Discuss the debate words that the advantages outweigh the disadvantages and the disadvantages outweigh the advantages.

An argument that the advantages of exploration outweigh the disadvantages.

Because through exploration, we can better develop the earth's resources and contribute to the civilization and progress of society! Moreover, it is a challenging activity, full of excitement, which makes people live more meaningfully and proves the value of life! The Antarctic expedition is an example. The Antarctic scientific research reactor led by Scott, with the spirit of human exploration of the earth and the hope of the people of the motherland, went to the South Pole step by step and reached the South Pole. After all, the most challenging and exciting difficulty. Their spirit and quality have been sublimated! Yes, they finally failed to overcome the climate and were buried in the frozen Antarctic continent forever! But their spiritual quality has inspired generations of new people. Through the diary, human beings have a deep understanding of the climate in Antarctica. By studying rock samples, humans have learned about the geology of Antarctica and realized that there are a lot of natural gas and minerals there. It has made mankind's understanding of Mother Earth a big step forward.

Why do some people like to explore?

This is related to a substance called dopamine in the human brain. Dopamine is a substance that can make people happy. When the brain secretes this substance, people will feel happy.

A dangerous state will make people in a state of high vigilance and excitement, at which time more dopamine will be secreted. Adventure will make people feel happier than usual. That's why so many people go exploring.

Exploration is an act of conquering nature, but you need to fully understand nature and have the ability to conquer it. Successful exploration can build strong self-confidence, because exploration is often difficult to do. Exploration can personally experience the smallness of human beings, thus cherishing life. Exploration is also exploration, which is the difference between humans and animals. Without this spirit, human beings cannot evolve into human beings.

In the long history of mankind, there are six magical explorers whose adventures may have changed the whole world!

Today, these short stories and those terrible experiences are more like a series (some of them have indeed been made into movies or TV series): whether in the rough sea or in the dry and hot desert, these six fearless explorers bravely faced everything and finally discovered places on earth that no one knew before.

If you think they are nothing-just someone fighting the lion and someone swallowing the mouse ... then, if you have the courage, you can also explore! ……

Pang Si Delean: Discovering the "Land of Sunshine"

Adventure: Discovery in Florida

Time: 15 13 ...

There was once a legend that there was a spring called the fountain of youth, and the first person who tasted the fountain of youth would get wealth, fame and a chance to be young again. But the problem is that no one knows where the legendary spring is.

Spanish explorer Pang Si Delean set sail from South America and sailed all the way to Turkish Island and San Salvador Island, but he didn't find it. Although Pang Si didn't find the fountain of youth, as the first European to set foot on this land and named it "Florida of pascua" (which we call Florida today), he did gain wealth and fame.

Kyle Poirot: Walking into China

Adventure: One of the first Europeans to visit China.

Time: from 127 1 year.

In the Middle Ages, when other friends were still addicted to marbles, Kyle Poirot's father and uncle asked him if he wanted to ride with them from Italy to China. Now, let's look at the really incredible thing: this adventurous 17-year-old boy agreed without hesitation!

Kyle said that during the trip, he seemed to hear the call of death in the desert. But in the huge and brilliant Yuan Dynasty (the capital of the Yuan Dynasty), he felt that it was all worthwhile. Because everything is so magical: paper (coins) used to buy things, colorful tattoos, rhinoceroses like unicorns in mythology …

Kyle wrote this trip into a very popular book, The Travels of Marco Polo. Later, it was this book that inspired the adventurous spirit of another Italian youth: Christopher Colombo.

Ferdinand Magellan: Traveling around the world

The achievement of exploration: the first voyage around the world.

Time: from 15 19.

In Ferdinand Magellan's time, people believed that the earth was round, but no one proved this fact by traveling around the world. Therefore, proving the shape of the earth became Magellan's unshirkable responsibility.

The terrible storm almost destroyed his fleet. Because of the shortage of food, he and his team members had to feed on the mice on board. Three years later, only five ships made it to the finish line. It was these ships that brought back the first warriors who sailed around the world.

David Livingston: "Breaking into Africa"

Achievements of the expedition: the first visit to Central Africa.

