Now, our technology is developing faster and faster, and something is invented every day. There are all kinds of contact lenses, PDA. Is the development of science and technology beneficial or harmful? The key is how people use it. I think the development of science and technology is beneficial. Why do I think it is beneficial? Because the development of science and technology, coupled with the correct use of people, can bring benefits to everyone. Why not?

Now we all know the peaceful use of atomic energy. But in the beginning, people studied and used it to make weapons-atomic bombs. The atomic bomb is a nuclear weapon that can release huge energy instantly by using nuclear energy. They are also called fission bombs. The power of atomic bombs is usually several hundred to tens of thousands of tons of TNT equivalent, which is very destructive. In World War II, the United States dropped two atomic bombs on Japan, killing countless people. Now, atomic bombs are used more.

Like having a computer. Searching information online, watching news, increasing knowledge, scientific calculation and data processing, word processing, entertainment, auxiliary education and computer-aided design are of course beneficial to us, but they also have disadvantages. If we play games online or visit bad websites, it is not good. In other words, computers are good or bad for everyone. It is good for searching information online, watching news, increasing knowledge, scientific calculation and data processing, word processing and entertainment. It's not good for those who play games online and go to bad websites. This is a question of whether the user uses it correctly.

Therefore, everything in the world has two sides, a good side and a bad side. Whether it is good or bad is up to the user. The same is true of the development of science and technology, and its advantages and disadvantages are also determined by users.

(2) Title: The advantages of science outweigh the disadvantages-recommendation

Let's compare today's life with that of 10 million years ago, and we are supreme; Comparing today with thousands of years ago, we are condescending; Comparing today with hundreds of years ago, we are happy and comfortable; Comparing today with tomorrow, the future is bright. For thousands of years, it has changed from a carriage to a car, train and plane. From kerosene lamps to incandescent lamps, neon lights and energy-saving lamps; From the ends of the earth to close at hand, video chat and mouse know everything about the world.

We are happy, we are lucky, and we have caught up with an era of rapid development of science and technology, an era full of high technology. This is not only because our ancestors chose development and progress in evolution, but also because of the unremitting efforts and hard work of all people. How many hard-working scientists have bought it with their wisdom and even their lives today.

Because of Faraday, our life is full of all kinds of electrical appliances; Because of Darwin and Mendel, we can know ourselves better and know ourselves; Because of Bian Que, Hua Tuo and Li Shizhen, our life is guaranteed.

Didn't they buy everything around us? Life is so comfortable, life is so pleasant and life is so wonderful. Our average life expectancy is 30 years higher than that in ancient times, and we don't even have to go out to visit relatives and friends. Isn't this all the benefits of scientific development?

Therefore, science and technology change history, and we don't need to question whether the development of science and technology is beneficial or harmful, because it is beneficial! Rita! Rita! You said that the development of science and technology has brought air pollution, you said that the development of science and technology has produced white garbage, and you said that the development of science and technology has caused the warming of the temperature ... Everything can't be perfect, and the darker the shadow behind the brighter place, but on this basis, you can draw the conclusion that the disadvantages of science and technology development outweigh the advantages? Different times lead to different problems. Except air pollution, all provinces and cities have put forward prevention plans. White garbage, unified treatment; Automobile exhaust causes the temperature to warm up. Scientists have also developed solar-powered cars. Now, solar water heaters, solar air conditioners, solar cells ... environmentally friendly and economical solar energy has gradually entered thousands of households. Isn't this the development of science and technology?

Although there are disadvantages, it is irrelevant compared with the scientific and technological development concept of benefiting mankind and protecting home. As long as there are drawbacks, scientists will try to solve them. We can't stop the pace of scientific and technological development for a while because we are choking on food. The development of science and technology is understandable and beneficial. This is the only answer to this argument! Just because science and technology have been advancing and science has been developing, cunning sophistry, generalization and unreasonable entanglement can't change this truth.

If you say that the development of science and technology does more harm than good, can you come to class without a car, gel pen, ballpoint pen and pen within a week? Can you stop watching TV, listening to the news, reading newspapers, reading books and surfing the Internet for a week? Can the developed hybrid rice not be eaten for a week? No spaghetti? Don't drink? No, no and no, because technology is closely related to you and inseparable from you! Now if you write to the chairman and suggest stopping all scientific research activities, will everyone send you flowers or the board of directors shoot you exclusively?

