In hot summer, just after work, we can turn on the air conditioner at home and adjust it to the right temperature through our mobile phone. If there are pets at home, we can also check the pet's condition through monitoring, and whether we have been squatting at home waiting for the owner to come back. The lights that are already on when lonely people come home are also the warmth brought by technology. The intelligent sweeping robot always cleans the ground cleanly, and the changed dirty clothes can be put into the automatic washing machine and taken out at the set time. The kitchen is smoke-free, always bright and beautiful, and eating is also very appetizing. The smart bracelet you wear can remind yourself to remember exercise, record your physical condition in time and adjust your exercise plan. These are all things that can be done by the existing level of science and technology. Building a smart home through smart devices, technology has brought endless convenience to our lives.

2. Distance is no longer a problem.

Without shops, shopping is easier and faster. China leads the world in shopping, mobile payment, e-shopping and developed logistics. The development distance of transportation technology is no longer a problem. Our high-speed rail technology ranks first in the world, which is easy, safe and comfortable. In the past, once relatives were far apart, it was difficult to meet again, or it took a long time to meet. Now even the sense of distance brought by going abroad has been greatly weakened by the development of science and technology.

3. Innovation of learning style

There are all kinds of electronic devices, and tablet computers even replace textbooks, thus realizing paperless learning. The development of network technology has connected people all over the world. In the past, people closed their eyes and the news didn't circulate. Now all we have to do is turn on the phone and check the computer, so we can know any news. We can also get the learning materials we need through the Internet. There are also various ways of interaction in the classroom. In the past, teachers could only give lectures to textbooks and blackboards, but now the combination of audio and video and ppt is more diverse and vivid.

It can be said that the development of science and technology has brought earth-shaking changes to our lives. Our comfortable and convenient life now cannot be separated from the hard work of scientific researchers. In the future, our life will be more exciting because of technology.
