AIn the fall of 1985, I was a bright-eyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to withdraw from college to care for her. It meant that school and my personal dream would have to wait.Then I got married with another dream: building my family with a combination of adopted and biological children. In 1999, we adopted our first son. To lay eyes on him was fantastic – and very emotional. A year later came our second adopted boy. Then followed son No.3. In 2003, another boy was born.You can imagine how fully occupied I became, raising four boys under the age of 8! Our home was a complete zoo – a joyous zoo. Not surprising, I never did make it back to college full-time. But I never gave up on the dream either. I had only onechoice: to find a way. That meant taking as few as one class each semester.The hardest part was feeling guilty about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to quit, but I knew I should set an example for them to follow through the rest of their lives.In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree!I am not special, just single-minded. It always struck me that when you’re looking at a big challenge from the outside it looks huge, bu t when you’re in the midst of it, it just seems normal. Everything you want won’t arrive in your life on one day. It’s a process. Remember: little steps add up to big dreams.26. Why did the author quit school in her second year of college?A. She wanted to study by herself.B. She fell in love and got married.C. She suffered from a serious illness.D. She decided to look after her grandma.27. What does the author mostly want to tell us in the last paragraph?A. Failure is the mother of success.B. Little by litter, one goes far.C. Every coin has two sides.D. Well begun, half done.28. Which of the following can best describe the author?A. Caring and determined.B. Honest and responsible.C. Ambitious and sensitive.D. Innocent and single-minded.BThe Spring Festival holiday is supposed to be a period of time entirely for family reunion. However, as people’s enthusiasm (热情) for digital hongbao increased, the amount of time they spend with family members during the holiday decreases. There has been widespread criticism (批评) over digital hongbao that it has separated family reunion.“I used to discuss programs in the Spr ing Festival Gala (春晚) with my familymembers, but this year, I barely had time to watch the gala because I was staring at my cellphone all the time,” said Kang, a 30-year-old radio station editor. “I went to karaoke with my cousins during the holiday, and 1 was grasping digital hongbao the whole time, even when I was singing karaoke.”“On the last day of the holiday, I started to regret spending too much time on these digital hongbao. Therefore, instead of fighting for hongbao, I watched TV with my mom that night. I left home feeling so sorry! I should have spent more time with my parents.”But Kang said regret came with a sense of achievement when he managed to bring classmates together.“Next year, I will still play this game, but with less money and for a smaller amount of time,” Kang said.Dong Chenyu, a teacher from Beijing Foreign Studies University, said it’s unfair to blame hongbao for destroying family reunion.“When television was invented, people accused it of standing in the way of face-to-face human communication. The same accusation (谴责) came up on telephone and text message services when they were first invented. The same goes with digital hongbao,” Dong said.“It does nothing but offers a new way of human communication. The rest is people’s choice. As long as no one expects to earn money from this and takes this as a means of gambling (赌博), it’s a good way to improve human connections,” Dong said.29. How did Mr. Kang feel about digital hongbao according to Paragraph 2?A. He felt regretted spending too much money.B. He was happy to spend too much of his time.C. He had a strong preference for it.D. He felt a sense of guilty in getting it.30. From the underlined sentence we know that Mr. Kang felt ___________.A. both regretted and successfulB. either regretted or successfulC. not only happy but also satisfiedD. not pleased but stressed31. What can we infer from what Mr. Dong said about digital hongbao?A. It will bring us trouble in holiday reunion.B. It will be out of fashion in near future.C. Lots of people will use it to earn money.D. Mr. Dong is in favour of digital hongbao.32. Which of the following is the best title of the passage?A. Spring Festival ReunionB. Double-edged SwordC. New Holiday EnthusiasmD. Family Reunion DestructionC“People are ruder today because they are rushed and more ‘time poor’ than ever before,” says Patsy Rowe, “Manners have fallen off the radar (雷达).” Due to our strong attraction to electronic equipment it is a wonder that more people don’t wake up each morning and greet the singing birds with a complaint (抱怨) about the noise. Here are some examples of rudeness.Some people prefer to do almost everything over the Internet. To them, dealing with an actual human is like an evolutionary step backward. It feels very slow because humans don’t work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life-changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous (匿名的) rude messages by email.However, rudeness is never acceptable. Don’t assume it is OK to be rude if the person you’re in touch with won’t recognize you. If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it. Upsetting people with unsigned messages is cruel and disgusting.We shouldn’t blame technology for our shortcomings. Technology is here to help us, but we should not allow it to take over our lives. An