We placed a sign alongside the railwhich read: "Are you cold? Take one. Like tohelp? Leave one. " What happened next wasremarkable.By the aftemoon the clothes rail was almostfull. People near Exmouth Market had donated jackets and coats as well as gloves,hats and blankets and passing homeless people were helping themselves to whatever they needed.As well as the clothes rail,people donated "pledge cards" which offered homeless people free food,drinks and other services. Jeremy Brill,owner of Brill Cafe,has found that the pledge cards are popular with customers. "If a customer gives us ~5,we put it on a pledge card and leave it by the rail where a homeless person can use it to buy a hot drink or a sandwich. " Ellie Pamphilon,who runs a barbershop,has also been enthusiastic about the project. There are also ambitious plans to digitalize the pledge card scheme so that people will be able to pledge meals to homeless people from the comfort of their living rooms.One month on,and our rail in Exmouth Market is not only still going strong but,thanks tomedia coverage and a growing social media presence, has spawned similar activities aro un d Britain and beyond.Like any social action project,we wanted our rail to bring about change,to benefit those individuals less fortunate in our community. And that benefit is twofold. Being a volunteer on a social action project can improve your confidence and levels of wellbeing.So,.get involved by asking what you can do for your community, not only what your community can do for you.25. What do we know about " pledge cards"?A. They have been made into digital ones.B. They are worth ~5 each in Brill's Café.C. They offer the homeless warious services.D. They were first started by Ellie Pamphilon.26. What does the underlined word "spawned" in paragraph 4 mean?A. set off.B. kept up.C. held back.D. left behind.27. Why does the author say "And that benefit is twofold" ?A. The project does good to the homeless and the volunteers.B. The project is useful to the individuals and the community.C. V olunteers can improve confidence and levels of wellbeing.D. Changes have taken place in the community and social media.28. What is the author's purpose in writing the text?A. To advertise a new business.B. To show their love for charity.C. To entertain readers with a story.D. To inspire readers to help the community.CMost of the world's progress is made by the few pioneers who break barriers,reach new distances,and find a new path. They are the few brave enough to believe in the seemingly impossible and dedicate themselves to make it possible. Once they do this,they open the gates for others to follow.A powerful demonstration of this is Roger Bannister,who in 1954,broke the four-minute mile barrier with a record of 3 minutes,59.4 seconds. Before Bannister succeeded,the prospect was considered not only dangerous but impossible. But Bannister did not limit himself by this way of thinking; he developed within himself a certainty that it was achievable; even though there was no evidence to suggest it. In fact,there was a lot of evidence to suggest it wasn't achievable. But his belief to the contrary allowed him to train for years to his end goal.On 6 May,1954,Bannister's remarkable achievement created a new wisdom. Just 24 days later,the barrier was broken again and in the last 50 years,more than 1,000 other runners have achieved the feat.It was not that these runners had enhanced physical qualities from the run ners who had tried and failed before them,but that they had enhanced psychological qualities. They had proof of the possible.Sometimes we do need to see it to believe it. But if we are limited to stories of problems and failures,it can be difficult to see beyond them. Those people who achieve extraordinary things do not accept the current standards; they break the barriers of' what is'and push beyond them to 'what could be: It is through learning from those who force progress into existence that we too can realize our own potentials - to be a powerful force for good.29. What does the underlined word "this" refer to in paragraph 2?A. Finding a new path.B. Being a pioneer.C. The world's progress.D. The 4-minute mile barrier.30. What do we know about Roger Bannister?A. He wanted others to follow him.B. He made a breakthrough in running.C. He received support from his family.D. He collected evidence to support himself.31. Why are " other runners"mentioned in paragraph 3?A. To show the bravery of other runners.B. To confirm the significance of pioneers.C. To illustrate the power of following others.D. To state the importance of physical qualities.32:What does the author advise the readers to do in the last paragraph? 