2023届广东省梅州市高三下学期二模英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解Master Gardener Volunteers WantedWhat is a Master Gardener?A master gardener is a citizen that is interested in gardening and can fulfill the training and volunteer hours necessary.Requirements vary by county and state,and the course is tailored for that specific region.You will receive special education on the soils in your area,the types of native plants，insect and disease issues，basic botany，and other information pertinent(相关的)to your gardening zone.The educational opportunity to learn specifics about where you garden will not only help you be-come a better gardener but is then passed along to the general public in lectures,clinics,and through newsletters.What Qualifications Must You Meet?Anyone can apply to be a Master Gardener——you don’t need to be an expert or have a degree.You do,however,need to:●Have certain experience or know a little about gardening or landscape management.●Be willing to share horticulture(园艺学)information with others.●Be willing to attend a training program and can devote time to volunteering and continuing education.Besides,to become a Master Gardener volunteer,each applicant needs to complete an application,prepare background screening paperwork and schedule an interview with Extension staff.What Does the Training Involve?Training sessions are offered one day a week over a three-month period and are led by expert educators in the region.Approximately60hours of classroom instruction and field study and50hours of volunteer internship(实习)work are required to complete the program and become certified.In order to remain a certified Master Gardener,30hours of volunteer work and10hours of continuing education or advanced training are required each year. 1．What does a Master Gardener do?A．Promote gardening practices abroad.experience of starting a library with the books that are thrown away.Gutierrez says he doesn’t reject technology that allows books to be read digitally.But he prefers to read the printed words on paper.“There is nothing more beautiful than having a book in your pocket,in your bag or inside your car.”4．How old was Gutierrez when he started saving books from the trash?A．In his twenties.B．In his thirties.C．In his forties.D．In his fifties, 5．What does the underlined word“They”in Paragraph3refer to?A．Luxury books.B．Garbage trucks.C．Public libraries.D．Poor areas. 6．What did the book Anna Karenina mean to Gutierrez?A．The beginning of his charity project.B．A window to the world.C．One of his greatest achievements in life.D．Some comfort in difficult times. 7．Which of the following sayings does Gutierrez’s story lead us to believe?A．Actions speak louder than words.B．A good book can shine a light upon the soul.C．One man’s trash is another man’s treasure.D．The palest ink is better than the best memory.Jobs that use both technical and creative thinking are among the fastest-growing and highest-paying ones,according to a new report from Burning Glass Technologies,a job market analytic company in Boston.It studied millions of job postings to better understand the skills companies require. What they discovered was that many want workers with experience in such new abilities as big-data gathering and analytic,or design using digital technology.Burning Glass came up with the term“hybrid jobs”to describe these kinds of positions,which require skills not normally found together.For example,these hybrid jobs might require people with skills in data science and advertising,or engineering and sales.“The jobs of the future don’t involve just one skill,“says Matt Sigelman,chief manager of Burning Glass.The company expects general job growth of about10%between2018and2028,but the hybrid jobs by21%.What’s more,hybrid jobs pay more than positions that call for a traditional set of skills.For example,a marketing manager mastering a database program gets paid41%more than a traditional one,with an average yearly salary of$100,000.Moreover,anengineer who improves her sales skills and becomes a consulting engineer fora software company can more than double her pay from$180,000to$400,000.While data shows that workers who fail to update their skills will be able to find fewer jobs,people in hybrid jobs are less likely to become out of date,with only12%possibility of being re-placed by machine,compared with42%for general jobs,says Burning Glass.Hybrid jobs are mostly not beginner roles,so they mainly go to workers with years of experience and,most importantly,more training after leaving college.That means workers,bosses and educators will have to think about how to better prepare people for these roles.8．Why did the company research into job advertisements?A．To understand the growth of best paid workers.B．To compare workers’experience with new abilities.C．To find out companies’requirements about skills.D．To tell the possible changes in future job market.9．Which of the following jobs can be hybrid?A．Data engineer.B．Machine operator.C．Marketing manager.D．Medical consultant.10．How much is a traditional marketing manager possibly paid every year?A．$180,000.B．$71,000.C．$41,000.D．$10,000. 11．Which of the following is the best title for this passage?A．Future Jobs Requiring“Hybrid”Skills.B．How to Get Trained for Jobs.C．Tips on Finding Fastest-Growing Jobs.D．The Jobs with Highest Pay.Art and science may seem like opposite things.One means the creative flow of ideas, and the other means cold,hard data—some people believe.In fact,the two have much in common.Now,a study finds art can help students remember better what they learned in science class.Mariale Hardiman,an education specialist at Johns Hopkins University,noticed that students who used art in the classroom listened more carefully.They might ask more questions.They might volunteer more ideas.What's more,students seemed to remember more of what they had been taught when their science lessons had involved（涉及）art.To prove that,Hardiman teamed up with some researchers and six local schools.In the experiment,the researchers worked with teachers in16fifth-grade classrooms.They provided traditional science lessons and art-focused ones.In a traditional science class, for example,students might read aloud from a book.In the art-focused one,they might sing the information instead.The team randomly assigned（随机分配）each of the350students to either a traditional science classroom or an art-focused one.Students then learned science using that way for the whole unit—about three weeks.When they changed to a new topic,they also changed to the other type of class.This way,each student had both an art-focused class and a traditional one. Every unit was taught in both ways,to different groups of students.This enabled the researchers to see how students did in both types of classes.The team found that students who started off in traditional classes performed better after they moved into an art-focused class.But those who started in an art-focused class did well even when they went back to a traditional science class.These students appeared to use some of the art techniques（技巧）after going back to a traditional class.Classroom teachers reported that many students continued to sing the songs that they learned after finishing the unit."The more we hear something,the more we retain it,"Hardiman says."It suggests that the arts may help students apply creative ways of learning on their own."12．Why did Mariale Hardiman do the study?A．To prove the importance of art at school.B．To know how to encourage students to ask questions.C．To find a way to help her students learn better.D．To see if art might improve science learning.13．What were the students required to do in the experiment?A．Learn three units in total.B．Choose what they'd like to learn.C．Learn two topics for three weeks.D．Take two types of classes.14．What does the underlined word“retain”in the last paragraph mean?A．Remember.B．Express.C．Improve.D．Finish.15．What is the text mainly about?A．Art helps students develop creativity.B．Art-focused classes interest students a lotF．Also,treat your team members respectfully as equals.G．Have a good sense of judgement on important aspects.二、完形填空29．A．accept B．expect C．hear D．notice 30．A．daughter B．patient C．speaker D．friend 31．A．health B．family C．silence D．love 32．A．lesson B．secret C．treatment D．wisdom 33．A．arms B．eyes C．mouths D．faces 34．A．observe B．smell C．review D．suggest 35．A．cutting B．pulling C．brushing D．losing三、用单词的适当形式完成短文四、告知信/通知46．假定你是李华，你的外国朋友Peter给你发邮件说最近经过多次尝试终于学会了做中国传统美食——饺子，开心不已。

