2020年安庆一中高三英语模拟试卷及答案解析
2020年安庆一中高三英语模拟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AWhat to Eat—and What to Skip—When It Comes to Takeout FoodIf the burden on your wallet doesn't bother you much, the effect your takeout habit can have on your waistline just might arouse your attention. Here's the best and worst of the lot for your belly.Steamed Vegetable Dumplings: Order This.When she orders Chinese, registered dietitian nutritionist Elisa Zied gets an order of steamed vegetable dumplings. "I often pair them with either chicken and broccoli in brown sauce（I ask for a little saucemade without sugar）or steamed shrimp dumplings," she tells us.Crab Wontons: Not That!When you deconstruct crab wontons, it's easy to see why they're a "Not That!" The inside is filled with crabmeat and cream cheese（which is just a fancy, spreadable fat）.The wonton is made of refined flour, egg and salt and the crispy（脆的）coating is a result of a deep oil bath.Peking Duck: Order This.Most of the fat from the skin flows out of the duck over the course of cooking, making this a healthier choice than most of the stir-fry dishes available. Order a side of steamed vegetables and serve it with a small scoop of brown rice. Done and done!Sweet and Sour Anything: Not That!Anything with “sweet and sour” in its title is a powerful cue that something has been deep-fried and covered in a sickly-sweet pink sauce. If you pair your selection with a side of rice, you're looking at a 1,000-calorie meal.Summer Roll: Order This.Summer rolls are steamed instead of fried—and typically filled with lean proteins and vegetables, making them a winning appetizer in our book. Pair them with an order of edamame（毛豆）and a broth-based soup for a satisfying, filling meal.Spring Roll: Not That!Spring=deep-fried, which is why we say to skip them! They're filled with fat and calories your belly doesn't need.1.What kind of cooking method should be skipped according to the text?A.Steaming.B.Stir-frying.C.Deep-frying.D.Boiling.2.Which of the following suits as a good starter for a meal?A.Chicken and broccoli.B.Steamed vegetable dumplings.C.Peking duck.D.Summer rolls.3.Where can the text be found?A.In a recipe.B.In a guidebook.C.In a science fiction.D.In a health magazine.BIn 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 theanimals," he said.4. 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.5. 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.6. 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.7. What does the underlined word "steward" mean in the last paragraph?A. Farmer.B. Master.C. Guardian.D. Explorer.CAs one of the world’smost popular cultural mediums, cinema is at the leading position at the Taihu World Cultural Forum(论坛), an annual event that aims to improve cultural exchanges. So far this year, Chinese box office has already topped 58 billion yuan, the China Film Administration said. This indicates that China, the world’s second-largest movie market, is closing the gap with the United States, the world’s top cinema market.Cao Yin, director of the program center at China Movie Channel, said that China has 67,000 cinema screens. the most of any country, and the number is expected to increase to 80,000 by the end of next year. Saying that China has signed coproduction agreements with 22 countries (including the United States, Canada, Japan. India etc.) ,Cao added it has deepened cinematic exchanges between Chinese filmmakers and their foreign counterparts (同行).With the country’s huge native market, which produced more than 1,000 films in 2019, Hong Kong directorStanley Tong said he believes foreign filmmakers will increasingly seek cooperation with China. “International coproduction will become an important platform to send Chinese stories oversea and give us a broader vision of creation,” Tong said.Recently, over 80 percent of the world’s top 100 highest box-office titles have been action films. Tong said the films, in which plots are basically secondary to shining stunts (特技), is one of the easiest ways to appeal to foreign audiences. But it has been a decades-long struggle for Chinese filmmakers to sell their stories overseas. When