Technology has really changed history. Without it, our life is unimaginable. Our days are dark. It was the development of science and technology that saved us, and it was science that saved us from the hydrothermal era. We should fear him. How can we say that the development of science and technology is full of drawbacks?

Science and technology change history, and knowledge changes destiny. We have entered 2 1 century and entered an era full of high technology. Science has changed our lives and changed our destiny. "Knowledge is power", as a big country with a population of 65.438+0.3 billion, why can it stand in front of the world? Because our technology is constantly developing! Our technology is constantly improving!

The advantages of scientific and technological development outweigh the disadvantages, which is an eternal theme!

On March 24th, 2009, our Class 63 held a debate in the classroom. The central topic of the debate was "Is the development of science and technology beneficial or harmful". The advantages outweigh the disadvantages. Billy thinks he is against it, so I am one of the opponents.

With the beginning of class, the teacher gave the order and the debate of Class 63 began. First of all, Zhengfang will talk, "We think that the advantages of scientific and technological development outweigh the disadvantages. If we don't have a car now and don't have the technology now, then our life will become very difficult. " Fang Tao also opened the first page and began to speak. The debate began here. Next, the opposing students spoke, "We think that the disadvantages of scientific and technological development outweigh the advantages. If ... "

In this debate, I was most impressed by three people, who were attracted by their serious and humorous language every time.

Classmate Wei Yu is anti-Party. She impressed me the most. "We believe that the advantages of scientific and technological development outweigh the disadvantages. Do you promise not to destroy the environment if you live in ancient times? " Founder Wang Shu spoke, and Wei Yu retorted: "Now there are only facts, no ifs!" Wang Shu went on to say, "If you were in ancient times, wouldn't you cut down trees to build houses?" Outland immediately stood up: "I said, only facts, no ifs!" " "The applause from the other side was deafening. I kept clapping and cheering for her spirit and her firm language!

Good classmates, also anti-Party, gave me the impression of two words: humor! "If you didn't have to live in a house made of wood in ancient times, where did you live?" As soon as the positive side finished speaking, the negative side replied, "So ... you live in a cave!" " The whole class burst into laughter, and the teacher laughed from ear to ear. "Opposing classmates, why do you say that you are talking about living in a cave?" It also made the whole class laugh up and down. Good students can't express themselves very well, but they are very active in answering questions, which adds a lot of glory to the opposition!

Yu Ting's classmates, needless to say, are also our own. He impressed me with a little humor and seriousness. "How can I get there if I don't have to go by car?" The positive image threatens us against the other side. "Then you can go!" Yu Ting's answer stunned the whole class, and after a while, the whole class burst into laughter again. My God, a classmate whispered below, "Will you walk to Haikou on your own when you travel?" Ha ha ha ... Why are you serious? Because, when Yu Ting said it, she meant it!

This debate is really interesting! Although we are opponents in the debate, we are still good friends after class. From this, I understand: winning or losing comes second, friendship comes first!

Scientific development. Is it beneficial or harmful? Is the development of science and technology beneficial or harmful?

Now, our technology is developing faster and faster, and something is invented every day. There are all kinds of contact lenses and PDA. And is the development of science and technology beneficial or harmful? The key is how to use it. And I think the development of science and technology is beneficial. Why do I think it's Rita Because the development of science and technology, coupled with the correct use of people, can bring benefits to everyone. Why not do it?

Now we all know the peaceful use of atomic energy. But in the beginning, people studied and used it to make weapons-atomic bombs.

The power of atomic bombs is usually several hundred to tens of thousands of tons of TNT equivalent, which is very destructive. During World War II, the United States dropped two atomic bombs on Japan, killing countless people. Nowadays, the purpose of atomic bombs is more to build nuclear power plants, convert nuclear energy into electric energy and make contributions to mankind.

And computers. It is certainly beneficial for us to look up information, watch news, increase knowledge, scientifically calculate and process data, word processing, entertainment, auxiliary education and computer-aided design. But there are also some shortcomings. If you play games online and go to bad websites, that's not good. In other words, computers have advantages and disadvantages for everyone. It is beneficial to searching information, reading news, increasing knowledge, scientific calculation and data processing, word processing, entertainment, auxiliary education and computer-aided design on the Internet. It's not good for those who play games online and go to bad websites. This is a question of whether the user uses it correctly or not.

