AAt age 12,Keegan Sobilo of New Baltimore carefully tucks his legs and arms into a fire suit, pulls on a helmet and climbs into a race car that exceeds 80 mph. He has been doing this since age 8.“ At first, I was scared to death. I was like, 'Let's do bowling or swimming. ' It's still very scary. But he knows what he's doing. Your heart goes out on that track every time he goes out there," said his mother Hillary Sobilo.＂The sixth-grader always wears pajamas to the track every night and takes them off when he puts his race clothes on. He's been doing that for the last four years. That's his trademark,” said Tim Phillips, his crew chief. The first time he wore his train pajamas to the track, Keegan went from last place to ninth place. He decided they brought luck. Since then, he has won a series of championships.Passion for cars runs in the family. Keegan's father is a design mechanic at Fiat Chrysler Automobiles. He knows what it means to have seats and roll cages built to fit his son's body. "What I see in Keegan is passion, like how I feel about car restoration. But for him, everything has to align itself. I tell my son you have to be the perfect package. Winning races every weekend is not the only key. More importantly, you have to have the right name, you have to look the correct way, speak the correct way, and act the correct way. Then the rest of it is really luck, like the stock market. If you don't put yourself out there, you'll never hit it big."While Keegan's classmates play basketball and volleyball, Keegan is at the Birch Run track-practicing, qualifying and racing until 10 p.m. or 2 a.m. While many children spend time playing video games, Keegan runs race simulation training with his joystick after school.＂The kid is cool. It was like having a grandson. We showed respect to each other. And he takes it very seriously," said competitor Mike Todd,69,of Galesburg, Michigan. "He's an older soul in a young man's body. I'd like to see him make it big. He's got the willpower."21. Keegan enjoys ______A. swimmingB. racing carsC. bowlingD. playing games22. According to the passage., what does Keegan's father value most?A. Victory.B. Safety.C. Good qualities.D. Real luck.23.It can be learned from the passage thatA. Keegan spends a lot of time practicingB. the train pajamas bring Keegan successC.Keegan's mother worries about his studiesD. Keegan picked up the hobby at the age of 4BYou're never too young to make an impact on your community.Members of Gen Z are exceptionally creative, cause-oriented, and hyper-aware of the world around them, making them perfectly ready to help handle the world's problems through volunteering.If you want to make a difference in your community, be a part of something bigger than yourself, or just need to earn some required volunteer hours, then this is the place to start.

2020届北京市海淀国际学校高三英语上学期期中考试试题及答案解析
2020届北京市海淀国际学校高三英语上学期期中考试试题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AChildren under the age of 18 will be allowed up to three hours per week to play video games, according to a notice issued by China's National Press and Publication Administration. Online game companies are required to provide services to minors — from8 to 9 p. m. on Fridays, Saturdays, Sundays and legal holidays — as a way to safeguard their physical and mental health. Children are playing more and more online games these days. Is it time to limit their online gaming time? What role do parents have? Readers share their opinions.RizlaredOnline games are addictive, but if children are taught how to manage in a sensible and responsible manner then it is no longer a threat(威胁).To achieve this, parents need to set examples for not being glued to their phones. Teaching is and always will be the best solution to such problems.AndrewGood policy. By limiting time spent on online games, kids can spend time doing more useful things to develop their potential. They can go outside and run, jump and swim instead of sitting on a couch at home and playing with a smart phone.AdamIt is often seen that parents argue with children over cellphones. Most parents can hardly set and enforce the time limit for its daily usage. Some forcibly take away their cellphones, but it will ruin trust and relationship. Even worse, it will make their kids hate them.PinkExcessive(过度的）gaming is purely a waste of time and energy for minors and has a negative effect on both physical and mental health. The gaming industry should not put profit- flaking interests as its priority (优先事项) . They should act in a socially responsible way toprovide an environment for children to ensure their well-being and development.LaurenThere would be a loophole(漏洞). Children could use their parents’ or other adults’ IDs to avoid real-name registration, thus making it impossible to put this policy in effect. Parents ly need to strengthen guidance andsupervision to keep their children from gaming addiction.1. What should kids do according to Andrew?A. Play online games.B. Play with a smart phone.C. Study all the time.D. Go in for outside activities.2. What does Pink advise the gaming industry to do?A. Pay attention to its profit.B. Focus on kids’ health.C. Be responsible for kids’ surroundings.D. Persuade kids lo play more games.3. What role do parents have according to the passage?A. They keep hold of their phones.B. They set examples for their kids.C. They limit their kids’ time.D. They blame kids for addiction.BMany of us in China enjoy adding chilies (辣椒) toour food, but did you know that this spicy vegetable could also be dangerous? A 34-year-oldUSman recently ended up in hospital after eating a Carolina Reaper—the spiciest chili in the world. After taking just a single bite of one, the man suffered from serious headaches in the following few days, reported BBC News.In fact, reports of stomachache and headache caused by eating spicy food are not something unusual. But if chilies are harmful, why is it that human beings are the only animals to eat this vegetable? According to the website Huanqiu, about 600 million Chinese people—almost half of the national population—are chili eaters. So what makes people love chilies so much? The human body reacts to the burning feeling that comes from eating chilies by releasing natural chemicals that “produce a sense of happiness” , noted BBC News.And the benefits go even further than just personal enjoyment. A survey conducted by the Chinese Academy of Medical Sciences found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week. The number decreased to 14 percent for those who eat spicy food six to seven times a week. And another study done by theUniversityofVermontcame to a similar conclusion. “The data encourages people to eat more spicy food to improve health and reduce death risk at an early age,” Liu Qi, a nutritionist at the Harvard TH Chan School of Public Health, told BBC News.Chilies have anti-cancer quality and the ability to increase our metabolism (新陈代谢). So, don't worry if you love spicy food. It seems that chilies are actually good for us—except for the Carolina Reaper, perhaps.4. The example of a 34-year-old American is mentioned in Paragraph 1 to prove ________.A. chiliescan be beneficialB. chilies are popular inAmericaC. chilies can be dangerousD. serious headaches can be dangerous5. Eating chilies gives people a sense of happiness by_______.A. decreasing death rateB. releasing natural chemicalsC. curing serious headachesD. providing enough nutrition6.

