In San Francisco, “the center of tech”, 40% of older adults do not have basic digital literacy skills.This situation is becoming appalling as over 10,000 Americans turn 65 every single day. By 2050,22% of Americans will be 65 or older. Meanwhile, technology is developing very fast. This means that a large number of people will be unable to proficiently use emergent technology.Many people believe that seniors aren’t required to participate in our tech future because they’ll be retired and relaxed soon. But this is the farthest thing from the truth. Baby boomers are currently experiencing a different boom: With more people getting older than ever before, their life expediencies are also increasing dramatically. With medical advancements, the number of American people projected to live into the ir 90’s has doubled since 1965.However, they don’t have strong financial or educational support. This is not a problem; it’s a crisis. More than half of employees over 50 have been laid off in what’s being called ”forced retirement“. And few organizations are actively helping older employees make the transition from full-time jobs to part-time ones. For those fortunate enough to be employed, 3 out of 5 older workers experience prejudice.The easiest solution is to teach digital literacy. If baby boomers want to survive the forthcoming retirement crisis, they should get enough digital knowledge and skills to operate today’s tools and tomorrow’s platforms. With every crisis comes an opportunity. Tutoring, customer service, editing, research, book-keeping, and other virtual assistance-based work open the doors. But again, digital knowledge is first required to live in our high-tech society and gig economy. So try to get more online and navigate the growing number of sites and apps.；4. What does the underline d word “appalling” probably mean in paragraph2? A．Confusing. B．Terrible. C．Controllable. D．Inspiring.；5. What problem may baby boomers face?A．A crisis after retirement. B．Being knocked out in the future. C．Failing to receive good healthcare. D．Tending to double their life expediencies.；6. What is the last paragraph mainly about?A．The features of high-tech jobs. B．The way out for baby boomers. C．Potential industries in the future. D．The importance of developing technology.；7. What does the author advise baby boomers to do?A．Have a good sense of crisis. B．Avoid retiring at an early age. C．Look for many part-time jobs. D．Improve digital literacy actively.CGrowing up as kids we are told to share our toys and not to be selfish. We also live in an age when discussing our feelings is encouraged. But when does it all become toomuch? With new crazes trending all the time, such as dance challenges and wearing a carpet as a dress, the question is: when can sharing become oversharing on social media?“Oversharing” has become associated with social media, but it isn't exclusive to this platform. Imagine you head to a party and meet x k w someone. Within five minutes they have revealed private details about their life. While some of us may try to escape these people, according to marriage advisor Carolyn Cole, this form of oversharing could come from a strong desire to connect with someone. But how does this translate to social media?Dr. Christopher Hand, a lecturer in cyberpsychology (网络心理学），says the more details people disclose, the less sympathy we express when things go wrong. It seems that searching for sympathy by oversharing is generally considered as negative rather than the cry for help it could really be.However, Dr. Hand's research also seems to suggest that the more we post on a platform, the more socially attractive we become-provided that the posts that we bang out are positive. Even back in 2015, Gwendolyn Seidman PhD said that we should avoid complaining and being negative online. We should also avo id showing off, especially about our love lives. It makes sense-if your date is going “that well", would you really have time to share a photo with text?So, how can you know if you are oversharing? Well, why not ask your friends in real life. They would probably be happy to tell you if your posts about your breakfast or your complaints about your lack of money really are too much.；8. What does the underlined word “exclusive" in paragraph 2 mean?A．Unique.B．Similar.C．Relevant.D．Fundamental.；9. Why do some people prefer oversharing at parties?A．To draw others' attention.B．To satisfy others' curiosity.C．To remove negative feelings.D．To develop good relationships.；10. Which of the following may Dr. Hand agree with?A．Sharing more details online can attract more sympathy.B．Oversharing negative experiences is equal to crying for help.C．Sharing negative posts can't help one become socially attractive.D．Oversharing isn't likely to happen online when things go wrong.；11. According to the text, what should be avoided for online sharing?A．Reflecting on past bad manners.B．Showing a great many expensive goods.C．Writing a recipe for a balanced breakfast.D．Recording unforgettable moments with friends.二、七选五阅读For most Americans, the weeks between Thanks giving and New Year’s Day are a time when we’re eating more than we should. 12 The problem wasn’t really thesmall weight increase but that study participants never lost what they put on during the holiday season.So, how do you avoid gaining weight without missing out on the holiday fun? There are several small changes we can make.We have to make time to exercise. With all the shopping that needs to be done and the holiday get-togethers, the first thing cut out of our schedules is often exercise. 13 Exercise not only burns off those holiday treats, it reduces our stress as well.14 Allow yourself to enjoy the foods you really love, but choose wisely and watch your portion (份额) size. If you’ve looked forward to Aunt Sally’s Christmas cookies all year, have one. Mindful eating is the key. Take a small portion of your favorite dessert or high-calorie dish and then enjoy it.Try never to go to a holiday celebration hungry. When you are really hungry, you tend to eat more than you normally would. 15 Then you’ll find it easier to control how much you eat.Weigh yourself at least once a week on the same day, at the same time and on the same scale (称). It’s important to keep in mind that our weight can change because of salt intake or other factors. 16A．Mind your table manners while eating.B．You don’t need to give up all of the holiday goodies.C．However, knowing your weight helps to keep you on track.D．Have a high-fiber, low-calorie snack before attending a party.E．A study found participants gained just over a pound during this time.F．Instead, this is the time we should put working out at the top of our to-do list. G．Researchers suggest people eat smaller meals more times during the course of the day.三、完型填空Sammie Vance approached her principal at Haley Elementary with the idea of installing “buddy benches” into her school playground to help others feel less lonely.

