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.

Where is this text most likely from?A.A diary. B.A guidebook.C.A news report. D.A story book.(二)During the COP27 climate conference (会议) in Sharm el-Sheikh, Egypt, an important deal on “loss and damage” was reached. This was a big step forward because at COP26 conference in Glasgow, Scotland, there were no talks on loss and damage at all. The plan is that richer countries will pay money into a special fund that will be used to help poor countries.Loss and damage means the damaging impact of climate change on developing countries. For nearly 30 years, poorer countries have been asking richer countries formoney to help to protect communities from the effects of climate change. Richer countries have produced the most greenhouse gases, but poorer countries are often the worst affected by extreme weather conditions because they are less well equipped to face extreme climate events.Brazil’s newly elected President Luiz Inacio Lula da Silva made a speech about preserving the largest rainforest on Earth, the Amazon. During the last 50 years, more than 17% of the Amazon rainforest has been destroyed to make way for farms and towns. However, in his speech, Lula promised that there would be zero deforestation (伐树) in the Amazon by 2030. The conference didn’t just focus on world leaders. It brought together more than 45,000 people to discuss how climate change is affecting their lives. Climate refugees (难民) also had their voices heard. Tshilombo from the Kakuma refugee camp in Kenya said, “Refugees don’t only flee becaus e of war or conflict. It’s also about drought, the effects of climate change.”Some countries weren’t happy with the overall outcome of COP27 because decisions weren’t made on cutting the use of fossil fuels, such as coal, gas and oil, etc. The UK Governme nt’s Alok Sharma said, “I’m incredibly disappointed.”However, this deal was a great achievement for developing countries. Sherry Rehman, the climate minister for Pakistan, said, “I am confident we have tuned a comer in how we work together to achieve clim ate goals.”;4. What is a successful outcome of the COP27 climate conference?A.The deal on loss and damage.B.The deal on using fossil fuels.C.The deal on rainforest preservation.D.The deal on helping climate refugees.;5. What has made it difficult for developing countries to fight against climate change? A.More greenhouse gases.B.Massive deforestation.C.Shortage of money and supplies.D.Terrible weather conditions.;6. What can we infer from Paragraph 3?A.Climate change is influencing people’s live s.B.17% of the Amazon rainforest was destroyed.C.Many factors lead to the appearance of refugees.D.There will be less deforestation in the Amazon by 2030.;7. What would Sherry Rehman probably agree with?A.Never put off till tomorrow.B.Many hands make light work.C.Knowledge starts with practice.D.No way is impossible to courage.(三)What are you doing this weekend? Perhaps you're spending time with family, hanging out with friends, or maybe you're going to play a sport. All around the world, people chill out at the end of the working week and take part in leisure activities. In many countries, the weekend consists of Saturday and Sunday, while in others Friday and Saturday are the days of rest. In Afghanistan, Thursday and Friday form the weekend, while in one country, Brunei, Friday and Sunday are the days off.Have you ever stopped to wonder, though, exactly where it originated? And how is the concept going to change? The modern weekend took shape during the Industrial Revolution. In the early 19 century, in areas such as the north of England, people began to leave the countryside to work in towns and cities. There, new factories were springing up. Their working lives were once ruled by nature, with the amount of work depending on the changing seasons. Now, their employers demanded a different rhythm-a six-day week of up to 12 hours a day, followed by one day of rest.Campaigns for workers' rights appeared. By the end of the century they had managed to reduce the working week to five and a half days. This meant that working people could take an interest in hobbies such as photography, which was very new at the time. In the US in the 1920s, the industrialist Henry Ford helped to