Frozen Planet II' Arriving This Winter onBBCAmerica这部纪录片揭露人类面临的最大危机……In this follow-up to 2011's Frozen Planet, the new six-part series called Frozen Planet II revisits the Arctic and Antarctic. It also gives a view into the secret wildlife dramas that play out in all the world’s coldest areas, such as high mountains and frozen deserts.The series shows the great challenges caused by climate change that many polar animals now face. For example, pups of harp seals in the Arctic Ocean rely on sea ice for the first six weeks of life. However, the sea ice of today melts and breaks up sooner in spring. As a result, groups of seal pups fall off the ice into the ocean before they have learned how to swim. Meanwhile, chinstrap penguin chicks use their fur to stay warm. Due to a warming Antarctica, however, more rainy days have led to them suffering from hypothermia.Despite this, Frozen Planet II tells us that there is still hope. Professor Alun Hubbard is a glaciologist from Norway. He has spent over 30 years studying the movement of ice along Greenland's coastline. Although there has been much more ice melting there over the last 20 years, he believes that all these processes canstill be turned back. "Consume less ... think more sensibly about the journeys we take and the food we eat. Figure out a lifestyle that is sustainable," he warns us. 继2011年的《冰冻星球》之后，共六集的全新纪录片《冰冻星球2》再次造访南北两极。

报道自然灾害的英语作文
报道自然灾害的英语作文英文回答：Natural disasters are significant events in the history of humanity, with far-reaching implications. The world has witnessed several devastating disasters, including earthquakes, tsunamis, hurricanes, floods, wildfires, and volcanic eruptions. These events have caused unfathomable loss of life, property damage, and environmental degradation, leaving permanent scars on communities and ecosystems.One of the most infamous natural disasters in recent history is the 2011 Tohoku earthquake and tsunami in Japan. The earthquake, with a magnitude of 9.0, triggered a massive tsunami that devastated coastal areas, resulting in the loss of over 18,000 lives and widespread destruction of infrastructure. The disaster also had a significant impact on the country's economy and its social fabric.Another devastating disaster occurred in 2005, when Hurricane Katrina made landfall in the United States. The hurricane caused catastrophic flooding in New Orleans and surrounding areas, with over 1,800 fatalities and billions of dollars in damage. The government's slow and inadequate response to the disaster further exacerbated its impact, highlighting the challenges in managing natural disasters effectively.In 2010, a massive earthquake in Haiti claimed the lives of over 220,000 people and displaced millions. The earthquake destroyed much of the country's infrastructure, including hospitals, schools, and government buildings, leaving Haiti extremely vulnerable to further disasters. The international community responded with massive aid efforts, but the recovery process has been slow and challenging.Natural disasters not only cause immediate devastation but can also have long-term consequences. Disasters can disrupt essential services, such as healthcare, education, and transportation, which can hinder communities' abilityto recover and rebuild. Moreover, natural disasters often have severe environmental impacts, such as deforestation, soil erosion, and water pollution. These impacts canfurther exacerbate the challenges faced by affected communities and ecosystems.To mitigate the impact of natural disasters, it is crucial to invest in disaster preparedness and risk reduction measures. This involves strengthening infrastructure, developing early warning systems, and educating communities about disaster risks. Collaboration between governments, international organizations, and local communities is essential to ensure effective disaster management and promote resilience.Furthermore, it is important to address the underlying factors that contribute to disaster vulnerability, such as poverty, inequality, and environmental degradation. By promoting sustainable development and reducing social and environmental vulnerabilities, we can create more resilient communities that are better equipped to withstand and recover from natural disasters.中文回答：自然灾害是人类历史上的重大事件，具有深远的影响。

BBC自然界大事件英文解说词 5 (Flood)
Okavango, the Great Flood奥卡万戈大洪水The power of the sun drives the seasons, transforming our planet. Vast movements of ocean and air currents bring dramatic change throughout the year. And in a few special places, these seasonal changes create some of the greatest wildlife spectacles on Earth. One of the most remarkable transformations occurs here in Southern Africa, in the desert lands of the Kalahari. Large herds of animals trek for months in search of food and water, waiting for an event that will dramatically change their lives. For once a year, life-giving water turns an area of unforgiving desert into a vast, watery paradise known as the Okavango. Where and when the Okavango will flood determines the fate of millions of animals, making this one of nature's truly great events.In the heart of Southern Africa, the desert lands of the Kalahari cover an area of almost 400,000 square miles. It's one of driest places on Earth, yet miraculously, great herds of grazing animals survive here. They lead a nomadic existence, trekking huge distances in search of food and water. It's the start of the dry season. It won't rain for eight months, and so life, already hard, is about to get even harder.Of all the animals here, perhaps