Exploring the unknown has always been a fascinating and thrilling experience for mankind. From the early explorers who set sail to discover new lands to the modern-day adventurers who journey into the depths of the ocean or outer space, the spirit of exploration has always been a driving force in human history.One of the most famous explorers in history is Christopher Columbus, who is credited with discovering the New World in 1492. His voyage across the Atlantic Ocean opened up a new era of exploration and colonization, and his discovery had a profound impact on the course of world history. Columbus' courage and determination to sail into the unknown, despite the many dangers and uncertainties he faced, is a testament to the human spirit of exploration.In modern times, the spirit of exploration continues todrive people to push the boundaries of what is known and discover new frontiers. From the depths of the ocean to the heights of the mountains, from the vastness of outer space to the mysteries of the human mind, there are countless areas that remain unexplored and waiting to be discovered.One of the most exciting frontiers for exploration today is outer space. With advances in technology and space exploration, scientists and astronauts are constantly pushing the boundaries of what is possible in space exploration. From landing on the moon to sending rovers to Mars, the exploration of space has captured the imagination of people around the world.Another area of exploration that has captured the public's imagination is the deep sea. With advances in deep-sea exploration technology, scientists are discovering new species and ecosystems that were previously unknown to us. The depths of the ocean hold many secrets, and the exploration of this vast and mysterious world is an ongoing adventure.In addition to physical exploration, there is also the exploration of the human mind and spirit. Through art, literature, and philosophy, humans have sought to explore the depths of their own consciousness and the meaning of existence. The exploration of the human spirit is a never-ending journey that has inspired countless works of art and literature throughout history.The spirit of exploration is a fundamental part of what it means to be human. It is the driving force behind our curiosity and our desire to push the boundaries of what is known. Whether it is exploring new lands, venturing into the unknown reaches of space, or delving into the depths of the human mind, the spirit of exploration is what drives us to seek out new experiences and expand our horizons.In conclusion, the spirit of exploration has always been a driving force in human history. From the early explorers who set sail to discover new lands to the modern-day adventurers who journey into the depths of the ocean or outer space, the desire to explore the unknown is a fundamental part of what it means to be human. Whether itis the exploration of new lands, the mysteries of the ocean, the vastness of outer space, or the depths of the human mind, the spirit of exploration is what drives us to seek out new experiences and expand our horizons.。

高中英语真题:EXPLORATIONSDATE=6-20-01TITLE=EXPLORATIONS #1957 - LongitudeBYLINE=Oliver ChanlerVOICE ONE:This is Steve Ember.VOICE TWO:And this is Bob Doughty with the VOA Special English progra m EXPLORATIONS. Today, we tell about how people learned an important piece of information necessary for safely sailing on the oceans. It is called longitude.(((THEME)))VOICE ONE:On a foggy October night in Seventeen-Oh-Seven, four English (1) navy ships hit rocks in the Atlantic Oc ean and sank. Two-thousand men (2) drowned. The ships had been sailing in the thick fog for twelve days. There was no sure way to know whe re they were. The commander of the ships had been worried t hat they could hit rocks if they were not careful. He asked his (3) navigators for their opinion on their location in the ocean. The navigators did not really know. They told the commande r they thought they were west of a small island near the coast of northwestern. They were wrong. Instead, they sailed onto rocks near a sm all group of islands southwest of England\'s Atlantic coast. Th e navigators\' lack of knowledge led to the loss of four ships a nd two-thousand lives.VOICE TWO:When people began sailing out of sight of land, sailors did not know how to tell where they were on the open sea. Land trav elers can look at a mountain, a river, or an object that shows t hem where they are in relation to where they came from. On t he ocean, however, there is no sign to tell a sailor where he is . The most important device for knowing directions on the oce an is a (4) compass. A compass is a (5) device containing a metal object that points toward the (6) magnetic north pole. T his shows navigators the direction of north, and therefore also south, east, and west. But sailors need more information to s ail safely on the open sea.VOICE ONE:Most maps of the world show lines that are not on the Earth\'s surface. One line is the equator. It is an (7) imaginary line aro und the widest part of the Earth. There are similar lines both n orth and south of the (8) equator. These circles become smaller and smaller toward the north pole and the south pole. These lines, or circles, are (9) parallel - meaning that they are equally distant from each other at any point around the world. These lines show what is called (10) latitude.A navigator can know the latitude of his ship by observing the location of stars, where the sun rises in the morning and sets i n the evening, and what time of year it is. With this informatio n he knows where his ship is in relation to the north or south p ole and the