In a special school for the hearing-impaired（听觉受损的）, he learned sign language and got to mix with other disabled children, However, the sight of all the disabled children communicating with one another upset his mother. She wanted him to lead a normal life. So after speaking to an advisor,she sent him to private classes where he learned to read lips and pronounce words. Later on, Adrian’s parents decided to send him to a regular school. But the headmaster tried to prevent them from doing so,saying regular schools couldn't take care of a special needs student.His parents were determined to take the risk and pushed him hard to go through his work every day because they wanted to prove that,given the opportunity, he could do anything.Adrian made the grade and got accepted. It was a big challenge.The pace（节奏）was faster so he had to sit at the front of the class and really pay attention to the teacher, which wasn’t always easy. But he stuck to it and did a lot of extra work after school.The efforts made by Adrian and his parents paid off. Adrian graduated with good grades and got into a lop high school.He also achieved a lot in life outside school.He developed a love for the outdoors and went to Nepal to climb mountains.He even entered the World Yacht Race 05/06-being the first hearing-impaired Asian to do so.But none of these achievements would have been possible without one of the most important lessons from his mother. “If you believe in yourself and work hand, you can achieve great results.” She often said.4.How did Adrian communicate with other children in the special school?A.

He took part in the World Yacht Race 05/06.CUsing too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways.You may wonder how paving（铺砌）amad can lead to less useable fresh water,A major part of the water we use every day is groundwater.Groundwater does not come from lakes or rivers.It comes from underground.The more roads and parking lots we pave the less water can flow into the ground to become groundwater. Human activity is not responsible for all water shortages. Drier climates are of course more likely to have droughts（干旱）than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number.You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day.Run your dishwasher（洗碗机）only when it is full. Help your parents fix any leaks in your home.You can even help to keep our water supply clean by recycling batteries instead of throwing them away.8.Which of the following is most likely to lead to less groundwater?ing river water.B.Throwing batteries away.C. Paving parking lots.D.Throwing rubbish into lakes.9. What can be inferred about the water supply from the text?A. All water shortages are due to human behavior.A.To tell us how to run a dishwasher.B. To show us how to fix leaks at home.C.To prove what drinking glass is best for us.D. To suggest what we do to save water at home.11.What is the text mainly about?A. Why paving roads reduces our water.B. How much we depend on water to live.C. Why droughts occur more in dry climates.D. How human activity affects our water supply.DAnimals can move from place to place,but plants cannot.When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws.But plants can defend themselves by using both physical and chemical means.Some plants have their own ways to keep animals away.For example,the leaves of the holly plant have sharp sines刺）that discourage grass-eating animals.Holly leaves on lower branches have more spines than leaves on upper branches.This is because the lower leaves are easier for most animals to reach.Some plants, such as the oak tree,have thick and hard leaves that are difficult for animals to reach. grasses may contain a sandy material; eating such grasses wears down the animal’s teeth.Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction.Some plants may fight against an attack by increasing the production of these chemicals.When a caterpillar（毛虫）bites a tobacco leaf，the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine.The higher levels of nicotine discourage the caterpillar.Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has -prickly（多刺的）leave, and catch pricklecontains poisonous venom.A single experience with this kind of plant will teach an animal to stay away from it in the future.12.Why does the holly plant have more spines on the lower leaves?A. Most animals are not tall enough.B. Most animals are not clever enough.C.Most animals like the lower leaves only.D.Most animals can gel the lower leaves easily.13. What do oak trees use to defend themselves?A. Chemical means. B Physical means.C.Bitter chemicals.D.Sandy materials.14. How does tobacco protect itself against an attack from a caterpillar?A.Its leaves fight against the attack by physical means.B. Its roots send a messenger to discourage the caterpillar.C. Its roots increase the production of nicotine when it is attacked.D.Its leaves produce poisonous sand to drive the caterpillar away.15. What is the best title for the text?A. Plants and AnimalsB. Attacks and DefensesC. How Animals Eat Plant LeavesD.How Plants Defend Themselves第二节（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。