The more chilies you eat, the healthier you are.D. Chilies have anti-cancer quality but it can't increase our metabolism.7. The writer wrote the passage to ________.A. warn people of the dangers of chiliesB. ask people to eat Carolina ReaperC. encourage people to eat more chiliesD. tell people the benefits of chiliesCAccording to a survey, the wasteof food on the dining table occupies 10% of the total grain output.Last week, Meituan, a giant online food ordering platform, co-published a proposal with a number of business organizations, calling on restaurants to stop food waste and help develop new eating habits for customers. Following the proposal, merchants are asked to offer guidance for consumers, including reminding them during the ordering process about the taste of the ingredients, portion sizes and other information about the dishes, to helpthem avoid excessive ordering and food waste.Catering（餐饮)associations in more than 18 provinces have also joined the campaign to remove food waste. The Wuhan Catering Association proposed an “NT" ordering code for restaurants in which a group of 10 diners would only order enough for nine people. More food is only brought to the table if required. On Friday, the China Cuisine Association announced that it had teamed up with Ele. me, the Alibaba Group Holding-owned food delivery platform, to launch a "half-dish plan," encouraging restaurants to provide customers with the option to order smaller portions.Tang Zhisong, a professor at Southwest University Education School, said "Evaluating how much you can eat, how much you should buy and how to deal with the leftover is a way for young people to improve their self-management. It's also a means to teach them sharing food, caring about others, and more importantly, developing a mindset of suitability. "8. What's the purpose of the proposal mentioned in the passage?A. To change customers' attitude toward life.B. To promote a new policy on food delivery.C. To spread the idea of healthy eating.D. To encourage restaurants to reduce food waste.9. What does the underlined word “excessive" in Paragraph 2 prolably mean?A. More than enough.B. Less than required.C. Better than ever.D. Worse than before.10.

After getting married, she spent 18 years staying home with her children. She held several jobs through her life, including 20 years as a secretary at a hospital until her retirement at age 77.Fein has had a full life.

2020届北京市海淀实验中学高三英语上学期期中考试试题及参考答案
2020届北京市海淀实验中学高三英语上学期期中考试试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AWhile Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.Using a web camera equipped in Jennifer'sLos Angelesapartment, the monitor inPhoenixtracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked remotely to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past？Or was she slowing down？In the battle against cheating, this is thecutting edgeand a key to encourage honesty in the booming field of online education. This technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven't searched the Internet to get the right answers.Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses". Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone numbers they once used.Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.1. Why was Jennifer watched in an online exam?A. To correct her typing mistakes.B. To find her secrets in the room.C. To keep her from dishonest deeds.D. To prevent her from slowing down.2. What does the underlined expression "cutting edge" in Paragraph 3 probably mean?A. sharpening toolB. advanced techniqueC. effective ruleD. dividing line3. How can some programs find out possiblecheaters?A. By scanning the Internet test questions.B. By checking the question answering speed.C. By producing a large number of questions.D. By giving difficult test questions.BHundreds of children are being treated for sleep problems in Wales every year. In some cases，babies，infants (婴儿)and teenagers have been admitted to hospital in north Wales alone.The Children’s Sleep Charity said many children were suffering from lack of sleep mainly because of technology use. Public Health Wales said sleep was as important to a child’s health as healthy eating and exercise，and children with poor sleep patterns were more likely to be fat.Statistics obtained (获得) under the Freedom of Information Act by BBC Wales found at least 408 children have been admitted to hospitals across Wales suffering from sleep disorders since March 2013.Children aged between 0 and 4 made up the highest number of inpatients (住院病人)，with some newborns being treated for sleep-related problems from the day of birth.Vicki Dawson，who set up the Children’s Sleep Charity (CSC)，said sleepless nights were putting both children and parents in anxiety. “Their weight and growth may also be affected as well as their mental health，”she said.Teachers said children showing signs of sleep shortage and tiredness in class were a concern as they couldn’t concentrate for long periods.Psychologist Amy McClelland，of Sleep Wales，saida common problem was that children were “over excited”before bed and that families should get back to basics. “Think 1950s family home. Dinner as a family，read，chat，a film maybe，lights off and then bed. ”She added.4. What’s the mainreason why children are short of sleep？A. Less exercise.B. Eating habits.C. Technology use.D.

