what changes have the development of science and technology brought to our lives? Please come with me and have a look!

the progress of science and technology has made our learning environment more superior. Mom said that the previous school was made of mud and tiles. There was no fan, no air conditioning, no TV teaching, and no computer courseware. Students could only attend classes in classrooms that were hot in summer and cold in winter. Teachers only used a blackboard that could not be wiped clean. Unlike us now, sitting in a spacious and bright classroom, listening to the teacher's explanation, watching TV and computer courseware, learning can be exciting.

The progress of science and technology makes the work of uncles and aunts safer and more efficient. Grandma said that in the past, plowing depended entirely on people digging with hoes, and farmers' uncles could only live a life of sunrise and sunset every day. Workers' uncles had to do their own work to carry heavy goods and do dangerous work. Now, the farmer's uncle has a farming machine, and a person can do a lot of farm work in one day by operating a machine, and they can enjoy themselves in the rest of the time. With the help of robots, workers' uncles are more efficient and no longer have to do those dangerous things themselves.

The progress of science and technology has not only brought about earth-shaking changes in our study, work and life, but also greatly improved our daily life.

It makes us dress more comfortably and beautifully. From the previous cloth clothes and cotton-padded jacket to the present sweaters, silk skirts and down jackets; From the previous manual sewing to the present mass production by machines, the materials and styles of clothes are varied and varied. It also makes us eat richer and more delicious. In the past, people could only eat food at that time and in season, but now we can eat food from all over the world that is out of season at any time. And with the help of rice cookers, pressure cookers, electric ovens and so on, the food is more delicious.

the progress of science and technology also makes our travel more convenient and faster. In the past, people had to travel a long way to get on trains and buses. Now, not only the urban transportation is convenient, but even the rural areas have access to highways. High-speed trains and airplanes let us go wherever we want.

there are countless changes brought about by scientific and technological progress! Our grandparents and fathers used their hard work and wisdom to make great progress in science and technology and make our lives change with each passing day, but they also left us with many problems, such as: cars can't avoid rollover, planes still crash, robots can't completely replace people's work and so on.

Therefore, we must be brave in pioneering and innovating, so as to make our motherland more prosperous and let people enjoy more benefits brought by scientific and technological progress.

Science and technology are constantly changing our world, making our life colorful, interesting and convenient.

"is like a spring gale, come up in the night, blowing open the petals of ten thousand pear trees." In the past two hundred years, science and technology have developed rapidly. From kerosene lamps used in Ming and Qing dynasties to energy-saving lamps used today; Wired telephone reporting from the radio at the beginning of the nineteenth century to the end of the nineteenth century; From the "Eniac" computer born in the University of Pennsylvania in the mid-21th century to today's multimedia computer; From the "mobile phone" used at the end of the twentieth century to the current 4G network. Because of science and technology, our world has undergone earth-shaking changes, but also changed our lives.

so what will the future world be like?

the 21st century will be an era of biotechnology. In the future, progress will be made in organic acid and other fermented products, the development of biological nitrogen fixation and protein project, biological pesticides, artificial intelligence, human genome project, pollution control and other aspects, and it will gradually develop into a cross-disciplinary biotechnology era.

the 21st century will be the era of intelligent transportation. With the increase of cars, traffic accidents, traffic jams and waste gas pollution have become more and more serious problems. Therefore, firstly, the road traffic can be managed by railway (line), thus greatly improving the safety of driving and the utilization rate of roads. The main advantages are: firstly, improving the safety of automobiles and implementing automatic control; secondly, implementing intelligent control of traffic, such as automatic payment; The third is to provide the best driving route for ground driving through satellite positioning system.

the 21st century is the nano age. Nanotechnology is the technology of products with nanometer (1 nanometer equals one billionth of a meter) as the unit of length. The micromechanics made are very small, such as the smallest electromagnetic motor at present, with a weight of only 4 mg, a diameter of 8 mm, a rotating speed of 1,111 revolutions per minute and a working voltage of 1.7 volts. Nano-technology will be applied to various fields of human beings, which can eliminate faults in dangerous environments, can be used for automatic adjustment of household appliances, and can act as a doctor to enter human medicine to treat diseases.

this is our technology, and this is our future world. I believe that with the continuous progress of science and technology, more products and technologies will become a reality.

1 "Mao", the time box took me to the future science and technology museum.

when you enter the gate of the Science and Technology Museum, the first thing you see is a fountain using solar LED lights, which uses a circulating water system and is environmentally friendly. Bypass the fountain pool and come to the selection area. * * * has 25 entrances, and the service facilities at the entrance are all available. Visitors should first choose different channels to enter. If minors want to pass through the red entrance, while adults enter the blue entrance, and the elderly are inconvenient to move, they will enter the barrier-free green entrance.

after that, the tourists will take a time machine with the speed of 8,111 kilometers per hour to their own museum. The first area is the animal park, where there are mainly some animal exhibitions and animal experience machines. For example, the dinosaur survival experience simulates the survival process of dinosaurs. In addition to these, there is also a signature project in the animal park, which is "Exploring Amazon". Passengers enter just visiting on an adventure car, surrounded by running elephants, lions and animals in the tropical rain forest. Everything is made of 4D technology, which is very realistic, accompanied by the sound of animals and the swinging of seats back and forth, giving tourists a real adventure.