asked what kinds of Chinese films would have the most global appeal. Yan Zhaozhu, chairman of the Taihu World Cultural Forum, said stories that address universal issues, such as environmental protection and climate change, are perhaps the best options.8. What is the purpose of the Taihu World Cultural Forum?A. To strengthen cultural exchanges.B. To build more cinemas in China.C. To invite more tourists to Taihu.D. To attract more international investment.9. What can we infer about Cao Yin’s opinion in Paragraph 2?A. Chinese box office has already overtaken the United States so farB. The screens of Chinese cinemas will be world-leading in the futureC. China has signed the most coproduction agreements with other countriesD. There will be more and more cooperations between Chinese filmmakers and other countries.10. How do Chinese filmmakers feel about selling their movies to the world right now?A. Easy.B. Disappointed.C. Challenged.D. Confused.11. What is the best title for the text?A. Box Office: Unclear FutureB. China: Top Second Movie MarketC. Cinema: The Leading Cultural PositionD. Chinese Filmmakers: Severe Competition SituationDIt’s a little before8 a.m. when Mathias Schergen pushes open the side door at Chicago’s Jenner Elementary Academy for the Arts. He walks down the hall toward the office to sign in. It’s the same routine he’s had asJenner’s art teacher for nearly a quarter century. “It’s going to be a good day,” a colleague calls out. “It’s a good day.” They hug. It seems like a typical Friday. Except it’s not. After 23 years at Jenner Elementary, Schergen is retiring. Even on his last day, there are still art projects to finish.Schergen leaves behind a richlegacyat this school. He’s won grants (拨款) for art projects. He turned an empty classroom into a museum. He’s pushed his students to make art about their lives. And he was awarded a Golden Apple — the most honorable teaching award in Chicago. But it wasn’t always easy. For years, Schergen taught in one of the city’s toughest neighborhoods. “When I first got my room, I noticed there were bullet holes in the window. That made me nervous,” he says. So he stuffed Beanie Babies in the holes to make it “look kind of funny”. “I didn’t even tell my wife for a whole year,” he says. “I didn’t want her to know.”With one hour to go, Schergen piles the chairs and sweeps the floor. He cleans out the sink for the last time. Fifth-grader Deontae Barnes, one of his best helpers, has watched him say goodbye all day. He wanders in the doorway. “Ah, come here, son,” Schergen says, signaling him over. He bends down for a hug. “Thank you for making these last days special and being a help to me.”When Deontae leaves, a reporter asks Schergen: When your kids ask why you’re retiring, what do you tell them? “I just tell them that grown people have dreams too,” he says. “I have other things in my life I have to do. It’s time. It’s just time.”12. Why is it a special Friday for Schergen?A. He was retiring on that day.B. He won an honor for his school.C. He was interviewed by a reporter.D. He received a Golden Apple award.13. What does the underlined word “legacy” in Paragraph 2 refer to?A. Art projects.B. Great achievements.C. Respect from students.D. Change in teaching.14. What made Schergen nervous when he first got to the school?A. Safety concerns in the school.B. The poorly-equipped classroom.C. Being misunderstood by his family.D. Students’ poor academic performance.15. What is the best title for the text?A.A Typical Day for an Art TeacherB. Time for Art ProjectsC. A Teacher’s Final Day at SchoolD.

