Part 3: 范文分析

我们以一个经典的初中议论文话题为例："Should students be allowed to use mobile phones at school?" (学生应该被允许在学校使用手机吗？)

Should Students Be Allowed to Use Mobile Phones at School?

(第一段：引言段) In today's digital world, mobile phones have become an indispensable part of our daily lives. However, the question of whether students should be allowed to use them at school has sparked a heated debate. While some people believe that phones can be useful learning tools, I firmly hold the view that they should be banned during school hours.

分析:

• 背景引入: "In today's digital world..." 点明了手机的普遍性。
• 双方观点: "While some people believe... I firmly hold the view..." 简要提及了不同看法，并明确了我的立场。

(第二段：主体段一 - 第一个论据) First and foremost, mobile phones can be a major distraction for students. The primary purpose of school is to provide a focused environment for learning. If students are allowed to use their phones, they might be tempted to check social media, play games, or send text messages instead of paying attention to the teacher. This will undoubtedly have a negative impact on their academic performance. For example, a student might be distracted by a message during an important lesson and miss key information, leading to poor grades.

分析:

• 主题句: "First and foremost, mobile phones can be a major distraction for students." 清晰地提出了第一个分论点。
• 解释: 解释了为什么手机会分散注意力，影响学习环境。
• 举例: "For example, a student might be distracted..." 用一个具体的场景来支持论点。

(第三段：主体段二 - 第二个论据) Furthermore, the use of mobile phones in school can lead to other problems, such as cheating and cyberbullying. With smartphones, students can easily find answers online during exams, which is unfair to those who study hard. Moreover, social media platforms can be used to spread rumors or hurtful comments about classmates, creating a hostile and unsafe environment. These issues not only violate the rules but also harm students' moral development.

分析:

• 主题句: "Furthermore, the use of mobile phones in school can lead to other problems..." 提出了第二个分论点。
• 解释: 阐述了手机可能带来的作弊和校园网络欺凌问题。
• 论据: "Moreover..." 进一步说明了这些问题带来的严重后果。

(第四段：让步段) Admittedly, some people argue that mobile phones can be used as educational tools. For instance, students can use them to look up new words, access educational apps, or communicate with teachers about homework. However, these benefits can be easily misused. Schools already provide computers and libraries for research, so there is no real need for students to use their personal phones for academic purposes during class time. The potential for distraction and misuse far outweighs the supposed advantages.

分析:

• 承认对方观点: "Admittedly, some people argue that..." 承认了手机作为教育工具的潜在好处。
• 转折和反驳: "However, these benefits can be easily misused..." 指出这些好处很容易被滥用，并用学校已有的资源来反驳，认为手机的坏处大于好处。

(第五段：结论段) In conclusion, although mobile phones have their place in modern society, they should not be allowed in the classroom. They distract students from learning and can lead to serious issues like cheating and cyberbullying. To ensure a positive and effective learning environment, schools must enforce a strict no-phone policy. Only by doing so can students truly focus on their studies and grow into responsible individuals.

分析:

• 重申观点: "In conclusion, although... they should not be allowed..." 再次强调了我的立场。
• 总结论据: "They distract students... and can lead to..." 简要回顾了主要论点。
• 结尾句: "Only by doing so can students..." 提出了明确的期望和结论，有力地收尾。
