Thirst for Oil

Burning wood satisfied most energy needsuntil the steam-driven industrial revolutionwhen energy-dense coal became the fuel of choiceCoal is still usedmostly in power stationsto cover orle quarter of our energy needsbut its use has been declining since wcStanedpumping up oilCoal is theleast efficientunhealthiestand most environmentally damaging fossil fuelbut could make a comebackas supplies are still plentifulits reserves are five times larger than oils

Today petroleuma mineral oil obtained from below thesurface of the Earth and used to produce petroldiesel oil and various other chemical substancesprovides around 40% of the worlds energy needsmostly fuelling automobilesThe US consumes a quarter of all oiland generates a similar proportion ofgreenhouse gas emissions

The majority of oil Comes from the MiddleEastwhich hashalf of known reservesBut othersignificant sources include RussiaNorth AmericaNorwayVenezuelaand the North SeaAlaska'sArctic National Wildlife Refuge1 could be a major new US sourceto reduce reliance on foreign imports

Most experts predict we will exhaust easilyaccessible reserves within 50 yearsthough opinions and estimates varyWe could fast reach an energy crisis in thenext few decadeswhen demandexceeds supply Asconventional reserves become more difficuh to accessothers such as oil shales and tar sands maybe used insteadPetrolcould also be obtained from coal

Since we started using fossil fuelswe have released 400 billion tonnes2 ofcarbonand burningthe entire reserves could eventually raise world temperatures by 13℃.Among other horrorsthis would result in the destruction of allrainforests and tile inching of all Arctic ice

答案与题解:

1 D 答案在第一段最后一句中。这里的xuppliesoil supplies

2 C 短文的第二段告诉我们,木材曾经是主要燃料来源,然后被煤所替代;白人们开始采油后,对煤的需求下降了,但因为煤的储量远大于石油,它可能又会成为主要燃料,尽管它对环境最具破坏力。所以ABD均是作者的意思,而C不是。ncxt to oil除石油以外。

3 A 文章的第三段说,美国消耗全世界四分之一的石油。

4 B 答案在第五段第二句中。该段第一句说,地球上的燃料储量将在50年内耗尽,所以A不是正确选择;第三句的意思是,常规燃料的获取将变得困难,而不是不可获得,所以C也不是正确选择;D明显不是作者的意思。

5 D 选项ABI:都是最后一段中所表达的意思,所以D是正确选择。
