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 comeback, 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 produce 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 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. 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 become more difficult to access, others such as tar sands may be used instead. Petrol could also be obtained from coal.
Since we started using fossil fuels ,we have released 400 billion tones 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.
"… we will need to cure our addiction to oil." Why does the author say so？
A．Most of the energy on Earth comes from the Sun.
B．Oil supply is increasing all the time.
C．Demand for oil is increasing all tile time.
D．Oil supply is decreasing.
Thirst for Oil
Worldwide every day, we devour the energy equivalent of about 200 million barrels of oil. Most of the energy on Earth comes 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.

听力原文： The year is 2501, and the Earth is desperately short of fuel. All Earth's coal, oil and wood have been used up long ago, and scientists have been sent to the ends of the universe in search of alternative forms of energy.
A rich and powerful civilization has been discovered on the planet Jupiter, and Earth is supplied with fuel by constant supply fleets from that planet, but the price is very high. Unless it discovers an alternative source of energy soon, civilization on Earth will fail, and its inhabitants will have to move to other planets where they will be little more than slaves. Then Jupiter will take possession of Earth-- the most beautiful, most desirable planet in the universe.
Human scientists have been sure for a long time that Jupiter possesses a method of creating constant energy and now ten explorers on a secret mission from Earth have discovered the secret--a kind of heavy, green dust which will change salt water to high grade petroleum. This dust covers a large part of Jupiter's surface, and just a few pounds of it could solve the world's energy crisis since it would reproduce itself continuously in Earth's atmosphere.

The Finnish history began in the Middle Ages. In about 1155, Finland Was conquered by its western neighboring Sweden. After a period of rule by Denmark in the 14th century, the Swedes won back independence and power in 1523 under their brave king, During the Napoleonic Wards (1814 -1818), Finland was passed finally from Sweden to Russia. The opportunity came in 1917, when the Russian Revolution brought foreign rule of Finland to an end. Shortly after Soviet Russia made peace with Germany, 1919 saw the founding of the Finnish Republic.
The years between the First and Second World Wars were years of progress and growing development. Finland has no coal or oil, and the nation's wealth lies in the timber (wood prepared for use in building, etc. ) from its forests, which supplies material for paper and furniture making, and in the electric power from its water.
How much of Finland's surface is covered with thick forests？
A．About 67%.
B．About 50%.
C．100%.
D．66%.
A. Wood wets the ruel of choice before coal．
B. The use of coal is declinin9．
C. Coal is the most environmentally unfriendly fuel next to oil．
D. Coal reserves are plentiful and will be likely to become the major fuel of choice．