Time: 184 1 year to 1873 year.

For Scottish doctor and missionary David Livingston, crossing the deserts, rainforests and barren hills in Africa means realizing his dream. He once struggled with a lion and almost lost an arm; He discovered one of the largest waterfalls in the world and named it "Victoria" after the Queen of England.

He lost his sight on the way to find the source of the Nile. Five years later, reporter Henry Stein found Dr. Livingston in front of a small hut and put forward the famous slogan: "Dr. Livingston, I want to do it!" " This slogan inspired countless later explorers.

Robert Peary: To the North Pole.

The first to reach the North Pole.

Time: 1909

Robert Peary went north with his trusted partner Mather Hansen (another talented explorer) and four other team members. On the way to the North Pole, they eradicated the ice peak at an altitude of 15 meters, endured extremely cold weather and encountered endless fog, as if it were black smoke burning in the whole North American prairie.

When they finally reached the North Pole, Piri, who was in rags, was very excited. He waved the American flag sewn by his wife and really felt that he was on top of the world.

Rod Amundsen: Arriving at the South Pole.

Achievements of exploration: the earliest arrival at the South Pole.

Time: 19 1 1 year.

On the way to the North Pole, Rod Amundsen suddenly decided to go to the South Pole. Because he thinks it is "cooler" to be the first person to reach the South Pole than to inspect the developed land. "I will hit you there!" Amundsen told the news to his rival robert scott, an explorer on his way to the South Pole.

In the coldest place in the world, Amundsen glided on the snow-covered wasteland by dogs dragging sledges. Facts have proved that this is a wonderful idea. Because Scott chose a pony as a means of transportation, the result was terrible, and the horseshoe kept slipping on the snow. Finally, Amundsen Biscottes arrived at the South Pole four weeks ahead of schedule.

Christopher and Columbus (145l- 1506) are famous Spanish navigators and pioneers of great geographical discoveries. Columbus was a believer in the theory of the earth's sphere when he was young. He admired Kyle Poirot, who had been a prisoner in Genoa, and was determined to be a navigator.

He crossed the Atlantic Ocean four times from 1492 to 1502 and discovered the American continent, so he became a famous navigator in history.

Columbus was an Italian, and he liked sailing adventures since he was a child. He has read Kyle Polo's travels, and he really wants to go to India and China. At that time, the theory of the earth circle was very popular, and Columbus also believed it. He successively asked the kings of Portugal, Spain, Britain, France and other countries for financial aid to realize his plan of sailing westward to the eastern countries, but all of them were rejected. On the one hand, the theory of "Earth Circle" is not perfect, so many people don't believe it and regard Columbus as a charlatan. On one occasion, at a special review committee on the Columbus Plan in Spain, a member asked Columbus: Even if the earth is round, sailing to the west can reach the east and return to the port of departure, then a voyage must climb from below the earth. How does a sailboat climb up? On this issue, the eloquent Columbus was speechless. On the other hand, at that time, besides traditional silk, porcelain and tea, the main demand of western countries for oriental material wealth was spices and gold. Among them, spices are essential materials for daily life and cooking in Europe, which are in great demand and are not produced locally. At that time, these commodities were mainly transported by traditional land-sea combined transport routes. The vested interests of these commodities also strongly opposed Columbus's plan to open up new routes. Columbus lobbied for his plan for more than ten years. It was not until 1492 that the Queen of Spain had a vision for heroes. She persuaded the king and even gave her private money to help Columbus, so that Columbus's plan could be implemented.

1on August 3rd, 492, Columbus was sent by the king of Spain, with the credentials of Indian monarch and emperor China, and led three sailboats with several hundred tons to sail out of the Atlantic Ocean from Barros, Spain, and headed west. After 70 days and nights of hard sailing, land was finally found in the early morning of 1492+00+02. Columbus thought he had arrived in India. Later, I learned that the land Columbus landed on belonged to the Bahamas in the Balebi Sea in Central America, and he named it San Salvador at that time.

