Ice cream with a pinch of salt known as “yuki shio(snow salt)” does more than simply keep you cool.Unique beachesYonaha Maehama Beach is the most famous beach in Miyakojima, where white sand stretches for seven kilometers. The ocean is colored in emerald blue, mesmerizing visitors with its beauty. Compact Sunayama Beach, known for its arch-shaped rock, is hidden in a small cove, and can only be accessible by walking through a narrow tunnel of trees.Diverse and colorful fishSnorkeling (浅滩潜水) is a must-try in Miyakojma. Dense coral reefs, schools of tropical fish, sea turtles and plenty of space to free dive to depths of 8 to 15 meters close to the shore are standout features.

Even those without a diving license need not be held back.

It connects Miyakojima and Irabujima, stretching for 3540m, drawing a gentle curve (弧线). The length of the bridge can also be read as “san(3)go(5)no shi(4)ma,” meaning coral island in Japanese.

Moreover, they have clear advantages in terms of teamwork and interaction.Cecilia Qi, general manager of GSK China, said, “Digital transformation is both an opportunity and a challenge for women. This is especially the case in the new era, which requires companies to provide women with more support to help them achieve betterwork-life balance and continue to gain success as they continue forward in their career.

was very busy.My romantic husband,Roy,planned a date like we had never had before.A reservation at an expensive r estaurant was made.A beautifully wrapped present had been sitting on my dresser for a few days before the heart-filled holiday.After a hard day at work,I hurried home,ran into the house and jumped into the shower.When my swee theart arrived,I was dressed in my finest outfit and ready to go.He hugged me,just as the sitter arrived.We were both excited.Unfortunately,the youngest member in our household wasn't so happy."Daddy,you were going to take me to buy Mamma a present,"Becky,my eight-year-old daughter said,as she sadly walked over to the sofa and sat down beside the sitter.Roy looked at his watch and realized that if we were to make our reservations,we had to leave right awa

gift that I have ever received.It was a heart-shaped pillow,made by herself,with words "I Love You" stitched on it,filled with love,which I will cherish forever.My wonderful Valentine gift has a special place in my bedroom today,some thirteen years later.As she w as growing up into a young woman,many times I held that pillow close to my heart.I don't know if a pillo w can hold magic,but this

catch a liar in the act-at least 75% of the time,according to a s mall scientific study recently.If additional tests confirm its ability,the lie-detector camera might one day b e used by airport security to identify terrorists before they get on an airplane,says researcher James Levine of the Mayo Clinic.But it is questioned whether the camera would ever be reliable enough to be used on a large scale,or whe ther it could spot someone who plans to commit a crime.Levine and his colleagues enlisted 20 volunteers to help test the camera,which records the heat patterns that are created when blood rushes to the human fac e.The researchers told eight of them to commit a fake crime.They were told to stab a model,rob it of ﹩2 0,then lie about the "rime".The remaining 12 people in the study knew nothing about the crime.The researchers took all 20 people into an interrogation room(审讯室).They asked them whether they ha d stolen $20 and then recorded their answers with a standard polygraph(测谎仪)test and the new camera.The camera caught six out of eight liars as they were lying-the same lie-detecting ability as the polygraph tes t.The camera also correctly identified 11 of the 12 people who were telling the truth-a slightly better rate th an the polygraph.The study is so small that it can't be used as proof of the camera's ability to catch a thief or a liar,Levine says.Still,he is hopeful that the camera is recording a subtle flushing of the face that may automatically occur when someone lies.That flushing may not be caught by the naked eye,but the camera shows a bright red-orange-yellow zon e that represents blood rushing to the eyes.People who lie are afraid of getting caught.That fear triggers a primitive response to run away.Blood goes to the eyes so that the liar can more efficiently map out an es cape route.Levine claims even if the camera works as well as it did in this study,it could mean a thousand passenger s a day would get pulled aside by security,causing lots of missed flights and irate passengers if it mistakenly labeled,thus it may take time before the camera would be ready for a test at a large airport.(1)What does the lie-detector camera detect during the experiment?A.The changes in the testees' emotions.B.The heat patterns in the testees' faces.C.The blood pressure of the testees.D.The testees' heartbeat.(2)Which is the finding about the lie-detector camera by experiment?A.Its lie-detecting ability is somewhat superior to a standard polygraph.B.It can accurately detect who is telling lies.C.The camera can clearly distinguish an honest person from a liar.D.A standard polygraph can't tell who is telling the truth.