It does, however, have its own problem.Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rulesrequire that a race walker’s knees stay straight through most of theleg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such anattractive activity, however, says Jaclyn Norberg, an assistantprofessor of exercise science at Salem State University in Salem, Mass.Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon amo ng race walkers. But thesport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to becautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.4. Why are race walkers conditioned athletes?A．They must run long distances.B．They are qualified for the marathon.C．They have to follow special rules.D．They are good at swinging their legs.5. What advantage does race walking have over running?A．It’s more popular at the Olympics.B．It’s less challenging physically.C．It’s more effective in body building.D．It’s less likely to cause knee injuries.6. What is Dr. Norberg’s suggestion for someone trying race walking? A．Getting experts’ opinions.B．Having a medical checkup.C．Hiring an experienced coach.D．Doing regular exercises.7. Which word best describes the author’s attitude to race walking? A．Skeptical. B．Objective.C．Tolerant. D．Conservative.CAn unconventional method for growing rice has been found to increase yields(产量) by 20 to 50 percent. Reports from China, India, Southeast Asia and Africa suggest that average yield increases of 20 to 50 percent are regularly being achieved by farmers adopting the "system of rice intensification(集约化)"(SRI)，which needs one-tenth as many seeds and aims to stimulate the root system of plants rather than trying to increase yields in the conventional way by using improved seeds and fertilizers.The idea of using less to gain more is seen as an important innovation(革新) for adapting farming to climate change and a way to increase yields at a time when human populations are growing fast but traditional plant breeding and genetically modified techniques have failed to increase yields more than a few percentage points, says Norman Uphoff, professor of international agriculture at Cornell.The new way to grow rice needs only half as much water, and is proving most popular in water-stressed countries, says Tavseef Mairaj Shah, a Ph.D．researcher. "Rice growing in Kashmir largely depends on irrigation systems that draw water from the river Jhelum. But climate change is leading to drier winters, untimely rains, and warmer summers."“SRI is a great technique, not just from the water-savingperspective but because it offers better yields and soil conditions. Different studies, both at the experimental level and farmer-participative level, have shown that SRl improves yields with less water.” Shah adds.Some academic, the global seed industry and the international community once rejected reports of “fantastic” yields, accusingfarmers of falsifying(篡改）records and researchers of carelessness and "non-science". But more than 600 articles, checked by SRI Internationalat Cornell University, have shown benefits.Uphoff says, “Attitudes are changing.The original hostility(敌意)has gone." However, the early opposition has resulted in comparativelylittle scientific research being conducted into SRI and a slow understanding by funders.8. How does SRI increase the yields of rice?A．By sowing more seeds B．By using improved seeds.C．By improving its root system. D．By adopting special fertilizers. 9. Compared with the conventional method for growing rice, SRI.A．needs less water B．increases labor costsC．requires better soil conditions D．depends on genetically modified techniques10. What was the global seed industry's initial attitude toward reportson SRI?A．Curious B．Skeptical. C．Approving D．Uninterested. 11. Which of the following can be the best title of the passage?A．How to Increase YieldsB．People's Attitudes Towards SRIC．An Innovative Means of Growing RiceD．The Disadvantages of Conventional Plant Breeding二、完形填空A Florida man likes to shop at garage sales for old plaques(纪念匾)so he can reuse the wooden backs.

When people find I’m a polyglot(通晓多种语言的人)，they always ask me,“How do you do that?” Honestly, my answerwill be, “I don’t know. I simply love learning languages.” 32 They want to know why they spend years learning even one language, never achieving fluency, and what’s the secret of being polyglots.33 And what do we have in common? I decided to find that out. I went to several events where language lovers gather to practice their languages, asked dozens of polyglots about methods they use, and heard dozens of approaches. Everybody seems to have a unique way to speak several languages fluently.34 All these polyglots talked about language learning as if it was great fun. They found ways to turn language learning from aboring subject into a pleasant daily activity. You should have seentheir faces when they were showing me their colorful grammar charts and handmade flash cards. 35 The methods are various, but they make sure it’s something enjoyable.I realized it’s actually how I learn. 36 Then interesting programs became my choice. So all is clear. If you don’t like writing words down on paper, type them in an app. If you’re a shy perso n, apply self-talk at home. This is how polyglots learn languages, and the best news is that it’s available to anyone willing to take the learning into their own hands.A．How can those with little talent be fluent?B．But people are never happy with the reply.C．There’s no shortcut to learning languages for anyone.D．One of them even made recipes in a foreign language.E．That made me wonder, too, how other polyglots actually do it. F．When learning Spanish last year, I was bored with textbooks. G．Polyglots simply found ways to enjoy the language-learning process.四、语法填空阅读下面短文, 在空白处填人1个适当的单词或括号内单词的正确形式.May 21st this year marks the first International Tea Day, which37 (name) by the United Nations on November 27th, 2019.

