现代文阅读阅读下面短文，完成下列小题。

（一）鲁迅说过：“悲剧将人生的有价值的东西毁灭给人看。

”这种毁灭是抗争、拼搏以后的毁灭，抗争与拼搏体现了人的一种精神。

古希腊神话中普罗米修斯为了人类从天上盗取火种，触怒了主神宙斯，被锁在高加索山崖上，每日遭神鹰啄食肝脏，但普罗米修斯毫不屈服，最后坠入深渊。

罗丹的大理石雕塑《马身人首》中，人臂绝望地扑向一个它所抓不到的目标，而马足则陷于尘土不能自拔，表现出人性与兽性的冲突，象征着灵与肉的斗争，具有强烈的悲剧性。

可以说，没有抗争就没有悲剧，冲突、抗争与毁灭是构成悲剧的三个主要因素。

悲剧的审美价值的载体只能是文学艺术。

因为人生有价值的东西、美好事物的毁灭是令人伤悲的，因此现实中的悲剧不能作为直接的审美对象来欣赏，否则人就是泯灭了人性的人了。

现实中的悲剧只能激起人的同情、义愤，迫使人采取严肃的伦理态度和实践行动。

民主革命时期，在演出歌剧《白毛女》的过程中，曾多次出现扮演地主黄世仁的演员被打甚至险遭枪击的事件，这是人们以实际的道德评价代替了审美活动。

现实的悲剧只在客观上具有悲剧的审美性质，它们必须以文学艺术的形式表现出来，才能成为欣赏的对象，美学上所谓的“以悲为美”才能实现。

(摘编自王晓旭《美的奥秘》)下列各项中，其性质不属于原文所论悲剧的一项是A. 中国远征军赴缅甸对日作战局势节节败退，戴安澜将军在带领军队向缅北野人山撤退时腹部中弹，他坚持指挥军队抗战突围，最终伤势恶化，以身殉国。