'A. Ignore the barriers.B. Learn from failures.C. Fulfill the potentials.D. Accept the existing standards.DThe skin on your hands and feet is noticeably different from that on most other areas of your body. Unlike those other areas,the 8kin on your palms and soles doesn't have hair. And when you bathe irt water,most of your skin looks normal while your hands and feet wind up looking like wrinkled (起皱的) prunes.Another way in which your hands and feet are different is that both the palms and soles have unique patterns of ridges,also called fingerprints and footprints. The middle layer of skin connects to the epidermai (表皮的) layer through many papillae,which are tiny fingerlike Projections (突起）of connective tissue. Fingerprints and footprints have purposes other thanhelping experts to solve crimes; they help you to grab on to objects,and they help to keep your skin from being torn.In addition to lacking hair and having ridges,the skin on your hands and feet is also thicker. With all the tasks these body parts have to perform,such as walking or picking things up,they tend to get a lot of use. As a result,the thicker,hairless skin allows them to bear more friction (摩擦) without getting damaged. Part of that extra thickness is caused by a kind of protein,which gets nutrients in deeper layers of the skin but forms a surface layer of dead cells on the epidermis. This extra thickness may also explain why your hands and feet become wrinkled when you bathe in the water. The dead protein cells absorb the water so that the thin surface layer of skin expands and then wrinkles.33. What is the best title of the text?A. Skin layers tell your body code !B. Why skin differs across your body?C. Why skin on hands and feet different?D. Skin on hands and feet says your health !34. Why can the fingerprints and footprints help solve crimes?A. They are not easy to tear.B. They have unique pattems.C. They help grab on to objects.D. They are fingerlike by nature.35. What might contribute to the extra thickness of the skin?A. Tiny ridges.B. More nutrients.C. Frequent use.D. Connective tissue.36. What makes your hands and feet wrinkled in the water?A. The shortage of protein cells.B. The lack of hair on the surface.C. The damage of the deeper layer of skin.D. The expanding of the surface layer of skin.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。

福建省莆田第一中学2023-2024学年高二下学期期中考试英语试题一、阅读理解Chocolate is delicious, we all know that. But it isn’t just for eating, as these chocolate works of art clearly show.Chocolate couchIn 2009, chocolate company Galaxy used 250kg of their own chocolate to make a chocolate couch. The couch was part of their “Irresistible Reads” campaign, which was designed to arouse interest in books. It was put on display in Victoria Embankment Gardens in London. Photos were taken of British TV actress Emilia Fox sitting on the couch reading a book.Chocolate mailboxIn 2011, seven artists from New York built a chocolate mailbox decorated with white truffle hearts to celebrate Valentine’s Day. The mailbox was on display on Fifth Avenue. People could post their love letters there, and the post office would stamp and mail them for free during the three weeks leading up to February 14.Chocolate wallA wall of chocolate at a railway station in Utrecht, the Netherlands became many food lovers’ new place to mark in 2019. The whole wall was made of chocolate, making it very fun, good-looking, and of course, delicious. Viewers were encouraged to touch, smell and taste it, interpreting the artwork in their own ways.Chocolate shoesOne of London’s greatest chocolates, Phil Neal once created a collection of high-heeled shoes made of chocolate. Neal used top-quality Venezuelan chocolate, filled the shoes with gauche and strawberries, and decorated them with 22-carat gold. The shoes were on sale at London’s luxury chocolate shop Theobroma Cacao.1．Why was the chocolate couch made?A．To display a product.B．To promote reading.C．To celebrate an occasion.D．To recommend gardening.2．On which day could a letter be posted free via the chocolate mailbox?.A．January 29.B．January 5.C．February 18.D．February 25. 3．Which of the following was for sale?A．The chocolate couch.B．The chocolate mailbox.C．The chocolate wall.D．