On March 1493, Columbus returned to Spain. After that, he sailed west three times and landed on many coasts of America. Until 1506 died, he thought he had arrived in India. Later, an Italian scholar named Amerigo, after more investigations, realized that these places Columbus arrived in were not India, but a new continent that was unknown before. Columbus discovered the new continent. However, this continent is named after the person who proved that it is a new continent: America.

Later, there were many whispers about who first discovered America. The conclusion that Columbus discovered the New World is beyond doubt. This is because people in Europe and even the whole old Asia-Africa continent really didn't know there was this continent on the other side of the Atlantic. As for who arrived in America first, that is another question, because Native Americans themselves immigrated from Asia in ancient times. It is also possible for China and Oceania to sail to America, but none of these can change the fact that Columbus discovered the new continent.

Columbus's voyage was the beginning of the era of great navigation. The opening of the new route has changed the course of world history. It shifted the route of overseas trade from the Mediterranean to the Atlantic coast. From then on, the West finally walked out of the darkness of the Middle Ages and began to rise in the world with an irresistible trend, and in the following centuries, it achieved maritime hegemony. A brand-new industrial civilization has become the mainstream of world economic development.

The significance of exploration can refer to the significance of field trip.

1. Life lies in exercise

It is a well-known truth that life lies in exercise, which makes people evergreen. Especially the "work bugs" who have lived in cities for a long time (the names for some people who can only work but can't relax) and the white-collar workers who have been engaged in mental work for a long time are more meaningful. Everyone agrees with the health functions of some daily sports activities, such as playing basketball, table tennis, running and swimming. Traveling and hiking in Shan Ye during holidays can also play a role in keeping fit. The former is less limited by time and space, but its activities are relatively simple; The latter has certain requirements and conditions for time and funds, but its benefits are incomparable to the former. Of course, actively carrying out various forms of sports is worth vigorously promoting. Outing is a comprehensive cultural and sports activity, which is manifested in the need to physically lift feet, climb mountains and do all kinds of chores that are rarely done. Cultural activities are more abundant. It can be said that sports activities are carriers and cultural activities are content in a higher sense.

return to nature

With the high modernization of urban life, people are far away from nature, and everything they come into contact with in life is man-made objects. People live in concrete jungle instead of forest, and the smell of artificial radio waves, electroacoustic, electro-optical and artificial objects is everywhere. What is more serious is the by-product of human civilization-the serious pollution of industry and life. The human body is a natural thing, but people live in an unnatural environment. Long-term contact with nature has an impact on human health, which has long been verified. Therefore, returning to nature has become a widespread trend in the world in recent years. Go to nature to feel the natural magnetic field, natural beautiful voice, fresh air, clean water, warm sunshine and gentle moonlight. Only by going to nature often can we live like children of nature, not robots.

Increase your knowledge

When traveling, we must leave our familiar environment, and we must contact new things and environments voluntarily or involuntarily, which enriches our life experience and increases our knowledge. Some insights may have been seen in books, movies and TV plays, but if you don't take action yourself, there will always be superficial understanding. The ancients said, "Read thousands of books and follow Wan Li Road" and "Do it without knowing it" is the truth. And there is a lot of knowledge and experience that can't be obtained and learned from books. Isn't it a wonderful thing that we have increased our knowledge and enriched our life experience during our trip? With a rich life, we can not waste our lives and have "material" to brag to the younger generation. You didn't know that auricularia auricula was born from rotten wood until you reached Whitehead.

Relaxation of body and mind

In our modern life, driven by survival and development, people are always busy for their livelihood. The fast-paced and efficient modern life makes people's nerves and lives highly tense. Living like this for a long time, people's horizons become shallow, their psychology develops abnormally, their bodies are prone to various modern urban syndromes, and their health is getting worse and worse. People are eager for complete relaxation of body and mind and healthy mental state. Although there are many similar industries in the city that serve this purpose, such as sauna, various massages and some entertainment activities, most of them are superficial, temporarily relaxing, and treating the symptoms rather than the root cause. The best way to really relax and adjust your mind is to return to nature and stand on the top of the mountain to see the world. "Clouds Wangfu? My chest is free and easy, and the mountains are small. " That kind of feeling should be extensive, and the disputes in the world, the gains and losses of fame and fortune, the gains and losses of honor and disgrace will all fade away, so as to realize what is "nothing", what is "inaction" and what will be experienced. When you return to the city, you will laugh more and worry less. Of course, we should actively adjust ourselves, know ourselves, transform ourselves, draw new ideas and new energy from nature, and put ourselves into a more meaningful era and the pace of life.