important step is acknowledging our shortcomings. People spend a lot of time pointing out bad manners but it would be even more helpful if we’d publicly acknowledge good manners when we see them.33. What can be inferred from the underlined sentence in Paragraph 1?A. People can tell good from bad behavior.B. Radar is able to observe human behavior.C. People care little about their behavior.D. Radar can be used to predict human behavior.34. Some people are less willing to deal with humans because ___________.A. they are becoming less patientB. they are growing too independentC. they have to handle many important messagesD. they have to follow an evolutionary step backward35. The author thinks sending unsigned awful messages is ____________.A. ridiculousB. disgustingC. acceptableD. reasonable36. What can we learn from the last paragraph?A. We should applaud good behavior.B. Technology can never be blamed.C. We should keep pointing out mistakes.D. Technology will take over lives one day.DWanting to lose weight or quit smoking are often resolutions (决心) made at the beginning of the New Year. Meg Baker, one University of Alabama at Birmingham wellness expert says there is a key ingredient to being successful health-wise in the coming year. About half of the most popular resolutions made each year are health-related, according to the United States government. In addition to losing weight and quitting smoking, they include eating healthier foods, getting fit, managing stress and drinking less alcohol.Meg Baker says while the focus on self-improvement is good, an individual must be ready to make a change in order to actually do so.“Readiness to change is a big factor,” Baker said. “Based on the stages of the change model: precontemplation (unwilling to make a change), contemplation (considering a lifestyle change) andaction, you have to want to change your lifestyle to successfully improve your health.”Develop small, short-term goals that will fit into your schedule; these should be realistic. Consider the benefits and reasons for the change. Talk to a family member, friend or co-worker about goals; this accountability (责任) will increase the possibility of your staying committed to a new gym plan or quit-smoking plan, and they may want to join you.Baker says starting small increases the possibility of success. Find a form of exercise that you love, make small nutritional changes like packing a lunch or cooking dinner at home, and get digital reinforcements (增强) by using tracking systems and apps.Additionally, Baker says, because so much time is spent at work, it is a good idea to consider signing up for workplace wellness programs, if offered. “Many companies want to see their employees thrive, so they will offer incentives (鼓励) to help them improve their health, like the My Health Rewards program we are starting at UAB,” Baker said. “Whether it is to improve your energy level, improve mood, combat health conditions and disease, or to be there for your kids’ future, there’s always a reason that a resolution was made,”Baker said.“So when the going gets tough, remind yourself of why you’re making a lifestyle cha nge, and this will keep you motivated.” Also, consider modifications to the new plan if it isn’t viable. Baker said.“If the new plan proves it can’t be done, switch things up. Variety is the key to life and can keep you from getting burned out.37.What does the passage mainly tell us?A. At the beginning of the New Year people want to lose weight.B. At the beginning of the New Year people want to quit smoking.C. Readiness to keep fit is the most popular New Year’s resolution.D. Readiness to c hange is important to commit to the New Year’s resolutions.38.We can know from the passage that ____________.A. if you develop small, short-term goals, you will succeedB. people should not develop big, long-term goalsC. sharing goals with others can help people keep to their plansD. the resolutions made at the beginning of the New Year are hard to achieve39. What’s Baker’s attitude towards the My Health Rewards program?A. Negative.B. Positive.C. Unconcerned.D. Doubtful.40. The underlined word “viable” in the last paragraph can be replaced by _________.A. practicableB. detailedC. originalD. perfect第二节七选五（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

Here are some top options to get closer to various wonderful wildlife.Chester ZooThe newest attractions here are the Madagascar Lemur Walkthrough experience, which gives visitors the opportunity to walk alongside ring-tailed and red-ruffed lemurs, and the interactive American Wetland Aviary, which is home to birds like scarlet ibises and flamingos. Group rates are available for parties of 15 or more and there are various catering options, including sit-down meals at the restaurant at the heart of the zoo.ZSL Whipsnade ZooUntil September 2022, it is offering groups of up to 60 the opportunity to experience a private Nature Night, on which they’ll get to explore the zoo privately after the public has left, take part in activities like quizzes, camp overnight, and get up early for a private tour along the green trail before it reopens to the public again.West Midland Safari ParkThe latest attraction at the park is the new African Walking Trail. Opened in May, the trail features three viewpoints that allow visitors to see the park’s African animals on foot. There’s also a four-mile drive-through safari area with red panda, penguin and lorikeet areas. Groups of ten plus, arriving in the same vehicle, can save more than 40%.Knowsley Safari ParkThe five-mile safari drive through the site takes you past free roaming lions, rhinos and more than 100 cheeky baboons.

