Bears, belonging to the family Ursidae, are fascinating creatures that inhabit various ecosystems across the globe. From the majestic polar bear roaming the Arctic to the elusive panda dwelling in the bamboo forests of China,bears have captivated human interest for centuries. In this comprehensive guide, we delve into the world of bears, exploring their biology, behavior, habitat, andconservation efforts.1. Introduction to Bears:Bears are large mammals characterized by their stocky build, shaggy fur, and plantigrade stance. They are omnivorous, meaning they consume both plant matter and meat, although the specific diet varies among species. There are eight extant species of bears, each with its unique characteristics and habitat preferences.2. Species Diversity:The eight bear species include the polar bear, brown bear (which includes grizzly bears), American black bear, Asiatic black bear, sloth bear, spectacled bear, sun bear, and giant panda. Each species has adapted to its environment in remarkable ways, reflecting its evolutionary history and ecological niche.3. Habitat and Distribution:Bears occupy a diverse range of habitats, from the Arctic tundra to dense rainforests and high-altitude mountains. Their distribution spans across North America, South America, Europe, and Asia, with each species having its preferred geographical range. Habitat loss, fragmentation, and human-wildlife conflict pose significant threats to bear populations worldwide.4. Biology and Behavior:Bears exhibit complex social behaviors and communication patterns. While some species, like the polar bear, are solitary, others, such as brown bears, formsocial hierarchies and engage in cooperative behaviors. Bears are known for their intelligence and problem-solving abilities, which they use to forage for food and navigate their environments.5. Reproduction and Life Cycle:Most bear species reproduce sexually, with females typically giving birth to one to four cubs per litter, depending on the species. Cubs are born blind and helpless, relying entirely on their mother for nourishment and protection. The length of gestation and the timing of reproduction vary among species and are influenced by environmental factors.6. Conservation Status:Many bear species face significant conservation challenges due to habitat destruction, poaching, andclimate change. Efforts to conserve bears include habitat preservation, captive breeding programs, and initiatives to mitigate human-bear conflicts. International organizations, governments, and local communities play crucial roles in bear conservation efforts worldwide.7. Human-Bear Conflict:As human populations expand and encroach upon bear habitat, conflicts between humans and bears escalate. Bears may raid crops, livestock, and residential areas in search of food, leading to negative interactions with humans. Effective strategies for mitigating human-bear conflict include education, habitat management, and non-lethal deterrents.8. Conclusion:In conclusion, bears are remarkable animals that play vital roles in their respective ecosystems. Understanding their biology, behavior, and conservation needs isessential for ensuring their survival in the face ofmounting anthropogenic pressures. By adopting sustainable practices and promoting coexistence between humans and bears, we can safeguard these iconic creatures for future generations to admire and appreciate.In summary, bears are fascinating creatures that command our attention and respect. Through education, conservation efforts, and responsible stewardship of the environment, we can ensure the survival of bears and preserve their rightful place in the natural world.。

考点4 阅读理解科学科普类—五年（2020—2024年）高考英语真题专项分类汇编学校：___________姓名：___________班级：___________考号：___________ 一、阅读理解When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately, it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources. Millions of waterfowl(水禽) were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat(栖息地).In 1934, with the passage of the Migratory Bird Hunting Stamp Act (Act), an increasingly concerned nation took firm action to stop the destruction of migratory(迁徙的) waterfowl and the wetlands so vital to their survival. Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp. The very first Federal Duck Stamp was designed by J.N. "Ding" Darling, a political cartoonist from Des Moines, Iowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System—a fact that ensures this land will be protected and available for all generations to come. Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated. 1．What was a cause of the waterfowl population decline in North America?A.Loss of wetlands.B.Popularity of water sports.C.Pollution of rivers.D.Arrival of other wild animals.2．