2021年四川省成都市青羊区石室中学高考英语一诊试卷一、阅读理解（本大题共15小题，共30.0分）AHaving given good responses to all questions, Thomas, with a perfect resume, failed his job interview last week. Christine, the manager responsible for the interview, showed an actual preference for Thomas but decided to offer the job to her second choice, adding that the fact that he never looked her in the eye said "untrustworthy"."It was not until I attended a diversity workshop that I realized the person we passed over was the perfect person." Christine admitted later. "What I didn't known at that time was that the candidate's odd behavior was simply a cultural misunderstanding. He was an Asian-American raised in a family where respect for those in authority was shown by turning away your eyes. I was just thrown off by the lack of eye contact, not realizing it was cultural," Christine says.As the world becomes smaller and our workplaces become more diverse,it is increasingly essential to expand our understanding of others and to reexamine some of our false assumptions. Mindsets helps organizations and individuals see their own blind spots.Unexpected advantageAt a time when hiring qualified people is becoming more difficult,employers who can have no personal biases have an obvious advantage. A real estate agent illustrates the positive influence of Mindsets-"Coached by Mindsets for two weeks,I acquired how to own a diversified workforce-I employed people from different cultures and skill sets. When the real estate market began to change, it was because we had a diverse agent pool that we were able to stay in the real estate market much longer than others in the same profession."Strategic power"An open mind about diversity not only improves organizations from inside,it is profitable as well." Such comment is from a customer service representative, who shows how an inclusive attitude can improve sales. It wasn't until her boss received Mindsets' training that she was able to understand how important inclusiveness was to customer service. One of the best things my company has done is to contract with a language service that offers translations over the phone. As a result, our customer base has increased."Gender unawarenessGorden is an account executive who attended one of the workshops. "Through some of the lessons,I discovered my personal bias." he recalls. "I had a management position open in my department；and the two finalists were a man and a woman. Had I not attended this workshop,I would have automatically assumed the man was the best candidate because the position required quite a bit of extensive travel. My assumption would have been that even though both candidates were great and could have been successful in the position,I assumed the woman would have wanted to be home with her children and not travel. Thanks to the workshop,I have learnt to make decisions based on fairness."1.Christine's misjudgment about the candidate originated from ______ .A. racial discriminationB. cultural differencesC. gender prejudiceD. physical appearance2.Which of the following statements will Gorden not agree with about Mindsets' workshops？______A. It helped him make fair decisions.B. It helped him discover his personal bias about gender.C. It helped him think more highly of female candidates.D. It helped him successfully find candidates.3.According to the passage, what is Mindsets？______A. A cultural exchange program.B. A personnel training company.C. A real estate agency.D. A non-profit organization.BSeveral years ago, KenKeegan organized a gathering in Las Vegas,with a group of architects involved, who were asked what it would take to design a public school which used 50 percent less energy,cost much less to build and obviously improved students learning. "I think half of them fell off their chairs," Keegan says.Keegan is in charge of the management school facilities for Clark County, Nevada, a district roughly the size of Massachusetts. By 2028，143，000 additional students will enter the already crowded public-education system. Keegan needs 73 new schools to house them. Four architecture teams have nearly finished designing primary school prototypes. With the intention of constructing their schools in 2019，the district will assess how well the schools perform before allowing the winners to conduct their designs in 50 to 70 new buildings.Green schools keep emerging all over, but in Clark County,which stands out for its vastness,such aggressive targets are difficult because design requirements like more natural light for students go against the realities of a desert climate. "One of the biggest obstacles is getting the right site orientation," Mark. Mc,a director at SH Architecture,says. His team recently completed a high school in Las Vegas. "You have the same building, same set of windows, but if its orientation is incorrect and it faces the sun,it will be really expensive to cool."Surprisingly, the man responsible for one of the most progressive green-design competitions has doubts about ideas ofeco-friendly buildings. "I don't believe in the new green religion," Keegan says,"Some of the building technologies that you put forward are impractical. I'm only interested in those that work." But he doesn't mind if some green features inspire students. He says he hopes to set up green energy systems that allow them to learn about the process of harvesting wind and solar power. "You never know what's going to start the interest of a child to study math and science," he says.4.What can be inferred from the architects' reaction in Paragraph 1？