雅思曲线图写作大纲
雅思写作Task 1中的曲线图（Line Graph）是常见题型之一，要求考生在20分钟内完成150字以上的描述，掌握正确的写作框架和技巧，可以帮助考生高效组织语言，准确呈现数据趋势，本文将提供最新数据示例和权威分析，帮助考生提升写作质量。
曲线图写作基本结构
雅思曲线图写作通常采用四段式结构：
- 引言（Introduction）：改写题目，说明图表主题。 Overview）**：总结主要趋势，不涉及细节数据。
- 细节段1（Detail Paragraph 1）：描述关键数据变化。
- 细节段2（Detail Paragraph 2）：补充对比或次要趋势。
1 引言（Introduction） 避免照抄。
- 原题：The graph below shows the changes in the number of international students in Australia from 2015 to 2023.
- 改写：The line graph illustrates the fluctuation in the population of overseas students studying in Australia between 2015 and 2023.
2 概述（Overview）
用2-3句话概括整体趋势，
"Overall, the number of international students in Australia experienced steady growth until 2019, followed by a sharp decline during the pandemic. However, figures rebounded significantly after 2021."
中提及具体数字，仅描述趋势（上升、下降、波动、稳定）。

2 范文段落
Introduction：
"The line graph depicts the global electricity generation from renewable sources, measured in terawatt-hours (TWh), from 2015 to 2023."
Overview：
"Overall, renewable energy production showed consistent growth throughout the period, with a particularly sharp rise after 2019. Solar and wind power contributed significantly to this upward trend."
Detail Paragraph 1：
"In 2015, renewable energy generation stood at 5,200 TWh, rising gradually to 6,100 TWh by 2017. The next two years saw a more pronounced increase, reaching 7,400 TWh in 2019."
Detail Paragraph 2：
"Post-2019, growth accelerated dramatically, with figures surging to 8,900 TWh in 2021. By 2023, renewable electricity production hit a record high of 10,500 TWh, reflecting global policy shifts towards sustainability."
常见错误及改进建议
1 错误1：机械列举数据
- 错误写法：In 2015 it was 5,200, in 2017 it was 6,100, and in 2019 it was 7,400.
- 改进写法：Between 2015 and 2019, renewable energy output climbed steadily from 5,200 TWh to 7,400 TWh.
2 错误2：忽略对比
- 错误写法：Coal use decreased.
- 改进写法：While coal consumption fell by 15%, renewable energy adoption expanded by 40% during the same period.
3 错误3：时态混乱
- 错误写法：In 2023, renewable energy increases.
- 改进写法：By 2023, renewable energy had increased significantly.