What does the underlined word "decimate" mean in the first paragraph?A.Acquire.B.Export.C.Destroy.D.Distribute.3．What is a direct result of the Act passed in 1934?A.The stamp price has gone down.B.The migratory birds have flown away.C.The hunters have stopped hunting.D.The government has collected money. 4．Which of the following is a suitable title for the text?A.The Federal Duck Stamp StoryB.The National Wildlife Refuge SystemC.The Benefits of Saving WaterfowlD.The History of Migratory Bird HuntingIn the race to document the species on Earth before they go extinct, researchers and citizen scientists have collected billions of records. Today, most records of biodiversity are often in the form of photos, videos, and other digital records. Though they are useful for detecting shifts in the number and variety of species in an area, a new Stanford study has found that this type of record is not perfect."With the rise of technology it is easy for people to make observations of different species with the aid of a mobile application," said Barnabas Daru, who is lead author of the study and assistant professor of biology in the Stanford School of Humanities and Sciences. "These observations now outnumber the primary data that comes from physical specimens(标本), and since we are increasingly using observational data to investigate how species are responding to global change, I wanted to know: Are they usable?"Using a global dataset of 1.9 billion records of plants, insects, birds, and animals, Daru and his team tested how well these data represent actual global biodiversity patterns."We were particularly interested in exploring the aspects of sampling that tend to bias(使有偏差) data, like the greater likelihood of a citizen scientist to take a picture of a flowering plant instead of the grass right next to it," said Daru.Their study revealed that the large number of observation-only records did not lead to better global coverage. Moreover, these data are biased and favor certain regions, time periods, and species. This makes sense because the people who get observational biodiversity data on mobile devices are often citizen scientists recording their encounters with species in areas nearby. These data are also biased toward certain species with attractive or eye-catching features.What can we do with the imperfect datasets of biodiversity?"Quite a lot," Daru explained. "Biodiversity apps can use our study results to inform users of oversampled areas and lead them to places—and even species—that are not well-sampled. To improve the quality of observational data, biodiversity apps can also encourage users to have an expert confirm the identification of their uploaded image."5．What do we know about the records of species collected now?A. They are becoming outdated.B. They are mostly in electronic form.C. They are limited in number.D. They are used for public exhibition.6．What does Daru's study focus on?A. Threatened species.B. Physical specimens.C. Observational data.D. Mobile applications.7．What has led to the biases according to the study?A. Mistakes in data analysis.B. Poor quality of uploaded pictures.C. Improper way of sampling.D. Unreliable data collection devices.8．What is Daru's suggestion for biodiversity apps?A. Review data from certain areas.B. Hire experts to check the records.C. Confirm the identity of the users.D. Give guidance to citizen scientists.Popularization has in some cases changed the original meaning of emotional(情感的) intelligence. Many people now misunderstand emotional intelligence as almost everything desirable in a person's makeup that cannot be measured by an IQ test, such as character, motivation, confidence, mental stability, optimism and "people skills." Research has shown that emotional skills may contribute to some of these qualities, but most of them move far beyond skill-based emotional intelligence.We prefer to describe emotional intelligence as a specific set of skills that can be used for either good or bad purposes. The ability to accurately understand how others are feeling may be used by a doctor to find how best to help her patients, while a cheater might use it to control potential victims. Being emotionally intelligent does not necessarily make one a moral person.Although popular beliefs regarding emotional intelligence run far ahead of what research can reasonably support, the overall effects of the publicity have been more beneficial than harmful. The most positive aspect of this popularization is a new and much needed emphasis(重视) on emotion by employers, educators and others interested in promoting social well-being. The popularization of emotional intelligence has helped both the public and researchers re-evaluate the functionality of emotions and how they serve people adaptively in everyday life.Although the continuing popular appeal of emotional intelligence is desirable, we hope that such attention will excite a greater interest in the scientific and scholarly study of emotion. It is our hope that in coming decades, advances in science will offer new perspectives(视角) from which to study how people manage their lives. Emotional intelligence, with its focus on both head and heart, may serve to point us in the right direction.9．