2. Secondly, the development of science and technology makes the transmission of information faster and faster. In ancient times, the imperial court issued an order, and local officials had to wait for a long time to receive the order. In war, information could only be transmitted through wolf smoke and post stations, which was extremely inefficient. Now it is different. The emergence of high-tech tools such as mobile phones, television and radio made the transmission of information extremely convenient and simple. We can know the major events on the earth by watching TV at home. As soon as the new laws and regulations of the central government are promulgated, people will soon know that one message from home is worth a ton of gold is no longer needed. We can contact our family members through mobile phones and telephones, and even some videophones can see their voices and faces to comfort our lovesickness.
3. In addition, the development of science and technology has promoted people's physical and mental health development and prolonged people's life span. In ancient times, smallpox was almost a terminal disease, like a plague, and even a cold almost killed people. In ancient times, people who could live to 6 years old were called longevity. Now, with the development of science and technology, smallpox has become a very common disease, which is easy to treat. Now people's average life span can reach 72 years old, and medical care is provided. Most of the diseases can be cured, so that many families can avoid the pain of losing their loved ones, and more people can enjoy their lives better
4. Of course, there are many benefits brought by the development of science and technology. Without the development of science and technology, our life is unimaginable. Our life is dark. It is the development of science and technology that has saved us and science that has saved us from the hot age of water.