B. 在电影《狼牙山五壮士》中，五位八路军战士为了掩护大部队撤退及当地群众安全转移，阻击了3000 多名日寇的多次进攻，弹尽粮绝之后，跳下悬崖。

C. 在《孔雀东南飞》中，刘兰芝为守住誓言和爱情，面对焦母的无情拒绝，家人的“威逼利诱”，最后“举身赴清池”，焦仲卿最终也“自挂东南枝”。

D. 老舍笔下的祥子，纯朴善良，勤劳能干，有着骆驼般坚韧的精神，在饱受旧社会、旧制度的沉重打击之后，沦为自甘堕落的行尸走肉。

AMany years ago, when I was in high school I lost my wallet.My old car required to be fueled. I had prepaid and then put my wallet on the bumper(保险杠), and drove off. I hadn’t even had time to miss it when my phone rang and a man asked me if I had lost my wallet. I checked my purse and to my horror, I had. He asked me to tell him how much money was in it, and I told him. He then told me where to pick up my wallet.As I pulled into his driveway, I noticed his wheelchair van and the ramp(斜坡) going up to the house I was thinking that there was no way this man easily got out of his van and got my wallet off the ground. He had to pull over, get in his wheelchair, lower the lift, and then pick it up. I was just amazed.I knocked on the door and he told me to come in. I thanked him for finding my wallet. I was stuck, th ough. While I didn’t want to hurt him by offering money, I really felt like offering something. So I asked him if there was anything I could do to repay his kindness, and he said, “Just pass it on.”It was about 10 years later that I found one. I almost stepped on it when I was shopping at a supermarket! It took my several days to track down the young man to whom the wallet belonged. He was actually surprised his money was still in the wallet and he tried to hand me a $20. I told him, “Thanks, but just pass it on.”1．Where did the author most probably lose his wallet?A．Near a wheelchair ramp. B．At his school.C．At a supermarket. D．At a gas station.2. When the man called, the author ____________.A. hadn’t realized he had lost h is wallet.B. was looking for his wallet anxiously.C. was worried about the money in his wallet.D. was afraid that it would be hard to get his wallet back.3．What can be inferred from Paragraph 3?A．The man was disabled. B．The man failed to pick up the wallet. C．The author regretted what he had done D．The author witnessed the difficulty the man met.4．Why did the author get stuck?A．The man didn’t invite him to take a seat.B．He was wondering how to express his thanks.C．He didn’t know how to repay the man’s kindness.D．He hesitated over how much money he should give the man.BI first began experiencing anxiety and depression when I was a 14-year-old boy after being bullied(欺凌) at school for years. While at first it would come and go, anxiety and depression eventually became a constant presence in my life. It was like a lasting cough that eventually starts to get better, only to come back worse than before. Only unlike a cough, where usually I am still able to function, anxiety and depression hits like a ton of bricks and even the idea of getting out of bed seems to be a goal that gets to be less and less achievable.I tried everything: special teas, yoga, vitamins and anything read about in books and advicegi ven by doctors, but in vain. I started to believe that I’d have to live the rest of my life with this dark cloud. Until one day, I fell upon an article that talked about how dogs were able to help people with their mental health. So I decided to get a dog.When I brought Buddy home, I didn’t realize how much he would change my life. I woke up one morning and felt those familiar feelings again: the weight on my shoulders and the feelings of hopelessness. I knew that the anxiety and depression had come back hard. I didn’t want to get outof bed. That’s when I came face to face with Buddy.Buddy started jumping over me, kissing my face. It was as if he was saying, “It’s no time to be sad. The world is rather frightening!” And for the first time in my life, o n a day when my anxiety and depression was present full force, I got out of bed. I put on my coat and went for a walk in the snow with my new best friend. This was my new beginning.I finally realized the answer to my long question of how to manage anxiety and depression- exercise, laughter and love – all things that were impossible for me before, were achieved by getting a dog.5．How does a cough differ from anxiety and depression according to the author?A．A cough is hard to cure.B．Anxiety and depression often occurs at night.C．A cough can’t stop him functioning.D．