______A. Half of them lost balance in excitement.B. Disbelief was obviously seen.C. Most of them expressed little interest.D. They burst into cheers.5.Which order of steps should be followed in carrying out the project？______A. Assessment-Construction-Design.B. Assessment-Design-Construction.C. Design-Construction-Assessment.D. Design-Assessment-Construction.6.What is the biggest challenge Clark County faces if they are to build green schools？______A. The large size.B. Limited facilities.C. The desert climate.D. Poor natural resources.7.In Keegan's opinion, the ideas of green schools are ______ .A. questionableB. out of dateC. advancedD. practicalCNowadays, many of the world's largest brewers （a company that produces beer）are using new technologies to replace the disposable, plastic six-pack beer rings with more sustainable and recyclable materials.Though mostly being used in small test trials,full adoption could have a positive environmental impact,according to some experts. Carlsberg, the Danish brewer,for example,is using glue to adhere cans in a production method that would avoid using 1，200 tons of plastic yearly, or the equal of 60 million plastic bags, once fully adopted.For most consumers, the miserable image of a seagull, turtle, or some other aquatic creature trapped or killed by the plastic rings really arouses their strong sympathy as well as their reflection on the plastic pollution issue. That is a part of the reason why brewers have zeroed in on plastic six-pack-ring packaging. Luckily, children are taught to cut up the rings to lessen the chance that an animal might choke itself to death.Developed by E6PR （Edible Six Pack Ring）programme, which is led by another brewery called Saltwater, the rings made of waste wheat in beer production are now used by 35 brewers across the globe, including in Africa, Europe, and Australia. The final goal is to ensure that they can be eaten harmlessly by aquatic creatures or break down in nature within a matter of weeks rather than the years it will take for plastic.Giving up plastic straws and beer rings may help consumers feel better about their carbon footprint,but some experts say we should also focus on other efforts. Recycling rates in the U.S. stand at just over 34%. Glass, in which many brewers bottle their beer, can be difficult to recycle and transport. If brewers chose thinner glass, the improvement could prove even more beneficial to the environment than giving up plastic rings.However, there can be a risk that consumers may be more likely to litter, if they think the E6PR rings are less harmful. "The idea of creating something that's litter-friendly is an issue in my mind," says Nina Goodrich, executive director of an environmental nonprofit organization, GreenBlue. "What we need in North America is a better system to encourage collection and sorting."8.What does the underlined word "adhere" in Paragraph 2 mean？______A. attach.B. grasp.C. select.D. stick.9.We can learn from Paragraph 2 and Paragraph 3 that ______ .A. Carlsberg has completely relied on the use of glue to stick cans as a production method.B. It is the death of sea animals that draws people's attention to the plastic pollution problem.C. Children are taught to cut up the plastic rings to prevent the rings harming animals.D. Brewers have changed their packing materials due to the pressure from consumers.10.What is the author's attitude towards the E6PR rings？______A. Doubtful.B. Neutral.C. Supportive.D. Indifferent.11.Which statement is true about Nina Goodrich？______A. She wishes to establish a collection and sorting system in America.B. She doesn't think the E6PR rings are harmful for aquatic animals.C. Her team has already produced some litter-friendly materials.D. She is in charge of a charity that works on protecting ocean environment.DWhen we've got children, it's typical of us to give careful thought to how much TV the children are watching and that they're exposed to. Are we being overprotective about the effect reality TV is having on our child？The answer is "No". Or rather, there's increasing evidence that these programmes can have a profound influence on young people.A recent research indicates that some reality TV shows can be every bit as damaging for teenage girls as too many cartoons are for kids - perhaps even worse. The truth is that reality TV is anything but reality - but that's not necessarily what our children believe. A study for the Girl Scout Research Institute in the US found that eight out of ten girls aged between 11 and 17 who regularly watch reality shows believe these programmes describe real life. In fact, much of reality TV is a heavily manipulated view of what's really happening, and the worst of it strengthens the sort of female stereotypes women have spent decades trying to remove.Many of the women on reality TV shows are acting out lives as teenage mothers or drama queens. Strong, hard-working, purposeful young women with ambitions beyond their looks are rare in these programmes. There's a widespread emphasis on the value of women being about how they look and dress, which gives young viewers the message that being a woman is all about style and appearance, not what you do or stand for.Cultural critic and writer Jennifer Pozner describes reality TV as "the contemporary negative reaction against feminism". Imran Siddiquee,Director of Social Media and Outreach,is concerned that these programmes show the worst stereotypes of womanhood and "normalize" them in what appear to be everyday settings. "They offer such a