(3)What can be inferred from the passage?A.The new lie-detector camera still calls for further testing for airport application.B.The liar can't manage to escape if the blood goes to his eyes.C.We can tell blood rushing from some color indicator from one's face.D.The lie-detector camera is designed for airport security.30.(8分)There is a strange tendency nowadays it has become fashionable to blame all of social evils on sch ool teachers.The fact is that teachers are being loaded down with ridiculously high expectations.Some studies have sh own an association between student performance and teacher "effectiveness",depending on how this elusiv e education quality is measured,but there is also confirming evidence proving the stronger connection betw een student performance and a much more important variable:family income.Yes,I'm talking about povert y.Sorry to be so gauche,but when teachers point out the relationship between income and achievement,t hey're not escaping responsibility,but merely stating an embarrassing truth.According to figures by the College Board,students from families making more than﹩200,000 score mor e than 300 points higher on the SAT,on average,than students from families making less than﹩20,000 a y ear.There is,in fact,a clear relationship all the way along the scale:Each rise in higher family income tran slated into points on the test.Sean Reardon of Stanford University concluded in a recent study that the achi evement gap between high-income and low-income students is actually widening.It is unclear why this migh t be happening.Maybe it is due to increased income inequality.Maybe the relationship between income an d achievement has somehow become stronger,and maybe there is some other reason.Whatever the cause,our society's answer seems to be:Beat up the teachers.We tend to believe that mos t of the teachers in low-performing schools are incompetent-and,by extension,that most of the teachers i n upper-crust schools,where students perform well,are paragons(典范)of virtue.But some of the most de dicated and talented teachers I've ever met were working in "failing" rural schools.And yes,in award-winnin g schools where "all the children are above average",I've met some unimaginatively boring teachers who sh ould never be allowed near a classroom.It is reasonable for teachers to take on responsibilities for their performance,but it is not to hold them ac countable for factors that lie far beyond their control.It is fair to insist that teachers approach their jobs wit h the assumption that every single child,rich or poor,can succeed.It is not fair to expect teachers to corre ct all the imbalances that result from growing inequality in our society.(1)The text mainly .A.discusses the social inequalityB.explains why teachers are treated badlyC.argues that it is wrong to blame teachers for all education problemsD.lists reasons beyond teachers' control for students' poor performance(2)The underlined word "gauche" in para.2 is closest in meaning to.A.seriousB.awkwardC.confidentD.proud(3)According to the text,which one of the following is strongly related with student performance?A.Teacher effectivenessB.Parental involvementC.School rankingD.Family income(4)Which of the following would the author most probably agree with?A.Whether all teachers are competent in one school has nothing to do with its overall student performanc e.B.None of the students from poor family perform well in the school.C.Most of the teachers in low-performing schools are lacking in competence.D.Parents should work hard to earn money to ensure their children's performance in the school.笫二节(共10分)根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项.选项中有两项为多余选项.31.(10分)Culture shock isn't a clinical term or medical condition.It's simply a common way to describe the

His grandson wanted to be just like him and tried to copy him in every way he could.One day the grandson asked, “Grandpa, I try to read the book just like you, but I don’t understand it, and I forget what I understand as soon as I close the book. What good does readi ng the book do?”The grandpa quietly turned from putting coal in the stove and replied, “Take this coal basket down to the river and bring me back a basket of water.”The boy did as he was told, but all the water leaked out before he got back to the house. The grandpa laughed and said, “You’ll have to move a little faster next time,” and sent him back to the river with the basket to try again. This time the boy ran faster, but again the basket was empty before he returned. Out of breath, he told his grandpa that it was impossible to carry water in a basket, so he wentto get a bucket instead. The grandpa said, “I don’t want a bucket of water; I want a basket of water. You’re just not trying hard enough.” The boy again dipped the basket into the river and ran hard, but when he reached his grandpa the basket was empty again. Out of breath, he said, “Grandpa, it’s useless!”“So, you think it is useless?” the grandpa said, “Look at the basket.”The boy looked at the basket and for the first time he realized that the basket was different.

