如何构建高分作文结构

引言部分（Introduction）

开头段落需要清晰表达文章主旨，通常包括：

• 背景句：简要介绍人口问题的普遍性。
• 改写题目：用自己的语言复述题目要求。
• 观点句：明确表达自己的立场或文章方向。

示例：
"The rapid growth of the global population has become a pressing issue in recent decades. While some argue that this trend exacerbates environmental degradation and resource scarcity, others believe technological advancements can mitigate these challenges. This essay will examine the problems caused by overpopulation and propose viable solutions."

主体段落（Body Paragraphs）

主体部分通常由2-3段组成，每段围绕一个核心论点展开，并辅以例证和分析。

段落结构建议：

• 主题句：明确本段讨论的核心观点。
• 解释扩展：进一步阐述该观点，提供逻辑推理。
• 例证支持：引用数据、研究或具体案例增强说服力。
• 衔接分析：说明该论点如何支持全文主旨。

示例段落（人口增长的影响）：
"One major issue caused by population growth is the strain on natural resources. As the number of people increases, demand for food, water, and energy rises exponentially. For instance, the United Nations estimates that global food production must increase by 70% by 2050 to meet the needs of the projected 9.7 billion population. This surge in demand often leads to overexploitation of arable land and freshwater sources, resulting in long-term environmental damage. Without sustainable management practices, resource depletion could trigger widespread economic and social instability."

结论部分（Conclusion）

结尾段落需要总结全文，并重申核心观点，避免引入新信息。

示例：
"In conclusion, population growth presents significant challenges, including resource scarcity and environmental degradation. However, through technological innovation, sustainable policies, and international cooperation, these issues can be effectively managed. Governments and individuals must take proactive steps to ensure a balanced approach to demographic changes."

实战演练

"In many countries, the proportion of elderly people is increasing. What problems does this trend bring, and how can they be addressed?"

参考范文：
"The aging population has become a critical demographic shift in many nations, particularly in developed countries like Japan and Germany. This trend poses several challenges, including increased healthcare costs and labor shortages, but potential solutions exist to mitigate these issues.

One major problem is the financial burden on healthcare systems. Elderly individuals typically require more medical attention, leading to higher public expenditure. For instance, in Japan, healthcare spending for citizens over 65 accounts for nearly 35% of the national budget. This strain could compromise the quality of care for other age groups if not managed properly.

Another concern is the shrinking workforce. As more people retire, fewer young workers are available to sustain economic productivity. Countries like Italy are already experiencing labor shortages in key industries, which could hinder long-term economic growth.

To address these challenges, governments could implement policies to encourage higher birth rates, such as subsidized childcare and parental leave programs. Additionally, raising the retirement age and promoting lifelong learning can help retain experienced workers in the labor market. Technological advancements, such as automation and AI, could also offset workforce declines in certain sectors.

While an aging population presents undeniable challenges, proactive measures can transform this demographic shift into an opportunity for societal adaptation and innovation."

掌握人口类话题的写作技巧，不仅有助于雅思备考，也能提升对社会问题的分析能力，通过清晰的逻辑结构、具体的例证和多样的语言表达，考生可以在写作中展现批判性思维,从而获得理想分数。