create the weekend. He gave all his workers Saturday and Sunday off work. His factories manufactured cars, and he wanted to allow his employees time to purchase and enjoy the cars they were producing.These days, in many countries, working a 40-hour week is normal. Many people have a nine-to-five job, but even that is rapidly changing. Technology enables more people to work from home and plan their own use of time. This means that an official period away from work is becoming less important. Perhaps in the future we will work fewer hours altogether. If we become more productive, we should be able to afford the same lifestyle by working fewer hours. It has been estimated, for example, that a worker in the US can achieve a 1950s standard of living by working just 1l hours a week. Some people have recommended a 21-hour working week to help with unemployment, climate change and inequality. However, a change like that may mean more leisure time but it will probably limit people's ability to earn money to enjoy it.8. What does the underlined word “originated” in the second paragraph me an? A.Relaxed. B.Started. C.Appeared suddenly. D.Stopped. 9. What happened as a result of campaigns on behalf of workers?A.People became more inventive.B.People worked fewer hours per day.C.People worked fewer hours overall.D.People found employment in leisure industries.10. The writer says an American businessman gave his workers time off so that A.he could produce more cars.B.they could spend money on cars.C.he didn’t have to pay them to drive.D.they would enjoy working with him.11. Why does the writer suggest the weekend may be less important now? A.Because we start work later than we used toB.Because nobody works over 40 hours a week.C.Because technology empowers individuals to arrange their own time. D.Because people are out control of their working week.二、七选五阅读Mondays are kind of annoying. 12 A recent survey says that most people get the pre-work “Sunday blues”. Starting your Monday feeling sad, anxious and unorganized is hardly the way to kick off a healthy week.The solution? Set aside a little time on Sunday to purposefully prepare yourself for the five days ahead, suggests women’s health expert Marsha Hudnall. 13Do some meal preparations.Figuring out what to have for dinner on weeknights can be surprisingly stressf ul. Stretching out a menu plan on Sunday and swinging by the grocery store for ingredients will help you eat well. Go a step further by chopping and cooking vegetables and a protein (like a roast chicken or scrambled eggs). 14 Or finally attempt a di fferent diet you’ve been meaning to try. For easy dinner planning, just order, and you’ll have a week’s worth of raw materials for delicious and healthy meals.Start a Sunday stress-relief habit.“To be healthy, we have to take care of body and mind,” says Hudnall. Stress has a major impact on health and our ability to concentrate. 15 Four ideas to try: a guided meditation with the help of an app; forest bathing-a practice known as shinrin-yoku in Japan, which basically means taking a long walk or hik e in a wooded area; gentle exercise like yoga; or time cuddling and playing with your pet.16Why not prepare your favorite clothes for Monday? Studies show that what you wear can have a significant effect on your mood. So make Monday the day you wear your favorite clothes or show the latest addition to your wardrobe (衣橱). It’s also a good idea to get some nice coffee or music ready, which will give you something to look forward to on your Monday commute.A.Give yourself something to look forward on Monday.B.Even Sunday afternoons turn sour as we think of the workweek ahead.C.Then all you have to do is heat and plate when you come home from work. D.Therefore, starting a Sunday stress-relieving habit can begin a week feeling strong and focused.E.Try creating a relaxing and winding down Sunday night so that you can recharge and get ready for Monday.F.Taking on just a few of these simple tips every Sunday will help you launch a productive, less stressful week.G.Wailing until the last moment to do weekend chores like paying bills or doing laundry can leave you anxious and stressed on Sunday.三、完型填空The stage lights dimmed (变昏暗), and I took a quick look from behind the heavy black curtains into the audience.