Chatting and films make children sleep more.B. It is difficult for children to read before bed.C. Being too excitedis good for sleep habits.D. Relaxation has a bad effect on children.7. What is the best title forthe text？A. Ways to Treat Sleep ProblemsB. Sleep Problems of Welsh ChildrenC. Sleep Habits of Welsh ChildrenD. The Problems of Welsh ChildrenCHaley Curfman, 25, of Blackwell, Oklahoma, is a teacher at Blackwell Public School and last yearshe bought a plain(朴素的) white dress, which she set up a station in her classroom for her students to decorate, encouraging them to go and draw on the dress whenever they had free time. Haley set up a station at a table with the dress and some color1 ed markers so that her students could draw on it, having first seen the idea on Pinterest.After the kids had finished the design, she then surprised them all by wearing the dress to class, sharing pictures of herself in it on Facebook in a post that has since been shared over 200, 000 times.For teachers looking to do something similar for their own students, Haley said that she bought the dress off Amazon for less than $ 20 about six months ago and pre-washed the dress before she started the project. She used markers from Walmart. But she said these things can be bought in other places. She said, “To do the project, I set up a station at a table with the dress and markers. It takes anywhere from two weeks to a month to complete as we just work on it here and there when time allows. You'd better give the students enough time so they don't have to hurry.”“Teachers have been sharing their dresses, T-shirts, etc. with me that they've been creating since the 1950s with the same idea. It is amazing, and I love the fact that you are sharing them with me! Thank you all so much for your kindness and support,” she wrote on Facebook.Asked why she came up with the idea, Haley told Scary Mommy. “We don't have art in our school, so, I always try to do little creative projects when possible.”8. What did Haley use the plain white dress to do?A. To teach her students painting.B. To prepare for her presentation.C. To ask her students to draw on it.D. To help her students with their homework.9.

To exciteher students' creativity.DFlying someone one-way fromLondontoNew Yorkproduces nearly a ton ofcarbon dioxide or CO2. That's alot of this climate-warming greenhouse gas. But there are ways to cut the climate impact of flying, one of which is to ask planes to surf high-altitude winds every chance they get.It's not something they've been allowed to do. But that may change—and soon.Most jets crossing the Atlantic Ocean follow one of several fixed paths that are widely spaced because radar (雷达) had not been able to track aircraft everywhere above the Atlantic. But a new network of satellites could soon change that.Wells was part of a team inEnglandthat calculated the fastest possible routes for passenger planes. According to them , traveltime a plane takes when flying across theAtlanticvaries with the winds that a plane meets. For instance, eastbound (向东的) flights can get a powerful push. Westbound routes miss that benefit. Faster flights burn less fuel. And less burning gives off fewergreenhouse gases.The airline industry knows it has a high " carbon footprint." But it takes decades and many billions of dollars to design, test and fly new planes. Changing a flight path, in contrast, can cut costs and energy right away.The new study doesn't show how well such wind surfing would work for all planes, in all skies and the world over. Bui it does suggest that making flight routes more flexible could cut both fuel use and CO2in some places.However, if flight times vary depending on the wind, scheduling connecting flights and managing runways and gates would become more complicated. The researchers would have to work out the best flight paths thattake such scheduling issues into consideration. They may also want to see if flying at different altitudes gives a wider choice of flexible routes at the times most people want to fly.National Air Traffic Services (NATS) which provides air-traffic control for theUnited Kingdomsaid it would temporarily disband its flight-paths system and work to allow airlines to choose flexible routes that would best limit their fuel use.12. What happens to east bound flights when crossing theAtlantic?A. They consume more fuel.B. They use less time and energy.C. They produce more greenhouse gases.D. They are against a stronger wind.13. What should be done to make adopting flexible flight routes possible?A. Calculating the flight time.B. Finding the best flight paths.C. Adjusting the size of jets.D. Adding more runways and gates.14. Which word can best replace the underlined word "disband” in the last paragraph?A. Stop.B. Copy.C. Handle.D. Restore.15. What can we infer from the text?A. Planes are producing the most carbon dioxide.B. New fuel is benefiting airline industries greatly.C. Carbon footprint is a serious problem in theUK.D. Surfing the winds can make air travel greener.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。
2020届北京市海淀国际学校高三英语上学期期中考试试卷及参考答案
2020届北京市海淀国际学校高三英语上学期期中考试试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ALocated besideLake Geneva, the Olympic Museum houses more than 10,000 artificial objects and hours of interactive contents highlighting some of the best moments during the Olympics. Here are some of the museum’s most moving moments.The Olympic ParkThe journey through the Olympic Museum begins in the Olympic Park, an 8,000-square-meter outdoor area in front of the museum overlooking Lake Geneva and theAlps. The park contains artwork and sculptures that show respect to the world of sport.The first Olympic SymbolThe “Olympic Rings” flag was designed by Coubertin in 1913. The rings represent the five continents that participate in the Olympics: Africa, Asia,America,AustraliaandEurope. The six color1 s include at least one color1 that is represented on the flag of every country.The StadiumsThe stadiums that host the Olympic Games are as much of a celebration of design as the games are a celebration of sportsmanship. Guests can explore plans and models of Olympic stadiums’ past and present, including one of the games’ most attractive stadiums, the Bird’s Nest from Beijing 2008 Olympics.The Olympic MedalsHave you ever wondered what an Olympic medal looks like? The Olympic Museum has a room that houses every bronze, silver, and gold medal from every Olympic Games dating back to the first modern Olympics of 1896. Each medal design is a unique representation of the year and location in which the games were held.1.Which moment do you see first when exploring the Olympic Museum?A.The Olympic Park.B.The first Olympic Symbol.C.The Stadiums.D.The Olympic Medals.2.What can you do in the section of The Stadiums?A.Celebrate the glory of a sportsman.B.Meet the designers of the stadiums.C.Explore the future stadiums.D.Enjoy the model of the Bird’s Nest.3.In which column