What’s more, they discovered that a husband’s social class, based on his occupation, had a greater influence on his wife’s longevity(长寿) than her own class.“Women traditionally take more responsibility for the home than men do, and, as a result, women’s levels of education might be more important for determining lifestyles－for example, in terms of food choices－than those of men,” say Srs. Robert Erikson and Jenny Torssander of the Swedish Institute for Social Research inStockholm.The results show that a husband’s level of education does not influence his longevity, but that men with partners who had quit studying after school were 25 per cent more likely to die early than men living with women holding university degrees. In turn, those married to women with university degrees were 13 percent more likely to die early than those whose wives had post-graduate qualifications.According to the researchers, a woman with a good education may not marry a man who drinks and smokes too much or who drives carelessly, and men with such habits may not prefer highly educated woman. Drs. Erikson and Torssander also suggest that better-educated women may be more aware of what healthy eating and good health care consist of.The findings suggest that education has a huge impact on how long and how well people live. It also reflects social factors, since educated individuals usually have better jobs, which allow them to afford healthier diets and lifestyles, as well as better health care.4. In this passage the author intends to ________.A. present the results of a studyB. encourage women to get higher educationC. analyze the relationship between education and lifeD. discuss why women usually live longer than men5. A woman with higher education is likely to ________.A. teach her children wellB. earn more money than her husbandC. marry a man without many bad habitsD. choose a husband with a higher degree than hers6. A wife’s education has more effect on a family than a husband’s because ________.A. women make more sacrifices to their families than men doB. most women have higher degrees than their husbandsC. most men marry women with higher degreesD. women have a leading role in the home life of most families7. We learn from the passage that ________.A. a man with a lot of education lives longer than one with littleB. educated wives tend to choose healthy lifestyles for their familiesC. highly-educated women don’t marry uneducated menD. a man’s longevity depends on not only his wife’s level of education but also his ownCIt was once considered an important status symbol ---but having a home phone is increasingly seen asa white elephant. New figures show that one in five households no longer bother with a landline（固定电话），and almost a third of those that do never actually use it.The vast majority of people who still have a home phone ——72 percent ——say they only have it because it is part of their broadband package.But that's not the only reason to desert the home phone - 20 percent of those surveyed said that they were fed up with the number of cold calls and would-be scammers（诈骗者）.Digital media expert Dr. Elinor Carmi said there was a generational and social divide in phone use. She explained："If you,re young and have the mobility to go outside, you would rely on a mobile phone. But if you are older, disabled and perhaps poorer, our research shows you're more likely to use a landline. If you are richer, you will have access to more smart devices --- a smart TV, smartphone or laptop. But the poorer you are --- or if you are older, your use of these devices is more limited.”Last year, research from regulator Ofcom found that the amount of time spent on landline calls annually in theUKhad halved over just six years, to 54 billion minutes. The new study also showed that more than a quarter of households have decided to find a broadband provider that does not charge for their unused landline, but only six percent have done so.8. The underlined part “ a white elephant" in Paragraph 1 probably refers to something that isA. costly but effectiveB. useful and beautifulC. expensive but uselessD. cheap and necessary9. What's the main reason why some people still have a home phone?A. Their broadband package contains it.B. Their family can only afford to use it.C. They are used to using a home phone.D. They consider it an important status symbol.10. Which of the following is more likely to use a landline?A. A young adventurer.B. An old poor gardener.C. An outdoor photographer.D. A famous indoor designer.11. What's the best title of the text?A. End of the landline?B. Fed up with cold calls?C. The history of phonesD. Different choices of phonesDLast summer, Maria and her mother moved from their house in the countryside to a flat building in Chicago. Maria really liked some things about the city, but she missed her house and yard in the countryside.One day, Maria was in her flat building when she noticed her neighbor, Mrs. Garcia, carrying a gardening tool and a bag of soil. Maria wondered how Mrs. Garcia was able to garden in the city.“My mom used to grow the most delicious vegetables, and I know she misses her garden now that we don’t have a yard,” said Maria.Mrs. Garcia laughed. “I’ll show you,” she said.Maria thought that Mrs. Garcia would take her to the park, but she took her to the roof. When the door opened, Maria was surprised to see rows of flowers and vegetables on the roof.“What a wonderful garden!” said Maria.Mrs. Garcia told Maria that for a long time the roof was just an empty space. Then some of the people in thebuilding asked the owners to turn it into a community garden. The building owners liked the idea because the plants not only helped to keep the air clean, but they also helped to keep the building cooler during warmer weather.“I plant flowers in my own place,” Mrs. Garcia said, “but you would be surprised by how different the plants are up here. Some people grow vegetables just like your mom. You can do some of the same things in the city as in the countryside. You just have to be creative!”12. Where did Mrs. Garcia take Maria to one day?A. The park.B. The roof.C. The garden in front of her house.D. The countryside.13. Which of the following is NOT the good side of the community garden?A. It made the building stronger.B.

