，Amazon and Facebook.The new investment，1ed by venture firm Kleiner Perkins Caufield & Byers and investment firm Tiger Global Management，values Nextdoor at more than $500 million，said a personfamiliar with the matter.Nextdoor members make Facebook-style postings，giving or seeking recommendations for services such as babysitters and yard maintenance or local retailers and restaurants.

2019-2020学年北京市房山区官道中学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.B“Your mind is a garden; your thoughts are the seeds. The harvest can either be flowers or weeds,” William Wordsworth wrote. In the above quote, William suggests that the process of gardening mirrors human life. Depending on what we “plant” in our lives, we bloom (生长茂盛) or don’t. Before you start to work in your garden, it’s necessary to have a vision for it. Thinking of what youwant to grow in your garden and how to lay it out is a good first step in making your vision a fruitful reality. In life, you should consider what you want to create and what you want to achieve, because your mind-garden is like the white paper and the possibilities are endless. Regardless of what you choose to plant, poor soil isn’t suitable for growth. This is why gardeners take the time and energy to upgrade the soil before planting. So, creating the right soil is important to the realization of your goals and dreams. Fortunately, there are countless ways to make your personal bedrock better. Getting an education is one of the most effective ways, which can help you enrich your life’s soil.You don’t have to be an enthusiastic gardener to understand the meaning of “You reap(收获) what you sow.” When a gardener wants tomatoes, they just need to plant tomato seeds. It’s a very clear act that produces an expected result. Each of us has the power to decide which “life seeds” to plant. For example, if you plant ill seeds, it's likely that you’ll experience pain in return. Contrarily, if you plant seeds of kindness and understanding, your life will bloom with happiness and love.A gardener’s trulyarduouswork begins after the seeds are in the ground because a garden requires a lot of care and attention. Regular watering and weeding are required for a healthy garden. So, to ensure your dreams take root, you should be devoted, aware, and present. After countless hours and energy spent, the crops have grown well and are finally ready to be harvested.4. What is important before gardeners break ground in their gardens?A. Receiving some training in planting.B. Drawing up a good plan for their gardens.C. Having the courage to accept the worst outcome.D. Doing research on the common local garden plants.5. What is compared to getting education by the author?A. Improving the condition of the soil.B. Growing your most favorable plants.C. Taking care of the plants in your garden.D. Selecting proper goals in gardening work.6. What does the author want to express in Paragraph 3?A. Your quality of life depends on your positive action.B. Your experience can help you understand plants better.C. Your choice of soil is an important part in your gardening.D. Your knowledge of planting will make you a successful gardener.7. What does the underlined word “arduous” in Paragraph 4 probably mean?A. BeneficialB. CreativeC. Boring.D. ToughCWho is a genius? This question has greatly interested humankind for centuries.Let's state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It's said that history is written by the victors, and those victors set the standards for admission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color1 or belief—they were unacknowledged and rejected by others.A study recently published bySciencefound that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn't take a genius to know the answer: ly not.Here's the good news. In a wired world with constant global communication, we're all positioned to see flashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”8. Whatdoes the author think of victors' standards for joining the genius club?A. They're unfair.B. They're conservative.C. They're objective.D. They're strict.9. What can we infer about girls from the study inScience?A. They think themselves smart.B. They look up to great thinkers.C. They see gender differences earlier than boys.D. They are likely to be influenced by social beliefs10. Why are more geniuses known to the public?A. Improved global communication.B. Less discrimination against women.C.Acceptance of victors' concepts.D. Changes in people's social positions.11. What is the best title for the text?A. Geniuses Think AlikeB. Genius Takes Many FormsC. Genius and IntelligenceD. Genius and LuckDEveryone can be angry. But if you take the time to actually examine your anger instead of just “feeling” angry, you’ll have a better understanding of yourself. Knowing why you feel so angry can provide you with some surprising answers. These answers can enable you to suddenly grow spiritually and mentally.I can give you a personal example. I went to a meeting once and I was verbally attacked over an application I supported at my workplace. Various people went on and on about how terrible this system was and that it never worked. That didn’t bother me that much. I was used to that but one of the comments that was said was, “Your job is pointless.” This really upset meand at the time, I was ly furious(发怒地) with that comment.I was so angry and upset that they would treat me that way. Once I took the time to think about what was really making me so mad. I learned a lot. I realized that the comment was more truethan I wanted to admit. In the big scheme of things, my job was pointless. It wasn’t what I really wanted to be doing with my life and this was what frustrated me the most. Here I was pouring part of my heart and soul into a job I didn’t even really want to do. I was using it as a crutch(拐杖) because I didn’t have the confidence in myself to take the scary road towards what I really wanted to do. As soon as I realized that, a lot of my anger just melted away. I also realized that I needed to start focusing on what I really wanted to do.I now consider this incident as a great gift It got me