The chocolate shoes.When Param Jaggi was five years old, he had a passion to take things apart to see what was inside. He started with toys and even broke a computer, which made his parents not too pleased. As he got older, he shifted from breaking things to building things, which greatly comforted his parents. In middle school, he started working on projects in his kitchen laboratory, and his first project was making biofuels.Although Jaggi’s parents initially thought his experiments were just a boyhood fancy, he remained determined to make a difference to the environment. Eventually, his parents came around and started supporting his dreams. Jaggi’s interest continued as he grew up, but he focused more on solving real problems, especially those related to the environment.At 17, Jaggi went beyond his school projects and co-founded Ecoviate, a company that uses technology to solve everyday energy and environmental problems. He planned to transform people’s idea that going green is expensive, by making available a series of affordable products that are easy to use. Through Ecoviate, he designed products that could contribute to a greener future. One of his notable inventions was the “CO2ube”, a device that could reduce carbon emissions, and it’s available to many people at low prices.Young Jaggi, now a third-grade college student studying engineering and economics, has become a famous eco-innovator and his company is developing promisingly. However, Jaggi’s vision to save the environment goes beyond creating products. He plans to launch an online platform through Ecoviate, which will encourage young students interested in science and technology to get actively involved in innovation and invention. Students can submit a science project online, and talk about the help that they need to make the project a reality.4．What can we learn about Jaggi?A．He dreamed to be an engineer.B．He was curious by nature.C．He always annoyed his parents.D．He was addicted to playing toys.5．Which of the following can best replace the underlined part “came around” in Paragraph 2?A．Walked around.B．Paid a visit.C．Changed their minds.D．Become conscious.6．What drove Jaggi to develop affordable and user-friendly products?A．His love for greener devices.B．His pursuit of academic career.C．His hope to boost green industry.D．His desire to make a difference.7．Why does Jaggie plan to launch an online platform?A．To empower young inventors.B．To promote smart products.C．To provide eco-themed courses.D．To offer environmentalists funds.A new study led by researchers at the Yale School of Public Health finds air pollution may negatively impact standardized test scores. Using data from the North Carolina Education Research Data Center, the researchers tracked 2.8 million public school students in North Carolina from 2001 to 2018 and measured their exposure to PM2.5 found in polluted air. While previous research has shown negative effects on academic performance, it has relied on relatively small or less representative samples. “The biggest strength of this study is that we tracked every student in North Carolina in those years, for the whole time period that they were in the public schools,” said Emma Zang, coauthor of the study.The study also finds that test scores of ethnic minorities and girls are disproportionately (不成比例地) impacted by PM2.5 levels. “Females and ethnic minorities face sexism and racism,” said Zang. “There are a lot of policies that are not friendly towards them. So, when they’re exposed to the same level of air pollution, they don’t have the resources to lessen the negative influences.” More privileged populations, however, might have more resources that allow them to live in a better environment, such as in houses with air purifiers.“The level of PM2.5 pollution in the US is relatively low, but students living in areas below the current air quality standard of annual PM2.5 concentration are still negatively impacted by air pollution when it comes to their test scores,” said Zang. “We should aim to strengthen the annual PM2.5 standard to better protect our children.”Air pollution is known to contribute to disease and death, and it also negatively affects students’ academic performance even at low levels of pollution. The subsequent studies, theresearchers said, would involve looking at whether the findings hold true in different areas, and also the reasons behind the ethnic and sexual differences.8．What’s the greatest advantage of the study?A．Tracking each student for 18 years.B．Collecting more comprehensive data.C．Measuring students’ PM2.5 exposure precisely.D．Building links between airpollution and test scores.9．According to Zang, ethnic minorities and girls ________.A．benefit from current policies on PM2.5 pollutionB．have the lowest test scores due to their identitiesC．lack resources to reduce the impact of air pollutionD．suffer from educational inequalities owing to their background10．What’s Zang doing in paragraph 3?A．Offering a suggestion.B．Raising a doubt.C．Making a comparison.D．Giving a prediction.11．What might be the focus of the follow-up studies?A．Applicability of the findings to other regions.B．Ways to address racial and sexualdifferences.C．Long-term impacts of air pollution on children.D．Establishment of PM2.5 standard fit for children.Today, poetry and science are often considered to be mutually exclusive(互相排斥)career paths. But that wasn’t always the case. The mathematician Ada Lovelace and the physicist James Clerk Maxwell were both accomplished poets. The poet John Keats was a licensed surgeon. Combining the two practices fell out of favor in the 1800s. But translating research into lyrics, haiku, and other poetic forms is resurging(再现)among scientists as they look for alternative ways to inspire others with their findings.