From my perspective, while online education presents certain challenges, its benefits in promoting equal learning opportunities far outweigh the drawbacks.
主体段：论证观点，逻辑展开
主体段是文章的核心，通常包含2-3个段落，每个段落围绕一个分论点展开，采用“主题句-解释句-例证句-小结句”的结构，以下是各部分常用句式：
主题句（Topic Sentence）
- 开门见山，概括段落核心观点，通常位于段首。

例证句（Example/Evidence）

小结句（Concluding Sentence）

- Without addressing this issue, the negative consequences are likely to exacerbate.
示例段落：
The primary advantage of online education lies in its ability to break geographical barriers and provide equal learning opportunities.

For instance, in rural regions of China, initiatives like the “National Cloud Classroom” have connected thousands of students with top-tier instructors in urban cities, significantly narrowing the educational gap. Therefore, it is evident that online education plays a pivotal role in promoting educational equity.
结论段：总结观点，升华主题
结论段的作用是概括全文论点，重申立场，并可能提出建议或展望未来，通常包含2-3句话，常用句式如下：

-
重申立场句（换用同义词表达观点，避免重复）
Thus, while [对立观点] holds some truth, the benefits of [个人观点] make it a more viable solution.
-
建议/展望句（提出解决方案或未来趋势）
- To maximize the positive impact of [话题], it is imperative that [具体建议].
- Looking ahead, further efforts should be made to [未来行动方向].
示例：
In conclusion, the aforementioned arguments demonstrate that online education offers significant advantages in promoting accessibility and equity, despite challenges like the digital divide. Thus, while concerns about its limitations are valid, the benefits of making education more inclusive make it a crucial development in modern society. To maximize its potential, governments and educational institutions should collaborate to improve internet infrastructure and provide digital literacy training for underserved groups.

FAQs 相关问答
问题1：雅思大作文是否需要使用复杂句式？
解答：雅思写作评分标准中，“语法多样性与准确性”占25%的分值，适当使用复杂句（如定语从句、状语从句、倒装句等）能展示语法能力，但前提是确保句式准确且清晰，考生应避免为了追求复杂而使用生僻句式，导致语法错误或逻辑混乱，建议在简单句正确的基础上，逐步融入复合句和复杂句，保持句式多样性与准确性的平衡。
问题2：如何避免主体段论点重复？
解答：主体段论点重复通常源于分论点设计不清晰或例证角度单一，在构思阶段需确保每个主体段的分论点有明确的区分度（如“原因1 vs 原因2”“优点 vs 缺点”），例证句应聚焦分论点的核心，避免与其他段落案例重叠，若一段讨论“经济影响”，另一段可讨论“社会影响”，通过不同维度展开论述,确保逻辑层次分明。