The 30-year-old owner of Gashora Farm knows what a difference that makes.“You need more role models,” he said, standing among knee-high rows of chilli (辣椒) plants. “If you have young farmers, they have land and they drive to the farm, others may think, ‘Why can’t I do that?’”Mr. Twahirwa, a university graduate, bought a friend’s tomato farm six years ago for $ 150. He made $ 1, 500 back in two months. “You have to link farming with entrepreneurship and real numbers,” he said.Many young Africans are abandoning areas in the countryside, choosing not to work hard and for a long time in fields — a job made tougher by climate change.But Twahirwa is one of the growing band of successful farmers working to make agriculture’s image on the continent more attractive. Some 1, 000 farmers now produce chillies for him. He is starting a fourth farm of his own, and exports fresh and dried chillies and oil to Britain, the United States, India and Kenya.Africa has the world’s youngest population and 65 percent uncultivated arable land (耕地后备资源).Yet accessing land and loans is difficult, and African productivity is low with crop yields just 56 percent of the international average.“Agriculture is mainly associated with suffering and no young person wants to suffer,” said Tamara Kaunda. She believes African agriculture needs a change to get rid of its old-fashioned image of very hard and tiring work with a hoe. “Show young people with tractors, green fields, nice irrigation systems smartphones,” she said.Getting young people involved in agriculture does not mean they have to work on a farm. For example, in coffee production, the beans go from the farm to the washing station , then to be separated from the husks (外壳).14．What does “Why can’t I do that?” in Paragraph 2 mean?B．Why can’t they farm?C．They follow the example of those farmers.D．They bought a friend’s tomato farm.15．What makes it harder for farmers to work?A．Poor land.B．Climate.C．Low income.D．Long working hours.16．What can we learn about Twahirwa according to Paragraph 5 ?A．He made a fortune by growing chillies.B．His chillies are try growing chillies.C．Farmers working for him live a simple life.D．The locals aren't willing to buy his chillies.17．When it comes to agriculture in Africa, what do people think about it?A．Loans are difficult.B．Most land is uncultivated.C．Crop yields are rather lowD．Farming methods are out of dateAt the foot of an Icelandic volcano, a newly-opened plant is taking CO₂ from the air and turning it to rock. This technology is known as “direct air capture(捕捉)” or DAC．It’s a bit like “mining” the sky for CO₂—simple in principle, but very difficult to carry out.To do this, you need the right geography conditions. That is why Climeworks, a Swiss company, built the Orca plant in Iceland. There, fans draw air into big black containers where the filter(过滤器) catches CO₂. Once the filter is full, it is heated to around 100₂ to separate CO₂ with sufficient energy from volcanic activity. Next, the collected CO₂ is combined with water and pumped deep underground into rock formations. Within a few years, the CO₂ will turn into stone.However, exciting and promising as this technology is, it won’t save us from climate change on its own. While Orca, the largest plant of its kind in the world, can capture up to 4,000 tons of CO₂ per year, the yearly global emissions(排放) are around 33.4 billion tons ofexpensive and requires large amounts of energy.Daniel Egger, the chief commercial officer at Climeworks, said that while his company is at an “industrial level”, it is not where it needs to be to make a difference in fighting climate change. But we have to learn to walk before we can run.Carbon storage(碳储存) is just arising as a technology. It won’t help us fix climate change yet, but it can be important down the line, if we have the right conditions for it. 18．What can we learn about DAC according to the text?A．It is the best way to fix climate change at present.B．It requires enough heat and energy to operate.C．It is highly developed in removing CO₂.D．It can be applied anywhere in the world.19．Why are some data used in paragraph 3?A．To indicate the bright future of the technology.B．To provide the research results for the readers.C．To show the challenges DAC faces at present.D．To call for more plants like Orca to be set up.20．What is the author’s attitude towards the technology?A．Unclear.B．Uninterested.C．Doubtful.D．Hopeful.21．From which is the text probably taken?A．A science report.B．A company leaflet.C．A chemistry textbook.D．