2019-2020学年合肥市第一中学高三英语下学期期末考试试卷及答案
2019-2020学年合肥市第一中学高三英语下学期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ALast summer, Katie Steller pulled off the freeway on her way to work inMinneapolis. She stopped at a traffic light, where a man was sitting with a sign asking for help. She rolled down her window and shouted. “Hey. I’m driving around giving free haircuts. Do you want one right now?” The man laughed, then paused. “Actually,” he said, “I was really hoping to get a haircut.” Steller pulled out a red chair from her car and helped the man cut his hair immediately. After the work was done, the man looked in a mirror. “I look good!” he said.Up to now, Steller has given 30 or so such haircuts around the city to people with little influence, and she is strongly aware of the power of her cleanup job.As a teen, she suffered from a severe disease, causing her hair to get thinned, so her mother arranged for Steller’s first professional haircut. “To sit down and have somebody look at me and talk to me like a person and not just an illness, it helped me feel cared about and less alone,” she says. After that, Steller knew she wanted to have her own barbershop so she could help people feel the way she’d felt that day. Not long after finishing cosmetology (美容术) school in 2009, she began what she now calls her Red Chair Project, reaching out to people on the streets. Her aim was that by doing some kind acts, others would be inspired to spread their own.“Part of what broke my heart was just how lonely peoplelooked,” she said. “I thought maybe I’d go around and ask if people want free haircuts. I can’t fix their problems, but maybe I can help them feel less alone for a moment.”It all began with a belief in simple acts of kindness, such as a free haircut. “The way you show up in the world matters,” said Steller. “You have no idea what people are going to do with the kindness that you give them.”1. How does the writer begin the passage?A. By making a comparison.B. By giving a reason.C. By raising a question.D. By describing a scene.2. What made Stellar start the Red Chair Project?A. Her mother’s love for her.B. Her interest in cosmetology.C. Her care for those in need.D. Her wish to fight severe diseases.3. What did Stellar expect from the project?A. To spread kindness.B. To solve social problems.C. To deal with relationships.D. To make people look smarter.BAt any moment, about half the world’s population is wearing denim（牛仔布）clothes. But few realize tiny bits of denim have been adding up to a surprising amount of pollution in water, as a new study shows.Sam Athey, one of the study’s authors, says, “Even though denim is made of a natural material—cotton, it contains chemicals.” Cotton fibers were treated with many types of chemicals, she notes. Some improve its durability and feel. Others give denim its distinctive blue color1 .Athey and her team washed jeans and found that about 50,000 microfibers came off from each pair per wash. Not all of those fibers make their way into the environment. Wastewater treatment plants catch about 83 to 99 percent ofthem. Catching 99 percent may sound pretty good. But one percent of 50,000 is still 500 fibers per wash. And since every pair of jeans is washed again and again, it still adds up to lots of microfibers entering the water environment.Denim microfibers showed up in sediment（沉淀物）from the Great Lakes. More of these fibers polluted a series of shallow lakesin southern Ontario. They even turned up in sediment from the Arctic Ocean in northern Canada. The team found denim accounted for 12 to 23 percent of microfibers in the sediment. There were other microfibers too. But the team focused on denim because so many people wear jeans.“Everyone wears jeans so they could be our largest input of microfibers into our streams and soils,” Athey says. “An easy way to limit that is by washing our jeans less often.” Athey grew up thinking she should wash her jeans after wearing them every couple of times, but most jean companies recommend washing them no more than once a month. “The solution is not that you shouldn’t wear jeans,” she says. “We need to buy fewer denim clothes and only wash them when they truly need it.”4. Which of the following is TRUE according to the passage?A. Chemicals are contained in natural cotton.B. Chemicals can make denim color1 ful.C. Chemicals prevent fibers from falling.D. Chemicals can make the life of denim longer.5. What does the underlined word “them” in Paragraph 3 refer to?A. Denim.B. Sediment.C. Microfibers.D. Chemicals.6. What does the author mainly want to tell us through Athey’s words ?A. To avoid wearing jeans.B. To reduce denim consumption.C. To wash jeans more often.D. To limit input in denim production.7. In which section of a magazine might the text be found?A. Science.B. Entertainment.C. Tourism.D. Geography.CDid you know people who live in different parts ofChinahave different habits and preferences? For example, people from southernChinaprefer to eat vegetables, while people from northChinalike to eat meat. According to a new study in a journal, gene variations (变异) might be responsible for these differences. Researchers fromChina’s BGI collected genetic information from 141,431 Chinese women, who came from 31 provinces