议论文：构建逻辑说服力的核心

议论文是四级写作最常见的类型，通常要求表达观点、分析原因或讨论利弊。高分关键在于清晰的结构：引言（提出观点）、主体（论证支持）和结论（重申观点）。万能句型模板能帮你快速搭建框架，避免从零开始。以下是针对议论文的详细素材，包括开头、主体和结尾模板，以及一个完整示例。

1. 开头模板：引出话题并明确立场

开头要简洁有力，吸引阅卷老师注意。常用模板包括背景描述和观点陈述。

  • 模板1：背景+观点
    “With the development of society, [话题] has become a hot issue. In my opinion, [你的观点].”
    示例：With the development of society, online learning has become a hot issue. In my opinion, it is more beneficial than traditional classroom teaching.

这些模板能让你在1-2句内完成开头，节省时间。支持细节：开头避免冗长，控制在30词以内；使用过渡词如”with”、”nowadays”增强逻辑性。

2. 主体模板：提供论据和例子

主体是文章的核心，通常2-3段，每段一个论点+支持细节。使用连接词保持连贯。

  • 模板1：原因分析
    “Firstly, [原因1] leads to [结果]. For example, [具体例子]. Secondly, [原因2] also contributes to [结果].”

支持细节：每个论点后加1-2个具体例子，避免空洞；使用”firstly/secondly”、”for instance”等词引导，确保段落长度40-60词。

3. 结尾模板：总结并升华

结尾要重申观点，避免新信息，给人深刻印象。

  • 模板1：重申+呼吁
    “In conclusion, [重申观点]. Let us [呼吁行动].”

支持细节：结尾控制在20-30词，使用”in conclusion”或”all in all”标志结束；升华到个人或社会层面，提升分数。

完整议论文示例：热点话题“大学生是否应该兼职”

假设题目：Should college students take part-time jobs?

高分范文（约150词）：

With the development of society, part-time jobs for college students have become a hot issue. In my opinion, they are beneficial if managed properly.

Firstly, part-time jobs help students gain practical experience. For example, working as a tutor allows them to apply classroom knowledge to real life. Secondly, they develop time management skills. Take my roommate as an example; after working in a café, he became more organized and his grades improved. However, on the other hand, overwork may lead to fatigue. For instance, some students skip classes due to long shifts, which harms their studies.

In conclusion, part-time jobs have both pros and cons. Let us balance work and study to make the most of them.

假设题目：Explain the causes and effects of smartphone addiction.

高分范文（约160词）：

Smartphone addiction refers to the excessive use of mobile phones that interferes with daily life. It plays a vital role in modern society.

The main reason for this phenomenon is the convenience of apps. For example, social media like WeChat provides instant entertainment, making users check their phones constantly. As a result, it leads to reduced face-to-face communication. Another cause is the fear of missing out (FOMO). Take teenagers as an example; they often feel anxious without notifications, which affects their sleep quality. Overall, these effects include poor concentration and eye strain.

In summary, smartphone addiction stems from convenience and anxiety. We should set usage limits to maintain balance.

范文使用了开头模板1、主体模板1和2、结尾模板1。关键词如”excessive use”、”FOMO”、”eye strain”展示词汇深度。

应用文：实用格式和礼貌表达

高分范文（约140词）：

Dear President Wang,

I am writing to suggest improvements to our campus facilities. As a sophomore, I have noticed some issues that affect student life.

Firstly, the dormitory air conditioning is often broken, which causes discomfort in summer. For instance, last month, many students couldn’t sleep well due to the heat. Secondly, the cafeteria lacks healthy options. I suggest adding more vegetable dishes, as this would promote better nutrition. This change would encourage students to eat healthier and improve their overall well-being.

I hope these suggestions will be considered. Thank you for your attention.

Best regards,
Li Ming