Therefore, everything in the world has two sides, a good side and a bad side. Whether it is good or bad is up to the users themselves. The same is true of the development of science and technology, and its advantages and disadvantages are also determined by users.

Debate: Is it beneficial or harmful to write a 600-word composition? You have to say what it is. For example, the following model essay tells the advantages and disadvantages of science.

Disadvantages of science

1. Humans rely on scientific achievements without thinking.

Turn someone's head into treasure,

Become lazy,

Reduced labor force,

Most people are on the verge of being fired.

1: Environmental pollution. This is the most direct and obvious disadvantage.

2. Species extinction is accelerating. This is the development of science and technology caused by environmental pollution and human killing.

shortcomings

3. Personal safety is increasingly insecure. There are now tens of thousands of crimes on average every day.

Most of its criminal means are related to the current new technology, especially gun-related crimes, which ordinary people can't prevent. From the Second World War, we can already see that with the development of science and technology, the damage and losses caused by the current war are far from comparable.

It may even lead to the fate of human extinction.

Human's physical quality is not as good as before. With the development of science and technology, the emergence of vehicles such as air cars, trains and planes has greatly changed human daily life. Human beings are no longer always dependent on their own legs, so the physical quality of human beings is not comparable to that in the past. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers". If this situation continues to develop, it may make people's limbs atrophy and make people.

A new form has emerged.

5. All kinds of emerging germs appear constantly, and the lethality of many germs has far exceeded the destructive power of previous germs. This is because the rapid development of medical science and technology has accelerated the mutation of virus, so that the development speed of science and technology can not keep up with the mutation speed of virus. Maybe one day mankind will perish because of a great plague.

ring

Environmental pollution. This is the most direct and obvious disadvantage. People always think that the land, sea and air on the earth are endless, so they never worry about sending tens of millions of tons of waste gas into the sky and dumping hundreds of millions of tons of garbage into the ocean. Everyone thinks the world is so big. What kind of waste is this? We were wrong. In fact, although the earth is large (with a radius of more than 6,300 kilometers), creatures can only live in the range of 8 kilometers to 1 1 km above sea level, and 95% of creatures can only live in the range of about 3 kilometers in the middle. People have wantonly polluted this limited living environment from three aspects. Marine pollution: mainly crude oil leaked from oil tankers and oil wells, pesticides and fertilizers used in farmland. They pollute most marine lakes. Therefore, not only marine organisms are harmed, but birds and humans may also be poisoned by eating these organisms. Land pollution: garbage disposal has become an important problem in big cities. In the tens of millions of tons of garbage every day, many of them cannot be burned or decomposed, such as plastics, rubber, glass, aluminum and other wastes, which have become the first enemy of urban sanitation. Air pollution: This is the most direct and serious. It mainly comes from carbon monoxide and hydrogen sulfide released by factories, automobiles and power plants. Every day, people get sick of respiratory organs or visual organs because of contact with these dirty air. If we still ignore the warnings of experts, there will be no half an inch of pure land to live in in the future. Species extinction will accelerate. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development. Personal safety is becoming more and more insecure. There are now tens of thousands of criminal acts on average every day. Most of their criminal methods are related to the current new technology. Especially gun-related crimes are hard to prevent for ordinary people. From World War II, we can see that with the development of science and technology, now,

Ask for a composition or diary about advantages or disadvantages, not less than 500 words. Here's the thing.

There used to be such a horror story circulating in major schools.

It is said that there are unclean things in A school. Whenever the fifteenth day of the first month, Lu Xun's eyes will move at the school gate.

All the teaching buildings will be cut off.

The stairs will be changed from the original 13 level to 14 level.

The water from the laboratory faucet will turn red.

And the toilet at the end of 1 building. As long as someone goes in, they will never get out.

So a group of naive children made an appointment to explore on 15.

In the afternoon 12, they arrived at the school gate on time.

Lu Xun's eyes looked at the left, and when he dared not come out, he wrote down whether he had moved.

They came to the classroom and turned on the switch. Isn't it open?

"Deception." A boy complained.

"Look again."

Come to the stairs "1 2 3... 13, right?"

The children began to doubt the truth of the legend.

So they came to the laboratory again, turned on the tap and shiny water came out.

"Too boring! We came for nothing! "

At the beginning, the sense of * * * was eliminated by half.

At last they came to the toilet.