A social web page.Mirroring body language is a way to bond and to build understanding. It is a powerful tool that we use without even knowing it.The most obvious forms of mirroring are yawning and smiling. When you see someone yawn, you are likely to yawn immediately. Smiling is also pretty contagious—seeing aMirroring body language is a nonverbal way to say “I am like you or I feel the same”. Research shows that people who experience the same feelings are likely to trust, understand and accept each other. Women have the natural ability to pick up and understand body signals. Therefore, it is not surprising that a woman is more likely to mirror another woman than a man is to mirror another man.That’s why women are regarded as better talkers, even if they might not really have more close friends.Mirroring body language is an excellent way to build trust and understanding quickly. If you want to set up a connection with others, mirror their gestures, sitting position, tone of voice and talking pace. This will make them feel that there is something about you that they like.While mirroring body language gains you acceptance, you still need to take into consideration your relationship with the person you are mirroring. If you are in a lower social position and are mirroring the body language of your boss, he will view you as rude. However, if you want to defeat those who are trying to prove superior to you, mirroring their body language will help defeat them and change their position.22．What does the underlined word “contagious” in paragraph 2 mean?A．Affecting each other.B．Showing one’s feelings.C．Attractive to the others.D．Gentle to people around.23．What can we know about women from the research?A．They don’t like mirroring others.B．They tend to have more close friends.C．They are naturally gifted in building trust.D．They are good at interpreting body language.24．What is the author’s attitude to the behavior of mirroring the boss?A．Indifferent.B．Curious.C．Doubtful.D．Disapproving. 25．What is the best title for the text?A．The Common Forms of MirroringB．The Excellent Method of MirroringC．Mirroring Body Language:A Useful ToolD．Nonverbal Communication:A Special BondMuch of the work in today’s world is accomplished(完成) in teams. Most people believeCompanies spend millions hiring top business people. Is their money well spent?27 They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent; above that level, the team’s performance begins to decline. Interestingly, this trend isn’t evident in baseball, where additional individual talent keeps improving the team’s performance.To explain this phenomenon, the researchers explored the degree to which a good performance by a team requires its members to coordinate(协调) their actions. 28 In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, for example, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team’s performance. Young children learning to play team sports are often told, “There is no I in TEAM.” 29Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tug-of-war(拔河比赛), whenever a person is added, everyone else pulls the rope with less force.30 An A-team may require a balance--not just A players, but a few generous B players as well.A．It’s not a simple matter to determine the nature of talent.B．Sports team owners spend millions of dollars attracting top talent.C．The group interaction and its effect drew the researchers’ attention.D．Stars apparently do not follow this basic principle of sportsmanship.E．Several recent studies examined the role of talent in the sports world.F．Building up a dream team is more complex than simply hiring the best talent.G．This task interdependence distinguishes baseball from football and basketball.William ThomsonWilliam Thomson was born on 26 June, 1824 in Belfast. He was taught by his father, a professor of mathematics. In 1832, the family moved to Glasgow where Thomson attended university at the age of 10, then studied at Cambridge and Paris Universities. In 1846 he became professor of natural philosophy in Glasgow, a post he 31 for more than 50 years.In Glasgow, Thomson 32 the first physics laboratory in Britain. He was a pioneer in many different 33 , particularly electromagnetism (电磁学) and thermodynamics (热力学). 34 Faraday(法拉第), he was responsible for the introduction of the 35 of an electromagnetic field where Thomson developed the work of the 36 of the subject, Nicolas Carnot and James Joule. One of the most 37 results of his work was his idea of an absolute zero of temperature — the scale based on this is named 38 him.Throughout his work Thomson’s main goal was the practical use of science. He achieved39 through his work on submarine telegraphy, a major practical problem of the day. He was40 as a scientific adviser in the laying of the Atlantic telegraph cables in 1857-1858 and 1865-1866,for which he was knighted in 1866. His 41 in marine issues also inspired him to develop a mariners’ compass and 42 a tide machine and depth-measuring equipment.

