思路解析:
1. 分段原則為:每條線一段,如果多于三條線,則趨勢相似的分為一段。
2. 開頭段需要改寫題目,且進行總體趨勢描述。
3. 按照時間軸的推進順序進行描述。
4. 一類數據(Max, Min, 交點)需要重點描述,、。
5. 注意句式的多樣性,如在表達改變的過程中,下文采用了名詞和動詞的交替使用。
6. 注意靈活的使用近義詞進行詞匯替換。

The graph shows oil prices in dollars per barrel from 1995 with forecasts to 2015. Overall, oil prices increased by nearly four hundred percent from 1995 to 2008, with the most dramatic increase in the two years from 2006 to 2008. This rise is predicted to continue into the future.(開頭段改寫題目,并且描述總體趨勢)
Prices started at around twenty US dollars a barrel during 1995, and then rose slightly to approximately twenty-four dollars in 1998. (起點+動作1,注意動作+幅度)
The cost of a barrel then dropped for two years, to the lowest point of about eighteen dollars during 2000. (Min, 一類數據必描述,注意數據雙重性,同時注意cost=price,同替換義)After that, there was a steady price rise, reaching about fifty dollars a barrel in 2006. (there be 句式,名詞化表達,句式多樣性)
This was followed by a dramatic climb to over ninety dollars in 2008, and it is forecasted that this rise will continue into the future, and will level off slightly after 2010, with expectedly ending up at 130 price by 2015. (follow by 句式,名詞化表達,注意描述數據的將來式應該用forecast, expect等表預測的詞匯,結尾用end up)
