04 七选五专练(解析版)-2020-2021学年上学期高一英语期末专项训练
高一上学期期末专项训练4 七选五01Things I Wish I'd Known in High SchoolSometimes high school seems like a necessary evil. Now at the end of my college journey, I know that there are still more things I could have done to make my high school experience more beneficial.1Take a class that scares you during high school. The experience will definitely prepare you for future academic challenges.Don't worry about your grades too much. Getting a B is not the end of the world. 2I have started college with all A's since seventh grade, and it was hard to deal with not being able to repeat that. I stayed away from taking some harder courses I might have done well in because I was afraid of doing poorly. Now, I can fully accept that if I try my best in at least one harder class and get a B+, that is still something to be proud of.Find your own de-stressing(解压) routine. Another essential skill to begin building in high school is how to manage work and stress. Maybe you deal with stress by going for a run, or watching a silly movie. Talk with a friend for a while or play with your dog.3Spend your summers wisely. Don't take on a full-time job the first summer you decide to work.4Do find something to do that will make the ten weeks worthwhile. Look for programs that take you to interesting places, or a job that will give you insights into something you might be interested in.Finally, remember to have fun. Your life does not depend on high school. 5You will have plenty of time to work hard in college and beyond. Be prepared, but don't stress out too much about it. If you can make your high school experience fun, you will have no problem doing the same for your life in college and beyond.A.In fact, it's a kind of good thing.B.Take full advantage of your brain.C.You do have to be active in making friends.D.Do your best, but leave time for fun with friends.E.They will be improved if you make great efforts.F.Find out what relaxes you, and you will feel less stressed.G.Forty hours a week will be a huge shock and you'll have plenty of time for that in the future.1. 2. 3. 4. 5.答案[语篇解读]作者讲述了上高中应该做的几件事。

B.A traveler's journal.C.A news report.D.A trip guide.BA single toy catches a child's attention for a limited period of time, but a box of items that allows a child to build their own toys will catch their imagination for years to come. This brilliant idea already exists in real product form, and it's called Toyi.Toyi is described as an eco-friendly creative building kit, and it recently won the well-known IF Design Award. It came from Istanbul, Turkish, where a young female designer named Elif Atmaca first came up with the idea for it when she wanted to help the kids living in disadvantaged areas. These children do not have access to the variety of interesting toys that wealthier children do.Toyi Atmaca's design allows children to transform what are around them into clever toys. It consists of sticks, junction parts, flexible connectors, toy body parts like feet, eyes, hands, and wheels that can be used to turn old water bottles, cups, boxes, towels, etc. into cute, clever, and unique playthings. This toy kit upcycles(升级利用) materials that would otherwise go to waste, turning a recycling bin into a treasure container.“Our initial target was to deliver Toyi kits to only disadvantaged children in Turkish,” Atmaca told the media. But during a research conducted with around300 children, .she realized that the restriction on being creative went beyond any boundary. “I saw that everything was planned and shaped by grown-ups, blocking the kids' imagination in a significant way,” said Atmaca.Atmaca concluded that each kid needed space where he or she could freely create. She explained the entire process should be left to kids’ creativity, reminding teachers and all grown-ups that child-led play was an excellent way for children to develop lifelong skills.Toyi's creators are now considering distributing the kits to as many children as possible around the world through different international NGOs. Atmaca notes that for each Toyi kit sold out, they will also donate one kit to a disadvantaged child through different partnerships around the world.4. Why did Atmaca design Toyi at first?A. To win the famous IF Design Award.B. To help poor kids make their own toys.C. To protect the environment in Istanbul.D. To recycle all the waste in the dustbin.5. Which is probably the product made with the toy kit of Toyi?A. A new picture of a young boy.B. A computer with high technology.C. A treasure container from a dustbin:D. A six-armed “robot” from a water bottle.6. How do the toy kits help improve the children's ability?A. It provides the kids various types of toys.B. It offers space for the kids’ creative minds.C. It changes the poor kids' living conditions.D. It teaches the kids to share joys with others.7. What is the new target for Atmaca and her partners?A. Donating toykits to more poor children.B. Selling toy kits to every kid in the world.C. Designing new toy kits for kids and adults.D. Doing further research on the kids' demands.CIn 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 consuming much 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 energyintake. 