英文饼状图作文写作步骤
引言(Introduction)
用1-2句话概括图表内容,避免直接复制标题,可适当改写:
"The provided pie chart displays the proportion of energy sources used in a country during 2022."
概述(Overview)
简要总结图表的主要特征,无需涉及细节数据:
"Overall, fossil fuels dominated the energy mix, while renewable sources accounted for a smaller share."
细节描述(Detailed Description)
分段描述具体数据,可按占比从高到低或按类别逻辑排序:
- 最高占比部分:
"Coal represented the largest segment at 35%, followed by natural gas with 28%." - 中间部分:
"Nuclear energy contributed 15%, whereas hydroelectric power made up 12%." - 最低占比部分:
"Other renewables, such as solar and wind, combined for only 10%."
比较与分析(Comparison & Analysis)
适当对比数据或分析可能的原因(适用于议论文或报告):
"The heavy reliance on fossil fuels suggests limited investment in clean energy infrastructure."
常用词汇与句型

范例作文
The pie chart below shows the percentage of online shopping categories in 2023.
范文:
The given pie chart outlines the distribution of different online shopping categories in 2023.
Overall, electronics and clothing were the most popular sectors, while other niches like books and home appliances had smaller market shares.
Electronics dominated the chart with 38%, reflecting high consumer demand for gadgets. Clothing ranked second at 29%, indicating steady growth in fashion e-commerce. Food and groceries accounted for 17%, likely due to increased delivery services. The remaining categories—books (8%), home appliances (5%), and others (3%)—combined for less than a fifth of total sales.
This data suggests that consumers prioritize technology and apparel when shopping online, possibly influenced by convenience and promotional campaigns.
提升技巧
- 多样化表达:避免重复使用"account for",可替换为"represent"或"comprise"。
- 逻辑衔接:使用过渡词(e.g., however, in comparison)增强连贯性。
- 数据准确性:核对图表信息,避免主观臆测。
掌握饼状图写作不仅能应对考试,还能增强数据分析能力,通过清晰的结构和精准的语言,读者可以快速抓住核心信息,使文章更具说服力,多练习不同主题的图表,逐步提升描述和分析水平,最终在学术或职业场景中游刃有余。