of a newspaper may this text appear?A.Entertainment.B.Science.C.Travel.D.Business.BA new study finds almost one third of the world’s population is overweight. Since 1980, obesity rates(肥胖率)in children and adults have doubled in 73 countries, making people more worried. And rates are increasing in many other countries. Obesity is increasing faster in children than adults in many nations, including Algeria, Turkey and Jordan, the report said. But the world's weight problem is growing in both rich and poor countries alike. Researchers say an increasing number of people are dying of related health problems in what they called a "disturbing global public health problem."Researchers studied health information from 1980 through 2015. They examined obesity rates, average weight gain in 195 countries. They found that obesity rates are three times greater among youth and young adults in countries like China, Brazil and India. Almost 108 million children and more than 600 million adults were found to be overweight. Egypt had the highest number of overweight adults in 2015. Vietnam had the least. In the same year, the United States had the highest number of overweight children, and Bangladesh had the least.Yet hunger remains a problem in many areas. The United Nations said that almost 800 million people, including 300 million children, go to bed hungry each night. Experts said poor diets and lack of physical activity are mainly to blame for the rising numbers of overweight people.Growing populations have led to rising obesity rates in poor countries. Often, poor people will eat processed(加工的) foods instead of choosing a diet rich in vegetables.The London-based Overseas Development Institute studied the price of food in five countries: Britain, Brazil, China, Mexico and South Korea. It found that the cost of processed foods like ice creamand hamburgers has fallen since 1990. But the cost of fresh fruits and vegetables has gone up.4. What do we know about obesity in the world?A. It is worryingB. It is given no attentionC. It has been successfully solvedD. It is more serious among old people5. Which country has the most overweight children in 2015?A. AmericaB. VietnamC. EgyptD. Bangladesh6. What is one of the reasons why people get overweight?A. HungerB. Poor dietC. Diets with vegetablesD. Eating too much fruit7. Which ofthe following can be the best title for the text?A. It’s Important to Have a Balanced DietB. How Can We Lose Weight and Keep Fit?C. Is It Necessary for Us to Eat Fresh Vegetables?D. Nearly One Third of People in the World Are Overweight.CIn someareas ofCalifornia, it’s so dry that farmers aren’t willing to plant crops this season. Growers, north ofSan Francisco, have begun pulling out of local farmers markets.CountyLineHarvest, which farms more than 30 acres inPetaluma, hasn’t had enough water to grow all the peppers, lettuces and other produce for a long time, according to a video on its Instagram page. Nearby farms arc saying the same, emphasizing (强调) the effect of theextendeddry periods.Californiagrows a third of theUnited States' vegetables and two-thirds of the nation's fruits and nuts. If dry weather prevents farmers from growing plants, that could lead to pushing up the price of food that's already starting to affect theU.S.economy.“Due to severe drought, for the first time in 21 years, we will not be able to grow this summer inPetaluma,"CountyLinesaid in its post.Drew Lerner, president of World Weather Inc. inKansas, saidCalifornia“missed the rainy season" and won't see much moisture (水分) over the next several months.A La Nina weather pattern in the Pacific pushed winter storms north and away from the state, leaving it with less moisture than usual. AsCaliforniagets most of its water from winter storms, little relief is expected before October.That has left growers such as Shao Shan Fann in a bind. The business can’t offer the selection of Asian vegetables and Bay Area staples it usually grows at its Bolinas location, according to its website.Nearby, Green Valley Community Farm has access to only about 5% of the water it usually relies on, owner David Plescia said. He’s looking for new land with enough water to use, and also has a permit in the works to grow cannabis to make up for the lost income. If it doesn’t make it, he’ll leave the fields empty.“It’s part of our generation’s cross to bear, figuring out how to run small — or medium-scale farm businesses in this kind of atmosphere of highly variable rainfall,” Andrew said.8. What does the underlined word “extended” in the second paragraph mean?A. Hot.B. Short.C. Long.D. Wonderful.9. Which is the result if the dry weather stops famers from planting crops?A. Theincreaseinthe priceof food.B. The growth of economy inU.S.C.Lessmoisture than usual.D. The low price of Asian vegetables.10. From what Andrew said, we can infer (推断) all of the following statements EXCEPT that________.A. The climate is not very goodB. It is part of the burden for people of his generationC. It is hard for him to run his farm businesses insuch bad climateD. He is sure that the serious drought will come to an end soon11. What does the passage mainly talk about?A. How do the famers run businesses inCalifornia.B. How does the owner look for new land with enough waterC. California farmers facing drought choose not to plant crops.D. The farm economy of theUnited Stateshas changed a lot.DI have a memory of being about five years old, picking up a beautiful grilled(烧烤的）cheese sandwich made for me by my hard —working mother and turning it over to see that theother side was burned. Suddenly what I thought was the perfect sandwich was not so perfect. Mom had tried to hide that fact from me. There was no question; I ate it anyway without complaining. However, that moment has stuck in my mind for many years. Now, at the age of 43 as a mother of two children and as a biology professor where I am routinely the "academic mother" of hundreds of students every year,I find that I believe inThe Grilled Cheese Principle.Here is what I mean Making a grilled cheese sandwich is easy right? But when I think of how many burned grilled cheese sandwiches I have eaten, or I have made myself, I realize that most of the grilled cheese sandwiches I have known have had at least one burned side. The thing is that although it is a ly easy thing to make, I can also easily lose focus, and before long the sandwich is burned. For my mother, the first side was usually perfect and the second side got burned due to her being distracted. For me,I have tended to burn the first side,but then I more carefully monitor the second side.Either way,the grilled cheese sandwich suffers because it has not been given theattention it deservesSo, I have learned that even the simplest task deserves my full attention. When I am multi-tasking, I am doing none of the tasks well. And when I allow myself to be distracted, I am not in the present moment — not paying attention to the small details