The line graph compares three companies in terms of their waste output between the years 2000 and 2015.
It is clear that there were significant changes in the amounts of waste produced by all three companies shown on the graph. While companies A and B saw waste output fall over the 15-year period, the amount of waste produced by company C increased considerably.
In 2000, company A produced 12 tonnes of waste, while companies B and C produced around 8 tonnes and 4 tonnes of waste material respectively. Over the following 5 years, the waste output of companies B and C rose by around 2 tonnes, but the figure for company A fell by approximately 1 tonne.
From 2005 to 2015, company A cut waste production by roughly 3 tonnes, and company B reduced its waste by around 7 tonnes. By contrast, company C saw an increase in waste production of approximately 4 tonnes over the same 10-year period. By 2015, company C’s waste output had risen to 10 tonnes, while the respective amounts of waste from companies A and B had dropped to 8 tonnes and only 3 tonnes.

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
A与B作为下降组，C作为上升组；用起点、中间转折和终点解释差异。
可用骨架
The figure rose / fell from… to… between… and…
本题原句
In 2000, company A produced 12 tonnes of waste, while companies B and C produced around 8 tonnes and 4 tonnes of waste material respectively.
废弃物上升不能用improve；减少的数量用fell by，终点用fell to。
选择与组织 · 为什么这样写
先找关键特征
A与B总体减少，C增加；B中途先升后降；终点排名发生变化。
怎样决定分组
A与B作为下降组，C作为上升组；用起点、中间转折和终点解释差异。
为什么这样选择
中间年份只在转折处发挥作用，普通年份可以省略；这让每个数字都有解释任务。
语言与精度 · 本节重点
废弃物上升不能用improve；减少的数量用fell by，终点用fell to。
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
把“B fell to 7 tonnes, from 10 to 3.”改准。
写完后看一种参考处理
Company B's waste output fell by 7 tonnes, from 10 to 3 tonnes.
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。
