AThe extraordinary Eastgate Building in Harare，Zimbabwe's capital city，is said to be the only one in the world to use the same cooling and heating principles as the termite mound (白蚁堆)．Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building，which has no airconditioning and almost no heating.The building—the country's largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size.The Eastgate's owners saved $3.5 million on a $36 million building because an air-conditioning equipment didn't have to be imported.The complex is actually two buildings linked by bridges across a shady，glassroofed atrium (天井) open to the air.Fans suck flesh air in from the atrium，blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents (通风口)．As it rises and warms，it is drawn out via ceiling vents and finally exists through fortyeight brick chimneys.During summer's cool nights，big fans blow air through the building seven times an hour to cool the empty floors.By day，smaller fans blow two changes of air an hour through the building，to circulate the air which has been in contact with the cool floors.For winter days，there are small heaters in the vents.This is all possible only because Harare is 1，600 feet above sea level，has cloudless skies，little dampness and rapid temperature changes—days as warm as 31℃commonly drop to 14℃at night.“You couldn't do this in New York，with its hot summers and cold winters，”Pearce said.The engineering firm of Ove Arup & Partners monitors daily temperatures.It is found that the temperature of the building has generally stayed between 23℃ and 25℃，with the exception of the annual hot period just before the summer rains in October and three days in November，when a doorkeeper accidentally switched off the fans at night.And the air is fresh—far more so than in airconditioned buildings，where up to 30% of the air is recycled.21．Why was Eastgate cheaper to be built than a conventional building?A．It was designed in a smaller size. B．No air conditioners were fixed in.C．Its heating system was less advanced. D．It used rather different building materials.22．What does “it” refer to in Paragraph 3?A．Hollow space. B．Baseboard vent.C．Fresh air from outside. D．Heat in the building.23．Why would a building like Eastgate NOT work efficiently in New York?A．New York has less clear skies as Harare. B．Its dampness affects the circulation of air.C．New York covers a larger area than Harare. D．Its temperature changes seasonally rather than daily.24．The data in the last paragraph suggests Eastgate's temperature control system ．A．works better in hot seasons B．can recycle up to 30% of the airC．functions well for most of the year D．allows a wide range of temperaturesBSiberian tiger is the largest felid(猫科动物)in the world and is knownas the king of the forest.In the 1980s，it was listed as one of the firstclass national protected animals of China.To preserve this valuablespecies，the Siberian Tiger Park was built in 1996 in HeilongjiangProvince.The Park is located far away on the north bank of the Songhua River to the northwest of Harbin，occupying an area of 1，440，000 square meters.It is the largest natural park for wild Siberian tigers in the world at present.There are over 500 purebred(纯种的)Siberian tigers here.What's more，visitors can also see white tigers，lions，leopards，and pumas as well as Bengali tigers.It is a large park divided into ten areas，including the mature tiger area，the young tiger area，the walking area，the platform area for viewing the tigers.The mature tiger area has an area of 360，000 square meters with 30 unruly(任性的)Siberian tigers wandering there.The tigers in this area are all about 7 or 8 years old.And in the young tiger area，there are over 40 young lovely，active tigers about 2 years old.Visitors can see some of them playing and fighting with each other in a pool nearby，and others are kept in the walking area，staying together.For visitors who love to see exciting activities，the Park is also a perfect place.In addition to viewing the tigers walking leisurely in the open air，visitors can buy poultry(家禽)or animals to feed them，including ducks，chickens，and even cows.Park employees will set the living animals free among the tigers，and visitors can see the unique live action of tigers preying upon(捕食) them.In addition，there is a free Popular Science Exhibition Hall in the Park.In the exhibition hall，people can see information on tigers in pictures and samples as well as in words，which helps to complete what we know.25．What's the passage mainly about?A．The valuable species—Siberian tiger. B．The largest felid in the world.C．Popular Science Exhibition Hall in the Park. D．Introduction of the Siberian Tiger Park.26．What can you see in the young tiger area?A．Some mature Siberian tigers were wandering in the park.B．Some Siberian tigers were walking leisurely in the open air.C．Some active tigers were playing and fighting with each other in a pool nearby.D．Some lovely tigers were preying upon some poultry or animals one by one.27．How can we find the tigers fierce and violent?A．By buying the living animals to stay in the park.B．