2020届中央民族大学附属中学高三英语期中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AIt’s the time of year when we start hiking. As you pack, remember to bring your smartphone. Whether you’re going on a short walk or a long trip, there are a handful of apps that can help.MapMyHikeThis app tracks where you're hiking so you have a mapof your route at the end of the hike. It can also track other fitness information like the distance traveled, speed, pace, and even calories burned. You can save the data for your hike, so you can always access the route you look as well as track improvements to your workout. GaiaGPSYou don't always have cellphone service when hiking, but you always want to know where you are. The GaiaGPS app provides that information. Download maps of different parts of the world, and access the GaiaGPS app in the middle of even the most remote trails. The GPS function makes using the maps simple, and the app will also point to areas of interest.Backpacking ChecklistOne of the worst things is being way out on a trail only to discover you left behind something important. That's why checklists are the best. This checklist app helps you build a customized(定制的) list of things to take with you. Organize different lists based on trail lengths or requirements. Track all your essential items by weight and where you can find them.WildObsUsing WildObs, you can record your observations of plants and animals and add them to the database. You can ask the community to help you identify something and keep track of everything you've met, and most importantly, you can become a citizen scientist. By recording what you've seen with this app, you're helping scientists keep track of what's happening to the natural world.1. What can you do with MapMyHike?A. Record your walking speed.B. Design a suitable hiking route.C. Locate popular tourist attractions.D. Store the data of your daily activities.2. What is WildObs intended to do?A. To provide survival skills.B. To lead the way.C. To identify wildlife.D. To help make preparations.3. Which app is most useful before hiking?A. GaiaGPS.B. MapMyHike.C. WildObs.D. Backpacking Checklist.BDisease-carrying mosquitoes can spread diseases without affecting themselves. Nearly 700 million people get a mosquito-borne illness each year, which results in over one million deaths. Humans experience continuous pressures from disease-carrying mosquitoes in many parts of the world, so we have to find ways to fight against those insects because they keep getting scarier.Even though DEET remains the most commonly used, and most powerful, mosquito repellent ever developed, scientists are actively pursuing effective products based entirely on plant oils. While DEET is an effective contact repellent, many people dislike the oily feel and smell on their skin, and sometimes some people are sensitive to it. Consumers are always interested in alternatives to DEET and other synthetic repellents, so there are numerous natural repellents on the market.In his lab atIowaStateUniversity, Dr. Joel Coats and his team have successfully tested these repellents against three species of dangerous mosquitoes. The first group of the new repellents act through the air. These chemicals have a vapor action that provides protection, and they are called “spatial” repellents, since they act through space. These are potentially most useful in backyards, parks, and houses. The other group are the classic ones that stop insects from standing on a treated surface, such as human skin, clothing or tents; collaborators at the USDA-ARS and BioGents have conducted testing with humans to confirm the effectiveness and identify the very best ones.The new repellents were designed and made from the natural materials in plant essential oils. They maintain many of the advantages of the natural repellents: They are fully biodegradable, with no ecological concerns or environmental wastes, and generally considered safe like the thousands of types of plant essential oils used in the flavor and perfume industries. However, thorough testing will be conducted to determine if they are truly non-poisonous because there is still no enough evidence.4. What does the author mainly want to show in paragraph 1?A. The way mosquitoes spread disease.B. The high death rate of mosquito-borne illness.C. The difficulty of fighting disease-carrying mosquitoes.D. The urgency of finding tools to fight against mosquitoes.5. What is a disadvantage of DEET?A. It won’t be effective for long.B. It can’t be applied universally.C. It causes discomfort to the users.D. It greatly harms people’s health.6. What can we learn about the second group of the new repellents?A. They can kill mosquitoes indirectly.B. They are mainly used in the open air.C. They are more effective on human skin.D. They can prevent mosquitoes from contacting users.7. What’s the author’s attitude to the new repellents?A. Subjective.B. Objective.C. Doubtful.D. Disapproving.CMark Bertram, 46, lost the tips of two fingers at work in 2018 when his hand became trapped in a fan belt. “It's life-changing but it's not life-ending,” he says. “Doing work is harder now. Everything is just a little different.”After two surgeries and occupational therapy, Bertram decided to make light of his condition by asking Eric Catalano, a tattoo (纹身) artist, to create fingernail tattoos. The idea made everyone in the studio laugh—until they saw the final result. “The mood changed,” Catalano recalls from his Eternal Ink Tattoo Studio. “Everything turned from funny to wow.”When Catalano posted a photo of the tattoos, a pair of fingernails that looked so real that no one could believe their eyes, he had no idea the image would eventually be viewed by millions of people around the world.The viral photo pushed Catalano, 40, further into the world of paramedical (辅助医疗的) tattooing. Now people with life-altering scars come from as far away as Ireland to visit his shop. They enter Eternal Ink looking for the artistic healing they saw online. Using flesh-toned (肉色的) inks and a needle, Catalano transforms his clients' view of themselves.Leslie Pollan, 32, a dog breeder in Oxford, was bitten on the face by a puppy in 2014. She underwent countless surgeries to correct a scar on her lip.“Plastic surgery gave me no hope,” she says. “So I looked for other options.” She ultimately traveled six hours to meet with Catalano. He hid Pollan's lip scar, giving her back a piece of her confidence.“ You don't understand until you've been through it,” Pollan says. “It made me have a different look on life.”Catalano performs up to eight reconstructive tattoos. While he charges $100 per regular tattoo, he doesn't charge for paramedical tattoos. “Financially, it doesn't make sense,” Catalano says. “But every time I see that emotion from my customers, I'm 100 percent sure this is something that I can't stop doing.”8. What best describes people's attitude when first hearing of fingernail tattoos?A. Indifferent.B. Ridiculous.C. Confident.D. Surprised.9. What did Catalano do to help Leslie Pollan?A. He drew an artistic puppy.B. He inked scars on her face.C. He created a lip tattoo.D. He performed plastic surgeries on her.10. What can we infer from the passage?A. Cosmetic surgery is of no use.B. Tattoos earn Mark Bertram a good fame.C. Catalano is a kind and generous person.D. Fingernail tattoos are popular around the world.11. What could be the best title for the text?A. A Life-changing EventB. Miracle TattoosC. An Amazing ArtistD. A Promising BusinessDMany teens may feel anxious sometimes. It’s the kind of nervousness that makes you bite your nails before a big test. We spend more time online than we should. We feel good about ourselves or bad based on how many Likes and Followers we get on social media. Young people are developing a false view of life.On the screen, we see what people want to show us. People usually only post photos where they are looking their best. They are surrounded by friends and seem that they are having a great time. No one seems sad or lonely. In short, life isfabulous. But sooner or later, our young people compare their real life to it. They find that theirs doesn’t seem as fun or exciting and grow worried that they may be missing out.No wonder teachers are reporting more anxious students. It’s reported that a lot more college students feel ―overwhelming anxiety. The percentage jumped from 50% in 2011 to 62% in 2016. Anxiety is now the most common mental-health problem in my country. It affects nearly one-third of teens and adults.Certainly, we can’t blame it on social media alone. We expect toomuch from our children and a lot of these expectations aren’t reasonable. Their schedules are packed with sports, clubs and homework. They don’t have enough free time. We want our children to succeed, and we don’t care how much it costs.As parents, we must have more balance. On one hand, we push too hard, and on the other hand, we make life too easy for children. We shouldn’t and can’t promise our children that they will always be happy. We shouldn’t try to protect them from the problems of everyday life. Let them solve the problems in person.12. What is the text mainly about?A. What causes teens’ nervousness.B. How to deal with teens’ anxiety.C. What a view of life means to people.D. How to treat social media appropriately.13. What does the underlined word “fabulous” in paragraph 2 mean?A. Wonderful.B. Encouraging.C. Anxious.D. Doubtful.14. Why does the author mention the numbers in paragraph 3?A. To draw teachers’ attention.B. To show teachers’ mental problems.C. To present the seriousness of teens’ anxiety.D. To show adults have more problems than teens.15. What should parents do to help their children out?A. Try to meet their expectations.B. Help them with their homework.C. Give them more free time to play sports.D. Allow them to solve their own problems in life.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。