“Poetry is a great tool for questioning the world,” says Sam Illingworth, a poet and a geoscientist who works at the University of Western Australia. Through workshops and a new science-poetry journal, called Consilience, Illingworth is helping scientists to translate their latest results into poems that can attract appreciation from those outside of their immediate scientificfield.Stephany Mazon, a scientist from the University of Helsinki in Finland, joined one of Illingworth’s workshops. In the workshop, she was grouped with other scientists and tasked with writing a haiku, a 17-syllable-long poem, which spotlighted water, a fluid that featured in all of the group members’ research projects. “It was a lot of fun, and surprisingly easy to write the poem,” Mazon says. She plans to continue writing. “We do a disservice(伤害)to ourselves to think that scientists can’t be artistic and that art can’t be used to communicate scientific ideas,” Mazon says.That viewpoint is echoed by Illingworth, who thinks science communication initiatives are too often dominated by public lectures with their hands-off PowerPoint slides. “Actually, when science communication involves writing and sharing poems, it invites a two-way dialogue between experts and nonexperts,” he says. Scientist-poet Manjula Silva, an educator at Imperial College London, agrees. Poetry provides a way to translate complex scientific concepts into a language that everyone can understand, Silva says.Scientists and poets are both trying to understand the world and communicate that understanding with others. The distinction between scientists and poets is less than people might think. We’re all just people with hopefully really interesting things to say and to share. 12．What is the purpose of mentioning the celebrities in paragraph 1?A．To display they were talented.B．To confirm they were out of favor.C．To encourage different career paths.D．To show poetry and science can be combined.13．What are Illingworth’s workshops aimed to do?A．Promote a new science-poetry journal.B．Inspire outsiders to pursue their careers in science.C．Encourage science communication through poems.D．Get scientists to exchange ideas about the latest research.14．What does Illingworth think of the dominant ways of science communication?A．Conventional.B．Effective.C．Innovative.D．Complex. 15．Which of the following is the best title for the text?A．Scientists Take on PoetryB．Scientists and Poets Think AlikeC．Poetry: A Great Tool to Question the WorldD．Science Communication: A Two-way DialoguePerhaps you’ve stopped doing what you want because you’re afraid of what others think of you. You feel that you must do what they expect and that you must meet their expectations, otherwise you’ll lose their approval. 16 Then, you’ll be able to do what you want freely.Think about yourself, about what you really like and are interested in. You must lead your life independently.17 However, you might feel afraid to do it because you’ ve always done everything to gain the approval of others. You need to get out of that zone, move to new places, and explore your full potential.By surrounding yourself with people who think like you, you’ll realize that you don’t feel judged. Then, you’ll start doing what you really want. 18 Your new friends will integrate into your life and you’ll also keep your genuine friends. On the other hand, those who are always ready to see the negative and question what you’ re trying to do will drift away.To overcome your fear of what others think and of their non-approval, you should start talking about your plans, For instance, you might want to tell a handful of friends about your wishes and dreams. 19 You’ll feel confident in yourself and you’ll be able to go on your new path without any fear.It’s unavoidable that not everything will be plain sailing, and you’ll find obstacles along your way. 20 People in your environment often don’t understand what you do no matter how much you explain it, so ignore them.A．There is no need to think about what you want.B．You don’t have to change your circle of friends.C．Your life belongs to you, as well as your actions.D．By talking to them, you’ll be able to organize your plans and ideas.E．If this is the case, it’s time to start working on your self-esteem (自尊).F．You must do what you want without being affected by what others think.G．However, you must trust in yourself and seek the necessary strength to move forward.二、完形填空At a family picnic for employees of the company where my father worked, they held a contest for children.

