Food loss and waste exist and millions of people are still hungry. The food wasted globally every year could feed these hungry people. Various school activities were carried out for this reason. Young volunteers put up posters and signs promoting food saving on campus to increase awareness of respecting food labor and valuing food among students. Also,class meetings were held to make a change in the students ’ attitude and encourage them to become eco-pioneers. Through the campaign, we have become more aware that there is no excuse for wasting food. To save food is a traditional virtue in China, which we should never forget. 【听力原文】 (Text 1) W: What was that? Could you say that again, please? This bus is really noisy.

2022届东北三省三校（哈尔滨师范大学附属中学东北师大附中辽宁省实验中学）高三第一次联合模拟考试英语试卷学校:___________姓名：___________班级：___________考号：___________一、阅读理解Whether you’re travelling to the islands or the mountains of Thailand, you’re likely to spend at least one night in its capital city on the way. Bangkok might be noisy and polluted but it’s also an exciting city with plenty of things to see and do. Why not make it a longer stay?Where to stayThe Khao San Road was a famous traveler spot even before Leonardo di Caprio’s character in the film The Beach stayed there. But it’s noisy, not very pretty and not very Thai. For something more authentic, Phra Kanong offers an alternative place to stay, with its fantastic street markets where Bangkok people eat, work and live every day. It’s not as convenient for the main tourist sites, but it has a Skytrain station so you can be at the Grand Palace in 20 minutes.How to get aroundBangkok’s traffic can be a nightmare. Sure, you can easily take a taxi—if you want to spend hours stuck in traffic jams—but there are two much better ways to get around the city. To explore the temples and historical sites, catch an express boat or a longtail boat along the Chao Phraya River and the canals. For the modern part of the city, the Skytrain is a fast, cheap way to travel from the river to the shopping malls and nightlife of Sukhumvit, and the famous Chatuchak street market.What to doAfter you’ve seen the main sites like the Giant Buddha at the temple of Wat Pho and the spectacular Grand Palace, and shopped at Chatuchak market, check out the snake farm and watch the live snake show. You can even touch a snake yourself if you want to!1．What is special about Phra Kanong?A．Its convenience for tourists.B．Its real Thai lifestyle.C．Its live snake show.D．Its appearance in a famous movie. 2．Which may be the best transport to explore the modern area of Bangkok?A．An express boat.B．A longtail boat.C．A normal taxi.D．The Skytrain.3．Where can the text be found?A．In a travel brochure.B．In a business newspaper.C．In a geography textbook.D．In a family magazine.While watching videos on Douyin one day, I discovered a very unique profile: an88-year-old farmer livestreaming (网络直播) trendy products in a rural setting. I clicked his page and saw that he was livestreaming because he needed to pay for his wife's medical expenses. Curious, I decided to contact him and learn more about his story.Now a retired farmer, Wu relies on government allowance. One rainy day, he returned to his shabby one-floor cottage in the suburb of Henan Province and found his wife lying on the ground in great pain. She had broken her leg and lost the ability to walk.A great burden befell this already disadvantaged family. The medical expenses for Wu's wife are about 800 yuan per month. Her daughter, a mother of three and a housewife, has no means of supporting Wu financially. As a heavy user on Douyin, Wu's daughter thought that perhaps they too could try livestreaming as a way to help their family. With a 9. 9 yuan phone holder, they began livestreaming on Douyin, and Wu became one of the oldest livestreamers on the platform.Every day, Wu livestreams for a total of six hours, separated into morning and afternoon sessions. With a broad smile and comforting voice, he explains the products on his table, which range from water bottles, makeup removers and vegetables to traditional Chinese clothing that Wu wears himself in front of the camera. Thousands of viewers are drawn in by his moving story and kindly personality. They refer to him affectionately as “my uncle Wu” or “Laoxiang”.During my interview with him, Wu would laugh warmly. His strong Henan dialect was sometimes hard to understand, but his tone was full of comfort and optimism.He also does not avoid showing affection for his wife, “I will buy her good food when I have the money.” I am moved by his ability to see the optimistic side of life despite being influenced by hardships and his persistence sailing through the low tides of life.4．Wu's videos are intended to _________.A．show love to his pitiful wifeB．advertise the beautiful countrysideC．make money by promoting various productsD．help the poor by drawing public attention5．What can we know about Wu's family?A．His daughter manages to offer financial assistance.B．They have got out of poverty by livestreaming.C．His daughter is a professional Douyin livestreamer.D．They have difficulty in covering the medical expenses.6．What attracts viewers to Wu's livestream?A．His rich experience on the platform.B．His amusing Henan accent.C．His good nature and touching story.D．His successful marketing techniques. 7．Which can be a suitable title for the text?A．An elderly farmer livestreamer B．A kindly and helpful husbandC．A popular application D．