三、还原信息
Communication（交流）has always been a necessary part of human life, allowing us to share information and express feelings. (1) In ancient times, humans used symbols and drawings on walls to tell stories and send messages. (2) As time went by, people developed languages and words that allowed more communication. The invention of paper and the pen made it easier for people to write letters to each other, even if they were far away. This method of communication was used for centuries.
However, the biggest changes came with the Industrial Revolution（工业革命）and later the technological development. The telegraph（电报）was invented in the 19th century. (3) This was followed by the telephone, which added the voice to long-distance（长距离的）communication, making it more personal and real-time.
The late 20th and early 21st centuries have seen the fastest development in communication. Social media（社交媒体）like WeChat have created new ways for us to share our lives and thoughts with more people. (4)