and consisted of 36 ethnic minority groups.They found that natural selection has played an important role in the ways that people living in different regions of China have developed, affecting their food preferences, immunities (免疫力) to illness and physical features.A variation of the gene FADS2 is more commonly found in northern people. It helps people metabolize (新陈代谢) fatty acids, which suggests a diet that is rich in flesh. This is due to climate differences.Northern Chinais at a higher latitude. This weather is difficult to grow vegetables in. Therefore, northerners tend to eat more meat.The study also found differences in the immune systems of both groups. Most people in southernChinacarry the gene CR1, which protects against malaria. Malaria was once quite common in southernChina. In order to survive, the genes of people in the south evolved to fight against this disease. However, people in the south are also more sensitive to certain illnesses, as they lack the genes to stop them.Genes can also cause physical differences between northerners and southerners. Most northerners have the ABCC11 gene, which causes dry earwax, less body smell and fewer sweats. These physical differences are also more beneficial to living in cold environments. Southerners are less likely to have this gene, as it did not develop in their population.8. What did the new study focus on?A. Regions.B. Eating habits.C. Gene variations.D. Ethnic minority groups.9. What is the main function of the gene FADS2?A. It helps store fat.B. It helps digest meat.C. It helps gain weight.D. It helps treat an illness.10. According to the study, most northerners ________.A. sweat less frequentlyB. are immune to malariaC. prefer vegetables to meatD. are more sensitive to climates11. How many differences did the study find related to genes?A. Two.B. Three.C. Four.D. Five.DAn unmanned Chinese spacecraft left the earth on a trip to the planet Mars on Thursday. The launch（发射）marks the start of one of China's most important space explorations. China's national space agency launched the spacecraft called Tianwen-1 fromthe Wenchang Spacecraft Launch Center on Hainan Island.The name Tianwen means “Questions to Heaven” in Chinese. The spacecraft took off on China's largest carrier rocket, the Long March 5, and about 36 minutes later, the spacecraft, including an orbiter（轨道飞行器）and a rover（漫游车），was sent into the Earth-Mars orbit. It is expected to reach the orbit of the red planet next February. Tianwen-1 will finish three scientific goals—orbiting the red planet, landing on the Mars and sending a rover to the landing site.Tianwen-1 carries several scientific instruments to observe the planet's atmosphere and surface. It will do a series of scientific researches on the planet's soil, geological structure, environment, atmosphere and water. Besides its daily work of exploring the surface of Mars for 90 days, it will also report back to the earth about its experiences on the red planet, which is millions of miles away. According to experts, discovering signs of life will be its first and most important scientific goal.Tianwen-1's successful landing will make China the second nation to place a spacecraft on Mars. The United States has landed eight vehicles on Mars since 1976. China will be the first to successfully orbit, land and place a vehicle in the same mission. This is China's first independent mission to Mars. The task in 2011 failed when a Russian rocket carrying a Chinese orbiter had problems after launch, and was unable to escape the Earth orbit. Last year, China's Chang e-4 spacecraft became the first to make a landing on the far side of the moon.12. When will Tianwen-1 enter the orbit of Mars?A. 36 minutes later.B. Next Thursday.C. In 90 days.D. Next February.13. What is the main task of Tianwen-1 according to experts?A. Orbiting the Mars.B. Landing on the Mars.C. Discovering signs of life.D. Sending a rover to the landing site.14. Which of the following statements is mentioned in the text?A. Tianwen-1 is the second vehicle landed on the Mars.B. The United States is the first to land vehicles on the Mars.C. Russia helped China place Tianwen-1 on the Mars.D. Chang，e-4 was the first to make a landing on the moon.15. Where can you find this article?A. In a newspaper.B. In a diary.C. In a sci-fi novel.D. In a guide book.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。

Make sure you do it.★Try at least one kind of team sportsBeing a good team player is an important skill in life. You can’t just think of yourself, but have to work well with other people. Other advantages of team sports like basketball, football and baseball are that they keep you fit and healthy, and they are also great fun. Teams usually have a good social life too—you’ll go to lots of parties and make many friends.