在雅思写作Task 1中,线形图(Line Graph)是最常见的题型之一,考生需要准确描述数据趋势、比较变化,并运用恰当的词汇和句式,本文将结合最新数据示例,分析线形图的写作技巧,并提供高分范文供参考。
线形图写作核心要点
趋势:线形图的核心是描述数据随时间的变化趋势,如上升(increase)、下降(decrease)、波动(fluctuate)或稳定(remain stable)。
2. 比较数据:不同线条或时间点的对比是关键,需使用比较级或最高级。
3. 精准数据引用:选择关键数据点(如峰值、谷值、转折点)进行说明,避免逐点描述。
4. 多样化表达**:避免重复使用相同词汇,灵活运用同义词和句型。
最新数据示例分析
以全球可再生能源发电量(2010-2023)为例,结合国际能源署(IEA)2024年报告数据制作线形图:
年份 | 太阳能发电量(TWh) | 风能发电量(TWh) | 水电发电量(TWh) |
---|---|---|---|
2010 | 32 | 342 | 3,450 |
2015 | 253 | 832 | 3,920 |
2020 | 844 | 1,592 | 4,380 |
2023 | 1,320 | 2,150 | 4,650 |
(数据来源:International Energy Agency, Renewables 2024)
趋势描述示例:
- 太阳能:从2010年的32 TWh飙升至2023年的1,320 TWh,增长超过40倍,尤其在2020年后增速加快。
- 风能:稳步上升,2023年达到2,150 TWh,是2010年的6倍以上。
- 水电:增长平缓,2023年比2010年增加约35%,增速远低于太阳能和风能。
高分范文
The line graph below shows the global electricity generation from solar, wind, and hydropower between 2010 and 2023. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
范文:
The line graph illustrates changes in global electricity production from three renewable sources—solar, wind, and hydropower—from 2010 to 2023.
Overall, solar and wind power experienced significant growth, while hydropower showed a more gradual increase. Solar energy surged from just 32 TWh in 2010 to 1,320 TWh in 2023, becoming the fastest-growing source. Wind power also expanded steadily, rising from 342 TWh to 2,150 TWh over the same period. In contrast, hydropower’s growth was modest, climbing from 3,450 TWh to 4,650 TWh.
Notably, solar power’s growth accelerated after 2020, with an annual increase of nearly 160 TWh. Wind energy maintained a consistent upward trend, doubling its output between 2015 and 2023. Hydropower, despite being the largest contributor throughout the period, grew by only 35% in 13 years.
By 2023, wind had overtaken hydropower in annual growth rate, while solar’s share rose from less than 1% to over 10% of total renewable generation.

数据引用句式
- “Peaking at 2,150 TWh in 2023, wind power surpassed hydropower in growth rate.”
- “Solar generation, which stood at merely 32 TWh in 2010, skyrocketed to 1,320 TWh by the end of the period.”
-
避免常见错误
- 不要遗漏单位(如TWh)。
- 避免主观猜测原因(如政策影响),除非题目要求。
个人观点
线形图写作的高分关键在于清晰的数据对比和流畅的逻辑,考生应优先描述最显著的趋势,用数据支撑观点,而非机械罗列数字,多练习不同主题的图表,积累行业术语(如能源、人口、经济类词汇),考试时才能游刃有余。
