The bar chart compares the cost of an average house in five major cities over a period of 13 years from 1989.
We can see that house prices fell overall between 1990 and 1995, but most of the cities saw rising prices between 1996 and 2002. London experienced by far the greatest changes in house prices over the 13-year period.
During the 1990–1995 period, the cost of average homes in Tokyo and London dropped by around 7%, while New York house prices went down by 5%. By contrast, prices rose by approximately 2% in both Madrid and Frankfurt.
Between 1996 and 2002, London house prices jumped to around 12% above the 1989 average. Homebuyers in New York also had to pay significantly more, with prices rising to 5% above the 1989 average, but homes in Tokyo remained cheaper than they were in 1989. Average prices in Madrid were around 4% above the 1989 level, compared with approximately 2% in the earlier period. Frankfurt remained above the baseline, but its increase was smaller in the later period.

对象、地点、时期与图表数量随题目变化。用熟悉表达准确改述即可。

有时间轴才描述变化。from 是起值，to 是终值，by 是变化量；不必强行把所有线写成相反走势。
03 · 细节 · 用信息支撑概述
按两个时间区间分段，每段比较城市相对1989年的位置。
可用骨架
The figure rose / fell from… to… between… and…
本题原句
During the 1990–1995 period, the cost of average homes in Tokyo and London dropped by around 7%, while New York house prices went down by 5%.
从-5%到+10%是相对基年差值变化15个百分点，不能直接说实际房价上涨15%。
选择与组织 · 为什么这样写
先找关键特征
早期多城低于基年；后期多数恢复；伦敦变化较大。
怎样决定分组
按两个时间区间分段，每段比较城市相对1989年的位置。
为什么这样选择
先读零基线，再看城市差异；正负柱表示相对基年，不一定是区间内部连续上涨或下降。
语言与精度 · 本节重点
从-5%到+10%是相对基年差值变化15个百分点，不能直接说实际房价上涨15%。
最后练一练 · 先组织，再写
读熟后，可以先遮住参考，回忆本节最有用的两三句。想动笔时再打开下方写作台，不需要首次学习就完成全文。
定点练习
解释“+10%”相对的是哪一年。
写完后看一种参考处理
Prices were approximately 10% above their 1989 level.
检查它修正了什么意义或关系。可以使用不同措辞，但信息需要准确。
换题使用
本站自编文字数据 · 与上方原题分开
自编数据，相对2010基年：甲城2011–2015为-5%、2016–2020为+10%；乙城分别为-2%、+3%；丙城为+2%、+1%。写两句概述并比较甲城。
先试一段，再视需要写全文。将新内容写在写作台的“迁移”中；原稿留在“初稿”，修订另存到“修改”。图表题需要重新识别特征，书信与议论文需要重新回应任务。