★Collect somethingOne of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you could collect things that make you remember what you have done, like cinema tickets for films you have seen or letters from friends. The best way to collect is to have a special album to put your collection in and to write what each thing means to you. That way you won’t forget.1. The most important reason for learning to swim is that ________.A. you might feel wellB. it can make you healthyC. you might easily do lots of thingsD. it can save your life2. The writer tells us that one of the best hobbies is to ________ .A. collect somethingB. do some water sportsC. send letters to your friendsD. play basketball with your friends23. The passage is mainly about ________before you are 18.A. good habits to keepB. skills to haveC. things to doD. sports to playBA new study suggests drinking coffee as soon as someone wakes up from a poor night’s sleep greatly affects metabolism(新陈代谢) and blood sugar control.In the study, published in theBritish Journal of Nutrition, UK researchers let 29 healthy men and women take part in three different overnight experiments. 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.4. How did UK researchers get the result of the experiment?A. By making comparisons.B. By consulting journals.C. By questionnaire.D. By assumption.5. 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.6. 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.7. 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 MetabolismCWho 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 LuckDIt is a question people have been asking for ages. Is there a way to turn back the aging process?For centuries, people have been looking for a “fountain of youth”. The idea is that if you find a magical fountain, and drink from its waters, you will not age.Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus (下丘脑). The hypothalamus is part of your brain. It controls important activities within the body.Researchers at New York’s Albert Einstein College of Medicine found that hypothalamus neural (神经的) stem cells also influence how fast aging takes place in the body.What are stem cells(干细胞)? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged tissues and organs.Dongsheng Cai is a professor at the Albert Einstein College of Medicine. He was the lead researcher in a study on aging in mice. He and his team reported their findings in the journal Nature, Cai explained when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost. it eventually leads to aging.Using this information, the researchers began trying to activate, or energize, the hypothalamus laboratory mice. They did this by injecting the animals with stem cells, Later, the researchers examined tissues and tested for changes in behavior. They looked for changes in the strength and coordination (协调) of the animals muscles. Theyalso studied the social behavior and cognitive ability of the mice. The researchers say the results show that the treatment slowed aging in the animals, Cai says injecting middle-aged mice with stem cells from younger mice helped the older animals live longer.But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in.12.

Once in space, it can perform for a few months or up to several years, communicating information that could help find the signs of earthquakes.There are 80 similar satellite projects worldwide, but this is the first high-school based program of its kind in Canada. 30 Manitoba high school students are having a hand in designing and building the satellite, in cooperation with aerospace (航空航天的) experts and 10 students from the University of Manitoba, and with support from two other organizations.The Win-Cube project is not something that goes on a piece of paper; it is real-world engineering, allowing high school students to have an opportunity to learn more about the exciting world of engineering through their participation in this challenging program. It is also taken as a wonderful example of the unique partnerships within Manitoba. Designing, building and launching a satellite with high-school participation will bring this world-class educational project into reality and Manitoba closer to space“These Manitoba high school students deserve congratulations for their enthusiasm, innovation (创新), and a strong love for discovery,” said Education, Citizenship and Youth Minister Peter Bjomson. “We want to make science more relevant, interesting and attractive to high school students by showing them how classroom studies can relate to practical experience in the workplace or, in this case, in space,” Bjomson added.The Win-Cube program is mainly aimed at inspiring a strong desire for discovery on the part of the students. It also shows Manitoba’s devotion to research and innovation and the development of a skilled workforce—all important drivers of knowledge-based economic growth.4. What can we learn from Mr. Bjomson? .A. Those Manitoba high school students are worth praising.B. The study of space can be practically made in classrooms.C. Manitoba high schools are famous for the study of space.D. Scientific research is too far away from high school students.5. What is the primary purpose of the project ? .A. To find the early signs of earthquakes.B. To relate studies to practical.C. To help high school students study real-world engineering.D. To inspire a strong desire for discovery among the students.6. According to the passage, what can we know about the Win-Cube satellite? .A. It is named after Manitoba and its shape.B. It is intended for international communication.C. It is designed like a Rubik’s cube both in shape and size.D. It is challenged by university students