make friends

Traveling abroad, it has its unique significance to pursue the past alone, but it is more meaningful to travel with some like-minded friends. Most of the traveling partners are like-minded people from different units instead of colleagues and classmates who live together day and night, which not only provides a good opportunity to make friends and expand social contacts, but also allows them to exchange and discuss various issues and information of mutual interest. Because everyone always wears a "mask" in their daily work, once they are in an irrelevant environment, they will open their hearts to each other and get along freely, and their true feelings will be revealed naturally. The friends they make in such an environment are always long-lasting and sincere. If we go through a relatively hard field trip, in the process of helping each other and overcoming various difficulties, the spark of friendship and even love will come out in generate in Generate. All kinds of "Romance on Lushan Mountain" and "Love on Huangshan Mountain" will be staged.

Of course, there may be a few people with various "problems" who join in and become the "sparks" of disharmony in travel. Everyone should try his best to help him improve. Of course, if he is stubborn, he will have to see a psychiatrist.

Cultivate emotion

It goes without saying that when we travel with the desire to return to nature, visit nature, get close to nature, make friends, exercise and increase our knowledge, we are also cultivating our sentiments and interests. The ancients said, "The benevolent enjoys its mountains, while the wise enjoys its water.". Crossing mountains and rivers to cultivate sentiment has long been a life pursuit of the ancients. The ancients did this, and today's people should carry it forward.

7. Survival skills

People who live in cities can't just adapt to city life. In the wild, they are at a loss, don't know the edible plants, can't make a fire on the spot, cook by themselves, and can't tell the direction. If you don't know all the knowledge that a natural person should have, once you leave the familiar life in the city and go to the wild, even if you have gold and silver treasures, you will face a realistic survival problem. Survival of the fittest, death of the unfit. In foreign countries, field survival education is more common, and some have courses from primary school. So this book introduces some knowledge of field travel and survival. On the basis of study, often going to outdoor activities will explore the skills of survival in the wild. Once it happens, you can deal with it in a helpless environment in the middle of nowhere. No one can guarantee that it won't happen in this life.

8. Understand the national conditions

In China, the gap between urban and rural areas will be great for a long time. As people who live in cities, they should not only see their own living environment, but also have no perceptual knowledge of the lives of their compatriots in rural areas. It is impossible to understand the national conditions of China without understanding the countryside. China is a big agricultural country, with 90% of the population in rural areas, and there are still many rural people who have not solved the temperature problem.

Full of problems, living conditions are still very poor. As a China person, it is very important to know our national conditions. Whether working in a government department or an enterprise, without a correct view of national conditions, government decision-making and enterprise management can not be done well. It is impossible to understand the national conditions without going to the countryside, especially some poor villages. Therefore, when we travel to the countryside, we can't just care about our own travel life. It is a bad thing not to enter the village, not to visit the village, to be close to the peasant brothers and to be relatively silent. In fact, it's just a question of going the right way, gaining more understanding of national conditions and people's feelings and some unexpected gains. If we can let our children know and understand our national conditions with us, especially in rural areas that are still on the poverty line, we may not have to teach them how to work hard and how to live frugally.

The fun of field trips in the second quarter

1. Landscape Aesthetics

A great purpose of field trip is to feel and know the beauty of nature, which is not only the significance of field trip, but also one of its greatest pleasures. Nature is full of beautiful "elements". For us, learning and understanding the beauty of nature is a high-level gain. If summed up, the "elements" of natural beauty have the following aspects:

Formal beauty: Everything in nature has its own unique form, line and shape. , they constitute the overall form of different classifications in nature. Such as mountains, hills, canyons, rivers, Gobi and so on.