UK physicist Isaac Newton once said, “Nature is pleased with simplicity and nature is no dummy.” Indeed, Mother Nature 1 provide almost everything human beings need if we follow her rules. 2 if we break the rules, she is likely to be cruel and punish us.3 outbreak of the COVID-19 in China and some4 countries at the beginning of this year is an example. According to Xinhua News Agency, the new coronavirus is similar5 a virus found in a bat in 2017.

For example, the American Indians believed 8 humans are part of nature and nature is part of humans. Chinese ancients always pursued the harmony between nature and human beings. However, as human beings get more knowledge and make more advanced tools,people try to change and even control nature. They use more land 9 buildings, capture some wild and rare animals to meet their own needs. In this process, humans 10 lose contact with nature and even throw it out of 11 . For example, cutting a large number of forests12 carbon dioxide must build up in the atmosphere and it leads to global warming.13 we don't know for sure what first caused the COVID-19 outbreak, it's time for people to think about our relationship with our planet and everything 14 we've been given.

He came up with the idea after he dropped his daughter off at college in upstate New York. The school had about a dozen professors giving short talks about a variety of subjects. All the parents had the same reaction: “I wish I were the one going to college!”One Day University creates fascinating days of learning designed to inspire your mind.

I remember as if it were yesterday, hearing her voice at my side on a cold wintry night. My mother’s voice changed my world.Long before I could read on my own, she shared with me the strength and beauty of McCloskey’s language, a story of a little girl and her mother out in nature, co-existing with a mother bear and her own baby. The power of the story, of language and of my mother all came together. And it happened many times after that, over and over. The reading aloud made me a reader.Years later, I was reading aloud a picture book to a small child in a classroom. His life, so far, had not been easy. His childhood was troubled by poverty and loneliness. In that moment, in the joy of reading aloud, he had an idea that started something big.What he said was this: “Mrs. Allyn, let’s make sure everyone knows how good this feels. Let’s have a holiday for reading aloud.” Therefore, my organization, Lit World, created a grassroots movement World Read Aloud Day in 2010 to honor this young boy’s wish for everyone to be able to have a reading aloud every day.Since the day he shared that good idea with us, World Read Aloud Day has become a worldwide event reaching over one million people in more than 65 countries around the world. This year we are over 600 cities strong, a number that is growing every day.Children who grow up as readers become engaged citizens of the global world, and every child deserves the right to read. When I say that reading aloud will change the world, I know it sounds simple. But one of the many great things about giving kids access to the power of stories and sharing them together is that it is simple. It is also cheap and easily done. And the impact is huge.19．How did the author’s parent change her life?A．By reading aloud to her.B．By listening to her reading.C．By buying many books for her.D．By encouraging her to read aloud. 20．What was the small child’s idea in Paragraph 3?A．To start a holiday.B．To reduce poverty.C．To found Lit World.D．To overcome loneliness.21．What can we know about World Read Aloud Day from Paragraph 5?A．Its origin.B．Its future.C．Its purpose.D．Its development.22．Which would the author most probably agree with according to the passage? A．Sticking to reading isn’t easy.B．Reading gives a high rate of return.C．Reading aloud can remove loneliness.D．Kids should try to change the world.Humans have been exploring the infinite abyss (深渊) beyond Earth’s atmosphere. When astronauts explore the vast expanse of outer space, they need to wear high-tech spacesuits to protect them from the freezing conditions of the universe.Hollywood movies have idealized the iconic suit, its design leading the masses to believe it’s an outfit that can be slipped on within minutes. In fact, the spacesuit which is made up of nearly a half dozen different components and can have up to 16 layers is its own fully functioning spacecraft that takes hours to put on and requires help from one’s colleagues.The astronauts on the Artemis missions, NASA’s next program to send the first woman and the first person of color to the moon, will wear the latest spacesuit, called the exploration extravehicular mobility unit, also known as xEMU, according to NASA．