Unit One Text A Man in the Realm of NatureAlexander SpirkinHuman beings live in the realm of nature. They are constantly surrounded by it and interact with it. Man is constantly aware of the influence of nature in the form of the air he breathes, the water he drinks, and the food he eats. We are connected with nature by "blood" ties and we cannot live outside nature.Man is not only a dweller in nature, he also transforms it. Humanity converts nature's wealth into the means of the cultural, historical life of society. Man has subdued and disciplined electricity and compelled it to serve the interests of society. Not only has man transferred various species of plants and animals to different climatic conditions, he has also changed the shape and climate of his environment and transformed plants and animals.As society develops, man tends to become less dependent on nature directly, while indirectly his dependence grows. Our distant ancestors lived in fear of nature's destructive forces. Very often they were unable to obtain the merest daily necessities. However, despite their imperfect tools, they worked together stubbornly, collectively, and were able to attain results. Nature was also changed through interaction with man. Forests were destroyed and the area of farmland increased. Nature with its elemental forces was regarded as something hostile to man. The forest, for example, was something wild and frightening and people tried to force it to retreat. This was all done in the name of civilisation, which meant the places where man had made his home, where the earth was cultivated, where the forest had been cut down.But as time goes on mankind becomes increasingly concerned with the question of where and how to obtain irreplaceable natural resources for the needs of production. Science and man's practical transforming activities have made humanity aware of the enormous geological role played by the industrial transformation of the earth.At present the previous dynamic balance between man and nature and between nature and society as a whole, has shown ominous signs of breaking down. The problem of the so-called replaceable resources of the biosphere has become particularly acute. It is getting more and more difficult to satisfy the needs of human beings and society even for such a substance, for example, as fresh water. The problem of eliminating industrial waste is also becoming increasingly complex.Modern technology is distinguished by an ever increasing abundance of produced and used synthetic goods. Hundreds of thousands of synthetic materials are being made. People increasingly cover their bodies from head to foot in nylon and other synthetic, glittering fabrics that are obviously not good for them. Young people may hardly feel this, and they pay more attention to appearance than to health. But they become more aware of this harmful influence as they grow older.As time goes on the synthetic output of production turns into waste, and then substances that in their original form were not very toxic are transformed in the cycle of natural processes into aggressive agents. Today both natural scientists and philosophers are asking themselves the question: Is man's destruction of the biosphere inevitable?The man-nature relation – the crisis of the ecological situation – is a global problem. Its solution lies in rational and wise organization of both production itself and care for Mother Nature, not just by individuals, enterprises or countries, but by all humanity. One of the ways to deal with the crisis situation in the "man-nature" system is to use such resources as solar energy, the power of winds, the riches of the seas and oceans and other, as yet unknown natural forces of the universe.But to return to our theme, the bitter truth is that those human actions which violate the laws of nature, the harmony of the biosphere, threaten to bring disaster and this disaster may turn out to be universal. How apt then are the words of ancient Oriental wisdom: live closer to nature, my friends, and its eternal laws will protect you!人在自然界| 亚历山大·斯伯金人类生活在大自然的王国里。

基因改造生物带给人类巨大的收益还是危害
转基因技术的利与弊通过基因改造的生物是否会打破自然界的生态平衡，从而导致对环境的危害？面对基因改造生物可以带给人类的巨大收益和可能带来的危害，人类该何去何从？到底转基因生物的利有哪些？弊又有哪些呢？我们将对此问题展开研究。
转基因作物的安全性上。
通过基因方式对生物体进行改良取得了很大的成效。
很多物种在改良后产量有了增加，也增强了防御自然灾害与病虫害的能力。
但值得注意的是，改良后的品种可能会对环境产生一定危害。
他举例说，像“抗虫棉”，这种棉花经过一定的基因转化后，可以使自然界中原来危害棉花的害虫死去，但它也可以使很多非目标的有益昆虫死去。
还有一些农作物被注入一种抗除草剂基因，当农田中施加除草剂时，所有的杂草都会死去，只保留下农作物本身。
但在某种情况下，这种抗除草剂的农作物会和杂草出现杂交，这种杂草就被称为“超级杂草”，消灭起来就非常困难。
大学生命科学院许崇任和国家环保总局南京环境科学研究所的刘标还列举了近年来引起社会广泛关注的转基因作物事件，包括：将巴西豆的基因转入大豆，虽然可以改良大豆营养组成，但可能会引起部分人群发生过敏反应。
转Bt基因玉米可以提高有益昆虫绿草蛉的死亡率和延长发育时间。
用食转基因马铃薯的蚜虫饲喂瓢虫，会影响瓢虫的生殖力与存活。
而蚜虫是温带作物中重要的害虫，瓢虫是其天敌。
据了解，大规模应用转基因生物至今的十几年中，尚未出现因转基因生物引起的危害事件。
人类对转基因生物可能带来的安全性问题的认识也在逐步深入。
专家们认为，人类有能力控制转基因技术可能造成的危害。
相关新闻资料转基因技术的应用对人类来说确实有着巨大的作用，但其安全性也一直受到世人的关注。
2000年7月11日，中国科学院和英国皇家学会、美国、巴西、印度、墨西哥科学院以与第三世界科学院就“转基因植物和世界农业”发表联合声明，指出转基因技术在消除第三世界的饥饿和贫困方面具有不可替代的作用。
同时认为应该加强转基因生物的安全性研究，以保证转基因生物安全与应用的健康发展以与环境和食用的安全性。

如何保护海洋生物多样性的措施英语作文
如何保护海洋生物多样性的措施英语作文全文共3篇示例，供读者参考篇1How to Protect the Ocean's Amazing CreaturesThe ocean is a huge, wonderful place filled with countless types of creatures. From tiny shrimp to gigantic whales, the diversity of life in the sea is mind-blowing! But sadly, many ocean animals are in danger because of human activities like pollution, overfishing, and damaging their homes. If we want to keep enjoying the ocean's incredible biodiversity, we need to take action to protect it. Here are some important steps we can take:Stop Polluting the OceanOne of the biggest threats to ocean critters is all the trash and chemicals we dump into the water. Plastic bags, bottles, straws, and other litter can strangle or choke fish, turtles, birds, and marine mammals when they mistake it for food. Toxic chemicals like oil, gasoline, paints, and cleaning products poison the water and make animals very sick.To protect sea life, we need to properly dispose of our trash instead of littering. Recycle as much as possible and findalternatives to single-use plastics. Don't pour chemicals down drains and be very careful about oil spills or leaks from cars and boats. Even common litter like cigarette butts and food wrappers can pollute the ocean, so always use trash cans!Sustainable FishingHave you ever seen pictures or videos of huge nets full of fish being pulled onto boats? While fishing is a way for people to get food, overfishing happens when too many fish are caught faster than they can reproduce and replenish their populations. This