Color Beauty: The colors of all things in nature are ever-changing and colorful: colorful neon, green Yuan Ye, flowers with different colors, blue rivers, etc. The colors of all things in nature are not only colorful, but also constantly changing. This is something we can't see in the city.

Wonderful sounds: thrilling thunder and lightning, worrying raindrops, waterfalls, pine trees, water, birds singing, apes singing, autumn insects singing and so on in Ma Benteng. Without these wonderful natural sounds, it is hard to imagine what kind of world human beings would live in.

Dynamic beauty: clouds surging, tides rising and falling, sun and moon alternating, waterfalls flowing, etc. Especially people's favorite sunrises, sunsets, rapids and waterfalls. Is the dynamic beauty of nature.

2. Observe and understand biology

Knowing and appreciating all kinds of creatures not only enriches our understanding of nature, but also is a kind of natural aesthetics. There is a lot of fun in it. We should know what animals and plants are by classification. What are mammals, birds, insects, reptiles and aquatic animals? What are their characteristics, how to distinguish them and so on. We will appreciate the beauty of biology from contact and viewing, and feel endless fun from it.

3. Harvest the gift of nature

Traveling in nature, as long as we pay attention, we will find many natural things worthy of our collection: all kinds of roots, crystal clear rain flower stones, leaves of different shapes, and even precious Chinese herbal medicines, strange stones, antiques and so on. These natural gifts and its history can only be obtained through a little effort. When we take them home, we can not only taste and recall them, but also publicize our harvest to our friends.

4. Appreciation of folk customs

China is a multi-ethnic country, and 56 ethnic groups have their own unique national customs, festivals and customs. Many festivals and customs are our envy. To appreciate the rich national culture and customs of all ethnic groups, only by going out of the city and going to rural areas and ethnic villages can we really get in touch with them. Knowing all ethnic groups in China is not only the significance of traveling, but also the understanding of national conditions, and it is also one of the pleasures of field travel.

5. Exciting feeling

Living in the city for a long time will make you feel that life is dull and vulgar. If people's life goes on like this, it must be terrible. Of course, we can also feel some poor stimulation from entertainment activities such as movies and TV, but that is never comparable to enjoying nature. We can enjoy all kinds of thrills and thrills of nature. Cave exploration, canyon hiking, mountain climbing, jungle exploration, river rafting, jumping, diving, rock climbing and other outdoor activities will experience all kinds of thrills.

6. The source of literary and artistic creation

Literary works handed down from ancient times must come from life, and you can't write good literary works behind closed doors. This is true for literary writing, especially for art and photography creation. Traveling to rural and ethnic areas, paying attention to and understanding their lives can accumulate writing materials. Music students can collect valuable music materials from rural areas and ethnic compatriots. Friends who love art and photography are promising. Most of the award-winning works of art and photography come from nature and rural areas, which is a reward for creators who go deep into life.

The fun and significance of traveling should go far beyond this. As long as we face everything we will encounter with love, sincerity and curiosity, you will find the deeper meaning of life and the charm of nature. Let's act! After all, it's time to return to nature.

The disadvantages of exploration outweigh the advantages.

Because exploration is a double-edged sword, wherever human footprints go, they belong to people. In fact, wherever human footprints go, it is when disasters happen. The source of Mount Everest and the Yangtze River has been polluted, and the animals there are restless when people enter and leave the virgin forest. Therefore, we believe that wherever human footprints go, they will be covered with dust and bring disaster. "

Ladies and gentlemen, have you forgotten the saying that knowledge is infinite and life is limited? Then, this is also related to our topic today-exploration. Does exploration have more advantages than disadvantages? Or do more harm than good? If exploration can bring great progress to mankind, then our society today will be a peaceful and quiet world, but we have not fully realized it. If exploration is your sacred cause, why don't your family and yourself try something so great, so sacred and so beneficial to today's society? If the opponent's friend says yes, then we will tell you today that the various disadvantages of exploration and the nature of exploration are dangerous, extreme and unnecessary. This is our view, exploration-the disadvantages outweigh the advantages. Here I make a preliminary argument.