A way to cope with povertyAndroid phones will be used to sense earthquakes around the world and may one day be able to provide global warnings, with the first mass alert system coming into use on August 11 in California, Google announced.Google, which helped develop Android, worked with California and the US Geological Survey to build the quake alerts into all phones that run the common mobile operating system. Android users who have enabled location services and are near a quake of magnitude 4.5 or greater will receive a full-screen earthquake warming telling them to drop to the floor and seek cover. The screen also will provide estimates of the quake's magnitude and distance from the user. Depending on their distance from a quake, people could get several seconds or perhaps a minute of warning.Users won't need to download California's MyShake app in order to receive the alerts. That application, developed by the University of California, Berkeley and launched last year, has been downloaded by only about 1 million of California's 40 million residents. By contrast, many millions of people own Android phones.“This announcement means that California's world-class earthquake early warning system will be a standard function on every Android phone—giving millions precious seconds to drop, cover and hold on when the big one hits,” Gov. Gavin Newsom said in a statement. IPhone users won't receive the alerts through Apple's operating system, but theycan download the MyShake app.Also, Google announced that Android phones would begin detecting earthquakes from around the world through their motion-sensing accelerometers. “Your Android phone can be a mini-seismometer (地震仪), joining millions of other Android phones out there to form the world’s largest earthquake detection network,” according to a Google blog post. More than 2 billion devices run the Android operating system. Hundreds of millions of people live in earthquake-prone areas. But many countries lack the resources to build detection and alert systems, Google said. The information will be used at first to provide fast and accurate information on Google Search. But Google said it could begin sending out earthquake alerts next year.8．If an earthquake hits the US, who won't receive the earthquake warning?A．Android users who haven't downloaded the MyShake app.B．IPhone users who have downloaded the MyShake app.C．IPhone users who haven't downloaded the MyShake app.D．Android users who have downloaded the MyShake app.9．What can we learn from the text?A．Millions of people have downloaded the MyShake app.B．The earthquake early warning system will be of great help.C．Google has already sent out earthquake alerts since last year.D．Over 2 billion devices run the Apple operating system.10．What will globalize Google's earthquake detection network?A．New technology developed by Google.B．The large number of Android phone users.C．Motion-sensing accelerometers.D．The newly developed MyShake app.11．What is the author's purpose in writing the text?A．To share a new MyShake app.B．To promote Android phones.C．To make Google known to the world.D．To introduce a new function of Android phones.While the increase in the number of unemployed Americans has been a focus ofeconomists throughout the pandemic, another problem has been mostly overlooked: The people that do have jobs are calling out sick in record numbers.Unlike the jobless rate, which has declined noticeably, the rate of absenteeism (旷工) has remained stubbornly high. More than 1.9 million people missed work in December, according to Labor Department data. Michael Gapen, chief US economist, says although vaccinations could start driving down absenteeism, the missed work is causing supply chain problems. “Absenteeism could lead to shortages; it could lead to higher prices and more limited output,” he says.The problem is so acute that companies are lobbying local authorities to get their workers near the front of the line for vaccinations. “There are instances of having to shut down lines at various points in time in order to manage the absenteeism,” says Geoff Freeman, a chief executive officer.According to the Institute for Supply Management, factory activities increased in December, with the employment returning to a level that indicates growth. However, one complaint is that suppliers are still struggling with their own employee shortages, which is causing supply problems. “The quantity of infections and the quantity of people who are sick or having to self-quarantine (自我隔离) are just so overwhelming that everybody has to be affected by it,” Timothy Fiore, said on a Jan. 5 call with reporters.For office workers, 90% of professionals said before the pandemic they'd sometimes go to work sick. COVID-19, however, contributes to the fact that more employees are staying home to protect themselves and others.“We know when the absenteeism will end, and that's when we get the vaccine in people's arms,” says a manager. But a lack of federal leadership means “this is the Wild West right now, and we see the results of that.”12．What does paragraph 2 mainly tell us about absenteeism?A．Its root causes.B．Its major consequences.C．Its future development.D．Its economic values.13．Which of the following is closest in meaning to the underlined word “lobbying” in paragraph 3?A．Persuading.B．Cheating.C．Informing.D．Predicting.14．What can we say about America’s absent workers?A．They complain about their working conditions.B．They call out sick because of their mental pressure.C．They struggle with the supply shortages.D．They are largely impacted by the pandemic.15．What can be inferred from the text?A．There are more jobless workers than the absent ones.B．Supply chain problems are causing absenteeism.C．All people aren’t satisfied with the federal government.D．Workers won’t return to work even if they are vaccinated.二、七选五Easy ways to improve your work productivity___16___.Take breaks outsideGetting outside to stretch your legs can boost your mood and help you to disconnect from your work for a bit. ___17___.