around the world.7. What may be the best title for the passage?A. Manitoba SchoolB. Win-Cube ProgramC. Space Co-operationD. Satellite LaunchingC“Heavy hearts, like heavy clouds in the sky, are best relieved by the letting of a little water, the French writer Antoine de Rivarol wrote. This love letter to the cleansing beauty of a good cry is a comforting thought at atime when the continuing stress of the COVID-19 has added heaviness to each of our lives.Scientifically, de Rivarol's poetic image doesn't, if you'll forgive the words used in the poem, hold water. There's limited research on crying, partly because of the difficulty of copying the behavior of real crying in a lab. But even within the previous studies, there's little evidence to suggest that crying provides a physiological cleansing of poisons in people's body.Psychologists believe the relief of a good cry connects with a different emotional process. “It seems that crying occurs just after the peak of the emotional experience, and crying is associated with this return to homeostasis: the process of maintaining a stable psychological state,” said Lauren Bylsma. He also said holding back tears can have negative physical consequences, including headaches and muscle tension. Such restriction can also limit our experiences of joy, gratitude and other positive emotions if we avoid acknowledging our feelings.For me crying has been easier said than done during the COVID-19. Psychologists say it's normal to feel stopped up by the stresses of the past year. We should find opportunities to release and process our emotions.Watching a tear-jerking movie, having an emotional conversation with a close friend, and writing in a journal are healthy ways toelicita cry. Physical activity like light-footed walking or even dancing can also signal our bodies to release some emotional tightness. We can then open up to the flow of feelings that leave us feeling lighter andrefreshed—like a clear sky after a soaking rain.8. What is the weakness of the studies ever clone on crying?A. They were clone in a laboratory setting.B. They cared little about different forms of crying.C. They were always concentrated on people's daily life.D. They showed little about the positive physical effect of crying.9. What is the function of crying according to Lauren Bylsma?A. Curing people of their diseases.B. Keeping emotionally balanced.C. Producing negative mental results.D. Expanding people's experience of joy.10. What does the underlined word “elicit” in the last paragraph mean?A. Produce.B. Postpone.C. Control.D. Repeat.11. What are people advised to do according to the text?A. Learn to hold back their tears wisely.B. Share their emotion with their colleagues.C. Have a good cry when necessary.D. Try to avoid admitting our feelings.DSlowing down was the last thing on Elaine Schaefer's mind when she turned 70 last year. She'd enjoyed an ambitious travel schedule for the previous decade. She didn't feel too old to travel.Yet many people are asking that slightly embarrassing question: Can you be too old to travel? The travel industry has already responded. Try renting a car inEurope, for example. InCroatia, Schaefer wouldn't be able to this year, because the maximum age is 70. Insurance companies require higher rates; tour operators limit certain activities. That feels like a " no" for many travelers.Definitely some folks should think twice before traveling, but not only based on their age. It's their level of fitness, says Kirsten Veldman, a former tour guide who now edits a retirement blog. She recalls a 93-year-old who was disabled and traveling alone on aCaribbeantour. "You can't expect to ask a tour leader to be there for you 24/7 for medical care. " she says. "Tour guides don't have the time, skills, and knowledge for it. So, in this case, my advice is: he shouldn't have traveled with us in this situation. "But some tour operators serve older travelers. For example, Grand Circle Travel started in 1958 to serve senior members. “We have travelers into their 80s and even 90s. Some travel as a couple and some alone,” says companyspokeswoman Ann Shannon. “We have no age limit.”If you ask travel experts, they'll tell you that age is just a number. It's a question of physical, and to a certain extent, mental ability. "Many of our travelers are retired, focused on keeping their good health, and are experienced travelers who have a good idea of what to expect, "says Sara Baer-Sinnott, president of Oldways, a food and nutrition nonprofit that operates tours. "Someone in their 40's may struggle more than someone in their 80s. "12. What is expected if Schaefer travels inCroatiathis year?A. She can rent a car to go around.B. She has to pay more insurance fees.C. She can join in all kinds of activities.D. She will receive 24/7 medical care.13. What caused Veldman to disapprove of the 93-year-old's traveling?A. His old age.B. His lack of money.C. His poor health.D. His in sociable personality.14. What do we know about Grand Circle Travel?A. It is a non-profit traveling organization.B. It offers service to a wide range of travelers.C. It has a history of more than seven decades.D. Its main customers are senior travelers.15. What is the authors altitude towards traveling old?A.

