In today's Chinese class, we had a heated debate: Is the development of science and technology beneficial or harmful? First of all, our host Mr. Wu delivered a speech: "As we all know, the development of science and technology has brought about great changes in our lives. However, these changes are not all in a good direction, and sometimes, the development of science and technology also brings new problems to mankind. For example, the invention of the automobile not only facilitates people to travel, but also brings environmental pollution problems; Air conditioning makes people warm in winter and cool in summer, but it reduces people's adaptability to the natural environment and reduces immunity; Computers can let us go to the world without going abroad, but because of computers and online games, some teenagers can't extricate themselves, neglect their studies and do nothing ... how to deal with such a problem? This time, we will debate about whether the development of science and technology is beneficial or harmful. First of all, please speak to the positive students. "

As soon as the teacher's words fell, several students raised their hands and kept shouting "me, me, me". The teacher called the best seat Mao Ruikai, and Mao Ruikai said fluently: "It is the development of science and technology that has promoted the progress of mankind, and it is the development of science and technology that has given mankind this brand-new and beautiful life. Throughout the ages, which dynasty and generation did not attach importance to the development of science and technology? Looking back, the four great inventions are unique; Look at the astronomical calendar and marvel; Look at Zhaozhou Arch Bridge, which is beautifully designed; A glimpse of the oriental masterpiece compendium of materia medica: look at the value of pi, seven decimal places; Overlooking the Silk Road and developing the economy; Blue and white porcelain is very famous overseas. Scientific and technological development is the road to a strong country and the first driving force for the progress of the Chinese nation. How can we live a happy life today without science? Without science and technology, how can we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can you eat hybrid 2? How can you put on cotton-padded clothes and live in a tall building? "

As soon as he sat down, several students across the street became unconvinced. Wan'er stood up and said eloquently, "That's true. However, as we all know, technology has also brought an impact on human health. Cell phone radiation makes many people suffer from diseases; Industrial wastewater pollutes the original clear rivers, making animals that used to rely on these rivers sick or even die after drinking these waters; Although air conditioning is warm in winter and cool in summer, the problem is serious. The appearance of air conditioning makes us in a comfortable environment all year round. Because of this, human's perception of natural temperature is getting weaker and weaker, so human can't adapt to the change of natural climate. And the gas emitted by air conditioners is the chief culprit in destroying the ozone layer! Isn't this the disadvantage brought by the development of science and technology? "

Wan'er answered Mao Ruikai like this. Then Yang Yiming retorted: "You said that the disadvantages of technological development outweigh the advantages. Can you come to class without a car, a gel pen, a ballpoint pen and a 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? "

Wan'er said quickly, "1, environmental pollution. This is the most direct and obvious disadvantage.

The extinction of species is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development. "

Wan'er sat down proudly, panting, and Yang Tianyu immediately said

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, and scientists have also developed solar-powered cars. Look at now, solar water heaters, solar air conditioners, solar cells ... environmental protection and energy-saving solar energy are gradually entering thousands of households. Isn't this the development of science and technology? "

Wan'er said quickly, "With mankind entering the 2 1 century, many amazing changes have taken place in the world. While rejoicing in the rapid development of science and technology, mankind has also experienced better uneasiness and even disaster. In addition to the panic caused by the development of high technology, especially biotechnology, war and disease seem to directly bring mankind to the door of hell. SARS, AIDS ..... 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. "

The teacher called Cai and He again, but their speeches were somewhat empty. Lu Jiaxin didn't say anything at all, so the teacher personally came out to help: "What Wan'er said is too ugly. Science and technology are developing and the times are progressing. These diseases have been solved by science and technology, and human beings have various effective solutions. "

Wan'er added: "Drugs can save lives, but they can also kill people. Many people invented poison by relying on high technology, which not only killed their own kind, but also killed many innocent people. Those people or children, flower of life has not had time to open, they will die early; As an adult, flower of life will take root prematurely when they can afford it; There are some old people whose flowers are drooping and dying, but those people still refuse to let them go and destroy their flowers with poison. This is the "result" of high technology, and this is the "benefit" of high technology.

The teacher supported Fang and said, "Wan'er, you have misunderstood. This is just that those who have evil thoughts use high technology to do bad things, and it has nothing to do with the disadvantages of technology. " Wan'er was determined to argue with Confucianism and retorted, "What about the nuclear explosion? The missiles launched by the United States in Hiroshima, Japan are still dangerous. "

......

Time slipped away unconsciously and the bell rang. The teacher said to those students who still have to refute, "well, it's getting late, class is over!" " "

A heated debate is over.
