The internet effects on teenagers the internet has both positive and negative effects on teenager's lives. On the positive side, IT helps us develop our interests. For example, I love reading science fiction novels, and I post my book reviews online. Every time I write a review, I get hundreds of comments. Also, IT allows us to learn online. Last month, I took an online coding course and learned a lot of useful skills. However, there are negative effects too. Some teenagers spend too much time on social media. My cousin, for instance, spends more than five hours a day throwing through social media apps, which makes them have little time for homework. What's more, the internet may expose us to inappropriate content. Once, my little sister saw a scary video by accident when he was using the internet, and he was afraid to sleep alone that night. In conclusion, while the internet is helpful, we should use IT properly. 上 Unit 3 Our digital lives （沪教2025版）八年级 Writing Learning objectives 0 Lead in Pre-writing 2 While-writing Post-writing 4 Deepthinking Summary 6 Assessment 1 3 5 7 Homework 8 By the end of the lesson, I will be able to... 1 2 3 master vocabulary and expressions related to the internet's effects； write a paragraph to express opinions about the internet's positive and negative effects, supporting ideas with examples； have a comprehensive understanding of the internet and use it properly. 00 Learning objectives https://www.21cnjy.com二一教育 www.21cnjy.com Lead in 01 https://www.21cnjy.com二一教育 What do you usually do on the internet?
