Article 1: technology and life

With the rapid development of modern science and technology, we have stepped out of the previous era of eating raw food and drinking blood and come to an era of advanced technology. The development of science and technology has brought great convenience to our life.

I used to worry that there would be no lights at night, but every household is brightly lit tonight; It used to be luxurious to taste the delicious food in the sea, but now fish and shrimp are commonplace; In the past, I always found it difficult to deliver letters from home, but now, heaven is still our neighbor ... yes, a series of benefits brought by science can not be ignored!

In the Tang Dynasty, Yang Guifei wanted to eat fresh litchi, but fresh litchi could only be eaten in the south, so the emperor sent someone to transport it from thousands of miles away with a fast horse. How many fast horses have been exhausted to ensure freshness! But nowadays, it is common for ordinary people to eat fresh litchi everywhere in the market. It can be seen that the development of science and technology has brought us much convenience!

In ancient times, homeless people missed their relatives in their hometown very much because they lived and worked far away from their hometown for a long time. After writing home letters, their families didn't reply ... why? Because the letter may have been lost halfway before it was delivered home; It is also possible that it took a long time for the family to receive the letter, and it may take a month or two for the wanderer to receive the reply from the family. So it is difficult to say a word to his distant relatives.

Now, you can send messages to your family far away, which is very fast. In less than a second, the other person can know what you want to say, not only the conversation, but also the video chat. In this way, you can chat with distant relatives at any time and see what they look like. How happy it would be if you ever met your relatives in the distance! Technology can help you solve things that people can't. For example, if you encounter difficulties in learning, as long as you turn on the computer to type, the correct sentence will be displayed on the computer display screen. As long as there is science, there is no need to worry about any major difficulties.

However, with the development of science and technology, environmental problems have been ignored. Discharging wastewater into rivers on a large scale makes people unable to eat safe seafood and wastes valuable resources on a large scale, but never thought about how serious the consequences will be. While developing science and technology, we should also protect the environment.

Science and technology is a double-edged sword, which is the driving force of our human progress. It has brought us convenience and development, but it has also brought many negative effects. We should make full use of the benefits brought by science and technology, and we can't ignore the environment on which we live.

Article 2: Technology makes life better.

The land under our feet is undergoing earth-shaking changes all the time, all of which come from technology!

A thousand years ago, people lived a simple and hard life. At that time. People don't know what the spiritual world is. They just want to be safe, eat and drink, and maintain a normal life. To this end, people burn incense and worship Buddha and pray for peace. Carriage should be the only means of transportation, but it is very expensive, so people have to choose to walk. It takes a long time from Shanghai to Beijing. If you have pneumonia, there is no cure, so people's life span is very short.

Now someone has invented the mobile phone, which has eased the lovesickness and melancholy of people in different places; Someone invented the plane and gave up the long journey of people running around outside; Someone invented an anesthetic to prevent people with this disease from suffering another layer of pain. It is technology that makes our earth smaller and smaller. Now we are no longer satisfied with material enjoyment, but more spiritual comfort. Burning incense and worshipping Buddha still exists. What doesn't exist is people's stupid ideas.

The medical technology developed at present can cure almost all common diseases in life, and the extended people have more time to expand and enjoy life. The rapid development of natural science and technology such as biology and chemistry has brought rich and colorful spiritual food to people who were originally curious. While exploring and inventing, human beings affirmed their self-worth, and while enjoying the benefits brought by science and technology, they also gained happiness.

Once, people marveled at the stars all over the sky; Today, we have been able to send satellites into space.

Once, people were thinking about how to gain a foothold in this law of the jungle world; Nowadays, we are thinking about how to survive in this infighting world.

…………

In this society, we need to face up to the power of science and technology, so as to make our life better!

Article 4: Technology is with me.

The word technology is familiar to everyone. Simply put, technology is 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 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 rice with a rice cooker; Turn on the electric heater; The whole family is sitting around, enjoying the delicious food prepared by my mother with an electric wok ... Do you think we can leave technology anytime and anywhere?

Technology is very useful! For example, if there is no electric car, it will be inconvenient for us to communicate with distant relatives and friends; 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 go to Antarctica. Without space instruments, it would be just an illusion for humans to land on the moon. ...

On the contrary, with technology, our life will be better-with fax, our documents can be easily sent out in an instant! With robots, you can be in a space that people can't reach; Using laser, you can make fitness equipment; With air conditioning, people can feel as comfortable as spring even in hot summer. ...

It is not difficult to see: all this, people enjoy the achievements of science and technology!

This shows that technology has helped us create a superior living environment; Science and technology have improved our quality of life; Technology is the crystallization of the wisdom of people all over the world!

We are engaged in technology, and we should constantly learn new technologies!

Science and technology are around us, and we must vigorously develop science and technology!