But is "boredom" senseless? My friend Renee, who has driven cross-country with her three kids eight times, calls boredom the mother of creativity. She's not the only one who sees virtue in blank time. In a recently published paper, researchers at East Anglia University in England concluded that the trancelike（发呆的） state helps recharge the mind and is "central to learning and creativity". I wasn't trying to make my kids smarter. Neither do I dislike high-tech, but I understand too well the power of mini screens to transform our kids into zombies （木讷的人）.On Day 1, our 7-year-old son announced "Texas is so boring!". The next day, struggling against his seat belt, he yelled he couldn't take much more of this. His 5-year old sister was better at the long hours playing make-believe with the stuffed animals. On Day 3 he began to count mountains and see pandas anddolphins in distant clouds in the Texas sky. I often joined the kids in the back, where we did thumb-and-toe wrestle. With well-known mountains ahead, my husband told the children the past legends of them. "Arizona is not as boring as Texas, " our son declared.I hope the trip gave kids some lazy, unstructured time to learn something about valuing the trip instead of looking for TAL#NBSP the fastest way to burn it up. I don't always make the right call as a parent but I know that in banning the small screen we made the right choice this time.(1) Why did the author choose a high-tech free journey?A. Her friends are highly against it.B. She disliked advanced technology.C. She feared the passive influence of mini-screens.D. The researchers proved the harm of modern technology.(2) What happened during the cross-country drive?A. Their son got worse at boredom.B. Her kids had a tough time riding in the vehicle.C. Their son relieved himself by watching animals outside.D. The time spent without screens strengthened the family bond.(3) The underlined part "the fastest way" in the last paragraph refers to.A. the speediest route to finish the journeyB. the ability to observe the surroundingsC. the interest of playing games with othersD. the choice of killing time by playing digital devices(4) Which is the best title for the text?A. Is Driving Long Distances Good for Children?B. A Touching Cross-country Trip of My FamilyC. What's Wrong with Boredom without High-tech?D.