the most resourceful are the elephants. Each family is led by an older female, the matriarch,and they all rely on her experience to guide them through the desert. Her years here have taught this matriarch that, one day, hundreds of miles to the west, she will find a lush grassland. But before she will find it,her family will have to survive many months in the desert.The water that could transform their lives has its origins a thousand miles away, in the rain clouds over the highlands of Angola. The rain is so plentiful it has the power to transform a desert.It cascades southwards, not to the sea, but into the heart of the Kalahari, towards a basin shaped like a hand known as the Okavango. Here it will fill the swamp that lies at its entrance. And only if the rains have been plentiful will water flood out onto the arid plains beyond, transforming them into the grassland paradise that the herds so badly need.Out in the desert, the elephants need to find water every three days. Thirsty elephants often race into pools, but the matriarch knows that her family must not rush in. This pool is stagnant, and the elephants have a trick that deals with that. Sediment settles to the bottom, and the cleaner, fresher water lies on the surface. They skim it carefully from the top. Then, as gently as elephants can, they move forward slowly, trying not to disturb the stagnant layers. But precious water like this draws in herds from far and wide. In the exuberance of a greeting all their careful work is undone.When bulls are forced together by the need for water, tempers can flare. At this time of year, food and water can often be far apart. And so, now that the little ones are refreshed, the family has to head off to find food.The distant Okavango plains that they're heading for are still dry, and getting even drier. Trapped catfish struggle in a shrinking pool. And the burning sun is not their only enemy. An opportunity like this attracts eagles from many miles away. Usually, they dive and snatch fish from the surface of the water, but in this drought they won't have to work so hard. These are prized catches. Marabou storks and jackals muscle in on the leftovers. But even with this bounty of fish, it's in an eagle's nature to steal a meal rather than catch its own. And all this squabblinggives the marabou a chance. Got it!Only the return of the flood can save these fish now.All around these pools, the grass on the Okavango plains continues to wither and die. But there's still some nourishment left in the leaves, and millions of tiny mouths make the most of what remains. Termites chop the dead grass and drag it underground to feed their colony. They play a crucial role, helping to return nutrients to these poor soils. But now, taking the last, precious grass, they leave dust and sand in its place.With the grazing animals dispersed far and wide, it's leaner times for predators here. Only a desperate leopard would tackle a porcupine. This youngster is about to meet double trouble. The only place to get a bite is on their undersides. But the porcupines work together to watch each others’ backs. The leopard will have to flip one over. Pin-sharp quills can easily snap off and become embedded in flesh. It's a highly effective defence that can also be turned into attack. It's a harsh lesson, but with luck and a bit of healing time, there'll be no lasting damage.Two hundred miles away, the pulse of life-giving water has now reached the swampland at the entrance to the Okavango. Here, thick beds of papyrus act like a sponge,slowing the water's progress.The swamp can take months to fill,and only then, if there is enough water,can it overflow and rejuvenate the plains on which the herds depend.Far to the east,the matriarch elephants have led their families to desert woodlands.It seems an odd place to come - there's no sign of food and there's little shade for the calves.But elephants can do something unusual.They can eat and digest seemingly lifeless branches.The youngsters need to learn that dry sticks are nutritious,and that there is moisture in the bark.But bark won't feed the youngest calves.They need to drink 15 litres of milk a day,so their mothers desperately need water as well as food. Exhaustion has got the better of one young female.But she won't getthe chance to rest for long.The next waterhole could be 30 miles away, and the whole herd needs to get moving.Back on the Okavango plains, the last remnants of grass are going up in smoke.It's bad news for the few grazers that remain. A few birds collect the escaping insects.But fires don't help those who need to eat grass here and now.The Okavango plains are at their most desolate.Yet, out in the desert, t he elephant herds are heading towards them.The matriarchs guide their families along the maze of trails to the next waterhole. And this time there's no hanging about.It soon turns into a mud bath.But elephants have a use for the mud, too,for mud acts both as a sunscreen and an insect repellent.Buffalo have learned to follow the elephant trails to water.There is a clear pecking order here.Elephants take priority, and zebra are the last in the line. Even when young bulls have drunk their fill,they still torment the buffalo. And they definitely know which end to aim for.By the time the herds face their final trek across open desert, the swamp has filled. The channels which lead out onto the parched plains get their first, welcome trickle of water.Amazingly, when the plains are at their driest, fresh water from a distant land spills into the parched river