第I卷阅读题一、现代文阅读(35分)（一）论述类文本阅读（9分，每小题3分）阅读下面的文字，完成1-3题同其它林木相比,竹子颇有一些独特之处,如虚心、有节、清拔凌云、不畏霜雪、随处而安等等。

这些特点,很自然地与历史上某些审美趣味、伦理道德意识发生契合,进而被引入社会伦理美学范畴,成为君子贤人等理想人格的化身,并对中国传统文化的发展产生深刻的影响。

不仅春风得意的封建宠儿常常以竹来互相吹捧或以竹自诩,那些落泊荒野的书生和隐居“南山”、待价而沽的名士,也普遍寓情于竹、引竹自况。

在这种独特的文化氛围中,有关竹子的诗词歌赋层出不穷,画竹成为中国绘画艺术中一个重要门类,封建士大夫在私园、庭院中种竹养竹以助风雅,亦成为普遍风气。

最早赋予竹以人的品格,把它引入社会伦理范畴的,恐怕要算《礼记》了。

《礼记·祀器》中说:“其在人也,如竹箭之有筠也,如松柏之有心也。

二者居天下之大端矣,故贯四时而不改柯易叶。

”魏晋时期政治局势反复无常,文人士子意气消沉,以阮籍、嵇康为代表的一批失意文人,为逃避现实,不与当权者合作,遁隐竹林,借竹之高标、清姿佐己之风流,在当时社会引起很大震动,对后代封建文人的行止也产生了莫大影响,可以说,敬竹崇竹、寓情于竹、引竹自况,竹林七贤乃是“始作俑者”。

自此以后,中国的文人士大夫便与竹子结下了不解之缘。