back on track to moving in the direction I wanted to go with my life. I probably wouldn’t be where I am today if I hadn’t taken the time to figure out why I was really soangry.12. What made the author angry at the meeting?A. The system of the company was terrible.B. Someone said his job is insignificant.C. The policy of the company didn’t work.D. The application he supported was of no effect.13. What brought down the anger of the author?A. The apology someone made at the meeting.B. The crutch he used to take the scary road.C. His awareness of the fact that the comment was true.D. The courage he had to overcome the challenges.14. Why did the author consider the incident as a gift?A. It brought him back on track to the goal.B. It helped him get promoted to a higher position.C. It helped him change his character since then.D. It provided him with confidence in his career.15. What can be the best title of the passage?A. How to Cope with Verbal Attack in a CompanyB. Avoid Being Pointless at WorkC. Anger Is Harmful to HealthD. Understanding Yourself Better Through Anger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学年北京市房山区长阳中学高三英语上学期期末考试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AA brother and a sister have been reunited (重逢) after more than 60 years, thanks to a letter in the Welwynand Hatfield Times. For years John Hannant kept a photo of his long-lost sister, hoping they would meet again.Margery, the eldest of three children, had signed up with the Royal Air Force as part of the war effort, when John was still a baby.The family lost touch and as many years passed only a single letter gave a clue to her whereabouts (下落). The clue was enough for a WHT reader to recognize Margery and put the family back in touch.John, 67, said he had been searching for a long time and a friend suggested writing to the paper.“That’s the one that made it, the letter to the paper,” he said. “It’s like a dream that comes true. The last time we ever heard from Margery was in 1953 after the terrible floods. She wrote home to know if we were all right.My sister Dorothy wrote back, but Margery had moved again and never got the letter.”Having retired from his job as a gardener at Park House, Mr Hannant decided to take action.He and his wife Doreen traveled to Margery’s home in Chelwood Avenue, Hatfield, which she shares with her husband Jack Cooke.Now 88, Margery was recovering from her heart operation, but immediately recognized her brother. John said, “It’s something I never thought that was going to happen but I always hoped it would.” AS well as finding his sister, John has also discovered he now has a nephew, a niece and six grandnieces and grandnephews.1.The headline of the news would be “________”.A.An unforgettable and moving experienceB.The Hannant family lost touch because of warC.A brother and a sister reunited after 60 yearsD.The importance of a letter to WHT2.Margery left her family because ________.A.she attended the air schoolB.she joined the Royal Air ForceC.she had to feed her familyD.a big flood hit her hometown3.Who helped the family reunite after many years?A.Margery’s husband Jack CookeB.The photographer of the photo of Margery.C.A neighbour of Mr Hannant.D.A reader of WHT.BHaley Curfman, 25, of Blackwell, Oklahoma, is a teacher at Blackwell Public School and last yearshe bought a plain(朴素的) white dress, which she set up a station in her classroom for her students to decorate, encouraging them to go and draw on the dress whenever they had free time. Haley set up a station at a table with the dress and some color1 ed markers so that her students could draw on it, having first seen the idea on Pinterest.After the kids had finished the design, she then surprised them all by wearing the dress to class, sharing pictures of herself in it on Facebook in a post that has since been shared over 200, 000 times.For teachers looking to do something similar for their own students, Haley said that she bought the dress off Amazon for less than $ 20 about six months ago and pre-washed the dress before she started the project. She used markers from Walmart. But she said these things can be bought in other places. She said, “To do the project, I set up a station at a table with the dress and markers. It takes anywhere from two weeks to a month to complete as we just work on it here and there when time allows. You'd better give the students enough time so they don't have to hurry.”“Teachers have been sharing their dresses, T-shirts, etc. with me that they've been creating since the 1950s with the same idea. It is amazing, and I love the fact that you are sharing them with me! Thank you all so much for your kindness and support,” she wrote on Facebook.Asked why she came up with the idea, Haley told Scary Mommy. “We don't have art in our school, so, I always try to do little creative projects when possible.”4. What did Haley use the plain white dress to do?A. To teach her students painting.B. To prepare for her presentation.C. To ask her students to draw on it.D. To help her students with their homework.5. What do we know about the finished dress?A. It took Haley by surprise.B. It is kept by Haley at home.C. It is the product of a new idea.D. It has enjoyed popularity online.6. What should a teacher do if he or she wants to follow Haley's example?A. Buy the same dress online.B. Give the kids enough time.C. Buy the same markers in Walmart.D. Leave the finished work untouched.7. Why did Haley carry out the project?A. To teach art to her students.B. To show her idea on Pinterest.C. To share it with other teachers.D. To exciteher students' creativity.CChina's Mars probe Tianwen-1 successfully landed on the surface of the red planet on May 15, 2021, leaving a Chinese footprint on Mars for the first time and in its first attempt, becoming the only other nation besides theUSto get such an achievement. The Tianwen-1 probe touched down at its pre-selected landing area in the southern part of Utopia Planitia, a wide plain on Mars, at 7:18 a.m.