- **问题提出**：明确文章要讨论的核心问题或观点。
- **论点陈述**：简要概述文章的主要论点。

**示例**：
"In the era of rapid technological advancement, artificial intelligence (AI) has become a transformative force in various industries. However, its impact on employment remains a topic of heated debate. This essay will argue that while AI may displace certain jobs, it also creates new opportunities and enhances productivity."

#### 2. 主体部分（Body）

For instance, in the manufacturing sector, robots have taken over assembly line jobs, allowing employees to engage in product design and innovation. Secondly, AI-driven technologies are creating entirely new industries, such as autonomous vehicles and personalized medicine, which require a skilled workforce. While some argue that AI will lead to widespread unemployment, it is important to note that technological advancements have historically led to job transformation rather than elimination."

#### 3. 结论（Conclusion）

As we move forward, embracing AI with a balanced approach will be key to shaping a prosperous future."