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.8. 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.9. 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.10. 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.11.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.DIn the summer of 2016, I gave a talk at a small conference in northernVirginia. I began by admitting that I’d never had a social-media account; I then outlined arguments for why other peopleshould consider removing social media from their lives. The event organizers uploaded the video of my talk to YouTube. Then it was shared repeatedly on Facebook and Instagram and, eventually, viewed more than five million times. I was both pleasedand annoyed by the fact that my anti-social-media talk had found such a large audience on social media.I think of this event as typical of the love-hate relationships many of us have with Facebook, Instagram, and other social-media platforms. On the one hand, we’ve grown cautious about the so-called attention economy, which, in the name of corporate(公司的) profits, destroys social life gradually and offends privacy. But we also benefit from social media and hesitate to break away from it completely. Not long ago, Imet a partner at a large law firm in Washington, D.C., who told me that she keeps Instagram on her phone because she misses her kids when she travels; looking through pictures of them makes her feel better.In recent months, some of the biggest social-media companies, Facebook and Twitter, in particular, have promised various reforms. In March, Mark Zuckerberg announced a plan to move his platform toward private communication protected by end-to-end encryption(端对端加密); later that month, he put forward the establishment of a third-party group to set standards for acceptable content.All of these approaches assume that the reformation of social media will be a complex, lengthy, and gradual process. But not everyone sees it that way. Alongside these official responses, a loose collective of developers that calls itself the IndieWeb has been creating another alternative. They are developing their own social-media platforms, which they say will preserve what’s good about social media while getting rid of what’s bad. They hope to rebuild social media according to principles that are less corporate and more humane(人道的).12. Why did the author feel annoyed when his video was spread online?A. His video caused many arguments.B. His video was shared without his permission.C. His talk was opposed by a large amount of people.D. His video’s popularity on social media is against his talk.13. Why does the author mention the story of his partner in paragraph 2?A. To prove that social media has some benefits.B. To advise people to break away from social media.C. To tell the negative effects social media may produce.D. To describe people’s complicated relationships with social media.14. What is the purpose of the reform made by some social-media companies?A. To attract more users.B. To improve network environment.C. To make more profits.D. To provide more convenientservice.15. What does the IndieWeb intend to do?A. Develop new social-media platforms.B. Remove social media from people’s lives.C. Improve the existing social-media principles.D. Help social-media companies to make reformation.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。

So what’s wrong with purple? It’s such a popular color1 today. Why would no country use it in their flag? The answer is really quite simple. Purple was just for too expensive.The color1 purple has been associated with royalty power and wealth for centuries. Queen Elizabeth I forbade anyone except close members of the royal family to wear it. Purple’s high status comes from the rarity and cost of the dye (染料)originally used to produce it. Fabric traders got the dye from a small sea snail (海螺)that was only found in the Tyre region of the Mediterranean. More than 10,000 snails were needed to create just one gram of purple; not to mention a lot of work went into producing the dye, which made purple dye so expensive.Since only wealthy rulers could afford to buy and wear the color1 , it became associated with the royal family. Sometimes, however, the dye was too expensive even for royalty. Third century Roman Emperor Aurelio famously wouldn’t allow his wife to buy a scarf made from purple silk because it cost three times its weight in gold. A single pound of dye cost three pounds of gold, which equals 56,000 dollars today. Therefore, even the richest countries couldn’t spend that much having purple on their flags.The dye became more accessible to lower-class about a century and a