开头段

The line graph compares four cellphone plan providers in terms of their average monthly prices in a European country over a period of 9 months, starting from December in 2011 to August in 2012.

概述段

It is clear that Demo remained to be the most expensive option over the given period, while ETX was the most economical one. Also, the monthly cost of services provided by Demo experienced the most remarkable growth.

思路要点：
- Demo(蓝色)数据始终，ETS(黄色)数据始终
- Demo(蓝色)数据变化幅度

Body paragraph 1

We can f i n d that people had to pay more if they signed a contract with Demo or Alpha. Originally，Demo charged €22 for their monthly plan, after which this figure underwent a slight decrease by €2 in February. Subsequently, there emerged a significant rise to the peak at €33 in July, before dropping marginally to €30 in August. Likewise, the first month witnessed a modest fall in the price of Alpha from €18 to €16. After minor fluctuations, this figure grew noticeably to €26 by the end of the period.

思路要点：蓝色、橙色(数值整体较高)
- 蓝色、橙色数据整体较高
- Demo（蓝色）：一开始€22→2月小幅度下降了€2→7月显著上升到€33→8月小幅度下降到€30
- Alpha（橙色）：个月从€18小幅度下降到€16→随后小幅度波动，到8月显著上升到€26

Body paragraph 2

However, services provided by the other companies were relatively cheaper. With the price of €16, Silm ranked the third place among the four providers in the beginning. Subsequently, this figure saw a period of fluctuations, ranging from €12 to €17. A similar trend could be found in the charge of ETX plans. Starting at €8, its figure declined gradually to €6 in March. Afterwards, this figure more than doubled in June, followed by a dramatic decrease to €8 in the end.  

思路要点：灰色、黄色(数值整体较低)
- 灰色、黄色数据较低
- Silm（灰色）：一开始排第三(€16)→随后在€12 到€17范围内波动
- ETX（黄色）：一开始€8→随后逐步下降，3月达到€6→随后到6月翻倍→8月急剧下降到€8
