手机对青少年的影响：利与弊分析（范文一）
Nowadays, mobile phones are very popular among teenagers. Many students have their own phones. Some people think mobile phones help teenagers a lot, but others worry about their bad effects.
On the one hand, mobile phones are useful. Students can use them to search for information, learn new things, and talk with family. For example, they can watch English videos or listen to online lessons. This helps them study better.
On the other hand, mobile phones can also cause problems. Some students spend too much time playing games or using social media. They don’t do homework or sleep well. This is bad for their health and study.
In my opinion, mobile phones are good tools, but we must use them wisely. Students should not use phones too much during study time. Parents and teachers should help them build good habits.
如今，手机在青少年中非常流行。许多学生都有自己的手机。一些人认为手机对青少年帮助很大，但另一些人则担心它带来的负面影响。
一方面，手机很有用。学生可以用它来查找信息、学习新知识、与家人联系。例如，他们可以看英语视频或听在线课程，这有助于他们更好地学习。
另一方面，手机也会带来问题。一些学生花太多时间玩游戏或使用社交媒体。他们不做作业，睡眠也不好。这对他们的健康和学习都不利。
在我看来，手机是很好的工具，但我们必须明智地使用。学生在学习时间不应过多使用手机。家长和老师应帮助他们养成良好的习惯。
✍️点评与重点：
- 结构清晰：采用“引言—正反观点—个人观点”的议论文结构，适合初中写作。
- 关键词汇：popular, search for information, social media, use wisely 等为高频写作词汇，建议掌握。
- 句型亮点：“On the one hand... On the other hand...” 是表达对比的经典句型，适合用于议论文。
手机是否应该被允许带入校园？（范文二）
Should students be allowed to bring mobile phones to school? This is a hot topic today. I believe students should not bring phones to school.
First, mobile phones can distract students. When they have phones, they may check messages, play games, or watch videos in class. This makes it hard to focus on lessons.
Second, some students may use phones to cheat in exams. They can search answers or send messages to friends. This is not fair to others.
Also, not all students have the same kind of phone. This may cause jealousy or bullying. Some may feel bad if their phone is old or cheap.
Of course, phones are useful in emergencies. But schools can provide landlines or help from teachers. In short, the disadvantages are greater than the advantages.
学生应该被允许带手机上学吗？这是当今一个热门话题。我认为学生不应该带手机上学。
首先，手机会分散学生的注意力。当他们有手机时，可能会在课堂上查看消息、玩游戏或看视频，这让他们难以集中精力听课。
其次，一些学生可能用手机在考试中作弊。他们可以搜索答案或给朋友发消息，这对其他人不公平。
此外，并非所有学生都有相同类型的手机。这可能导致嫉妒或欺凌。如果他们的手机老旧或便宜，一些学生可能会感到自卑。
当然，在紧急情况下手机很有用。但学校可以提供座机或老师帮助。总之，弊端大于好处。
✍️点评与重点：
- 论点明确：开篇直接表明立场，符合议论文写作要求。
- 逻辑递进：从“注意力分散”到“作弊”再到“心理影响”，层层深入，增强说服力。
- 实用表达：“This is not fair to others.” “In short, the disadvantages are greater...” 是总结类常用句型。
我眼中的手机生活（范文三）
Mobile phones have become part of our daily life. As a teenager, I use my phone every day. I think it brings both joy and problems.
I like using my phone to talk with friends. We send messages, share photos, and laugh together. It helps me feel close to them, even when we are not at school.
I also use my phone to learn. There are many useful apps for English, math, and science. I can review lessons or watch short videos to understand better.
However, I sometimes spend too much time on my phone. I stay up late watching videos or playing games. Then I feel tired the next day. I know this is not healthy.
So I decide to use my phone less. I will only use it for 30 minutes after homework. I believe balance is the key to a happy life with mobile phones.
手机已经成为我们日常生活的一部分。作为一名青少年，我每天都使用手机。我认为它既带来了快乐，也带来了问题。
我喜欢用手机和朋友聊天。我们发消息、分享照片、一起笑。即使不在学校，我也能感觉和他们很亲近。
我也用手机学习。有许多有用的英语、数学和科学类应用程序。我可以复习课程，或看短视频来更好地理解知识。
然而，我有时在手机上花太多时间。我会熬夜看视频或玩游戏，第二天就感到疲倦。我知道这不健康。
所以我决定少用手机。我将在完成作业后只使用30分钟。我相信，平衡是拥有健康手机生活的关键。
✍️点评与重点：
- 人称真实：使用第一人称“I”，表达个人经历，增强文章真实感。
- 情感表达：“feel close to them”, “laugh together” 等短语体现情感交流，适合记叙+议论结合文体。
- 升华主题：结尾提出“balance”（平衡）概念，提升立意，符合高分作文标准。
