题目：动态柱状图（1990-2020年某国三种能源消费比例变化）
范文：
The bar chart illustrates the changes in the proportion of three energy sources (coal, natural gas, and renewable energy) consumed in a particular country between 1990 and 2020.
Overall, coal remained the dominant energy source throughout the period, despite a gradual decline. In contrast, the use of natural gas and renewable energy showed an upward trend, with renewables experiencing the most significant growth.
In 1990, coal accounted for 60% of total energy consumption, far exceeding natural gas (30%) and renewables (10%). Over the next decade, coal usage dropped by 10%, while natural gas rose to 35%. Renewables also increased slightly to 15%.
By 2010, coal’s share had further decreased to 45%, whereas natural gas reached 40%. Notably, renewable energy doubled its proportion to 20%. The most dramatic shift occurred in the final decade (2010-2020), with coal falling to 35% and renewables surging to 30%, nearly catching up with natural gas (35%).
This trend suggests a gradual shift from fossil fuels to cleaner energy, likely driven by environmental policies and technological advancements.
高分技巧解析
结构清晰，逻辑连贯
雅思小作文的核心是客观描述,无需主观分析，范文采用经典四段式：
- 引言段：改写题目，明确图表内容。 段**：总结核心趋势（不写细节）。
- 细节段：分阶段描述数据变化，突出对比。
- 结尾段：自然收束，避免强行总结。
关键点：
- 动态图（含时间变化）需强调趋势（上升/下降/波动）。
- 静态图（无时间变化）需比较数据差异。
词汇精准，避免重复
- 上升：increase, rise, grow, surge
- 下降：decrease, decline, drop, fall
- 波动：fluctuate, vary
- 占比：account for, represent, constitute
例句优化：
- 原句：Coal went down from 60% to 35%.
- 优化：Coal consumption plummeted by 25% over three decades.
句式多样，语法准确
避免简单句堆砌,灵活使用：
- 比较级：Natural gas usage was higher than renewables.
- 被动语态：Coal was gradually replaced by cleaner alternatives.
- 分词结构：Starting at 10%, renewables tripled by 2020.
常见错误规避：
- 时态错误：动态图用过去时（1990-2020），未来预测用将来时。
- 数据误读：确保百分比与绝对数区分清楚。
衔接自然，提升流畅度
使用逻辑连接词：
- 对比：however, in contrast, whereas
- 顺序：initially, subsequently, finally
- 结果：as a result, consequently
考生常见问题解答
Q1：是否需要写结论？
A：小作文无需结论，但可用一句话点明趋势（如范文最后一句）。
Q2：数据太多，如何筛选？
A：优先描述极值（最高/最低）、转折点（趋势变化年份）、显著对比（差距拉大/缩小）。
Q3：能否使用模板句？
A：可适度使用（如“The chart illustrates…”），但需结合题目灵活调整，避免生硬。
