As is depicted in the illustration, a boy holding a mobile phone in his hand is talking with the girl sitting beside him: "Why have you come to the library, all resources can be found online." This drawing demonstrate a phenomenon that numerous youngsters nowadays regard the internet as omnipotent. There is no denying that the rapid development of technology has provided us with easy access to rich resources. However, it also has countless drawbacks. Firstly, the great deal of misleading information found online will hinder us from finding truth and will affect our thoughts. Additionally, compared to reading books, people are more likely to be distracted by recreational content when scrolling through websites. As well as that, excessive reliance on online information will impair our thinking ability. (Why?) In conclusion, the internet is a double-edged sword. Living in an era of information, we should develop independent and critical thinking and not discard paper reading. In this way we will be able to tell the truth from fake news online and utilize the advantages of the internet to the utmost.