equator.VOICE TWO:Still, there is one more important piece of information necessa ry for safely sailing the oceans. For many centuries, scientists , (11) astronomers and inventors searched for a way to tell lon gitude. The lines of (12) longitude go the other way from latitu de lines. They stretch from the north pole to the south pole, a nd back again in great circles of the same size. All of the lines of longitude meet at the top and bottom of the world.In her book, Longitude, writer Dava Sobel tells the story about longitude and how the problem of knowing it was solved. (( ))VOICE ONE:For centuries, the great scientists of the world struggled to de velop a way to learn longitude. To learn longitude at any place requires knowledge about time. A navigator needs to know what time it is on his ship and also the time at another place of known longitude - at the very same moment.The Earth takes twenty-four hours to complete one full turn or (13) revolution of three-hundred-sixty degrees. One hour marks one twenty-fourth of a turn, or fifteen degrees. So each hour\'s time differ ence between the ship and the starting point marks a ship\'s p rogress of fifteen degrees of longitude to the east or west. Th ose fifteen degrees of longitude mark a distance traveled.At the equator, where the Earth is widest, fifteen degrees (14) stretches about one-thousand-six-hundred kilometers. North or south of that line, however, the d istance value of each degree (15) decreases. One degree of l ongitude equals four minutes of time all around the world. But in measuring distance, one degree (16) shrinks from about on e-hundred-nine kilometers at the Equator to nothing at the north and sout h poles.VOICE TWO:For many centuries, navigators hoped they could find longitud e by observing the movement of stars at night. During the day , the sun provided information about the time on a ship, and it s direction. However, it did not provide necessary information about the time somewhere else. In the Sixteenth century, oneastronomer suggested that navigators could observe the moo n as it passed in front of different known stars to tell longitude. But, there was not enough information about the stars to use this method (17) effectively. Astronomers could not tell exactly where the moon would be from one night or day to the next. Yet it seemed to those seeking to solve the longitude problem that the only solution was in the moon and stars.(( ))VOICE ONE:During the Seventeenth Century, English astronomers began a major effort to map the stars and their relationship to the mo on as it passed across the sky. Royal Astronomer John Flams teed worked at this task for forty years. The next Royal Astron omer, Edmund Halley, spent another forty years gathering inf ormation about the moon\'s (18) orbit.After many years of gathering the necessary information, it be came possible to learn longitude by observing the stars and th e moon. In Seventeen-Sixty- Six, Royal Astronomer Nevil Maskelyne published the ( 19) Nautical Almanac and Astronomical (20) Ephemeris.It contained all the necessary information about the moon and stars that sailors would need to help them learn their longitud e.This new method was not simple. A navigator had to use complex observing (21) instruments to note the position of the mo on and stars. Then he had to seek the correct information in t he Nautical Almanac about the moon and stars at that time of night or day. The final step in the process was to take the mat hematical information from the book, link it to the current infor mation and solve the resulting problem. This took an average of four hours to do. VOICE TWO:While scientists were studying the stars and moon to solve th e longitude problem, a man named John Harrison was workin g on another project. He was trying to build a clock that would help sailors learn longitude. His task also was difficult and co mplex. Mister Harrison had to develop a clock that was not aff ected by the movement of a ship on the ocean or changes in t emperature or (22) atmospheric pressure.He began developing his clock in Seventeen-Thirty. It took five years to complete. The complex device wei ghed thirty-four kilograms. Several years later, Mister Harrison built a sec ond clock. It was smaller, but weighed more than the first. Mis ter Harrison was not satisfied and began work on another devi ce.Twenty years, later he completed a device that was smaller th an the first two, and weighed less. But, still Mister Harrison wa s not satisfied.Two years later, in Seventeen-Fifty-Seven, he produced a small clock that he could hold in his ha nd. The clock could tell the correct time in two places, meetin g the requirements for learning longitude on the sea.VOICE ONE:For many years after Mister Harrison\'s work was completed, t he idea of using a clock to learn longitude was rejected. Howe ver, that opinion changed when (23) manufacturers learned h ow to make better and less costly (24) versions of Mister Harri son\'s clocks. The clocks became known as (25) chronometer s. By Eighteen- Fifteen, five-thousand chronometers were in use on ships sailing the world \'s oceans. The complex documents and mathematical work w ere no longer necessary. Almost any sailor could tell what his longitude was by simply looking at a clock. The world had cha nged.VOICE TWO:John Harrison\'s clocks can be seen today at the Old Royal (2 6) Observatory in (27) , . The first three are still operating, sho wing the correct time. To look at them is to see the simple sol ution to a problem that worried people for many centuries. To day, the solution to the problem is so common that it is difficul t to understand that there was a problem at all.