leads to decimated fish stocks.Overfishing doesn't just impact the hunted species - it disrupts entire ocean ecosystems. With fewer prey fish around, predators like tuna, sharks, and marine mammals starve. Removing too many predators allows populations of smaller creatures to explode out of control. The delicate balance gets thrown off.To fish sustainably, we need to enforce limits on how many of each species can be caught and prevent illegal overfishing. Fishing methods that reduce accidental bycatch of non-target species should be prioritized. In some cases, temporary bans may be needed to allow depleted populations to recover.Sustainable aquaculture (fish farming) is another way to meet demand for seafood without destroying wild stocks.Protect Ocean HabitatsAnimals need healthy habitats to survive and thrive. For ocean dwellers, that means everything from warm tropical coral reefs to chilly arctic waters. Their habitats provide food, shelter, breeding grounds, and migration routes. But human activities are destroying and degrading many marine habitats.Coastal development, pollution, irresponsible tourism practices, bottom trawling fishing methods, and acidification from absorbing excess carbon dioxide are severely damaging fragile ecosystems like coral reefs, mangrove forests, kelp forests, and sea grass beds. Climate change is warming and acidifying ocean waters, causing mass bleaching of corals. These diverse hotspots of biodiversity are increasingly threatened.Protecting ocean habitats will require many efforts. We must establish more marine protected areas that restrict harmful activities. Coastal zones should be carefully managed with efforts to preserve natural habitats. Greenhouse gas emissions must be slashed to combat climate change impacts. And everyone can help by respecting wildlife and their environments when we visitbeaches or take ocean activities like boating, snorkeling, or diving.Reduce Plastic WasteWhile all forms of ocean pollution are problematic, plastic waste is one of the most pervasive and devastating. Millions of tons of plastic trash enter the ocean each year from littering, poor waste management, and allowing plastic debris to be swept into waterways and out to sea.Plastic pollution is choking ocean ecosystems on a massive scale. Sea turtles, whales, dolphins, fish, and seabirds consume or get entangled in plastic items like bags, straws, bottles, and abandoned fishing gear. Microplastics are finding their way into every level of the food chain. Chemicals from plastic leak into the water, accumulating in the bodies of marine life.We can all do our part by reducing single-use plastics, recycling properly, participating in beach and community cleanups, and putting pressure on corporations to find sustainable packaging alternatives. Every piece of plastic that stays out of the ocean is a win for the planet's beloved marine creatures.Support Ocean ConservationWhile individual actions are crucial, protecting ocean biodiversity will require worldwide cooperation and support for conservation efforts by organizations, governments, scientists, and ordinary citizens.Conservation initiatives like marine protected areas, habitat restoration projects, pollution cleanups, stringent regulations on commercial activities, and bans on toxic chemicals all play vital roles. Funding for research to study marine ecosystems, monitor wildlife populations, develop sustainable practices, and explore new conservation solutions is also essential.Everyone can contribute through lifestyle changes, consumer choices, grassroots activism, civic engagement, and supporting respected environmental groups. We all must become educated advocates for the ocean and its priceless biodiversity before it's too late.The ocean's vibrant diversity of life is one of nature's most awe-inspiring wonders. From the loud, charismatic dolphins and whales to the silent, alien-like creatures of the deep sea, every species is a precious part of the planet's heritage. If we don't protect them, that amazing biodiversity could be lost forever.It's up to every one of us to cherish the ocean and take action to preserve its incredible riches. Whether it's reducingyour personal pollution, speaking up for conservation, or exploring a career in marine biology, do your part for the sake of the ocean and all its wildly wonderful living wonders! The survival of this vital part of planet Earth is in our hands.篇2How to Protect Ocean LifeHave you ever been to the beach and seen all the different creatures that live in the ocean? The ocean is full of amazing animals like colorful fish, playful dolphins, massive whales, and so many more! But did you know that many ocean animals are in danger? Humans are causing harm to the ocean and its inhabitants in several ways. If we don't take action soon, some species may disappear forever! That would be really sad. Let me tell you about some of the threats to ocean life and what we can do to protect it.One big problem is pollution. Humans produce a lot of trash and waste that ends up in the ocean. Things like plastic bags, bottles, containers, and other debris can harm or even kill ocean creatures. Marine animals sometimes mistake plastic for food and eat it, which makes them sick or causes internal injuries. The plastic can also entangle and trap animals, preventing them frombeing able to swim, eat, or breathe properly. Toxins and chemicals that get dumped or spilled into the ocean are poisonous for marine life too.Overfishing is another serious threat. Fishing is an important industry that provides food for people. But catching too many fish can deplete whole populations and disrupt the balanced ocean ecosystem. Some fishing methods like trawling and longline fishing also accidentally capture non-target species like dolphins, turtles, sharks and seabirds which then get thrown back into the ocean already injured or dead.Climate change driven by human activities like burning fossil fuels is harming the ocean as well. As greenhouse gas levels rise, the ocean absorbs more heat and carbon dioxide, making the water warmer and more acidic. This is very stressful for marine species and endangers ocean habitats like coral reefs. With rising temperatures, sea levels are increasing too, flooding coastal areas that many species depend on for breeding and nursing their young.The good news is that there are lots of things we can do to help protect the amazing biodiversity of the ocean! Simple actions in our daily lives can make a big difference.First, we