高三语文限时训练(含参考答案)

高三语文限时训练一、阅读下面的文字,完成1~3题。

(9分)有着5000多年历史的中国传统艺术是一条璀璨星河,它的精神和血脉对世界文化艺术的发展起到了极其重要的涵养作用,对世界众多艺术家产生过直接或间接的影响。

尤其是当西方传统写实绘画的发展处于困境之时,中国传统艺术更是以其独具特色的艺术魅力和表现形式启迪了一大批现代艺术家,他们从中汲取营养,摸索前行,在很多西方艺术史论家眼里,中国传统艺术是世界艺术的高峰。

中国传统艺术对西方的影响可以追溯到14世纪的欧洲,当时中国的瓷器、丝绸和国画等商品一直流行于欧洲的上层社会中。

在法国,中国的龙凤图案常被运用于各类织物中。

在15世纪的意大利和法国瓷器制作中,盛行模仿中国青花瓷器造型。

18世纪法国“罗可可”绘画大师让·安东尼·华托青年时期曾研究中国的《百戏图》,他的作品《发舟西苔岛》具有明显的中国意味和东方艺术特色。

著名的评论家雷文曾说:“凡于中国宋代之风景画研究有素者,一见华托此作,必讶其风景之相似,其画中远山犹保持作者之生命。

青峰缥缈,用单色作烟云。

华托所惯为者,亦中国山水画最显著之特色也。

”日本学者小林太市郎认为应该将17~18世纪流行于欧洲的“罗可可”艺术称为“中国—法国式”。

世纪新古典主义大师安格尔则因为具有浓郁东方意味的艺术语言,被当时的人们称为“误生在19世纪雅典废墟上的中国画家”。

19世纪中叶,摄影术的发明,对西方传统写实绘画带来了巨大的冲击,西方绘画艺术的发展陷入了困境,艺术家开始寻求新的出路。

此时,博大精深的中国传统艺术思想和独具特色的艺术表现形式,给了西方艺术家以启迪,使得西方艺术在现代主义道路上继续前行。

一些杰出的画家诸如梵·高、高更、毕加索、马蒂斯、克里姆特、大卫·霍克尼等,分别从不同的方面和角度吸取中国艺术的养分,探索出全新的艺术风格,创作出一大批具有划时代意义的艺术杰作,对世界艺术史的发展产生了深远的影响。

材料一:中国人说中国话,用汉语写作,可是我们了解自己的语言吗如果不了解,如果我们超越汉语的表达界限说话,会出现怎样的情形呢长期以来,我们总是一厢情愿地设想,西方语言固有的成分,汉语中也一定或明或暗地隐藏着,最害怕被西方人说汉语是一种蒙昧的语言。

冯友兰先生的意见,就代表了这样的立场,他说中国哲学与西方哲学是古今之争。

换句话说,中国哲学之所以“落后于”时代,是因为汉语“落后”;但是,按照这样的逻辑推论,汉语永远不得不落后,除非汉语成为拼音文字。

与其说汉语与拼音文字之间,中国哲学与西方哲学之间,是人类古代语言与现代语言或原始思维与现代思维之争,不如说它们之间仅仅是一种空间上的并列关系,彼此相互外在,互不附属,一点儿也不像。

所谓“先进”与“落后”的断语之所以不中用,是因为这个标准来自西方。

举个例子来说,按照西方语言和语法标准分析汉语,往往就要说外行话,因为这个分析的工具不中用。

“中国言语的构造上主语(subject) 与谓语(predicate) 的分别极不分明,换言之,即可以说好像就没有这个分别。

这是中国言语构造上的最特别处,而其影响则甚大”(张东荪)。

既然汉语几乎就没有主语与谓语的分别,那么当我们硬说有这个分别时,就好像“使中国文法亦穿了一套西服”(张东荪)。

有怎样的害处呢蒙蔽了汉语的特性或者说“面貌”,就像即便穿着笔挺的西装,相貌却还是中国的,无法蒙人。

张东荪先生援引了高本汉所分析的例句:Albert's mother gives him cakes.这个英文句子中哪个词是主语,几乎一望便知,拉丁文和希腊文中的句子,也是如此。

