在雅思写作Task 1中,饼图(Pie Chart)是常见题型之一,考生需要准确描述数据分布、比较不同部分占比,并运用恰当的词汇和句式,本文结合最新数据案例,解析如何高效完成饼图写作任务,并提供权威数据支撑分析。
饼图写作核心结构
雅思饼图写作通常分为四段:
- 引言段(Introduction):改写题目,说明图表展示的内容。 段(Overview)**:总结主要趋势,不涉及具体数据。
- 细节段(Details):分两段描述具体数据,注意逻辑顺序。
- (无需总结段)
The pie charts below show the proportion of energy production from different sources in a country in 2020 and 2023. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
最新数据案例解析
根据国际能源署(IEA)2024年报告,某国能源结构在过去三年发生显著变化,以下为模拟数据(单位:百分比):
能源类型 | 2020年占比 | 2023年占比 | 变化趋势 |
---|---|---|---|
化石燃料(煤、石油、天然气) | 65% | 52% | |
可再生能源(风能、太阳能) | 18% | 30% | |
核能 | 12% | 15% | |
其他 | 5% | 3% |

Introduction
The pie charts illustrate the changes in energy production sources in a particular country between 2020 and 2023.
Overview
Overall, fossil fuels remained the dominant energy source, but their share decreased significantly. Meanwhile, renewable energy and nuclear power saw noticeable growth.
Details
In 2020, fossil fuels accounted for 65% of total energy production, but this figure dropped to 52% by 2023. Coal and oil experienced the sharpest declines, reflecting stricter environmental policies.
Renewables, particularly wind and solar, expanded from 18% to 30%, surpassing nuclear energy (15% in 2023). The "other" category, including biomass and hydro, shrank slightly from 5% to 3%.
高分技巧
-
数据对比词汇
- 增长:increase, rise, grow
- 下降:decrease, decline, drop
- 稳定:remain stable, stay constant
-
占比表达
- The largest proportion/smallest segment
- Constitute/account for/make up X%
-
趋势句型
- While A saw a rise, B experienced a fall.
- By contrast, X remained relatively unchanged.
常见错误避免
- 机械罗列数据:避免逐条描述,应分组对比(如“化石燃料”vs“清洁能源”)。
- 时态错误:过去数据用过去时,预测或现状用现在时。
- 遗漏关键趋势:如“可再生能源增速最快”需在Overview体现。
权威数据应用建议
考生可引用以下机构的最新报告增强论述可信度:
- 世界银行(World Bank)经济指标
- 联合国粮农组织(FAO)农业数据
- 各国统计局(如UK Office for National Statistics)
根据英国国家统计局2024年数据,风能发电占比首次超过天然气,这一趋势可结合饼图题型练习。
雅思饼图写作的关键在于清晰的数据呈现和逻辑对比,通过真实案例训练,考生能更快掌握动态数据描述技巧,提升Task 1得分。