They have developed a very thin and gold-based transparent coating (涂层) that can convert sunlight into heat, which can be applied to glass and other surfaces to prevent them from fogging.The special coating is developed using titanium oxide and gold particles. It selectively absorbs infrared radiations (红外线照射) from the sunlight and creates a heating effect that is powerful enough to keep fog away from the surface of an object.The coating basically employs heat to stop fogging. The coating absorbs a large part of the infrared radiation, which causes it to heat up-by up to 8℃.Previously, products like anti-fogging sprays create a very thin film of water on the surface to remove fog. The problem with such surfaces is pollution. Along with water, the sprays also attract dirt, dust, oil, and various other dirty substances, and just a little dirt on the surface makes it useless. However, the new coating repels (排斥) water. Furthermore, the coating is significantly thinner, which makes it more transparent as well as flexible. It is heated passively and requires, during daytime, no additional energy source.Gold might be expensive, but the researchers stress that their coating requires solittle that the material costs remain low. Their coating is produced with standardized and readily scalable methods, all cost-effectively. However, although this product can work at very low levels of solar irradiation, it does rely on a certain amount of light.The researchers will develop the coating further for other applications. In the process, they will examine whether other metals work just as well as gold. There is no need to fear. However, this would cause a car or a building to heat up more in the summer. The researchers have already filed a patent. Hopefully, this groundbreaking product will soon be available on the market.；4. How does the new coating work to remove fog?A．By reflecting part of sunlight selectively.B．By keeping cool air away from the object.C．By creating a thin film of water on the surface.D．By absorbing infrared radiations to heat the coating.；5. Why does the author mention previous anti-fogging products?A．To stress the advantages of the new coating.B．To introduce the inspiration behind the new coating.C．To prove the difficulty of creating anti-fogging products.D．To explain the reason for the anti-fogging coating being popular .；6. What is the limitation of the new coating?A．It is considerably expensive.B．It depends on sunlight to work.C．It takes too much time to produce.D．It is difficult to clean and maintain.；7. What do the researchers plan to do next?A．Apply for a patent for the invention.B．Develop the product for more practical uses.C．Explore the environmental impact of the coating.D．Seek a cheaper material as an alternative to gold.CAn exhibition of vivid photographs and a restored documentary give fresh insight into the Antarctic explorer, who died a century ago.One hundred years ago, the leader of the last great expeditio n of the heroic age of polar exploration died from a heart attack as his ship, Quest, headed for Antarctica. The announcement of the death of Ernest Shackleton on 30 January 1922 was greeted with an outpouring of national grief.This was the man, after all, who had saved the entire crew of his ship Endurance —which had been crushed and sunk by ice in 1915 — by making a daring trip in a tiny open boat over 750 miles of polar sea to raise the alarm at a whaling station in South Georgia.It remains one of the greatest rescue stories of modern history and led to the idolising of Shackleton in the United Kingdom, a reputation that survived undamaged for the rest of the century. As his contemporary Raymond Priestley, the geologist and Antarctic explorer, later put it: “When disaster strikes and all hope is gone, get down on your knees and pray for Shackleton.”And here and now in 2022, his death is being marked with an elaborately illustrated exhibition —Shackleton’s legacy and the power of early Antarctic pho tography — which opens at the Royal Geographical Society (RGS), and which includes a range of images and artefacts from his expeditions. Additionally, a digitally remade version of South, a documentary film of Shackleton’s 1914-16 Endurance expedition, is being screened at the British Film Institute.The film and most of the exhibition’s finest images are the handiwork of Frank Hurley, who sailed with Shackleton and who was one of the 20th century’s greatest photographers and film-makers. Both film and exhibition feature striking camera work and provide vivid accounts of the hardships that Shackleton and his men endured as they headed off to explore Antarctica.Even after he survived the great expedition, he still longed for another trip to Antarctica, and after long negotiations set sail in Quest, from England, with the aim of circumnavigating (环航) Antarctica, Shackleton was by now very ill and had suffered at least one heart attack. On 2 January 1922, he wrote in his diary: “I grow old and tired but must a lways lead on.” Three days later he had a major heart attack and died a few hours later. He is buried on South Georgia, scene of his greatest triumph.“Shackleton was an inspirational leader. He had an innate sense of what was possible and achievable. He also had a huge personality but led by example. At the same time, he was sensitive to the needs of the individuals he was leading. For example, after Endurance broke up, his men had lost their protection and shelter. Their social fabric had been destroyed. There would have been disagreement. Yet Shackleton succeeded in keeping them together and made sure they survived.”8. People were overcome with grief when Ernest Shackleton died because .A．it was a huge pity that such a brave explorer should ha ve died from a heart attack B．he was the man that wrote about one of the greatest rescue stories of modern history C．he came to his entire crew’s rescue and symbolised hope in extreme circumstances D．there was no one to pray to anymore when disaster came and there was no hope9. What can we learn about the exhibition?A．It presents Shackleton’s 1914-16 Endurance expedition with powerful Antarctic photos.B．It celebrates the 100th anniversary of the great explorer Ernest Shackleton’s birth. C．It consists of vivid photographs, artefacts, and documentaries of Ernest Shackleton.D．It is created by Frank Hurley, who witnessed Shackleton’s heroic acts with his own eyes.10. Which of the following is NOT true about Ernest Shackleton according to the passage? A．He was the leader of a heroic exploration to the South pole, who died from a heart attack off shore.B．He saved the crew members of the sunken Endurance by travelling to raise the alarmin a tiny boat.C．He is universally recognised as the greatest Antarctic explorer who has enjoyed enduring fame.D．He was inspirational, practical, responsible, sensitive towards his men, but had a strong character.11. What does “Their social fabric had been destroyed. ” in the last paragraph most probably mean?A．What they wore would not be accepted by others upon returning.B．They could no longer socialise with others even if they went back.C．The ship could not keep them together even if they survived.D．They could not function socially as they had when there was shelter.二、七选五阅读Do you want lots of success in school and in your friendship?