当高本汉认为西方语言是一种进化了的语言时,张东荪却一针见血地指出:“中国言语与外国言语是构造上的不同,无所谓进化与不进化。

The gardens themselves boast thousands of species of plants. This is a lovely place to relax and explore the beautiful surroundings.Parc des Buttes-Chaumont: over 24 hectaresIf you want to get off the tourist trail and hang out with true Parisians, this park is the perfect spot for a relaxing picnic or a leisurely wander. It is in the 19th district and is one of the largest parks in Paris. Cross its lake on the suspension bridge, or admire the waterfalls and attractive temples.Jardin du Luxembourg: over 25 hectaresThese beautiful gardens were first laid out in 1612 as the gardens of the Luxembourg Palace. They include a geometric forest, French and English style gardens, as well as a large pond. There is so much to see and do with activities especially for children, such as slides, rides and puppet shows, as well as leisure and sporting activities for adults. The gardens are home to more than one hundred sculptures.Le Parc de la Villette: 55 hectaresThis urban cultural park is so much more than just a park as it is home to numerous music venues, exhibition spaces and cafes. It is also home to no less than 12 gardens, which all follow different themes. The Passenger Gardens, for example, which are built on what was once the sheep market, support a variety of ecosystems, demonstrating the importance of biodiversity.1. Which green space probably suits students who are interested in botany?A.Jardin des Plantes. B.Parc des Buttes-Chaumont.C.Jardin du Luxembourg. D.Le Parc de la Villette.2. Which is special about Jardin du Luxembourg?A.They used to be royal gardens. B.They are Parisian favourite gardens. C.They feature American style gardens. D.They house a variely of African animals.3. What can visitors do in Le Parc de la Villette?A.Visiting museums. B.Attending concerts.C.Admiring waterfalls. D.Watching puppet shows.BA team of researchers at ETH Zurich has the perfect long-lasting solution to our fog problem. 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? If you want to learn how to balance your friendship and study, read on.• Talk about your goals for school.Share what academic success looks like for both of you. 12 Before the semester starts, sit down and discuss what you’d both like to achieve.• Share tips and tricks with each other.Exchange study techniques to learn how to be more successful.

But it’s not clear that these benefits come specifically from vitamin C.The Age-Related Eye Disease Study found that a daily supplement containing 500 mg of vitamin C can help slow the progress of macular degeneration, an age-related eye disease that causes vision loss. But we don’t know what benefits, if any, are provided by vitamin C in particular.Many people take vitamin C supplements in unnecessarily high doses to prevent or treat various conditions for which its effectiveness is unproved. The vitamin C supplements have variously been said for staving off sunburn and improving the appearance of wrinkles. None of these benefits have been confirmed in scientific studies.Perhaps the best-known and most widely promoted use of high-dose(高剂量)vitamin C is to prevent or treat the common cold. Most of the evidence shows that high-dose vitamin C will, at most, shorten a cold by one day. In ordinary circumstances, vitamin C has no preventive value, although a few studies have reported a 50% reduced risk of developing colds among people taking vitamin C in extreme circumstances-for example, skiers, marathon runners, and soldiers working in extreme conditions.The recommended vitamin C dosage per day for healthy women is 75 mg per day. For adults, the highest safe daily intake is likely to be 2, 000 mg per day. Vitamin C is water-soluble, so any amount more than you need will not be stored in the body. It’s safe in almost any amount from foods, and supplements in recommended amounts are also regarded as safe for most people. In some people, high doses-more than, say, 2, 000 or 3, 000 mg per day-can cause a variety of symptoms. People with kidney conditions should take no more than 1, 000 mg a day.;4. What can we learn about vitamin C in the first paragraph?A.It can be of better effect in higher doses.B.It can be a cure for age-related eye disease.C.It can help slow the progress of some illness.D.It can reduce the risks of the mouth cancer.;5. What function does vitamin C have intreating the common cold?A.It can help people save plenty of money.B.It can stop soldiers from catching a cold.C.It may reduce a cold by one day at most.D.It may prevent the common cold efficiently.;6. How much Vitamin C are healthy women advised to take per day?A.75 mg.B.500 mg.C.2, 000 mg.D.3, 000mg.;7. Where is this text probably taken from?A.An exam paper.B.A travel journal.C.An art guidebook.D.A science magazine.CThis year will have been the warmest in the UK, the Met Office has said. Although for many people the record from the year that attracted the most attention was that the summer heatwave reached 40. 3℃, the organization said that more significant was a figure 30 degrees lower-the average temperature over the course of the year.Although the exact temperature will need to be confirmed in the new year, the Met Office predicted that 2022 is going to exceed (超过)the previous record for the warmest annual average, which was 9. 88C in 2014. Apart from this month, every other month in the UK in 2022 was warmer than average. New Ye ar’s Day 2022 was the warmest on record, exceeding 16℃ in North Wales. Dr. Mark McCarthy, head of the National Climate Information Centre, said: “While many people will remember the summer’s extreme heat, what hurts people most, especially the elderly, this year is the relatively consistent heat through the year. ” Although this summer was the fourth warmest on record, it was the first in which the temperature exceeded 40℃.McCarthy said that we can expect to see increasingly warmer summers as a consequenc e of climate change. “The warm year is in line with the impacts we expect as a result of human-related climate change, ”he said. “Although it doesn’t mean every year will be the warmest on record, climate change continues to increase the chances of increas ingly warm years over the coming decades. ”Rebecca Newsom, head of politics at Greenpeace UK, said: “These aren’t the kind of records you want to be breaking. Record-breaking investment in the renewable technologies will get us out of this mess.At present though, Britain is ready for rain, with forecasters warning of difficult driving conditions caused by wet weather over the next few days. Although temperatures will stay mild for much of the UK, the Met Office warned that the rainfall will hit England and Wales this Saturday and Sunday.;8.

