- 最高值、最低值及变化幅度最大的数据。
- 趋势相似或相反的数据组。

趋势描述词汇
- 上升趋势：increase, rise, grow, climb, surge
- 下降趋势：decrease, decline, drop, fall, plummet
- 波动趋势：fluctuate, vary, experience ups and downs

高分范文
The bar chart below shows the consumption of five energy sources in a country from 2000 to 2020.
范文：
The bar chart illustrates changes in the usage of five types of energy (coal, oil, natural gas, nuclear, and renewables) in a particular nation between 2000 and 2020.
Overall, fossil fuels (coal, oil, and natural gas) dominated energy consumption throughout the period, though their usage patterns varied. Meanwhile, nuclear and renewable energy showed gradual growth but remained minor sources.
In 2000, coal was the most consumed energy, at 50 million tonnes, followed by oil (40 million tonnes) and natural gas (30 million tonnes). Over the next two decades, coal use fluctuated before dropping to 35 million tonnes by 2020. Oil consumption experienced a steady decline, falling to 25 million tonnes, while natural gas saw a significant rise, reaching 45 million tonnes and becoming the primary energy source.
In contrast, nuclear and renewables started at much lower levels (5 million and 2 million tonnes respectively). Nuclear energy grew moderately to 15 million tonnes, whereas renewables surged to 20 million tonnes, reflecting increased investment in sustainable energy.
常见错误
- 数据误读：混淆上升与下降趋势，或错误计算百分比变化。
- 过度描述：试图涵盖所有数据，导致文章冗长且重点模糊。
- 时态错误：动态图表通常使用过去时或现在完成时，但考生可能误用现在时。
- 词汇重复：频繁使用“increase”“decrease”等基础词汇，缺乏多样性。
备考建议
- 多练习动态图表：熟悉线图、柱图、饼图的写作方法，掌握数据分组技巧。
- 积累高分表达：背诵趋势描述短语及数据比较句型，避免重复用词。
- 限时训练：严格控制在20分钟内完成写作，提升时间管理能力。
雅思小作文的核心在于清晰、准确地呈现信息，通过系统练习和技巧运用，考生完全可以在短期内显著提升分数。