The new program is known as the KNFB Reader app. It can help users listen to the sound of 11 material. Blind people say the KNFB Reader app will make life much 12 . They say it will help with everything 13 reading restaurant menus to studying papers in the classroom. The KNFB Reader makes use of new pattern recognition and image-processing technology, and new hardware for smartphones. People using the app can 14 , or change the position of the camera and read materials out loud. Users say the app has given some people greater 15 . The Reuters news service says these users made the 16 on social media sites such as Twitter. One user, named Gordon Luke, reported that he was able to use the app to read his voting card for the recent referendum in Scotland. Ray Kurzweil told Reuters that the app will be 17 for Android mobile devices in the coming months. He said he may 18 build a version of the app for Google Glass. Google Glass is a small computer screen that can be 19 to eyeglasses. It is able to take photographs, record video and play sound. Ray Kurzweil 20 that ―Google Glass makes sense because you 21 the camera with your head.‖ Mr. Kurzweil started working on what he called ―reading machines‖ in the early 1970s. The idea came after speaking with a blind person who expressed 22 with the lack of technology to assist blind people. 1Mr. Kurzweil‘s first reading machine was the 23 of a washing machine. It cost $50,000. The technology has continued to improve over the past 20 years. The new smartphone app can 24 and take printed material in one language and change it to another language. But it was not available on a mobile device until now. In the past, it cost more than $1,000 to use the software app with a camera and a mobile phone.

But a new study suggests being handsome may not always work in a man‘s favour – at least when it comes to his career.The research claims that attractive men are less likely to be given a job in a competitive workplace because they intimidate bosses.?It‘s not always an advantage to be pretty,‘ says Marko Pitesa, an assistant professor at the University of Maryland. ?It can backfire if you are perceived as a threat.‘Interestingly, in Pitesa‘s study, it was male attractiveness in particular, rather than female beauty, that made the most difference. If the interviewer expected to work with the candidate as part of a team, then he preferred good-looking men.However, if the interviewer saw the candidate as a potential competitor, the interviewer discriminated in favor of unattractive men.In the first experiment, 241 adults were asked to evaluate fictional job candidates based on fake qualifications and experience, in an online setting.2Men evaluated men and women evaluated women. Interviewers were primed to either think of the candidate as a future co-operator or competitor, and they were given a computer-generated headshot that was either attractive or unattractive.A second experiment involved 92 people in a lab. They were asked to evaluate future competitors or partners in a quiz game, based on credentials that included sample quiz answers, and they saw similar headshots.The patterns of discrimination based on perceived self-interest were the same.Another test opened up to include men interviewing women and women interviewing men.There was still a preference to cooperate with the attractive man and compete against the unattractive man.A final experiment used photographs of actual European business school students, vetted for attractiveness, and found the same pattern.The results suggest that interviewers were not blinded by beauty, and instead calculated which candidate would further their own career.?The dominant theoretical perspective in the social sciences for several decades has been that biases and discrimination are caused by irrational prejudice,‘ Pitesa says.?The way we explain it here, pretty men just seem more competent, so it is actually subjectively rational to discriminate for or against them.‘On a deeper level, she adds, the behavior remains irrational, since there‘s no evidence that a real link exists between looks and competence.31.

But road cycling is fast catching up as the preferred way of networking for the modern professional. A growing number of corporate-sponsored charity bike rides and city cycle clubs are providing an ideal opportunity to talk shop with like-minded colleagues andclients(客户) while discussing different bike frames. Many believe cycling is better than golf for building lasting working relationships, or landing a new job, because it is less competitive.―When you play golf with somebody you have to decide if you‘re going to beat them, or let them beat you,‖ says Peter Murray, a former architect. ―If they‘re a client and you don‘t want to beat them you have to sort of cheat in order to lose. That seems to me not a good way of doing things.‖ Group cycling, and especially long-distance riding, is a shared experience, Mr. Murray says. Riders often work together and help each other out, taking turns to be at the front so that the riders in their slipstream can save almost a third of the effort needed to travel at the same speed.3In 2005, Mr. Murray, who is a keen long-distance rider, founded the annual Cycle to Cannes bike ride. This six-day charity event brings together architects who want to cycle 1,500km from London to the MIPIM property fair in southern France each March. It has raised ￡1.5m for a range of charities in Britain and abroad.How someone rides a bike can give you a real insight into what a person is like, says Jean-Jacques Lorraine, a regular participant of Cycle to Cannes. ―There is an easy rhythm about conversations on a bike. I often find I‘m saying things on a bike which I wouldn‘t normally say, and equally I‘ve been confided in when I wasn‘t expecting it. Some riders are very single-minded, others more collaborative; some are tactical, others an open book.‖Many long-distance bike riders say cycling, especially over long distances, simply makes them feel good; it lifts their mood and concentrates things down to the essentials. ―The pattern of fuelling, riding, fuelling, arriving, celebrating, sleeping and fuelling again putsall the focus on riding and the company of your fellow riders,‖ says Simon Mottram, chief executive of Rapha, a premium cycling-clothes brand. The simple repetitiveness eases the stresses and pressures of normal life, he adds.Why do cycle rides lend riders so well to networking and making professional contacts? ―Grabbing a quick lunch or drink after work, while great for different reasons doesn‘t give you long enough to get to know someone,‖ he says. Mr. Murray believes long rides break down conventional hierarchical(等级制度) barriers. ―A younger rider can be cycling along with a chief executive and help them in some way and you get a reversal of the relationship. This changes the relationship when they are off the ride too.‖Perhaps the most compelling reason why cycling is a good way to network is because, for many professionals, it‘s a passion and a way of life they share. ―Getting out on the bike is what we‘re all dreaming of doing while we‘re sitting at our computers,‖ says Mr Mottram.

