开头段
The bar chart compares the monthly precipitation in five Chinese cities(Beijing, Shanghai, Guangzhou, Chengdu, and Urumqi) across three months(March, June, and September) in 2020.
概述段
Overall, Guangzhou received the highest rainfall in most months, whereas Urumqi remained the driest city throughout the period. In addition, June recorded the highest precipitation across all five cities.
思路要点：
- 广州的降雨量整体比其他城市高，乌鲁木齐降雨量始终最·低
- 六月所有城市降雨量都最·高
Body paragraph 1
In March, rainfall levels were relatively low in most cities except Shanghai, which recorded approximately 120 mm, closely followed by Guangzhou at 80 mm. Chengdu received 30 mm of rainfall, twice that of Urumqi. In contrast, Beijing recorded only 10 mm, the lowest among all the five cities.
思路要点：三月
- 所有城市降雨量都较低
- 上海：是五个城市中降雨量最·高的(120mm)，Guangzhou排第二(80mm)
- 成都：降雨量为30mm，是Urumqi的两倍
- 北京：降雨量最小，仅为10mm
Body paragraph 2
Subsequently, the rainfall in Guangzhou and Shanghai jumped to a peak of 280 mm and 180 mm in June, before falling dramatically to 170 mm and 90 mm in September. Similarly, after a fivefold increase to the highest level at 150 mm in June, the precipitation of Chengdu dropped slightly to 120 mm in September. Despite the above fluctuations, these three cities continued to maintain higher levels of rainfall.
思路要点：广州、成都、上海（六月、九月）
- 广州、上海：六月急剧上升到280mm和180mm→九月急剧下降到170mm和90mm
- 成都：六月上涨5倍达到150mm→九月小幅度下降到120mm
- 尽管数值有波动，以上三个城市降雨量仍然较高
Body paragraph 3
However, the precipitation in the other two cities was much lower. Beijing’s rainfall level surged to 80 mm in June, followed by a noticeable decrease to 50 mm after three months. In comparison, the rainfall in Urumqi remained consistently low, keeping stable at roughly 30 mm in both June and September.
思路要点：北京、乌鲁木齐（六月、九月）
- 北京、乌鲁木齐降雨量较低
- 北京：六月急剧上升到80mm→九月显著下降到50mm
- 乌鲁木齐：数值一直较低，六月、九月降雨量保持平稳在30mm左右