beds. First it fills the dry channels, leaving the baked plains on either side hard and dry.All along the route it finds empty pools to fill.And now, these pools become magnets for birds,which flock here from the surrounding desert lands.Red-billed quelea can now collect those grass seeds that the termites have missed. For most of the year, the quelea are nomadic, and it's this freedom to follow the water that helps make quelea one of the most numerous birds on Earth.As the water fills the Okavango, animals that have survived in shrinking waterholes begin to move in. Female hippos gather in the best territories. And this male is prepared to fight for one. Only a dominant bull will mate with the females, and the current chieftain isn't prepared to give way.The intimidation begins. When neither backs down, there can be only one outcome. Fights can go on for hours and can be to the death. Forward-pointing tusks can stab right through protective blubber. This savage bite to the head brings the contest to an end.The incumbent has re-established his right to mate with the females, and he wastes no time. This is a prime territory, and he will face many more challenges if he is to continue to hold it.The loser is badly injured. Hippos can die from infected wounds,but this young male is fit and should survive.Ox-peckers are a mixed blessing.They keep his wounds clean, but they also keep them open.Fresh water continues to pump through the Okavango plains, bringing life wherever it flows. But out in the Kalahari, water is now almost impossible to find. A matriarch has led her family many miles, only to find the waterhole empty. This year the drought is gripping hard. Each matriarch encourages her family onward. The calves' lives depend on her. And with pools so scarce now, even when she finds water, they won't be drinking alone.At this time of year, some lion prides base themselves around waterholes, and they're always on the lookout for a meal. But the elephants' desperate need to drink outweighs the risk. The mothers are producing less milk, and the calves are weak. The adults try to shield them from watchful eyes. It's an uneasy stand-off. In daylight, the elephants should have nothing to fear. The lions creep as close as they dare, as they too try to drink. One mistake from an elephant and the lions could attack. Big cats keep tired elephants on their toes.While the desert experiences the peak of the drought, the meandering network of channels in the Okavango is finally brimful.They are ready to overflow.Fish gather, ready to ride the flood as a miracle begins to materialise. And the barrier of desert sand seems to dissolve in the magical water.Under cloudless Kalahari skies, fresh, sweet water at last begins to bathe the parched plains. Millions upon millions of litres surge over the banks. This is what the fish have been waiting for. New life returns.And as the water soaks deep into the sand,it stirs dormant animals into life. Others are more forcibly evicted.It's all fresh food, a banquet ready for the feasting. Water birds follow the advancing front, making the most of the sudden harvest.The plains soon teem with life.But not all are here to feed.Some have come to breed.No one knows where they've come from,but within moments of the flood's arrival,tens of thousands of dragonflies appear at the water's edge. The vivid red male leads his partner in a magical dance,guiding her to lay their eggs in the shallows.The flood spills ever onwards, until it finally reaches the outer fringes of the Okavango.The catfish, miraculously, still cling to life.Within moments, the life-giving power of fresh water revitalises them.And now, on the plains that appeared so lifeless,some of the most beautiful and colourful changes occur.Within days, fields of lilies burst into life.They provide pollen for the early bees, and a hiding place for reed frogs.And it's only now that the most crucial gift of the flood, the grass that the desert herds need so badly, begins to grow.Hippos bulldoze their way towards the sprouting grasslands,their paths opening up new arteries that help keep the water flowing.In just a fewweeks,thousands of square miles of dry desert plains are turned into a watery green grassland. The network of hippo paths benefits all kinds of other animals,from predatory crocodiles to the grazing herds.This fresh grass is what the elephants, and indeed all the grazing animals,have been waiting for.Their pace quickens.For months, they have only known the dry smell of the desert.And now, they can catch the scent of fresh grass in the wind.Red lechwe are the first to take advantage of the young shoots.The lions are no threat here.They're not very fast in water, and their prey seem to know it.Lechwe revel in the safety the flood brings.Soon they will be joined by the herds of elephant and buffalo.And the lions seem to know they're not far away.Baboons don't enjoy getting their feet wet,but the banquet of flowers and juicy snails is just irresistible.But they are at their most vulnerable here from lurking crocodiles,so they keep an ever-watchful eye.Babies just cling on tight and hope the water doesn't get too deep. At their feet, the flooded plains are now a vast fish nursery,teeming with life.Predatory fish follow.But they too will have to be wary. For the Okavango now puts on one of the finest bird shows to be seen anywhere in the world. The rising waters create thousands of tiny islands.Safe from predators, surrounded by fish, these are the perfect place to raise chicks. This is the miracle of