Your expert guide drives you through the entrance to Chobe National Park in the deep lines in his gray skin. He seems to look right at you, then moves on to continue his search for more food. Welcome to Africa and the excitementsafaris where you sleep in a tent. The campsite moves with you as you travel through the park.Private hotel companies operate some areas of parks such as Kruger. These hotels can be very costly. But many people think it is worth the cost to enjoy fine food and service. After all, it is not every day you can look out of your bedroom window and see a monkey or elephant standing outside.(MUSIC)VOICE TWO:There are several general rules to follow when traveling on safari. For example, most people wear light-colored clothing such as light brown or tan. This is because lighter colors take in less of the strong heat of the sun than dark colors do. Darker color clothes are also more likely to attract mosquitoes. It is also important to wear a hat and sunscreen lotion to protect your skin from being burned by the very hot African sun. Binoculars are also very helpful for seeing animals that are far away.VOICE ONE:When you are out in nature it is important to speak softly so as not to frighten the animals away. Also, never try to feed or go near one of the animals. And, if you are in a boat, keep your arms and legs out of the water. You might want to touch the water to cool off. But you never know if a hungry crocodile or other creature is nearby. By following these guidelines you can enjoy a safari that is both safe and exciting.VOICE TWO:Tanzania is another country with many parks and game reserves. People who like chimpanzees can visit Gombe Stream National Park on the western border of the country. This is an area of thick forests, ancient trees, and beautiful lakes. Animal expert Jane Goodall made the chimpanzee populations in this area famous. She spent many years studying the behavior of these endangered animals.A guide can take you deep into the forest. As you sit waiting, you might hear the screams and calls of the chimps coming closer. Chimpanzees share about ninety eight percent of their genes with humans. Their actions and noises can seem very human. Being able to watch these animals playing, eating and communicating with each other in the wild is a special experience to treasure. (MUSIC)VOICE ONE:Chobe National Park in Botswana is another popular place for safari travel. This park is home to one of the largest elephant populations in the world. Mist Setaung is a professional safari guide who often takes visitors through Chobe. Listen as he tells about himself and how he got this exciting job. MIST SETAUNG: "My name is Mist Setaung and I was born and raised in Botswana, a place called Maun which is a gateway to the Okavango delta. To become a guide you actually go through a course. There's a six-month course of the Department of Wildlife, which is run by the government. Then, after this course you take an exam. My father offered me a job as a trainee guide and I went into the bush. Slowly and surely I started learning and eventually it got into my blood, and I just got devoted to it."VOICE TWO:With a guide like Mist you are guaranteed to see new animals and learn agreat deal. One excellent way to see the wildlife of Chobe is by boat. Mistcan take you on a boat ride up and down the river so you can see theanimals as they come to drink or play in the water.Hippopotamuses like to stand in the grass and eat most of the day. Or,they enter the water to stay cool. In fact, a hippo can stay under water forup to six minutes. They are very good at hiding in the water. If you lookcarefully, you can see their two eyes looking out of the water at you. Youknow they are near when you hear the strange deep noise they make withtheir nose.