I have, however, struggled to think of an answer. Yes, we do have our own national dishes. 12Fish and chips, as you could guess, is made up of battered fish and chips. It is often accompanied by mushy peas (豌豆糊), which consists of peas mashed up to form a thick paste. The majority of British people really do love this dish but it is not something that we would eat, say, on a weekly basis. 13 British people associate this dish with the seaside and it’s something that will usually be eaten on a day trip there.14 This is made up of roast meat, usually chicken or beef, accompanied by roast vegetables and a meat sauce. It is usually eaten on a Sunday, perhaps for a special family dinner.Although we do have our traditional dishes, we do not eat these on a daily basis. On a daily basis many British people will eat rice or pasta dished. 15 You can see this by looking at the range of international foods in the supermarket or at the va riety of different restaurants you can find on our high streets.16 However, perhaps unlike other countries, we tend to prefer to cook recipes influenced by other cuisine.A.We eat them as the seasons change.B.But how much do we actually eat them?C.In conclusion, we do have our national dishes.D.Another favourite British dish is the roast dinner.E.Our diet has been greatly influenced by other countries.F.It’s also not usually something that you would cook at home.G.You’ll be served a traditional dish if you get invited for dinner at a British family’s home.三、完形填空The public library is one of the greatest inventions humankind has ever imagined and actually made happen. Libraries are a (an) 17 , quiet place where all people can hang out and read, without having to 18 anyone anything. Apart from being a place that is full of 19 to borrow, libraries are something that offers 20 and warmth. A post on Twitter celebrating the wonderfulness of libraries 21 this point perfectly.“Today a woman with developmental disabilities came into the library, and she was 22 ,” wrote a Twitter user. “She didn’t 23 her address, but her phone number was in her pocket on a piece of paper with Elmo on it. She kept saying, ‘The library is a safe place.’We called and her guardians (监护人) came right over. It seemed that they were not worried at all. Apparently this happens pretty 24 . They even stayed long enough for her to 25 some new books and Sesame Street DVDs. The library is a safe place indeed.”The post 26 others to share their own stories of libraries being safe places for them, and it’s enough to 27 even the hardest of hearts. For people who grew up in dysfunctional (功能失调的) homes, the library can be a safe heaven of calm and kindness. For people lacking financial means, the library is a space that provides free education and free entertainment, as well as a free indoor place to go. This is the reason why 28 people grouped to libraries when they have nowhere else on earth---the only place that doesn’t 29 money. We cannot understate Literal lifesavers. Libraries also fill up a lot of gaps in other social 30 and help people find their way to information about other opportunities. They open the doors to so many 31 .17.

At first people knew this club. As a result, we had only 15 members. And I 33 (laugh) at for being crazy. However, I didn’t lose heart and I insisted.