What is a common misunderstanding of emotional intelligence?A.It can be measured by an IQ test.B.It helps to exercise a person's mind.C.It includes a set of emotional skills.D.It refers to a person's positive qualities. 10．Why does the author mention "doctor" and "cheater" in paragraph 2?A.To explain a rule.B.To clarify a concept.C.To present a fact.D.To make a prediction.11．What is the author's attitude to the popularization of emotional intelligence?A.Favorable.B.Intolerant.C.Doubtful.D.Unclear.12．What does the last paragraph mainly talk about concerning emotional intelligence?A.Its appeal to the public.B.Expectations for future studies.C.Its practical application.D.Scientists with new perspectives.As cities balloon with growth, access to nature for people living in urban areas is becoming harder to find. If you’re lucky, there might be a pocket park near where you live, but it’s unusual to find places in a city that are relatively wild.Past research has found health and wellness benefits of nature for humans, but a new study shows that wildness in urban areas is extremely important for human well-being.The research team focused on a large urban park. They surveyed several hundred park-goers, asking them to submit a written summary online of a meaningful interaction they had with nature in the park. The researchers then examined these submissions, coding(编码) experiences into different categories. For example, one participant’s experience of "We sat and listened to the waves at the beach for a while" was assigned the categories “sitting at beach” and “listening to waves.”Across the 320 submissions, a pattern of categories the researchers call a “nature language” began to emerge. After the coding of all submissions, half a dozen categories were noted most often as important to visitors. These include encountering wildlife, walking along the edge of water, and following an established trail.Naming each nature experience creates a usable language, which helps people recognize and take part in the activities that are most satisfying and meaningful to them. For example, the experience of walking along the edge of water might be satisfying for a young professional on a weekend hike in the park. Back downtown during a workday, they can enjoy a more domestic form of this interaction by walking along a fountain on their lunch break."We’re trying to generate a language that helps bring the human-nature interactions backinto our daily lives. And for that to happen, we also need to protect nature so that we can interact with it," said Peter Kahn, a senior author of the study.13．What phenomenon does the author describe at the beginning of the text?A. Pocket parks are now popular.B. Wild nature is hard to find in cities.C. Many cities are overpopulated.D. People enjoy living close to nature.14．Why did the researchers code participant submissions into categories?A. To compare different types of park-goers.B. To explain why the park attracts tourists.C. To analyze the main features of the park.D. To find patterns in the visitors’ summaries.15．What can we learn from the example given in paragraph 5?A. Walking is the best way to gain access to nature.B. Young people are too busy to interact with nature.C. The same nature experience takes different forms.D. The nature language enhances work performance.16．What should be done before we can interact with nature according to Kahn?A. Language study.B. Environmental conservation.C. Public education.D. Intercultural communication.Rainforests are home to a rich variety of medicinal plants, food, birds and animals. Can you believe that a single bush(灌木丛) in the Amazon may have more species of ants than the whole of Britain! About 480 varieties of trees may be found in just one hectare of rainforest. Rainforests are the lungs of the planet-storing vast quantities of carbon dioxide and producing a significant amount of the world's oxygen. Rainforests have their own perfect system for ensuring their own survival; the tall trees make a canopy(树冠层) of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds.Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is the plants' way to prevent the spread of any tree diseases and make life more difficult for leaf-eating insects like caterpillars. To survive in the forest, animals must climb, jump or fly across the gaps. The ground floor of the forest is not all tangled leaves and bushes, like in films, but is actually fairly clear. It is where dead leaves turn into food for the trees and other forest life.They are not called rainforests for nothing! Rainforests can generate 75% of their own rain. At least 80 inches of rain a year is normal-and in some areas there may be as much as 430 inches of rain annually. This is real rain—your umbrella may protect you in a shower, but it won't keep you dry if there is a full rainstorm. In just two hours, streams can rise ten to twenty feet. The humidity(湿气) of large rainforests contributes to the formation of rainclouds that may travel to other countries in need of rain.17．What can we learn about rainforests from the first paragraph?A.They produce oxygen.B.They cover a vast area.C.They are well managed.D.They are rich in wildlife.18．Which of the following contributes most to the survival of rainforests?A.Heavy rainsB.Big trees.C.Small plants.D.Forest animals. 19．Why do the leaves and branches of different trees avoid touching each other?A.For more sunlight.B.For more growing space.C.For self-protection.D.For the detection of insects.20．What can be a suitable title for the text?A.Life-Giving RainforestsB.The Law of the JungleC.Animals in the AmazonD.Weather in RainforestsAccording to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上) participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: theparticipants followed suit but took significantly more candy when the thin actor took 30 pieces.The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the "I'll have what she's having" effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?21．What is the recent study mainly about?A.Food safety.B.Movie viewership.C.Consumer demand.D.Eating behavior.22．What does the underlined word "beanpoles" in Paragraph 1 refer to?A.Big eaters.B.Overweight persons.C.Picky eaters.D.Tall thin persons.23．Why did the researchers hire the actor?A.To see how she would affect the participants.B.To test if the participants could recognize her.C.To find out what she would do in the two tests.D.To study why she could keep her weight down.24．On what basis do we "adjust the influence" according to the last paragraph?A.How hungry we are.B.How slim we want to be.C.How we perceive others.D.How we feel about the food.参考答案1．答案：A解析：理解具体信息。

文章标题：Earthquake Science Week:Understanding and PreparednessEarthquake Science Week is an annual event dedicated to enhancing public awareness and knowledge about earthquakes, their causes, and the measures we can take to mitigatetheir impact. This weeklong campaign is crucial in arming individuals and communities with the necessary information and skills to respond effectively in the event of an earthquake.To begin, it is essential to understand the science behind earthquakes. Earthquakes occur when there is a sudden release of energy in the Earth's crust, often caused by the shifting of tectonic plates. These plates, which make up the Earth's outer shell, are constantly in motion, colliding and rubbing against each other. When the stress builds up to a critical point, it is released suddenly as an earthquake, sending seismic waves that can be felt on the surface.During Earthquake Science Week, we learn about the different types of earthquakes, their magnitudes, and the factors that determine their destructive potential. Forinstance, the Richter scale measures the magnitude of an earthquake, while the Mercalli scale assesses its intensity or the degree of damage it causes. Understanding these scales helps us appreciate the severity of an earthquake and prepare accordingly.Moreover, Earthquake Science Week emphasizes the importance of preparedness. We are taught about the safety measures we can take in our homes and offices, such as securing heavy furniture, storing breakable items in low-risk areas, and creating an emergency plan with our families. It is also essential to know what to do during an earthquake, including protecting our heads and necks, staying away from windows and glass doors, and dropping to the ground if indoors.Furthermore, the weeklong event highlights the role of emergency responders and the need for community collaboration in disaster management. We learn about the emergency services available in our area and how to contact them in case of need. We also discuss the importance of helping neighbors and working together to restore normalcy after an earthquake.Beyond the practical aspects, Earthquake Science Week also encourages a deeper understanding of the Earth'snatural processes.