of living or enjoying the processSo now, I believe the best way to make a perfect grilled cheese sandwich is to make only one at a time and give it my full attention.12. How did the writer react to the sandwich with burned side?A. She ate it with some complaintsB. She showed no interest.C. She thought it was still perfectD. She was deeply impressed with it13. What doesThe Grilled Cheese Principlemean?A. Even simple things deserve full attentionB. Losing focus makes the sandwich burnedC. Self-made sandwiches are always burnedD. we should make only one sandwich at a time14. Which of the following can we infer from the passage?A. Everything cannot be done well without full attentionB. Moms always like to lie to kids when they have done something wrongC. We can lose focus more easily when we do easy things.D. Multi-tasking can be an obstacle to the achievement of tasks.15. What does the writer mainly want to tell us?A. Nothing is perfectB. Learn to appreciate the burned sandwichesC. Devote yourself to one thing at a time.D. Never do multi-tasks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。

2020年北京市海淀国际学校高三英语上学期期中考试试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AElectric Shocks Can Be FatalGovernment statistics recently showed that in theUK, more than 3,000 people a year experience electric shocks in their homes. A smaller number of people are killed after they touch the power lines outside their homes. Electric shocks can cause a person's heart or breath to stop and are potentially fatal. It is essential for people to learn basic techniques to deal with such emergencies.What to do?● If you are the first person to reach someone who has an electric shock, don't touch him or her!● If the victim is still holding the appliance that gives him or her the shock (e.g. a hair dryer), unplug it or turn off the power at its source.Under no circumstances can you try to move the appliance with your hands!● Ifyou can't turn off the power, use a piece of wood, like a broom handle or a chair, to separate the victim from the appliance or the power source. You may even be able to do this with a folded newspaper.● The victim must remain lying down. If he or she isunconscious, the victim should be placed on his or her side. But he or she should not be moved if there is a possibility of neck or spine injuries unless it is ly necessary.● It is essential to maintain the victim's body heat, so make sure you cover him or her with a blanket before you do anything else. If the victim is not breathing, apply mouth-to-mouth resuscitation (人工呼吸). Keep the victim's head low until professional help arrives.● If the electric shock has been caused by an external power line, the dangers to the victim and to anybody providing first aid are much greater.1. What kind of passage is it?A. An advertisement.B. A horror story.C. A news report.D. First aid emergency advice.2. The underlined sentence implies that ________.A. you should move the applianceB. you should pick up the appliance and turn off the electricityC. it is very dangerous to touch the appliance with your handsD. it is unnecessary to unplug the appliance with your hands3. When a person has got an electric shock, you should ________.A. separate the victim from the appliance and let him sit upB. keep the victim warm and help him or her breathe againC. move the victim onto his or her side if he or she has got neck injuriesD. keep the victim's head high until professional help arrivesBThe modern Olympics, which appeared in ancient Greece as many as 3,000 years ago, have become the world’s most important sporting competition. From the 8th century B. C. to the 4th century A. D., the the ancient Olympics were held every four years in Olympia in honor of the god Zeus. The first modern Olympics took place in1896 inAthens, and featured 280 participants from 13 nations, competing in 43 events. Since 1994, the Summer and Winter Olympic Games have been held separately every two years. The 2020 Summer Olympics, delayed one year because of the COVID-19, was held in Japan in 2021.The ancient Olympics were held every four years between August 6 and September 19 during a festival honoring Zeus. The Games were named for their location (位置) at Olympia, a place near the western coast in southern Greece. Their influence was so great that ancient historians began to measure time by the Olympic Games held every four years.After the Roman Empire conquered (征服) Greece in the mid-2nd century B.C., the Games continued, but their standards and quality dropped. For example from 67 A. D., the Emperor Nero entered an Olympic horse race, announcing himself the winner even after he fell off hishorse during the event. In 393 A. D., Emperor TheodosiusⅠended the ancient Olympic tradition.It was another 1,500 years before the Games rose again, largely thanks to the efforts of Baron Pierre de Coubertin (1863-1937) of France. Working hard at the development of physical education, the young man became inspired by the idea of creating a modern Olympic Games after visiting the ancient Olympic building. In November 1892, at a meeting of the Union des Sports Athlétiques in Paris, Coubertin suggested the idea of making the Olympics an international athletic competition held every four years. Two years later, he got the approval (批准) he needed to found the International Olympic Committee ( IOC ), which would become the governing body of the modern Olympic Games.4. What do we know about the modern Olympics?A. The modern Olympics became famous in the 18th century.B. The first Winter Olympics was held in 1994.C. The first modern Olympics dates back to 1896.D. The latest Winter Olympics will delay for two years.5. How often were the ancient Olympics held?A. Every year.B. Every other year.C. Every three years.D. Every four years.6. When did the ancient Olympics end?A. In 393 A. D.B. In 67 A. D.C. In the mid-2nd century B. C.D. About 1,500 years ago.7. What is the best title of the text?A. The ancient OlympicsB. The modern OlympicsC. The Olympics developed through yearsD. The Olympics are popular in modern timeCIt was the first day of spring here but it didn't feel like it. The COVID-19 epidemic (流行病) was sweeping the globe and everywhere there were feelings of fear and loneliness. “Social Distancing” had become the new norm. Here the schools had been closed, the restaurant dining rooms had been shut, and people had been told to work from home whenever they could. Even the sheltered workshop where my oldest son worked had been closed until further notice. People had made a run on the stores and large areas of the shelves were bare. On the news the numbers of the sick and dead continued to rise. It felt like there was a weight on the souls of everyone in the world.My family were staying at home as much as possible and as I looked out of my window I wondered how long this crisis would last. It was then, however, that I saw something that lifted that weight off of my soul, made me