How do they help you to understand what you are reading?In Jane Yolan'sOwl Moon,a girl explores with her father on a snowy night. She longs for this special night.And she's amazed when she sees an owl.Have you felt longing before? Amazement? Well, if you have, it helps you have a sense of agreement. When we can put ourselves inside a story we can understand it better. Our brain tells us,"Oh, this girl's experience is a bit like mine."And boom! We can relate to her.But this skill is not born in us.So young kids have to learn it.Pictures and images help young readers to understand and recognize feelings.Readers feel joy when seeing the smiling faces of friends.They feel fear when turning the page to find a scary monster. They are just pictures,but the feelings are real. This skill, to understand the thinking and feeling of others, is what researchers call "theory of mind".For example, think about the faces of people and animals in stories. The Big Bad Wolf's scary teeth. The 'o' shape of a surprised character's mouth. Or big, wide eyes like the girl inOwl Moon.By noticing the faces,readers can start to figure out what it feels like to be that character.And that helps to figure out how people feel and think in real life.But most young readers don't go into deep,scary woods.And some may not go to the beach or play basketball.In the bookYo!Yes?two kids meet and play ball. The kids start the story on opposite pages.But as the story goes on,they get closer until they are together.Some young readers might not play basketball, but they can read the clues on the page to figure out how the kids are feeling.And some readers might not like the game,butthey can feel excited for the characters because of how the characters look and move.4. What can we learn from the second paragraph?A.Owl Moontalks about the exploration of the Moon.B. The feeling of"amazement"is a sense of agreement.C. Readers are blessed with the ability to interpret others.D. Readers with similar experience understand the story better.5. Which of the following might help readers develop"theory of mind"?A. True feelings.B. Smiling faces.C. Picture books.D. Reading skills.6. Young readers can go deeper into a story by________.A. tracking the plotB. developing new skillsC. sharing similar hobbiesD. analyzing the background7. What is the text mainly about?A. How thinking influences reading.B. How readers improve reading skills.C. How emotions help enhance reading.D. How kids figure out the clues of stories.CAt the foot of the Tianmu Mountain in Zhejiang, a homestay (民宿) is attracting travelers from far and wide, which has won architectural (建筑学的) medal at the 2021 German iF Design Awards.The owners of the homestay are a couple in their late 30s who decided to return to their hometown three years ago. Li Xiumei used to be in charge of a division at a company in Hangzhou, and her husband was a sales director. It was an ordinary situation where Li’s husband was on business trips a lot and Li worked overtime on weekends. City life sometimes is not easy.In 2018, they quit jobs and went back to Dongtianmu village, which lies in a forest of bamboo. The first time they drove into the village was one late afternoon. The cooking smoke was rising from the foot of the mountain, which gave them a very different feeling form thecity.The homestay was built beside her husband’s old countryside house. The old house is preserved (保留), while a brand-new building was built on its side and the whole site is made up of for courtyards. It has been updated to have a hall, a tea room, a kitchen, a dining room. Japanese cherry trees are planted in the east courtyard. A swimming pool is placed in the west courtyard, with a bar located on one side.Li and her husband love gardening and music, and their new home gives them enough space to continuetheir interests and relax in the heart of nature. Li wants to share the quiet country life, so she makes her new home a homestay. In 2019, the homestay became an online hit after guests shared their experiences on social media. “The longer I stay here, the more I feel it was the right choice to come back, and this is more meaningful than making money,” Li says.8. How did Li feel about city life?A. Satisfied.B. Tired.C. Attractive.D. Noisy.9. What impressed the couple when first driving to the village?A. The smoke of cooking.B. The forest of bamboo.C. The smell of the village.D. The feeling of loneliness.10. What can we infer about the homestay from paragraph 4?A. It is ancient and broken.B. It can hold many guests.C.