2023届高三英语晚自习限时训练

2023届高三英语晚自习限时训练【3月30日晚,限时:不超过65-70分钟】一、阅读理解(一)Located in the tropical forests in Xishuangbanna, southwest China’s Yunnan province, the Asian Elephant Breeding and Rescue Center (AEBRC) is dedicated to giving careful and effective protection to wild elephants.Though the jungles provide rich sources of food and water for the elephants, they can also pose a threat to them if they become ill or injured, making it difficult for them to survive in the wild.In August 2015, a baby elephant that was less than one month old was abandoned by her herd at the d oorway of a farmer’s house in Simiao, Pu’er city. Vets from the AEBRC came and took the animal to their center for treatment. She was found to have intra-abdominal infections and heart failure. She was also at risk of blood poisoning.The baby elephant finally recovered after proper treatment by the keepers at the center. However, without the presence of her mother, she became malnourished (营养不良) due to a lack of breast milk. At that time, she weighed only 76 kilograms, much smaller than an average newborn elephant. The vets decided to feed her goat milk, and as she was born in the Chinese Year of the Goat, the elephant was named Yang Niu (“Yang” is Chinese for goat, and Niu means girl). The elephant is now about 6 years old, 1.8 meters tall and weighs 1.3 tonnes.Currently, there are 11 rescued Asian elephants living at the center and being cared for by 27 keepers, who spend more than 10 hours with them each day. Thanks to these efforts, the population of Asian wild elephants in the province has reached 300 from 150 over the past 30 years.The local government has designated (指派) a place as a source of food for the elephants so that they do less damage to villagers’ crops while looking for food. They’ve also monitored the elephants using technologies such as drones to keep track of their activities and prevent encounters between villagers and the elephants. The local government has also purchased commercial insurance for residents to compensate them if the elephants attack them.;1. What can be a threat to elephants’ survival according to the text?A.Lack of food sources. B.Illegal hunting.C.Physical problems. D.Destruction of forests.;2. What does the example of a baby elephant stress?A.The recovery of Yang Niu.B.The efforts made by keepers.C.The risks facing baby elephants.D.The importance of mother elephants.;3. What does the author mainly talk about in Paragraph 5?A.The number of elephants endangered.B.The urgency of rescuing wild elephants.C.A steady growth of elephant population.D.A rising trend of animal overprotection.;4. Why has the government designated a place for elephants?A.To keep track of their activities.B.To prevent them from damaging crops.C.To save them the trouble of looking for food.D.To ensure the growth of the elephant population.(二)No one can resist the temptation (诱惑) of snacks. But at the same time, you may be underestimating how many calories a snack contains. What would happen if you had a bag of crisps (炸薯片) a day? Eating an extra packet of crisps a day could lead to a weight gain of 6. 35 kg after a year, The Times reported.People underestimate the number of calories in their snacks, with experts warning that eating a bag of crisps every day could lead to a stone of weight gain in a year. A survey of around 2 ,000 adults found that about three quarters underestimated the impact of what a small reduction could have. One in ten believed that cutting 200 calories a day would not affect weight. At the same time, many people didn’t seem to know exactly how many calories were in their snacks. When it came to snacks, people struggled, with 95 percent guessing that half a sharing bag of tortilla chips had 214 calories on average, almost half the true figure of 447.Can’t we resist buying snacks? The food environment is to blame. Even though we all know snacking is bad for our health, we can’t help but fill our shopping carts with snacks.Don’t always blame yourself for poor self- control, and supermarket shelves also have to carry this “pot” half.Hugo Harper, head of Nesta’s health team, said the pressure to resist high-calorie snacks should not be put on consumers and that our food environment needed. to be changed, He said,“Our environment has a real impact on what we eat, from advertisements and supermarket promotions to what ‘s available in our local corner shops.Hugo added,“If we had fewer cues to snacks, or were pushed to buy fewer high calorie snacks, we should be able to see real change.”New rules coming into force next month will restrict promotions on foods high in fat, sugar and salt in big shops.;5. What does the author intend to do in paragraph 1?A.List some reasons. B.Introduce the topic.C.Put up an argument. D.Raise a question.;6. What can we know from the survey?A.One in ten people cut 200 calories a day.B.Many people knew how many snacks they ate.C.No one knew the calories the snacks contained.D.Most people lacked the awareness of snacks’ impact.;7. What may cause people to buy more snacks according to the text?A.The food environment. B.Living conditions. C.Consumption ability. D.Supermarket management.;8. Which of the following may be the best title for the text?A.A packet of crisps contains many caloriesB.People can resist the temptation of snacksC.The harm of snacks is beyond your imaginationD.2,000 adults got involved in a consumption survey二、七选五阅读Have you had a talk with someone, and think you are paying attention to him or her, only to realize shortly afterwards that you can’t remember what he said? Oh, perhaps you fail to focus while he is speaking and miss the message that he is trying to deliver. 9 : TVs, radios, traffic noises, telephones, laptops and so on which can make it difficult to listen with our full attention.But how can we listen more effectively? 10 . Professor Jon Kabat-Zinn said, “It’s time for mindful listening to come in. Mindfulness means paying attention in a particular way, with a purpose, at the present moment and non-judgmentally.”11 ? Jon Kabat-Zinn describes three key elements of mindful listening that we can use to improve our listening skills.First of all, be present. When we listen mindfully, our focus should be on the person we are listening to without distractions. 12 . By doing so, we can understand a situation from someone else’s point of view. After all, we often see the world through our own experiences. Finally, listen to our own cues. Our cues are the thoughts, feelings and physical reactions that we have when we feel anxious or angry, and they can hold back ideas and perspe ctives that we’re uncomfortable with. Mindful listening can help us to be more aware of our cues. 13 .In conclusion, the rule is straightforward: simply “Listen”! Listen carefully and attentively. Pay full attention to the other person, and don’t l et other thoughts, like what we are going to say next, distract us.A.Then think in others’ shoesB.Researchers seem to have got itC.How can we deal with mindful listeningD.Modem life is actually full of distractionsE.But how can we apply mindful listening to our lifeF.Next, reflect on the experience you’ve gone throughG.Besides, it allows us to choose not to let them ruin communication三、语法填空阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