All right, I figured, this is California, where drought (干旱) is a concern. But then more followed. Not to leave my awkward walking shoes sitting out, and did I even need such ugly footwear? Don’t wear a neck warmer when walking the dogs in the morning — it will warm up when we get to the park. And do you have to take a shower before we drive to Topanga?At the beginning, I wondered how I raised such a bossy child. But I recalled my own words when he was young: “Someday, you’ll have your own home and can live however you want. Until then, do as we say.” Now, it was payback time.I remembered being angry at my own father’s commands growing up, how he always tidied my desk or came into my room at dusk to close the windows. And so I smilingly followed Nathaniel’s nagging (唠叨).On our last afternoon, we were walking along ElMatador Beach and hit an extended patch of rocks — clearly the end of the line, I thought. Nathaniel wouldn’t hear of it and encouraged me to walk across one largest one to the next, patiently telling me where to place my arthritic (关节炎的) feet and hands as ocean waves came close. I was terrified, but after a couple hundred yards we eventually reached a fresh sandy beach.“You did it! I’m really proud,” he said, smiling, as if I’d just learned to ride a bike. It was then that I knew for sure that the son also rises to fatherhood.4．What does the underlined word “admonished” in paragraph 2mean?A．Warned gently but firmly B．Explained loudly but lovingly.C．Announced officially and clearly.D．Inspired deeply and indirectly.5．Why did the author refer to his father?A．For memory.B．For reference.C．For encouragement.D．For comparison. 6．What was the writer’s attitude towards his son at last?A．Annoyed.B．Regretful.C．Appreciative.D．Disapproving. 7．What might be the best tile of the passage?A．The Role Switch: Parent to PupilB．The Bossy Son: Nathaniel’s TakeoverC．The Beach Challenge: Crossing the RocksD．The Power of Words: Nagging to ChangeThere are millions — possibly billions — of ponds (池塘).Yet for a century or so, they are poorly understood and scientists have paid them very little attention. This neglect (忽视) might not have mattered if it were not for increasing evidence that ponds are extremely important habitats for wildlife.Ponds are being shown more bio-diverse than rivers or lakes. Interestingly, this seems to be partly due to the small size of ponds, which allows them to have a wide range of conditions. The community in a pond with clear water will be very different to that in a nearby seasonal pond made cloudy by farm animals. Ponds show far greater variation than rivers and streams, as flowing water tends to equalize water chemistry.So why have we ignored such a vital part of the natural world? A key reason appears to be the bias (偏见) we humans have where we assume that if something is small, it can’t be all that important. Rather than study ponds, scientists in the past typically headed for the largest lake or river they could find.Most of us also devalue ponds because we assume they are artificial habitats: we look at the human-made examples around us and don’t realize that these waters have a deeply ancient origin. In our new book Ponds, Pools and Puddles, we show that ponds have clearly existed on Earth as long as there has been land and water and the geological record shows they have been a constantpresence.Now, views are taking on new shapes. Last year, the Ramsar Convention, an international agreement, introduced a proposal on small wetlands, including ponds, giving crucial recognition to them. And the European Union-funded PONDER FUL project is gathering data on Europe’s ponds.In a world where freshwater faces big challenges, creating and protecting ponds provides a ray of hope: a piece of natural ecological (生态的) engineering we can easily achieve to help support one of the most threatened bits of the environment.8．What may contribute to the biodiversity of ponds?A．The nearby animals.B．The constant temperature water.C．Their diverse conditions.D．Their regularly changing conditions. 9．What caused ponds to be neglected?A．People’s love for nature.B．Insufficient ponds for research.C．People’s mistaken belief of ponds.D．Lacking scientific research methods. 10．Why is “PONDERFUL project” mentioned?A．To promote the Ramsar Convention.B．To prepare for the research on pondsC．To highlight the importance of small wetlands.D．To show the changing attitudes towards ponds.11．What can we conclude from the last paragraph?A．Penny wise, pound foolish.B．A small key opens a big door.C．Small streams make great rivers D．