Anxiety and depression can easily got rid of.6. How did the author have the idea of raising a dog?A. He read it in an article.B. A doctor instructed him.C. He got if from dog lovers.D. A friend offered him the suggestion.7. What does the author mainly tell us?A. The benefits of raising a dog.B. How he took care of his dog.C. The harmful effect of anxiety and depression.D. How he fought against anxiety and depression.CBy mid-century there will likely be 9 billion people on the planet, using ever more resources and leading ever more technological lives. What will our cities be like? How will we eat? Will global warning cause damaging changes, or will we be able to engineer our way out of the climate crisis(危机)?Changes in where people live will certainly be great. Rockefeller University mathematical biologist Joel Cohen says it’s likely that by 2050 the majority of the people in the world will live in the city, and will have a much higher average age than people today.And rapidly advancing technology will continue ever more rapidly. At the same time, theInternet will continue to greatly change media, destroying the traditional model of what a news organization is.And we’ll live longer and remain healthier. Patricia Bloom, a professor in Mt. Sinai Hospital, says people may not all live to be 120, but is possible that we’ll be able to help people enjoy good health as they age. AIDS research pioneer David Ho says HIV/AIDS will still be with us, but we’ll know a lot more about the virus than we do today and treatments will be much more effective. At the same time, Jay Parkinson, the founder of Hello Health says the health care industry has a huge opportunity to change the way it communicates with patients by imagining individual health in relation to happiness.In terms of how we’ll eat, green markets founder Nina Planck is optimistic that there will be more local food operations and we’ll be healthi er as a result. He thinks people will eat fewer processed foods, and eat foods grown closer to where they live. Besides, more people will grow and preserve land-raised farm systems.8．How does the author introduce the topic?A．By listing numbers.B．By asking questions.C．By predicting changes.D．By showing background9．According to the text, which of the following will happen by 2050?A．Fewer people will live in urban areas.B．The Internet will no longer affect media.C．People will generally live for over 120 years.D．People will have a better knowledge of HIV virus.10．In Nina Planck’s opinion, what will people do in the middle of this century?A．They’ll stay away from processed foods.B．They’ll grow food by themselves.C．They’ll eat locally p roduced foods.D．They’ll eat more highly processed foods.11. What can be the best title for the text?A．What will life be like in 2050?B．Technological advances in 2050C．Great changes to happen in 2050D．How will the society develop in 2050?DVal entine’s Day is one of those rare holidays that are enjoyed by almost everyone in the world. But how did it begin? While there are many legends(传说), the most popular one dates back to 270 AD. According to the legend, Emperor Claudius II, the ruler of the Roman Empire did not allow young men to get married before heading to war. He believed that single men made better soldiers because they were more focused.But a Roman clergyman(牧师) named Valentine did not agree and helped many couples get married secretly. When the Emperor found out, he sentenced him to death. While in prison, Valentine fell in love with a girl and just before he was executed on February14, he sent her a note signed-‘From Your Valentine’. In 496 AD Pope Gelasius set aside the day to honor S t. Valentine and a fun tradition was born!The Pope, of course, was not the one who changed it into a commercial(商业的) holiday. That credit goes to Richard Cadbury, a member of the famous British chocolate company, and Massachusetts business-woman Esther Howland. The former came up with the brilliant idea of selling bite-sized chocolates packaged in heart-shaped boxes.Candies and cards remain the biggest Valentine’s Day gifts till this day. Americans spend over $1 billion on chocolate. Also popular, are sweethearts. According to the manufacturers plenty of the 8 billion candy conversation hearts made annually are sold between January 1 and February 14.With over 145 million cards exchanged in the US and over a billion worldwide, Valentine’s Day is one of the biggest moneymakers for greeting card companies. It is second only to Christmas when 2.6 billion cards are sold. Flowers are also very popular. About 51% of people, primarily men buy red roses for their loved ones.12．Why didn’t Emperor Claudius II let young men get married before heading to war?A．He liked single men more than married men. B．He thought single men were easily distracted.C．He thought single men could become better soldiers. D．He thought single men were braver than married ones.13. What does the underlined word “executed” in Paragraph 2 mean?A. Praised.B. Killed.C. Beaten.D. Admired.14．What can we know from the text?A．The re are more cards sold on Christmas than on Valentine’s Day.B．The Pope changed the holiday into a commercial one.C．Valentine was killed because he got married secretly.D．Most of the greeting cards are bought for parents.15．What is the main idea of the text?A．How to choose Valentine gifts.B．The most popular gifts on Valentine’s Da y.C．How to make money on festivals.D．The brief history of Valentine’s Day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。