Each spacesuit has a portable life support system, which includes a water tank for the cooling garment and carbon dioxide removal system to regulate body temperature, remove excess heat and maintain the astronauts’ health, said Richard Rhodes, the deputy lead for xEMU pressure garment development at NASA．A two-way radio system is also included so the astronauts can communicate during the missions.“When the Apollo astronauts walked on the moon, they couldn’t bend over and pick up a rock,” said NASA astronaut Mike Fincke. Fortunately, spacesuits have come a long way sincethen and have a more flexible structure with gloves. The gloves are one of the most complicated parts of the spacesuit, said Cathleen Lewis, curator of the Smithsonian Institution’s National Air and Space Museum. “Gloves are very difficult to design to be protective and also allow the manual flexibility that astronauts need to do meaningful work.” she noted.The spacesuits will also be getting some upgrades for the latest lunar mission. Richard Rhodes’s team is working on the spacesuit that will allow for more movement to explore the rough terrain of the moon while still being strong enough to protect the wearer.23．What can we learn about the spacesuit in Hollywood movies?A．It provides the most ideal design.B．It functions as a spacecraft of its own.C．It can be put on without too much difficulty.D．It has larger mass than real-life spacesuits.24．In what aspect does Paragraph 4 mainly talk about the latest spacesuit?A．Its cooling garment.B．Its main parts.C．Its existing problems.D．Its initial aims.25．Why are the Apollo astronauts mentioned in the passage?A．To contrast the Apollo spacesuit with the latest one.B．To give an example of a successful space mission.C．To demonstrate the difficulty of the Apollo missions.D．To highlight the incompetence of the Apollo astronauts.26．Which of the following best describes NASA’s spacesuit for the next lunar mission? A．High-tech but impractical.B．Portable and mobile.C．Costly but well-received.D．Flexible and protective.A 1930s-ancient restaurant in my town has done little to update itself over the past 80 years. This is part of its charm, as is the wooden phone booth(亭)sitting neglected in the age of the cellphone. And we need it now more than ever.For me it symbolizes that phone calls were once private affairs, even if the information being shared was not sensitive. In public places this meant resorting to the phone booth—a private space where one could converse in peace without being overheard.When I grew up in the 1960s, phone calls used to be regarded as something private, evenat home. However, within the space of very few years, private conversations have become public broadcasts, and being overheard seems to be the point. The problem, of course, is that we now carry our phones with us and answer the device as soon as it rings, but at the price of our privacy being disclosed!Not long ago I was sitting in Boston’s South Station, waiting for my train while a man was on his cellphone. I silently recited every detail of his phone conversation including his card number and its password. I stared at the fellow. He glanced at me, asking, “What?” My immediate respons: Reciting all I had overheard to him, which left him opening his eyes wide.There is no more privacy, no longer a sense of personal borders or limits. The cellphone has become a megaphone, making our privacy known so easily to others.To return to phone booths: Why did they disappear? They used to be everywhere in my childhood and can readily serve as cellphone shelters today. A Mr. Riley had one in his small, struggling candy store where I grew up. Even at the age of 9, before I had acquired any life experiences, I would have labeled “private”, I would sometimes separate myself from my friends, close its door, and call home in peace and quiet.Should you think a phone booth has no value today, I saw one on eBay going for $ 4,750.And Mr. Riley would have flipped.27．How does the author support the theme of the passage?A．By listing various reasons.B．By comparing differences.C．By sharing his own experiences.D．By proving study results.28．What is the underlined word “megaphone” in Para 5?A．An earphone.B．A loudspeaker.C．A mobile phone.D．A calculator.29．What does the author really indicate when referring to the old phone booth?A．The place the old phone booth holds.B．The good interpersonal relationships.C．The money value of the old-fashioned booth.D．The privacy boundaries people should keep.30．What can be the best title of the passage?A．My Story of Old Phone BoothsB．Does Privacy Still Matter Now?C．The Return of the Old Phone BoothD．Old Phone Booths, Still Valuable?三、七选五How do you feel about bees? Do you get annoyed when they fly around you and do you fear their mission is just to sting (叮) you? 31 Without them, we might starve (饿死).Bees deserve some respect. They give us honey, and they play their part either pollinating (授粉) the many vegetables and fruits we eat directly or pollinating the food for the animals that we then consume. 