smile, and made my heart feel happy again. On the street below my house there was an old friend of mine from high school who was a teacher there. With him was my younger son's former aide from the high school as well. They were delivering the school lunches door to door to the hungry children who were stuck at home. Watching them made me think of something everyone's childhood television neighbor, Mr. Roger's once said: "In the bad times, always look for the helpers."I have no doubt that this crisis will pass as all the crisis before. But it is our choice on whether it brings outthe best in us or the worst in us. Let it bring out the best in you. Use it to strengthen your faith. Use it to free yourself from fear. Use it to grow kinder, more giving, and more loving. Become a helper to all those in need and you will be a happy person today and all the days to come.8. Why didn't the author like the first day of spring?A. He had to work at home instead of at office.B. There wasn't social distance between each other.C. There was an epidemic everywhere in the world.D. His own company had been closed for a long time.9. How did people feel in the face of the epidemic?A. Disappointed.B. TenseC. Confident.D. Cheerful.10. What made the author happy?A. Seeing someone delivering lunches from door to door.B. Talking with his old friend in the street.C. Watching a childhood television at home.D. Staying together with his family.11. What do Mr. Roger's words actually mean?A. It's not necessary for us to find helpers in bad times.B. In good times we needn't do much to help others.C. We should ask more people to help us in bad times.D. We are supposed to help each other in bad times.DIn recent years,people have been focusing on the quality of food that children are fed in schools. Former First Lady Michelle Obama worked hard to make school lunches healthier, resulting in new menus that featured less fat and salt, more fruits and vegetables.But high-quality nutrients count for little when there is no time to eat them. Amy Ettinger reports, "There is no national standard on how much time kids get to eat that meal. " And with schools being occupied with test scores, teachers are using every available minute for lesson time, which often leaves kids without enough eating time.This is a problem because the length of the school lunch period is a key factor (因素) in how much nutrition children actually gel. Research has found that having less than 20 minutes for lunch results in children consumingmuch less of their lunch than those with more than 20 minutes.This is really terrible. For many low-income kids, that cafeteria lunch can represent half their daily energy intake. There's also another terrible message that it's acceptable to wolf down food as fast as possible before rushing off to your next class. Cafeteria time should be a chance to interact with friends, to learn important social skills, to observe and share varieties of food. It should be a break in day, a chance to relax before heading into the afternoon.As Ettinger explains,some parents are hoping the National Parent Teacher Association will address this issue. This, in turn, would help parents push their kids' schools for better lunch time standards. Meanwhile, if you have a kid in this situation, you can help by packing a healthy lunch to spare them the cafeteria lineup. Make the foods easy to eat, provide non-messy snacks that can be eaten in class, put great effort into serving a hearty breakfast, and sit down as a family for dinner whenever possible.12. What did Michelle Obama make efforts to improve?A. The quality of school lunches.B. The performance of school kids.C. The school lunch time kids have.D. The eating habits of school kids.13. What happens to children in American schools?A. They are occupied with many tests.B. They fail to get along with each other.C. They consume more meat than before.D. They have less lunch time than before.14. How are low-income kids influenced by the problem at school?A. They can't go to classes on time.B. They can't have enough energy.C. They can't share different kinds of food.D. They can't hold a positive attitude toward life.15.What can parents do to solve the problem?A. Prepare a better lunch for their kids.B. Stop their kids going to the cafeteria.C. Force schools to make adjustments to lunch.D. Guide their kids on how to pack their own lunch.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。
2020年北京市海淀北部新区实验中学高三英语期中试卷及答案
2020年北京市海淀北部新区实验中学高三英语期中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.B14 days. That’s the time Chinese scientists took to identify the full genetic sequence of the novel coronavirus (新冠病毒) since its outbreak. It was shared with the WHO immediately, and has now become an important foundation for global researchers in the fight against the COVID-19. But first, let us turn the clock back 17 years, when it took months to identify the SARS virus. From months to 14 days, what changed? It turns out AI played an important part.The scientists first obtained bronchoalveolar lavage (BAL) fluid (支气管扩张灌洗液) samples from patients, isolated (分离) the DNA and RNA, then sequenced the genetic material by comparing them. AI’s advantage is its ability to recognize patterns among a flood of data.Let me put it in a simple way. Sequencing the coronavirus genome (基因组) is similarto looking for a needle in a haystack (干草堆)---looking for genotypes (基因型) with specific characteristics from a huge gene pool. That’s where search algorithm (算法), a branch of modern AI, comes in. Think of it as an efficient search engine, which can find the needle in the haystack. This search algorithm can shorten months-long genetic sequencing to weeks or even just a few days. Combined with macro-genomic sequencing and a virus library, this AI technology can also be used in tracking virus mutation (突变).AI doesn’t just support scientists. It can also help patients by improving the efficiency of diagnosis (诊断).Chinalaunched a Genomics Service, which can run multiple virus gene comparisons and produce a detailed report within 60 seconds. This algorithm hasbeen put into use inChinaand shared to the world for free.4. AI’s advantage is that it can ________.A. slow down the spread of coronavirusB. separate DNA from RNAC.identify specific genotypes rapidlyD. obtain samples from patients quickly5. The search algorithm helps shorten the time of genetic sequencing by __________.A. finding a needle in a haystackB. serving as a search engineC. combining with a virus libraryD. tracing virus mutation6. What do we know about the Genomics Service in the last paragraph?A. It has been widely used in the world.B. It is mainly based on blood test.C. It is for fast diagnosis of COVID-19.D. It is used to track COVID-19 patients.7. What’s the best title of the passage?A. 14 Days---ChinaMade it!B. AI Assists in COVID-19 FightC. Search Algorithm, Best ChoiceD. China’s Genomics ServiceCGray wolves have lived inNorth Americafor at least half