The Impact of Technology on Teenagers
With the rapid development of technology, smartphones and social media have become an inseparable part of teenagers' lives. While these tools provide us with convenient access to information and instant communication, they also bring challenges that cannot be ignored.

On the one hand, technology has revolutionized learning. Through educational apps like Khan Academy, students can watch instructional videos anytime, anywhere. Online platforms even allow us to attend virtual classes with international teachers. However, excessive screen time may lead to health issues. Many teenagers suffer from eye strain due to staring at screens for hours, and lack of physical exercise often results in obesity.

What worries parents most is the addiction to social media. A recent survey shows that 68% of teens check their notifications within 5 minutes of waking up. The constant need to compare oneself with others' "perfect" online personas may cause anxiety or low self-esteem. Nevertheless, if used wisely, technology can enhance creativity. For example, some classmates of mine design digital art using graphic tablets, while others code simple games through programming courses.

In conclusion, technology itself is neither good nor bad. It is how we utilize it that determines its value. Setting time limits and focusing on meaningful activities could help us become masters rather than slaves of technology.

教学建议：

1. 议论文框架训练：用"PEEL"结构训练段落写作（Point观点 - Explain解释 - Evidence证据 - Link总结）

2. 同义替换练习：将简单词升级为学术词汇（如把"use"改为"utilize"，"problem"改为"issue"）

3. 改错练习：故意在范文中加入语法错误（时态错误、主谓不一致等），让学生纠正

4. 话题迁移：用相同结构讨论其他现象（如网络游戏、AI人工智能等）