limited view of what it is to be a woman, and all over the world young girls are addicted to it," he says.Siddiquee does recognize, however, that many girls themselves value reality TV. Some say it encourages them to think about situations different from their own. They also point out that some shows feature women running their own successful businesses. "It's important to acknowledge that there are some useful elements in reality TV，" Siddiquee says. "But many girls need to be inspired to think more critically about some aspects of these shows so they're not manipulated by them and so their behaviour doesn't change because of them."We should encourage our children to be critical thinkers and help them develop their media literacy. Whether reality TV is changing our children's views, or whether they are attracted to programmes that agree with their beliefs, it's vital we recognize that their viewing habits could strengthen these unbalanced ideas.12.This passage is most probably intended for ______ .A. Teenage girls.B. Parents.C. Media workers.D. General public.13.What is the problem with a reality TV show？______A. It is too true to life for audience to believe in.B. Actors and directors lack a sense of innovation.C. Its contents and views are rather artificial.D. It has caused controversies among teenagers.14.According to the Imran Siddquee, what should reality TV shows present？______A. Genuine accounts of females and their work.B. Ways to gain more popularity among peers.C. Distinction between true life and TV dramas.D. Tips on how to become stylish young girls.15.What does the text mainly focus on？______A. Situations where teenagers are attracted to certain TV programmes.B. Reality TV shows' impact on young girls and parent's guidance.C. The way to help children to have the habit of critical thinking.D. The stereotypes of women on TV and audience's reaction.二、阅读七选五（本大题共5小题，共10.0分）Looking around the streets of London, you'll definitely see many methods people use to move around.（1）______ Now there's a new addition：electric scooters or e-scooters.This traditional children's vehicle has become more complicated over the years. And now, with the addition of a small electric motor, it's become a cheap and easy mode of transport. Scooting around town can be fun and doesn't involve much effort.（2）______ But considering accidents involving this electric scooter in the U.K.，questions are being asked about their safety and whether traffic laws should be changed.Many e-scooter riders in the U.K. broke the law. Some had been seen on pavements, and others on the road jumped red traffic lights, adding to the frustration of motorists stuck in traffic jams. In the U.K.，the law states that riding one on the public highway or pavement is forbidden. Despite this, it seems the increasing popularity of e-scooters means they can be seen everywhere. （3）______The U.K. government is looking at how safely they can be used on the road and is "reviewing" the law. But its transport minister, Michael Ellis, has told the BBC that "Micromobility products are appearing in countries across the globe and are an exciting innovation, for which we know there is demand.（4）______ "（5）______ Despite the fact that some of them can exceed 30 mph, they sometimes only have one brake and no lights. However confident the rider may be, larger vehicles on the road make them unprotected. So it seems that more work needs to be done to give e-scooters a safe and legal space to travel in.A.The roads are already very crowded.B.What's the best means of transport？C.People seldom see e-scooter accidents in the U.K.D.However, safety must always be our top priority.E.And now users are asking that regulations be changed.F.There's no doubt that there are dangers of riding a two-wheeled scooter.G.It's no wonder that it's becoming increasingly popular in the world.16.

S. theaters and HBO Max on Dec.25，nine days after it starts appearing at cinemas in international markets, Warner Bros.，said in a statement Wednesday. HBO Max subscribers will have a month to see the movie at no additional cost.The film's director, Patty Jenkins, confirmed the move earlier in a tweet, saying that fans should see the movie in theaters if it's safe to do so-otherwise, they can enjoy it at home. Releasing a would-be hit like Wonder Woman 1984 to home and theater audiences meanwhile would have been unthinkable earlier this year, and for decades before that. However, the pandemic has made it impossible for studios to generate the kind of returns at the box office they need to recover their investments in big films. Cinemas in two of the biggest moviegoing markets in the US-Los Angeles and New York City-are closed entirely.Against this background, several major movies from other studios were shown online this year, including Walt Disney Co.'s Mulan. The studios have been typically charging about ＄20 to see those films at home. Wonder Woman 1984 won't have an extra fee, but it will require fans to sign up for HBO Max, which costs ＄15 a month.Under any other set of circumstances, a move like this would be decried by theater owners, whohave long enjoyed the right to exclusively show new hit films for two or three months. However, they've been struck by the effects of the coronavirus. Most cinemas have been closed for portions of 2020 and those that have reopened don't have many new movies to show. Most big films have been delayed until 2021.4.What makes the movie Wonder Woman 1984 different from other movies released thisyear？