引言：为什么英语四级六级写作如此重要？
大学英语四级（CET-4）和六级（CET-6）考试是中国大学生英语能力的重要衡量标准，其中写作部分往往是最让考生头疼的环节。许多学生在词汇和阅读上表现不错，但一到写作就感到无从下手。根据历年数据，写作部分占总分的15%，满分105分（四级）或106.5分（六级），但平均分往往徘徊在及格线附近。这主要是因为写作要求考生在30分钟内完成一篇120-180词（四级）或150-200词（六级）的短文，涉及议论文、说明文和应用文等多种体裁。
本指南将全面覆盖这些体裁，提供详细的写作指导、真题解析和高分模板。通过学习这些内容，你将掌握结构化写作技巧，提升逻辑表达能力，从而轻松应对考试写作难题。无论你是四级新手还是六级冲刺者，这篇文章都将为你提供实用工具，帮助你从“写作恐惧”转向“写作自信”。
写作的核心在于“清晰、逻辑和语言多样性”。我们将从基础入手，逐步深入，确保每个部分都有主题句和支撑细节。记住，高分作文不是靠死记硬背，而是通过练习和模板灵活应用。接下来，我们逐一拆解。
议论文写作：构建逻辑论证的艺术
议论文是四级六级写作中最常见的体裁，约占总写作题目的60%。它要求考生表达观点、分析问题并给出结论。主题通常涉及社会热点、教育、科技或环境保护等。议论文的结构是关键：引言（提出观点）、主体（论证观点）和结论（总结并展望）。目标是使用连接词（如however, moreover）使文章流畅，避免简单句堆砌。
主题句与支撑细节
议论文的每个段落都应以一个清晰的主题句开头，然后用2-3个支撑句扩展。支撑细节可以是事实、例子或数据，确保论点有说服力。例如，在讨论“大学生是否应该兼职”时，引言主题句可以是：“In my opinion, college students should take part-time jobs to gain practical experience.” 主体段落则用细节支持：兼职帮助学生了解职场（细节1），并培养时间管理能力（细节2）。
高分模板：议论文通用框架
以下是一个四级/六级通用模板，适用于大多数议论文题目。模板强调平衡观点（pros and cons），字数控制在150词左右。
模板结构：
引言（Introduction, 20-30词）：背景句 + 观点句。
- 背景句：With the development of society, [主题] has become a hot topic.
- 观点句：As far as I am concerned, [你的观点].
主体（Body, 80-100词）：2-3个段落，每个段落一个论点 + 例子。
- 论点1：Firstly, [论点]. For example, [具体例子].
- 论点2：Secondly, [论点]. Moreover, [进一步解释].
- （可选）反方观点：However, some people argue that [反方]. But I believe [反驳].
结论（Conclusion, 20-30词）：总结 + 呼吁。
- In conclusion, [重申观点]. Therefore, we should [建议].
完整例子：四级真题风格题目“Should College Students Use Smartphones in Class?”
Should College Students Use Smartphones in Class?
With the popularity of smartphones, whether college students should use them in class has sparked debate. As far as I am concerned, smartphones should be banned in classrooms to ensure learning efficiency.
Firstly, smartphones distract students from lectures. For instance, a recent survey shows that 70% of students admit to checking social media during class, leading to poor academic performance. Moreover, using phones prevents active participation in discussions, which is essential for knowledge acquisition.
Secondly, smartphones may cause cheating issues. For example, some students use them to access answers during exams, undermining fairness. However, proponents argue that phones can be useful for quick information lookup. But I believe the risks outweigh the benefits, as self-discipline is often lacking.
In conclusion, banning smartphones promotes better focus and integrity. Therefore, universities should enforce strict policies to create an ideal learning environment.

真题解析：2019年6月四级真题“Online Shopping”
题目：Advantages and Disadvantages of Online Shopping.
解析：这是一个典型的利弊分析议论文。高分作文需平衡观点，避免偏激。满分范文通常使用对比连接词（while, on the other hand）。
高分范文示例（约160词）： Online shopping has gained popularity in recent years. While it offers convenience, it also has drawbacks.
On the one hand, online shopping saves time and energy. For example, consumers can buy goods from home without visiting stores, which is especially helpful for busy students. Additionally, it provides a wider variety of products at competitive prices.
On the other hand, risks exist. Products may not match descriptions, leading to disputes. Moreover, personal information leakage is a concern.
In summary, online shopping is beneficial if used wisely. Shoppers should choose reliable platforms to avoid pitfalls.
得分点：结构清晰（3段式），词汇多样（gained popularity, pitfalls），无语法错误。常见错误：忽略平衡观点，导致低分。

主题句与支撑细节
每个段落以说明性主题句开头，如“How can we reduce plastic waste?” 然后用步骤或原因支撑：步骤1（分类回收）、步骤2（使用可重复用品）。细节需具体，避免抽象。
高分模板：说明文通用框架