After the trip to the animal park, we came to the plant kingdom. Here, you can not only visit the flower exhibition, appreciate the plants, but also consult the information about plants, cultivate the seeds of your favorite plants and plant them. These interesting activities will make tourists gain knowledge through joyful experiences and attempts. As soon as I entered the door, the smell of gardenia rose to the nose, but it was not the smell of real flowers, but was transformed from the unique ingredients secreted by pollen. In the plant paradise, these humanized designs are everywhere, creating a warm atmosphere.

The third part is the future world. In this area, it is mainly about the display of science and technology, future exploration and the mystery of the universe. One of the most interesting is the "simulated spaceship cabin". Here, you can become an astronaut, try on a spacesuit and experience the feeling of weightlessness in space. You can even "challenge the ring" to win the travel package of Mars, Venus, Saturn and Jupiter, and further feel the mystery of the universe. In addition to the "Mystery of the Universe", in this unit of the Future World, you will also see new scientific and technological products displayed, among which robots will invite you to their Party in the future house to experience more convenience and quickness brought by science and technology.

this is the science and technology museum in my mind. Let science, the golden key, lead us to the magical future!

everyone is familiar with the word science and technology. Simply put, science and technology is science and technology. In a broad sense, it refers to the sum of natural science and technology and social science and technology.

since the reform and opening up, with the passage of time, science and technology have mushroomed and are developing rapidly in the motherland. Looking around life, technology is everywhere, and technology is by my side!

Walking on the road at night, there are electric lights to illuminate us; Call a friend and take out your mobile phone at your fingertips; Back home, turn on the TV to watch the news, turn on the computer, and chat with friends; Mother steamed the rice with a rice cooker; Turn on the electric heater; The whole family sat around and enjoyed the delicious food prepared by my mother with an electric frying pan ... You see, can we leave technology anytime, anywhere?

the use of technology is great! For example, if there is no electric car, it will be inconvenient for us to communicate with friends and relatives far away; If there is no EMU, it will be difficult for people to travel everywhere. Without the space shuttle, it would be empty talk for people to go into space; If there were no icebreakers, it would be difficult for us to visit Antarctica. Without space instruments, people landing on the moon will only be an illusion ...

On the contrary, with technology, our life will be better-with fax, our documents can be easily transmitted instantly! With a robot, it can be in a space that people can't reach; Using laser, you can make fitness equipment; With air conditioning, even in hot summer, people can feel comfortable as spring ... < P > It's not hard to see that people enjoy all these achievements of science and technology!

It can be seen that technology has helped us create a superior living environment; Science and technology have improved our quality of life; Technology is the crystallization of people's wisdom all over the world!

We are in technology, so we should keep learning new technologies!

technology is around us, and we should vigorously develop it!

On this day, I took my latest invention "supersonic plane" to visit my primary school teacher for 21 years. I was really ashamed that I couldn't visit my teacher for this supersonic plane. Think about how much effort the teacher has devoted to our future! I think the teacher must be much older after 21 years. At that time, the young teacher must be a white-haired grandmother now, I guess.

A voice woke me up from my guess. I saw that it was a "super water". Lu. Empty. Airplane ",although my supersonic plane is also water." Lu. Empty. Aircraft, but the system settings of my aircraft are very different from those of its aircraft! This plane was invented by my primary school classmate Zheng Yongyong. Isn't he in America? Why are you back?

when I came to the teacher's door, I saw that the teacher was still gorgeous and moving, and I didn't see the demeanor of a white-haired grandmother at all. I asked Zheng Yongyong what was going on, but he also said that he didn't know. We both puzzled the teacher, and the teacher said that it was the youth-unchanging medicine invented by our primary school classmate Zheng Lin: "It is a magic medicine that can keep young forever after being put on. Because, during the most experimental period in Zheng Lin, the teacher once became the most right-hand man in Zheng Lin, so Zheng Lin invented the youth-unchanging medicine and used it on the teacher for the first time, so the teacher gained eternal youth. We said, "We can become a new generation of talents, but it was not given to us by the teacher. At this time, the teacher's excited tears trickled down, and we also cried excitedly. After we stopped crying, we took the overspeed elevator to the 54th floor" Teacher's Home ".

When we got to the teacher's house, we saw Zheng Lin, who was studying the lie detector. We talked with Zheng Lin for a while, then stayed at the teacher's house for a while and then went back to study things. "

think about it, how advanced science and technology are now! But we should do better!