need to reduce plastic waste and keep trash out of the ocean. Things like plastic straws, utensils, bottles, and bags often get thrown away as litter that can end up in rivers, lakes and seas. Instead of using single-use plastics, we should carry reusable items like metal straws and cloth bags. Any plastic items should be recycled properly. We can also participate in community clean-up events to remove litter from beaches and waterways before it enters the ocean.Next, we should be thoughtful consumers of seafood. Only buy fish caught through sustainable methods that don't deplete species populations or harm other marine life. It's best to look for eco-labels and follow guides on which types of seafood are sustainably sourced. We can also reduce demand by having meat-free meals more often.Additionally, we must find ways to reduce our carbon footprint and cut greenhouse gas emissions that contribute to climate change. Simple actions like walking, biking or taking public transportation instead of driving help. We can also conserve energy at home by turning off lights and electronics when not in use. Planting trees is great too since they absorb and store carbon dioxide.Schools, communities and governments also play an important role in ocean conservation. At school, we can have lessons and organize activities to raise awareness about marine biodiversity and the threats it faces. Community groups can advocate for stronger laws and policies that regulate pollution, overfishing and other harmful activities. Governments should create more marine protected areas that restrict human activities and destructive practices, giving ocean habitats and species a chance to recover and thrive.With creativity and commitment, I'm sure we can keep the ocean and its incredible array of life healthy for generations to come. We all need to do our part, no matter how small the action. The ocean and its diverse species are precious resources that we simply cannot afford to lose. Let's appreciate the oceans and work together to protect them!篇3How to Protect the Amazing Creatures of the OceanThe ocean is an incredible place, filled with fascinating creatures of all shapes and sizes. From the massive blue whale, the largest animal on Earth, to tiny shrimp no bigger than your fingernail, the ocean is teeming with life. In fact, scientistsestimate that the ocean contains over 2 million different species of plants and animals!Unfortunately, many of these amazing ocean creatures are in danger. Humans are causing a lot of damage to the oceans through activities like overfishing, pollution, and climate change. If we don't take action soon, we could lose some incredible ocean animals forever.Luckily, there are things we can do to protect marine life and keep the oceans healthy for all the cool critters that live there. Here are some important steps we should take:Stop OverfishingOne of the biggest threats to ocean creatures is overfishing. This happens when people catch too many fish, leaving not enough behind to breed and replenish their population. It's like if you took every single cookie from the cookie jar – there wouldn't be any left for later!To stop overfishing, we need to put limits on how many fish can be caught. We should also avoid eating endangered fish species so their numbers can recover. My favorite lunch is a tuna sandwich, but maybe I'll start packing a peanut butter and jelly instead to help save the tuna.Reduce Ocean PollutionPollution is another major problem for marine life. Trash and chemicals that get dumped into the ocean can hurt or even kill fish, whales, dolphins, and other sea creatures. Plastic is especially dangerous, as animals can get tangled up in it or mistake it for food.We need to stop treating the ocean like a giant trash can! Instead of littering, we should properly dispose of our garbage and recycle as much as possible. We can also use less plastic by carrying re-usable bags and bottles.Protect Coral ReefsCoral reefs are like underwater cities where thousands of species live and find food and shelter. They're one of the most diverse ecosystems on our planet. But coral reefs all over the world are dying due to pollution, overfishing, and climate change.To save the coral reefs, we need to reduce our carbon footprint by driving less, using less electricity, and finding other ways to cut back on greenhouse gas emissions. We should also avoid disturbing coral reefs while activities like snorkeling or scuba diving.Create Marine Protected AreasMarine protected areas are sections of the ocean where fishing and other human activities are limited or banned. They create safe havens where ocean species can recover and thrive without too many disturbances.Setting up more of these protected zones, especially around important habitats like coral reefs and breeding grounds, will give struggling species a chance to rebuild their populations. It's kind of like a national park, but underwater!Learn More About Ocean LifeOne of the best ways we can protect marine creatures is by learning as much as we can about them. The more we understand how different species live and what they need to survive, the better we can take steps to keep them safe.We're still discovering new ocean species every year! By studying the ocean closely, maybe we can unlock the secrets to saving these amazing animals. Who knows, maybe one of you reading this will grow up to be a famous marine biologist!The oceans are incredible, life-filled places, and it's up to all of us to keep them that way. By ending overfishing, stopping pollution, protecting coral reefs, creating marine reserves, andlearning more about the ocean, we can make sure these wonderful marine creatures will be around for generations to come. Let's work together to be great ocean guardians!。

The modern plague bacterium changes its DNA units slowly, but it does quite often rearrange the order of its genes. Some experts believe gene order can affect pathogenicity [,pæθədʒi'nisiti] . Dr. Krause had available only tiny fragments of DNA, so although he was able to reconstruct all the medieval bacterium’s genes he could not establish the exact order in which the genes were arranged, leaving open the possibility that the bacterium was inherently more pathogenic because its genome was differently organized. All the teeth used in the study will be returned to the skulls from which they were taken, now in a London museum whose archaeologists excavated ['ekskə,veit] the East Smithfield cemetery in the 1980s.

