四级作文不跑题的核心是 “先抓准主题，再用模板框住内容”，5 个模板覆盖所有常考题型，每个模板都预留 “强制扣题位”，填内容时直接对标主题，想跑题都难。

　　一、先解决 “不跑题” 的 3 个前提(比模板更重要)

　　10 秒审题抓关键：圈出题目里的 “主题词 + 写作要求”。比如题目 “Should We Reduce Screen Time?”，主题词是 “screen time”，要求是 “是否该减少”，所有论点必须围绕 “屏幕时间” 和 “减少的必要性 / 没必要” 展开，别扯到 “如何选手机” 这类无关内容。

　　论点紧扣 “主题词”：每段开头用 “主题词 + 观点” 的句式，比如 “Reducing screen time helps improve our focus”(减少屏幕时间能提升专注力)，直接把主题和论点绑死，避免偏题。

　　例子必带 “主题词”：举例子时不说 “很多人效率低”，而说 “很多学生因长时间刷短视频(主题词相关)，写作业时频繁分心，效率下降”，用具体场景扣住主题。

　　二、5 个 “防跑题万能模板”(覆盖 99% 题型)

　　模板 1：现象类(常考：描述现象→分析原因→提建议，如 “短视频流行”“线上学习”)

　　开头（引入现象，必提主题词）Nowadays, 【主题词，如 the popularity of short videos】 has become a common phenomenon in our daily life. We can easily see 【具体现象，如 people watching short videos on buses, at restaurants or even during breaks】. This trend has aroused wide attention.

　　中间（分析原因，紧扣主题）There are two main reasons for this phenomenon. Firstly, 【原因 1.如 the convenience of smartphones makes it easy for people to access short videos anytime】. With 【主题词相关载体，如 mobile apps】, people can get entertainment in just a few minutes. Secondly, 【原因 2.如 short videos cover various topics, from life tips to knowledge sharing, which meets different people’s needs】.

　　结尾（提建议 / 总结，回归主题）To make 【主题词】 play a positive role, we should 【建议 1.如 control the time we spend on it】. What’s more, 【建议 2.如 choose more meaningful and educational content】. Only in this way can we benefit from 【主题词】 instead of being influenced negatively.

　　扣题提醒：每个段落都要出现 “主题词”，原因和建议必须针对主题的特点(如短视频的 “便捷性”“内容多样”)，别扯其他现象的原因。

　　模板 2：观点类(常考：同意 / 不同意某观点，如 “是否该上 AI 伦理课”“大学生是否该兼职”)

　　开头（亮明立场，锁定主题）When it comes to 【主题词，如 whether universities should offer AI ethics courses】, people have different opinions. Some think it’s unnecessary, but I firmly believe that 【你的立场，如 we should have such courses】.

　　中间（2 个论点 + 扣题论据）Firstly, 【论点 1.如 AI ethics courses help students avoid moral risks in future work】. For example, when students learn about 【主题词相关内容，如 the ethical limits of AI】, they will not develop technologies that harm society. Secondly, 【论点 2.如 such courses promote the healthy development of the AI industry】. With a clear understanding of ethics, students can create AI products that benefit people, which is the core goal of 【主题词相关领域，如 AI development】.

　　结尾（重申立场，升华主题）In conclusion, 【主题词】 is of great importance for 【相关群体，如 college students】. Taking 【主题词相关行动，如 AI ethics courses】 not only helps individuals grow but also contributes to social progress. So we should support 【你的立场】.

　　扣题提醒：立场一旦确定，所有论点都要 “支撑立场”，别出现 “既同意又不同意” 的模糊表述，论据必须和主题词直接相关(如谈 AI 伦理课，别举 “数学课” 的例子)。

　　模板 3：利弊类(常考：分析某事物的利弊，如 “社交媒体的利弊”“线上办公的优缺点”)

　　开头（引入主题，表明要分析利弊）In recent years, 【主题词，如 social media】 has become an important part of our life. It brings both benefits and drawbacks, which are worth discussing.