When she wasn’t in the classroom, she was educating her children or grandchildren: correcting our grammar; starting us on collections of butterflies, flowers or rocks; or inspiring a discussion on her most re cent “Book of the Month Club” topic. Mom made learning fun.It was sad for my three brothers and me to see her ailing in her later years. At eighty-five, she suffered a stroke and she went steadily downhill after that.Two days before she died, my brothers and I met at her nursing home and took her for a short ride in a wheelchair. While we waited for the staff to lift her limp body back into bed, Mom fell asleep. Not wanting to wake her, we moved to the far end of the room and spoke softly.After several minutes our conversation was interrupted by a muffled sound coming from across the room. We stopped talking and looked at Mom. Her eyes were closed, but she was clearly trying to communicate with us. We went to her side.“Whirr,” she said weakly.“Where?” I asked. “Mom, is there something you want?” “Whirr,” she repeated a bit stronger. My brothers and I looked at each other and shook our heads sadly.Mom opened her eyes, sighed, and with all the energy she could muster said, “Not was, say were!”It suddenly occurred to us that Mom was correcting brother Jim’s last sentence. “If it was up to me…”Jim leaned down and kissed her cheek. “Thanks, Mom,” he whispered. We smiled at each other and once again shook our heads…this time in awe of a remarkable teacher.56. When Mom said, “Whirr”, what did she really want to do?A.She wanted to tell her sons her will.B.She wanted to have something to eat before she died.C.She wanted to correct the mistakes Jim made while talking.D.She wanted to teach her sons more because she was dying.57. Which of the following statements is NOT right?A.Mom was a good teacher and never wanted to stop her teaching.B.Mom was always making her teaching fun.C.Mom didn’t forget her teaching until she died.D.Mom was no longer a teacher when she was at home.58. What does the writer think of his mother?A.He loved her but was tired of his mother’s teaching at home.B.His mother should forget her teaching and enjoyed the rest of her life.C.His mother was great because she devoted herself to teaching.D.His mother was an excellent teacher before she was retired.59. Which of the following is the best title of this passage?A. Once a teacher, always…B. Mom’s willC. A teacher’s lifeD. A teacher’s devotionBFrom the outer of New York to the heart of Singapore, nature is everywhere you’re not looking in some of Earth’s most crowded big cities. Outdoor adventure is often just a few stops on the train—or a short drive- away from the annoying crowds. Here are a few favorites to get you going:Mount Hollywood Trail（林间小道，乡间小路）Los AngelesIt’s not a skyscraper or a Ferris wheel, and there’s no expensive restaurant up top. But if you want an absolutely unforgettable, no-admission-charged, 360-degree view of the entire Los Angeles region, it’s yours. All you have to do is walk a little. One of the preferred exercise routes, the Mount Hollywood Trail, is easily accessed from the parking lot of the famous Griffith Observatory; you see what you get at the end of this steep 1.5-mile trail, which winds its way through the Griffith Park wilds up to the mountain’s 1,640-foot peak.Bronx River, New YorkIt may not be on your Top 10 list of things to do when you finally get to the Big Apple, but exploring the almost-secret river that flows through one of New York’s most mysterious boroughs (自治市) is an unforgettable experience. The Bronx River Alliance, a non-profit group that has worked tirelessly to bring the much-abused river back to life , operates cycling and canoeing trips along the river, from the rugged Hunts Point section down near the harbor on up through the borough.Southern Islands, SingaporeBelieve it or not, tightly packed Singapore does have plenty of open space left. There are actual trails right in the middle of everything, if you know where to look. But to really get away from it all, the Southern Islands, a small group of little green dots just off the city state’s southern shoreline, are just the thing.Lee Valley, LondonThis East London river valley changed last summer, when anyone near a television got an eyeful of Olympic Park, built directly in the middle of the valley. Inside the park, beautifully landscaped sections quickly became a favorite relaxation spot for games goers. At present, you’ll find miles of walking paths worth exploring. Start at the Waltham Cross train and follow the signposted walking route southbound, guiding you past important historic industrial areas, through interesting city neighborhoods, past the western side of Olympic Park and on to the Thames.60．If someone wants to enjoy an unforgettable experience for free , he can go to ______.A. Mount Hollywood Trail and Bronx RiverB. Mount Hollywood Trail and Southern IslandsC. Lee Valley and Southern IslandsD. Bronx River and Lee Valley61. The writer of the passage wants to ________.A. inform the readers that nature exists in crowded big citiesB. appeal to more people to outdoor adventureC. recommend several historical spots to readersD. present various approaches to outdoor adventure62. We know from the passage ________.A. it’s difficult to find a proper trail in packed SingaporeB. the Thames is not far away from the East London river valleyC. The Bronx River Alliance has succeeded in running the riverD. you may have trouble reaching the Mount Hollywood Trail。

高三英语高效限时训练