a million years. Their living areas once included most of the continentalUnited States. But during the 1800s and early 1900s, wolves were hunted to near extinction(灭绝).By the 1960s, theU. S.wolf population was limited to a handful of creatures in small comers of the northernMidwest.Then, in 1973, a law, the ESA, was passed to protect animals from becoming extinct. Gray wolves were one of the first animals placed on the endangered-species(濒危物种)list. Killing them wasillicit. And theU. ernment worked to promote their protection. In a famous example of this effort, starting in 1995, 31 wolves were moved fromCanadatoYellowstoneNational Park. By 2015, more than 500 gray wolves were living in the Greater Yellowstone Ecosystem(生态系统).Today, the continentalU. S.is home to more than 6,000 gray wolves. On January 4, 2021, theU. ernment removed gray wolves from the endangered-species list.Usually, an animal's removal would be cause for celebration. But some environmental protectors say the wolves still need protection. In some parts of the country, wolves are increasing in numbers. More than a thousand of them can be found just inMichiganandWisconsin. But overall, their range is still a small part of what it was. Wolves used to live across most of the U. S. Now they , are found in fewer than a dozen states. Others argue that as long as a species is not in danger of extinction, it doesn't belong on the endangered-species list. And farmers with land near wolf living areas say that if the wolf's population continues to grow, more of their farm animals will be killed by wolves.But some protection groups worry that without protection, the wolf population will crash again. They hope that no matter what, people and wolves can get along peacefully with each other. They are promoting ways to make that happen.8. What caused gray wolves to be almost extinct?A. Losing their living areas.B. Too many natural enemies.C. The extreme climate changes.D. Being hunted in great numbers.9. What does the underlined word "illicit" in paragraph 2 mean?A. Rather difficult.B. Against the law.C. Totally normal.D. Conditionally allowable.10. Why was the gray wolf removed from the endangered-species list?A. They have a much larger population already.B. They have all been put into the safe natural parks.C. They have been feeding on farmers, farm animals.D. They have grown too strong to be protected by humans.11. What do farmers living near gray wolves' living areas think of the animals?A. The wolves are trouble for them.B. The wolves must be better protected.C. The wolves get along peacefully with them.D. The wolves should live where they belong.DLife in the Internet age is lonely—or is it? That’s what experts in human interaction are debating after a new Stanford University survey has been published.According to the study, the more time people spend online, the less they can spare for real-life relationships with family and friends. The researchers asked 113 people about the Web’s influence on daily activities. 36％of those people are online for more than five hours a week.” As Internet use becomes more widespread, it will have an increasingly isolating (孤立的) effect on society,” says Robert Kraut, one of the researchers.Scholars and Web lovers criticized the study for stretching its data to make the “isolating” point. While 13％of regular Web users admitted the loss of time with loved ones, 60％reported watching less TV. The survey also shows that E-mail is the most popular online activity. If some of webheads (网虫)spend what was once passive TV time keeping company with friends via E-mails, “that’s a move toward greater connectedness,” says Paul Resnick, a professor at the University of Michigan.Thisisn’t the first claim that the Web should be criticized. A 1998 report monitored 73 Pittsburgh-area families’ Net use for a year. People who used the Internet more “talked less to family members and reported being lonelier and more depressed.” says Robert Kraut.“It’s true that there have been big declines in social connectedness over the past decades, but those declines began before the Internet was invented,” says Thomas Putnam.As Amitay Etzioni says, the Internet gives us a different kind of social life—not better or worse than before,but just different.12. Who claimed that the Web had negative influence?A. Paul Resnick.B. Robert Kraut.C. Thomas Putnam.D. Amitay Etzioni.13. The underlined word “This” in Para.4 refers to .A. the opinion expressed in Bowling AloneB. the survey made by the University of MichiganC. the conclusion in a report written in 1998D. the study conducted by Stanford University14. From the passage we learn that .A. watching TV used to take time away from staying onlineB. the Web was blamed more than once for causing an isolating effectC. 36％ofweb users spend more than five hours a week onlineD. the Web has the same influence as telephones and televisions15. The passage mainly discusses .A. how we can make a better use of the InternetB. how declines in social connectedness appearC. whether the Internet causes an isolating effectD. what a different life the Internet brings to us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。

It can help you manage weight, keep blood sugar levels down and reduce risk factors for heart disease.Now, a new study suggests that regularly playing sports, especially badminton or tennis, is not only healthy but also reduces your risk of death, at any age, by approximately 50%. This is a big scale population study to explore the health benefits of sports in terms of death rate. The study evaluated responses from 80, 306 adults aged 30 and above inEnglandandScotland, who were surveyed about their health, lifestyle and exercise patterns.After adjusting factors such as age, sex, weight, smoking habits, alcohol use, education and other forms of exercise besidesthe named sports, the researchers compared the risk of death among people who took part in a sport to those who didn’t. The percentage of reduced risk of death was found to be: 47% for racket（球拍）sports, 28% for swimming and 15% for cycling.In addition to this, the study didn’t find any significant reduction in the risk for sports like running and football. The findings also exposed that over 44% of the participants met the guidelines for the recommended exercise levels to stay fit and healthy, which amounts to 150 minutes of moderate(适度的) physical activity in a week.Does this mean you stop running or playing football and switch to tennis instead? Every kind of sport and physical activity has different physical, social and mental benefits attached to it. The apparent lack of benefits of running and football could result from several variables that were not taken into account.Being active helps you feel happier and live longer. So, the most important step is to take part in any kind of sport that you are likely to enjoy and follow in the long term.4. How is the study conducted?A. By doing comparative experiments.B.