Reading for Total ChangingCThe Chinese word “Shanzhai” means a small mountain village, but now it becomes an accepted name for fakes (假货), after “Shanzhai Cell-phones” produ ced by smallworkshops in southern China became popular in the mainland market over the past two years.Besides “Shanzhai” electronic products, there are “Shanzhai” movies, “Shanzhai” stars and even a “Shanzhai” Spring Festival Gala (联欢晚会), a copy of the 25-year-old traditional show presented by CCTV on Chinese Lunar New Year’s Eve.“Shanzhai” has become a culture of its own, meaning anything that imitates something famous. In Chongqing, “Shanzhai” version “Bird’s Nest” and “Water Cube” woven by farmers with bamboo attract wide attention from tourists. Both are copies of the famous Olympic buildings in Beijing.A literature critic said that taking the “Shanzhai” Gala as an example, when the traditional CCTV program becomes less and less attractive to the audience, the “Shanzhai” version appears timely to attract people. “Although it is often connected with poor techniques and operation, ‘Shanzhai’ culture meets the psychological needs of common people and could be a comfort to their minds,” he said. To the mainstream (主流的) culture, the rise of “Shanzhai” culture is a challenge and a motivation (动力). People believe different kinds of cultures developing together is a perfect situation and it is for the public to choose.9. The Chinese word “Shanzhai” may have started with ______.A. fake cell-phoneB. electronic productsC. Spring Festival GalaD. Olympic buildings10. According to the passage, “Shanzhai” culture refers to ______.A. the action that a person imitates(模仿) famous peopleB. products with poor techniques and qualityC. anything that imitates something famousD. those similar names to famous brands(品牌)11. We can infer that the mainstream culture ______.A. is held back by “Shanzhai” cultureB. is the c hallenge of “Shanzhai” cultureC. will be replaced by “Shanzhai” cultureD. may develop faster because of the challenge of “Shanzhai” culture12. Which of the following might be the best title of the passage?A. “Shanzhai” culture will definite ly(注定地) disappearB. “Shanzhai” culture takes on life of its ownC. “Shanzhai” culture — the mainstream cultureD. “Shanzhai” culture — the mountain village cultureDPeople realize that, although animals may not have the same intelligence as human beings, they are smart enough to learn certain things.Dogs are extremely useful as companions for blind people. When a dog has been properly trained, he will always lead his blind master in the right direction and keep him out of danger. For example, seeing-eye dogs learn never to cross a busy road when cars are coming, even if their master ordered them to do so.Horses are also able to learn many things. Horses that are used for guard or police duty must learn never to be frightened of noises, traffic, and other disturbances. Racing horses are able to run much faster than other horses, but they are also quite high nervous. Therefore, it is necessary for those people who train them to be very patient and understanding.The moving pictures and television can use trained animals too. Some animals, such as monkeys and foxes, are easy to film. All you have to do is make a trail in front of the camera by dragging something that smells good to the animals over the ground. Big animals, such as lions and tigers, can be photographed as they bound happily back to their families and dinner. If a movie actor is nearby, the well-trained animal will pay no attention to him. However, the audience may imagine that the actor escaped a terrible death by the skin of his teeth.13. Dogs who help blind people must learn .A. to obey all ordersB. to obey only safe ordersC. never to cross roadsD. to cross road when ordered to do so14. Race horses are hard to train because they are .A. faster than other horsesB. smaller than other horsesC. clever than other horseD. more nervous than other horses15. What does “make a trail” mean here in the last paragraph?A. place something to attract the animalB. give the animal a certain taskC. order the animal to do thingsD. follow the animal to hunt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,并在答题卡上将该项涂黑。