But new guidelines from the American Academy of Neurology suggest there's something better you can do to keep your mind sharp.A quarter of adults aged 80 to 84 experience mild cognitive（认知的）TAL#NBSP impairment, according to AAN. To address the widespread problem, a group of neurologists and Alzheimer'（阿尔兹海默氏症的） specialists went through existing studies to define the best ways to prevent and treat cognitive decline—and you might be surprised by what they included and what they didn't.Surprisingly, the AAN guidelines don't include any medication（药物） or dietary recommendations. The authors stress that there haven't been any high quality, long term studies finding foods or medication can help cognitive decline. The guidelines also say doctors can consider suggesting cognitive training to patients with memory loss but not to rely on it. So far, the report authors say the evidence is too inconclusive to say for sure if brain exercises, like memory and attention training or problem-solving for everyday issues associated with memory loss, are beneficial. Still, these morning brain exercises can't do any harm.But there was one big discovery from the new guidelines: Exercising just twice a week could improve cognitive decline. One study showed adults with mild cognitive impairment who did resistance training twice a week scored better on executive function and associative（联想的） memory tests than a group that worked on balancing stretching, and relaxing.What's more, another study had older adults attend either biweekly health classes or sessions of aerobics, strength training, balance exercises, and multitasking training. Six months later, the ones who'd exercised regularly scored better on cognitive health and memory tests, plus had less brain shrinkage.AAN now recommends doctors tell patients with memory loss to exercise twice a week to keep their minds sharp. This is the best time to exercise if you want to improve your memory. It looks like you've got just one more reason to clear time in your schedule for a workout—even if it's only on the weekends.(1) What does the underlined word "impairment" in paragraph 2 refer to?A. Error.B. Decline.C. Development.D. Presence.(2) ANN may be uncertain about.A. strength trainingB. resistance trainingC. exercises twice a weekD. morning brain exercise(3) Which of the following may the author agree with?A. Daily exercises are beneficial to Alzheimer.B. The AAN guidelines attach importance to workout.C. Medication is of significance in the ANN guidelines.D. Stocking up on vitamins supporting brainpower means nothing.(4) In which section of a newspaper may this text appear?A. Exercise.B. Entertainment.C. Science.D. Health.4、【来源】 2020年辽宁沈阳皇姑区辽宁省实验中学高三一模（D篇）第32~35题8分2020年黑龙江哈尔滨南岗区哈尔滨师范大学附属中学高三一模（D篇）第32~35题8分Clothing rental is a hot new industry and retailers（零售商） are demanding to get on board in hopes of attracting green shoppers.But is renting fashion actually more environmentally friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline investigated（调查） this question and concluded that it's not as sustainable as it seems.Take shipping. For example, which has to go two ways if an item is rented—receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.She writes, "An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased from a physical store and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's."Then there's the burden of washing, which has to happen for every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry cleaning, a high-impact andpolluting process. All the rental services that Cline looked into have replaced perchloroethylene（氯乙烯）, a carcinogenic（致癌的） air pollutant, still used by 70 percent of US dry cleaners, with alternatives, although these aren't great either.Lastly, Cline fears that rental services will increase our appetite for fashion, simply because it's so easily accessible. There's something called "share-washing" that makes people waste more precisely because a product or service is shared and thus is regarded as more eco-friendly. Uber is one example of this, advertised as "a way to share rides and limit car ownership, " and yet "it has been proven to discourage walking, bicycling, and public transportation use."Renting clothes is still preferable to buying them cheap and throwing them in the dustbin after a few wears, but we shouldn't let the availability of these services make us too satisfied. There's an even better step—that's wearing what is already in the closet.(1) What is Elizabeth Cline's attitude toward clothing rental?A. Approving.B. Unfavorable.C. Objective.D. Enthusiastic.(2) The Uber example in Paragraph 6 indicates that.A. rental services are on the riseB. clothing rental will be as successful as UberC. renting clothes might waste more than expectedD. renting clothes might make people lose interest in fast fashion(3) The author suggests that we should.A. give up renting any clothingB. purchase inexpensive clothesC. rent clothes rather than buy themD. make full use of clothes we've possessed(4) What is the passage mainly about?A. Clothing rental is a new fashion.B. Clothing rental is retailers' preference.C. Renting clothes is not that eco-friendly.D. Renting clothes business is in a dilemma.二、七选五（本大题共5小题，每小题2分，共10分）5、【来源】 2020年辽宁沈阳皇姑区辽宁省实验中学高三一模第36~40题10分2020年黑龙江哈尔滨南岗区哈尔滨师范大学附属中学高三一模第36~40题10分Last year in a cross-country race in Sanqing Mountain, Gentian left everybody far behind, but unexpectedly he felt a sharp pain and saw that there were teeth marks and blood on his calf（腿肚子）.1But he didn't know that it was a poisonous snake called "five-step snake" in Chinese that bit him.Deep in the mountain, with no phone, Gentian kept running with the injury on his leg for 15 minutes and finally met a local farmer.2He happened to know about herbs and medicine. Immediately, he used some herbal medicine to deal with it, Later, the organizing committee's ambulance rushed to take him to the local hospital.What should you do if you encounter a snake while outside? Remember: first of all, do not excite it. Data show that people who excite snakes are easily bitten.3Second, avoid the places where snakes like to stay. Snakes like to bathe in the sun during the day, and usually stay on gravel and cliff edges. Third, if you happen to see a snake crossing through the road, you must stop and wait for it to pass.4First, sit down and try to avoid the acceleration of blood circulation. Then tie the limb 10-30 cm above the wound with a strong rope, and cut it open about 1 cm above the wound. The cut should be 1-2 cm wide, and squeeze blood from top to bottom. Generally, snake bites occur at the ankle.5Also, make sure to call the ambulance ASAP.A. He sensed that his situation was not good.B. Then what to do if you're bitten by a snake?C. So staying still can prevent you from meeting a snake.D. He thought his high end shoes could protect against the snake.E. However, those who run immediately are less likely to be bitten.F. In this case bending the knee to reduce blood flow can be helpful.G. Despite the language barrier, he understood what had happened.三、完形填空（本大题共20小题，每小题1.5分，共30分）6、【来源】 2020年辽宁沈阳皇姑区辽宁省实验中学高三一模第41~60题30分2020年黑龙江哈尔滨南岗区哈尔滨师范大学附属中学高三一模第41~60题30分At around 6:30 pm local time on April 15th in France, Notre Dame in Paris was getting angry.