32 That’s not all — a study in the UK, found bees and other pollinating insects have a global economic value of around £120bn ($150bn) and contribute around £690m ($850m) to the UK economy every year. So, bees are worth protecting.33 But experts say we should be taking care of all our bees. Researchers say conservation efforts should be aimed at a wide number of species — even those that currently contribute little to crop pollination — in order to maintain biodiversity and ensure future food security. 34 It’s something we should be worried about because, as Gill Perkins, chief executive of the Bumblebee Conservation Trust, said, “They provide a whole ecosystem service.” The recent lockdowns caused by the coronavirus pandemic (流行病) seem to have given bee populations a little boost because they faced less human disturbance, traffic and polluting fumes.Conservationists hope, going forward, people will appreciate bees more and encourage them to do well as they reconnect with nature. Gill Perkins says, “They are beginning to realise how their mental health and wellbeing is supported by nature — particularly by bumblebees (大黄蜂), which are so beautiful and buzzy.” 35A．A small number of bee species are essential for crops such as apples and strawberries.B．The bees busied themselves at making honey.C．So, it really seems time to give bees a second chance.D．In fact, they are the world’s most important pollinators.E．The words remind people of this saying “honey is sweet but the bee stings”.F．Love them or dislike them, these little insects are extremely important creatures.G．Unfortunately, in recent times, bee populations have been declining due to pesticides, disease and habitat loss.四、完形填空Growing up, I knew one thing about my accountant father: he understood everything. Inwondered at times if maybe he had already 41 everything I needed to know.This past summer, I moved in with my parents while our house was being repaired. Dad asked me to help him 42 the bulkhead (舱壁) at their dock. As we put the new bulkhead together piece by piece, my dad knowing 43 what went where, I looked at him. “How do you know how to build a bulkhead?” “I spent a summer in college building them.” “You did?” I thought I knew everything about my dad—all his 44 jobs. I knew about him being the apple collector, the TV repairer. But I never knew this. “Yep. Now let me teach you how to use this saw (锯子). As he explained the 45 , I realized that maybe it’s not that there’s nothing left to say. Maybe it’s just that I’ve spent my life asking him the 46 questions.After I moved back, I called my parents. Dad answered. “Hi, sweets”. Here’s Mom.” “ 47 Dad.” I said. “How are you?” We 48 talking about work he was doing. To anyone else, it would sound like a 49 conversation between a dad and his daughter. But to me, it was a new 50 . I spent the first part of my life needing to talk to my dad.

In fact, he was so excited that he didn’t even need the alarm clock to wake him. He practically jumped out of bed and put on his new clothes. Then he sat down to a delicious breakfast that Moan had made. It included all his favorites—orange juice, toast with strawberry jam and sausage.When he finished eating, Louis grabbed his baseball cap and his backpack, and he waved good-bye to Mom.“Have a wonderful first day at school, Louis!” she called after him.As soon as Louis opened the door and stepped out, huge drops of rain suddenly started falling. Louis looked up and was surprised to see grey clouds covering the entire sky. The weather forecast had been for a beautiful, sunny day but it was raining outside! Louis quickly came back inside the house.Louis needed to do something at once, because the school bus was going to arrive any minute. Louis patiently tried to think of what he could do. Then he put on his raincoat and rain boots and took his umbrella.Then Louts headed out the door again. He wouldn’t let anything else ruin (毁坏) his first day of school. He carefully walked to the corner where he waited for the school bus. Within minutes, the big yellow bus drove up. As it was coming to a stop, the bus went through a huge puddle and splashed the water right on Louis!Louis could have been upset about this accident, but instead he put on a smile. “Thanks for waking me up with a splash!” he said to the bus driver. “It’s a good thing I was wearing my raincoat.”Most people would have thought that the day was off to an awful start. It might have been enough to put anyone in a bad mood, but Louis is not like most people! He remained cheerful and upbeat. He still loved the first day of school, and he was certain that exciting things were still going to happen on this day.26．What did Louis NOT have for breakfast?A．Toast with jam.B．Orange juice.C．Eggs.D．Sausage. 27．According to the weather forecast, it is expected to be a ________ day on Monday.

