In order to achieve a better life, we have also transformed nature and technology. The heavy labor force in ancient times was transformed by science and technology, mechanized and automated, which greatly improved work efficiency and economic development. Every invention and breakthrough in scientific research has formed our colorful material world today. Humans are using science and technology to pursue a better society and life.

As the saying goes, nothing is impossible except the unexpected.
In the past, it was difficult for people to get in touch with relatives and friends who were far away from home, and it was all by writing letters. However, this is no longer a problem today. Since the 20th century, with the rapid development of science and technology, especially computer network technology and electronic information technology, expensive luxuries such as mobile phones and computers have entered the homes of ordinary people and become necessities of our lives. The appearance of mobile phones has narrowed the distance between us, and the Internet, which came out in 1969 and has become popular all over the world, is more convenient, allowing you to sit in front of your computer at home and click the mouse, so that your friends who are far away can immediately receive your messages and reply to you, and enter the online world.
Be able to communicate openly with strangers online; You can express your opinions without fear; Feel free to express your feelings in Weibo or blog; You can get any information you want, such as news, knowledge and entertainment ... That's what the so-called "staying at home and knowing what's going on in the world" means. Let's imagine, if there is no mobile phone, how can we keep in touch with our relatives at will, understand each other's situation and enhance our feelings; If there is no internet, how can we chat with friends abroad, make new friends, get the knowledge we want and comment at will? This is the change of technology in our lives.