half ago. In 1856, 18-year-old English chemist William Henry Perkin accidentally created a man-made purple compound (化合物)while attemptingto produce an anti-malaria drug. He noticed that the compound could be used to dye fabrics, so he patented the dye, manufactured it and got rich. Purple dye was then mass-produced so everybody could afford it.Till now, a handful of new national flags have been designed and a few of them have chosen to use purple in their flag. So don’t be making any bets just yet.4. Why was color1 purple expensive in the past?A. Because only royal families were allowed to wear purple.B. Because it took a long time to get purple dye from gold.C. Because purple was worth as much as its weight in gold.D. Because purple dye used to be rare and hard to produce.5. Why did Roman Emperor Aurelio forbid his wife to buy a purple scarf?A. Because of poor quality.B. Because of long tradition.C. Because of bad taste.D. Because of high price.6. What is purple's situation now?A. Purple has been widely used on national flags.B. Purple dye is now affordable to ordinary people.C. Royal family stop using purple because it’s toocommon.D. Fewer snails are used to produce purple dye than before.7. Which of the following would be the best title for the passage?A. No Purple Flags?B. Purple vs GoldC. How to Produce Purple Dye?D. The Birth of Purple ColorCLife 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.8. Who claimed that the Web had negative influence?A. Paul Resnick.B. Robert Kraut.C. Thomas Putnam.D. Amitay Etzioni.9. 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 University10. 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 televisions11. 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 usDClara Daly was seated on an Alaska Airlines flight from Boston to Los Angeles when a flight attendant asked an urgent(紧急的) question over the loudspeaker: “Does anyone on board know American Body Language?” She knew she needed to help.Clara, 15 at the time, pressed the call button. The flight attendant came by and explained the situation. “Wehave a passenger on the plane who’s blind and deaf,” she said. The passenger seemed to want something, but he was traveling alone and the flight attendants couldn’t understand what he needed, according to PEOPLE magazine.Clara had been studying ASL for the past year to help with her dyslexia (阅读障碍) and knew she’d be able to spell on the man’s palm(手掌) by finger. So she unbuckled her seat belt, walked toward the front of the plane, and knelt by the aisle seat of Tim Cook, then 64. Gently taking his hand, she wrote, “How are you? Are you OK?” Cook asked for some water. When it arrived, Clara returned to her seat. She came by again a bit later because he wanted to know the time. On her third visit, she stopped and stayed for a while.“He didn’t need anything. He was lonely and wanted to talk,” Clara said. So for the next hour, that was what they did. She talked about her family and her plans for the future (she wants to be a politician). Cook told Clara how he had gradually become blind over time and shared stories of his days as a traveling salesman. Even though he couldn’t see her, she “looked attentively at his face with such kindness”, a passenger reported.“Clara was amazing,” a flight attendant told Alaska Airlines in a blog interview. “You could tell Cook was very excited to have someone he could speak to, and she was such a warm-hearted girl.” Cook’s reaction: “Best trip I’ve ever had.”Looking for ways to offer help? Start with this random(随时的) act of kindness that can change someone’s life right now.12. The flight attendant asked an urgent question because ________.A. the passenger was traveling aloneB. the plane was in a dangerous situationC. the passenger asked for something suddenlyD. none of the flight attendants could communicate with the passenger13. Why did Clara talk about her plans for the future?A. Because the flight attendant asked her to do so.B. Because she needed topics to go on talking with Cook.C. Because Cook hoped to understand teenagers better.D. Because she wanted to show her dream for the future.14. Which of the following words can best describe Clara?A. Kind and caring.B. Warm-hearted and brave.C. careful and calm.D. opened-minded and confident.15. The passage is mainly written to ________.A. tell a touching story of an amazing girlB. show the great importance of American Body LanguageC. encourage readers to give a hand kindly and randomlyD. show how kind the flight attendant was to help Cook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。