Although the girl said she didn't believe it, she still dared not go in.

So I let little C who just said he wasn't afraid go in.

Look at the watch 1 hour.

Two minutes later, the boy came out.

"Everything is a lie."

The children broke up in discord.

On the way out, a doorman found them and scolded them for staying at school so late. The children ran away.

Little B pays special attention to the stone statue at the door. Yes, his eyes still look to the left

"That's a lie," he muttered.

"Hello little b? Why hasn't Xiao C come back from going out with you last night? " The next morning, little C's mother called to ask.

Little c didn't go to school either.

The children vaguely felt that something was wrong.

So they told their teachers and parents about the adventure in the evening.

Everyone went back to that school accompanied by adults.

"What? Our portrait of Lu Xun always looks to the right. " The headmaster said strangely after listening to the children's stories.

"But we looked to the left when we came yesterday."

It really looks right when you go out. ...

"But there was electricity yesterday."

"There was a power outage in our whole area yesterday ... how did you turn on the light?"

"There are stairs!" The children ran quickly to the stairs.

" 1 2 3... 12?"

"Our stairs have always been 12."

"Impossible! ! ! "

"And the lab," a child warned.

"Go to the lab"

A group of people came to the laboratory. There was a dark red mark under the tap they turned on yesterday.

"It's blood."

"So ... Little C went to the toilet yesterday ..." Everyone felt scared.

"Let's go and have a look." The headmaster also realized the seriousness of the matter.

...

Push the door open. ...

Little C's body suddenly appeared in front of everyone.

Eyes wide with fear

The cut throat is bloody.

Internal organs were scattered in the dry pool. ...

"Ah ..." Little C's mother fainted on the spot.

Several teachers immediately rushed out to vomit. ...

Little b was shocked, too

Just a second before he passed out.

He caught a glimpse of little c's watch.

The pointer stops at 1. ...

At this time, Xiao C went in. ...

By the way, there was no doorman on the night of their expedition. ...

Transfer this post to more than 5 forums so that you won't be haunted by the devil and you can realize a wish.

People who don't reply often reply after midnight. ......

I'm sorry, I hate this, but ... please forgive me. ..

How to write a useful or harmful composition! ? Is scientific development beneficial or harmful?

I agree that the advantages of scientific development outweigh the disadvantages.

Without technology, human life is impossible. Since primitive people, they have no food. When they are hungry, they eat bark and drink human blood. After a long time, mankind finally invented grains such as rice, wheat and highland barley, and people's lives gradually improved.

It is sad that a person does not make progress, and a country will decline without progress: a world without progress is dark. For thousands of years, it has changed from a carriage to a car, train and plane; From kerosene lamps to incandescent lamps, neon lights and energy-saving lamps; From the ends of the earth to close at hand, video chat, use the mouse to understand everything in the world.

Everything has two sides, a positive side and a negative side. You can't just decide the positive side. For example, air pollution, experts have introduced prevention programs; White garbage, unified treatment; Automobile exhaust causes the temperature to warm, and scientists have also developed solar-powered cars.

Developed countries in the world have put forward new low-state economic development models, such as solar air conditioning and solar cells.

Highly developed science and technology will surely solve all the disadvantages brought by scientific development; Will surely bring mankind into a better realm of life; It will definitely transform the world into a more perfect place. So I think the advantages of scientific development outweigh the disadvantages. More?

Are there any shortcomings?

The disadvantages of scientific and technological development outweigh the advantages.

Now people's technology is more and more developed and their living standards are getting better and better. Although science and technology will bring convenience to people, it will also have an impact on people and bring great disasters to human beings and the natural environment. Technology will scar Mother Earth! So I think the disadvantages of technological development outweigh the advantages.

A few years ago, the forest resources of the earth were so rich that almost the whole earth was a tree except the ocean. That's a fairyland on earth! But now because of various life needs, such as making disposable chopsticks, making furniture, making paper and so on. Let people cut trees everywhere. Resulting in a substantial reduction in forest resources. Since 1980s, the global forest area has decreased by 1 1000 square kilometers every year, and desertification has affected 20% of the global land, and the atmospheric carbon dioxide concentration has doubled in 100. Due to the low forest coverage, a large number of wild animals have lost their living environment, and there are more than 4,000 endangered species in China! If this continues, the consequences will be unimaginable.