Action Team in ChưRcăm commune, Krông pa district, Gia Lai province, which is known for having the highest number of malaria cases in Vietnam. In 2020, more than 200 cases were reported across the district.Hiao Khanh has been working in malaria prevention and control since 2019, after he recovered from malaria. “It was a near-death experience,” said Hiao Khanh. “I had a high fever before getting medical support. After that, I was determined to help reduce sickness and deaths from malaria in my community.”People in this community depend heavily on the forest to earn a living. They go into the forest to work, and sleep there, putting them at high risk of contracting (感染) malaria. When it rains, the community’s various forest settlements are nearly cut off as the dirt roads are flooded. Hiao Khanh and his team need to use motorbikes to reach different parts of the community to help protect people from malaria.The team’s main activities are to raise awareness about malaria prevention, provide protective items, and find out people who might have malaria and then transport them to healthcare facilities for testing.With the right treatment, patients can now be cured in a shorter period of time. However, ensuring individuals stay on track with their treatment remains a challenge. Forest workers, for example, often prefer to return to work as soon as their fever breaks. Part of Hiao Khanh’s work is to find and persuade (说服) patients to come back for treatment. Communication is an important aspect of his team’s work. They actively listen to people’s concerns, respond to their questions, and stress the importance of completing the full treatment course. “Just a ‘thank you’ from the people is enough to give me strength to continue this job to reduce malaria in my homeland,” said Hiao Khanh.24. What led Hiao Khanh to take an active role in malaria prevention and control?A. His suffering from malaria.B. A report about malaria cases in Vietnam.C. His visit to a nearby forest.D. The deaths from malaria in his community.25. What can be inferred from paragraph 3?A. It often rains in Hiao Khanh’s hometown.B. The community is accessible only by motorbikes.C. Natural disasters frequently hit Hiao Khanh’s hometown.D Forests are not beneficial to malaria control.26. Which of the following is part of the work of the Community Malaria Action Team?A. Treating patients with malaria.B. Educating people about malaria prevention.C. Relocating villagers to other places.D. Improving hospitals and healthcare facilities.27. What is a challenge in Hiao Khanh’s work?A. Curing patients in a short period of time.B. Persuading the villagers to leave the forests.C Talking patients into finishing the full treatment.D. Responding to patients’questioning of his ability.CAs a young music therapist in Colorado, Shannon de L’Etoile saw that when mothers were encouraged to sing to their babies, they were amazed by the positive responses they received. She quickly realized that music could be a powerful tool for helping mothers learn more about their infants (婴儿). Soon, de L’Etoile began researching the practice, called infant-directed singing. She says it helps babies learn to regulate their feelings, which allows them to later behave well in school, and in the social and professional world.“If a mother can sing in a way that catches the infant’s attention, it can help to promote the development of the infant’s brain,” said de L’Etoile. “Infant-directed singing is a way in which mothers can communicate with their babies that most infants can recognize and respond to. But mothers need to be sensitive to infant cues (提示).”De L’Etoile is working with people at the Linda Ray Intervention Center to create a coaching program that will guide mothers in the practice. She is now in the process of training workers at the center, who will coach mothers for a month in the most beneficial ways to sing to their infants. The process includes watching and recording mothers as they sing to their infants and then showing these mothers how they can be sensitive to their infants’ feelings while singing. Mothers will be able to notice if the infant is benefiting because the baby will look longer at the mother and reach a happy state.As part of the study, after each mother completes the training, de L’Etoile will work with a music engineering program to study recordings of the mother’s voice. The study result can show changes over time in the mother’s ability to change her singing according to the infant’s feelings. Videos of the babies will also be studied to discover their connections with their mothers over time. De L’Etoile has been working closely with center workers to develop the program so that it will meet the needs of