PaymentBSummer heat can be dangerous, and heat leads to tragedy far toooften. According to kidsandcars, org, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.For Bishop Curry, a fifth grader from Mckinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry, who turned 11 this year, has always had a knack for inventing things, and he drew up a sketch (草图) of a device he called “Oasis.”The device would attach to carseats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the carseat, it would begin to circulate cool air. Curry alsodesigns the device using GPS and Wi-Fi technology, which would alarm the child’s parents and, if there was no response from them, the police.Curry’s father believes that the invention has potential. “The cool thing about Bishop’s thinking is none of this technology is new,” he said. “We feel like the way he’s thinking and combining all these technologies will get to production faster.” His father even introduced the device to Toyota, where he works as an engineer. The company was so impressed that they sent Curry and his father to a car safety conference in Michigan.In January, Curry’s father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. Their goal was $20,000, but so many people believed in Oasis’ potential that they have raised more than twice that — over $46,000.Curry’s father remembers the first time he saw his son’s sketch. “I was so proud of him for thinking of a solution,” he said. “We always just complain about things and rarely offer solutions.”4. What inspired Curry to invent Oasis?A. His narrow escape from death after being locked in a car.B. His knowledge of many children’s death because of car heat.C. The death of his neighbor’s baby after being left in a hot car.D. The injury of 37 children in his school in a car accident.5. What would Oasis do if it was hot in a car with a child?A. It would inform the parents or even the police.B. It would pump out the hot air in the car.C. It would sound the alarm attached to the car.D. It would get the window open to save the child.6. What does Curry’s father think is cool about Curry’s invention?A. It used some of the most advanced technology.B. It simply combined technologies that existed.C. It could accelerate production of new technology.D. It is the most advanced among similar products.7. Why did Curry’s father start a campaign to raise money?A. To conduct experiments to test the invention.B. To get other children devoted to inventions.C. To support a charity of medical aid for children.D. To get the patent and bring it to production.CA lot of us lose life’s tough battles by starting a frontal attack—when a touch of humor might well enable us to win．Consider the case of a young friend of mine，who hita traffic jam on his way to work shortly after receiving an ultimatum about beinglate on the job．Although there was a good reason for Sam’s a being late—serious illness at home—he decided that this by-now-familiar excuse wouldn’t work any longer．His supervisor was probably already pacing up and down preparing a dismissal speech．Yes，the boss was．Sam entered the office at 9：35．The place was as quiet as a locker room；everyone was hard at work．Sam’s supervisor came up to him．Suddenly，Sam forced a grin and stretched out his hand．“How do you do！” he said．“I’m Sam Maynard．I’m applying for a job，which，I understand，became available just 35 minutes ago．Does the early bird get the worm？”The room exploded in laughter．The supervisor“clamped off”a smile and walked back to his office．Sam Maynard had saved his job—with the only tool that could win，a laugh．Humor is a most effective，yet frequently neglected，means of handling the difficult situations in our lives．It can be used for patching up differences，apologizing，saying “no”，criticizing，getting the other fellow to do what you want without his losingface．For some jobs，it’s the only tool that can succeed．It is a way to discuss subjectsso sensitive that serious dialog may start a quarrel．For example，many believe that comedians on television are doing more today for racial and religious tolerancethan people in any other forum．8. Why was Sam late for his job？A. Because he was ill．B. Because he got up late．C. Because he was caught in a traffic jam．D. He was busy applying for a new job．9. The main idea of this passage is ________．A. Sam Maynard saved his job with humorB. humor is important in our livesC. early bird gets the wormD. humor can solve racial discriminations10. The phrase “clamped off” in Paragraph 3 means ________．A tried to hold back B. tried to setC. chargedD. gave out11. Which of the following statements can we infer from the passage？A. Many lose life’s battles for they are lacking in a sense of humor．B. It wasn’t the first time that Sam came late for his work．C. Sam was supposed to come to his office at 8：30．D. Humor is the most effective way of solving problems．DAs a basic food in the Asian diet，soybeans（大豆）have been used to make tofu and soy milk for hundreds of years．But now，they are also being turned into an alternative to plastic wrap．William Chen，a professor of foodscience and technology at Singapore's Nanyang Technological University，invented the environmentally﹣friendly food wrap．It's made of cellulose（纤维素），a form of fiber，obtained from the waste generated by soy bean product producers．