高三英语高效限时训练姓名:___________班级:___________一、阅读理解ABeavers(海狸), like humans, change their surroundings to fit their needs. Known as nature’s engineers, they tear trees down to build homes to live in and dams to raise water levels for protection from enemies. Dams also slow water’s flow while blocking sediment(沉积物)that would otherwise flow downstream. The resulting wetlands often attract wildlife diversity where none had existed. There are challenges, though. Beaver dams sometimes cause flooding, and most people prefer trees alive and upright.Communities face a delicate balancing act, learning to coexist with beavers. Last winter, many people enjoying Winston Path became beaver fans as one furry family transformed Swallow Pond into an oasis for birds, frogs, turtles and deer.Yet such activity caused concern. As beavers worked, they raised water levels about five feet. The increased depth allows beavers to survive underwater if the pond ices over. But county officials were concerned about how higher water would affect the soil bank supporting Winston Path.To find a good balance between protecting the path and the beavers, the county introduced a“ beaver baffle”— a pond leveler.Beavers often rush to fill holes in their dams.Baffles stabilize water levels by creating a hidden exit for high water to escape through the dam, unnoticed by the beavers.People love the beavers but they also love the mature trees. Recently, Catherine Jones,18, organized a tree-caging event — putting wire cloth around large tree trunks to discourage beavers from biting them. It also protects people from injury due to random trees falling.“We cover the trees we don’t want them to eat, while planting periodically oth ers they like,“said Jones.“We need-to learn to give up a little of our wants to share the Earth’s resources.”Swallow Pond’s 2023 project will restore proper water depth and improve wildlife habitat without creating problems for the path. The balancing act continues.；1. What is the first paragraph mainly about?A．Where beavers’ favorite surroundings are.B．What effects beavers have on their habitat.C．Why beavers are called nature’s engineers.D．How beavers help attract wildlife diversity.；2. Why did the beaver family’s activity cause concern?A．Swallow Pond would flood often.B．Sediment would flow downstream.C．The popular path might be damaged.D．Beavers might have to live underwater.；3. What do the underlined words“beaver baffle”refer to in paragraph 4?A．A block to keep beavers away. B．A tool to fix holes in the dams.C．A device to maintain water level. D．A material to protect the soil bank.；4. What is the theme of Swallow Pond’s 2023 project?A．Biological diversity. B．Harmonious coexistence. C．Prevention of natural disasters. D．Preservation of wildlife habitat.BThe safeguarding of intangible cultural heritage is considered an important part of sustainable development. Among the 629 UNESCO-listed traditions are five entries in Estonia, the most recent of which is the building and use of dugout canoes in the Soomaa region.Every year, before spring, Soomaa National Park transforms into an almost drowned world, when water from melting snow in the eastern uplands floods the low-lying forests, wetlands, roads and yards of the residents who still live here. The water level rose so high that villagers could roll a dugout canoe right through their windows and into their living rooms. Everyone has had to learn to adapt to the natural annual phenomenon.Building a dugout canoe requires a good trunk of an aspen, which grows throughout the forests of Estonia. Once cut down, the trees are peeled and shaped like a cigar using an axe. From here, the inside of the boat is carved out to give it shape. Builders cut the frame down to a few centimetres in thickness. A long log fire is then built alongside the canoe, which is filled with several bucketfuls of water and left to warm up. Once the water has evaporated, sticks are squeezed into the frame lengthways to open it up. Aspen is a soft wood and a trunk half a metre across can be expanded into a metre-wide boat. The boat is then left to cool in the shade and is traditionally finished the following spring, once the wood has fully dried, when it’s given its final design and covered with tar.Aivar Ruukel, one of only five Estonians who still preserve the skill, chooses to build them as a way to connect with the history, As a young man, Ruukel attended workshops led by two master boat builders, both in their 70s at the tim e. He hopes that by the time he’s 70 there will be more young people doing the same. Enthusiasts hope that its joining the heritage list will safeguard the ancient practice and attract the next generation of boatmasters to keep the tradition alive.；5. Why do villagers have to preserve dugout canoes?A．To survive floods. B．To go canoeing in the park.C．To learn about a natural phenomenon. D．To apply for intangible cultural heritage.；6. What’s the right order of building a dugout canoe?① The boat is left in the shade to dry.② The inside of the boat is carved out to give it shape.③ Builders warm up the canoe and open the frame up.④ The boat is given the design and covered with the tar.⑤ Builders remove the barks and make the trees into cigar shapes.A．⑤③②④①B．②⑤④①③C．⑤②③①④D．②③⑤④①；7. Which statement will Ruukel probably agree with?A．Young people shall become boatmasters.B．The practice will die out in the next generation.C．More people are needed to pass on the tradition.D．One cannot master the skill without learning history.；8. What is the best title for the text?A．Dugout canoes come to life B．Boat building industry in Estonia C．Cultural heritage protection in Estonia D．Dugout canoes in Estonia boat to future二、七选五阅读Maybe you are an average student. You probably think you will never be a top student. This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here’s how:Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First set your time for eating, sleeping, dressing, etc. 9 Don’t forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you realize what is happening to your time.10 Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject.Make good use of your time in class. 11 Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.Study regularly. When you get home from school, go over your notes, and review the important points that your teacher has mentioned in class. If you know what your teacher is going to discuss the next day, read that material. 12 If you do these things regularly, the material will become more meaningful, and you’ll remember it longer.Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. 13 A．Behave yourself at home.B．Find a good place to study.C．This will help you understand the next class.D．Then decide a good, regular time for studying.E．Make full use of class time to ask your teacher questions.F．Take advantage of class time to listen to everything the teacher says.G．The world won’t end if you don’t pass a test, so don’t be over worried.三、完形填空Every week, Andy goes for a walk and about two miles away, his friend Gabe does the same thing at the same time.