　　中间（先利后弊，各 1-2 点，紧扣主题）On the one hand, 【好处 1.如 social media helps us stay in touch with friends easily】. Even if we live in different cities, we can share our lives through 【主题词相关功能，如 videos or messages】. Another advantage is that 【好处 2.如 it provides a platform for learning】. We can get useful knowledge from 【主题词相关渠道，如 educational accounts】.

　　On the other hand, 【坏处 1.如 excessive use of social media wastes time】. Many people spend hours scrolling through 【主题词相关内容，如 short videos】 every day, ignoring work or study. Besides, 【坏处 2.如 it may spread false information】, which can mislead people and cause trouble.

　　结尾（平衡总结，给出建议）Overall, 【主题词】 is a double-edged sword. We should make good use of its advantages, such as 【好处 1/2】, and avoid its drawbacks by 【建议，如 controlling usage time】. In this way, we can enjoy the convenience of 【主题词】 without being harmed.

　　扣题提醒：“利” 和 “弊” 必须是主题词本身的特点，别把 “用户使用不当” 的问题归为主题词的 “弊”(如 “有人用社交媒体诈骗” 不是社交媒体的弊，而是人的问题，应改 “社交媒体易传播不实信息”)。

　　模板 4：应用文(常考：书信 / 通知，如 “邀请信”“活动通知”“建议信”)

　　（以 “邀请信” 为例，格式 + 内容双扣题）

　　I’m 【你的身份，如 Zhang Wei, a student from Class 2】. I’m writing to sincerely invite you to 【活动主题，如 give a lecture on English writing】, which will be held by our class to 【活动目的，如 improve students’ writing skills】.

　　The details of the activity are as follows: First, it will start at 【时间，如 2:00 pm on October 20th】 and last for 1.5 hours. Second, the location is 【地点，如 the meeting room on the 3rd floor of the teaching building】. During the lecture, we hope you can share 【主题相关内容，如 tips on avoiding off-topic in writing and using proper structures】, which is exactly what we need for 【相关需求，如 the upcoming CET-4 exam】.

　　We would be very grateful if you could accept our invitation. Please reply to us at 【联系方式，如 123456789@qq.com】 by October 15th.

　　Yours sincerely,

　　扣题提醒：应用文的 “主题” 是 “活动 / 目的”，所有内容(时间、地点、邀请理由)都要服务于这个主题，别写无关的个人寒暄(如别扯 “最近天气变冷，您要注意保暖”)。

　　模板 5：图表类(常考：柱状图 / 折线图 / 饼图，如 “某城市出行方式变化”“大学生兼职收入来源”)

　　开头（描述图表，抓主题数据）The chart above shows 【图表主题，如 the changes in travel modes in City A from 2018 to 2023】. From the data, we can clearly see that 【核心变化，如 the number of people taking public transport increased sharply, while the number of those driving private cars decreased slightly】.

　　中间（分析原因，紧扣数据背后的主题）There are two main reasons for this change. Firstly, 【原因 1.如 the government improved public transport services】. More buses and subways were added, making it more convenient for people to choose 【主题相关方式，如 public transport】. Secondly, 【原因 2.如 people’s awareness of environmental protection increased】. They prefer low-carbon travel modes like 【主题相关方式，如 buses or bikes】 to reduce pollution, which leads to the decline in private car use.

　　结尾（总结趋势，升华主题）In conclusion, the changes in 【图表主题，如 travel modes】 reflect 【深层趋势，如 the city’s development in public services and people’s environmental awareness】. It is expected that 【未来趋势，如 public transport will become more popular】, which is good for both the city and its residents.

　　扣题提醒：描述图表时别只列数据，要 “总结数据变化”(如 “从 20% 涨到 50%”→“大幅增长”)，分析原因必须和 “数据变化” 相关(如公共交通人数涨，原因就得是 “公交服务改善”，别扯 “油价上涨” 除非数据里有私家车减少)。

　　最后：模板用对不跑题的关键 ——“填内容时盯紧主题词”

　　每个模板里的【主题词】【具体现象】等占位符，一定要填题目里的核心词，比如题目是 “Online Shopping”，就别填 “Online Games”;举例子时，每句话都要能看到 “主题词” 的影子(如谈网购，例子就说 “很多人在网上买日用品，省时又省力”)。