安徽省合肥市合肥一中高三最后一卷英语试题
2020届安徽省合肥市合肥一中高三最后一卷英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读选择A volunteering or gap year tripSafe, Supported Volunteering and Gap Year Trips for First-Time TravelersA volunteering or gap year trip is a great opportunity to explore other countries, to help make a difference, and to further a future career. Frontier aims to provide an authentic volunteering experience in many of the world’s most spectacular countries, while making sure that safety, support and accountability a re of primary importance. With more than 20 years’ experience in running and supporting volunteering projects worldwide, and with dedicated teams of staff in the UK and the USA, we are able to provide peace of mind for volunteer and their parents, as well as unforgettable experiences.How does Frontier support its volunteers and their families? We take the safety and security of our volunteers extremely seriously. With this in mind, here are just a few of the policies we follow:• All field staff trained in health & safety procedures• We offer a 24-hour, 7-day-a-week, emergency phone line•Weekly “Situation Report” emails for Frontier group projects, to keep friends and families of volunteers informed of news and developments on our camps.• Before accepting a volunteer onto a placement, we require them to undergo an interview with one of our travel advisers, to ensure that the volunteer understands the project, and is comfortable with all of the responsibilities required.Travel BuddiesV olunteers often feel more confident (and their parents more reassured) when travelling with someone from their own county and/ or of their own age. If requested, we will find a placement on which there are volunteers of similar ages and backgrounds. If both parties wish, we can put them in contact with each other so that they can gel lo know each other before leaving, and even arrange to fly out together.1．What is special about Frontier?A．It attaches great importance to volunteers’ safety.B．It has well trained and dedicated staff worldwide.C．It provides volunteering experience in most countries.D．It provides peaceful and unforgettable experiences.2．If parents want to track their children, they can .A．ask their travel companionsB．make emergency phone callsC．check “Situation Report” emailsD．contact field staff or travel advisers3．What type of writing is this text?A．An announcement. B．An advertisement.C．An exhibition guide. D．A travel brochure.Last year, I went WWOOFing (Willing Workers on Organic Farms) at a beautiful organic farm in the south of La Reunion. With WOOFing, volunteers exchange their time and work for food and board. I slept in a cabin in the woods with hedgehogs (刺猬) digging about in the bushes, all different coloured birds singing in the morning and endless rows of palm trees offering shade from the sun.For me, one of the best ways to get to know a new place is to work with the land, live with the locals and share meals together. It has got to be one of the best ways to travel. It is a mutually beneficial exchange where everyone involved prioritizes people and our planet above profit. You get the time and space to deepen a connection with local communities and nature.There is a lot to learn and each farm has its own unique way of doing things, depending on the environment, climate and soil. At the farm in La Reunion we planted palm trees to harvest the core of the trunk which can be eaten in salads. Before staying with the farm I had only eaten heart of palm from cans which were nothing in comparison to the real thing, fresh from the ground. When potting up the very beginnings of the palm trees, I felt grateful to be a part of the start of the trees’ cycle. I was filled with awe that something so small could grow into something so big and strong.Of course, not everyone is able to travel far afield, due to various restrictions or responsibilities back home. The great thing about the skill-share philosophy behind WWOOFing, which prioritizes people above profit, is that it’s something we can all do from our own backyard. That can be swapping French lessons with a neighbour for babysitting, or cooking a meal in exchange for a yoga class. The focus shifts from money to how we can bestsupport each other in our communities. A fair exchange can make a big difference in the world. 4．The author loves WWOOFing mainly because .A．he can get to know new places and peopleB．it is one of the best ways to travelC．he can make profits at the beautiful organic farmD．he can connect with local communities and nature5．What does the underlined word “prioritizes” in Paragraph 2 mean?A．Take something more seriously.B．Treat something more carefully.C．Consider something more important.D．Take something for granted.6．Why does the author mention “palm trees ’’again in Paragraph 3?A．To show that he learns a lot by volunteering on the farm.B．To introduce the growing process of palm trees.C．To express his interest in growing plants on the farm.D．To show his amazement at the growth of palm trees.7．What can we infer from the last paragraph?A．We should exchange what we have with our neighbors.B．We can save money by swapping labor with our neighbors.C．We can benefit each other by exchanging our time and work.D．We should volunteer to work on a farm to experience nature.Running or walking after dark, backpacking in an unfamiliar city, even taking a taxi alone in the middle of the night, can all be dangerous activities, especially for women. To offer better protection, some technology companies are looking for a way to develop or expand tools that highlight women’s safety.In Beijing, on Jun 10, China's smart jewelry brand Totwoo launched a kit called Safety, which is expected to prevent attack on women in the country.If the user feels threatened, pressing the button for four seconds will activate the device that will start recording for 10 seconds. Within 50 seconds, the device will telephone and send text messages to three emergency contacts to inform them, providing a location, first-aid information and audio recordings. Once a contact responds, the device shakes and lights up toinform the user. The user can disable the alarm by pressing the button three times in succession.Around the diameter of a bottle cap, the waterproof piece of jewelry can be attached to a bag, a key or even worn as a necklace. “In Chinese culture, certain jewelry is sometimes worn as a symbol of safely. Our product brings some truth to that,” says Wang Jieming, who founded Totwoo in 2015. It makes sense that the company decided to model the jewelry in the shape of an apple, the name of which in Chinese is “ping guo”, sharing the same pronounced ping as “ping’ an”, the Chinese word for “safety”.Cooperating with China Mobile, the small core module uses a remote SIM, by passing the need for a physical SIM card. It has certified wireless-charging technology similar to the system used by Apple. Supporting navigation systems such as GPS, Beidou and GSM base station positioning, it car provide accurate location information.Xin Yang, head of the International Security Defense College in Beijing, a private security training school established in 2011, says an independent device can enhance women’s safety in an emergency, because “mobile phones are often the first item an attacker wi ll attempt to grab or destroy”.8．