Does science and technology make the world bigger or smaller (the topic of junior high school students' debate should be positive and negative)

1 The North American city of Montreal is famous for its successful use of urban underground space. It claims to own the largest underground city in the world. Here, countless passages extending from subway stations connect subways, suburban railways, bus lines, underground walkways and a large number of mixed development zones into a huge network. According to statistics, more than 60 conjoined buildings have a total construction area of 3.6 million square meters. Nearly 2000 shops and entertainment places are also integrated in this way.

This includes small shops, big department stores, restaurants, cinemas, theaters, exhibition halls and so on. More than half a million people circulate in this underground network every day.

With the development of science and technology, people can send spacecraft into space one day, broaden people's horizons and even emigrate to space. It is with the help of science and technology that we human beings can jump out of the circle that originally bound us and explore a wider world. For example: The first astronaut to go into space: yuri gagarin, 196 12 April 12, he took off in the former Soviet spaceship 1, which represented the first time for human beings to go into space.

With the help of science and technology, we can know the world well and everything about it. We often say, "It's better to go to Wan Li Road than to study in thousands of books". Now at home, we don't need to study in thousands of books or go to Wan Li Road. As long as we search online, we can get relevant information in a centralized and efficient way, which will make our knowledge world broader. Isn't this the help of technology?

With the development of science and technology, with trains, planes, ships, subways and cars, all convenient means of transportation enable us to travel quickly and have fun. If we still use these primitive modes of transportation, such as walking or cycling, we will spend a lot of time on the road, and some distant places are simply inaccessible. Subjectively speaking, the world we know has become bigger because of the convenience of science and technology.

Since we entered the information age, our circle of friends has expanded a lot. In ancient times, many relatives and friends who were good friends had to have a vague understanding of each other's living conditions because they were far apart and had difficulty in correspondence, so they could not communicate easily and quickly. With the telephone network, we can communicate with distant relatives and friends, convey our feelings and living conditions in time, and our social world of making friends has expanded.

Science and technology enable us to discover bigger and farther things. Since then, human beings have set their sights far and devoted themselves to areas full of risks that they have never set foot in before. With a camera, your visual distance extends from the South Pole to the North Pole, which makes us feel that the original distant place is not far away, and technology has expanded the world we can know.