Living in the countryside.D. Developing the economy of cities.DCoke was introduced by the Coca Cola company in 1886, making it a rather true andtested favorite of generations of people in over 200 countries. This list should give you some ideas on how to get more from your coke than usual.. Coca Cola is an excellent rust buster (除锈剂). If you have a bunch of small rusty objects, put them in coke overnight and give them a goodscrubin the morning. Coke helps to break down the rust, making cleaning much easier. Be sure to throw out the used coke when you are done with it or you might be taking a trip to the doctor.. Like the previous item, the citric acid (柠檬酸) in coke makes for an excellent window cleaner. This is especially useful for car windows. Pour a can of coke over the window and rub the window, then wipe it off with a wet cloth to remove any sugary matter from the sugar in the drink. As coke is fullof sugar, you should clean the sticky matter off the window glasses, or it will be not a cleaner but a dirt.. For those of you who live in areas where skunk (臭鼬) smells can be an issue from time to time, one can of coke added to water with detergent (清洁剂) really helps to break the smell down. If you have been sprayed, stand in the shower and cover yourself from head to toe with coke — wait for a few minutes, then wash yourself with a shower. Coke is an excellent hair treatment so you get two tips for the price of one with this item!. Pots can sometimes get black on the bottom. The black is almost impossible to remove; this is caused by over-cooking. To remove the black and renew your pot, pour in a can of coke (or as much as you need to cover the blackened area by an inch) and put it on the stove on a low heat. After an hour or so, wash the pot as normal.12. What does the underlined word “scrub”in Paragraph 2 probably mean?A. Start.B. Cleaning.C. Shake.D. Example.13. What is important while using coke to clean car windows?A. Use a dry cloth.B. Rub the window lightly.C. Don’t pour too much coke.D. Clean the sugary matter thoroughly.14. For which purpose does coke have to be mixed with other material?A. To get rid of the black on the pot.B. To breakdown the rust,C. To remove smells.D. To clean windows.15. What type of writing is this text?A. An advertisement.B. A review.C. A news report.D. A practical guide.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。

1．阅读下面的文字，完成下面小题。 教堂司事 （英）毛姆 圣彼得教堂下午有一场洗礼，所以奥伯特·爱德瓦·佛曼还穿着他的司事长袍。他总是把新袍子放在做丧礼或婚礼的时候才穿，所以，现在他所穿的只是稍微次一等的。穿这袍子，他感到自傲，因为这是他职位尊严的标志。 司事现在是在小礼堂等着牧师结束他的仪式，这样他就能将这里收拾整齐然后回家。 这位牧师是最近才任命的，四十来岁，红光满面，是个精力充沛的人。而奥伯特·爱德瓦还是为先前的牧师感到遗憾，那是一个旧派的教士，从不大惊小怪，不像现在这位，样样事情都要插上一手。 不久他看到牧师走了过来。 “佛曼，您能到小教堂里来一会儿吗，我有些事情要同你说说。” “好的，阁下。” 牧师将奥伯特·爱德瓦领进了小教堂。 奥伯特以一种谦恭而又尊严的姿态站着。在当司事之前他当过仆人，但是都是在非常体面的人家。开始是在一个富商家当跟班，后来在一位寡居的贵夫人家他升到了管家的职位，圣彼得教堂司事职位出现空缺时他已经在一位退职的大使家里当总管，手下有了两个人。他高大，瘦削，沉稳而自尊。看起来，不说是个公爵，但至少也是老派戏班里专门扮演公爵的演员。他老成，坚定，自信。 牧师神彩奕奕地开口了。 “佛曼，我了解到一件非同寻常的事情。我非常惊讶地发现，你竟然既不能读也不能写。” 司事的脸上没有显露出任何窘困的神色。 “以前的牧师就知道这情况，阁下。”他回答说。“他说这无关紧要。开头那家厨师曾经想要教我，但我好像在这方面实在不开窍。” “佛曼，不是我要苛求于你，”牧师说，“我给你三个月时间，到那时你要是还不能读，不能写，那恐怕就得叫你走人。” “我感到非常抱歉。我是一条再也不能学新花招的老狗了。不会读不会写，好多年来我也活得很好。” “这么说，佛曼，我只好说你得走人。” “好的，阁下。” 但是，当奥伯特·爱德瓦以他通常的礼貌在牧师离开后关上了教堂的门以后，他再也无法保持住那种庄重了，他的嘴唇哆嗦着。他穿上了他的夹克，帽子拿在手里，走出了教堂。在深深的忧伤中，他没有走向那条往家走的路。他走得很缓慢。心情非常沉重。他不知道自己究竟该怎么做。就在此刻，他觉得要是有支烟抽，或许会给他一点安慰。既然他从不带烟，他就四下里寻找着，看哪里可以买一盒。他没有看到卖烟的店铺，于是就往下走去。这是一条长长的道路，可就没有能卖香烟的店铺。 “这真有点儿怪。” 为了确信，他又重新在街上走了一遍。没有，确实不用怀疑。 “我不会是唯一一位在这条街上走过而想到要抽烟的人的，”他想。“如果哪个家伙在这里开爿小店，卖点烟草、糖果之类的，准能赚钱。” 他为此遽然一震。 “这就是念头，”他说，“真是奇怪，事情就是在你最没有想的时候这样来了。” 他将这件事情左思右想了一番，第二天他去了那条街，而且很幸运地找到了一家待出租的店铺。二十四小时后，他将这家店铺拿了下来，一个月以后，一爿卖香烟和书报的店铺就开张了。他的妻子认为这件事很糟糕，简直是堕落，但是他回答说，人必须跟着时代变。 奥伯特干得很不差。过了一年左右，他突然开窍——他想，为何不再开第二家商店，找个人来经管。于是他又去寻找长长的，还没有香烟店的街道，果然找到这样的街道，还有可以出租的店铺，他又拿了下来。然后，他开始走遍全伦敦，只要找到一条长长的，还没有香烟店但有店铺出租的街道，他就拿下来。这样，在十年时间里，他一连开了不下十家店铺，赚到了大笔钱财。每个星期一，他就将一个星期收到的钱统统收拢起来存到银行去。 有一天早晨，正当他在将一扎扎钞票和一大口袋银币交进银行的时候，一位银行出纳告诉他说，他们的经理想要见他。他被引进一间办公室，经理同他握手。 “佛曼先生，你所存进来的钱，已经稍微超过三万磅了。这是很大一笔钱存款了，最好是用它来投资。” “我可不想冒任何的风险，阁下。我知道，放在银行里很保险。”佛曼先生富态的脸上出现了疑虑。“我从来没有接触过股票和分红，我只是想要把这些钱存放在你的手里就行了。” 经理笑了。“所有的一切我们都会帮你做的。你以后只要在传票上签名就行了。” “这我倒能做，”奥伯特不无疑虑地说。“不过，我怎么知道到底签的是什么呀？” “我想你总应该会阅读吧，”经理以玩笑的口吻激烈地说。 佛曼先生给了他一个解除疑虑的微笑。 “哦，阁下，事情正是如此。我真的不能读也不能写，我只会签自己的名字，而这也是我在经营了生意以后才学会的。” 经理大吃一惊，从他的椅子上跳了起来。 “你是说，你建立了这么重要的生意，赚了三万磅的财富，却不会读也不会写？我的天呐，我的好人，如果你要会读会写，那你现在还会成什么样啊？” “我可以告诉你，阁下，”佛曼先生说，一丝笑容浮上了他依然高贵的面庞。“那我就还是内维尔广场圣彼得教堂的司事。” 1．下列对本文相关内容和艺术特色的分析鉴赏，不正确的一项是（ ）