Life on-line can be a much richer experience when you aren't restricted to just written words and still pictures. Even if you're new to the Net, you've probably heard but multimedia on-line--listening to audio，watching animations and videos, even playing in three-dimensional space.Sound and movement make information come alive.To experience it,you'll need special pieces of software called plug-ins. The term"plug-in quot;refers to a small，add-on piece of software which extends the capabilities of your web browser，like Netscape Navigator or Microsoft Explorer,turning your computer into a radio or TV. When you arrive at a web page which contains a file requiring a plug-in which you don't have,you will usually receive a message asking if you want to get it by downloading it and installing it into your computer. Most of the time, the installation will be automatic.Occasionally, you'll run into a downloaded file which needs to be decompressed orun-zipped before installation. Once installed，,plug-ins run automatically，without you having to do anything.Many multimedia controls still need to be obtained from the developer but are installed automatically.Shock wave is a good example of this. All you need to do is go to the Macromediasite and click on the link to install the ActiveX control. The rest happens automatically.The next time you go to a "Shocked"website,the Shock wave control loads and playsthe movie.Most plug-ins and controls can be downloaded for free on the Internet, although no tall will work with every system. Some of them，for instance，only work withwindows95.当你不再仅仅限于文字和静止图片时，网上生活会丰富多彩得多。

Recently the Japanese company Hitachi has invented a robot that has its own sense of humor and the ability to understand when someone else doesn’t share it.The redandwhite robot is known as EMIEW2.It stands at 80 centimeters—no taller than a small child—and is equipped with a pair of roller skates that allow it to quickly move around.The robot is programmed to recognize key words in a sentence，such as “how many”，in order to understand what sort of question it’s being asked.The little robot is further programmed to understand a wide range of human responses，such as shrugs or nods.It has the ability to carry on a short conversation with a human—without being given a script and it allows the robot to work out whether or not the person it’s talking to understands its joke.For example，the robot is asked how many people work at the Hitachi lab，and it answers，“We have two swans.” When its human conversation partner appears puzzled，the robot says，“You got it？I’m kidding.We have about 800 people working here.”“Maybe EMIEW2’s sense of humor needs a lot of work，” said Hitachi’s Hisashi Ikeda，“its ability to understand human reactions was an important step forward.”“The new technology makes it possible for a robot to understand what a human means，even if they gesture，”he said.EMIEW2 is short for Excellent Mobility and Interactive Existence as a Workmate.Hitachi hopes to have EMIEW2 provide company to people，serving as a housepet or even a receptionist or caregiver.Notes：1．nifty [′nIftI]adj.俏皮的；漂亮的2．Hitachi日立，日本一家全球最大的综合跨国集团3．response [rI′spɒns]n．反应4．shrug [ʃrʌɡ]n．& v．耸肩5．script [skrIpt]n．剧本6．Excellent Mobility and Interactive Existence as a Workmate具有卓越的灵活性和交互性的工作伴侣7．receptionist [rI′sepʃənIst]n．接待员Have a Try：1．How does the robot move around?A．By a pair of roller skates.B．By its two legs.C．By human beings.D．By electricity.2．The robot can do the following things EXCEPT .A．having a talk with humansB．making gesturesC．telling jokesD．recognizing whether you understand its jokes3．We know from the reading that .A．the robot determines if you’ve got the “joke” it has just told by asking you questions B．the robot tells perfect jokesC．the robot can answer whatever questions you askD．the robot will be a perfect house or office helper in the futureTest 2Family MealsTeenagers who turn off the TV and sit down to family meals are less likely to have eating disorders，take drugs，drink or struggle at school.A study has connected eating together with lower rates of bulimia and anorexia.Kids who are used to eating round the table are less likely to take up smoking to lose weight.Besides，they are more likely to have meals on time.Researcher Barbara Fiese said，“In many people’s opinion，teenagers don’t want to be around their parents very much.Besides this，they are too busy with their studies and spend more time with their friends.”The study shows happy families have teenagers who eat with their parents often.These teens have less bad diet or dangerous eating habits.