AFree Community SwapContact:Catherine Crawford, (718)809-1603Jon Klar, (646)530-0381New Yorkers looking to reduce, reuse, and save money this year are invited to participate in Stop ‘N’ Swap, a free community event organized by local nonprofit GrowNYC.The average NYC household throws away about 2,000 pounds of waste a year. By reusing through events like Stop ’N’ Swap, NYC residents can take part in saving over 40 million pounds of material from landfill every year. Take a break from shopping, support a cleaner future, and join the ever -growing reuse community!WHAT: Free Stop ‘N’ Swap Community Reuse EventWHEN: February 19th, 12pm-3pmWHERE: Bronx Works Classic Community Center—286 East 156th Street, Bronx, NY 10451 The public is invited to bring clean and reusable items. No one is required to bring something to take something—you can simply show up with a bag and see what’s free for the taking. Books, toys, clothing, and electronics are just some of the offerings. Furniture and other large items are not accepted at the swap. Anything leftover at the end of the day is donated or recycled.Stop ‘N’ Swaps have developed a regular following among environmentally conscious New Yorkers. After almost two years without swaps, GrowNYC has set a goal of hosting one swap in each of the city’s 59 communitydistricts each year, providing opportunities to make NYC truly livable—a place where every person can enjoy a healthier life.21．What should you do to get more information from Catherine?A．Call (646)530-0381.B．Call (718)809-1603.C．.D．Visit 286 East 156th Street, Bronx.22．What items are unacceptable at the Stop ‘N’ Swap?A．Dry-as-dust books.B．Old-fashioned clothes.C．Out-of-date electronics.D．Second-hand furniture.23．What is the aim of GrowNYC’s Stop ‘N’ Swaps?A．To make NYC a better place to live.B．To enrich New Yorkers’ community life.C．To reduce the cost of dealing with waste in NYC.D．To encourage districts to compete in sustainability.BAt first look, the playground at the Children’s Guild-Transformation Academy in Baltimore, Maryland, looks like any other. It has swings, slides, and places for children to climb and crawl. But the playground is not just a place for fun. It is also a place where students can learn, grow and gain independence. Everything—from the kind of surface it sits on, to the color of its sitting areas, to the placement of the surrounding fence—is specifically designed for kids with autism(自闭症).Mark Rapaport is the managing director of autism services at the Transformation Academy. He said the school accepts students aged 5 to 21 with autism spectrum disorder (ASD) and are lower functioning.Rapaport said the goal of Transformation Academy is to make the students as independent as possible in an effort to help them prepare for adult life. The school aims to provide help with developing communication and social skills, as well as practical abilities like cleaning or cooking.The playground designed by Maryland company rks@Play, using structures manufactured by Landscape Structures, Inc., took a month to develop, said Dan Hack. He works for rks@Play and helped lead the playground’s design. Hack said he and others spent weeks getting to know the students and understanding their needs before any building was started. The design process involved physical therapists, occupational therapists, and other specialists. The huge $500,000 project was funded with support from the state of Maryland and the nonprofit Orokawa Foundation.Parts of the playground that seem small are very important for children with autism and other disabilities. The surrounding fence extends into a wooded area to make it seem more open. And the ground under the play areas is made of soft, but solid materials to support students using wheelchairsor crutches. The benches on the outside of the playground look simple from far away, but are “one of our most inclusive sensory” elements, Hack said. They have many different colors that bring about feelings of calm and curiosity. They are also made with smooth material that can be felt and moved. The academy’s Rapaport said if a child starts to feel uneasy, they can sit down and feel the bench, which can help them relax.24．Why is the playground in Baltimore designed with special materials?A．To make it superior to other playgrounds.B．To better serve children with autism.C．To improve the quality of the playground.D．To make it easier for kids to climb and crawl.25．What can we learn from the playground project?A．It took a month to complete the project.B．The design process is simple and easy.C．The result of the project is uncertain.D．It’s a money-consuming project.26．What is the last paragraph mainly about?A．The scale and the structure of the playground.B．Ways for kids to free from the stress and relax themselves.C．The underlying logic and reasonable factors of the playground.D．The advantages of the playground for autism and disabled kids.27．Which best describes the playground in Baltimore?A．Advanced.B．Environmental-friendly.C．Functional.D．