the Okavango.Once a year, it provides a magical time of plenty at the height of the dry season, in the middle of a desert. Only now, with the grasslands at their most productive,do the great herds arrive,and they've timed it to perfection.The herds grow larger as elephant families and buffalo converge from all over the desert.But as they all get closer to the flooded grassland,there is one final challenge to face.Lions have chosen this thick cover to lay their ambushes. Their favourite prey is the buffalo.Adult buffalo are powerful and can easily trample lions,so the lionesses seek outweaker calves that fall behind the herd. A nervous buffalo mother spots their approach and the herd stampedes. One lioness takes a gamble, moving in on a well-protected calf. The buffalo close ranks,and suddenly, the lionesses beat a hasty retreat. In the panic, calves are separated from their mothers.Amid the confusion, a lioness darts in and grabs one.Many buffalo will fall to lions here.Lions are opportunists,and even an unguarded elephant calf can be vulnerable.The elephants are nervous.The scent of lion is all around, yet they can't see them. A lioness is following them,trying to separate the young straggler from the herd. One adolescent fights back, confronting its enemy.In a panic, the family stampedes.The straggler is taken.After months of arduous trekking, this elephant family has lost one of its young ones.But most of the elephants, at last, have made it through,and the great flood awaits.Older elephants have been here many times before,but the newest calves have never seen so much refreshment. At last, they get that first drink of sweet, fresh water.Thousands of buffalo and zebra have also made it to the magical Okavango wetlands.Somehow, these remarkable elephants have learned how to find a flood from hundreds of miles away, and to time their arrival just right.If it wasn't for this annual gift of precious grass,the herds couldn't survive the dry season in the surrounding Kalahari.This year the Great Flood has lived up to its name. The lives of these elephants are dominated by this annual rhythm of wet and dry,a seasonal cycle driven by the power of the sun.The Okavango River has no great lake to flow into, nor does it ever reach the sea.Its life-giving waters simply evaporate into the great emptiness of the Kalahari sky.In a few months, some may fall as rain far to the north,and, once again,become part of this miraculous event in the Okavango, that is the Great Flood.。

bbc自然灾害的英语新闻报道
BBC Natural Disaster English News Report
A devastating earthquake struck the coastal region of Japan, causing widespread destruction and claiming numerous lives. The tremors, measuring a magnitude of 7.2, rattled buildings and triggered landslides in several cities, leaving communities in a state of shock and despair.
The quake, which originated deep beneath the ocean floor, struck early in the morning, catching many residents off guard. As buildings swayed violently, panicked individuals rushed out into the streets, seeking safety from falling debris. The immediate aftermath of the earthquake was chaotic, with emergency services struggling to cope with the scale of the disaster.
The damage caused by the earthquake was extensive, with buildings collapsing and infrastructure crumbling. In the hardest-hit areas, entire neighborhoods were reduced to rubble, making it difficult for rescue teams to reach those trapped under the debris. Tragically, the death toll continues to rise,
and the true extent of the damage is yet to be fully assessed.
In addition to the destruction caused by the initial earthquake, the region also faced the threat of tsunamis. As the tremors subsided, authorities issued evacuation orders for coastal areas, fearing that the seismic activity could trigger massive waves. Residents hurriedly made their way to higher ground, seeking refuge from the potential disaster. Fortunately, in this instance, the tsunamis did not materialize, sparing the coastal communities from further devastation.
The Japanese government has declared a state of emergency in the affected regions, mobilizing resources to provide immediate relief and support to the affected population. Temporary shelters have been set up to accommodate those displaced by the disaster, while rescue teams tirelessly work to locate and rescue survivors.
International aid organizations have also joined the efforts, offering assistance in the form of medical supplies, food, and clean water. The global community has come together to support Japan in its time of need, highlighting the importance of
international collaboration in the face of natural disasters.
This recent earthquake serves as a somber reminder of the constant threat posed by natural disasters. Japan, located on the Pacific Ring of Fire, is particularly vulnerable to earthquakes, and the country has implemented stringent building codes and advanced warning systems to mitigate the risks. However, even with these precautions in place, the destructive power of nature can still wreak havoc.
As communities begin the long and arduous task of rebuilding, it is imperative that lessons are learned from this disaster. Enhancing infrastructure resilience, improving early warning systems, and investing in disaster preparedness are crucial steps to minimize the impact of future disasters.
In this time of tragedy, the resilience and determination of the affected communities shine through. With global support and a united front, Japan can rebuild and emerge stronger from this devastation.。