different families.28. What does the underlined word “regulate” in paragraph 1 probably mean?A. Manage.B. Produce.C. Hide.D. Observe.29. What can we learn from paragraph 2?A. Building a positive parent-child relationship is hard.B. Not all mothers’singing helps develop the infant’s brain.C. Mothers can benefit from singing to their babies.D. Singing is the best way to comfort babies.30. What is the purpose of de L’Etoile’s coaching program?A. To train babies to respond to their mothers.B. To get babies to reach a happy state.C. To help mothers notice the babies’ feelings.D. To teach mothers to sing to babies effectively.31. How will de L’Etoile carry out her study according to the last paragraph?A. By comparing the effects of family members’ voices on babies.B. By collecting babies’ reactions to videos and voices.C. By observing changes in mothers and infants after training.D. By communicating directly with mothers.DRobots doing chores is nothing new, with Tesla having put forward its cool Optimus robot and DeepMind revealing its latest achievements in robotics. Recently, a robot called Mobile Aloha caught the attention of many at the beginning of 2024, with short videos of it cooking at someone’s home going viral in January.Developed by a team of researchers at Stanford University in the US, the robot can handle everything for a dish, whether it is chopping(切) vegetables or cracking eggs.It is also good at various household tasks like watering plants, petting cats, cleaning the floor and doing laundry. It even knows to shake the pillow after putting on a pillowcase (枕套). An Internet user joked under one video that as long as this thing doesn’t try to kill him while he is asleep, he is in real need of it.However, a following video posted by one of the researchers, Tony Zhao, and showing Mobile Aloha’s failures proved that the idea of having a robot servant may just be wishful thinking. In the video, Mobile Aloha randomly smashed(打碎) glasses and plates, collided(碰撞) with cabinets(橱柜) and even burned a pot.It turns out that Mobile Aloha is not a complete self-learning system that can independently navigate new environments. It relies on demonstrations by human operators in its surroundings, meaning that the robot needs to learn from human behavior before completing each task. Also, according to the team, the robot achieves a 95 percent success rate in wiping red wine stains(污渍), 80 percent in pushing chairs, and a me re 40 percent in frying shrimp(虾). In short, it’s far from perfect.The behavioral problems of AI robots have been bothering scientists for decades. Although AI robots do pretty well in things requiring high-level reasoning like math, they perform worse than a one-year-old child when it comes to simple tasks demanding abilities of perception, reflexes(反射) and mobility, among others.As the team observed, the interaction between the arm and the base of Mobile Aloha would get quite complex if more flexibility is required in a task. Even a slight deviation(偏差) in the base settings might lead to significant drift in the arms’ motions, resulting in failure to complete the task.32. What are paragraphs 2-3 mainly about ?A. Mobile Aloha’s chief functions.B. Mobile Aloha’s original designers.C. Mobile Aloha’s online popularity.D. Mobile Aloha’s possible dangers.33. What does Tony Zhao’s video suggest?A. AI robots are ready for household chores.B. Mobile Aloha needs further improvement.C. It is expensive to have robots do chores.D. Robot servants should work under humans’ watch.34. How can Mobile Aloha best complete a new task?A. By copying how humans do it.B. By performing independently.C. By learning from previous tasks.D. By seeking help from programmers.35. Which is the best title for the passage?A. Mobile Aloha—Helping or Messing up?B. Mobile Aloha—a Helper!C. AI Beats Humans.D. AI—Perfect for Housewives.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

