科技与生活：手机与网络的影响（一）
Nowadays, mobile phones are very popular among students. Many of us use phones to talk with friends, play games or watch videos. On one hand, phones help us learn new things. We can search for information and study online. On the other hand, some students spend too much time on the phone. They don’t do homework or go to bed late. This is not healthy.
Now, I think we should use phones in a smart way. We can use them to help with study, but we should not play games all night. It’s important to balance study and rest.
如今，手机在学生中非常流行。我们很多人用手机和朋友聊天、玩游戏或看视频。一方面，手机帮助我们学习新知识，我们可以搜索信息并在线学习。另一方面，一些学生在手机上花费太多时间，不做作业或熬夜，这对健康不利。
现在我认为我们应该聪明地使用手机。我们可以用它来辅助学习，但不应该整晚玩游戏。平衡学习和休息很重要。
✍️点评与重点：本文结构清晰，使用了“on one hand... on the other hand”表达对比观点，适合初中生模仿。关键词如“popular”“search for information”“balance”都是中考常考词汇，建议背诵积累。
科技与生活：手机与网络的影响（二）
The Internet is an important part of our life. We use it to study, communicate and have fun. For example, I often use the Internet to do homework and read English stories. It helps me improve my English skills.
However, the Internet also has some problems. Some students spend too much time playing online games. They forget to eat or sleep. Also, not all information online is true. We must learn to tell good from bad.
In my opinion, we should use the Internet wisely. It is a useful tool, but we must not depend on it too much.
互联网是我们生活中重要的一部分。我们用它来学习、交流和娱乐。例如，我经常用网络做作业和阅读英语故事，这帮助我提高了英语水平。
然而，网络也有一些问题。一些学生花太多时间玩网络游戏，忘记吃饭或睡觉。此外，并非所有网络信息都是真实的。我们必须学会分辨好坏。
在我看来，我们应该明智地使用互联网。它是一个有用的工具，但我们不能过度依赖它。
✍️点评与重点：使用了“for example”引出具体事例，增强说服力。“improve my English skills”“depend on it too much”是实用表达。文中“not all...”句型展示了部分否定，语法点值得掌握。
科技与生活：手机与网络的影响（三）
Mobile phones and the Internet have changed our life a lot. We can talk to people far away, watch movies and buy things online. Life is much more convenient now.
But there are also bad sides. Some students become addicted to phones. They feel unhappy when they can’t use them. Also, spending too much time online can make us less active. We don’t exercise or talk with family.
I think we should set rules for phone use. For example, no phones during meals or before sleep. In this way, we can enjoy technology without losing real-life happiness.
手机和网络极大地改变了我们的生活。我们可以和远方的人通话、看电影、在线购物，现在的生活方便多了。
但也存在负面影响。一些学生对手机上瘾，无法使用时会感到不开心。此外，上网时间过长会让我们变得不活跃，缺乏锻炼，也不和家人交流。
我认为我们应该为使用手机制定规则。例如，吃饭或睡觉前不使用手机。这样，我们既能享受科技，又不会失去现实生活中的快乐。
✍️点评与重点：使用“have changed our life”体现现在完成时的实际应用。“addicted to”“set rules”是表达习惯管理的高分短语。结尾提出具体建议，使文章更具建设性，适合考试写作提分。