(SOUND)These animals look too big and fat to be dangerous. But they can be very aggressive and protective of their territory.VOICE ONE:If you do not see any big animals near the river, Mist can tell you aboutbirds instead. He can point out the male paradise whydah with its unusuallylong black tail feathers. Or, he might show you one of many guinea fowl,which he jokingly says are also called "Chobe chickens." He can even make noises that sound just like the birdcalls.VOICE TWO:There are also many smaller animals to watch for. Antelopes of all kinds live in the park. There are gnus or wildebeests with their flat wide faces. Fine-boned impalas walk around as gracefully as dancers. Solid warthogs explore the bush on their short little legs. These strange-looking wild pigs are dark with long yellow tusks coming out of their mouth. They are not very pretty animals. Mist says "they have a face only a mother could love."Mist can also tell you about conservation efforts to protect wild animals. Some animals such as the black rhinoceros have almost been destroyed because poachers illegally hunt and kill them. Many parks across Africa have had trouble with poachers. In Chobe there is an army camp with workers who make sure that poachers stay away.VOICE ONE:It might surprise you that there are too many of some other animals. For example, in parts of Chobe the large elephant population has actually harmed the environment. When elephants eat huge quantities of leaves and grasses, other animals have trouble finding enough food to eat. And,elephants are not gentle eaters. They can tear out trees and bushes as they feed. In the dry season these dead plants can increase the danger of fires.VOICE TWO:If you are lucky, you can enjoy sunset while floating down the Chobe River.Yellow and orange colors fill the sky at this hour and are reflected in thewater. The sun slowly starts to slip behind the trees. But before it is dark,you see a large movement of gray bodies. Three families of elephants havecome to the water's edge.More than thirty elephants are quietly drinking and eating. There are hugeold elephants with large tusks. There are the mothers who lead each familygroup. Then, there are the babies who play and run around the thick legsof the adult elephants. The elephants look up and watch as your boat turnsaway and you head back to camp at the end of another day on safari in Africa.A hippopotamus eating lunch A paradise whydah Chobe elephants at sunset(MUSIC)VOICE ONE:This program was written and produced by Dana Demange. I'm Steve Ember.VOICE TWO:And I'm Barbara Klein. You can read and listen to this program on our Web site, . Join us again next week for EXPLORATIONS in VOA Special English.。

未来的探险活动作文英文回答：Exploring the unknown has always been a fascination for me. The idea of venturing into uncharted territories and discovering new things is both thrilling and exhilarating. Whether it's diving into the depths of the ocean, trekking through dense jungles, or scaling towering mountain peaks, the sense of adventure and the unknown never fails to captivate me.One of the most exciting future adventure activities I look forward to is space tourism. With the advancements in technology and the increasing interest in space exploration, the possibility of civilians traveling to space is becoming more of a reality. Imagine being able to float in zero gravity, witness the Earth from a completely different perspective, and experience the vastness of the universe firsthand. It's a dream that many have had for centuries, and it's incredible to think that it may soon become areality.In addition to space tourism, I am also intrigued by the idea of deep-sea exploration. The ocean covers more than 70% of our planet, yet we have only explored a small fraction of it. The mysteries and wonders that lie beneath the surface are endless, and the thought of being able to dive to the deepest parts of the ocean to uncover its secrets is truly captivating. From discovering new species to uncovering ancient shipwrecks, the potential for exploration and discovery in the deep sea is boundless.Furthermore, the concept of eco-tourism in remote and untouched regions of the world is something that I am eager to experience in the future. Whether it's trekking through the Amazon rainforest, exploring the Arctic wilderness, or venturing into the heart of the African savannah, the opportunity to immerse myself in the natural beauty and diverse ecosystems of these regions is a prospect that excites me. Not only would it allow me to appreciate the wonders of nature, but it would also provide a deeper understanding of the importance of conservation andpreservation.中文回答：对未知世界的探索一直是我着迷的事情。