A bird in the hand is worth two in the bush.We all know how it feels to get lost in a great book. Sometimes the characters and emotions can seem as real as those of our everyday lives, But what’s happening in our brains as we dive into those pages?A team led by Leila Wehbe and Tom Mitchell of Carnegie Mellon University’s machine learning department has provided answers to the question.The researchers gathered a group of 8 volunteers, and recorded their brain activity in an fMRI scanner(扫描仪) as they read Chapter 9 of Harry Potter and the Sorcerer’s Stone for 45minutes. Then, they put the volunteers’ fMRI data into a computer program they’d written. They’d designed the program to look for patterns of brain activity that appeared when the volunteers read certain words, particular characters’ names and other features of the story—a total of 195 different “story features”.When the researchers used all the 195 story features, the program was able to guess which passage was being read with an accuracy of 74 percent. Finally, the researchers repeated the test at every brain region, which allowed them to figure out which brain regions are processing which types of information.They find that our brains run individual words through the first round of processing in the visual cortex—the brain area that processes all visual input—and through higher-level processing areas like the left inferior frontal gyrus (左侧额下回). When the volunteers read descriptions of physical movement in the story, the descriptions adjusted the activity into the regions involved in sensing real-world movement. A variety of characters, meanwhile, were correlated with the activity patterns in the right posterior superior region (脑右后上区域). This all confirm the existence of what researchers call the “protagonist’s perspective(主人公视角)interpreter network(PPIN)”, a network of brain regions that enable us to “become” the protagonist of the story we’re reading.“We maybe not only toward a more accurate rate neural(神经的)model of language processing, but also toward a clearer understanding of how and why it can go wrong,” We h be said. Someday it may help us design individually tailored neurological treatments for reading disorders. And many people may in the future find it easier to get lost in the pages of a good book. 12．How was the study carried out?A．By using an fMRI scanner.B．By reading the book and telling feelings.C．By tracking the brain’s response to a story.D．By processing the book with a program.13．Why did the researchers repeat the test at every brain region?A．To test its effect.B．To improve the program prediction.C．To confirm “story features”.D．To identify brain’s processing regions. 14．What can we know about the findings of the study in paragraph 5?A．Readers can experience the story through PPIN.B．Higher-level processing areas are for storing words.C．Physical movements are processed in the inferior frontal gyrus.D．Characters are associated with the left posterior superior region.15．What is a possible application of the study?A．Promoting good reading standards.B．Improving humans intelligence.C．Curing people’s reading disorders.D．Mastering learning skills easier.Unaided, we can’t do anything without our feet. So why, when our quality of life is directly related to being active, do many of us ignore these two vital parts of our body?16 In 2021, a study over arise in foot tissues and how poor foot health affects everything from physical activity to the overall health of able-bodied people was conducted. “Foot problems can reduce quality of life, lead to loss of balance, make it difficult to put on shoes and increase the risk of falling,” the authors wrote in the journal Scientific Reports. Meanwhile, a 2017 study, also in Spain, of able-bodied university students confirmed this too. 17 It increased their risk of being socially cutoff.If foot pain limits your activity a and lasts more than a week, says Paul Langer, a sports-medicine podiatrist (足疗医生), it’s time to see a doctor for foot treatment. 18 They’re like the base of the Tower of Pisa. When they’re off, the tower leans (倾斜).Therefore, keeping our foot happy is rather critical. 19 Experts say every move we make creates a chain reaction in our muscles, and joints.The foot is the driver of all movement. 20 If afoot doesn’t work normally, it can drive everything up the chain to be of disfunction, too. The key to a healthy foot is strength and mobility through the hips (臀部). Therefore our feet need help from their friends above to keep them working properly.A．Spanish scientists expressed concern.B．All of this can affect activities of daily living.C．In fact, seeking help from experts is the best way.D．Poor foot health prevented them from being physically active.E．Taking care of your feet sometimes begins elsewhere in your body.F．When the foot hits the ground, everything else in the body changes.G．If the feet aren’t performing properly, they throw everything else off.二、完形填空It was one of my favourite parts of the day, when I walked my husky, Max, around our neighbourhood.Though wolf-like in 21 , he was a teddy bear at heart.