Convenient.CNew findings suggest that when it comes to learning, the snake may be quite a bit like humans. David Holtzman, a scientist at the University of Rochester, has found that snakes have a much greater capacity for learning than earlier studies had indicated.Holtzman’s study challenged 24 snakes to escape from a black plastic container the size of a child’s pool. Cards mounted on the container’s walls and tape on its floor provided the snakes with visual and touchable signals to find their goal: holes in the container’s bottom that offer a dark, comfortable spot to hide.Simply falling into a hole isn’t the only proof that the snakes are learning something, though. “Speed to find that goal is one of the measures which shows they’re learning,” Holtzman says. “On average, they take over 700 seconds to find the correct hole on the first day of training, and then go down to about 400 seconds by the fourth day of training. Some are actually very fast and find it in less than 30 seconds.”Studies dating back to the 1950s interpreted snakes’ awkwardness with mazes(迷宫) as a poorreflection on their intelligence. “Early attempts to study snake intelligence were problematic because the studies used mazes as testing arenas(场地)——as though snakes might be expected to run through mazes in the same way mice run through mazes,” says Peter Kareiva, a professor of zoology. “Snakes do not encounter anything like mazes in nature, and they do not learn how to run mazes in laboratory conditions.”Holtzman also found a few age-based differences in the signals the snakes use. Young snakes appear to be more adaptable and resourceful, using a variety of clues to find their way to the exit. But their elders seem to rely much more heavily on visual clues. “Actually, one of the amazing findings from our studies is that snakes do use vision in locating places,” says Holtzman. “They don’t just rely on the chemical clues picked up by sticking their tongues out, as many snake biologists assume.”28．What is the function of the cards and tape?A．To direct the snakes to the exits.B．To protect the snakes from bright lights.C．To cover the holes at the container’s bottom.D．To make the container a comfortable spot to stay.29．What do the data in paragraph 3 show about the snakes according to Holtzman?A．They are skillful escapers.B．They are good learners.C．They communicate with each other.D．They adapt to environments quickly.30．What was the problem with early attempts to study snake intelligence?A．They chose the wrong testing arenas.B．They failed to do tests in laboratory conditions.C．They referred to studies dating back to the 1950s.D．They compared snakes with a different kind of animal.31．What astonishes Holtzman about snakes?A．They rely on sight to find their way.B．They leave chemical clues everywhere.C．The young beat their elders in many ways.D．Their tongues are unable to recognize chemical clues.DResearch led by ecologist Bart Hoekstra of the University of Amsterdam shows that birds are affected by the mass use of fireworks on New Year’s Eve up to a distance of 10km (6 miles) away.With data from weather radars and bird counts an international team of researchers revealed how many birds take off immediately after the start of the fireworks, at what distance from fireworksthis occurs and which species groups mainly react.“Birds take off as a result of an acute flight response due to sudden noise and light. We already knew that many water birds react strongly, but now we also see the effect on other birds throughout the Netherlands,” says ecologist Bart Hoekstra of the University of Amsterdam. In the scientific journal Frontier s in Ecology and the Environment, he researchers therefore argue for large fireworks-free zones.Last year, other researchers at IBED discovered that geese are so affected by fireworks that they spend an average of 10% longer looking for food than normal during at least the next 11 days. They apparently need that time to restore their energy to their former condition, after fleeing from the fireworks.Because 62% of all birds in the Netherlands live within a radius of 2.5 km of inhabited areas, the consequences of fireworks are high for all birds throughout the country. “Flying requires a lot of energy, so ideally birds should be disturbed as little as possible during the cold winter months. Measures to ensure this are especially important in open areas such as grasslands, where many larger birds spend the winter. The effects of fireworks on birds are less pronounced near forests and semi-open habitats. In addition, smaller birds such as tits and finches live there, which are less likely to fly away from disturbance.”The authors argue for fireworks-free zones in areas where large birds live. Hoekstra: “These buffer zones could be smaller in areas where light and sound travel less far, such as near forests. Furthermore, fireworks should mainly be lit at central locations in built-up areas, as far away from birds as possible. It would be best for birds if we moved towards light shows without sound, such as drone shows or decorative fireworks without very loud bangs.”32．What can we learn about the research?A．It’s the first one about fireworks’ effects on birds.B．It’s conducted by collecting data from weather radars.C．It shows the extent of the fireworks’ influence on birds.D．It keeps track of birds throughout Netherlands and beyond.33．Why did geese spend more time looking for food?A．To find a place without fireworks.B．To store more food in case.C．To find a new source of energy.D．To make up for the lost energy.34．What does the underlined word “pronounced” in Para.4mean?A．Predictable.B．Noticeable.C．Admirable.D．Avoidable.35．What can be the best title for the passage?A．Fireworks in the world B．Fireworks-free zonesThese problems will drive you mad.in New York.

