難句解析：
①Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short time.
▲該句是一個含有插入成分的單句。主語是Strengthening economic growth，謂語是could push，插入成分是一個時間狀語。
△本句閱讀的重點是要首先抓住主句的基本結構。
②In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past.
▲該句是一個復雜句，由兩個單句構成，中間用so來表示前后的因果關系。
△本句閱讀的重點是一些短語和詞組。account for占…的部分；muted原意是“沉默的，被弄啞的”，在文章里的意思是“不太顯著的”；pump price油品零售價格。
③Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption.
▲該句是一個簡單句，只是主語復雜一點，其謂語部分是have reduced oil consumption。
△本句閱讀的重點在主語，注意它里面有三個并列成分：Energy conservation，a shift to other fuels，第三個是a decline in the importance of heavy, energy-intensive industries。
④The OECD estimates in its latest Economic Outlook that, if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25-0.5% of GDP.
▲本句的主句是The OECD estimates... that，本句復雜的地方在其賓語部分，里面有一個條件狀語if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998，而主句是后面的部分，其中的主語this指代的是if條件句。
△本句閱讀的重點在于抓住句子的主干。
⑤One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand.
▲本句的主句是One more reason is that...。比較復雜的是其以that引導的表語從句，它的主語是it，指代的是the rise in oil prices。
△本句閱讀的重點在于了解一些短語的意思：lose sleep over因…而失眠；occur against the background of...發生在…的背景之下。