The beans are pressed tosqueeze out juice that's used to make tofu and soy milk．And what's left is usually thrown away，but Chen takes the waste and puts it through a fermentation（发酵）process，during which cellulose is produced．Cellulose﹣based plastic wraps have been on the market for a few years，but Chen says that most are made from wood or corn，grown for that purpose．By contrast，his wrap is made from a waste product，which doesn'tcompete with other crops for land and is more sustainable．Chen's technology could help to solve two problems at once：cutting plastic production and reducing the amount of food waste．"In Singapore，the amount of food waste generated every year could fill up 15，000 Olympic﹣sized swimming pools，" Chen says．F&N，a soy﹣based drinks producer，has partnered with Chen's lab and provides the product，straight from the factory．The company is conducting a study to assess whether the food wrap could complete commercially with conventional products．Chen adds，"The soy﹣based wrap costs almost nothing to makein the lab because the raw materials are free．Commercial production would involve additional expenses，such as storage and quality control，however，we have not calculated those costs yet．"Chen hopes neighboring soy﹣loving countries will be inspired bySingapore to adopt his innovation．"My dream is that our technology，which is cheap and simple，will cut plastic and food waste and create a cleaner environment，" Chen says．12. What is the second paragraph mainly about？A. The introduction to William Chen．B. The process of producing soy milk．C. The way to make soy﹣based wrap．D. The benefit of eating soy products．13. What's the biggest difference of Chen's wrap from other cellulose﹣based plastic wraps？A. It saves land for industry．B. It's more easilybroken down．C. It is made from the food waste．D. It has been put into practice for many years．14. What will commercial production of the food wrap cause？A. A lack of competitiveness．B. Poor quality of the wraps．C. A shortage of raw material．D. An increase in production costs．15. From which is the text probably taken？A. A personal diary．B. A travel guide．C. A book review．D. A scientific magazine．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。

Some cities are already using smart technology to improve the lives of their people.But what exactly does a smart city do? Let's look at a few examples. In the United States cities of Boston and Baltimore, sensors (传感器) in smart rubbish cans can tell cleaning workers how full they are and when they need to be emptied. In Amsterdam, the Netherlands, traffic low and energy usage are monitored and adjusted (监控和调整) according to real-time data (数据) collected from sensors around the city. And in Copenhagen, Denmark, a smart bike system allows riders to check on air quality and traffic jam as they ride.Smart cities will be interactive (互动的), allowing their people to feel like they're truly shaping their environment, instead of only living in it It's very important that we can actually communicate with our environment in a way that we never had in the past Smart cities will also allow us to save resources. By using sensors and 5G networks to monitor the use of water, gas and electricity, city managers can figure out how to share and save these resources more efficiently.Of course, it will take time and money to turn our present cities into the smart cities of the future. But as we've already seen, more cities around the world are already using smart technology in small ways. It won't be long before more cities start to develop their own smart systems.( ) 25.

Some will help us grow, some will hurt us, and some will inspire us to do better. We don't meet people by accident; they' re to cross our path for a reason. We may not realize it at the time of our coming together, but I always do at some point in the future and find I've learnt a lot from them.I come to know the best teachers are those who don't tell you how to pet there but show the way. For them there is no better joy than helping you see a bright future, and seeing you go to levels higher than you would ever have imagined on your own. But that doesn't mean they'll try to fix you or enable you; instead, they guide you to the source of your own power. They believe in you and offer you support.I also learn the importance of never looking down on (瞧不起) someone unless you are helping them up. We like to think of life as a meritocracy (英才管理), so it's easy to look down on someone who isn't as successful or well educated as you are But you've no idea how far he has gone to be here he is now. Be sure we treat everyone with dignity (尊严), for they're worthy to be treated the way you want to be treated.People we meet are like passengers who get on and off the car of our life journey. As they are there to share a certain part of our life, why not take advantage of the chances and learn from them when dealing with them? That way, life is sure to get better.( ) 29.
