电力来源比较

✍️ 参考范文

The four pie charts compare the proportions of electricity generated from three different sources (fossil fuels, hydropower, and nuclear power) in India, Sweden, Morocco and Vietnam over the period from 2003 to 2008. Overall, fossil fuel was the dominant source of electricity in all four nations, while nuclear power contributed the smallest share in India and Sweden, and was not used for power production in Morocco and Vietnam. In detail, Morocco relied most heavily on fossil fuels, which accounted for 95% of its electricity generation, followed by India where 82% of power came from this source. By contrast, hydropower made up a larger share of electricity in Sweden and Vietnam, at 44% each, compared to only 14% in India and a mere 5% in Morocco. It is also notable that nuclear power only contributed a tiny 4% to electricity production in both India and Sweden, whereas this energy source was not utilised at all in Morocco and Vietnam during the given period.

审题与结构规划
本题为静态饼图类雅思小作文,需要描述4个国家的电力来源构成,写作结构遵循标准小作文结构:开头段改写题目,概述段总结最突出的整体特征,主体段分点对比细节数据。
开头段处理
同义改写题干信息,将原句的show the sources of the electricity produced in four countries改写为compare the proportions of electricity generated from three different sources (fossil fuels, hydropower, and nuclear power) in India, Sweden, Morocco and Vietnam over the period from 2003 to 2008,明确说明图表类型、对比对象、核心指标和时间范围。
概述段提炼核心特征
首先提炼最显著的共性:化石燃料在所有国家都是占比最高的电力来源;其次提炼差异特征:核能仅在印度和瑞典有极低占比,在摩洛哥和越南完全没有使用。这两个特征覆盖了图表的整体规律,符合overview的要求。
第一组对比化石燃料的占比差异
按照占比从高到低排序,摩洛哥的化石燃料占比最高(95%),其次是印度(82%);之后对比水电的占比,瑞典和越南的水电占比一致(均为44%),远高于印度的14%和摩洛哥的5%,形成清晰的对比逻辑。
第二组补充核能的数据
说明印度和瑞典的核能占比均为4%,是最小的电力来源,而摩洛哥、越南没有使用核能发电,完成所有数据的覆盖,同时避免机械罗列数据,所有数据都伴随对比逻辑。
语言合规性检查
使用多样化的表达描述占比(account for, make up, contribute to, a share of),使用对比连接词(by contrast, compared to, whereas, it is also notable)体现逻辑,没有添加图表以外的主观信息,符合雅思小作文的评分要求。
