四、完整段落示例（套用模板）
题目：某国1990-2010年三种能源消耗量（煤炭、石油、天然气）变化
Introduction:
The table illustrates how much coal, oil and natural gas were consumed in a particular country over the two-decade period from 1990 to 2010.
Overview:
Overall, coal and oil experienced contrasting trends, with the former rising steadily and the latter falling dramatically. Natural gas, by contrast, remained relatively stable throughout the period.
Body 1:
In 1990, coal consumption stood at 50 million tonnes, which was the highest figure among the three categories. Over the subsequent 20 years, this amount increased gradually to 75 million tonnes by 2010, representing a rise of 50%.
Body 2:
Oil, however, showed the opposite trend. Starting at 60 million tonnes in 1990, it plummeted continuously, reaching a low of merely 20 million tonnes by the end of the period. Natural gas, meanwhile, fluctuated marginally between 30 and 35 million tonnes, showing no clear overall direction.
五、动态表格图特别注意
1. 时间顺序：动态图必须按时间线组织，避免按类别横向跳跃
2. 起点终点：务必提及起始值和终点值，计算变化幅度
3. 极值点：如有峰值（peak）或谷值（bottom out），必须指出具体年份和数值
4. 交叉点：如某类别超过另一类别，使用"overtake/surpass"等词强调
5. 倍数关系：增长至两倍用"double"，三倍用"triple"，避免啰嗦