世界卫生组织(WHO)的信息资源
第四章世界卫生组织（WHO）的信息资源世界卫生组织（World Health Organization，WHO）是联合国负责全球卫生事业专门机构，始建于1948年。
WHO的宗旨是力求使各民族达到卫生的最高可能水平。
按WHO组织法对健康的定义，健康不仅是疾病或羸弱的消除，而是体格、精神与社会的完全健康状态。
WHO现有192个成员国，因为其全球性，它所提供的信息资源对发展中国家卫生保健的理论和实践，价值很大。
就涉及专业范围而言，WHO相当于第六、七章美国CDC与FDA二者之和。
第一节至第六节提供全球卫生综合性资源，第七节至二十六节评介全球性重大卫生问题站点的内容，第二十七节至二十八节是两个全球卫生人力资源与医学教育数据库。
第一节WHO主页主页（http://www.who.int/zh/index.html）左栏有：关于世卫组织，说明WHO 的使命；国家，简介各成员国情况；健康主题，世卫组织站点，出版物，研究工具等6个栏目。

我们该如何维持生物多样性英语作文
我们该如何维持生物多样性英语作文全文共6篇示例，供读者参考篇1Title: Our Wonderful World of Plants and AnimalsHello, my friends! Have you ever taken a walk in the park or gone on a hike in the forest? If you have, you've probably seen all sorts of amazing plants and animals living together. From tall trees and colorful wildflowers to squirrels scampering about and birds chirping in the branches, nature is full of wonderful living things!All of these different kinds of plants and animals make up what we call "biodiversity." Biodiversity is the variety of life on Earth. It refers to all the different species of living creatures that inhabit our planet. Just imagine how boring it would be if everywhere you went, you only saw the same few plants and animals over and over again! Thanks to biodiversity, we get to experience the incredible richness and beauty of nature.Why is Biodiversity Important?Biodiversity is really important for many reasons. First of all, every living thing on Earth plays a role in the environment and is connected to other living things in some way. Plants and animals all depend on each other to survive. For example, bees help pollinate flowers, which then produce fruits and seeds that birds and other animals eat. If we lost too many species, it could throw off the whole balance of nature!Biodiversity is also important for humans. Many of the foods we eat, the materials we use for clothing and shelter, and even some medicines all come from plants and animals found in nature. Imagine if we lost those resources! Plus, spending time in nature surrounded by diverse plant and animal life is good for our mental and physical health.Threats to BiodiversitySadly, biodiversity all over the world is under threat from human activities. Habitat loss is one of the biggest dangers to plants and animals. When forests are cut down to make way for farms, cities, and roads, many species lose the homes where they live and the food they eat. Pollution from factories, cars, and trash also harms biodiversity by poisoning the air, water, and soil that living things need to survive.Climate change caused by things like burning too many fossil fuels is another major threat. As the Earth gets warmer, some plants and animals can't adapt quickly enough to the changing temperatures and weather patterns. Other threats include overhunting, overfishing, and the spread of invasive species (plants and animals that are moved from their natural homes to new areas).How Can We Help Protect Biodiversity?The good news is that there are lots of things we can do to protect biodiversity and make sure our planet stays healthy and full of amazing life! Here are some ideas:Reduce, reuse, and recycle as much as possible to cut down on pollution and waste.Save energy and water at home by turning off lights, taking shorter showers, etc.Walk, bike, or take public transportation instead of driving when you can.Plant trees, flowers, and gardens to create habitats for local wildlife.Buy sustainable products made from renewable or recycled materials.Support national parks, nature reserves, and conservation efforts.Learn about endangered species and how to help protect them.Spread awareness about biodiversity by teaching others why it's so important!Every little action we take to be moreenvironmentally-friendly helps protect the incredible variety of life on Earth. We're all part of this planet, so it's up to every one of us to be good caretakers of nature. Let's work together to keep our world full of amazing plants, animals, and vibrant biodiversity for many years to come!篇2Title: Our Colorful World: Why Biodiversity MattersHave you ever wondered why our planet is so vibrant and full of life? From the tallest trees in the rainforest to the tiniest insects buzzing around your backyard, Earth is home to an incredible variety of living beings. This rich tapestry of life is called biodiversity, and it's what makes our world so special and beautiful.Biodiversity is all about the different kinds of plants, animals, and other organisms that live on our planet. It's like a big, colorful puzzle with millions of pieces – each piece representing a unique species. Some pieces are big and bold, like elephants and whales, while others are tiny and intricate, like microscopic bacteria. Together, they create a masterpiece that has been billions of years in the making.But why is biodiversity so important? Well, imagine if you had a puzzle with just a few pieces – it wouldn't be very exciting, would it? The same goes for our planet. Without biodiversity, our world would be a dull and lifeless place. Let me share a few reasons why we should cherish and protect the incredible variety of life on Earth.Nature's Superheroes: Every Species Has a RoleEach plant, animal, and organism plays a vital role in keeping our planet healthy and balanced. It's like a