Which of the following is right about the device?A．The user can make video and audio recordings with the device.B．The device can be switched on and off within minutes.C．The user can confirm a contacts response without text messages.D．The device is technically supported by big companies such as Apple.9．What is the advantage of a smart jewelry over other devices according to Xin Yang? A．It’s easy to carry and operate.B．It looks beautiful on women.C．It symbolizes safety in Chinese culture. D．It avoids being targeted by an attacker. 10．What is the author’s attitude towards the future of the device?A．Doubtful. B．Favorable. C．Uncertain. D．Objective. 11．What is the text mainly about?A．Women can be fashionable and safe.B．A smart jewelry promotes women’s safety.C．Women’s safety raises widespread concern.D．Technology companies find a new way to save women.“There’s no place like home.” This English saying has much truth in it: the best placeto be is surrounded by our treasured possessions and our loved ones and with a roof over our head. And for many young adults, it’s the only affordable place to stay; some place where they can receive first- class service from mum and dad. But this comes at a price!In some countries, it’s quite traditional for people in their late teens and early 20s to live at home with their parents, but in other places, flying away the nest to start their own independent life is very desirable. But there’s been a growing trend, in the UK at least, for young people to return home to live —or not to leave home at all.According to the UK’s Office for National Statistics, about a quarter of young adults aged 20-34 live at home, and that figure has been growing. A survey by a price comparison website found that 18% of adult children in the UK said they were moving back home because of debt, compared with 8% last year. More young people had lost their jobs, and others couldn't afford their rent compared with the previous year. So, it’s easy to see why they’re increasingly becoming home birds.The BBC’s Lucy Hooker explains that many returning adult children enjoy home comforts. These include cooked meals, a full fridge and cleaning, as well as their bills being covered by what is commonly called “the hotel of mum and dad”. But for the “hoteliers”, that’s mum and dad, the survey found the average cost to them has gone up sharply, and that they are sacrificing luxuries and holidays to look after their “big kids”. Emma Craig from Moneysupermarket says “they’r e trying to look after their children more. If your child comes home and you see them struggling financially, you feel more awkward asking them for rent or lo contribute.With parents splashing out（花费）around ￡l,886 on takeaway food, buying new furniture and upgrading their Wi-Fi for the benefit of their children, it’s easy for the returning children to put their feet up and make themselves at home. That's before they learn a home truth that one day it might be their own kids who'll be checking into the hotel of mum and dad! 12．Which of the following statements is true according to the text?A．The main reason for their moving back home lies in parents' service.B．Different countries have different traditions.C．More and more young people live with parents in the UK.D．Young people desire to live independently in all countries.13．Why do more young people choose to stay at home?A．They are struggling financially.B．They want to keep their parents company.C．They can't afford to buy their own house.D．They want to enjoy home comforts14．What influence does the trend have on parents?A．They have difficulty making ends meet.B．They feel happy with their children around.C．They feel awkward asking their children for rent.D．They give up their own life to take care of their kids.15．What is the best title for the text?A．A new trend in the UK.B．The hotel of mum and dad.C．There’s no place like home.D．Everything comes at a price.二、七选五Asymptomatic infections（无症状感染）of the COVID-19 can be hard to track and chances of such virus carriers spreading the virus are simply equal. 16．Therefore, to protect yourself from those potential infections, you need some basic protective measures to take care of your health and the others' as well.Wash your hands frequently.Cleaning your hands regularly and thoroughly with an alcohol-based hand rub or washing them will soap and water can help kill viruses that may be on your hands.Maintain social distancing.Maintain at least I meter (3 feet) distance between yourself and anyone who is coughing or sneezing. 17．Being loo close, you expose yourself to the risk of breathing in the droplets, including the COVID-19 virus.18．Hands touch many surfaces and can pick up viruses. Once contaminated（弄脏）, hands cam transfer the virus to your eyes, nose or mouth. 19．Seek medical care early if you have fever, cough and difficulty breathing.If you have a fever, cough and difficulty breathing, seek medical attention and call in advance. Follow the directions of your local health authority who may have the most up to date information on the situation in your area. Calling in advance will allow your health careprovider to quickly direct you to the right health facility. 20．A．This will also protect you and help prevent spread of viruses and other infections. B．Avoid touching eyes, nose and mouth.C．Thus, the goal of preventing the possible spread of COVID-19 can be easily achieved. D．From there, the virus can enter your body and can make you sick.E.Cover your mouth and nose with your bent elbow or tissue when you cough or sneeze.F.Many people who are infected experience mild illness or no symptoms at all, but it can be more severe for others.G.When people cough or sneeze they spray small liquid droplets from their noses or mouths which may contain virus.三、完形填空It was only a dollar. Belscher 21 it on the floor. He could easily have 22 it without thinking twice. 23 , he brought it to his English teacher, Mattison.