By setting living poultry or animals free among the tigers.C．By taking pictures of the tigers staying together.D．By viewing the tigers on the platform in the park.28．The Exhibition Hall in the Park tells us that some information on tigers ．A．is very simple B．partly appearsC．is entirely shown in detail D．completely looks in vainCFor the Travel section，writers and editors selected special items to profile from a dozen cities.Brussels：ChocolateNearly half the chocolate consumed in the world is eaten in Europe，and Belgium —with average consumption of 14.99 pounds per person a year — certainly covers its fair share.While Brussels，the country's capital，is home to hundreds of chocolate makers，what makes a visit necessary is the rich heritage of traditional chocolate makers.Budapest：Paprika(红辣椒)The job of preparing Hungarian paprika was once considered too dangerous for mothers to do.A woman who touched her children upon returning from work risked burning them，so only the elderly and unmarried were allowed the delicate task of separating the skin from the flesh.But by the early 20th century，sweeter varieties and a machine turned paprika into a common feature of all Hungarian cuisine.Lisbon：Tiles (瓷砖)Is there a bluer country than Portugal？The blue sky and Atlantic Ocean embrace the land.The blue moods of Fado，the dark folk music，form the national soundtrack.And all across Portugal，the typically blue designs of azulejos—ceramic tiles —are spread across churches，castles，palaces，university halls，parks...The result is a beautiful land of Christian saints，Portuguese kings，historical glories，aristocrats(贵族) at leisure，seascapes and so on.Madrid：GuitarsWalking into one of Madrid's storied guitar makers' workshops can feel like stepping into the past.Curly wood shavings，from the palest pine to ebony，fall onto the floor as artisans (工匠) turn some humble wood into works of art.It's painstaking work — all done by hand — with classical guitar models and the methods of making them changing little over the last century.29．What does the job of preparing Hungarian paprika suggest?A．The popularity of Hungarian peppers. B．The difficulty of processing peppers.C．The unique tradition in Budapest. D．The hot level of Hungarian peppers.30．Which city can be a splendid setting for a film?A．Brussels B．Budapest. C．Lisbon. D．Madrid.31．What's the similarity of the four items?A．They're all treasures of a city. B．They all date back several centuries.C．Their production processes are all painstaking. D．They all win popularity in most European countries.DIt's high time someone spoke up for today's college students.They're probably the most hardworking，ambitious people in America and their problems are not properly appreciated.People like the Secretary of Education simply don't know what they're talking about when they knock students.Nor do those who complain about falling academic standards.The vast majority of the nation's 12 million students are struggling to pay for their educations.They are part of the invisible workforce.Many hold down full-time jobs.They're frying hamburgers，photographing weddings，working in construction，and waiting on tables.The fact that they even show up for classes is a wonderful event.The financial situation of most students explains a lot about what is happening in schools.Why are the traditional courses so unpopular？Why are students flocking to accounting and computer science and any professional programs that seem to lead to careers?Answer：Today's working students have been forced into a kind of premature matter-of-fact way of viewing things.Romance is gone．The notion of transforming one's self through study alone has disappeared.Today's students seek freedom from manual labor，and the status conferred by a good job.There are other consequences.Today's students don't have much time or energy to be devoted，and carry out independent research or even do serious homework.That's the secret behind falling academic standards.Students have become consumers.They want grades and certifications.Their professors can't be expected to give a grade of failure to students who are clearly tired from the effort to pay their bills.There's a lot wrong with this situation.It's twisting the definition of education out of shape.Worse，it's creating a generation that is totally unpleasant.The brightest students turn out to be yuppies(雅皮士)．The vast majority are，at least，goodnatured semiliterates.The time has run out for philosophical debates about fixed courses of study.What this country needs is someone to stand up and say that being a full-time student during one's formative years is an honorable calling worthy of support.If families can't or won't give it to their children，then the government should.32．The author's purpose in writing this article is to ．A．awaken the whole society to the problems today's college students faceB．warn Americans that academic standards are fallingC．advise college students to study hard D．provide a suggestion that only full-time students be enrolled 33．Which of the following CANNOT be learned from the passage?A．Many students are often absent from classes.

