在英语写作中,线图（Line Graph）作文是常见的数据分析题型，尤其在雅思、托福等考试中频繁出现，掌握线图作文的写作技巧，不仅能提升应试能力，还能增强逻辑表达能力，本文将通过范例解析，帮助读者轻松掌握线图作文的写作方法。
线图作文的基本结构
线图作文通常分为四段：引言、概述、细节分析和结尾，这种结构清晰明了，便于阅卷老师快速抓住重点。
-
引言（Introduction）
开篇需简要说明图表内容，包括时间范围、数据主题和单位，避免直接复制题目，要用自己的语言改写。
范例：
The line graph illustrates the changes in the number of tourists visiting two coastal cities, City A and City B, between 2010 and 2020. The data is measured in thousands.
Overview）*
概括图表的主要趋势或显著特征，无需涉及具体数据，这是得分的关键部分。
范例：*
Overall, both cities experienced fluctuations in tourist numbers, but City A showed a steady upward trend, while City B’s figures declined sharply after 2015. -
细节分析（Details）
分段描述具体数据变化，注意逻辑顺序（如时间、高低值对比），使用连接词使行文流畅。
范例：
In 2010, City A attracted around 50,000 visitors, slightly fewer than City B’s 60,000. Over the next five years, both destinations saw growth, with City A surpassing City B by 2015. However, from 2015 onwards, City B’s popularity dropped significantly, reaching a low of 30,000 in 2020. -
Conclusion）
可选择性总结趋势，或提出合理推测，避免重复概述内容。
范例：
The data suggests that City A became a more favored destination over the decade, possibly due to improved infrastructure or marketing efforts.
高分技巧
-
时态与语态
- 过去时间段用一般过去时（e.g., increased, declined）。
- 预测未来趋势用将来时或情态动词（e.g., is projected to rise, may stabilize）。
- 被动语态可增强客观性（e.g., It can be observed that...）。
-
多样化表达
避免重复使用“increase”或“decrease”，可替换为：- 上升：rise, grow, climb, surge
- 下降：fall, drop, decline, plummet
- 波动：fluctuate, vary, experience ups and downs
-
数据引用
精确描述数据时，注意介词使用：- 从A到B：from...to...
- 达到峰值：peaked at...
- 稳定在：remained stable at...
常见错误与修正
-
数据误读
错误： City A had more tourists than City B every year.
修正： City A’s tourist numbers exceeded City B’s after 2015. -
过度描述
避免逐点罗列数据，应分组对比（如先写整体趋势，再分阶段比较）。 -
忽略单位
务必注明数据单位（e.g., millions, percentage points），避免歧义。
完整范例
** The graph below shows electricity consumption in three countries from 2000 to 2020.
范文：
The line graph compares the changes in electricity usage in Country X, Country Y, and Country Z over two decades, measured in gigawatts.
Overall, all three countries witnessed an increase in electricity demand, though at varying rates. Country X’s consumption grew dramatically, while Country Z showed the least progress.
In 2000, Country Y had the highest electricity usage at 50 GW, followed by Country X (30 GW) and Country Z (20 GW). Over the next ten years, Country X’s figures surged to 80 GW, overtaking Country Y, which rose moderately to 60 GW. Meanwhile, Country Z’s growth was minimal, reaching just 25 GW by 2010.
From 2010 to 2020, the gap widened further. Country X’s consumption nearly doubled, peaking at 150 GW, whereas Country Y’s increase slowed to 90 GW. Country Z remained the lowest, despite a slight uptick to 40 GW.
The stark differences may reflect industrialization speeds, with Country X likely prioritizing energy-intensive sectors.