giant team of superheroes, where every member has a special power to contribute.For example, bees are nature's pollinators, helping plants reproduce and grow by carrying pollen from one flower to another. Without bees, we wouldn't have many of the fruits and vegetables we enjoy. Trees, on the other hand, are like the lungsof the planet, absorbing carbon dioxide and releasing oxygen for us to breathe.Even the smallest creatures, like bacteria and fungi, have important jobs. They help break down dead plants and animals, recycling nutrients back into the soil for new life to grow.A Delicate Balance: The Web of LifeAll the different species on Earth are connected in a delicate web of life. When one species disappears or struggles, it can have ripple effects throughout the entire ecosystem.Imagine a forest where all the wolves were gone. Without wolves to hunt deer, the deer population would grow out of control, eating too many plants and trees. This could lead to soil erosion, loss of habitat for other animals, and even changes in the local climate.That's why it's so important to protect every species, no matter how big or small. Each one plays a crucial role in keeping nature's delicate balance.Nature's Medicine CabinetDid you know that many of the medicines we use today come from plants and other natural sources? Scientists areconstantly discovering new cures and treatments hidden in the amazing diversity of life on our planet.For example, the Pacific yew tree provides a compound used to treat certain types of cancer. And did you know that the venom from some snakes and spiders is being studied as a potential treatment for diseases like diabetes and heart conditions?By protecting biodiversity, we're not only preserving the beauty of our world but also safeguarding nature's vast medicine cabinet, which could hold cures for diseases we haven't even discovered yet.A Living Library of KnowledgeEvery species on Earth is a treasure trove of information waiting to be explored and understood. Scientists are constantly learning new things from studying the incredible diversity of life, from how animals navigate using the stars to how plants adapt to extreme environments.This knowledge can help us develop new technologies, design more efficient machines, and even solve global challenges like climate change and food shortages.Imagine if we lost an entire species before we had a chance to learn from it. It would be like burning down a library filled with priceless books – a tragic loss of knowledge and potential.A Tapestry of Wonder and JoyBeyond the practical reasons, biodiversity is simplyawe-inspiring and beautiful. It's a kaleidoscope of color, shape, and sound that fills our world with wonder and joy.Can you imagine a world without the majestic roar of a lion or the mesmerizing dance of a butterfly? What about a world without the vibrant hues of a peacock's feathers or the enchanting melody of a songbird's call?Biodiversity is nature's greatest masterpiece, and we have the privilege of being a part of it. It's a source of inspiration, creativity, and pure happiness that enriches our lives in ways we can't even imagine.Protecting Our Colorful WorldNow that you know how important biodiversity is, you might be wondering what you can do to help protect it. Well, the good news is that even small actions can make a big difference!Here are a few simple things you can do:Learn about the amazing plants and animals in your local area and teach your friends and family what you've learned.Reduce, reuse, and recycle as much as you can to help protect natural habitats.Plant a garden or a tree to provide food and shelter for local wildlife.Be an advocate for biodiversity by writing letters or creating art to raise awareness.Support organizations and projects that work to protect endangered species and their habitats.Remember, every single one of us has a role to play in keeping our planet's colorful tapestry of life vibrant and thriving. By working together, we can ensure that future generations can enjoy the wonder and beauty of our incredible, biodiverse world.So let's celebrate the amazing diversity of life that surrounds us and do our part to protect it. Our planet is a true masterpiece, and it's up to us to be its guardians.篇3How Can We Maintain Biodiversity?You've probably heard about biodiversity before, but what does it really mean? Biodiversity refers to the variety of living things on our planet, including plants, animals, fungi, and microorganisms like bacteria. It's kind of like having a big, colorful garden with all sorts of different flowers, trees, and critters living together!Why is biodiversity so important? Well, let me tell you! Every living thing on Earth plays a role in the environment, and they all depend on each other in some way. It's like a big, complicated web of life. If one species disappears, it can affect many other species that rely on it for food, shelter, or other needs.For example, bees are really important pollinators, which means they help plants reproduce by carrying pollen from one plant to another. Without bees, many plants wouldn't be able to make fruits and seeds, and that would affect the animals that eat those plants. See how everything is connected?Biodiversity is also important for humans. We