用自然材料模仿鸟巢建筑的英语作文
用自然材料模仿鸟巢建筑的英语作文Nesting Instincts: Nature's Architectural Blueprint.In the realm of nature, the construction of nests is an intricate and instinctual practice, a testament to the ingenuity and adaptability of birds. These avian abodes, crafted from a medley of natural materials, serve as secure havens for eggs and nestlings, shielding them from the elements and potential predators. By mimicking the construction techniques of birds, humans can not only create captivating artistic representations but also delve into the fascinating world of avian architecture.The Woven Tapestry: Natural Materials in Nest Design.Birds exhibit remarkable selectivity in choosing the materials for their nests, each species showcasing a unique repertoire of preferences. These materials, gathered from the surrounding environment, range from twigs, leaves, and grasses to moss, bark, and even animal fur.Twigs and Branches: Sturdy and readily available,twigs and branches form the structural framework of many nests. Woven together in intricate patterns, they create a stable and secure foundation for the nest's inhabitants.Leaves and Grasses: Softer and more pliable than twigs, leaves and grasses provide insulation and cushioning for eggs and chicks. Their rustling sounds may also serve as a camouflage mechanism, masking the presence of the nest from potential predators.Moss and Bark: The absorbent qualities of moss andbark make them ideal materials for lining nests. They help regulate humidity levels and absorb excess moisture,creating a comfortable microenvironment for the young birds.Animal Fur and Feathers: Soft and insulating, animalfur and feathers add an extra layer of warmth to the nest's interior. They also provide sensory stimulation for chicks, helping them to bond with their siblings and parents.Architectural Styles: Diversity in Nest Design.Just as the materials used in nest construction vary,so too do the architectural styles employed by differentbird species. This diversity reflects the specific needsand habitats of each species, ensuring the survival and success of their offspring.Cups: The most common nest design, cups are simple but effective structures with a concave shape that cradles eggs and chicks. Examples include the nests of robins, blue jays, and sparrows.Cavities: Some birds, such as woodpeckers and chickadees, excavate cavities in trees or other structures. These nests provide excellent protection from the elements and predators.Pendants: Hanging nests, often found in trees or shrubs, are constructed by weaving materials around acentral support. Orioles and weaverbirds are known fortheir elaborate pendant nests.Platforms: Larger birds, such as eagles and hawks, build platform nests that are typically supported by tree branches or cliff ledges. These nests are often lined with soft materials for comfort.Ground Nests: Some bird species, such as grouse and quail, nest on the ground. These nests are often well-hidden among vegetation and may be lined with leaves or grasses.Beyond Aesthetics: The Importance of Mimicking Nest Design.Mimicking bird nest architecture through the use of natural materials not only creates beautiful and unique works of art but also provides insights into the intricate world of avian behavior. By studying the materials and techniques employed by different bird species, we can gain a deeper understanding of their evolutionary adaptations and ecological niches.Furthermore, creating bird nest sculptures can foster a sense of connection with nature and inspire a greater appreciation for the diversity and ingenuity of the avian world. These artworks can serve as reminders of the importance of conservation and the fragility of the natural ecosystems that support these fascinating creatures.Conclusion.The construction of bird nests is a testament to the remarkable adaptability and creativity of the avian world. By mimicking the materials and techniques used by birds, we can not only create captivating works of art but also embark on a journey of discovery into the enchanting realm of nature's architectural wonders. Through the careful observation and thoughtful reproduction of bird nest designs, we not only pay homage to these skilled builders but also cultivate a deeper bond with the natural world around us.。
跟建筑物有关的英语作文初一