Maya excitedly points out Doobie’s achievement, proudly claiming his master y of fair sharing. Mama K’s eyes shine with delight as she comments the children for their fairness and praises Doobie for his exceptional problem-solving skills.With Mama K’s encouragement, Maya takes charge, expertly cutting along Doobie’s lines to make three equal slices. Each piece falls into place, their sizes perfectly matched. In a playful display of satisfaction, the children put the slices upon one another, witnessing the unity of their equal proportions. The sight brings smiles of joy to their faces. Amidst the children’s laughter, Doobie’s dad pulls up to pick up the children, and Doobie runs off to meet him. He can’t wait to tell his dad how the badge on the truck has helped him to solve a very tricky problem!。

蟋蟀葫芦①水上勉②三年前的冬天老舍先生曾光临舍下。

日中文化交流协会办事处打电话来说，正在访日的老舍先生想到我家来拜访，问我方便不方便。

③我说，请原谅，我对中国的情况一无所知，老舍先生我也不大熟悉，他的地位究竟相当于日本的哪一位作家呢？那个人告诉我，老舍先生在中国已是文坛泰斗了，地位相当于日本的志贺直哉④。

我那攥着听筒的手颤抖起来。

我家很少有贵客临门，顿时紧张起来。

三天后，老舍先生偕同一位高个子、长脸的中年作家，带着一位女翻译到舍下来了。

我乍一看到老舍先生，吃了一惊。

因为他给我的印象是那么质朴，像是个农村出身的人。

也许是旅途劳累的关系，他的脸色不大好。

他在门口脱下淡褐色夹大衣，里面穿的西服不怎么讲究。

略旧的深蓝色裤子不够笔挺，虽结着黑领带，衬衫的领口却随随便便，我总觉得先生的外貌有点儿像我那位在若狭去世的叔叔。

我松了口气，紧张情绪顿时消失，就把先生迎入客厅。

老舍先生在沙发上坐下来，胳膊肘放在扶手上，弓着背，定睛看着我。

大概那位女翻译已经向他介绍过我的情况，他眼睛里流露出和蔼可亲的神色，为突然造访而向我表示歉意。

说实在的，和老舍先生会面，我想向他请教一下蟋蟀葫芦的事。

先生默默地定睛看着我。

我毕恭毕敬地问道：“老舍先生，我看到过一个据说是从中国的旧货铺买来的葫芦。

似乎是养蟋蟀用的，让它们相斗来解闷。

中国是不是从前就有这样的习俗呢？”“有过的。

”老舍先生通过翻译回答道，他的表情好像一瞬间略为严肃了。

“那么，今天……民间还有这个习俗吗？”“不，那是过去的事。

您见到的罐子，恐怕也有年头了吧？”“老舍先生，我生在日本的若狭这个地方，小时候养蜘蛛玩过。

蜘蛛天生好斗，打得可欢啦，看着挺有趣儿……蟋蟀也像蜘蛛那样好斗吗？”“好斗。

中国的诸侯在近臣中设专人饲养蟋蟀，并且以斗蟋蟀取乐。