______A. The approach of releasing.B. The time it will be on show.C. High expectation from audience.D. The theaters where it will be released.5.What does Paragraph 4 mainly talk about？______A. The tough challenges studios have to face.B. Ways for film industry to recover from the pandemic.C. The influence the pandemic has had on film industry.D. The possible success of the movie Wonder Woman 1984.6.What does the underlined word " decried" in Paragraph 6 probably mean？______A. Appreciated.B. Accused.C. Valued.D. Commented.7.Where does this text probably come from______A. A news report.B. A film review.C. A movie advertisement.D. A hit fiction.CDuring the "golden week" national holiday that began on October 1st,hundreds of thousands of sightseers flocked to Lijiang,a picturesque historic town in the south-western province of Yunnan. Among its attractions are the symbols printed beneath the Chinese characters on road signs and shop fronts（Starbucks included）. They are Dongba pictographs,an ancient form of script（文字）that originated among the Naxi,a local ethnic group. It almost died until about a decade ago,when local officials began to realize its value and covered the town with it. Dongba was never widely used by the Naxi,of whom there are about 300，000 living in the Himalayan foothills near Lijiang, as well as in Tibet and Sichuan province. The pictographs,which evolved as early as the seventh century,were developed by shamans （巫师）of the Dongba faith, which has roots in Tibet.Over 20，000 of these religious records survive. They provide rich insight into how Naxi peoplethought about war,geography,astronomy and agriculture. But they are extremely hard to read. Linguists are helped by the area's Dongba priests（神职人员）. There are about 600，most of them very old,including Yang Guoxing, who ran a school from 2010 to 2015 to teach Dongba to children living in the mountains. When Mr Yang was growing up, "everyone was too busy farming" to learn it. Now they are all busy soaking up the pop culture, he says.Signs at bus stations in rural Yunnan encourage locals to use written and spoken Chinese. But the Naxi get off lightly compared with other ethnic minorities. Primary schools in Lijiang teach the Dongba script twice a week, as well as Naxi nursery rhymes. Li Dejing, head of the Dongba Culture Research Institute,says this is not just about keeping alive the pictographs, but letting children grasp "the very spirit of their own culture". And this will also help tourism to develop in Lijiang.8.What do we know about the Dongba script？______A. It is widely used by local people.B. It was a tool used by certain people.C. It was quite popular at certain periods.D. It has a history of more than 3000 years.9.According to Yang Guoxing, what makes it difficult to spread the Dongba script______A. Only priests can read it.B. It's extremely hard to read.C. Its value hasn't been fully recognized.D. People are too busy to learn a new language.10.What has been done to keep the Dongba script alive？______A. New schools are opened to teach it.B. Some tourists are invited to preserve it.C. Only the Dongba script can be used in schools.D. People are more exposed to this language than before.11.What is the best title of the text______A. The Dongba Script Is DyingB. The History of the Dongba ScriptC. The Dongba Script Survives in LijiangD. The Influence of the Dongba ScriptDBig, old trees are dying faster than in the past, leaving younger, less biodiverse forests that store less carbon worldwide. They give us paper and fuel, as well as vital ecological services-like cleaning the air, storing carbon and providing habitat. We're talking about trees, of course. But human changes to the environment appear to be causing profound changes to trees around the world.In a new study, scientists reviewed global research on trends in tree seedlings growth and death. They combined those data with an analysis of deforestation. And they found that worldwide, older trees are dying at a higher rate than in the past due to factors like rising air temperature, wildfires, drought and pathogens（病原菌）."And most of the drivers of that decrease in large, old trees are increasing themselves, such as temperature is going up, droughts are more severe, wildfires, windstorms and deforestation are all on the increase-although variable across the globe-they're generally increasing. And so for both the loss has already occurred, but we expect more continued loss of big, old trees." said Nate McDowell, an earth scientist at Pacific Northwest National Lab, who was one of the study's authors."So if we have an increasing rate of death, particularly of the larger, older trees, what's left are the younger trees. So that's why, on average, through the loss of bigger, older trees, our forests are becoming inherently（天生地）younger and shorter."This trend is a problem, because old trees are vitally important."For sure,the increase in death does limit the carbon storage of an ecosystem and can force the system to become a carbon source to the atmosphere. The second reason we care is from a biodiversity perspective：old trees tend to house a higher biodiversity than young forests do. And the third reason is aesthetic：as a society, we care about these trees. We have national parks named after these big trees. So there's a personal reason for people to care about this as well."12.What has the new study found about the forests？