rely on plants and animals for food, medicines, and other products. Plus, diverse ecosystems like forests, wetlands, and coral reefs help clean our air and water, and provide us with places to enjoy nature and have fun!Unfortunately, human activities like pollution, habitat loss, and climate change are threatening biodiversity all over the world. Many species are going extinct, which means they're disappearing forever. That's really sad, isn't it?But don't worry, there are things we can do to help maintain biodiversity and protect the amazing variety of life on our planet. Here are some ideas:Protect natural habitatsOne of the biggest threats to biodiversity is the loss of habitats, like forests, wetlands, and coral reefs. When these areas are destroyed or damaged, the plants and animals that live there have nowhere else to go.We can help by supporting efforts to create and maintain protected areas, like national parks and wildlife reserves. These are safe havens where plants and animals can live and thrive without being disturbed by human activities.Reduce, reuse, and recyclePollution from things like plastic waste, chemicals, and greenhouse gases is harmful to many species and can damage their habitats. By reducing the amount of waste we produce, reusing items instead of throwing them away, and recyclingmaterials like paper, glass, and metal, we can help keep our air, water, and land clean.Plant native speciesWhen we plant gardens or landscapes, we should try to use native plants – plants that naturally grow in our local area. Native plants provide food and shelter for local wildlife, like birds, butterflies, and small mammals. Plus, they're better adapted to the local climate and soil, so they're easier to grow and maintain.Be a responsible pet ownerIf you have a pet, like a cat or dog, make sure to keep them safe and under control. Pets can sometimes harm or disturb local wildlife, especially birds and small animals. Keep your pets indoors or on a leash, and don't let them roam freely in natural areas.Support sustainable practicesLook for products and services that are environmentally friendly and sustainable. This means they're produced in a way that doesn't harm the environment or deplete natural resources. For example, you can buy sustainably harvested wood products, organic food, or clothing made from recycled materials.Learn and educate othersThe more we understand about biodiversity and its importance, the better we can protect it. Read books, watch documentaries, and visit nature centers or zoos to learn about different species and ecosystems. Then, share what you've learned with your friends and family!Preserving biodiversity is really important for the health of our planet and for future generations. By working together and making small changes in our daily lives, we can all help maintain the amazing variety of life on Earth.Remember, every living thing has a role to play, and we're all part of the same big, beautiful web of life. Let's work together to keep that web strong and vibrant for years to come!篇4Title: Protecting Our Planet's Precious BiodiversityHey there, friends! Have you ever heard of the word "biodiversity"? It's a really important word that describes the amazing variety of living things on our planet Earth. From the tiniest bugs crawling on the ground to the tallest trees reaching for the sky, our world is filled with an incredible mix of plants and animals.Biodiversity is like having a huge box of crayons with every color imaginable. Each plant, animal, and living creature is a different shade, and together, they create a beautiful picture –the picture of life on Earth. Just like how a picture wouldn't be as vibrant and interesting with only a few colors, our planet wouldn't be the same without its rich biodiversity.But here's the thing, my friends – our planet's biodiversity is in trouble. Over the years, many plants and animals have become endangered or even gone extinct because of human activities. That means they've disappeared from the Earth forever, and we'll never get to see them again. Isn't that sad?So, what can we do to protect biodiversity and keep our planet's colorful picture intact? Well, there are lots of things we can do, and every little bit helps!First of all, we need to take care of the places where plants and animals live – their habitats. Cutting down forests, polluting rivers and oceans, and building on natural areas can destroy the homes of many living creatures. We should try to protect these habitats as much as we can, so that plants and animals have safe places to live and grow.Another way to help is by reducing our waste and recycling as much as possible. When we throw away too much trash, it canend up in nature and harm plants and animals. Recycling and using less plastic can make a big difference in keeping our planet clean and healthy.We can also learn about the different plants and animals in our area and teach others how important they are. Maybe you can start a nature club at school or volunteer at a local park or nature center. The more people understand the value of biodiversity, the more they'll want to protect it.And you know what else? We can make choices that are good for the environment, like walking or riding a bike instead of taking the car, and turning off lights and electronics when we're not using them. These small actions can really add up and help reduce our impact on the planet.Imagine if everyone in the world did their part to protect biodiversity. We could keep our planet's beautiful picture vibrant and colorful, with all sorts of fascinating plants and animals for generations to come. Just think of all the amazing creatures we'd get to see and learn about!So, let's all work together to maintain biodiversity, my friends. It's up to us to take care of our planet and ensure that every shade and color of life continues to thrive. After all,biodiversity is what makes our world so special and extraordinary!