Writing prompt: The Internet Has Changed Our Life

Student essay:
A long time ago, there were no computers, so as the Internet. But as the computers had invented, Internet is more essential for our life at present.
Before the Internet invented, our life is less boring and common than nowadays, because people had nothing interesting to do except watching TV, listening to the music, reading books and so on.
After the Internet invents, a tremendous amount of people buy computers, so that they can surf the Internet. It has brought both convenience and knowledge to us which makes our life better and better. Nonetheless, it is unfavorable for young people to surf the Internet for too much time, because it does harm to their eyes.
In my opinion, Internet is not only for fun, it also enriches people's knowledge and experience. As long as not to indulge in amusement, Internet is also a useful tool which can help us a lot.
Maybe in the future, Internet will be more and more popular among the youngs and the olds.

error_description: ① Conjunction Error: The original 『so as』 cannot correctly connect two negative clauses. According to English grammar rules, the conjunction of negative clauses requires 『nor』. Therefore, the incorrect conjunction 『so as』 is corrected to 『nor』 to meet the requirements of a negative parallel structure.; ② Sentence Structure Error: According to English sentence composition rules, the original sentence lacks grammatical components. The corrected 『nor was there』 structure is complete and conforms to English inversion rules (when a negative word is at the beginning of a sentence, an "auxiliary verb + subject" inversion structure is required). The final sentence is adjusted to: 『A long time ago, there were no computers, nor was there the Internet.』.