Here are some recommended to you. Notting HillAfter the success of his film Four Weddings and a Funeral, writer and producer Richard Curtis captured the essence of being British in 1999’s Notting Hill. Set against the background of affluent (富足的) West London, the film became popular for its charming and funny portrayal(刻画) of a British nobody trying to impress a Hollywood star.The Full MontyThis 1997 film is a Sheffield-based comedy about six unemployed men who form a group to make money for a better life. Despite its hummer, the film dives deeper into some serious issues surrounding working-class culture. The Full Monty is an uplifting film that gives an insight into the work and life of the working class in Britain.TrainspottingDanny Boyle’s 1996 comedy-drama Trainspotting is about a group of Scots in the 1980s, based on the book by Irvine Welsh. With a cast of truly great actors including Ewan MeGregor, the tale impressed the audience globally. It rapidly became a critical success. Monty Python’s Life of BrianFeaturing a jam-packed cast of comedic stars. Monty Python’s Life of Bria n tells the story of a young man who is in a case of mistaken identity. The film reflects the unusual and wonderful British sense of humour. As a film guaranteed to entertain, Monty Pythons Life of Brian is not to be missed by those looking for an insight into what makes the British laugh. 26．What can the audience learn about by watching The Full Monty?A．Hardships of comedic stars B．Daily life of people in West LondonC．Unique experiences of some Scots.D．Life of the British working class. 27．What kind of film does Monty Python’s Life of Brian belong to?A．A comedy film.B．A science fiction film.C．An action movie D．A horror movie.28．Which of the following films is adapted from a book?A．Notting Hill.B．The Full Monty.C．Trainspotting.D．Monty Python’s Life of Brian.When Roy Austin went on his first wildlife trip back in 2018, his only goal for the leisurely vacation was to catch sight of some African wildlife in its natural habitat—but he ended up finding something much more meaningful. He was most captivated (迷住) by the people he met in rural Kenya—particularly at the Amboseli Primary and Secondary School in Amboseli National Park.In addition to befriending many of the students and teachers, Austin was surprised to learn how difficult it was to get books and school supplies for the children. “In rural Kenya, the government does not build school buildings. You either build it yourself or raise money to have it built,” says Austin. “A teacher was asked if they had a library. She replied, ‘ No, but we would love to have a library.’ That stuck in my mind.”When Austin eventually returned to his home in Bluffton, South Carolina, he launched Libraries for Kids International. Since starting the charity, Austin has managed to ship more than 1000 books to 11 schools across Kenya and Tanzania. He sends the books through the post office rather than FedEx to keep the shipping costs down.As it continues to collect books and donations for additional shipments, Austin says that the charity is now helping to move a shipping container of 22, 000 books from Atlanta to Kenya. In the future, the philanthropist (慈善家) hopes to start sending donations to South America as well.“Many people told me that it can’t be done. It’s too expensive to ship books, and they will disappear going through customs,” Austin says. “However, every worthwhile project will have problems and barriers. If you focus on the problems, you will never start. On the contrary, if you focus on the aim and solve the problems as they arise, most anything is possible.”29．What problem does Austin find in rural Kenya?A．Education depends on charity.B．Students lack education resources.C．Books get lost going through customs.D．Families can’t afford the kids’ schooling.30．What does Austin do for the people in rural Kenya?A．He teaches at school.B．He funds a library for them.C．He reduces the shipping costs.D．He ships books to schools.31．What can we learn from Austin’s story?A．It is the first step that costs.B．Success belongs to the persevering.C．Every bit of effort makes a big difference.D．Nothing is difficult to a determined mind.32．Which of the following best describes Austin?A．A crazy adventurer.B．A devoted educator.C．A charity enthusiast.D．A passionate volunteer.Under normal circumstances, falling asleep during a paid tour is a waste of money or an offense to your guide at worst. But that’s not the case with this new experience coming out of Hong Kong. As its name suggests, the Sleeping Bus Tour is designed to help passengers catch some sleep, and rides are already selling out.A 2022 survey by the Chinese University of Hong Kong’s Center of Communication and Public Opinion notes almost 70% respondents experiences some form of sleep disorder. Hong Kongers have much stress from work and need a space for sleeping, but their living spaces are too small. Some may not live alone and have to share apartments with their family, which may not be a good environment for a proper rest.After noticing passengers falling asleep on their buses, the Hong Kong tour company, Ulu Travel Agency, recently launched such an innovative way for adults to sleep: the Sleeping Bus Tour. The five-hour bus ride takes passengers on an 83-kilometer(about 51.5 miles)journey aboard a regular double decker bus. Not only is the Sleeping Bus Tour the first of its kind, it’s also the longest bus route in Hong Kong, ensuring that tired passengers have plenty of time to enjoy some sleep.Once passengers board the bus, they are treated with a goodie bag complete with an eye mask and earplugs to help them sleep and they are allowed to bring their own blankets and slippers. The long ride includes a few stops for scenic spots and bathroom breaks. Passengers can also get off the bus early at one of several drop-off points if they’d prefer to continue theirsleep at home rather than complete the entire journey. Tickets for the Sleeping Bus Tour are divided in four categories from the “Zero-decibel(分贝)Sleeping Cabin“ to the ”VIP Cabin.” Prices range from about $17 USD to S115 USD per person. For more information on this unique experience, head to the Ulu travel company website.33．What does the survey show?A．Hongkongers desire to live alone.B．Hongkongers can afford paid tours.C．Hongkongers are under extreme stress.D．Most Hongkongers have troublesleeping.34．