______A. Forests are getting younger and shorter.B. Many factors cause the death of big old trees.C. Old trees are beneficial to humans in many ways.D. The death of big old trees influences biodiversity.13.What do the underlined words " the drivers" in Paragraph 3 refer to______A. The death rates of big old trees.B. The trends in the death of big old trees.C. The human changes to the environment.D. The factors causing high death rate of old trees.14.How is the significance of big old trees illustrated？______A. By giving examples.B. By analyzing reasons.C. By listing facts.D. By providing figures.15.What's the purpose of the text______A. To call on people to protect old trees.B. To illustrate a phenomenon about old trees.C. To share the findings of a new study about trees.D. To analyze the reasons why some trees are dying faster.二、阅读七选五（本大题共5小题，共10.0分）Do you invest too much value into words added by strangers？No matter what you do or say,or how you act,people will always give their opinions about you.（1）______ Otherwise,you'll allow others' opinions to not only hurt you,but often define you. Here are ways to stop caring about what other people think of you.Keep in mind not everyone cares. Everyone is troubled by anxiety, and they might be too busy to immediately recognize yours. （2）______ They're always too busy thinking about their families, work, and whatever else to form a detailed opinion about you.Think about who you want to be. By allowing others' opinions to influence and dominate your life,you're handing them your power. If you can relate to this, ask yourself,what do you want？Are you making these choices only to impress others？（3）______Accept not everyone will like you. In life,some people will like you and others might not.（4）______ But most of the time, that's their mindset only, which has nothing to do with you. There will be people who will accept all of you and people who will be supportive and kind. These are the people who deserve to walk with you.（5）______ You may worry about ending up looking like a fool because of a mistake, but mistakes are unavoidable. When you overcome your fear of making mistakes and build resilience to the pain that may come from failure, you will be unstoppable.

2021年成都市石室中学高三英语第一次联考试卷及参考答案
2021年成都市石室中学高三英语第一次联考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AI started working with my hands at a young age. The youngest of five brothers, I took on the role as a “maintenance (维修) man” at an early age for our family’s small grocery store. Often my dad wouldn’t give me a clear idea of how something shouldbe done, so I just had to figure it out by researching or through trial and error.Fast forward to 2016 and those problem-solving skills would become the focus of Tippecanoe High School’s Homebuilding class. I knew I wanted to teach the students skills that went beyond just being able to hammer nails or cut pieces of two-by-fours. The problem was that we didn’t have the resources at the time to do much else. The idea of attracting some type of funding seemed very important. Designing, building and selling a tiny house on wheels seemed like the perfect project to accomplishthe task. I reached out to a number of local businesses and most of them responded with the greatest support for what x k w we were doing.This year we added a new element to the program. Through one of our partners, we were able to connect with the nonprofit Veteran’s Ananda Incorporated. Students in the Homebuilding class are leading the design and production of micro houses to be donated to this organization. The new partnership gives the students another focus to consider when designing and building the houses.There has been no shortage of students since our first year. Three years ago we had 41 students, the next 191, and this year it was limited to just over 160 students so we could have a safe and manageable classroom environment. The number of girls taking the class has risen steadily over the last few years as well. This class offers something for everyone and the skills are universal.1. How can we describe the young author?A. He opened a small grocery store.B. He did a lot of research in the lab.C. He enjoyed doing hands-on activities.D. He learnt about maintenance from his father.2. What do the underlined words “the task” in paragraph 2 refer to?A. Getting some financial support.B. Selling a tiny house on wheels.C. Reaching out to many local businesses.D. Offering the students some problem-solving skills.3. What can be inferred about the Homebuilding class from the last paragraph?A. Its size needs increasing.B. Itis popular with the students.C. It has caused some safety concerns.D. Its classroom environment is hard to manage.BTo hear people talk about Internet friendships, you would think it was one giant web of cat-fishing and e-crime. While we all undoubtedly have to take measures to remain safe online, assuming every friendship or connection made on Instagram, Twitter or Facebook is cheating or insincere would be a mistake.As a woman who works in the creative industry, I have found real joy in seeking out a community I couldn’t find elsewhere, and making some great friends along the way. My first online friendship was on Twitter with my(now) best friend, during the university exam period. We exchanged study notes in dozens of direct messages, set a study date, and haven’t looked back since.Drawn to each other by similar circumstances, friendships online are similar to offline in that they tend to begin because of shared interest or common ground-maybe they’ve read the post on Instagram. Maybe they have the same taste in food or politics. Or maybe they just love memes too. If online friendships start similar to