Thirst for Oil Burning wood satisfied most energy needs until the steam-driven industrial revolution，when energy-dense coal became the fuel of choice.Coal is still used，mostly in power stations，to cover orle quarter of our energy needs，but its use has been declining since wc Staned pumping up oil.Coal is the least efficient，unhealthiest and most environmentally damaging fossil fuel，but could make a comeback，as supplies are still plentiful;its reserves are five times larger than oils. The majority of oil Comes from the Middle East，which has half of known reserves.But other significant sources include Russia，North America，Norway，Venezuela and the North Sea.Alaskas Arctic National Wildlife Refuge1 could be a major new US source，to reduce reliance on foreign imports. Since we started using fossil fuels，we have released 400 billion tonnes2 of carbon，and burning the entire reserves could eventually raise world temperatures by 13℃.Among other horrors，this would result in the destruction of all rainforests and tile inching of all Arctic ice. Alaskas Arctic National Wildlife Refuge：美国阿拉斯加北极国家野生动物保护区。2001年，美国众议院通过了一项基于布什提出的在那里进行石油开采的议案。该议案遭到环境保护主义组织的反对。因此，目前在该区禁止开采石油。 练习： A Most of the energy on Earth comes from the Sun. C Demand for oil is increasing all the time. Which of lhe following statements is NOT meant by the author，according to the second paragraph? B The use of coal is declining. D Coal reserves are plentiful and will be likely to become the major fuel of Which country is the biggest consumer of petroleum? B Russia. D Venezuela. A The earths fuel reserves will be accessible for the next 50 years. C Conventional reserves will soon become inaccessible. What is NOT the result of consuming fossil fuels according to the last paragraph? B Arctic ice will be melted. D The sea level will go up. 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A、B、D均是作者的意思，而C不是。ncxt to oil除石油以外。 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。 |