条棱,根据每条棱都出现在相邻的两个面中,每条棱连接两个顶点,得出2,2nF E mV E ==,代入2V F E +-=得11112m n E+=+,再分情况判断即可.【小问1详解】根据柏拉图多面体满足性质:2V F E +-=,正十二面体有12个面,即12F =,则10E V =+,设正十二面体每一个面都是正x 边形,每一个顶点处有y 条棱,因为多边形至少有3条边,而再每个顶点处至少有3条棱,则3,3,N,N x y x y ≥≥∈∈,由于每条棱都出现在相邻的两个面中,每条棱连接两个顶点,则有2,2xF E yV E ==,即122,2x E yV E ==,所以220212yV E V x ==+=,所以610V x =-,所以()220y V -=,即()()35210x y --=,由3,3,N,N x y x y ≥≥∈∈,得350,20x y ->->,当21y -=,即3y =时,5x =,符合题意,当22y -=,即4y =时,103x =(舍去),当25y -=,即7y =时,73x =(舍去),当210y -=,即12y =时,2x =(舍去),综上所述,5x =,3y =,此时30,20E V ==,即正十二面体共有30条棱,20个顶点;【小问2详解】设正方体1111ABCD A B C D -的棱长为a ,则32V a =,几何体GHIJKL,是正八面体,所以3112211232226V a a a a =⨯⨯⨯⨯=,所以1216V V =;【小问3详解】假多面体每一个面都是正n 边形,每一个顶点处有m 条棱,因为多边形至少有3条边,而再每个顶点处至少有3条棱,则3,3,N,N n m n m ≥≥∈∈,由于每条棱都出现在相邻的两个面中,每条棱连接两个顶点,则有2,2nF E mV E ==,代入2V F E +-=可得222E E E m n +-=,即11112m n E +=+,当3,3>>m n 时,11111442m n +≤+=,这与0E >矛盾,所以,m n 中至少有一个等于3,若3n =,则1116m E-=,由于0E >,则36,N m m ≤<∈,因此3,4,5m =,则6,12,30E =,对应4,8,20F =,所以存在正四面体,正八面体,正二十面体;若3m =,则1116n E-=,由于0E >,则36,N n n ≤<∈,因此3,4,5n =,则6,12,30E =,对应4,6,12F =,所以存在正四面体,正六面体,正十二面体综上所述,柏拉图多面体只有5种.【点睛】关键点点睛:假多面体每一个面都是正n 边形,每一个顶点处有m 条棱,根据每条棱都出现在相邻的两个面中,每条棱连接两个顶点,得出2,2nF E mV E ==,代入2V F E +-=得11112m n E +=+,是解决第三问得关键.。

AThe moment I walked out of the "Arrivals" gate at the airport,I saw a big handmade signboard "Welcome Xiyun" behind the waiting line,and I knew I had found a caring host family at the other side of the world-the United States.My host mom had already prepared and decorated my room nicely for me.There was a doll on one side of the room,and a bookcase full of books on the other-they had heard I loved reading.Mom had also placed a keyboard for me,since she knew that I played the piano well.My life in the host family did not go very well at first.Because I am the only child in my family in China,I was not used to having two younger kids-Zoe and Grace-running around me yelling(大喊大叫)all the time.Mom had a serious talk with me about this problem on a Sunday afternoon.She told me: "You can't just come home from school every day,go to your room and do your homework.You need to be a part of this family.You need to play with my kids for at least an hour." This rule was very annoying at first.I did not have much experience playing with children. However,the more time I spent with the kids.the more I grew to love them.We played games and read books together. I even taught them Chinese.Thanks to Mom's rule,I began to feel like I was really part of the family.Meanwhile.Mom inspired me to live a healthier life,She got up early every morning to go running.On weekends.she took the whole family to visit parks or go camping.I did not like sports much when I was back home,but now I love to join all kinds of sports.I am healthier and more confident too.With my American family,I found joy and laughter.I learned to live with energy and optimism(乐观)thanks to the care and responsibility of my loving American parents.By Jiang Xiyun21.The passage is mainly about .A.various difficulties Xiyun met in America .B.how Xiyun learned to get along with younger kids in AmericaC.how much Xiyun's caring host family in America changed herD.the cultural differences Xiyun experienced in America22.What can we infer from the passage?A.Xiyun's life with her American host family went very well from the beginning.B.The host mom cared about Xiyun's overall development.C.The host family's two children didn't like Xiyun at all.D.Xiyun didn't notice what the host family did for her.23.How did the host mom influence Xiyun gradually?A.By words and by force.B.By talking and by force.C.By force and by behavior.D.By words and by actions.BWhat would it be like to live on Mars? Volunteers are spending eight months in an area that looks much like the surface of Mars.They are isolated(孤立)high on top of Mauna Loa,a volcanic mountain on the Big Island of Hawaji, living on a simulated(模仿的)or make-believe,Mars Base.The project called HI-SEAS is in the charge of Kim Binsted.She says this wild environment is as close to Mars as you can find on Earth.Because it is so high,the land is not warm or rich with plants,like the rest of Hawaii."You will see there is really no visible plant life or animal life.And you have got this wonderful volcanic material."Mauna Loa,2,500 meters above sea level,is geologically very similar to Olympus Mons on Mars and almost as tall as that Martian mountain.When measured from its base,deep in the ocean,Mauna Loa is the second largest mountain in our solar system,after the one on Mars.The six member HI-SEAS crew is mostly self-sufficient.Food and supplies are brought to them.But the individuals bringing those supplies cannot communicate with volunteers inside the habitat,or base.Kim Binsted says this experiment looks at how the astronauts get along with each other."We study how well they work together,how we can keep them happy and supported,and not wanting to kill each other over these long durations(期间)."Crew members communicate with the outside world through e-mail and blogs.They also produce video on the YouTube website,like