But some are moving into their own places as social norms (规范) develop.When Alan, a civil servant willing to challenge and reform this conventional stereotype (陈规), decided to move out of his family home in Singapore, it still took the 27-year-old a month to talk about the topic with his parents. He feared they wouldn’t understand. After all, Alan’s home was a pleasant place. The family’s three-bedroom condominium (公寓) wasn’t far from the city-state’s central business district. There was homemade dinner on the table each night, and his laundry was always donefor him. “There wasn’t a push factor, just pull factors,” he says. “I’d lived with my parents my whole life, so I just wanted to experience what it’s like being by myself, you know?”In the West, leaving home is just another milestone in adulthood. Yet in most Asian societies, things are different. Culturally, moving out is sometimes considered as showing disrespect to your parents, which makes it even challenging and praiseworthy. In Singapore, living at home until marriage is a common practice; an estimated 97% of unmarried individuals lived with their parents in 2013.While the trend is in part driven by deep-rooted ideas of filial piety (孝道), it’s also linked to government policies on accommodation for young people. Most Singaporeans live in public housing units, apartments funded by the state that are known as HDBs. About 90% of those who live in HDBs own their home.Those who can’t buy HDBs can rent via the private property market — but costs are much higher. “These cost restrictions,” says Dr Chua, a professor of sociology, “effectively keep most young, unmarried people living at home with their parents.”Yet Alan, who now rents a flat in Hougang with two friends from junior college, is among the courageous young pioneers resisting the long-time cultural norm. These commendable young people are deciding that the price of the freedom to organize their own life is worth it and stepping out of their home.；4. What can we know from the second and third paragraphs?A．The East and the West are very different in most aspects.B．Alan decided to live separately mainly due to some objective reasons.C．The majority of single young people followed social customs in living in 2013. D．In the East, it is culturally acceptable for the young to live separately from the elderly.；5. What mainly causes most single young people to live with their parents in Singapore?A．Their parents’ expectations.B．Their personal wish.C．The home environment. D．The traditional culture and housing prices.；6. What is the author’s attitude towards the young Singaporeans like Alan moving out? A．Confused. B．Positive. C．Indifferent. D．Doubtful.；7. What is the best title for the text?A．Young Singaporeans’ Relationship with Their ParentsB．Young Singaporeans Fighting Against Old Social CustomsC．Young Singaporeans Striking Out Their Way to IndependenceD．Young Singaporeans’ New Way to Solve High Housing PricesCEradajere Oleita thinks she may have a partial solution for two of our country’s continuous problems: garbage and poverty. It’s called the Chip Bag Project. The 26-year-old student and environmentalist from Detroit is asking a favor of local snacklovers: Rather than throw your empty chip bags into the trash, donate them so she can turn them into sleeping bags for the homeless.Chip eaters drop off their empty bags from Doritos, Lay’s, and other favorites at two locations in Detroit: a print shop and a clothing store, wher e Oleita and her volunteer helpers collect them. After they clean the chip bags in soapy hot water, they cut them open, lay them flat, and iron them together. They use materials from old coats to line the insides. It takes about four hours to make a sleepi ng bag, and each takes around 150 to 300 chip bags, depending on whether they’re single-serve or family size. The result is a sleeping bag that is “not allowed water to enter, not heavy, and not difficult to carry around,” Oleita said. Since its start in 2020, the Chip Bag Project has collected more than 800, 000 chip bags and created 110 sleeping bags since last December.Sure, it would be simpler to raise the money to buy new sleeping bags. But that’s only half the goal for Oleita — whose family moved to the United States from Nigeria a decade ago with the hope of achieving a better life－and her fellow volunteers. “We are devoted to making an impact not only socially, but environmentally,” she says.And, of course, there’s the symbolism of saving bags that would otherwise land in the trash and using them to help the homeless. It’s a powerful reminder that environmental injustice and poverty often go hand in hand. As Oleita stated, “I think it’s time to show connections between all of these issues.”8. What’s the aim of the Chip Bag Project?A．To draw the snack lover’s attention to the homeless.B．To change the chip bags into sleeping bags for the homeless.C．To recycle the garbage to remove the poverty for the country.D．To help solve the environmental pollution caused by chip bags.9. What can we learn from Para. 2?A．Chip eaters can place the empty bags wherever they want.B．Eradajere Oleita collects the empty chip bags independently.C．The sleeping bags are tough but not easy to carry around.D．The procedure of making a sleeping bag needs masses of chip bags.10. What does the words mean by Oleita in Para. 3?A．The environmental issues should be stressed.B．Poverty should be lifted out of the homeless.C．The Chip Bag Project will impact the society and environment.D．The Chip Bag Project will be devoted to achieving a better life.11. What can be inferred from the text?A．Chip bags are always used to help the homeless.B．Chip bags are only useful in addressing the environmental problems.C．The issues of environment and poverty will be stressed in the future. D．Environmental injustice and poverty are disconnected with each other.二、七选五阅读It is very important to keep fit and stay healthy. A lot of people fail to believethe good that daily exercise does to health and only begin to do so when they suffer from health problems. 12Regular(经常的)exercise helps you keep in good shape. Maybe, you are one ofthe many overweight people struggling with problems of body shape, yet you do not want to do anything about that.