Why was the Sleeping Bus Tour launched?A．To improve the sleeping habits.B．To make more profits.C．To reduce the stress from extra work.D．To help adult passengers rest properly. 35．What can a passenger get from the Sleeping Bus Tour?A．A ride in a high-tech bus.B．A guided sight-seeing tour.C．A bag with sleep aid products.D．A blanket and a pair of slippers. 36．What is the purpose of the text?A．To introduce a bus tour.B．To inform readers of a new survey.C．To advertise a travel company.D．To raise concerns over sleep problems.Young children are significantly more likely than adults to have their opinions influenced by robots, according to a new research. The study, conducted at the University of Plymouth, compared how adults and children respond to an identical task when in the presence of both their peers (同龄人) and robots.It showed that while adults regularly have their opinions influenced by peers, something also demonstrated in previous studies, they are largely able to resist(抵制) being persuaded by robots. However, children aged between seven and nine were more likely to give the same responses as the robots, even if they were obviously incorrect.The study asks people to look at a screen showing four lines and say which two match in length. When alone, people almost never make a mistake but when doing the experiment with others, they tend to follow what others are saying.When children were alone in the room in this research, they scored 87% on the test, but when the robots join in their score drops to 75%. And of the wrong answers, 74% matched those of the robot.Professor Belpaeme said, “People often follow the opinions of others and we’ve known for a long time that it is hard to resist taking over views and opinions of people around us. But as robots will soon be found in the home and the workplace, we were wondering if people would follow robots.”“What our results show is that adults do not follow what the robots are saying. But when we did the experiment with children, they did. It shows children can perhaps have more of an affinity (亲和力) with robots than adults, which does pose the question: What if robots were to suggest, for example, what products to buy or what to think?”37．What did the adults do when staying with robots?A．They totally accepted the robots’ suggestions.B．They tried to persuade robots to resist them.C．They generally refused the robots’ effects.D．They usually compared robots with their children.38．Why did some children make more mistakes in the experiment?A．Because robots in the presence made mistakes.B．Because children were not as clever as the adults.C．Because robots reflected better than human beings.D．Because children wanted to affect the robots on purpose.39．What is Professor Belpaeme’s attitude towards the result of the experiment?A．He is optimistic about the result.B．He doubts the result of the research.C．He doesn’t care about the result.D．He is worried about the future. 40．What should be followed after the last paragraph?A．What is the meaning of the research?B．What will be done to solve the problem?C．What should adults do to avoid the problem?D．Why are children more likely to be influenced?三、七选五An indoor garden has a positive impact on your life if you take care of them properly. However, if you fail to plan before starting one on your own, you may end up with a fewSun ConditionsPlants need an ample amount of sunlight for them to grow properly. 42 Before starting an indoor garden, make sure you’ve conducted a few weeks’ worth of observations about how sunlight behaves inside your home at different times of the day. This will give you an idea as to where your indoor garden is.Space AvailabilityObviously, the sun conditions would be useless if you don’t have enough space for the garden. That said, consider where the sunlight lands. You must also determine whether you can place a garden there. 43 Do it in such a way that you get to accommodate (考虑到) your plants ‘sunlight needs while also maximizing the space of your home for other things.BudgetYou will spend a few dollars if you want to start an indoor garden. That’s a fact. This shouldn’t bother you, though. 44 The money you spent on gardening essentials will return in the form of not having to buy certain things in the market because you have one at home. Before starting an indoor garden, consider the budget you want for the garden. This will determine the containers and types of plants you can cultivate.The world will always present us with many problems that can affect us physically, mentally, and emotionally. One great method for achieving a healthy lifestyle is by growing a garden. 45 Thanks to indoor gardening, you can have a slice of paradise in the city.A．If not, you can try rearranging your home.B．To avoid that, you need to consider a few things.C．That means you should consider the availability of sunlight.D．Without enough sunlight, all living things wouldn’t survive.E．Besides, you must consider how to shelter your garden in the sun.F．That’s because, in the long run, indoor gardens are actually money-savers.G．Living in the city is not a problem for people with green fingers anymore.四、完形填空My daughter had talent for acting.

On the one hand, we assume that we are indestructible. On the other, we think that any damage we impose on ourselves can be undone when we finally clean up our act.If the evidence for how wrong the first idea is isn't apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?To a surprising degree, the answer is yes. Over the past five years, scientists have accumulated a wealth of data about what happens when aging people with bad habits decide to turn their lives around. The heartening conclusion: the body has an amazing ability to heal itself, provided the damage is not too great.The effects of some bad habits--smoking, in particular--can haunt you for decades. But the damage from other habits can be largely healed. “Any time you improve your behavior and make lifestyle changes, they make a difference from that point on”, says Dr. Jeffrey Koplan. “Maybe not right away. It's like slamming on the brakes. You do need a certain distance”.But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research:--A study concluded that women who consume as little as two servings of fish a week cut their risk of suffering a stroke to half that of women who eat less than one serving of fish a month.--The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline。