D.In a English TV channel.BHurricane Fiona, killing 16 people and bringing the power system to a 3-day stop, struck Puerto Rico, an island country located between Caribbean Sea and the North Atlantic Ocean, on September 18, almost five years after Hurricane Maria hit the island, showing that, as researchers have long warned, storms are now more frequent and cause more damage due to climate change.Back in 2017, Hurricane Maria killed thousands of people and left millions without power for a week. A study in 2019 found that the possibility of terrible events like Hurricane Maria hitting Puerto Rico is now almost five times higher due to climate change.The storms were similar in many ways but had their own features. Maria was a Category (类别) 4 hurricane whose speed was up to 155 mph, while Fiona, a Category 1 storm when it landed Puerto Rico, was gentler, with winds of up to 85 mph, which later increased to 115 mph as the storm progressed through the island.And yet, the heavy rain caused by Fiona brought Puerto Rico to its knees. According to the data by the National Oceanic and Atmospheric Administration, the slow moving storms brought 15.80 inches of rain over a 5-day period, slightly more than Maria at 14.72 inchesThis confirms another long-held thought that, with climate change, horrible storms will not only become more common but also wetter.That’s because the increase in temperatures is leading to more loss of water from the sea and warmer air can hold more water vapor (水蒸气). The average temperature all over the world has already increased by nearly 1.2℃ due to climate change and for each 1℃ of warming, the air’s ability to hold water is thought to increase by about 7%. The latest research suggests that the increase may be three times higher, at 21%.;4. What was a direct cause of more storms in Puerto RicoA.Loss of forests. B.Puerto Rico’s location.C.Human activity. D.Climate change.;5. Compared with Maria, what’s the feature of Fiona progressing through Puerto RicoA.It brought less rain. B.It moved a bit slower.C.It caused a longer power cut. D.It brought more deaths.;6. What do the figures in the last paragraph showA.Rainfall increases with temperature rising.B.Puerto Rico is a place raining all the time.C.Storms are common in Puerto Rico.D.Slower storms cause more damage.;7. What’s the best title for the textA.Puerto Rico: Survival of PeopleB.Puerto Rico: Frequent FloodsC.Climate Change: Wetter Puerto RicoD.Climate Change: Disasters on Their Way to Puerto RicoCSheneman, a 33-year-old artist, was first diagnosed with diabetes(糖尿病) around five years ago, and she says it was a wake-up call. Since then, health has become a huge part of her life.What she realized while battling this condition, though, is that a lot of people weren’t aware of what she went through on a daily basis. “Which is crazy to think about because there are so many diabetics out there,” she said. So, Sheneman came up with an art project that would offer a deep understanding of what diabetics go through.On April 1, she started her journey, a 470-mile walk, from her college town of Cincinnati, Ohio, and her plan is to make it to her hometown of Memphis, Tennessee, by the end of the month.Throughout this journey, people will be able to watch her glucose(葡萄糖) levels through an app that’s connected to her glucose monitor, the Dexcom G6. The monitor provides real-time alerts when her glucose levels vary too high or low.This journey is more than just showing people how physically difficult this walk is. “I want them to understand what it looks like to be diabetic and constantly checking and making sure that you’re eating the right things,” she said, adding that “just something as simple as stress can raise your blood sugar.”Sheneman was told by health professionals to do something simple, like walking every day. However, Sheneman, who grew up backpacking, wanted to test the limits of what was possible. “I think it’s important to understand that being a diabetic is not necessarily limiting you,” she said. “There’s just the most difficult part that you have to get over.”8. Why did Sheneman start the art projectA.To raise people’s awareness