篇5How Should We Maintain Biodiversity?Hi there! My name is Sam, and I'm a 4th grader. Today, I want to talk to you about something really important –biodiversity! Now, I know that might sound like a big, complicated word, but it's actually pretty simple. Biodiversity just means the variety of living things on Earth, like plants, animals, and all the other cool creatures out there.Why is biodiversity so important, you ask? Well, let me tell you! Imagine a world where there were only a few kinds of plants and animals. It would be so boring, wouldn't it? But more importantly, it would be really bad for our planet. You see, all living things are connected in a big, complex web called an ecosystem. Each plant and animal plays a role in keeping that ecosystem healthy and balanced.For example, bees are super important pollinators, which means they help plants reproduce by carrying pollen from one flower to another. Without bees, we wouldn't have lots of the fruits and vegetables we love to eat! And did you know thatsharks help keep the ocean healthy by eating sick or weak fish? If there were no sharks, the ocean would be out of balance, and that could be bad news for all the other creatures that live there.Unfortunately, human activities like pollution, habitat destruction, and overhunting have caused many plants and animals to become endangered or even extinct. That means they're in danger of disappearing from the Earth forever! Isn't that sad? That's why it's so important for us to take care of biodiversity and protect all the amazing creatures that share our planet.So, what can we do to help maintain biodiversity? Here are a few ideas:Reduce, reuse, and recycle! Cutting down on waste and pollution can help protect the homes of many plants and animals. Simple things like using a reusable water bottle instead of buying plastic ones can make a big difference.Plant some trees or start a garden! Having more plants around can provide food and shelter for all sorts of critters, from birds to butterflies to bugs. And gardening is a fun way to get closer to nature!Learn about endangered species and what you can do to help them. Maybe you can donate to organizations that work to protect them, or spread awareness about their plight.Be a responsible pet owner. If you have a pet, make sure you don't release it into the wild, as that can disrupt the local ecosystem. Also, try to choose pets that aren't threatened or endangered species.Visit national parks, zoos, and nature reserves. Not only is it a lot of fun to see all the amazing plants and animals, but it also supports the important work these places do to protect biodiversity.Speak up! Use your voice to encourage your family, friends, and community to make choices that are good for the environment and all the living things that call it home.I know it might seem like just one person can't make a big difference, but that's not true at all! Every little thing we do to protect biodiversity adds up. And the more people who join in, the bigger the impact we can have.Imagine a world where all the incredible creatures – from the tiny ants to the massive blue whales – could thrive and live peacefully. Wouldn't that be amazing? By working together andmaking some simple changes, we can make that dream a reality. After all, this planet belongs to all of us, and we should do everything we can to take care of it and all its amazing biodiversity.So, what are you waiting for? Let's get out there and start exploring, learning, and protecting the incredible variety of life on Earth! Who's with me?篇6How Can We Maintain Biodiversity?Hey there, friends! Have you ever heard of the word "biodiversity"? It's a really cool word that talks about all the different kinds of plants, animals, and other living things on our planet Earth. Can you imagine how many different species there are? From the tiny ants crawling on the ground to the massive blue whales swimming in the ocean, our world is filled with an amazing variety of life!But did you know that many of these plants and animals are in danger? Their homes, called habitats, are being destroyed, and some species are even going extinct, which means they're disappearing forever. Isn't that sad? We need to do something toprotect biodiversity because every living thing on Earth is important and has a special role to play.So, what can we do to maintain biodiversity? Let me share some ideas with you!Protect Natural HabitatsOne of the biggest threats to biodiversity is the destruction of habitats. When forests are cut down, wetlands are drained, or rivers are polluted, the plants and animals that