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.
Chapter 2: Technology adds color to life.
The arrival of 2 1 century brings people a surprise-advanced technology. In recent years, "technology" is getting higher and higher, and people's lives have gradually become more convenient and affluent with technology.
Developed technology occupies my whole modern happy life and is updated every day. Television, computers, refrigerators, mobile phones ... all came out in this golden age.
Computers are the most brilliant, dazzling and popular among these science and technology stars. He is becoming more and more advanced and popular, even primary school students can't live without him. It has countless uses. You can use it to play games when you are bored, which brings joy to people. The computer has changed from black and white to color. The computer can help me look up information, practice typing and make slides, just like my best friend in my life. The teacher assigns a composition every week, and almost every time I have no class to write. I used to be in a hurry, or I couldn't find satisfactory information after tossing and turning, which was extremely troublesome. But it's different now. You can easily find the answer by typing the required classes on the computer. Computer is an indispensable thing for students to study. Computers can express sincere wishes to people during festivals. E-mail during the Spring Festival can enhance the friendship and relationship between friends, and promote family relations and happy family life. Pictures on the Internet can send good wishes to people.
There used to be only a dozen TV stations, but now there are hundreds of TV stations, which really makes people dumbfounded! The TV is not as thick as it used to be. Now there is a night crystal TV, which is not troublesome to use. There will be 3D TV in the future, so you can enjoy that happy time without going to the scene!
After I bought food before, I became moldy after a few days. Since I have a refrigerator, the food can be kept fresh and the nutrition of the food has not been lost. A family can live a happy and beautiful life.
If there are no mobile phones, people will still be in trouble. With mobile phones, the distance between people is closer and people's friends are increasing day by day.
It can be said that technology has made my life happy and convenient!