Stop running and playing football.D. Do any sport according to guidelines.CAccording to statistics published by the BPI (Buying Power Index) a couple of months ago, digital streaming (流媒体) now accounts for 80 percent of the music consumption in the UK. Despite the incredible growth of online streaming platforms like iTunes, Apple Music and Tidal over the past 15 years, a more traditional medium has also seen a return of interest and sales in the music industry. In 2020, almost one in five of all albums purchased in the UK is vinyl (黑胶唱片), and it has once again become the most popular physical musical medium.With digital streaming so easy and convenient, why are so many peopledrawn to traditional records? Some experts claim that vinyl is a physical medium for experiencing music, something tangible (有形的) to hold and own. For most people, having something tangible and interacting with it gives depth to the experience of music.Listening to an album and touching it the way the artist intended can make them feel more connected to the music and the artist. Records are physical products that can be not only displayed but also gifted, shared, traded and passed down through generations.Sound quality is another hot topic. A lot of music lovers feel that the analogue sound (模拟声音) vinyl offers is superior to modern digital audio, particularly with regards to the compressed formats streaming platforms use. There’s a common belief that old-school analogue audio has a warmer, fuller sound than digitised music. For vinyl followers, the very defect traditional recorders often have, such as the familiar crackle (劈啪作响) when the record starts, bring the music to life in a different way.There’s aritualisticaspect to vinyl that a lot of people are drawn to, too. The act of putting a record on—carefully removing the record from the sleeve, placing it on the record player and gently dropping the needle on the right groove (凹槽)—is a more assiduous (一丝不苟的), mindful way of engaging with music. When you’re listening to vinyl, you can’t tap abutton and go about your day while the streaming service provides hours of music. You need to stay close to the record player to move the needle and flip the record over.It’s clear that the vinyl interest is well underway, and vinyl records are truly making a comeback. In an increasingly digital society, there’s something to be said for analogue experiences. Perhaps one of the great things about being alive in the 21st century is our ability to have the best of both worlds—the timeless appeal of physical records alongside the easy access to vast music libraries that streaming offers.8. What are the statistics published by the BPI used to show?A. An increase in music consumption.B. The recovery of music industry.C. A comeback of a physical medium.D. The acceptance of online streaming.9. According to some experts, why does vinyl interest many people?A. It attracts people by its realistic feel.B. It offers simple access to different music.C. It shares a new way to enjoy music.D. It provides people with perfect sound effect.10. The underlined word “ritualistic” in Para.4 means something ______.A. Overlooked by society.B. Updated very frequently.C. Performed as part of a ceremony.D. Kept for a long time without changing.11. How does the writer feel about the future development of music medium?A. Traditional records will get underway.B. The analogue experiences may matter more.C. Vinyl sales will boom with technological advance.D. There should be a good mix of old and new.DAfter almost an entire year of not going shopping and vacationing, you find the numbers reflected by your bank account meet your heart’ s desire.Now the most important question comes, what to do with the earnings? Should you fulfill dreams of the present, invest in preserving the future or perhaps keep saving it for a rainy day?Our elders always try to teach us the value of money and its moral weakness. One may be on a winning streak (连续成功) now, but it will not always be so. One will have days when there will be no sunshine but only rain, and their luck will hide behind those thick grey clouds. Save for those rainy days, they say. Do not spend too much, live within a budget,refrain fromcredit no matter how small and save for the future.Since the very first time we earn our own money from a summer job or earning our first salary, the lessons start. In fact, the pocket money that we receive when we are children begins the process of learning how to best manage one’ s money.People often think like this — one day when I have enough money, I will travel the world. Then, once we do earn enough money, tomorrow’ s plans start shadowing our present ones. However, is it wise to keep living for that future? Will we still enjoy or even be able to backpack in our 50s? How will we ever enjoy our present if we are constantly living for the future?Good questions, aren’ t they? I say travel but don’ t let yourself run dry, treat yourself to some luxuries but also keep enough for your necessities, and enjoy your present but with a plan for the foreseeable future. Life is for the living, so live it sensibly.12. Why do elders teach us to save money?A. Because there are more rainy days in life.B. Because no one can win streak.C. Because good days may end.D. Because money can’t buy everything.13. What does the underlined phrase “refrain from” mean in Paragraph 3?A. select fromB. hold backC. rely onD. prefer to14. Which of the following opinions would the author agree?A. To enjoy yourself in the right time.B. To wait to travel until we have enough money.C. To go backpacking in our 50s.D. To live for the future.15. What should we do with the earnings according to the author?A. We should save all for rainy days.B. We should fulfill our dreams.C. We should entertain ourselves.D. We should live the present wisely.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。
