扩展建议：

1. 每个主体段落保持"论点+解释+例子+数据"结构

2. 使用过渡句连接段落（e.g., "While acknowledging these benefits, it's crucial to recognize..."）

3. 插入权威数据（世界银行2023报告显示...，皮尤研究中心调查表明...）

4. 保持学术语气但避免过于复杂的句子结构

5. 结论段采用"三段式"重申观点-强调重要性-展望未来

实际写作时注意：

- 总字数控制在980-1020之间

- 每段首句明确表达观点

- 每个论点至少包含2个支撑论据

- 使用3种以上连接词（furthermore, conversely, consequently）

- 保持客观中立立场，避免绝对化表述

这个结构既符合英语学术写作规范，又通过递进式论证展现批判性思维，同时留有足够扩展空间满足字数要求。建议在扩展时注意段落间的逻辑衔接，使用具体案例（如ChatGPT对就业的影响）增强说服力。
