雅思写作Task 1中,折线图(Line Graph)是高频题型之一,掌握核心描述逻辑、数据对比技巧以及趋势分析能力,是快速提分的关键,以下结合最新全球雅思数据与官方评分标准,提供可复用的模板框架与实战案例。
折线图高分结构模板
根据剑桥雅思官方范文分析,折线图描述需包含4个核心段落:
-
引言段(Introduction) 明确时间范围与数据主题。
例:The line graph illustrates changes in the proportion of renewable energy production in five European countries (Germany, France, Italy, Spain, and the UK) between 2000 and 2022.
段(Overview)
不写具体数据*,总结2-3条核心趋势(如最高/最低值、最大变化幅度、交叉点)。
例:*
Overall, Germany consistently led in renewable energy output, while the UK showed the most significant growth. All countries experienced an upward trend except for a temporary decline in France after 2015. -
细节段1(Detail 1)
按时间或数值分组描述关键数据,突出对比与转折。 -
细节段2(Detail 2)
补充剩余信息,避免重复。
2024年最新数据实战案例
以全球新能源汽车销量趋势为例(数据来源:国际能源署IEA 2024年报告):
年份 | 中国(万辆) | 欧洲(万辆) | 美国(万辆) |
---|---|---|---|
2020 | 120 | 110 | 30 |
2021 | 290 | 190 | 60 |
2022 | 520 | 250 | 90 |
2023 | 750 | 310 | 140 |
范文片段:
From 2020 to 2023, China dominated the global electric vehicle market, with sales surging from 1.2 million to 7.5 million units—a six-fold increase. Europe maintained steady growth, reaching 3.1 million vehicles by 2023, while the U.S. lagged behind despite tripling its sales volume. Notably, the gap between China and other regions widened significantly after 2021.

Data compiled from IEA's "Global EV Outlook 2024" (https://www.iea.org/reports/global-ev-outlook-2024).
提分技巧:避免5个常见错误
-
机械罗列数据
错误示范:In 2020, China was 120. In 2021, it increased to 290.
修正:
China's sales skyrocketed from 1.2 million in 2020 to 2.9 million the following year. -
时态混乱
- 过去时间段用一般过去时(2000-2020)
- 预测未来趋势用一般将来时或情态动词(projected to rise)
-
单位遗漏
必须标明单位(thousands, %, tonnes等)。 -
过度使用increase/decrease
替换词汇:- 急剧变化:soar/plummet/surge/collapse
- 平稳变化:gradual rise/marginal decline
-
忽略数据对比
加入比较句式:While Germany accounted for 40% of the total, the figure for Spain was merely 12%.
