今天练一篇小作文，柱状图，动态图。
题目
You should spend about 20 minutes on this task.
The chart below shows the number of households in the US by their annual income in 2007, 2011 and 2015. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
我自己写的版本就不看了，下面是让 GPT 给我修改的版本：
The bar chart illustrates the distribution of US households across various annual income brackets for the years 2007, 2011, and 2015.
Overall, the data reveals a relatively stable trend in the number of households across the income spectrum, with minor fluctuations observed over the eight-year period. A bimodal distribution is evident, with the majority of households falling into either the lower or higher income categories.
In detail, households with an annual income below $25,000 experienced a marginal increase from approximately 25 million in 2007 to around 27 million by 2015. A similar, albeit slightly less pronounced, trend was observed for those earning between $25,000 and $49,999 annually. In contrast, the number of households with a middle income range of $50,000 to $74,999 remained relatively constant, hovering around the 20 million mark.
Comparatively, the number of households with an annual income between $75,000 and $99,999 was notably smaller, with figures remaining at approximately 15 million, showing little change. However, the most affluent households, with incomes exceeding $100,000, were the most part, with their numbers fluctuating around the 30 million mark and peaking at about 33 million in 2015.

改写段
The bar chart illustrates the distribution of US households across various annual income brackets for the years 2007, 2011, and 2015.
第一段对题目进行改写，根据句子的不同成分改写以下内容：
- 细化图表的具体类型：bar chart
- 润色“展示”这个动词：illustrate
- “展示”动词的改写应该根据图表的类型和内容来判断，是一种比较（compare），还是单纯的描绘（illustrate），应该要学会恰当地使用而不是不加思考地换词
- 换更高级的方式表达描述对象：the distribution of US house holds
- 改写描述对象依靠的是一种总结与概括，题目只是说展示了家庭的数字，但更加概括性地说，它分成了不同收入人群，所以这是一种分布（distribution）
- 修改描述对象的修饰语：across various annual income brackets
- 题目只是简单地说 by their annual income，这里换成了在不同的收入区间中（across various annual income brackets）。跨越不同的时间、等级、分段，都可以用 across。bracket 和 interval 是一个意思，数学上称之为区间
- 换一种方式表达时间状语：for the years 2007, 2011, and 2015
- 题目里是很直白地说 in 2007, 2011, and 2015
图表类型 => 展示动词 => 描述对象 => 修饰语（地点状语） => 时间状语
概述段
第二段是概述段，一般写两句话。一句话写趋势上的变化（对于动态图），另一句话写数值上的特征。
第一句话先写横坐标不同年份上的特征，我想的是这三年以来不同收入群体变化趋势几乎不变，整体上看没有很明显的增加或减少趋势：
Overall, the data reveals a relatively stable trend in the number of households across the income spectrum, with minor fluctuations observed over the eight-year period.
- 呈现出一种相对稳定的趋势：reveals a relatively stable trend in the number of households across the income
- reveal 呈现，揭示；a relatively stable trend 相对稳定的趋势；in the number of households across the income 对于描述对象而言
第二句话再写每年不同区间之间的特征，我想的是两极分化比较严重，中间低两边高
A bimodal distribution is evident, with the majority of households falling into either the lower or higher income categories.
- 两极分化，可以表达为双峰分布：a bimodal distribution
- 继续补充说明，双峰是哪双峰：with the majority of households falling into either the lower or higher income categories
- with the majority of (households) ... 大部分(家庭)怎样怎样
- falling into either the lower or higher income categories 大部分都要么是低收入要么是高收入
细节段
细节段一般写两段，首先根据一定的分组逻辑来将数据分为两组或三组，一段一组。分组的时候要尽量跟概述段有一定的联系。
第一段主要写低收入到中收入这部分人群的变化趋势。先看第一段第一句，写收入最低的第一个区间：
In detail, households with an annual income below $25,000 experienced a marginal increase from approximately 25 million in 2007 to around 27 million by 2015.
- 细节段开头都要有承上启下的引导词，第一段引导词这里使用 In detail
- 比较对象是区间如何表达：households with an annual income below ... / above ... / between ... and ... ，不要再只会 from to 了。
- 比较对象 saw ... 可以用 experienced ... 代替更高级
- 描述上升或下降的时候不要再只有一个上升或下降，要有修饰语，是缓慢的还是剧烈的还是平稳的还是波动的：a marginal increase
- households with an annual income below $25,000 experienced a marginal increase
- 然后再接具体的数值变化情况：from somenumber in sometime to somenumber in sometime，但是中间还可以给数字增加大约、大概的修饰语，比如 approximately, around, about
第一段第二句写倒数第二段的区间，跟第一段变化趋势相近：
A similar, albeit slightly less pronounced, trend was observed for those earning between $25,000 and $49,999 annually.
- A similar trend was observed for ... 对于某某有一个相似的趋势，多用 observed
- those earning between 49,999 annually 换一种表示年收入的说法
- albeit slightly less pronounced 尽管可能不是很明显，作插入语
第一段第三句写中等收入区间，基本上没有变化：
In contrast, the number of households with a middle income range of $50,000 to $74,999 remained relatively constant, hovering around the 20 million mark.
- In contrast 相比之下。因为是基本不变，跟前面的增长趋势不同
- the number of households with a middle income range of $50,000 to $74,999 由于跟前面对比，又要把比较对象（number）写完整，用 with 来表明范围
- hovering around the 20 million mark 悬停在大约 20 million 处，写明具体数字
第二段写高收入人群。第二段第一句先将倒数第二个区间的情况：
Comparatively, the number of households with an annual income between $75,000 and $99,999 was notably smaller, with figures remaining at approximately 15 million, showing little change.
- 相比之下 Comparatively 作为引导词
- notably smaller 数量非常少，数字非常小，明显更小
- 说具体数字 with figures remaining at approximately 15 million
- showing little change 有一定的变化
However, the most affluent households, with incomes exceeding $100,000, were the most part, with their numbers fluctuating around the 30 million mark and peaking at about 33 million in 2015.
- 最富有的家庭 the most affluent households
- with income exceeding ... 超过。。的收入
- with their numbers fluctuating around the 30 million mark 在。。附近波动 fluctuate around ...
- peaking at ... 达到。。。的峰值