(Beijing Time), after three months scanning the whole planet on Mars docking orbit, the China National Space Administration(CNSA) announced.Tianwen-1, including an orbiter, a lander and a rover, was launched from the 'Wenchang Spacecraft Launch Site on the coast of southernChinas islandprovinceofHainanon July 23, 2020. It was the first step inChina's planetary exploration of the solar system, with the aim of completing orbiting, landing and roving on the red planet in one mission. According to the administration, the country's first Martian probe will conduct scientific investigations about the Martian soil, environment, atmosphere as well as water.China's planetary exploration program has been named “Tianwen”, which was named after a long poem by the famous ancient poet Qu Yuan. The name represents the Chinese nation's willpower in pursuing truth, the country's cultural inheritance of its understanding of nature and universe, as well as the unending exploration in science and technology.China's first Mars rover has been named “Zhurong”, which means the god of fire in an ancient Chinese story. The name indicates Chinese people's blessing for the rover to light the flame ofChina's planetary exploration. The rover has six wheels and four solar panels, and carries 13 scientific instruments. According to the CNSA, Zhurong has started its scientific exploration after moving from the landing platform onto the Red Planet's surface on May 22.More than 40 Mars missions have been launched since the 1960s, but only about half have succeeded. It is the first time in the world that orbiting, landing and roving on Mars has been completed in one launch mission,andChinahas come to the forefront of Mars exploration in the world.8. What can we learn from the first two paragraphs?A. China is the only nation to launch a probe to Mars.B. Tianwen-1 landed in the northern part of the planet.C. Tianwen-1 scanned the southern part of the planet.D. The Mars probe will carry out scientific investigations.9. How did the planetary exploration program get its name?A. From a long poem by Qu Yuan.B. From an ancient Chinese story.C. From Chinese nation's willpower.D. From theChinaNational Space Administration.10. Why does the author sayChinahas come to the leading position of Mars exploration?A. The rover carried many scientific instruments.B. China completed three tasks in one attempt.C. The rover successfully moved from the landing platform onto Mars.D. The CNSA is continuously exploring science and technology.11. What is the text mainly about?A. Tianwen-1 completed its mission.B. Tianwen-1 represented the god of fire.C. Tianwen-1 successfully landed on Mars.D. Tianwen-1 was launched from Wenchang.DSome years ago a young man applied to a large United States optical firm for a job as a lens designer. He apologized for lack of training, but on announcing that he owned two copies of the classic Conrady's Applied Optics and Optical Design, one for his office and a second for his bedside table, he was hired on the spot. Perhaps the story will be repeated some day with Buchdahl's Introduction to Hamiltonian Optics as a similar certificate of qualification.Hamiltonian theory describes with powerful generality the overall properties of optical systems considered as ‘black boxes’, although it does not describe the detailed structure needed to construct the systems and achieve these properties. Buchdahl's book is therefore on the subject of geometrical optics, but it is not about how to design lenses. It is, however a compact comprehensive account of the fundamentals of the theory written with the lens designer's needs very much in mind. Every lens designer worth his salt has at some time in his careerattempted to apply the broad concepts of Hamiltonian optics to the solutions of practical problems. Success has been sufficiently rare that the theory, as such, has made little direct contribution to techniques for optical instrument design. The failures have been frustrating because of the obvious fundamental power of the theory and because of its conceptual elegance. The indirect effects have been large, however, both in contributing to an understanding of fundamental principles that govern the overall behavior of optical systems and in pointing the way to other, more practical, theoretical approaches.Buchdahl approaches the subject not only as a capable mathematical physicist, but as one who with a knowledge of practical optics has made a significant contribution to geometrical optical theory. Buchdahl's approach has, over the last decade, had a major impact on modern lens design with computers. Thus, he brings to this exposition of Hamiltonian optics a familiarity with practical optics not usually found in authors on this subject.The author claims his book to be non-mathematical, and indeed it might be so viewed by a professional mathematician. From the point of view of many physicists and engineers, it will appear to be quite mathematical. Moreover, this is a tightly written book. The subject matter is developed with precision, and the author expects the reader, at very point, to be master of the preceding exposition.12. Hamiltonian theory met with failures as a result of ______.A. newer finding related to the wave particle nature of lightB. very complicated concepts too difficult to understand by most lens designersC. too much mathematical detail in the theoryD. not enough practical information offered by the theory to allow for use by lens crafters13. The author of this passage implies that Introduction to Hamiltonian Optics is necessary to ______.A. the students who are major in mathematical geometryB. those who want to grasp the basic principles of optical systemsC. the lens designers who look for instructions on practical designsD. those who are interested in physics14. The article points out that the great benefits of Hamiltonian optics have been found is ______.A. indirect ways of learning mathematicsB. a fundamental power within the theoryC. the conceptual elegance of the theoryD. the practical applications of the theory in finding new approaches to old problems15. This passage is probably excerpted from ______.A. a review of a bookB. a chemistry textbookC. an optician's essayD. a general science text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。
