Thirst for Oil Werldwide every day,we devour the energyequivalent of about 200 million barrels of Oil.MoHt of the energy on Earth comes from the Sun.In fact enough energy from the Sun hits the planets 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. Today petroleum,a mineral oil obtained from below the surface of the Earth and used to produce petrol,diesel oil and various other chemical substances,provides around 40% of the worlds energy needs,mostly fuelling automobiles.The US consumes a quarter of all oil,and generates a similar proportion of greenhouse gas emissions. 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 become more difficuh to access.others such as oil shales and tar sands may be used instead.Petrol could also be obtained from coal. 词汇: denseadj.密集的 diesel oil 柴油 可得到的5petrElp reliancen.依赖,依靠 tar sand 沥青砂 注释: 2. tonnes:公吨。不同于ton。 ton:在美国等于二千磅,所以称作short ton:短吨。 1. ...we will need to cure our addiction to oil. Why does the author say so? B Oil supply is increasing all the time. D Oil supply is decreasing. A Wood wets the fuel of choice before coal. C Coal is the most environmentally unfriendly fuel next to oil. choice. A The United States. C Norway. 4. What do experts say about the earths fuel reserves? B There will soon be an energy crisis. D Fuel demand will decline. A Rainforests will be destroyed. C The earths temperature will be raised. 答案与题解: 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A、B、D均是作者的意思,而C不是。ncxt to oil除石油以外。 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。
