共享题干题                                             (三)Thirst for Oil根据材料,回答下列问题。   Worldwide every day, we devour the energy equivalent of about 200 million barrels of oil.Most of the energy on Earth es from the Sun. In fact enough energy from the Sun hits the planet's surface each minute to cover our needs for an entire year, we just need to find an efficient way,to use it. So far the energy in oil has been cheaper and easier to get at. But as supplies dwindle, this will change, and we will need to cure our addiction to 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 one quarter of our energy needs, but its use has been declining since we started pumping up oil. Coal is the least efficient, unhealthiest and most environmentally damaging fossil fuel, but could make a eback, as supplies are still plentiful: its reserves are five times larger than oil's.     Today petroleum, a mineral oil obtained from below the surface of the Earth and used to pro: duce petrol, diesel oil and various other chemical substances, provides around 40% of the world's energy needs, mostly fuelling automobiles. The US consumes a quarter of all oil, and generates a similar proportion of greenhouse gas emissions.    The majority of oil es from the Middle East, which has half of known reserves. But other significant sources include Russia, North-America, Norway, Venezuela and the North Sea. Alaska's Arctic National Wildlife Refuge could be a major new US source, to reduce reliance on foreign imports.    Most experts predict we will exhaust easily accessible reserves within 50 years, though opinions and estimates vary. We could fast reach an energy crisis in the next few decades, when demand exceeds supply. As conventional reserves bee more difficult to access, others such as oil shales and tar sands may be used instead. Petrol could also be obtained from coal.   Since we started using fossil fuels, we have released 400 billion tonnes 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 the melting of all Arctic ice.1.[不定向选择题]"... we will need to cure our addiction to oil.

1.参考答案:D
参考解析:答案在第一段最后一句中。这里的supplies指oil supplies。
2.参考答案:B
参考解析:答案在第2.9二句中。该段第一句说,地球上的燃料储量将在50年内耗尽,所以A不是正确选项;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也不是正确选项;D明显不是作者的意思。3.[不定向选择题]Which country is the biggest consumer of petroleum?A.The United States. B.Russia C.Norway D.Venezuela