For many years, I had a recurring (重复出现的) dream. I was a little girl again, rushing about, trying to get ready for school.“Hurry, you'll be late for school,” my mother called to me.“I am hurrying, Mom! What did I do with my books?”Deep inside I knew where the dream came from. It was about some unfinished business in my life. As a kid, I loved everything about school. I loved books, teachers, tests and homework. Most of all 1 longed to someday march down the aisle (通道) to receive my diploma. That seemed more appealing even than getting married.But at 15, I had to drop out because my parents couldn't afford tuition. My hope of getting a diploma(毕业证书) was dead, or so I thought. Pretty soon, I married and had three children, and I thought: “There goes my diploma.”Even so, I wanted my children to be educated. But Linda, our youngest child, had juvenile arthritis (幼年型关节炎) in her hands and knees, which made it impossible for her to function in a normal classroom. I felt really sorry for her and I didn't want her to live her life with regret. I didn't give up hope of her being back to school in some way.One day, I saw an ad in the newspaper for evening cours es. “That's the answer,” I said to myself. Linda always feels better in the evening, so I'll just sign her up for night school.Linda was busy filling out enrollment (入学) forms when the secretary said: “Mrs. Schantz, why don't you come back to school?”I l aughed: “There's no way! I'm 55!” But he persisted, and before I knew what I had done, I was enrolled for classes in English and crafts. “This is only an experiment,” I warned him, but he just smiled. So, I told myself to try for just a semester and to see if it would work. Anyway, my dream was still there in my heart.Paragraph 1:It was exciting to go to school again but it was no game.__________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ _________________________________Paragraph 2:Linda and I helped each other through the time.__________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ __________________________________________________________________________________ _________________________________【答案】It was exciting to go to school again but it was no game. Sitting in a classroom full of kids was awkward, even if most of them were respectful and encouraging. During the day, I was still a busy married woman having loads of housework to do. In the evening, I was a hardworking student working on my courses. To my surprise, both Linda and I did very well in night school. I went back again the next semester, and my grades steadily improved.Linda and I helped each other through the time. When I was down, Linda encouraged me. “Mom, you can’t quit now!” And when she was down, I encouraged her. I have to sa y it was a time which was really hard on both of us. But neither of us gave up. At last, I got my diploma. To my surprise, almost all of my classmates voted for me to be class speaker, and I got a $3,000 college scholarship. The unfinished business in my dreams was eventually finished.【解析】【分析】本篇书面表达是读后续写。

一、现代文阅读（35分）（一）现代文阅读I（本题共5小题，18分）阅读下面的文字，完成1-5题。
材料一：我向来不相信诗是批评人生的，更不愿说诗是描写人生和自然的。
这些全是立于旁观者的地位，专用冷静的头脑去解剖、比较、判断，他们的地位是外而非内的。
至于诗人的态度正好与之相反。
他固不以描写为长技，但也决不会只是批评。
他决不会只去旁观，而是要同化一切，又为一切所同化的——这即是我所谓“人化”。
总说一句，诗不是离去人生，而是以人生做他的血肉的。
若说诗的目的是去表现人生，仍不免有语病，其实诗是人生表现出来的一部分，并非另有一物，却拿他来表现人生的——故我宁说“诗是人生的表现”。
这不但是诗，可以推之于一切文学。
真诗人的本领是什么？是把自己所曾体验的人生普遍的情感，明明白白、委委婉婉地在笔尖下写出来，去宣扬人世的光、花、爱。
他总竭他的文学天才，使他的作品人人了解，人人感动，即不能遍于人人，也必是大多数识文字的人。
若已竭他的才力，而大多数人终究不能了解，他决不肯视为当然的，必归罪于自己的无力，去想一个忏悔的方法，不如此，不成为第一流的诗人啊！至于或专以解剖刻画为能事，或借艰深的文辞掩饰其浅陋，这些作品无非读了使人受些不正当或过度的刺激，或竟不痛不痒的莫名其妙，虽有文字的仪表，却早已丧失了他的灵魂了。
诗中最宝贵的材料是普遍的情感，异常的心灵现象虽不妨在诗中偶然表现，但其效率决不能如前者广大。
可惜世人好奇心太甚，把真理颠倒过来了。
他们总以为诗人必有了古古怪怪的“幻想”“神思”方成为第一流，却不知道诗人的伟大并不在他心境的陆离光怪，是在他能说出人人所要说而苦于说不出的话。
