With the passage of time, the rapid development of the motherland, many things are developing rapidly, and our lives are becoming more and more abundant, but if there is anything that has changed our lives, I think I have to say that science and technology, in today's life, technology is always everywhere, technology is around me.

Walking on the road at night, there are electric lights to illuminate us; Call a friend, and you can take out your mobile phone at will; When I get home, I turn on the TV to watch the news, turn on the computer, and chat with friends; Mom steamed the rice in a rice cooker; Turn on the electric heater; The family sat around and admired the delicious meal that Mom had prepared in an electric wok......You see, anytime, anywhere, can we leave technology?

The usefulness of technology is so great! For example, if we don't have an electric car, we can't socialize with distant friends and family; If there is no EMU, it is difficult for people to travel to various places; Without the Space Shuttle, it would be an empty phrase for people to go into space; Without icebreakers, it would be difficult for us to go to Antarctica; Without spacecraft, landing on the moon would be nothing more than a fantasy ......

On the contrary, with technology, our lives will be much better – with faxes, our documents can be easily sent out in an instant! With robots, it can be in spaces that are difficult for people to reach; Using lasers, fitness equipment can be made; With air conditioning, even on a hot summer day, people can be as comfortable as spring ......

Science and technology not only make our lives better, but also a sign of our social progress, science and technology are all around me, we should also work harder to learn, and strive to make our own contribution to the development of science and technology.

The composition is as follows:

Mom and Dad went out to work, and grandparents didn't want to be idle, so they opened a commissary at the entrance of a kindergarten.

In the first few days, the commissary business was very hot, it was called a boom, and grandma and grandpa often had a smile on their faces, which affected everyone in the family, so everyone in our family was very happy in those days, and the atmosphere at home was much more relaxed.

However, there are unforeseen circumstances in the sky, and people have good and bad luck. The commissary's business didn't stay booming. Soon after, the grandparents received the fake money, and although they didn't want to believe it, the truth was in front of them: it was fake money.

After the incident, my mother immediately went to the Internet to buy a money detector and taught them how to use it, but no matter how much prevention is prevented, some people with ulterior motives can't be prevented.

One afternoon, a man riding an electric car bought two packs of cigarettes and gave his grandfather 50 yuan, and the grandfather told them not to leave first, and then turned around to get the money detector, and the man noticed that something was wrong, quickly picked up the cigarette and ran. In the days that followed, the nagging grandmother began to become reticent, and the grandfather often wandered around the house, one cigarette after another.

Grandparents often say: "Life is getting better and better now, and it is becoming more and more convenient. ”

Mom also quipped: "Isn't that the development of science and technology that makes life very convenient now?" "Mom's joke made us smile.

Mom is right, today's technology makes people's lives more convenient, but aren't all these changes brought about by technology?