this one from mission commander Martha Lenio."I am really enjoying this opportunity to live here and pretend that I'm on Mars and get tolearn all sorts of new skills." One of them said.Whoever gets there first,the trip will not be easy,says Kim Binsted."It is going to be challenging."24.What do we know about Olympus Mons?A.It is 2,500 meters above sea level.B.It is geologically similar to Mauna,Loa.C.It is the second largest mountain on the earth.D.It is a mountain on the Big Island of Hawaii.25.What is the purpose of the experiment?A.To set up a space station.B.To explore new settlement for human.C.To study how the astronauts treat each other.D.To prove human can live in whatever conditions.26.Which can be the best title for the next?A.Volunteers First Explore MarsB.Volunteers Experience Life in HawaiiC.Volunteers Get Taste of Mars in HawaiiD.Volunteers Study the Environment on MarsCGreen living has become more important than ever and as time goes by,it will only become a more important issue.While it used to roe a matter of making an extra effort to save energy and reduce waste in our homes,this has extended to the professional side of things since.Public buildings,such as schools,hospitals and offices,are under an increasing amount of pressure to make the change and go green,even if it's just a step-by-step process that takes a few years to complete.There are plenty of reasons for offices to go green and these reasons go beyond the concept that it should be done just for the sake of the environment.While the environment is unbelievable important and vital to our survival and quality of life,sustainable(可持续的)office design can also have positive impacts upon employees and people using the building.For example,a report carried out last.September revealed that the way an office is designed can significantly impact on the health of the staff there.It was also found to have an effect on productivity and could be a contributory(起作用的)factor to the amount of sick leave and staff turnaround within the business.It's fascinating to think that people can be so sensitive to theirenvironments but it also makes a lot of sense.Even the choice of colour in your office can negatively or positively affect the people working there.Based on this study,it is clear that companies should be making more efforts to improve on the office design while making sure the environment is sustainable and green.There are various little changes that can be made to lead to something bigger,from making sure the lights are turned off at night to recycling the paper your company gets through on a weekly basis.Once these changes are in place,you can start looking at the bigger picture and begin complete changes to design and construction,like having wood fibre insulation(绝缘)fitted.Along with other sustainable features,insulation can be beneficial in various ways.Not only will an insulated office space be environmentally sound by helping you to keep warm in the winter and cool in the summer,reducing the reliance on the thermostat(恒温器)and central heating and saving money,but it can also be an effective form of sound absorption.The study revealed that noise is a contributory factor to productivity problems,and if you work in a particularly busy area,then noise can become a real issue.The aim is to create an environment that is comfortable and calm enough for people to concentrate and work productively.Soundproof walls are an effective and environmentally friendly solution.27.What is the author's argument in the passage?A.Green living can help to save energy.B.Public building should go green.C.Green living still has a long way to go.D.It is important to lead a green life.28.The author mentioned the report carried out last year for the purpose of .A.showing us how to design an officeB.telling us the side effects of green livingC.improving the productivity of office workers.D.proving the benefits of green office design29.According to the author,what is necessary for companies to do?A.Allow enough sick leave to their employees.B.Paint all the walls of their offices green.C.Make some improvements to their office design.D.Make their staff more productive than before.30.The last paragraph mainly tells us about .A.the benefits of insulation to officesB.how to keep an office's temperature constantC.the advantages of living a green life in the cityD.how to make staff work comfortably and effectively第二节(共5个小题,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。