Athletes from only 13 countries took part in the Games that year. They competed in 43 different events in just 9 sports (track and field, swimming, cycling, fencing, gymnastics, shooting, tennis, weight lifting, and wrestling). In 2004, the summer Olympic Games took place once again in Athens, Greece. This time athletes from 202 countries competed in 300 events in 28 sports.Only five sports have been in every Olympic Games. They are track and field, swimming, fencing, cycling, and gymnastics. Other sports come and go in the Olympic Games. For example, tennis was an Olympic sport from 1896 until 1924. It was a hit among the athletes all over the world when it first appeared. However, it did not appear in theOlympics until 1988. Baseball, badminton, and taekwondo are more recent additions to the Olympic Games.It is the job of the International Olympic Committee (IOC) to add and remove sports from the Olympic Games. A sport has to be popular in at least 50 countries on three continents before it can be added. However, the IOC doesn’t want to add more sports to the Olympic Games without eliminating (消除) others. The IOC is afraid that there will be too many sports in the Olympics.Artistic events were also a part of the Olympic Games from 1912 to 1948. There were contests in architecture, music, literature, and painting. Today some people think that artistic events and games such as chess should be part of the Olympics. However, many people oppose this idea.The Olympic Games today are different from the first modern Olympic Games in 1896. These differences lead to the changing definition and popularity of sports.30．What is TRUE about the first modern Olympic Games?A．The first modern Olympic Games was held in Rome in 1896.B．Only 13 athletes from different countries took part in the Games.C．There were forty-three different events for athletes to compete.D．Swimming wasn’t one of the sports in the first modern Olympics.31．What does the underlined word “oppose” in Paragraph 4 mean?A．are certain about B．disagree with C．are happy with D．feel ashamed of 32．In which order did the fallowing events take place?a. Tennis became an Olympic sport for the second time.b. Artistic events became a part of the Olympic Games.c. Athletes from 202 countries competed in 300 events.d. Tennis disappeared from the Olympic Games.e. The first modern Olympic Games took place.A．e-c-d-a-b B．e-b-d-a-c C．c-e-b-d-a D．c-a-e-d-b 33．The purpose of the passage is to introduce ________.A．how sports come and go in the Olympic GamesB．who adds and removes sports from the Olympic GamesC．which sports are popular in modern Olympic GamesD．why some sports events were a part of Olympic GamesDo you want to improve your physics and chemistry grades? Well, maybe you should first learn something about the struggles (斗争) of great scientists.The American Psychological Association (美国心理学会) did a study. More than 400 students in New York City took part in it. The students were divided into three groups. Group 1 read a typical textbook that describes the achievements of great Scientists. Group 2 read about those scientists personal struggles. For example, as a Jew, Einstein escaped from Nazi Germany to avoid being killed. Group 3 read about the scientists’ intellectual (智力的) struggles, such as Marie Curie’s tailed experiments. These stories about struggles also told students how the scientists dealt with these problems.The students took a science test before the study. After the six-week study, they took another. Scientists found those in Groups 2 and 3 improved their science grades. Students in Group 1 didn’t see a grade increase. Some of them even had lower grades after the study.The study was led by Xiaodong Lin Siegler, a professor. According to Xiaodong, kids often think Einstein was born a genius. They believe they will never match him. Many of them fail to realize that any success requires a long journey. Along the way, there are many failures.Students who read the struggle stories were more likely to say great scientists were like themselves. The “great minds” also had to solve problems to achieve success.Xiaodong says today’s science textbooks fail to bring science to life. As a result, students hardly consider science as part of their everyday lives. Instead, they just see a long list of facts that they have to remember. Xiaodong thinks textbooks should include more stories about how great scientists had to struggle to succeed. And they should pay more attention to how these scientists responded to the problems they met along the way.34．According to the passage, we can improve our physics and chemistry grades by________.A．reading the achievements of great scientists more carefullyB．listening more carefully to our physics and chemistry teachersC．learning about the difficulties that great scientists once experiencedD．spending more time remembering the lists of facts in our science textbooks35．Who took part in the study held by the American Psychological Association? A．Students who went to schools in New York City.38．Which sleeping position often causes lower back pain?A．Starfish.B．Soldier Position.C．Sleeping on Your Belly.D．Freefall. 39．Sleeping in the soldier position helps ________.A．you fall asleep quickly B．keep your spine in a straight line C．you breathe easily D．treat the pain in your neck 40．According to the passage, which of the following picture should probably be a Freefall position?A．B．C．D．四、阅读还原5选5阅读短文及文后A～E选项，选出可以填入1～5各题空白处的最佳选项。