跟建筑物有关的英语作文初一Architecture is a field that has captivated the human imagination for centuries. From the grandeur of ancient temples to the sleek, modern skyscrapers that dot the skylines of our cities, the built environment plays a crucial role in shaping our daily lives and experiences. For students in grade 7, exploring the world of architecture can be a fascinating and enriching endeavor, opening their eyes to the intricate interplay of form, function, and cultural expression.One of the most fundamental aspects of architecture is its ability to reflect the values and aspirations of a society. The architectural styles and techniques employed in a particular region or era often serve as a window into the beliefs, traditions, and technological capabilities of the people who created them. For instance, the towering cathedrals of medieval Europe with their soaring spires and intricate Gothic ornamentation were not merely functional structures but embodiments of the religious fervor and artistic sensibilities of the time.Similarly, the grand palaces and monuments of ancient civilizations like Egypt, Greece, and Rome were designed to project power, wealth, and cultural sophistication. The pyramids of Giza, the Parthenon in Athens, and the Colosseum in Rome are all iconic examples of how architecture can be used to convey a sense of grandeur and authority. By studying these architectural marvels, students in grade 7 can gain a deeper understanding of the historical and cultural contexts that shaped their development.Beyond the realm of historical architecture, the contemporary built environment also offers a wealth of insights and inspiration. The rise of modernist and postmodernist design movements in the 20th century has led to the creation of some of the most innovative and visually striking buildings in the world. Structures like the Guggenheim Museum in Bilbao, Spain, designed by Frank Gehry, or the Sydney Opera House in Australia, designed by Jørn Utzon, showcase the incredible possibilities of architectural design when it is combined with cutting-edge engineering and a bold, creative vision.These modern architectural masterpieces not only serve practical functions but also act as cultural landmarks, attracting visitors from around the globe and becoming synonymous with the cities they inhabit. By studying the design principles and underlying philosophies behind these contemporary structures, students in grade 7 can gain a deeper appreciation for the ways in whicharchitecture can shape and reflect the values and aspirations of a society.One of the most fascinating aspects of architecture for students in grade 7 is the way it intersects with other disciplines, such as engineering, urban planning, and environmental science. The design and construction of buildings require a deep understanding of structural integrity, materials science, and the principles of physics. Meanwhile, the placement and organization of buildings within a larger urban context are influenced by factors like transportation, resource allocation, and sustainability.By exploring these interdisciplinary connections, students can develop a more holistic understanding of the built environment and the complex challenges that architects and urban planners face. They may discover, for example, how the incorporation of green building technologies and renewable energy sources can help create more sustainable and eco-friendly structures, or how the layout of a city's streets and public spaces can impact the quality of life for its residents.Furthermore, the study of architecture can also serve as a gateway to broader discussions about the role of design in shaping our experiences and interactions with the world around us. Students in grade 7 may explore how the design of everyday objects, fromfurniture to electronic devices, can influence our perceptions and behaviors. They may also consider the ways in which the built environment can either enhance or hinder accessibility and inclusivity for people with diverse needs and abilities.Through these multifaceted explorations, students in grade 7 can develop a deeper appreciation for the power of architecture to transform and enrich our lives. They may even be inspired to pursue careers in this dynamic field, using their creativity, critical thinking, and problem-solving skills to design structures that not only serve practical functions but also uplift the human spirit and foster a sense of community.In conclusion, the study of architecture for grade 7 students offers a rich and engaging way to explore the intersection of art, science, and culture. By delving into the history, design principles, and contemporary trends of the built environment, these young learners can gain a newfound appreciation for the ways in which architecture shapes our experiences and reflects the values and aspirations of societies past and present. As they navigate the complexities of the modern world, the lessons and insights gleaned from this exploration of architecture can serve as a powerful foundation for their continued growth and development as engaged, informed, and creative citizens.。