2020届合肥市第一中学高三英语下学期期末试卷及答案
2020届合肥市第一中学高三英语下学期期末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AYou have to praise the smoothness（顺畅）of ants on the move. No matter how many of them are going toward a place, there's never a hold-up. A new research paper shows how ants keep traffic flowing by changing their behavior to meet changing conditions.For their experiments, researchers from the University of Toulouse focused on Argentine ants, animals that often move from colony（群落）to colony depending on where the food is. Making use of Argentine ants' talent for fast travel, the researchers built bridges connecting their colonies. The bridges were different in width from a fifth to three-quarters of an inch. The colonies, too, were of different sizes, ranging from 400 to more than 25,000 ants.Then the researchers sat back andmonitoredthe traffic. To their surprise, even when those narrower bridges were full of ants, there were no "traffic accidents". "When the number of ants on the bridge increased, ants seemed to be able to understand the situation and adjusted（调整）their speed accordingly to avoid making the traffic flow stop. "the authors note. "Moreover, ants avoided entering a busy road and made sure that the bridge was never too packed to cross.”The lesson for humans? The traffic problem may lie in our inability to adjust our driving habits for the good of the whole. Driving is fun when there are few cars on the road. Then the traffic moves very slowly. And yet, some impatient driver still acts like he's alone on the road.The research suggests that projects, like the ever-widening of highways, may never free us from traffic jams. As long as we drive along with our own habits, no matter how many other people are on the road, we'll always end up in a traffic jam. Indeed, less space may actually be a good thing. It leaves less room for individual choice and forces us to take a page from the driving book of ants.1. What is Paragraph 2 mainly about?A. The results of the experiments.B. The purpose of the experimentsC. The preparation of the experiments.D. The requirements of the experiments2. What does the underlined word "monitor" in paragraph 3 probably mean?A. watch and check.B. seek and improveC. design and planD. discuss and practise3. What is the best title for the text?A. Is widening highways a solution?B. Why don't ants need traffic lights?C. Can we learn safe driving from ants?D. What can ants teach us about traffic jams?BThe connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conductedin Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.The engineers at the Massachusetts Instituteof Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater.＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.4. What is the first paragraph mainly about?A. A new study of different plants.B. A big fall in crime rates.C. Employees from various workplaces.D. Benefits from green plants.5. What is the function of the sensors printed on plant leaves by MIT engineer?A. To detect plants’ lack of waterB. To change compositions of plantsC. To make the life of plants longer.D. To test chemicals in plants.6. What can we expect of the glowing plants in the future?A. They will speed up energy production.B. They may transmit electricity to the home.C. They might help reduce energy consumption.D. They could take the place of power plants.7. Which of the following can be the best title for the text?A. Can we grow more glowing plants?B. How do we live with glowing plants?C. Could glowing plants replace lamps?D. How are glowing plants made pollution-free?CRain is vital to life on Earth. However, rain isn’t just made of water anymore—it’s partly made of plastic.Millions of tiny pieces of plastic, called microplastics, are wandering around Earth’s atmosphere and traveling across entire continents according to a study published in one journal on April 12.Microplastics are plastic particles less than 5 millimeters in diameter and come from a number of sources. Plastic bags and bottles released into the environment break down into smaller and smaller bits. Some microplastics are produced deliberately to provide abrasion(研磨)in products, such as toothpaste and cleansers. Another major source is your washing machine. When you wash clothing, tiny microfibers get washed away with the wastewater. Even though the water is treated by a wastewater plant, the microplastics remain,and they are released into the sea.Plastic rain may remind people of acid rain, but the former is far more widespread and harder to deal with. The tiny particles, too small to be seen with the naked eye, are collected by the wind from the ground. They are so light that they stay in the air to be blown around the globe.