生于斯，长于斯，你对中华文化怎样认知?文化学者余秋雨认为华夏文明是世界上最长寿的文明，对比希腊、巴比伦等其他文明，只有华夏文明从未出现过历史断层与空白，以殷商甲骨文为代表的古文字体系一脉相承到今天。

他说“中国文化有特殊生命力”，“不管到哪一代，中华文化，总在”。

英国学者罗素于1920年来到北京大学做了两年的客座教授，他预言中国人会在很短的时间内掀起一场极端暴力的革命，然后认识到暴力不能带来和平幸福，进而结合儒家思想和西方文明的优点，重新创造出人类历史上另外一次很伟大的文明。

从以下任务中任选一个，以“振华中学”青年学子的身份完成写作。

（1）写一篇演讲稿，向来你校参观的外国中学生介绍中华文化的特殊生命力。

（2）写一份倡议书，向全校师生发出继承与发扬中华优秀传统文化的倡议。

（3）写一封信，向某位政要或长者讲述你对“结合东西方优点、创造伟大新文明”的建议与思考。

要求：结合材料，自选角度，确定立意；切合身份，贴合情境；符合文体特征；不要套作，不得抄袭；不得泄露个人信息；不少于800字。

【试题来源】东北三省三校（哈师大附中、东北师大附中、辽宁省实验中学）2020届高三第一次联合模拟考试语文试题【答案解析】例文：兼收并蓄，振兴中华xxx阁下：展信佳！请原谅一位有思想的青年贸然打扰您。

我是振华中学的一名学生，请您考虑并接受“结合东西方的优点，创造伟大新文明“的建议。

我认为，只有“兼收并蓄”，融中通外，才能“振兴中华”。

希望这一美好构想，能在各位支持下变成现实，让民族复兴大业早日实现。

保留传统文化，互鉴西方文明。

以儒家思想为代表的中华传统文化固然伟大，但在新时代背景下，有些东西不能适应时代发展。

学习和借鉴外国文化，包括西方先进文化，对于我们各项事业的发展，大有裨益。

改革开放四十年，中国之所以发展迅速，除了中国人民自力更生，。