From an economic point of view. You can count, every time we explore, we exclude rewards for every explorer, such as climbing mountains. Once down, meals, medical expenses, all kinds of mountaineering equipment, such as oxygen, hiking shoes, positioning system for mountaineering, etc. , all need an immortal investment. Instead of putting these funds on other things that are more powerful than exploration, such as education, architecture, commerce, diplomacy, and science and technology, these benefits far outweigh exploration. Didn't they promote human development faster and better? Why put these funds on this risky project with little material benefits? As Scott said, are we just fighting for a newcomer, or are we trying to satisfy this spiritual pleasure and satisfaction? In front of me, I am only relative to a successful explorer. What if I fail? Wouldn't it be more disappointing to be in a mess? As an explorer, I have to use hundreds of words to scold myself that I am incompetent, which not only makes me feel guilty for the loss of my country, but also regrets the result of my wasted efforts. This may not be enough. What if the explorer dies unfortunately during the expedition? In this dangerous adventure, dead people often happen. If measured by money, then what we lose is a number that cannot be measured by money. Because life is priceless.

Psychologically speaking. Although these explorers are out of their own will, their own hobbies and persistence in adventure. They can do this, or they can devote themselves to exploration, and maybe they will feel a little satisfied. However, we should also understand that we live not only for ourselves. Indeed, there are many people in the world who care about us, such as our parents, friends, lovers and opponents ... If a person only cares about his hobbies and ambitions, regardless of the feelings of others, such people tend to take crazy risks; If someone has a high sense of responsibility and thinks of others, such a person will think twice about this ridiculous project. For example, Scott explored the polar regions, and he eventually died in the line of duty. At this moment, can we imagine how sad you would be if you were any member of the Scott family? Even, this tragedy will make you sad for life. In this way, the explorer not only brought misfortune to himself, but also brought many misfortunes to all who cared about him. If I were his father, first of all, from an objective point of view, I would really be proud of having such a child, but I hope that this is not the case after all. I would rather he was a farmer, sowing food in his name than die. I'm sure you are, too. Therefore, exploration is an extremely dangerous project, which is painful and sad.

Maybe everyone will say, "Isn't our globalized society the development of explorers in the past?" ? And our advanced technologies today, such as aerospace technology and mountaineering technology, are not bought by countless explorers with the value of their lives? These little problems are nothing.

However, if you think deeply, can you think deeply besides the implication of "wasting a lot of time" and "wasting a lot of money" in the textbook and the above-mentioned point of "causing mental shock to relatives"? To some extent, exploration is the product of the concept of "anthropocentrism". This concept holds that in the face of nature and its biological world, human beings can set foot everywhere, and as long as they can, they can "occupy the mountain as the king" and "insert the flag of Xinjiang" and take it for themselves. However, if we go beyond the thinking frame of "anthropocentrism", we can question: Is there no limit or restriction for human steps? As long as human footprints are gone, must they belong to human beings? Should it be dominated by humans? In fact, when the footprint of human exploration arrived, it was also the day when the disaster happened there. Isn't it? Humans fly into space, and the garbage in space has surrounded the earth; Man has climbed the Himalayas, the top of the earth, and today the source of the Yangtze River has been polluted. When humans enter and leave the primeval forest, the "indigenous" animals and creatures there are disturbed and violated, and even extinct ... Just as Columbus's exploration of the "New World" brought about the expansion of colonialism, today's "exploration" of human beings without self-discipline and restrictions also reflects the expansion of anthropocentrism. Science is a double-edged sword, so is exploration. Human exploration will leave dust where it leaves footprints. Can you say that these are also miracles brought about by the so-called great spirit of adventure? Don't, standing in front of countless exhaust oxygen tanks on Mount Everest, can you euphemistically say that this is called sacrificing the ego to complete the ego? Don't, standing in front of the human products of those exhaust gases on the snow-white ground in Antarctica, can you euphemistically tell everyone: Is this a great tragedy?

In this case, if people all over the world explore, it is conceivable that we are likely to coincide with the idea of "human war" in a famous movie "The Matrix" today.

So we feel that exploration-the disadvantages far outweigh the benefits.