live there have nowhere else to go. That's why it's so important to protect natural areas like forests, grasslands, and wetlands.Imagine if you came home from school one day and found that your house had been knocked down. You'd be so scared and wouldn't know where to go! That's how animals feel when their homes are destroyed.We can help by supporting organizations that work to protect natural areas and by being careful not to damage these places when we visit them.Stop PollutionPollution is another big problem for biodiversity. When we release harmful chemicals into the air, water, and soil, it can make plants and animals very sick, or even kill them.Think about it this way: if you ate a sandwich that was covered in dirt and chemicals, you'd probably get a really bad tummy ache, right? Well, that's what happens to plants and animals when they're exposed to pollution.We can help by reducing the amount of waste we produce, recycling as much as possible, and using eco-friendly products that don't harm the environment.Plant Native SpeciesOne way to support biodiversity is to plant native species of plants in our gardens and parks. Native plants are those that have grown naturally in an area for a long time, and they provide food and shelter for local wildlife.Imagine if you were a bird looking for a place to build your nest. Wouldn't you prefer a tree that you've lived in for generations, rather than a brand new, strange tree that you've never seen before? That's why native plants are so important for animals.We can help by choosing to plant native flowers, trees, and shrubs in our gardens, and by supporting local organizations that work to restore natural habitats with native plants.Be a Responsible ConsumerDid you know that some of the products we buy can actually harm biodiversity? For example, when we buy products made from unsustainable sources, like tropical hardwoods or animal furs, we're contributing to the destruction of habitats and the endangerment of species.It's like if you kept taking cookies from the cookie jar without letting your parents buy more. Eventually, there would be no cookies left, and that would be very sad!We can help by choosing to buy products that areeco-friendly and sustainably sourced, and by supporting companies that are committed to protecting the environment.Learn and Teach OthersOne of the most important things we can do to maintain biodiversity is to learn as much as we can about it and to share that knowledge with others. The more people understand the importance of biodiversity and the threats it faces, the more likely they are to take action to protect it.Think about it this way: if you had a really cool toy that you loved playing with, wouldn't you want to share it with your friends and teach them how to play with it too? That's how weshould think about biodiversity – it's a precious gift that we need to protect and share with others.We can help by reading books and articles about biodiversity, watching documentaries, and even going on nature walks to learn about the plants and animals in our local area. Then, we can share what we've learned with our friends, family, and classmates, and encourage them to get involved too.Maintaining biodiversity is so important for the health of our planet and for all the amazing plants and animals that call it home. It might seem like a big challenge, but if we all work together and do our part, we can make a big difference.Remember, every little action counts, whether it's planting a native flower in your garden, recycling your bottles and cans, or teaching your friends about the importance of biodiversity. Let's work together to protect the incredible diversity of life on our beautiful planet!。

生物的调节与协调机制
生物的调节与协调机制
生物体内的所有生命活动都受到体内各种机制的调节与协调，
从而保证其正常运转。
下面是生物体内几种典型的调节与协调机制：激素调节
激素是通过内分泌系统分泌到体内的一种信号分子，它可以调
节各种生物过程。
激素能够促进或抑制细胞活动、代谢过程和生物
体的生长发育。
其中一些重要的激素包括甲状腺激素、胰岛素、性
激素等。
神经调节
神经调节是指通过神经系统控制生物的生理和行为过程。
神经
系统中的神经元会释放神经递质，从而与其他神经元，在神经网络
中传递信号。
神经调节对于感觉、运动、认知和情感等方面都起着
关键作用。
免疫调节
免疫调节是指通过免疫系统控制生物对外部刺激的应对反应。
免疫系统能够识别和消灭各种病原体，并且在自身免疫性疾病中起到重要作用。
免疫调节也可以改变细胞的命运和代谢过程。
生态调节
生态调节是指通过生态系统中的相互作用和反馈机制，调节生物体的数量和分布。
在生态调节中，生物和环境之间的相互关系起着重要作用。
例如，存在食物链和食物网，食物链和食物网中的灭绝和出现会影响到其他物种的数量和分布。
生物的调节与协调机制是一个复杂的过程，这些机制之间存在着错综复杂的相互作用，一旦其中一个环节出现问题，就会影响到整个生物体的正常运转。

在肝臟或肌肉中的肝糖轉變為葡萄糖，以增加血糖濃度，使身體能夠應付危急的狀況
3.腦垂腺
詳解：腦垂腺分泌多種激素，影響其他內分泌腺體，因此腦垂腺常被稱為人體內分泌系統的主腺
4.血液
詳解：內分泌系統由多種內分泌腺組成，可分泌激素（又稱荷爾蒙），釋放到血液中，隨著血液運送至作用部位的細胞，以調節生理功能
5.丙，乙
詳解：丙：腦幹；乙：小腦
6.D
詳解：男性的睪丸和女性的卵巢統稱為性腺，除了可以產生精子或卵外，也會分泌多種性激素
7.腦幹
詳解：兩眼瞳孔同時收縮，是因為控制瞳孔反射的中樞位於腦幹，且其所傳出的訊息可同時控制雙眼內肌肉的收縮，使瞳孔縮小
8.雌性激素
詳解：卵巢：分泌雌性激素，可促進雌性生殖器官的成熟，並影響女性第二性徵的表現
9.神經元
詳解：神經元又稱神經細胞，由細胞本體和神經纖維組成，為組成神經系統及傳遞訊息的基本單位
10.荷爾蒙
詳解：內分泌系統由多種內分泌腺組成，可分泌激素（又稱荷爾蒙），釋放到血液中，隨著血液運送至作用部位的細胞，以調節生理功能
11.大腦，腦幹
詳解：大腦分為左右兩個半球。
大腦和小腦之外，腦部的其他部位合稱為腦幹，位於大腦的下方、小腦的前方
12.血漿
詳解：內分泌系統由多種內分泌腺組成，可分泌激素（又稱荷爾蒙），釋放到血液中，隨著血液運送至作用部位的細胞，以調節生理功能
13.刺激
詳解：生物為了求生存，需藉由感覺器官感受環境的刺激，並藉由動器協調身體各部位的活動，以產生適當的反應14.胰島素，血糖
詳解：胰島素分泌不足時，血糖濃度過高，過多的血糖隨著尿液排出，即為糖尿病
15.脊髓
詳解：輕敲膝蓋部位韌帶時，會引發脊髓的反射作用，使小腿自然舉起
16.受器
詳解：動物體接受環境刺激的構造稱為受器，分布於眼、耳、鼻、舌、皮膚等感覺器官內，得以感知環境中的光線、聲音、氣味、溫度、接觸、壓力等刺激
17.C
詳解：大腦、小腦各分為左、右兩個半球，心臟分為左心房、右心房、左心室、右心室
18.腦垂腺詳解：腦垂腺分泌生長素，控制個體生長發育
三、題組：
1.C，D
詳解：(1)丙第一次完成走迷宮所需時間及完全走正確所需次數都最少，可知其最聰明
(2)蚯蚓腦部不發達，故成績最差
2.D，B
詳解：(1)進食後一小時內，因食物的消化和吸收，造成血糖濃度上升
(2)進食後兩小時，因胰島素的分泌增加，使血糖進入細胞內利用，或轉換成肝糖儲存在肌肉、肝臟，所以血糖濃度降低。
