雅思写作Task 1中，线条图（Line Graph）是常见题型之一，这类题目要求考生在20分钟内完成150字以上的数据分析报告，许多考生因缺乏清晰的写作框架或词汇单一而失分，本文将结合官方评分标准，提供实用写作模板、高分词汇及完整范文，帮助考生快速掌握线条图写作技巧。
线条图写作核心结构
根据剑桥雅思官方指南，高分线条图作文需包含四部分：
-
引言段（Introduction） 说明图表展示的时间范围、数据类别及单位，避免直接抄袭题目，使用同义替换：
- 原题：The graph shows changes in car ownership in Britain from 1960 to 2000
- 改写：The line graph illustrates how the proportion of British households owning cars changed over a 40-year period between 1960 and 2000.

- 重要波动（峰值、谷值、交叉点）
- 对比关系（e.g. "Surpassing B in 1985, A became the dominant category"）

7分范文与解析
The graph below shows electricity production (in terawatt hours) in France and Germany between 1980 and 2010.
范文：
The line graph compares how much electricity was generated in two European nations over three decades, measured in terawatt hours.
Overall, France’s electricity output grew steadily despite minor fluctuations, overtaking Germany in the final decade. By contrast, Germany’s production remained relatively stable with a slight downward trend after 1990.
In 1980, Germany produced significantly more electricity at 120 terawatt hours, nearly double France’s 65 terawatt hours. Over the next 15 years, both countries saw growth, though Germany’s increase was more erratic with a sharp drop in 1985. By 1995, the gap had narrowed to just 20 terawatt hours.
From 1995 onwards, France’s production rose consistently, peaking at 150 terawatt hours in 2010. Meanwhile, Germany’s output declined gradually to 110 terawatt hours by 2005 before recovering slightly to 120 terawatt hours at the end of the period. Notably, France surpassed Germany around 2002, establishing a clear lead in the latter years.
考官评析：
- Task Achievement：清晰呈现所有关键数据，包含对比与转折
- Coherence：分段合理，使用while, meanwhile等连接词
- Lexical Resource：避免重复（e.g. 用overtake/surpass替换exceed）
- Grammar：混合使用简单句与复杂句（e.g. Despite..., ...）
常见错误规避
- 数据误读：将“output”误解为“consumption”，务必核对坐标轴标签
- 时态混乱：过去数据用一般过去时（produced），预测用将来时（is projected to）
- 过度描述：非关键波动（如<5%的变化）可忽略，优先分析显著特征
- 主观臆断：避免解释原因（e.g. “由于政策改革”），仅陈述可见数据
备考建议
- 限时训练：用官方真题练习，15分钟完成写作，5分钟检查语法与数据准确性
- 词汇分类：建立个人词库（如上升/下降/稳定三类，每类储备5个替换词）
- 范文拆解：分析剑桥雅思范文的段落分配与数据选取逻辑
- 工具辅助：Grammarly检查语法，IELTS-Bro纠正常见中式英语表达
线条图写作的核心在于用简洁准确的语言呈现数据间的关联与差异，通过掌握趋势分组法、积累动态词汇链，考生完全可以在150字内展现分析能力，考前重点练习3-5篇不同主题的图表，写作时自然能快速构建文章框架。
雅思写作并非考察专业领域知识，而是测试信息转述的清晰度与语言控制力，线条图作为高频题型，只要掌握数据筛选优先级和标准化表达，完全可能成为提分突破口，大量考生实践证明，针对性的20小时训练足以将Task 1成绩从5.5提升至6.5+。