friendships offline, they grow in the same way, too. Often through mutual support: apart from calling a friend to congratulate him on that new job, you also re-tweet his jokes and praise his Instagram story.Despite my positive experiences when I tell people, most are still suspicious. Eyebrows are raised higher when I explain not only have I found a community online but have made friendships with people I meet face-to-face too. Actually, these are just as valid as other friendships, according to behavioural psychologist Jo Hemmings, who says online friendships can be real.So how do you know if people are there for the real you or just because you’re popular on Instagram? Hemmings has simple rules. She tells me “You have to equally feel comfortable that you’re getting something of each other instead of being used to enable something that isn’t friendship.”Therefore, if all a “friend” online is asking you to do is to promote their work or personal brand and rarely takes an interest in you, then there may be room to question the basis of the friendship. On that note it is worth remembering that just because someone has a lot of followers, it doesn’t necessarily mean they have lots offriends.4. What is most people’s attitude towards online friendship?A. Negative.B. Positive.C. Objective.D. Neutral.5. Why does the writer share her own experience in paragraph 2?A. To introduce the background information of the text.B. To convey the writer’s attitude and give the related example.C. To prove the likely risk for people to develop friendship online.D. To remind people of the various benefits of making friends online.6. How can online and offline friendships be deepened?A. They should be based on shared interest.B. They need to have common ground.C. They require support from each other.D. They can’t live without social media.7. According to the author, what’s the golden rule to make friends online?A. A friend to all is a friend to none.B. Without confidence there is no friendship.C. A friend without faults will never be found.D. Friendship cannot stand always on one side.CWith graduation days being celebrated all over the country, a student who has to use a wheelchair honored his mother on his graduation day in a special way. Easley High School graduate, Alex Mays surprised people present when he got up and walked across the stage at Clemson's Littlejohn Coliseum.“I was really happy—it made me feel good,” Alex said.Alex was not given a chance to live right from his birth. He was born at 25 weeks and weighed just 1 pound, 10 ounces at birth. When he was very young, he had a disease and lost the ability to walk. After his mother's death in 2013, Alex had several other difficult life changes until he came to live with his grandparents, Dousay and her husband, Dewayne. Dousay said that when Alex came to live with them, they decided to bring him up in thebest possible way they could.Last fall, Alex said that he would walk across the stage to get his diploma to honor his late mother. He practiced hard and worked with a physical therapist for 9 months to complete his plan.The only help Alex got was from his mom's best friend, Tonya Johnson, who pushed his wheelchair to the stage wearing one of his mother's favorite shirts. “I had support from my family. I couldn't have done it without them,” Alex said.“Alex made everyone in the building feel encouraged that day” Pickens County School District public information specialist John Eby said. “The school teachers knew he was going to get up to get his diploma, but the distance he walked was a surprise, even to them,” Eby said.“Some of life's most important tests aren’t given in a classroom; Alex tested himself and passed with flying color1 s,” Eby added.8. In what way did Alex honor his late mother on his graduation day?A. By dressing like her.B. By saying sorry to her.C. By inviting her best friend.D. By walking to get his diploma.9. What can we learn from Paragraph 3?A. Alex was born healthy.B. Alex went through a lot.C. Alex had a purpose in life as a child.D. Alex has lived with his grandparents all the time.10. What did Alex also express on his graduation day?A. His big regret in life.B. His feelings for hisschool.C. His thanks for his family.D. His will to complete his study.11. Which of the following words can best describe Alex?A. Strong-minded.B. Warm-hearted.C. Cool-headed.D. Easy-going.DOn the night of September 19, 1961, Betty Hill and her husband Barney were driving home through the White Mountains from Niagara Falls. They were travelling on anearly deserted two-lane highway when Betty noticed a steady light in the sky that was getting bigger and brighter.She thought it was a planet or a star. Barney, stimulated at her excitement, said it was probably just a wandering aeroplane. Whatever it was, it appeared to be following them.They stopped their car for a closer look. What they said happened next, changed their lives. The flying object was noiseless. It appeared to be spinning. It was as big as a jet but shaped like a pancake.So formed the tale of Betty Hill, a New Hampshire social worker who, with Barney, a postal worker, claimed to be kidnapped by aliens, who were from outer space, on a moonlit night about 60 years ago.After reluctantly going public with her experience, Hill, who died of cancer at her New Hampshire home, aged 85, became a celebrity on the UFO circuit and was known as the “first lady of UFOs”.Intriguingly, at the time of the incident, the Hills remembered nothing except that they had spied a strange object in the