“For most parents，it is difficult to get their families together around the table seven days a week.But if they can have three family meals a week，it will be good for their children’s health，”she added.Professor Fiese has found that teens who eat at least five meals a week with their families are 35 percent less likely to be “disordered eaters”．Even three family meals a week helped，withyoungsters 12 percent less likely to be overweight than those who ate with their families less often.They were also 24 percent more likely to eat healthy foods and have healthy eating habits than those who didn’t share three meals with their families.Teens can also use family meals as a time to get their thoughts across.Professor Fiese said，“Family meals give them a place where they can go regularly to check in with their parents and express themselves freely.”Notes：1．eating disorders饮食失调症2．bulimia [bu′lImIə]n．暴食症3．anorexia [ˌænə′reksIə]n．厌食症Have a Try：1．Which of the following is NOT a reason why children don’t eat with their parents? A．They don’t want to be with their parents too often.B．They spend a lot of time with friends.C．They think their parents are too strict.D．They are too busy with their studies.2．What can we learn from the passage?A．It is hard for family members to sit together for meals often.B．It is good for family members to watch TV while having meals.C．Parents will have meals on time if they eat with their children.D．Teenagers who have meals with their parents are cleverer.3．In the article，the author intends to tell us .A．eating together as a family creates better eating habits later in lifeB．the more often teenagers have meals with their parents，the less likely they behave badly C．eating with parents is importantD．the more often teenagers eat with their families，the healthier they areTest 3I Listen to ColorI come from a place where the sky is always grey，where flowers are always grey，and wheretelevision is still in black and white.I actually come from a world where color doesn’t exist.I was born with achromatopsia.I was born completely colorblind.So I’ve never seen color，and don’t know what it looks like.But since the age of 21，I can hear color thanks to a magic electronic eye called “eyeborg”：a color sensor between my eyes connected to a chip installed at the back of my head that transforms color frequencies into sound frequencies that I hear through my bone.I’ve had the electronic eye permanently attached to my head and I’ve been listening to colors nonstop since 2004.So I find it completely normal now to hear colors all the time.Since I started to hear color，my life has changed dramatically.Art galleries have become concert halls.I can hear a Picasso.And supermarkets have become like night clubs.I love how they sound. My sense of beauty has changed.Someone might look very beautiful but sound terrible，and someone might sound very harmonious but look awful.So I find it reallyexciting to create sound portraits of people.Instead of drawing the shape of someone’s face I write down the different notes I hear when I look at them，and then I send them an mp3 of their face.Each face sounds different.I can even give face concerts now，concerts where I play the audience’s faces.The good thing about doing this is that if the concert doesn’t sound good，it’s their fault.I also found out that things I thought were colorless are not colorless at all.Cities are not grey.Lisbon is yellow turquoise；London is very golden red...and humans are not black and white.Human skins range from light shades of orange to very dark shades of orange.We are all orange.If we extend our senses，we will consequently extend our knowledge.Notes：1．permanently [′pз：mənəntlI]ad v.永久地2．turquoise [′tз：kwɒIz]adj.蓝绿色的；宝石绿的Sentence：If we extend our senses，we will consequently extend our knowledge.延伸感官，获得知识。
初一科普英语小文章范文