of diabetes. B.To raise money for all the diabetics.C.To advertise for her hometown. D.To get sympathy for herself.9. What should Sheneman pay special attention to during the journey A.The reactions and concerns of others. B.The app connected to the Dexcom G6.C.The variation of her glucose levels. D.The physical difficulty the walk causes.10. Which of the following best describes the life of a diabetic like ShenemanA.Colorful. B.Cautious.C.Artistic. D.Adventurous.11. What message does Sheneman seem to convey in the last paragraph A.Sport helps gain confidence in fighting diseases.B.We don’t have to follow the doctor’s advice.C.Nothing can stop one achieving their goals.D.Our path in life will not always be smooth.二、七选五阅读We know that choosing a college major can be very tough. But have no fear! Your choice of major will not lock you into a specific career for the rest of your life. Here’s what you need to know about college majors before you choose.What is a major12 Beyond general college requirements, you’ll also take a group of courses in a subject of your choosing such as Chemistry, Literature, or Political Science.How important is my majorThe major you choose will neither predict nor guarantee your future. Many graduates find jobs that have nothing to do with what they studied in college. If you intend to earn a professional degree after college, you will probably need certain courses. 13 .When do I choose a majorThis varies widely across schools and programs. 14 . Others require that you decide upon a major by the time that you set foot inside your first class.15Definitely. One of the most exciting aspects of college life is that it introduces you to new subjects and arouses new passions. However,keep this in mind: every major has necessary coursework. If you change your major late in the game, it may take more than the traditional four years to earn a degree.What are minors and double majorsIf one field of study doesn’t satisfy your intellectual appetite, consider a minor. A minor is similar to a major in that it’s an area of academic concentration. 16 A double major provides you with an understanding or two academic fields. It allows you to become familiar with two sets of values and views while it also requires you to fulfill two sets of requirements.A.Can I change my mindB.Is my major time-consumingC.It’s your specialized area of study in college.D.Most students find one major is more than enough.E.Some schools may give you one year or more to decide.F.The only difference is that it doesn’t require as many classes. G.Many future science doctors major in non-science related fields.三、完形填空The year 2020 was a hard year.

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. Sometimes you see very nice clothes, but they don’tfit you because of your body size. 13Doing exercise keeps you thinking quickly at all times. It’s a perfect way of developing the strength of your mind. 14 Besides, there is a reason why most athletes are usually happy. The release(释放)of dopamine (多巴胺) when doing exercise changes their feelings for the better. 15 Run around the blocks each morning, jog or lift weights and see how much good doing exercise does to your m ind.The good of doing exercise every day is endless, but a lot of people pay no attention to it and finally develop lifestyle-related illnesses later in life. So taking exercise is very important and some of the results of not taking exercise are very serious.16 Having fitness goals that mean something to you will help you keep a strict fitness schedule and achieve the result you want. Besides, using fitness trackers, you can monitor your general physical activity and find out whether you have mad e progress.A.Then why is it important to stay fit?B.How can you drive yourself to exercise?C.Setting high goals for exercise is very important.D.Everyone hopes to live a relaxing and comfortable life.E.So keeping your body active improves the work of your brain.F.Fitness exercise will help you lose extra fat and be in great shape.G.Maybe not having enough exercise is the reason for your easy anger.三、完型填空I have a friend named Monty Roberts who owns a horse ranch (牧场).
