It allows us to study online, communicate with others, and access the latest information. However, every coin has two sides. Excessive screen time may lead to poor eyesight, sleep problems, and even Internet addiction. Moreover, cyberbullying and misinformation are also serious issues. Therefore, I suggest that we set limits on our daily Internet use, focus on valuable content, and never disclose personal information online. Let’s develop self-discipline and use the Internet as a tool for learning and connection rather than a source of distraction. In conclusion, let’s work together to create a healthy and positive online environment. Thank you! 第四步：连句成篇 . Good morning, respected teachers and fellow students. Today, I stand here to address a crucial topic: the rational use of the Internet. ①With digital devices becoming increasingly prevalent in our daily lives, mastering this skill is more important than ever. The Internet, if used wisely, is a powerful tool for learning and global connection. Searching for information online, we can access vast knowledge; communicating with people worldwide, we broaden our horizons. However, mind endlessly scrolling through short videos, many students find their concentration spans shortened, and their study time wasted. ②Only when we exercise strict self-discipline can we truly take advantage of the power of this double-edged sword. Therefore, I propose we become masters, not slaves, of technology. Our phones put away during study hours, let's prioritize real-world interactions and deep learning. Remember, the Internet is a good servant but a bad master. Let's use it rationally to build a brighter future! Thank you. 升级高分版本 . 【高分词汇】 ① broaden our horizons（开阔视野） ② double-edged sword（双刃剑） 【高分句型】 1.