Sewage discharged from various factories is polluting water sources and threatening the lives of animals and human beings. China's per capita annual water resources are 2730 cubic meters, Canadian 12000 cubic meters and American 10000 cubic meters. Our water resources are less than those of other countries. Shouldn't we cherish water resources more than other countries? At present, China has 1. 700 million people drink polluted water because 36 billion cubic meters of sewage is discharged into rivers, lakes and seas every year, and 4/5 of them are untreated. This is the result of scientific and technological development!

……

The reduction of forest resources and water pollution ... these are the prices paid by people's scientific and technological development. If this goes on, the earth will be destroyed and mankind will be destroyed. Now, we should plant more trees to protect forest resources. Sewage should also be treated separately. So I think the disadvantages of technological development outweigh the advantages.

This morning, our class held a wonderful debate. The theme is: Do pupils do more harm than good or do more good than harm? On the positive side, it supports the view that the advantages of primary school students surfing the Internet outweigh the disadvantages. I support primary school students to surf the Internet, which does more harm than good, so I am the one who opposes it. I use my dumb tongue to become the one who opposes it. Want to know how wonderful this debate is? Then look down!

After class, I went back to the classroom, and the classroom was brand-new: nine eye-catching characters were written on the blackboard-"Debate on the pros and cons of surfing the Internet". There are colorful paintings and balloons next to them. The classroom is divided into two neat squares by desks and chairs. On the table in the first row of two squares, there are one, two, three and four positive independent variables and one, two, three and four negative independent variables in turn. Wow! This debate is unprecedented!

Ding rang and the debate began. The players of both sides have taken their positions. Our chairman, Mr. Li, explained the rules of this debate: this debate is divided into three stages: designated debate, free debate and final statement. Designated debate means that each student has to answer a question or a paragraph raised by the other party. The designated debate has begun. After arguing about Li Xiaoyi's greetings, I began to describe her point of view: the advantages outweigh the disadvantages, and talked about the advantages of surfing the Internet. As soon as she finished, I stood up at lightning speed, said hello, picked up my thick debate words, stated our views, and then refuted Li Xiaoyi and said, "After listening to my friends, it seems very imposing and reasonable. But please don't forget that today's debate is whether surfing the Internet is more beneficial than harmful or harmful than beneficial. Is a primary school student ... "Ha ha, my words hit the other key, I secretly pleased, just say that finish, Li Xiaoyi swallowed a mouthful. I think she must think she is wrong! I am even more ecstatic. Not only won a sigh of relief for the other side, but also the other "three generals" of the other side are not to be outdone. In the face of Shi Jiayang, who is eloquent, the opposing side argued, and Sun Jingyun made a witty remark, a paragraph and an example, which was easily settled; Li Jingyi, the opponent's three arguments, are well thought out. He read a passage slowly, and his opponent's friends were dumbfounded. There is also a string of Cao Qian's statistics. He has a glib tongue, which makes another debater full of praise. Wow! The three of them are really "female heroes"!

After the designated debate, it entered the white-hot stage of this debate-free debate. The free debate began, and I saw a green shadow-Wang-jumping out of the crowd in the square! He listed five advantages of surfing the Internet in a leisurely way. Hee hee, you can't beat me. There are many examples in my materials, and I am willing to accompany him to the end. As soon as he finished, I stood up, with a time difference of 0.5 seconds, and read the five disadvantages of surfing the Internet, which caught him off guard and left him speechless. Just when the members of the square were silent, an "emergency hero" Shi Jiayang suddenly appeared. He stood up angrily and asked us, "I guess the information of the other debater must have been checked online." Since surfing the internet is good for all of us, why does the other debater still think that surfing the internet does more harm than good? " Oh! This question has made my opponent argue that he doesn't know how to answer it! Just then, an "emergency heroine", Sun Jingyun, appeared in our team, only to see her raise her voice and say, "Yes, our information was searched online, but we don't think that surfing the Internet is bad, but the disadvantages outweigh the advantages!" Sun Jingyun's expression won applause from all the players on both sides. Then angry words. ...

Ding rang, the pros and cons made their final statements, and Miss Li announced the result of the draw. Everyone reluctantly left the classroom.

Although I am a little disappointed, this debate has given me great inspiration: as long as primary school students can make good use of the internet, the advantages outweigh the disadvantages, but if the attitude of surfing the internet is not correct, the advantages outweigh the disadvantages!