初一科普英语小文章范文Science is all around us, even in our daily lives. It's not just about complicated experiments or hard-to-understand theories. It's actually pretty cool and interesting!Let's start with something simple: the rainbow. Have you ever seen one? It's a beautiful sight, with all those colors spread across the sky. But did you know that a rainbow is actually a reflection of sunlight and water droplets? That's right! When the sun shines and the rain falls, the light gets refracted and reflected by the raindrops, creating that colorful arc we call a rainbow.Now, let's talk about something a bit more technical. Have you ever wondered why your phone battery drains so fast? It's because of something called energy consumption. Every time you use your phone, whether it's to text, play games, or take photos, it's using energy. And that energy comes from the battery. So, if you want your battery tolast longer, try using your phone less or turning off someof the features you don't need.And here's a fun fact: did you know that chocolate is actually a kind of fruit? Well, technically speaking, it is! Chocolate comes from the cocoa bean, which grows on a tree. And since trees produce fruits, the cocoa bean isconsidered a fruit too. But don't worry, you can stillenjoy your chocolate without feeling guilty!Lastly, let's talk about something that's really cool: space! Have you ever looked up at the night sky and seenall those twinkling stars?。

科普类英语文章 随着科学技术的飞速发展和全球化进程的不断加快，科普文章在向社会大众普及科学技术知识，提高公众科学素养等方面发挥着举足轻重的作用。下面是店铺带来的科普类英语文章，欢迎阅读! 科普类英语文章 生物与环境平衡的危机 The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earth’s vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time, the opposite effect, in which life actually modifies its surroundings, has been relatively slight. Only in the present century has one species man acquired significant power to alter the nature of his world. During the past quarter century this power has not only become increasingly great but it has changed in character. The most alarming of all man’s assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable. In this now universal contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. Chemicals sprayed on croplands or forests or gardens lie long in soil, entering into living organisms, passing from one to another in a chain of poisoning and death. Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation, sicken cattle, and work unknown harm on those who drink from once pure wells. "Man can hardly even recognize the devils of his own creation," as a scientist has said. It took hundreds of millions of years to produce the life that now inhabits the earth. Given time not in years but in millennia life adjusts, and a balance has been reached. But in the modern world there is no time. The rapidity of change follows the impetuous pace of man rather than the deliberate pace of nature. Radiation is now the unnatural creation of man’s tampering with the atom. The chemicals are the synthetic5 creations of man’s inventive mind, having no counterparts in nature. To adjust to these chemicals would require not merely the years of a man’s life but the life of generations. And even this, were it by some miracle possible, would be futile, for the new chemicals come from our laboratories in an endless stream; almost five hundred annually find their way into actual use in the United States alone. Among them are many that are used in man’s war against nature. Since the mid 1940’s over 200 basic chemicals have been created for use in killing insects, weeds, and other organisms described as "pests." It is not my contention that chemical insecticides must never be used. I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. I contend, furthermore, that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil, water, wildlife, and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life. 地球上生命的历史一直就是一部生物与其环境相互作用的历史。在很大程度上，地球上动植物的形态以及习性都是由外部环境所塑造的。考虑到地球上生命存在的整个时间，相反作用，即生命对其周围环境的实际改变作用，却相对很小。只有在当前这个世纪(指20世纪)才有一个物种--人类，获得了强大的力量，改变了其所生存的世界的自然状态。 在过去的1/4世纪中，这种力量不仅日趋强大，而且其性质也发生了变化。在人类破坏环境的种种行为中，最令人担忧的是人类向大气、土壤、河流以及海洋中排放危险甚至致命物质，而当今这种污染在很大程度上是无法挽救的。在当今这种对环境的普遍污染中，化学制品与辐射狼狈为奸，改变着地球的自然状态，也就是改变着地球上生命的自然状态。喷洒到农田、森林或者花园里的化学物质长期滞留于土壤中，渗入有机体内，并彼此相传，形成了一个中毒与死亡的链条。化学物质还神秘地通过地下水传递，最终以新的形式出现并结合，使植物毒死，牲畜害病，并使饮用一度纯净的井水的人遭受了不明之害。正如一位科学家所言：“人类甚至对自己创造的恶魔都不认识。” 地球历经了许多亿年才创造了栖息其上的生命。经过了一定时间--不是以若干年计而是以若干千年计的时间--生命开始适应环境，并形成了一种与环境的平衡。但是在现代世界中，时间这一因素已经没有了。 环境改变的速度不再顺从大自然从容不迫的节奏，而是顺从人类急切匆匆的步伐。辐射是当今人类通过支配原子而得到的一种非自然的创造物。化学制品则是人类有发明创造力的头脑创造出来的合成物，在自然界本无相应的东西。 为了适应这些化学制品，人类需要付出的时间不会只是一个人一生的时间，而是几代人的时间。而即使这样，就算出现奇迹成为可能，这种适应也是徒劳的，因为新的化学制品从我们的实验室中源源不断地涌出。仅在美国，每年就有大约500种化学制品投入使用，其中许多是用于人类对自然的战争中。从20世纪40年代中期起，人类已经创造了200多种基本化学制品用来消灭昆虫、野草以及其他所谓的“有害生物”。