sky. Later, troubled by nightmares and other stress-related pains, the couple underwenthypnosis(催眠) where the full story came out with the aid of Boston psychiatrist Benjamin Simon, an expert in medical hypnosis.On their night of contact the Hills arrived homeat 5 a.m., unable to account for two lost hours. They were also confused by the odd marks on their telescopes, deep signs on the tops of Barney’s best shoes, Betty’s torn dress and strange circular markings on their car that made the needle of a compass jump wildly.After seeing them for six months, the psychiatrist concluded the Hills’ lost memory about the hours they lost on that night in 1961 “appeared to involve an amazing experience on the part of both of the Hills”. Whether the experience had been fantasy or reality, Simon could not say, but he said he was convinced they had not been lying. He guessed that it had been a kind of shared dream.Reports of aliens capturing humans and taking them aboard oddly shaped spacecraft were “comparatively rare” before 1975. After a movie, “The UFO Incident”, about the Hills came out, however, such stories increased.12. When they saw the strange object in the sky, Barney and Betty Hill ______________.A. were astonished at its strange flight and noiseB. regarded it as just a wandering car following themC. realized immediately what the danger it might causeD. showed curiosity in discovering what it really was13. The word “Intriguingly” in paragraph 6 most probably means “______________”.A. RidiculouslyB. TemporarilyC. RemarkablyD. Mysteriously14. The Hills later sought the help of a psychiatrist because ______________.A. they had lots of secrets in their lives after the strange experienceB. their lives were greatly disturbed by the unexpected experienceC. they wanted to share their unforgettable experience with the expertD. they hoped to forget completely what had happened to them15.

Our sales and office manager was dealing with a team of around seven senior estate agency sales people that were seemingly down on their luck.Only one of them was still making sales and he seemed to have a charm and golden touch that surpasses luck or market forces. Things became very bad and every day we complained about the sales leads we were given. They were from people that had already been surveyed so many times that they were tired and regretted making an enquiry.After a while, things became so bad that the senior management team sent down an executive from another office. This was a man that was doing very well and didn't complain about poor leads or bad market conditions. He told us that the company had purchased a new batch of untapped leads that could be made into sales, but he told us we were not getting them.The senior executive they sent told us that we had to make a sale over the next week or we were all fired. They were looking to replace the staff because the ones on the team at the moment were lame ducks. They also started a scoring system. The person that earned the most duringthe week got a brand-new car；the second most got a new set of steak knives. If you failed to make a sale you were fired.After a lot of phone calls, I finally got an appointment with a couple that had been approached a few times. I was told that they just like to talk to sales agents, but I was not going to let that stop me. I went around their house and talked to them until past two in the morning. At this point, I was holding out a pen and waiting for them to sign. After around twenty minutes of silence, they took the pen and signed, therefore agreeing to purchase six units within an apartment complex.Finally I made my own luck, although not motivated in an appropriate and fair manner.4.Why did some customers regret making an enquiry？______A.

They rush between traffic from restaurants to homes and businesses, regardless of wind or rain. They are food deliverymen. Although they make our life more convenient, this can come at a cost forthem."The food deliverymen are trapped in the app," says an article in the Chinese magazine Portrait, which has triggered a discussion. It pointed out that on food delivery service platforms Eleme and Meituan, the time limit and route for each delivery order is calculated by an algorithm （算法），which doesn't consider real-life situations such as red lights, speed limits and fully occupied elevators.Based on the algorithm, the deadline for a delivery order within 2 kilometers is 30 minutes. Within that time, a deliveryman has to pick up the order and deliver it to the customer. Besides, the time limit has been gradually shortened in recent years. Delay could mean a reduce in pay so deliverymen speed up, often breaking traffic rules and putting people's lives at risk.Many people criticized the platforms and asked them to improve the regulations applied to the deliverymen. In response, on Sept 9，Eleme announced it would add a button to the app, which allows customers to prolong the time limit for their order, and encouraged customers to show more respect for deliverymen. But this created more heated debate, as some felt the company was dodging the problem and distracting attention.They commented that the move was illogical, as the deliverymen are following rules made by their employers, and problems should be solved between the two. They felt the company was putting the responsibility on the users rather than solving the problem themselves. Also, even with the ability to allow more time for delivery, it may not fully address the issue. "If I give them five more minutes, they would not use it to ride slowly or obey the traffic rules. They would simply take one more order. This is not the ultimate cure to solve the problem." Actually it would be better to improve the platform's system and the delivery mechanism. Besides, market regulatory departments should prohibit companies from setting tight schedules for their deliverymen and keep them safe on the roads.8.According to the passage, what can we know about the food deliverymen？