Connected but Free
The internet has changed our lives in amazing ways. News travels across the world in seconds, and friends on different continents can chat as if they were in the same room. However, the same technology that brings us together can also take us away from the real world, which worries many parents and teachers. The key, as Cozy often says, is to use it wisely rather than let it use us.
互联网以惊人的方式改变了我们的生活。新闻在几秒内传遍世界，不同大洲的朋友可以像在同一个房间里一样聊天。然而，把我们聚在一起的同一项技术，也可能把我们带离现实世界，这令许多家长和老师担忧。正如 Cozy 常说的，关键在于明智地使用它，而不是让它使用我们。
Han Mei is a good example of smart use. Last year she downloaded a language-learning application, which offers short video lessons in a series of levels. Every morning she spends twenty minutes on her phone, practicing listening and pronunciation. 'The app is convenient because I can study anywhere,' she said. 'But I make a rule for myself: no chatting during study time.' Thanks to the app, her English has improved a lot, which surprised even her teacher.
韩梅是明智使用的典范。去年她下载了一个语言学习应用，这个应用按系列分级提供短视频课程。每天早上她在手机上花二十分钟练习听力和发音。“这个应用很方便，因为我在任何地方都能学习，”她说，“但我给自己定了一条规矩：学习时间不聊天。”多亏了这个应用，她的英语进步很大，连老师都感到惊讶。
Jack, on the other hand, is a young blogger, whose articles about online life have thousands of readers. He interviews programmers and designers, asking them about the internet industry and its future. 'People who work online must be professional and responsible,' he wrote in one post. Jack's blog, which is updated every Friday, has become a small classroom for his classmates, who discuss his ideas in the school computer club.
另一方面，杰克是一位年轻博主，他关于网络生活的文章有成千上万的读者。他采访程序员和设计师，询问他们关于互联网行业及其未来的看法。“在网上工作的人必须专业而负责，”他在一篇文章中写道。杰克的博客每周五更新，已成为同学们的小课堂，他们在学校电脑俱乐部里讨论他的观点。
But the internet also has a dark side. Some students become addicts, spending hours on games or social media until midnight. They lose focus in class and their grades drop, which makes them feel anxious. One day Cozy asked his class to list the risks of online life. 'Addiction, false information and wasted time,' the students answered. Then he taught them a simple method: set specific goals, use a schedule, and turn off the phone when studying.
但互联网也有黑暗的一面。一些学生成了网瘾者，玩游戏或刷社交媒体直到深夜。他们在课堂上无法集中注意力，成绩下降，这让他们感到焦虑。一天，Cozy 让全班列举网络生活的风险。“网瘾、虚假信息和浪费时间，”学生们回答。然后他教给他们一个简单的方法：设定具体目标，制定时间表，学习时关掉手机。
At the end of the semester, Han Mei and Jack gave a joint speech, which moved the whole school. 'The internet is a window, not a cage,' Han Mei said. 'We should acquire knowledge from it, share kindness through it, and always keep our feet on the ground.' Their speech, as everyone agreed, was the best advice of the year. The students left the hall with a new idea in mind: be connected, but stay free.
学期末，韩梅和杰克做了一场联合演讲，感动了全校。“互联网是一扇窗，而不是一个笼子，”韩梅说，“我们应该从中获取知识，通过它传递善意，并且永远脚踏实地。”大家都认为，他们的演讲是今年最好的建议。学生们带着一个新的想法离开大厅：保持互联，但保持自由。

3语法小课堂：非限制性定语从句
which / who 引导的非限制性定语从句
先行词，+ which / who + 从句
用逗号与主句隔开，去掉后主句意思仍完整：My blog, which is updated every Friday, has many readers. （我的博客每周五更新，有很多读者。）
which 可指代前面整个句子：He passed the exam, which made his parents happy. （他通过了考试，这让父母很高兴。）
who 指人：Jack, who plays the guitar, is my best friend. （杰克会弹吉他，是我最好的朋友。）
⚠️ 非限制性定语从句不能用 that 引导，关系词也不能省略。
as 引导的非限制性定语从句
as + 从句（可置于句首或句尾）
as 指代整个主句，意为正如：As everyone knows, the internet is powerful. （众所周知，互联网很强大。）
常见搭配：as is known / as we all know / as is often the case。
which 从句只能后置，as 从句可放句首。
⚠️ 位置区别：which 引导的只能放在主句后；as 引导的位置灵活，常在句首。
👨🏫Cozy 老师说：高中语法重在「在语境中理解」——多读课文里的例句，语法自然就活了。
