| 年份 | 煤炭 | 天然气 | 可再生能源 |
|---|---|---|---|
| 2000 | 150 | 80 | 20 |
| 2005 | 180 | 100 | 25 |
| 2010 | 160 | 130 | 40 |

The table illustrates changes in the consumption of three energy sources (coal, natural gas, and renewable energy) in a particular country from 2000 to 2020, measured in million tonnes of oil equivalent.
Overall, coal usage experienced a decline over the two decades, whereas natural gas and renewable energy saw consistent growth. Renewable energy, despite starting from the lowest base, demonstrated the most significant increase by 2020.
In 2000, coal was the dominant energy source, with consumption at 150 million tonnes, far exceeding natural gas (80 million tonnes) and renewables (20 million tonnes). Over the next five years, coal usage rose to 180 million tonnes, while natural gas increased to 100 million tonnes, and renewables reached 25 million tonnes.
However, from 2010 onwards, coal consumption began to decrease steadily, dropping to 160 million tonnes in 2010 and further declining to 120 million tonnes by 2020. In contrast, natural gas showed a steady upward trend, reaching 130 million tonnes in 2010 and peaking at 170 million tonnes in 2020.
The most striking change occurred in renewable energy. Starting at just 20 million tonnes in 2000, it grew gradually to 40 million tonnes in 2010 before surging to 90 million tonnes by 2020. This fourfold increase highlights a significant shift towards sustainable energy in the country.
By 2020, natural gas had overtaken coal as the primary energy source, while renewables, though still the smallest contributor, showed the highest growth rate.
写作技巧解析
开头段：明确图表内容
- 直接点明图表主题、时间范围及数据单位。
- 避免照抄题目，用同义替换（如“illustrates”代替“shows”）。
概述段：提炼核心趋势
- 用1-2句话总结整体变化，突出最显著的特征。
- 本例中，煤炭下降、天然气和可再生能源上升是核心趋势。
主体段：分段描述数据
- 时间顺序法：按时间推进分段（如2000-2005、2010-2020）。
- 类别对比法：分能源类型描述（如煤炭趋势、天然气趋势）。
- 本例结合两种方法，先按时间分阶段，再对比不同能源的变化。
数据选取与对比
- 不必描述所有数据，选择起点、终点、峰值、转折点等关键信息。
- 使用比较级（如“far exceeding”“overtook”）和倍数表达（如“fourfold increase”）。
语言多样性
- 趋势动词：rise, decline, surge, peak, drop.
- 程度副词：steadily, significantly, gradually.
- 衔接词：however, in contrast, whereas.
常见错误与改进建议
-
机械罗列数据：避免逐行复述表格，应归纳趋势。
- 错误写法：“In 2000, coal was 150, gas was 80…”
- 正确写法：“Coal dominated in 2000, accounting for 150 million tonnes, nearly double the figure for natural gas.”
-
忽略单位或时间范围：始终提及数据单位（如million tonnes）和时间段（2000-2020）。
-
过度主观推测：不要猜测数据变化原因（如“因为政策支持”），仅描述客观趋势。