______A. The algorithm offers them practical choices of time and routes.B. They have difficulty in meeting the time limit requirement.C. They seldom wear uniforms when they are working.D. They had even shorter delivery time limit in the past.9.What does the word "dodging" in Paragraph 4 probably mean？______A. Solving.B. Avoiding.C. Creating.D. Transforming.10.What do people think of "adding a button to the app"？______A. The company is sparing no effort to address the problem.B. The approach might be the best solution to the problem.C. More potential problems are certain to be brought about.D. Customers shouldn't take responsibility for the problem.11.Which of the following could be the best title of the passage？______A. No Deadlines for DeliverymenB. Deliverymen Break the RulesC. Lightening Deliverymen's LoadD. Shortening the Delivery Time (2021·四川省成都市·模拟题)DAs paleontologists can tell, Neanderthals （尼安德特人）died out around 40，000 years ago. But they did not vanish from the Earth entirely. In the past decade it has become clear that Neanderthals mated with the ancestors of modern humans, and that some of those unions produced offspring （generations to follow）. The result is that almost half of the Neanderthal genome survives, spread in small quantities among most modern people's DNA. The exception is those with mostly African ancestors, for Neanderthals seem never to have lived in Africa. Such genes have been associated with everything from hairiness to fatness. Many seem to be related to the immune system, and to affect the risk of developing diseases including lupus, Crohn's disease and diabetes.A pair of recent papers suggest Covid-19 belongs on that list as well. Two long DNA strings, both inherited from Neanderthals, appear to have resistance or sensibility to severe Covid-19，depending on which is present.The work was led by Hugo Zeberg and Svante Paabo at the Max Planck Institute for Evolutionary Anthropology in Leipzig, whose researchers pioneered the study of Neanderthal DNA.Their first paper, published in Nature in September, described one Neanderthal DNA string, known as a "haplotype"（单体型），which is associated with a higher risk of serious illness. Having one copy of the haplotype, which is found on the third of the 46 chromosomes possessed by humans, doubles the chances of a trip to intensive care. Those unlucky enough to possess two copies, one from each parent, face an even higher risk.That genetic bad luck is not evenly distributed. It is most common among people of South Asia, with 63 percent of the population of Bangladesh carrying at least one copy；and among Europeans, where the rate is around 16 percent. As expected, it is almost absent from Africa.More strikingly, it is also very rare in Eastern Asia.Exactly what the haplotype does is not clear. One gene within it affects a protein that interacts with the cellular receptors （细胞受体）that SARS-CoV-2 （the virus which causes Covid-19）uses to enter cells and control them.The haplotype is also thought to be involved in the production of signalling proteins,called cytokines,which help to regulate the immune system. An overly aggressive immune response is one mechanism by which Covid-19 kills.12.Who are the most likely to carry the haplotype according to the study？______A. Eastern Asians.B. Africans.C. Europeans.D. South Asians.13.What can we learn about the study？______A. The haplotype is equally distributed among people in different races.B. Covid-19 kills partly because the immune system responds to SARS-CoV-2abnormally.C. The haplotype appears to have resistance or sensibility to severe Covid-19.D. People unlucky to have two copies of the haplotype are sure to suffer from seriousillness.14.What is the main idea of the last two paragraphs？______A. Why the Neanderthal genome is related to a higher risk of serious illness.B. What effects the haplotype has on different people in different races.C. Why the haplotype makes people have a higher risk of Covid-19.D. What the haplotype does to affect and regulate the immune system.15.What will the author probably write in the next paragraph？______A. The second study on Covid-19.B. The previous study about Neanderthals.C. The other Neanderthal DNA string.D. The sensibility to severe Covid-19.二、阅读七选五（本大题共5小题，共10.0分）(2021·四川省成都市·模拟题)Making the Most of the Present We've all been asked that question "Where do you see yourself in 5 or 10 years？" and while some of us might have the answers to that, the reality is, most of us don't and that is totally OK.（1）______ We've put together the below tips on how to enjoy living in the moment.Stop worrying about what hasn't happened yet.

Better mood, better life.Put yourself first and stop trying to please everyone else. （4）______ And looking after yourself before anyone else is the most important. Work towards the goals you want to achieve,not the ones others want you to achieve or the ones you think you should be achieving because society tells us too. If you don't want to get married, that's OK，and if you do, that's OK too. （5）______A. No one is better than you.B. You are your own number one.C.
